Hello, everybody.Happy new year.
I am now preparing to give a
lecture on cell biology for 
my students. I need some materials
on cell signals transduction pathway.
Where can I get the latest reports
or progress and how to download
them? Who knows? Please tell me.
Thanks in advance. Thanks again.

DIRECTOR - BIOMEDICAL ENGINEERING INSTITUTE  
UNIVERSITY OF MINNESOTA

The University of Minnesota seeks a Director for its recently established 
Biomedical Engineering Institute (BMEI). BMEI is the administrative home of 
the graduate degree program in Biomedical Engineering and is a cooperative 
enterprise coordinating the biomedical engineering activities of the Medical 
School and the Institute of Technology (Minnesota's combined college of 
mathematics, physical science and engineering). The Director will report to 
the Deans of these two colleges. The Director will hold an endowed Bakken 
chair professorship.  

BMEI has active research and industrial interaction programs, in addition to 
its responsibility for graduate education. The graduate program (which was 
initiated in 1972) has fifty full-time and twenty part-time students, the 
latter group being drawn largely from the exceptionally broad range of 
biomedical industries in the region. 

BMEI is supported by funds from the recurring operating budget of the 
University of Minnesota, and will be the recipient of the income from an 
on-going, $12 million, endowment campaign which is well on its way to 
completion. The Director should have a recognized reputation for excellence 
in research accomplishments and the ability to lead and administer a growing 
academic enterprise. It is planned that BMEI will grow in staff, both via new 
faculty hiring and by the transfer of appointments of existing faculty into 
BMEI. The Director will be expected to lead the development of BMEI into an 
internationally recognized program of biomedical engineering research, 
education and industrial interaction.  

Interested candidates should send a resume by January 15, 1997 to

Professor Wei-Shou Hu

The first release of a preliminary version of my patch clamp analysis
program is ready for download from my web site sunday 1200 noon. Take a
preview at some of the programs current capabilities at :

http://home.interlynx.net/~lthomsen/hotspot.htm

The program has highly professional graphical routines. The program is not
commercial or shareware, it is simply a help from me to you. The analysis
is not so advanced yet, but Im working hard on fixing that. Right now the
program is a really nice alternative to your PClamp6 graph struggling.

If you want to become a betatester and thereby having some influence on the
future shape of the program then you can download it at Sunday. However,
you need a password to the zip file. You can get the password by sending me
an email.  lthomsen@interlynx.net



See you

hello!
I am trying to understand the relationship of the changes in the
action potential on the ECG.; in particular the changes in Phase 2 and
3 and how if they are shortened or increased do they alter the effect
on the ECG? For example, does shortening phase 2 d/t say ischemia,
decrease the amplitude of the ECG? What happens if these phases (2;3)
are increased or lengthened to the ECG? If there is anyone who has
extensive knowledge in this area and would be willing to answer these
questions and a few others, it would be greatly appreciated. Emailing
me may make this process of communication a little more speedy, so if
you would like, send your info to      trevor@worldy.com          If
there is anyway Ican help you out, please pass it on and I would be

                                 FIRST CALL

                 CRETE COURSE IN COMPUTATIONAL NEUROSCIENCE

                        SEPTEMBER 7 - OCTOBER 3, 1997

                         UNIVERSITY OF CRETE, GREECE

DIRECTORS:    Erik  De Schutter (University of Antwerp, Belgium)
              Idan Segev (Hebrew University, Jerusalem, Israel)
              Jim Bower (California Institute of Technology, USA)
              Adonis Moschovakis (University of Crete, Greece)


The Crete Course in Computational Neuroscience introduces students to 
the practical application of computational methods in neuroscience, in 
particular how to create biologically realistic models of neurons and 
networks.  

The course consists of two complimentary parts.  A distinguished 
international faculty gives morning lectures on topics in experimental 
and computational neuroscience.  The rest of the day is spent learning 
how to use simulation software and how to implement a model of the 
system the student wishes to study.  The first week of the course 
introduces students to the most important techniques in modeling single 
cells, networks and neural systems.  Students learn how to use the 
GENESIS, NEURON, XPP and other software packages on their individual 
unix workstations. During the following three weeks the lectures will 
be more general, but each week topics ranging from modeling single cells 
and subcellular processes through the simulation of simple circuits, 
large neuronal networks and system level models of the the brain will
be covered. The course ends with a presentation of the students' 
modeling projects.

The Crete Course in Computational Neuroscience is designed for advanced 
graduate students and postdoctoral fellows in a variety of disciplines, 
including neuroscience, physics, electrical engineering, computer science 
and psychology.  Students are expected to have a basic background in 
neurobiology as well as some computer experience.  A total of 28 students 
will be accepted with an age limit of 35 years.  We will accept students
of any nationality, but the majority will be from the European Union
and affiliated countries (Iceland, Israel, Liechtenstein and Norway).  
We specifically encourage applications from researchers who work in 
less-favoured regions of the EU, from women and from researchers from 
industry.  

Every student will be charged a tuition fee of 500 ECU (approx. US$630).
In the case of students with a nationality from the EU, affiliated 
countries or Japan, the tuition fee covers lodging, local travel and all 
course-related expenses.  All applicants with other nationalities will 
be charged an ADDITIONAL fee of 1000 ECU (approx. US$1260) which covers 
lodging, local travel and course-related expenses.  For nationals from 
EU and affiliated countries economy travel from an EU country to Crete 
will be refunded after the course.  A limited number of students from 
less-favoured regions world-wide will get their fees and travel refunded.

Greetings!

   We're (or rather, my PhD supervisor is..) looking for the conditions
necessary to observe the C-form of DNA in solution. So far, all we have
found in the literature are the conditions necessary for the C-form in
solid fibres, but da boss swears he's seen an article on the C-form of DNA
in solution *somewhere*. So, does anyone out there know of a handy
reference, or do they have the conditions (what concentration of what ions
etc ) ? Please?

Thanks in advance for any help you can give. Email would probably be the
best medium for a reply, unless others show an interest on this group.

  Hi there.

  Have a look at F.M. Pohl, "Polymorphism of a Synthetic DNA in
  Solution", Nature, vol. 260, 365 (1976). Pohl says the C-form
  of DNA is found at [CsCl]=7.1 M or [LiCl]=3.8 M.

  My Ph.D. is about the simulation of the B->Z DNA transition.
  Contact me if that fancies you.

  Regards.

I am searching for a small independently folding (or in presence of a
metal ion), DNA binding domain. Would like it to be sequence specific, but
would greatly appreciate all suggestions. Be as detailed as possible or
please cite a reference, or name that I can locate it in the literature.
Thanks very much.

The idea of a qualifying exam is for you to prove that you can come up
with an original proposal on your own and then successfully defend it.
Anyone that gives you an idea is doing you, as well as the rest of
the research community, a disfavor. A PhD is supposed to imply that you
are capable of original thought. If I knew your proposal resulted from a
request of this sort, no matter how good it was, I would fail you on the spot.

The Kd value that you have listed for the minimal portion of "BPV-E2 
DNA binding domain" binding it's cognate site is very different from 
that which has been published.

For instance, from J. Virol. 71:828-831 (1997) (a publication from
the Androphy lab), the Kd of the 87 a.a minimal DNA binding domain 
for it's cognate site is listed as approximately 7.0 nM (i.e. 7 x 10e-9 M), 
while a larger fragment, containing 127 a.a has a Kd of about 0.9 nM, 
and even this is quite far from the picomolar affinity you have listed ....

Later,

Hello!
Well, the Bovine Papillomavirus DNA binding domain (minimal) iosonlt 85 AA
although tit forms a dimer.  It has the aadvantage of many characterized
mutations, and an excellent crystal structure (1.2A) and  binds
sequence-specific to a palindropme at 10 -12 M.

I also study it!

It has come to my knowledge that G proteins undergo phosphorylation by
cAMP- and calcium-dependent protein kinases and by tyrosine kinases.

Having undertaken the writing of a part of a seminar on autonomic NS
pharmacology, I was wandering if anyone out there knew something about the
physiological role of G protein phosphorylation, especially in relation to
neurotransmission and synaptic plasticity processes. Any details on the
phosphorylation sites and regulation are also welcome. References to book
chapters or journal articles are welcome.

Thank you in advance.

Umm, I know nothing about DNA binding, but biology is not a quantitative 
science, so 3 orders of magnitude makes no difference (since nobody knows 
how to apply those numbers anyway).

I'm having problems with precipitation forming in a Tris 
Buffer with LaCl3.  The precipitate forms slowly on the gas-liquid
interface and is apparent after a period of 12-24 hours.  The 
formation of the precipitate is pH dependent.  Precipitation does 
not occur at pH below approximately 6.7.  The amount of precipitation 
increases with increasing pH.  Furthermore, the precipitation 
seems to be dependent upon the presence of atmospheric gasses.  
If argon is used to purge atmospheric gasses from the Tris Buffer 
and the solution is capped to prohibit gas transfer, precipitation 
does not occur.  Lanthanum is a common tool to study the transport 
of Ca2+.  I have read several references that use LaCl3 in Tris 
buffers at concentrations 1 to 2 orders of magnitude greater than 
the concentrations I am currently using with no mention of 
precipitation problems.  Does anyone have experience using 
LaCl3 in a Tris buffer?  Can anyone explain the precipitation 
and help me find a solution to this problem?  

Buffer Components:

	10mM	TrisHCl
	0.8mM	MgCl2
	1.0mM	CaCl2
	5.3mM	KCl
	140mM	NaCl
	0.1mM	LaCl3

	pH adjusted with NaOH to a final pH of 7.4


Thank you for any help.

Of course they do. There are all sorts of different things one can do 
comparing numbers. However, going back to the obscured to me Bovine 
Papillomavirus DNA binding domain, I'd like to ask one Q. 
Will our understanding of the biology of this virus change to _any_ extent 
should someone prove that affinity is 1 pM instead of 1 nM (or vice 
versa)? I bet - no. Sure, it'll make a lot of difference to people 
studying what combination of aa in what milieu works best when binding 
to a given structure, but for biology of the virus... Nowhere in the viral 
lifecycle we can apply those numbers to derive new and meaningful 
information about this organism. 

Thanks for reply, Tom. Intersting WEB site. I'll try to read the papers. I 
sure liked the idea of "No Consensus Sequences!" cause they make less and 
less sense as we go along the unknowns. .

Postscript # 64 to the "Lanzarote" paper (01/11/97)

                           "TIME"
                    By Peter Beamish Ph.D.

      Time has never been properly defined. It is the enigma of both 
modern physics and philosophy. 
     This reality now appears to be  partly because we need new 
definitions for "scalar and vector quantities" as well as the total 
number of  "dimensions" permissible in the universe in which we live.  
The latter is THREE orthogonal (at right angle) dimensions. It is 
impossible for the human mind to comprehend a fourth dimension that is at 
right angles to the other three! We can imagine four variables, in fact 
superstring theory requires ten variables, BUT THERE ARE ONLY THREE 
DIMENSIONS. The  mathematics of "n-variable" matrices is sound, useful 
and necessary for updating a theory combining general relativity and 
quantum mechanics, the so called quantum theory of gravity. But the 
n-variables must fit into three dimensions of space or, as I will soon 
suggest, into three dimensions of  "space-time." 
     A problem with defining time stems from an unclear definition of 
scalar and vector quantities. In classical physics texts a "scalar" has 
magnitude only, whereas a "vector" has both magnitude and direction. But 
direction is not the only property of space (as shown by Einstein). And, 
direction can be attained by simply adding a prerequisite to magnitude 
that it varies in the "direction" upward or say "forward" (1 to 10) or, 
downward or say "backward" (10 to 1 or -1 to -10). In fact it is the 
nature of time in its classical sense (time associated with the rotation 
of the Earth) that a measurement of its scalar property is always forward 
(with possibly very rare exceptions in studies of antimatter). This has 
been known as the "Arrow of Time," which becomes a vector if we add the 
new prerequisite above which thereby converts a scalar into a vector. But 
if the Arrow of Time is a newly defined vector then in what spacial 
direction or dimension does this arrow point? This is the clue that leads 
directly to "three dimensional time." Newtonian physics is missing two 
dimensions of time  and these dimensions by analogy to the three 
dimensions of space must be orthogonal to the Arrow of Time. 
     The western world mapped the rotation of the Earth onto the Arrow of 
Time by Euclidian geometry. But most of the remainder of the world, 
knowing little of this geometry more commonly used a different type of 
time, one based on cyclical, physiological properties (postscript # 30). 
Cycles are two dimensional, analogous to rotating wheels. And these 
cycles are often of a different period than that of the Earth. For 
example the timing of human breathing is obviously independent of the 
timing of the Earth's rotation. We have thus defined two types of time 
and both are vectors based on the above definition; they total to three 
dimensions which are necessarily at right angles. This is a coordinate 
system with a rotating wheel, always in the present, but  moving 
"forward" along the axis of classical time.  It can be superimposed onto 
the three space coordinates to form space-time in three dimensions. When 
this happens ten variables emerge to satisfy the superstring theories. 
There are three space variables or dimensions and seven time variables, 
three as dimensions and four as Rhythm Based Communication, "window" 
variables on the gauge symmetric wheel of the new "Rhythm Based Time" 
(diagram 2 in "Lanzarote" paper *). This circle can be of  any diameter 
so that it will satisfy the very small microphysics of quantum theory as 
well as the very large macrophysics of relativity and cosmology.


* The "Lanzarote" paper entitled "Rhythm Based Communication," published 
by the Secretariat of the World Conference on Sustainable Ecosystems, is

Cys2-His2 zinc fingers are on the order of 30 amino acids long. As the
name suggests, a zinc atom is critical for structural integrity of the
functional domain. Proteins which bind DNA via C2H2 zinc fingers do so
sequence specifically.  There's no evidence that single zinc fingers bind
nucleic acids, though. A minimum of three of these fingers are required to
bind or, as in the case of yeast ADR1, two fingers and a non-finger N
termial region.

C2H2 zinc fingers are everywhere (there are other kinds of zinc fingers as
well), so finding information about them should be easy. Mia Schmiedeskamp
and Rachel Klevit wrote a review of zinc fingers a few years back, which
is probably a good place to start.

And I'd like to bring up one of those other kinds of zinc fingers:
the Zn(2)Cys(6) binuclear cluster class, whose best known member is
the S. cerevisiae GAL4 transcriptional activator.  Somewhat similarly
to the Cys2-His2 group above, the part of the domain that binds DNA
and 2*Zn(II) is about 30aa in length and recognizes a 5'-CGG-3'
triplet.

This is somewhat of an oversimplification, though.  Similarly to the 
Cys2-His2 case, specificity is derived from using multiple domains;
in contrast, though, these domains are non-covalently dimerized, making
the spacing between two inverted CGG elements as the prime source
of specificity.  When you add the additional linker & dimerization
helix onto the DNA-binding domain, the total length kicks up to ca.
50-60aa.

References:
aside from my own work (NMR studies of GAL4 and LAC9, a K. lactis
GAL4 homologue :), I'd check into:

	*specificity: several recent papers by Aseem Ansari in 
		Mark Ptashne's group and references therein.

If you are so worried about immortality you better go to church.
My first inclination will be to strongly discourage people from wasting time
and resource in this endeavour. 
I do not see the use for it. Your body is a pretty safe place to conserve
DNA it would last long after you are burried and your offspring carried a
large portion of it.
On the other hand your DNA may contain incriminating information like
oncogene, the gene for alcohol addiction, homosexuality, race, stupidity
etc... While in your body your DNA is protected by the constitution. In a
test tube the DNA is up for grab.

This request brings up another issue that might be worth discussing. Should
these DNA binding regions be referred to as "domains" or "motifs"? In the
literature on protein structure the word "domain" usually refers to a
discrete, independently folding region with a globular structure. Such
domains consist of large stretches of primary sequence and they can be
recognized as distinct units in the overall structure of a protein. Domains
are usually connected by short linker sequences.

Domains, as defined by structural biologists, consist of multiple regions
of secondary or supersecondary structures. The supersecondary structures
are often referred to as "motifs". Examples of motifs include helix-loop-
helix regions, Greek keys, and beta-alpha-beta units. Some of these
supersecondary structures form the core of a DNA binding region and that's
why most textbooks refer to them as DNA binding "motifs". Examples are
the helix-turn-helix motif and the zinc finger motif. A counter-example
is the homeobox "domain"; a definition that is not consistent with the
terminology used by those who study protein structure.

It's not clear to me what MThompson is looking for. If it's really a
distinct "domain" then most of those who responded have not been helpful
since they have concentrated on "motifs". However, perhaps MThompson
really wanted an example of such a motif?

I realize that this might seem a bit picky but I think that it is important
to be consistent with terminology and I'm pleased to see that even leading
molecular biology textbooks have adopted the word "motif" to describe these
DNA binding regions of protein. This makes the biochemists happy.  (-:

Zinc fingers and other zinc containing structures are examples of motifs
and not, strictly speaking, domains. They are often part of a large domain
within a protein. Motifs are usually short stretches of primary sequence
on the order of 20-100 amino acid residues. Domains are larger.

Some people are very sensitive about the naming of zinc containing structures.
The C2H2 structure is called a zinc finger but the others are not referred
to as "fingers". It is probably useful to maintain this distinction.

Hi all:
	While my upstairs neightbor Larry (lamoran@gpu.utcc.utoronto.ca) 
brings up an interesting point in this discussion, I think we're on two 
different wavelengths on the definition of domains and motifs.  Anyone 
else care to comment?

OK --- looks good so far, although I don't agreed with the term "large

are as small as ~50-60 aa (SH3 domain, for example); if metals and/or
disulfide bonds are present, the size can be smaller.

Whoa --- speaking as a structural biologist who has worked on DNA-binding
domains such as these, I don't agree with this assessment.  The
Cys(2)His(2) canonical zinc finger and the GAL4/Cys(6) both fall into
a domain by your criteria that you initially listed: discrete,

to other domains by linker regions, and both have multiple regions of
secondary structure (2 strands of beta sheet and a helix for the
Cys(2)His(2), 2 helices for GAL4).  Yes, these domains require metal
ion(s) in order to assume their folded, active state.  

Given this above information, I'd be interested in hearing how these
would fail to be considered domains.  Yes, they are small domains 
(as asked for), but I believe they meet the appropriate criteria.

Being one of those people who's worked on the naming of zinc-containing
structures that isn't a Cys(2)His(2) domain, I'd like to see this
distinction maintained.  But I also realized that the chances of this
happening are essentially nil....

I readily admit that the literature is confusing on this issue and many
workers refer to helix-turn-helix "domains" and zinc finger "domains".
The purpose of my posting was to point out that the protein structure
experts often refer to these as "motifs" because the word "domain" has
a different meaning. You will notice in the more recent literature and
in textbooks that the word "motif" is gaining in popularity - rightly
so in my opinion. (see the titles of Lee et al. (1989), Berg (1990), 
and Chan et al. (1993)).

In Coleman's review of zinc proteins from 1992 he refers to zinc finger
motifs in some cases but to domains in other cases so even five years
ago there was some confusion in the literature.

Let's see what Creighton has to say in his textbook. In chapter 8 he talks
about DNA binding proteins and the various binding motifs including the
zinc finger motif (p.358). He doesn't refer to these regions as domains
because he defines domains quite differently,

     "The folded structures of most small proteins are roughly 
      spherical and remarkably compact, with very irregular surfaces.
      The structures of most proteins that have more than about 200
      residues appear to consist of two, three, or more structural 
      units, usually referred to as domains. The domains of a protein
      molecule interact to varying degrees, but less extensively than
      do structural elements within domains. Often a single segment of
      a polypeptide chain links the domains, and each domain consists
      of a single stretch of polypeptide chain. ... The definition of
      a domain is not rigorous, and the division of a structure into
      domains is a subjective process that is done in different ways 
      by different people. Other terms and subdivisions, such as
      subdomain and folding unit, are also encountered in the literature.
      Nevertheless, the presence of domains in many protein molecules
      is clear to all observers (Figures). Domains are most evident
      by their compactness, which can be expressed quantitatively as 
      the ratio of the surface area of a domain to the surface area
      of a sphere with the same volume ..."

                                            Creighton (1993) p.219

As a general rule of thumb you should be able to recognize domains in a
space-filling model of a protein. They form separate "blobs" that are
quite obvious. If you can't pick out a specific region easily by looking
at the gross morphology of the protein then it isn't a domain by Creighton's
definition.

Zinc fingers are not domains by this definition. A typical zinc finger
contains three regions of secondary structure (two beta regions and an
alpha helix). This is typical of many other supersecondary structures
or motifs that have been recognized in proteins (ie: beta-alpha-beta units).
There doesn't seem to be any convincing reason to call a zinc finger
a domain but not other types of supersecondary structure. And there
doesn't seem to be any logical reason to degrade the term "domain" when
we have a perfectly good alternative in "motif".

Haven't read the whole discussion - sorry if this point has been made.
The distinction between domains and motifs is not related to size, or
number
of residues etc. There is no physical size limit on a motif, it can be
as
small or as large as you want.  There are, however, upper and lower
physical size limits on domains (would be quite interesting to discuss
the possible reasons for this, but it's a bit off-topic, so I won't)

A motif is a feature that is commonly recurring.  So a Zinc finger could
be
called a motif.  But I don't see why it couldn't also be called a
domain.  A
good definition of a protein domain is tricky - but something in terms
of a
strong (maybe or maybe not autonomous?) intrinsic propensity to fold to
it's 
native form is a good way to think about it.

Gotta go,

Simon

need to process many samples with great rapidity and so organic extraction =
and HPLC etc =

stellar objects) of =

a reference sample could be compared to an unknown and additional absorptio=

subtracted to help identify the possible contaminant by comparison to a dat=

potential contaminating substances (or mixtures). Like I said, I'm not very=

the techniques that might be employed or the equipment. So, would I need a =

 And can anyone =

with more experience give me an idea if this might work?

Thanks for any suggestions,

Check out the T4 endonuclease V; it's a DNA-repair enzyme, preparing
thymine-dimers for the complete excision by the DNA polymerase. 
I worked on this enzyme about 7 - 8 years ago, when I was a post-doc in
Japan. 
Unfortunately, it is nothing really known about the binding site, but
assuming the longest axis of this small protein (~16kDa) is equivalent
to the maximal number of basepairs that can bind, the number should be
<= 8 pairs.

We were never sure about the binding-site, because several of the really
important site-directed mutants were not expressed by E. coli. However,
there is a very good crystal structure available.

The institute's name was 'Protein Engineering Research Institute
(PERI)', but has now be changed to  BERI. They have a web-page:
http://www.beri.co.jp/

Look for papers with the names of Morikawa, Tomoko Doi and myself. There
was also a competitors group in the US, but I forgot the name of the
groupleader.

Pittsburgh Supercomputing Center
                   Supercomputing Techniques:  CRAY J90/C90 
                               March 24-27, 1997

--------------------------------------------------------------------------------
                 REGISTRATION DEADLINE:  March 3, 1997
--------------------------------------------------------------------------------

PURPOSE:

        The purpose of this three and a half day workshop is to
introduce 
        participants to computing on the CRAY J90/C90. Participants will
gain 
        experience in running jobs on the J90/C90, optimizing code,
parallel 
        processing, and on the use of graphics software libraries and
packages.

AGENDA:

        The first day of this workshop is designed to introduce
participants 
        to the J90/C90 platform.  During this time, participants will
become 
        familiar with PSC's supercomputing environment, the UNICOS
operating 
        system, CRAY compiling, job submission, troubleshooting, and
debugging.

        The last three days of this workshop are designed for users who
are 
        already familiar with running jobs on the CRAY J90/C90 and who
are 
        interested in more advanced topics:

        * The Code Optimization portion will cover performance
monitoring 
          techniques and strategies to improve the performance of one's
code. 

        * The Parallel Processing portion concentrates on the mechanics
of 
          parallel computing on the J90/C90 systems.  

        * The final day will explore graphics and visualization topics
ranging 
          from a general overview of graphics packages available at PSC
to a 
          more advanced discussion of animation and 3-D graphics.  

        To ensure that participants receive quality training, our
workshops
        incorporate both lectures and extensive hands-on lab sessions. 
        Programming exercises are carefully designed to reinforce
concepts and 
        techniques taught in class. Our instructors have strong
scientific and
        technical backgrounds and are available for individual
consultation 
        during lab sessions.

        In addition to the lab exercises, lab time will also be
available for 
        participants to optimize their own code with the help and
        supervision of our instructors.  Participants are encouraged to
bring
        their code, but not required. 

        ==> A working knowledge of FORTRAN or C and UNIX are required.

REGISTRATION FEES:

        Admission to this training workshop is free to the United States
        academic community. 

        Interested corporate and government applicants, as well as
applicants
        from academic institutions outside the United States should

This BIOSCI "miniFAQ" is designed to answer the questions that come up
the *most frequently*.  The main BIOSCI FAQ (Frequently Asked
Questions) is accessible on the World Wide Web at URL
http://www.bio.net/.

If you can not find an answer to your question in this or other
documentation, the BIOSCI technical support staff answers e-mail
queries sent to

		       biosci-help@net.bio.net

We can only answer questions about the use of the newsgroups and
mailing lists.  We unfortunately do not have the staff to do Internet
information searches or answer scientific questions.  Please post
those to the appropriate BIOSCI/bionet newsgroups.

0) BIOSCI NEEDS YOUR SUPPORT!!
------------------------------
BIOSCI's government funding has been expended, and we are now
operating solely from advertising revenue that we have raised from our
Web site at http://www.bio.net/.  We need just a few minutes of your
time to help us serve you.

You can do two important things which will take very little time for
you individually and will immensely help us continue to help you.

First, please use our WWW system at http://www.bio.net/ to access the
archives.  You can post or reply to messages via your Web browser as
described in item #1 below.  Your usage helps attract sponsors. If you
contact any of our sponsors, please be sure to thank them for
supporting BIOSCI. It is critical for them to get this feedback if
they are to continue their sponsorship for the long term.

Second, if you work for a company or organization that provides
products or services of interest to the biology community, please pass
this message on to your marketing or marketing communications
department or other appropriate group.  Please ask them to help
support BIOSCI by sponsoring our Web site and explain the uses and
benefits of the system to the biology community. If they are
interested, they can then contact us for further information at our
tech support address, biosci-help@net.bio.net.


1) Using the WWW to access the BIOSCI/bionet newsgroups.
--------------------------------------------------------
As of 10 December 1995, all BIOSCI/bionet full newsgroups are
accessible through the World Wide Web (WWW) at URL http://www.bio.net.
One can read and reply publicly or privately to both recent postings
and archived messages through one's Web browser if it is configured
properly to send e-mail.  Each newsgroup is equipped with its own WAIS
index.  The main BIOSCI home page also has access to the BIO-JOURNALS
Table of Contents database WAIS index and the BIOSCI user address
database described in another item further below.


2) What to do about "spams," i.e., junk mail, ads, etc.
-------------------------------------------------------
BIOSCI is a set of parallel USENET newsgroups (the "bionet" groups),
mailing lists, and a hypermail archive at URL http://www.bio.net/.
The same postings are distributed on all media (except for a small
number of mailing-list-only groups at net.bio.net).  Unfortunately it
is becoming a despicable practice on the Internet (by a few people out
to make a fast buck) to do automated mass postings to thousands of
newsgroups and mailing lists.  These attempts to grab free advertising
are refered to as "spams" in the usual, somewhat boneheaded, net
terminology.  USENET is more susceptible to this practice, and many
spams originate on the USENET groups and then are passed on to the
mailing lists.  However, spammers also get lists of mailing addresses
and hit these too, so neither medium is immune.

What should you do personally if you get junk mail?
---------------------------------------------------
Just delete it and move on without reading it further.  Filing a
protest is becoming increasingly useless because spammers are often
disguising the addresses where the messages are sent from.  Unless you
really understand Internet mail systems, your attempt at protest by
sending replies to the message will often end up being sent to the
address of an innocent person that the spammer is victimizing.

What can BIOSCI/bionet do to protect its newsgroups?
----------------------------------------------------
The only solution currently available is to moderate the newsgroup.
If this newsgroup is already moderated, then you are in good shape.
Moderation protects the USENET distribution from about 95% of the
spams that are being sent to date and protects the mailing lists
completely.  Moderation means, however, that someone has to take the
time to review each message before it goes out.  We have set up
software here that simply allows the moderator to forward to an
address at net.bio.net messages that (s)he wishes to have distributed.
This takes no more time than that needed to read the message and pass
it on, say about 1 min. per message.

Most newsgroups currently have a discussion leader who is responsible
for their newsgroup.  The discussions leaders and their e-mail
addresses are listed in the BIOSCI Information Sheet which is
available on the Web at http://www.bio.net/.  If a newsgroup is being
hit with too many junk postings, please contact the discussion leader
for that group and see if there is interest in moderating the group.
Please do not assume that by simply posting a complaint to the
newsgroup itself, anyone on the BIOSCI staff will act on your
complaint.  With close to 100 newsgroups to run, the BIOSCI staff has
to rely on the discussion leaders of each newsgroup to report problems
directly to us at biosci-help@net.bio.net.

We will moderate any of our newsgroups if the discussion leader tells
us that the readership of the group wishes to do so and if a moderator
is willing to do the work.  For most BIOSCI/bionet groups, this
entails only a few minutes of work each day.

Moderating a newsgroup will resolve probably 95% of the junk postings
on the USENET distribution.  Unfortunately there are easy ways for
determined spammers to override the moderation mechanism on USENET,
but we can protect our e-mail subscribers from unwanted postings if
the newsgroup is moderated.  You can also access our newsgroups over
the WWW at URL http://www.bio.net.  While this Web interface will not
stop spammers from trying to post to the groups, this will give you
yet another way, besides using USENET news, to keep the junk out of
your personal mail files.  For those of you with local USENET news
systems, the Web interface will also give you faster access to new
newsgroups and recent postings.


3) Examples of subscribing and unsubscribing to the mailing lists.
------------------------------------------------------------------
PLEASE NOTE: The BIOSCI management does NOT act on
subscription/unsubscription requests that are posted improperly to the
newsgroups and mailing lists.  People who do this only bother everyone
on the lists to no avail.  Please be sure to follow the proper
procedures below.

Gory details are in the BIOSCI Information sheets on the Web at
http://www.bio.net.  Below we give an example utilizing the
METHODS-AND-REAGENTS list at both of our two BIOSCI sites:

Users in the Americas and Pacific Rim countries who use the BIOSCI
------------------------------------------------------------------
node at computer net.bio.net:
----------------------------

A) Determine the "listname" which is the <=8 character mail address
                                         ^^^^^^^^^^^^^
   for the group.  These can be found in the BIOSCI Info. Sheet.  For
   the METHODS-AND-REAGENTS group the mailing address is
   methods@net.bio.net.  The listname is the portion of the address to
   the left of the @ sign, i.e., "methods".  The listname is used with
   the "subscribe" and "unsubscribe" commands illustrated below.

B) Mail all commands in the body of a mail message addressed to
   biosci-server@net.bio.net.  Do NOT send commands to the newsgroup
   posting addresses!  Leave the Subject: line blank, any text on it
   will be ignored.

C) In the body of your message put one or more of the following
   commands with an "end" command on the last line, e.g.,

   subscribe methods
   unsubscribe methods
   end

   Do NOT put your e-mail address or other text on these lines.  The
   server only allows you to cancel your subscription if the address
   on your mail header matches the address on our mailing list.
   Please ask for help at biosci-help@net.bio.net if your address has
   changed, e.g., if you know you are on the list but the server tells
   you that you are not a member.


Users in Europe, Africa, and Central Asia who use the BIOSCI node at
--------------------------------------------------------------------
computer daresbury.ac.uk (also known as dl.ac.uk):
-------------------------------------------------

To subscribe and unsubscribe to/from the BIOSCI lists, you need to
specify the full USENET newsgroup name with "bionet-news." prepended.
The USENET newsgroup names are listed in the BIOSCI Information sheet
on the Web at http://www.bio.net/.  For the METHODS-AND-REAGENTS list
the USENET newsgroup name is bionet.molbio.methds-reagnts, thus the
appropriate commands are

    sub bionet-news.bionet.molbio.methds-reagnts

    unsub bionet-news.bionet.molbio.methds-reagnts

These commands are included in a message addressed to mxt@dl.ac.uk,
NOT to the newsgroup mailing addresses.  As usual, include the text in
the body of the message as text on the Subject: line is ignored.

To unsubscribe from all the lists at the UK node, use

    unsub bionet-news

Please note that if the address in the list is different than the one
in your mail message header, you will not be able to unsubscribe by
this method. If you have problems, please mail biosci@daresbury.ac.uk.


4) The BIOSCI user address and research interest directory.
-----------------------------------------------------------
Please take this opportunity to add your name, address, and research
interest information to the BIOSCI User Address Database if you have
not already done so.

You can fill out the address form directly through our Web page at URL
http://www.bio.net/adrform.html.

The address database is reindexed nightly for WWW access (the URL is
http://www.bio.net/).  If you are not directly on the Internet but can
reach it by e-mail, please use our waismail server to access the user
directory.  waismail use is described above.  You can also request a
user address form by e-mail from biosci-help@net.bio.net.
