Some fragments out of a review I am writing: The earliest starvation induced promoters are termed the "prestarvation response" (Clarke et al., 1987, 1988) and are controlled by both the cells nutritional status and an extracellular "prestarvation factor" (PSF). PSF is an autocrine signal secreted by growing cells that accumulates in the medium in proportion to cell density (Rathi et al., 1991; Rathi and Clarke, 1992). Cells grown on bacteria only respond to PSF when the bacteria become depleted, inducing the prestarvation genes about three generations before the cells cease logarithmic growth (Clarke et al., 1987). PSF also induces the production of a range of proteins required for the early stages of multicellular development, eg contact sites B EDTA sensitive adhesion protein (Rathi and Clarke, 1992). PSF is produced by growing cells and production decreases in starvation to low lvevels by 4 hours. Thus, PSF will be in excess under the high cell concentrations (>5x106) used for the production of recombinant proteins unless the starving cells are washed. PSF is a heat labile, non-dialysable glycoprotein protein which binds to the lectin ConA (Rathi and Clarke, 1992). Note that the PSF does not inhibit cell growth (Clarke et al. 1988). However, stationary phase cells produce other factors which if added to log phase cells will block cell division and depress the rate of transcription, but which do not affect transcription in stationary phase cells (Yarger et al., 1974; Yarger and Soll, 1975; Soll et al., 1976; Ferguson and Soll, 1976). These growth inhibitory factors provide an explanation of why most D. discoideum cultures stop growing at around 1-2x107 cells per ml in the presence of excess nutrients, but their effects on the transcription of prestarvation genes is unclear. Axenically grown, stationary phase cells (1x107/ml) no longer express the prestarvation gene discoidin I (Devine et al, 1982). Expression of developmentally regulated genes requires a second cell density sensing signal "conditioned medium factor" (CMF) which is different to PSF described above (Clarke et al., 1992), although CMF also causes elevated expression of discoidin I in starving cells (Gomer et al., 1991). CMF's function is to ensure that multicellular development only occurs above a threshold cell density. CSF is slowly secreted by starving cells and the extracellular levels signals the cell density. Although CSF does not appear to be secreted by growing cells (Gomer et al., 1991), it is present in internal vesicles (Yuen et al., 1991). The receptor for CMF is virtually absent from growing cells and is maximally expressed in cells starved for 6-8 hours (Jain and Gomer, 1994). CMF is an 80 kDa protease sensitive glycoprotein (Gomer et al, 1991; Jain et al., 1992), but after 10 hours of starvation, proteolytic break down of CMF produces 0.5-6.5 kDa glycopeptides which are 100 fold more active than the intact molecule (Yuan et al., 1991).

The smallest sqaures in the counting chamber measure 50 micrometers (um) or 0.05 mm. By loading a paramecia culture into the slide/coverslip assembly and using the stopwatch, you and a partner can record when an organism crosses the 50 um line. Then you can convert that distance to mph or meters/sec by referring to the appropriate conversion table (um to meters, meters to feet or yards, feet or yards to miles, etc). Then see how fast the organisms move in Protoslo, available from any teaching supplier like Carolina Biologicals, Sargent Welch or Wards.

The main BIOSCI FAQ (Frequently Asked Questions) is accessible on the World Wide Web at URL http://www.bio.net/. Contents: -------- 1) Using the WWW to access the BIOSCI/bionet newsgroups. 2) What to do about "spams," i.e., junk mail, ads, etc. 3) Examples of subscribing and unsubscribing to the mailing lists. 4) The BIOSCI user address and research interest directory. 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 in addition to the master index for the entire set. 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.

I have a lab, I teach in Zoology where we use Paramecium and some other ciliates (wild varieties I have gathered). The methods suggested by the lab manual just do not work that reliably. They suggest both fountain pen ink and acetic acid. Acetic acid seems to work better but neither works that often. I add solution to the side of the coverslip and then draw it under using a bit of paper toweling on the other side. The problem is either it doesn't do anything or the duds croak with out obviously firing. I realize it may be a concentration problem but I would like to have something that can be drawn under the coverslip so the students can see it. When it happens it is dramatic. Any suggestions? -- : James F.

I have a lab, I teach in Zoology where we use >Paramecium and some other ciliates there are 3 (at least) quite different possibilities : 1. the "natural" or physiological way will use the attack of predators like Dileptus to induce localized trichocyst extrusion; for details see: - Harumoto T, Miyake A (1991) Defensive function of trichocysts in Paramecium.

I. A novel approach. Exp Cell Res 151:6-13 3. a potent chemical inducing extrusion and simultaneous fixation is picric acid, being in use for rather long times as sectretagogue in this system; for a quite recent reference see e.g.: - Satir BH (1989) Signal transduction events associated with exocytosis in ciliates.

We work on one such foraminiferal assemblage in Explorers Cove, McMurdo Sound, Antarctica. These "giant" protists are increasingly thought to play an important role in benthic nutrient cycling, and some of the ones we work on are predators of small invertebrates and the juveniles of larger inverts. This raises the possibility that predation pressure by these protists may structure benthic communities. (Hopefully this idea can be te$ted given $ufficient grant funding). Since the deep sea is Earth's most extensive habitat, the larger agglutinated forams might turn out to be among the most abundant/important organisms on the planet -- protist or otherwise. (Excluding humans, of course.) If you need further information I'd be happy to supply some references or some images of our Antarctic beasts.
