    Description: Spirochetes believed to be the cause of Lyme disease were isolated from white-footed mice and white-tailed deer, the preferred natural hosts of Ixodes dammini, the tick vector. Evidence suggests that deer act as a reservoir of the disease and provide an overwintering mechanism for both spirochetes and adult ticks. Some tick larvae may acquire the spirochete by transovarial passage and the nymphal stage may transmit the disease to humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bosler, E M -- Coleman, J L -- Benach, J L -- Massey, D A -- Hanrahan, J P -- Burgdorfer, W -- Barbour, A G -- New York, N.Y. -- Science. 1983 Apr 15;220(4594):321-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836274" target="_blank"〉PubMed〈/a〉

    Description: Animals with a history of receiving daily injections of +-amphetamine in a specific environment showed a placebo effect (enhanced activity) when injected with saline and placed there; control animals with similar but dissociated drug histories and experience with the test chamber failed to show the effect. The dopamine receptor blocker pimozide antagonized the establishment of conditioning. However, the same dose of pimozide, when given to previously conditioned animals on the placebo test day, failed to antagonize the expression of conditioned activity. Thus, during conditioning dopaminergic neurons mediated a change that subsequently influenced behavior even when dopaminergic systems were blocked. Although schizophrenia may be related to hyperfunctioning of dopamine, neuroleptic drugs, which block dopamine receptors on their first administration, do not have therapeutic effects for a number of days. The results of the pimozide experiments may resolve this paradox.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Beninger, R J -- Hahn, B L -- New York, N.Y. -- Science. 1983 Jun 17;220(4603):1304-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6857251" target="_blank"〉PubMed〈/a〉

    Description: Oral administration of 13-cis-retinoic acid (40 or 160 milligrams per kilogram of body weight daily) significantly reduced the inflammation associated with developing and established adjuvant arthritis, an experimentally induced arthritis in rats that resembles human rheumatoid arthritis. The amount of collagenase secreted in tissue culture by adherent cells isolated from the inflamed joints of adjuvant rats treated with 13-cis-retinoic acid also decreased as compared to the amount secreted by cells from vehicle-treated adjuvant rats. Collagenase is important in the joint destruction accompanying rheumatoid arthritis. The successful use of retinoids in the treatment of this proliferative but nonmalignant disorder demonstrates a new application of these compounds.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brinckerhoff, C E -- Coffey, J W -- Sullivan, A C -- AM14780/AM/NIADDK NIH HHS/ -- P60 AM20641/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1983 Aug 19;221(4612):756-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6308759" target="_blank"〉PubMed〈/a〉

    Description: Extracellular single-unit recording techniques were used to test the ability of proglumide to block cholecystokinin-induced excitation of rat midbrain dopaminergic neurons and dopamine-sensitive prefrontal cortex cells. Intravenous and iontophoretic proglumide administration consistently blocked cholecystokinin-induced excitations while having no effect on glutamic acid-induced increases in activity. This selective blockade of central cholecystokinin effects by proglumide suggests that this drug may be valuable for studying the possible role of cholecystokinin as a neurotransmitter or neuromodulator in the central nervous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chiodo, L A -- Bunney, B S -- MH-25642/MH/NIMH NIH HHS/ -- MH-28849/MH/NIMH NIH HHS/ -- NS-07136/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1983 Mar 25;219(4591):1449-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6828873" target="_blank"〉PubMed〈/a〉

    Description: Brief deprivation of vision after unilateral lesions of the frontal eye field prevents the appearance of contralateral inattention to visual, auditory, and somatosensory stimuli. The forced circling that accompanies inattention, however, is not affected. An equivalent preoperative period in the dark only partly reduces inattention symptoms. Visual deprivation does not reduce or prevent inattention resulting from lesions of the superior colliculus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crowne, D P -- Richardson, C M -- Ward, G -- New York, N.Y. -- Science. 1983 Apr 29;220(4596):527-30.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836298" target="_blank"〉PubMed〈/a〉

    Description: Microvoltammetric electrodes were used to monitor dopamine released in the caudate nucleus of the rat after electrical stimulation of the medial forebrain bundle. The time resolution of the technique is sufficient to determine in vivo concentration changes on a time scale of seconds. Direct evidence identifying the substance released as dopamine was obtained both voltammetrically and pharmacologically. Administration of alpha-methyl-p-tyrosine terminates the release of dopamine, although tissue stores of dopamine are still present. Thus there appears to be a compartment for dopamine storage that is not available for immediate release. This compartment appears to be mobilized by amfonelic acid, since administration of this agent after alpha-methyl-p-tyrosine returns the concentration of dopamine released by electrical stimulation to 75 percent of the original amount.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ewing, A G -- Bigelow, J C -- Wightman, R M -- KO 4 NS000356/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1983 Jul 8;221(4606):169-71.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6857277" target="_blank"〉PubMed〈/a〉

    Description: The acquired immune deficiency syndrome (AIDS), which has recently occurred at increasing rates in homosexual men, intravenous drug users, and others, is characterized by the development of Kaposi's sarcoma and several opportunistic infections including pneumonia caused by Pneumocystis carinii. Serum samples from patients with AIDS and from matched and unmatched control subjects were examined for the presence of antibodies to cell membrane antigens associated with human T-cell leukemia virus. Nineteen of 75 of the AIDS patients had antibodies directed to surface antigens of Hut 102, a reference T lymphoid cell line infected with leukemia virus, as did two of the 336 control subjects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Essex, M -- McLane, M F -- Lee, T H -- Falk, L -- Howe, C W -- Mullins, J I -- Cabradilla, C -- Francis, D P -- 2T32CA09031/CA/NCI NIH HHS/ -- 5T32HL07523/HL/NHLBI NIH HHS/ -- CA 18216/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1983 May 20;220(4599):859-62.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6342136" target="_blank"〉PubMed〈/a〉

    Description: Infective third-stage larvae of Dipetalonema viteae (Nematoda: Filarioidea) were cultured to young adults in a cell-free culture system. Third-stage larvae from the tick vector grew, developed, and molted twice in a medium containing NCTC 135 and Iscove's modified Dulbecco's medium supplemented with fetal bovine serum under a gas phase of 95 percent nitrogen and 5 percent carbon dioxide. The availability of such a culture system for filariids should facilitate studies of their immunology, biochemistry, and sensitivity to drugs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Franke, E D -- Weinstein, P P -- AI 07030/AI/NIAID NIH HHS/ -- AI 09625/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1983 Jul 8;221(4606):161-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6682998" target="_blank"〉PubMed〈/a〉

    Description: Markedly elevated nighttime concentrations of serotonin in rhesus monkey cerebrospinal fluid were reduced to daytime levels by exposing the monkeys to continuous light or to the beta-adrenergic antagonist propranolol. Nighttime elevations of melatonin in cerebrospinal fluid were also suppressed by propranolol and light. Serotonin released in large quantities at night appears to be regulated like melatonin, and may act as a cerebroventricular hormone to influence brain and pituitary function at night.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Garrick, N A -- Tamarkin, L -- Taylor, P L -- Markey, S P -- Murphy, D L -- New York, N.Y. -- Science. 1983 Jul 29;221(4609):474-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6683428" target="_blank"〉PubMed〈/a〉

    Description: The acquired immune deficiency syndrome (AIDS) is characterized by T-lymphocyte dysfunction and is frequently accompanied by opportunistic infections and Kaposi's sarcoma. Human T-cell leukemia virus (HTLV) is associated with T-cell malignancies and can transform T lymphocytes in vitro. In an attempt to find evidence of HTLV infection in patients with AIDS, DNA from samples of peripheral blood lymphocytes from 33 AIDS patients was analyzed by Southern blot-hybridization with a radiolabeled cloned HTLV DNA probe. Analysis of DNA from both the fresh (uncultured) lymphocytes and from T cells cultured with T-cell growth factor revealed the presence of integrated HTLV proviral sequences in lymphocytes from two of the patients, both of whom had antibody to HTLV. The proviral sequences could not be detected in blood samples obtained from these individuals at a later date, consistent with the possibility that the population of infected cells had become depleted.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gelmann, E P -- Popovic, M -- Blayney, D -- Masur, H -- Sidhu, G -- Stahl, R E -- Gallo, R C -- New York, N.Y. -- Science. 1983 May 20;220(4599):862-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6601822" target="_blank"〉PubMed〈/a〉
