Achievements A taekwondo centre has been established, as well as workshops held in swimming, tennis, volleyball and football. A proper sports orientation was held for UG and PG freshmen unlike in previous years when it was clubbed with orientations of other activities. Screening of the football World Cup. Inter-IIT 1. Part-time coaches have been appointed to train some teams before Inter-IIT - badminton, weightlifting and swimming. 2. The daily allowance during Inter-IIT has been increased from Rs.110 to Rs.150. 3. The cost of messing per day during Inter-IIT borne by the institute, for all members attending Inter-IIT camp ; has been increased from Rs.110 to Rs.130 in the hope that quality of food will increase. Shortcomings Sponsors for Inter-IIT track suits could not be acquired though mentioned in the manifesto. Basic tasks such as updating the sports section of the gymkhana website have not been completed. Manifesto-related issues An issue that irks us at InsIghT is the bloating up of manifestos. The manifestos of all the GS Sports candidates looked similar last year with many promises of unachievable goals. Kuppa's manifesto had points such as the organisation of a Sports Festival, restructuring of NSO and formation of a Sports Club. It is high time the GSs showed some accountability with respect to what is proposed in their manifestos. Other issues.
14 A recent study using isolated rabbit sino-atrial node cells indicate that ICa, L contributes to the pacemaker diastolic depolarisation 25 ; . It has been established that ICa, L is also present in murine sino-atrial node myocytes 2 ; . Furthermore, knockout mice deficient in the voltage-gated L-type Ca2 + channels exhibit a bradycardia in vivo relative to their wild type controls 21 ; . Similarly, in this present study, partial inhibition of ICa, L with a low concentration of nifedipine 200nM ; reduced the beating rate of the spontaneously beating mouse atria. Therefore, modulation of ICa, L by autonomic neurotransmitters could alter heart rate in the mouse
The range we explored here goes from projected linear size 20 h-1 pc limit of our selection ; down to a few tenths of kpc, corresponding to our resolution limit. Sizes are evenly distributed in power, but we do not expect to see any trend, given the small explored size range. The shape of the LLS distribution function, is instead an important tool to study the evolution of powerful radio sources in the youth scenario see Fanti et al. 1995; Readhead et al. 1996; O'Dea & Baum 1997; Fanti 2000 ; . In our sample this function can be fitted pretty well by the power law dN LLS ; LLS ; -m d LLS ; with m 0.6 0.1.
Issues; an assessment of preclinical data needs for human immunogenicity of large molecules; an appreciation of clinical immunotoxicology--liabilities and `bridges' between nonclinical and clinical approaches; and an update on the progress of creating a nonhuman primate immunotoxicology database. The success of the HESI ITC is based on an approach where international experts from academia, industry and government come together in a neutral forum and a cooperative atmosphere to engage in an open and transparent exchange of scientific ideas. P7-11 NOVEL STRATEGY FOR CLASSIFYING DERMAL SENSITIZING POTENCY OF CHEMICALS WITH NON-RADIOISOTOPIC MODIFICATION OF LOCAL LYMPH NODE ASSAY M. Takeyoshi, K. Iida, K. Shiraishi, S. Hoshuyama Hita Laboratory, Chemicals Evaluation and Research Institute, Japan The murine local lymph node assay LLNA ; is currently recognized as a stand-alone test method for determining the sensitizing potential of chemicals. It has an advantage to give quantitative endpoint that can be used for predicting the sensitization potency of chemicals. For this purpose, EC3 value has been proposed as a parameter for classifying the chemicals according to the sensitization potency. We have previously developed a non-radioisotopic endpoint for the LLNA using 5-bromo-2 -deoxyuridine BrdU ; incorporation Non-RI LLNA ; . We propose here a novel strategy to predict the sensitization potency of chemicals by relative comparison with known human contact allergens. Nine chemicals categorized from class 1 to class 5 human contact allergen, diphencyclopropenone, p-phenylenediamine, glutaraldehyde, cinnamicaldehyde, citral, eugenol, isopropyl myristate, propyleneglycol, hexane, were tested by the non-RI LLNA with the reference allergens, 2, 4dinitrochlorobenzene DNCB ; as the class 1 human contact allergen, isoeugenol as the class 2 human contact allergen and -hexylcinnamicaldehyde HCA ; as the class 3 human contact allergen. Consequently nine.

Results Figure 2 illustrates a dotplot of murine sperm a typical control ; with FITC-tagged BrdU green peak ; and sperm without BrdU red peak ; . For validating the LSC-based method, a series of control experiments were performed. As shown in Table I, the highest variability was observed between a cohort of five animals 36.8 12.3 ; . Variability between five slides from one animal was somewhat lower 33.7 3.8 ; and even lower between different scoring areas on a single slide 28.4 3.2 ; . These findings indicate that interindividual variability rather than scoring variability is responsible for the large standard deviations of the results in these experiments. Figure 3 shows the comparison between the two control groups. No significant difference can be observed. The frequencies of BrdU-labelled sperm form a plateau between 21 and 23 days confirming the original choice of the sperm-sampling time of 22 days after treatment in the sperm-FISH assay. Of the nine chemicals tested in the BrdU assay, seven did not cause significant changes in the duration of the meiotic divisions in mouse spermatocytes Tables II and III ; . With DZ, a non-significant peak of BrdU-labelled sperm occurred on day 21; however, the results of the other days were in the control range Table II ; . With GF and VBL, the frequencies of BrdU-labelled sperm on days 22 to 24 were lower than in the concurrent control groups, but the difference was not 341 and mycostatin.

Consisting of 1, 2-diamino-cyclohexane and operable isomers thereof in the form of a dihydrohalide with alkali metal or hydrogen hexachloro-platinate. New substantially isomerically pure tetrahalo 1, 2-diaminocyclohexane ; Pt IV ; complexes having antineo-plastic activity were disclosed [221]. Novel 1, 4 and 1, 2-diaminocyclohexane platinum IV complexes have been synthesized that show activity in vivo against tumor models resistant to cisplatin and tetraplatin [222]. The novel complexes include the chloro, acetate, trifluoroacetate, propionate, butyrate, pentanoate, hexanoate and heptanoate as leaving ligands and 1, 4 or 1, 2-DACHamine ligands. The complexes showed good in vitro cytotoxic activity against murine leukemia L1210 0, L1210 DDP and L1210 DACH. High in vivo activity was shown against L1210 leukemia cells and against cisplatin resistant L1210 DDP. Excellent antitumor activity against M5076 was also exhibited by the new complexes. Additionally, the platinum complexes did not elicit any indication of nephrotoxicity in the in vivo tests. CURRENT AND FUTURE DEVELOPMENTS Coordination chemistry in living systems is more than just a matter of metal-ligand bond formation and metalligand stability. Control of metal binding to DNA, by simultaneous coordination and hydrogen bonding has been crucial to research. It needs no discussion that the abovepresented highlights and outlook provide fascinating new possibilities for research in the coming decade. New techniques, which follow the reactions of Pt complexes and nucleic acids and proteins, will allow the detection of otherwise invisible intermediate products. In summary, it is generally appreciated that enormous progress has been made in the understanding of the mode of action of cisplatin. Application of this knowledge in drug design is close, and it is generally expected that in the next decade improved antitumor drugs will be developed based on the knowledge of the Pt-DNA interactions and their repair ; and on the kinetics of binding of Pt compounds to proteins and DNA. Although questions have been raised about whether the intrinsically weak metal-ligand coordination bond will ever lead to new drug applications, the kinetic control of stability is likely to overcome this. The need for new platinum antitumor drugs was underscored by the usefulness of cisplatin and carboplatin in chemotherapy and the resistance of many tumors to these compounds. Combinatorial chemistry could aid in the search for cisplatin analogs if fast, high-throughput assays were available. The goal is to develop rapid cell-based assays suitable for high-throughput screening that accurately predicts the cytotoxicity of platinum complexes. The next stage in drug design is likely to be the development of dedicated drugs that comprise the transport through the membranes ; , survival in the cell, binding to the DNA, and eventually, excretion from the body with minimum side effects. In this process, both metal coordination and hydrogen bonding will be key factors at the molecular level. CONCLUSION Recent advances in medicinal inorganic chemistry demonstrate significant prospects for the utilization of metal.

Pregnancy is normally associated with changes in the coagulation system. These include accelerated platelet activation and increased platelet turnover, as well as an increase in the plasma concentration of clotting factors, including factors I brinogen ; , V, VII, VIII, IX, X and XII. As an example, factor VIII levels normally increase by 200 500% late in pregnancy.1 There is also enhanced brinolysis with increased thrombin production. This state of accelerated but compensated intravascular coagulation serves as a protective mechanism to curb maternal blood loss during delivery. On occasion, labour analgesia in the form of neuraxial block is provided to patients with haematological disorders. Coagulation factor deciencies and thrombocytopenia can increase both anaesthetic and obstetric risks. Performing neuraxial block in patients with these disorders risks the development of an epidural haematoma, a potentially catastrophic complication that can lead to permanent paralysis and nadolol
Carefully controlled experiments using the guinea pig model of genital HSV infection have verified the potential of immunotherapy to reduce recurrences of genital herpes, through use of vaccines, immune response modifiers or a combination of both. This concept has also been extended to recurrent herpes infections of the eye in both murine and rabbit models. Vaccine-based immunotherapy in the treatment of human disease has not been as successful as anticipated, although the optimum strategies that were identified in the animal models have not yet been determined in man. Trials using immune response.

Huse et. al. keeping with the expected size of the fragments based upon the position of the endoproteolytic cleavage. Thus these results indicate that N- and C- terminal cleavage products of BACE endoproteolysis selectively accumulate in cell lines and in vivo. The existence of highly stable, BACE cleavage fragments suggests that this form of BACE may have a specific physiological function in certain tissue and cell types. We further investigated the endoproteolytic processing of BACE in muscle tissue using C2 murine myoblasts which can be induced to differentiate into multinucleated myotubes 39 ; . We found that differentiation dramatically altered the processing of endogenously expressed BACE. Undifferentiated C2 myoblasts exhibited relatively low levels of BACE holoprotein, but not BACE-Ct Fig. 4D ; . However, upon differentiation into myotubes this expression pattern was reversed. While BACE holoprotein was down-regulated note that four times the number of cells were loaded in the C2 lane compared to the C2 Diff ; lane in order to visualize the holoprotein ; , BACE-Ct expression was markedly up-regulated Fig. 4D ; . The specificity of the BACE antibody was confirmed by BACE-Ct peptide antibody preadsorbtion Fig 4D ; . Pulse chase analysis of BACE metabolism in differentiated C2 myotube cultures Fig. 4E ; confirmed the existence of a precursor-product relationship between BACE and BACE-Ct in muscle tissue with kinetics similar to those observed in other non-neuronal cell types Fig. 2A-B ; . These findings demonstrate that endoproteolytic conversion of BACE is a marked feature attending muscle differentiation, suggesting a physiological role in the specification of muscle cells, and perhaps, more broadly, in tissue development. Cell types containing endoproteolyzed BACE retain -secretase activity. We next asked if -secretase activity and A production can occur in cells where endogenous BACE is expressed in the endoproteolyzed form. Because BACE-Ct fragments are highly expressed in.
Many typical antipsychotics available overseas such as perphenazine, are not marketed in Australia. The typical antipsychotics available differ markedly in their adverse effect profiles; hence, caution is required when applying the results of CATIE to Australian patients. While typical antipsychotics are not currently advocated as first-line treatment for all patients, they should not be discounted as a potential therapeutic option for certain individuals. CATIE has shown that of the drugs studied, there is no antipsychotic that is clearly more effective and better tolerated than other antipsychotics. Choice of antipsychotic should be tailored to the individual taking into account efficacy, adverse effect profile and cost and naloxone.
Level is not changed 42 ; . These results show that arginase regulates plasma arginine and proline levels. Wei et al. 53 ; reported that arginase I plays a potentially important role in controlling proliferation of rat aortic smooth muscle cells by providing ornithine for the production of polyamines. Our present data show that mRNA for ODC, a rate-limiting enzyme in polyamine synthesis, was induced by bleomycin treatment. Therefore, we propose that ODC is induced to provide polyamines for the proliferation of cells such as fibroblasts during processes of tissue repair. Under normal conditions, arginase I is expressed almost exclusively in the cytosol of hepatocytes, where it serves as the final enzyme of the urea cycle. Expression of arginase I in the liver is regulated by dietary protein 33 ; and by hormones such as glucagon and glucocorticoids 46 ; . More recently, arginase I was found to be induced also by LPS, interleukin IL ; -4, cAMP, and hypoxia in macrophages 26, 27, 34, ; and by LPS in macrophages of various tissues of rats and mice 40, 45 ; . IL-4 is also known to induce collagen synthesis in fibroblasts in vitro 31 ; . On the other hand, lung IL-4 expression was detected in a murine model of bleomycin-induced pulmonary fibrosis 12 ; . These results suggest a potential role for IL-4 in pulmonary fibrosis. Perhaps because of the potential to stimulate and amplify inflammatory responses, IL-4 stimulates collagen synthesis in lung cells and thus promotes the progression of fibrosis in the end stage of lung disease. If this proposal is tenable, bleomycin may induce arginase I through the induction of IL-4. Transforming growth factor TGF ; - is known to enhance the expression of the lung matrix that causes fibrosis. Boutard et al. 4 ; reported that TGF- stimulates arginase activity in macrophages. Durante et al. 11 ; found that TGF- stimulates arginine transport and metabolism in vascular smooth muscle cells. Induction of TGF- in the bleomycin-treated lung has been repeatedly reported. Therefore, TGF- is a good candidate of arginase-inducing cytokines. We observed that arginase I is induced in alveolar macrophages by bleomycin treatment. Although there have been reports 18, 41 ; concerning the expression of arginase in alveolar macrophages, this is apparently the first report showing a relationship between arginine metabolic enzymes and bleomycin-treated lung fibrosis. In the process of fibrosis, the demand for proline increases as it is required for the synthesis of collagen fiber. Arginase I in alveolar macrophages may contribute to the supply of proline for collagen synthe and murine.
