Abstract
INTRODUCTION Tilapia (Oreochromis niloticus) is an important cultured fish that is widely distributed in Bangladesh. This study was conducted to improve the growth performance and nutrient contents of the fish using five different types of feeds. METHODS Tilapia fingerlings were fed two types of commercial fish feeds (Feed-1 and Feed-2), Spirulina flakes (Feed-3), Feed-2 mixed with Spirulina flakes (Feed-4) and manually mixed feed made from a mixture of mustard oil cake and rice bran (Feed-5). After 4 weeks of being fed with the diets, growth parameters and meat nutrient composition of the tilapia fingerlings were recorded. RESULTS Significant growth in length and weight was observed in juvenile tilapia fish fed with commercial Feed-1 only, while growth performance varied significantly among fingerlings fed other types of feeds. Body tissue calcium (92.8 mg/100 g), iron (1.29 mg/100 g) was higher in fishes fed with dry Spirulina flakes (Feed 3), while the highest amount of zinc (2.09 mg/100 g) was recorded in fishes fed Feed-5. Protein (13.32%) content was highest in fish fed Feed-2 mixed with Spirulina flakes (Feed-4). CONCLUSION Meat nutritional quality of tilapia can be improved by combining commercial feeds with Spirulina flakes, compared with feeding commercial feeds in isolation.

Abstract
The objectives of this study were to assess the sociodemographic profile and to identify the risk factors of ante-partum fetal death which occurs after the age of viability of fetus. This prospective observational study was conducted in the Obstetrics department of Ad-din Women Medical College Hospital during the period of June, 2009 to July, 2010. A total of 14,015 pregnant patients were admitted in the study place after the age of viability, which was taken as 28 weeks of gestation for our facilities. Eighty-three (0.59%) of them were identified as intrauterine fetal death. Assessment of maternal sociodemographic characteristics and maternal-fetal risk factors were evaluated with a semi structured questionnaire pretested. Majority (81.92%, n=68) of the patients were below 30 years of age, 78.31% belonged to middle socioeconomic group. Almost 58% women had education below SSC level and 28.91% took regular antenatal checkup. About 61.45% patients were multigravida. Most (59.04%) ante-partum deaths were identified below 32 weeks of pregnancy. Out of 83 patients, maternal risk factors were identified in 41(49.59%) cases where fetal risk factors were found in 16(19.27%) cases; no risk factors could be determined in rests. Hypertension (48.78%), diabetes (21.95%), hyperpyrexia (17.3%), abruptio placentae (4.88%) and UTI (7.36%) were identified as maternal factors; and congenital anomaly (37.5%), Rh incompatibility (37.5%), multiple pregnancy (12.5%) and post-maturity (12.5%) were the fetal risk factors. Here, proximal biological risk factors are most important in ante-partum fetal deaths. More investigations and facilities are needed to explain the causes of antepartum deaths.

Abstract
OBJECTIVE Patients with sepsis often have elevated cardiac troponin I even in the absence of coronary artery disease. The prognostic value of cardiac troponins in critically ill patients with sepsis remains debatable. Our objective was to evaluate the prognostic value of cardiac troponin I in critically ill patients with severe sepsis. METHODS In this retrospective study, we included patients with severe sepsis who had troponin assayed within 12 h of admission to intensive care over a 6 year period. Patients who had myocardial infarction at intensive care admission in the setting of sepsis were excluded. Included patients were classified into two groups based on their serum troponin I levels: low troponin group (troponin ≤ 0.1 µg/L) and elevated troponin group (troponin > 0.1 µg/L). The primary outcome of interest was hospital mortality. The secondary outcome measures included intensive care mortality, intensive care and hospital length of stay. RESULTS A total of 382 patients were admitted to intensive care with sepsis. Of these, 293 patients were included in analyses. There was a statistically significant difference in hospital (15% vs 36.1%; P < 0.01) and intensive care (11% vs 25%; P < 0.01) mortality, but not in intensive care and hospital duration of stay. Logistic regression analysis revealed temperature, simplified acute physiology score II and serum lactate to be independent predictors of hospital mortality. Cardiac troponin I was not an independent predictor of hospital mortality. CONCLUSION Critically ill patients with severe sepsis who had elevated troponin had increased hospital and intensive care mortality. However, cardiac troponin I did not independently predict hospital mortality.

Abstract
The antiviral drug acyclovir or its analogue, valacyclovir, has been applied in various trials on Bell's palsy with inconsistent results. We compared the therapeutic effect of famciclovir plus prednisolone with prednisolone alone, in patients with Bell's palsy. In a randomized, prospective trial, 68 patients were randomized to treatment with famciclovir and prednisolone (34 patients) or prednisolone alone (34 patients). All patients underwent supportive therapy. Severity of Bell's palsy was evaluated using the House-Brackmann scale (HBS). Follow-up was done after 1 week, 1 month and 3 months, with complete recovery defined as House-Brackmann grade I. The analysis revealed that recovery rates at month 1 and 3 were significantly higher in combination group than that of prednisolone only group (94.1% vs. 61.8% and 97.1% vs. 74.5% respectively). Again recovery from mild to moderate (HBS-II, III, IV) Bell's palsy occurred completely at month 3 and that of severe (HBS-V, VI) Bell's palsy was two-third of the patients. Again in severe Bell's palsy combination treatment increased the chance of complete recovery more than 10-fold than that of steroid only. The study results suggest that better outcome for Bell's palsy patients occurred if they were treated with prednisolone and famciclovir combination instead of prednisolone alone. In fact a considerable number of patients were benefited from additional antiviral therapy with famciclovir.

Abstract
Sezary syndrome is a rare form of primary cutaneous T cell lymphoma. A male patient of 37 years old was reported with multiple subcutaneous swelling at different parts of the body which were asymptomatic for the last 2 years. But he had persistent generalized itching, induration in skin surface and erythema for months. The disease was diagnosed by the presence of Sezary cells in the skin biopsy, peripheral blood smears and epidermotrophism of lymphocytes. The patient was treated by CHOP (Cyclophosphamide, Doxorubicin, Vincristine and Prednisolone) therapy.

Abstract
Tinea (pityriasis) versicolor is a superficial fungal infection and one of the most commonly found pigmentary disorders of skin caused by the yeast Malassezia. Multiple topical as well as systemic therapies are available for treatment. Systemic therapies are used for extensive disease, frequent relapse or where topical agents have failed. The aim that translates the rationale of the study was to compare the efficacy, safety, tolerability and cost effectiveness of single dose 400mg versus 7 day 200 mg daily dose of itraconazole in the treatment of tinea versicolor. A clinical study was done to compare the efficacy of single dose (400 mg) of itraconazole and 7 day 200 mg daily dose of itraconazole in the treatment of extensive tinea versicolor. Total 60 patients (aged 18-50 years) were selected for the study during the period of June 2007 to May 2008 in the department of Dermatology of three different hospitals in Bangladesh. Cases having with extensive involvement, diagnosed clinically and confirmed by wood's lamp and KOH microscopy were taken. Patients were randomly allocated into equal groups. Group A was given single dose 400 mg itraconazole and Group B was given 7 day 200 mg daily itraconazole. Fifty three (88%) male and 7(12%) female were included in the study. The mean age of group A was 32.37+/-9 years and in group B 33.23+/-8 years. The mean duration of the disease in group A was 2.63+/-2 months and 2.76+/-2 months in group B. In group A clinical responders was found cure 22(73.33%) and improvement 5(16.33%) and in group B it was found cure 24(79.99%) and improvement 4(13.33%). The measure at the End point (EP1) equals to 90% response and in-group B it was found cure 24 (79.99%) and improvement 4(13.33%). (Here the End point EP2) equals to 93.33%. The EP clinical analysis however shows 91.66% response. Both single dose and 7 day daily dose of itraconazole can be effective in the treatment of tinea versicolor with extensive involvement but single dose appears to be better for improving compliance and decreasing the cost of treatment.

Abstract
Antigenic determinants expressed on the bacterial cell surface are of importance in the serological characterization and microbiological diagnosis. The bacterial strains carrying these identical or similar antigenic epitopes might react with antibodies produced against other strains. In this study, strong immunogenicity and antigenic cross reactivity were demonstrated among V. cholerae O1, S. flexnerii 2a and H. influenzae b surface components. The enzyme linked immunosorbent assay (ELISA) results were supported by Western blot analysis, where at least 20 antigenic bands, were obtained in each of the reactions, when the surface components were reacted with the homologous antisera. The indirect ELISA results also demonstrated high degree of antigenic relatedness between the surface components of these species, where each surface component was reacted with the heterologous antisera. Western blot analysis also revealed cross reactions between the surface components suggesting common distribution of antigens/epitopes in these bacterial species. This study, thus, gave a clear idea of the level of antigenic sharing and variations among the pathogenic V. cholerae O1, S. flexneri 2a and H. influenzae b strains, which in future, may help in selecting a proper candidate for vaccines and immunodiagnostics development.

Abstract
Using psi(2S)-->pi;{+}pi;{-}J/psi, J/psi-->gammaeta;{'} events acquired with the CLEO-c detector at the CESR e;{+}e;{-} collider, we make the first observations of the decays eta;{'}-->pi;{+}pi;{-}pi;{0} and eta;{'}-->pi;{+}pi;{-}e;{+}e;{-}, measuring absolute branching fractions (37_{-9};{+11}+/-4)x10;{-4} and (25_{-9};{+12}+/-5)x10;{-4}, respectively. For eta;{'}-->pi;{+}pi;{-}pi;{0}, this result probes the mechanism of isospin violation and the roles of pi;{0}/eta/eta;{'}-mixing and final state rescattering in strong decays. We also set upper limits on branching fractions for eta;{'} decays to pi;{+}pi;{-}micro;{+}micro;{-}, 2(pi;{+}pi;{-}), pi;{+}pi;{-}2pi;{0}, 2(pi;{+}pi;{-})pi;{0}, 3(pi;{+}pi;{-}), and invisible final states.

Abstract
Using 2.45x10;{7} psi(2S) decays collected with the CLEO-c detector at the Cornell Electron Storage Ring we present the most precise measurements of magnetic dipole transitions in the charmonium system. We measure B(psi(2S)-->gammaeta_{c})=(4.32+/-0.16+/-0.60)x10;{-3}, B(J/psi-->gammaeta_{c})/B(psi(2S)-->gammaeta_{c})=4.59+/-0.23+/-0.64, and B(J/psi-->gammaeta_{c})=(1.98+/-0.09+/-0.30)%. We observe a distortion in the eta_{c} line shape due to the photon-energy dependence of the magnetic dipole transition rate. We find that measurements of the eta_{c} mass are sensitive to the line shape, suggesting an explanation for the discrepancy between measurements of the eta_{c} mass in radiative transitions and other production mechanisms.

Abstract
Pregnancy outcome among women in the age group of 35 years and more are considered to be less favorable than those of younger women. To observe those, this case control study was conducted in the department of Obstetrics & Gynaecology, Mymensingh Medical College Hospital during the period of 1st June 2003 to 31st May 2004. The study includes 100 patients of 35 years of age or above and 100 controls of 20-30 years of age. Observed complications during the pregnancy and delivery were increased incidence of placenta previa, malpresentation, intrauterine death, preterm labour, obstructed labour ruptured uterus etc. Pregnancy related complications were found significantly high (p<0.001) in case group (80%) compared to control group (51%). Rate of caesarian section was also more among the cases. Post delivery maternal complications were more in case group (53%) compared to control (30%) (p<0.001). Perinatal morbidity and mortality was significantly high. Cause of late fetal death in older women include, failure of the uterine vasculature in older women to adapt sufficiently to the increase haemodynamic demands of pregnancy, reduced fetal oxygenation with maternal age and also a rise in the frequency of preexisting hypertension with age. Maternal age is an important and independent risk in pregnancy outcome.

Abstract
PURPOSE Leiomyosarcoma is a rare neoplasm. There is paucity of literature in regards to paraovarian leiomyosarcoma with metastases to the scalp. We present a 72-year-old woman with metastases to the scalp from a primary paraovarian high grade leiomyosarcoma. METHODS AND RESULTS The patient underwent a total abdominal hysterectomy, pelvic and aortic lymphadenectomy, excision of Meckel's diverticulum, and radical pelvic tumor debulking with sigmoid colectomy and end-to-end anastomosis and six cycles of taxotere/carboplatin. She presented 18 months later with metastatic high-grade leiomyosarcoma to the scalp. The lesions were excised and she is now receiving palliative taxotere and gemcitabin. CONCLUSION High-grade leiomyosarcoma is known for its resistance to chemotherapy, radiation therapy, and propensity for hematological dissemination with an overall poor prognosis.

Abstract
We report the first observation of Upsilon(2S)-->etaUpsilon(1S), with a branching fraction B=(2.1(-0.6)+0.7(stat)+/-0.3(syst)) x 10(-4) and a statistical significance 5.3sigma. Data were acquired with the CLEO III detector at the CESR e+e(-) symmetric collider. This is the first process observed involving a b-quark spin flip. For related transitions, 90% confidence limits in units of 10(-4) are B(Upsilon(2S)-->pi0Upsilon(1S)) < 1.8, B(Upsilon(3S)-->etaUpsilon(1S)) < 1.8, B(Upsilon(3S)-->pi0Upsilon(1S)) < 0.7, and B(Upsilon(3S)-->pi0Upsilon(2S)) < 5.1.

Abstract
A precision measurement of the mass of the h_{c}(1P1) state of charmonium has been made using a sample of 24.5x10;{6} psi(2S) events produced in e;{+}e;{-} annihilation at the Cornell Electron Storage Ring (CESR). The reaction used was psi(2S)-->pi;{0}h_{c}, pi;{0}-->gammagamma, h_{c}-->gammaeta_{c}, and the reaction products were detected in the CLEO-c detector. Data have been analyzed both for the inclusive reaction and for the exclusive reactions in which eta_{c} decays are reconstructed in 15 hadronic decay channels. Consistent results are obtained in the two analyses. The averaged results of the present measurements are M(h_{c})=3525.28+/-0.19(stat.)+/-0.12(syst.) MeV, and B(psi(2S)-->pi;{0}h_{c})xB(h_{c}-->gammaeta_{c})=(4.19+/-0.32+/-0.45)x10;{-4}. Using the ;{3}P_{J} centroid mass, DeltaM_{hf}(1P) identical withM(chi_{cJ})-M(h_{c})=+0.02+/-0.19+/-0.13 MeV.

Abstract
We measure the mass of the eta;{'} meson using psi(2S)-->pi;{+}pi;{-}J/psi, J/psi-->gammaeta;{'} events acquired with the CLEO-c detector operating at the CESR e;{+}e;{-} collider. Using three decay modes, eta;{'}-->rho;{0}gamma, eta;{'}-->pi;{+}pi;{-}eta with eta-->gammagamma, and eta;{'}-->pi;{+}pi;{-}eta with eta-->pi;{+}pi;{-}pi;{0}, we find M_{eta;{'}}=957.793+/-0.054+/-0.036 MeV, in which the uncertainties are statistical and systematic, respectively. This result is consistent with but substantially more precise than the current world average.

Abstract
Using a total of 2.74 x 10(7) decays of the psi(2S) collected with the CLEO-c detector, we present a study of chi(cJ)-->gammaV, where V=rho(0), omega, phi. The transitions chi(c1)-->gammarho(0 and chi(c1)-->gammaomega are observed with B(chi(c1)-->gammarho(0))=(2.43+/-0.19+/-0.22) x 10(-4) and B(chi(c1)-->gammaomega)=(8.3+/-1.5+/-1.2) x 10(-5). In the chi(c1)-->gammarho(0) transition, the final state meson is dominantly longitudinally polarized. Upper limits on the branching fractions of other chi(cJ) states to light vector mesons are presented.

Abstract
We search for a non-SM-like CP-odd Higgs boson (a(1)(0)) decaying to tau(+)tau(-) or mu(+)mu(-) in radiative decays of the Upsilon(1S). No significant signal is found, and upper limits on the product branching ratios are set. Our tau(+)tau(-) results are almost 2 orders of magnitude more stringent than previous upper limits. Our data provide no evidence for a Higgs state with a mass of 214 MeV decaying to mu(+)mu(-), previously proposed as an explanation for 3 Sigma(+)-->pmu(+)mu(-) events observed by the HyperCP experiment. Our results constrain NMSSM models.

Abstract
We report the first observation of the decay J/psi-->3gamma. The signal has a statistical significance of 6sigma and corresponds to a branching fraction of B(J/psi-->3gamma)=(1.2+/-0.3+/-0.2)x10;{-5}, in which the errors are statistical and systematic, respectively. The measurement uses psi(2S)-->pi;{+}pi;{-}J/psi events acquired with the CLEO-c detector operating at the CESR e;{+}e;{-} collider.
