Abstract
The Federal Government of Nigeria (FGN) has committed to net-zero emission development pathways to respond to the Paris Agreement adopted in 2015. However, the country is in dire need of energy to support its developmental ambitions. Therefore, it is necessary to consider green energy technologies to support both socioeconomic development and to meet the FGN's emission reduction target. In view of this, the current work presents the optimal sites for bioenergy plants in a state in Nigeria using Geographic Information System (GIS). Key findings suggest that 62.03 PJ/yr and 4.12 PJ/yr of energy could be derived from crop residues and forest residues, respectively, to support the state's bioenergy development. The crop residues considered include plantain (stem), oil palm (shell and fibre), maize (stalks) and cassava (peel and stalks). Six criteria were used in selecting the optimal sites, and include biomass residue distribution, settlement, road accessibility, nearness to waterline, slope and aspect. These criteria were incorporated into the ArcGIS platform through the weighted overlay tool. Strategically, the analysis presents seven sites for biomass plants to sustainably meet part of the energy needs. The efforts of the current work which supports not less than three SDGs-SDG 7 (Clean and Affordable Energy), SDG 12 (Responsible Consumption and Production) and SDG 13 (Climate Action), will assist policymakers in Nigeria to make appropriate policies within the climate change space.

Abstract
ABSTRACT. In dye-sensitized solar cells, transparent metal oxide working electrodes play a vital role in defining the power conversion efficiency. It was found that the size of nanoparticles influences the electrical, optical properties of these electrodes. Herein, we describe the synthesis of ZnO with zinc acetate dihydrate and different stabilizers (diethylamine and triethylamine) by using a modified solvothermal process. The obtained materials were characterized by XRD, SEM, EDX, TEM, HRTEM, UV-visible, FTIR, and Raman methods. The crystallite sizes for ZnO-1 and ZnO-2 samples were indexed as 39.0 and 40.5 nm for the highest peak intensity with diethylamine and triethylamine stabilizer, respectively. We examine the effect of stabilizers on the morphology, optical band gap, and photovoltaic performance of the prepared ZnO. We found that ZnO prepared using diethylamine stabilizer exhibiting significant efficiency of 1.45%, open-circuit voltage 0.454 V, short-circuit current density 2.128 mA/cm2, and 0.66 fill factor were achieved under 44 mW/cm2 illumination powers with dye-3.

Abstract
Introduction/Objective
Diarrhea is a major source of morbidity and mortality in low-income and middle-income countries. In underdeveloped countries, diseases caused by viruses identified in environmental samples cause major health problems. Little knowledge about the frequency and pattern of viral contamination of drinking water sources in these resource-poor settings. Adenovirus which causes watery diarrhea, particular has been recognized as important causal pathogen. Adenovirus remains a global threat to public health and an indicator of inequity and lack of social development. Tap water samples from coastal sites in Karachi between 2019 and 2020 over a period of 11 months. The total of 40 tap water sample was examined for infectious Adenovirus by a real time polymerase chain reaction (PCR) amplification.

Abstract
The genital chlamydial infection is the most common sexually transmitted diseases (STD) and major cause of infertility and ectopic pregnancy for millions of women in the world particularly in developing countries. This study was performed to find out the seroprevalence of Chlamydia trachomatis (CT) genital infection in women of reproductive age attending the Department of Obstetrics and Gynaecology, Mymensingh Medical College Hospital (MMCH) during the period from January 2009 to December 2009 through a cross sectional study. A total of 108 serum samples from symptomatic and asymptomatic pregnant and non-pregnant women were tested for CT specific IgG antibody by Enzyme Linked Immunosorbent Assay (ELISA). A total of 31(28.7%) patients were found to have antibody of which 44% (26/59) were from pregnant group and 10.2% (5/49) from non-pregnant group. The seropositivity was 21.6% (16/74) in symptomatic cases and 44.1% (15/34) in asymptomatic cases. The study shows high prevalence of Chlamydial antibody which is common in pregnant and non-pregnant, symptomatic and asymptomatic adult women in Bangladesh. So, screening for chlamydial infection should be done routinely by suitable tests in sexually active symptomatic and asymptomatic women including pregnant women to prevent serious complications.

Abstract
Puerperal sepsis is an important cause of maternal morbidity and mortality in developing countries. This study was undertaken to isolate and identify the anaerobic bacterial agents of puerperal sepsis among the patients admitted in Mymensingh Medical College Hospital (MMCH) during the period from July 2006 to June 2007. Endocervical swabs/secretions were collected from 50 cases of puerperal sepsis and were cultured anaerobically. Anaerobiasis was done by using gas pack (BD GAS PAK TM EZ) in anaerobic jar. Out of 50 samples, 42(84%) yielded growth in cultures. Among 42 culture positive cases, 20(40%) were Aerobic organisms and 22(44%) were mixed, i.e., Aerobic and Anaerobic bacteria. The isolated Anaerobic organisms were Peptostreptococcus 14(63.63%), Bacteroides fragilis 3(13.64%), Prevotella melaninogenica 3(13.64%) and Clostridium perfringens 2(9.09%). As a preliminary study, it was observed that anaerobic culture could be carried out with available logistic arrangement. So, it was recommended to design further study on anaerobic bacterial isolation with particular emphasis on their antimicrobial susceptibility.

Abstract
Conjoint twins have always been a surgical challenge. The authors report an unusual finding in a surviving epigastric heteropagus twin. A 17 year old boy who underwent laparotomy for acute intestinal obstruction revealed a blind ending but complete duplication of the large bowel and an accessory liver in the falciform ligament, along with a separate gall bladder but with fused bile ducts. The findings suggest that the duplicated bowel loop and the accessory liver were remnants of the incomplete parasite twin, assimilated into the body of the autosite, which remained asymptomatic for 17 years. This case is being reported because of the uniqueness of the finding.

Abstract
The effects of different pesticides (propiconazole, profenofos, pretilachlor) on vermicomposting were evaluated for the adverse effects on soil enzyme activities (dehydrogenase, phosphatase, urease) and total microbial counts (TMC). There were remarkable increase in enzyme activities and TMC in presence of earthworm compared to control (earthworm absent). In comparison to control, the activities of phosphatase, dehydrogenase and urease in presence of vermicompost increased upto 30, 128 and 31.3% respectively; whereas increase of TMC was 71.9%. But, in presence of each of the pesticide, said activities decreased. Maximum inhibition of soil phosphatase activity (46.6%) was observed in presence of propiconazole (100 mg kg(-1)) after 120 days. Profenofos affected the soil dehydrogenase activity in the tune of 47% at 1000 mg kg(-1) concentration after 80 days and thereafter, the extent of toxicity decreased little. Soil urease activity was affected markedly in presence of profenofos and was 62% at 1000 mg kg(-1) level after 80 days. TMC also declined in presence of profenofos and pretilachlor. Increase in TMC was about 71.9% compared to control and the inhibition was more or less 60% when profenofos (1000 mg kg(-1)) was present even after 120 days of treatment.

Abstract
A study was conducted on 130 patients suffering from skin lesions which included psoriasis, lichen planus, DLE, pemphigus, vitiligo and alopecia areata. Forty age-and-sex-matched healthy individuals served as control. Serum IgG, IgM, and circulating immune complexes (CIC) were estimated. Significant increase in serum IgG (1937.2 +/- 1030.43 mg%) and IgM (232.12 +/- 136.98 mg%) was observed in all the skin lesions when compared with controls except in lichen planus where they were significantly lowered, values being 580.61+/- 77.35 mg% and 66.88 +/- 6.59 mg% respectively. CIC levels were significantly raised (P< 0.00 1) in various skin lesions (40.49+/-23.29) when compared with controls (17.68+/- 3.21), but no significance was observed in lichen planus( 17.72 +/- 4.28). Serum IgG, IgM and CIC were statistically significantly altered depending on the extent of the lesion and lowered significantly to almost normal values following treatment, thereby confirming the role of immunity in the pathogenesis of these skin disorders.

Abstract
Total microbial count was highly affected (up to 61% at 1000 micrograms level) in presence of hexaconazole and persisted up to 21 days. Bacteria were more susceptible than actinomycetes. Carbofuran and ethion were moderately toxic to soil microflora. Inhibitory effects of all the three pesticides gradually decreased after 21 days as was evident by increase in total microbial count except in carbofuran. GDH activity in soil was also affected initially (up to 14 days) by all the three pesticides (60.3% in hexaconazole at 1000 micrograms level) and inhibition gradually decreased to zero except in carbofuran (15-20% toxicity persisted up to 35 days). GDH and LDH activity in presence of hexaconazole was strongly affected in intact cells of some standard culture of bacteria like Rhizobium sp. (host Dolichos sp., 32.1 and 72.5%), Bacillus subtilis Cohn (86.75 and 76.5%), Azotobacter sp. (36.9 and 55.4%) and B. sphaericus (67.6% GDH) respectively. Carbofuran inhibited the enzyme activity in B. subtilis (55.55 and 35.3%) and to some extent in B. sphaericus. Ethion moderately inhibited LDH activity in Rhodococcus sp. AK1 (17.1 and 33.3%), Rhizobium (27.6% LDH), E. coli HB 101 (34.2% LDH) as evidenced by formazan formation. From the result, it might be concluded that among the above three pesticides tested hexaconazole strongly inhibited the dehydrogenase system in bacteria including nitrogen fixing bacteria of soil and thus may affect soil fertility. It was concluded that hexaconazole was more toxic than ethion to dehydrogenase enzymes.

Abstract
Cell mediated immunity was studied in 50 patients of leprosy and 15 control volunteers, by estimation of peripheral blood lymphocytes (PBL), total rosette forming cells (TRFC) and active rosette forming cell (ARFC) counts in vitro. PBL, TRFC and ARFC counts were slightly but not significantly increased in patients of tuberculoid leprosy (TT) and muculoanaesthetic variant of tuberculoid leprosy as compared to control group. However, gradual decrease in T-cell subsets, occurred in borderline tuberculoid leprosy (BT) as compared to tuberculoid type (TT)-(p < 0.05). Significant decrease in lymphocytes and T-cell subsets was observed in midborderline leprosy (BB), (p < 0.01):borderline lepromatous leprosy (BL), (p < 0.001) and lepromatous subpolar and polar types (LL); (p < 0.001) as compared to control group. Mycobacterium leprae (M.leprae) were positive in BT-(20%); BB-(72.7%); BL-(83.2%) and LL-(100%). Delayed hypersensitivity reactions (DHR) revealed significantly increased lepromin positivity in TT (83.3%) and BT (80%) which decreased in BB (63.6%) and BL (50%). Lepromin test showed anergic state in LL group (28.5% positivity). Dinitrochlorobenzene (DNCB) skin test showed 100% positivity in TT group and controls while gradual significant decrease was observed from BT (p < 0.05) to LL scale (p < 0.001). Leprosy spectrum of Ridley and Jopling scale is directly co-related with inherent cell mediated immune status of the patients which has a significant prognostic role in treatment and long term management.

Air-insufflation during endoscopy caused distension of the stomach inside the chest leading to respiratory distress. When part of the stomach is intrathoracic, the endoscopist should be cautious and the possibility of respiratory embarrassment kept in mind during air-insufflation.

Abstract
Percutaneous transhepatic cholangiography (PTC) using Chiba needle was employed to diagnose obstructive jaundice in 31 subjects. It was successful in all 27 (87%) subjects who had dilatation of the biliary tree. Out of them, 15 had features suggestive of carcinoma, 9 had features of stone and 3 had features of stricture of the common bile duct (CBD). Surgery was done in 11 cases and PTC diagnosis of carcinoma of CBD in 4 and stricture of the same in one subject were confirmed. While in the remaining 6 subjects with a PTC diagnosis of CBD stone, 4 were found to be so and 2 had stricture of the duct. Three subjects had complications such as bile peritonitis, cholangitis and shock. In majority of the cases, the biochemical parameters were inconclusive. These results suggest that PTC may be useful in the diagnosis of obstructive jaundice and this procedure should be employed more widely.
