Abstract
Although molecular profiling of DNA isolated from formalin-fixed, paraffin-embedded (FFPE) tumor specimens has become more common in recent years, it remains unclear how discrete FFPE processing variables may affect detection of copy number variation (CNV). To better understand such effects, array comparative genomic hybridization (aCGH) profiles of FFPE renal cell carcinoma specimens that experienced different delays to fixation (DTFs; 1, 2, 3, and 12 hours) and times in fixative (TIFs; 6, 12, 23, and 72 hours) were compared to snap-frozen tumor and blood specimens from the same patients. A greater number of regions containing CNVs relative to commercial reference DNA were detected in DNA from FFPE tumor specimens than snap-frozen tumor specimens even though they originated from the same tumor blocks. Extended DTF and TIF affected the number of DNA segments with a copy number status that differed between FFPE and frozen tumor specimens; a DTF ≥3 hours led to more segments, while a TIF of 72 hours led to fewer segments. Importantly, effects were not random as a higher guanine-cytosine (GC) content and/or a higher percentage of repeats were observed among stable regions. While limiting aCGH analysis to FFPE specimens with a DTF <3 hours and a TIF <72 hours may circumvent some effects, results from FFPE specimens should be validated against fresh or frozen specimens whenever possible.

Abstract
Varicose veins are part of the spectrum of chronic venous disease and include spider telangiectasias, reticular veins, and true varicosities. It may present without advanced signs of chronic venous insufficiency. Sclerotherapy is a treatment choice for patients with varicose veins of lower extremity; it uses the intravenous injection of chemical drugs to achieve the goal of inflammatory occlusion. Phlebectomy, a minimally invasive procedure usually used for higher diameter of varicose veins at the surface of the skin. Objective of the study was to compare the outcome of Phlebectomy and Sclerotherapy in varicose vein patients. It was a quasi experimental study was conducted in the Department of Vascular Surgery in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka during the period of June 2019 to May 2020. Patients admitted with varicose vein and varicosity of the lower limbs with valves and perforator incompetence in the Department of Vascular Surgery, BSMMU, Dhaka, Bangladesh. During this period 60 patients were selected purposive randomly. Patients were divided to 30 patients were treated with Phlebectomy (Group I) 30 patients were treated with Sclerotherapy (Group II). Data were collected according to the pre-designed semi-structured data collection sheet. After editing data analysis were carried out by using the Statistical Package for Social Science (SPSS) version 22.0 Windows software. This study shows average age 40.73±15.50 years in Phlebectomy (Group I) and 38.43±11.08 years in Sclerotherapy (Group II). Males are more commonly involved than females between two groups which was 76.7% in Phlebectomy (Group I) and 70.0% in Sclerotherapy (Group II). The change CEAP improved to 93.3% in patients who underwent phlebectomy when compared to 83.3% in patients who underwent sclerotherapy. During the follow-up with duplex at treated veins showed 93.3% complete occlusion of treated veins in the phlebectomy group, while only 70.0% of the patients in the sclerotherapy group showed evidence of complete occlusion. In phlebectomy group recurrence of leg varicosities were found 6.7% of the patients, while 26.7% of the patients in the sclerotherapy group. The difference was statistically significant between two groups (p=0.038). This study shows phlebectomy to be much better option than sclerotherapy for the treatment of varicose veins and hence can be used routinely. Both phlebectomy and sclerotherapy not only revealed minimal time taken for return to normal activity but also proved to be safer with regard to complications.

Abstract
Parthenium hysterophorus L. is a noxious alien invasive weed species rapidly spreading in Bangladesh. P. hysterophorus examined the prospects of using allelopathic extracts during the period of July 2021 to June 2022. Experiments were conducted in the net house at Sher-e-Bangla Agricultural University, in non-cropped areas of Khustia and cropped areas of Chudanga. The net house experiments were laid out in complete randomized design (CRD) and replicated three times separately for each growth stage. Results showed that by using pretilachlor, pendimethalin, bensulfuron methyl + pretilachlor, bensulfuron methyl + acetachlor, oxadiazon, and pyrazosulfuron-ethyl + pretilachlor decreased the seed germination of parthenium at pot bioassay under both puddle and dry sown condition. At rosette stage of parthenium weed, glyphosate and carfentrazone ethyl (5%) + glyphosate with ½, ¾, and full doses gave 100% mortality at three weeks after treatment (WAT). In cropped areas carfentrazone Ethyl (5%) + glyphosate (36%) and quizalofop-p-ethyl resulted in a 100% and 90% mortality rate at 21 DAT. Overall, the efficacy of herbicides was more effective on rosette parthenium than bolted plants. A phytotoxic response to weed growth was induced by aqueous extracts of Oryza sativa L. var. Boteswar, Triticum aestivum L. var. BARI gom-21, Helianthus annus L., Datura metel, Mangifera indica L., Delonix regia, and Acacia nilotica. Delonix regia was the most effective for inhibition of germination (29%). Whereas Datura metel extracts and Oryza sativa var. Boteswar straw extracts significantly reduced root (1.5 mm) and shoot (3.8 mm) length.

Abstract
Domestic violence is a global problem and it affects millions of people and often results in physical, sexual and emotional injuries and even deaths. The study was to assess the prevalence, form and reasons of domestic violence among the female garment workers in Dhaka, Gazipur and Narayanganj of Bangladesh. This Cross sectional descriptive study was conducted at four Garments in Bangladesh named Tusuka Fashions Limited Dhaka, Ananta Casual Wear Limited, Gazipur, Spectra Sweaters Limited, Dhaka and Modele de capital Limited Narayanganj from January 2019 to December 2019. Three hundred and six (306) female garment workers were taken as sample. A semi-structured questionnaire and Abuse Assessment Screen was used. Then in-depth interviews were conducted. The study results revealed that the mean age of the respondents was 29.85 years and almost two-third (69.0%) of the respondents was Muslim. About 246(81.0%) were married and 164 (64.06%) had 1-2 children. Two third respondents (63.0%) were married for 5-15 years and 72.0% lived in nuclear families and the majority (39.5%) of the respondents had monthly income of BDT 15000-30000 where mean monthly income was BDT ±23,529. Proportion of Domestic Violence was 15.4% and all of them (100.0%) were the victim of both physical and mental violence. Husband was the perpetrators in 98.0% cases and most of the cases (43.0%) reason of domestic violence was relationship doubt with another person. Significant difference (p<0.05) found between domestic violence with religion and marital status, duration of marriage, number of children and family monthly income. The study findings demand an intensified effort should be made towards creating awareness about the domestic violence and solved this to improve their quality of life.

Abstract
Urinary tract infections (UTIs) are the leading cause of hospitalization due to bacterial infection, and the frequency of multidrug-resistant Escherichia coli isolates from these infections is increasing worldwide. The current study aims to isolate and characterize antibiotic-resistant Escherichia coli and their antibiogram typing from urine samples of humans. From April to December 2019, a total of 60 human urine samples were collected aseptically and treated to primary isolation by propagation in nutrient broth followed by culture on various agar media. Gram’s staining, string techniques, biochemical characterization, PCR, and Sanger sequencing were performed to confirm E. coli. The Kirby-Bauer disk diffusion technique was used to test the susceptibility of all bacterial strains to thirteen typically prescribed antibiotics. The overall prevalence of E. coli in UTIs was 66.67%. Three variations were noted in E. coli, all of which were single substitutions (A>T, C>T, and T>A). Phylogenetic analysis of the 16S rRNA revealed that the E. coli discovered in this study belonged to the genus Escherichia, but was distinct from those identified in other countries. The antibiograms revealed that all the isolates (100%) were resistant to penicillin, ampicillin, and amoxicillin; 94.87% to doxycycline; 79.16% to gentamycin; 75.48% to ciprofloxacin; 73.07% to erythromycin; 71.66% to levofloxacin; 47.36% to ceftriaxone; and 46.66% to tetracycline. In contrast, all E. coli strains were sensitive to amikacin (95%), vancomycin (92.50%), and azithromycin (92.50%). People with a urinary tract infection (UTI) often have multidrug-resistant E. coli in their urine samples, which calls for a one-health strategy to deal with this rapidly changing condition.

Abstract
Streptococcus pneumoniae (SP) infections cause morbidity and mortality among children worldwide. Hence India introduced 13-valent pneumococcal conjugate vaccine (PCV-13) in 2017 in a phased manner. The primary objective of this study was to assess the proportion of healthy children having nasopharyngeal colonization (NP) with SP. Secondary objective was to determine prevalent serotype of SP among the PCV13 vaccinated and non-vaccinated children. This cross-sectional study was conducted in 4 hospitals of Lucknow District, Northern India. Three hundred healthy children (2-59 months) were recruited between July and August 2019 from vaccination-clinics of hospitals. NP specimen was cultured using 5% sheep blood agar plate containing gentamicin. Pneumococcal isolates were identified by optochin sensitivity and bile-solubility tests. Serotyping was done using Quellung Method. Of the 300 healthy children, 56.7% (170/300) were males and 59.3% (181/300) had received at least one dose of PCV13 vaccine. The NP carriage rate of SP among healthy children was 37.7% (113/300). Vaccine serotypes were found in 33.3% (22/66) in PCV vaccinated children and 48.9% (23/47) in non-vaccinated children (p 0.09). Common vaccine serotypes that isolated were: 18C, 19A, 19F, 23F, 3, 4, 6A, 6B, 9 V. Thus more than one-third of healthy children had NP colonization with SP. Adjusting for age, there was a trend for significant reduction in vaccine serotypes in the NP with one doses versus two or more doses (ptrend = 0.04).

Abstract
Abstract
Aim
The British Society of Gastroenterology (BSG) recommends biopsies from two different regions in the oesophagus. A close loop audit was undertaken to assess performance at a district general hospital, against these guidelines and following newly agreed trust guidelines after the first audit cycle of a follow up OGD within 6 weeks of the presentation.
Method
Data was collected of patients admitted with a food bolus over the first cycle (March2019 to February 2021) and the second cycle (1/10/21 to 14/10/21). Exclusion criteria were age of less than 18 and sharp food bolus.
Results
69 patients were identified. Average age was 60 years. There were 67% male patients and 33% female. 20% of patients underwent a follow up OGD in the first cycle and 45%underwent a follow up OGD within six weeks. 7% had two regions biopsy in the first cycle and21% in the second cycle. Average OGD follow up time was 92 days in the first cycle and 59days in the second cycle. Commonest findings on histology results were eosinophilic oesophagitis and Barrett's oesophagus (22% each), GORD (15%) and carcinoma (7%).
Discussion
Food bolus obstruction indicates the presence of pathology of the oesophagus and should be investigated as so, even despite spontaneous recovery from the acute event. Number of patients undergoing OGD within six weeks and a two regions biopsy improved through this audit by implementing the new trust guidelines.

Abstract
Objectives We aim to share the experience of the USAID's Strengthening Multi-sectoral Nutrition Programming through Implementation Science Activity (MSNP), which has been integrating Growth Monitoring (GMP) and Expanded Program of Immunization (EPI) for children under two years in Khulna City Corporation (KCC), Ministry of Local Government Rural Development and Cooperatives (LGRD), Bangladesh. Methods The team analyzed the GMP and EPI service data, observed client-provider interactions (service delivery) (n = 3 nutrition counselors), conducted semi-structured interview with health assistants (n = 6) and informal discussion with mothers (n = 10) who visited the GMP/EPI service facilities from October 2021 to January 2022. Results Both health assistants and nutrition counselors delivered GMP and EPI services, serving as key enablers of EPI-GMP integration. Reminder text messages were sent by MSNP project to mothers of children lost-for-follow-up to encourage their service return. From October 2021 to January 2022 GMP-EPI integrated services were provided to 1518 children (October: 32; November: 281; December: 583; January: 622). Major challenges included coordination gaps between service activities; space constraints to conduct GMP; overburdening of health assistants to fulfil EPI lost-to-follow-up targets during COVID-19 pandemic and priority for vaccination of COVID-19 to EPI; lack of awareness among caregivers of the importance of appropriate nutrition during the child's first 1000 days for healthy physical and mental development. Conclusions Although this experience suggests integration of GMP into EPI can work, improvements are needed. The MSNP project will increase coordination among donors, Ministry of Health and LGRD, KCC and partner NGOs, service providers and mothers to ensure sustained and effective GMP-EPI integration; provide need-based infant and young child feeding counseling and train caregivers on community-based management of acute malnutrition, and strengthen service provision by providing supportive supervision to them.

Abstract
Angiotensin-II is considered as a peptide responsible for the vascular dysfunction and complications in various tissues including liver through inducing free radicle mediated oxidative stress. This study aimed to evaluate the effect of ramipril, an angiotensin-converting enzyme inhibitor (ACE inhibitor), on oxidative stress, inflammation, and fibrosis in the liver of alloxan-induced diabetic rats. In this investigation, rats were divided into four groups (six rats in each group): control, control+ramipril, alloxan, and alloxan+ ramipril. A single dose (90 mg/kg) of alloxan was given intra-peritoneally to induce type two diabetes. After the induction of diabetes, ramipril (10 mg/kg) was administered to each animal for 21 days. An oral glucose tolerance test (OGTT) was performed. All animals were sacrificed at the end of the study. Blood and liver tissues were collected from each animal and stored for further biochemical studies. Liver marker enzymes and oxidative stress parameters were also assayed followed by histological examination in the liver. Alloxan administration in rats showed oral glucose intolerance and increased fasting blood glucose levels. Ramipril (10 mg/kg) treatment in alloxan administered rats improved the OGTT and lowered fasting blood glucose level. This study also revealed the elevation of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) enzymes activities in the alloxan administered rats which were attenuated by ramipril treatment. Oxidative stress parameters such as advanced protein oxidative products (APOP), nitric oxide (NO), and malondialdehyde (MDA) were also increased in alloxan administered rats which were diminished by the treatment of ramipril. Moreover, alloxan administration increased inflammation and fibrosis in the liver, which was further prevented by ramipril treatment. In conclusion, ramipril alleviated oxidative stress and fibrosis in the liver by suppressing oxidative stress. This investigation suggests that ACE inhibitors may be useful for treating diabetic complications and liver injury in alloxan-administered rats.

The Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR) test is one of the most popular and specific diagnostic tests to easily recognize the Peste des Petits Ruminants virus (PPRV) genome in clinical samples. The sensitivity of the RT-PCR test depends on gene-targeted primer sets. The literature appears to be lacking in designing primers used in RT-PCR to detect PPRV genome in Bangladesh. This study aimed to develop an N gene based PPRV primer set, a standardized RT-PCR protocol, and its validity test by comparison with other available primers. A total of seventy clinical samples and ten PPRV positive isolates were used in real-time RT-PCR and conventional RT-PCR using one pair designed primer set NF/NR and three pairs of published gene F1/F2, F1b/F2b and N1/N2. N gene-based PPRV primer sets (NF/NR) were designed from a published sequence of PPRV (Accession number GQ122187.1). Statistical analysis was carried out. The designed N gene-based primer positive PPRV samples were sequenced and analysed. The N gene-based primer sets were more sensitive to PPRV detection than F gene-based primer (P =.002) in the RT-PCR test. PPRV detects the highest (86%) of clinical samples in the RT-PCR test using a designed N gene-based primer. Sequence analysis showed that designed N gene-based the 402bp sequence of PPRV isolates is clustered with other Bangladeshi PPRV isolates and belongs to Lineage IV. New primers sets were designed from the conserved region of the N gene of PPRV. Designed primer sets successfully worked in real-time RT-PCR. The standardized RT-PCR protocol with the designed primer sets (NF/NR) can be used for the specific detection of PPRV from clinical samples.

Abstract
Suicide is a major preventable public health problem globally however, under attended in Bangladesh. It happens because of multi-factorial involvement; nevertheless, past suicidal attempt is a significant predictor of future suicidal behavior. We aimed to assess the suicidal behaviors among the patients visiting for psychiatric care in a tertiary care hospital of Bangladesh. This cross-sectional study was conducted among the patients attending at department of Psychiatry, Bangabandhu Sheikh Mujib Medical University, Dhaka, from March 2018 to February 2019. A total of 379 patients were interviewed with pre-tested semi structured questionnaire. Non probability purposive sampling was used to collect data. Data were entered into Statistical Package for the Social Sciences 16.0 software and analyzed Among the 379 respondents, 197(52%) were male, 52.5% were married. Mean±SD age of the respondents was 29.94±11.32 year ranging from 18 to 75 years. About 24% percent of the respondents had family history of mental illness, 4% had family history of completed suicides. Prevalence of life time suicidal ideation among the patients was found as 32.5%, one-year prevalence rate 26.4%, one month 17.2% and within last two days it was found as 11.3%. The rate of suicidal plan was 14.0%, preparation 10.0% and attempt was 7.4%. Mean±SD age of onset of suicidal ideation was 24.33±8.9 year ranging from 14 to 57 years. About one in three psychiatric patients had life time suicidal ideation. Third decade of life was found to be vulnerable for onset of suicidal thoughts.

Abstract
The Coronavirus disease 2019 (COVID-19) has turned into a worldwide human tragedy and economic devastation. There had an intensive search for an effective drug against the coronavirus but not led to any breakthrough agents. Only one choice was left namely an effective and safe vaccine. Many people are ambivalent regarding corona vaccines because they also fear possible side effects from vaccination. This study was designed to track the side effects after first and second dose of the Oxford-AstraZeneca vaccines used in Mymensingh district of Bangladesh. This cross-sectional descriptive type of observational study was conducted in Mymensingh Medical College, Mymensingh, Bangladesh during the period of five months from 1 February, 2021 to 30 June, 2021 among 293 purposively selected vaccine recipients who received two doses of the Oxford-AstraZeneca vaccines. Data were collected by face to face interview of the selected vaccine recipients using a semi-structured questionnaire. Data were inputted into SPSS version 26.0. Qualitative data were summarized by percentage and quantitative data were summarized by mean and standard deviation. Necessary bivariate and multivariate analysis was done. Mean age of the respondents was 40.3 years with a standard deviation of ±8.7 years. Among the vaccine recipients female were 159(54.3%) and male were 134(45.7%). The most of the vaccine recipients were graduate and master 256(87.3%) and more than half of the vaccine recipients (156, 53.2%) were government service holder. The most of the vaccine recipients (242, 86.0%) were from urban area and 263(89.8%) vaccine recipients were non-smoker. Sixty eight (23.2%) of the vaccine recipients had different types of co-morbidities. It was found that 217(74.1%) vaccine recipients had side effects after first dose while 162(55.3%) had side effects after second dose. The difference in occurrence of side effects of first and second dose was statistically highly significant (p<0.001). Pain on the injection site was present in 172(58.7%) vaccine recipients after first dose and in 142 (48.5%) after second dose. Fever was prevalent in 98 (33.4%) after first dose and in 61 (20.8) after second dose. Headache was in 61(20.8%) and in 22(7.5%) after first and second dose respectively. Thirty one (10.6%) vaccine recipients had loose motion after first dose and 26(8.9%) had this after second dose. First dose of vaccination caused nausea in 28(9.6%) and second dose caused it in 16(5.5%) vaccine recipients. Joint pain was prevalent in 24(8.2%) after first dose and in 15(5.1%) after second dose. Rash was present in 9(3.1%) and in 3(1.0%) after first and second dose respectively. Cough was present in 5(1.7%) after first dose and in 2(0.7%) after second dose. Each 2(0.7%) had history of fainting and bodyache and 1(0.3%) reported intense weakness after first dose only. Side effects of first dose of AstraZeneca vaccine were more prevalent in female (124, 78.0%) than male (93, 69.4%). The side effects of second dose of AstraZeneca vaccine were also more prevalent in female (103, 64.8%) than male (59, 44.0%). The study results revealed that 217(74.1%) vaccine recipients had side effects after first dose while 162(55.3%) had side effects on second dose of the Oxford-AstraZeneca vaccine. Commonly experienced side effects were pain in the injection site, fever, headache, diarrhoea and joint pain. Most of the people tolerated these side effects and did not use any medicine.

Abstract
Transcription factors (TF) are a wide class of genes in plants, and these can regulate the expression of other genes in response to various environmental stresses (biotic and abiotic). In the current study, transcription factor activity in sugarcane was examined during cold stress. Initially, RNA transcript reads of two sugarcane cultivars (ROC22 and GT08-1108) under cold stress were downloaded from SRA NCBI database. The reads were aligned into a reference genome and the differential expression analyses were performed with the R/Bioconductor edgeR package. Based on our analyses in the ROC22 cultivar, 963 TF genes were significantly upregulated under cold stress among a total of 5649 upregulated genes, while 293 TF genes were downregulated among a total of 3,289 downregulated genes. In the GT08-1108 cultivar, 974 TF genes were identified among 5,649 upregulated genes and 283 TF genes were found among 3,289 downregulated genes. Most transcription factors were annotated with GO categories related to protein binding, transcription factor binding, DNA-sequence-specific binding, transcription factor complex, transcription factor activity in RNA polymerase II, the activity of nucleic acid binding transcription factor, transcription corepressor activity, sequence-specific regulatory region, the activity of transcription factor of RNA polymerase II, transcription factor cofactor activity, transcription factor activity from plastid promoter, transcription factor activity from RNA polymerase I promoter, polymerase II and RNA polymerase III. The findings of above results will help to identify differentially expressed transcription factors during cold stress. It also provides a comprehensive analysis of the regulation of the transcription activity of many genes. Therefore, this study provides the molecular basis for improving cold tolerance in sugarcane and other economically important grasses.

Abstract
Medical education is associated with a great psychological distress that affects many aspects of students' lives, including their academic performance and professional development. The objective of the study was to determine the level of depression, anxiety and stress and their academic performance among fifth year medical students. This was a cross-sectional descriptive study conducted in Dhaka Medical College, Mymensingh Medical College, Anwar Khan Modern Medical College and Community Based Medical College of Bangladesh. For this purpose, 359 students were taken as sample and self-administered semi-structured questionnaire was used to collect data. Depression, anxiety and stress were assessed by using short form DASS-21 BV score. The results showed that, the mean age of students was 22.74 years with female predominance 230(64.0%). Majority 319(88.9%) of the respondents' parents monthly income was ≤100000 taka and one third 126(35.1%) respondents' monthly study expenditure was in between 5001 to 10000 taka. Four fifth 317(88.0%) of the respondents came from nuclear type of family and two third 245(68.2%) lived in hostel. Half 178(50.0%) of the respondents were eldest in birth order. Majority 221(61.6%) of the students were admitted to medical college by their own motivation and interest. Symptoms of depression, anxiety and stress were present in 179(49.9%), 215(59.9%) and 161(44.8%) respectively. No significant association was found between academic performance with depression or anxiety or stress, except class attendance of Gynaecology and Obstetrics which was significantly associated with stress (p=0.016); the students who suffered from more stress, their class attendance were very poor. Students who reappeared in MBBS professional examination were significantly associated with depression (p=0.032) and stress (p=0.036). There was significant difference between students of public and private medical colleges in terms of anxiety (p=0.031) that is students of public medical colleges more suffered from depression, anxiety and stress in comparison to private medical colleges. Depression (p=0.001) and anxiety (p=0.010) were significantly associated with motivation to study MBBS. No significant difference of depression, anxiety or stress was found with sex difference. This study revealed that fifth year MBBS students suffered more from depression, anxiety and stress. The causes of depression, anxiety and stress should be identified and resolved to improve their mental health and academic performance.

Abstract
Utilization of modern breeding techniques for developing high yielding and uniform plant types ultimately narrowing the genetic makeup of most crops. Narrowed genetic makeup of these crops has made them vulnerable towards disease and insect epidemics. For sustainable crop production, genetic variability of these crops must be broadened against various biotic and abiotic stresses. One of the ways to widen genetic configuration of these crops is to identify novel additional sources of durable resistance. In this regard crops wild relatives are providing valuable sources of allelic diversity towards various biotic, abiotic stress tolerance and quality components. For incorporating novel variability from wild relative's wide hybridization technique has become a promising breeding method. For this purpose, wheat-Th. bessarabicum amphiploid, addition and translocation lines have been screened in field and screen house conditions to get novel sources of yellow rust and Karnal bunt resistant. Stripe rust screening under field conditions has revealed addition lines 4JJ and 6JJ as resistant to moderately resistant while addition lines 3JJ, 5JJ, 7JJ and translocation lines Tr-3, Tr-6 as moderately resistant wheat-Thinopyrum-bessarabicum genetic stock. Karnal bunt screening depicted addition lines 5JJ and 4JJ as highly resistant genetic stock. These genetic stocks may be used to introgression novel stripe rust and Karnal bunt resistance from the tertiary gene pool into susceptible wheat backgrounds.

Abstract
For the proper growth of fish, it is necessary to feed the fish with a proper and balanced diet. A study was conducted to find out the effect of different protein-based diets on fingerlings of Tor putitora (mahseer). A feed with dietary protein levels of 35%, 40%, 45%, and 50% were prepared. The effect of different protein-based feed on weight gain, standard growth rate (SGR), food conversion ratio (FCR), percent weight gain, food conversion efficiency (FCE), and protein efficiency ratio (PER) was studied. An increase was observed in the growth rate with an increase in protein concentration up to 45%. The fingerlings fed a 45% protein diet shown the highest growth, followed by 50%, 40%, and 35%. The SGR value was greatest for 45% protein diet (8.56) followed by 50% and 40%, while the least values were observed for 35% protein feed (1.57). The same trend was observed for FCE. The highest PER values was observed in fishes fed 45% protein-based feed (0.65) followed by 50% (0.56), 40% (0.38) and35% (0.17). The food conversion ratio was lowest for 45% protein diet (3.41), while the greatest for 35% protein feed (16.85). It was concluded that a 45% protein-based diet was the best feed formulation for higher production of Tor putitora. However, research on the same percentage of protein diet is recommended for yearlings.

Abstract
Present study endeavored to evaluate the microbial contamination level along with their
drug resistant pattern in some popular desert food items collected from different food
shops in Dhaka city, Bangladesh. The microbial evaluation was conducted through
conventional cultural methods and drug susceptibility test was executed through disc
diffusion method. All the samples were found to be contaminated with heterotrophic
bacteria as well as fungi within the range of 103
to 105 CFU/g. In case of specific
microflora, the growth of Staphylococcus spp. was very high in sweet, faluda, milk cake
and ice cream as estimated up to 105 CFU/g, halua and sweet yogurt showed 104 CFU/g
while rest of the samples revealed 103 CFU/g. E. coli was found only in faluda and ice
cream up to 103 CFU/g whereas Klebsiella spp. was estimated in all the samples within the
range of 102 CFU/g to 105 CFU/g. Salmonella spp., Pseudomonas spp. and Bacillus spp.
were totally absent in all the samples. Most of the isolates were found to be resistant
against most of the antibiotics. Meanwhile, streptomycin (10 µg), gentamicin (10 µg),
azithromycin (15 µg), and nalidixic acid (5 µg) were effective drug against both E. coli
and Staphylococcus spp.

Abstract
Liver abscess is a serious, life threatening condition. A recent development in the management of liver abscesses, facilitated by advances in diagnostic and interventional radiology, has decreased mortality rates. The purpose of this study is to search for the clinical presentations and surgical outcomes of liver abscess in our country. The markers of the outcome are mortality, duration of hospital stay and complications such as wound infection, residual disease following surgery, biliary leakage, intra abdominal abscess formation. This observational cross sectional study was conducted in Mymensingh Medical College & Hospital (MMCH), Bangladesh for 12 months from 1st January 2017 to 31st December 2017. Total 25 patients presenting with the features of liver abscess were included in this study by convenient and purposive sampling according to the inclusion and exclusion criteria. Surgical principles of liver abscess management were applied and outcomes were observed. The patients were diagnosed on the basis of clinical feature, findings of abdominal ultrasound and occasionally by doing CT scan. Most of the patients (28%) were in the age group of 51-60 years. Regarding sex distribution majority of the patients (64%) was male. Most of patients presented with fever (92%), anorexia and vomiting (32%), upper abdominal pain (84%). Hepatomegaly and reactive pleural effusion are the important findings present in 9(36%) and 8(32%) patients respectively. Size of the liver abscess was more than 5cm in 72% patients. Among the patients right lobe was predominantly involved. It was found during laparotomy that 4 patients (16%) had spontaneous rupture of abscess into peritoneal cavity. One (4%) patient developed biliary leakage after surgical drainage. No intra abdominal abscess or residual diseases was observed after surgery. Among the patients 24% developed wound infection. The overall mortality rate was 12%. The median length of hospital stay was 8 days (range: 1-15 days). Outcome of surgical drainage of liver abscess in tertiary care hospital of our country shows satisfactory result. So, patients with large multiple liver abscess, septic shock, failures of percutaneous drainage should be treated by early open surgical intervention.

Abstract
AIMS To investigate the incidence and pattern of injury in patients with a diagnosis of a fall from a stairlift. METHODS Data was analysed from the Trauma Audit and Research Network (TARN) database from 2000 to 2018 for those recorded suffering stairlift related injuries between the ages of 40-100 years. Patient demographics, injury mechanism and pattern, mortality rate and height of fall were analysed. RESULTS 1069 patients were identified in the initial search with 651 having an eligible mechanism of injury. The mean age was 82 (range 41.4-100.1) years. The most common site of injury was the limbs (49.2%) with the most severe injuries to the head (mean AIS 3.1). The mean ISS was 12.5 (Range 1-75). There was no relationship between height of fall and ISS (rs 0.054 p = 0.4). Individuals were 78% more likely to have an ISS score of 15 or more if they had a head injury, (OR: 0.12; 95% CI: 0.06-0.24) and 79% more likely to have sustained an injury to the thorax (OR: 0.21; 95% CI: 0.11-0.41). Injury to the head was 95% more likely in individuals with an ISS score greater than 25 points or more (OR: 0.05; 95% CI: 0.01-0.16) and 69% more likely for those who sustain injury to the thorax. Individuals with an ISS score of 25 points or more were 18 times more likely to have sustained injury getting off their stair lift compared to any other method of falling from their stair lift. Mortality was associated with injuries to the thorax in those aged 70 years or below, injuries to the face, spine and limb for those aged 71-85 years and with head injury in those over 85 years. The overall mortality rate was 15.7%. CONCLUSION Falls from stairlifts commonly result in limb injuries and most severe injuries are sustained to the head. When patients fall getting off from astairlift, have injuries to their head or thorax they have a higher ISS. The overall mortality is 15.7%. Given the increasing use of stairlifts in our ageing population, strategies should be considered to make these safer.

Abstract
Pereinatal asphyxia is one of the most important complications related with the process of birth and this complications affect not only the brain but also many other organs. The purpose of this cross sectional study is to compare the role of craniosonogram and CT scan of the brain to delineate the cerebral pathology in respondent of preterm and term infant and to assess the Kappa test for agreement. This study was carried out in the department of Radiology & Imaging of Mymensingh Medical College Hospital, during the period of July 2015 to June 2017. A total number of 40 neonates clinically diagnosed as perinatal asphyxia referred for Craniosonogram and Computed tomography (CT) were included in this study. The test of agreement of USG in detection of neonatal cerebral pathology was calculated. Male to female ratio was 1:1.4. More than half (55.0%) patients were preterm age. The mean birth weight was found 2.3±0.6 kg and mean age was 22.7±12.7 days. Fifty five percent respondent mothers had antenatal check up and 27% had anemia, 11% had premature rupture of membrane, 9% had multiple pregnancy and 7% patient had hypertension. Cerebral pathology was found 28 and 31 cases by Craniosonogram and CT scan respectively. Germinal matrix hemorrhage/IVH (Intra ventricular hemorrhage) found 7(17.5%) in USG and 4(10.0%) in CT scan. Hypoxic ischaemic changes with mild ventriculomegaly observed 5(12.5%) in USG and 7(17.5%) in CT scan. Hypoxic ischaemic change found 4(10.0%) in USG and 5(12.5%) in CT scan. In USG evaluation of 28 patients having cerebral pathology & 16(72.7%) had in preterm group and 12(66.7%) in term group. In CT scan of brain 31 patients with cerebral pathology & 15(37.5%) in preterm group and 16(40.0%) in term group. CT scan found cerebral pathology 77.5% (31/40) cases and USG found 70.0% (28/40), with Kappa value was 0.551, which indicates that fair agreement between USG and CT scan for detection of cerebral pathology in respondent. Craniosonogram is a useful method in all neonates specially preterm to see the CNS complication of perinatal asphyxia.

Abstract
Sub clinical hypothyroidism (SCH) is common in clinical practice. Autoimmunity is thought to be the most important cause of SCH. In this cross-sectional study, we investigated 120 SCH patients and 100 healthy controls attending the Endocrinology Outpatient Department of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from June 2014 to April 2015 for anti-thyroid antibodies (anti-TPO and anti-Tg). Measurement of serum TSH, FT4, anti-TPO, and anti-Tg antibodies were done by using the chemiluminescent sequential immunometric assay. SCH patients had a higher mean age; the frequencies of female subjects, those having family history of thyroid disease or other autoimmune diseases, and goiter were higher in SCH group than in the control group. Forty-five percent (45%) of SCH patients were positive for anti-thyroid antibodies (23.3% for both anti-TPO and anti-Tg, 16.7% for only anti-TPO, and 5% positive for only anti-Tg) in comparison to only 10% anti-thyroid antibody positive controls (none for both antibodies, 8% for only anti-TPO, and 2% positive for only anti-Tg). The SCH subjects in the lower age group, females and with a TSH >10μIU/mL had the higher frequency of thyroid autoimmunity. Female gender, high socioeconomic condition, the presence of other autoimmune diseases, the presence of goiter and TSH >10μIU/mL were associated with higher odds of anti-thyroid antibody positivity in the SCH group, though none were statistically significant. The frequency of anti-thyroid antibody was higher in SCH and was more prevalent among the females, younger patients and those having a goiter, other autoimmune diseases, and TSH >10μIU/mL.

Abstract
ABA is important for plant growth and development; however, it also inhibits photosynthesis by regulating the stomatal aperture and ribulose-1,5-bisphosphate carboxylase/oxygenase activity. Noteworthy, this negative effect can be alleviated by antioxidants including ascorbic acid (AsA) and catalase (CAT), but the underlying mechanism remains unclear. Two rice cultivars, Zhefu802 (recurrent parent) and its near-isogenic line, fgl were selected and planted in a greenhouse with 30/24 °C (day/night) under natural sunlight conditions. Compared to fgl, Zhefu802 had significantly lower net photosynthetic rate (PN) and stomatal conductance (Cond) as well as significantly higher ABA and H2O2 contents. However, AsA and CAT increased PN, Cond, and stomatal aperture, which decreased H2O2 and malondialdehyde (MDA) levels. In this process, AsA and CAT significantly increased the ribulose-1,5-bisphosphate carboxylase activity, while they strongly decreased the ribulose-1,5-bisphosphate oxygenase activity, and finally caused an obvious decrease in the ratio of photorespiration (Pr) to PN. Additionally, AsA and CAT significantly increased the expression levels of RbcS and RbcL genes of leaves, while H2O2 significantly decreased them, especially the RbcS gene. In summary, the removal of H2O2 by AsA and CAT can improve the leaf photosynthesis by alleviating the inhibition on the stomatal conductance and ribulose-1,5-bisphosphate carboxylase capacity caused by ABA.

Abstract
Global population is ageing and Bangladesh has one of the fastest growing ageing populations in this region. Growth in the elderly population relative to other age groups challenges existing health services, family relationships and social security. Combined with this, depression has become a major mental health problem for elderly people especially for urban elderly for nuclear family norm in urban areas. The study was descriptive type of cross-sectional in nature and was conducted in Rangpur Medical College Hospital, Rangpur & Prime Medical College Hospital, Rangpur, Bangladesh. The objective of this study was to assess the lifestyle and level of depression in urban elderly. Depression was measured by questionnaire of geriatric depression scale among 254 respondents. 87.8% of the respondents were age between 60-70 years. Majorities (63%) of the respondents were male, 54% of the respondents lived in nuclear type family and the rest (46%) in joint type of family. Among respondents near half (47.2%) of the respondents found Mild depressive, around one third (32.7%) were severe depressive, and the rest (20.1%) were normal. There was significant association between occupational status of the respondents and depression (x² = 45.600, df=14, p=0.000). Farmers unemployed found severely depressive (52.1%) followed by day-labourer (50%) and businessmen (37.5%). There was significant association between financial self dependency and depression of the respondents (x²= 34.072, df=4, p=0.000). Severe depression (43.8%) was found among those who were not financially self dependent. There was also significant association between monthly income and depression of the respondents (x²= 67.327, df=8, p=0.000). The study also found that lower income group (<Tk 10000) suffer more from severe depression (42.1% vs. 16.67%) than that of higher income group (Tk 50000-99999). Another significant association found between respondents living with family and depression (x²=16.025, df=2, P=0.000). Respondents those not living with family were suffering more from severe depression (55.55%). Association between social activity and depression (x²=31.724, df=4, p=0.000) revealed that those not involved in social activities were in severe depression (40.55%). The study concluded that lifestyle factors and socio-demographic conditions directly influence the state of depression. Those who lead a healthy social life with friends and family, with a stable income source are less prone to severe depression and vice versa. The study recommended the formulation of strategies for the well being of urban elderly that should include social awareness about positive lifestyle changes, social mobilization, health assurance, and response from the government so that depression and its associated serious diseases can be prevented.

Abstract
Liver cancer is associated with genetic mutations caused by environmental exposures, including occupational exposure to alpha radiation emitted by plutonium. We used whole exome sequencing (WES) to characterize somatic mutations in 3 histologically distinct primary liver tumors (angiosarcoma of the liver (ASL), cholangiocarcinoma (CCA) and hepatocellular carcinoma (HCC)) from Mayak worker subjects occupationally exposed to ionizing radiation (IR) to investigate the contribution of IR to the mutational landscape of liver cancer. DNA sequence analysis revealed these tumors harbor an excess of deletions, with a deletions:substitutions ratio similar to that previously reported in radiation-associated tumors. These tumors were also enriched for clustered mutations, a signature of radiation exposure. Multiple tumors displayed similarities in abrogated gene pathways including actin cytoskeletal signaling and DNA double-strand break (DSB) repair. WES identified novel candidate driver genes in ASL involved in angiogenesis and PIK3CA/AKT/mTOR signaling. We confirmed known driver genes of CCA, and identified candidate driver genes involved in chromatin remodeling. In HCC tumors we validated known driver genes, and identified novel putative driver genes involved in Wnt/β-catenin signaling, chromatin remodeling, PIK3CA/AKT/mTOR signaling, and angiogenesis. This pilot study identifies several novel candidate driver mutations that are likely to be caused by IR exposure, and provides the first data on the mutational landscape of liver cancer after IR exposure.
