Abstract
The present study was designed to construct an anthropometric data of 20-40 years aged 104 Bangladeshi Garo people (60 male and 44 female) regarding carrying angle and an attempt has been made out to grow interest among the researchers for future study and also to compare the data with the data of the people of other races. Participants were selected through purposive sampling for this cross sectional, observational, descriptive and analytic type study which was carried out in different areas of Mymensingh district (Haluaghat, Mymensingh Sadar), Bangladesh from July 2015 to June 2016. The carrying angles of both side were measured by goniometer. Data were tabulated and statistically analyzed using Microsoft excel and SPSS software. Carrying angle was found to be higher in males but angle of inclination was higher in females. Comparison of differences of means between male and female was statistically significant. The results of present study would be useful for Anthropologist and Forensic Medicine experts.

Abstract
A 25 years married women having one child delivered vaginaly presented in the department of Obs & Gynae, Bangabandhu Sheikh Mujib Medical University, Bangladesh on April 2013 with pelvic pain and discomfort. No history of previous pelvic trauma was present. Patient examination showed a isolated mass in the right lower abdomen, right adnexa, extending to the pelvic wall upto lower end of ureter. Tumor markers were within normal limit. Intravenous pyelogram (IVP) showed mild right hydroureter and hydronephrosis with obstruction at the lower end of ureter. She was diagnosed as a case of adnexal mass with mild hydroureter & mild hydronephrosis and it was decided to operate on the patient. The surgical approach was transabdominal. On laparotomy a pseudocystic lesion 12×10cm in size was found over the right paracolic gutter and extending down into the pelvis involving the right parametrium. No abnormality was found in the uterus or tubes. The histological examination revealed a desmoid tumor of the pelvis. The patient's recovery was uneventful.

Abstract
TAM (Tyro3-Axl-Mer) receptor tyrosine kinases and Met are implicated in several hallmarks of cancer progression including sustained angiogenesis, enhanced motility, tissue invasion and acquisition of metastatic potential through the upregulation of epithelial-to-mesenchymal transition. Increasing evidence has confirmed Axl and Met as emerging central drivers of adaptive resistance to targeted therapies across a wide variety of cancers. In this issue of Oncogene, Zhou et al. describe the mechanisms linking Axl and Met activation to acquired resistance to sunitinib in renal cell carcinoma (RCC), providing a pre-clinical rationale for the development of Axl and Met inhibitors including cabozantinib in anti-angiogenic resistant RCC.

Abstract
Sirtuins are a family of protein deacylases related by amino acid sequence and cellular function to the yeast Saccharomyces cerevisiae protein Sir2 (Silent Information Regulator-2), the first of this class of enzymes to be identified and studied in detail. Based on its initially discovered activity, Sir2 was classified as a histone deacetylase that removes acetyl groups from histones H3 and H4. The acetylation/deacetylation of these particular substrates leads to changes in transcriptional silencing at specific loci in the yeast genome, hence its name. Sirtuins, however, have been shown to regulate a wide variety of cellular processes beyond transcriptional repression in varied subcellular compartments and in different cell types. Mechanistically distinct from Zn(2+)-dependent deacylases, sirtuins use nicotinamide adenine dinucleotide as a cofactor in the removal of acetyl and other acyl groups linking metabolic status and posttranslational modification. Sirtuins' unique position has made them attractive targets for small-molecule drug development. In this chapter, we describe the biological roles, therapeutic areas in which sirtuins may play a role and development of small-molecule inhibitors of sirtuins employing phenotypic screening technologies ranging from assays in yeast, as well as biochemical screens to yield lead drug development candidates targeting a broad spectrum of human diseases.

Abstract
BACKGROUND Preclinical work suggests SRC proteins have a role in the development of resistance to vascular endothelial growth factor (VEGF) targeted therapy in metastatic clear-cell renal cancer (mRCC). This hypothesis was tested in this trial using the SRC inhibitor saracatinib and the VEGF inhibitor cediranib. PATIENTS AND METHODS Patients with disease progression after ≥1 VEGF-targeted therapy were eligible to participate in this double-blind, randomized (1:1) phase II study. The study compared the combination cediranib 30 mg once daily (o.d.) and saracatinib 175 mg o.d. (CS) (n = 69) or cediranib 45 mg o.d. and placebo o.d. (C) (n = 69). Archived tissue was used for biomarker analysis [SRC, focal adhesion kinase (FAK), von Hippel-Lindau, protein tyrosine phosphatase 1b and hypoxia-inducible factor 2α : n = 86]. The primary end point was progression-free survival (PFS) by RECIST v1.1. RESULTS Between 2010 and 2012, 138 patients were randomized across 16 UK sites. The characteristics of the two groups were well balanced. Partial responses were seen in 13.0% for C and 14.5% for CS (P > 0.05). There was no significant difference in PFS [5.4 months (3.6-7.3 months) for C and 3.9 (2.4-5.3 months) for CS; hazard ratio (HR) 1.18 (0.94-1.48)] or overall survival (OS) [14.2 months (11.2-16.8 months) for C and 10.0 (6.7-13.2 months) for CS; HR 1.28 (1.00-1.63)]. There was no significant difference in the frequency of key adverse events, dose reductions or drug discontinuations. None of the biomarkers were prognostic for PFS or OS. FAK overexpression correlated with an OS benefit [HR 2.29 (1.09-4.82), P > 0.05], but not PFS, for CS. CONCLUSIONS Saracatinib did not increase the efficacy of a VEGF-targeted therapy (cediranib) in this setting. Biomarker analysis did not identify consistent predictive biomarkers. CLINICALTRIALSGOV NCT00942877.

Abstract
Mutation in the TP53 gene positively correlates with increased incidence of chemoresistance in different cancers. In this study, we investigated the mechanism of chemoresistance and epithelial-to-mesenchymal transition (EMT) in colorectal cancer involving the gain-of-function (GOF) mutant p53/ephrin-B2 signaling axis. Bioinformatic analysis of the NCI-60 data set and subsequent hub prediction identified EFNB2 as a possible GOF mutant p53 target gene, responsible for chemoresistance. We show that the mutant p53-NF-Y complex transcriptionally upregulates EFNB2 expression in response to DNA damage. Moreover, the acetylated form of mutant p53 protein is recruited on the EFNB2 promoter and positively regulates its expression in conjunction with coactivator p300. In vitro cell line and in vivo nude mice data show that EFNB2 silencing restores chemosensitivity in mutant p53-harboring tumors. In addition, we observed high expression of EFNB2 in patients having neoadjuvant non-responder colorectal carcinoma compared with those having responder version of the disease. In the course of deciphering the drug resistance mechanism, we also show that ephrin-B2 reverse signaling induces ABCG2 expression after drug treatment that involves JNK-c-Jun signaling in mutant p53 cells. Moreover, 5-fluorouracil-induced ephrin-B2 reverse signaling promotes tumorigenesis through the Src-ERK pathway, and drives EMT via the Src-FAK pathway. We thus conclude that targeting ephrin-B2 might enhance the therapeutic potential of DNA-damaging chemotherapeutic agents in mutant p53-bearing human tumors.

Abstract
Hypothyroidism is one of the most common endocrine disorders encountered in clinical practice. Thyroid disorder is very common among the female. The aim of this study was to evaluate the effects of hypothyroidism on menstrual pattern and sub-fertility. This cross-sectional comparative study was carried out in the Department of Obstetrics and Gynecology with collaboration of endocrine department of Bangabandhu Sheikh Mujib Medical University (BSMMU) from July 2006 to June 2008, cases were collected from the thyroid clinic of this hospital. Total study subject were 139, among them hypothyroid cases were 79 and euthyroid were 60. Among the hypothyroidism group 62.0% (n=49) had normal menstrual cycle, 21.5% (n=16) had oligomenorrhoea, 10.1% (n=8) had polymenorrhoea and 6.3% (n=6) had amenorrhoea. On the contrary in euthyroid group 86.7% (n=52) had normal menstrual cycle, 6.7% (n=4) had oligomenorrhoea, 5.0% (n=3) had polymenorrhoea and 1.7% (n=1) had amenorrhoea. Proportion of abnormal menstrual history was found to high among hypothyroid group almost 34% (n=27) compared to euthyroid group 13.4% (n=8) and the difference was statistically significant (p<0.001). The proportion of primary subfertility in hypothyroid 11.4% (n=9) whereas in euthyroid cases 1.7% (n=1) and secondary subfertility in hypothyroid 7.6% (n=6) where as in euthyroid cases 5.0% (n=3). So, sub-fertility was higher among hypothyroid group compared to euthyroid group but the difference was not statistically significant (p>0.05). Overall sub-fertility was 13.7% (n=10) and it was 6.7% (n=4) among the euthyroid group. Among total hypothyroid group 60.7% (n=48) are the overt hypothyroid and 39.20% (n=31) are the sub-clinical hypothyroid group. The effect of hypothyroidism is significant on menstrual pattern and on fertility. Hypothyroid women had more menstrual disorders and also suffering from sub-fertility.

Abstract
Disability adjusted life years (DALY) is the sum of the present value of future years of lifetime lost through premature mortality, and the present value of years of future life-time adjusted for the average severity of any mental or physical disability caused by a disease or injury. As a method for estimating the global burden of disease, DALY was first introduced in the World Development Report in 1993 by the World Bank. The aim of this study was to estimate DALY among arsenicosis patients. DALY was calculated for 104 arsenicosis patients from an arsenic-affected rural area of southern Bangladesh using the estimated years they lived with disability (YLD). The mean (SD) of cumulative arsenic exposure level was 5.0 (3.2) mg/l-years. Among the patients, 64% reported reduction in working ability. The portion of the patients with disability for more than 50 years was as high as 58.7%. The mean (SD) of YLD and DALY was 54.0 (9.8) and 9.2 (1.5), respectively. A total of 5621 YLD equivalent to 961.7 DALY was lost due to arsenicosis (when life expectancy at birth according to Bangladesh Bureau of Statistics was applied, the YLD and DALY were 3899.2 and 868.9, respectively). There was significant relationship of YLD with education of the patients (p < 0.05). There was significant relationship between DALY and education of the patients (p < 0.05). There was also significant relationship between DALY and reduction in working ability of the patients (p < 0.05). The findings of the study justify for the policy makers to adopt adequate measures such as prevention, treatment and rehabilitation to alleviate the sufferings of the arsenicosis patients.Mediscope Vol. 2, No. 1: 2015, Pages 4-12

Abstract
Mullerian anomalies are a relatively uncommon occurrence with implication for adolescents and adults as they may result in specific gynaecologic, fertility and obstetrical issues. Uterus didelphys with blind hemivagina and ipsilateral renal agenesis is a rare congenital anomaly. Patient may be asymptomatic and unaware of having double uterus or may present with severe dysmenorrhoea or dyspareunia or a palpable mass due to unilateral haematocolpos. We report a case of 12 year old girl with this condition who was diagnosed as uterus didelphys with unilateral haematocolpos with ipsilateral renal agenesis on the basis of clinical association, physical examination and sonography and intravenous urogram.

Abstract
BACKGROUND Asthma and atopy share common characteristics including type 2 helper-T-cell-mediated inflammation. However, only asthma is associated with variable airways obstruction. The complex cellular and molecular pathways distinguishing asthma and atopy can now be captured by transcriptomic analysis (RNA-Seq). We hypothesized that the transcriptomic profile of airway smooth muscle (ASM) distinguishes atopic asthma from atopic healthy controls. First, we compared the ASM transcriptomic profiles of endobronchial biopsies between glucocorticoid-free, atopic asthma patients, and atopic and nonatopic healthy controls. Second, we investigated the association between ASM transcriptomic profiles and airway function. METHODS Twelve asthma patients and 12 control subjects (six atopic, six nonatopic) underwent bronchoscopy. RNA of laser-dissected ASM from 96 bronchial biopsy specimens was sequenced with Roche GS FLX. Gene networks were identified using Ingenuity Pathway Analysis. RNA-Seq reads were assumed to follow a negative binomial distribution. With the current sample size, the estimated false discovery rate was approximately 1%. RESULTS One hundred and seventy four ASM genes were differentially expressed between asthma patients and atopic controls, 108 between asthma patients and nonatopic controls, and 135 between atopic and nonatopic controls. A set of eight genes discriminated asthma patients from nonasthmatic controls, irrespective of atopy. Four of these genes (RPTOR, VANGL1, FAM129A, LEPREL1) were associated with airway hyper-responsiveness (P < 0.05). CONCLUSION Airway smooth muscle from asthma patients can be distinguished from that of atopic and nonatopic control subjects by a specific gene expression profile, which is associated with airway hyper-responsiveness.

Abstract
In this study, Wood Ash (WA) prepared from the uncontrolled burning of the saw dust is evaluated for its suitability as partial cement replacement in conventional concrete. The saw dust has been acquired from a wood polishing unit. The physical, chemical and mineralogical characteristics of WA is presented and analyzed. The strength parameters (compressive strength, split tensile strength and flexural strength) of concrete with blended WA cement are evaluated and studied. Two different water-to-binder ratio (0.4 and 0.45) and five different replacement percentages of WA (5%, 10%, 15%, 18% and 20%) including control specimens for both water-to-cement ratio is considered. Results of compressive strength, split tensile strength and flexural strength showed that the strength properties of concrete mixture decreased marginally with increase in wood ash contents, but strength increased with later age. The XRD test results and chemical analysis of WA showed that it contains amorphous silica and thus can be used as cement replacing material. Through the analysis of results obtained in this study, it was concluded that WA could be blended with cement without adversely affecting the strength properties of concrete. Also using a new statistical theory of the Support Vector Machine (SVM), strength parameters were predicted by developing a suitable model and as a result, the application of soft computing in structural engineering has been successfully presented in this research paper.

Abstract
BACKGROUND In 2010 the World Health Assembly called for action to improve the care and prevention of congenital disorders, noting that technical guidance would be required for this task, especially in low- and middle-income countries. Responding to this call, we have developed a freely available web-accessible Toolkit for assessing health needs for congenital disorders. METHODS Materials for the Toolkit website (http://toolkit.phgfoundation.org) were prepared by an iterative process of writing, discussion and modification by the project team, with advice from external experts. A customized database was developed using epidemiological, demographic, socio-economic and health-services data from a range of validated sources. Document-processing and data integration software combines data from the database with a template to generate topic- and country-specific Calculator documents for quantitative analysis. RESULTS The Toolkit guides users through selection of topics (including both clinical conditions and relevant health services), assembly and evaluation of qualitative and quantitative information, assessment of the potential effects of selected interventions, and planning and prioritization of actions to reduce the risk or prevalence of congenital disorders. CONCLUSIONS The Toolkit enables users without epidemiological or public health expertise to undertake health needs assessment as a prerequisite for strategic planning in relation to congenital disorders in their country or region.

Abstract
BACKGROUND The identification of common genetic variants associated with common cancers including breast, prostate and ovarian cancers would allow population stratification by genotype to effectively target screening and treatment. As scientific, clinical and economic evidence mounts there will be increasing pressure for risk-stratified screening programmes to be implemented. METHODS This paper reviews some of the main ethical, legal and social issues (ELSI) raised by the introduction of genotyping into risk-stratified screening programmes, in terms of Beauchamp and Childress's four principles of biomedical ethics--respect for autonomy, non-maleficence, beneficence and justice. Two alternative approaches to data collection, storage, communication and consent are used to exemplify the ELSI issues that are likely to be raised. RESULTS Ultimately, the provision of risk-stratified screening using genotyping raises fundamental questions about respective roles of individuals, healthcare providers and the state in organizing or mandating such programmes, and the principles, which underpin their provision, particularly the requirement for distributive justice. CONCLUSIONS The scope and breadth of these issues suggest that ELSI relating to risk-stratified screening will become increasingly important for policy-makers, healthcare professionals and a wide diversity of stakeholders.

Abstract
BACKGROUND Current imaging criteria for categorising disease response in metastatic renal cell carcinoma (mRCC) correlate poorly with overall survival (OS) in patients on anti-angiogenic therapies. We prospectively assess diffusion-weighted and multiphase contrast-enhanced (MCE) MR imaging (MRI) as markers of outcome. METHODS Treatment-naive mRCC patients on a phase II trial using sunitinib completed an MRI substudy. Whole-tumour apparent diffusion coefficient (ADC) maps and histograms were generated, and mean ADC and AUC(low) (proportion of the tumour with ADC values lying below the 25th percentile of the ADC histogram) recorded. On MCE-MRI, regions of interest were drawn around the most avidly enhancing components to analyse enhancement parameters. Baseline (n=26) and treatment-related changes in surviving patients (n=20) were correlated with OS. Imaged metastases were also analysed. RESULTS Forty-seven per cent of the patients showed significant changes in whole-tumour mean ADC following therapy, but there was no correlation with outcome. Patients with a high baseline AUC(low) and greater-than-median AUC(low) increase had reduced OS (HR=3.67 (95% confidence interval (CI)=1.23-10.9), P=0.012 and HR=3.72 (95% CI=0.98-14.21), P=0.038, respectively). There was no correlation between MCE-MRI parameters and OS. Twenty-eight metastases were analysed and showed positive correlation with primary tumour mean ADC for individual patients (r=0.607; P<0.001). CONCLUSION Primary RCC ADC histogram analysis shows dynamic changes with sunitinib. Patients in whom the tumour ADC histogram demonstrated high baseline AUC(low) or a greater-than-median increase in AUC(low) with treatment had reduced OS.

Abstract
Using the principles of public health genomics, we examined the opportunities and challenges of implementing personalized prevention programmes for cancer at the population level. Our model-based estimates indicate that polygenic risk stratification can potentially improve the effectiveness and cost-effectiveness of screening programmes. However, compared with 'one-size-fits-all' screening programmes, personalized screening adds further layers of complexity to the organization of screening services and raises ethical, legal and social challenges. Before polygenic inheritance is translated into population screening strategy, evidence from empirical research and engagement with and education of the public and the health professionals are needed.

Abstract
The objectives of this study were to assess the socio-demographic 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 and Gynaecology department of Ad-din Women Medical College Hospital from 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 socio-demographic characteristics and maternal-fetal risk factors were evaluated with a semi structured questionnaire which was pre-tested before executing in this study. 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 secondary school certificate (SSC) level and 28.91% took regular antenatal checkup. About 61.45% patients were multi-gravida. 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 ante-partum deaths.

Abstract
BACKGROUND The new generation anti-androgen enzalutamide and the potent CYP17 inhibitor abiraterone have both demonstrated survival benefits in patients with metastatic castration-resistant prostate cancer (CRPC) progressing after docetaxel. Preliminary data on the antitumour activity of abiraterone after enzalutamide have suggested limited activity. The antitumour activity and safety of enzalutamide after abiraterone in metastatic CRPC patients is still unknown. PATIENTS AND METHODS We retrospectively identified patients treated with docetaxel and abiraterone prior to enzalutamide to investigate the activity and safety of enzalutamide in a more advanced setting. Prostate specific antigen (PSA), radiological and clinical assessments were analysed. RESULTS 39 patients with metastatic CRPC were identified for this analysis (median age 70years, range: 54-85years). Overall 16 patients (41%) had a confirmed PSA decline of at least 30%. Confirmed PSA declines of ⩾50% and ⩾90% were achieved in 5/39 (12.8%) and 1/39 (2.5%) respectively. Of the 15 patients who responded to abiraterone, two (13.3%) also had a confirmed ⩾50% PSA decline on subsequent enzalutamide. Among the 22 abiraterone-refractory patients, two (9%) achieved a confirmed ⩾50% PSA decline on enzalutamide. CONCLUSION Our preliminary case series data suggest limited activity of enzalutamide in the post-docetaxel and post-abiraterone patient population.

Abstract
Central giant cell granuloma (CGCG) is a benign, non-odontogenic bone lesion of jaw. The condition is relatively infrequent and affects mainly children and young adults with a certain predominance among females and exhibits variable aggressiveness. Giant cell lesion associated with hyperparathyroidism is known as Brown tumor. Brown tumor is one of the bony complications of hyperparathyroidism. It is a giant cell granuloma which occurs in osteitis fibrosis cystica. It represents the terminal stage of the bone remodelling processes occurring as a result of peritrabecular fibrosis and osteoclastic activity. The mandible is the predominantly affected site in the maxillofacial area. Maxillary involvement is rare. The incidence of Brown tumor associated with hyperparathyroidism is rare (0.1%). Here, an extremely rare case of a 20 year old female patient with Brown tumor in her maxilla and mandible associated with primary hyperparathyroidism was presented. A thorough diagnostic work up showed presence of tumor mass in mandible and maxilla and elevated serum alkaline phosphatase and parathormone level and the patient was treated for both hyperparathyroidism and Brown tumor were discussed. The importance of different radiological evaluation methods and the consultation between the oral and maxillofacial surgeons, dentists, endocrinologists and radiologists were emphasized.

Abstract
BACKGROUND Improving understanding of the genetic basis of disease susceptibility enables us to estimate individuals' risk of developing cancer and offer them disease prevention, including screening, stratified to reflect that risk. Little attention has so far been given to the implementation of stratified screening. This article reviews the issues that would arise in delivering such tailored approaches to prevention in practice. RESULTS Issues analysed include the organisational context within which implementation of stratified prevention would occur, how the offer of screening would be made, making sure consent is adequately informed, how individuals' risk would be assessed, the age at which risk estimation should occur, and the potential use of genetic data for other purposes. The review also considers how management might differ depending on individuals' risk, how their results would be communicated and their follow-up arranged, and the different issues raised by modification of an existing screening programme, such as that for breast cancer, and the establishment of a new one, for example for prostate cancer. CONCLUSION Stratified screening based on genetic testing is a radically new approach to prevention. Various organisational issues would need to be considered before it could be introduced, and a number of questions require further research.
