Abstract
Gastric cancer (GC) is one of the most common tumors and remains the second leading cause of cancer mortality in the world. The incidence of gastric carcinoma is declining in the last few years in some areas like USA, UK, Canada etc, because of reduction in chronic H. pylori infection, smoking, decrease use of smoked and salted food. The gastric carcinoma still remains a burden for Bangladesh as the prevalence of H. Pylori has not substantially decreases. Among the gastric carcinomas, adenocarcinomas are the most common type. So the study was performed to observe the location and histomorphologic pattern of Gastric and gastrooesophageal junction (GEJ) adenocarcinoma. This descriptive cross sectional study was carried out at the Department of Pathology, Dhaka Medical College, Dhaka, Bangladesh from January 2013 to December 2014. A total of 130 patients with primary gastric and GEJ adenocarcinomas were included in this study. All the cases were evaluated for routine histological examination. The age range of the patients was 17 to 80 years and male to female ratio was 2.25:1. Antrum is the most common (66.9%) site being affected, followed by GEJ (19.2%), body (13%) and fundus (0.76%). Tumors of the antrum and GEJ were found mostly in the late age. On macroscopic examination, the ulcerated tumor mass (69.2%) was most frequent then the others. Regarding histological examination, 84(64.6%) cases were intestinal type, 32(24.6%) diffuse and 14(10.8%) mixed type by Laurens classification. According to WHO classification, about half of the cases (49.2%) were tubular carcinoma and rest were others. Most of the intestinal type carcinoma (71.4%) was presented with moderately differentiated and 25.0% with well differentiated. Where as the diffuse type presented with poorly differentiated in 96.9% cases.

Abstract
A total of 198 exotic barley genotypes were collected from the Gene Bank of the Plant Genetic Resource Institute (PGRI), National Agriculture Research Center (NARC), Islamabad, Pakistan, for the assessment of genetic diversity based on morphological and seed storage proteins. Qualitative and quantitative traits were noted as per IPGRI, 1994 descriptor. Among the quantitative parameters, a high level of genetic variability index was noted in seeds per spike at 79.9% of coefficient of variance followed by biomass per plant which shows 37.4% variance, while minimum variance in quantitative traits was noted in days to germination at 5.4% followed by days to maturity at 3.1% with average mean genetic variation in all quantitative traits at 97.6%. Assay of total seed protein in these exotic accessions was analogue through polyacrylamide gel electrophoresis. A high level of variation was noted in loci (bands) B26 (0.98%) followed by B25 (0.89%), B24 (0.78%),B23 (0.69%) and B01 (0.52%). A similarly low level of variation was detected in B03 (0.16%) followed by B06 (0.18%), B13 (0.19%), B12 (0.21%), B11 (0.23%), B05 (0.24%), B07 (0.25%), B21 (0.34%), B20 (0.35%), B17 (0.39%). The results indicate that the mean value of variation in these accessions is 97.6%. Further assessments and exploration were suggested for these genotypes in multi-climatic zones to satisfy farmers’ need, breeders’ interest and malt-industrial requirements.

Abstract
Abstract
Background
Recent research has revealed that reparative (alternatively activated or M2-like) macrophages play an important role in post-myocardial infarction (MI) cardiac repair, proposing that augmentation of these cells will enhance recovery from MI. Transplantation of bone marrow mononuclear cells (BM-MNCs) is an emerging therapy for MI while its therapeutic efficacy in previous clinical trials is not satisfactory. Given that BM-MNCs are a natural source of macrophages, we hypothesized that induced differentiation/polarisation of BM-MNCs to reparative macrophages before transplantation may enhance the effect of BM-MNC transplantation.
Purpose
This study aimed to develop a robust in vitro protocol to produce reparative macrophages from BM-MNCs and to establish the pre-clinical proof of concept data for reparative macrophage transplantation for the treatment of MI.
Methods and results
Mouse BM-MNCs were treated with M-CSF plus IL-4, IL-10, TGF-β1 or combinations of these in vitro. The concomitant M-CSF+IL-4 protocol (both 20ng/ml) produced the highest rate (89.7±0.7%) and number (1.7-fold larger than the original cell number) of CD11b+F4/80+CD206+ macrophages. Expression and secretion of tissue repair-related factors of the produced cells, including IGF-1, TGF-β1, VEGF and IL1-ra, were more extensive compared to BM-MNCs. Then, 5x105 BM-MNC-derived reparative macrophages, 5x105 BM-MNCs, or saline only (control) were intramyocardially injected in a mouse MI model based on coronary artery ligation. At 4 weeks after treatment, echocardiography demonstrated that reparative macrophage transplantation markedly improved cardiac function (left ventricular ejection fraction; 57.2±1.6%, n=11) compared to both BM-MNC transplantation (48.4±1.3%, n=9) and control group (44.4±2.0%, n=9). Histological studies showed that infarct size was the smallest after reparative macrophage transplantation in association with the greatest tissue repair in the peri-infarct myocardium, including augmented microvascular formation, reduced cardiomyocyte hypertrophy and reduced pathological interstitial fibrosis. These were corresponded to amplified myocardial upregulation of tissue repair-related genes. Of note, survival of donor reparative macrophages in the heart post-transplantation was >10-fold greater compared to BM-MNCs. It was also found that reparative macrophage transplantation increased host-derived cardiac reparative macrophages. This might be a part of the mechanism by which reparative macrophage transplantation augmented myocardial repair, and our in vitro antibody neutralisation study indicated that TGF-β1 played a role in this donor macrophage-to-host macrophage pathway.
Conclusion
M-CSF+IL-4 treatment was effective in producing reparative macrophages from BM-MNCs in vitro. Addition of this pre-treatment improved the therapeutic effect of BM-MNC transplantation. Further pre-clinical and clinical development of this advanced cell therapy is warrantied.

Abstract
Abstract
Objective
Assessing daily activities is important for understanding how cognitive abilities affect everyday functioning. We evaluated a new measure capturing engagement in cognitively-demanding activities among people with and without HIV, and examined associations with neurocognitive test performance and perceived cognitive difficulties.
Method
Participants included 79 adults (59 HIV+, 20 HIV-) enrolled in studies at UCSD (mean age = 55.1; SD = 13.1). Domain-specific composite scaled scores measured neurocognitive functioning as continuous variables. Demographically-corrected global deficit scores determined neurocognitive impairment. Perceived cognitive difficulties were self-reported via the Everyday Cognition scale (ECog). The newly created, self-report Frequency and Difficulty of Activities Scale (FDAS) measured frequency of engagement in 27 cognitively-demanding activities [0 = Never to 10 = Once a day or more] in the last month. FDAS “total frequency score” sums all frequency ratings. Participants also rated difficulty performing each FDAS activity [0 = Not at all to 10 = Extremely]. FDAS “difficult-activity score” sums frequency ratings only for activities that participants identified as difficult for them (i.e., difficulty rating >75th percentile of sample).
Results
Higher FDAS total frequency scores correlated with better verbal fluency (r = 0.26, p = 0.019) and processing speed (r = 0.24, p = 0.030). Multiple regression revealed a significant interaction between cognitive impairment and frequency of engagement in difficult activities (b = 0.34, 95%CI = 0.18-0.50, p < 0.001), such that higher FDAS difficult-activity scores related to more perceived cognitive difficulties only among cognitively impaired participants.
Conclusion
This study explored use of a new measure of complex daily activities to aid neuropsychological interpretation. Results suggest that effects of neurocognitive impairment on perceived cognitive difficulties may only be apparent if individuals are attempting to perform challenging everyday tasks.

Abstract
Abstract
HIV disproportionately affects Black and Latino people in the United States, but data on longitudinal neurocognitive patterns for these groups are scarce. This study evaluated the incidence and predictors of neurocognitive decline by ethnicity/race in a cohort of Black, Latino, and White people living with HIV (PLWH). Participants included 499 PLWH (43.5% White, 42.7% Black, 13.8% Latino; mean age at baseline = 43.5) from the six-site CNS HIV Anti-Retroviral Therapy Effects Research (CHARTER) study. Participants completed comprehensive neurocognitive and neuromedical evaluations over 3-7 study visits for an average of 2.8 years (SD = 1.1). Interpertation of neurocognitive change was based on published methods using regression-based norms that correct for baseline performance and practice effects. Survival analyses investigated the relationship between ethnicity/race and neurocognitive change, and predictors of neurocognitive decline. In follow-up, 108 participants (21.6%) declined, 311 (62.3%) remained stable, and 80 (16.0%) improved. In Cox proportional hazard models, hazard ratios for neurocognitive decline were increased for Latinos compared to Whites (HR = 2.19, 95%CI = 1.32-3.63, p = .002) and Blacks (HR = 1.87, 95%CI = 1.14-3.04, p = .01). Including significant covariates (baseline nadir CD4, hepatitis C Virus, and VACS Index: a composite marker of physical health among PLWH)did not significantly decrease the elevated risk for decline among Latinos. We found that Latino PLWH appear to have higher risk of neurocognitive decline compared to White and Black PLWH. Traditional markers of HIV disease and physical health at baseline did not explain this elevated risk of neurocognitive decline. Future research examining economic, socio-environmental, and culturally-relevant biomedical factors may help to explain this observed ethnic/racial disparity in longitudinal neurocognitive function in HIV.

Abstract
Abstract
Objective
With over 37 million Spanish-speakers, the US is the second country in the world with the largest number of Spanish-speakers. Identification of neurological dysfunction via neuropsychological testing for this language group requires knowledgeable application of available tests and normative data. Accordingly, we investigated whether rates of neurocognitive impairment (NCI) varied based on the Spanish language normative method used.
Method
Participants included 254 healthy native Spanish-speakers (Age: M = 37.3, SD = 10.4; Education: M = 10.7, SD = 4.3; 59% Female; 78.7% of known Mexican origin/descent) living in the US-Mexico border region. Participants completed the Hopkins Verbal Learning Test-Revised (HVLT-R), Trail Making Test (TMT) A&B, and Animal Naming in Spanish. Raw test scores were converted to demographically-adjusted T-scores based on normative adjustments developed for this population (Neuropsychological Norms for the US-Mexico Border Region in Spanish [NP-NUMBRS]) and norms developed based on samples in Mexico (Latin American Norms from Mexico [LAN-M] and NEUROPSI). Rates of NCI (T < 40) based on the different normative methods were compared via McNemar’s tests.
Results
Rates of NCI for NP-NUMBRS and NEUROPSI fell between the expected 15-17%. Compared to NP-NUMBRS, significantly lower rates were found when applying LAN-M for HVLT-R Total (4%) and Delayed Recall (8%), TMT-A (1%), and Animal Naming (10%; all ps < .0002). No significant differences were found for TMT-B (p > .05).
Conclusions
Present findings revealed that while the NP-NUMBRS and NEUROPSI norms yielded similar NCI rates, and LAN-M norms underestimated NCI on three tests. This highlights the importance of carefully considering available normative adjustments for Spanish-speakers when applying them to specific populations.

Abstract
The success of interferon-free regimens using new direct-acting antiviral (DAA) is a revolution and major breakthrough in the development of new therapeutic options against hepatitis C virus (HCV). Accumulating evidence suggest sustained virological response (SVR) with DAA in 95% of patients. To date, however, there are very few data related to efficacy of DAA in the Pakistani population. We aimed to investigate the efficacy of sofosbuvir-based regimen among Pakistani population. A total of 1,913 patients who attained SVR24 after being treated with sofosbuvir and ribavirin from August 2015 to March 2017 were enrolled in this study. We analyzed the demographic, clinical and virological data and screened all patients for HCV in March 2017 to evaluate the response rate. We found an overall response rate of 92.8%. In addition, we also observed lower response rates among older patients. It can be inferred that a large proportion of patients achieved SVR after treatment with sofosbuvir-based regimen.

Abstract
The objective of the study was to reveal the factors associated with variable interval to ovulation following a single dose of prostaglandin F2α (PGF2) in Beetal goats. In experiment 1, the extent of ovulation time was demonstrated after synchronizing Beetal goats (n=38) by using a single injection of PGF2 based on corpus luteum detection by B-mode transrectal ultrasonography. Ovulations were detected every 6h from PGF2 until ovulation. To explore the changes in follicular dynamics, endocrine profiles and behavioural events due to the variation in the interval to ovulation, another set of goats (n=13; experiment 2) were synchronized by a single dose of PGF2 given at random days of the luteal phase. Follicular dynamics were monitored every 12h from PGF2 until ovulation and oestrus was detected by apronized bucks every 6h from PGF2 treatment. Blood sampling (3mL) for oestradiol-17β and progesterone was done every 12h from PGF2 until ovulation and every 2h for LH assay by radioimmunoassay. Data were analysed by Student’s t-test, general linear models, and Pearson coefficient correlation (SPSS, version 20.0, SPSS Inc., Chicago, IL, USA). Results revealed that ovulation time varied from 60 to 96h after PGF2, and 57% of ovulations occurred by 72h after PGF2 (experiment 1). Based on this observation, goats (n=13) in second experiment were retrospectively divided into early and late ovulators (i.e. 72 and 84h following PGF2, respectively). Onset of oestrus, peak oestradiol-17β concentration, and LH surge after PGF2 were first observed in early than late ovulators (P<0.05). The goats having greater follicle diameter and smaller corpus luteum diameter at the time of PGF2 ovulated earlier than late ovulators (5.4±0.2v. 4.3±0.2mm and 10±0.6v. 11.8±0.3mm, respectively; P<0.05). Likewise, plasma progesterone concentration tended to be lower (P=0.087) in early than late ovulators. However, interval from onset of oestrus to peak LH and ovulation, duration of standing oestrus, interval from LH peak to ovulation, diameter and growth rate of preovulatory follicles, and number of ovulations were similar (P>0.05) between early and late ovulators. In conclusion, the size of dominant follicle and corpus luteum at the time of PGF2 determines the interval to ovulation following a single dose of PGF2 during the luteal phase.

Abstract
The proton induced nuclear reactions on 55Mn were considered to investigate for the production of 52Fe. The experimental results obtained by 55Mn(p,4n)52Fe reaction were compared with the results of nuclear model calculations using the codes ALICE-IPPE, EMPIRE 3.2 and TALYS 1.9. The thick target yields (TTY) of 52Fe were calculated from the recommended excitation functions. Analysis of impurities was also discussed. A comparison of the various radio-impurities showed that for the production of 52Fe via 55Mn(p,4n)52Fe reaction, energy ranges from 70→45 MeV could be the method of choice, which gives high yield with minimum impurities to make it as a potential candidate for theranostic applications and in particular, Positron Emission Tomography (PET).

Abstract
BACKGROUND AND PURPOSE Polymorphisms in coagulation genes have been associated with early-onset ischemic stroke. Here we pursue an a priori hypothesis that genetic variation in the endothelial-based receptors of the thrombomodulin-protein C system (THBD and PROCR) may similarly be associated with early-onset ischemic stroke. We explored this hypothesis utilizing a multi-stage design of discovery and replication. METHODS Discovery was performed in the Genetics-of-Early-Onset Stroke (GEOS) Study, a biracial population-based case-control study of ischemic stroke among men and women aged 15-49 including 829 cases of first ischemic stroke (42.2% African-American) and 850 age-comparable stroke-free controls (38.1% African-American). Twenty-four single-nucleotide-polymorphisms (SNPs) in THBD and 22 SNPs in PROCR were evaluated. Following LD pruning (r2≥0.8), we advanced uncorrelated SNPs forward for association analyses. Associated SNPs were evaluated for replication in an early-onset ischemic stroke population (onset-age<60 years) consisting of 3676 cases and 21118 non-stroke controls from 6 case-control studies. Lastly, we determined if the replicated SNPs also associated with older-onset ischemic stroke in the METASTROKE data-base. RESULTS Among GEOS Caucasians, PROCR rs9574, which was in strong LD with 8 other SNPs, and one additional independent SNP rs2069951, were significantly associated with ischemic stroke (rs9574, OR = 1.33, p = 0.003; rs2069951, OR = 1.80, p = 0.006) using an additive-model adjusting for age, gender and population-structure. Adjusting for risk factors did not change the associations; however, associations were strengthened among those without risk factors. PROCR rs9574 also associated with early-onset ischemic stroke in the replication sample (OR = 1.08, p = 0.015), but not older-onset stroke. There were no PROCR associations in African-Americans, nor were there any THBD associations in either ethnicity. CONCLUSION PROCR polymorphisms are associated with early-onset ischemic stroke in Caucasians.

Abstract
Steatocystoma is a benign adnexal tumor arising from the pilosebaceous duct junction. It can be classified into two groups (steatocystoma simplex and steatocystoma multiplex). Steatocystoma simplex, which presents as a solitary, non-herited very rare lesion in adult. It occurs most commonly in the axillae, in the sternal region and on the arms. Scalp is an extremely rare location. We report a case of 49-years-old male admitted in Department of Surgery, Dhaka Medical College & Hospital, Dhaka, Bangladesh on February 2017 presented with slowly progressing painless, soft, yellowish, single smooth surface mass on the left parietal scalp which had persisted for a period of 8 years. The histopathologic examination revealed a thin-walled cyst consisting of stratified squamous epithelium with lack of granular layer and containing sebaceous gland close to the wall. These findings were consistent with steatocystoma. At the 4-month follow-up, there was no sign of recurrence or development of the steatocystoma or any other masses.

Abstract
BACKGROUND Skeletal metastases often occur in men with castration-resistant prostate cancer (CRPC) where bone biomarkers are prognostic for overall survival (OS). In those with highly elevated markers, there is preferential benefit from bone-targeted therapy. In the phase IIIS0421 docetaxel +/- atrasentan trial, clinical covariates and bone biomarkers were analyzed to identify CRPC subsets with differential outcomes. SUBJECTS AND METHODS Markers of bone resorption [N-telopeptide-NTx; pyridinoline-PYD] and formation [C-terminal collagen propeptide-CICP; bone alkaline phosphatase-BAP] were measured in pre-treatment sera. Bone biomarkers and clinical covariates were included in a Cox model for OS; bone markers were added in a stepwise selection process. Receiver operating characteristic (ROC) curves were constructed for risk factor models +/- bone markers. Significant variables were allowed to compete in a classification and regression tree (CART) analysis. Hazard ratios(HR) were calculated by comparing OS in each of the terminal nodes to a reference group in a Cox model. RESULTS 750 patients were included. Each bone marker significantly contributed to the risk factor-adjusted OS Cox model, with higher levels associated with worse OS. BAP (HR = 1.15, p = 0.008), CICP (HR = 1.27, p < 0.001), and PYD (HR = 1.21, p = 0.047) in combination were significantly associated with OS. Prognostic accuracy was improved by addition of bone markers to clinical covariates. CART analysis selected CICP, BAP, hemoglobin, and pain score for the final OS model, identifying five prognostic groups. CONCLUSIONS Elevated serum bone biomarker levels are associated with worse OS in bone-metastatic CRPC. Bone biomarkers can identify unique prognostic subgroups. These results further define the role of bone biomarkers in the design of CRPC trials.

Abstract
Introduction Proximal cervical internal carotid artery stenosis greater than 50% merits revascularization to mitigate the risk of stroke recurrence among large-vessel anterior circulation strokes undergoing mechanical thrombectomy. Carotid artery stenting necessitates the use of antiplatelets, and there is a theoretical increased risk of hemorrhagic transformation given that such patients may already have received intravenous thrombolytics and have a significant infarct burden. We investigate the outcomes of large-vessel anterior circulation stroke patients treated with intravenous thrombolytics receiving same-day carotid stenting or selective angioplasty compared to no carotid intervention. Materials and methods The study cohort was obtained from the National (Nationwide) Inpatient Sample database between 2006 and 2014, using International Statistical Classification of Diseases, ninth revision discharge diagnosis and procedure codes. A total of 11,825 patients with large-vessel anterior circulation stroke treated with intravenous thrombolytic and mechanical thrombectomy on the same day were identified. The study population was subdivided into three subgroups: no carotid intervention, same-day carotid angioplasty without carotid stenting, and same-day carotid stenting. Outcomes were assessed with respect to mortality, significant disability at discharge, hemorrhagic transformation, and requirement of percutaneous endoscopic gastronomy tube placement, prolonged mechanical ventilation, or craniotomy. Results This study found no statistically significant difference in patient outcomes in those treated with concurrent carotid stenting compared to no carotid intervention in terms of morbidity or mortality. Conclusions If indicated, it is reasonable to consider concurrent carotid stenting and/or angioplasty for large-vessel anterior circulation stroke patients treated with mechanical thrombectomy who also receive intravenous thrombolytics.
