Abstract
Breast cancer stands as the prevailing invasive cancer globally, bearing high mortality rates among women. Existing evidence indicates diminished survival rates in younger patients. Consequently, this study endeavors to assess and contrast the pathological features of breast cancer in women under 40 years of age with their older counterparts. Conducted as a cross-sectional analysis, this study encompasses 560 patients diagnosed with breast cancer, seeking treatment at Mymensingh Medical College Hospital (MMCH), Community Based Medical College Bangladesh (CBMCB) and several private hospitals in Mymensingh. The gathered data incorporates information such as age, residential area, occupation, tumor histopathology, TNM classification, staging and status of hormone receptor. The patients' mean age (standard deviation) was 49.7±11.9 years, with 20.5% below 40, most were from rural areas and were housewives. Ductal carcinoma prevailed as the most common histopathologic type (87.67%). However, younger patients exhibited a higher prevalence of lobular and other rare carcinomas compared to their older counterparts (p=0.04). Additionally, the younger group demonstrated larger tumor sizes (p=0.01), lymphatic node involvement (p=0.04) and advanced staging (p=0.004). Notably, younger age showed more negativity for estrogen and/or progesterone receptors. The results suggested that women under 40 years old exhibit more aggressive tumor characteristics and a more severe form of breast cancer compared to their older counterparts.

Abstract
BACKGROUND Systemic candidiasis is an important nosocomial infection in neonatal intensive care units. The objective of this study was to identify the change in the profile of neonatal candidiasis in a tertiary neonatal intensive care unit (NICU) in eastern India in recent times. METHODS It was a retrospective review of case records from 2014 to 2019 from a tertiary NICU of eastern India. Data of the fungal sepsis, demographic details, risk factors of fungal sepsis and mortality were collected from 103 neonates. RESULTS One hundred and three neonates had blood culture positive for fungal species of which 91 (88.3%) infants weighed ≥1500 g and 66 (64%) infants were term. There was significant higher incidence of candidiasis among outborn (Relative risk of outborn 18.84, 95% CI 10.74-33.05). Prolonged antibiotic usage (>14 days), meropenem usage (>5 days), central catheterization (>5 days), invasive mechanical ventilation (>5 days), surgical intervention were found in 64 (62.1%), 46 (44.6%), 31(30.0%), 40 (38.8%) and 39 (37.8%) infants. Non albicans candida (NAC) was isolated as the predominant species (82/103, 79.6%). Resistance to both of fluconazole and amphotericin B were found in 19 (18.4%) babies. Presence of NAC infection and resistance to both amphotericin B and fluconazole were independent predictors of candida associated mortality in NICU. CONCLUSION Neonatal candidiasis is found among outborn infants with higher birth weight and gestational age. NAC species are predominant organisms with resistance to common antifungal drugs.

Abstract
Increase platelet count can accompany various cancers including lung cancer. This finding has recently been suggested to indicate poor prognosis. In patients with malignancies, thrombocytosis has previously been related disease stage, histological type and survival. In this study, the prevalence of thrombocytosis and the prognostic information provided by platelet count were analyzed in patients with stage IV Non-Small Cell Lung Cancer (NSCLC) with an aim to assess elevated platelet count as a prognostic factor in patients with stage IV NSCLC and to investigate whether there is relationship between thrombocytosis, other clinico-pathologic factors and median survival. This prospective observational study was conducted in National Institute of Cancer Research and Hospital (NICRH), Dhaka, Bangladesh from September 2019 to August 2020. A total of 108 patients were enrolled purposively. Detail history taking, thorough physical examination was done along with relevant investigations. Data were collected by semi structured questionnaire and analysis was done with the help of Statistical Package for Social Science (SPSS), version 21.0. The mean age of the patients was found 56.4±12.2 years with range from 35 to 75 years. Majority (79.6%) patients were male, 52.8% patients came from low income and 36.1% were farmer. Majority (40.7%) were symptomatic; in bed >50.0% of day. Almost two third (59.3%) had <5.0% weight loss. Almost three fourth (69.4%) had squamous cell carcinoma. At the time of first assessment 75(69.4%) patients had normal and 33(30.6%) had elevated platelet count level. Age, sex and histological type were statistically not significant between normal and elevated platelet count level groups. But performance status, weight loss were statistically significant (p<0.05) between two groups. According to univariate analysis, age, performance status at presentation, weight loss more than 10.0% for 3 months and platelet count prior the start of treatment were all significant predictors for the overall survival. In multivariate analysis age, performance status at presentation and initial thrombocytosis were independent prognostic determinants for overall survival. Median survival time was significantly higher for the normal platelet count group and elevated platelet count group (7.5 months versus 5.5 months) respectively (95% CI, 5.5-7.5), p<0.001. The frequency of thrombocytosis in patients with stage-IV NSCLC at first presentation was 30.6% and median survival time in these patients was significantly shorter compared in patients without thrombocytosis. These results concluded that an elevated platelet count could be a useful prognostic factor for survival in patients with stage-IV NSCLC.

Abstract
The pro-inflammatory IFNγ-STAT1 pathway and anti-inflammatory IL10-STAT3 pathway elicit cellular responses primarily utilizing their canonical STATs. However IL10 mediated STAT1 and IFNγ mediated STAT3 activation is also observed, suggesting crosstalk of these functionally opposing signaling pathways can potentially reshape the canonical dynamics both STATs and alter the expression of their target genes. Herein, we measured the dynamics of STATs in response to different doses of IL10 or IFNγ and in their co-stimulation and employed quantitative modeling to understand the regulatory mechanisms controlling signal responses in individual and co-simulation scenarios. Our experiments show, STAT3 in particular, exhibits a bell-shaped dose-response while treated with IFNγ or IL10 and our model quantiatively captured the dose-dependent dynamics of both the STATs in both pathways. The model next predicted and subsequent experiments validated that STAT3 dynamics would robustly remain IL10 specific when subjected to a co-stimulation of both IFNγ and IL10. Genes common to both pathways also exhibited IL10 specific expression during the co-stimulation. The findings thus uncover anovel feature of the IL10-STAT3 signaling axis during pathway crosstalk. Finally, parameter sampling coupled to information theory based analysis showed that bell-shaped signal-response of STAT3 in both pathways is primarily dependent on receptor concentration whereas robustness of IL10-STAT3 signaling axis in co-stimulation results from the negative regulation of the IFNγ pathway.

Abstract
Worldwide, 50% of soil is acidic, which induces aluminium (Al) toxicity in plants, as the phyto-availability of Al3+ increases in acidic soil. Plants responds to Al3+ toxicity by exuding organic acids into the rhizosphere. The organic acid responsible for Al3+ stress response varies from species to species, which in the case of blackgram (Vigna mungo L.) is citrate. In blackgram, an Arabidopsis malate transporter, AtALMT1, was overexpressed with the motive of inducing enhanced exudation of malate. Transgenics were generated using cotyledon node explants through Agrobacterium tumefaciens-mediated transformation. The putative transgenics were initially screened by AtALMT1-specific genomic DNA PCR, followed by quantitative PCR. Two independent transgenic events were identified and functionally characterized in the T3 generation. The transgenic lines, Line 1 and 2, showed better root growth, relative water content and chlorophyll content under Al3+ stress. Both lines also accounted for less oxidative damage, due to reduced accumulation of ROS molecules. Photosynthetic efficiency, as measured in terms of Fv /Fm , NPQ and Y(II), increased when compared to the wild type (WT). Relative expression of genes (VmSTOP1, VmALS3, VmMATE) responsible for Al3+ stress response in blackgram showed that overexpression of a malate transporter did not have any effect on their expression. Malate exudation increased whereas citrate exudation did not show any divergence from the WT. A pot stress assay found that the transgenics showed better adaptation to acidic soil. This report demonstrates that the overexpression of a malate transporter in a non-malate exuding species improves adaptation to Al3+ toxicity in acidic soil without effecting its stress response mechanism.

Abstract
Solid tumors elicit suppressive T cell responses which impair antigen-presenting cell (APC) functions. Such immune suppression results in uncontrolled tumor growth and mortality. Addressing APC dysfunction, dendritic cell (DC)-mediated anti-tumor vaccination was extensively investigated in both mice and humans. These studies never achieved full resistance to tumor relapse. Herein, we describe a repetitive RM-1 murine tumor rechallenge model for recurrence in humans. Using this newly developed model, we show that priming with tumor antigen-pulsed, Toll-like receptor (TLR)2 ligand-activated DCs elicits a host-protective anti-tumor immune response in C57BL/6 mice. Upon stimulation with the TLR2 ligand peptidoglycan (PGN), the tumor antigen-pulsed DCs induce complete resistance to repetitive tumor challenges. Intra-tumoral injection of PGN reduces tumor growth. The tumor resistance is accompanied by increased expression of interleukin (IL)-27, T-box transcription factor TBX21 (T-bet), IL-12, tumor necrosis factor (TNF)-α and interferon (IFN)-γ, along with heightened cytotoxic T lymphocyte (CTL) functions. Mice primed four times with PGN-stimulated tumor antigen-pulsed DCs remain entirely resistant to repeat challenges with RM-1 tumor cells, suggesting complete prevention of relapse and recurrence of tumor. Adoptive transfer of T cells from these mice, which were fully protected from RM-1 rechallenge, confers anti-tumor immunity to syngeneic naive recipient mice upon RM-1 challenge. These observations indicate that PGN-activated DCs induce robust host-protective anti-tumor T cells that completely resist tumor growth and recurrence.

Abstract
Global incidence of dengue has drastically increased in the last few years. Despite the global morbidity and mortality associated with dengue infection, mechanisms of immune control and viral pathogenesis are poorly explored. Pancytopenias, along with increased oxidative stress, are salient clinical findings in severe dengue patients. Previously, we demonstrated significant differences of circulating immune complexes (CICs) among severe and non-severe dengue patients. Accordingly, here we sought to determine the contributory role of affinity-purified antibody-bound CICs in dengue severity. To characterize intracellular oxidative stress induced by antibody-bound CICs, 5-(and-6)-chloromethyl-2'-7'-dichlorodihydrofluorescein diacetate (DCFDA) was measured by flow cytometry. At the same time, CICs sensitized healthy red blood cells (RBC) and patients' RBC morphology was determined by scanning electron microscopy and flow cytometry analysis. Erythrophagocytosis and ferritin levels were further determined in severe and non-severe dengue patients. Our results showed that the severe patients had high titres of immunoglobulin (Ig)M-bound CICs (P < 0·0001) in their sera, increased intracellular oxidative stress (P < 0·0001), high ferritin levels (P < 0·0001), altered morphology of RBC and finally enhanced erythrophagocytosis. This study shows for the first time that RBC morphology is altered in severe dengue patients. Taken together, this study suggests that the enhanced IgM-bound CICs could contribute to the increased oxidative stress and act directly on RBC destruction of severe dengue patients, and is an important pathophysiological determinant. Hence, IgM-bound CICs can serve as an important laboratory parameter to monitor dengue infection progression.

Abstract
Commercial high-resolution optical microscopes are essential for microscopy imaging; however, they are expensive and bulky, which limits their use in point-of-care devices, resource-limited areas, and real-time imaging of a sample in a large apparatus. In this study, we report a novel compact (10 cm × 5 cm × 5 cm, without the light source) lightweight (∼0.5 kg) submicron-resolution inverted optical microscope at low cost (∼$ 300). Our technique utilises the proximity of the image sensor to a commercial microscope objective lens for compactness of the microscope. The use of an image sensor with a small pixel size helps to reduce the information loss, which provides high-resolution images. Moreover, our technique offers a freedom to tailor the design of microscope according to the required resolution, cost, and portability for specific applications, which makes it a suitable candidate for affordable point-of-care devices. Images of several micron-to-submicron scale patterns and spherical beads are acquired to observe the resolution and quality of the images obtained using our microscope. In addition, we demonstrate the applications of our microscope in various fields such as recording of high-speed water microdroplet formation inside a microfluidic device, high-resolution live cell imaging inside an incubator, and real-time imaging of crack propagation in a sample under stretching by a material testing system (MTS). Therefore, this portable and inexpensive microscope provides the essential functionalities of a bulky expensive high-performance microscope at a lower cost. LAY DESCRIPTION: Microscope is an essential tool in research allowing for observation of microsized objects and life forms. Contemporary commercial high-resolution microscopes have long optical paths involving series of lenses and filters. Although this configuration precisely corrects for optical distortions and produces clear images, it makes modern microscopes very costly and bulky, restricting their usage to low-funded research laboratories and at remote places. We have developed a simple digital microscope with high-resolution but with much smaller size and lighter in weight at low cost by removing the long optical terrain. Our microscope consists of a commercial microscope objective lens for magnification and semiconductor image sensor with small pixels placed right after the lens, both of which are affordable and easily available. The small pixel size helps to translate the magnified analogue sample image to high-resolution digital image. In our paper, we show that our microscope can view micro and submicron-sized patterns and beads. Moreover, our fist-sized microscope can be placed inside an incubator for real-time imaging of cells or rotated sideways for recording submicron-sized crack generation due stretching of novel materials, both of which could not be accomplished with the 2 feet tall laboratory microscopes.

Abstract
Incidence of coronary artery disease (CAD) is increasing in developing countries in Bangladesh with improvement of socioeconomic status, urbanization, changes of dietary habits and lifestyle. Dyslipidaemia is one of the major contributors increase CAD risk. This study was aimed to find out the association of low level HDL-C with acute coronary syndrome. This cross sectional study was conducted in the department of cardiology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from August 2009 to May 2010. Sociodemographic characteristics, smoking, hypertension, FBS, serum total cholesterol level, HDL-C, LDL-C, Triglyceride level were important variable considered. A total number of 100 respondents consisted of 50 cases (patient) Group I and 50 healthy people (control) Group II. Investigations included ECG, Troponin-I, FBS and Fasting Lipid Profile. The data was analyzed by computer with the help of SPSS. Chi-square test, T-test, ANOVA test used as test of significance. The mean level in cases of HDL-C 39.3±5.1 and in control level HDL-C 34.2±3.4 statistically significant (p<0.0001). In both group low concentration HDL-C (<40mg/dl) risk for CAD. Un-adjusted odds ratio 95% CI determinants of ACS, HDL-C of OR was 0.2. So, HDL-C is not protective factor. In multivariate logistic regression analysis that adjusted for confounders of HDL-C level (age, sex, smoking, hypertension, TC, LDL-C, TG) associated with ACS. HDL-C was strong predictor of ACS (RR in the highest) compared with lowest quarantile = 0.02; (95% CI=0.003-0.173; P for trend <0.0001). The study reflected that low HDL-C level associated with ACS. Categorization of patients with ACS on the basis HDL-C level may be helpful for risk stratification and management.

Abstract
Cardiovascular diseases (CVD) is the leading cause of death worldwide, responsible for one third of death, coronary artery disease (CAD) is the most common cause. Dyslipidaemiais one of the major contributors increased of CAD risk. This study was aimed to find out the relationship between triglyceride and HDL cholesterol ratio with acute coronary syndrome. This cross sectional study was conducted in the department of Cardiology, Mymensingh Medical College Hospital from August 2009 to May 2010. Smoking, hypertension, serum total cholesterol level, serum HDL-C, LDL-C, triglyceride (TG) level were important variable considered. A total number of 100 respondents consisted of 50 cases (patient) and 50 healthy persons (control). Investigations included ECG, Troponin-I, FBS and lipid profile. The data was analyzed by computer with the help of SPSS; Chi-square test, 't' test, ANOVA test used as test of significance. The mean level in cases of TG 168.2±88.0 vs. HDL 41.3±5.1 in control level TG 141.2±45.3 and HDL 34.2±3.4. TG/HDL ratio cases 4.2±1.7 and control 4.1±1.3. This ratio >4 is atherogenic for CAD. Unadjusted odds ratio TG/HDL ratio level high (>1). In multivariable regression analysis, TG/HDL ratio was strong relation with ACS. The study reflected that high TG/HDL ratio is associated with ACS. Categorization of patient with ACS on the basis of high TG/HDL ratio will be helpful for risk stratification and management.

Abstract
Coronary heart disease (CHD) is the most common cause of heart disease and is the single most important cause of premature death in developed world. Recognizing a patient with ACS is important because the diagnosis triggers both triage and management. cTnI is 100% tissue-specific for the myocardium and it has been shown to be a very sensitive and specific marker for acute myocardial infarction (AMI). Ventricular function is the best predictor of death after an acute coronary syndrome. It serves as a marker of myocardial damage, provides information on systolic function as well as diagnosis and prognosis. The study aimed at investigating the impact of elevated Troponin-I level on LV ejection fraction and in-hospital outcomes in patients with first attack of Non ST-segment Elevation Myocardial Infarction (NSTEMI). This prospective analytical study was conducted in the Department of Cardiology in Mymensingh Medical College Hospital from December 2015 to November 2016. Total 130 first attack of NSTEMI patients were included considering inclusion and exclusion criteria. The sample population was divided into two groups: Group I - Patients with first attack of NSTEMI with good LV function (LVEF: ≥55%). Group II - Patients with first attack of NSTEMI with LV systolic dysfunction (LVEF: <55%). Then Troponin-I and LVEF levels were correlated using Pearson's correlation coefficient test. In this study mean Troponin-I of Group I and Group II were 5.53±7.43 and 16.46±15.79ng/ml respectively. It was statistically significant (p<0.05). Echocardiography showed that patients with high Troponin-I level had low ejection fraction (LVEF) and patients with low Troponin-I level had preserved ejection fraction (LVEF). Analysis showed that patients with severe left ventricular systolic dysfunction (LVEF <35%) had the highest level of Troponin-I with worse in-hospital outcomes and vice versa-the patients with the preserved systolic function (LVEF ≥55%) had the lowest levels of Troponin-I with better in-hospital outcomes. In our study, it also showed that the levels of Troponin-I had negative correlation with LV ejection fraction levels, with medium strength of association (r= -0.5394, p=0.001). The study enabled us to conclude that, the higher was the Troponin-I level, the lower was the LV ejection fraction level and thus worse in-hospital outcomes in first attack of NSTEMI patients.

Abstract
Toll-like receptors (TLRs) are germline-encoded, non-clonal innate immune receptors, which are often the first receptors to recognize the molecular patterns on pathogens. Therefore, the immune response initiated by TLRs has far-reaching consequences on the outcome of an infection. As soon as the cell surface TLRs and other receptors recognize a pathogen, the pathogen is phagocytosed. Inclusion of TLRs in the phagosome results in quicker phagosomal maturation and stronger adaptive immune response, as TLRs influence co-stimulatory molecule expression and determinant selection by major histocompatibility complex (MHC) class II and MHC class I for cross-presentation. The signals delivered by the TCR-peptide-MHC complex and co-stimulatory molecules are indispensable for optimal T cell activation. In addition, the cytokines induced by TLRs can skew the differentiation of activated T cells to different effector T cell subsets. However, the potential of TLRs to influence adaptive immune response into different patterns is severely restricted by multiple factors: gross specificity for the molecular patterns, lack of receptor rearrangements, sharing of limited number of adaptors that assemble signalling complexes and redundancy in ligand recognition. These features of apparent redundancy and regulation in the functioning of TLRs characterize them as important and probable contributory factors in the resistance or susceptibility to an infection.

Abstract
Polyphenols can exert both, antioxidant and pro-oxidant properties, depending on cell types as well as their concentrations. Hence, it was of interest to examine if the naturally occurring resveratrol analog, trans-4,4'-dihydroxystilbene (DHS) also exert both these activities in a biphasic or cell-specific manner. In this study, we established the cytoprotective action of DHS against hydrogen peroxide (H2O2)-induced apoptotic death of the PC12 cells. DHS reduced mitochondrial membrane permeabilization and deactivated reactive oxygen species (ROS)-mediated caspase-3 activation in the H2O2-treated PC12 cells. However, it induced apoptosis in the human neuroblastoma SHSY-5Y cell line by destabilizing mitochondrial membrane, augmenting ROS and activating caspapse-3. DHS showed better activity than resveratrol in both the chosen models.

Abstract
An important driving force behind the sequence diversity of hepatitis B virus (HBV) is viral adaptation to host immune responses. To gain an insight into the impact of host immunity on genetic diversification and properties of HBV, we characterized HBV of genotype D from treatment-naive hepatitis B e antigen-positive (EP) and hepatitis B e antigen-negative (EN) patients with chronic hepatitis B (CHB), where HBV is under stronger immune pressure, with that of HBV derived from human immunodeficiency virus (HIV)/HBV-coinfected individuals, where HIV infection has significantly weakened the immune system. Full-length sequence analysis showed that HBV heterogeneity was most extensive in EN-CHB followed by EP-CHB and HIV/HBV coinfection. The relative magnitude of non-synonymous changes within B-cell epitopes was greater than that in T-cell epitopes of HBV open reading frames (ORFs) in both EP-CHB and EN-CHB. Nine amino acid substitutions were identified in B-cell epitopes and one in a T-cell epitope of HBV in EN-CHB, most of which resulted in altered hydrophobicities, as determined using the Kyte and Doolittle method, relative to wild-type residues found in HBV from the HIV-positive group. Additionally, 19 substitutions occurred at significantly higher frequencies in non-epitope regions of HBV ORF-P in EN-CHB than HIV/HBV-coinfected patients. In vitro replication assay demonstrated that the substitutions, particularly in reverse transcriptase and RNaseH domains of ORF-P, resulted in a decline in replication capacity of HBV. Hence, our results indicate that HBV adapts to increasing immune pressure through preferential mutations in B-cell epitopes and by replicative attenuation. The viral epitopes linked to immune response identified in this study bear important implications for future HBV vaccine studies.

Abstract
Toll-like receptors (TLRs) recognize pathogen-associated molecular patterns and results in innate immune system activation that results in elicitation of the adaptive immune response. One crucial modulator of the adaptive immune response is CD40. However, whether these molecules influence each other's expression and functions is not known. Therefore, we examined the effects of TLRs on CD40 expression on macrophages, the host cell for the protozoan parasite Leishmania major. While polyinosinic-polycytidylic acid [poly (I:C)], a TLR-3 ligand, lipopolysaccharide (LPS), a TLR-4 ligand, imiquimod, a TLR-7/8 ligand and cytosine-phosphate-guanosine (CpG), a TLR-9 ligand, were shown to enhance CD40 expression, CD40 stimulation enhanced only TLR-9 expression. Therefore, we tested the synergism between CD40 and CpG in anti-leishmanial immune response. In Leishmania-infected macrophages, CpG was found to reduce CD40-induced extracellular stress-regulated kinase (ERK)1/2 activation; with the exception of interleukin (IL)-10, these ligands had differential effects on CD40-induced IL-1α, IL-6 and IL-12 production. CpG significantly enhanced the anti-leishmanial function of CD40 with differential effects on IL-4, IL-10 and interferon (IFN)-γ production in susceptible BALB/c mice. Thus, we report the first systematic study on CD40-TLR cross-talk that regulated the experimental L. major infection.

Abstract
Triple-negative breast cancer (TNBC) is a distinct breast cancer subtype defined by the absence of estrogen receptor (ER), progesterone receptor (PR) and epidermal growth factor receptor 2 (HER2/neu), and the patients with TNBC are often diagnosed with higher rates of recurrence and metastasis. Because of the absence of ER, PR and HER2/neu expressions, TNBC patients are insensitive to HER2-directed and endocrine therapies available for breast cancer treatment. Here, we report that expression of atypical protein kinase C isoform, PKCλ/ι, significantly increased and activated in all invasive breast cancer (invasive ductal carcinoma or IDC) subtypes including the TNBC subtype. Because of the lack of targeted therapies for TNBC, we choose to study PKCλ/ι signaling as a potential therapeutic target for TNBC. Our observations indicated that PKCλ/ι signaling is highly active during breast cancer invasive progression, and metastatic breast cancers, the advanced stages of breast cancer disease that developed more frequently in TNBC patients, are also characterized with high levels of PKCλ/ι expression and activation. Functional analysis in experimental mouse models revealed that depletion of PKCλ/ι significantly reduces TNBC growth as well as lung metastatic colonization. Furthermore, we have identified a PKCλ/ι-regulated gene signature consisting of 110 genes, which are significantly associated with indolent to invasive progression of human breast cancer and poor prognosis. Mechanistically, cytokines such as TGFβ and IL1β could activate PKCλ/ι signaling in TNBC cells and depletion of PKCλ/ι impairs NF-κB p65 (RelA) nuclear localization. We observed that cytokine-PKCλ/ι-RelA signaling axis, at least in part, involved in modulating gene expression to regulate invasion of TNBC cells. Overall, our results indicate that induction and activation of PKCλ/ι promote TNBC growth, invasion and metastasis. Thus, targeting PKCλ/ι signaling could be a therapeutic option for breast cancer, including the TNBC subtype.

Abstract
Two different Toll-like receptors (TLRs) have been shown to play a role in host responses to Leishmania infection. TLR-2 is involved in parasite survival in macrophages upon activation by lipophosphoglycan (LPG), a virulence factor expressed by Leishmania. In contrast, activation of TLR-9 has been shown to promote a host-protective response. However, whether there is a relationship between the interaction of LPG and TLR-2, on one hand, with the effect of TLR-9, on the other hand, remains unknown. In this study, we report that in-vitro infection of macrophages with a L. major parasite with high expression levels of LPG results in decreased TLR-9 expression compared to infection with a L. major parasite with lower expression levels of LPG. Addition of anti-LPG as well as anti-TLR-2 antibodies prevents this reduction of TLR-9 expression. Also, the addition of purified LPG to macrophages results in a decrease of TLR-9 expression, which is shown to be mediated by transforming growth factor (TGF)-β and interleukin (IL)-10. Finally, in-vitro treatment of macrophages with anti-LPG and/or anti-TLR-2 antibodies before infection reduces the number of amastigotes in macrophages and co-treatment of mice with anti-TLR-2 antibodies and cytosine-phosphate-guanosine (CpG) reduces footpad swelling and parasite load in the draining lymph nodes, accompanied by an interferon (IFN)-γ-predominant T cell response. Thus, for the first time, we show how interactions between LPG and TLR-2 reduce anti-leishmanial responses via cytokine-mediated decrease of TLR-9 expression.

Abstract
Abstract
Hexavalent chromium is a widespread environmental contaminant and a known human carcinogen. Kinetics of reduction of hexavalent chromium by bio-molecule glycerol in micellar media have been studied spectrophotometrically. The cytoplasmic reduction of hexavalent chromium to trivalent chromium occurs in micro-heterogeneous systems. In vitro, the micelles are considered to mimic the cellular membranes. The electron transfer processes occurring in the micellar systems is considered as model to obtain insight into the electron transport process prevailing in biological systems. Micellar media is also a probe to establish the mechanistic paths of reduction of hexavalent chromium to trivalent chromium. Effects of electrolytes common to biological system are studied to establish the proposed reaction mechanism strongly.

Abstract
INTRODUCTION HIV/AIDS can lead to poverty affecting particularly women and young people and can halt or reverse socioeconomic development of a country. OBJECTIVE The objective of this study was to assess the socioeconomic consequences of HIV/AIDS within the family. MATERIALS AND METHODS A cross-sectional descriptive study was carried out among patients admitted in in-patient department and those attending integrated counseling and testing centre (ICTC) of School of Tropical Medicine, Kolkata. Data were gathered by interviewing the patients by using a predesigned questionnaire. RESULTS For prolonged duration and severity of disease, higher proportion of indoor patients reported loss of job, decreased family income, increased expenditure for care seeking, and faced greater economic consequences, reflected by selling assets. Loss of job was mainly due to illness (86.8%), disclosure of sero-status (13.2%), and predominantly among skilled workers. Assets were sold mainly to meet the cost of own illness for indoor patients, but more to meet the expenditure for husband's illness, in the case of ICTC patients. High school dropout seen in both groups was mainly due to economic reasons. HIV/AIDS status was known to other members of family for 84.8% of indoor patients out of which 15.4% experienced rejection by family members. Out of 72 ever married women indoor patients whose in-laws were aware of their HIV/AIDS status, 41.7%, 40.9%, and 33.33% reportedly were blamed for spouse's illness, and had strained relation with in-laws and spouse, respectively. CONCLUSION Intensive behavior change communication and provision of care and support are required to curb AIDS-related stigma, discrimination, and to maintain physical, mental, and social wellbeing of people living with HIV/AIDS.

Abstract
Dunnigan-type partial lipodystrophy (familial partial lipodystrophy, Dunnigan variety, FPLD2) can be caused by LMNA mutations. We identified a novel heterozygous LMNA mutation, P485R, in a patient referred to the International Registry of Werner Syndrome because of features consistent with that of progeroid disorder but who was wild type at the WRN locus. The novel mutation is located 2 amino acids away from the canonical FPLD mutations in exon 8 of the LMNA gene. Immunocytochemical analysis revealed abnormal nuclear morphology characteristic of laminopathies within primary fibroblast cultures, but not in a lymphoblastoid cell line, in keeping with previous observations. Our findings indicate that FPLD2 should be considered in the differential diagnosis of the Werner syndrome.
