Abstract
West Bengal, a significant landmass of eastern India with its varied topography, edaphic, and climatic conditions facilitates diversified forest types and conducive microhabitats for a wide array of macro-fungal wealth and the members of Aphyllophorales in particular. Detailed macro-microscopic characterizations and chemical reactions were performed to systematically identify the specimens using standard key and literatures. Six members of Aphyllophorales collected from different parts of West Bengal, India and four species belonging to the family Polyporaceae [Hexagonia tenuis (Fr.) Fr., Polyporus arcularius (Batsch) Fr., P. tricholoma Mont. and Lenzites elegans (Spreng.) Pat.] were identified, and a single species was identified under Meripiliaceae [Physisporinus lineatus (Pers.) F. Wu, Jia J. Chen & Y.C. Dai] and Meruliaceae [Bjerkandera fumosa (Pers.) P. Karst.]. The detailed description along with field and herbarium photographs, macro-morphology, and microscopic features of six species are provided in this article.

Abstract
Introduction: Human Immunodeficiency Virus (HIV) causes severe public health problems. Despite the use of Highly Active Antiretroviral Therapy (HAART), opportunistic infections remain a serious problem in HIV infection. HIV seropositive women are at a higher risk of acquiring Vulvovaginal Infections (VVI), compared to their HIV seronegative counterparts. Also, the large untreated asymptomatic populations remain a source for transmitting agent. Aim: To identify the occurrence of vaginitis in symptomatic and asymptomatic HIV seropositive women. Materials and Methods: HIV seropositive female patients (60 symptomatic and 60 asymptomatic for vulvovaginitis) in the reproductive age group of 18-60 years were screened for their vaginal flora in a tertiary care hospital in East Delhi, India. Wet mount, Gram stain, and culture were performed to screen the samples for vaginitis. Asymptomatic samples were processed to check for asymptomatic VVI. Nugent and Amsel’s score were calculated for Bacterial Vaginitis (BV), and Donders classification was used for Aerobic Vaginitis (AV). Sabouraud’s Dextrose Agar (SDA) was used for fungal cultures, and Fluconazole and Voriconazole sensitivity was tested. The descriptive analysis of compiled data with Chi-square tests where applicable to compare differences between proportions was done. Results: As per the Nugent's score, 90% of symptomatic and 86.66% asymptomatic HIV reactive females had BV. Nugent scoring was found to be a better diagnostic criterion for BV. AV was observed in 33.33% asymptomatic patients. Candida albicans (C.albicans)was the most common agent isolated from 68.75% of Vulvovaginal Candidiasis (VVC) cases. Dual infection of BV and Candidiasis was reported to be 18.33% in symptomatic and 15% in asymptomatic HIV seropositive females. Conclusion: In the present study, despite Antiretroviral Therapy (ART), attendees manifested significantly with BV infection in both groups. VVC due to C. albicans was also predominant in both groups. Co-infection with BV and VVC was the highlight of this study as dual infections of BV and AV remain under-diagnosed as per Sexually Transmitted Infection (STI) syndromic management protocols. The clinicians need to identify AV as a separate entity as treatment modalities are essentially different.

Abstract
Production of quality jute fibre primarily depends on the retting process of jute. However, the quality of retting water is of great concern because of the scarcity of available water bodies for retting. A study conducted on physico-chemical and microbiological changes in retting water (pre- and post-retting) from four intensively jute-growing districts namely Nadia, North 24 Parganas, Hooghly and South Dinajpur of West Bengal, India, during jute retting. The post-retting water samples recorded lower pH (6.22 to 7.08) and higher EC (electrical conductivity) (0.509 to 0.850 ds/m) compared with pre-retting water samples (pH 6.63 to 7.44; EC 0.197 to 0.330 ds/m) collected from all the four districts under study. The biological oxygen demand (BOD) and chemical oxygen demand (COD) increased several folds in the post-retting water samples indicating very high microbial growth and activities and depleted oxygen level compared with pre-retting water. The Ca + Mg (calcium + magnesium) content in pre-retting water was high (24.15 to 36.60 ppm) which raised further (61.30 to 103.67 ppm) in post-retting water, while the bicarbonate content also increased and ranged between 2.72 and 6.81 me/l in post-retting water compared with its status in pre-retting water (1.30 to 3.15 me/l). The post-retting water was found to be a rich source of nutrients like nitrogen (N), phosphorus (P), iron (Fe), manganese (Mn), zinc (Zn) and copper (Cu) which increased substantially because of jute retting as compared with their status in pre-retting water. The population of pectinolytic, xylanolytic, cellulolytic and ligninolytic bacterial cfu (colony forming unit) increased by 1.5 times in post-retting water as compared with pre-retting water, because these specific bacterial population were involved in the degradation of pectin, xylan, cellulose and lignin during retting of jute. Thus, post-retting water can be judiciously used as a potent source of primary, secondary and micronutrients for succeeding crops besides having higher BOD and COD as a result of higher microbial growth related to jute retting.

Abstract
This study aimed at investigating the protective role of CoQ10 against cadmium (Cd)-induced reproductive toxicity in male rats. Adult male Wistar rats were exposed to an acute dose of Cd (25 mg/kg bwt; Cd group), Cd+CoQ10 (25 mg/kg bwt Cd+10 mg CoQ10; Cd-Q10 group) and distilled water (control) in vivo for 15 consecutive days and semen quality was assessed. A significant reduction was noted in sperm concentration, progressive motility, morphology and DNA integrity in both Cd- and Cd-Q10 groups in comparison to control indicating Cd-induced testicular lipid per oxidation (LPO) and decline in indigenous antioxidant defense system as measured by total antioxidant capacity (TAC) (p<0.05). However, simultaneous co-administration of CoQ10 along with Cd (Cd-Q10 group) was able to improve sperm concentration, motility, progressive motility, morphology, DNA integrity, and testicular TAC as well as lower LPO compared to Cd group (p<0.05). Results indicate that used dose of CoQ10 is capable of moderately ameliorating reproductive toxicity of Cd by improving semen quality and reducing testicular oxidative stress.

Abstract
BACKGROUND With the emergence of carbapenem-resistant isolates, the therapeutic alternatives have become limited. Various factors are responsible for carbapenem-resistant Enterobacteriaceae (CRE) gut colonization. This study was conducted to determine predictors for CRE gut colonization in neonates who were hospital delivered and admitted in a neonatal intensive care unit (NICU). METHODS Three rectal swabs were collected from 300 hospital-delivered and NICU-admitted neonates (likely to stay for >3 days). The data collected for the possible risk factors for CRE gut colonization were namely mode of delivery, prolonged rupture of membrane >18 hours, period of gestation, birth weight, meconium-stained liquor, ventilation, intravenous catheter, nasogastric (NG) tube, NG feeding, breastfeeding, katori spoon feeding, top feeding, expressed breastmilk, antibiotics administration, and duration of hospitalization. P < .05 was considered as statistically significant. RESULTS A total of 26 cases of CRE were isolated from 300 neonates. Statistically significant risk factors were found to be NG tube, breastfeeding, NG feeding, top feeding, expressed breastmilk, ventilation, antibiotic administration, and duration of hospitalization. Top feeding and antibiotics administration were identified as 2 independent risk factors by multiple logistic regression. CONCLUSIONS Active surveillance of cultures from hospitalized patients and implementation of preventive efforts can reduce the risk of CRE.

Abstract
OBJECTIVE Intellectual disability in a child places great stress on a family and caregiver and this leads to significant socio-occupational dysfunction and impaired quality of life for caregivers. This study aimed to assess socio-demographic characteristics, burden, and psychiatric morbidity of the caregivers of persons with intellectual disability, as well as to determine the variables that correlated with burden and psychiatric morbidity. METHODS An observational study was carried out in an outpatient psychiatric unit of a tertiary care teaching hospital in India from October 2014 to April 2015. A total of 100 caregivers of intellectually impaired individuals were assessed for burden and psychiatric morbidity. RESULTS In all, 39% of the caregivers had a high burden score, 46% perceived mild-to-moderate burden severity, and 15% perceived no to mild burden. Mild-to-moderate depressive symptoms were present in 23% and 16% had severe-to-extremely severe depressive symptoms. Mild-to-moderate anxiety symptoms were evident in 19% of caregivers and a further 19% had severe-to-extremely severe anxiety symptoms. CONCLUSION Routine assessment of burden and psychiatric morbidity in the caregiver will help to reduce their burden and thus help them care for their children more appropriately and efficiently.

Abstract
Background: An outfall of urbanization in developing countries has been the mushrooming of slums where dwellers live in pitiable environmental conditions representing the lowest rung of social strata. This group is more vulnerable to practicing deleterious social habits, including tobacco and alcohol abuse. Aim: The present study was undertaken to understand the strength of association between risk factors suspected of causing oral precancer among slum dwellers in Delhi. Subjects and Methods: A house-to-house survey was conducted in an urban slum cluster situated in the heart of Delhi city by a single trained investigator who recorded oral mucosal lesions according to WHO criteria. Demographic details and history of suspected risk factors was recorded by personal interview of each subject. The obtained data was coded, cleaned, and analyzed manually. Chi-square test was applied and Odds’ ratios were calculated to analyze the association of risk factors with oral precancer. A statistically significant difference was set at 95% confidence interval. Results: A total of 479 subjects of both sexes were examined and 31 cases clinically diagnosed as having oral precancer, of which majority were leukoplakia. All cases except one reported practicing habits that are known risk factors for oral precancer, i.e., smoking/smokeless tobacco, chewing betel leaf/nut, and combination of these habits with alcohol. Association of oral precancer with smokeless tobacco was higher than that with smoking or chewing betel leaf/nut alone. Conclusion: Practicing combination of habits with alcohol was found to be the most strongly associated risk factor for oral precancer.
