Abstract
OBJECTIVE To validate a Rapid Neurodevelopmental Assessment (RNDA) tool for use by child health professionals to determine neurodevelopmental impairments (NDIs) in young adolescents aged 10-16 years in Bangladesh. STUDY DESIGN In a convenience sample of community children (n = 47), inter-rater reliability was determined between four testers, and concurrent validity was determined by simultaneous administration of an intelligence quotient (IQ) test (Wechsler Intelligence Scale for Children, Revised) by a child psychologist. RESULTS Inter-rater reliability was excellent between the testers on the 47 children administered the RNDA (kappa = 1.00). Significantly lower IQ scores were obtained in those identified with 'any (>1) NDI' (n = 34) compared with those with no NDI (n = 13) on Verbal IQ (P-value < 0.0001), Performance IQ (P-value < 0.0001) and Full-scale IQ (P-value < 0.0001) scores on the Wechsler Intelligence Scale for Children, Revised. CONCLUSION The RNDA shows promise as a tool for use by child health professionals for identifying NDIs in young adolescents aged 10-16 years. A larger study sample is needed to determine its usefulness for identification of some impairments not found in the study population, i.e. gross motor, fine motor, hearing and seizures.

Abstract
Aflatoxin B1 is a carcinogen produced by Aspergillus flavus and a few related fungi that are often present in many food substances. It interacts synergistically with Hepatitis B or C virus (HBV, HBC) infection, thereby increasing the risk of hepatocellular carcinoma (HCC). The G to T transversion at the third position of codon 249 (AGG) of the TP53 gene, substituting arginine to serine, is the most common aflatoxin-induced mutation linked to HCC. This study examined mutations in TP53 by PCR-RFLP analysis and by measurement of an aflatoxin-albumin adduct as a biomarker for human exposure of aflatoxin B1 by indirect-competitive ELISA, in samples collected from healthy controls as well as patients with hepatitis in Hyderabad, Andhra Pradesh, India. A total of 238 blood samples were analyzed the presence of the G to T mutation. Eighteen of these samples were from HBV-positive subjects, 112 of these were from subjects who had HBV-induced liver cirrhosis, and 108 samples were taken from subjects without HBV infection or liver cirrhosis (control group). The G to T mutation was detected in 10 samples, 8 of which were from subjects positive to both HBV and aflatoxin-albumin adduct in blood (p=0.07); whilst two were from individuals who were HBV-negative, but positive for the aflatoxin-albumin adduct (p=0.14). The aflatoxin-albumin adduct was detected in 37 of 238 samples, 29 samples were from HBV-positive subjects and eight were from individuals who were positive for both HBV and the TP53 mutation (p=0.07). The concentration of aflatoxin-albumin adduct ranged from 2.5 to 667pg/mg albumin. Despite low incidence of the G to T mutation, its detection in subjects positive to aflatoxin-adducts is indicative of a strong association between the mutation and aflatoxin exposure in India.

Abstract
The conversion of tamarind seed into bio-oil by pyrolysis has been taken into consideration in the present work. The major components of the system were fixed bed fire-tube heating reactor, liquid condenser and collector. The crushed tamarind seed in particle form was pyrolyzed in an electrically heated fixed bed reactor. The products were liquid, char and gasses. The parameters varied were reactor temperature, running time, gas flow rate and feed particle size. The maximum liquid yield was 45 wt% at 400°C for a feed size of 3200 μm diameter at a gas flow rate of 6l/min with a running time of 30 min. The obtained pyrolysis liquid at these optimum process conditions were analyzed for physical and chemical properties to be used as an alternative fuel. The results show the potential of tamarind seed as an important source of alternative fuel and chemicals as well.

Abstract
BACKGROUND Home-based screening to identify young children at risk for neurodevelopmental impairments (NDIs) is needed to guide the targeting of child neurodevelopmental intervention services in Bangladesh. This study aimed to validate such a tool for children under age 2 years. METHODS A Developmental Screening Questionnaire was administered to mothers of children aged 0-<2 years in an urban community. Inter-rater reliability among the interviewers, who were high school graduates, was determined. All children who were screen positive and a proportion of screen negatives were subsequently assessed for NDIs by professionals. Sensitivity and specificity were calculated by comparing screening with assessment results. RESULTS Mean kappa coefficient of agreement among interviewers was 0.95. A total of 197 children were screened, of whom 17% screened positive. Fifty-one children, including 24 screen negatives, were assessed for NDIs. Screen-positivity was significantly different between income groups (P = 0.019), and higher in stunted children (odds ratio = 5.76, 95% confidence interval = 1.72-19.28), indicating good discriminant validity Specificity was excellent (84-100%) for all developmental domains. Sensitivity was 100% for vision and hearing; 70% for speech; and 63%, 53%, 48%, and 45% for gross motor, behaviour, fine motor and cognitive impairments, respectively. CONCLUSION A tool for screening <2-year-old children at risk for NDIs showed high specificity; and was able to identify all children at risk for vision and hearing impairments, nearly three-fourths with speech impairments, two-thirds with gross motor impairments, and about half with behavioural, cognitive and fine motor impairments. The Developmental Screening Questionnaire tool has potential for use by frontline workers to screen large populations and to link to definitive assessment as well as intervention services.

Abstract
The LD50 of DDVP (Dichloro, dimethyl vinyl phosphate) for Rattus norvegicus was 21.4 mg/kg. b.w. The two sub lethal doses 1 and 3 mg/kg showed many histopathological changes in the working heart muscles and also showed significant necrosis in this S-A node, A-V node and bunble of His of the cardiac conducting system. These sublethal doses of the OP pesticide caused a significant inhibition of AChE. The maximum inhibition was noticed at the highest dose. The enhanced inhibitory constant Km and ACh contents in the heart muscles with the increase of dose showed inhibition of enzyme. The constant Vmax showed competitive nature of inhibition. A significant inhibition of AChE (69%) indicated that DDVP is a strong inhibitor of enzyme in heart.
