Abstract
Health informatics is one of the main branch of engineering which provides a solution to a variety of problems like delayed, missed or incorrect diagnoses with the help of computational techniques. With the help of technologies such as bio-computing, health informatics, the disaster
impacts on both human health and biological factors can be reduced to a large extend. Using these computational technologies, the country’s economy can also get boosted up and due to increased disease-causing pathogens, which directly impact the human health system. In this research
work, a different type of sugarcane disease is detected and classified because manual identification is difficult and time-consuming. So, the farmers couldn’t find a better solution, than on the whole, they go for stubble burning, which is an alarming issue both on human and environmental
wellness. The burning of bagasse causes bagassois, an interstitial lung disease that affects the tissues present in the lung through the air sacs. So, this sugarcane disease detection needs to be done early to avoid various health and environmental issues. The proposed work consists of the
detection of four types of sugarcane leaf disease directly from the field. The sequence of methods is capturing images with WSN nodes, pre-processing with image enhancement and noise removal (IENR), segmentation with Fuzzy membership function and clustering (FMFC), feature extraction using
Gray Level Co-occurrence Matrix Vector (GLCMV) and classification using Support Vector Machine (SVM). With the help of the effective proposed method, the highest parameters like precision, accuracy, sensitivity, and specificity for sugarcane leaf disease have been obtained. Based on the successful
implementation process, the accuracy stated for the four sugarcane diseases along with the execution time is given below as Smut disease (87.12, 1.01 sec), Rust disease (90.23, 1.02 sec), Grassy Shoot disease (95.34, 1.047 sec), Red Rot disease (95.51, 1.04 sec).

Abstract
Background and Aim: Cyclophosphamide therapy is known to be associated with the risk of female infertility as a result of ovarian toxicity. Alpha-lipoic acid (LA) and omega-3 fatty acids are known for their antioxidant and anti-inflammatory activities. The present study investigated the potential protective effect of alpha-LA, omega-3 fatty acids, and its combination against cyclophosphamide-induced ovarian toxicity in rats. Materials and Methods: Thirty rats were equally divided into Groups I, II, III, IV, and V. Group I was normal control, wherein the rats were fed with normal feed and water ad libitum. Group II served as cyclophosphamide-induced group, wherein the rats were injected with cyclophosphamide at 75 mg/kg through intraperitoneal route once a week to induce ovarian toxicity. Groups III and IV were treated with alpha-LA at the rate of 25 mg/kg and omega-3 fatty acids at the rate of 400 mg/kg, respectively, in parallel to cyclophosphamide induction as in Group II. Group V animals were coadministered with alpha-LA (25 mg/kg) and omega-3 fatty acids (400 mg/kg) along with cyclophosphamide induction as in Group II. The respective treatments were administered daily through oral route for a period of 30 days. Regularity of estrous cycle was evaluated by vaginal cytology. Post-treatment period, the animals were humanely sacrificed, and the blood samples were subjected to the estimation of follicle-stimulating hormone (FSH) and estrogen. The ovarian tissue was weighed and subjected to histopathology, transmission electron microscopy, estimation of decreased glutathione (GSH), and tumor necrosis factor (TNF)-alpha. Results: Rats treated with cyclophosphamide alone manifested irregularity in estrous cycle, increased FSH, and reduced estrogen levels. The ovaries showed decreased GSH and increased TNF-alpha concentrations. Histopathological and transmission electron microscopic analysis of the ovarian follicles revealed degenerative changes. Administration of alpha-LA and omega-3 fatty acids as well as the combination of both the treatments demonstrated significant normalization of the estrous cycle and antioxidant defense mechanism as well as ameliorated the hormonal profile and histological architecture of the ovarian follicles. However, appreciable synergistic efficacy of the combination therapy (alpha-LA+omega-3 fatty acids) with respect to the monotherapies was not observed in the present study. Conclusion: The efficacy of alpha-LA and omega-3 fatty acids against cyclophosphamide-induced ovarian toxicity could be attributed to its antioxidant and anti-inflammatory activities that prevented the oxidative damage to the ovaries caused by cyclophosphamide. Hence, our findings suggest that dietary supplementation of alpha-LA and omega-3 fatty acids in women receiving cyclophosphamide therapy could carry potential benefits in preventing cyclophosphamide-induced infertility in childbearing women.

Abstract
The purpose of the study was to determine the changes in knowledge of information technology (IT) professionals after receiving a nutrition education intervention for a month. The sample comprised of 40 IT professionals (29 males and 11 females). The sample was drawn from four IT companies of Hyderabad city using random sampling techniques. The data on the general information of the subjects was collected. The data regarding the commonly accessed sources of nutrition and health information by the subjects was also obtained from the study. The intervention study group received nutrition education by distribution of the developed CD-ROMs to them followed by interactive sessions. To assess the impact of nutrition education intervention, the knowledge assessment questionnaire (KAQ) was developed and administered before and after the education programme. A significant improvement in the mean nutritional knowledge scores was observed among the total study subjects from 22.30 to 40.55 after the intervention (p < 0.05). The findings support the importance of providing professionals with nutrition knowledge to promote healthy dietary behaviors.Thus, the method of e-learning and development of CD-Rom is essential for teaching the educated groups on nutrition, physical activity and overall health education to improve their health, lifestyle and eating habits.

Abstract
The present study was aimed to investigate whether α-tocopherol could protect the chromium (Cr) VI-induced oxidative stress in female reproductive system of rats and to explore the underlying mechanisms of the same. A total of 24 Wistar adult female rats were equally divided into four groups. Group 1 served as control, while groups 2 and 3 were administered K2Cr2O7 (10 mg/kg b.wt. s.c. single dose). In addition to Cr, group 3 also received α-tocopherol @ 125 mg/kg daily by oral gavage for 14 days. Group 4 was maintained as α-tocopherol control (dose as above). Body weights were recorded at the beginning and at the end of experiment. Further, the rats were observed for occurrence of estrus cycle. At the end of 14 days, blood samples were drawn for sero-biochemical analysis. Subsequently, all the rats were sacrificed to collect uterus along with ovaries for assay of tissue peroxidation, anti-oxidant and functional markers, and histopathology. Administration of chromium (Cr) VI to rats revealed a significant (P < 0.05) accumulation of cholesterol and a prolonged diestrus phase leading to impaired fertility in rats. Administration of chromium (Cr) VI significantly (P < 0.05) reduced the antioxidant markers such as superoxide dismutase (SOD) and reduced glutathione (GSH), along with significant (P < 0.05) increase in peroxidation markers such as malondialdehyde and protein carbonyls in ovaries. The functional marker in serum such as total protein was decreased, whereas other functional markers viz alanine transaminase (ALT), blood urea nitrogen (BUN) and creatinine were increased. Prominent pathological changes were observed in the uterus and ovaries of Cr-treated group. Co-treatment with α-tocopherol significantly (P < 0.05) reversed the (Cr) VI induced changes.

Abstract
Our earlier studies indicated the role of neurotransmitter systems in lead (Pb) induced behavioral perturbations. In this study, we examined the alterations in synaptosomal acetylcholine (ACh), epinephrine, dopamine, acetylcholinesterase (AChE), and mitochondrial monoamine oxidase (MAO) in the cerebellum and hippocampus of perinatally Pb-exposed rats. Rats (Wistar) were exposed to 0.2% Pb (Pb acetate in drinking water of mother) from gestational day 6 and the pups were exposed lactationally (through mother's milk) to Pb till weaning (postnatal day 21). Studies conducted on different postnatal days (PND 21, 28, 35 and 60) showed significant decreases in synaptosomal AChE and mitochondrial MAO activities, and increases in the levels of ACh, dopamine and epinephrine in the cerebellum and hippocampus of Pb-exposed rats. These alterations were greater at PND 35 and more pronounced in the cholinergic system (ACh and AChE) of hippocampus and the aminergic system (epinephrine, dopamine and MAO) of cerebellum. The total locomotor activity and exploratory behavior were also decreased significantly in Pb-exposed animals corresponding to the alterations observed in cholinergic and aminergic systems. Calcium administration together with Pb, however significantly reversed the Pb-induced alterations in transmitters and enzymes, as well as exploratory and motor behavior suggesting protective effect of calcium in Pb-exposed animals.

Abstract
An experimental study was conducted to evaluate the toxicological effects, if any, due to feeding of Bt (Bacillus thuringiensis) cotton plants to sheep. A total of 32 sheep of one year of age belonging to Deccani breed were randomly divided into four groups, consisting of eight sheep in each group. Group 1 was maintained on basal diet (concentrate feed at the rate of 300 g + green fodder at the rate of 3 kg/sheep/day), group 2 on non-Bt cotton plant at the rate of 1.5 kg + green fodder at the rate of 1.5 kg + concentrate feed at the rate of 300 g/sheep/day, group 3 on Bt cotton plants (50%) at the rate of 1.5 kg + green fodder at the rate of 1.5 + concentrate feed at the rate of 300 g/sheep/day, and group 4 on Bt cotton plants ad libitum + concentrate feed at the rate of 300 g/sheep/day. All the groups of sheep were maintained for three months and various hemato-biochemical parameters were studied at monthly intervals. The activity of aspartate transaminase, gamma glutamyltransferase, and creatine kinase in sera samples, and the concentration of blood urea nitrogen and creatinine did not differ significantly among different groups at different time intervals. The histological examination of liver and kidney did not reveal any significant changes in Bt and non-Bt cotton-fed groups. In conclusion, the results of the present investigation enunciated that feeding of genetically modified (Bt) cotton plants to sheep was without detrimental effects in the biological system of sheep.

Abstract
Estuaries, the important component of natural environment are under pressure nowadays due to pollution from different sources like industries, agricultural fields etc. Ennore estuary one of the highly polluted estuary situated in Chennai, Tamilnadu, India, due to heavy industrialization surrounding this site poses serious threat to its inhabitants. The present paper focuses on studying the response of the fish Mugil cephalus with reference to its antioxidants during their exposure to metals like iron and chromium present in the industrial effluents that are discharged into the Ennore estuary. The results on comparison with unpolluted Kovalam estuary showed that fish from Ennore experiences severe oxidative stress with significant alteration being observed with antioxidant enzyme activities. Since these results were also found to vary with seasons, the determination of oxidative stress biomarkers in M. cephalus along with seasonal variations may serve as a convenient approach during pollution biomonitoring programme.

Abstract
Exposure to heavy metals and organic pollutants in natural water bodies can have detrimental effects on fish health. A combination of biochemical and energy studies were used to observe the changes in fish liver mitochondria in response to environmental pollutant induced nitrative stress in natural field conditions. The fish samples Mugil cephalus were collected from polluted (Ennore) and unpolluted (Kovalam) estuaries for a period of two years. The results revealed elevated nitrite (NO2-) and nitrate (NO3-) levels, increased nitric oxide (NO) synthesis and 3-nitrotyrosine expression, decreased respiratory chain enzyme activities and ATP/ADP ratio, reduced mitochondrial superoxide dismutase (MnSOD), glutathione peroxidase (Gpx) levels, diminished thiol status that leads to alterations in the mitochondrial function and elevated mitochondrial heat shock protein 70 (mtHSP70) expression (30%) to a significant extent in fish from the polluted estuary than in the unpolluted estuary. The overexpression of HSP70 under stress may aid mitochondrial survival by protecting against nitrative stress induced damage. The results also reveal the percentage increase in fish liver mitochondrial HSP70 in response to cumulative effect of environmental pollutants.

Abstract
Under a multicentre study conducted by the Indian Council of Medical Research, 2205 samples of dairy milk were collected from rural and urban areas of 12 states representing different geographical regions of India. These samples were analysed for residues of DDT and different isomers of HCH by gas-liquid chromatography. Analytical quality assurance between various participating laboratories was ensured through analysis of check samples. The residues of DDT and HCH were detected in more than 80% of samples analysed. Concentrations of DDT residues, alpha-HCH, beta-HCH, gamma-HCH and delta-HCH exceeded their maximum residue limits prescribed by the Ministry of Health and Family Welfare of the Indian Government in 37, 21, 42, 28 and 4% of the samples, respectively. Median values of DDT and HCH found in dairy milk in India were more than the corresponding values reported from most other countries. The results showed significant variations in the incidence as well as level of these contaminants in dairy milk from different regions of the country.

Abstract
Homoeotic appendages provide a system for the analysis of neural path-finding in which the appendage is mismatched with its segmented ganglion. Central projections of sensory neurons from homoeotic antennapedia regenerates induced by antennal amputation in the stick insect, Carausius morosus, are described. The majority of afferent axons project to the olfactory lobe as in the normal antennal nerve, but they do not give rise to compact glomeruli. Nor does the form of the projection resemble that of leg sensory nerves in thoracic ganglia. The projection of antennapedia regenerate neurons in Carausius resembles the antennapedia mutant of Drosophila except that some primary afferents bypass the olfactory lobe and take several courses through the brain, sometimes reaching distant contralateral areas. It appears that these wandering fibers, having bypassed the olfactory lobe, tend to follow established tracts and to arborize or to deviate at circumscribed synaptic areas. The behavioral evidence for sensory input from antennapedia regenerates is equivocal.

A total of 280 families represented by 1435 members were covered. A 3-dietary survey was conducted by a weighed method for estimating the food intake. Nutritional value of the food consumed was calculated. Nutritional status was assessed by anthropometry. Results were analysed by five age groups-preschool age, school age, adolescents, adults and people above 50 yr. The intake of green leafy vegetables, milk, animal protein foods and oils was very low in all age groups. The adequacy of energy ranged from 60 to 91 per cent, protein from 73 to 91 per cent, niacin from 52 to 84 per cent. The intake of vitamin A and ascorbic acid was grossly inadequate in every group. The nutritional status of school children and adolescents was less than the values reported for higher income group in the same region.
