Abstract
This study was planned to determine arsenic (As) (10 mg/kg body weight given through oral gavage) induced behavioral and cholinergic perturbations in three different age groups of rats; young (postnatal day 21), adult (3 months), and aged (18 months) at 7 days post-acute exposure ( n = 6 for each of the four groups of all three age points). Further, we also evaluated the ameliorative effect of essential metal zinc (Zn; 0.02% through drinking water) and an antioxidant, α-tocopherol (vitamin E; 125 mg/kg body weight through oral gavage) against As-induced neurotoxicity. As exposure showed significant alterations in behavioral functions (open-field behavior, total locomotor activity, grip strength, exploratory behavior, and water maze learning). Cholinergic studies in three brain regions (cerebral cortex, cerebellum, and hippocampus) of different age groups also showed significant increase in acetylcholine levels and a decrease in acetylcholinesterase activity. These effects were more pronounced in hippocampus followed by cerebral cortex and cerebellum. Among the three different age points, aged animals were found to be more vulnerable to the As-induced toxicity as compared to young and adult animals suggesting that As neurotoxicity is age dependent. These As-induced alterations were significantly reversed following supplementation with Zn or vitamin E. However, vitamin E was found to elicit greater protection as compared to Zn in restoring the altered behavioral and cholinergic perturbations, providing evidence for As-induced oxidative damage.

Abstract
BACKGROUND Limited information is available about the risk factors associated with death among patients of influenza A (H1N1) in India. AIMS To describe the epidemiology of laboratory-confirmed influenza A (H1N1) patients and identify risk factors associated with death. SETTINGS AND DESIGN We reviewed the surveillance data of laboratory-confirmed patients in Tamil Nadu, India, for the year 2010. We conducted a case-control study by comparing 70 laboratory-confirmed A (H1N1) patients who died (cases) with 210 A (H1N1) patients who recovered (controls) to identify the risk factors for deaths. MATERIALS AND METHODS We interviewed the controls and immediate care-takers of the influenza patients who died to collect information about socio-demographic details and co-morbid conditions. We used an abstraction form to collect the information about the clinical details from the case records of the hospitals where the cases and controls received treatment. STATISTICAL ANALYSIS We analysed the surveillance data by time, place and person. We conducted univariate and multivariate logistic regression analysis for identifying factors associated death. RESULTS During 2010, 1302 laboratory-confirmed cases were reported to the Tamil Nadu surveillance unit. Of these, 72 patients died (case fatality=5.5%). About 2/3 of the cases and 40% of the deaths were from three districts. On multivariate analysis, past history of diabetes, treatment in private hospitals, treatment with corticosteroids during illness, visit to >1 healthcare facility before laboratory confirmation and delay of >48 h in starting antivirals were found to be independently associated with the deaths. CONCLUSIONS Influenza patients with previous history of diabetes, who had treatment with corticosteroids during illness, and started with antivirals after 48 h of onset of symptoms, were at higher risk of adverse outcome. In order to reduce the risk of death during future waves of influenza in Tamil Nadu, the physicians need to be sensitised regarding (1) higher risk of adverse outcomes among A (H1N1) patients with diabetes; (2) adherence to the national protocol for categorisation of cases; (3) prompt initiation of antivirals for severe cases; and (4) avoidance of systemic corticosteroids during management.

Abstract
Regeneration of pulp-dentin complex in an infected necrotic tooth with an open apex is possible if the canal is effectively disinfected. The purpose of this case report is to add a regenerative endodontic case to the existing literature about using Platelet Rich Fibrin (PRF). A nine year old boy who accidently broke his immature maxillary central incisor tooth, developed pulpal necrosis with apical periodontitis. After the access cavity preparation, the canal was effectively irrigated with 20 ml of 5.25% sodium hypochlorite solution and 10ml of 0.2% chlorhexidine solution and dried with paper points. Triple antibiotic paste was placed inside the canal and left for 21 days. 12 ml of whole blood was drawn from the patient's right antecubital vein and centrifuged for 10 minutes to obtain the Choukroun's PRF. After the removal of the triple antibiotic paste, the PRF was placed into the canal till the level of cementoenamel junction and 3mm of grey MTA was placed directly over the PRF clot. The setting of MTA was confirmed 3 days later and the tooth was double sealed with GIC and Composite restoration. After 1 year the clinical examination revealed negative responses to percussion and palpation tests. The tooth responded positively to cold and electric pulp tests. Radiographic examination revealed continued thickening of the dentinal walls, root lengthening, regression of the periapical lesion and apical closure. On the basis of the results obtained in our case report we conclude that revitalization of necrotic infected immature tooth is possible under conditions of total canal disinfection and PRF is an ideal biomaterial for pulp-dentin complex regeneration.

Abstract
We evaluated the protective effects of gallic acid (3,4,5-trihydroxybenzoic acid) on hepatic lipid peroxidation products, antioxidants, glycoprotein components, and lipids in streptozotocin-induced type II diabetic rats. To induce type II diabetes, rats were injected with streptozotocin intraperitoneally at a single dose of 40 mg/kg. Gallic acid (10 and 20 mg/kg) treatment was given to diabetic rats orally using an intragastric tube daily for 21 days. Streptozotocin-induced diabetic rats showed a significant increase in the levels of blood glucose, hepatic lipid peroxidation products, glycoprotein components, lipids, and the activity of HMG-CoA reductase and a significant decrease in the levels of plasma insulin and liver glycogen. In addition to this, the activities/levels of hepatic antioxidants were decreased in diabetic rats. Gallic acid (10 and 20 mg/kg) treatment showed significant protective effects on all the biochemical parameters studied in diabetic rats. Thus, our study shows the antihyperglycemic, antilipid peroxidative, antioxidant, and antilipidemic effects of gallic acid in streptozotocin-induced type II diabetic rats. A diet containing gallic acid may be beneficial to type II diabetic patients.

Abstract
We show that mechanical stiffness is a useful metric for characterizing complex collagen assemblies, providing insight about aggregation products and pathways in collagen-based materials. This study focuses on mechanically robust collagenous membranes produced by an electrochemical synthesis process. Changing the duration of the applied electric field, or adjusting the electrolyte composition (by adding Ca(2+), K(+), or Na(+) or by changing pH), produces membranes with a range of Young's moduli as determined from force-displacement measurements with an atomic force microscope. The structural organization, characterized by UV-visible spectroscopy, Raman spectroscopy, optical microscopy, and atomic force microscopy, correlates with the mechanical stiffness. These data provide insights into the relative importance of different aggregation pathways enabled by our multiparameter electrochemically induced collagen assembly process.

Abstract
BACKGROUND The role of intrapleural fibrinolytic agents in the treatment of childhood empyema has not been established. A randomised double blind placebo controlled trial of intrapleural urokinase was performed in children with parapneumonic empyema. METHODS Sixty children (median age 3.3 years) were recruited from 10 centres and randomised to receive either intrapleural urokinase 40 000 units in 40 ml or saline 12 hourly for 3 days. The primary outcome measure was length of hospital stay after entry to the trial. RESULTS Treatment with urokinase resulted in a significantly shorter hospital stay (7.4 v 9.5 days; ratio of geometric means 1.28, CI 1.16 to 1.41 p=0.027). A post hoc analysis showed that the use of small percutaneous drains was also associated with shorter hospital stay. Children treated with a combination of urokinase and a small drain had the shortest stay (6.0 days, CI 4.6 to 7.8). CONCLUSION Intrapleural urokinase is effective in treating empyema in children and significantly shortens hospital stay.

Abstract
Drowning and near drowning is a common cause of accidental death all over the world; specially in road traffic accidents over bridges, swimming pool and boat tragedies. Cold water drowning resulting in hypothermia can lead to instant death before actual drowning. Five cases of near drowning (ND) in cold water, who presented with varied clinical picture like coma with decerebrate rigidity and fixed dilated pupils, hypertension with coma and delayed pulmonary oedema (Secondary drowning) are reported. Energetic management with continuous positive airway pressure was very rewarding in all patients with ND except in one who had transient organic psychosis persisting for two weeks followed by minimal cognitive defect in the form of slow mentation, lack of drive and mild irritability (Bender Gestald Test Score of 53). We have tried to analyse some of the clinical features of ND and the sequel associated with it. The management as well as recent developments in the field are also discussed.

Abstract
The photooxidation of pyrimidine bases viz., uracil and cytosine in presence of peroxydiphosphate (PDP) in aqueous solution at natural pH (approximately 7.5) has been carried out in a quantum yield reactor using a high-pressure mercury lamp. The rates of oxidation and quantum yields of pyrimidine oxidation have been found to increase with increase in [PDP] while they are independent of [pyrimidine] and light intensity. On the basis of these experimental results, product analysis and existence of isosbestic points a probable mechanism is suggested in which peroxydiphosphate ion on photolysis gives phosphate radical anions which initiates the reaction by adding to C(5) or C(6) of pyrimidine base leading to the formation of pyrimidine radical via radical cation or hydrolysis. This further reacts with PDP and gives the final products 5,6-dihydroxy pyrimidine and isobarbituric acid.

Abstract
The phytochemical study using Caralluma umbellata (Asclepiadaceae) whole plant allowed the isolation of a novel pregnane glycoside named carumbelloside-I (3-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl-3beta,14beta -dihydroxypregn-5-en-20-one). Carumbelloside-I was evaluated for both antinociceptive activity and anti-inflammatory activity. The antinociceptive activity was evaluated in mice using the writhing test method, while the anti-inflammatory activity was evaluated in rats using the paw edema test with carrageenin. Carumbelloside-I has significant antinociceptive action. It has no anti-inflammatory activity.

Abstract
Very few studies report the analysis of sister chromatid exchanges in ovarian cancer patients. We tested the null hypothesis that SCE frequency increases with the advancing stages of ovarian cancer and follows a Poisson distribution. As controls we examined age- and sex-matched healthy volunteers who had no such past history. An increased average SCE frequency was observed in ovarian cancer patients (6.34 +/- 0.09) vis-à-vis controls (4.47 +/- 0.12). Further, the data also suggested a stage-wise increase in the SCE frequency.

Abstract
A comparative study of perinatal mortality patterns over a period was conducted at a teaching hospital of South India. Among the 6,048 babies born from January 1984 to December 1985 (Group A), there were 265 (43.8/1000) still births and 127 (22.0/1000) early neonatal deaths. Three hundred and thirty seven (41/1000) babies were still born and 235 (29.8/1000) early neonatal deaths out of 8,215 deliveries during 1992-93 (Group B). The perinatal mortality rate (PMR) in Groups A and B were 57.9/1000 and 57.7/1000 respectively. Unbooked cases accounted for the majority (> 75%) of perinatal deaths during both the periods. The overall mortality rates in unbooked cases were three to four times higher than booked cases. Among the various causes of still births, antepartum haemorrhage and uterine rupture had increased. Septicaemia was the major cause of early neonatal deaths in Group A, but in Group B birth asphyxia and prematurity were the leading causes. Effective interventions like creating awareness among the target population to utilise maternal and child health services and early referral of high risk cases with improved intranatal and perinatal care can decrease the perinatal mortality.

Abstract
Silver staining of nucleolar organizing regions (NOR) is common, but a standard protocol is lacking. A modification of a rapid silver nitrate staining technique for NORs is presented here. Advantages of the modified technique include reliability, speed, cost and the fact that it can be carried out in the light.

Abstract
Resonance assignments of nonexchangeable base and sugar protons of the self-complementary dodecanucleotide d-GGATCCGGATCC have been obtained by two-dimensional NMR methods and strategies derived from interproton distance calculations on different secondary structures of nucleic acids. Conformational details about the glycosidic dihedral angle and sugar pucker have been derived from the relative intensities of cross peaks in the two-dimensional J-correlated and nuclear Overhauser enhancement correlated spectra in D2O solution. It is observed that d-GGATCCGGATCC assumes a predominantly B-type conformation with sequence-dependent changes along the chain. The recognition site of BamHI shows a distinctly different geometrical environment. The sugar rings of G1 and G7 assume a C3'-endo geometry while the rest of the sugars possess C2'-endo geometry.

Abstract
Cardiac transplantation, along with successful immunosuppressive therapy, is emerging as a reasonable therapeutic procedure for prolonging the life of patients with end-stage coronary artery disease. Nutritional management is an important factor in total patient care. Dietary principles as outlined here are intended to serve as nutrition guidelines rather than dietary restrictions. The primary goal is to promote sound nutritional health without aggravating the metabolic consequences of immunosuppressive therapy.
