Abstract
Vildagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor is effective in reducing HbA1c levels in patients with type 2 diabetes (T2DM) when administered as monotherapy, dual or triple combination therapy. In India, Vildagliptin is commonly prescribed in T2DM patients because it reduces mean amplitude of glycemic excursion (MAGE), has lower risk of hypoglycemia and is weight neutral. Early combination therapy with vildagliptin and metformin is effective and well-tolerated in patients with T2DM, regardless of age or ethnicity. In view of already existing data on vildagliptin and the latest emerging clinical evidence, a group of endocrinologists, diabetologists and cardiologists convened for an expert group meeting to discuss the role and various combinations of vildagliptin in T2DM management. This practical document aims to guide Physicians and Specialists regarding the different available strengths and formulations of vildagliptin for the initiation and intensification of T2DM therapy.

Abstract
Metabolic Syndrome (MetSyn) is a predictor of cardiovascular disease (CVD). About a third of urban Indians suffer from MetSyn. This study examined the prevalence of MetSyn among women living in urban slums. A cross-sectional survey was carried out between October 2017 and May 2018 among a non-probability sample of slum-dwelling women, 40-64 years of age, in six government-designated slums in Mysore, India. Data were collected on demographics, diet, behavioral risks, anthropometry, blood pressure, serum glucose, hemoglobin A1c, and serum lipids. The study used a definition of MetSyn from the International Diabetes Federation Task Force on Epidemiology and Prevention with an HbA1c measure for average blood glucose. About two-fifths of the 607 participants had MetSyn (41.5%; 95% CI: 37.7-45.5). Of those, 40.9% met three criteria, 38.1% four, and 25.0%, all five criteria. Elevated BP was the most prevalent MetSyn factor (79.6%), followed by increased waist circumference (54.5%), low HDL (50.1%), elevated Hb A1c (37.1%), and elevated triglycerides (36.1%). Odds for MetSyn were 1.52 times greater for those who were 50-59 years of age compared with those 40-49 years of age (adjusted odds ratio[AOR]:1.52; 95% CI:0.96-2.40). Women with mobility issues had 1.29 times higher odds of MetSyn than those without it (AOR: 0.76, 95% CI: 0.96, 1.75). Housewives had 1.29 times greater odds of MetSyn (AOR: 1.29, 95% CI: 1.00, 1.67). There is a high prevalence of MetSyn among urban slum-dwelling women in Mysore. There is a need for interventions aimed at reducing CVD risk factors in this population.

Abstract
BACKGROUND To examine the role of parity in coronary heart disease (CHD) among middle-aged Indian women living in government-designated slums in Mysore, India. METHODS Between October 2017 and May 2018, a cross-sectional study was carried out among women, 40-64 years of age, residing in government-designated slums in Mysore, India. In addition to socio-demographics, data were collected on CVD risk factors including use of tobacco and alcohol, diet, physical activity, sleep, quality of life, and personal and family history of chronic disease. Patients underwent a medical examination and a venous blood sample was taken for fasting lipid measurement. Resting electrocardiography was carried out by a trained medical technician. Multivariable logistic regression with associated 95% confidence intervals was used to examine the relationship between parity and coronary heart disease. RESULTS The prevalence of CHD in this sample of middle-aged women was 6.4%. Nulliparous women were at heightened risk for CHD compared to parous women with up to five live births. In the adjusted model, women who had 1-2 and 3-5 live births had 0.24 times lower odds (95% Confidence Interval [CI]: 0.05-1.29) and 0.38 times lower odds (95%CI: 0.178-0.87) of CHD, respectively, as compared to nulliparous women. CONCLUSION Among a fairly homogenous population of slum-dwelling women reporting almost universal breastfeeding for three or more months following birth, parity up to five births appeared protective against CHD. Further studies are needed to evaluate whether near universal breastfeeding rates in this population mediated the relationship of parity and CHD.

Abstract
Aims Metabolic Syndrome (MetS) is a strong predictor of Coronary Heart Disease (CHD). Studies in urban India have found about one-third of Indians suffer from MetS. Less is known about the prevalence of MetS in rural areas, where 70% of the population reside. This study examined the prevalence of Metabolic Syndrome in a population of rural women in India. Methods Data were gathered in a community-based study of 500 rural and tribal women residing in the Mysore district, between the age of 30–59 years. The study used the WHO STEPS approach, in which information on demographics and behavioral risk factors were collected. Along with anthropometric measurements, blood pressure, blood glucose, lipids were measured. A harmonized definition of MetS recommended by International Diabetes Federation Task Force on Epidemiology and Prevention was used in this study. Results Three out of five study participants were found to have MetS (47.1%, n = 223). Of those, 56.5% met 3 of the 5 criteria, 32.2% met 4 criteria, and 11.2% met all 5 criteria. Among the entire sample, low HDL was the most prevalent criterion (88.4%), followed by elevated glucose (57.9%), elevated triglycerides (49.3%), elevated BP (41.5%), and increased waist circumference (15.3%). In this sample, women with METS were generally older (p < 0.001), housewives (p = 0.001), that consumed salty highly processed foods (p = 0.020) and had low physical activity (p = 0.015). Conclusions This study showed a high prevalence of MetS in rural women. There is a compelling need for interventions aimed at reducing CHD risk factors in this population.

Abstract
Background: Globally, rates of obesity have trebled in the past four decades. India has more than 9.8 million men and 20 million women classified as obese. While poor diet and sedentary lifestyles are major causes, growing evidence suggests other factors like sleep-disordered-breathing may also be contributors. Methods: A cross-sectional survey was carried out between October 2017 and May 2018 among a nonprobability sample of slum-dwelling women, 40–64 years of age, in government-designated slums in Mysore, India. After the informed consent process, data were collected on sociodemographics, tobacco and alcohol consumption, diet, physical activity, sleep, quality of life, and personal and family history of diagnosed cardiometabolic disorders. Body mass index (BMI) was calculated using anthropometry. The serum was tested for HbA1c and lipid profile. Results: In this sample of slum-dwelling women, snoring was associated with obesity. Habitual snorers had more than double the odds (adjusted odds ratio [aOR] 2.05; 95% confidence interval [CI] 1.26–3.33; P < 0.004) of obesity I, and seven times the odds (aOR 7.71; CI: 3.58–16.62; P < 0.001) of being in the obesity II category compared to nonsnorers after adjustment for age, diabetes, hypertension, hypercholesterolemia, and daytime sleepiness. There was no difference in obesity status among participants reporting abnormal sleep duration, napping, daytime sleepiness, sleep apnea, insomnia, or the use of sleep medication. Conclusion: The relationship between snoring and obesity has not been well explored. This study among slum-dwelling Indian women found a significant relationship between snoring and obesity. Future research should explore the underlying mechanisms connecting snoring to BMI.

Abstract
A Gram-stain-positive coccus, strain JC304T, was isolated from a saltern of Nari along the Bhavnagar Coast, Gujarat, India. The 16S rRNA gene sequence analysis and sequence comparison data indicated that JC304T represented a member of the genus Salinicoccus and was most closely related to Salinicoccus roseus 9T (99.6 %), Salinicoccus luteus YIM 70202T (97.0 %), Salinicoccus hispanicus J-82T (97.0 %) and the remaining species of the genus Salinicoccus (<97 %). Genome relatedness based on DNA-DNA hybridization of JC304T with the type strains of the most closely related species was less than 46 % and the ΔTmwas >5 °C indicating that the strain represents a novel species of the genus Salinicoccus. Independent and concatenated phylogenetic analysis of recA/fusA gene translated product showed a clear distinction of JC304T from its phylogenetic neighbors. Diphosphotidylglycerol, phosphatidylglycerol, an unidentified glycolipid and three unidentified lipids (L1, L2 and L3) were the polar lipids of JC304T. Iso-C15 : 0 and anteiso-C15 : 0 were the major (>10 %) fatty acids in strain JC304T. The cell-wall amino acids were l-lysine and d-glycine. Hopanoids were not detected. The major isoprenoid quinone was menaquinone (MK-6). The DNA G+C content of JC304T was 48 mol%. On the basis of physiological, genotypic, phylogenetic and chemotaxonomic analyses, strain JC304T is considered to represent a novel species of the genus Salinicoccus, for which the name Salinicoccusamylolyticus sp. nov. is proposed. The type strain is JC304T (=KCTC 33661T=LMG 28757T).

Abstract
We present a 62-year-old lady admitted in our hospital with two episodes of acute ischemic stroke about 2 weeks apart. She was evaluated for acute ischemic stroke and was thrombolysed for recent stroke in right MCA territory first time. On further evaluation, she was found to have a RVOT mass. A transthoracic and transesophageal echocardiogram revealed a PFO and a large, 5.1 cm × 2.3 cm, ovoid, well circumscribed, echogenic mass in the right ventricle outflow tract attached by small pedicle to the ventricular side of anterior tricuspid leaflet, partly obstructing the right ventricular outflow tract and protruding through the pulmonic valve during systole. She was scheduled for surgery (right ventricular mass excision and PFO closure) after 3 weeks due to the risk of secondary hemorrhage in the infarcted area following thrombolysis and anticoagulation and so was discharged with medications after full neurologic recovery after about a week of hospital stay. She was readmitted 7 days after discharge, before the scheduled date of surgery with history of weakness of right upper limb, slurred speech and mild breathing difficulty lasting for about 20 min following which she improved slowly (transient ischemic attack). The tumor was completely removed with the stalk using cardiopulmonary bypass support. The histopathological findings confirmed the diagnosis of myxoma.

Abstract
BACKGROUND A pharmacoinvasive strategy may alleviate the logistical and geographical barriers in timely reperfusion of ST-segment elevation myocardial infarction (STEMI), especially in a developing country like India. AIM To assess the safety and efficacy of pharmacoinvasive strategy versus primary PCI in STEMI patients at 2 years. METHODS Patients enrolled in STEPP-AMI, an observational, multicenter, prospective study of 200 patients presenting with STEMI, were followed up for 2 years. Group 'A' comprised of patients with pharmacoinvasive strategy (n=45), and patients who underwent primary PCI (n=155) formed group 'B'. Primary endpoint was composite of death, cardiogenic shock, reinfarction, repeat revascularization of the culprit artery, or congestive heart failure at 30 days, with follow-up till 2 years. RESULTS The primary endpoint occurred in 11.1% and 17.8% in group A and in 3.9% and 13.6% in group B, at 30 days and 2 years, respectively (p=0.07, RR=2.87; 95% CI: 0.92-8.97 at 30 days and p=0.47, RR=1.31; 95% CI: 0.62-2.76). There was no difference in bleeding risk between groups, 2.2% in group A and 0.6% in group B ('p'=0.4). The infarct-related artery patency varied at angiogram; it was 82.2% in arm A and 22.6% in arm B ('p'<0.001). In group A, failed fibrinolysis occurred in 12.1%. CONCLUSION A pharmacoinvasive strategy resulted in outcomes that were comparable with primary PCI at 2 years, suggesting it might be a viable option in India. Larger studies are required to confirm these findings.

Abstract
OBJECTIVES This study was carried out to determine the incidence, clinical features, etiology and outcome of functional and intrinsic acute kidney injury (AKI) in preterm neonates. METHODS This is a prospective observational study on premature infants admitted to the neonatal intensive care unit (NICU) over an eight month period. All biochemical parameters of renal function tests were monitored and statically analyzed. RESULTS The study included 450 infants; of them 300 were inborn and 150 infants were outborn and transported to the NICU. Mean gestational age, weight, and age at the time of AKI diagnosis were 32.3 weeks, 1.66 kg and 3.23 days respectively. The male: female ratio was 1.84:1. Incidence of AKI was higher in low birth weight babies. Sluggishness and refusal for feed were most common symptoms. Birth asphyxia and septicemia were the most common early and late cause of AKI. Hyponatremia was the most common electrolyte disturbance. The incidences of AKI, functional renal failure, and intrinsic renal failure were 12%, 48.14%, and 51.85% respectively. CONCLUSIONS AKI is not uncommon in preterm infants. The early recognition and aggressive management of episodes of shock which often precede AKI could be life-saving.

Abstract
In the present study controlled release effervescent buccal discs of buspirone hydrochloride (BS) were designed using HPMC as rate controlling and bioadhesive polymer by direct compression method. Sodium bicarbonate and citric acid were used in varying amounts as effervescence forming agents. Carbon dioxide evolved due to reaction of sodium bicarbonate and citric acid was explored for its potential as buccal permeation enhancer. The designed buccal discs were evaluated for physical characteristics and in vitro drug release studies. Bioadhesive behavior of designed buccal discs was assessed using texture analyzer. In vivo animal studies were performed in rabbits to study bioavailability of BS in the designed buccal discs and to establish permeation enhancement ability of carbon dioxide. It was observed that effervescent buccal discs have faster drug release compared to non-effervescent buccal discs in vitro and effervescent buccal discs demonstrated significant increase in bioavailability of drug when compared to non-effervescent formulation. Hence, effervescent buccal discs can be used as an alternative to improve the drug permeation resulting in better bioavailability. However, the amount of acid and base used for generation of carbon dioxide should be selected with care as this may damage the integrity of bioadhesive dosage form.

Abstract
Obstructive sleep apnea (OSA) is a common type of sleep apnea and is caused by obstruction of upper airway. Sleep apnea is clinically defined as frequent episodes of apnea, hypopnea and symptoms of functional impairment, which could be life-threatening and associated with extreme daytime hyper somnolence, dysfunction, discrements in health-related quality of life, automobile accidents, and cardiovascular morbidity and mortality. Etiopathogenic factors that contribute to OSA include reduced upper-airway dilator muscle activity during sleep, upper-airway anatomical features, ventilatory control insufficiency, lung volume, and rostral fluid shifts. The presence of risk factors such as age, gender and obesity increases the incidence of OSA. The repetitive nocturnal hypoxemia experienced by patients with OSA is associated with activation of a number of neural, humoral, thrombotic, metabolic, and inflammatory disease mechanisms, all of which have also been implicated in the pathophysiology of various systemic diseases. This article summarizes the etiopathogenesis, epidemiology, associated systemic diseases such as cardiovascular diseases, diabetes, and dental diseases with OSA and the influence of tongue on oropharyngeal airway in OSA patients.

Abstract
Objective To compare the efficacy of pharmacoinvasive strategy versus primary percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI). Primary PCI is the preferred treatment for STEMI, but it is not a feasible option for many. A pharmacoinvasive strategy might be a practical solution in the Indian context, although few empirical data exist to guide this approach. Methods This is a prospective, observational, multicentre pilot study. Two hundred consecutive patients with STEMI aged 18–75 years, presenting within 12 h of onset of symptoms and requiring a reperfusion strategy, were studied from five primary PCI capable centres in South India. Patients who opted for pharmacoinvasive strategy (n=45) formed group A. Group B consisted of patients treated with primary PCI (n=155). One patient was lost to follow-up at 1 year. The primary end point was a composite of death, cardiogenic shock, reinfarction, repeat revascularisation of a culprit artery and congestive heart failure at 30 days. Results The primary end point occurred in 11.1% in group A and in 3.9% in group B, p=0.07 (RR=2.87; 95% CI 0.92 to 8.97). The infarct-related artery patency at angiogram was 82.2% in group A and 22.6% in group B (p<0.001). PCI was performed in 73.3% in group A versus 100% in group B (p<0.001), and a thrombus was present in 26.7% in group A versus 63.2% in group B (p<0.001). Failed fibrinolysis occurred in 12.1% in group A. There was no difference in bleeding risk, 2.2% in group A versus 0.6% in group B, (p=0.4). Conclusions This pilot study shows that a pharmacoinvasive strategy can be implemented in patients not selected for primary PCI in India and hints at the possibility of similar outcomes. Larger studies are required to confirm these findings. Trial registration number Trial is registered with Clinical trial registry of India, CTRI number: REF/2011/07/002556.

Abstract
A Gram-stain-negative, rod-shaped, phototrophic bacterium, strain JA793T, was isolated from rhizosphere soil of paddy. The strain was capable of growing phototrophically and chemotrophically. Bacteriochlorophyll-a and carotenoids of the spirilloxanthin series were present as photosynthetic pigments. The major fatty acid of strain JA793T was C18 : 1ω7c/C18 : 1ω6c (>65.7 %), with minor amounts of C16 : 0, C16 : 1ω7c/C16 : 1ω6c, C20 : 2ω6,9c, C16 : 0 3-OH, C14 : 0 and C18 : 0 also present. Ubiquinone-10 and rhodoquinone-10 were present as primary quinones. Phosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine were the major polar lipids, while minor amounts of amino lipids and unidentified lipids were also present. The G+C content of genomic DNA of strain JA793T was 68.7 mol%. 16S rRNA gene-based EzTaxon-e blast search analysis of strain JA793T indicated highest sequence similarity with members of the genus
Rhodoplanes
in the family
Hyphomicrobiaceae
of the class
Alphaproteobacteria
. Strain JA793T had high sequence similarity with
Rhodoplanes elegans
AS130T (98.6 %),
Rhodoplanes roseus
941T (98 %),
Rhodoplanes pokkaliisoli
JA415T (97.5 %) and
Rhodoplanes piscinae
JA266T (97.3 %) and other members of the genus
Rhodoplanes
(<97 %). However, strain JA266T was related by <59 % (based on DNA–DNA hybridization) to
Rhodoplanes elegans
DSM 11907T ( = AS130T),
Rhodoplanes roseus
DSM 5909T ( = 941T),
Rhodoplanes pokkaliisoli
JA415T and
Rhodoplanes piscinae
JA266T. The genomic information was well supported by phenotypic and chemotaxonomic data to classify strain JA793T as a representative of a novel species in the genus
Rhodoplanes
, for which the name Rhodoplanes oryzae sp. nov. is proposed. The type strain is JA793T ( = NBRC 109406T = KCTC 15260T).

Abstract
Two strains (JA746(T) and JA756(T)) having yellowish brown-to-green pigment were isolated from a solar saltern and a pink pond, respectively. While both strains were non-motile and shared the presence of bacteriochlorophyll-a, major cellular fatty acids (C18 : 1ω7c, C16 : 0, C18 : 0), quinone (Q-10), polar lipids and hopanoids, they differed from each other in their carotenoid composition. The G+C content of genomic DNA of strains JA746(T) and 756(T) was 62.4 and 63.3 mol%, respectively. The 16S rRNA gene-based EzTaxon-e blast search analysis of strains JA746(T) and 756(T) indicated highest sequence similarity with members of the genus Rhodovulum in the family Rhodobacteraceae of the class Alphaproteobacteria. Strain JA746(T) has high sequence similarities with Rhodovulum visakhapatnamense JA181(T) (97.3 %), Rhodovulum steppense A-20s(T) (97.3 %), Rhodovulum phaeolacus JA580(T) (97 %), Rhodovulum strictum MB-G2(T) (97 %) and other members of the genus Rhodovulum (<97 %). Strain JA756(T) has high sequence similarities with Rhodovulum visakhapatnamense JA181(T) (99.8 %), Rhodovulum sulfidophilum Hansen W4(T) (99.1 %), Rhodovulum kholense JA297(T) (97.9 %) and other members of the genus Rhodovulum (<97 %). The sequence similarity between strains JA746(T) and JA756(T) was 97.5 %. However, these strains are not closely related to each other or to their phylogenetic neighbours since the DNA-DNA reassociation values were less than 56 %. The genomic information was also supported by phenotypic and chemotaxonomic results, leading us to classify strains JA746(T) ( = NBRC 108898(T) = KCTC 15180(T)) and JA756(T) ( = NBRC 109122(T) = KCTC 15223(T)) as the type strains of two novel species of the genus Rhodovulum, for which the names Rhodovulum salis sp. nov. and Rhodovulum viride sp. nov. are proposed, respectively.

Abstract
An oval to rod-shaped, Gram-stain-negative, phototrophic bacterium, strain JA738T, was isolated from a sediment sample collected from a pink pond. Strain JA738T was non-motile and had vesicular-type intracellular photosynthetic membranes. Bacteriochlorophyll a and carotenoids of the spheroidene series were present as the major photosynthetic pigments. Strain JA738T required thiamine and pantothenate for growth. The major cellular fatty acids were C18 : 1ω7c, C18 : 1ω5c, C18 : 0 and C18 : 1ω7c11-methyl; minor amounts of C10 : 0 3-OH and C16 : 0 were also present. The major quinone was Q-10 and major polar lipids were phosphatidylglycerol, phosphatidylethanolamine and two unidentified sulfolipids (SL1–2). Phylogenetic analysis on the basis of 16S rRNA gene sequences showed that strain JA738T clustered with species of the genus
Rhodovulum
in the class
Alphaproteobacteria
. Strain JA738T was most closely related to
Rhodovulum adriaticum
DSM 2781T (96.4 % 16S rRNA gene sequence similarity) and other members of the genus
Rhodovulum
(<96.1 %). On the basis of phenotypic and molecular genetic evidence, it is proposed that strain JA738T should be classified as a novel species of the genus
Rhodovulum
for which the name Rhodovulum bhavnagarense sp. nov. is proposed. The type strain is JA738T ( = DSM 24766T = KCTC 15110T).

Abstract
A Gram-stain-positive, oxidase-negative, starch-hydrolysing, actinobacterium (strain JC82T) was isolated from a soda lake in Lonar, India. Based on 16S rRNA gene sequence similarity studies, strain JC82T belonged to the genus
Georgenia
and was most closely related to
Georgenia muralis
1A-CT (96.8 %) and other members of the genus
Georgenia
(<96.5 %). The DNA G+C content of strain JC82T was 73.4 mol%. The cell-wall amino acids were alanine, glutamic acid and lysine with peptidoglycan type A4α. Polar lipids included diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannosides, an unidentified lipid (L1) and an unidentified glycolipid (GL3). The predominant isoprenoid quinone was menaquinone MK-8(H4). Anteiso-C15 : 0 was the predominant fatty acid and significant proportions of iso-C14 : 0, C14 : 0, C16 : 0, iso-C15 : 0 and iso-C16 : 0 were also detected. Strain JC82T produced thermostable alkaline amylase. The results of physiological and biochemical tests allowed a clear phenotypic differentiation of strain JC82T from all other members of the genus
Georgenia
. Based on these data, strain JC82T represents a novel species of the genus
Georgenia
, for which the name Georgenia satyanarayanai sp. nov. is proposed. The type strain is JC82T ( = KCTC 19802T = NBRC 107612T).

Abstract
In this research, we investigated the toxicity responses of rat following a continuous 4 h inhalation exposure of only the head and nose to iron oxide nanoparticles (Fe(3)O(4) NPs, size = 15-20 nm). The rats for the investigation were exposed to a concentration of 640 mg/m(3) Fe(3)O(4) NPs. Markers of lung injury and proinflammatory cytokines (interleukin-1β, tumor necrosis factor-α, and interleukin-6) in bronchoalveolar lavage fluid (BALF) and blood, oxidative stress in lungs, and histopathology were assessed on 24 h, 48 h, and 14 days of postexposure periods. Our results showed a significant decrease in the cell viability, with the increase in the levels of lactate dehydrogenase, total protein, and alkaline phosphatase in the BALF. Total leukocyte count and the percentage of neutrophils in BALF increased within 24 h of postexposure. Immediately following acute exposure, rats showed increased inflammation with significantly higher levels of lavage and blood proinflammatory cytokines and were consistent throughout the observation period. Fe(3)O(4) NPs exposure markedly increased malondialdehyde concentration, while intracellular reduced glutathione and antioxidant enzyme activities were significantly decreased in lung tissue within 24-h postexposure period. On histological observation, the lung showed an early activation of pulmonary clearance and a size-dependant biphasic nature of the Fe(3)O(4) NPs in causing the structural alteration. Collectively, our data illustrate that Fe(3)O(4) NPs inhalation exposure may induce cytotoxicity via oxidative stress and lead to biphasic inflammatory responses in Wistar rat.

Abstract
The aim of the present study was to assess the acute toxic potential of cerium oxide nanoparticles (CeO(2) NPs) in rats when exposed through the head and nose inhalation route. The rats were exposed to CeO(2) NPs and the resultant effects if any, to cause cytotoxicity, oxidative stress and inflammation in the lungs were evaluated on a 24h, 48h and 14 day post exposure period. Our results showed a significant decrease in the cell viability, with the increase of lactate dehydogenase, total protein and alkaline phosphatase levels in the bronchoalveolar lavage fluid (BALF) of the exposed rats. Total leukocyte count and the percentage of neutrophils in BALF were elevated within 24h of post exposure. The concentrations of pro-inflammatory cytokines (IL-1β, TNF-α, and IL-6) were significantly increased in the BALF and in the blood throughout the observation period. The level of malondialdehyde was elevated with the decreased levels of intracellular reduced glutathione (GSH) in the lung after exposure. The alveolar macrophages (AMs) and neutrophils overloaded with phagocytosed CeO(2) NPs were observed along with non-phagocytosed free CeO(2) NPs that were deposited over the epithelial surfaces of the bronchi, bronchiole and alveolar regions of lungs within 24h of post exposure and were consistent throughout the observation period. A well distributed, multifocal pulmonary microgranulomas due to impairment of clearance mechanism leading to biopersistence of CeO(2) NPs for an extended period of time were observed at the end of the 14 day post exposure period. These results suggest that acute exposure of CeO(2) NPs through inhalation route may induce cytotoxicity via oxidative stress and may lead to a chronic inflammatory response.

Abstract
OBJECTIVE To analyze the efficacy and safety of indigenous Tenecteplase in Indian elderly STEMI patients in a clinical setting. METHODS Post-licensure, observational, prescription event monitoring (PEM) study. RESULTS 2162 patients received weight-adjusted Tenecteplase injection. The data for elderly (> 60 years) and non-elderly (< or = 60 years) was identified, segregated and compared. Out of 2162 patients, 805 were elderly patients and 1357 were non-elderly. Clinically successful thromolysis was seen in 83.98% of elderly and 86% of non-elderly group (p = 0.22). There was no significant difference in percentage of patients reporting bleeding, stroke, intracranial hemorrhage, myocardial reinfraction, ventricular tachyarrhythmia between the groups. Mortality was significantly (p = < 0.0001) more in elderly (6.21%) than non-elderly (2.06%) patients. CONCLUSION The indigenously developed Tenecteplase shows high efficacy and safety in its in-hospital use in Indian elderly patients with STEMI.

Abstract
As an alternative to the standard Draize eye irritation test, the potential irritancy of compounds was evaluated by observing adverse changes that occur in chorioallantoic membrane CAM) of the hen egg (HECAM) after exposure to a test chemical placed directly on the CAM. The occurrence of hemorrhage, coagulation, and lysis in response to a test compound is the basis for employing this technique to evaluate its potential for in vivo damage to mucous membrane, in particular the eye. Irritancy is scored according to the severity and speed at which damage occurs. In the present study, five different classes of pesticides were screened for irritation potential. There was good correlation between the HECAM assay and the in vivo Draize eye irritation test. The proposed HECAM assay, which reduces the requirement for laboratory animals, could be a painless alternative to the Draize test.

Abstract
A prospective study was undertaken on suspected lymph node TB (LNTB) patients, to evaluate the diagnostic utility of mycobacterial culture of fine needle aspirate (FNA), in comparison with the cytological examination and acid fast staining. Eighty percent of 157 aspirates studied were positive by cytological examination; 18% by ZN smear and 45% were positive by culture. Twelve aspirates which were negative by cytological features yielded positive mycobacterial cultures; four out of these were from HIV positive patients. Our observations suggest that supplementing FNA cytology with mycobacterial culture would increase the sensitivity of diagnosing LNTB; in addition to giving a highly specific diagnosis.

Abstract
OBJECTIVE To compare the efficacy and safety of a S-metoprolol extended release (ER) tablet (50 mg) versus a racemate metoprolol ER tablet (100 mg) in the management of angina. METHODS An open-label, prospective, comparative study in a clinical setting was conducted in Indian patients. Patients (n = 50 in each group) with a history of angina pectoris, with or without hypertension, were administered study medications in a sequential 1:1 manner once daily for 8 weeks. The primary efficacy variable was a mean change from baseline in the number of angina attacks. The secondary efficacy variables were: mean change from baseline in the proportion of patients with no angina attacks, systolic blood pressure, diastolic blood pressure, heart rate, and proportion of blood pressure responders. Number of patients reporting adverse effects (AEs) and severity of AEs in both of the groups were compared. RESULTS All patients (n = 100) completed the study. In the S-metoprolol group the number of angina attacks (mean +/- SEM) at baseline and after 2, 4 and 8 weeks of therapy were 6.3 +/- 0.8, 3 +/-0.4, 1.8 +/- 0.4 and 0.7 +/- 0.2, respectively. In the metoprolol group these values were 5.8 +/-1, 3 +/- 0.7, 1.4 +/- 0.3 and 0.7 +/- 0.2, respectively. The reduction in the number of angina attacks from baseline was significant (p < 0.0001) in both groups with no between-group difference. The response rate in angina (percentage of patients completely relieved of angina attacks clinically) was greater in the S-metoprolol group (72%) when compared to the metoprolol group (62%) (p > 0.05, NS). Both study groups showed significant (p < 0.0001) reduction in baseline systolic blood pressure (SBP), diastolic blood pressure (SBP) and heart rate (HR) in hypertensive patients and a clinically non-significant (p > 0.05, NS) change in normotensive patients. Among hypertensive patients, the response rate in angina was higher in the S-metoprolol group (74%) when compared to the metoprolol group (61%) (p > 0.05, NS). In the S-metoprolol group four patients reported AEs: fatigue (n = 4), dry mouth (n = 1), dizziness (n = 1), dyspnea (n = 2), and mild rash (n = 1). In the metoprolol group three patients reported AEs: fatigue (n = 2), dyspnea (n = 1) and dizziness (n = 1). No statistically significant difference was detected between the groups in AE frequency/severity. CONCLUSION In routine clinical practice in the management of angina (with or without coexisting hypertension), S-metoprolol administered at half the dose of the racemate, shows similar efficacy, safety and a trend towards a higher response rate.

Abstract
Dihydroxyacetone (Dha) kinases are a family of sequence-conserved enzymes which utilize either ATP (in animals, plants and eubacteria) or phosphoenolpyruvate (PEP, in eubacteria) as their source of high-energy phosphate. The kinases consist of two domains/subunits: DhaK, which binds Dha covalently in hemiaminal linkage to the Nepsilon2 of a histidine, and DhaL, an eight-helix barrel that contains the nucleotide-binding site. The PEP-dependent kinases comprise a third subunit, DhaM, which rephosphorylates in situ the firmly bound ADP cofactor. DhaM serves as the shuttle for the transfer of phosphate from the bacterial PEP: carbohydrate phosphotransferase system (PTS) to the Dha kinase. The DhaL and DhaK subunits of the PEP-dependent Escherichia coli kinase act as coactivator and corepressor of DhaR, a transcription factor from the AAA(+) family of enhancerbinding proteins. In Gram-positive bacteria genes for homologs of DhaK and DhaL occur in operons for putative transcription factors of the TetR and DeoR families. Proteins with the Dha kinase fold can be classified into three families according to phylogeny and function: Dha kinases, DhaK and DhaL homologs (paralogs) associated with putative transcription regulators of the TetR and DeoR families, and proteins with a circularly permuted domain order that belong to the DegV family.

Abstract
A number of genes similar to mammalian Class III nucleotide cyclases are found in mycobacteria, and biochemical characterization of some of these proteins has indicated that they code for adenylyl cyclases, with properties similar to the mammalian enzymes. Our earlier bioinformatic analysis had predicted that the Rv1120c gene in Mycobacterium tuberculosis is a pseudogene, while analysis of the genome of Mycobacterium avium indicated the presence of a functional ortholog. We therefore cloned and expressed Rv1120c and its ortholog from M. avium, Ma1120, in Escherichia coli, and find that while the protein from M. tuberculosis is misfolded and found in inclusion bodies, Ma1120 is expressed to high levels as a functional adenylyl cyclase. Sequence analysis of Ma1120 indicates interesting variations in critical amino acids that are known to be important for catalytic activity. Ma1120 is maximally active in the presence of MnATP as substrate ((app)Km approximately 400 microM), and is inhibited by P-site inhibitors (IC50 of 2',5'-dideoxy-3'-adenosine triphosphate approximately 730 nM) and tyrphostins (IC50 approximately 36 microM) in a manner similar to the mammalian enzymes. This therefore represents the first Class III cyclase biochemically characterized from M. avium, and the absence of a functional ortholog in M. tuberculosis suggests a unique role for this enzyme in M. avium.

Abstract
Acute hemodynamic effects of high flow oxygen (O2) inhalation, sublingual isosorbide dinitrate (ISDN), intravenous aminophylline (AMN) and sublingual nifedipine (NIF) were studied in 32 patients with primary pulmonary hypertension (PPH). In 30 out of 32 patients the basal ratio of pulmonary to systemic vascular resistance (Rp/Rs) was > 0.5 (mean = 0.77 +/- 0.20). Oxygen caused significant decrease in the mean resistance ratio to 0.68 +/- 0.20 (p = 0.005). ISDN, AMN and NIF caused increase in the resistance ratio to 0.79 +/- 0.26; 0.78 +/- 0.26; and 0.80 +/- 0.23 respectively. O2, ISDN, AMN and NIF caused a fall of Rp/Rs in 21 (65.6%), 10 (31.2%), 10(31.2%) and 9(28.1%) patients respectively. Thus, of the four drugs tested high flow O2 inhalation resulted in fall of Rp/Rs in two thirds of patients whereas ISDN, AMN and NIF caused a mean rise in Rp/Rs. One third of patients did respond acutely to the latter three drugs. Acute hemodynamic studies are useful before prescribing vasodilators in patients with PPH since more of the commonly used drugs like ISDN, AMN, NIF could have detrimental hemodynamic responses in some patients. However, great caution should be exercised before performing hemodynamic study as the procedure has definite mortality and morbidity.
