Abstract
BACKGROUND The Manyata program is a quality improvement initiative for private healthcare facilities in India which provided maternity care services. Under this initiative, technical assistance was provided to selected facilities in the states of Uttar Pradesh, Jharkhand and Maharashtra which were interested in obtaining 'entry level certification' under the National Accreditation Board for Hospitals and Healthcare Providers (NABH) for provision of quality services. This paper describes the change in quality at those Manyata-supported facilities when assessed by the NABH standards of care. METHODS Twenty-eight private-sector facilities underwent NABH assessments in the three states from August 2017 to February 2019. Baseline assessment (by program staff) and NABH assessment (by NABH assessors) findings were compared to assess the change in quality of care as per NABH standards of care. The reported performance gaps from NABH assessments were then also classified by thematic areas and suggested corrective actions based on program implementation experience. RESULTS The overall adherence to NABH standards of care improved from 9% in the baseline assessment to 80% in the NABH assessment. A total of 831 performance gaps were identified by the NABH assessments, of which documentation issues accounted for a majority (70%), followed by training (19%). Most performance gaps could be corrected either by revising existing documentation or creating new documentation (62%), or by orienting facility staff on various protocols (35%). CONCLUSION While the adherence of facilities to the NABH standards of care improved considerably, certain performance gaps remained, which were primarily related to documentation of facility policies and protocols and training of staff, and required corrective actions for the facilities to achieve NABH entry level certification.

Abstract
BACKGROUND In India, more than 60% of hospital beds are in private facilities, yet several studies have observed suboptimal quality of care in private facilities. We aimed to understand the role of Manyata, a quality improvement initiative in private facilities focused on mentorship and clinical standards, to improve the knowledge and skills of health care providers, their adherence to key childbirth-related clinical practices, and health outcomes for women and newborns. METHODS We conducted a secondary analysis of Manyata program data collected from 466 private facilities across 3 states (Jharkhand, Maharashtra, and Uttar Pradesh) in India from October 2016 to February 2019. We calculated means and 95% confidence intervals for knowledge and skills assessment, adherence to facility standards was analyzed by calculating the proportion of facilities passing a given quality standard at baseline and endline, and changes in pregnancy outcomes were assessed with autoregression modeling. RESULTS From assessments conducted before and after training among providers in Manyata, we observed a significant increase in average knowledge score (6.3 vs. 13.2 of 20) and skill score (8.0 vs. 34.3 of 40). Overall, a significant increase occurred in adherence to clinical standards between baseline and endline assessments (29% vs. 93%). The standards with the greatest improvements were identification and management of eclampsia/preeclampsia, postpartum hemorrhage, and neonatal resuscitation. There were no significant changes over time in absolute rate of reported complications; however, referral rates from private facilities for preeclampsia and newborn sepsis identification and management declined. CONCLUSION Our analysis indicates private facilities' adherence to quality standards and nurses' childbirth knowledge and practical skills increased during Manyata. Additional efforts are needed to ensure high-quality care during cesarean deliveries at private facilities. Future studies with rigorous design are required to evaluate the impact of this quality improvement initiative in improving pregnancy outcomes.

Abstract
Background The Breast Health Initiative (BHI) was launched to demonstrate a scalable model to improve access to early diagnosis and treatment of breast cancer. Methods A package of evidence‐based interventions was codesigned and implemented with the stakeholders, as part of the national noncommunicable disease program, through the existing primary health care system. Data from the first 18 months of the BHI are presented. Results A total of 108,112 women received breast health education; 48% visited the health facilities for clinical breast examination (CBE), 3% had a positive CBE result, and 41% were referred to a diagnostic facility. The concordance of CBE findings between health care providers and adherence to follow‐up care improved considerably, with more women visiting the diagnostic facilities and completing diagnostic evaluation within 1 month from initial screening, and with only 9% lost to follow‐up. The authors observed a clinically meaningful decrease in time to complete diagnostic evaluation with biopsy, from 37 to 9 days. Conclusions The results demonstrate the feasibility and effectiveness of implementing a large‐scale, decentralized breast cancer early detection program delivered through the existing primary health care system in India. This article presents the key strategies, interventions, and results from the first 18 months of the large‐scale, decentralized breast cancer early detection program in a real‐world setting in India.

Abstract
Psoriatic Erythroderma (PsE) is a presentation of Erythroderma due to a history of psoriasis showing inflammation and exfoliation of epidermal skin characterized by erythema and scaling. There is no definite treatment in contemporary medical science but the principle-based Ayurvedic approach has been proved to be effective. We present a case of PsE treated for 3 months with Ayurvedic herbomineral preparations and dietary restrictions for non-vegetarian and dairy items. As per the Ayurvedic diagnostic view, the presented case is correlated with Audumbara Kushtha and Ekakushtha due to their intricate features. Thus, Ayurvedic approaches were directed to eliminate vitiated doshas responsible for acute exacerbation of Kushtha (∼dermatitis) and to maintain equilibrium among them. The patient was initially considered as a case of Saam stage of Kushtha with Pitta-Rakta-Vata predominance. Thus, management was planned into different domains-treatment of Saam stage of Kushtha, Vyadhipratyanika chikitsa (∼disease antagonistic treatment), Rasayana intervention (∼Immunomodulation therapy) and Ayurvedic drugs were given accordingly. The assessment was done based on subjective parameters and PASI score. The patient was followed for about one and half year without any complication and relapse. This case study shows PsE can be managed with an Ayurvedic approach and proper diet planning.

Abstract
BACKGROUND Recent reports from this lab have demonstrated a higher incidence of NETs, nitrosative, as well as oxidative stress, and have a direct correlation with the severity of sepsis and organ damage. However, the mechanistic perspective of NETs induced organ damage has not been understood at the cellular and molecular level. Interaction of inducible nitric oxide synthase (iNOS) with Rac2 in regulating reactive oxygen species (ROS) and reactive nitrogen species (RNS) generation and its implications in microbial killing has been reported. This study was, therefore, undertaken in neutrophils of sepsis patients to investigate the functional importance of iNOS-Rac2 interaction in ROS/ RNS, peroxynitrite generation, NETs generation, and NETs mediated cell death. METHODS The study was conducted on 100 patients with sepsis and 50 healthy volunteers. Interaction between iNOS and Rac2 was performed using co-immunoprecipitation and co-immunolabeling assay. Free radicals involving ROS and RNS were evaluated using cytochrome c reduction assay. NETs formation was evaluated by fluorescence microscopy. The cytotoxic effect of NETs was assessed on lung carcinoma cell line (A549) using colorimetric Alamar blue assay. RESULTS Enhanced interaction between iNOS and Rac2 was found in sepsis neutrophils in comparison with control. This was accompanied by an increased level of superoxide (O2.-), nitric oxide (NO), and peroxynitrite (ONOO-) which were decreased in the presence of NAC, DPI, and 1400 W, signifying the role of iNOS-Rac2 interaction. Enhanced NETs release from activated sepsis neutrophils were abrogated in the presence of DPI. NETs from sepsis neutrophils exert a cytotoxic effect on lung epithelial cells (A549) in a concentration-dependent manner. CONCLUSION Our findings exhibit the functional role of iNOS-Rac2 interaction in ROS/RNS, peroxynitrite generation, NETs generation, and NETs mediated cell death.

Abstract
Raja Ramanna Centre for Advanced Technology (RRCAT) has an ongoing program to develop 650 MHz, 5-cell elliptical superconducting RF (SCRF) cavities under the Indian Institutes and Fermilab Collaboration. The elliptical multi-cell SCRF cavity fabrication process involves forming of half-cells and their precise machining and joining by electron beam welding to form end groups and dumbbells, which are then joined to make the final cavity. To ensure that the final welded cavity achieves physical lengths and resonant frequencies within design tolerance and has good field flatness, the measurement and correction of resonant frequency are carried out for dumbbells and end groups. A novel method to identify the frequency of individual half-cells in a dumbbell cavity and a dedicated tuning fixture to correct them had been developed. The paper details the RF characterization and correction procedure employed during fabrication of the first six 650 MHz cavities at RRCAT.

Abstract
COVID 19 has been declared a Public Health Emergency of International Concern by the WHO (1). The management of COVID 19 pandemic by Govt. of India has been applauded by the WHO for its timely and strict actions. No doubt we have borrowed time from the lockdown but it could have been utilized in a much better way to control. The epidemiological opinion is that the harshest lockdown was acceptable but its extension was not required as we have not been able to sustain the benefits of lockdown gained in the beginning. The gain of lockdown could have been better had it been coupled with meticulous contact tracing and containment measures during the early period of pandemic. A subsequent failure to ensure all these together resulted in spread of virus everywhere in spite of lockdown. It has also given a false feeling to the public that lockdown will prevent infection.

Abstract
The present study provides evidence of a unique function of RGG1 in providing salinity stress tolerance in transgenic rice without affecting yield. It also provides a good example for signal transduction from the external environment to inside for enhanced agricultural production that withstands the extreme climatic conditions and ensures food security. The role of heterotrimeric G-proteins functioning as signalling molecules has not been studied as extensively in plants as in animals. Recently, their importance in plant stress signalling has been emerging. In this study, the function of rice G-protein γ subunit (RGG1) in the promotion of salinity tolerance in rice (Oryza sativa L. cv. IR64) was investigated. The overexpression of RGG1 driven by the CaMV35S promoter in transgenic rice conferred high salinity tolerance even in the presence of 200 mM NaCl. Transcript levels of antioxidative genes, i.e., CAT, APX, and GR, and their enzyme activities increased in salinity-stressed transgenic rice plants suggesting a better antioxidant system to cope the oxidative-damages caused by salinity stress. The RGG1-induced signalling events that conferred tolerance to salinity was mediated by increased gene expression of the enzymes that scavenged reactive oxygen species. In salinity-stressed RGG1 transgenic lines, the transcript levels of RGG2, RGB, RGA, DEP1, and GS3 also increased in addition to RGG1. These observations suggest that most likely the stoichiometry of the G-protein complex was not disturbed under stress. Agronomic parameters, endogenous sugar content (glucose and fructose) and hormones (GA3, zeatin and IAA) were also higher in the transgenic plants compared with the wild-type plants. A BiFC assay confirmed the interaction of RGG1 with different stress-responsive proteins which play active roles in signalling and prevention of aggregation of proteins under stress-induced perturbation. The present study will help in understanding the G-protein-mediated stress tolerance in plants.

Abstract
Myasthenia gravis is a disease of great challenge to the anesthesiologist, because it affects the neuromuscular junction. Anesthetic management involves either muscle relaxant or non-muscle relaxant techniques. This case report documents the safe use of fentanyl, propofol and sevoflurane combination guided by bispectral index, without the use of muscle relaxants in a patient with myasthenia gravis who presented for meningioma surgery.

Abstract
The Western Ghats (WG) of India, one of the hottest biodiversity hotspots in the world, has witnessed major land-use and land-cover (LULC) change in recent times. The present research was aimed at studying the patterns of LULC change in WG during 1985-1995-2005, understanding the major drivers that caused such change, and projecting the future (2025) spatial distribution of forest using coupled logistic regression and Markov model. The International Geosphere Biosphere Program (IGBP) classification scheme was mainly followed in LULC characterization and change analysis. The single-step Markov model was used to project the forest demand. The spatial allocation of such forest demand was based on the predicted probabilities derived through logistic regression model. The R statistical package was used to set the allocation rules. The projection model was selected based on Akaike information criterion (AIC) and area under receiver operating characteristic (ROC) curve. The actual and projected areas of forest in 2005 were compared before making projection for 2025. It was observed that forest degradation has reduced from 1985-1995 to 1995-2005. The study obtained important insights about the drivers and their impacts on LULC simulations. To the best of our knowledge, this is the first attempt where projection of future state of forest in entire WG is made based on decadal LULC and socio-economic datasets at the Taluka (sub-district) level.

Abstract
KEY MESSAGE PsSEOF-1 binds to calcium and its expression is upregulated by salinity treatment. PsSEOF - 1 -overexpressing transgenic tobacco showed enhanced salinity stress tolerance by maintaining cellular ion homeostasis and modulating ROS-scavenging pathway. Calcium (Ca(2+)) plays important role in growth, development and stress tolerance in plants. Cellular Ca(2+) homeostasis is achieved by the collective action of channels, pumps, antiporters and by Ca(2+) chelators present in the cell like calcium-binding proteins. Forisomes are ATP-independent mechanically active motor proteins known to function in wound sealing of injured sieve elements of phloem tissue. The Ca(2+)-binding activity of forisome and its role in abiotic stress signaling were largely unknown. Here we report the Ca(2+)-binding activity of pea forisome (PsSEO-F1) and its novel function in promoting salinity tolerance in transgenic tobacco. Native PsSEO-F1 promoter positively responded in salinity stress as confirmed using GUS reporter. Overexpression of PsSEO-F1 tobacco plants confers salinity tolerance by alleviating ionic toxicity and increased ROS scavenging activity which probably results in reduced membrane damage and improved yield under salinity stress. Evaluation of several physiological indices shows an increase in relative water content, electrolyte leakage, proline accumulation and chlorophyll content in transgenic lines as compared with null-segregant control. Expression of several genes involved in cellular homeostasis is perturbed by PsSEO-F1 overexpression. These findings suggest that PsSEO-F1 provides salinity tolerance through cellular Ca(2+) homeostasis which in turn modulates ROS machinery providing indirect link between Ca(2+) and ROS signaling under salinity-induced perturbation. PsSEO-F1 most likely functions in salinity stress tolerance by improving antioxidant machinery and mitigating ion toxicity in transgenic lines. This finding should make an important contribution in our better understanding of the significance of calcium signaling in phloem tissue leading to salinity stress tolerance.

Abstract
Lectin receptor-like kinases (LecRLKs) are members of RLK family composed of lectin-like extracellular recognition domain, transmembrane domain and cytoplasmic kinase domain. LecRLKs are plasma membrane proteins believed to be involved in signal transduction. However, most of the members of the protein family even in plants have not been functionally well characterized. Herein, we show that Pisum sativum LecRLK (PsLecRLK) localized in plasma membrane systems and/or other regions of the cell and its transcript upregulated under salinity stress. Overexpression of PsLecRLK in transgenic tobacco plants confers salinity stress tolerance by alleviating both the ionic as well the osmotic component of salinity stress. The transgenic plants show better tissue compartmentalization of Na(+) and higher ROS scavenging activity which probably results in lower membrane damage, improved growth and yield maintenance even under salinity stress. Also, expression of several genes involved in cellular homeostasis is perturbed by PsLecRLK overexpression. Alleviation of osmotic and ionic components of salinity stress along with reduced oxidative damage and upregulation of stress-responsive genes in transgenic plants under salinity stress conditions could be possible mechanism facilitating enhanced stress tolerance. This study presents PsLecRLK as a promising candidate for crop improvement and also opens up new avenue to investigate its signalling pathway.

Abstract
OBJECTIVE To investigate the incidence of Nosocomial Infection (NI) and type of bacteriological isolates among the patients admitted in the medical and surgical wards of a non-teaching secondary care hospital in north India. MATERIALS AND METHODS This was a cross-sectional hospital based study conducted in the Wards of General Medicine, General Surgery and Orthopaedic of the hospital. The patient were admitted in the department for various surgical procedures, without evidence of initial infection, were included in the study. RESULTS A total of 176 patients were included in the study of which 82 were from Medical and 94 from Surgical ward. Overall incidence of NI was found to be 26.1% (Medical ward=28%, Surgical ward=24.5%., p=0.58). The isolation rate of Acinetobacter baumanii was (p=0.15) higher among the patients of medical ward (95.7%) than surgical ward (82.6). Escherichia coli was isolated in 89.1% and no significant difference was observed between medical and surgical wards. Klebsiella pneumoniae was isolated in 50% patients and was almost similar (p=0.37) in medical surgical wards. The isolation rate of Pseudomonos aeruginosa, Enterococcus faecalis, Staphylococcus aureus and Coagulase negative staphylococci were 43.5%, 73.9%, 34.8% and 17.4% respectively. A significant difference was observed in the isolation rate of Enterococcus faecalis (p=0.007) and Coagulase negative staphylococci (p=0.002) between medical and surgical wards. Overall, among the patients who developed NI, 27.2% patient's bacterial isolates were Gram positive (Surgical=64.1, Medical=80%). CONCLUSION The incidence of NI is increasing in the hospitals, so extensive that more care has to be taken in cleaning the wards of the hospitals.

Abstract
PsSEOF1, a SEO (sieve element occlusion) gene family protein (forisome) is calcium powered motor protein and is located close to plasma membrane of sieve element. In sieve element (SE) it senses the calcium ion levels and undergoes ATP-independent conformational shifts. Forisome, meaning gate-bodies (Latin foris: wing of a gate; Greek soma: body). Recent reports show that SEO gene family protein can prevent the loss of nutrient rich photoassimilate upon wound injury. The regulation of SEO protein forisome under abiotic/ biotic stress is still unknown. The analysis of cis-regulatory element present in the upstream region is not well understood. Tissue specific promoters guarantee correct expression when it perceives particular stimuli. Here we report isolation of tissue specific promoter of PsSEOF1 was isolated by gene walking PCR from P. sativum (pea) genomic DNA library constructed by BD genome walker kit. In silico analysis revealed several putative cis element within this promoter sequence like wound response, cold, dehydration. Putative elements which might be required for its vascular tissue specificity has also been identified. The GUS activities of PsSEOF1 promoter-GUS chimeric construct in the agroinfiltrated leaves under different environmental stress abiotic and biotic like wound, cold, salt and phytohormones has shown high level of GUS activity. To identify the activity of PsSEOF1 promoter under different stress condition an Agrobacterium-mediated transient expression of tobacco plants were subjected to histochemical GUS staining. Stress-inducible nature of PsSEOF1 promoter opens possibility for the study of the PsSEOF1 gene regulation under stress condition. The isolated promoter sequence could serve as an important candidate for tissue specific promoter in genetic engineering of plant under stress conditions.

Abstract
Forisomes protein belongs to SEO gene family and is unique to Fabaceae family. These proteins are located in sieve tubes of phloem and function to prevent loss of nutrient-rich photoassimilates, upon mechanical injury/wounding. Forisome protein is also known as ATP independent, mechanically active proteins. Despite the wealth of information role of forisome in plants are not yet fully understood. Recent reports suggest that forisomes protein can act as ideal model to study self assembly mechanism for development of nanotechnological devices like microfluidic system application in space exploration mission. Improvement in micro instrument is highly demanding and has been a key technology by NASA in future space exploration missions. Based on its physical parameters, forisome are found to be ideal biomimetic materials for micro fluidic system because the conformational shifts can be replicated in vitro and are fully reversible over large number of cycles. By the use of protein engineering forisome recombinant protein can be tailored. Due to its unique ability to convert chemical energy into mechanical energy forisome has received much attention. For nanotechnological application and handling biomolecules such as DNA, RNA, protein and cell as a whole microfluidic system will be the most powerful technology. The discovery of new biomimetic smart materials has been a key factor in development of space science and its requirements in such a challenging environment. The field of microfludic, particularly in terms of development of its components along with identification of new biomimetic smart materials, deserves more attention. More biophysical investigation is required to characterize it to make it more suitable under parameters of performance.

Abstract
An efficient method for in vitro micro propagation and genetic transformation of plants are crucial for both basic and applied research. Maize is one of the most important cereal crops around the world. Regeneration from immature embryo is hampered due to its unavailability round the year. On the contrary mature embryo especially tropical maize is recalcitrant toward tissue culture. Here we report a highly efficient regeneration (90%) system for maize by using 2 different approaches i.e., embryogenic and organogenic callus cultures. Seeds were germinated on MS medium supplemented with 5 mg/l 2,4-D and 3 mg/l BAP. Nodal regions of 2 wks old seedlings were longitudinally split upon isolation and subsequently placed on callus initiation medium. The maximum frequency of embryogenic callus formation (90%) was obtained on MS medium supplemented with 2 mg/l 2,4-D and 1 mg/l BAP in the dark conditions. The compact granular organogenic callus formation (85% frequency) was obtained on MS medium supplemented with 2.5 mg/l 2,4-D and 1.5 mg/l BAP at light conditions. MS medium supplemented with 2 mg/l BAP, 1 mg/l Kinetin and 0.5 mg/l NAA promoted the highest frequency of shoot induction. The highest frequency of root formation was observed when shoots were grown on MS medium. The regenerated plants were successfully hardened in earthen pots after adequate acclimatization. The important advantage of this improved method is shortening of regeneration time by providing an efficient and rapid regeneration tool for obtaining more stable transformants from mature seeds of Indian tropical maize cultivar (HQPM-1).

Abstract
Forisomes are ATP independent, mechanically active proteins from the Fabaceae family (also called Leguminosae). These proteins are located in sieve tubes of phloem and function to prevent loss of nutrient-rich photoassimilates, upon mechanical injury/wounding. Forisomes are SEO (sieve element occlusion) gene family proteins that have recently been shown to be involved in wound sealing mechanism. Recent findings suggest that forisomes could act as an ideal model to study self assembly mechanism for the development of nanotechnological devices like microinstruments, the microfluidic system frequently used in space exploration missions. Technology enabling improvement in micro instruments has been identified as a key technology by NASA in future space exploration missions. Forisomes are designated as biomimetic smart materials which are calcium-energized motor proteins. Since forisomes are biomolecules from plant systems it can be doctored through genetic engineering. In contrast, "smart" materials which are not derived from plants are difficult to modify in their properties. Current levels of understanding about forisomes conformational shifts with respect to calcium ions and pH changes requires supplement of future advances with relation to its 3D structure to understand self assembly processes. In plant systems it forms blood clots in the form of occlusions to prevent nutrient fluid leakage and thus proves to be a unique damage control system of phloem tissue.

Abstract
BACKGROUND Corneal scars are commonly formed following many diseases of the eye like trauma, inflammation and infections. They lead to permanent diminution of vision which can be managed by Penetrating Keratoplasty (PK). PK is removing diseased as well as healthy tissues and is associated with many post-operative complications. Deep Anterior Lamellar Keratoplasty (DALK) is a relatively newer procedure which replaces only the diseased stroma, leaving the original corneal endothelium intact. This procedure is associated with lesser incidence of post-operative complications. METHODS The study was conducted at a large tertiary care centre. 10 patients with stromal corneal scars were subjected to DALK and results were analysed after 06 months. Poor quality donor corneal tissue of B- and C grade was used in all cases. RESULTS 7 out of 10 patients (70%) undergoing DALK had post-operative visual acuity of 6/24 or better. 03 patients who did not have adequate recovery of visual acuity were due to over-riding of the graft in 01 case (10%), fungal keratitis in 01 case (10%) and interface haze in 01 case (10%). CONCLUSION DALK is a promising new technique for management of superficial corneal stromal scars using poor quality donor corneal tissue. Initial results are encouraging with minimal complications.

Abstract
Penetrating injuries of the anterior fontanelle are exceedingly uncommon and are most often associated with inflictedinjury. This report of a 7-month-old male infant, whose father was working with a knife which accidentally slipped from his hand and penetrated the infants anterior fontanelle and frontal lobe, demonstrates that accidental injuries may also occur rarely.

Abstract
OBJECTIVES To study the knowledge and practices related to newborn care in urban slums of Lucknow city, UP, and to identify critical behaviors, practices, and barriers that influence the survival of newborns. MATERIALS AND METHODS A cross-sectional study in urban slums of Lucknow city, UP, included 524 women who had a live birth during last 1 year preceding data collection. Data were analyzed using statistical software SPSS 10.0 for windows. RESULTS Study findings showed that about half of the deliveries took place at home. Majority (77.1%) of the mothers believed that baby should be bathed with warm water and dried with clean cloth and 79.7% mothers practiced it. Only 36.6% mothers initiated breast-feeding within 1 h of birth and 30.2% initiated after 1 day. The mothers who have not given colostrum to their baby, in majority the reason was customs. CONCLUSION In majority of cases, correct knowledge and correct practices regarding newborn care were lacking among mothers and this should be promoted through improved coverage with existing health services.

Abstract
Kisspeptin, as well as insulin-like growth factor-1 (IGF-1), act centrally to stimulate luteinizing hormone-releasing hormone (LHRH) secretion at puberty. IGF-1 can induce KiSS-1 gene expression as an early pubertal event; however, the signaling pathway mediating this effect is not known. Since alcohol (ALC) blocks IGF-1 induced LHRH release acutely, we assessed whether this drug could affect IGF-1 stimulated prepubertal KiSS-1 gene expression following a binge type of exposure. Immature female rats were administered either ALC (3 g/kg) or water via gastric gavage at 07.30 h. At 09.00 h the ALC and control groups were subdivided where half received either saline or IGF-1 (200 ng) into the third ventricle. A second dose of ALC (1.5, 2 and 3 g/kg) or water was administered at 11.30 h. These regimens produced moderate blood alcohol concentrations of 77, 89 and 117 mg/dl, respectively, over the time course of the experiment. Rats were sacrificed 6 h after the IGF-1 injection and tissues containing the anteroventral periventricular (AVPV) and arcuate (ARC) nuclei were collected. IGF-1 stimulated (P<0.01) KiSS-1 gene expression in the AVPV nucleus at 6 h, but did not affect expression of the kisspeptin receptor, GPR54. While ALC did not alter basal expression of either gene, its dose dependently blocked IGF-1-induced KiSS-1 gene expression in the AVPV nucleus. No changes were observed in the ARC nucleus. Assessment of IGF-1 signaling indicated that the acute administration of IGF-1, ALC, or both did not alter the basal expression of IGF-1 receptor protein. However, IGF-1 stimulated (P<0.05) phosphorylated Akt protein over basal levels, an action blocked by ALC. Our results indicate that the IGF-1 induction of KiSS-1 gene expression is mediated by Akt activation, and that ALC alters this important prepubertal action of IGF-1.

Abstract
OBJECTIVE To assess the rates, timing and causes of neonatal deaths and the burden of stillbirths in rural Uttar Pradesh, India. We discuss the implications of our findings for neonatal interventions. METHODS We used verbal autopsy interviews to investigate 1048 neonatal deaths and stillbirths. FINDINGS There were 430 stillbirths reported, comprising 41% of all deaths in the sample. Of the 618 live births, 32% deaths were on the day of birth, 50% occurred during the first 3 days of life and 71% were during the first week. The primary causes of death on the first day of life (i.e. day 0) were birth asphyxia or injury (31%) and preterm birth (26%). During days 1-6, the most frequent causes of death were preterm birth (30%) and sepsis or pneumonia (25%). Half of all deaths caused by sepsis or pneumonia occurred during the first week of life. The proportion of deaths attributed to sepsis or pneumonia increased to 45% and 36% during days 7-13 and 14-27, respectively. CONCLUSION Stillbirths and deaths on the day of birth represent a large proportion of perinatal and neonatal deaths, highlighting an urgent need to improve coverage with skilled birth attendants and to ensure access to emergency obstetric care. Health interventions to improve essential neonatal care and care-seeking behavior are also needed, particularly for preterm neonates in the early postnatal period.

Abstract
A series of 5-[(N-substituted benzylidenylimino)amino]-2-oxo/thiobarbituric acids (3a-3h) have been synthesized by the condensation of 5-hydrazino-2-oxo/thiobarbituric acids (2a-2b) with various aromatic aldehydes. Cycloaddition of thioglycolic acid to 3a-3h, yielded 5-[(2'-substituted phenyl-4'-oxothiazolidin-3'-yl)amino]-2-oxo/thiobarbituric acids (4a-4h). All these compounds were screened, in vivo, for their anticonvulsant activity and acute toxicity studies. Compounds 4f and 4g were found to be most potent compounds of this series and were compared with the reference drugs, phenytoin sodium, lamotrigine and sodium valproate. The structures of these compounds have been established by IR, 1H NMR and mass spectroscopic data.

Abstract
Dengue, an important human arboviral infection, is endemic in many parts of India. Outbreaks are now reported quite frequently from different parts of the country. We report here findings of serological investigation of serum samples received during a recent outbreak of dengue infection in Delhi from September to November 2003. Acute phase serum samples from suspected cases of dengue infection (including dengue fever, dengue haemorrhagic fever and dengue shock syndrome) of duration 5 days, were tested for dengue specific IgM antibodies by enzyme linked immuno sorbant assay (ELISA). Of the 874 serum samples tested, 456 (52.3% ) were positive for dengue specific IgM antibodies. The maximum number of positive cases was reported in October, peaking in second and third week. Patients in the age group of 21-30 yr accounted for 34.2 per cent of positive cases. This outbreak was less severe as compared to the previous 1996 outbreak and showed a shift towards an older age group.

Abstract
The methanolic, chloroform and ether extracts of Euphorbia tirucalli latex and stem bark were evaluated for larvicidal activity against laboratory-reared larvae of Culex quinquefasciatus (Diptera: Culicidae), vector of the brancroftian filariasis and worst urban nuisance mosquito. The latex extracts contain more potent larvicidal components (177.14 mg/L-326.37 mg/L) than the stem bark extracts (237.663 mg/L-513.39 mg/L). The order of toxicity (LC50) for the latex extracts was Methanol extract (177.14 mg/L) > Chloroform (200.76 mg/L) > Ether (326.37 mg/L) while the rank of order of toxicity (LC50) of stem bark extracts was Ether (237.66 mg/L) > Chloroform (343.515 mg/L) > Methanol (513.387 mg/L), Higher doses (LC90 24 h of mosquito larvae) of each extract did not cause any mortality among fishes after 24 h. The study gave a weight into the possibility of formulating suitable preparation from the latex and stem bark extracts of the plant for use in mosquito control programme.

Abstract
A series of 3-[[5-(alkylbenzylideneamino)-1,3,4-thiadiazol-2-yl]methylamino-2]-methyl-6-monosubstitutedquinazolin-4(3H)-one (4a-4l) have been synthesized via condensation of 3-[(5-amino-1,3,4-thiadiazol-2-yl)methylamino]-2-methyl-6-monosubstitutedquinazolin-4(3H)-one (3a-3b) with various aromatic aldehydes. Cycloaddition of thioglycolic acid with 4a-4l yielded 3-([4-[2-(alkylphenyl)-4-oxo-1,3-thiazolidin-3-yl]-1,3,4-thiadiazol-2-yl]methylamino)-2-methyl-6-monosubstitutedquinazolin-4(3H)-one (5a-5l). The compounds were screened for their anticonvulsant activity and were compared with the standard drugs, phenytoin sodium, lamotrigine and sodium valproate. Out of the 30 compounds the most active compound was 3-([4-[2-(m-methoxy-p-hydroxyphenyl)-4-oxo-1,3-thiazolidin-3-yl]-1,3,4-thiadiazol-2-yl]methylamino)-2-methyl-6-bromo-quinazolin-4(3H)-one (5l).

Abstract
Analgesic, antipyretic and anti-inflammatory activities of newly synthesized spirobarbitunylphenothiazines viz 10-[7, 11-Di(4-4' dimethoxphenyl)-3-oxo-9-methylaminoimino-2, 4-diazaspiro [5.5] undecane 1, 5 dione] acetylphenothiazine (test drug A) and 10-[7, 11-Di (N.N-dimethylaminophenyl)-3-oxo-9-methylaminoimino-2, 4-diazaspiro [5, 5] undecane-1, 5 dione] acetylphenothiazine (test drug B) have been screened in Swiss mice and Wistar rats. The peripheral analgesic activity of test drugs A and B was investigated by acetic acid induced writhing test in Swiss mice while the central analgesic action was assessed by hot-wire (tail flick test) of the analgesiometer and tail-clip test in Wistar rats. Antipyretic activity was assessed on Brewer's yeast induced pyrexic model while antiinflammatory activity was seen on carrageenan induced hind paw oedema. Analgesic activity was found to be only of peripheral type as there was reduction of 66% in writhing responses by test drugs A and B in dose of 80 mg/kg in mice. No change in the tail flick responses was observed on analgesiometer or by tail clip by both the test drugs. Reduction of 1.5 to 2.0 degrees C in rectal temperature was observed in pyretic rats by test drugs A and B in dose of 80 mg/kg. 80% reduction in paw volume was noted in 80 mg/kg dose of both the test drugs which was comparable to the anti-inflammatory activity of 300 mg/kg, p.o. of phenylbutazone.

Abstract
During the past decade intense investigation has focused on cellular aging with the expectation of discovering factors that regulate the replication complex and contribute to the onset and progression of cellular aging. The most striking feature of cellular aging is the failure of sensing diploid cells to enter or complete S phase of the cell cycle. The G1/S phase transition is an initial critical step in the regulation of proliferation in eukaryotic cells, and significant advances have been made toward understanding the basic mechanisms of aging by identifying components of the macromolecular assemblies participating in the G1/S transition. These studies have identified multiple DNA polymerases and their accessory factors, and have provided important strategies for investigating the molecular events that contribute to aging processes. DNA replication, repair and recombination in eukaryotic cells require the action of a variety of DNA polymerases, at least six of which are known, alpha, beta, gamma, delta, epsilon, and zeta. Among them the highly conserved DNA polymerase alpha-primase (pol alpha-primase) is the only enzyme capable of initiating DNA replication at chromosomal origin sites and at sites of initiation of discontinuous synthesis of Okazaki fragments on the lagging side of the replication fork. Numerous protein factors that play strategic roles in DNA replication have been identified and the understanding of their regulation has been an important step for identifying the elements that are involved in, and possibly necessary for, governing cellular senescence and aging. In this review we summarize the current information regarding DNA pol alpha modulation during aging. We focus in particular on the coordinated actions of DNA pol alpha in the presence of other cellular proteins involved in the replication complex in the hope that understanding pol alpha interactions with components of the replication complex may provide insight into the mechanisms by which aging and age-related diseases occur.
