Abstract
Background NVX-CoV2373, a Covid-19 vaccine was developed in the USA with ∼90% efficacy. The same vaccine is manufactured in India after technology transfer (called as SII-NVX-CoV2373), was evaluated in this phase 2/3 immuno-bridging study. Methods This was an observer-blind, randomised, phase 2/3 study in 1600 adults. In phase 2, 200 participants were randomized 3:1 to SII-NVX-CoV2373 or placebo. In phase 3, 1400 participants were randomized 3:1 to SII-NVX-CoV2373 or NVX-CoV2373 (940 safety cohort and 460 immunogenicity cohort). Two doses of study products (SII-NVX-CoV2373, NVX-CoV2373 or placebo) were given 3 weeks apart. Primary objectives were to demonstrate non-inferiority of SII-NVX-CoV2373 to NVX-CoV2373 in terms of geometric mean ELISA units (GMEU) ratio of anti-S IgG antibodies 14 days after the second dose (day 36) and to determine the incidence of causally related serious adverse events (SAEs) through 180 days after the first dose. Anti-S IgG response was assessed using an Enzyme-Linked Immunosorbent Assay (ELISA) and neutralizing antibodies (nAb) were assessed by a microneutralization assay using wild type SARS CoV-2 in participants from the immunogenicity cohort at baseline, day 22, day 36 and day 180. Cell mediated immune (CMI) response was assessed in a subset of 28 participants from immunogenicity cohort by ELISpot assay at baseline, day 36 and day 180. The total follow-up was for 6 months. Trial registration: CTRI/2021/02/031554. Findings Total 1596 participants (200 in Phase 2 and 1396 in Phase 3) received the first dose. SII-NVX-CoV2373 was found non-inferior to NVX-CoV2373 (anti-S IgG antibodies GMEU ratio 0.91; 95% CI: 0.79, 1.06). At day 36, there was more than 58-fold rise in anti-S IgG and nAb titers compared to baseline in both the groups. On day 180 visit, these antibody titers declined to levels slightly lower than those after the first dose (13-22 fold-rise above baseline). Incidence of unsolicited and solicited AEs was similar between the SII-NVX-CoV2373 and NVX-CoV2373 groups. No adverse event of special interest (AESI) was reported. No causally related SAE was reported. Interpretation SII-NVX-CoV2373 induced a non-inferior immune response compared to NVX-CoV2373 and has acceptable safety profile.

Abstract
BACKGROUND: TB is commonly categorised as pulmonary (PTB) or extrapulmonary TB (EPTB). Knowledge of TB disease patterns (PTB and/or EPTB) and determining risk factors remains limited.METHODS: This was a prospective cohort study using point-of-care ultrasound (POCUS) in Indian patients with presumed TB. Clinical and imaging data were used to develop refined case definitions for PTB, concurrent PTB and EPTB (PTB + EPTB) and EPTB without PTB (EPTB). These groups were analysed by HIV (HIV+/-) and diabetes mellitus (DM+/-) status.RESULTS: Of 172 HIV-/DM- patients with TB, 48% had PTB, 23% PTB + EPTB and 29% had EPTB, totalling 52% with any EPTB (PTB + EPTB or EPTB). In HIV+/DM- patients with TB (n = 35), 6% had PTB, 40% had PTB + EPTB and 54% had EPTB, accounting for 94% with EPTB. In HIV-/DM+ patients with TB (n = 61), 61% had PTB, 28% had PTB + EPTB and 11% had EPTB, representing 39% with EPTB.CONCLUSION: Refined case definitions revealed high proportions of EPTB even without HIV or DM. HIV further altered the TB disease pattern towards EPTB and DM towards PTB. Therefore, the dichotomy between PTB or EPTB does not represent the actual spectrum of TB disease. EPTB should receive higher priority in research and clinical practice.

Abstract
Dengue Tetravalent Vaccine, Live-attenuated Recombinant of Panacea Biotec is a lyophilized vaccine based on novel formulation. Dengue Tetravalent Vaccine targets protection against dengue disease caused by all four dengue virus serotypes. Dengue Tetravalent Vaccine Phase I/II clinical trial is the first study conducted in an Indian population and proved to be safe and immunogenic.
Background Dengue fever is the most prevalent mosquito-borne viral disease in the world, with 390 million dengue infections occurring every year. There is an unmet medical need to develop a safe, effective and affordable dengue vaccine against all four Dengue serotype viruses-DENV1, DENV-2, DENV-3 and DENV-4. Panacea Biotec Ltd (PBL) has developed a cell culture-derived, live-attenuated, lyophilized Tetravalent Dengue Vaccine (TDV). Here, in phase I/II study we assessed the safety and immunogenicity of single dose ‘Dengue Tetravalent Vaccine’ in healthy Indian adults. Methods In the study, 100 healthy adult volunteers aged 18–60 years were enrolled. The participants were allocated to TDV and placebo groups in 3:1 ratio, i.e. 75 participants to TDV group and 25 participants to the placebo group. Enrolled participants were administered a single dose of 0.5 ml of the test vaccine / placebo by subcutaneous route. Primary outcome for safety included all solicited AEs up to 21 days, unsolicited AEs up to 28 days and all AEs/serious adverse events (SAEs) till day 90 post-vaccination. For immunogenicity assessment the primary outcome was seroconversion & seropositivity rate by PRNT50 to all four serotype till 90 days. Results Overall, 100 subjects were vaccinated out of which 8 subjects (5 subjects in vaccine group and 3 subjects in placebo group) dropped out from the study. The most commonly reported solicited local AE was pain and most common solicited systemic AE was headache and fever. No SAE was reported during the study. There was no statistically significant difference between TDV and placebo groups in terms of AEs. Of the 92 subjects who completed all scheduled visits in the study, 59 (81.9%) achieved seroconversion for DENV-1, 56 (77.8%) for DENV-2; 59 (81.9%) for DENV-3 and 57 (79.2%) for DENV-4 in TDV group. The seroconversion rate in the TDV group was statistically significant (p < 0.001) compared to placebo. Clinical trial registration: CTRI/2017/02/007923.

Abstract
UNLABELLED Obesity is a leading preventable cause of death and a growing health problem worldwide with increasing rate in both adults and children. Obesity is an important factor causing accelerated aging and various metabolic syndromes. Leptin role as proinflammatory adipokine in obesity is well established. Telomere length acts as a biological clock and a marker for cellular senescence. This study is aimed to quantify leucocyte telomere length & its association with biochemical and anthropometric surrogates of obesity. MATERIAL This cross-sectional study was conducted for a duration of 1yr on patients admitted in the wards or attending OPD, fulfilling the inclusion criteria. After a written informed consent and a thorough history, patient's anthropometric measurements were taken following all guidelines. Based on the values obtained the participants were divided into categories based on age and BMI. Blood samples are collected for the assessment of Leucocyte Telomere length through qPCR technique, Leptin through ELIZA method and HBA1c through HPLC method. OBSERVATION In our present study, a total of 90 patients were included. These patients are equally divided in age groups of 25-39yrs, 40-54yrs and >=55yrs of age. The mean age of the patients was 48.84±16.84yrs. The patients were further categorized equally in each age group into normal, overweight and obese. The mean BMI of the study subjects was 24.20±3.32 kg/m2. Age is found to have a negative correlation with telomere length (r=-0.205). A significant negative correlation of BMI with telomere length is observed (r=-0.20, p<0.05). No significant correlation between leptin with telomere length (r=0.092, p=0.386) or other anthropometric variables is observed. Waist circumference has a positive correlation with waist/hip ratio (r=0.281) (p=0.007), BMI (r=0.640), weight (r=0.677) and neck circumference(r=0.687). Whereas Telomere length has a negative correlation with waist circumference (r= -0.171), neck circumference (r=--0.2266) (p=0.0318) and positive correlation with waist/hip ratio (r=0.043). In our study a negative correlation was observed between waist/ height ratio and telomere length. Waist hip ratio had a positive correlation with BMI (r= 0.138) and telomere length (r=0.232). CONCLUSION Telomere length showed a negative correlation with all anthropometric measures except WHR which showed a positive correlation. Leptin did not show any association with telomere length or anthropometric measures in our study. Our study shows that WHR is a better marker of central obesity than BMI. The notion of metabolically healthy obese also holds true in our study results.

Abstract
Evidence show that shortened telomere length (TL) and low Vitamin D levels can increase the risk of type 2 diabetes mellitus (T2DM) and its associated complications. T2DM has been considered as an age-related disease, it may be associated with TL. The study aimed to evaluate the association of TL and Vitamin D levels with complications of T2DM and the impact of Vitamin D on TL in patients with T2DM. This 1-year cross-sectional study was conducted at a tertiary care hospital on 90 patients. Height, weight, body mass index, waist-hip ratio was calculated. Fasting blood sugars, postprandial blood sugar, and glycated hemoglobin (HbA1c) were analyzed. Absolute TL was obtained from quantitative real-time polymerase chain reaction (qPCR). Vitamin D estimation was done by chemiluminescent immunoassay. Descriptive analysis of the data was done using R i386 3.6.3. The study found a positive correlation between TL and Vitamin D levels (r = 0.64; P < 0.0001). The interaction with high HbA1c levels and lower levels of Vitamin D led to the shortening of TL (P = 0.0001). The median of TL and mean of Vitamin D levels were significantly less in the diabetic group (P < 0.0001). Vitamin D levels positively affected the TL and its levels had an inverse relation with the HbA1c levels. This association had a significant effect on the shortening of TL. Vitamin D also had a significant association with other diabetic complications that instigated the shortening of TL. Therefore, assessing the role of Vitamin D levels on the shortening of TL can prove to be crucial biomarkers in managing optimal glycemic levels in T2DM patients.

Abstract
Background Stroke volume variation (SVV) is a dynamic indicator of preload, which is a determinant of cardiac output. Aims: Aim of this study was to evaluate the relationship between changes in SVV and cardiac index (CI) in patients with normal left ventricular function undergoing major open abdominal surgery. Patients and Methods Patients undergoing major open abdominal surgery were monitored continuously with FloTrac® to measure SVV and CI along with standard monitoring. Both SVV and CI were noted at baseline and every 10 min thereafter till the end of surgery and were observed for concurrence between the measurements. Results 1800 pairs of measurement of SVV and CI were obtained from 60 patients. Mean SVV and CI (of all patients) measured at different time points of measurement showed that as SVV increased with time, the CI dropped correspondingly. When individual readings of CI and SVV were plotted against each other, the scatter was found to be wide, reiterating the lack of agreement between the two parameters (R2 = 0.035). SVV >13% suggesting hypovolemia was found at 207 time points. Of these, 175 had a CI >2.5 L/min/m2 and only 32 patients had a CI <2.5 L/min/m2. Conclusion SVV, a dynamic index of fluid responsiveness can be used to monitor patients expected to have large fluid shifts during major abdominal surgery. It is very specific and has a high negative predictive value. When SVV increases, CI is usually maintained. Since many factors affect SVV and CI, any increase in SVV >13%, must be correlated with other parameters before administration of the fluid challenge.

Abstract
INTRODUCTION Centhaquine (Lyfaquin®) showed significant efficacy as a resuscitative agent in animal models of haemorrhagic shock. Its safety and tolerability were confirmed in healthy human volunteers. In this study, our primary objective was to determine the safety, and the secondary objective was to assess the efficacy of centhaquine in patients with hypovolemic shock. METHODS A prospective, multicentre, randomized phase II study was conducted in male and female patients aged 18-70 years with hypovolemic shock having systolic BP ≤ 90 mmHg. Patients were randomized in a 1:1 ratio to either the control or centhaquine group. The control group received 100 ml of normal saline infusion over 1 h, while the centhaquine group received 0.01 mg/kg of centhaquine in 100 ml normal saline infusion over 1 h. Every patient received standard of care (SOC) and was followed for 28 days. RESULTS Fifty patients were included, and 45 completed the trial: 22 in the control group and 23 in the centhaquine group. The demographics of patients in both groups were comparable. No adverse event related to centhaquine was recorded in the 28-day observation period. The baseline, Injury Scoring System score, haemoglobin, and haematocrit were similar in both groups. However, 91% of the patients in the centhaquine group needed major surgery, whereas only 68% in the control group (p = 0.0526). Twenty-eight-day all-cause mortality was 0/23 in the centhaquine group and 2/22 in the control group. The percent time in ICU and ventilator support was less in the centhaquine group than in the control group. The total amount of vasopressors needed in the first 48 h of resuscitation was lower in the centhaquine group than in the control group (3.12 ± 2.18 vs. 9.39 ± 4.28 mg). An increase in systolic and diastolic BP from baseline through 48 h was more marked in the centhaquine group than in the control group. Compared with the control group, blood lactate level was lower by 1.75 ± 1.07 mmol/l in the centhaquine group on day 3 of resuscitation. Improvements in base deficit, multiple organ dysfunction syndrome (MODS) score and adult respiratory distress syndrome (ARDS) were greater in the centhaquine group than in the control group. CONCLUSION When added to SOC, centhaquine is a well-tolerated and effective resuscitative agent. It improves the clinical outcome of patients with hypovolemic shock.

Abstract
Telomere length is regarded as a potential biomarker of biological ageing and is associated with various age-related diseases, such as ischemic heart disease (IHD), myocardial infarction, peripheral vascular disease, and cancer. As there is a paucity of study that deals with this influence, this study aimed to assess how the cardiovascular risk factors influence the risk of IHD by performing mediation analysis. A total of 407 males were included in the study. IHD was diagnosed through echocardiography and coronary angiography by determining the number of coronary vessels involved. Demographic data, clinical history, and laboratory investigations such as random blood sugar (RBS), fasting lipid profile, serum creatinine, and serum urea levels of all the subjects were measured and recorded. Serum uric acid and blood urea nitrogen (BUN) levels were significantly higher in IHD subjects compared to non-IHD subjects (P < 0.05). Body mass index (BMI), glycosylated hemoglobin (HbA1c), RBS, serum uric acid, serum creatinine, BUN, total cholesterol, triglycerides, and telomere length significantly differed between subjects with and without IHD (P < 0.05). Further, telomere length (P < 0.001), BMI (P < 0.001), and total cholesterol level (P < 0.001) were risk factors that significantly affected the incidence of IHD, as proved by logistic regression. It indicates that shorter telomeres contribute to increased risk of IHD, influenced by BMI, HbA1c, BUN, total cholesterol levels, and RBS (P < 0.001). The study established a link between telomere shortening, conventional risk factors, and IHD; moreover, the study takes care in the role of mediation analysis which is a novel idea as little is done in this area of biostatistics with telomere length. Overall, this further establishes that telomeres length might serve as the promising biomarkers in predicting the risk of IHD.

Abstract
OBJECTIVE To describe differences in outcomes between pregnant women with and without coronavirus dsease 2019 (COVID-19). DESIGN Prospective cohort study of pregnant women consecutively admitted for delivery, and universally tested via nasopharyngeal (NP) swab for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using reverse transcription-polymerase chain reaction. All infants of mothers with COVID-19 underwent SARS-CoV-2 testing. SETTING Three New York City hospitals. POPULATION Pregnant women >20 weeks of gestation admitted for delivery. METHODS Data were stratified by SARS-CoV-2 result and symptomatic status, and were summarised using parametric and nonparametric tests. MAIN OUTCOME MEASURES Prevalence and outcomes of maternal COVID-19, obstetric outcomes, neonatal SARS-CoV-2, placental pathology. RESULTS Of 675 women admitted for delivery, 10.4% were positive for SARS-CoV-2, of whom 78.6% were asymptomatic. We observed differences in sociodemographics and comorbidities among women with symptomatic COVID-10 versus asymptomatic COVID-19 versus no COVID-19. Caesarean delivery rates were 46.7% in symptomatic COVID-19, 45.5% in asymptomatic COVID-19 and 30.9% in women without COVID-19 (P = 0.044). Postpartum complications (fever, hypoxia, readmission) occurred in 12.9% of women with COVID-19 versus 4.5% of women without COVID-19 (P < 0.001). No woman required mechanical ventilation, and no maternal deaths occurred. Among 71 infants tested, none were positive for SARS-CoV-2. Placental pathology demonstrated increased frequency of fetal vascular malperfusion, indicative of thrombi in fetal vessels, in women with COVID-19 versus women without COVID-19 (48.3% versus 11.3%, P < 0.001). CONCLUSION Among pregnant women with COVID-19 at delivery, we observed increased caesarean delivery rates and increased frequency of maternal complications in the postpartum period. Additionally, intraplacental thrombi may have maternal and fetal implications for COVID-19 remote from delivery. TWEETABLE ABSTRACT COVID-19 at delivery: more caesarean deliveries, postpartum complications and intraplacental thrombi.

Abstract
ZnO nanoparticles (NPs) possess a wide range of biological functions in pharmaceutical and cosmetic applications due to their excellent antimicrobial, optical and UV protective properties. This study first reports the toxicological assessment of ZnO NPs green synthesized from Jatropha curcas shells for multifunctional biomedical applications. The hot water extract of J.curcas shells is utilized as a chelating agent for the reduction of zinc acetate and then, the prepared ZnO NPs are broadly characterized using X-ray spectroscopic and electron microscopic observations. The prepared ZnO NPs acquire high purity (100%) wurtzite crystal with hexagonal structure with the average particle size of 53 nm. In vitro and in vivo toxicity evaluation against human tumor cell lines and zebrafish embryos have ascertained the purpose of ZnO NPs in clinical research. Toxic effects of ZnO NPs were observed by a dose-dependent reduction of bacterial growth at ≥1 μg ml-1, by teratogenicity and genotoxicity in zebrafish embryos (from 3 to 90 μg ml-1) and by a significant nanoparticle uptake (0.5 ng μl-1) by a fish serum. In contrast, ZnO NPs fail to reduce the proliferation of human bladder tumor cells (UC6) and cell viability of A549 cells in vitro up to 500 μg ml-1. All these observations limit the unobstructed application of ZnO NPs at higher concentrations. Thus, abundantly used metal oxide nanoparticles like ZnO NPs examined in our present study in different animal models under in vitro and in vivo conditions will be the significant screening strategy to determine the nanotoxicity.

Abstract
Objective The study aimed to explore the relationship of the telomere length with type 2 diabetes mellitus (DM) among patients with ischemic heart disease (IHD). Method This 2-year cross-sectional study included 130 male patients diagnosed with IHD through echocardiography and coronary angiography, wherein consecutive IHD patients with type 2 DM (65) and without type 2 DM (65) were selected. Baseline characteristics including age, gender, body mass index, and blood pressure were recorded. Laboratory investigations such as random blood sugar (RBS), fasting lipid profile, serum creatinine, and serum urea levels were measured. Quantitative real-time polymerase chain reaction was used for the measurement of the telomere length. The logistic regression analysis was used to predict the relationship of the telomere length with age and type 2 DM among patients with IHD. Results All the patients in the study were men, and most of them (diabetics = 22; nondiabetics = 20) were aged between 56 and 65 years. Age (p = 0.003), telomere length (p < 0.001), RBS (p < 0.001), serum creatinine (p < 0013), and serum urea (p < 0.04) were significantly higher in the diabetic subset than in the nondiabetic subset. No significant relationship was observed between age and the telomere length (p = 0.813); however, the mean telomere length was significantly high among the patients with type 2 DM than those without type 2 DM (p = 0.005). The logistic regression analysis showed that the telomere shortening (p = 0.00019) and RBS (p < 0.0001) were the significant risk factors for type 2 DM in patients with IHD. Conclusion The telomere shortening was significantly correlated with type 2 DM among the patients with IHD. However, multicentric studies with larger samples are required to validate the current observation.

Abstract
In the present investigation, the thermostability of a live attenuated buffalopox vaccine prepared with an indigenous baffalopox virus isolate (BPXV Vij/96) and freeze-dried under conventional lyophilizing conditions is described. Three different stabilizer combinations like LS (lactalbumin hydralysate + sucrose), LHT (lactalbumin hydralysate + Trehalose dihydrate) and TAA (Trehalose dihydrate + l- Alanine + l-Histidine) were used to prepare the vaccine. The study indicated that the LS stabilizer was found to be the stabilizer of choice followed by LHT and TAA for buffalopox vaccine at all temperatures studied. The presence of stabilizers has beneficial influence in preserving the keeping quality of the vaccine. Further, among the diluents used to reconstitute the freeze-dried buffalopox vaccine, double distilled water, 0.85% normal saline solution and phosphate buffer saline were the choice of diluents in that order. However, 1M MgSO4 did not perform well at higher temperatures. Investigation suggests for using LS as a stabilizer for freeze-drying and any of the three diluents except 1MgSO4 for reconstitution of buffalopox vaccine.

Abstract
In this investigation, ultrasonication process was used for the synthesis of magnesium doped nano-hydroxyapatite (MH) (0, 1, 2, and 3 mol% of Mg concentration) particles with controlled size and surface morphology. The size of the prepared MH particles was in the range of 20-100 nm with narrow distribution. Increase in the concentration of Mg reduced the particle size distribution from 60 to 40 nm. On incorporation of Mg in HAp lattice, an increase of 20-66 nm in specific surface area was observed in microporous HAp particles. XRF and XRD patterns reveal that the particles possess stoichiometric composition with reduced crystallinity with respect to the Mg concentration. Surface morphology of MH/chitosan (CTS) coated implant was found to be uniform without any defects. The corrosion rate of the implant decreased with increase in Mg concentration. The in vitro formation of bonelike apatite layer on the surface of the MH/CTS coated implant was observed from simulated body fluid studies. The antimicrobial activity of the MH/CTS composites against gram-positive and gram-negative bacterial strains indicated that increasing Mg concentration enhanced antimicrobial properties. Nanoindentation analysis of apatite coated implant surface reveals that the mechanical property depends on the concentration of magnesium in HAp. From the cytotoxicity analysis against NIH 3T3 fibroblast, it was observed that the Mg incorporated HAp/CTS composite was less toxic than the MHO/CTS composite. From this result, it was concluded that the MH/CTS nanocomposites coated implant is the excellent material for implants.

Abstract
BACKGROUND The incidence of aplastic anaemia (AA) is higher in Asia than in the West. The precise incidence of AA in India is not known due to lack of epidemiological study. 20-40% of pancytopenic patients in referral centres are of aplastic anaemia. PATIENTS AND METHODS This was an analysis of 1501 patients diagnosed with aplastic anaemia over a period of seven and half years (January 2007- June 2014) attending the Aplastic clinic of department of haematology of All India Institute of Medical Sciences, New Delhi. The details regarding medical history, physical examination, complete blood count, bone marrow aspirate and biopsy, treatment received, were retrieved. Inherited bone marrow failure was screened in patients below 35 years. Treatment response was analysed for various treatment modalities. RESULTS 1501 patients of AA from 20 different states of India were analysed. The bulk of patients were from Uttar Pradesh (28.7%), Bihar (23.6%), Delhi/NCR (20%) and Haryana (7%).The average number of new aplastic anaemia patients enrolled per year 214 (range: 101 -263). The median age at presentation was 25 years (range 2-83),with M;F - 2.3:1. Severity of AA revealed: severe (SAA): 75%, very severe (VSAA): 15%, non-severe (NSAA): 10%. Inherited bone marrow failure syndromes constituted 5% (75 patients) of all aplastic anaemia patients. The most common clinical presentations were pallor (97%), bleeding manifestations (69.6%) and fever (54%). The haematological parameters showed: median level of haemoglobin level: 5.9 gm/dL, WBC: 2700/mm3, ANC: 380/mm3, platelet: 1 0000/mm3. PNH clone was present in 13.5% of patients. 107 patients (7%) were lost to follow up or expired before any treatment was initiated. Only 69 patients (4.5%) received treatment with HLA-matched sibling stem cell transplantation and another 232 (15.5%) patients received ATG plus cyclosporine as immunosuppressive therapy. Seven hundred thirteenpatients (47.5%) received cyclosporine. The overall response to various treatment modalities was: HLA matched sibling haematopoietic stem cell transplant: 75.3%, Anti-thymocyte globulin plus cyclosporine: 58.7%, cyclosporine plus androgen: 45.6%, cyclosporine alone: 32.2%. CONCLUSION Management of AA is a real challenge in developing countries.This is one of the largest case series from a single centre from India. It is our endeavour to reduce the detrimental outcome by increasing awareness among patients and referring physicians to reduce the delay between diagnosis and treatment.

Abstract
New colorimetric chemosensor, N'-[(E)-3-Bromo-5-Chloro-2-hydroxybenzidene]-4-hydroxybenzohydrazide, containing OH and NH groups as binding sites have been synthesized and characterized by spectral UV, IR, NMR and ESR. The molecular structure of ligand is determined by X-ray crystallography and it has the monoclinic space group P21/c with cell parameters a=15.1058(6), b=14.3433(6), c=17.5800(8)Å and Z=8. The electronic spectral measurements show that Co(2+), Ni(2+) and Zn(2+) complexes have tetrahedral geometry, while Cu(2+) complex has square planar geometry. Magnetic measurements show that Cu(2+), Co(2+) and Ni(2+) complexes have paramagnetic behavior and Zn(2+) complex has diamagnetic behavior. Anion binding studies carried out using (1)H NMR and UV-visible spectrophotometric titrations revealed that these receptors exhibit selective recognition towards F(-) over other halide anions. The selectivity for F(-) among the halides is attributed mainly to the hydrogen-bond interaction of the receptor with F(-). Receptor (5 × 10(-5)M) shows color change from colorless to yellow in the presence of tetrabutylammonium fluoride (TBAF, 1.5 × 10(-3)M). Moreover, F(-)-induced color changes remain the same even in the presence of large excess of Cl(-), Br(-) and I(-). The binding constant is found to be higher towards F(-) ion and this may be due to presence of OH group, which offers extra binding site. Chromogenic receptor undergoes distinct color changes from colorless to green on gradual addition of Cu(2+) can be used as colorimetric probes for spectrophotometric and visual analysis of Cu(2+) in the presence of other transition metal ions such as Co(2+), Ni(2+) and Zn(2+).

Abstract
In the present study, two sheeppox vaccines made from strains [sheeppox virus-Srinagar (SPPV-Srin) and Ranipet (SPPV-R)] indigenous to India and adapted to Vero cells were compared in terms of their safety, potency, efficacy and antigenic value with the commercial in-use Roumanian Fanar (SPPV-RF) vaccine, a foreign strain adapted in primary lamb testes cells. The safety test indicated that the SPPV (Sri and RF) vaccines were safe while SPPV-R was not completely attenuated and caused excessive adverse reactions at the passage level tested. The immunized animals showed DTH reaction and resisted virulent SPPV challenge, while control animals developed disease. Specific virus could be detected in the controls and animals immunized with lower dilutions of vaccines after challenge but not in any of the sheep immunized with 1 and 100 doses of each vaccine. All vaccines were found potent and the PD(50) was highest for SPPV (Srin and R) followed by RF. The immunized animals were seroconverted following vaccination with sustained antibody responses after challenge. In conclusion, indigenous SPPV-Srin vaccine was found to be as efficacious as SPPV-R and SPPV-RF vaccines. Thus, there is potential benefit in replacing the currently used commercial vaccine SPPV-RF with indigenous SPPV-Srin vaccine for use in India.

Abstract
There are two independent mol-ecules in the asymmetric unit of the title compound, C(13)H(9)BrClN(3)O(2), in which the dihedral angles between the benzene and pyridine rings are 8.23 (9)° and 52.84 (12)°. Both the mol-ecules exist in an E configuration with respect to the C=N double bond. The two mol-ecules in the asymmetric unit are linked via weak C-H⋯O hydrogen bonds. In both the mol-ecules, an intra-molecular O-H⋯N hydrogen bond generate an S(6) graph-set motif. In the crystal, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds generate bifurcated R(1) (2)(7) ring motifs. The crystal packing is further stabilized by weak inter-molecular N-H⋯O, N-H⋯N, C-H⋯O and π-π [centroid-centroid distance 3.615 (2) Å] inter-actions.

Abstract
BACKGROUND This study compared anxiety in two groups of women undergoing elective cesarean delivery to ascertain if their partner's presence during neuraxial anesthesia placement affected patients' overall anxiety levels. METHODS Three hundred fifteen patient-partner dyads were randomized to two groups: group 1 partners were present in the operating room during neuraxial anesthesia placement while group 2 partners remained outside the operating room during placement. Before surgery, all patient-partner dyads completed a survey of demographics, anesthetic experiences and baseline anxiety. Anxiety levels were rated using a visual analogue scale (VAS) and the state portion of the Spielberger State-Trait Anxiety Inventory. RESULTS The mean change in anxiety as measured by VAS among patients whose partners were present in the operating room for neuraxial anesthetic placement decreased from before to after the procedure (-4.5+/-25.8; P=0.03; 95% CI -8.55, -0.45); the mean change in anxiety in patients whose partners were not present did not alter significantly (+1.9 +/- 25.3; P=0.34; 95% CI 6.68, 12.12). Anxiety was increased among partners who were not present (+9.4, P<0.001). CONCLUSION Although patients whose partners were present in the operating room at the time of neuraxial anesthesia placement reported less anxiety over the time of the study than did patients whose partners were not present, these differences were small and are not considered to be clinically important. Increased anxiety among partners who were not present at neuraxial placements warrants further study.
