Abstract
CONTEXT Circulating lactate concentration is an important determinant of exercise tolerance. OBJECTIVE To determine the role of hyperglycemia on lactate metabolism during exercise in type 1 diabetes (T1D). DESIGN Protocol involved compared T1D participants and participants without diabetes (ND) at euglycemia [5.5mM] or hyperglycemia [9.2mM] in random order in T1D and at euglycemia in ND. SETTING Clinical Research Unit, University of Virginia, Charlottesville, VA. PARTICIPANTS 7 T1D and 7 ND. INTERVENTION [1-13C] lactate infusion, exercise at 65% VO2max, euglycemia and hyperglycemia visits. MAIN OUTCOME MEASURE Lactate turnover before, during and after 60 min of exercise at 65% VO2max. RESULTS A two-compartment model with loss only from the peripheral compartment described lactate kinetics. Volume of distribution of the accessible compartment was similar between T1D and ND (p=0.76) and concordant to plasma volume (∼40ml/kg). Circulating lactate concentrations were higher (p<0.001) in T1D participants during exercise at hyperglycemia than euglycemia. Exercise induced lactate appearance did not differ (p=0.13) between hyperglycemia and euglycemia. However, lactate clearance was lower (p=0.03) during hyperglycemia than euglycemia in T1D. There were no differences in any of the above parameters between T1D and ND during euglycemia. CONCLUSIONS Hyperglycemia modulates lactate metabolism during exercise by lowering lactate clearance leading to higher circulating lactate concentrations in T1D. This novel observation implies that exercise during hyperglycemia can lead to higher circulating lactate concentrations thus increasing the likelihood of reaching the lactate threshold sooner in T1D, and has high translational relevance for both providers and recreationally active people with Type 1 diabetes.

Abstract
The Ferrier rearrangement is a powerful tool to prepare 2,3-unsaturated glycopyranosides. We have reinvestigated SnCl4 catalyzed Ferrier rearrangements through direct allylic substitution of the hydroxyl group at the C-3 position of glycals, resulting in the formation of stereoselective 2,3-unsaturated glycosides at 0 °C. The catalytic amount of SnCl4 (0.1 equiv.) was successfully used to promote this transformation on 3,4,6-tri-O-acetyl-D-glucal, 3,4,6-tri-O-acetyl-D-galactal and 3,4-di-O-acetyl-D-arabinal using various nucleophiles viz alcohols, azide and thiols to form a variety of 2,3-unsaturated glycopyranosides (pseudoglycals). This straightforward process is notable for its strong anomeric selectivity, excellent yields and shorter reaction time.

Abstract
Electric double layer (EDL)-mediated transistors with ionic liquid (IL) gating have garnered substantial interest due to their exceptional properties, such as high transconductance and low-voltage operation, positioning them as promising candidates for organic electronics. In this study, we present an in situ measurement of effective gate bias voltage (VGS,eff) in IL-gated organic field-effect transistors (IL-OFETs) using a modified current-voltage measurement configuration. The results reveal a significant deviation between VGS,eff and the applied gate bias (VGS,app), indicating that the EDL at the gate/IL interface screens the applied voltage. It is observed that the screening effect varies depending on the specific cation and anion present in the IL. The evaluation of VGS,eff plays a pivotal role in understanding the intrinsic behavior of IL-OFETs and addresses the challenges associated with accurate performance assessment. Inherently, IL-OFETs demonstrate high transconductance, achieving values of approximately 9 mS while operating at a low threshold voltage of around 0.55 V. Through the acquisition of VGS,eff, we have successfully addressed the limitations impeding the numerical estimation of the trap density of states (trap DOS) in IL-OFETs. Remarkably, our calculations reveal an exceptionally low density of deep traps, which serves as a crucial factor contributing to the near-ideal subthreshold swing (61-68 mV dec-1) observed in IL-OFETs. Further investigations unveil the neutral electrical nature of the IL bulk during OFET operation, confirming the hypothesis that the applied gate bias voltage in electrolyte-gated OFETs drops across the EDLs formed at the interfaces. The impedance spectroscopic (IS) analysis confirms the low contact resistance (≈1 Ω·m) of IL-OFETs calculated using the transition voltage method. The IS analysis also reveals the low-transmissive nature of the IL/organic semiconductor interface. The knowledge gained from this study holds significant implications for realizing high-performance electrolyte-gated OFETs in various applications including digital electronics, energy storage, and sensing. By unraveling the factors influencing the device performance, such as VGS,eff and trap DOS, this research contributes to the advancement of organic electronics and paves the way for future developments in the field.

Abstract
Viral infections are the most important health concern nowadays to mankind, which is unexpectedly increasing the health complications and fatality rate worldwide. The recent viral infection outbreak developed a pressing need for small molecules that can be quickly deployed for the control/treatment of re-emerging or new emerging viral infections. Numerous viruses, including the human immunodeficiency virus (HIV), hepatitis, influenza, SARS-CoV-1, SARS-CoV-2, and others, are still challenging due to emerging resistance to known drugs. Therefore, there is always a need to search for new antiviral small molecules that can combat viral infection with new modes of action. This review highlighted recent progress in developing new antiviral molecules based on natural product-inspired scaffolds. Herein, the structure-activity relationship of the FDA-approved drugs along with the molecular docking studies of selected compounds have been discussed against several target proteins. The findings of new small molecules as neuraminidase inhibitors, other than known drug scaffolds, Anti-HIV and SARS-CoV are incorporated in this review paper.

Abstract
Assessing free fatty acids (FFAs) kinetics and the role of insulin and glucose on FFA lipolysis and disposal may improve our understanding of the pathogenesis of type 2 diabetes (T2D). Some models have been proposed to describe FFA kinetics during an intravenous glucose tolerance test and only one during an oral glucose tolerance test. Here, we propose a model of FFA kinetics during a meal tolerance test and use it to assess possible differences in postprandial lipolysis in individuals with type 2 diabetes (T2D) and individuals with obesity without type 2 diabetes (ND). We studied 18 obese ND and 16 T2D undergoing three meal tolerance tests (MTT) on three occasions (breakfast, lunch, and dinner). We used plasma glucose, insulin, and FFA concentrations collected at breakfast to test a battery of models and selected the best one based on physiological plausibility, ability to fit the data, precision of parameter estimates, and the Akaike parsimony criterion. The best model assumes that the postprandial suppression of FFA lipolysis is proportional to the above basal insulin, while FFA disposal is proportional to FFA concentration. It was used to compare FFA kinetics in ND and T2D along the day. The maximum lipolysis suppression occurred significantly earlier in ND than T2D (39 ± 6 min vs. 102 ± 13 min, 36 ± 4 min vs. 78 ± 11 min, and 38 ± 6 min vs. 84 ± 13 min, P < 0.01, at breakfast, lunch, and dinner, respectively), making lipolysis significantly lower in ND than T2D. This is mainly attributable to the lower insulin concentration in the second group. This novel FFA model allows to assess lipolysis and insulin antilipolytic effect in postprandial conditions.NEW & NOTEWORTHY In this study, we propose a new mathematical model able to quantify postprandial FFA kinetics and adipose tissue insulin sensitivity in both subjects with obesity without type 2 diabetes (ND) and subjects with type 2 diabetes (T2D). Results show that the slower postprandial suppression of lipolysis in T2D contributes to the higher free fatty acid (FFA) concentration that, in turn, may contribute to hyperglycemia.

Abstract
This review highlights the recent synthetic developments of benzothiazole based anti-tubercular compounds and their in vitro and in vivo activity. The inhibitory concentrations of the newly synthesized molecules were compared with the standard reference drugs. The better inhibition potency was found in new benzothiazole derivatives against M. tuberculosis. Synthesis of benzothiazole derivatives was achieved through various synthetic pathways including diazo-coupling, Knoevenagel condensation, Biginelli reaction, molecular hybridization techniques, microwave irradiation, one-pot multicomponent reactions etc. Other than recent synthetic developments, mechanism of resistance of anti-TB drugs is also incorporated in this review. Structure activity relationships of the new benzothiazole derivatives along with the molecular docking studies of selected compounds have been discussed against the target DprE1 in search of a potent inhibitor with enhanced anti-tubercular activity.

Abstract
The influenza virus remains a major health concern for mankind because it tends to mutate frequently and cause high morbidity. Influenza prevention and treatment are greatly aided by the use of antivirals. One such class of antivirals is neuraminidase inhibitors (NAIs), effective against influenza viruses. A neuraminidase on the virus's surface serves a vital function in viral propogation by assisting in the release of viruses from infected host cells. Neuraminidase inhibitors are the backbone in stoping such virus propagation thus helps in the treatment of influenza viruses infections. Two NAI medicines are licensed globally: Oseltamivir (Tamiflu™) and Zanamivir (Relanza™). There are two molecules that have acquired Japanese approval recently: Peramivir and Laninamivir, whereas Laninamivir octanoate is in Phase III clinical trials. The need for novel NAIs is due to frequent mutations in viruses and the rise in resistance against existing medication. The NA inhibitors (NAIs) are designed to have (oxa)cyclohexene scaffolds (a sugar scaffold) to mimic the oxonium transition state in the enzymatic cleavage of sialic acid. This review discusses in details and comprises all such conformationally locked (oxa)cyclohexene scaffolds and their analogues which have been recently designed and synthesized as potential neuraminidase inhibitors, thus as antiviral molecules. The structure-activity relationship of such diverese molecules has also been discussed in this review.

Abstract
Introduction Pregnancy is an altered immunological state and not necessarily an immune-compromised state. These immune changes subject pregnant women to increased susceptibility to infection. During the coronavirus disease 2019 (COVID-19) pandemic, pregnant women were more susceptible to serious illness for reasons other than their immune response. The purpose of this study was to compare the feto-maternal outcome (morbidity and mortality) in relation to pre-existing maternal co-morbidities, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection-related disease severity, and its impact on the mode of delivery and long-term sequelae in pregnant women in the first and second waves of the COVID-19 pandemic. Materials and methods This was a hospital-based comparative study carried out on 101 pregnant patients during the first wave (April 2020 to December 2020) and 22 patients in the second wave (March 2021 to July 2021) of the COVID-19 pandemic, in Rajashri Dashrath Autonomous State Medical College, Ayodhya, India. All pregnant women with COVID-19 in the first and second waves were included. Non-pregnant patients with COVID-19 infection, pregnant patients lost to follow-up, pregnant patients without COVID-19 infection, and patients in the puerperal period were excluded. Results Seventy-three (72.27%) patients in the first wave and 12 (54.54%) in the second wave were asymptomatic. Those with mild disease numbered 20 (25.74%) in the first wave and six (27.27%) in the second wave. Disease severity was more in the second wave, that is four (18.18%) as compared to one (0.99%) in the first wave. Severe anemia was the most common co-morbidity associated with both first (n=4, 3.96%) and second (n=5, 22.72%) waves. Four (6.45%) spontaneous abortions occurred in the first wave as compared to three (20%) in the second wave. Intensive care unit (ICU) admission was more in the second wave (n=4, 26.66%) as compared to the first wave (n=1, 1.61%). Two (13.33%) maternal deaths occurred in the second wave and none in the first wave. Cesarean sections in both the first and second waves were performed for obstetric indications only. No newborns tested positive in the COVID-19 reverse transcription-polymerase chain reaction (RT-PCR) in the first and second waves at the time of birth; however, three (4.83%) tested positive on day five of birth in the first wave. Fever was the most common presentation in newborns; seven (11.26%) in the first wave and three (20%) in the second wave. No neonatal death occurred in the first or second waves. No congenital anomalies were noted in the first or second waves of COVID-19. Conclusion In this study, we found that the maximum number of COVID-19-positive pregnant patients in both the first and second waves of COVID-19 were either asymptomatic or had mild infections. Second-wave infection was more lethal as compared to the first wave in terms of adverse maternal as well as fetal outcomes. No gestational age was an exception to the severity of disease and its adverse feto-maternal outcome. In our study, maternal co-morbidities did not impact the overall outcome. All cesarean sections were performed for indications other than COVID-19 infection. Long-term sequelae associated with COVID-19 were seen in both groups but more so in the second wave. No long-term sequelae like congenital anomalies in the babies were associated with COVID-19 either in the first or second wave.

Abstract
To assess the diurnal patterns of postprandial glucose tolerance and insulin sensitivity, 19 subjects with type 2 diabetes (8 women; 60 ± 11 years; BMI 32 ± 5 kg/m2) and 19 anthropometrically matched subjects with no diabetes (ND; 11 women; 53 ± 12 years; BMI 29 ± 5 kg/m2) were studied during breakfast (B), lunch (L), and dinner (D) with identical mixed meals (75 g carbohydrates) on 3 consecutive days in a randomized Latin square design. Three stable isotopes of glucose were ustilized to estimate meal fluxes, and mathematical models were used in estimating indices of insulin action and β-cell function. Postmeal glucose excursions were higher at D versus B and at D versus L in type 2 diabetes (P < 0.05), while in ND they were higher at D versus B (P = 0.025) and at L versus B (P = 0.04). The insulin area under the curve was highest at B compared with L and D in type 2 diabetes, while no differences were observed in ND. Disposition index (DI) was higher at B than at L (P < 0.01) and at D (P < 0.001) in ND subjects, whereas DI was low with unchanging pattern across B-L-D in individuals with type 2 diabetes. Furthermore, between-meal differences in β-cell responsivity to glucose (F) and insulin sensitivity (SI) were concurrent with changes in the DI within groups. Fasting and postmeal glucose, insulin, and C-peptide concentrations, along with estimates of endogenous glucose production (EGP), Rd, SI, F, hepatic extraction of insulin, insulin secretion rate, extracted insulin, and DI, were altered in type 2 diabetes compared with ND (P < 0.011 for all). The data show a diurnal pattern of postprandial glucose tolerance in overweight otherwise glucose-tolerant ND individuals that differs from overweight individuals with type 2 diabetes. The results not only provide valuable insight into management strategies for better glycemic control in people with type 2 diabetes, but also improved understanding of daytime glucose metabolism in overweight individuals without impaired glucose tolerance or overt diabetes.

Abstract
BACKGROUND The aim of this study was to determine whether anterior scleral thickness (AST) varies significantly between patients with central serous chorioretinopathy (CSCR) versus normal individuals. To validate scleral thickness measurements by ultrasound biomicroscopy (UBM) vis a vis anterior segment optical coherence tomography (ASOCT). METHODS This case-control study analyzed 50 eyes of 50 patients with CSCR (cases) and compared it with that of 50 eyes of 50 age- and gender-matched controls. In cases, AST was measured at 1 mm and 2 mm temporal to the temporal scleral spur by ASOCT and UBM. In controls, AST was measured only by ASOCT. In all participants, posterior choroidal thickness (CT) was measured subfoveally, 1 mm nasal and 1 mm temporal to fovea by enhanced depth imaging optical coherence tomography. RESULTS The mean AST, as measured by ASOCT among cases and controls was 703.86 μm and 667.54 μm, respectively (P = 0.006). The mean AST by ASOCT and UBM in cases were 703.86 μm and 657.42 μm, respectively (P = 0.001). AST measurement by ASOCT and UBM showed a positive and statistically significant correlation (r = 0.431, P = 0.000). The mean CT among cases and controls was 443.56 μm and 373.88 μm, respectively (P = 0.000). We found a weak positive correlation (r = 0.11) in cases and weaker positive correlation in controls, between CT and AST measured by ASOCT. CONCLUSIONS Our findings suggest that AST varies significantly between patients with CSCR versus normal individuals. We found poor agreement of AST when measured by ASOCT and UBM.

Abstract
Background: Anthropometry is widely used for Identification of an individual. Height is one of the most important parameters of anthropometry. It is strongly correlated with the individual’s hand dimensions and if either of the measurements are known, the other can be calculated. Aim and Objective: To know correlation between the hand dimensions and Height of an individual and to apply the regression line of height on hand dimension of the person. Methods and Material: A cross-sectional study was conducted among the medical students. Anthropometric indices were recorded after obtaining written consent and institutional approval using standard equipments. Linear regression and Pearson coefficient were calculated to study the correlation and arrive at the equation to calculate Height from Hand length. Results: Age of the study participants who consented for study (150) ranged between 18-24 years. Mean height was 165.91 cm. Mean right hand length was 17.71 cm and 17.69 cm on left hand. Mean hand width was 7.79 cm on right side and 7.56 cm on left side. A statistically significant positive correlation was observed between height and the hand dimensions. Conclusions: There was a statistically significant positive correlation between hand dimensions and height. Forensic investigation, body identification and triage can be facilitated through calculating Height from hand dimensions when only mutilated body remains are received during disasters.

Abstract
Background - The antiretroviral protease inhibitor drug lopinavir (LPV) is used to treat HIV-1 infection. LPV is known to have limited oral bioavailability, which may be attributed to its poor aqueous solubility, low efficacy and high first-pass metabolism. Self-nanoemulsifying drug delivery systems (SNEDDS) for LPV have been developed and optimised to counter the current issues. Methods- The titration method was used to prepare LPV-loaded SNEDDS (LPV-SNEDDS). Six different pseudo-ternary phase diagrams were constructed to identify the nanoemulsifying region. The developed formulations were chosen in terms of globule size < 100 nm, dispersity ≤ 0.5, dispersibility (Grade A) and % transmittance > 85. Heating-cooling cycle, freeze-thaw cycle, and centrifugation studies were performed to confirm the stability of the developed SNEDDS. Results-The final LPV-SNEDDS (L-14) droplet size was 58.18 ± 0.62 nm, with polydispersity index, zeta potential, and entrapment efficiency (EE%) values of 0.326 ± 0.005, -22.08 ± 1.2 mV, and 98.93 ± 1.18%, respectively. According to high-resolution transmission electron microscopy (HRTEM) analysis, the droplets in the optimised formulation were < 60 nm in size. The selected SNEDDS released nearly 99% of the LPV within 30 min, which was significantly (p < 0.05) higher than the LPV-suspension in methylcellulose (0.5% w/v). It indicates the potential use of SNEDDS to enhance the solubility of LPV, which eventually could help improve the oral bioavailability of LPV. The Caco-2 cellular uptake study showed a significantly (p < 0.05) higher LPV uptake from the SNEEDS (LPV-SNEDDS-L-14) than the free LPV (LPV-suspension). Conclusion- The LPV-SNEDDS could be a potential carrier for LPV oral delivery.

Abstract
Introduction Cervical spinal stenosis is a common disease that results in considerable morbidity and disability. To avoid long-term disability caused by irreversible spinal cord damage, quick diagnosis and treatment are required. To our knowledge, until recently, there has been no report or study evaluating the cervical canal stenosis and associated facet joint arthrosis as the major cause of neck pain, so the current study used computed tomography (CT) scans to determine the prevalence of cervical canal stenosis and facet joint osteoarthrosis in patients who presented with neck pain, including its relationship with age, sex, and cervical spinal levels (C3-C7). Methods The current clinical descriptive cross-sectional study was conducted in the Department of Anatomy and Radiodiagnosis at Santosh Medical College, Ghaziabad, for a period of 24 months among newly diagnosed outpatient department (OPD) cases of neck pain (18 years or older) with suspected cervical canal stenosis and facet joint arthrosis. Clinical history, patient-specific clinical examination, and relevant information were obtained in a structured data collection schedule through interviews during OPD hours. All of the participants underwent a CT scan of the cervical region. The independent factors (age, gender, height, and weight) were used in a multiple linear regression analysis of neck pain grading, Torg ratio (TR), and right and left facet joint degeneration, which were expressed as R-squared (R2) and adjusted R-squared (aR2). Statistical tests were executed at a 5% level of significance; an association was considered significant if the p-value was <0.05. Results A total of 83 subjects were enrolled in this study with equal representation from both sexes, i.e., males (49.4%) and females (50.6%). The transverse vertebral canal (T-VC) diameter was narrowest at the level of C3 (25.00 ± 1.13) and gradually increased at the level of C6 (25.18 ± 1.14) in this study. The mean TR of cervical vertebrae C3-C4 dropped gradually from C3 (0.78 ± 0.05) to C7 (0.76 ± 0.05) in this study. Severe left and right facet joint degeneration were observed in 13.3% and 10.5% of study subjects, respectively. In almost every subject, neck pain was a neurological symptom, so multiple linear regression analysis of neck pain grading was carried out with the independent variables (age, gender, height, and weight) and it was found to be not significant (R2 = 0.0617, aR2 = 0.0136, p = 0.2842). Conclusion The articulations of the posterior arch of the vertebrae are known as facet joints. They are a vital component of the vertebral column's structural stability. The superior and inner articular facets of the vertebrae are joined by these joints, which are encased in a fibrous capsule.

Abstract
AIM To evaluate whether short-term treatment with a selective 11β-Hydroxysteroid dehydrogenase-1 (11β-HSD1) inhibitor, AZD4017, would block hepatic cortisol production and thereby decrease hepatic fat in patients with nonalcoholic fatty liver disease (NAFLD)/nonalcoholic steatohepatitis (NASH), with or without type 2 diabetes (T2D). MATERIALS AND METHODS This was a randomized, double-blind, placebo-controlled, phase 2 study conducted at two sites. Key inclusion criteria were the presence of NAFLD or NASH on magnetic resonance imaging (MRI) or recent biopsy positive for NASH. Enrolled patients were randomly assigned (1:1) to AZD4017 or placebo for 12 weeks. Primary outcomes were between-group differences in mean change from baseline to week 12 in liver fat fraction (LFF) and conversion of 13 C cortisone to 13 C cortisol in the liver. RESULTS A total of 93 patients were randomized; 85 patients completed treatment. The mean (standard deviation [SD]) change in LFF was -0.667 (5.246) and 0.139 (4.323) in the AZD4017 and placebo groups (P = 0.441). For patients with NASH and T2D, the mean (SD) change in LFF was significantly improved in the AZD4017 versus the placebo group (-1.087 [5.374] vs. 1.675 [3.318]; P = 0.033). Conversion of 13 C cortisone to 13 C cortisol was blocked in all patients in the AZD4017 group. There were no significant between-group differences (AZD4017 vs. placebo) in changes in fibrosis, weight, levels of liver enzymes or lipids, or insulin sensitivity. CONCLUSION Although the study did not meet one of the primary outcomes, AZD4017 blocked the conversion of 13 C cortisone to 13 C cortisol in the liver in all patients who received the drug. In patients with NASH and T2D, AZD4017 improved liver steatosis versus placebo.

Abstract
Cefuroxime axetil (CA) is an oral cephalosporin which hydrolyzes rapidly to the active parent compound cefuroxime. CA is known to have incomplete oral bioavailability (30−50%) due to its poor solubility and enzymatic conversion to cefuroxime in the gut lumen. In order to overcome these drawbacks, a lipid-based self-nanoemulsifying drug delivery system (SNEDDS) has been developed and optimized. The SNEDDS formulations were prepared using the aqueous phase titration method. The greatest self-emulsifying area was found in the 2:1 Smix ratio. As a result, different SNEDDS formulations were carefully selected from this phase diagram based on their smaller droplet size < 100 nm, polydispersity index ≤ 0.5, dispersibility (Grade A), and transmittance (%) > 85%. Thermodynamic stability tests were carried out in order to rule out any metastable/unstable SNEDDS formulations. The droplet size, polydispersity index, zeta potential, and entrapment efficiency (% EE) of optimized CA-loaded SNEDDS (C-3) were 18.50 ± 1.83 nm, 0.064 ± 0.008, −22.12 ± 1.20 mV, and 97.62 ± 1.06%, respectively. In vitro release studies revealed that the SNEDDS formulation had increased CA solubility. CA-SNEDDS-C3 increased CA cellular uptake, possibly due to increased CA solubility and the inhibition of enzymatic conversion to cefuroxime. Finally, in terms of the improvement of oral bioavailability, CA-loaded-SNEDDS could be a viable alternative to commercially available CA formulations.

Abstract
Introduction The consequences of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) /Coronavirus disease 2019 (COVID-19) on mothers and neonates are uncertain due to the lack of robust evidence from various available studies. Furthermore, conflicting data exist regarding the vertical transmission of coronavirus. Therefore, a hospital-based study was conducted to evaluate the effect of COVID-19 on maternal and perinatal outcomes of COVID-19 infected pregnant women. Methodology A hospital-based retrospective observational study was conducted between July-December 2020 in Rajarshi Dashrath Autonomous State Medical College, Ayodhya, Uttar Pradesh, a designated level-2 COVID-19 Hospital. A total of 37 confirmed COVID-19 positive pregnant women (mean age 27.5 ± 05 years) of more than 28 weeks of gestation were included in this study to evaluate the effect of COVID-19 on maternal and perinatal outcomes. Maternal symptoms related to COVID-19, comorbidities, intensive care unit (ICU) admissions, intrauterine growth retardation (IUGR), leaking per vagina, mode of delivery, preterm deliveries, and maternal deaths were recorded. Birth weight of newborns, neonatal intensive care unit (NICU) admissions, neonatal illness, neonatal deaths, and COVID-19 testing reports were recorded. Result Out of 37 COVID-19 positive pregnant women, 27 (72.9%) women were asymptomatic, nine (24.4%) women were having mild disease, and one (2.7%) developed severe disease requiring ICU admission. No maternal deaths were observed. Twenty-six (70.3%) women were delivered by caesarean section, 11 (29.7%) women by normal vaginal delivery, four (10.8%) were of leaking per vagina. Among newborns, five (13.5%) were preterm, one (2.7%) newborn require NICU admission, two (5.4%) were tested COVID-19 positive on the 5th day of life but were asymptomatic, and four (10.8%) newborns developed a fever but were COVID-19 negative. One case (2.7%) was of stillbirth. No neonatal deaths were observed. Conclusion The present study did not reveal any direct evidence for vertical transmission of SARS-CoV-2 virus through the placenta and during vaginal delivery, but the possibility of mother-to-child infection cannot be completely ignored. SARS-CoV-2 infection during late pregnancy may have a maternal and neonatal impact. COVID-19 infections in late pregnancy might lead to an increased incidence of caesarean deliveries as observed in the present study. This study reveals that most of the COVID-19 positive pregnant women remained asymptomatic or had mild infections. Hence, efforts to limit exposure to COVID-19 of pregnant women should be strengthened for saving mother and child.

Abstract
Glucocorticoids are potent immunosuppressive and anti-inflammatory drugs used for various systemic and localized conditions. The use of glucocorticoids needs to be weighed against their adverse effect of aggravating hyperglycemia in persons with diabetes mellitus, unmask undiagnosed diabetes mellitus, or precipitate glucocorticoid-induced diabetes mellitus appearance. Hyperglycemia is associated with poor clinical outcomes, including infection, disability after hospital discharge, prolonged hospital stay, and death. Furthermore, clear guidelines for managing glucocorticoid-induced hyperglycemia are lacking. Therefore, this consensus document aims to develop guidance on the management of glucocorticoid-induced hyperglycemia. Twenty expert endocrinologists, in a virtual meeting, discussed the evidence and practical experience of real-life management of glucocorticoid-induced hyperglycemia. The expert group concluded that we should be proactive in terms of diagnosis, management, and post-steroid care. Since every patient has different severity of underlying disease, clinical stratification would help understand patient profiles and determine the treatment course. Patients at home with pre-existing diabetes who are already on oral or injectable therapy can continue the same as long as they are clinically stable and eating adequately. However, depending on the degree of hyperglycemia, modification of doses may be required. Initiating basal bolus with correction regimen is recommended for patients in non-intensive care unit settings. For patients in intensive care unit, variable rate intravenous insulin infusion could be temporarily used, but under supervision of diabetes inpatient team, and patients can be transitioned to subcutaneous insulin once stable baseline assessment and continual evaluation are crucial for day-to-day decisions concerning insulin doses. Glycemic variability should be carefully monitored, and interventions to treat patients should also aim at achieving and maintaining euglycemia. Rational use of glucose-lowering drugs is recommended and treatment regimen should ensure maximum safety for both patient and provider. Glucovigilance is required as the steroids taper during transition, and insulin dosage should be reduced subsequently. Increased clinical and economic burden resulting from corticosteroid-related adverse events highlights the need for effective management. Therefore, these recommendations would help successfully manage GC-induced hyperglycemia and judiciously allocate resources.

Abstract
INTRODUCTION Propionic acid (PA) is a common food preservative generally recognized as safe by the US Food and Drug Administration; however, exogenous PA has effects on glucose metabolism that are not fully understood. Our preclinical studies demonstrated exogenous PA increases glucagon, norepinephrine, and endogenous glucose production (EGP). RESEARCH DESIGN AND METHODS We performed a randomized, placebo-controlled, crossover study in 28 healthy men and women to determine the effect of PA (1500 mg calcium propionate) on these factors. Subjects had two study visits, each preceded by a 1 week, PA-free diet. During each visit, glucose, insulin, glucagon, norepinephrine, epinephrine, and EGP were assessed for 2 hours after oral administration of PA/placebo under resting conditions (protocol 1) and during either a euglycemic (~85-90 mg/dL) or hypoglycemic (~65-70 mg/dL) hyperinsulinemic clamp (protocol 2). RESULTS PA, as compared with placebo, significantly increased: (1) glucagon and norepinephrine during protocol 1; (2) glucagon, norepinephrine, and epinephrine under euglycemic conditions in protocol 2; and (3) norepinephrine, epinephrine, and EGP under hypoglycemic conditions in protocol 2. CONCLUSION Oral consumption of PA leads to inappropriate activation of the insulin counterregulatory hormonal network. This inappropriate stimulation highlights PA as a potential metabolic disruptor.

Abstract
Highly stable symmetric and asymmetric squaraine fluorophores have been synthesized featuring an internal salt bridge between a quaternary ammonium cation and the central oxycyclobutenolate ring of the chromophore. Some of our newly synthesized symmetric and asymmetric compounds display increased molar absorptivity, quantum yield in serum, and thermal/photochemical stability over previously reported squaraine-based dyes. Consequently, both classes show great promise in resurfacing the normal environment-labile squaraine dyes as novel imaging agents and scaffolds for fluorescence sensing. Furthermore, incorporating a covalent attachment point away from the conjugated system allows for biological tagging applications without disturbing the optimum optical characteristics of the newly designed fluorophore.

Abstract
CONTEXT The effect of physiological changes in night-time cortisol and glucagon on endogenous glucose production (EGP) and nocturnal glycemia are unknown. OBJECTIVE To determine the effects of changes in cortisol and glucagon on EGP during the night. DESIGN Two overnight protocols were conducted. In Protocol 1, endogenous cortisol was blocked with metyrapone and hydrocortisone infused either at constant (constant) or increasing (variable) rates to mimic basal or physiological nocturnal cortisol concentrations. In Protocol 2, endogenous glucagon was blocked with somatostatin and exogenous glucagon was infused at either basal or elevated rates to mimic nocturnal glucagon concentrations observed in nondiabetic (ND) and type 2 diabetes (T2D) individuals. EGP was measured using [3-3H] glucose and gluconeogenesis estimated with 2H2O in all studies. SETTING Mayo Clinic Clinical Research Trials Unit, Rochester, MN, US. PARTICIPANTS In Protocol 1, 34 subjects (17 ND and 17 T2D) and in Protocol 2, 39 subjects (21 ND and 18 T2D) were studied. MAIN OUTCOME MEASURES Endogenous glucose production. RESULTS EGP, gluconeogenesis, and glycogenolysis were higher with variable than with constant cortisol at 7 am in T2D subjects. In contrast, nocturnal EGP did not differ in ND subjects between variable and constant cortisol. While elevated glucagon increased EGP, glycogenolysis, and gluconeogenesis in ND, the data in T2D subjects indicated that EGP and gluconeogenesis but not glycogenolysis were higher during the early part of the night. CONCLUSION Nocturnal hyperglucagonemia, but not physiological rise in cortisol, contributes to nocturnal hyperglycemia in T2D due to increased gluconeogenesis.

Abstract
We report an ancient genome from the Indus Valley Civilization (IVC). The individual we sequenced fits as a mixture of people related to ancient Iranians (the largest component) and Southeast Asian hunter-gatherers, a unique profile that matches ancient DNA from 11 genetic outliers from sites in Iran and Turkmenistan in cultural communication with the IVC. These individuals had little if any Steppe pastoralist-derived ancestry, showing that it was not ubiquitous in northwest South Asia during the IVC as it is today. The Iranian-related ancestry in the IVC derives from a lineage leading to early Iranian farmers, herders, and hunter-gatherers before their ancestors separated, contradicting the hypothesis that the shared ancestry between early Iranians and South Asians reflects a large-scale spread of western Iranian farmers east. Instead, sampled ancient genomes from the Iranian plateau and IVC descend from different groups of hunter-gatherers who began farming without being connected by substantial movement of people.

Abstract
Despite academic efforts to study the Indus Valley Civilization (IVC), there have as yet been no successful attempts to unveil the IVC people's craniofacial appearance. We investigated the IVC cemetery area of Rakhigarhi site, which was estimated to be of 2273 ± 38 and 2616 ± 73 years BCE. By craniofacial reconstruction (CFR) procedure using computed tomography (CT) data of two Rakhigarhi skulls (A1 BR02 and A2 BR36), we successfully reconstructed the faces of the IVC individuals who were buried about 4500 years ago. This is the first attempt to unveil scientifically accurate representations of IVC people's actual facial morphology.

Abstract
Background & objectives Climate change is an emerging issue particularly in the context of vector-borne diseases. A study was undertaken in Nainital and Almora districts of Uttarakhand to provide evidences of changing climatic conditions, abundance of vectors, and knocking of malaria in hilly areas. Material and methods Longitudinal data on temperature and relative humidity were procured from Tussar Silk Centre, Bhimtal, India as well as generated using HOBO device. Monthly density of malaria vectors, their positivity for sporozoite proteins of malaria parasite and fever surveys were conducted as per the standard procedures from 2010 to 2013. Epidemiological data were procured from the State Programme Officer of Uttarakhand state. Results It was found that the temperature has increased since 1990 resulting in extension in windows of malaria transmission, temporal distribution as well as man hour density of Anopheles culicifacies and An. fluviatilis in hilly districts of Uttarakhand state. Both the vectors were found in high density up to a maximum man hour density of 110 (An. culicifacies) and 69 (An. fluviatilis) as compared to 32 and 33, respectively during 1998. The field collected vector species were also found positive for sporozoite proteins of malaria parasites in the month of October and November. Evidence of occurrence of malaria cases was also found in areas hitherto free from malaria. Interpretation & conclusion The findings reveal that Himalayan region needs attention to strengthen surveillance for malaria to identify emerging new foci of malaria transmission in view of climate change. Health education to communities about preventive measures to contain breeding of vectors and seeking timely treatment should be imparted so as to achieve the goal of malaria elimination in category-1 in the first instance.

Abstract
The Harappan Civilization, one of the earliest complex societies in the world, flourished on the Indian subcontinent. Although many additional Harappan settlements and cemeteries have been discovered and investigated, no coupled burials at Harappan cemeteries have been reported to date. In 2013–2016, we excavated the cemetery of the Rakhigarhi site (Haryana), the largest city of the Harappan Civilization. At the site, we found a grave that turned out to be a coupled (joint) burial of the primary type. This report is the first anthropologically confirmed case of coupled burial from a Harappan cemetery.

Abstract
An insufficient number of archaeological surveys has been carried out to date on Harappan Civilization cemeteries. One case in point is the necropolis at Rakhigarhi site (Haryana, India), one of the largest cities of the Harappan Civilization, where most burials within the cemetery remained uninvestigated. Over the course of the past three seasons (2013 to 2016), we therefore conducted excavations in an attempt to remedy this data shortfall. In brief, we found different kinds of graves co-existing within the Rakhigarhi cemetery in varying proportions. Primary interment was most common, followed by the use of secondary, symbolic, and unused (empty) graves. Within the first category, the atypical burials appear to have been elaborately prepared. Prone-positioned internments also attracted our attention. Since those individuals are not likely to have been social deviants, it is necessary to reconsider our pre-conceptions about such prone-position burials in archaeology, at least in the context of the Harappan Civilization. The data presented in this report, albeit insufficient to provide a complete understanding of Harappan Civilization cemeteries, nevertheless does present new and significant information on the mortuary practices and anthropological features at that time. Indeed, the range of different kinds of burials at the Rakhigarhi cemetery do appear indicative of the differences in mortuary rituals seen within Harappan societies, therefore providing a vivid glimpse of how these people respected their dead.

Abstract
BACKGROUND Subclinical hypothyroidism (SCH) is a commonly encountered entity in day-to-day clinical practice and has been associated with adverse cardiovascular risk profile in adults and children. Data on children and adolescents with SCH, from India, are limited. MATERIALS AND METHODS This study was a cross-sectional case-control study, conducted at a tertiary care center in Northeast India. Twenty-seven children and adolescents aged 11 ± 2.4 years with SCH and thyroid-stimulating hormone >7.5 mIU/L were included in the study along with 20 age-, gender-, and height-matched controls. Multiple clinical, biochemical, and radiological cardiovascular risk factors were assessed and compared between the two groups. RESULTS Body mass index (BMI) (P = 0.048), waist circumference (P = 0.008), waist to height ratio (P = 0.007), low-density lipoprotein cholesterol (P = 0.04), triglycerides (TGs) (P = 0.038), TGs to high-density lipoprotein (HDL) cholesterol ratio (P = 0.005), non-HDL cholesterol (P = 0.019), fasting insulin (P = 0.006), and homeostasis model assessment of insulin resistance (P = 0.007) were found to be significantly higher while free T4 (P = 0.002) and HDL cholesterol (P = 0.019) were found to be significantly lower in SCH subjects compared to controls. On multiple regression analysis, BMI was found to have significant association with multiple cardiovascular risk factors. CONCLUSION Children and adolescents with SCH were found to have adverse cardiovascular risk profile. Long-term follow-up studies are required to assess the clinical significance of these findings and requirement for therapy.

Abstract
BACKGROUND & OBJECTIVES The influence of temperature on the life cycle of mosquitoes as well as on development of malaria parasite in mosquitoes is well studied. Most of the studies use outdoor temperature for understanding the transmission dynamics and providing projections of malaria. As the mosquitoes breed in water and rest usually indoors, it is logical to relate the transmission dynamics with temperature of micro-niche. The present study was, therefore, undertaken to understand the influence of different formats of temperature of different micro-niches on transmission of malaria for providing more realistic projections. METHODS The study was conducted in one village each of Assam and Uttarakhand s0 tates of India. Temperatures recorded from outdoor (air) as well as indoor habitats (resting place of mosquito) were averaged into daily, fortnightly and monthly and were used for determination of transmission windows (TWs) for Plasmodium vivax (Pv) and P. falciparum (Pf) based on minimum temperature threshold required for transmission. RESULTS The daily temperature was found more useful for calculation of sporogony than fortnightly and monthly temperatures. Monthly TWs were further refined using fortnightly temperature, keeping in view the completion of more than one life cycle of malaria vectors and sporogony of malaria parasite in a month. A linear regression equation was generated to find out the relationship between outdoor and indoor temperatures and R [2] to predict the percentage of variation in indoor temperature as a function of outdoor temperature at both localities. INTERPRETATION & CONCLUSIONS The study revealed that the indoor temperature was more than outdoors in stable malarious area (Assam) but fluctuating in low endemic area like Uttarakhand. Transmission windows of malaria should be determined by transforming outdoor data to indoor and preferably at fortnightly interval. With daily recorded temperature, sporogonic and gonotrophic cycles can also be calculated which is otherwise not possible with monthly data. The study highlights that the projections made for malaria in view of climate change need to be seen with limitation of difference in outdoor and indoor temperatures at different locations, highlighting the need for local data generation at least at sub-district level.

Abstract
Background Turner syndrome (TS) is a chromosomal disorder associated with dysmorphic features and comorbidities, with recent trends focusing on early diagnosis for adequate management. Aim The aim is to study the age and mode of presentation of TS, associated comorbidities and look for any correlation with the genotype. Material and Methods This was a retrospective analysis of girls with TS attending the endocrinology clinic of a tertiary care center. Their age, mode of presentation, and clinical features were noted. All participants underwent ear examination, echocardiography, and ultrasonography of the abdomen. Laboratory investigations included serum T4, thyroid-stimulating hormone, thyroid peroxidase antibodies, follicle-stimulating hormone, fasting, and 2-h plasma glucose after 75 g glucose load and a karyotype. Simple descriptive statistical methods were used. Results Seventeen cases of TS were seen with a median age of presentation of 18 years (range 14-42 years). Primary amenorrhea was the most common reason for seeking medical attention (76.4%) followed by short stature and diabetes mellitus (11.8% each). The mean height at presentation was 137.5 ± 5.4 cm. Monosomy of X chromosome (45,X) was the most common karyotype obtained in 58.8% of the patients, followed by 45,X/46, XX in 17.6%, 45,X/46X,i(X)(q10) in 11.8%, and 45,X/47,XXX and 46X,delXp11.2 in 5.9% patients each. Bicuspid aortic valve was seen in two patients having a 45,X/46,XX karyotype. Conclusion Primary amenorrhea is the most common presenting feature in girls with TS leading to a delayed age of presentation. Short stature and dysmorphic features are often overlooked in infancy and childhood due to socioeconomic factors. This late age of presentation is a cause of concern as early detection and management is important for height outcomes, bone health, and psychosocial support. Assessment of comorbidities becomes important in this setting.

Abstract
Abstract
Triple-negative breast cancer (TNBC) is an aggressive form of cancer occurring in 15-20% of breast cancer patients, with most patients relapsing on currently approved therapy. Recent studies have shown activity of platinum chemotherapy in this class of patients. IO-125 is a novel platinum (II) chemotherapeutic agent with an unique coordination environment. In this study, we investigated the anti-tumor activity of IO-125 in pre-clinical models of TNBC.
The coordination environment in IO-125 facilitates supramolecular assembly and releases diaminocyclohexane (DACH)-platinum in a sustained pH-dependent manner. In vitro cell viability studies using an array of breast cancer cell lines shows IO-125 exerts increased potency compared to carboplatin or oxaliplatin. The maximum tolerated (platinum-equivalent) dose (MTD) of IO-125 in mice was 8-fold higher than the MTD (platinum-equivalent) dose of oxaliplatin. The biodistribution and pharmacokinetic profile of IO-125 in plasma and tumor revealed preferential tumor accumulation, significantly increased area-under-the-curve (AUC), a reduction in clearance (CL) and a longer terminal half-life (42 hours) in comparison to oxaliplatin (18 hours). In addition, DNA-Pt adduct formation in tumors was significantly higher for IO-125. When administered at their respective MTDs, IO-125 led to sustained regression of the tumor in a 4T1 syngeneic breast cancer model. Based on these observations, we conclude that IO-125 may emerge as a novel therapeutic against triple negative breast cancer.

Abstract
The conventional method for creating targeted contrast agents is to conjugate separate targeting and fluorophore domains. A new strategy is based on the incorporation of targeting moieties into the non-delocalized structure of pentamethine and heptamethine indocyanines. Using the known affinity of phosphonates for bone minerals in a model system, two families of bifunctional molecules that target bone without requiring a traditional bisphosphonate are synthesized. With peak fluorescence emissions at approximately 700 or 800 nm, these molecules can be used for fluorescence-assisted resection and exploration (FLARE) dual-channel imaging. Longitudinal FLARE studies in mice demonstrate that phosphonated near-infrared fluorophores remain stable in bone for over five weeks, and histological analysis confirms their incorporation into the bone matrix. Taken together, a new strategy for creating ultra-compact, targeted near-infrared fluorophores for various bioimaging applications is described.

Abstract
BACKGROUND & OBJECTIVES Prevalence of gestational diabetes mellitus (GDM) is known to vary widely depending on the region of the country, dietary habits, and socio-economic status. This study was undertaken to determine the prevalence of GDM and risk factors associated with it, in women attending an antenatal care (ANC) clinic at a tertiary care hospital in Haryana. METHODS This study enrolled women, with their estimated gestational age between 24th and 28th week, attending antenatal care (ANC) clinic at a tertiary care hospital in Rohtak. After informing, women who consented to participate were given a standardized 2-h 75 g oral glucose tolerance test (OGTT). A proforma containing general information on demographic characteristics, socio-economic status, education level, parity, family history of diabetes and/or hypertension and past history of GDM was filled up. American Diabetes Association (ADA) criteria for 75 g 2-h OGTT was used for diagnosing GDM. RESULTS A total of 607 women participated in the study and GDM was diagnosed in 43 (7.1%) women. A single abnormal value was observed in additional 66 (10.87%) women. On bivariate analysis risk factors found to be significantly associated with GDM were age, educational level, socio-economic status, pre-pregnancy weight and BMI, weight gain, acanthosis nigricans, family history of diabetes or hypertension and past history of GDM but on multivariate analysis only upper middle class and presence of acanthosis nigricans were found to be significantly associated with GDM. INTERPRETATION & CONCLUSIONS The prevalence of GDM was found to be 7.1 per cent in a tertiary care hospital in Haryana. Appropriate interventions are required for control and risk factor modifications.

Abstract
Variations in the venous architecture of the retro peritoneum is not uncommon, mostly those of Inferior Vena Cava (IVC). In this report we describe an extremely rare anatomical entity, where the IVC is formed by the union of the right common iliac vein and the left internal iliac vein. This is associated with a parallel venous channel which is the upward continuation of the left external iliac vein, which finally drains into the IVC at the level of renal veins. Awareness of such unusual variation of abdominal venous channels is helpful during retroperitoneal and laparoscopic surgeries of the abdomen, in staging of abdominal neoplasm, in radiological interpretation as well as therapeutic intervention in cases of recurrent pulmonary embolism.

Abstract
We report a case where the median nerve accompanied by brachial vessels were found to traverse an intra-muscular tunnel within the brachialis muscle, in the floor of the cubital fossa. The muscular tunnel commenced 5 cm proximal to the neck of radius, measured 4.4 cm in length, and was present unilaterally. This unusual tunnel was distally found to blend with the brachial fascia. The present study was planned with an endeavor to elucidate in an improved way the clinical implications of compressed median nerve and brachial vessels. There are several sites where median nerve maybe compressed along its course in the arm and forearm. The relevance of the present documentation lies in the fact that these vital neurovascular structures may be compressed leading to neuropathies and vascular changes.

Abstract
A cadaveric study was undertaken to report the incidence of sternalis muscle in cadavers of Asian origin. A total of 88 cadavers were studied over a period of six years and the sternalis was reported only in a single case and that too unilaterally. The accessory muscle was discovered in the right pectoral region in a 40-year-old male cadaver. The muscle emanated from the external oblique aponeurosis of abdomen confirming its origin from the ventral longitudinal sheet of muscle. The muscle was fleshy throughout its extent except at the ends where they were aponeurotic. At the sternal angle, the muscle displayed "Y" shaped configuration and merged with the respective sternocleidomastoid muscle. The innervation was derived from the third intercostals nerve. We intend to highlight a few points through this study. Firstly, we found a paucity of studies undertaken to describe the incidence of sternalis muscle. Further, the studies present in anatomical archives are mainly case reports. Secondly, this muscle presents itself in varying configurations on radiological studies. The radiologist should acquaint himself with all these presentations, so that he can make accurate diagnosis of a breast mass. Thirdly, this muscle having more morphological relevance may be conveniently utilized for flap procedures of post mastectomy breast reconstruction. Lastly, the presence of this muscle may alter the depth at which the internal mammary lymph nodes are irradiated in case of carcinoma breast. Additionally, it should not be erroneously diagnosed as a mass which recurred on follow up of breast cancer patients. The present investigation endeavors to discuss the anatomical, embryological and clinical relevance of a rare accessory muscle of the anterior chest wall.
