There are proponents of decompressive craniectomy (DC) and its various modifications who claim reasonable clinical outcomes for each of them. Clinical outcome in cases of traumatic brain injury, managed conservatively or aided by different surgical techniques, depends on multiple factors, which vary widely among patients and have complex interplay, making it difficult to compare one case with another in absolute terms. This forms the basis of the perceived necessity to have a standard model to study, compare, and strategize in this field. We designed a phantom-based model and present the findings of the study aimed at establishing a correlation of the volume of intracranial space and changes in intracranial pressure (ICP) with surface area of the craniectomy defect created during DC and brain herniation volume. A roughly hemispherical radio-opaque container was scanned on a 128-slice computed tomography scanner. Craniectomies of different sizes and shapes were marked on the walls of the phantom. Two spherical sacs of stretchable materials were subsequently placed inside the phantom, fixed to three-way connectors, filled with water, and connected with transducers. The terminals of the transducer cables were coupled with the display monitor through a signal amplifier and processor module. Parts of the wall of the phantom were removed to let portions of the sac herniate through the defect, simulating a DC. Volume measurements using AW volume share 7? software were done. Resection of a 12.7???11.5?cm part of the wall resulted in a 10-cm-diameter defect in the wall. Volume differential of 35?mL created a midline shift of 5?mm to the side with lesser volume. When measuring pressure in two stretchable sacs contained inside the phantom, there always remained a pressure differential ranging from 1 to 2?mm Hg in different recordings, even with sacs on both sides containing an equal volume of fluids. Creating a circular wall defect of 10?cm in diameter with an intracavitary pressure of 35?mm Hg on the ipsilateral sac and 33?mm on the contralateral sac recorded with intact walls, resulted in a true volume expansion of 48.411?cm3. The herniation resulted in a reduction of pressure in both sacs, with the pressure recorded as 25?mm in the ipsilateral sac and 24?mm in the contralateral sac. The findings closely matched those of the other model-based studies. Refinement of the materials used is likely to provide a valid platform to study cranial volume, ICP, craniectomy size, and brain prolapse volume in real time. The model will help in pre-operatively choosing the most appropriate technique between a classical DC, a hinge craniotomy, and an expansive cranioplasty technique in cases of refractory raised ICP.

Traceability is a transparent quality index in almost every supply chain. Especially when it comes to highly perishable products, such as dairy, the need for an effective traceability system is unavoidable due to increased fraudulent products, adulteration, excessive additives, and toxic substances.

The developed snack is a functional food for the consumers.

Transistors find application within various integrated circuits (ICs) alongside a multitude of electronic devices. These ICs have become integral components in contemporary systems. When organic semiconducting materials constitute the active layer, transistors are termed “organic transistors.” The enhancement of diverse device characteristics is achievable through the modeling and simulation of these organic transistors. This study focuses on the simulation of different configurations of pentacene-based organic transistors. To augment device performance, an active layer comprising pentacene is coupled with 5 and 15 nm graphene. Notably, the top gate configuration yields an increase in ON/OFF ratio from 102 to 107, accompanied by an enhancement in sub-threshold swing from 276 to 59 mV/decade. Similarly, the bottom gate configuration exhibits an ON/OFF ratio improvement from 105 to 109, alongside a sub-threshold swing enhancement from 108 to 59 mV/decade. Leveraging graphene as the active layer material results in substantial benefits. These encompass a heightened on-current of 210 mA, a reduced sub-threshold swing of 58 mV/decade, and a significantly enhanced ON/OFF ratio of 1017.

The food waste of the fruit processing industry is rich in many bio-active components such as polysaccharides, polyphenols, peptides, etc. that own multifaceted health benefits. The valorization of this waste is an intriguing optimization method for various dairy products. Meanwhile, LC-MS-based foodomics has been an emerging approach for the quantitative and qualitative analysis of dairy foods. Untargeted metabolomics has been done of the optimized functional yogurt that contains different levels of unripened papaya peel powder (UPPP) using high-resolution mass spectroscopy for analysis of added bio-active components in the matrix. UPPP comprises a high content of phytochemicals which could give functionality and therapeutic effect to the Greek yogurt. A total of 36 functional metabolites have been identified which have various health-beneficial attributes. Kaempferol, ostruthin, putative carpaine derivatives, etc. are some of the metabolites of high importance with a wide area coverage in the metabolome. This work highlights the bioactivity of the UPPP and its prebiotic properties added to the functional yogurt as an independent ingredient. The incorporated plant-based ingredients like UPPP can effectively enhance the functional attributes of Greek yogurt, which is a potential synbiotic food.

The crop water requirement of rice in different agroclimatic zones of Jharkhand, India was estimated using the CROPWAT 8.0 and CLIMWAT 2.0 models with data collected through NASA data-access-viewer on climate, soil, crop, and water availability. The evapotranspiration (ETo), effective rainfall (Peff), and crop water requirement (CWR) for the four zones of the Jharkhand State were calculated. Results revealed that the reference evapotranspiration (ETo) varied from 420.4 mm to 516.5 mm during the crop growing season of rice in different zones. The effective precipitation varied from 748.4 mm to 760.8 mm. The crop water requirement of rice varied from 482.5 mm to 592.4 mm. Effective rainfall was sufficient to meet the water requirement of rice in most of the zones except Alluvial zone wherein the net irrigation water requirement was only 67.6 mm.

Cancer stem cells represent a resilient subset within the tumor microenvironment capable of differentiation, regeneration, and resistance to chemotherapeutic agents, often using dormancy as a shield. Their unique properties, including drug resistance and metastatic potential, pose challenges for effective targeting. These cells exploit certain metabolic processes for their maintenance and survival. One of these processes is autophagy, which generally helps in energy homeostasis but when hijacked by CSCs can help maintain their stemness. Thus, it is often referred as an Achilles heel in CSCs, as certain cancers tend to depend on autophagy for survival. Autophagy, while crucial for maintaining stemness in cancer stem cells (CSCs), can also serve as a vulnerability in certain contexts, making it a complex target for therapy. Regulators of autophagy like AMPK (5′ adenosine monophosphate-activated protein kinase) also play a crucial role in maintaining CSCs stemness by helping CSCs in metabolic reprogramming in harsh environments. The purpose of this review is to elucidate the interplay between autophagy and AMPK in CSCs, highlighting the challenges in targeting autophagy and discussing therapeutic strategies to overcome these limitations. This review focuses on previous research on autophagy and its regulators in cancer biology, particularly in CSCs, addresses the remaining unanswered questions, and potential targets for therapy are also brought to attention.

Alzheimer’s disease (AD) is the most prevalent neurodegenerative disorder and affects millions of individuals globally. AD is associated with cognitive decline and memory loss that worsens with aging. A statistical report using U.S. data on AD estimates that approximately 6.9 million individuals suffer from AD, a number projected to surge to 13.8 million by 2060. Thus, there is a critical imperative to pinpoint and address AD and its hallmark tau protein aggregation early to prevent and manage its debilitating effects. Amyloid-β and tau proteins are primarily associated with the formation of plaques and neurofibril tangles in the brain. Current research efforts focus on degrading amyloid-β and tau or inhibiting their synthesis, particularly targeting APP processing and tau hyperphosphorylation, aiming to develop effective clinical interventions. However, navigating this intricate landscape requires ongoing studies and clinical trials to develop treatments that truly make a difference. Genome-wide association studies (GWASs) across various cohorts identified 40 loci and over 300 genes associated with AD. Despite this wealth of genetic data, much remains to be understood about the functions of these genes and their role in the disease process, prompting continued investigation. By delving deeper into these genetic associations, novel targets such as kinases, proteases, cytokines, and degradation pathways, offer new directions for drug discovery and therapeutic intervention in AD. This review delves into the intricate biological pathways disrupted in AD and identifies how genetic variations within these pathways could serve as potential targets for drug discovery and treatment strategies. Through a comprehensive understanding of the molecular underpinnings of AD, researchers aim to pave the way for more effective therapies that can alleviate the burden of this devastating disease.

Introduction: The health benefits of physical activity are well established. In India, it is estimated that overall, 39.2 crore individuals are physically inactive. The trends of physical inactivity among Indian adolescent and youth populations are also alarming which implies that a huge population is at risk for developing NCDs. Objective: To assess physical activity levels among MBBS students. Method: The study was conducted at a medical institute in Uttar Pradesh. Sample size of 342 was drawn using stratified random sampling. The data collection was done based on “IPAQ- short form” using self-administered questionnaire. Data analysis was done as prescribed by the IPAQ-SF tool kit. Results: A total of 342 MBBS students participated in the study. Mean age of the participants was 20.86 years (Range 18-26 years). A total of 117(34.2%) medical students were found to be “insufficiently active” (Category-1),134 students (39.2%) were just minimally active (Category -2) and rest 91(26.6%) students were HEPA (Health Enhancing Physical Activity) active (Category-3). Median MET- minutes/week and Inter Quartile Range (IQR) for vigorous physical activity was 0(0-640), for moderate activity it was 60(0-320) and for walking it was 462(297-924). Overall total physical activity MET- minutes/week and IQR was 942(401-2066). The median and (IQR) values for sitting were 10(8-12) hours/day. Conclusion: The study reveals that a noteworthy proportion of the participants do not meet the recommended levels of physical activity, indicating a pressing public health concern. Findings necessitate the importance of behaviour change activities to promote physical activity in the study population.

Adequate nutrition is essential for our physical and mental growth and development. It forms the foundation of our very existence as it impacts health outcomes in every stage of life. The importance of nutrition is well recognised in the United Nations, Sustainable Development Goal (SDG)-2 as “Zero Hunger” which aims to promote food security for all and end hunger and all forms of malnutrition by 2030. Nutrition is also the key to attainment of other SDG’s as well, with 12 of the 17 SDGs having indicators relevant for nutrition.

Molecular chaperones are highly conserved across evolution and play a crucial role in preserving protein homeostasis. The 60 kDa heat shock protein (HSP60), also referred to as chaperonin 60 (Cpn60), resides within mitochondria and is involved in maintaining the organelle’s proteome integrity and homeostasis. The HSP60 family, encompassing Cpn60, plays diverse roles in cellular processes, including protein folding, cell signaling, and managing high-temperature stress. In prokaryotes, HSP60 is well understood as a GroEL/GroES complex, which forms a double-ring cavity and aids in protein folding. In eukaryotes, HSP60 is implicated in numerous biological functions, like facilitating the folding of native proteins and influencing disease and development processes. Notably, research highlights its critical involvement in sustaining oxidative stress and preserving mitochondrial integrity. HSP60 perturbation results in the loss of the mitochondria integrity and activates apoptosis. Currently, numerous clinical investigations are in progress to explore targeting HSP60 both in vivo and in vitro across various disease models. These studies aim to enhance our comprehension of disease mechanisms and potentially harness HSP60 as a therapeutic target for various conditions, including cancer, inflammatory disorders, and neurodegenerative diseases. This review delves into the diverse functions of HSP60 in regulating proteo-homeostasis, oxidative stress, ROS, apoptosis, and its implications in diseases like cancer and neurodegeneration.

The heat shock response is an evolutionarily conserved mechanism that protects cells or organisms from the harmful effects of various stressors such as heat, chemicals toxins, UV radiation, and oxidizing agents. The heat shock response triggers the expression of a specific set of genes and proteins known as heat shock genes/proteins or molecular chaperones, including HSP100, HSP90, HSP70, HSP60, and small HSPs. Heat shock proteins (HSPs) play a crucial role in thermotolerance and aiding in protecting cells from harmful insults of stressors. HSPs are involved in essential cellular functions such as protein folding, eliminating misfolded proteins, apoptosis, and modulating cell signaling. The stress response to various environmental insults has been extensively studied in organisms from prokaryotes to higher organisms. The responses of organisms to various environmental stressors rely on the intensity and threshold of the stress stimuli, which vary among organisms and cellular contexts. Studies on heat shock proteins have primarily focused on HSP70, HSP90, HSP60, small HSPs, and ubiquitin, along with their applications in human biology. The current review highlighted a comprehensive mechanism of heat shock response and explores the function of heat shock proteins in stress management, as well as their potential as therapeutic agents and diagnostic markers for various diseases.

This work accounts for the green synthesis of iron oxide nanoparticles using Moringa oleifera leaf extract as a stabilizing and reducing agent. The preliminary confirmation of synthesized Fe3O4NPs was done by UV–visible spectroscopy in the wavelength range of 190–900 nm. The crystalline nature of Fe3O4 NPs was established via X-ray diffraction analysis. FT-IR studies reveal the bioactive phytochemicals present in the Moringa leaf extract based Fe3O4 NPs. A DLS particle size analyser was used to determine the size of green synthesized Fe3O4 NPs and its spherical morphology was determined by using SEM and TEM techniques. The growth of Brassica oleracea var. italica seedlings was measured by analysing biophysical and biochemical parameters in two concentrations of Fe3O4 NPs i.e. 15 mg/L and 30 mg/L alone and in combination with cadmium. Treatments were designated as control C, NP1, NP2, Cd+NP1, Cd+NP2, and Cd. Fe3O4 NPs treated broccoli seedlings showed noteworthy improvement in shoot length, root length, plant biomass, total chlorophyll content, carotenoid content, total soluble sugars, protein content, and nitrate reductase activity, while decline in electrolyte leakage, lipid peroxidation, proline content, superoxide dismutase activity and catalase activity was reported as compared to control. Exposure of iron oxide nano-treatments was found efficacious in reducing cadmium accumulation at a concentration of 30 mg/L. The seedlings exposed to NP2 (30 mg/L) concentration of green synthesized nano iron oxide increased nutrient uptake and thus stimulating plant growth, and also improved morphological and physiological characteristics of Brassica oleracea seedlings. Therefore, the present study reported that bio-based iron oxide nanoparticles were significantly useful for plant growth, by enhancing the plant defense mechanism in response to cadmium induced toxicity.

Limited availability of the organs donors has facilitated the establishment of xenogeneic organ sources for transplantation. Numerous studies have decellularized several organs and assessed their implantability in order to provide such organs. Among all the decellularized organs studies for xenotransplantation, the pancreas has garnered very limited amount of research. The presently offered alternatives for pancreas transplantation are unable to liberate patients from donor dependence. The rat and mice pancreas are not of an accurate size for transplantation but can only be used for in-vitro studies mimicking in-vivo immune response in humans, while the porcine pancreas can cause zoonotic diseases as it carries porcine endogenous retrovirus (PERV- A/B/C). Therefore, we propose caprine pancreas as a substitute for these organs, which not only reduces donor dependence but also poses no risk of zoonosis. Upon decellularization the extracellular matrix (ECM) of different tissues responds differently to the detergents used for decellularization at physical and physiological level; this necessitates a comprehensive analysis of each tissue independently. This study investigates the impact of decellularization by ionic (SDS and SDC), non-ionic (Triton X-100 and Tween-20), and zwitterionic detergents (CHAPS). All these five detergents have been used to decellularize caprine pancreas via immersion (ID) and perfusion (PD) set-up. In this study, an extensive comparison of these two configurations (ID and PD) with regard to each detergent has been conducted. The final obtained scaffold with each set-up has been evaluated for the left-over cytosolic content, ECM components like sGAG, collagen, and fibronectin were estimated via Prussian blue and Immunohistochemical staining respectively, and finally for the tensile strength and antimicrobial activity. All the detergents performed consistently superior in PD than in ID. Conclusively, PD with SDS, SDC, and TX-100 successfully decellularizes caprine pancreatic tissue while retaining ECM architecture and mechanical properties. This research demonstrates the viability of caprine pancreatic tissue as a substitute scaffold for porcine organs and provides optimal decellularization protocol for this xenogeneic tissue. This research aims to establish a foundation for further investigations into potential regenerative strategies using this ECM in combination with other factors.

Background: The boom in clinical research/clinical trials (CR/CT) has generated valuable knowledge in the field of medical science. India has been a promising CT sector, but witnesses' only modest involvement from participants. The lack of awareness is possibly one of the factors that has led to stagnated growth of this sector. Objective: To assess the awareness and perception of participants to CR/CT and their willingness to participate. Methods: A cross-sectional online survey with a questionnaire comprising 25 questions. The survey was implemented at secondary and higher secondary schools, colleges/institutes as well as patient advocacy group. Results: A total of 852 participants participated in the online survey having median age 21 (Interquartile range: 20–28) years. More than 85% of participants were aware of CR/CT. The source of information was majorly contributed by hospitals (44.2%), social media (40.2%), and print media (40.2%). The perception about CT was reported as possibility of new treatment (63.4%) and more useful than traditional treatment (52.5%). More than half of the participants were willing to participate in CR involving questionnaire surveys (39.2%), research done together with administration of standard medical care (3.7%), and single blood draw/visit (34.7%). The survey reflected an unwillingness to participate in CR/CT due to concerns about safety (59.7%) and fear (50.8%). Conclusion: This survey showed that there has been increasing awareness and willingness to participate in CR/CT. However, to increase the participation, there is a need to address the concerns of safety and fear.

INTRODUCTION: Serum erythropoietin (S. EPO) continues to be a minor diagnostic criterion for discriminating polycythemia vera (PV) from other causes of erythrocytosis. However, in the current era of Janus kinase 2 (JAK2) mutation testing, its relevance for establishing the diagnosis of PV is controversial. AIMS AND OBJECTIVES: The study aimed to assess the utility of S. EPO in patients with absolute erythrocytosis and ascertain its sensitivity and specificity for establishing the diagnosis of PV. Further, the clinicopathological features of PV and JAK2-EPOlow erythrocytosis were compared to discriminate the two disease states. MATERIALS AND METHODS: A total of 286 samples had undergone concomitant testing for S. EPO levels and JAK2V617F mutation for various indications over a period of 60 months (January 2017–December 2021). Clinical details and laboratory parameters were retrieved from the electronic medical records. RESULTS: Among 203/286 (70%) patients with erythrocytosis, JAK2 positivity was noted in 49 (24.1%) patients. A subnormal S. EPO level (16.5 g/dL) with low S. EPO and for diagnosing PV was 62.7% and 79.0%, respectively, while the sensitivity of high Hb levels with JAK2 positivity was 89.7%. In addition, 14.7% (30/203) of cases of high Hb/hematocrit (median: 18 g/dL and range: 16.3–23.8 g/dL) belonged to the JAK2-EPOlow subgroup. The median age of these patients, red blood cell count, total leukocyte count, and platelet count were, however, significantly lower as compared to the PV (P < 0.05). CONCLUSION: Overall, a low sensitivity and specificity of S. EPO were observed for diagnosing PV as an isolated investigation, thus questioning its diagnostic utility, though high levels had an excellent negative predictive value. However, this simple and inexpensive test remains an important screening tool for evaluating patients with absolute erythrocytosis.

Background: Minimally invasive and percutaneous treatments are effective treatment options for idiopathic trigeminal neuralgia (TN).Objectives: Multiple approaches have been described for the treatment of TN. This narrative review has been done to evaluate the current literature on different percutaneous treatment options for TN and to determine whether anyone treatment is better. Methods: The literature through a search of PubMed and Google Scholar was done and the review of the citations of relevant literature, and the authors knowledge of the literature and activity in the field. The literature was reviewed to find the preferred technique of preferred percutaneous treatment by different investigators and the difference in the outcome and/or complications and side effects. Results: Multiple techniques of such as percutaneous retrogasserian glycerol rhizolysis (PRGR), radiofrequency thermal coagulation (RFTC), and percutaneous balloon compression (PBC) for idiopathic TN have been used by different researchers. Effective pain relief and improved quality of life have been reported to be achieved by all the approaches. RFTC has been the most extensively used method, but PBC has been found to be more suitable for corneal preservation in cases of ophthalmic (V1) division pain. The most common imaging method used by large number of researchers is fluoroscope, though few authors have recommended computed tomography scan guidance for placement of cannula in foramen ovale and Meckle's cave, especially in cases with difficult anatomy. Limitations: This review has focused only on percutaneous techniques used by pain physicians. Other techniques such as radiosurgery and gamma knife used by radiologists and neurologists are not included. Conclusions: minimally invasive and percutaneous treatments such as PRGR, RFTC, and PBC are effective methods for the treatment of idiopathic TN. Selection of approach is largely dependent on the pain physician's choice, experience, and equipment available and can be used interchangeably; although for V1 neuralgia, PBC has superiority due to the preservation of corneal reflex.

Background: During the COVID-19 pandemic, Anganwadi workers (AWWs) were repositioned for community support, community surveillance, community awareness on infection prevention and mitigating stigma/discrimination entailing infection, going door to door. The job entailed good knowledge, attitude and practices (KAP) with regard to infection prevention and control (IPC). Aims: To assess the KAP of AWW with regard to IPC in context of COVID-19 in Lucknow district. Methods: A cross-sectional survey was conducted using Google form between 30 June and 28 July 2020. AWWs were recruited from Lucknow district irrespective of their training status; data analysis was done on 137 participants. The mean KAP score was calculated and student t-test was applied. Chi-square test was performed between categorical variables and KAP. Univariate and multivariate logistic regression was applied between independent and dependent variables. Results: The mean score of knowledge was 7.22 ± 2.64, attitude was 4.34 ± 1.14 and practice was 4.44 ± 1.11. There was a significant difference between good and poor score for KAP. Participants with older age, good knowledge and attitude scores were more likely to have good practices. Conclusion: AWWs had good attitude and practices, but lacked adequate knowledge on IPC measures. Ensuring training for AWW on IPC is important.

BACKGROUND: In clinical practice, laboratory results are of great importance for the diagnosis and treatment. Reference intervals of different parameters aid health-care professionals in the interpretation of results. There are very few studies on reference intervals from India. This prospective study was conducted to determine the reference intervals for platelet count (PLT) and PLT indices; mean PLT volume (MPV), PLT distribution width (PDW), and PLT large cell ratio (P-LCR). These values can be obtained as a part of a routine complete blood count (CBC) and have diagnostic and prognostic significance in certain diseases. PLT count is an important criterion for the selection of donors for repeat plateletpheresis donation. MATERIALS AND METHODS: Sixteen hundred and thirty-four first-time healthy volunteer plateletpheresis donors were enrolled for the study. CBC was done, values of PLT, MPV, PDW, and P-LCR were noted, and the results were analyzed. The 95% of the reference distribution was estimated using the 2.5th and 97.5th percentiles following Clinical and Laboratory Standards Institute guidelines. Adverse donor reactions, if any and quality parameters of single donor PLTs (SDP) were also studied. RESULTS: Reference range values of PLT, MPV, PDW, and P-LCR were 137,825–355,175/μl, 8.1–13.9/fl, 9.1–22.5/fl, and 11.7%–52.9%, respectively, and compared well with other published studies from India. It was observed that reference values of PLT count obtained in the study were lower than reference values that are currently used in most laboratories (150,000–450,000/μl) in India. CONCLUSION: Based on our results, we are of the opinion that the PLT count cutoffs for repeat plateletpheresis donation may need to be revised downwards for our country which would also mitigate the scarcity of apheresis donors.

Context: “Foundation course” is an orientation program for MBBS students at time of entry into medical college. Aims: To study the MBBS student's perception of relevance and level of confidence in application of skills acquired in foundation course and its predictors. Settings and Design: A cross sectional study was done among second year MBBS students at a medical college in central Uttar Pradesh, India. Methods and Material: Data was collected online using a Google form over 1 month. About 97 (out of 200) students participated in the study. Final analysis was done for 94 responses. Statistical Analysis Used: Chi Square test for proportions. Results: Overall 83% students found foundation course to be relevant. Sessions on professional development & ethics (94.6%), biomedical waste management (94.6%), social responsibility of doctors (91.5%), communication skill (93.6%), role and responsibilities of Indian Medical Graduate (93.6%), universal precautions (91.5%), immunisation (91.5%) and assessing E –resource (90.4%) were rated as most relevant. Computer skills and sports/extra-curricular activities were perceived as non-relevant by 29% and 16% students respectively. Overall 61% students were confident about application of knowledge/skills acquired in the foundation course. A significant difference was observed for gender and medium of education with regards to level of confidence in application of certain skills/knowledge. Conclusions: Foundation course was perceived as relevant by most students. However, level of confidence with regards to application of skills/knowledge was found to be variable with significant difference for some variables.

Abstract Background Acute respiratory distress syndrome is an important clinical presentation of respiratory complications caused by severe acute respiratory syndrome coronavirus 2, a novel coronavirus responsible for the ongoing pandemic. The disease is poorly understood, and immunopathogenesis is constantly evolving. Cytokine release syndrome remains central to pathology of coronavirus disease 2019. Antivirals, anticytokine treatment, and other pharmacological approaches have failed to treat it. CytoSorb, an extracorporeal cytokine adsorber that reduces the cytokine storm and other inflammatory mediators in the blood, seems promising in treating severely ill patients with coronavirus disease 2019. Case presentation This article presents three cases of Asian ethnicity of severely ill adult patients with coronavirus disease 2019 admitted to intensive care unit who were treated with CytoSorb therapy. All patients used single CytoSorb device. During their clinical course, all patients were prescribed tocilizumab (an interleukin-6 receptor blocker), antivirals, hydroxychloroquine, azithromycin, and other antibiotics and general antipyretic drugs. No vasopressor treatment was required. The patients’ average duration of stay in intensive care unit was 30 days; the average duration of stay in hospital was 31 days. All three patients showed significant improvement in biochemical parameters and clinical outcomes post CytoSorb therapy. C-reactive protein levels decreased by 91.5%, 97.4%, and 55.75 %, and mean arterial pressure improved by 18%, 23%, and 17 % in patient 1, 2, and 3, respectively, on day 7 post-therapy. Conclusions All three patients improved clinically and survived.

Abstract Background and Aim Type 2 diabetes (T2D) in associated with higher prevalence and worse outcomes of nonalcoholic fatty liver disease (NAFLD). However, data regarding the prevalence of clinically relevant liver fibrosis (CRLF) in Indian individuals with T2D are scarce. We investigated the prevalence of, and factors associated with, CRLF in Indians with T2D. Methods We conducted a prospective study of 601 consecutive adults with T2D. Steatosis was diagnosed using ultrasonography. Liver stiffness measurement (LSM) by transient elastography of ≥8.0 kPa was taken as cutoff suggesting CRLF. Individuals with LSM > 13.0 kPa underwent dynamic magnetic resonance imaging (MRI) of liver for detecting changes consistent with cirrhosis. Results The prevalence of steatosis was 84.2%. Higher body mass index (BMI, P = 0.022), alanine aminotransferase (ALT; P = 0.001), and lower high‐density lipoprotein (HDL; P = 0.002) were independent factors associated with steatosis. The prevalence of CRLF was 28.2%. Higher BMI (P = 0.001), aspartate aminotransferase (AST; P 13.0 kPa. Among them, 25 individuals underwent dynamic MRI of liver, which revealed features consistent with cirrhosis in 18 patients. Conclusion CRLF, an established risk factor for cirrhosis and overall mortality, affects at least one out of four (25%) Indians with T2D. These results support screening of all patients with T2D and NAFLD for liver fibrosis.

Regardless of theoretical backgrounds that assumed a positive association between public expenditure and economic development, the present study on this linkage is inconclusive. This empirical work re-investigates the effect of government expenditure on GDP growth employing more recent dataset spanning the period 1991-2019 in the region of Brazil, Russia, India, China, South Africa (BRICS), Association of South East Asian Nations (ASEAN), and South Asian Association for Regional Cooperation (SAARC). Considering the issues of cross sectional dependence, the estimated findings show long run relationship between government size, inflation, human capital, employment, unemployment, export, and economic growth. The fully modified OLS estimates reveal that government spending has a positive influence on economic development. Further, the analysis indicates that human capital, employment, and export increases economic growth. However, unemployment and inflation have a detrimental effect on economic development. Our result confirms the unidirectional causality between public spending and economic growth, suggesting Keynesian view of public spending in stimulating economic development. The sensitivity of the results have been checked with the help of dynamic OLS estimator.

Abstract Li-ion batteries function by Li intercalating into and through the layered electrode materials. Intercalation is a solid-state interaction resulting in the formation of new phases. The new observations presented here reveal that at the nanoscale the intercalation mechanism is fundamentally different from the existing models and is actually driven by nonuniform phase distributions rather than the localized Li concentration: the lithiation process is a ‘distribution-dependent’ phenomena. Direct structure imaging of 2H and 1T dual-phase microstructures in lithiated MoS2 and WS2 along with the localized chemical segregation has been demonstrated in the current study. Li, a perennial challenge for the TEM, is detected and imaged using a low-dose, direct-electron detection camera on an aberration-corrected TEM and confirmed by image simulation. This study shows the presence of fully lithiated nanoscale domains of 2D host matrix in the vicinity of Li-lean regions. This confirms the nanoscale phase formation followed by Oswald ripening, where the less-stable smaller domains dissolves at the expense of the larger and more stable phases.

Fracture and embolization of peripheral intravenous cannula is very rare. Although endovascular retrieval is the standard of care for most of the embolized intravascular devices, endovascular management of embolized peripheral intravenous cannula is technically difficult due to its radiolucent nature and it is not described previously in the literature. We describe the clinical presentation, imaging findings, and endovascular management in a middle aged male who had fractured peripheral intravenous cannula which was embolized into the pulmonary artery branch. Technical nuances associated with retrieval of this radiolucent little plastic tube have been discussed.

Entangled photons can be used to create a truly secure communication link between two parties. However, the distance over which this can be achieved is limited by the transmission losses associated with optical fibers. One potential solution is using quantum repeaters (QRs) where initial entanglement is created over short distances and then extended via entanglement swapping. The system-level performance metrics (data rate, fidelity of entanglement, etc.) impose demands upon the hardware components (of a QR), which can be used to guide applied materials and device design toward these objectives. This has become increasingly important with an expanding list of candidates for quantum technologies, as the physical realization of each qubit or detector technology brings its own set of advantages and disadvantages. In this article, we present a framework that uses a modular QR and highlights the tradeoffs that exist between technological component modules. Using reported values, we take a near-term perspective and show the achievable range of rates as a function of distance and the corresponding requirements on matter qubit properties.

In a wireless sensor network (WSN), the data transmission technique based on the cooperative multiple‐input multiple‐output (CMIMO) scheme reduces the energy consumption of sensor nodes quite effectively by utilizing the space‐time block coding scheme. However, in networks with high node density, the scheme is ineffective due to the high degree of correlated data. Therefore, to enhance the energy efficiency in high node density WSNs, we implemented the distributed source coding (DSC) with the virtual multiple‐input multiple‐output (MIMO) data transmission technique in the WSNs. The DSC‐MIMO first compresses redundant source data using the DSC and then sends it to a virtual MIMO link. The results reveal that, in the DSC‐MIMO scheme, energy consumption is lower than that in the CMIMO technique; it is also lower in the DSC single‐input single‐output (SISO) scheme, compared to that in the SISO technique at various code rates, compression rates, and training overhead factors. The results also indicate that the energy consumption per bit is directly proportional to the velocity and training overhead factor in all the energy saving schemes.

Background: Ayurvedic clinical profiling of COVID-19 is a pre-requisite to develop standalone and integrative treatment approaches. At present, Ayurvedic clinicians do not have access to COVID-19 patients in clinical settings. In these circumstances, a preliminary clinical profiling of COVID-19 based on review of modern medical and classical Ayurvedic literature with inputs from Allopathic clinicians treating COVID-19 patients assumes significance. Objectives: This paper aims to develop an Ayurvedic clinical profile of COVID-19 by literature review supported by analysis of clinical data of a cohort of COVID-19 patients. Methods: The typical clinical presentation of COVID-19 was categorized based on a cluster of symptoms with reference to “Interim Clinical Guidance for Management of Patients with confirmed corona virus disease (COVID-19)” released by the US CDC. As the clinical presentation is found to vary widely, research papers reporting clinical symptoms of patient samples from different parts of the world were also reviewed to identify outliers and atypical presentations. Case records of fourteen COVID-19 patients treated at Medanta Hospital, Gurgaon were analyzed to compare symptomatology with data obtained from published literature. Further, a careful correlation was done with the data collected from selected Ayurvedic classical texts and expert views of clinical practitioners to arrive at a preliminary Ayurvedic clinical profile of COVID-19. Results: COVID-19 can be understood from the Ayurvedic perspective as vātakapha dominant sannipātajvara of āgantu origin with pittānubandha. The asymptomatic, presymptomatic, mild, moderate, severe and critical stages of COVID-19 with varying clinical presentations have been analysed on the basis of nidāna, doṣa, dūṣya, nidānapañcaka and ṣaṭkriyākāla to present a preliminary clinical profile of the disease. Conclusion: In this paper, we have demonstrated that a preliminary clinical profiling of COVID-19 from the Ayurvedic perspective is possible through literature review supported by discussions with Allopathic clinicians as well as examination of patient case records. The provisional diagnosis proposed can be further developed with continued review of literature, wider cooperation and teamwork with Allopathic physicians and access to clinical data as well as direct clinical assessment of COVID-19 patients.

The use of transmission electron microscopy (TEM) to observe real-time structural and compositional changes has proven to be a valuable tool for understanding the dynamic behavior of nanomaterials. However, identifying the nanoparticles of interest typically require an obvious change in position, size, or structure, as compositional changes may not be noticeable during the experiment. Oxidation or reduction can often result in subtle volume changes only, so elucidating mechanisms in real-time requires atomic-scale resolution or in-situ electron energy loss spectroscopy, which may not be widely accessible. Here, by monitoring the evolution of diffraction contrast, we can observe both structural and compositional changes in iron oxide nanoparticles, specifically the oxidation from a wüstite-magnetite (FeO@Fe _3 O _4 ) core – shell nanoparticle to single crystalline magnetite, Fe _3 O _4 nanoparticle. The in-situ TEM images reveal a distinctive light and dark contrast known as the ‘Ashby-Brown contrast’, which is a result of coherent strain across the core – shell interface. As the nanoparticles fully oxidize to Fe _3 O _4 , the diffraction contrast evolves and then disappears completely, which is then confirmed by modeling and simulation of TEM images. This represents a new, simplified approach to tracking the oxidation or reduction mechanisms of nanoparticles using in-situ TEM experiments.

NAC transcription factors regulate stress-defence pathways and developmental processes in crop plants. However, their detailed functional characterization in tomatoes needs to be investigated comprehensively. In the present study, tomato hybrids subjected to 60 and 80 days of drought stress conditions showed a significant increase in membrane damage and reduced relative water, chlorophyll and proline content. However, hybrids viz., VRTH-16-3 and VRTH-17-68 showed superior growth under drought stress, as they were marked with low electrolytic leakage, enhanced relative water content, proline content and an enhanced activity of enzymatic antioxidants, along with the upregulation of NAC and other stress-defence pathway genes. Candidate gene(s) exhibiting maximum expression in all the hybrids under drought stress were subjected to detailed in silico characterization to provide significant insight into its structural and functional classification. The homology modelling and superimposition analysis of predicted tomato NAC protein showed that similar amino acid residues were involved in forming the conserved WKAT domain. DNA docking discovered that the SlNAC1 protein becomes activated and exerts a stress-defence response after the possible interaction of conserved DNA elements using Pro72, Asn73, Trp81, Lys82, Ala83, Thr84, Gly85, Thr86 and Asp87 residues. A protein–protein interaction analysis identified ten functional partners involved in the induction of stress-defence tolerance.

Background: The aim of this study was to estimate the seroprevalence of spotted fever group (SFG) and typhus group (TG) rickettsiae among individuals with acute febrile illness (AFI) in the scrub typhus endemic district of Gorakhpur in India. This district is one of the worst affected by annual seasonal acute encephalitis syndrome (AES) outbreaks. Methods: Antibodies against SFG and TG rickettsiae and the associated risk factors were determined in 294 individuals presenting with an AFI, encountered during a community-based survey conducted during the AES outbreak period October–November 2016. Results: Respective IgM and IgG seropositivity was 13.6% and 36.7% for SFG, and 7.1% and 15.3% for TG. SFG IgM positivity was significantly higher among females, while IgG positivity was significantly higher among individuals ≥45 years of age. IgM and IgG seropositivity for TG rickettsiae were significantly higher in individuals involved in outdoor activities and housewives, but did not differ according to age group, sex, or educational status. Conclusion: The study results present serological evidence of SFG and TG rickettsiosis, in addition to scrub typhus, among individuals with AFI in Gorakhpur region and indicate the need to explore their roles as potential causes of AES in the region. Keywords: Spotted fever group rickettsiae, Typhus group rickettsiae, Rickettsia conorii, Rickettsia typhi, Indian tick typhus, Murine typhus, Gorakhpur

Background: Lactic acidosis is a rare but serious complication associated with metformin therapy in certain high-risk patients. NICE guidelines and the British National Formulary advise the discontinuation of metformin before surgery. The drug manufacturer's datasheet advises the withdrawal of metformin 48 h before surgery. However, the data regarding perioperative use of metformin is scarce. Aims: To evaluate the effect of continuation of metformin till night before surgery on lactate levels in patients undergoing coronary artery bypass graft (CABG) surgery. Materials and Methods: In this prospective cohort study, 1,800 consecutive patients who underwent CABG between 1st November 2015 and 31st October 2016 were enrolled. Following exclusion criteria, a total of 790 subjects were included for final analysis. Three-hundred and eight seven (48.9%) patients with diabetes received metformin till night before surgery (Met group), 239 (30.3%) patients with diabetes were non-metformin users (Non-Met group), and 164 (20.8%) patients were having no diabetes (Non-Diab group). Lactate levels and arterial pH were measured using arterial blood gas machine. Postoperative morbidity outcome data were obtained by collecting clinical data, routine biochemistry, and chest imaging. Results: The mean metformin dose was 1,124.6 mg/day (SD: 509.3; range: 500–2,500 mg/day). Mean postoperative lactate levels were 1.91 ± 0.7 in Met group, 2.04 ± 0.79 in Non-Met group, and 2.07 ± 0.78 in Non-Diab group. Lactic acidosis occurred in 41 patients and there was no difference among the groups [Met group = 18 (4.7%); Non-Met group = 14 (5.9%)]. Among secondary outcome measures, acute renal failure occurred more frequently in diabetic patients [Met group = 46 (11.9%) and Non-Met group = 32 (13.4%)] as compared with non-diabetic patients. There were no differences with regard to pneumonia, length of ICU stay, and duration of ventilatory support among the three groups. Conclusions: Continuation of metformin till night before surgery is not associated with significant changes in lactate levels in patients undergoing CABG.

The low-and-middle-income country (LMIC) context is volatile, uncertain and resource-constrained. India, an LMIC, has put up a complex response to the COVID-19 pandemic. Using an analytic approach, we have described India’s response to combat the pandemic during the initial months (from 17 January to 20 April 2020). India issued travel advisories and implemented graded international border controls between January and March 2020. By early March, cases started to surge. States scaled up movement restrictions. On 25 March, India went into a nationwide lockdown to ramp up preparedness. The lockdown uncovered contextual vulnerabilities and stimulated countermeasures. India leveraged existing legal frameworks, institutional mechanisms and administrative provisions to respond to the pandemic. Nevertheless, the cross-sectoral impact of the initial combat was intense and is potentially long-lasting. The country could have further benefited from evidence-based policy and planning attuned to local needs and vulnerabilities. Experience from India offers insights to nations, especially LMICs, on the need to have contextualised pandemic response plans.

Rare-earth ions (REIs) have incomplete 4f shells and possess narrow optical intra-4f transitions due to shielding from electrons in the 5s and 5p orbitals, making them good candidates for solid-state optical quantum memory. The emission of Er3+ in the telecom C-band (1530 nm–1565 nm) makes it especially attractive for this application. In order to build practical, scalable devices, the REI needs to be embedded in a non-interacting host material, preferably one that can be integrated with silicon. In this paper, we show that Er3+ can be isovalently incorporated into epitaxial Y2O3 thin films on Si (111). We report on the synthesis of epitaxial, single-crystalline Er:Y2O3 on Si with a narrow inhomogeneous linewidth in the photoluminescence (PL) spectra, 5.1 GHz (

Chronic abdominal pain is a common reason for medical consultation. During evaluation the focus often remains on visceral causes, ignoring the possibility of abdominal wall as the pain generator. Abdominal wall pain secondary to anterior cutaneous nerve entrapment syndrome is not infrequent. However, the awareness about the condition is low and specific diagnostic tests for its diagnosis are lacking. Good communication with the patient, high degree of suspicion, and comprehensive clinical examination are keys to establish the diagnosis. The case report highlights the importance of ultrasound-guided superficial nerve blocks in confirming the diagnosis of such cases.

Autophagy is a physiological degradation process that removes unnecessary or dysfunctional components of cells. It is important for normal cellular homeostasis and as a response to a variety of stresses, such as nutrient deprivation. Defects in autophagy have been linked to numerous human diseases, including cancers. Cancer cells require autophagy to migrate and to invade. Here, we study the intracellular topology of this interplay between autophagy and cell migration by an interdisciplinary live imaging approach which combines micro-patterning techniques and an autophagy reporter (RFP-GFP-LC3) to monitor over time, during directed migration, the back–front spatial distribution of LC3-positive compartments (autophagosomes and autolysosomes). Moreover, by exploiting a genetically controlled cell model, we assessed the impact of transformation by the Ras oncogene, one of the most frequently mutated genes in human cancers, which is known to increase both cell motility and basal autophagy. Static cells displayed an isotropic distribution of autophagy LC3-positive compartments. Directed migration globally increased autophagy and polarized both autophagosomes and autolysosomes at the front of the nucleus of migrating cells. In Ras-transformed cells, the front polarization of LC3 compartments was much less organized, spatially and temporally, as compared to normal cells. This might be a consequence of altered lysosome positioning. In conclusion, this work reveals that autophagy organelles are polarized toward the cell front during migration and that their spatial-temporal dynamics are altered in motile cancer cells that express an oncogenic Ras protein.

Au–Cu alloy nanostructures have been synthesized in aqueous phase through co-reduction of HAuCl _4 .3H _2 O and CuCl _2 .2H _2 O by glucose in presence of hexadecylamine at ∼80 °C. By changing the synthesis conditions, nanostructures of various shapes such as nanowires, multiply twinned tripod, tetrapod, etc were observed. Systematic variation of the synthesis condition not only leads to change in size and particle morphology but also develops various other crystallographic characters in the nanoparticles. Alloying behavior of Au–Cu has been examined through transmission electron microscope operating in its conventional and analytical modes coupled with high resolution phase contrast microscopy. These results suggested that nanostructures are composed of homogeneous Au–Cu alloy. Preferential attachment along {111} and {100} crystallographic facets of Au–Cu alloy nanoparticles led to the formation of nanowires. Multiply twinned branched shape Au–Cu (width of branch ∼30 nm) nanostructures exhibit localized surface plasmon resonance maxima in the near-infrared region. The branched shape Au–Cu alloy nanostructures display better surface enhanced Raman scattering response in the detection of methylene blue as compared to spherical Au nanoparticles.

Introduction: Assenting diagnosis of Visceral Leishmaniasis (VL) relies on the detection of Leishmania donovani (L. donovani) in splenic and bone marrow specimens obtained by invasive techniques. Thus, the development of inexpensive, non-invasive serological test encompassing high specificity, sensitivity and diagnostic efficacy is urgently needed. Aim: To assess the significance of recombinant proteins possessing B-cell epitopes in VL diagnosis. Materials and Methods: Employing immunoinformatics approach, the B-cell epitope footprint of L. donovani hypothetical proteins (derived from earlier studies) were decrypted holding good antigenic character with numerous epitopes. L. donovani hypothetical proteins XP_003860226.1 and XP_003861271.1 were first time cloned as His-tagged fusion proteins and purified as novel recombinant protein antigens, designated rLdhyb and rLdhyc respectively. Sanger sequencing method was exploited to sequence gene insert (GeneBank accession number MH479406). Results: B-cell epitopes revealed 100% conservancy with L. infantum. Immunoinformatics data revealed no significant sequence similarity with homo sapien and the causative agent of other diseases like tuberculosis, typhoid, malaria etc., resembling in symptoms to VL. Sequencing chromatogram of cloned gene Ldhyb and Ldhyc revealed 98% and 94% identity with L. donovani. ELISA revealed the absolute specificity with sensitivity of 95.4% for rLdhyb and 91% for rLdhyc. Area under curve for rLdhyb, rLdhyc and SLA were 0.99, 0.99 and 0.961, with standard error 0.002, 0.007 and 0.019 respectively. The in silico data was coherently supported by in vitro result. Conclusion: Absolute specificity, high sensitivity and diagnostic efficacy (rLdhyb: 98%; rLdhyc: 97%) advocated their excellent biomarker property. The present findings provide some basic insights for the future development of novel hypothetical proteins based non-invasive diagnostic tool for VL detection.

The two Ral GTPases, RalA and RalB, have crucial roles downstream Ras oncoproteins in human cancers; in particular, RalB is involved in invasion and metastasis. However, therapies targeting Ral signalling are not available yet. By a novel optogenetic approach, we found that light-controlled activation of Ral at plasma-membrane promotes the recruitment of the Wave Regulatory Complex (WRC) via its effector exocyst, with consequent induction of protrusions and invasion. We show that active Ras signals to RalB via two RalGEFs (Guanine nucleotide Exchange Factors), RGL1 and RGL2, to foster invasiveness; RalB contribution appears to be more important than that of MAPK and PI3K pathways. Moreover, on the clinical side, we uncovered a potential role of RalB in human breast cancers by determining that RalB expression at protein level increases in a manner consistent with progression toward metastasis. This work highlights the Ras-RGL1/2-RalB-exocyst-WRC axis as appealing target for novel anticancer strategies.

Background: Myelodysplastic syndrome (MDS) is a heterogeneous disorder characterized clinically by presence of cytopenia/s. Limited data is available pertaining to the morphological spectrum and cytogenetic profile of Indian MDS patients. The aim of the study was to ascertain the clinco pathological, morphological and cytogenetic spectrum of Indian MDS patients. Material and methods: A retrospective analysis of all patients diagnosed as MDS from June 2012-December 2016 was performed. Their clinical and laboratory data was collated and reviewed. Results: A total of 150 patients of as primary MDS were evaluated with M: F ratio of 1.6:1 and median age of 55.5 years. 64% patients presented with pancytopenia, with thrombocytopenia alone was seen in only 2 cases. There were 66 (44%) cases of MDS-MLD, 33 (22%) MDS-EB 2, 32 (21.3%) MDS–EB 1, 13 (8.6%) cases MDS-SLD and two cases each of MDS-SLD-RS, MDS-MLD-RS and RCC. Cytogenetic data was available in 86/150 patients, 50% of which were abnormal. Complex karyotype was observed to be the commonest abnormality (27.5%). Novel translocations like t(9;22)(q11.2;q34.2) in addition to other abnormalities (n=3), t(2;4)(p25;q23),t(1;5)(p22;q33), t(1;12)(p34;p11.2) and t(5;7;9;)(q13;q32;p22) were observed. Conclusion: The median age of patients in India is almost a decade younger than the western population. Moreover, majority of the patients belonged to the high risk IPSS-R prognostic group (31.4%), followed by intermediate (29%) and very high risk groups (24.4%) in our cohort of patients. Seventy percent individuals, < 40 years belonged to the high prognostic categories, indicating that Indian MDS patients have high disease burden and in turn more likelihood for leukemic transformation.

The unreliability of most of the existing antibody-based diagnostic kits to discriminate between active and treated VL cases, relapse situation and reinfection are a major hurdle in controlling the cases of Kala-azar in an endemic area. An antigen targeted diagnostic approaches can be an attractive strategy to overcome these problems. Hence, this study was focused on identifying the Leishmania antigens, lies in circulating immune complex (CICs), can be used for diagnostic as well as prognostic purposes. The present study was conducted on peripheral blood samples of 115 human subjects, based on isolation of CICs. The SDS-PAGE patterns showed an up-regulated expression of 55 kDa and 23 kDa fractions in an antigens obtained from CICs of all clinical and parasitologically proven untreated visceral leishmaniasis patients before treatment (VL-BT), which ensured absolute sensitivity. However, light expressions of these bands were observed in some VL treated cases. To ascertain the prognostic value, 2D expression profiles of circulating antigens were carried out, which revealed 3 upregulated and 12 induced immunoreactive spots. Out of these, ten prominent spots were excised and subjected for enzymatic digestion to generate peptides. Mass spectrometry (MS) analysis successfully explored 20 peptides derived from kinase, kinesin, acetyl Co-A carboxylase, dynein heavy chains (cytoplasmic and axonemal/flagellar), 60S ribosomal protein, nucleoporin protein, RNA polymeraseII, protease gp63, tubulin, DNA polymerase epsilon subunit, GTP-binding protein and tyrosyl-methionyl t-RNA synthetase-like protein and 19 hypothetical protein of unknown function. Presence of L. donovani proteins in circulating antigens were further validated using anti-Ld actin and anti-α tubulin antibody. Besides, MS derived peptides confirmed its reactivity with patients' sera. Therefore, these shortlisted potential antigens can be explored as antigen-based diagnostic as well as prognostic kit.

Introduction: The HIV pandemic had a prevalence of 0.27% with 20.9 lakhs PLHIV in the year 2011.Decreased CD4 counts and associated opportunistic infections affects their Quality of Life. Objective: The objective of the study was to assess the association between CD4 counts and Quality of Life (QOL). Material and Methods: A cross-sectional study was conducted among 558 subjects visiting ART centre of Burdwan Medical College aged ≥ 15 years.
