Room-temperature response of MOF-derived Pd@PdO core shell/γ-FeO microcubes decorated graphitic carbon based ultrasensitive and highly selective H gas sensor.

With the current upsurge in hydrogen economies all over the world, an increased demand for improved chemiresistive H sensors that are highly responsive and fast acting when exposed to gases is expected. Owing to safety concerns about explosive and highly flammable H gas, it is important to develop resistive sensors that can detect the leakage of H gas swiftly and selectively. Currently, interest in metal-organic frameworks (MOFs) for gas-sensor applications is increasing due to their open-metal sites, large surface area, and unique surface morphologies.

Interconnected Vanadyl Pyrophosphate Nanonetworks as a Flexible Electrode for High-Voltage and Long-Life Li-Ion Supercapacitors.

Engineering vanadium-based materials with high conductivity, superior redox performance, and high operating voltage has attracted widespread attention in energy storage devices. Herein, we demonstrated a simple and feasible phosphorization technique to design three-dimensional (3D) network-like vanadyl pyrophosphate ((VO)PO) nanowires on flexible carbon cloth (CC) (VP-CC). The phosphorization process enabled the VP-CC to increase the electronic conductivity, and the interconnected nano-network of VP-CC opens pathways for fast charge storage during the energy storage processes.

Performance comparison of distinct bismuth molybdate single phases for asymmetric supercapacitor applications.

The enticing features of metal molybdates make them an attractive candidate for energy storage systems. This report describes the synthesis of three distinct single-phase bismuth molybdates (BiMoO; α-BiMoO, β-BiMoO, and γ-BiMoO) using the gel matrix particle growth method and their application in high-performance asymmetric supercapacitors. The single phase and purity of the synthesized BiMoO particles were confirmed by X-ray diffraction (XRD) and further verified by Raman analysis.

Ternary ZnNiSe nanostructures as efficient photocatalysts for detoxification of hazardous Congo red, methyl orange, and chrome yellow dyes in wastewater sources.

Water contamination by hazardous organic pollutants poses an extreme threat to the environment and globally endangers aquatic life and human health. Hence, the removal of toxic organic effluents from water sources is necessary to ensure a healthy green environment. To this end, a new class of emerging, visible-light-driven Zn- and Ni-based ternary metal-selenide (ZnNiSe) nanophotocatalysts, with tunable nanostructures via regulation of the stoichiometric ratios of Zn and Ni, were synthesized for efficient water purification by a facile one-pot hydrothermal process.

Evaluation of Serum Ferritin as a Prognostic Marker in Acute Hemorrhagic Stroke.

 Acute hemorrhagic stroke (AHS) resulting from intracerebral hemorrhage (ICH) is a rampant neurological disorder with devastating consequences, particularly in Indians. Recently, serum ferritin levels have been related to adverse cardiovascular and stroke outcomes. We aimed to evaluate the prognostic utility of serum ferritin in AHS.

Evaluation of Leptin as a Marker of Insulin Resistance in Type 2 Diabetes Mellitus.

Background: Type 2 diabetes mellitus (T2DM) is a leading cause of mortality and morbidity worldwide, whose incidence is rapidly increasing in India. T2DM is caused by varying degrees of insulin resistance (IR) and relative insulin deficiency. Leptin, an adipokine with the primary function of regulating energy balance, is found to mediate insulin secretion and sensitivity in peripheral tissues.

Exceptionally Active and Stable Spinel Nickel Manganese Oxide Electrocatalysts for Urea Oxidation Reaction.

Spinel nickel manganese oxides, widely used materials in the lithium ion battery high voltage cathode, were studied in urea oxidation catalysis. NiMn2O4, Ni1.5Mn1.

Polyarthritis and massive small bowel bleed: An unusual combination in scrub typhus.

Scrub typhus is an acute febrile illness caused by the intracellular parasite Orientia tsutsugamushi. Although most cases present with mild symptoms and signs and recover spontaneously, some cases can be severe with multi-organ dysfunction and a protracted course, which may be fatal if left untreated. Apart from fever and constitutional symptoms, atypical presentations allow this disease to mimic several common conditions.

Miliary tuberculosis with left brachial monoplegia: A case report.

Tuberculoma of the brain is a major neurological problem in developing countries accounting for 12 to 30 per cent of all intracranial masses. It often presents with focal neurological symptoms or seizures. Simultaneous occurrence of brain tuberculoma with miliary mottling in the lungs is uncommon in the immunocompetent patient.

Reversible lower limb deep vein thrombosis following haemotoxic snakebite-a case report.

Haemotoxic snakebite, presenting with coagulopathy and bleeding manifestations, is quite common. Thrombotic manifestations are infrequently observed. We describe the unusual case of a young male who developed deep vein thrombosis (DVT) of the left lower limb following snakebite, despite an ongoing coagulopathy.

Typhoid fever with caecal ulcer bleed: managed conservatively.

Typhoid fever is caused by enteroinvasive Gram-negative organism Salmonella typhi. The well-known complications of typhoid fever are intestinal haemorrhage and perforation. In the pre-antibiotic era, these complications were quite common, but in the current antibiotic era the incidence of these complications is on the decline.
