Regional Trends and Spatial Gradients of Total Column Methane over India, China, and USA─Implications for Emissions from Coal Mining and Oil/Gas Exploitation.

Observation-based verification of regional/national methane (CH) emission trends is crucial for transparent monitoring and mitigation strategy planning. Although surface observations track the global and sub-hemispheric emission trends well, their sparse spatial coverage limits our ability to assess regional trends. Dense satellite observations complement surface observations, offering a valuable means to validate emission trends, especially in regions where emissions changes are substantial but debated.

Novel Inherited N-terminus TAP1 Variants and Severe Clinical Manifestations- Are Genotype-Phenotype Correlations Emerging?

Major histocompatibility complex class I deficiency results from deleterious biallelic variants in TAP1, TAP2, TAPBP, and B2M genes. Only a few patients with variant-curated TAP1 deficiency (TAP1D) have been reported in the literature and the clinical phenotype has been variable with an emphasis on autoimmune and inflammatory complications. We report TAP1D in a Nepalese girl with a severe clinical phenotype with serious viral infections at a very young age.

The NLRP3 inflammasome: A central player in multiple sclerosis.

Multiple sclerosis (MS) is a neurological autoimmune condition associated with many symptoms including spasticity, pain, limb numbness and weakness. It is characterised by inflammatory demyelination and axonal degeneration of the brain and spinal cord. A range of disease-modifying therapies (DMTs) are available to suppress inflammatory disease activity in MS, however, there is a pressing need for new therapeutic avenues as DMTs have a limited ability to suppress confirmed disability progression.

Benchmarking DFT approximations for studying apatites.

Despite the growing interest in apatites, available experimental studies on their properties are limited in scope. Researchers, therefore, are increasingly resorting to predictions using density functional theory (DFT). However, large deviations can be seen between DFT-based estimates and experimental results, presumably due to approximations made in DFT models.

Flash chromatographic isolation of garcinol and isogarcinol from Garcinia indica Choisy (kokum) fruit and evaluation of their potential antibiofilm activity.

The present study describes the isolation and separation of isogarcinol and garcinol from kokum fruit by flash chromatography using water (containing 0.1 % formic acid) and methanol mixed with acetonitrile (1:1) with UV detection at 254 nm and was characterised by HR-MS and NMR studies. These were further subjected to antimicrobial studies on Staphylococcus aureus FR1722 and Listeria monocytogenes Scott A by agar diffusion assay and broth microdilution method wherein the MIC (Minimum Inhibitory Concentration) of garcinol and isogarcinol were, 20 μg/mL and 50 μg/mL for S.
