Background: Hypothyroidism is a common endocrine disorder with a bi-directional relationship to Chronic Kidney Disease (CKD), presenting a notable complication in CKD patients. This study aimed to explore the impact of hypothyroidism on kidney function in CKD patients.

Materials And Methods: This study included 150 participants, with 110 CKD patients without hypothyroidism and 40 CKD patients with hypothyroidism.

Article Synopsis
  • Protein arginine methyltransferases (PRMTs) are crucial enzymes in eukaryotic cells that modify proteins and influence various biological processes like gene transcription and metabolism.
  • This study uncovered multiple higher-order structures of PRMT1, such as tetramers and octamers, using cryo-electron microscopy and linked these structures to enhanced enzyme activity.
  • Oligomerization was shown to increase PRMT1's efficiency in methylation and suggested that even a non-active mutant of PRMT1 could boost the function of the wild-type enzyme, indicating a new regulatory mechanism in enzyme activity.

Here, we present a protocol for the in vitro phosphorylation of Src kinase domain (SrcKD), preparation of phospho-SrcKD in complex with the D1 domain of rPTP epsilon (rPTPεD1), and binding assays using biolayer interferometry (BLI). We describe steps for the in vitro phosphorylation of SrcKD and preparation of the phospho-SrcKD: rPTPεD1 complex for small-angle X-ray scattering (SAXS) experiments. We then detail instructions for the BLI binding assay to determine the binding affinity between phospho-SrcKD and rPTPεD1.

Background: Malaria has been one of India's most considerable health problems since 1940. The objective of our study is to determine the status of the National Malaria Elimination Programme in India by using epidemiological indicators.

Methods And Materials: The annual reports of malaria for the years 2014-2021 and monthly reports for 2020 and 2021 were collected from the official web portal and were analysed for study specific assessments.

The structure determination of protein tyrosine phosphatase (PTP): phospho-protein complexes, which is essential to understand how specificity is achieved at the amino acid level, remains a significant challenge for protein crystallography and cryoEM due to the transient nature of binding interactions. Using rPTPεD1 and phospho-SrcKD as a model system, we have established an integrative workflow to address this problem, by means of which we generate a protein:phospho-protein complex model using predetermined protein structures, SAXS and pTyr-tailored MD simulations. Our model reveals transient protein-protein interactions between rPTPεD1 and phospho-SrcKD and is supported by three independent experimental validations.

BM212 is a potent anti-TB agent with pharmacophoric features similar to the antidepressant drug sertraline. The shape-based virtual screening of the DrugBank database on BM212 resulted in the identification of several CNS drugs with appreciable Tanimoto scores. The docking simulations also ascertained the selectivity of BM212 towards the serotonin reuptake transporter protein (SERT) with a docking score of -6.

: The role of TLR's in the pathogenesis of dengue is not explored well. Differential expression of TLR2 and TLR4 was reported in dengue cases. In the present study in order to understand the expression pattern of various TLR's, including TLR2, TLR3, TLR4 and TLR9, mRNA levels were determined in various dengue study groups compared to control groups, at the time of admission and around defervescence using quantitative real-time PCR (RT-PCR).

Billions of tons of keratin bio-wastes are generated by poultry industry annually but discarded that result in serious environmental pollution. Keratinase is a broad spectrum protease with the unique ability to degrade keratin, providing an eco-friendly way to convert keratin wastes to valuable amino acids. In this report, a feather-degrading thermophilic bacterium, Meiothermus taiwanensis WR-220, was investigated due to its ability to apparently complete feather decay at 65 °C in two days.

The objective of this study was to investigate the effect of oral administration of antiretroviral drugs (indinavir, ritonavir, atazanavir, efavirenz and nevirapine) on the pharmacodynamics of gliclazide in rats (normal and diabetic) and rabbits with respect to glucose-insulin homeostasis to evaluate the safety and effectiveness of the combinations. Blood samples were collected at regular time intervals in rats from retro orbital puncture and by marginal ear vein puncture in rabbits. All the blood samples were analyzed for blood glucose by glucose oxidase-peroxidase method and insulin by a radio immuno assay method.

Oxidative stress is involved in diabetes mellitus and its complications. Since diabetes is a stress-related disorder, supplementation with antioxidants may improve the condition. The purpose of this study is to know the effect of oral administration of selenium on blood glucose and its influence on gliclazide induced hypoglycaemia/antihyperglycaemia in normal and alloxan-induced diabetic rats.
