Protein lysine crotonylation has been found to be closely related to the occurrence and development of various diseases. Currently, site identification of crotonylation is mainly dependent on antibody enrichment; however, due to the cost, heterogeneity, and specificity of antibodies, it is desired to develop an alternative chemical tool to detect crotonylation. Herein, we report an alkynyl-functionalized bioorthogonal chemical probe, Cr-alkyne, for the detection and identification of protein lysine crotonylation in mammalian cells.

Detection of spp. DNA in gynaecological samples by quantitative real-time polymerase chain reaction (qPCR) is considered to be the reference diagnostic test for female genital schistosomiasis (FGS). However, qPCR needs expensive laboratory procedures and highly trained technicians.

Background And Aim: A healthy diet has been recommended for non-alcoholic fatty liver disease (NAFLD). We aim to investigate the associations of diet quality indices with the risk of developingmetabolic-associated fatty liver disease (MAFLD).
Methods: We conducted this nested case-control study by recruiting 968 cases with MAFLD and 964 controls from the participants of the baseline phase of the Sabzevar Persian Cohort Study (SPCS).

Reticulocyte Binding Protein Homologue (RH5), a leading malaria vaccine candidate, is essential for erythrocyte invasion by the parasite, interacting with the human host receptor, basigin. RH5 has a small number of polymorphisms relative to other blood-stage antigens, and studies have shown that vaccine-induced antibodies raised against RH5 are strain-transcending, however most studies investigating RH5 diversity have been done in Africa. Understanding the genetic diversity and evolution of malaria antigens in other regions is important for their validation as vaccine candidates.

Ferroptosis is linked to various tumor biological traits, and alternative splicing (AS), a crucial step in mRNA processing, plays a role in the post-transcriptional regulation of ferroptosis-related genes (FRGs). A least absolute shrinkage and selection operator (LASSO) penalized Cox regression analysis was utilized to build a prognostic signature based on 12 AS events (p < 0.05), which was validated in gastric cancer (GC) patients.
