Objective: Epicatechin (EC) is one of the major components green tea catechins. This study investigated effect amount epicatechin obtained by brewing under optimal conditions against oxidative stress induced hydrogen peroxide (H2O2). Materials and Methods: In peripheral blood mononuclear cells (PBMCs), determined optimum was applied 250 µM H2O2 cell viability MTT test, total antioxidant status (TAS) oxidant (TOS) were biochemical analysis, apoptosis-related Bax, Bcl2, p53 expression analysis...

Obstructive sleep apnea syndrome (OSAS) is influenced by genetic, environmental, and developmental factors, with hereditary risk estimated at around 40%. Increasing evidence suggests that OSAS a low-grade chronic inflammatory disease, though the exact mechanisms remain unclear. NLRP3, key component of inflammasome, plays central role in initiating inflammation. This study investigated impact potential single nucleotide polymorphisms (SNPs) NLRP3 promoter region on plasma levels OSA-related...

ABSTRACT Vaccines remain a vital public health tool to reduce the burden of COVID-19. COVID-19 vaccines that are more closely matched circulating SARS-CoV-2 lineages elicit potent and relevant immune responses translate improved real-world vaccine effectiveness. The rise in prevalence Omicron JN.1 lineage, subsequent derivative sublineages such as KP.2 KP.3, coincided with reduced neutralizing activity effectiveness XBB.1.5-adapted vaccines. Here, we characterized biophysical immunologic...

Obezite, genetik, çevresel faktörler ve bunların karmaşık
 etkileşimleri tarafından yönetilen birçok kronik
 hastalık ile ilişkilidir. Genetiğin obeziteye yatkınlıkta
 önemli rol oynadığı riskine %70'e kadar
 katkıda bulunabileceği tahmin edilmektedir. Yapılan
 genetik çalışmalar, genlerin bulunduğunu
 doğrulamıştır. Genlerdeki anomaliler, Bardet-
 Biedl Prader-Willi sendromları gibi obezite ile
 ilişkili bozukluklardan doğrudan sorumludur....

Abstract Claudins are central components of tight junctions that regulate epithelial cell barrier function and polarity. Altered claudin expression patterns have been demonstrated in numerous cancer types lineage-specific claudins proposed as therapy targets. The objective this study was to assess 6 (CLDN6) 18 isoform 2 (CLDN18.2) human non-small lung (NSCLC). Transcript levels were evaluated based on gene microarray data from a fresh-frozen NSCLC tissue cohort (n=196). Protein CLDN6...

Bir gastrik peptit olan grelin ve onun büyüme hormonu salgılatıcı G protein-bağlı reseptörünün glukoz metabolizması enerji homeostazında önemli bir rol oynadığına dair ciddi kanıtlar mevcuttur. Bu nedenle, Tip 2 diyabet için duyarlılık alelleri taşıyan bu genler potansiyel birer aday olarak değerlendirilmektedir. Isparta yöresinden 75 hastası 25 kontrolden oluşan 100 Türk yetişkin bireyin dahil edildiği vaka-kontrol kesitsel ilişkilendirme çalışması yapıldı. Grelin geninde dört promotör...
