The current study was aimed to investigate the effect of rifampicin (Rif), a stimulator of P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP), on limiting the passage of AFB1 (Aflatoxin B1) into testicular tissue. The second objective was to examine the potential protective effects of Boswellia serrata extract (BSE), which exhibits a strong antioxidant capacity, alone or incombination with Rif against testicular damage induced by AFB1. A total of 49 male Sprague-Dawley rats were randomly divided into seven experimental groups as follows: control (placebo), Rif (10 mg/kg), BSE (500 mg/kg), AFB1 (0.

Background: Modulation of protein synthesis according to the physiological cues is maintained through tight control of Eukaryotic Elongation Factor 2 (eEF2), whose unique translocase activity is essential for cell viability. Phosphorylation of eEF2 at its Thr56 residue inactivates this function in translation. In our previous study we reported a novel mode of post-translational modification that promotes higher efficiency in T56 phosphorylation.

As novel promising anticancer candidates, the piano-stool type complexes of ruthenium, [RuCl(η-p-cymene)(N,S-L)]PF, K-, were synthesized from the reaction of the substituted benzo[b]thiophene based thiosemicarbazone ligands (L) with [{RuCl(η-p-cymene)}(μ-Cl)]. All complexes were fully characterized using elemental analysis, and spectroscopic methods such as FT-IR and H NMR. The molecular masses of the complexes were proved by MALDI-TOF analysis.

Understanding the pharmacodynamics of ritonavir through metabolomics offers insights into its side effects and helps in the development of safer therapies. This study aimed to investigate the effects of ritonavir treatment on the metabolic profiles of rabbits via a metabolomics approach, with the objective of elucidating its impact on various biochemical pathways and identifying relevant biomarkers. The rabbits were divided into control and ritonavir-treated groups, and their plasma samples were analyzed via ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF/MS/MS).

This study evaluates the nutritional value and health risks of fish from Miliç Wetland, Türkiye, focusing on potentially toxic elements (PTEs) in Esox lucius, Squalius cephalus, and Carassius gibelio. Using ICP-MS, mean PTE concentrations were determined, including Zn (4979 μg/kg), Fe (4241 μg/kg), and As (125 μg/kg). Macro elements like K, P, and Ca were also assessed for nutritional profiling.

Rationale: Ketamine, a non-competitive NMDA receptor antagonist, produces antidepressant effects at subanesthetic doses. The therapeutic effect, however, is often accompanied by cognitive side effects, including memory impairments. Yet, the specific effects of ketamine on different processes of implicit and explicit memory remain to be elucidated.

Introduction: Contraceptive care is an opportunity for providers to help clients achieve their reproductive health goals. Client-centeredness is a core element of quality care; however, evidence suggests that the provision of client-centered contraceptive counseling needs improvement. This systematic review summarizes recent evidence on client preferences related to contraceptive care, including how client-centered approaches inform outcomes.

  • Stigma in multiple sclerosis (MS) leads to negative outcomes such as anxiety, depression, and social isolation, although there's currently no specific scale to measure it.
  • The study aimed to create and validate a "Multiple Sclerosis Stigma Scale (MSSS)" through a three-phase methodological approach, which included defining stigma, generating items, and testing the scale's psychometric properties.
  • The final 12-item MSSS showed strong reliability and validity in assessing stigma, revealing two main factors: discrimination and disclosure, making it suitable for use with Turkish MS patients.

Aim: To investigate tomographic features of late corneal ectasia after keratoplasty for keratoconus and compare penetrating keratoplasty (PK) and deep anterior lamellar keratoplasty (DALK) in terms of incidence, time of onset and risk factors of corneal ectasia.

Methods: Sixty eyes with PK and 30 eyes with DALK operated between 1999 and 2021 were analyzed. Final Pentacam scans were evaluated together with vision and previous topographies.

Article Synopsis
  • This study focuses on 17α Hydroxylase/17,20 Lyase Deficiency (17OHD), a rare form of adrenal hyperplasia, highlighting its clinical features such as delayed puberty and hypertension commonly diagnosed in late adolescence.
  • Researchers analyzed data from 97 cases across the country, revealing that hypertension was present in 65% and hypokalemia in 34% of patients, with a significant number requiring antihypertensive treatment.
  • The findings suggest that early diagnosis can be guided by hypertension and hypokalemia, while the final heights of patients generally fall within normal ranges, though the connection between genetic mutations and clinical outcomes remains unclear.

  • - The study focuses on understanding the reasons behind pregnancy loss after transferring a healthy (euploid) embryo, as such losses are often linked to chromosomal issues, but those aren't the main cause here.
  • - Researchers analyzed pregnancy outcomes from single euploid embryo transfers between January 2017 and March 2020 and found certain factors, like previous pregnancy loss history and embryo quality, that were significantly different between those who experienced total pregnancy loss and those who achieved live births.
  • - Although morphokinetic analysis of embryo development showed no major differences statistically, the group that had pregnancy losses had a higher occurrence of uneven blastomeres during early division, suggesting that evaluating clinical and embryological data could help improve patient outcomes and lead
