Objective: Graft-versus-host disease (GvHD) is a common and serious complication following allogeneic hematopoietic stem cell transplantation (allo-HSCT), significantly impacting transplant efficacy. In the treatment of GvHD, numerous therapeutic approaches have been explored, with mesenchymal stem cells (MSCs) emerging as a prominent immunomodulatory option. We aimed to evaluate efficacy and outcomes of using MSCs for steroid refractory acute GVHD (SR-aGvHD) management.

This study evaluates the protective effects of sinapic acid (SA), a polyphenolic compound with diverse biological activities, against ethanol-induced gastric ulcers in rats. A gastric ulcer model was established using ethanol (ETH), and the experimental groups received either omeprazole (OMEP, 20 mg/kg) or SA at doses of 20 mg/kg and 40 mg/kg via oral gavage for 14 days. Biochemical markers, including total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), malondialdehyde (MDA), and myeloperoxidase (MPO) activity, were assessed alongside proinflammatory cytokines (tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), and IL-6) using ELISA.

Central adrenal insufficiency (CAI) occurs due to a pituitary gland disorder (secondary AI) or hypothalamic dysfunction (tertiary AI). It is a potentially life-threatening condition that has many congenital and acquired causes. Adrenocorticotropic hormone (ACTH) deficiency may be isolated or more commonly it can be accompanied by other pituitary hormone deficiencies or midline defects.

Although glycosidic bonds in purines typically involve the N9 position, the chemical synthesis of adenosine produces N7-ribofuranosyladenine (7A) as a kinetically favorable ribosylation product. Similarly, in the synthesis of LNA-adenosine (AL), a minor product, N7-LNA-adenosine (7AL), is observed. While extensive research has focused on investigating the properties of N9-regioisomers of adenosine, 7A has been largely overlooked and considered as a side-product.

Unlabelled: Phenylalanine (PA) levels below 360 µmol/L do not require treatment; however, cognitive deficits have been observed in patients with elevated PA levels, necessitating a safe upper limit for treatment and therapeutic objectives. The main purpose of this study is to evaluate the correlation between developmental assessments (Denver Developmental Screening Test-II [DDST-II] and Ankara Developmental Screening Inventory [ADSI]) and electroencephalogram (EEG) findings with blood PA levels and genotypic data in non-phenylketonuria mild Hyperphenylalaninemia (HPA) patients, to re-evaluate their treatment status based on potential adverse outcomes. This study encompassed 40 patients aged 1-5 years diagnosed with HPA and not on treatment, identified through initial blood PA levels, and monitored for a minimum of 1 year on an unrestricted diet.

Objective: Vitamin D deficiency is common in adult patients undergoing allogenic hematopoietic stem cell transplantation (allo-HSCT). Since vitamin D is an important regulatory factor for the immune system, vitamin D deficiency may have effects on antitumor activity, relapse rates, graft versus host disease (GVHD) occurrence and infection rates in allo-HSCT. We aimed to investigate the effects of vitamin D levels on the outcome of allo-HSCT.

Objectives: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a potentially curative treatment for hematological diseases, with success rates improving due to advancements in conditioning regimens and new anti-graft versus host disease (GVHD) drugs. Ruxolitinib, an oral selective Janus kinase (JAK) 1 and 2 inhibitor has been used to mitigate the effects of various inflammatory and myeloproliferative syndromes, given the JAK kinase pathway's central role in cytokine signaling during inflammatory and immune processes. In this study we aimed to assess ruxolitinib's efficacy in patients with chronic GVHD (cGVHD).
