Evaluation of Tryptophan and Its Metabolites in Predicting Disease Activation in Inflammatory Bowel Disease.

: Inflammatory bowel disease (IBD), which comprises ulcerative colitis (UC) and Crohn's disease (CD), is characterized by chronic inflammation and fluctuating disease activity. This study aimed to evaluate serum tryptophan (TRP) and its metabolites as potential biomarkers for predicting disease activation in comparison to fecal calprotectin (FC). : This prospective study included 115 patients (77 with UC and 38 with CD).

Effects of repeated doses of paracetamol administration during pregnancy on lung, kidney, and liver tissues of pregnant rats.

Objectives: Paracetamol is one of the most widely used analgesics and antipyretics in the world. It is the most commonly used analgesic and antipyretic agent in pregnancy. Paracetamol is known to have toxic effects on the liver, lung, and kidney.

Is Bioavailable Vitamin D Better Than Total Vitamin D to Evaluate Vitamin D Status in Obese Children?

Introduction: Free hormones are biologically more active in target tissues. Thus, measurement of vitamin D taking into account bioavailability and free vitamin D may be preferable, especially when evidence is contradictory, as in obese children. In order to assess bioavailablity and free vitamin D, using a previously reported formula, vitamin D-binding protein (VDBP) level was measured and VDBP polymorphisms were also evaluated because of variations in binding affinity.

Protective Effects of Contractubex® on Stricture Formation after Experimental Corrosive Esophageal Burns in Rats.

Aim/background: Although many agents have been tested as treatment options for caustic esophageal burn (CEB), none have successfully suppressed the formation of strictures. Thus,the purpose of this study was to determine the efficacy of Contractubex® gel (10% onion extract, 50 U/gr heparin, and 1% allantoin) in stricture preventing after CEB.

Methods: In this study, 24 Wistar-albino rats were divided into 4 groups.

Ziziphus jujube ameliorated cavernosal oxidative stress and fibrotic processes in cavernous nerve injury-induced erectile dysfunction in a rat model.

The aim of this study was to investigate potential antioxidant and antifibrotic effects of Ziziphus jujube (ZJ) in a cavernosal nerve injury (CNI)-induced erectile dysfunction (ED) rat model. Forty-eight male rats were assigned to six-sized groups as group 1: sham-operated; group 2: sham-operated + low-dose ZJ (200 mg/kg); group 3: sham-operated + high-dose ZJ (400 mg/kg); group 4: CNI + distilled water; group 5: CNI + low-dose ZJ; and group 6: CNI + high-dose ZJ. At the end of 2 weeks, intracardiac blood was taken and rats were sacrificed.
