Diagnostic tools of metabolic and structural brain disturbances in neonatal non-ketotic hyperglycinemia

WOS: 000309234600024PubMed ID: 23005907Non-ketotic hyperglycinemia (NKH) is a rare autosomal recessive disorder of glycine metabolism. We report a newborn case of NKH and discuss the effects of this rare disease on brain metabolism and structure together with amplitude-integrated electroencephalography, cranial magnetic resonance and magnetic resonance spectroscopy findings which are very rarely reported together so far

All-trans retinoic acid prevents cisplatin-induced nephrotoxicity in rats

The aim of this study is to investigate the effects of all-trans retinoic acid (ATRA) use on cisplatin (CP)-induced nephrotoxicty. Twenty-eight rats were randomly divided into four groups. The rats in the control group were injected a single dose of 1ml/kg saline intra-peritoneally (IP) during 10days. The rats in the ATRA group were injected a single dose of ATRA during 10days. The rats in the ATRA+CP group were injected a single dose of CP on the fourth day of the 10days of ATRA treatment. The rats in the CP group were injected a single dose of CP on the fourth day of 10days without administering a treatment. After treatment, the groups were compared with regard to total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) levels in renal tissue and renal histopathology. The serum creatinine and urea values were statistically significantly higher in the CP group compared to the other groups. The serum creatinine and urea values were statistically significantly lower in the ATRA+CP group when compared to the CP group. Although the TOS and OSI levels were found to be lower in the ATRA+CP group compared to the CP group, the difference was not statistically significant. Administration of ATRA together with CP was observed to reduce the histopathologic destruction in the kidney and lead to mild tubular degeneration, vacuolization, and necrosis (57.1% grade 1; 28.6% grade2, and 14.3% grade 3 necrosis). The results of the present study have revealed that ATRA administration ameliorates CP-induced nephrotoxicity; however, further studies are required to identify this issue before clinical application

Protective Effect of All-Trans Retinoic Acid in Cisplatin-Induced Testicular Damage in Rats

Purpose: To investigate the effects of all-trans retinoic acid (ATRA) in cisplatin (CP)-induced testicular damage in rats. Materials and Methods: Twenty-eight male Wistar rats were divided into four groups: Control, ATRA alone, ATRA+CP, and CP alone. Body weight, testicular weight, sperm count, sperm motility, percentage of abnormal sperm, total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI) in testicular tissue, and testicular histopathology were compared among groups. Results: The sperm count and motility significantly decreased and the percentage of abnormal sperm significantly increased in the CP group compared to the control and ATRA groups. CP+ATRA administration significantly increased the sperm count and motility, but reduced the abnormal sperm count. CP administration significantly increased TOS and OSI compared to the control group and the other groups. Administering CP+ATRA significantly decreased TOS and the OSI in testicular tissue and reduced spermatogenesis, but increased the Johnsen score. Conclusions: The destructive effects of CP treatment on testicular tissue and spermatogenesis were reduced by administering ATRA

Utilization of biological variation data in the interpretation of laboratory test results - survey about clinicians' opinion and knowledge.

Introduction: To interpret test results correctly, understanding of the variations that affect test results is essential. The aim of this study is: 1) to evaluate the clinicians' knowledge and opinion concerning biological variation (BV), and 2) to investigate if clinicians use BV in the interpretation of test results
