THE EFFECT OF CARBON MONOXIDE RELEASING MOLECULE-2 ON HEALING OF ISCHEMIC COLON ANASTOMOSIS IN RATS.
Ischemia on the colon wall negatively affects healing of anastomosis. We were aimed to evaluate the effects of carbon monoxide releasing molecule-2 (CORM-2) on the healing of anastomosis in a rat model of the ischemic colon. ⋯ In ischemic colon anastomosis, reduces cell destruction by suppressing the oxidative reaction, and strengthening the antioxidative mechanisms of the cells. It also increases collagen formation, epithelial development, and neoangiogenesis.

Physical exercise is a state of physiological stress that requires adaptation of the organism to physical activity. Glycogen is an important and essential energy source for muscle contraction. Skeletal muscle and liver are two important glycogen stores, and the energy required to maintain exercise in rodents are provided by destruction of this glycogen depot. In this study, the effects of endogenous opioid peptide antagonism at the central nervous system level on tissue glycogen content after exhaustive exercise were investigated. ⋯ Our findings indicate that icv administered opioid peptide antagonists may play a role in glycogen metabolism in peripheral tissues such as skeletal muscle, heart, and liver.

We aimed to evaluate the efficacy of fulvestrant and affecting clinical factors, including the optimal sequencing of fulvestrant and chemotherapy in a real-life cohort. ⋯ In our experience, fulvestrant treatment was associated with comparable OS to clinical trials in a large cohort of patients. Patients treated with fulvestrant before chemotherapy were garnered significantly more benefit.

The aim of this study is to determine the mutation spectrums and clinical characteristics of NF1 patients followed up in our center and to investigate whether there is a genotype-phenotype relationship. ⋯ Fifty-three different mutations were found as a result of the NF1 gene analysis studied from patients and their family members. Among these 53 mutations, stop codon mutation was the most frequently detected mutations. Sixteen out of 50 (32%) mutations were found to be novel mutations. Twenty-eight tumors developed in our patients. Twenty of them were optic gliomas and others were medullary thyroid carcinoma, glioblastome multiforme, pons glioma, acute lymphoblastic leukemia, pilocytic astrositoma, hypothalamic glioma, cerebral hamartoma and cardiac fibroma. No genotype-phenotype relationship was detected in patients Conclusion: Comprehensive mutation analysis of NF1 will increase our knowledge due to its different phenotypic characteristics even in the same mutation.

Effective therapeutic approaches for SARS-CoV-2 pandemic are urgently needed. Hydroxychloroquine (HCQ) alone or in combination with azithromycin has been used in several countries, without any clear evidence. This study aimed to determine the effectiveness and safety of hydroxychloroquine as compared to hydroxychloroquine and azithromycin combination in patients with COVID-19 pneumonia. ⋯ The present findings suggest that adding azithromycin to HCQ is not associated with any improvement in clinical outcome and mortality in patients with COVID-19 pneumonia and supports the current knowledge not to include azithromycin in the initial treatment of COVID-19.
