Hepatocellular carcinoma (HCC) is one of the most aggressive cancer types. MicroRNAs (miRNAs) are small noncoding regulatory RNAs that function posttranscriptionally. miRNA deregulation was observed in the development and progression of HCC. In this study, we aimed to investigate the expression levels of four miRNAs (mir-33a, mir-203b, mir361-3p, and mir-424) in HCC patients in comparison to healthy individuals. ⋯ Our results indicated that mir-33a, mir-203b, and mir-361-3p may significantly contribute to tumor pathogenesis in HCC and have potential to be used as a noninvasive biomarker for cancer therapy.

Sleep disorders and frailty increase with advancing age, along with physical disabilities, cognitive dysfunction, mood disorders, and social vulnerability. Thus, the study objective was to evaluate the relationship between frailty and sleep quality in the oldest old patients. ⋯ Sleep quality was significantly decreased in the oldest old frail patients compared to the nonfrail ones, and poor sleep quality was independently associated with frailty. Evaluating the sleep patterns of the oldest old patients with CGA in daily geriatric practice might help to improve the quality of life of frail patients.

Sphincter-preserving surgery is one of the main goals in the treatment of rectal cancer because it improves the quality of life (QoL). However, some patients may experience disrupted symptoms called anterior or low anterior resection syndrome (LARS). This study was designed to evaluate the frequency and influencing factors of LARS in patients who underwent sigmoid or rectal resection. ⋯ LARS may frequently occur in patients who have undergone rectal resection. In this study, the most important factors influencing LARS were found to be the proximity of anastomosis to the anal canal and creating a protective stoma. Receiving chemoradiotherapy also plays an important role in LARS.

Dipeptidyl peptidase-4 (DPP4) inhibitors, a class of oral antidiabetic drugs, have been shown to be protective on the vascular system because of their antiinflammatory, antiatherosclerotic, and vasodilatory effects. ß2-adrenoceptors (ß2-ARs) mediate the vasorelaxation in the aorta. However, ß3-adrenoceptor-mediated relaxation has not been studied in diabetic aorta yet. Thus, we aimed to study the effect of sitagliptin treatment on ß2- and ß3-adrenoceptor-mediated relaxations in the diabetic rat aorta. ⋯ Our results indicate that sitagliptin treatment does not alter ß-AR-mediated relaxation in streptozotocin-diabetic rat aorta; however, it significantly stimulates the eNOS pathway. Future studies are needed to clarify the relationship between the eNOS pathway and DPP-4 inhibition.

Vestibular rehabilitation has an important role in the reduction of symptoms and in the recovery of patients in peripheral vestibular pathologies. Objective and subjective vestibular assessment tools are needed to assess vestibular rehabilitation effectiveness. The aims of the study were to develop the Turkish version of the internationally used Vestibular Rehabilitation Benefit Questionnaire (VRBQ) measure and to demonstrate the reliability and validity properties of the Turkish version in patients with peripheral vestibular hypofunction (PVH). ⋯ The results suggest that the Turkish version of the VRBQ is reliable and valid for evaluating the vestibular rehabilitation results.
