Although the pathophysiology has not yet been clarified, dopamine and iron metabolism and spinal cord pathologies are blamed for causing the condition. There are few studies on spinal reflex mechanisms on RLS. In the present study, we aimed to investigate the role of presynaptic inhibition (PreI) in the spinal cord in RLS.Methods Fourteen patients with RLS and 14 controls with similar demographic characteristics were included in the study. Soleus muscle H-reflex (Ht) investigation was performed for subjects whose electrophysiologic investigation was normal. The Ht response was conditioned to the stimulation of the common peroneal nerve (CPN) (Hc). The test and conditioned stimulation intervals were kept between 10 ms, 20 ms, 30 ms, 40 ms, 50 ms, 75 ms, 100 ms, 150 ms and 200 ms. In each inter-stimulus interval, nonparametric repeat measurement evaluations were conducted with the percentage value of Hc/Ht. The Hc/Ht values of the study and control groups in the same intervals were compared separately.Results A significant decrease was detected in Hc values in the control group in the repeat measurement values at 20 ms and 100 ms inter-stimulus intervals; however, there was not decrease in any intervals in the patient's group.Conclusion The absence of any decrease in Hc reflexes for 20-100 ms intervals revealed that discernible PreI was vanished in RLS patients.To preserve material for future genetic studies, human B-lymphocytes from whole blood samples are routinely transformed into lymphoblastoid cell lines (LCLs) by in vitro infection with Epstein-Barr virus. To determine the rate and frequency of chromosomal changes during long-term culture, we established 10 LCLs (from eight individuals). Before transformation, these cases showed a normal karyotype (three cases), a small supernumerary marker chromosome (three cases), or an aberrant karyotype (four cases). Chromosome analyses were performed at 8-week intervals over a period of at least 1 year, up to 3 years. Surprisingly, we demonstrate that chromosomal instability is the rule, rather than the exception, during long-term culture of LCLs. The most commonly observed acquired clonal aberration was trisomy 12, which emerged in all cell lines within 21 to 49 weeks after infection. Telomeric fusions indicating telomere shortening were found after ~21 weeks. Selleck Gefitinib After 1 year of cultivation, the proportion of cells with the original karyotype decreased to ≤10% in 7 of the 10 cell lines. To preserve cells with aberrant genomes, we conclude the cultivation time of LCLs must be restricted to the absolute minimum time required.Background Regarded as the most important clinical characteristic of middle ear cholesteatoma, the exact mechanism of bone resorption in cholesteatoma still remains unknown.Objectives To investigate protein expression of PTHrP and RANKL in acquired middle ear cholesteatoma epithelium and analyze their functional roles in the etiopathogenesis of bone resorption in middle ear cholesteatoma.Material and methods A total of 22 patients who underwent surgical treatment for middle ear cholesteatoma were recruited in the study. Protein expression of PTHrP and RANKL in middle ear cholesteatoma and normal postauricular skin was investigated by immunohistochemical staining. Correlations between bone resorption degree and expression of PTHrP and RANKL were also analyzed.Results Protein expression of PTHrP and RANKL in cholesteatoma epithelium significantly increased when compared with normal postauricular skin epithelium. In cholesteatoma epithelium, a significantly positive association was observed between PTHrP and RANKL expression. Meanwhile, obviously positive correlations between protein expression of PTHrP and RANKL and bone resorption degree were discovered.Conclusions and significance The increased protein expression of PTHrP and RANKL in cholesteatoma epithelium, and their associations with the degree of bone resorption, revealing that PTHrP might promote bone resorption process in middle ear cholesteatoma through RANKL signaling pathway.Introduction With the rising prevalence of type 2 diabetes (T2D), there is a substantial interest in novel, glucose-lowering drugs that may complement existing treatment options. Imeglimin is an oral antidiabetic agent currently in clinical development.Areas covered This review is based on a literature search using PubMed and Embase including all published manuscripts and presentations concerning imeglimin. Supplementary information was retrieved from the manufacturer's official webpage. Preclinical and clinical data are summarized with a focus on mechanisms of action as well as clinical efficacy and safety in T2D.Expert opinion Imeglimin's mode of action seems to be improved mitochondrial function in pancreatic beta cells leading to improved insulin secretion and lowering of plasma glucose levels. In clinical trials of up to 24 weeks, imeglimin in doses of 1,000-1,500 mg twice daily conferred modest reductions in glycates hemoglobin A1c of 6-11 mmol/mol (0.5-1.0%) (placebo-adjusted) as a monotherapy and 7 mmol/mol (0.6%) as an add-on therapy to metformin or sitagliptin in patients with T2D. Reported adverse effects were mainly gastrointestinal discomfort. The position of imeglimin among other pharmacotherapies in the treatment of T2D will be determined based on future studies more clearly outlining the safety and long-term cardiovascular effects.Abbreviations AUC area under the curve; BID twice daily; DPP-4 dipeptidyl peptidase 4; GLP-1R glucagon-like peptide-1 receptor; HbA1c glycated hemoglobin A1c; HFHSD high-fat high-sucrose diet; OAD oral antidiabetic; OD once daily; OGTT oral glucose tolerance test; PPAR-γ peroxisome proliferator-activated receptor gamma; PTP permeability transition pore; SGLT-2 sodium-glucose transport protein 2; STZ streptozotocin; T2D type 2 diabetes.Although many studies discussed evidence-based practice among general nurses, few studies were found by the researchers among intensive care unit nurses. Also, no study has been conducted to investigate the predictors of evidence-based practice among intensive care unit nurses in Jordan. Therefore, this study aims to identify the predictors of evidence-based practice among intensive care unit nurses in Jordan. A descriptive cross-sectional design was used to conveniently recruit 132 participants. Self-reported questionnaires were utilized including the Evidence-Based Practice Questionnaire and Evidence-Based Practice barrier scale. Participants' rate of evidence-based practice was 60% (M = 4.2/7), which was significantly correlated with their knowledge (r = 0.739, P less then .01) and attitudes (r = 0.564, P less then .01) of evidence-based practice. The results revealed a 2-predictor model that explained 62.2% of the variance in evidence-based practice among intensive care unit nurses. The 2 variables were attitude (β = 0.
