Technological advancements today allow researchers to de-differentiate fibroblasts into induced pluripotent stem cells and re-differentiate them into dopaminergic neurons. Few studies based on this technique address possible neuroprotective effects of PINK1, including mitophagy and mitochondrial homeostasis, but underline the need for a broader characterization of its function in neurons.Oxidative stress is one of the major issues associated with cryopreservation because it causes a marked reduction in the post-thaw quality of semen. This study investigated the ability of kinetin to preserve the structural and functional integrity of dog sperm during cryopreservation. Pooled ejaculates were divided into 5 equal aliquots, diluted with buffer 2 supplemented with different concentrations of kinetin (0, 25, 50, 100, and 200 μM), and finally cryopreserved. The optimal concentration of kinetin was 50 μM based on the significantly improved (P less then 0.05) motion characteristics and viability of post-thaw sperm samples. Moreover, kinetin-supplemented samples exhibited significantly higher (P less then 0.05) sperm counts with the intact plasma membrane, normal acrosomes, mitochondria, and chromatin than control. The beneficial effects of kinetin were also reflected by the significant increase in the expression levels of anti-apoptotic (B-cell lymphoma, BCL2) and protamine-related genes (protamine 2, PRM2; protamine 3, PRM3), and decrease in the expression of pro-apoptotic (BCL2-associated X, BAX) and mitochondrial reactive oxygen species-modulating genes (ROS modulator 1, ROMO1) in kinetin-supplemented sperm samples than in control. read more The results demonstrated that supplementation of buffer 2 with 50 μM kinetin is ideal for reducing the magnitude of oxidative damage during semen cryoprocessing and improving the post-thaw quality of dog semen.Background Professional society guidelines recommend against routine early antibiotic use in the treatment of asthma exacerbation without comorbid bacterial infection. However, high antibiotic prescribing rates have been reported in developed countries, OBJECTIVE We assessed the effectiveness of this strategy in the routine care of children. Methods Using data on 48,743 children hospitalized for asthma exacerbation with no indication of bacterial infection during 2010-2018, we conducted a retrospective cohort study to compare clinical outcomes and resource utilization between children who received early antibiotic treatment and those who did not. Results Overall, 19,866 children (41%) received early antibiotic treatment. According to the propensity score matching analysis, children with early antibiotic treatment had longer hospital stay (mean difference, 0.21 days; 95% confidence interval [CI], 0.18-0.28), higher hospitalization costs (mean difference, 83.5 US dollars; 95% CI, 62.9-104.0), and higher risk of probiotic use (risk ratio, 2.01; 95% CI, 1.81-2.23) than children who did not receive early antibiotic therapy. Similar results were found from inverse probability of treatment weighting, G-computation, and instrumental variable methods and sensitivity analyses. The risks of mechanical ventilation and 30-day readmission were similar between the groups or slightly higher in the treated group, depending on the statistical models. Conclusions Antibiotic therapy may be associated with prolonged hospital stay, elevated hospitalization costs, and high risk of probiotic use without improving treatment failure and readmission. Our findings highlight the need for reducing inappropriate antibiotic use among children hospitalized for asthma.Atopic dermatitis (AD) is the most common inflammatory skin condition. Skin barrier dysfunction is of major importance in AD as it facilitates allergen sensitization and systemic allergic responses. Long regarded as a pro-apoptotic protease, emerging studies indicate granzyme B (GzmB) to have extracellular roles involving the proteolytic cleavage of extracellular matrix, cell adhesion- and basement membrane -proteins. Minimally expressed in normal skin, GzmB is elevated in AD and positively correlated with disease severity and pruritus. We hypothesized that GzmB contributes to AD through extracellular protein cleavage. A causative role for GzmB was assessed in an oxazolone-induced murine model of dermatitis, comparing GzmB-/- to wild-type mice, showing significant reductions in inflammation, epidermal thickness and lesion formation in GzmB-/- mice. Topical administration of a small molecule GzmB inhibitor reduced disease severity compared to vehicle-treated controls. Mechanistically, GzmB impaired epithelial barrier function through E-cadherin and filaggrin cleavage. Together, GzmB proteolytic activity contributes to impaired epidermal barrier function and represents a valid therapeutic target for AD.The use of the left ventricle as the sub-pulmonary ventricle in order to achieve a 1.5 or biventricular circulation is feasible in heterotaxy patients with complex intra-cardiac anatomy and acceptable right ventricular function. It is an alternative in patients who are not ideal candidates for single ventricle palliation. We highlight two cases where patients were rescued from a failed Fontan palliation and demonstrated improved functional status with normal saturations.Background Feeding jejeunostomy is frequently utilised to ensure nutritional intake after esophagectomy. Early return to diet is demonstrated to enhance recovery in major abdominal surgery. Early oral feeding is safe and effective in recent randomised control trials in esophagectomy. This study assesses implications of eliminating insertion of jejeunostomy after esophagectomy. Methods A retrospective study was undertaken between 2014-2017 with follow up over the first year. 50 patients did not have a jejeunostomy compared to 46 patients who followed conventional practice. Outcomes measured included change in relative weight and body mass over one year, complications and nutritional reinterventions. Results Median weight loss at one year was 10.7kg (-8 to 55.6) while median percentage weight loss was 12% (-10.1% to 39.2%). Patients without jejeunostomy lost more weight during the first month (p=0.002). Thereafter, at 6/12months there were no differences in actual or relative weight loss. Obese patients lost more weight in the non jejeunostomy group compared to those with jejeunostomy (9.
