Further, controlling ankle plantar flexion to ensure efficient impact mechanics may be important for skilled kicking. Practitioners should consider how choice of filter will affect their data, and use of time-frequency methods can help inform empirically grounded coaching practices.Biological processes are accomplished by the coordinated action of gene products. Gene products often participate in multiple processes, and can therefore be annotated to multiple Gene Ontology (GO) terms. Nevertheless, processes that are functionally, temporally and/or spatially distant may have few gene products in common, and co-annotation to unrelated processes probably reflects errors in literature curation, ontology structure or automated annotation pipelines. We have developed an annotation quality control workflow that uses rules based on mutually exclusive processes to detect annotation errors, based on and validated by case studies including the three we present here fission yeast protein-coding gene annotations over time; annotations for cohesin complex subunits in human and model species; and annotations using a selected set of GO biological process terms in human and five model species. For each case study, we reviewed available GO annotations, identified pairs of biological processes which are unlikely to be correctly co-annotated to the same gene products (e.g. amino acid metabolism and cytokinesis), and traced erroneous annotations to their sources. To date we have generated 107 quality control rules, and corrected 289 manual annotations in eukaryotes and over 52 700 automatically propagated annotations across all taxa. Actinic keratosis (AK) is a pre-cancerous skin lesion, associated with development of squamous cell carcinoma. Current treatment options are limited. To compare the efficacy and safety of topical 5-fluorouracil cream (5-FU) and potassium hydroxide 5% (KOH) in the treatment of AK. Eighteen patients with AK applied KOH solution or 5-FU on each side of their scalp/face, randomly. The efficacy and safety of these treatments were compared. Thirteen (118 lesions) and ten (83 lesions) patients were successfully followed for one and three months, respectively. After one month, KOH showed a better clinical response (81% vs. 58%; -value = 0.007) and dermoscopic response (KOH, 65% vs. 5-FU, 46%; -value = 0.04); while no differences were noted after three months (clinical response, 83% vs.70%, -value = 0.1; dermoscopic response, 76% vs. 59%, -value = 0.1). No significant differences in the recurrence rate of the lesion between the two groups were noted at the end of the third month ( -value = 0.5). Regarding the safety of the treatments, the risk of developing erythema, scaling, sand swelling was higher in 5-FU group ( -value < 0.0001, for all), while more patients in KOH group had erosion and ulcer ( -value < 0.001 for both). KOH was up to 96% less expensive than 5-FU. Low number of patients and short-term follow-up limited the analysis. KOH solution offers a faster and less expensive resolution of AK lesions than does 5-FU.

Universal tumor screening is a strategy to identify high-risk individuals by testing all CRC tumors for molecular features suggestive of Lynch Syndrome. Patient interest in screening and preferences for consent have been underexplored. Methods A postal survey was administered to CRC patients in a Canadian province. Results Most patients (81.4%) were willing to have tumors tested if universal tumor screening were available and were willing to discuss test results with family members and healthcare professionals. The majority (62.6%) preferred informed consent be obtained prior to screening. Conclusion Patients were supportive of universal screening. They expected consent to be obtained, contrary to current practice across Canada and elsewhere.The COVID-19 pandemic has necessitated novel approaches and collaborative efforts across multiple disciplines. It is known that various aspects of our physiology and response to pathogens are under tight clock control. However, the assimilation of circadian biology into our clinical and research practices is still evolving. Using a focused review of the literature and original analyses of the UK Biobank, we discuss how circadian biology may inform our diagnostic and therapeutic strategies in this pandemic.Background Regulator of G-protein signaling 5 (RGS5) is a negative modulator of G-protein-coupled receptors. The role of RGS5 in brain endothelial cells is not known. We hypothesized that RGS5 in brain microvascular endothelial cells may be an important mediator of blood-brain barrier function and stroke severity after focal cerebral ischemia. Methods and Results Using a transient middle cerebral artery occlusion model, we found that mice with global and endothelial-specific deletion of Rgs5 exhibited larger cerebral infarct size, greater neurological motor deficits, and increased brain edema. Staurosporine In our in vitro models, we observed increased Gq activity and elevated intracellular Ca2+ levels in brain endothelial cells. Furthermore, the loss of endothelial RGS5 leads to decreased endothelial NO synthase expression and phosphorylation, relocalization of endothelial tight junction proteins, and increased cell permeability. Indeed, RGS5 deficiency leads to increased Rho-associated kinase and myosin light chain kinase activity, which were partially reversed in our in vitro model by pharmacological inhibition of Gq, metabotropic glutamate receptor 1, and ligand-gated ionotropic glutamate receptor. Conclusions Our findings indicate that endothelial RGS5 plays a novel neuroprotective role in focal cerebral ischemia. Loss of endothelial RGS5 leads to hyperresponsiveness to glutamate signaling pathways, enhanced Rho-associated kinase- and myosin light chain kinase-mediated actin-cytoskeleton reorganization, endothelial dysfunction, tight junction protein relocalization, increased blood-brain barrier permeability, and greater stroke severity. These findings suggest that preservation of endothelial RGS5 may be an important therapeutic strategy for maintaining blood-brain barrier integrity and limiting the severity of ischemic stroke.
