METHODS An electronic survey was distributed to academic radiology department heads within the faculties of medicine at Canadian universities between September and October 2019. Respondents identified the number of partnership track radiologists hired in the last academic year, the number of fellowship-trained new hires, and the top 3 subspecialties for new and prospective hires. Descriptive statistics were used to summarize the data. selleck products RESULTS Nine academic radiology department heads responded to the survey (75% response rate) with good regional representation across Canada. Ninety-five percent of new hires within the last academic year were subspecialty fellowship trained. The top subspecialties for new hires in the last year were abdominal imaging and interventional neuroradiology, with 77.8% and 44.4% of academic leaders reporting them as one of the top 3 subspecialties, respectively. The top 3 subspecialties for prospective hires in the next academic year included musculoskeletal imaging (n = 6, 66.7%), followed by abdominal imaging (n = 5, 55.6%), with pediatric radiology (n = 3, 33.3%) and cardiothoracic imaging (n = 3, 33.3%) tying for third place. There was some variability in the subspecialty needs for hires between regions. CONCLUSIONS The survey results provide valuable information about the current and future subspecialty needs of academic radiology practices. The data obtained can provide guidance to trainees regarding fellowship training options that will optimize their future employability.Polyphenols are naturally occurring compounds in plants and they are the most abundant antioxidants in the human diet. Due to their considerable structural diversity, this largely influences their bioavailability. Since a large proportion of polyphenols remains unabsorbed along the gastrointestinal tract, they may accumulate in the large intestine, where most of them are extensively metabolized by the intestinal microbiota. The formation of bioactive polyphenol-derived metabolites may also benefit the health status of the subjects, although the mechanisms have not been delineated. This review aims to highlight the impact of polyphenols on gut health and the modes of action could be through modulation of intestinal barrier function, innate and adaptive immune response, signaling pathways, as well as the ability to modify gut microbiota composition. The review will conclude by presenting future perspective and challenges of polyphenols application in food products to be used for preventing or treating diseases.Aim To assess differential expression profiles of miRNAs in exosomes derived from human peripheral blood (PB) and umbilical cord blood (UCB). Materials & methods Small RNA sequencing was performed to characterize the miRNA expression in plasma exosomes processed from UCB of five healthy newborns and PB of five normal adult volunteers, and differentially expressed miRNAs were further analyzed. Results A total of 65 exosomal miRNAs, including 46 upregulated and 19 downregulated, showed differential expression between UCB and PB. Target genes of these miRNAs were mainly enriched in signaling pathways associated with pregnancy, cancers, cell mobility and nervous system. Conclusion Exosomal miRNAs may have essential roles in the biological functions of UCB, suggesting the therapeutic and biomarker potentials of exosomes in UCB.Cyclin-dependent kinase 7 (CDK7) plays crucial roles in the regulation of cell cycle and transcription that are tightly associated with cancer development and metastasis. The recent identification of the first covalent inhibitor which possesses high specificity against CDK7 prompts intense studies on designing highly selective CDK7 inhibitors and exploring their applications in cancer treatments. This review summarizes the latest biological studies on CDK7 and reviews the development of CDK7 inhibitors in preclinical and clinical evaluations, along with the prospects and potential challenges in this research area. CDK7 is an attractive anticancer target, and the discovery and development of CDK7 inhibitors has received much attention.The human bronchial epithelium is an important barrier tissue that is damaged or pathologically altered in various acute and chronic respiratory conditions. In order to represent the epithelial component of respiratory disease it is essential to use a physiologically-relevant model of this tissue. The human bronchial epithelium is a highly organized tissue consisting of a number of specialized cell types. Primary human bronchial epithelial cells (HBEC) can be differentiated into a mucociliated tissue in air-liquid interface (ALI) cultures using appropriately supplemented media under optimized growth conditions. We compared the histology, ciliary length and function, diffusion, and barrier properties of HBEC from donors with no respiratory disease grown in two different media, PneumaCultTM-ALI or BEDM. In the former group, the HBEC have a more physiological pseudostratified morphology and mucociliary differentiation, including increased epithelial thickness, intracellular expression of airway-specific mucin protein MUC5AC, and total expression of cilia basal-body protein compared to cells from the same donor grown in the other medium. Baseline expression levels of inflammatory mediators, TSLP, soluble ST2, and eotaxin-3 were lower in PneumaCultTM-ALI. In addition, the physiological cilia beat frequency and electrical barrier properties with trans-epithelial electrical resistance were significantly different between the two groups. Our study has shown that these primary cell cultures from the same donor grown in the two media possess variable structural and functional characteristics. Therefore, it is important to objectively validate the primary epithelial cell cultures prior to experimentation to ensure they are appropriate to answer a specific scientific question.
