Loss-of-function experiments were performed to determine the biological functions of SLC16A1-AS in OSCC cells. Silencing SLC16A1-AS1 significantly reduced the cell proliferation rate and colony-forming ability in both CAL27 and SCC25 cell lines. Flow cytometry and western blot analysis revealed that SLC16A1-AS1 silencing induced G0/G1 cell cycle arrest and inhibited the expression of cyclin D1 in both CAL27 and SCC25 cells. In conclusion, our study comprehensively investigated the role of the lncRNA SLC16A1-AS1 in OSCC growth and proved that it may serve as a new diagnostic indicator and a new target for the treatment of OSCC.The COVID-19 pandemic has disrupted healthcare systems around the world, impacting how we deliver medical education. The normal day-to-day routines have been altered for a number of reasons, including changes to scheduled training rotations, physical distancing requirements, trainee redeployment, and heightened level of concern. Medical educators will likely need to adapt their programs to maximize learning, maintain effective care delivery, and ensure competent graduates. Along with a continued focus on learner/faculty wellness, medical educators will have to optimize existing training experiences, adapt those that are no longer viable, employ new technologies, and be flexible when assessing competencies. These practical tips offer guidance on how to adapt medical education programs within the constraints of the pandemic landscape, stressing the need for communication, innovation, collaboration, flexibility, and planning within the era of competency-based medical education.Purpose The primary objective was to inventory what is currently known about faculty development (FD) for competency-based medical educations (CBME) and identify gaps in the literature.Methods A scoping review methodology was employed. Inclusion criteria for article selection were established with two reviewers completing a full-text analysis. Quality checks were included, along with iterative consultation on data collection and consensus decision making via a grounded theory approach.Results The review identified 19 articles published between 2009 and 2018. Most articles (N = 15) offered suggestions as to what should happen with FD in CBME, but few (N = 4) adopted an experimental design. Six main themes were identified with three main features of FD noted across themes (1) The importance of direct and timely feedback to faculty members on their teaching and assessment skills. (2) The role of establishing shared mental models for CBME curricula. (3) That FD is thought of longitudinally, not as a one-time bolus.Conclusion This work illustrates that there is limited, high quality research in FD for CBME. Future FD activities should consider employing a longitudinal and multi-modal program format that includes feedback for the faculty participants on their teaching and assessments skills, including the development of faculty coaching skills.Introduction Chronic kidney disease (CKD) is common, occurring in over 10% of individuals globally, and is increasing in prevalence. The limitations of traditional biomarkers of renal dysfunction, such as serum creatinine, have been well demonstrated in the literature. Therefore, augmenting clinical assessment with newer biomarkers, such as serum cystatin C, has the potential to improve disease monitoring and patient care. Areas covered The present paper assesses the utility and limitations of serum cystatin C as a biomarker for CKD in light of the current literature. Expert opinion Serum cystatin C has been well established as an early and accurate biomarker of CKD that is particularly helpful in patients for whom creatinine is an inadequate marker or for whom more cumbersome methods of glomerular filtration rate (GFR) measurement are impractical. Current research questions are no longer focused on if, but rather when and how often cystatin C should be used in the evaluation of CKD patients. However, transition of all reagents and estimated GFR equations to the newly established International Standard is critical for developing generalizable data.Ultrasonography-derived cross-sectional area (CSA) and echo intensity (EI) are increasingly utilized by investigators to study muscle size and quality, respectively. We sought to examine age, sex, and region (proximal, middle, distal) differences in vastus lateralis and rectus femoris CSA and EI, and determine whether correction for subcutaneous fat thickness influences the magnitude of EI differences. Fifteen younger men (mean age=23 years), fifteen younger women (21 years), eleven older men (74 years), and fifteen older women (70 years) participated. Clear differences were observed among age, sex, and region for vastus lateralis CSA (p≤0.013, d=0.38-0.73), whereas rectus femoris CSA was only different between younger and older participants at the proximal region (p=0.017, d=0.65). Uncorrected EI was greatest at the distal region of both muscles (p less then 0.001, d=0.59-1.38), with only the younger men having significantly lower EI values than the other groups (p≤0.043, d=0.37-0.63). Subcutaneous fat correction resulted in a marked increase in the magnitude of sex-specific EI differences (p≤0.032, d≥0.42). Additionally, subcutaneous fat correction increased the uniformity of EI throughout the thigh. These findings highlight considerable region-specific differences in muscle size and quality among younger and older men and women, and highlight the need to correct for subcutaneous fat thickness when examining EI. Novelty Bullets • Rectus femoris CSA is similar between younger and older adults except at the most proximal site evaluated. • Age- and sex-specific differences in uncorrected EI are non-uniform across the thigh. • Correction for subcutaneous fat thickness substantially increased EI in women, resulting in greater sex differences.Purpose The lacrimal glands produce the aqueous component of the pre-ocular tear film, which is essential for ocular health and optimal vision. This review explores its history, current understanding, recent advances, and scope for future research. selleckchem Methods The authors reviewed the major studies discussing the history of lacrimal glands and their anatomical description, including microscopic anatomy, innervation patterns, imaging, and ongoing translational research. Results The review traces the evolution of human knowledge about the source of tears across several millennia, with specific emphasis on the individuals who made seminal contributions to this field. It provides a detailed update on the morphology, microscopic structure, innervation, vascular supply, and imaging modalities of both the main and accessory lacrimal glands. The review also summarizes the recent advances in lacrimal gland regeneration and repair for the treatment of dry eye disease, particularly the role of mesenchymal stem cells. Lastly, the review gazes into the future of lacrimal gland research, which aims at translating the existing laboratory knowledge into clinical application, with the possibility of transplanting in vitro cultivated lacrimal constructs or the use of cell-based therapies for in situ repair of diseased human lacrimal glands.
