Muscle Progenitor Cell Fusion in the Maintenance of Skeletal Muscle.

Skeletal muscle possesses a resident, multipotent stem cell population that is essential for its repair and maintenance throughout life. Here I highlight the role of this stem cell population in muscle repair and regeneration and review the genetic control of the process; the mechanistic steps of activation, migration, recognition, adhesion, and fusion of these cells; and discuss the novel recognition of the membrane signaling that coordinates myogenic cell-cell fusion, as well as the identification of a two-part fusogen system that facilitates it.

Science surrounding the safe use of bioactive ingredients in infant formula: federal comment.

Less than a quarter of U.S. infants meet the federal recommendation for exclusively breastfeeding to 6 months of age, necessitating access to safe and effective infant formula.

Review of the efficacy of infrared thermography for screening infectious diseases with applications to COVID-19.

The recent coronavirus disease 2019 (COVID-19) pandemic, which spread across the globe in a very short period of time, revealed that the transmission control of disease is a crucial step to prevent an outbreak and effective screening for viral infectious diseases is necessary. Since the severe acute respiratory syndrome (SARS) outbreak in 2003, infrared thermography (IRT) has been considered a gold standard method for screening febrile individuals at the time of pandemics. The objective of this review is to evaluate the efficacy of IRT for screening infectious diseases with specific applications to COVID-19.

Risks factors and timing of genital human papillomavirus (HPV) infection in female stem cell transplant survivors: a longitudinal study.

This longitudinal single-center study describes the timing and risk factors for genital human papillomavirus (HPV) disease in women after allogeneic hematopoietic cell transplantation (HCT). Between 1994 and 2014, 109 females underwent HCT of whom 82 surviving transplant for >1 year had regular, comprehensive genital tract assessment and treatment of HPV disease. The cumulative proportions of any genital HPV infection at 1, 3, 5, 10 and 20 years were 4.
