Background: The COVID-19 pandemic has accelerated the transition to remote work, leading to increased attention on presenteeism and absenteeism among remote workers. Understanding the implications of these phenomena on worker health and productivity is crucial for optimizing remote work arrangements and developing policies to improve employee well-being.
Objectives: This scoping review aims to examine the occurrence of presenteeism and absenteeism among remote workers during the COVID-19 pandemic and the interrelated physical and mental health issues during these periods.
A radioimmunoassay specific for the C-terminus of human prothymosin alpha was developed using the synthetic peptide [Cys-Aca degrees]-human prothymosin alpha (90-109)-OH coupled to KLH as antigen and the analogue [Tyr-Aca degrees]-human prothymosin alpha (90-109)-OH labelled with 125I as tracer. The radioimmunoassay measured intact prothymosin alpha, in the range of 2-100 pmol and does not cross-react with the partly homologous polypeptide parathymosin alpha. A major epitope was located in the segment 95-107.

1. Soluble esterases of digestive system organs of various developmental stages in the quail (Coturnix coturnix) were resolved by polyacrylamide gel electrophoresis into several molecular forms which were characterized as carboxylesterases, acetylesterases, cholinesterases and esterases sensitive to eserine. 2.
View Article and Find Full Text PDFA new radioimmunoassay has been developed for thymosin beta 4 by generating rabbit polyclonal antibodies against the synthetic N-terminal peptide fragment 1-15 coupled to KLH. The synthetic analogue [Tyr12]-thymosin beta 4 (1-15) was used as tracer. This radioimmunoassay, with a useful range of 10-1000 pmoles, showed cross-reactivity with the second homologous beta-thymosin of man and rat (thymosin beta 10) but not of calf (thymosin beta 9).
View Article and Find Full Text PDFTwo forms of beta-thymosins, designated thymosin beta 11 and thymosin beta 12, were isolated from trout (Salmo gairdneri) spleen. This suggests that the presence of two beta-thymosins, previously thought to be a property of mammalian tissues only, is a more general phenomenon in vertebrate species. Both trout beta-thymosins were found to be N-terminally blocked by a group identified as acetyl by m.
