The Stress Of Fathers During The Labor And Delivery Of Their Partner, Deann Robinson Brown
The Stress Of Fathers During The Labor And Delivery Of Their Partner, Deann Robinson Brown
UNLV Retrospective Theses & Dissertations
This descriptive, retrospective survey employed a questionnaire to determine what factors cause stress to expectant fathers during their partner's labor and delivery and how that stress is exhibited. Fathers of healthy newborns at two hospitals in Utah accompanying their partner in labor and delivery were asked to complete the questionnaire within 36 hours after the birth of their baby. The survey elicited responses from three different time periods during the labor and delivery: (1) the beginning of labor; (2) labor from the time of admission to the hospital and when labor reached its peak until delivery; and (3) during the …
Myceloid Cell Formation In Arthrobacter Globiformis During Osmotic Stress, Ganegodage Shyama Perera
Myceloid Cell Formation In Arthrobacter Globiformis During Osmotic Stress, Ganegodage Shyama Perera
UNLV Retrospective Theses & Dissertations
Arthrobacters exhibit a dimorphic growth cycle where exponential phase cells appear as irregular bacilli and stationary phase cells as cocci. Arthrobacter globiformis was found to form myceloids when subjected to osmotic stress. Addition of known osmoprotective compounds did not relieve this effect. Since myceloid formation may result from altered penicillin-binding proteins (PBPs), PBP profiles of stressed and unstressed A. globiformis were studied. Eight PBPs were identified, ranging in molecular mass from 91,000 to 30,000 daltons. Myceloids appeared to lack PBP 2a (84 kD) and PBP 2b (82 kD) in all growth conditions. The myceloids were 12-20 times more sensitive to …
