OBJECTIVE To examine whether women's tobacco use prior to entering the US Navy is predictive of subsequent career performance. A priori predictions were that smoking at entry into the Navy would be related to early attrition, poorer job performance, more disciplinary problems and lower likelihood of re-enlistment. METHODS A prospective cohort analysis of 5487 women entering the US Navy betwee...

T H E UNITED STATES Navy was a proud participant in the vast preparation and the farflung operational activities which, in bold exhibitions of professional skill, culminated in our first manned space fl.ights. In terms of magnitude, this represented the largest concentrated effort the Navy has ever put forth in a peaceful enterprise. In terms of sacrifice, many important tasks were temporarily ...

A skeletal examination of fetuses is required in regulatory embryo-fetal development studies. This chapter describes a method of skeletal examination using alizarin staining. All fetuses are removed from the mother by caesarean section before birth. The fetuses are first examined externally. For larger species (rabbit and minipig), an internal examination can be performed on the fresh soft tiss...

Background & Aim: Rubiatinctorum is one of the most well-known medicinal plants whose alizarin and other anthraquinones which are outstanding color agents with some trace of pharmaceutical properties are isolated from it. The objective of this study was to optimize alizarin production in intact plant of R.tinctorum by induction with biotic elicitors. ...

This study aimed to culture and characterize mesenchymal stem cells derived from meniscal debris. Cells in meniscal debris from patients with meniscal injury were isolated by enzymatic digestion, cultured in vitro to the third passage, and analyzed by light microscopy to observe morphology and growth. Third-passage cultures were also analyzed for immunophenotype and ability to differentiate int...

The gene for polysyndactyly (Ps) arose during a neutron irradiation experiment at the M.R.C. Radiobiological Unit at Harwell (Batchelor, Phillips & Searle, 1966), and was offered to the author in November 1964. The mice from Harwell were outcrossed to CB $? (the Fx of CBA/Gr &?xC57 BL/Gr $?). The stock was outcrossed again in late 1966 to improve fertility. Rigorous brother/sister mating has no...
