The purpose of this study was to compare the prevalence and implications of expiratory flow limitation (EFL) during exercise in boys and girls. Forty healthy, prepubescent boys (B; n=20) and girls (G; n=20) were tested. Subjects completed pulmonary function tests and an incremental cycle maximal oxygen uptake (VO2max) test. EFL was recorded at the end of(More)
The case records of 128 patients receiving 129 transfusions of 20 or more units of blood within a 24-hour period at Detroit Receiving Hospital, between August 1980 and August 1985, were reviewed. In patients receiving 20 to 49 units of blood, without pre-existing disease or prolonged shock, the mortality rate was 36 per cent (15/42). In similar patients who(More)
INTRODUCTION The prevalence of both childhood obesity and childhood asthma has increased dramatically over the past few decades. Little is known concerning the role of body composition and lifestyle influences on airway health in children. PURPOSE To determine whether body composition, fruit and vegetable intake (FV) and physical activity (PA) impact(More)
The fingernails of a woman with pachyonychia congenita were ablated by several different methods. The most effective, most rapidly performed, and most acceptable method was vigorous curettage and electrofulguration of the matrices and beds of the nails. The responses to treatment suggest that the matrix, rather than the bed, is the site from which the(More)
Previous studies have implicated protein kinase C (PKC) in colon carcinogenesis, but a clear understanding of the role of PKC in colon cancer is lacking. The purpose of this study was to investigate the effects of dexniguldipine hydrochloride (DNIG) on the in vitro growth of HT-29 human colon carcinoma cells and the expression of PKC isoforms. DNIG is a(More)
New therapeutic regimens are needed for the treatment of pancreatic cancer. In view of the importance of protein kinase C (PKC) in tumorigenesis, we evaluated the effects of dexniguldipine hydrochloride (DNIG) on the in vitro growth of CFPAC-1 human pancreatic adenocarcinoma cells and the expression of PKC isoforms. DNIG is a potent antineoplastic drug with(More)
This study compared cardio-respiratory responses during running wearing a motion control shoe (MC) or a cushioning shoe (CU) in a cross-over single blinded design. Fourteen runners (10F/4M, age=27.3+/-5.1 years, body mass=64.1+/-12.2 kg, height=167.8+/-7.5 cm, VO (2)max=52.3+/-8.8 ml/kg/min) completed a 40-min run at approximately 65% VO (2) max under both(More)
The effects of a variety of inhibitors of the arachidonic acid metabolic pathway have been tested on the growth of early erythroid progenitor cell-derived colonies (CFU-E and BFU-E) in an attempt to discern whether products of the cyclo-oxygenase pathway or lipoxygenase pathway are essential for erythropoiesis. Murine erythroid progenitor cells obtained(More)
