The relationship between plasma GH profiles and circulating concentrations of insulin-like growth factor 1 (IGF-1) at three different planes of nutrition, chosen to represent a high, medium and low level of nutrition (3%, 1.8% and 1% dry matter of liveweight per day) was studied in 15 young Angus steers. All steers were maintained on 3% dry matter for 5(More)
Somatomedin concentrations in human umbilical sera (n = 206) were measured using a specific radioimmunoassay for insulin-like growth factor (IGF)-I and a specific radioreceptor assay for IGF-II following acid-ethanol extraction of the sera to remove the somatomedin binding proteins. IGF-I concentrations were lower (P less than 0.001) than adult values and(More)
BACKGROUND This cohort study examined the role of smoking during hospitalization, duration of cessation counseling, patient awareness of the hospital's smoke-free policy, belief that smoking is associated with a current symptom or disease, and the presence of withdrawal symptoms with 12-month smoking cessation among inpatients enrolled in a smoking(More)
Plasma samples taken every 30 min over a 26-h period each month from six 4- to 15-month-old red deer stags were analysed for GH. In addition, two samples taken at 10.00 and 22.00 h were analysed for insulin-like growth factor-I (IGF-I) and insulin-like growth factor-II (IGF-II). A concentrate diet was available ad libitum. Food intake, body weight and(More)
Two families of peptides that specifically bind the extracellular domain of the human type I interleukin I (IL-1) receptor were identified from recombinant peptide display libraries. Peptides from one of these families blocked binding of IL-lalpha to the type I IL-1 receptor with IC50 values of 45-140 microM. Affinity-selective screening of variants of(More)
Triazolopyrimidine sulfanilides are a class of highly active herbicides whose primary target is acetolactate synthase. Spontaneous mutants of tobacco (Nicotiana tabacum) (KS-43) and cotton (Gossypium hirsutum) (PS-3 and DO-2) resistant to triazolopyrimidine sulfonanilide were selected in tissue culture. Acetolactate synthase partially purified from the(More)
We have investigated the possibility that IGF-1 may play a role in the regulation of antler development. Plasma IGF-1 concentrations were measured throughout the first period of development of the pedicle and first antler of red deer (Cervus elaphus) to determine whether a relationship existed between growth of antler cartilage (velvet antler) and IGF-1. We(More)
The signs and symptoms of 56 patients with myofascial pain-dysfunction syndrome were tabulated. Patients were classified by age, sex, education and professional background, frequency of complaints of pain, occlusal relationships, oral habits, and specific muscles that were tender on palpation. A coincidence of stress and tension and the onset of myofascial(More)
The N-1-naphthylphthalamic acid (NPA)-binding protein is part of the auxin efflux carrier, the protein complex that controls polar auxin transport in plant tissues. This study tested the hypothesis that the NPA-binding protein (NBP) is associated with the actin cytoskeleton in vitro and that an intact actin cytoskeleton is required for polar auxin transport(More)
Specific radioligand assays for the two somatomedins, insulin-like growth factor (IGF)-I and IGF-II, have been used to study the ontogeny of somatomedin secretion in the perinatal lamb. Plasma samples were obtained from sheep fetuses from 54 days of gestation to term (147 days) and from neonatal lambs. All samples were first extracted in acid-ethanol to(More)
