Children and adolescents with poorly controlled type 1 diabetes mellitus (T1DM) are at risk for decreased bone mass. Growth hormone (GH) and its mediator, IGF-1, promote skeletal growth. Recent observations have suggested that children and adolescents with T1DM are at risk for decreased bone mineral acquisition. We examined the relationships between(More)
BACKGROUND AND STUDY AIMS Inadvertent injection of contrast agent into the pancreatic duct is believed to be an important contributor to pancreatitis occurring after endoscopic retrograde cholangiopancreatography (post-ERCP pancreatitis, PEP). Our aim was to examine whether primary deep biliary cannulation with a guide wire is associated with a lower rate(More)
The endocrine effects of drugs on two groups of 12 male sexual offenders in a special hospital were studied. In the first study benperidol, chlorpromazine and placebo were compared and in the second ethynyl oestradiol and cyproterone acetate were compared with no treatment. In the first study there was no difference between the three drugs in their effects(More)
The method of electron dense degeneration has been used to make a quantitative study of the projection from the habenula through the fasciculus retroflexus (FR) to the interpeduncular nucleus (IPN) in the rat. The IPN si a midline structure onto which the right and left fasciculi converge. In the rostral part of the IPN the fascicular axons from each side(More)
OBJECTIVE To determine whether bone characteristics in adolescents with type 1 diabetes mellitus (DM) are influenced by blood glucose regulation and disease duration. The subjects were adolescents with type 1 DM (n=55) recruited from the University of Utah's Primary Children's Pediatric Diabetes Treatment Center. A reference database consisting of 95(More)
OBJECTIVE To track bone mineral acquisition in adolescents with type 1 diabetes (DM). STUDY DESIGN Subjects were adolescents, ages 12 to 18 years, with DM (n=42) and a healthy regional reference (n=199). Measurements of tibia bone characteristics by peripheral quantitative computed tomography (pQCT) and spine and whole body (WB) by dual-energy x-ray(More)
A new monoclonal antibody, specific to an epitope in the carboxyl terminus of the Drosophila collagen IV molecule (basement membrane collagen) was identified. The distributions of collagen IV, laminin, and an additional extracellular molecule, the 2G2 antigen (2G2-Ag), were followed immunocytochemically during early wing development. In late third instar(More)
Daily hormonal studies during nine ovulatory menstrual cycles showed that plasma prolactin and testosterone concentrations fluctuated randomly and independently. Mean plasma testosterone levels were found to be higher during the 7 days before and after the mid-cycle LH peak when compared to the premenstrual phase (P less than 0-01). No correlation was found(More)
BACKGROUND The long-term efficacy of argon plasma coagulation (APC) in the management of gastrointestinal vascular lesions has not been evaluated in a large and well-defined series. The impact of APC on transfusion requirements and hemoglobin, and technical parameters including complications and number of treatment sessions, is assessed in this series. (More)
We have used enhancer trap lines as markers to recognize glial cells in the wing peripheral nervous system of Drosophila melanogaster. Their characterization has enabled us to define certain features of glial differentiation and organization. In order to ask whether glial cells originate within the disc or whether they migrate to the wing nerves from the(More)
