In the present study, expression of pituitary adenylate cyclase-activating polypeptide (PACAP) in rat dorsal root ganglion (DRG) neurons and sciatic nerve following experimental sciatic nerve compression was studied with the use of quantitative immunohistochemistry and in situ hybridization. Previously, we have investigated changes in PACAP expression after nerve transection and, here, the far mor

Primary infection by group A streptococci (GAS) takes place at either the throat or skin of the human host, often leading to pharyngitis or impetigo, respectively. Many GAS strains differ in their preference for throat and skin tissue sites. Previous epidemiological findings show that many of the strains displaying strong tropism for the skin have a high-affinity binding site for plasminogen, loca

The effect of rapid lowering of blood glucose on cerebral blood flow (CBF) was studied in 10 Type 1 (insulin-dependent) diabetic patients (age 23.5 ± 3.8 years; mean ± S.D.) with longstanding, poor metabolic control (HbA1c 11.2 ± 1.0%; normal value 4.0–5.3%) using an intravenous xenon 133 single photon emission computed tomography technique. After a fall in blood glucose, during 81 ± 11 min (mean

Patients with multiple myeloma ( MM) have an increased risk of deep venous thrombosis (DVT), particularly when treated with immunomodulatory drugs. Recently, 2 small hospital-based studies observed persons with the MM precursor condition, monoclonal gammopathy of undetermined significance (MGUS), to be at increased risk of developing DVT. Among 4 196 197 veterans hospitalized at least once at US V

The nexus of international cooperation and international organization is the focus of this article. It proceeds from a critique of extant approaches. Specifically, the relative negligence of organization theory in the study of international organization and the overreliance on structural theories in the study of international cooperation are noted. An interorganizational perspective is proffered a

Incubation was for a long time considered to be a period of decreased activity and low cost for parents. It was therefore ignored as a potential factor affecting life-history trade-offs in birds. Lately this view has started to change, and studies now show that there might be considerable costs connected to incubation. We experimentally reduced the nest temperature during incubation in blue tits C

Mutations that cause a block in a late step of the protoheme IX biosynthetic pathway, i.e., in a step after uroporphyrinogen III, map at 94 degrees on the Bacillus subtilis chromosomal genetic map. We have cloned and sequenced the hem genes at this location. The sequenced region contains six open reading frames: ponA, hemE, hemH, hemY, ORFA, and ORFB. The ponA gene product shows over 30% sequence

Health risks associated with exposure to airborne particulate matter (PM) have been shown epidemiologically as well as experimentally, pointing to both respiratory and cardiovascular effects. These health risks are of increasing concern in society, and to protect public health, a clarification of the toxic properties of particles from different sources is of importance. Lately, wear particles gene

Recent work identifies two kinases required for phosphorylation of proteins of chloroplast thylakoid membranes. One kinase, STN7, is required for phosphorylation of light-harvesting complex II; another, STN8, is required for phosphorylation of photosystem II. How do these kinases interact, what do they do, and what are they for?

Purpose: To describe a technique that facilitates the safe introduction of aortic stent-grafts through diseased iliac arteries. Technique: The technique involves relining and dilating ("paving and cracking") stenosed iliac arteries with covered stents prior to the introduction of the main aortic stent-graft. It has been successfully used to introduce aortic stent-grafts in patients where other tra

The ratio of the change of the clip-gage measured crack-opening displacement of a three-point bend specimen to the change of the displacement at the point of application of the cyclic load is shown to vary linearly with the ratio of the crack length to the specimen height. With the aid of this relation, the crack-growth rate is obtained by numerical differentiation of the crack length with respect

Patients with velopharyngeal insufficiency (VPI) without cleft palate, who appear for the first time in adulthood for treatment, will probably reveal a high percentage of undiagnosed myotonic dystrophy (MD). Videoradiography of deglutition and speech reveals the diagnosis. Eleven adult noncleft palate patients with VPI were studied with videoradiography of the pharynx and esophagus. Three exhibite

INTRODUCTION: A diet containing a high amount of fat has been shown, in short-term studies, to increase the expression of pancreatic lipase and colipase. AIM: To investigate the effects of long-term high-fat-feeding (113 days) on the mRNA expression of pancreatic lipase, colipase, pancreatic lipase-related proteins (1 and 2), and uncoupling proteins during the development of obesity and glucose in

PRELP is a heparin-binding leucine-rich repeat protein in connective tissue extracellular matrix. In search of natural ligands and biological functions of this molecule, we found that PRELP binds the basement membrane heparan sulfate proteoglycan perlecan. Also recombinant perlecan domains I and V carrying heparan sulfate bound PRELP, whereas other domains without glycosaminoglycan substitution di
