A divalent antibody format is required for neutralization of human cytomegalovirus via antigenic domain 2 on glycoprotein B

Glycoprotein B (gB) of human cytomegalovirus (HCMV) is the dominating protein in the envelope of this virus and gives rise to virus-neutralizing antibodies in most infected individuals. We have previously isolated a neutralizing human antibody specific for antigenic domain 2 (AD-2) on gB, a poorly immunogenic epitope, which nevertheless is capable of eliciting potent neutralizing antibodies. In or

Potential benefits of muscarinic M-3 receptor selectivity

Detrusor smooth muscle contains muscarinic receptors of the M-2 (approximate to2/3) and M-3 (approximate to1/3) subtypes. M-3 receptors are mainly responsible for normal micturition contraction, whereas, the role Of M-2 receptors has not yet been clarified. In certain disease states, M-2 receptors may also contribute to bladder contraction. Different muscarinic receptor subtypes can contribute to

Microarthropods mediate sperm transfer in mosses

Among flowering plants, animals commonly act as pollinators. We showed that fertile moss shoots attract springtails and mites, which in turn carry moss sperm, thereby enhancing the fertilization process. Previously, fertilization of mosses was thought to depend on the capacity of individual sperm to swim through a continuous water layer. The role of microarthropods in moss fertilization resembles

Plasma fibronectin supports neuronal survival and reduces brain injury following transient focal cerebral ischemia but is not essential for skin-wound healing and hemostasis

Fibronectin performs essential roles in embryonic development and is prominently expressed during tissue repair. Two forms of fibronectin have been Identified: plasma fibronectin (pFn), which Is expressed by hepatocytes and secreted In soluble form into plasma; and cellular fibronectin (cFn), an insoluble form expressed locally by fibroblasts and other cell types and deposited and assembled into t

Repeatability of sonographic measurements in clubfeet

Purpose: To assess the intra- and interobserver agreement of ultrasound assessment of clubfoot patho-anatomy in early childhood. Material and Methods: Seventeen clubfeet in 12 children were sequentially scanned by 2 examiners and repeat assessments were carried out independently. Three well-defined imaging planes were chosen to evaluate navicular displacement: the medial malleolus-navicular (MM-N)

Health care utilisation in a developing country -the case of Zambia

Popular Abstract in Swedish Syftet med denna avhandling är att bidra till vår förståelse för vårdutnyttjande och dess förklaringsfaktorer i utvecklingsländer, speciellt i sub-sahariska Afrika. Detta görs genom att fokusera på sjukvårdsutgifter och dess förklaringsfaktorer, samt valet att söka vård för att bota åkomman. Datamaterialete som används kommer från en hushållsundersökning från 1998 omfatThe aim of this thesis is to contribute to our understanding of health care utilisation and its determinants in developing countries, especially in sub-Saharan Africa. This is done by explicitly focusing on health care expenditures and its determinants as well as the choice to seek health care to cure the illness. Firstly, the focus is on a household’s expenditures for health care. The aim of this

Disseminated infection with Encephalitozoon intestinalis in AIDS patients: Report of 2 cases

Microsporidiosis must be regarded as a late opportunistic infection when HIV is advanced. In this article we describe 2 cases of disseminated infection with Encephalitozoon intestinalis. The first case had a local intestinal infection for > 1 y before it disseminated and microsporidia were found intracellularly in sputum. In the second case, spores were initially found in conjunctival cells, sinus

Identification of Isomeric States "South" of Pb-208 via Projectile Fragmentation

Relativistic fragmentation of Pb-208 has been used to produce excited states in neutron-rich nuclei with N approximate to 126. Spectroscopic information for a range of nuclei has been obtained through observing delayed gamma-ray emissions from isomeric states. Preliminary results for Pt-203,Pt-204 nuclei are presented. For the first time, excited states have been observed in Pt-203 and Pt-204. The

Carbohydrate groups of alpha1-microglobulin are important for secretion and tissue localization but not for immunological properties

The role of the carbohydrates for the structure and functions of the plasma and tissue protein alpha1-microglobulin (alpha1m) was investigated by deletion of the sites for N-glycosylation by site-directed mutagenesis (N17,96-->Q). The mutated cDNA was expressed in a baculovirus-insect cell system resulting in a nonglycosylated protein. The biochemical properties of N17,96Q-alpha1m were compared to

The human V-preB promoter is a target for coordinated activation by early B cell factor and E47.

The development of mature B lymphoid cells involves a highly orchestrated regulation of stage- and lineage-specific genes. In this study, we report an analysis of the human surrogate L chain VpreB promoter. The promoter has an overall homology of 56% to the mouse counterpart and displays a preB cell-restricted activity in transient transfections in cell lines. The promoter harbors three independen

Comparison of flanged and unflanged acetabular cup design.

Background and purpose Adequate depth of cement penetration and cement mantle thickness is important for the durability of cemented cups. A flanged cup, as opposed to unflanged, has been suggested to give a more uniform cement mantle and superior cement pressurization, thus improving the depth of cement penetration. This hypothesis was tested experimentally. Materials and methods The same cup desi

Genetic Variants Associated With Glycine Metabolism and Their Role in Insulin Sensitivity and Type 2 Diabetes

Circulating metabolites associated with insulin sensitivity may represent useful biomarkers, but their causal role in insulin sensitivity and diabetes is less certain. We previously identified novel metabolites correlated with insulin sensitivity measured by the hyperinsulinemic-euglycemic clamp. The top-ranking metabolites were in the glutathione and glycine biosynthesis pathways. We aimed to ide
