The importance of screening programs in reducing the prevalence of genital chlamydial infections is stressed by the fact that the majority of infected persons are more or less asymptomatic. The use of oral contraceptives may mask infections affecting the upper genital tract. This imposes selective screening and rescreening of women with a history of pelvic inflammatory disease. The recent knowledg

This paper presents theory for stability analysis and design for a class of observer-based feedback control systems. Relaxation of the controllability and observability conditions imposed in the Yakubovich-Kalman-Popov (YKP) lemma can be made for a class of nonlinear systems described by a linear time-invariant system (LTI) with a feedback-connected cone-bounded nonlinear element. It is shown how

AIM: To study the interaction between the human cysteine proteinase inhibitor, cystatin C, and proteinases of periodontitis associated bacteria. METHODS: Gingival crevicular fluid samples were collected from discrete periodontitis sites and their cystatin C content was estimated by enzyme linked immunosorbent assay (ELISA). The interaction between cystatin C and proteolytic enzymes from cultured s

Research has been done on children’s participation in review meetings, a method for reviewing foster and residential care. The method is tested within the national project Children’s Needs in Focus (BBIC) inspired by the British Integrated Children’s System and operated by the National Board of Health and Welfare (Socialstyrelsen) in Sweden. The objective of the evaluation, conducted on behalf of

Background Sick leave due to neck, shoulder and back disorders (NSBD) is higher among health-care workers, especially nursing aides/assistant nurses, compared with employees in other occupations. More information is needed about predictors of sick leave among health care workers. The aim of the study was to assess whether self-reported factors related to health, work and leisure time could predict

The spatial distribution of genetic markers can be useful both in estimating patterns of gene flow and in reconstructing biogeographic history, particularly when gene genealogies can be estimated. Genealogies based on nonrecombining genetic units such as mitochondrial and chloroplast DNA often consist of geographically separated clades that come into contact in narrow regions. Such phylogeographic

We evaluated asthma control and medication use 5 years after introduction of an inhaled corticosteroid (budesonide via Turbuhaler(R)) in 462 patients with persistent asthma and symptoms of different duration. An early treatment group with symptoms for

We present a simple model for the arterial part of the cardiovascular system, based on Poiseuille flow constrained by the power dissipated into the cells lining the vessels. This, together with the assumption of a volume-filling network, leads to correct predictions for the evolution of vessel radii, vessel lengths and blood pressure in the human arterial system. The model can also be used to find

Det påstås att organisationer som får sin finansiering från en marknad har ett tydligt krav på att anpassa sig efter kundernas behov. Erbjuder de tjänster och/eller produkter som ingen vill ha går de på kort sikt med förlust. Om inget görs väntar på längre sikt konkurs. Långsiktig överlevnad handlar för dessa organisationer om att över lång tid erbjuda det som kunder av olika anledningar anser sig

An east-west regional gradient in cardiovascular mortality was found within seven counties in mid-Sweden during the years 1969-1983. The mortality differences were of considerable magnitude for ischaemic heart disease (IHD) as well as for stroke. In previous reports, in which the distribution of risk factors among middle-aged men was presented, the moderate variation among the communities could no

Popular Abstract in Swedish Fartygsgenererade vågor ofta orsakar större kustförändringar jämfört med vindvågor utmed stränder där stryklängden är begränsad. Med bakgrund av att fartygstrafiken, särskilt från höghastighetsfärjor, och dess potentiella miljöeffekter har forskning inom detta område ökat. Fast att ett antal studier har och fortsätter undangöras, forskning om fartygsgenererade vågor ochIn navigable waterways, owing to the relatively short fetches for wind wave generation, the free waves generated by moving vessels often produce the dominant wave action with respect to erosion of the shore. In response to the fairly recent introduction of high-speed ferries, combined with a planned expansion within the passenger- and car-carrying ship market, the need to model and predict coastli

Type 1 diabetes (T1D) is an autoimmune disease characterized by pancreatic beta cell destruction involving auto-reactive T-cells, pro-inflammatory cytokines, reactive oxygen species (ROS) and loss of insulin. Monozygotic twin studies show a 20-60% concordance with T1D indicating there may be an environmental component to the disease. Glutathione (GSH) is the major endogenous antioxidant produced b

Hexameric arginine repressor, ArgR, bound to L-arginine serves both as the master transcriptional repressor/activator at diverse regulons in a wide range of bacteria and as a required cofactor for resolution of ColE1 plasmid multimers. Multifunctional ArgR is thus unusual in possessing features of specific gene regulators, global regulators, and non-specific gene organizers; its closest functional
