The formation of adducts between methyltetrahydrophthalic anhydride (MTHPA), an important industrial chemical and potent allergen, and collagen from guinea pig lung tissue was investigated. Collagen peptides were obtained from the lung tissue by homogenization, defatting, washing, and digestion with collagenase. In experiments in vitro, lung tissue was exposed to 8.4 mumol (50 microCi) of 14C MTHP
The ordinary differential equations given by Ljung(1977) are used to analyse the behaviour of a certain adaptive extremal controller. It is shown that this controller will usually converge to the wrong point.This work was supported by the Swedish Board for Technical Development under contract No. 76-3804.
OBJECTIVE: To determine the intraobserver repeatability of Doppler measurements of uterine artery blood flow velocity and the contribution of various factors to within-subject variance. DESIGN: Seventeen healthy premenopausal women underwent vaginal Doppler ultrasound examination of the uterine artery by the same observer. Three measurements were taken at each of three sites: 1) the currently reco
Kan sociologin användas till att förstå filosofiskt tänkande? De senaste decennierna har en ny typ av studie växt fram som studerar filosofiskt tänkande ur ett sociologiskt perspektiv. På engelska benämns denna desciplin sociology of philosophy respektive sociology of philosophical knowledge. En lämplig svensk översättning torde bli filosofisociologi. Filosofisociologisk forskning syftar till at
STUDY OBJECTIVE. To evaluate the effect of family therapy on childhood obesity. DESIGN. Clinical trial. One year follow-up. SETTING. Referral from school after screening. PARTICIPANTS. Of 1774 children (aged 10 to 11), screened for obesity, 44 obese children were divided into two treatment groups. In an untreated control group of 50 obese children, screened in the same manner, body mass index (BMI
Control design is often done based on simplified models. After design it is necessary to verify that the real closed loop system behaves well. This is mostly done by experiments and simulations. Theoretical analysis is an important complement to this that can help to verify critical cases. Structural information about uncertainties, time-variations, nonlinearities, and signals can be described by
This study investigates the toxic effect of E(2)nonenal (trans-2-nonenal, T2N) and its conjugate with horse muscle myoglobin (Mb) tested on murine cell line L929 and human cell line A549, as well as the genotoxic effect of these compounds assayed by measuring of micronuclei in human cells K562. It is an aldehyde, which is occurring as the substance responsible for an off flavour in aged beers, but
Background Earlier reports on reduced physical performance and osteoporosis-related fractures have mostly been short-term studies. The aim of this investigation was to examine the effects of fractures on physical functioning 3 years after trauma, the latter being stratified for pain. Participants and methods The study consisted of a population-based case-control study including 289 subjects from t
The prevalence of abdominal aortic aneurysm (AAA) in a defined population of elderly men and its correlation to some risk factors were studied in the population cohort "men born in 1914 from Malmo". A total of 499 were invited to attend and 375 (75%) did so. The aorta could be visualised with ultrasound in 364 patients, 39 (10.7%) of whom had aneurysmal changes. The presence of an AAA was related
Patients diagnosed with diffuse large B-cell lymphoma (DLBCL) show varying responses to conventional therapy, and this might be contributed to the differentiation stage of the tumor B-cells. The aim of the current study was to evaluate a panel of kinases (ZAP70, PKC-beta I and II and phosphorylated PKB/Akt) and phosphatases (PTEN, SHP1 and SHP2) known to be frequently deregulated in lymphoid malig
In Sweden a new red list was issued 2000, but there is no published list of the most important areas for biodiversity preservation. I use woodliving and red-listed beetles as indicators of “hot-spots” for biodiversity preservation, since these insects constitute a large proportion of the red-listed forest living species in Sweden. Based on museum and many large private collections of beetles from
