Objectives. The prevalence of obesity is increasing. Overweight and obese people have increased mortality compared with normal weight people. We investigated the effect of weight change on mortality. Design. Prospective population study. Setting. We utilized data from two large population-based health studies conducted in 1984-86 and 1995-97 respectively. Cox proportional hazards models were used
Typical bogs in boreal forest zone can be characterized by hummock and hollow micro-topography and sparsely vegetated surfaces, thus, are quite distinct from other types of wetlands. Micrometeorological measurements were carried out in central Sweden at two bogs in different summer seasons. The data analysis aimed at obtaining good estimates for the roughness length z(ou) and the kB(-1) factor. Th
Infrared spectra from 25 to 4000 cm(-1) have been recorded of water (H2O, D2O and (H2O)-O-18) matrix isolated in neon, argon, and krypton matrices. Intermolecular absorption bands of different isotopologues of the water trimer and tetramer have been assigned from concentration dependencies and diffusion behavior, using the well-known mid-infrared trimer and tetramer absorption bands as measures of
The pelvic nerve, carrying parasympathetic nerve fibres, distributes bilaterally in the rat urinary bladder. Preganglionic parasympathetic denervation (decentralization) on one side and postganglionic parasympathetic denervation on the other are followed by an initial decrease in acetylcholine forming capacity and in number of acetylcholinesterase positive nerves in the bladder. However, within a
BACKGROUND: Co-morbidity with substance use disorders negatively influences overall functioning in patients with psychosis. However, frequencies and courses of risky use of alcohol, drugs and cigarettes are rarely investigated in patients at psychosis units.The purpose of this study is to describe the use of alcohol, drugs and cigarettes in patients at a psychosis unit over a 1 1/2 year period aft
This article presents a new method for conjugate view activity quantification for 131I-labeled monoclonal antibody distribution. METHODS: The method is based on the combined use of images from 3 modalities: whole-body (WB) scintillation camera scanning, WB transmission scanning using 57Co, and CT. All images are coaligned using a recently developed program for the registration of WB images. Correc
The biologic evaluation in living rats of 68Ga-labeled oligonucleotides as imaging agents for PET is reported. Methods: 68Ga, a positron-emitting radionuclide (half-life, 68 min), along with a macrocyclic chelating agent, 1,4,7,10-tetraazacyclododecane-N,N',N'',N'''-tetraacetic acid (DOTA), was used for labeling of antisense oligonucleotides targeting activated human K-ras oncogene. The biologic p
The hydrophobic interaction between two methane molecules in salt-free and high salt-containing aqueous solutions and the structure in such solutions have been investigated using an atomistic model solved by Monte Carlo simulations. Monovalent salt representing NaCl and divalent salt with the same nonelectrostatic properties as the monovalent salt have been used to examine the influence of the val
Popular Abstract in Swedish Avstår barn i fattiga länder från utbildning framförallt för att de är fattiga eller för att de upplever att skolan inte har något meningsfullt att erbjuda? Svaret på den frågan har stor betydelse för vilken politik som bör föras. Ett empiriskt bidrag till en sådan frågeställning är i vilken utsträckning som utbildning kan tänkas vara ett ?lönsamt? alternativ för indiviWhy do some children in the developing world choose to stay out of school? Is it mainly because poverty leaves them with no options or because schooling seems to offer them few benefits? The answers to these questions have profound policy implications. An empirical input into this discussion is the extent to which schooling can actually be perceived as a profitable option in various countries and,
In this time-course study the levels of different reactive species, especially those of nitric oxide and peroxynitrite were determined in streptozotocin-induced diabetic rat tissues at different time-points after the onset of the disease, before the development of histopathological damages. Significantly higher steady state free radical concentrations were found in the liver 3 weeks after the onse
In this paper, two new simple residual-based panel data tests are proposed for the null of no cointegration. The tests are simple because they do not require any correction for the temporal dependencies of the data. Yet they are able to accommodate individual specific short-run dynamics, individual specific intercept and trend terms, and individual specific slope parameters. The limiting distribut
Glutathione, the most abundant low-molecular weight thiol in the skin, has been shown to protect the skin from both photobiological and chemical injury. The thiols, glutathione in particular, have also been shown to be crucially involved in defence against contact allergens. Since the levels of extracellular thiol concentrations are important determinants of intracellular thiol status, we have com
