Trauma to a peripheral nerve trunk is a complex injury because it involves not only repair processes locally at the peripheral level, but it also engages repair and compensation mechanisms at central levels. The main actor is the fascinating and unique neuron with its supporting cells, which consist mainly of Schwann cells. In the neuron and in the Schwann cells, intracellular signaling mechanisms
By a mixture density is meant a density of the form pi(mu) (.) = f pi(theta) (.) x mu(d theta), where (pi(theta))(theta Theta is an element of) is a family of probability densities and mu is a probability measure on Theta. We consider the problem of identifying the unknown part of this model, the mixing distribution A, from a finite sample of independent observations from pi(mu). Assuming that the
BACKGROUND: To investigate which factors during gestational diabetes pregnancies correlate with the risk of developing impaired glucose tolerance or diabetes 1 year postpartum and to compare this risk in women with gestational diabetes and women with a normal oral glucose tolerance test during pregnancy. METHODS: Of 315 women with gestational diabetes, defined as a 2-hr blood glucose value of at l
The weak D phenotype is the most common D variant, with a frequency of 0.2-1% in Caucasian individuals. There are several weak D types, with different frequencies in European countries, which may pose serologic problems and have the potential for alloimmunization. Samples from Portuguese individuals were tested for RhD by two or three distinct monoclonal and oligoclonal antisera, in direct aggluti
Abstract: Previous experiments have shown that severe hypoglycemia disrupts cerebral energy state in spite of a maintained cerebral oxygen consumption, suggesting uncoupling of oxidative phosphorylation. Other studies have demonstrated that hypoglycemia leads to loss of cerebral cortical phospholipids and phospholipid-bound fatty acids. The objective of the present study was, therefore, to study r
This study has focused on structures formed through the release of lipid membrane material from milk fat globules. The aim of the study was to describe vesicles in the cream plasma and processing-induced vesicular structures in cream and buttermilk. The dairy samples were divided into three fractions through centrifugation, using DO for density control. These fractions were examined using cryogeni
We examined temporal and geographical distribution of Haemoproteus sp. and Plasmodium sp. parasites in Swedish willow warblers, Phylloscopus trochilus. Parasite lineages were detected with molecular methods in 556 birds from 41 sites distributed at distances up to 1,500 km. Two mitochondrial lineages of Haemoproteus sp. were detected, WW1 in 56 birds and WW2 in 75 birds, that differed by 5.2% sequ
The gamma-decay of excited states in the neutron deficient isotopes Tc-87 and Tc-88 has been observed for the first time. The fusion-evaporation reactions Ni-58(S-32, p2n)Tc-87 and Ni-58(S-32, pn)Tc-88 at 110 MeV, Ca-40(Cr-50, p2n)Tc-87 and Ca-40(Cr-50, pn)Tc-88 at 170 MeV and Ni-58(Ar-36, alpha-pn)Tc-88 at 145 MeV beam energy were used. Unambiguous identification of these nuclei which are populat
The adapter protein APS has previously been shown to be involved in recruiting the ubiquitin E3 ligase c-Cbl to the insulin receptor, the platelet-derived growth factor b-receptor and the erythropoietin receptor, leading to increased degradation of the receptors and inhibition of mitogenesis. Here we demonstrate, by use of immobilized synthetic phosphopeptides corresponding to various autophosphor
Popular Abstract in Swedish Barns villkor i stadsmiljö är ett viktigt tema för förståelsen av den moderna barndomen. Barn har emellertid sällan tillfrågats om sin syn på stadens miljövillkor. Avhandlingens syfte är sammanfattningsvis: * Att beskriva de sakkunnigas försök att skapa goda uppväxtvillkor för barn i stadsmiljö, utifrån det jag sammanfattande benämner "de för barnen tänkta perspektivenChildren's conditions in urban environments are an important theme for understanding modern childhood, yet children have rarely been asked about their views of urban childhood conditions. The aim of the dissertation is: To describe the experts' attempts to create good conditions for growing up in an urban environment. This is summed up as "perspectives thought out for the children". To investiga
Objective: Hypoxic-ischemic encephalopathy (HIE) is one of the major causes of perinatal mortality and morbidity. To date, there are no reliable methods to detect which infants will develop brain damage after asphyxia insult. Design and Setting: Prospective study conducted in three tertiary departments of neonatology from December 1999 to July 2002. Participants: A total of 44 infants with perinat
Popular Abstract in Swedish Olika laserbaserade mätmetoder för diagnostik av förbränningsmotorrelaterade fenomen har utvecklats och demonstrerats, såväl utanför som i motorer. Följande områden har studerats: -Inverkan av inhomogen bränsle-/luftblandning på cykel-till-cykelvariationer hos förbränningen i en otto-motor studerad genom laserinducerad fluorescens (LIF) på bränslet. -Restgasers inverkanVarious laser diagnostic techniques have been developed and demonstrated for engine, or engine-related measurements. The experimental work is presented in Chapter 3 and in Papers I-VII. In Chapter 3, imaging of soot in a running compression-ignition (CI) is described. Four different approaches were applied with the aim of investigating the applicability of these approaches in a running engine. I
OBJECTIVES: To explore the development of hypertension (HT) in a cohort of young middle-aged men. DESIGN: Prospective birth-cohort study of men surveyed over 6 years. SETTING: Helsingborg County Hospital, Sweden, 1990-97. SUBJECTS: A total of 628 men born in 1953-54, all surveyed at 37, 40 and 43 years of age.

OBJECTIVE: To compare the outcome of patients operated on acutely for ruptured abdominal aortic aneurysms (AAA) or otherwise symptomatic aortic aneurysms in a university hospital and in two county hospitals by the same group of vascular surgeons. DESIGN: Retrospective study. SETTING: 1 university and 2 county hospitals, Sweden. SUBJECTS: 108 patients operated on urgently for AAA, 81 at the univers
