Stereological assessment of vulnerability of immunocytochemically identified striatal and hippocampal neurons after global cerebral ischemia in rats

Detailed quantitative analysis of the vulnerability of different hippocampal and striatal neurons to global forebrain ischemia has not previously been performed. Here we have studied the survival of immunocytochemically identified neurons using an unbiased stereological method in rats subjected to global forebrain ischemia for 30 min and sacrificed 48 h, 1 week or 4 weeks thereafter. Within the hi

A new fast-melting oral formulation of desmopressin: a pharmacodynamic study in children with primary nocturnal enuresis

Objective To determine the pharmacodynamic properties of a new oral lyophilisate formulation of desmopressin (in single doses of 30, 60, 120, 240, 360 or 480 mu g) in children with known primary nocturnal enuresis (PNE) and thus identify those dosages that could provide a duration of action corresponding to a typical length of night-time sleep in children with PNE; additional objectives were to de

An experimental and modeling study of propene oxidation. Part 2: Ignition delay time and flame speed measurements

Experimental data obtained in this study (Part II) complement the speciation data presented in Part I, but also offer a basis for extensive facility cross-comparisons for both experimental ignition delay time (IDT) and laminar flame speed (LFS) observables. To improve our understanding of the ignition characteristics of propene, a series of IDT experiments were performed in six different shock tub

Experimental Investigation of Laminar Flame Speeds for Medium Calorific Gas with Various Amounts of Hydrogen and Carbon Monoxide Content at Gas Turbine Temperatures

It is expected that, in the future, gas turbines will be operated on gaseous fuels currently unutilized. The ability to predict the range of feasible fuels, and the extent to which existing turbines must be modified to accommodate these fuels, rests on the nature of these fuels in the combustion environment. Understanding the combustion behavior is aided by investigation of syngases of similar com

Background Anastomotic leak is one of the most serious complications following bariatric laparoscopic Roux-en-Y gastric bypass (LRYGB), and associated with high morbidity rates and prolonged hospital stay. Timely management is of utmost importance for the clinical outcome. This study evaluated the approach to suspected leakage in a high-volume bariatric surgery unit. Methods All consecutive

Clinical expressions of juvenile hereditary retinal degenerations and macular dystrophies: Electrophysiological and genetic studies

Popular Abstract in Swedish Ärftliga näthinnesjukdomar med tidig debut Elektrofysiologiska och genetiska studier Ärftliga näthinnesjukdomar är den vanligaste orsaken till allvarligt synhandikapp hos unga människor i dagens Sverige. De flesta av dessa sjukdomar kan ännu inte behandlas, men vi har under de senaste åren fått allt större insikt i de bakomliggande sjukdomsmekanismerna, tack vare att Hereditary retinal degenerations are the most frequent reason for severe visual handicap among young people in Scandinavia today. In the six papers included in this thesis the phenotypic expressions, with emphasis on the electrophysiological findings, of five different juvenile hereditary retinal degenerations are described. The diagnoses have been confirmed by genetic analysis. The retinal disord

The evaporative gas turbine pilot plant (EvGT) has been in operation at Lund Institute of Technology in Sweden since 1997. This article presents the latest development in the evaporative technology, the evaporation of bio-ethanol in a gas turbine power plant as a means to reduce the emission of greenhouse gases. Bio-ethanol is produced from a feedstock consisting of corn-stover, and the bio-ethano

Risk factors for Clostridium difficile toxin-positive diarrhea: a population-based prospective case-control study

Increased incidence and severity of Clostridium difficile infections (CDIs) is of major concern. However, by minimizing known risk factors, the incidence can be decreased. The aim of this investigation was to calculate the incidence and assess risk factors for CDI in our population. A 1-year prospective population-based nationwide study in Iceland of CDIs was carried out. For risk factor evaluatio

Exercise in Youth and Long-Term Effects on Bone and Joints

Popular Abstract in Swedish Osteoporos (benskörhet) är ett tillstånd som definieras av låg benmassa och ett tillstånd som ökar med stigande ålder. Sjukdomen i sig är symptomfri men ökar risken för frakturer. Frakturer i kota, axel, handled, bäcken, och höft efter 50 års ålder är ofta förknippade med osteoporos och ca 70 000 sådana frakturer inträffar årligen i Sverige. Även artros (ledsvikt) i höfPartly due to an ageing population, the number of osteoporosis-related fractures and osteoarthritis (OA)-related hip and knee arthroplasty procedures is increasing. The individual suffering and the burden on society for these conditions is immense. Genetic contribution for the variance in bone mineral density (BMD) is estimated at around 60–80%, and for OA 50%, leaving a considerable proportion to

Intratumour diversity of chromosome copy numbers in neuroblastoma mediated by on-going chromosome loss from a polyploid state.

Neuroblastomas (NBs) are tumours of the sympathetic nervous system accounting for 8-10% of paediatric cancers. NBs exhibit extensive intertumour genetic heterogeneity, but their extent of intratumour genetic diversity has remained unexplored. We aimed to assess intratumour genetic variation in NBs with a focus on whole chromosome changes and their underlying mechanism. Allelic ratios obtained by S

Metabolic characteristics of prehypertension: role of classification criteria and gender

Objective We tested whether men and women in the European Society of Hypertension (ESH) high normal and normal blood pressure (BP) categories, all included in the the Seventh Joint National Committee (JNC 7) prehypertension group, share similar metabolic characteristics and whether they differ from men and women with optimal BP (<120/80 mmHg). Methods BP (multiple measurements with a standardized

The association between socioeconomic position, use of revascularization procedures and five-year survival after recovery from acute myocardial infarction

Background: Patients living under better socioeconomic circumstances often receive more active treatments after an acute myocardial infarction ( AMI) compared to less affluent patients. However, most previous studies were performed in countries with less comprehensive coverage for medical services. In this Swedish nation- wide longitudinal study we wanted to evaluate long- term survival after AMI

High Familial Risk of Atrial Fibrillation/Atrial Flutter in Multiplex Families: A Nationwide Family Study in Sweden

Background-Although the heritability of atrial fibrillation/atrial flutter (AF/AFl) has been determined, the familial risk in multiplex families is unclear. The main aim of this nationwide study was to determine the familial risk of AF/AFl in multiplex families. Methods and Results-We examined the familial risk of AF/AFl in the entire Swedish population. We linked Multigeneration Register data on

Oral contraceptives and postmenopausal hormones and risk of contralateral breast cancer among BRCA1 and BRCA2 mutation carriers and noncarriers: the WECARE Study

The potential effects of oral contraceptive (OC) and postmenopausal hormone (PMH) use are not well understood among BRCA1 or BRCA2 (BRCA1/2) deleterious mutation carriers with a history of breast cancer. We investigated the association between OC and PMH use and risk of contralateral breast cancer (CBC) in the WECARE (Women's Environment, Cancer, and Radiation Epidemiology) Study. The WECARE Study

A set-up for field studies of respiratory tract deposition of fine and ultrafine particles in humans

Respiratory tract deposition data of ultrafine aerosol particles, hygroscopic particles and ambient particles in general are scarce. Measurements are associated with several difficulties. The objective of this work was to design a method for fast determination of highly size-resolved fine and ultrafine particle deposition, to be used on larger groups of human subjects in exposure studies and in ty

Antigen and epitope specificity of anti-glomerular basement membrane antibodies in patients with Goodpasture disease with or without anti-neutrophil cytoplasmic antibodies

Goodpasture disease (GP) is defined by the presence of anti-glomerular basement membrane (anti-GBM) antibodies and rapidly progressive glomerulonephritis. Besides anti-GBM, many patients with GP produce anti-neutrophil cytoplasmic antibodies (ANCA). For elucidation of the pathophysiologic significance of ANCA in this setting, epitope and antigen specificity of the anti-GBM antibodies and antigen s
