Huntington’s disease (HD) is a neurodegenerative disorder caused by expansion of a polyglutamine tract in a protein called huntingtin. The inducible form of heat shock protein 70 (Hsp70) has been shown to reduce polyglutamine-induced toxicity. To investigate if overexpression of Hsp70 can affect disease progression in a mouse model of HD, we crossed R6/2 mice, expressing exon 1 of the HD gene with

The influence of the severity of dilute sulfuric acid hydrolysis of spruce (softwood) on sugar yield and on the fermentability of the hydrolysate by Saccharomyces cerevisiae (Baker's yeast) was investigated. Fermentability was assessed as the ethanol yield on fermentable sugars (mannose and glucose) and the mean volumetric productivity (4 h). The hydrolysis conditions, residence time, temperature,

Introduction: Identification of suitable candidates for cardioversion currently is not based on individual electrical and mechanical atrial remodeling. Therefore, this study analyzed the meaning of atrial fibrillatory rate obtained from the surface ECG (as a measure of electrical remodeling) and left atrial size (as measure of mechanical remodeling) for prediction of early atrial fibrillation (AF)

Secretory type 2 cystatins, like cystatins C, E/M and F, are thought to be involved in many pathobiological processes, including vascular amyloidosis, rheumatoid arthritis, Alzheimers disease, osteoporosis, viral and bacterial infections, inflammatory disorders and tumour invasion and metastasis. In order to define the levels of cystatins C, E/M, and F in pleural effusions and to investigate wheth

We have fabricated InAs dots on the surface of InP, determined their structure, and measured the optical transition energy. This energy was found to be in excellent agreement with theoretical calculations, where no free parameters have been used. The calculations were performed using eight-band k center dot p theory in the envelope function approximation. We conclude that this theory is adequate t

The sensitivity to frost in the living inner bark of trees have been hypothesised to be influenced by acid rain and N deposition through changes in nutrient balance and carbon metabolism. At the Skogaby experimental site, situated in southern Sweden, Norway spruce in control plots, plots fertilized with ammonium sulphate and plots fertilized with mineral nutrients except N were compared in this re

To explore attitudes toward female genital cutting (FGC) in a migration perspective, qualitative interviews were conducted with men and women from Ethiopia and Eritrea in Sweden. We found firm rejection of all forms of FGC and absence of a guiding motive. Informants failed to see any meaning in upholding the custom. We conclude that children of Ethiopian or Eritrean parents resident in Sweden run

A series of experiments were conducted to address the fate of dissolved organic carbon (DOC) in the peat - stream interface zone linking a minerotrophic poor fen and an ombrotrophic mire with surrounding stream water in the drainage area of Lake Ortrasket in northern Sweden. Transport and mineralisation of DOC were quantified in peat - stream interface cores in response to variations in pore water

The enduring cognitive deficits and histopathology associated with traumatic brain injury (TBI) may arise from damage to mitochondrial populations, which initiates the metabolic dysfunction observed in clinical and experimental TBI. The anecdotal evidence for in vivo structural damage to mitochondria corroborates metabolic and physiologic dysfunction, which depletes substrates and promotes free ra

Streptococcus pneumoniae (pneumococcus) is a major cause of morbidity and mortality world-wide. The initial event in invasive pneumococcal disease is the attachment of encapsulated pneumococci to epithelial cells in the upper respiratory tract. This work provides evidence that initial bacterial adhesion and subsequent ability to cause invasive disease is enhanced by pili, long organelles able to e

This paper develops a (QP and a) DP analysis of the Icelandic NP, dealing primarily with prenominal modifiers and postnominal genitives. The paper argues that prenominal quantifiers and determiners head their own projections(QP and DP), whereas attributive adjectives are head-adjoined to nouns. In addition, it is suggested that the minimal NP in morphological case languages, such as Icelandic and

We have made use of a reporter mouse line in which enhanced green fluorescence protein (GFP) is inserted into the Sox1 locus. We show that the GFP reporter is coexpressed with the Sox1 protein as well as with other known markers for neural stem and progenitor cells, and can be used to identify and isolate these cells by fluorescence-activated cell sorting (FACS) from the developing or adult brain

The effect of viruses on the microbial loop, with particular emphasis on bacteria, was investigated over an annual cycle in 2003–2004 in Lake Druzhby and Crooked Lake, two large ultraoligotrophic freshwater lakes in the Vestfold Hills, Eastern Antarctica. Viral abundance ranged from 0.16 to 1.56 × 109 particles L-1;1 and bacterial abundances ranged from 0.10 to 0.24 × 109 cells L-1;1, with the low

The objective of the study was to investigate bone mineral density and bone turnover among female students aged 16-24 years in relation to lifestyle factors, such as dietary habits and physical activity, as well as physiological factors, such as age, body weight, and menstrual pattern. Female college and university students (n = 218) were given a validated questionnaire with 34 questions concernin

Studies, mainly from the UK, show that many farmland birds have declined as a result of recent agricultural intensification. We tested this idea by analysing farmland bird population trends in Sweden, a country displaying less dramatic agricultural changes and less intensive agriculture. Specifically we investigated whether (i) farmland specialists have declined more than generalists, (ii) populat
