Forest protection is one of the main measures to prevent loss of biological and landscape diversity. This study aimed to assess to what extent forests are currently protected and how felling restrictions affect the potential annual wood supply within 27 European Union member states, Norway, and Switzerland and to discuss trade-offs between intensified use of forest biomass and forest protection ef

Poly-3-d-hydroxybutyrate (PHB) is a promising biopolymer naturally produced by several bacterial species. In the present study, the robust baker's yeast Saccharomyces cerevisiae was engineered to produce PHB from xylose, the main pentose found in lignocellulosic biomass. The PHB pathway genes from the well-characterized PHB producer Cupriavidus necator were introduced in recombinant S. cerevisiae

The genetic background of Growth Hormone (GH) secretion is not well understood. Mutations giving rise to a stop codon have a high likelihood of affecting protein function.

OBJECTIVE: The aim was to study effects on motor skills and self-esteem of an extension of the Swedish school subject Physical Education and Health (PEW and motor training during nine school years. DESIGN AND METHOD: An intervention group (n=161) had PEH and motor training five lessons (225 nun) and a matched control group (n=102) had regular PEH two lessons (90 min) per week. The method was hypot

This article considers the distributional consequences of seasonality by analysing the links between non-farm incomes, commercialisation within agriculture, and variations in consumption burdens and expenditures at the household level. The common focus in the literature on non-farm incomes as levellers of seasonality and sources of risk minimisation is complemented by perspectives which consider h

BACKGROUND: Hemostatic disorders are common in obstetric complications. Thromboelastography (TEG (R)) simultaneously measures coagulation and fibrinolysis within 10 to 20 minutes. Our primary aim in this prospective longitudinal study was to obtain knowledge about physiological changes in TEG (R) variables during normal pregnancy and 8 weeks postpartum. The secondary aims were to compare TEG (R) v

Drugs that selectively activate estrogen receptor beta (ER beta) are potentially safer than the nonselective estrogens currently used in hormonal replacement treatments that activate both ER beta and ER alpha. The selective ER beta agonist AC-186 was evaluated in a rat model of Parkinson's disease induced through bilateral 6-hydroxydopamine lesions of the substantia nigra. In this model, AC-186 pr

Objective: The home environment is a key determinant of health, quality of life, and well-being. Given its relevance for such aspects, the scarcity of evaluations of housing adaptation (HA) interventions aimed at removing environmental barriers and accessibility problems in the homes of people with disabilities is surprising. This article aims to contribute to the development of strategies for eco

This study investigated whether perfluorooctanoic acid (PFOA) and perfluorooctanesulfonate (PFOS), which exhibit reproductive toxicity in experimental animals, affect sperm sex chromosome ratio. The Y:X ratio was determined by fluorescence in situ hybridization. Serum concentrations of PFOA and PFOS were measured in 607 men from Greenland, Poland and Ukraine using liquid chromatography-tandem mass

In epidemiological and twin populations, prior interview studies have identified an externalizing spectrum of disorders. Could this be detected utilizing objective registry data? In 20,603 twin pairs from the Swedish Twin Registry, we obtained information from national medical, criminal and pharmacy records on drug abuse (DA), criminal behavior (CB) and alcohol use disorders (AUD). Multivariate tw

Very long chain primary alcohols are significant components in cuticle waxes of plants. Fatty acyl-CoA reductases (FARs) catalyze the formation of a fatty alcohol from an acyl-CoA. The Arabidopsis (Arabidopsis thaliana) genome contains eight genes homologous to FAR genes from jojoba (Simmondsia chinensis), silk moth, wheat and mouse. Expression of six Arabidopsis FAR homologs in Escherichia coli r

The diagnostic beam line at the MAX III synchrotron light source utilizes the synchrotron radiation (SR) in the visible to ultraviolet range to form images of the transverse electron beam profile. The emission and subsequent propagation and focusing of the SR is modeled, taking into account effects such as diffraction and the longitudinally distributed SR generation. A detailed description of the

The epimerization of glucuronic acid into iduronic acid adds structural variability to chondroitin/dermatan sulfate polysaccharides. Iduronic acid-containing domains play essential roles in processes such as coagulation, chemokine and morphogen modulation, collagen maturation, and neurite sprouting. Therefore, we generated and characterized, for the first time, mice deficient in dermatan sulfate e

Background: A varying response to cholinesterase inhibitor (ChEI) treatment has been reported among patients with Alzheimer's disease (AD). Whether the individual-specific response, specific ChEI agent or dose affects mortality is unclear. We aimed to examine the relationship between the 6-month response to ChEI and lifespan. Methods: Six hundred and eighty-one deceased patients with a clinical AD

The development of a ternary AlxIn1-xP shell grown around GaAs nanowires epitaxially grown in the [(1) over bar (1) over bar (1) over bar] direction has been studied. Morphology and composition of the shell have been studied using cross-sectional transmission electron microscopy (TEM). The side facets of the shell are found to develop dominant {1 (1) over bar 0} macro facets with small (approx. 5
