Eosinophils are a characteristic component of the inflammatory response seen in several diseases, including allergic asthma and chronic obstructive pulmonary disease. After activation, eosinophil-derived products may exert proinflammatory effects and cause considerable tissue damage. In the present study, we investigated innate interactions between the respiratory tract pathogen nontypeable Haemop
When several individuals simultaneously provide for offspring, as in families, the effort of any one individual will depend on the efforts of the other family members. This conflict of interest among family members is made more complicated by their relatedness because relatives share genetic interest to some degree. The conflict resolution will also be influenced by the differences in reproductive
INTRODUCTION: Competitive breath-hold divers can accomplish previously unbelievable performances; e.g., the current world record for apnea during rest ("static apnea") is 11 min 35 s. However, whether such performances are associated with a risk for hypoxic brain damage has not been established. CASE REPORT: A breath-hold diver's competitive performance resulted in a loss of consciousness, after w
Paxillus involutus (basidiomycetes, Boletales) is a common ectomycorrhizal fungus in the Northern Hemisphere. The fungus displays significant variation in phenotypic characters related to morphology, physiology, and ecology. Previous studies have shown that P. involutus contains several intersterility groups and morphological species. In this study, we have used concordance of multiple gene geneal
Routine infusions of factor VIII to prevent bleeding, known as prophylaxis, and other intensive therapies are being more broadly applied to patients with haemophilia. These therapies differ widely in replacement product usage, cost, frequency of venous access and parental effort. In order to address residual issues relating to recommendations, implementation, and evaluations of prophylaxis therapy
The apolipoprotein (apo) A-I:B ratio and the apo B concentration were determined by radial immunodiffusion in dried blood spot samples from 1,767 10- and 11-year-old children. Children with either apo A-I:B ratios below the first percentile or apo B levels above the 99th were recalled and plasma lipid and apolipoprotein profiles were determined for both children and parents. Of 17 children (one fa
In addition to fermentable sugars, dilute-acid hydrolysates of lignocellulose contain compounds that inhibit fermenting microorganisms, such as Saccharomyces cerevisiae. Previous results show that phenolic compounds and furan aldehydes, and to some extent aliphatic acids, act as inhibitors during fermentation of dilute-acid hydrolysates of spruce. Treatment of lignocellulose hydrolysates with alka
The transport rate of polychlorinated biphenyls (PCBs) from water to air was followed in a large (50-m3) artificial pond. The transport rate across the water/air interface during the day exceeded the rate at night and was positively correlated to air temperature. Volatilization is probably responsible for the PCB transfer.
This article examines the origin, development, and characteristics of the indigenous psychologies (IPs) initiated in various regions of the world. These IPs arose as a reaction to the mainstream version of psychology and seek to reflect the social, political, and cultural character of peoples around the world. Fifteen contributions from researchers from different parts of the world are presented,
In order to investigate potential selection bias in population-based cohort studies, participants (n = 28098) and non-participants (n = 40807) in the Malmo Diet and Cancer Study (MDCS) were compared with regard to cancer incidence and mortality. MDCS participants were also compared with participants in a mailed health survey with regard to subjective health, socio-demographic characteristics and l
The leukocyte response in inflammation is characterized by an initial recruitment of polymorphonuclear leukocytes (PMN) preceding a second wave of monocytes to the site of injury or infection. In the mouse, 2 populations of monocytes have been identified, Gr1-CCR2-CX3CR1(hi) resident monocytes and Gr1+CCR2+CX3CR1(lo) inflammatory monocytes. Here, intravital microscopy of the musculus cremasterand
Generating proteomic maps of membrane proteins, common targets for therapeutic interventions and disease diagnostics, has turned out to be a major challenge. Antibody-based microarrays are among the novel rapidly evolving proteomic technologies that may enable global proteome analysis to be performed. Here, we have designed the first generation of a scaleable human recombinant scFv antibody microa
A consortium consisting of a Chlorella sorokiniana strain and a Ralstonia basilensis strain was able to carry out sodium salicylate biodegradation in a continuous stirred tank reactor (CSTR) using exclusively photosynthetic oxygenation. Salicylate biodegradation depended on algal activity, which itself was a function of microalgal concentration, light intensity, and temperature. Biomass recirculat
The interaction of DNA with amino-functionalized polystyrene particles has been studied by using a dynamic light scattering (DLS) technique. In 10 mM NaBr solution the particles have a hydrodynamic radius of 76 nm and the DNA macromolecule investigated (double stranded) has a hydrodynamic radius of 107 nm. At very low DNA concentrations, DNA adopts a flat conformation on the particle surface. If t
We investigate resonant tunneling through two coupled self-assembled quantum dots. The strong confinement and the high crystalline quality provided by the self-assembled dots, in combination with the tunneling coupling between the dots, create a system that may be thought of as an artificial molecule. We are able to isolate one single artificial molecule and detailed investigations of the electric
Study objective: Previous research provides preliminary evidence of spatial variations of mental disorders and associations between neighbourhood social context and mental health. This study expands past literature by (1) using spatial techniques, rather than multilevel models, to compare the spatial distributions of two groups of mental disorders (that is, disorders due to psychoactive substance
BACKGROUND: Increased pulmonary vascular resistance is frequently seen after lung transplantation. Thromboxane A2 is a potent vasoconstrictor of pulmonary arteries. Thromboxane-elicited vasoconstriction can ben counteracted by prostacyclin. The effects of lung transplantation on the biosynthesis of these substances were investigated. METHODS: Pulmonary artery flush perfusion with a low-potassium d
During the last decade, identification of the genes involved in familial forms of Parkinson's disease (PD) has advanced our understanding of the mechanisms underlying the development of different aspects of PD. However the available animal models still remain as the main limiting factor for the development of neuroprotective therapies that can halt the progression of the disease, through which we
