Lateral electron transport in high-intensity laser-irradiated foils diagnosed by ion emission

An experimental investigation of lateral electron transport in thin metallic foil targets irradiated by ultraintense (>= 10(19) W/cm(2)) laser pulses is reported. Two-dimensional spatially resolved ion emission measurements are used to quantify electric-field generation resulting from electron transport. The measurement of large electric fields (similar to 0.1 TV/m) millimeters from the laser focu

Behavioral characterization of a unilateral 6-OHDA-lesion model of Parkinson's disease in mice.

Parkinson's disease (PD) is one of the most common neurodegenerative disorders. Several toxin-induced animals models simulate the motor deficits occurring in PD. Among them, the unilateral 6-hydroxydopamine (6-OHDA) model is frequently used in rats and has the advantage of presenting side-biased motor impairments. However, the behavioral consequences of a unilateral 6-OHDA-lesion have, so far, not

Epilation today: Physiology of the hair follicle and clinical photo-epilation

Despite the variations of length and type of hair (vellus or terminal), the growth of human hair in all body sites is cyclic. Phases of active hair growth, or anagen, are separated by periods of quiescence, or telogen. The duration of both phases varies greatly depending on the body site. Whether hairs are in anagen/telogen at the time of hair removal is important because only anagen hairs are par

Treatment with cyclosporin A during sensitization with trimellitic anhydride attenuates the airway responses to allergen challenge three weeks later

The present studies examined the effects of oral treatment with cyclosporin A, betamethasone or azelastine administered over the time of sensitization with trimellitic anhydride on allergen-induced airway responses, compared to those of control animals given corn oil alone. Drugs were given for 8 days. The animals were sensitized with trimellitic anhydride (0.1 ml of 0.3% w/v) in corn oil given in

Synthesis of dipeptide units of the D D configuration in aqueous media by enzymatic catalysis

Novel molecularly imprinted polymer systems utilizing 4-vinylpyridine and 1-vinylimidazole as functional monomers have been developed for enantioselective recognition of carboxylic and N-protected amino acids. Non-covalent interactions between the functional monomers and the template molecules were the source of the subsequent recognition sites in the resultant polymers. The capacity of the polyme

A qualitative study of women's experiences of home birth in Sweden.

Objective: to illuminate the experiences of women who have given birth at home. Methods: a descriptive design with a qualitative approach based on interviews with 12 women. The text was analysed using a phenomenological-hermeneutic method. Findings: giving birth at home meant preserved authority and autonomy whereby the women themselves ruled the situation. The women's experiences of giving birth

Organ damage in treated middle-aged hypertensives compared to normotensives: results from a cross-sectional study in general practice

BACKGROUND: High blood pressure contributes to organ damage. However, during the past two decades there have been great advances in the medical treatment of hypertension. Technical progress has also made it easier to visualize organ damage. Hence we found it of interest to examine heart, brain and retina in a group of middle-aged treated hypertensives, comparing the results with those from a group

X-linked agammaglobulinemia (XLA): A genetic tyrosine kinase (Btk) disease

X-linked agammaglobulinemia is a heritable immunodeficiency disease caused by a differentiation abnormality, resulting in the virtual absence of B lymphocytes and plasma cells, The affected gene encodes a cytoplasmic protein tyrosine kinase, Bruton's agammaglobulinemia tyrosine kinase, designated Btk, Btk and the other family members, Tec, Itk and Bmx, contain five regions, four of which are commo

A numerical study of methods to predict the capacity of multiple steel-timber dowel joints

In this study, two numerical methods are used to predict the load-bearing capacity of multiple steel-timber dowel joints loaded parallel to the grain. The aim was to show the possibility and the advantages of using numerical methods when designing multiple dowel-type joints.The results showed a good correlation to experimental results taken from the literature and to traditional joint calculations

Training eye movements: can training people where to look hinder the processing of fixated objects?

An experiment designed to test the effects of different forms of training in a visual-search-like task is reported. Observers were presented with a series of displays containing a central letter and a ring of peripheral characters, one of which was a digit. Odd digits (catch trials) required a space-bar response; even digits required a different response contingent on the identity of the central l

Regional specification of neurosphere cultures derived from subregions of the embryonic telencephalon.

We have studied the molecular specification of precursor cells in expanded neurosphere cultures derived from distinct subregions of the embryonic mouse telencephalon. These regionally derived cultures exhibited differential responses to the mitogens EGF and bFGF, suggesting that the precursors in these cultures were differentially specified as is the case in situ. To examine this further, cultures

Progressive alterations in the hypothalamic-pituitary-adrenal axis in the R6/2 transgenic mouse model of Huntington's disease

Huntington's disease (HD) is characterized by a triad of motor, psychiatric and cognitive symptoms. Although many of these symptoms are likely to be related to central nervous system pathology, others may be due to changes in peripheral tissues. The R6/2 mouse, a transgenic model of HD expressing exon 1 of the human HD gene, develops progressive alterations in the hypothalamic-pituitary-adrenal ax

Common variants in the TCF7L2 gene help to differentiate autoimmune from non-autoimmune diabetes in young (15-34 years) but not in middle-aged (40-59 years) diabetic patients.

AIMS/HYPOTHESIS: Type 1 diabetes in children is characterised by autoimmune destruction of pancreatic beta cells and the presence of certain risk genotypes. In adults the same situation is often referred to as latent autoimmune diabetes in adults (LADA). We tested whether genetic markers associated with type 1 or type 2 diabetes could help to discriminate between autoimmune and non-autoimmune diab
