To investigate whether rat hippocampal neurogenesis varies with strain and gender, the authors examined proliferating progenitor cells and their progeny in young male and female Sprague-Dawley (SD) and spontaneously hypertensive rats (SHR) using the thymidine analog bromodeoxyuridine (BrdU) combined with immunohistochemistry for the neuronal marker Calbindin D28k and glial fibrillary acidic protei
Interviews with 75 teenagers and young adults were performed to investigate how young people with dyslexia experienced school in terms of well-being, educational achievement, self-esteem, peer relations and belief in their future. Results from earlier studies suggest that secondary emotional problems are common. The first six grades in school were experienced by the interviewees as full of distres
The dimeric nonprenylated acylphloroglucinol semimyrtucommulone (6) was obtained from the leaves of. myrtle (Myrtus communis) as a 2:1 mixture of two rotamers. The known trimeric phloroglucinol myrtucommulone A (1) was also isolated and characterized spectroscopically as a silylated cyclized derivative (5). Myrtucommulone A showed significant antibacterial activity against multidrug-resistant (MDR
Calcareous soils are frequently characterized by the low bioavailability of plant nutrients. Consequently, many vascular plant species are unable to successfully colonize calcareous sites and the floristic composition of calcareous and acid silicate soils has been shown to differ markedly. The root exudation of oxalate and citrate has been suggested to play a pivotal role in same nutrient acquisit
The contribution of this paper is a time-frequency domain speech presence detection method that classifies power bins in the time-frequency domain as containing speech or not. An initial decision rule is based on ratios between optimally time-smoothed signal-plus-noise periodograms and weighted noise periodogram estimates, obtained from minimum statistics as proposed by Martin [1]. The initial dec
The high spin structures in Nb-86 are analyzed using the cranked Nilsson-Strutinsky model. Energy versus spin curves as well as deformations and electric transition quadrupole moments are considered. It is concluded that different single-particle parameters compared with the standard values lead to better agreement with recent experimental results.
gamma -carboxylated polypeptides were detected in the human kidney by immunohistochemistry with a monoclonal antibody (M3B) specific for gamma -carboxyglutamyl residues. An similar to 70-kDa gamma -carboxylated protein, subsequently identified as prothrombin, was isolated from the intracellular compartment of cultured human embryonic kidney (HEK293) cells by immunoaffinity chromatography on M3B-co
High-grade gliomas are one of the most aggressive human tumors with <1% of patients surviving 5 years after surgery. Immunotherapy could offer a possibility to eradicate remnant tumor cells after conventional therapy. Experimental immunotherapy can induce partial cure of established intracerebral tumors in several rodent models. One reason for the limited therapeutic effects could be immunosuppres

The immune and the detoxication systems of animals are characterized by allelic polymorphisms, which underlie individual differences in ability to combat assaults from pathogens and toxic compounds. Previous studies have shown that females may improve offspring survival by selecting mates on the basis of sexual ornaments and signals that honestly reveal health. In many cases the expression of thes
Ectomycorrhizal (EM) fungi are known to colonize minerals in forest soil, and in many laboratory experiments it has been confirmed that EM fungi stimulate dissolution of minerals such as apatite, biotite and feldspars. However, due to the low number of experiments performed in the field, and in forests with different soil fertilities, it is difficult to conclude whether this effect has any ecologi
Rapporten är en probleminventering av beständighetsproblem i samband med putsade fasader. I rapporten redovisas ett 10-tal typiska exempel på de vanligaste problemen, utan att diskutera skadeorsaker eller orsaksfrågor. Inventeringen avslutas med ett översiktligt forskningsprogram med inriktning på sprickbildning i puts på isolering och missfärgning av mineraliska ytskikt.

The influence of continuous inhalation of 150 ppm trichloroethylene (TCE) on body, liver, spleen, and kidney weights in rats, mice, and mongolian gerbils was tested. An age dependent decrease in body weight gain was observed in female rats exposed to TCE. All 3 spcies showed liver enlargement caused by the exposure. The effect was much more pronounced in mice, in which the increase was 60–80%, th
