Some animal models have been used to study Alzheimer's disease (AD). AD is an irreversible progressive neurodegenerative disease and the most common cause of dementia. Animal studies have shown that there is a relation between decrease in cholinergic functions in the nucleus basalis of Meynert (NBM) and loss of learning capability and memory. The aim of this study was to investigate the effect ...

We relate the problem of computing the closure of a nitely generated subgroup of the free group in the pro-V topology, where V is a pseudovariety of nite groups, with an extension problem for inverse automata which can be stated as follows: given partial one-to-one maps on a nite set, can they be extended into permutations generating a group in V? The two problems are equivalent when V is exten...

A polysaccharide-rich substance isolated from black currant, named cassis polysaccharide (CAPS), was partially digested with beta-galactosidase from Aspergillus oryzae and its immunostimulatory activity was investigated. The in vitro cytokine-inducing effect of CAPS on RAW264 cells was gradually decreased along with lowering of the average MW of CAPS. In vivo, partially digested CAPS with a mea...

Adelognathus leucotrochi Shaw & Wahl sp. nov. is described from Britain where it is a univoltine slightly gregarious koinobiont ectoparasitoid of late stage larvae of the tenthredinid sawfly Nematus leucotrochus Hartig feeding on Ribes uva-crispa. Defensive reactions by the host to prospecting females are described. The developmental biology of A. leucotrochi is described in detail: the host is...

Herbal medicine has been used for the prevention and treatment of various health aliments from time immemorial. In the present work, embelin from Embelia ribes berries of Indian origin was extracted and characterized by UV, NMR, thermal and X-ray diffraction analyses. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of embelin against both Gram +ve and Gram -v...

The above statement may accurately represent the current situation but will very soon be out of date. The last 30 years has seen the emergence of the kiwifruit from being a small but increasing crop in one country to being a crop of worldwide significance. The next few years will see the entry of new and quite different Actinidia fruit into international trade. The kiwifruit (Actinidia delicios...

The first aim of this paper was to evaluate pesticide residue levels of berry fruit samples. The second aim was to analyze health risks associated with pesticide levels. The monitoring was conducted on samples from producers in north-eastern Poland, during the time period 2005-2010. In total, 241 samples of berry fruit were analyzed using validated and accredited multi residue methods. The stud...

The methanol and chloroform extracts of Boerhaavia diffusa were prepared and investigated for TLC. It was concluded that the chloroform extract showed the better results for TLC in solvent system toluene : acetone : acetic acid. The major spots and their RF values were calculated.
