The present investigation assessed the effects of 2-methyl-6-(phenylethynyl)-pyridine (MPEP) on acquisition and reference memory in the Morris water maze in young adult rats aged 3-month and old rats aged 26-month. MPEP reduced the swim speed of the young adult rats during acquisition, shortened the distance they covered and reduced their swim speed in the probe trial. The untreated old rats ha...

Determining the upper treeline is certainly one of the most interesting research challenges in comparative high mountain research. Careful compilations (Hermes 1955; von Wissmann 1961; Schickhoff 2005) have documented that the highest treelines in the northern hemisphere are found on the eastern declivity of the Tibetan Highlands. However, regional and global synopses of upper treeline altitude...

introduction: since discovery of high frequency waves, their biological effects have been in great attention. increased male fertility problems proposed their possible relation to use of microwaves. testes are of very active body tissues, which can be affected by these waves. age of exposure may also be an important factor. methods: this study was carried out to evaluated testosterone level in ...

Precision-cut liver slices (PCLS) offer a lot of advantages because all heterogeneity and cell-cell interactions within the original tissue matrix are maintained. This in vitro model was used to study the effect of ageing on certain aspects of drug metabolism and liver function in young (3 months), adult (9 months) and old (24 months) Wistar male rats. Protein synthesis, an important liver func...
