Maternofetal pathogen transmission is partially controlled at the level of the maternal uterine mucosa at the fetal implantation site (the decidua basalis), where maternal and fetal cells are in close contact. Toll-like receptors (TLRs) may play an important role in initiating rapid immune responses against pathogens in the decidua basalis, however the tolerant microenvironment should be preser...

BACKGROUND AND PURPOSE For a better understanding of neuronal network disturbances after stroke, we investigated the changes in the cholinergic system after experimental focal infarct. METHODS We quantitatively evaluated the highly sensitive acetylcholinesterase histochemistry and local glucose utilization 7 days after left middle cerebral artery occlusion in Wistar rats. RESULTS In all rat...

The number of nerve cells in the nucleus basalis of Meynert in normally aged persons is reduced by 30% by 90 years of age and cytoplasmic RNA content and nucleolar volume by about 20%. In Alzheimer's disease the changes are greatly exacerbated, with the cell number being depleted by a further 60% and cytoplasmic RNA content and nucleolar volume by an extra 35%. Moreover, younger patients with A...

The genus name Limnobaris Bedel is applied in a restricted sense to baridine weevils with a covered pygidium and non-prominent, decussate mandibles which occur on sedges in the Palaearctic Region and immediately adjacent parts of tropical Southeast Asia. Calyptopygus Marshall and Pertorcus Voss are syn. n. of Limnobaris. Some species from Africa and the Americas are maintained provisionally in ...

Objective: The presence of nerve fibers in human endometrium remains unsettled but recent immunocytochemical studies have shown that there was increased innervation in the endometrium from women with endometriosis and some nerve fibers in the normally cycling human endometrium. In the current study, we used uterine tissue cryosections from normal cycling women, which previously provided better ...

The present study reports for the first time the distribution of androgen receptor immunoreactivity (AR-ir) in the human hypothalamus of ten human subjects (five men and five women) ranging in age between 20 years and 39 years using the antibody PG21. Prolonged postmortem delay (72:00 hours) or fixation time (100 days) did not influence the AR-ir. In men, intense nuclear AR-ir was found in neur...

Sperm quantity and quality during storage may be constraints acting on female fecundity and hence fitness. In Hymenoptera, the importance of sperm quality has rarely been considered, despite its central role in reproductive strategies and especially in sex ratio control. In these insects, fertilized eggs develop into females and unfertilized eggs into males. Experiments were conducted on the fe...

Background—The cholinergic nucleus basalis (Ch4) is an exclusive site of neurofibrillary degeneration in alcoholic patients with Wernicke’s encephalopathy. Aim—To test the hypothesis that the loss of Ch4 neurons contributes to thememory disorder, KorsakoV’s psychosis, commonly seen in Wernicke’s encephalopathy. Methods—Magnocellular basal forebrain neurons were quantified in alcoholic patients ...
