We examined the localization of oestrogen receptor (ER) β mRNA in the human endometrium throughout the menstrual cycle using non-radioactive in-situ hybridization with Brigati-tailed oligonucleotides. The findings were compared with those of ERα in order to examine the possible biological significance of ERβ in the human endometrium. Both ERα and ERβ mRNA expression were detected in all major h...

The medicinal plant Xanthium strumarium L. (X. strumarium) is covered with glandular trichomes, which are the sites for synthesizing pharmacologically active terpenoids such as xanthatin. MicroRNAs (miRNAs) are a class of 21-24 nucleotide (nt) non-coding RNAs, most of which are identified as regulators of plant growth development. Identification of miRNAs involved in the biosynthesis of plant s...

BACKGROUND: Gastric ulcer is one of the most common diseases in racehorses. Colic, weight loss and poor performance are some of the clinical signs. The second and third larval stages of the bot fly Gasterophilus spp live in the stomach of the horse. This parasite is often found in large numbers of horses in all of the countries. OBJECTIVES: The a...

Previously, p-methoxyphenol fed in the diet was found to be the most potent inhibitor of benzo(a)pyrene-induced neoplasia of the mouse forestomach of 18 phenols investigated. In the present study, the effects of p-methoxyphenol on the direct-acting carcinogen, beta-propiolactone (BPL), were determined. p-Methoxyphenol administered at 1 or 4 hr prior to BPL or fed in the diet markedly inhibited ...

To ensure the maintenance of tissues in mammals, cell loss must be balanced with cell production, the proliferative activity being different from tissue to tissue. In this article, the authors propose a new method for the quantification of the proliferative activity, defined as the S-phase fraction of actively cycling cells, by dual labeling with fluorescence and peroxidase immunohistochemistry...

The aim of the study was to evaluate the functional role of reticular contractions for digesta passage in sheep. Feed intake, mean retention time of fluid and plastic particles in the reticulo-rumen, rumen fluid volume, forestomach motility and particle size distribution in the faeces were determined in five rumen-fistulated sheep fed on hay ad libitum (Expt 1). The same variables were determin...

An immunohistochemical study was carried out on two types of dendritic immune cells, Langerhans cells and Thy-1-positive cells, in the epithelium of the forestomach of 1-, 2-, 3-, 4- and 8-week-old mice. Investigation focused on how both types of cells were distributed and might interact in the mucosal epithelium. Langerhans cells and Thy-1-positive dendritic cells appeared in mucosal epitheliu...
