The aim of present study was to clarify the post-natal profile of follicle-stimulating hormone (FSH), luteinizing hormone (LH), immunoreactive (ir)-inhibin, progesterone, testosterone, and estradiol-17β, and their relationships in Thoroughbred colts. Six hundred and thirty-six colts were used for the study. Single plasma samples from each animal were harvested from the blood drawn through jugul...

INTRODUCTION It has been suggested that the application of penile-extender devices increases penile length and circumference. However, there are a few scientific studies in this field. AIMS The aim of this study was to assess the efficacy of a penile-extender (Golden Erect(®) , Ronas Tajhiz Teb, Tehran, Iran) in increasing penile size. METHODS This prospective study was performed on subject...

The aim of the study was to characterize a) the lipofuscin-like pigment (LFP) accumulation (an indicator of ROS production) in the rat heart during early postnatal period and b) possible antioxidative role of selenium. Experimental animals received Na(2)SeO(3) in drinking water during gravidity and up to day 15 post partum. Two fluorophores of LFP in the hearts of 1-, 4-, 7- and 15-day-old rats...

We present the results of pollen analysis performed on an ice core recovered from Nevado Sajama, Bolivia, dated to 25 ka BP. Low pollen concentrations from 25 to 15 ka BP are consistent with the scenario of an expanded ice cap surrounded by sparse vegetation and cold conditions on the Altiplano during the Last Glacial Maximum. After 15 ka BP, more pollen is present and percentages show vegetati...

An animal model that mimics progressive disseminated vaccinia was elaborated. To this end nude (athymic) mice were inoculated intracutaneously with vaccinia virus in the lumbosacral area. Viral replication (DNA) in the skin was detected as early as day 2 postinfection (p.i.). Mice developed typical vaccinia lesions at the site of inoculation by day 4 to 6 p.i. By about 2 weeks p.i., the infecti...

The first trimester of pregnancy starts with the first day of the last menstrual period (LMP) and continues until the end of the twelfth week. Although, conception normally occurs two weeks after the LMP, the LMP is chosen as the start of the first trimester because it is a recognizable sign for most women. The term menstrual age and gestational age are used interchangeably, but should not be c...

Abstract During dental treatments, intraoral appliances frequently induce traumatic ulcers in the oral mucosa. Such mucosal injury-induced mucositis leads to severe pain, resulting in poor quality of life and decreased cooperation in the therapy. To elucidate mucosal pain mechanisms, we developed a new rat model of intraoral wire-induced mucositis and investigated pain mechanisms using our prop...

Broiler breeder hens are typically provided a restricted amount of feed once a day. This feed is rapidly consumed; therefore, the hens fast for an extended period of time before their next feeding. In the current research, the effects on reproductive performance of implementing a twice-a-day vs. a once-a-day feeding program after photostimulation were investigated. Pullets and cockerels were re...

in this study, the effect of green tea extract was studied on quality of surimi produced from fish silver carp during refrigerated storage. surimi was prepared and immersed with various concentrations of tea extracts (0, 2 and 4%). samples were refrigerated for 15 days and were performed chemical tests include ph, total volatile bases nitrogen (tvb-n), thiobarbitoric acid (tba) test and total b...
