Aneurysm of the pulmonary artery is a rare condition in animals, and to our knowledge it has never been reported association with neoplasia. This report describes case an adult female sheep “Churra Galega Bragançana” breed aneurysm associated lung cancer (ovine adenocarcinoma).

background: aging contains morphological and functional deterioration in biological systems. d-galactose (d-gal) generates free radicals and accelerates aging. portulaca oleracea (purslane) may have protective effect against oxidative stress. objective: purslane ethanolic extract effects were evaluated on antioxidant indices and sex hormone in d-gal aging female mice. materials and methods: 48 ...

Males of many animals perform 'copulatory courtship' during copulation, but the possible reproductive significance of this behaviour has seldom been investigated. In some animals, including the spider Physocyclus globosus (Pholcidae), the female discards sperm during or immediately following some copulations. In this study, we determined which of several variables associated with copulation cor...

Ticks are ectoparasites (Hematophagous) of wild and domestic animals. These hazardous especially livestock industry all around the world, most ticks species have been caused huge economic losses to animals as well industry. The current study was conducted check prevalence taxonomic identification tick in Tehsil Sinjawi. In 2020 2021 such Rhipicephalus Hyalomma belonging two genera were collecte...

Previous studies showed that Danggui-Shaoyao-San (DSS), a traditional Chinese medicinal prescription, could alleviate cognitive dysfunction of Alzheimer's disease (AD) patients. However, the mechanisms remain unclear; we have now examined the effect of DSS on SAMP8 and elucidated the possible mechanism. Animals were treated with DSS for 2 months, and step-down test and Morris water maze (MWM) t...

Increased levels of androgens in postmenopausal women are considered to be a risk factor for breast cancer. Testosterone, alone or in combination with estrogen, induces epithelial dysplasia and mammary tumors in Noble rats. Since this model of hormone-induced neoplasia has not been reported in other rat strains, we studied the effect of testosterone on the mammary gland morphology of female Wis...

BACKGROUND AND PURPOSE A number of studies indicate that the female gonadal hormone, estrogen, confers protection against cerebrovascular disorders such as stroke. One postulated mechanism for these effects of estrogen is an action on the enzyme endothelial nitric oxide synthase (eNOS), which produces the vasodilatory molecule NO. We have investigated the hypothesis that estrogen increases expr...

The medial preoptic area (MPOA) is an important integrative site for male sexual behavior. We have reported an increase in dopamine (DA) release in the MPOA of male rats shortly before and during copulation. Postcastration loss of copulatory ability mirrored the loss of the precopulatory DA response to an estrous female. The present study investigated the time courses of restoration, rather tha...

Long-acting GSK1265744 (GSK744 LA) is a strand transfer inhibitor of the HIV/SIV (simian immunodeficiency virus) integrase and was shown to be an effective preexposure prophylaxis (PrEP) agent in a low-dose intrarectal SHIV (simian-human immunodeficiency virus) rhesus macaque challenge model. We examined the pharmacokinetics and efficacy of GSK744 LA as PrEP against repeat high-dose intravagina...
