The conversion of dehydroepiandrosterone into androst-5-ene-3 beta,17 beta-diol (androstenediol) is increased in endometria from untreated women with polycystic ovarian syndrome
(ELSEVIER, 2010-12)
The changes in endometrial homeostasis found in women with polycystic ovarian syndrome (PCOS)
could be associated with alterations in the intracrine metabolism of steroid hormones. The uptake
of dehydroepiandrosterone-sulphate ...
Inhibition of cytochrome P450 activity enhances the systemic availability of triclabendazole metabolites in sheep
(Wiley Blackwell Publishing, Inc, 2009-08)
Understanding the disposition kinetics and the pattern of metabolism is critical to optimise the flukicidal activity of triclabendazole (TCBZ) in ruminants. TCBZ is metabolised by both flavin-monooxygenase (FMO) and ...
Unravelling ties in the nitrogen network: Polyamines and nitric oxide emerging as essential players in signalling roadway
(Wiley Blackwell Publishing, Inc, 2020-09)
Nitrogen (N) is a central mineral nutrient essential for plant development and growth. It is usually scarcely found in soils, so the knowledge of the overall plant N metabolism deserves substantial attention. Polyamines ...
Metabolic stability of glifosate in ruminal content from cattle: partition between particulate and fluid digestive material
(Fundación Revista Medicina, 2019)
Glyphosate (GLP) is one of the most commonly pesticides delivered to the environment. Farm animals could be exposed to both GLP and aminomethylphosphonic acid (AMPA, the major GLP metabolite) present in surface and ...
Effects of food processing and fibre content on the digestibility, energy intake and biochemical parameters of Blue-and-gold macaws (Ara ararauna L. - Aves, Psittacidae)
(Wiley-Blackwell, 2014-04-01)
Considering the increased incidence of obesity and metabolic diseases in caged psittacines, the effect of fibre and food processing was evaluated in the Blue-and-gold macaw. Four food formulations (0%, 7%, 14% and 21% of ...
Rice co-products in pig feed during the starter phase (15 to 30 kg)
(2018-07-01)
This study was carried out to evaluate the inclusion of two rice co-products in pig feed during the starter phase in terms of the nutritional value and digestibility of the co-products, and the effect on plasma parameters, ...
Gender-specific impairment of in vitro sinoatrial node chronotropic responses and of myocardial ischemia tolerance in rats exposed prenatally to betamethasone
(2017-11-01)
Excessive fetal glucocorticoid exposure has been linked to increased susceptibility to hypertension and cardiac diseases in the adult life, a process called fetal programming. The cardiac contribution to the hypertensive ...
Lipid microspheres containing urea for slow release of non-protein N in ruminant diets
(2022-01-01)
Context: Urea is widely used in ruminant diets as a source of non-protein nitrogen (NPN), partially substituting for true protein in feed, but high levels of urea in the diet may cause toxicity. Aims: This study investigated ...
Dietary nitrate and presence of protozoa increase nitrate and nitrite reduction in the rumen of sheep
(Wiley, 2020-04)
Nitrate (NO−3) supplementation is an effective methane (CH4) mitigation strategy for ruminants but may produce nitrite (NO−2) toxicity. It has been reported that rumen protozoa have greater ability for NO−3 and NO−2 reduction ...
Influence of CYP3A4/5 Polymorphisms in the pharmaconetics of levonorgestrel: a pilot study
(2012)
Introduction.
Levonorgestrel a synthetic progestagen used for
endometriosis, dysmenorrhea and
emergency contraception, is quickly and completely absorbed in the digestive tract. levonorgestrel
is predominantly metabolised ...
