1. A New Electrochemical Platform Based on a Polyurethane Composite Electrode Modified with Magnetic Nanoparticles Coated with Molecularly Imprinted Polymer for the Determination of Estradiol Valerate in Different Matrices
A polyurethane composite electrode modified with magnetic nanoparticles (mag; Fe3O4) coated with molecularly imprinted polymers (MIPs) was developed for the electrochemical determination of estradiol valerate. Chemical and morphological analyses of the mag-MIP were performed using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (E

2. Effect of bee venom on IL-6, COX-2 and VEGF levels in polycystic ovarian syndrome induced in Wistar rats by estradiol valerate
Background : Polycystic ovarian syndrome (PCOS) is a low-grade inflammatory disease characterized by hyperandrogenemia, hirsutism, chronic anovulation and vascular disorder. Interleukin-6 (IL-6), cyclooxygenase-2 (COX-2) and vascular endothelial growth factor (VEGF) are triggered by inflammatory stimuli and lead to angiogenesis and pathogenesis of the ovary

3. Effects of acupuncture and electroacupuncture on estradiol-induced inflammation and oxidative stress in health rodents
PURPOSE:To investigate the effects of classical acupuncture (Ac) and electroacupuncture (EAc) on estradiol-induced inflammation and oxidative stress in health rodents. METHODS: Twenty-four eight-week old female rats were treated with estradiol valerate (EV) 4.0 mg i.m. single dose and randomly assigned to four groups (n=6): G1(control), G2 (Ac), G3 (EAc 2 Hz

4. Caracterização dos fármacos Mebendazol e Estradiol 17β Valerato no estado sólido / Characterization of the drug Mebendazole and 17β Valerate in solid state
Os Insumos farmacêuticos ativos (IFA) são em sua maioria produzidos e comercializados na forma de formulações sólidas. A eficácia terapêutica de cada IFA, no entanto, está diretamente relacionada com suas características no estado sólido. Desta forma, o controle e o entendimento da química das características físico-químicas de estado sólido d

5. Efeitos da Acupuntura, Eletroacupuntura e Metformina Sobre o Estresse Oxidativo, InflamaÃÃo e Glicemia em Ratas Sadias Submetidas a EstÃmulo EstrogÃnico / EFFECTS OF ACUPUNCTURE, ELETROACUPUNCTURE AND METFORMIN ON OXIDATIVE STRESS, INFLAMMATION AND BLOOD GLUCOSE IN HEALTHY RATS SUBMITTED TO ESTROGENIC STIMULATION
The physiological performance of cellular activity requires a balance between the production of free radicals and their deactivation by regulators and surge protectors. When this balance is broken, the oxidative stress takes place. Several experimental studies using estrogens to induction of ovarian and metabolic disorders, with emphasis on the polycystic ov

6. Effectiveness of estradiol valerate on sex reversion in Astyanax altiparanae (Characiformes, Characidae)
The objective of this study was to evaluate the effectiveness of estradiol valerate in an attempt to feminize the male Astyanax altiparanae. One thousand newly-hatched larvae were randomly distributed in four incubators. During a period of 30 days, estradiol valerate was administered in different dosages (20, 40, and 80 mg/kg of diet); the control group did

7. Bee venom treatment reduced C-reactive protein and improved follicle quality in a rat model of estradiol valerate-induced polycystic ovarian syndrome
Polycystic ovarian syndrome (PCOS) is a low grade inflammatory disease characterized by hyperandrogenemia and chronic anovulation. C-reactive protein (CRP), released by adipocytes, plays a key role in PCOS. Apis mellifera honeybee venom (HBV) contains a variety of biologically active components with various pharmaceutical properties. This study was designed

9. Chronic treatment with the nitric oxide synthase inhibitor, L-NAME, attenuates estradiol-mediated improvement of learning and memory in ovariectomized rats
INTRODUCTION: The role of ovarian hormones and nitric oxide in learning and memory has been widely investigated. OBJECTIVE: The present study was carried out to evaluate the effect of the nitric oxide synthase (NOS) inhibitor, N (G)-nitro-L-arginine methyl ester (L-NAME), on the ability of estradiol to improve learning in OVX rats using the Morris water maze

10. Dinâmica folicular de vacas de corte tratadas com três protocolos de sincronização da ovulação =Ovarian follicular dynamics in beef cows treated with three protocols of synchronization of ovulation / Ovarian follicular dynamics in beef cows treated with three protocols of synchronization of ovulation
Background: Artificial insemination is an established and viable technique to accelerate the genetic advancement and economic return of the cattle. However, compromises the efficiency of detection of estrus results in low insemination rates. To avoid these problems in beef herd, synchronization protocols have been developed that allow inseminate large number

11. The effect of chronic administration of L-arginine on the learning and memory of estradiol-treated ovariectomized rats tested in the morris water maze
OBJECTIVE: The present study was carried out to evaluate the effect of L-arginine on the learning and memory of estradiol-treated ovariectomized (OVX) rats. METHODS: Forty-eight rats were divided into six groups: (1) sham, (2) OVX, (3) sham-Est, (4) OVX-Est, (5) sham-Est-LA, and (6) OVX-Est-LA. The animals of the sham-Est and OVX-Est groups were treated by w

12. UV derivative spectrophotometric method for determination of estradiol valerate in tablets
A derivative UV spectrophotometric method for determination of estradiol valerate in tablets was validated. The parameters specificity, linearity, precision, accuracy, limit of detection and limit of quantitation were studied according to validation guidelines. The first-order derivative spectra were obtained at N = 5, Δλ = 4.0 nm, and determinations were
