Impact of a Competency Training Course, on the Job Profile of Veterinary Medicine Graduates in Northeastern Brazil.

The present study identified professional training aspects in veterinary medicine at a federal public university in the Northeast of Brazil based on the graduates perception. The outcome of this study is anticipated to facilitate updating of pedagogical project execution of the courses in related areas to improve their curriculum. Hence, the course coordination started monitoring the graduates using an online questionnaire on the course webpage.

Reproductive outcomes of neonatal exposure to betamethasone in male and female rats.

Betamethasone (BM) is the drug of choice for antenatal corticosteroid therapy for women at risk of preterm delivery because it induces fetal lung maturation and enhances survival after birth. However, our group reported evidence of fetal programming and impaired reproductive development and function in rats exposed during the critical window of genital system development. Therefore, we aimed to investigate the effects of BM on the sexual development of rats in the period that corresponds to antenatal corticosteroid therapy in humans.

Rosuvastatin exposure in female Wistar rats alters uterine contractility and do not show evident (anti)estrogenic effects.

Statins are 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase inhibitor drugs that lead to serum-cholesterol-lowering effects. Rosuvastatin, a third-generation statin, has shown better results in reducing cholesterol concentrations when compared to other widely prescribed statins. Recent studies by our group reported that rosuvastatin impairs reproductive function in rats possibly by disrupting the reproductive-endocrine axis.

Effects of isolated or combined exposure to sibutramine and rosuvastatin on reproductive parameters of adult male rats.

Many obese patients are exposed to hypolipidemic and serotonin-norepinephrine reuptake inhibitor (SNRI) drugs. Statins are one of the most marketed drugs in the world to treat dyslipidemia, while sibutramine, a SNRI drug, is prescribed in some countries to treat obesity and is detected as an additive in many adulterated weight loss supplements marketed worldwide. Previous studies reported adverse effects of isolated exposure to these drugs on male rat reproductive parameters.

Impact of intrauterine exposure to betamethasone on the testes and epididymides of prepubertal rats.

Therapy with betamethasone, a synthetic glucocorticoid, is used in cases of preterm birth risk, in order to promote fetal lung maturation, and decrease neonatal mortality and morbidity. However, late reproductive disorders related to the prenatal exposure to this compound have been reported by our Laboratory, in both male and female rats. Thus, the present study aimed to evaluate the impact of betamethasone on postnatal reproductive development, during pre-puberty, of male offspring exposed in utero to this synthetic glucocorticoid.

Ascorbic acid co-administered with rosuvastatin reduces reproductive impairment in the male offspring from male rats exposed to the statin at pre-puberty.

Obesity during childhood and adolescence is closely related to dysfunctions on lipid profile in children. Rosuvastatin is a statin that decreases serum total cholesterol. Ascorbic acid is an important antioxidant compound for male reproduction.

Chrysin Administration Protects against Oxidative Damage in Varicocele-Induced Adult Rats.

Oxidative stress is known as the leading factor responsible for varicocele-related infertility and for that reason, many antioxidant therapies have been proposed. Considering that, we evaluated the reproductive outcomes and fertility of varicocelized rats and the impact of chrysin within these parameters. The animals were allocated into three groups: sham (control), varicocele treated via gavage with 50 mg/kg/day of chrysin (V1), or vehicle (V2) for 56 days.

Arsenic trioxide exposure impairs testicular morphology in adult male mice and consequent fetus viability.

The acute promyelocytic leukemia (APL) is a rare disease, affecting 0.1/100,000 individuals globally. Despite significant advances in APL therapy, some patients still experience relapsed disease.

Betamethasone causes intergenerational reproductive impairment in male rats.

Prenatal betamethasone (BM) exposure in rats negatively impacts sperm quality and male fertility. Studies have shown that BM can cause multi-generational effects on the pituitary-adrenal-axis of rats. The objective of this study was to assess the reproductive development and fertility of male rats (F2) whose fathers (F1) were exposed to BM (0.

Sperm quality and fertility in rats after prenatal exposure to low doses of TCDD: A three-generation study.

Exposure to Tetrachlorodibenzo-p-dioxin (TCDD) in male rats promotes, decreased sperm concentration, alterations in motility and in sperm transit time. We evaluated the effect transgenerational of in utero exposure to low doses TCDD in the sperm quality. Pregnant rats (F0) were exposed to 0.

Long-term effects of in utero and lactational exposure to butyl paraben in female rats.

Parabens are used as preservatives in cosmetic, pharmaceutical, and food industries, and are frequently detected as contaminants in human fluids and tissues. The endocrine disrupting effects of parabens in female rodents include uterotrophic response, steroidogenesis impairment, and ovarian disturbances. The objective of this study was to determine the effects of maternal butyl paraben (BP) exposure on female sexual development.

Sexual differentiation and reproductive development of female rat offspring after paternal exposure to the anti-tumor pharmaceutical cisplatin.

Cisplatin (CP) is used to treat a number of cancers, including testicular cancer. Studies indicate that CP-treatment can impair spermatogenesis in humans and rodents by germ cell DNA binding, through different modes of action. CP-paternal exposure resulted in adverse effects in F1 male offspring.

The Coadministration of N-Acetylcysteine Ameliorates the Effects of Arsenic Trioxide on the Male Mouse Genital System.

Arsenic trioxide (As2O3) has shown effectiveness in treatment of leukemia but is also associated with reproductive toxicity. Since remediation with N-acetylcysteine (NAC) may mitigate the adverse effects caused by exposure, we assessed the effects of As2O3 and its potential reversibility after exposure cessation or coadministration of NAC. Animals received 0.

Lack of Reproductive Toxicity in Adult Male Rats Exposed to Interferon-Alpha.

Interferon-alpha (IFN- α), a type I IFN, is a protein with antiviral, antiproliferative, and immunoregulatory activities, widely used in the treatment of several types of cancers as well as hepatitis B and C. Decrease of libido and erectile dysfunction are commonly reported by male patients during treatment of chronic hepatitis C with IFN- α . However, IFN therapy-associated underlying factors attributed to sexual dysfunction are still not well defined.

Absence of effects on the rat sperm quality after subacute exposure to low doses of fungicide prochloraz.

Prochloraz (PCZ) is a fungicide and androgen-receptor antagonist used worldwide in horticulture and agriculture. Pre- and perinatal exposure to this pesticide during sexual differentiation is deleterious for male offspring. Since data on the effects of PCZ on epididymal functions are scarce, and because sperm maturation occurs in this organ, the present investigation aimed to determine whether low PCZ doses administered to rats during the phase of sperm transit through the epididymis might affect the morphophysiology of this organ and sperm quality.

Phytoremediation potential of Maná-Cubiu (Solanum sessiliflorum Dunal) for the deleterious effects of methylmercury on the reproductive system of rats.

Methylmercury, organic form of mercury, can increase the number of abnormal sperm and decrease sperm concentration and testosterone levels possibly due to the damage caused by reactive species to germ and Leydig cells. Maná-cubiu (Solanum sessiliflorum Dunal) is a native fruit from Amazon rich in iron, zinc, niacin, pectin, and citric acid, used in foods, beverages, and medicinal purposes, since it has been useful for treatment of various diseases caused by oxidative stress or nutritional deficiency. Therefore, this study evaluated the phytoremediation potential of this fruit on damages caused by exposure to MeHg on sperm quantity and quality and the histological aspect of the testis and epididymis.
