This study aimed to evaluate the effects of in utero administration bisphenol A (BPA) on semen parameters vesper mice. Sixty female Calomys laucha were divided into six groups and received by gavage during gestation following substances: Water (negative control), Olive Oil (vehicle Diethylstilbestrol (DES – positive control 6.5 μg kg−1 bw) BPA (40, 80 200 bw). Male offspring euthanised at 70 days age, sperm analysed. reduced normal morphology (water = 96.1 ± 0.65; BPA200 96.8 2.3%), membrane...
(1) Background: Essential oils have long been used as therapeutic agents. Lavender (Lavandula angustifolia) oil (LO) is an antispasmodic, anticonvulsant, relaxant, painkilling, and antimicrobial essential investigated a natural substance for biomedical therapies. Nanoparticles shown significant promise in improving drug delivery efficacy. Considering these benefits, the aim of this study was to evaluate toxicity LO lavender niosomes (LONs) stem cells myofibroblast models cultured vitro. (2)...
Ovarian tissue cryopreservation is a promising technique for fertility maintenance. The aim of this study was to compare the morphology domestic cat ovarian follicles after with ethylene glycol (EG) and dimethyl sulfoxide (Me2SO). Ovaries from healthy adult cats undergoing elective ovariohysterectomy were used. Eight fragments obtained each pair ovaries: two used as fresh controls; three submitted perfusion toxicity test perfused M199, 10% fetal calf serum 0.4% sucrose containing Me2SO 1.5...
The aim of this study was to assess a slow-freezing protocol cat ovarian tissue cryopreservation using autotransplantation. Four adult queens were ovariohysterectomized and the ovaries fragmented cryopreserved. After one week, grafts thawed autografted subcutaneous dorsal neck each queen, then randomly removed after 7, 14, 28, 49, 63 days transplantation. Percentages morphologically normal primordial growing follicles (MNFs) 88% 97%, respectively, in fresh samples (fresh controls), 74% 100%,...
Ovarian tissue transplantation could be a valuable technique for the preservation of endangered animals. The domestic cat affords an adequate experimental model studies aimed at wild felids due to its phylogenetic similarity. Thus, this pilot study evaluated efficacy ovarian autotransplantation peripheral site. Three adult queens were submitted ovariohysterectomy. ovaries fragmented into eight pieces; two fixed as control and six transplanted subcutaneous dorsal neck. Grafts monitored weekly...
The aim of this study was to evaluate the influence oils on male reproductive parameters in Calomys laucha. Twenty-four animals were distributed into four groups and given following substances by gavage: water, mineral oil, olive oil sunflower oil. After 10 days gavage, euthanised semen collected from them for assessing acrosome integrity carrying out vitro penetration (IVP) test. Acrosome significantly reduced (P < 0.05) vehicles relation control. In all control, but only had statistically...
Stereotyped behaviors in captive primates are often caused by unsuitable conditions. Environmental enrichment has been used to reduce these behaviors, and also increase the frequency of appropriate species. In this pilot study we evaluated whether behavioral influences food intake black tufted-ear marmoset, Callithrix penicillata (É. Geoffroy Saint-Hilaire, 1812), calculating energy maintenance requirements. We 16 individually housed, healthy adult marmosets, randomly divided into two...
BACKGROUND: Examining semen cryopreservation in Calomys laucha offers valuable insights for reproductive research and species conservation. OBJECTIVE: To determine the most effective sugar of C . semen. MATERIALS AND METHODS: Using 36 epididymides from , samples were diluted a 3% skimmed milk medium supplemented with one four sugars (glucose, fructose, lactose, or sucrose) at concentration 0.3 M. These mixtures underwent conditioning phase 37°C 10 min, cooled to −80°C another subsequently...
