The contribution of different sperm parameters to better explain ram semen cryoresistance.

In order to determine an effective procedure for explaining ram sperm cryoresistance and develop a new model for breeders classification, a retrospective study was conducted using sperm analysis data obtained over two consecutive years from a total of 82 sessions of ram semen cryopreservation. In each session, fresh ejaculates from eight males were collected via artificial vagina, pooled and frozen in liquid nitrogen vapors. After thawing, a total of 19,084 sperm tracks and 11,319 morphometric measurements were analysed.

Indicators of immunosuppression peripartum in dual purpose cows in the tropics affected health, productive and reproductive parameters.

The objective of the study was to identify immunosuppression peripartum indicators in dual purpose cows in the tropics and determine their effects on productive and reproductive parameters. The indicators used were: changes in leukocyte and neutrophils population, concentrations of energy metabolites (β-hydroxybutyrate and glucose) and body condition scores (BCS). Blood sampling and BCS (scale 1 - 5) were taken weekly during the peripartum.

The Re-Addition of Seminal Plasma after Thawing Does Not Improve Buck Sperm Quality Parameters.

In order to achieve a higher post-thaw buck sperm quality, an approach in the thawing protocol of cryopreserved sperm doses under in vitro capacitation conditions mimicking the in vivo female environment was studied. Therefore, functional and kinetic characteristics of buck thawed sperm from males of different ages, the season of collection, and melatonin implanted males in the non-breeding season were assessed after 3 h of incubation in an in vitro fertilization (IVF) media with 20% of buck seminal plasma (SP). Previously, fresh ejaculates were collected via artificial vagina from eight males of the breed during two consecutive years in breeding and non-breeding periods.

Soy lecithin as a potential alternative to powdered egg yolk for buck sperm cryopreservation does not protect them from mitochondrial damage.

The aim of this study was to address whether soy lecithin (SL) was an effective non-penetrating cryoprotectant for buck sperm cryopreservation in the presence of seminal plasma. There was also an attempt to determine the optimal concentration of BHT as an antioxidant in powdered egg yolk (PEY) or in SL based media. Two ejaculates were collected from six bucks and mixed ejaculates were aliquoted into washed, using centrifugation procedures, and unwashed samples.

Serous adenocarcinoma of the fallopian tube, associated with verrucous carcinoma of the uterine cervix: a case report of synchronic rare gynecological tumors.

Background: Synchronous gynecological tumors are rare; it is even rarer to find the rarest of gynecological tumors that of the fallopian tube, together with a histological sub-type as rare as verrucous cervix.

Case Presentation: We report a synchronic fallopian tube adenocarcinoma and a verrucous cervical cancer. A 85-year-old woman with postmenopausal genital hemorrhage, endometrial biopsy was reported as squamous metaplasia, an exploratory laparotomy was performed finding a tubal tumor diagnosed as adenocarcinoma, a staging procedure was performed.
