Background: Contraceptive vaccines (CVs) can be used as a valuable and alternative method for the prevention of gestation in humans and animals. These vaccines can have several targets, such as superficial sperm proteins. Vaccines based on sperm antigens are quite efficacious to create a contraceptive effect. However, multi-epitope vaccines are more effective in stimulating the immune system an...

BACKGROUND AND PURPOSE To analyze the effects of substrain and gender differences in spontaneously hypertensive rats (SHR) and distal middle cerebral artery (MCA) branching patterns on infarct size, we compared infarct volumes produced by photothrombotic distal MCA occlusion using SHR/Kyushu and SHR/Izumo (Izm). METHODS Twenty-four male and 8 female SHR/Kyushu, 15 male and 5 female SHR/Izm, a...

Progeny (n = 589) of randomly mated Duroc pigs were used to determine the genetic and phenotypic relationships between individual s.c. backfat layers and i.m. fat percent (IMF) of the longissimus. Five days before slaughter, cross-sectional ultrasound images were collected at the 10th rib by a National Swine Improvement Federation-certified ultrasound technician using an ultrasound machine (Alo...

A Room Impulse Response (RIR) shows a complex time-frequency structure, due to the presence of sound re ections and room resonances at low frequencies. Many acoustic signal enhancement applications, such as acoustic feedback cancellation, dereverberation and room equalization, require simple yet accurate models to represent a RIR. Parametric modeling of room acoustics attempts at approximating ...

PURPOSE Glaucomatous neuropathy can be a consequence of insufficient blood supply, increase in intraocular pressure (IOP), or other risk factors that diminish the ocular blood flow. To determine the ocular perfusion pressure (OPP) in normal and systemic hypertensive patients. MATERIALS AND METHODS One hundred and twenty-one patients were enrolled in this prospective and comparative study and ...

This manuscript reviews sperm morphology and its disorders in the context of infertility. A new look into an old challenge is delivered, based on contemporary scientific clinical evidence. We highlight functional repercussions aberrations dissect cause effect a variety insults pathogenic mechanisms focusing relationships among shape, function, compartmental analysis cellular subcellular structu...
