Period of Boar Ejaculate Collection Contributes to the Yearly Intra-Male Variability of Seminal Plasma Cytokines

The Seminal Plasma of the Boar is Rich in Cytokines, with Significant Individual and Intra-Ejaculate Variation.

PROBLEM The boar, as human, sequentially ejaculates sperm-rich and sperm-poor fractions. Seminal plasma (SP) spermadhesins (PSP-I/PSP-II) induce a primary endometrial inflammatory response in female sows, similar to that elicited by semen deposition in other species, including human. However, the SP is also known to mitigate such response, making it transient to allow for embryo entry to a clea...

نقد و بررسی کتاب the collection of the quran

جان برتن استاد بازنشسته دانشگاه سنت‏اندروز، مولف کتاب جمع‏آوری قرآن است. این اثر در سال 1977 توسط انتشارات دانشگاه کمبریج به چاپ رسید. در نگاه اول، اثر مذکور مشتمل بر دو بخش و هر بخش دارای پنج فصل است. مولف در بخش اول به مسأله نسخ می‏پردازد و در مورد این که آیا قرآن سنت را نسخ کرده و یا بالعکس، به تفصیل سخن می‏گوید. نظرات شافعی و مخالفانش را در این‏باره به طور مشروح بیان می‏کند. وی سه شکل ن...

Boar sperm cryosurvival is better after exposure to seminal plasma from selected fractions than to those from entire ejaculate.

Boar bulk ejaculates are now being collected instead of usual sperm-rich fractions (SRF) for artificial insemination purpose. The present study evaluated the influence of holding boar sperm samples before freezing surrounded in their own seminal plasma (SP), from either fractions/portions or the entire ejaculate, on post-thawing sperm quality and functionality. Ejaculates collected as bulk (BE)...

Characterization of the porcine seminal plasma proteome comparing ejaculate portions.

UNLABELLED Full identification of boar seminal plasma (SP) proteins remains challenging. This study aims to provide an extensive proteomic analysis of boar SP and to generate an accessible database of boar SP-proteome. A SP-pool (33entire ejaculates/11 boars; 3ejaculates/boar) was analyzed to characterize the boar SP-proteome. Twenty ejaculates (5 boars, 4ejaculates/boar) collected in portions ...
