BACKGROUND: Injury rates among professional baseball players may reach as high as 5.8 per 1000 encounters, with pitchers being most vulnerable on account of the excessive biomechanical load on the upper extremity during the throwing motion. Anatomically, the shoulder is the most common site of pitching-related injury, accounting for 30.7% of injuries, closely followed by the elbow at 26.3%. Characteristic valgus loading imparts a predictable constellation of stresses on the joint, including medial tension, lateral compression, and posterior medial shearing...

This study reports a comprehensive description of penaeid spermatogenesis (Penaeus monodon) by light and transmission electron microscopy. A conspicuous characteristic of spermatocytogenesis was a ring-like structure with high electron-density adjacent to the nucleus of a primary spermatocyte. During the spermiogenesis from stage I (StI) to stage VI spermatid (StVI), the formation of the acrosome and decondensation of the nucleus were the most notable morphological transformations. StIs were small and compact and they were contained in the syncytia...
