(physical chemistry) a fourth state of matter distinct from solid or liquid or gas and present in stars and fusion reactors; a gas becomes a plasma when it is heated until the atoms lose all their electrons, leaving a highly electrified collection of nuclei and free electrons; "particles in space exist in the form of a plasma"
a green slightly translucent variety of chalcedony used as a gemstone
the colorless watery fluid of the blood and lymph that contains no cells, but in which the blood cells (erythrocytes, leukocytes, and thrombocytes) are suspended (同)plasm, blood_plasma
any of a large group of nitrogenous organic compounds that are essential constituents of living cells; consist of polymers of amino acids; essential in the diet of animals for growth and for repair of tissues; can be obtained from meat and eggs and milk and legumes; "a diet high in protein"

It is known that estrogens act on the male reproductive tract by binding to estrogen receptors (ER) α and β. However, studies on ER localization in the human testis are discordant. The aim of this study was to investigate the localization of ERα in the testes of adult men with normal spermatogene

Cryopreservation is widely used to preserve the quality of bull spermatozoa over time. Sequestration of seminal plasma proteins by low density lipoproteins and formation of a protective film around the spermatozoa membrane by low density lipoproteins were the main mechanisms proposed. However, the o

Ubiquitin is an 8.5-kDa protein that tags outlived proteins for degradation by the proteasome. It also marks defective spermatozoa during epididymal passage and has been proposed as a biomarker of sperm quality. This study evaluates the relationship between sperm ubiquitination, protamine deficiency

… It has been reported that the total protein of DJ-1 was decreased in a proteomic analysis of seminal plasma from asthenozoospermia patients and a DJ-1 protein acts as a sensor of cellular redox homeostasis. … Therefore, we evaluated the age-related changes in the ratio of the oxidized/reduced forms of the DJ-1 protein in the epididymis. …
