Testosterone (medication)
Testosterone is a medication and naturally occurring steroid hormone. It is used to treat male hypogonadism, gender dysphoria, and certain types of breast cancer. It may also be used to increase athletic ability in the form of doping. It is unclear if the use of testosterone for low levels due to aging is beneficial or harmful. Testosterone can be administered through several different routes, including topical gels or patches, nasal sprays, subdermal implants, or tablets dissolved inside the mouth. Testosterone therapy has been associated with improvements in depressive symptoms (especially in hypogonadal men), increased exercise capacity and muscle strength in men with chronic heart failure, and male contraception effectiveness. Common side effects of testosterone include acne, swelling, and breast enlargement in men. Serious side effects may include liver toxicity, heart disease, and behavioral changes. Women and children who are exposed may develop masculinizatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxford Dictionaries (website)
''Lexico'' was a dictionary website that provided a collection of English and Spanish dictionaries produced by Oxford University Press (OUP), the publishing house of the University of Oxford. While the dictionary content on ''Lexico'' came from OUP, this website was operated by Dictionary.com, whose eponymous website hosts dictionaries by other publishers such as Random House. The website was closed and redirected to Dictionary.com on 26 August 2022. Before the Lexico site was launched, the '' Oxford Dictionary of English'' and '' New Oxford American Dictionary'' were hosted by OUP's own website ''Oxford Dictionaries Online'' (''ODO''), later known as ''Oxford Living Dictionaries''. The dictionaries' definitions have also appeared in Google definition search and the Dictionary application on macOS, among others, licensed through the Oxford Dictionaries API. History In the 2000s, OUP allowed access to content of the '' Compact Oxford English Dictionary of Current English'' on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conjugation (biochemistry)
Bioconjugation is a chemical strategy to form a stable Covalent bond, covalent link between two molecules, at least one of which is a biomolecule. Methods to conjugate biomolecules are applied in various field, including medicine, diagnostics, biocatalysis and materials. Synthetically modified biomolecules can have diverse functionalities, such as tracking cellular events, revealing enzyme function, determining protein biodistribution, Imaging science, imaging specific biomarkers, and delivering Pharmaceutical drug, drugs to targeted cells. Bioconjugation is a crucial strategy that links these modified biomolecules with different Substrate (biochemistry), substrates. Besides applications in biomedical research, bioconjugation has recently also gained importance in nanotechnology such as bioconjugated quantum dots. The most common types of bioconjugation include coupling of a small molecule (such as biotin or a fluorescent dye) to a protein. Antibody-drug conjugates such as Br ...

Doping In Sport
In competitive sports, doping is the use of banned athletic performance-enhancing drugs (PEDs) by athletes, as a way of cheating. As stated in the World Anti-Doping Code by WADA, doping is defined as the occurrence of one or more of the anti-doping rule violations outlined in Article 2.1 through Article 2.11 of the Code. The term ''doping'' is widely used by organizations that regulate sporting competitions. The use of drugs to enhance performance is considered unethical and is prohibited by most international sports organizations, including the International Olympic Committee. Furthermore, athletes (or athletic programs) taking explicit measures to evade detection exacerbate the ethical violation with overt deception and cheating. The origins of doping in sports go back to the creation of the sport itself. From ancient usage of substances in chariot racing to more recent controversies in doping in baseball, doping in tennis, doping at the Olympic Games, and doping at the T ...

Athletic Ability
Athletics is a term encompassing the human competitive sports and games requiring physical skill, and the systems of training that prepare athletes for competitive performance. Athletic sports or contests are competitions which are primarily based on human physical competition, demanding the qualities of stamina, fitness, and skill. Athletic sports form the bulk of popular sporting activities, with other major forms including motorsports, precision sports, extreme sports and animal sports. Athletic contests, as one of the earliest types of sport, are prehistoric and comprised a significant part of the Ancient Olympic Games, along with equestrian events. The word "athletic" is derived from the (athlos) meaning "contest." Athletic sports became organized in the late 19th century with the formation of organizations such as the Amateur Athletic Union in the United States and the Union des Sociétés Françaises de Sports Athlétiques in France. The Intercollegiate Athletic Associa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
