Co-receptorA co-receptor is a cell surface receptor that binds a signalling molecule in addition to a primary receptor in order to facilitate ligand recognition and initiate biological processes, such as entry of a pathogen into a host cell. The term co-receptor is prominent in literature regarding signal transduction, the process by which external stimuli regulate internal cellular functioning. The key to optimal cellular functioning is maintained by possessing specific machinery that can carry out tasks efficiently and effectively.
ChlorineChlorine is a chemical element with the symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chlorine is a yellow-green gas at room temperature. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity on the revised Pauling scale, behind only oxygen and fluorine.
Clostridioides difficileClostridioides difficile (syn. Clostridium difficile) is a bacterium that is well known for causing serious diarrheal infections, and may also cause colon cancer. It is known also as C. difficile, or C. diff (siː_dɪf), and is a Gram-positive species of spore-forming bacteria. Clostridioides spp. are anaerobic, motile bacteria, ubiquitous in nature and especially prevalent in soil. Its vegetative cells are rod-shaped, pleomorphic, and occur in pairs or short chains.
Endothelial cell tropismEndothelial cell tropism or endotheliotropism is a type of tissue tropism or host tropism that characterizes an pathogen's ability to recognize and infect an endothelial cell. Pathogens, such as viruses, can target a specific tissue type or multiple tissue types. Like other cells, the endothelial cell possesses several features that supports a productive viral infection a cell including, cell surface receptors, immune responses, and other virulence factors.
Fitness cultureFitness culture is a sociocultural phenomenon surrounding exercise and physical fitness. It is usually associated with gym culture, as doing physical exercises in locations such as gyms, wellness centres and health clubs is a popular activity. An international survey found that more than 27% of world total adult population attends fitness centres, and that 61% of regular exercisers are currently doing "gym-type" activities. Getting and maintaining physical fitness has been shown to benefit individuals' inner and outer health.
Jewish views on evolutionJewish views on evolution includes a continuum of views about the theory of evolution, experimental evolution, the origin of life, age of the universe, evolutionary creationism, and theistic evolution. Today, many Jewish people accept the theory of evolution and do not see it as incompatible with traditional Judaism, reflecting the emphasis of prominent rabbis such as the Vilna Gaon and Maimonides on the ethical rather than factual significance of scripture. Biblical chronology indicates that God completed the creation of the world close to 6,000 years ago.
NorovirusNorovirus, sometimes referred to as the winter vomiting disease, is the most common cause of gastroenteritis. Infection is characterized by non-bloody diarrhea, vomiting, and stomach pain. Fever or headaches may also occur. Symptoms usually develop 12 to 48 hours after being exposed, and recovery typically occurs within one to three days. Complications are uncommon, but may include dehydration, especially in the young, the old, and those with other health problems. The virus is usually spread by the fecal–oral route.
Professional fitness coachA professional fitness coach is a professional in the field of fitness and exercise, most often instruction (fitness instructor), including professional sports club's fitness trainers and aerobics and yoga instructors and authors of fitness instruction books or manuals. Fitness topics may also include nutrition, weight-loss, and self-help. Fitness careers are distinguished from exercise science careers such as athletic training, however the various types of fitness certifications have more and more in common: the, "distinctions.
DichloromethaneDichloromethane (DCM or methylene chloride, methylene bichloride) is an organochlorine compound with the formula . This colorless, volatile liquid with a chloroform-like, sweet odour is widely used as a solvent. Although it is not miscible with water, it is slightly polar, and miscible with many organic solvents. Natural sources of dichloromethane include oceanic sources, macroalgae, wetlands, and volcanoes. However, the majority of dichloromethane in the environment is the result of industrial emissions.
