Beta Sitosterol is a plant sterol that lowers cholesterol levels by inhibiting its absorption in the intestine and reducing oxidation capacity. It has antioxidant qualities, may prevent cancer, reduce prostate enlargement, improve urine flow, and support the immune system. It is found in various natural sources and fortified dietary sources. Beta Sitosterol is a type […]
The beta hCG test is a blood test that accurately detects pregnancy in its early stages by measuring hCG levels. It can also be used to monitor the health of a known pregnancy. However, hCG levels should not be used to determine gestational age or viability unless compared to previous results. Doctors may perform the […]
Beta glucans are natural sugars found in algae, bacteria, lichens, yeasts, and plants like barley and oats. They are used in food additives and medicines to reduce cholesterol levels and strengthen the immune system. Beta glucans can also help control blood sugar and have been shown to increase the survival rate in some cancer patients. […]
Creatine and beta alanine are supplements used by athletes to increase athletic performance and protect muscles from damage. When combined, they can reportedly enable power increases of up to 35-40%. Beta alanine is taken daily for 4-5 weeks, followed by creatine for one week. Alternatively, both supplements can be taken every day. Creatine enhances aerobic […]
Beta-carotene is a nutrient found in fruits and vegetables, particularly carrots, and is important for vitamin A deficiency. It has antioxidant properties and may have anti-cancer effects. It is best consumed in its natural state and supplements may be harmful for some people, particularly smokers. A healthy diet is the best way to obtain beta-carotene, […]
Beta Alanine is an amino acid that aids muscle building and repair. It can be found in protein-rich foods or taken as a supplement. It has immediate effects such as vasodilation and paresthesia, and long-term effects such as increased muscle strength and endurance. Its main component, carosine, helps decrease muscle fatigue. It is a popular […]
Beta-blockers are drugs that block or nullify the function of adrenaline, reducing heart rate and blood pressure. They are used to treat congestive heart failure, abnormal heart rhythms, angina, migraines, hyperthyroidism, and glaucoma. Beta-blockers can also help with anxiety-producing situations, but may cause side effects such as dizziness, insomnia, and weight gain. They are not […]
Beta-carotene is a plant-based molecule that can be converted into vitamin A by the body. Other carotenoids can also be converted into vitamin A. Vitamin A is stored in the liver and too much preformed vitamin A can cause disease, while too much beta-carotene is usually harmless. Too little vitamin A can cause developmental problems, […]
Beta particles are high-speed electrons or positrons released from radioactive nuclei. They are one of the least harmful forms of radiation but still pose a significant health problem. Beta emitters include strontium-90, potassium-40, technetium-99, tritium, and carbon-14. Beta particles cause ballistic damage and break chemical bonds, creating tissue-damaging ions. They are used in radioisotope thermoelectric […]
Beta decay is a type of radioactive decay where the nucleus emits a beta particle, used in medical applications. It occurs when an atom is unstable due to excess neutrons or protons, converting them to stabilize the nucleus and transforming the atom into another element. Beta particles can be electrons or positrons, and have a […]
Beta-carotene is a fat-soluble pigment found in orange and yellow fruits and vegetables that can be converted into vitamin A. It is an antioxidant that may protect against chronic diseases, but there is no recommended daily intake. Beta-carotene deficiency may be common in those with low fruit and vegetable intake, and supplements should be used […]
Amyloid beta peptide plays a role in Alzheimer’s and other neurological diseases. Beta-amyloid plaques form from a 42-amino acid long peptide, inhibiting brain function. Genetic inheritance of the 42AA peptide increases the risk of Alzheimer’s. Potential therapies include beta-secretase and gamma-secretase inhibitors, as well as amyloid beta antibodies. Amyloid beta protein is a large peptide […]
Beta receptors are part of the sympathetic nervous system and respond to adrenaline and norepinephrine. There are three types of beta receptors, found in the heart, blood vessels, airways, uterus, and fatty tissue. Drugs that stimulate or block beta receptors are used to treat conditions like asthma and high blood pressure. Beta receptors, or beta […]
A beta release is a new version of software that hasn’t been fully tested for bugs yet. It can be open or closed, and testers sign up for beta mailing lists. Beta testing reveals conflicts with other programs or hardware. Users should back up important files before downloading a beta version. The beta release is […]
A new product goes through alpha and beta stages of development before commercial release. Beta versions are previews for testing and feedback, with limited technical support. Websites also use beta versions for compatibility testing. The term “beta” originated from early IBM hardware testing and is now commonly used. When a new product, such as a […]
Stock beta is a measure of a stock’s volatility and potential earnings compared to the broader market, expressed as a ratio. A score above or below one indicates higher or lower returns than the market. High beta stocks are riskier but can earn higher returns, while low beta stocks are more stable but offer limited […]
Beta peptides are macromolecules made up of beta amino acids that mimic or enhance the effects of alpha peptide drugs. Unlike alpha peptides, beta peptides are not commonly found in nature. Beta peptides are used in medicine as they resist proteolysis. The Arndt-Eistert reaction is used to synthesize beta peptides. A beta peptide is a […]
Alternate beta is a type of investment strategy that exposes investors to different market risks than traditional beta strategies. It involves choosing different markets to invest in and using different methods than alpha investors. Hedge funds often claim to use alpha strategies, but some analysts believe that this is actually a type of beta. Investors […]
Beta carotene overdose can cause orange or yellow skin discoloration, diarrhea, bruising, and dizziness. It can be easily treated by discontinuing use or reducing dosage. Long-term use and smoking can increase the risk of side effects. Whole foods are recommended as a safer source of beta carotene. Alcohol and fat replacement products can hinder its […]
Beta strep is a bacteria that can affect pregnant women and cause serious health risks to the unborn child if left untreated. It can be found in the rectum, bladder, vagina, and mouth and can lead to infections of the bladder, kidneys or uterus. Pregnant women are tested for it and treated with antibiotics to […]
