"Aminoglycoside" Natural Recordings by Native Speakers
Aminoglycosides are a class of antibiotics that are effective against a wide range of bacteria. They work by interfering with bacterial protein synthesis, ultimately leading to the death of the bacteria. Common examples include gentamicin, streptomycin, and kanamycin. These antibiotics are typically used to treat serious infections, but they can have side effects such as kidney damage, hearing loss, and nerve toxicity.
1. The patient was prescribed an aminoglycoside antibiotic to treat their severe bacterial infection.
2. Aminoglycosides are known for their potent activity against gram-negative bacteria, but they can also cause hearing loss as a side effect.
3. Due to the risk of nephrotoxicity, the dosage of aminoglycosides must be carefully monitored in patients with kidney dysfunction.
4. In the laboratory, scientists are working on developing new aminoglycosides with reduced toxicity and increased resistance to bacterial enzymes.
5. The combination of a beta-lactam antibiotic and an aminoglycoside is often used to enhance the treatment efficacy against multidrug-resistant organisms.
Aminoalkane refers to a compound that is derived from an alkane by replacing one or more hydrogen atoms with amino (-NH2) groups. It is a type of organic compound consisting of a hydrocarbon chain with one or more amino groups attached to it. These compounds can be considered as derivatives of alkanes with amino groups取代了部分或全部的氢原子,在化学中常用于合成各种生物分子和药物。
Aminobenzene is an organic compound consisting of a benzene ring with one amino group (-NH2) attached to it. It is a colorless liquid with a distinct odor and is used primarily as a precursor in the production of dyes, pharmaceuticals, and other chemical compounds. It is also known as aniline and has hazardous properties, being toxic and potentially carcinogenic.
Aminobenzoic acid is a compound consisting of a benzene ring with a carboxylic acid group and an amino group attached to it. It is also known as para-aminobenzoic acid (PABA) when the amino group is located at the para position relative to the carboxyl group. PABA is commonly used as a sunscreen agent, as it absorbs ultraviolet light, and is also found in some vitamins and bacteria. It has various applications in pharmaceuticals, dyes, and chemical synthesis.
Aminobisphosphonates are a class of drugs used primarily to treat bone disorders such as osteoporosis, Paget's disease, and certain types of cancer that can cause bone destruction. They work by inhibiting the activity of cells responsible for breaking down bone tissue, thereby increasing bone density and reducing the risk of fractures. Examples of aminobisphosphonates include alendronate, zoledronic acid, and pamidronate.
Aminobutanoic acid, also known as gamma-aminobutyric acid (GABA), is an amino acid that functions as a neurotransmitter in the human nervous system. It plays a crucial role in regulating neuronal activity by inhibiting the firing of neurons, thus promoting relaxation and reducing anxiety. GABA is not used in protein synthesis like other amino acids but has significant physiological effects on the brain.
Aminobutyric acid, also known as gamma-aminobutyric acid (GABA), is an amino acid that functions as a neurotransmitter in the human brain. It plays a key role in regulating neuronal activity and is responsible for reducing excitement or inhibiting the firing of neurons. GABA helps to promote relaxation, reduce anxiety, and maintain a stable nervous system.
Aminocaproic acid is a medication used to prevent or control excessive bleeding (hemorrhage) by inhibiting the breakdown of blood clots. It belongs to a class of drugs called antifibrinolytic agents, which work by slowing down the action of enzymes that break down blood clots. This can be useful in conditions like heavy menstrual bleeding, bleeding disorders, or after certain surgical procedures.
Aminocyclitols are a group of compounds that contain a cyclitol (a cyclic sugar alcohol) moiety combined with an amino group. They are often found in natural products, particularly in some antibiotics and have shown antibacterial, antifungal, or other pharmacological activities. Examples include the antibiotic streptomycin, which contains an aminocyclitol component.
