A Cochrane review found that while it is an effective treatment for shigellosis it also produces more significant adverse effects than other antibiotic drugs. [43] Staphylococcus aureus infections: No: No: No: In vitro and in vivo activity against both non-resistant and methicillin-resistant Staphylococcus aureus (MRSA) infections. [44] [45 ...
Skin (percutaneous, dermal) absorption is the transport of chemicals from the outer surface of the skin both into the skin and into circulation. Skin absorption relates to the degree of exposure to and possible effect of a substance which may enter the body through the skin. Human skin comes into contact with many agents intentionally and ...
The third type is the xanthophores which contains yellow pigments in the forms of carotenoids. The various colors are made by the combination of the different layers of the chromatophores. These cells are usually located beneath the skin or scale the animals. There are two categories of colors generated by the cell – biochromes and ...
Absorption. Sulfamethoxazole is well-absorbed when administered topically. It is rapidly absorbed when it is orally administered. [1] Distribution. Sulfamethoxazole distributes into most body tissues as well as into sputum, vaginal fluid, and middle ear fluid. [8] [11] It also crosses the placenta. About 70% of the drug is bound to plasma proteins.
Chromatophores in the skin of a squid. Chromatophores are cells that produce color, of which many types are pigment-containing cells, or groups of cells, found in a wide range of animals including amphibians, fish, reptiles, crustaceans and cephalopods. Mammals and birds, in contrast, have a class of cells called melanocytes for coloration.
Bacteroides thetaiotaomicron is a common bacterium in the human gut microbiome that has evolved alongside humans to support digestion and general health. Over time, this bacterium developed the ability to break down complex carbohydrates into simple sugars, which helps the host species get more energy from the food it eats.
In recent years, the word detritus has also come to be used with aquariums (the word "aquarium" is a general term for any installation for keeping aquatic animals). When animals such as fish are kept in an aquarium, they produce substances such as excreta, mucus, and dead skin cast off during moulting. These substances naturally generate ...
Some antibiotics may also damage the mitochondrion, a bacteria-derived organelle found in eukaryotic, including human, cells. [52] Mitochondrial damage cause oxidative stress in cells and has been suggested as a mechanism for side effects from fluoroquinolones. [53] They are also known to affect chloroplasts. [54]
