Caulerpa Cupressoides
''Caulerpa cupressoides'', commonly known as cactus tree alga, is a species of seaweed in the ''Caulerpaceae'' family. Green alge of ''Caulerpa'' genus are salty and pungent in style and are consumed by several marine cultures around the world. Description The plant has runners that are overlaid by sand rising up to thick stalks that split into heavy upright branches that are in turn lined with rows of short think branchlets. The length can vary from with a tall slender habit to a short bushy habit. It is a coenocytic species that grows well in shallow protected areas with sandy bottoms. Distribution It is found around much of the world including the Americas between Florida and Brazil including most of the islands of the Caribbean. Both coasts of Africa as far south as South Africa and many of the islands in Atlantic, Indian and Pacific Oceans. Found through much of Asia and in Australia it is found in Queensland and in Western Australia along the coast in a large area extend ...

Cardioprotection
Cardioprotection includes all mechanisms and means that contribute to the preservation of the heart by reducing or even preventing myocardial damage. Mechanisms Cardioprotection encompasses several regimens that have shown to preserve function and viability of cardiac muscle cell tissue subjected to ischemic insult or reoxygenation. Cardioprotection includes strategies that are implemented: * before an ischemic event (preconditioning, PC), * during an ischemic event (perconditioning, PerC), * after the event and during reperfusion (postconditioning, PostC). These strategies can be further stratified by performing the intervention locally or remotely, creating classes of conditioning known as remote ischemic PC (RIPC), remote ischemic PostC and remote ischemic PerC. Classical (local) preconditioning has an early phase with an immediate onset lasting 2–3 hours that protects against myocardial infarction. The early phase involves post-translational modification of preexist ...

Anti-obesity Medication
Anti-obesity medication or weight loss medications are pharmacological agents that reduce or control excess body fat. These medications alter one of the fundamental processes of the human body, weight regulation, by: reducing appetite and consequently energy intake, increasing energy expenditure, redirecting nutrients from adipose to lean tissue, or interfering with the absorption of calories. Weight loss drugs have been developed since the early twentieth century, and many have been banned or withdrawn from the market due to adverse effects, including deaths; other drugs proved ineffective. Although many earlier drugs were stimulants such as amphetamines, in the early 2020s, GLP-1 receptor agonists became popular for weight loss. The medications liraglutide, naltrexone/bupropion, orlistat, semaglutide, and tirzepatide are approved by the US Food and Drug Administration (FDA) for weight management in combination with reduced-calorie diet and increased physical activi ...

Immunostimulant
Immunostimulants, also known as immunostimulators, are substances (drugs and nutrients) that stimulate the immune system usually in a non-specific manner by inducing activation or increasing activity of any of its components. One notable example is the granulocyte macrophage colony-stimulating factor. The goal of this stimulated immune response is usually to help the body have a stronger immune system response in order to improve outcomes in the case of an infection or cancer malignancy. There is also some evidence that immunostimulants may be useful to help decrease severe acute illness related to chronic obstructive pulmonary disease or acute infections in the lungs. Classification There are two main categories of immunostimulants: # Specific immunostimulants provide antigenic specificity in immune response, such as vaccines or any antigen. # Non-specific immunostimulants act irrespective of antigenic specificity to augment immune response of other antigen or stimulate component ...

Cytotoxicity
Cytotoxicity is the quality of being toxic to cells. Examples of toxic agents are toxic metals, toxic chemicals, microbe neurotoxins, radiation particles and even specific neurotransmitters when the system is out of balance. Also some types of drugs, e.g alcohol, and some venom, e.g. from the puff adder (''Bitis arietans'') or brown recluse spider (''Loxosceles reclusa'') are toxic to cells. Cell physiology Treating cells with the cytotoxic compound can result in a variety of prognoses. The cells may undergo necrosis, in which they lose membrane integrity and die rapidly as a result of cell lysis. The cells can stop actively growing and dividing (a decrease in cell viability), or the cells can activate a genetic program of controlled cell death (apoptosis). Cells undergoing necrosis typically exhibit rapid swelling, lose membrane integrity, shut down metabolism, and release their contents into the environment. Cells that undergo rapid necrosis in vitro do not have sufficient ...

Antimicrobial
An antimicrobial is an agent that kills microorganisms (microbicide) or stops their growth (bacteriostatic agent). Antimicrobial medicines can be grouped according to the microorganisms they are used to treat. For example, antibiotics are used against bacteria, and antifungals are used against fungi. They can also be classified according to their function. Antimicrobial medicines to treat infection are known as antimicrobial chemotherapy, while antimicrobial drugs are used to prevent infection, which known as antibiotic prophylaxis, antimicrobial prophylaxis. The main classes of antimicrobial agents are disinfectants (non-selective agents, such as bleach), which kill a wide range of microbes on surfaces to prevent the spread of illness, antiseptics which are applied to living tissue and help reduce infection during surgery, and antibiotics which destroy microorganisms within the body. The term ''antibiotic'' originally described only those formulations derived from living microorga ...

Antiviral Drug
Antiviral drugs are a class of medication used for treating viral infections. Most antivirals target specific viruses, while a broad-spectrum antiviral is effective against a wide range of viruses. Antiviral drugs are a class of antimicrobials, a larger group which also includes antibiotic (also termed antibacterial), antifungal and antiparasitic drugs, or antiviral drugs based on monoclonal antibodies. Most antivirals are considered relatively harmless to the host, and therefore can be used to pharmacotherapy, treat infections. They should be distinguished from virucides, which are not medication but deactivate or destroy virus particles, either inside or outside the body. Natural virucides are produced by some plants such as eucalyptus and Australian tea trees. Medical uses Most of the antiviral drugs now available are designed to help deal with HIV, Herpesviridae, herpes viruses, the hepatitis B and Hepatitis C, C viruses, and Influenzavirus A, influenza A and Influenzavirus ...

Herbivorous Fish
A herbivore is an animal anatomically and physiologically evolved to feed on plants, especially upon vascular tissues such as foliage, fruits or seeds, as the main component of its diet. These more broadly also encompass animals that eat non-vascular autotrophs such as mosses, algae and lichens, but do not include those feeding on decomposed plant matters (i.e. detritivores) or macrofungi (i.e. fungivores). As a result of their plant-based diet, herbivorous animals typically have mouth structures ( jaws or mouthparts) well adapted to mechanically break down plant materials, and their digestive systems have special enzymes (e.g. amylase and cellulase) to digest polysaccharides. Grazing herbivores such as horses and cattles have wide flat- crowned teeth that are better adapted for grinding grass, tree bark and other tougher lignin-containing materials, and many of them evolved rumination or cecotropic behaviors to better extract nutrients from plants. A large percent ...

Phytochemical
Phytochemicals are naturally-occurring chemicals present in or extracted from plants. Some phytochemicals are nutrients for the plant, while others are metabolites produced to enhance plant survivability and reproduction. The fields of extracting phytochemicals for manufactured products or applying scientific methods to study phytochemical properties are called ''phytochemistry''. An individual who uses phytochemicals in food chemistry manufacturing or research is a ''phytochemist''. Phytochemicals without a nutrient definition have no confirmed biological activities or proven health benefits when consumed in plant foods. Once phytochemicals in a food enter the digestion process, the fate of individual phytochemicals in the body is unknown due to extensive metabolism of the food in the gastrointestinal tract, producing phytochemical metabolites with different biological properties from those of the parent compound that may have been tested in vitro. Further, the bioavaila ...

Sesquiterpene
Sesquiterpenes are a class of terpenes that consist of three isoprene units and often have the molecular formula C15H24. Like monoterpenes, sesquiterpenes may be cyclic or contain rings, including many combinations. Biochemical modifications such as oxidation or rearrangement produce the related sesquiterpenoids. It is estimated (2006) that 3000 sesquiterpenes have been identified. Biosynthesis and examples The reaction of geranyl pyrophosphate with isopentenyl pyrophosphate results in the 15-carbon farnesyl pyrophosphate (FPP), which is an intermediate in the biosynthesis of sesquiterpenes such as farnesene. Cyclic sesquiterpenes are more common than cyclic monoterpenes because of the increased chain length and additional double bond in the sesquiterpene precursors. In addition to common six-membered ring systems such as the ones found in zingiberene and bisacurone, cyclization of one end of the chain to the other end can lead to macrocyclic rings such as humulene. ...
