Melanotan II
Melanotan II is a synthetic analogue of the peptide hormone α-melanocyte-stimulating hormone (α-MSH) that stimulates melanogenesis and increases sexual arousal. It was under development as drug candidate for female sexual dysfunction and erectile dysfunction but clinical development ceased by 2003, and as of 2018, no product containing melanotan II was marketed and all commercial development had ceased. Unlicensed, untested, or fraudulent products sold as "melanotan II" are found on the Internet, and purported to be effective as "tanning drugs", though side effects such as uneven pigmentation (it makes already uneven pigmentation more noticeable), new nevi (moles), and darkening or enlargement of existing moles have been reported and have led to medical authorities discouraging its use. There has been no scientific study into the long term and permanent side effects the use of this peptide may cause. Mechanism of action Melanotan II acts as a non-selective agonist of th ...

Flushing (physiology)
Flushing is to become markedly red in the face and often other areas of the skin, from various physiological conditions. Flushing is generally distinguished, despite a close physiological relation between them, from blushing, which is milder, generally restricted to the face, cheeks or ears, and generally assumed to reflect emotional stress, such as embarrassment, anger, or romantic stimulation. Flushing is also a cardinal symptom of carcinoid syndrome—the syndrome that results from hormones (often serotonin or histamine) being secreted into systemic circulation. Causes * abrupt cessation of physical exertion (resulting in heart output in excess of current muscular need for blood flow) * abdominal cutaneous nerve entrapment syndrome (ACNES), usually in patients who have had abdominal surgery * alcohol flush reaction * antiestrogens such as tamoxifen * atropine poisoning * body contact with warm or hot water (hot tub, bath, shower) * butorphanol reaction with some narcotic an ...

Cosmopolitan (magazine)
''Cosmopolitan'' is an American monthly fashion and entertainment magazine for women, first published based in New York City in March 1886 as a family magazine; it was later transformed into a literary magazine and, since 1965, has become a women's magazine. ''Cosmopolitan'' is one of the best-selling magazines and is directed mainly towards a female audience. Jessica Pels is the magazine's current editor-in-chief. Formerly titled ''The Cosmopolitan'' and often referred to as ''Cosmo'', throughout the years, ''Cosmopolitan'' has adapted its style and content. Its current incarnation was originally marketed as a woman's fashion magazine with articles on home, family, and cooking. Eventually, editor-in-chief Helen Gurley Brown changed its attention to more of a women empowerment magazine. Nowadays, its content includes articles discussing relationships, sex, health, careers, self-improvement, celebrities, fashion, horoscopes, and beauty. ''Cosmopolitan'' is published by New York ...

Amide
In organic chemistry, an amide, also known as an organic amide or a carboxamide, is a compound with the general formula , where R, R', and R″ represent organic groups or hydrogen atoms. The amide group is called a peptide bond when it is part of the main chain of a protein, and an isopeptide bond when it occurs in a side chain, such as in the amino acids asparagine and glutamine. It can be viewed as a derivative of a carboxylic acid () with the hydroxyl group () replaced by an amine group (); or, equivalently, an acyl (alkanoyl) group () joined to an amine group. Common examples of amides are acetamide (), benzamide (), and dimethylformamide (). Amides are qualified as primary, secondary, and tertiary according to whether the amine subgroup has the form , , or , where R and R' are groups other than hydrogen. The core of amides is called the amide group (specifically, carboxamide group). Amides are pervasive in nature and technology. Proteins and important plastics l ...

Hydroxyl Group
In chemistry, a hydroxy or hydroxyl group is a functional group with the chemical formula and composed of one oxygen atom covalently bonded to one hydrogen atom. In organic chemistry, alcohols and carboxylic acids contain one or more hydroxy groups. Both the negatively charged anion , called hydroxide, and the neutral radical , known as the hydroxyl radical, consist of an unbonded hydroxy group. According to IUPAC definitions, the term ''hydroxyl'' refers to the hydroxyl radical () only, while the functional group is called a ''hydroxy group''. Properties Water, alcohols, carboxylic acids, and many other hydroxy-containing compounds can be readily deprotonated due to a large difference between the electronegativity of oxygen (3.5) and that of hydrogen (2.1). Hydroxy-containing compounds engage in intermolecular hydrogen bonding increasing the electrostatic attraction between molecules and thus to higher boiling and melting points than found for compounds that lack this func ...

Bremelanotide
Bremelanotide, sold under the brand name Vyleesi, is a medication used to treat low sexual desire in women. Specifically it is used for low sexual desire which occurs before menopause and is not due to medical problems, psychiatric problems, or problems within the relationship. It is given by an injection just under the skin of the thigh or abdomen. Common side effects include nausea, pain at the site of injection, and headache. It may also cause a temporary increase in blood pressure and decrease in heart rate after each dose, and darkening of the gums, face, and breasts. The medication is a peptide and acts by activating the melanocortin receptors. Bremelanotide was approved for medical use in the United States in 2019. It was developed by Palatin Technologies.

Technology Transfer
Technology transfer (TT), also called transfer of technology (TOT), is the process of transferring (disseminating) technology from the person or organization that owns or holds it to another person or organization, in an attempt to transform inventions and scientific outcomes into new products and services that benefit society. Technology transfer is closely related to (and may arguably be considered a subset of) knowledge transfer. A comprehensive definition of technology transfer today includes the notion of collaborative process as it became clear that global challenges could be resolved only through the development of global solutions. Knowledge and technology transfer plays a crucial role in connecting innovation stakeholders and moving inventions from creators to public and private users. Intellectual property (IP) is an important instrument of technology transfer, as it establishes an environment conducive to sharing research results and technologies. Analysis in 2003 showe ...

Sunless Tanning
Sunless tanning, also known as UV filled tanning, self tanning, spray tanning (when applied topically), or fake tanning, refers to the effect of a suntan without exposure to the Sun. Sunless tanning involves the use of oral agents (carotenids), or creams, lotions or sprays applied to the skin. Skin-applied products may be skin-reactive agents or temporary bronzers (colorants). The popularity of sunless tanning has risen since the 1960s after health authorities confirmed links between UV exposure (from sunlight or tanning beds) and the incidence of skin cancer. Global self-tanning product market size is projected to increase by 5.9% from 2019 to 2025. The convenience and effective results continue to boost demand and interest in products. The chemical compound dihydroxyacetone (DHA) is used in sunless tanning products in concentrations of 3%-5%. DHA concentration is adjusted to provide darker and lighter shades of tan. The reaction of keratin protein present in skin and DHA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anorexia (symptom)
Anorexia is a medical term for a loss of appetite. While the term in non-scientific publications is often used interchangeably with anorexia nervosa, many possible causes exist for a loss of appetite, some of which may be harmless, while others indicate a serious clinical condition or pose a significant risk. Anorexia is a symptom, not a diagnosis. Anorexia is not to be confused with the mental health disorder anorexia nervosa. Because the term 'anorexia' is often used as a short-form of anorexia nervosa, to avoid confusion a provider must clarify to a patient whether they are simply referring to a decreased appetite or the mental health disorder. Anyone can manifest anorexia as a loss of appetite, regardless of their gender, age, or weight. The symptom also occurs in other animals, such as cats, dogs, cattle, goats, and sheep. In these species, anorexia may be referred to as inappetence. As in humans, loss of appetite can be due to a range of diseases and conditions, as well as ...

Yawning
A yawn is a reflex lasting 4-7 seconds, and is characterized by a long inspiratory phase with gradual mouth gaping, followed by a brief climax (or acme) with muscle stretching, and a rapid expiratory phase with muscle relaxation. For fish and birds, this is described as gradual mouth gaping, staying open for at least 3 seconds and subsequently a rapid closure of the mouth. Almost all vertebrate animals, including mammals, birds, reptiles, amphibians, and even fish, experience yawning. The study of yawning is called chasmology. Yawning (oscitation) most often occurs in adults immediately before and after sleep, during tedious activities and as a result of its contagious quality. It is commonly associated with tiredness, stress, sleepiness, boredom, or even hunger. In humans, yawning is often triggered by the perception that others are yawning (for example, seeing a person yawning, or talking to someone on the phone who is yawning). This is a typical example of positive feedb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
