Anastrozole (Arimadex) and letrozole (Femara) are the examples of non-steroidal AIs, which are derived from antifungal drugs, such as ketonazole. These two compounds bind to the heme moiety of aromatase, and therefore inhibitor fungal P450 enzymes. The non-steroidal AIs are generally reversible, and a reduction of estrogen synthesis depends on the continuous presence of the drug
In addition, AAS in supratherapeutic doses could slightly impair the immune system functions while reducing an individual's resistance to certain types of infections. AAS is also well tolerated in the renal system. Largely excreted from the body through the kidneys, and no inherent strong toxicity in process. However, steroids are slightly weather resistant to infection in men and it appears to be caused by testosterone. Testosterone is a immunosuppressive hormone. Also, androgens could modulate the immune system and the effects on the immune system may vary depending on the particular conditions and how the individual’s body reacts to the steroids. AAS is also used as a supportive treatment for compromised kidney functions and, AAS
Sexually transmitted diseases in the United States are on the rise after several years of decline. Three STD’s in particular are a concern to health care providers: gonorrhea, chlamydia, and syphilis. The CDC reports that the reports for chlamydia are up 27% from four years ago (Center for Disease Control and Prevention, 2016). The numbers are even more startling when looking at these three STD’s in St. Louis city. I ask these questions when writing the brief: 1.) Does St. Louis address these rising concerns differently than other metropolitan areas in the nation? And 2.) What have other cities done in the United States to combat the growing number of teenagers and young adults with STDs.
Most people think of anti-bacterial chemicals as their protector from dangerous pathogens, but in reality the chemicals can bring some side effects. A study conducted in South Korea stated that triclosan, a chemical anti-bacterial agent, can disrupt the hormonal system. Triclosan is able to mimic estrogen hormone (feminization hormone) thus will alter the normal production of other hormones, such as testosterone. Changes in the level of production will cause an imbalance in the endocrine system and the imbalance will support the growth of abnormal cells. In women, abnormal cell growth is strongly associated with breast cancer cells. This conclusion has been demonstrated in a series of experiments on two groups of laboratory mice.
Estrogens are vital for the regulation of sex hormones, and are known to proliferate certain forms of cancers. For this reason, estrogens are a recognized target for inhibition of hormone depended diseases like breast cancer, and aromatase inhibitors (AIs) like letrozole and anastrozole are of interest as they will lower the levels of estrogens. Both letrozole and anastrozole are currently indicated for the treatment of post-menopausal women with breast cancer.
Anastrozole (Arimidex) is the aromatase inhibitor of choice. The drug is appropriately used when using substantial amounts of
Anabolic steroids officially known as anabolic-androgenic steroids (AAS), are drugs which mimic the effects of the male steroids testosterone and dihydrotestosterone. They are widely distributed in nature and have varying functions essential to life. Steroids increase protein synthesis within cells, which results in the buildup of cellular tissue, especially in muscles. Also, anabolic steroids have androgenic and virilizing properties, including the development and maintenance of masculine characteristics such as the growth of the vocal cords and body hair.Anabolic steroids were first isolated, identified and synthesized in the 1930s, and are now used therapeutically in medicine to stimulate bone growth and appetite, induce male puberty, and
Spironolactone is a nonselective aldosterone receptor antagonist marketed since the 1960s and bears structural similarity to progesterone resulting in sex steroid receptor cross reactivity. This is responsible for anti-androgen and anti-progesterone adverse effects seen in treated individuals. Canrenone, marketed as principle active metabolite of spironolactone, is devoid of significant first pass metabolism and has a substantially longer t ½ as compared to the parent molecule (16.5 hours vs 1.4 hours). It has also been reported to have a lower incidence of antiandrogenic adverse reactions despite being a non-selective MRA. Eplerenone, a spironolactone derivative, in contrast is a selective aldosterone receptor antagonist with lower affinity for the progesterone and androgen receptors and consequently is devoid of related adverse effects. Eplerenone is primarily metabolized in the liver by cytochrome P450 (CYP3A4 isoenzyme) and is therefore subject to interactions with CYP3A4 inhibitors as well as inducers. It has a plasma half-life of 4-6 hours, and steady state levels are usually achieved 48 hours after treatment initiation.
Gonorrhea is a STD found in the genitals, rectum or throat. Gonorrhea is commonly called the clap. The clap is commonly found in boys and girls around the age 15-24. The clap in men have the symptoms of; swollen testicles, hurts to pee, and discolored discharge. For females is; hurts to urinate, bleeding between periods, and increased discharge during periods. If you have it in the rectum, it hurts to poop. Gonorrhea can only be passed on through sex, but can also be passed on through mother to child. Gonorrhea can be cured within 7
Athletes that use this drug typically take it with testosterone to help side effects such as a loss of sex drive, depression, and moodiness. The Sixth steroid is called Oxymetholone, also known as Anadrol. This drug comes in a tablet form. Anadrol improves red blood cell production and increases the amount of hemoglobin that helps to treat anemia. Although the FDA approves Anadrol, this drug still has serious side effects. These include breast cancer in males and females and reabsorption of the bone. The seventh steroid is called Oxandrolone, otherwise known as Anavar. This drug is used mainly in bodybuilders because of its strong anabolic affect.
Be that as it may, it can't really change over to estrogen (by means of the aromatase chemical). It's additionally not a progestin or a compound with progenestic action – which implies the estrogenic reactions connected to Anadrol are strange in nature. It's been thought the reactions are caused by the way that Anadrol may animate the estrogen receptor without really being changed over to estrogen. In any case, as most steroids, far reaching therapeutic research on its techniques for activity is deficient.
The potential therapeutic value of anabolic activity of testosterone in various catabolic conditions have led to the synthesis of many derivatives which aims to prolong its biological activity, developing products ever less androgenic and more anabolic, called androgenic anabolic steroids. Therefore, anabolic steroids are a subset of androgens, namely synthetic testosterone derivatives, (Kam, Yarrow, 2005).
A little bit about steroids: aromatizing and not only.Prolonged use of steroids can lead to increased levels of estradiol in the blood and as a consequence of it - to aromatization. I note here that this property have only the so-called aromatizable steroids. Testosterone is considered to have the biggest incline to this process, of course. The second place occupies such a steroid as methandrostenolone. Boldenone and flyuksimetreon have more weak property of aromatization.There are steroids that can be converted to estradiol without the process of aromatization, these include nandrolone, norethandrolone and ethylestrenol. However, it makes no significant relief, and the level of estrogen
Anabolic steroids are a group of organic compounds and synthetic variants of the male sex hormone testosterone. The proper term for these compounds is anabolic-androgenic steroids (abbreviated AAS)—“anabolic” referring to muscle-building and “androgenic” referring to increased male sexual characteristics (Pope and Brower, 2005). They are synthesized in the body from cholesterol in the Leydig cells in the testes, and in smaller amounts in the adrenal glands of both males and females and in female ovaries (Talih, Fattal and Malone, 2007). Anabolic steroids should not be confused with other types of steroids such as corticosteroids (e.g., cortisone or prednisone), which have no anabolic effects and therefore have little abuse potential (Pope and Brower, 2005; Sheffield-Moore and Urban, 2004).
Gonorrhea, one of the fastest growing STDs with almost 400,000 new cases per year in the U.S., is a common bacterial illness that is transmitted sexually and perinatally (CDC, 2016). The disease primarily affects the mucous membranes of the lower genital tract, but can also reach the rectum, oropharynx, and the conjunctivae (Tan et al., 2008). Mucous membranes, rich in mucous glands, line body passages and cavities, and within men, this includes the urethra, while within women, it includes the vagina (Miriam-Webster Dictionary, 2017). Currently, there is a working antibiotic for the bacteria, though early recognition is required for its use, and at the moment, a vaccine is being worked on for the disease (Kollar et al., 2005).
HIV is a virus that affects all parts of the globe. However, there are two major global epidemics. The first being in the west and developing countries. In these areas the pattern of infection is found in certain groups. These groups being “drug injectors, gay men and prostitutes” (Pisani p. ) This epidemic is known as the “concentrated epidemic”. This particular pattern HIV spreads rapidly in a concentrated groups. This is because you are most likely to pass on the virus when you are in the first stage of HIV. In a concentrated tight knit group of people who are having several sex partners and sharing needles with others it is easy for the virus to be transmitted. The other epidemic pattern is seen in east and southern Africa as well as some parts of east Africa and the Caribbean. This pattern is also known as “generalised epidemic”. This pattern is different because HIV is in the general population appose to a concentrated population.
