Pharmacokinetics of Tamoxifen (Nolvadex) of Tamoxifen was investigated following an oral dose of 20 mg tablet in eight healthy female volunteers. Plasma samples were collected at different time intervals following drug administration, and analyzed for Tamoxifen concentration by HPLC method. The mean ± SE (mean ± standard deviation) of Tamoxifen at 0.5 hour was calculated as 4.87 ± 0.82 ng/ml which shows drugs penetration in the blood immediately after oral dose. The minimum effective concentration

Abraham Flexner Historians revere and are reviled by Abraham Flexner. He advocated educational reform to keep pace with European models, but he also clearly believed that any kind of medicine other than allopathic was inferior. Being revered by forward thinking educators made him the ideal front man for the moneyed chemical cartel in America. Historian Joseph Goulden describes the process this way: “Flexner had the ideas, Rockefeller and Carnegie had the money, and their marriage was spectacular

The fact that there are beings totally capable of feeling pain and appreciating that their lives are going to end is absolutely beyond dispute for any reasonable person. They are innocent, they are suffering. I am speaking, of course, of the 20,000 human beings who die from cancer each day. The only way to make new medicines and effective treatments for them, unfortunately, is to test them on animals. Animal research and testing is necessary to develop new medicines, treatments, and therapies for

Treatment of bosom malignancy Four sorts of standard treatment are utilized: 1. Surgery Most patients with bosom malignancy have surgery to expel the growth from the bosom. The fundamental objective of surgical treatment is to evacuate the growth and precisely characterize the phase of infection. Surgical choices extensively comprise of bosom protection treatment taken after by radiation treatment. Bosom rationing surgery, an operation to evacuate the growth however not the bosom itself,

Causes & Prevention Endometrial cancer can be caused by increased levels of estrogen. Estrogen is one of the main reasons because there is so much when a woman has never been pregnant, has late menopause, and early menstruation. Other causes can be Tamoxifen, a drug, inherited, polycystic ovary syndrome, body

Nuclear receptors are a class of receptors that have the ability to bind ligands, steroid and thyroid hormones, in order to mediate the expression of specific genes in a cell***. There are two types of nuclear receptors in the family, type one and type two. Type one receptors require a ligand to be bound to the receptor so activation can be initiated** by a conformational change of the ligand, travel to the nucleus and associate to inverted repeat hormone response elements in DNA. Type two receptors

have the ability to regenerate their heart up to 20% after amputation in about one month. The purpose of this experiment is to determine the importance and origin of former cardiomyocytes and how they serve a role in regeneration. A cre/lox plus tamoxifen system is used to manipulate genetic material in cardiomyocytes and determine its original lineage. A major key finding is that Zebrafish cardiac muscle cells minimally switch up their pattern of genetic expression to an earlier stage, which is seen

They are designed to attack molecular targets, whereas chemotherapy works rapidly killing normal and cancerous cells. The targeted cancer therapy ‘Tamoxifen citrate’ was discovered in 1966, but the first clinical trial approved by 1970 at the Christie Hospital in Manchester managing to increase survival rates for those suffering from breast cancer. Tamoxifen citrate is widely used to treat oestrogen receptor (ER) positive breast cancer that resulted in decreasing breast cancer. This was supported by

Thickened Endometrium The endometrium is the inner lining of the uterus. Its thickness varies with a woman’s age, reproductive stage and specific point of her menstrual cycle. A thickened endometrium may or may not be a normal finding, depending on various factors of a woman’s menstrual stage. To evaluate endometrial thickening, ultrasound or magnetic resonance imaging (MRI) may be used. Part 1: Normal Endometrial Thickness in Menstrual Cycle The endometrium normally changes in thickness and appearance

early twentieth century and then in the 1950s, her cancer is treated with both a mastectomy and radiation. The 1970s follow her surgery up with chemotherapy to reduce the chance of relapse and when her tumor tests positive for the estrogen receptor, Tamoxifen is also added to her treatment. It is hard to say for sure but it is estimated that seventeen to thirty years could have been added to her life. By the '90s it is discovered that Atossa has a gene mutation so her daughters are also tested as a way

Animal testing has been in existence for as long as recorded history. It has been used for various types of research, ranging from testing on mammals for understanding of blood circulation, which dates back to almost 1600 AD, to the introduction of the meningitis vaccine in 1992. It has given us loads of information regarding how to treat those who are ill or have diseases. Animal testing is taking us forward not only as a species, but as a civilization. There are multiple reasons why animals are

Pathologic grading is based on Modified Bloom Richardson scoring which utilizes three variables: gland-formation (tubularity), degree of variation in nuclear size and shape (pleomorphism), and ‘hyper chromatic figures’ as an estimate of proliferation(Bloom HJG et al 1957 and S. THORESENet al1982). The College of American Pathologists and the World Health Organization endorse this classification. The basic principle is summation of scores for the three variables, each of which is assigned from one

Folin–Ciocalteu reagent, gallic-acid, phloroglucinol, 1, 1-Diphenyl-2-picrylhydrazyl (DPPH), ascorbic acid and BHT were purchased from Sigma-aldrich, (Germany); sodium carbonate, YPD medium and Mueller-Hinton agar were purchased from Merck (Germany); Chloramphenicol, Ciprofloxacin and McFarland scale were purchase from Biomerieux (France). Methanol, n-Hexane and

In this essay you will read about how scientists from Perelman School of Medicine at the University of Pennsylvania are coming up with healthier ways for people to get a tan. I will explain how the body chemically changes it’s skin tone when exposed to natural sunlight and how skin tone varies upon all people. At the end of my essay I will share my own thoughts on tanning and the importance of taking caution while tanning. The article New Pathways That Control Skin Tanning, Lightening

20 years after her death. To all readers disappointment, her family didn’t even get a portion, or even a small percent of the money earned from using her cell line to make various medical advances. These include the polio vaccine, the cancer drug tamoxifen, chemotherapy, gene mapping, in vitro fertilization, and treatments for influenza, leukemia, and Parkinson’s disease (from article). Although Henrietta died, the adversity was not really faced by her, but by her family in not knowing about the cell
