Fluconazole is a synthetic antimycotic drug of the triazole class of compunds. The drug is sold under the brand name Diflucan®. It is used orally and intravenously to treat yeast and other fungal infections.
DNA is a polymer made of monomers called nucleotides
1. When estrogen is not balanced by progesterone, it can produce weight gain, headaches, bad temper, chronic fatigue and loss of interest in sex - all of which are part of the clinically recognized premenstrual syndrome.
2. Not only has it been well established that estrogen dominance encourages the development of breast cancer thanks to estrogen's proliferative actions, it also stimulates breast tissue and can trigger fibrocystic breast disease - a condition which wanes when natural progesterone is introduced to balance the estrogen.
3. Excess estrogen implies a progesterone deficiency. This, in turn, leads to a decrease in the rate of new bone formation in a woman's body by the osteoblasts - the cells responsible for doing this job. Although most doctors are not yet aware of it, this is the prime cause of osteoporosis.
4. Estrogen dominance increases the risk of fibroids. One of the interesting facts about fibroids is that, regardless of the size, fibroids commonly atrophy once menopause arrives and a woman's ovaries are no longer making estrogen. Doctors who commonly use progesterone with their patients have discovered that giving a woman natural progesterone may cause fibroids to atrophy.
5. In estrogen-dominant menstruating women where progesterone is not peaking and falling in a normal way each month, the ordered shedding of the womb lining doesn't take place. Menstruation becomes irregular. This condition can usually be corrected by making lifestyle changes and using a natural progesterone product. It is easy to diagnose by having a doctor measure the level of progesterone in the blood at certain times of the month.
6. Endometrial cancer (cancer of the womb) develops only where there is estrogen dominance or unopposed estrogen. This, too, can be prevented by the use of natural progesterone. The use of the synthetic progestins may also help prevent it, which is why a growing number of doctors no longer give non-human estrogens without combining them with progesterone drug during HRT. However, all synthetic progestins have side effects.
7. Water logging of the cells and an increase in intercellular sodium, which predispose a woman to high blood pressure or hypertension, frequently occur with estrogen dominance. These can also be side effects of progestins use. A natural progesterone cream often resolves this problem.
8. The risk of stroke and heart disease is increased dramatically when a woman is estrogen-dominant.
BACKGROUND: Neisseria meningitidis is an important human commensal and pathogen that causes several thousand deaths each year, mostly in young children. How the pathogen replicates and causes disease in the host is largely unknown, particularly the role of metabolism in colonization and disease. Completed genome sequences are available for several strains but our understanding of how these data relate to phenotype remains limited. RESULTS: To investigate the metabolism of N. meningitidis we generated and selected a representative Tn5 library on rich medium, a minimal defined medium and in human serum to identify genes essential for growth under these conditions. To relate these data to a systems-wide understanding of the pathogen's biology we constructed a genome-scale metabolic network: Nmb_iTM560. This model was able to distinguish essential and non-essential genes as predicted by the global mutagenesis. These essentiality data, the library and the Nmb_iTM560 model are powerful and widely applicable resources for the study of meningococcal metabolism and physiology. We demonstrate the utility of these resources by predicting and demonstrating metabolic requirements on minimal medium such as a requirement for PEP carboxylase, and by describing the nutritional and biochemical status of N. meningitidis when grown in serum, including a requirement for both the synthesis and transport of amino acids. CONCLUSIONS: This study describes the application of a genome scale transposon library combined with an experimentally validated genome-scale metabolic network of N. meningitidis to identify essential genes and provide novel insight to the pathogen's metabolism both in vitro and during infection.
