Impotence: When You Can’t Get It Up is Getting You Down
Probably nothing devastates a man more than having a failure in the bedroom. Impotence or erectile dysfunction affects nearly 33 million men in the United States. You are not alone. Help is available for nearly every man who has erectile dysfunction.
Diet
According to the Urology Channel’s “Erectile Dysfunction: Natural/Alternative Treatments,” erectile dysfunction can be treated by eating right, drinking plenty of water and avoiding sugar, dairy and caffeine. They recommend to eat whole, fresh, unrefined and unprocessed foods, including vegetables, whole grains, soy, beans, seeds, nuts, olive oil and cold-water fish such as salmon and tuna.
Taking your vitamins can also help; the Urology Channel suggests supplements such as flaxseed, and in particular vitamins C, E and the mineral zinc. These vitamins and supplements help bolster the vascular system, which is an important part of good sexual health.
Exercise
Since sexual health relies on the vascular system, a strong heart…

Drug development can be a gas
Pharmaceutical and biotech industries are heavily dependent on gas mixtures to grow biological cultures
The pharmaceutical and biotech industries rely heavily on industrial gases for applications such as supercritical fluid chromatgraphy and lyophilisation. Gas supply systems theefore need to offer high purity and traceability through the supply chain

Everolimus (RAD-001) is the 40-O-(2-hydroxyethyl) derivative of sirolimus and works similarly to sirolimus as an inhibitor of mammalian target of rapamycin (mTOR).
It is currently used as an immunosuppressant to prevent rejection of organ transplants and treatment of renal cell cancer and other tumours. Much research has also been conducted on everolimus and other mTOR inhibitors for use in a number of cancers.
It is marketed by Novartis under the tradenames Zortress (USA) and Certican (Europe and other countries) in transplantation medicine, and Afinitor in oncology.
GSK’s Votrient meets primary objective in Phase III ovarian cancer trial
pazopanib
GlaxoSmithKline’s (GSK) Votrient (pazopanib) has met the primary objective of a statistically significant improvement in the time to disease progression or death that is the progression-free survival (PFS) against placebo in Phase III ovarian cancer..
Pazopanib (trade name Votrient) is a potent and selective multi-targeted receptortyrosine kinase inhibitor of VEGFR-1, VEGFR-2, VEGFR-3, PDGFR-a/β, and c-kit that blocks tumor growth and inhibits angiogenesis. It has been approved for renal cell carcinoma and soft tissue sarcoma by the U.S. Food and Drug Administration.Pazopanib may also be active in ovarian cancer Pazopanib also appears effective in the treatment of non-small cell lung carcinoma.
New Drug Target Identified For Treating Deadly Form Of Leukemia
A research team in Singapore has identified a promising drug target for the treatment of patients with terminal-stage chronic myeloid leukemia (CML).
AsianScientist (Jun. 4, 2013) – A research team in Singapore has identified ways to inhibit the function of a key protein linked to stem cell-like behavior in terminal-stage chronic myeloid leukemia (CML). The discovery makes it possible to develop drugs that may extend the survival of patients suffering from this deadly form of leukemia.read all this at

Flamel Technologies today announced that the U.S. Food and Drug Administration (FDA) has approved the company’s New Drug Application (NDA) for Bloxiverz (neostigmine methylsulfate)

Flamel Technologies Announces FDA Approval of Bloxiverz
06/03/2013 — Flamel Technologies today announced that the U.S. Food and Drug Administration (FDA) has approved the company’s New Drug Application (NDA) for Bloxiverz (neostigmine methylsulfate), a drug used intravenously in the operating room for the reversal of the effects of non-depolarizing neuromuscular blocking agents after surgery. Flamel expects to launch Bloxiverz in July 2013 in 0.5 and 1.0 mg/mL strengths
Chemistry
Neostigmine, N,N,N-trimethyl-meta-(dimethylcarbomoyloxy)-phenylammonium methylsulfonate, which can be viewed as a simplified analog of physostigmine, is made by reacting 3-dimethylaminophenol with N-dimethylcarbamoyl chloride, which forms the dimethylcarbamate, and its subsequent alkylation using dimethylsulfate forming the desired compound. 
- J.A. Aeschlimann, U.S. Patent 1,905,990 (1933).
Neostigmine shows notable UV/VIS absorption at 261nm, 267nm, and 225nm.
Neostigmine’s 1H NMR Spectroscopy reveals shifts at: 7.8, 7.7, 7.4, 7.4, 3.8, and 3.1 parts per million. The higher shifts are due to the aromatic hydrogens. The lower shifts at 3.8ppm and 3.1ppm are due to the electronic withdrawing nature of the tertiary and quarterary nitrogen, respectively.

An experimental drug from Merck that unleashes the body’s immune system significantly shrank tumors in 38 percent of patients with advanced melanoma, putting the company squarely in the race to bring to market one of what many experts view as the most promising class of drugs in years.
The drugs are attracting attention here at the annual meeting of the American Society of Clinical Oncology, even though they are still in the early stage of testing. Data from drugs developed by Bristol-Myers Squibb and by Roche had already been released.
The drugs work by disabling a brake that prevents the immune system from attacking cancer cells. The brake is a protein on immune system cells called programmed death 1 receptor, or PD-1.
Merck’s study, which was presented here Sunday and also published in the New England Journal of Medicine, involved 135 patients. While tumors shrank in 38 percent of the patients over all, the rate was 52 percent for patients who got the highest dose of the drug, which is called lambrolizumab, or MK-3475.
