Eating cranberries can make you live longer, study suggests

Atasteofcreole's Blog

Fruit flies fed sugar and cranberry extract in a recent study lived 25% longer than those fed only sugar. Scientists haven’t studied the effects on humans, but the same could be true. They say it’s the fruit’s antioxidant properties that prolong life.

A new study finds that cranberries have antioxidant properties that may prolong your life.

In new research to be published in the February 2014 issue of Experimental Gerontology, scientists have found that eating cranberries can extend your life significantly. The caveat: the study was conducted on fruit flies, not humans. A team from National Institute on Aging in Baltimore fed the flies sugar supplemented by two percent cranberry extract during three biological stages of their lives, which correspond in humans with young adulthood, middle age, and old age, the Wall Street Journal reports.

Findings showed that younger flies fed cranberry extract lived 25 percent longer than the…

Vitamin B7- Biotin

Medical Revolt

Yet one more B vitamin (and more to come) Vitamin B7 also known as Vitamin H or Biotin is also important in metabolism and the production of fatty acids and cell growth. It assists in the transfer of carbon dioxide in the body and aids in maintaining normal blood sugar. It also assists in normal adrenal function and for maintaining a healthy nervous system and metabolism

Most of our biotin actually does not come directly from food but from the bacteria in our intestines. It is found in many foods but only in small amounts. Foods that are rich in biotin include green leafy vegetables such as swiss chard and organ meats such as liver. The recommended daily allowance is 30 mcg/day.

Low biotin levels have been found in some populations most notably alcoholics, people who have had part of their stomach removed, the elderly and those with low stomach acid. Consumption…

University of Toronto researchers have developed safer, cheaper and more environmentally-friendly techniques to produce compounds commonly used in drugs and perfumes.

Researchers used the  new techniques to create active, iron-based catalysts. These catalysts are needed to produce certain compounds used in the drug and perfume industries.  read all here

US HERBS –DAMIANA, reported to be an aphrodisiac, stimulant, mood elevator

New Drug Approvals


Damiana (Turnera diffusa) is reported to be an aphrodisiac, stimulant, mood elevator, and “tonic,” and has been in use in the United States since 1874. Despite a paucity of research, it has reported testosterogenic activity, which may account for its traditional use by the Mayan people of Central America for enhancing sexual function in men and women.

Turnera diffusa, known as damiana, is a shrub native to southwestern Texas in the United States,[3] Central AmericaMexicoSouth America, and the Caribbean. It belongs to the family Passifloraceae.[2]

Damiana is a relatively small shrub that produces small, aromatic flowers. It blossoms in early to late summer and is followed by fruits that taste similar to figs. The shrub is said to have a strong spice-like odor somewhat like chamomile, due to the essential oils present in the plant.

Cross-Coupling Triple Play Green Chemistry: Popular reactions using specialized boron reagents can now be run in water

In aqueous micelle solutions made using the surfactant TPGS-750-M, even unstable 2-pyridyl boronates readily undergo Suzuki-Miyaura cross-coupling.
Chemists have taken one of the most widely used reactions in organic synthesis—the Suzuki-Miyaura cross-coupling reaction—and made it even more versatile by melding it with an award-winning green chemistry technology. The new development will help researchers, particularly those working in drug discovery, expand the range of compounds that can be made using the cross-coupling approach and create safer and environmentally friendly processes that avoid organic solvents, excess reagents, and high temperatures.

CHINESE MEDICINE-Xuezhikang , A blood lipid regulator

New Drug Approvals


Xuezhikang, the extract of red yeast rice, has been widely used as a Chinese traditional medicine for the therapy of patients with cardiovascular diseases. It contains natural Lovastatin and its homologues, as well as unsaturated fatty acids, flavonoids, plant sterols and other biologically active substances

The product is a world-recognized blood lipid regulator, which is made by extracting from “specially-made red yeast rice”. It combines modern high-tech biotechnology with traditional Chinese medicine, which can safely and effectively regulate blood lipids in a comprehensive way with proven curative effects and reliable safety.

Pharmacological Effects: the product can reduce blood cholesterol, triglycerides, low density lipoprotein cholesterol, improve high density lipoprotein cholesterol, inhibit atherosclerotic plaque formation, and protect vascular endothelial cells; and inhibit lipid deposition in the liver. The large-scale evidence-based research has proven that long-term use of XUEZHIKANG can greatly reduce the risk of CHD occurrence and decrease the mortality. XUEZHIKANG…

Fermentation free bioethanol synthesis



Patent Number: US 8502001
Title: Production of alcohol from carbonaceous feedstock
Inventor(s): Daniel, Berian John; Gracey, Benjamin Patrick
Patent Assignee(s): BP P.L.C., UK
The invention relates to the process for conversion of ethanoic acid into ethanol characterized by the following steps, (a) introducing ethanoic acid and H2 into a primary hydrogenation unit in the presence of a precious metal-based catalyst to produce ethanol and Et ethanoate, (b) introducing Et ethanoate, from step (a), together with H2, into a secondary hydrogenation unit in the presence of a copper-based catalyst to produce ethanol, and (c) recovering ethanol from step (b).  Thus, in the primary reactor H2 and ethanoic acid with a molar ratio of 10/1 was passed over the palladium-silver-rhenium-iron catalyst at 230° and 2.0 MPa with a GHSV of 4343 h-1 to give a product showing conversion of ethanoic acid to Et groups recoverable as ethanol was 41.9 %, of which 19.7 % was as Et ethanoate, 21.6 % ethanol, 0.4 % ethanal and 0.2 % di-Et ether and the total conversion of ethanoic acid to products was 44.7 %, the selectivity of ethanoic acid to Et groups recoverable as ethanol was 93.8 %; in the secondary reactor H2 and Et ethanoate with a molar ratio of 10/1 was passed over the copper-based catalyst at 200° and 5.0 MPa with a GHSV of 4491 h-1, the conversion of Et ethanoate to Etgroups recoverable as ethanol was 69.5 %, the selectivity of Et ethanoate to Et groups recoverable as ethanol was 99.9%.

As bioethanol continues to be an important component of gasoline, a high–carbon efficiency, nonfermentative route becomes increasingly important. One idea under exploration is gasifying cellulosic feedstocks to biosynthesis gas (syngas) and then converting the gas to mixed alcohols. The second step, however, is problematic because the initial formation of methanol is equilibrium-limited, and very high pressures are required to obtain even modest yields of C2+ alcohols.

Inventors B. J. Daniel and B. P. Gracey disclose a technique for making ethanol from syngas with high carbon efficiency. Methanol is first made from syngas by using conventional process technology. (Whether the syngas is biobased, natural gas–based, or coal-based is irrelevant.) The methanol is then carbonylated to acetic acid, again with conventional technology.

The patent’s invention is the hydrogenation of acetic acid (HOAc) to a mixture of ethanol (EtOH) and ethyl acetate (EtOAc). The EtOAc is separated and hydrogenated in another reactor to give additional EtOH.

In the patent’s one example, hydrogen and HOAc in a 10:1 mol ratio are passed over a Pd–Ag–Rh–Fe catalyst in the primary reactor at 230 ºC, 2.0 MPa pressure, and a gaseous hourly space velocity (GHSV) of 4343 h–1. The HOAc conversion is 41.9%, of which 19.7% is EtOAc, 21.6% EtOH, 0.4% MeCHO, and 0.2% Me2O. The overall selectivity to ethyl groups that can be recovered as EtOH is 93.8%.

In the secondary reactor, hydrogen and the EtOAc from the primary reactor in a 10:1 mol ratio are passed over a copper-based catalyst at 200 ºC, 5.0 MPa, and a GHSV of 4491h-1. The conversion of EtOAc is 69.5%, and the selectivity to ethyl groups that can be recovered as EtOH is 99.9%. Overall, the selectivity to EtOH is a high 95.7% (BP PLC [London].
