UPDATE 1-African Barrick cuts FY production guidance

LONDON, July 27 (Reuters) – African Barrick Gold (ABG) (ABGL.L), which floated in London this year, has cut its full-year production guidance due to delays in accessing higher grade from its new Buzwagi mine in Tanzania.

It expects to produce 750,000-800,000 ounces of gold for the year, at a cash cost of $500-550 an ounce, down from its 800,000 to 850,000 ounce target.

ABG’s chief executive told Reuters in June that production this year would likely end up at the low end of its 800,000 to 850,000 ounce target after a slow ramp up at its new Buzwagi open pit mine. [ID:nLDE65L22D]

On Tuesday, the FTSE 100 miner said first-half attributable production was 356,208 ounces, up 23 percent year-on-year, at cash costs of $529 per ounce.

The miner reiterated that it expects higher grade primary sulphide ore to be increasingly mined in the second half and for production to rise at Buzwagi.

First-half net income jumped 217 percent from the year-earlier period to $99 million and the company said it plans to pay an interim dividend of 1.6 cents per share.

Shares in the FTSE 100 group closed on Monday at 550 pence, just below the IPO price. Gold prices XAU= rose 13 percent in the first half of 2010 to touch a record $1,264.90 an ounce in June on concern over euro zone sovereign debt levels. [GOL/]

The market has viewed the company, which has four producing gold mines in Tanzania, with some caution compared to its rivals and is looking for African Barrick to establish a track record of organic growth or make an acquisition elsewhere in Africa.

ABG, spun off on March 19 from its Canadian parent Barrick Gold Corp (ABX.TO), the world’s largest gold miner, after raising 581 million pounds via an initial public offering at 575 pence a share.

Barrick Gold will announce its second-quarter results on Thursday. [ID:nN22125838]

Rotten eggs may pave way for safer anti-inflammatory drugs

Washington, May 21 (ANI): Rotten eggs might smell bad, but their odour can provide a new range of safer and effective anti-inflammatory drugs, say researchers.

A new study from Peninsula Medical School in Exeter has revealed that a molecule, which releases hydrogen sulphide – the gas that gives rotten eggs their characteristic smell- have an anti-inflammatory effect.

The gas has recently been found to be produced naturally in the body.

Until now, H2S could only be delivered in one go via a gas cylinder or through the use of sulfide salts, both of which are generally highly toxic, in addition to being foul smelling.

The research team investigated the role of H2S in endotoxic shock, which causes a fatal loss of blood pressure and extensive tissue inflammation.

They discovered that when H2S is delivered in a slow and sustained manner, a potent anti-inflammatory effect is produced.

The cell signalling molecules that drive inflammation, such as TNFa, IL-1, IL-6 and prostaglandins, were reduced while levels of the body’s own anti-inflammatory molecules (i.e. IL-10) were increased.

The team hopes that using H2S donating molecules to control H2S delivery in the body could pave the way for the development of novel approaches to the treatment of inflammatory disorders.

“We have known for a few years that H2S levels in tissue and blood are markedly elevated during inflammation,” said Dr. Matt Whiteman from the Peninsula Medical School, Exeter.

“It was assumed that this was a bad thing. However, our research is suggesting that H2S could be elevated as part of the body’s way to limit inflammation,” he added.

The study has been published in journal Free Radical Biology and Medicine. (ANI)

New eco friendly ‘bacteria’ coating protects metal against corrosion in seawater

Washington, March 30 (ANI): A team of researchers from Sheffield Hallam University, UK, has developed a new, environmentally friendly coating with the help of bacteria, which protects metals against corrosion in seawater.

Researcher Jeanette Gittens and colleagues have described how they had encapsulated spores s from a bacterium into a sol-gel coating, which then protected an aluminium alloy from microbial corrosion.

Microbially-influenced corrosion (MIC) of metals at sea is a big safety and financial problem caused by the production of damaging substances such as hydrogen sulphide by sulphate-reducing micro-organisms within biofilms on the surfaces.

Overall, it is estimated that corrosion costs the UK around 3-4 percent of GDP.

Existing anti-corrosion treatments are costly, ineffective and often include biocides and inhibitors that are toxic to aquatic life.

The corrosion-preventing bacteria occur naturally in the environment.

Incorporating its spores into the coating did not seem to affect their viability, as living cells were still found in the coating after more than six weeks in seawater.

The coating could also be heat cured at temperatures up to 90 degree Celsius.

According to Gittens, “Our results from laboratory studies and a field trial in the Thames estuary have shown that the bacteria-containing coating is substantially more effective in the prevention of corrosion than the sol-only coating.”

“We are investigating what causes the corrosion protection. We think it might be due to the immobilized bacteria producing antimicrobial agents which inhibit the growth of corrosion-causing microorganisms,” she added.

Additional trials are now planned or in progress in a variety of marine environments.(ANI)

Smell of rotten eggs is a big turn on for men!

London, Mar 3 (ANI): Rotten eggs might not be welcomed in a woman’s kitchen, but they can prove really useful under bed sheets, suggests a new study which found the smell of decaying eggs could make men randy.

According to research that could lead to new impotence treatments, the chemical behind the smell of rotten eggs helps men become aroused.

A gas called hydrogen sulphide – also released when eggs rot and from the exhausts of cars with catalytic converters – is given out by men just before they have sex.ollowing the study, researchers believe that it could be used to create a rival to Viagra.

“We found that hydrogen sulphide is involved in human penile erection,” The Telegraph quoted Professor Giuseppe Cirino of the University of Naples Federico II, as telling The Independent.

“The hydrogen sulphide pathway represents a new therapeutic target for erectile dysfunction and it should be possible in future to deliver drugs that either deliver hydrogen sulphide or that control the hydrogen sulphide production,” the expert added. (ANI)
