We will be happy to give our contribution towards the infrastructure development of Ghana," he said.The forthcoming two-day visit by the Chinese minister would afford the two countries to further cement, promote and syncretize the bilateral trade and economic corporation existing between them for more than five decades.The ambassador said the Chinese Embassy in Ghana is committed to offering quality service to Ghanaians engaging in bilateral exchanges and cooperation in different fields.Currently, China has supported the West African country in the construction of various roads, rails, school blocks, hospitals, among others.He called on the Chinese firms in Ghana to raise investments and take corporate social responsibilities in local communities where they are operating.

WASHINGTON, April 25 (Xinhua) -- Study by scientists at the Rockefeller University shows that anti-inflammatory drugs reduce the effectiveness of the most widely used class of antidepressant medications, the selective serotonin reuptake inhibitors (SSRIs), taken for depression and obsessive-compulsive disorder and anxiety disorders.This discovery, published online Monday in the Proceedings of the National Academy of Sciences, may explain why so many depressed patients taking SSRIs do not respond to antidepressant treatment and suggests that this lack of effectiveness may be preventable.The study may be especially significant in the case of Alzheimer's disease. Such patients commonly suffer from depression and unless this can be treated successfully, the course of the illness is likely to be more severe. Depression in the elderly is also a risk factor for developing Alzheimer's Disease and researchers have suggested that treating depression in the elderly might reduce the risk of developing the disease.In the recent study, investigators treated mice with antidepressants in the presence or absence of anti-inflammatory drugs. They then examined how the mice behaved in tasks that are sensitive to antidepressant treatment. They found that the mice's behavioral responses to antidepressants were inhibited by anti- inflammatory/analgesic treatments.They then confirmed these effects in a human population. Depressed individuals who reported anti-inflammatory drug use were much less likely to have their symptoms relieved by an antidepressant than depressed patients who reported no anti- inflammatory drug use. The effect was rather dramatic since, in the absence of any anti-inflammatory or analgesic use, 54 percent of patients responded to the antidepressant, whereas success rates dropped to approximately 40 percent for those who reported using anti-inflammatory agents."Many elderly individuals suffering from depression also have arthritic or related diseases and as a consequence are taking both antidepressant and anti-inflammatory medications. Our results suggest that physicians should carefully balance the advantages and disadvantages of continuing anti-inflammatory therapy in patients being treated with antidepressant medications," leader author Paul Greengard said.

SAN FRANCISCO, March 21 (Xinhua) -- Microsoft on Monday sued Barnes & Noble, claiming patent infringement by the largest book retailer in the United States.Microsoft said it filed legal actions on Monday in both the U.S. International Trade Commission and the U.S. District Court of the Western District of Washington against Barnes & Noble, as well as Foxconn and Inventec, two manufacturers of Barnes & Noble's devices.According to Microsoft, the actions focus on the patent infringement by Barnes & Noble's Nook e-reader and tablet, both of which run Google's Android operating system.The patents at issue cover a range of functionality embodied in Android devices that are essential to the user experience, including natural ways of interacting with devices by tabbing through various screens to find the information they need, surfing the Web more quickly and interacting with documents and e-books, Microsoft said in a press release."The Android platform infringes a number of Microsoft's patents, and companies manufacturing and shipping Android devices must respect our intellectual property rights," Horacio Gutierrez, Microsoft's corporate vice president and deputy general counsel, was quoted by the press release as saying.Writing in a separate company blog post, Gutierrez said that the latest actions bring to 25 the total number of Microsoft patents in litigation for infringement by Android smartphones, tablets and other devices.He noted that Microsoft has established a licensing program to address Android's ongoing infringement, and leading Android smartphone manufacturer HTC has taken a license under this program.Amazon.com also signed a patent license with Microsoft last year covering its Kindle e-reader, he added."Unfortunately, after more than a year of discussions, Barnes & Noble, Foxconn and Inventec have so far been unwilling to sign a license, and therefore, we have no other choice but to bring legal action to defend our innovations," Gutierrez said in the blog post.

BEIJING, March 11 (Xinhuanet) --Women who have a cup or more of coffee everyday may reduce their risk of stroke by as much as 25 percent, according to a new study in the Journal Stroke Thursday. This study, led by Swedish researcher Susanna Larsson of the Karolinska Institute in Stockholm, followed more than 34,000 Swedish women aged 49 to 83 who were free of heart disease. After 10-year of follow-up, there were 1,680 strokes, and the study found that those who drank at least one cup of coffee each day had a 22 to 25 percent lowered risk of stroke, compared with women who drank less.The study further suggested coffee can help prevent cognitive decline and can boost vision and heart health. It is also related to a reduced risk of liver cancer."We used to worry that (coffee) raises blood pressure and causes increased heart rate, but it appears to be less risky than we thought," said physician Claudette Brooks, spokesperson for the American Stroke Association. Now, exactly what it is about coffee that may lower stroke risk is unknown. But the researchers speculated that coffee might reduce inflammation, lower oxidative stress and help make the body more responsive to insulin.However, some experts kept skeptical about the real impact coffee would have on reducing the incidence of stroke."The problem with this type of study is that there are too many factors unaccounted for and association does not prove causality," Dr Larry B. Goldstein, director of the Duke Stroke Center at Duke University Medical Center said."Subjects were asked about their past coffee consumption in a questionnaire and then followed over time. There is no way to know if they changed their behavior," Goldstein added.In any case, the good news for coffee junkies is that at least drinking coffee don't increase women's risk of stroke.

NEW YORK, May 27 (Xinhua) -- U.S. stocks expanded gains on Friday ahead of the long Memorial Day weekend as surging commodity prices overcame disappointing economic data.European Central Bank Governing Council member George Provopoulos said that Greece might deal with its debt problem if it sticks to the aid program. That comment, which was considered as bullish by investors, drove the U.S. dollar weaker and led commodity prices surge on Friday.The stock market was driven by higher commodities prices, with thin trading volume ahead of the Memorial Day holiday, despite somewhat disappointing economic data on Friday.The Commerce Department said that both personal income and spending rose 0.4 percent in April, in line with market estimates. However, the rise in spending was the smallest in three months, suggesting the consumption situation was still weak.Meanwhile, pending home sales dropped 11.6 percent in April. The reading was a seven-month low. The market expectation was a drop of 1 percent.Moreover, the Thomson Reuters/University of Michigan Consumer Sentiment index came in above analysts' estimates. Concerns about higher gas prices and inflation had knocked the gauge down in March and April.Despite those disappointing data, analysts still held a bullish view toward the stock market. "Despite our near-term caution, we continue to see the S&P 500 reaching 1400 over the coming year," Alec Young, equity strategist of S&P Equity Research told Xinhua.According to Alex, while recent macro headwinds were raising questions about the sustainability of recent earnings momentum, he still believed that a downside trend of market was fairly limited and that the current weakness is more likely to be a correction, rather than the beginning of a new bear market."In our view, 2011 estimated EPS would have to be excessively optimistic to justify a bear market,"he added.The Dow Jones industrial average added 38.82 points, or 0.31 percent, to 12,441.58. The Standard & Poor's 500 was up 5.41 points, or 0.41 percent, to 1,331.10. The Nasdaq Composite Index rose 13.94 points, or 0.50 percent, to 2,796.86.
