Early Detection of Increased Thrombosis Risk
Siemens Healthcare has developed Innovance Antithrombin, a new test for determining congenital and acquired antithrombin deficiency. Insufficient levels of protein in blood can lead to increased thrombophilia. Reason: Antithrombin ensures balanced blood coagulation by reducing the activity of thrombin and coagulation factor Xa which are responsible for blood coagulation. Innovance Antithrombin detects insufficient antithrombin activity, enabling the early detection of an increased risk of thrombosis in patients. Innovance Antithrombin by Siemens Healthcare is a new chromogenic test for the automatic quantification of functionally active antithrombin in human citrated plasma. In contrast to antithrombin activity tests based on the inhibition of the coagulation factor thrombin, Innovance Antithrombin determines the activity of the antithrombin protein through the inhibition of coagulation factor Xa. This prevents distortion of the test result if a patient was given specific medication to prevent or treat thromboses, such as hirudin or other thrombin inhibitors. Innovance Antithrombin can be used with the automatic coagulation measuring devices from Siemens such as BCS and BCS XP as well as Sysmex CA-500, Sysmex CA-1500 and Sysmex CA-7000. The new test by Siemens is also suitable for diagnosing congenital or acquired antithrombin deficiencies which are known to be linked with an increased risk of thrombosis. Antithrombin deficiencies manifest themselves in reduced activity of the antithrombin protein. Two types of congenital antithrombin deficiencies are distinguished: in case of deficiency type I, the total quantity of existing antithrombin protein is reduced, whereas in case of deficiency type II, the protein concentration is normal, but the protein is defective in respect of its inhibitor function. Acquired antithrombin deficiency exists if less antithrombin protein is produced or more is spent than usual. This may result, for example, from liver diseases, DIC (disseminated intravascular coagulation), sepsis, acute hemolytic transfusion reaction, nephrotic syndrome or major surgical interventions. The test can also serve for monitoring the substitution therapy with antithrombin concentrates. The test kit components of Innovance Antithrombin are ready for use and therefore especially fast and easy to use. The test is based on a chromogenic measurement principle. Citrated plasma is mixed with a surplus of coagulation factor Xa. If heparin is present, part of coagulation factor Xa is bonded and deactivated by the antithrombin present in the specimen. Surplus, uninhibited coagulation factor Xa then splits a chromogenic substrate. In this process, coloring is released, the concentration of which is detected with a photometer. The higher the concentration of the produced coloring, the higher was the quantity of uninhibited coagulation factor Xa and the lower was the concentration of functionally active antithrombin originally present in the plasma specimen.
Infection: New Mode Found Of How Diseases Evolve
Researchers have discovered a new way that bacteria evolve into something that can make sick. The finding has implications for how scientists identify and assign risk to emerging diseases in the environment. The researchers found that bacteria can develop into illness-causing pathogens by rewiring regulatory DNA, the genetic material that controls disease-causing genes in a body. Previously, disease evolution was thought to occur mainly through the addition or deletion of genes. "Bacterial cells contain about 5,000 different genes, but only a fraction of them are used at any given time," Brian Coombes, lead investigator of the study, said. "The difference between being able to cause disease, or not cause disease, lies in where, when and what genes in this collection are turned on. We have discovered how bacteria evolve to turn on just the right combination of genes in order to cause disease in a host. It is similar to playing a musical instrument – you have to play the right keys in the right order to make music." With infectious diseases on the rise, the finding has implications on how new pathogens are identified in the environment. Scientists currently monitor the risk of new diseases by assessing the gene content of bacteria found in water, food and animals. "This opens up significant new challenges for us as we move forward with this idea of assigning risk to new pathogens," Coombes said. "Because now, we know it's not just gene content – it is gene content plus regulation of those genes." MEDICA.de; Source: McMaster University

Firms gloomier on outlook -By Robin Chan & Fiona Chan
The weak sentiment is affecting industries across the economic spectrum, from hotels to petroleum and manufacturing. 'Firms are becoming more realistic in their outlook,' said HSBC economist Prakriti Sofat. 'There is no escaping the fact that things are deteriorating much faster than expected.'
All clusters within the manufacturing sector are downbeat, according to a survey conducted among about 390 firms by the Economic Development Board in recent weeks.
And about 60 per cent of the 1,400 services companies surveyed by the Department of Statistics also anticipate slower business in the wake of the global economic decline.
The most downbeat industries in manufacturing are computer peripherals and petroleum while hotels in the services sector are mired in gloom with 100 per cent of those surveyed believing that there is no way but down.
All other sectors have at least a few firms which believe that things will improve by June.
A comparison with the same survey last October provides a stark illustration of just how quickly sentiment has deteriorated.
Last October, four in 10 hotels, restaurants and caterers were still optimistic. They predicted a brighter outlook for March this year, with more than 90 per cent expecting to keep the same number of jobs or hire more people by the year-end.
Now not a single hotel surveyed in the recent poll retains such optimism.
Manufacturing is almost as grim. Last October, only 18 per cent of firms were pessimistic but now that has rocketed, with 57 per cent of manufacturers expecting conditions to worsen in the next six months.
All manufacturing industries apart from biomedical manufacturing are predicting job cuts in the next few months. They believe output will fall across the board, ranging from a 14 per cent decrease in food, beverages and tobacco production to a 100 per cent drop in some electronic modules and components.
One of the few bright spots is pharmaceutical firms, with 26 per cent believing that things will look up, although more than half still think it will get worse.
Job cuts are the most visible manifestation of the mood.
Chipmaker Chartered Semiconductor Manufacturing announced yesterday that it plans to cut more than 500 jobs here after forecasting a net loss of about US$147 million (S$221 million) for the first quarter.
The manufacturing sector lost 6,200 jobs in the last three months of last year, said the Manpower Ministry yesterday.
Employment is also likely to fall for services firms, according to the survey. In almost every industry, from wholesale and retail trade to financial and business services, there are more firms predicting job cuts than those anticipating more hires. Overall, 53 per cent of services firms expect things to get worse, with banks and fund managers among the gloomiest.
The Government expects the economy to shrink by up to 5 per cent this year after growing 1.2 per cent last year. Last week, Finance Minister Tharman Shanmugaratnam unveiled a $20.5 billion 'resilience' Budget to help firms improve cashflow and preserve jobs.
Ms Sofat said: 'We are seeing things being done to cushion the blow somewhat, but it remains to be seen how much of that will actually go through. There will be more layoffs over the year, there is no escaping that fact.'

Pfizer to buy Wyeth for $68B; cut 8,000 jobs
The deal came as New York-based Pfizer set out a full house of issues: a 90 percent drop in income, a hefty charge to end an investigation, a severe cut in its dividend, a shockingly low profit forecast for 2009 and 8,000 job cuts starting immediately.
That's all on top of the colossal problem triggering this deal: the expected loss of $13 billion a year in revenue for cholesterol fighter Lipitor starting in November 2011, when it gets generic competition.
Pfizer also plans by 2011 to cut about 8,190 jobs, 10 percent of its workforce, as part of what it expects will be a staff reduction totaling 15 percent of the combined companies' workers implying a total job loss of almost 20,000.
By buying Wyeth, Pfizer will mutate from a maker of blockbuster pills to a one-stop shop for vaccines, biotech drugs, traditional pills and nonprescription products for both people and animals.
But plenty of pharmaceutical industry mergers have not lived up to their initial promise, including the deals that enabled Pfizer to leapfrog to the top of the industry buying Warner-Lambert in 2000 and, in 2003, Pharmacia Corp. Pharmacia was itself the result of the difficult marriage of Michigan's Upjohn & Sweden's Pharmacia, which took years and eventually new management to get beyond culture clash and fully integrate.
Pfizer and Warner-Lambert, likewise, had differences over Warner's focus on consumer health and Pfizer's “big corporation" image, plus “no vision as to which divisions would win out and which people would keep their jobs," recalled analyst Steve Brozak of WBB Securities.
“A lot of the turmoil that those acquisitions created hurt morale and productivity there's no doubt about that," Pfizer Chief Executive Jeff Kindler conceded during a news conference.
“We're in a much better position to bring on board the scientists and programs and projects that Wyeth has," Kindler said.
The cash-and-stock deal, one of the industry's biggest ever, is expected to close late in the third quarter or in the fourth quarter. It comes as Pfizer's 2008 fourth-quarter profit takes a brutal hit from a $2.3 billion legal settlement over allegations it marketed pain reliever Bextra and possibly other products for indications that had not been approved.
“In one single transaction, the combination with Wyeth advances every single one of (our) strategies," Kindler told reporters during a news conference.
Those goals include increasing sales in emerging markets, enhancing the ability to treat specific diseases, such as Alzheimer's, and becoming a top player in vaccines and biologic drugs, which are made from living cells.
Pfizer, also known for the impotence pill Viagra, said it will pay $50.19 per share for Madison, New Jersey-based Wyeth.
Pfizer shares closed down $1.80, or 10.3 percent, to $15.65 Monday. Wyeth shares ended 35 cents lower at $43.39.
Analysts were split on how good the deal is but saw no benefit for consumers.
“This deal doesn't bring Pfizer the cure for Lipitor" revenue losses, but it brings short- and long-term cost savings, said Erik Gordon, biomedical analyst and professor at University of Michigan's Ross School of Business. “It increases Pfizer's research capabilities in biologics, and it's good for Wyeth because Wyeth will now be able to tap into Pfizer's marketing machine."
Credit Suisse analyst Catherine Arnold wrote to investors that the deal's addition to Pfizer earnings “should be massive," and could start even before the second year.
The deal likely will close, she added, and the amount of cash and debt that Pfizer has put together makes other suitors for Wyeth unlikely
Brozak said it still doesn't solve Pfizer's long-term problem of not having enough promising drug candidates.
“The question becomes what are they going to do to fill that research gap," Brozak said.
Meanwhile, Pfizer is halving its dividend to 16 cents per share and eliminating five of 46 manufacturing sites. Those closings will cost about $6 billion before taxes, of which $1.5 billion has been incurred, Pfizer said.
Pfizer has not identified which plants it will close. Wyeth said there's been no decision on job cuts among its staff due to the acquisition.
Pfizer said the new cost-cutting program will reduce spending by about $3 billion, $1 billion of which will be reinvested in the business.
Pfizer Chief Financial Officer Frank D'Amelio said the company will put up $22.5 billion in cash and $23 billion in stock for the purchase, with $22.5 billion in debt covering the rest.
The deal is being financed by five banks: Bank of America Merrill Lynch, Barclays, Citigroup, Goldman Sachs and J.P. Morgan Chase.
The tie-up will bring about $4 billion in cost savings by the end of 2012 and should add to Pfizer's earnings per share in the second full year after closing.
Both companies' boards approved the deal but Wyeth shareholders must do so. Wyeth's CEO, Bernard Poussot, will stay on through the transition but not beyond that. The companies did not discuss the fate of other top Wyeth managers.
The deal is likely to be reviewed by the Federal Trade Commission, which typically handles pharmaceutical acquisitions. FTC spokesman Mitch Katz said the agency doesn't comment on pending transactions.
Fitch Ratings downgraded Pfizer's credit rating to 'AA' from 'AA',' and placed the company's ratings on a negative watch. Fellow ratings agencies Moody's Investors Service and Standard & Poor's are reviewing their ratings.
Acquiring Wyeth adds strengths in vaccines and biologic drugs. Together, the two companies will have 17 products with annual sales of $1 billion or more.
Shortly after announcing the Wyeth deal, Pfizer said fourth-quarter profit plunged on a charge to settle investigations into off-label marketing. The company earned $268 million, or 4 cents per share, compared with profit of $2.72 billion, or 40 cents per share, a year prior. Revenue fell 4 percent to $12.35 billion from $12.87 billion.
Excluding about $2.3 billion in legal charges, the company says profit rose to 65 cents per share.
Analysts polled by Thomson Reuters expected profit of 59 cents per share on revenue of $12.54 billion.
In 2009, Pfizer expects earnings per share between $1.85 and $1.95, below forecasts for $2.49. The outlook includes costs of 21 cents per share related to financial strategies tied to the acquisition, Pfizer said.
Wyeth said Monday its fourth-quarter profit declined 5.6 percent, to $960.4 million, or 71 cents per share, down from $1.02 billion, or 75 cents per share, in the 2007 quarter.
Excluding restructuring charges, the company earned 78 cents per share in the latest quarter. Revenue fell 7 percent to $5.35 billion, dragged down partly by unfavorable currency exchange rates.
Analysts expected Wyeth to earn 79 cents per share on revenue of $5.79 billion.
900 New Biomedical Jobs to be created in Singapore this year
DESPITE facing challenges from the slowing global economy, the biomedical sector will create 900 new jobs this year as companies go ahead with their expansion plans here.
These include firms such as Wyeth, Abbott, GSK Bio, Schering Plough and Perkin Elmer, Minister of Trade and Industry Lim Hng Kiang said in Parliament on Monday.
To date, 11 of the world’s top pharmaceutical and biotechnology companies have already invested in more than 25 manufacturing facilities in Singapore, with another seven new plants set to open in the next three years.
‘We are confident that more will come to Singapore so that they can reach out to the Asian market more effectively,’ said Mr Lim. ‘Demand for effective medicines will continue to grow because people become more affluent and people age.’
Singapore should also ‘prepare for the upturn’ by entering new niches, such as medical technology and biologics, which are complex molecules derived from cells of mammals, bacteria and yeast.
Biologics in particular is expected to grow at 13 per cent a year, compared to just 0.9 per cent for the traditional pharmaceutical market, Mr Lim said.

Biomedical sector takes steps to handle harsh financial realities - Meredith Wadman
DeCode, the pioneering Icelandic genetics and genomics company, watched its share price plunge from a 52-week high of $4.39 last December to 34 cents at closing on 13 November. This month, the company is scheduled to ask a panel convened by the NASDAQ stock exchange not to delist it now that its market capitalization has fallen below $50 million, the minimum required to trade on the tech-heavy exchange.
Although deCode is perhaps the most visible biotech struggling to survive, it is hardly alone. The Washington DC-based Biotechnology Industry Organization reported last month that nearly 100 publicly traded biotech companies have less than six months of cash remaining.
The picture is not much prettier on the pharmaceutical side, where, by the end of October, the AMEX Pharmaceutical Index, a composite of widely held, big pharmaceutical companies, had plunged more than 21% for the year.
New Jersey–based Merck was among the companies taking drastic action to trim costs. In October, as it reported a 28% drop in profits for the third quarter, it announced it would cut 7,200 jobs—more than 10% its workforce.
"We will get past this," says Mark McClellan, a former US Food and Drug Administration commissioner who now directs the Engelberg Center for Health Care Reform at the Brookings Institution, a Washington, DC think tank. But he predicts that in the long run the current economic setback, combined with the financial pressure resulting from the growth of mandatory spending programs such as Medicare and Medicaid, will mean growing scrutiny for biotech and pharmaceutical companies: "There will be increasing attention to the question: are these products truly valuable? Are they making a real difference in the health of Americans, given how much money we're spending on them?"
