WASHINGTON Comprar Hombre Nike Air Max 2018 Elite Azul Blancas , Aug. 16 (Xinhua) -- U.S. researchers said Wednesday that they have developed a new test that identified more than half of 138 people with relatively early-stage colorectal, breast, lung and ovarian cancers by detecting tiny amounts of DNA circulating in the blood that originate from tumors.


"This study shows that identifying cancer early using DNA changes in the blood is feasible and that our high accuracy sequencing method is a promising approach to achieve this goal," said Victor Velculescu, professor of oncology at the Johns Hopkins Kimmel Cancer Center Comprar Hombre Nike Air Vapormax 2018 Negras , whose study was published in the U.S. journal Science Translational Medicine.


Blood tests for cancer are a growing part of clinical oncology, but they remain in the early stages of development.


To find small bits of cancer-derived DNA in the blood of cancer patients, scientists have frequently relied on DNA alterations found in patients' biopsied tumor samples as guideposts for the genetic mistakes they should be looking for among the masses of DNA circulating in those patients' blood samples.


The challenge is that the test should distinguish between DNA shed from tumors and other altered DNA that can be mistaken for cancer biomarkers.


Most of the time, the blood-derived mutations are not cancer-initiating, and "false positive" results often lead to unnecessary overtesting and overtreatments.


To develop the new test Comprar Hombre Nike Air Vapormax 2018 Negras Rojos , Velculescu and colleagues obtained blood samples from 200 patients with breast, lung, ovarian and colorectal cancer.


The scientists' blood test screened the patients' blood samples for mutations within 58 genes widely linked to various cancers.


Overall, the scientists were able to detect 86 of 138 stage I and II cancers.


The team also performed independent genomic sequencing on available tumors removed from 100 of the patients and found that 82 had mutations in their tumors that correlated with the genetic alterations found in the blood.


They also tested blood samples of 44 healthy individuals and did not find any cancer-derived mutations.


Despite these initial promising results for early detection, the blood test needs to be validated in studies of much larger numbers of people Comprar Hombre Nike Air Vapormax 2018 Granates Rojos Negras , said the scientists.


The new blood test is based on deep sequencing, which reads each chemical code in DNA 30,000 times. It's very costly but Velculescu stressed that sequencing technology is becoming cheaper.


He predicted that people that could benefit most from such a DNA-based blood test include those at high risk for cancer including smokers -- for whom standard computed tomography scans for identifying lung cancer often lead to false positives -- and women with hereditary mutations for breast and ovarian cancer within BRCA1 and BRCA2 genes.



BEIJING, Dec. 20 (Xinhua) -- Xi Jinping Thought on Socialist Economy with Chinese Characteristics for a New Era has taken shape, according to a statement released after the Central Economic Work Conference concluded on Wednesday.


The thought is the "theoretical crystallization" of the past five years of practice in pushing forward China's economic development Comprar Nike Air Vapormax 2018 Mujer Negras Rosa , and the "latest fruit" of socialist political economy with Chinese characteristics, the statement said.


The three-day conference was attended by President Xi, who is also general secretary of the Communist Party of China (CPC) Central Committee and chairman of the Central Military Commission.


The annual meeting, which set the tone for China's economic policies in 2018, also described the thought as the "extremely precious spiritual wealth" of the CPC and the country. It must be adhered to for a long time and developed continuously.


According to the statement Comprar Nike Air Vapormax 2018 Mujer Morado , the thought is mainly based on the new development philosophy, which was put forward by Xi in 2015 and features innovative, coordinated, green, open and shared development.


During the conference Comprar Mujer Nike Air Vapormax 2018 Grises Rosa , the most important annual meeting on economic work in the country, Chinese leaders reviewed the country's economic performance over the past five years and mapped out plans for 2018.


This year's conference came after the CPC's twice-a-decade national congress in October, during which Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era was unveiled and listed as a part of the guiding ideology for the CPC in its amended Constitution.


"High-quality development" is a key phrase of the conference. China's economy has transitioned from a phase of rapid growth to a stage of high-quality development, said the statement.


"High-quality development is the fundamental requirement for determining the development path, making economic policies Comprar Mujer Nike Air Vapormax 2018 Rosa , and conducting macroeconomic regulation at present and in the period to come," it said.


China will further supply-side structural reform and adopt a prudent and neutral monetary policy and a proactive fiscal policy, it said.


The leaders have also defined "preventing and defusing major risks, targeted poverty alleviation and pollution control" as the "three tough battles" for the next three years, according to the statement.





RIO DE JANEIRO, August 16 (Xinhua) -- World Cup runners-up Serbia swept Russia 3-0 (25-9, 25-22, 25-21) in the Olympic women's volleyball tournament on Tuesday evening to enter an Olympic semi-final for the first time in history.


Tijana Boskovic had 15 kills and five aces to lead Serbia with 20 points with Milena Rasic and Brankica Mihajlovic adding 16 and 14 respectively.


Serbia converted on 42 of their 87 attacking attempts while Russia managed 29 kills in 77 tries. Serbia produced a total of 12 aces, compared to two for Russia.


Tatiana Kosheleva led Russia with 17 points.


Serbia will play the United States, 3-0 winners over Japan in the quarter-finals earlier on Tuesday, in Thursday's.
