KAMPALA, Aug. 17 (Xinhua) -- Uganda's Steven Kiprotich is ready to defend his Olympic marathon gold medal when the final takes place on Aug. 21 in Rio de Janeiro, Brazil.

The 2012 Olympics star told Xinhua before departure for Brazil that he is well prepared for the challenge.

"I know the Ethiopians and Kenyans have been working hard and running good times, but I am very prepared for this," Kiprotich said.

He said he has been running in many top international events and therefore he is ready to put a good show in Rio.

"I have trained well and having two other team members in the race will be of added advantage in Rio on Aug. 21," he said.

Kiprotich, Jackson Kiprop and Solomon Munyo Mutai who are Uganda's marathon team were flagged off to Brazil on Monday.

Omara Apita, the Commissioner in-charge of Physical Education said they are confident the team will put-up a good show in Brazil and win some medals.

Uganda's athletes who have already bowed out of the on-going Olympic Games in Brazil include; Kennedy Katende, Ronald Serugo (Boxing), Jamila Lunkuse, Joshua Ekirikubinza (Swimming) and athletes Juliet Chekwel, Adero Nyakisi, Timothy Toroitich, Mose Kurong and Joshus Kiprui Cheptegei.

BEIJING ecco jared modern shoes clearance , March 11 (Xinhua) -- Taiwan politician Vincent Siew, honorary chairman of the Taiwan-based Cross-Straits Common Market Foundation ecco holton shoes clearance , will attend the Boao Forum for Asia Annual Conference 2015, a Chinese mainland spokeswoman said on Wednesday.

The Boao conference will be held in south China's Hainan Province at the end of March ecco track shoes clearance , said Fan Liqing of the State Council Taiwan Affairs Office at a press conference.

In addition, Fan said the mainland has maintained communication with Taiwan's mainland affairs committee on fixing a date for a planned visit by Zhang Zhijun ecco irving shoes clearance , head of the State Council Taiwan Affairs Office, to Taiwan and a meeting with the committee's new chief ecco hybrid shoes clearance , Andrew Hsia.

Zhang was originally scheduled to visit Kinmen on Feb. 7-8 and meet with Wang Yu-chi, who was Taiwan's mainland affairs chief until his resignation on Feb. 16. The visit has been delayed ecco howell shoes clearance , as both the mainland and Taiwan must focus on the aftermath of the plane crash in Taipei on Feb. 4.

"Exchanging visits and meetings between cross-Strait affairs chiefs is an important part of the regular communication mechanism between the State Council Taiwan Affairs Office and Taiwan's mainland affairs committee," Fan said.

SAN FRANCISCO, July 24 (Xinhua) -- A comparison of the gut microbiomes of humans, chimps, bonobos and gorillas shows that the evolution of two of the major families of bacteria in these apes' guts exactly parallels the evolution of their hosts.

Findings from the study, by an international team of researchers and published in the latest issue of the journal Science, may help calm some of the anxiety today about the bacteria in our gut being under constant assault by antibiotics, stress and bad diets.

This shows that the microbes in our guts are determined in part by our evolutionary history, not just external factors like diet, medicine and geography. Obesity, cancer and some inflammatory diseases have been linked to imbalances in the mix of microbes in our stomach and intestines.

"We are showing that some human gut bacteria are the direct descendents of gut bacteria that lived within our common ancestors with apes," said lead researcher Andrew Moeller, of Museum of Vertebrate Zoology at University of California, Berkeley. "It shows there has been an unbroken line of inheritance or transfer from one generation to another for millions of years, since the dawn of African apes."

The importance of the human microbiome has become evident over the past decade as scientists have sequenced the microbial populations from healthy and unhealthy people, from newborns to seniors, and of peoples around the world. There are about as many microbial cells in our body as our own cells, and they appear to be transmitted from mother to child during birth and continually altered by the home environment, type of diet, medications and even the family pet.

Gut bacteria, in particular, guide the early development of our intestines, train our immune systems to fight pathogens and may even affect our moods and behavior. "We know that gut bacteria are really integrated with our biology, and this research gives us a framework for investigating how that has come to be," Moeller said.

Moeller and his colleagues obtained feces from 24 gorillas living in Cameroon, 47 chimpanzees from Gombe National Park in Tanzania, 24 wild bonobos from the Democratic Republic of the Congo and 16 people from Connecticut, the United States, then isolated bacterial DNA from these samples, amplified the DNA of the gyrase B genes present and catalogued the variations within three major bacterial families to create a microbiome family tree for three families of bacteria - Bacteroidaceae, Bifidobacteriaceae and Lachnospiraceae - that together comprise about 20 percent of all the microbes in the human gut.

Only bacteria in the Bacteroidaceae and Bifidobacteriaceae families showed cospeciation with their ape hosts, with gut microbial diversity lowest in humans and highest in gorillas.

"Once we calibrated the molecular clock, we were able to date the split of human and chimp bacteria at around 5.3 million years ago, and the human-gorilla gut bacteria split at around 15.6 million years ago, which are roughly in line with what we know from fossil and genomic data of the hosts," Moeller said. "It is one more line of evidence that gut bacteria have cospeciated with humans."

"In a way, host speciation is like continental drift: When two continents drift apart, whole biotas begin to diverge," he was quoted as saying in a release from UC Berkeley. "Here, as the hosts are splitting, a good chunk of their.
