|MELBOURNE http://www.vikingsrookiestore.com/Vikings-Xavier-Rhodes-Jersey/ , March 6 (Xinhua) -- India survived a major batting scare in the ICC World Cup to sneak over the line against the West Indies with a slender four-wicket victory in Western Australia on Friday.
Needing just 183 to win after a top-order collapse from the West Indies, India nearly let a golden opportunity slip when they fell to 6134 in the 30th over.
But, as he has on countless occasions before, captain MS Dhoni held his nerve and scored an unbeaten 45 from 56 deliveries, joining in a 51-run stand with Ravichandran Ashwin to lead India to a crucial, if unconvincing win.
Having won the toss and elected to bat first, the West Indies were the victims of their own demise in the early stages of their innings.
After Mohammed Shami snared the wicket of Dwayne Smith on 6 http://www.vikingsrookiestore.com/Vikings-Will-Sutton-Jersey/ , Marlon Samuels featured in some suicidal running between the wickets to depart for 2, while a Chris Gayle brain fade saw the opener dismissed on 21.
It was a disappointing start and one that left the West Indies reeling at 435 just nine overs into their innings. But it would soon get worse.
Shami re-entered the attack and claimed his third, while both Umesh Yadav and Ravindra Jadeja joined him as multiple wicket-takers as their opposition's batting lineup verged on total capitulation.
However, young captain Jason Holder again stood tall in a crisis. Combining in 39- and 51-run partnerships down the order with Darren Sammy and Jerome Taylor respectively, he steered the West Indies to a competitive total.
While Sammy, who made 26 from 55 deliveries, and Taylor http://www.vikingsrookiestore.com/Vikings-Tramaine-Brock-Jersey/ , 11 from 18, held firm at one end, Holder bludgeoned India's attack at the other. He carted four boundaries and three over the fence on his way to 57 from 64 balls.
Having never made an ODI half-century before the tournament, Holder now has two in two games, as the West Indies finished on 182 before their captain was eventually the last man out.
In reply, India's run chase never looked convincing. Similar to the West Indies, the batting side got off to a slow start http://www.vikingsrookiestore.com/Vikings-Trae-Waynes-Jersey/ , with Taylor claiming two wickets in his first four overs.
Virat Kohli appeared as though he had stabilized matters, hitting five boundaries and quickly moving to 33, but Andrew Russell secured the prize wicket of India's Test captain as nerves swept through the camp of the reigning champions.
Consistent dismissals were hampering their innings, with Ajinkya Rahane, Suresh Raina and Jadeja all making starts, before falling at crucial times.
But, coming in at 478 http://www.vikingsrookiestore.com/Vikings-Tom-Johnson-Jersey/ , Dhoni would be the cool head that India desperately required. In a low-scoring match, his knock of 45 not out proved the decisive factor in India's victory.
Alongside Ashwin, who was also not out on 16, the pair combined in an unbroken 51-run partnership for the seventh wicket to guide India to their eighth straight ICC World Cup win, dating back to March 2011.
WASHINGTON, Aug. 11 (Xinhua) -- U.S. researchers said Monday they have created a three-dimensional brain-like tissue that functions like and has structural features similar to tissue in the rat brain and that can survive in the lab for more than two months.
The brain-like tissue, described in the U.S. journal Proceedings of the National Academy of Sciences http://www.vikingsrookiestore.com/Vikings-Terence-Newman-Jersey/ , may offer new options for studying brain function, disease and trauma, and treatment.
The key to generating the tissue was the creation of a novel composite structure that consists of two biomaterials with different physical properties: a spongy scaffold made out of silk protein and a softer, collagen-based gel, researchers at the Tufts University said.
They first cut the spongy scaffold into a donut shape and populated it with rat neurons. Then, the researchers filled the middle of the donut with the collagen-based gel, which subsequently permeated the scaffold to encourage neuron growth.
In just a few days http://www.vikingsrookiestore.com/Vikings-Teddy-Bridgewater-Jersey/ , the neurons clustered within the pores of the scaffold, forming long-lasting networks in the gels that resembled the complex circuitry of the brain in the rat.
"With the system we have, you can essentially track the tissue response to traumatic brain injury in real time," said Professor David Kaplan of the Tufts University who led the research efforts to develop the tissue.
"Most importantly, you can also start to track repair and what happens over longer periods of time."
The researchers were able to use the tissue model to examine multiple post-injury effects, including cellular damage, electrophysiological activity and neurochemical changes.
For example http://www.vikingsrookiestore.com/Vikings-Stefon-Diggs-Jersey/ , when a weight was dropped on the model tissue to simulate a traumatic brain injury, the tissue released high levels of the chemical glutamate, a neurotransmitter known to be emitted by cells following brain damage, the researchers said.
The tissue also showed transient electrical hyperactivity consistent with post-trauma responses observed in vivo, they said.
Kaplan emphasized the importance of the brain-like tissue's longevity for studying other brain disorders.
"The fact that we can maintain this tissue for months in the lab means we can start to look at neurological diseases in ways that you can't otherwise because you need long timeframes to study some of the key brain diseases," he said.
Previously, scientists have attempted to grow neurons in 3D gel environments http://www.vikingsrookiestore.com/Vikings-Sharrif-Floyd-Jersey/ , yet these gel-based tissue models don't live long and fail to yield robust, tissue-level function.
People are always looking for the best value they can get for the money they spend. This means you have to take the time to learn as much as you can about the choices you can turn to and make up your mind at the end. The more time you are willing to invest so you can learn more about your choices, the easier it will be to find what you had in mind.
For instance, if you yearn for the company of a sexy lady and you are willing to pay for.
