DHAKA Ronald Jones II Womens Jersey , June 2 (Xinhua) -- Dhaka has denied the allegation that anti-Myanmar groups operating from its soil but expressed keenness to look into the matter if Myanmar provides an evidence or specific information, officials said Sunday.

They said Dhaka is still keen to push forward the "growing relations" and work closely with the next-door neighbor despite a soldier was killed in a firing on Bangladeshi paramilitary personnel Wednesday.

"There is no evidence of any anti-Myanmar group operating activities from Bangladesh," the country's Foreign Secretary Md Shahidul Haque told journalists Sunday.

He said, "If they have evidence or specific information they can share with us and we'll surely look into the matter."

"We want to solve all border related disputes with Myanmar through mutual discussion and more engaged manner," he said Carlton Davis Womens Jersey , adding, "We can establish a platform for security dialogue on a regular basis."

Tension between the neighbors rose at a time when Dhaka and Naypyidaw embarked on a series of diplomatic measures to enrich bilateral ties in the recent years.

In the wake of tension over the shooting on the Border Guard Bangladesh (BGB) patrol team and the subsequent disappearance of its troops, Bangladesh's Ministry of Foreign Affairs summoned the Myanmar envoy to Dhaka U Myo Myint Than at State Guesthouse Padma Saturday for the second time since Wednesday to protest the firing.

Myanmar's Border Guard Police (BGP) reportedly shot at a BGB patrol team near the border at Painchhari area of Bandarban, some 316 km away of capital Dhaka, and allegedly detained injured BGB's Nayek Mizanur Rahman in Bangladeshi territory.

Bangladesh and Myanmar forces traded gunfire along their border on Friday for hours.

Sources said situation started to ease in Bangladesh side after Myanmar's border force Saturday evening handed over the body of a Bangladesghi paramilitary troop killed in Wednesday's firing.

Bangladesh's State Minister for Home Asaduzzaman Khan Kamal Sunday called the incident a "misunderstanding" and expressed the hope that Myanmar would withdraw its troops from the border as the tension had eased.

Bangladeshi Foreign Minister Abul Hassan Mahmood Ali also hoped that the two countries will work together to end the impasse peacefully.

He said the Bangladeshi government in the spirit of good neighborly relations has strongly encouraged the visit of the BGB chief and his delegation to Myanmar from June 9 to 14.

"We're keenly interested to forward regular activities to further strengthen bilateral relations with Myanmar Vita Vea Womens Jersey ," he told journalists Sunday.


SAN FRANCISCO, March 17 (Xinhua) -- In what could lead to contraceptives that work in both men and women, researchers at University of California, Berkeley, have identified a protein receptor on the surface of sperms that responds to the female sex hormone progesterone.

Describing the receptor as a switch Authentic Mike Alstott Jersey , or a trigger, the researchers said it is the key to the ""power kick"" needed by a sperm to penetrate and fertilize a human egg.

""If the receptor protein doesn't recognize progesterone, you would be infertile,"" said Melissa Miller, a postdoctoral fellow at both UC Berkeley and University of California Authentic Noah Spence Jersey , San Francisco, and the first author of a paper published on Thursday in the ""Fast Release"" issue of the journal Science.

Progesterone is released by the egg or oocyte, the ultimate goal toward which sperm swim. When the sperm gets close to the egg, the hormone activates the receptor and triggers a cascade of changes that make the tail snap like a whip, powering the sperm into and hopefully through the cells protecting the egg.

The receptor ""gives us an understanding of another pathway that is involved in human sperm activity Authentic Kendell Beckwith Jersey ,"" Miller said, adding that ""what's really cool is that we have an actual target for unisex contraceptive development.""

""If you can stop progesterone from inducing a power stroke, sperm are not going to be able to reach or penetrate the oocyte,"" she explained.

The new discovery has also uncovered a possible source of male infertility, as sperm may be to blame in half of all cases of infertile couples Authentic Ali Marpet Jersey , while doctors currently are unable to determine the cause of nearly 80 percent of all cases of male infertility.

In their lab work, techniques that Polina Lishko, a UC Berkeley assistant professor of molecular and cell biology, and her colleague Yuriy Kirichok developed over the past five years at UCSF and UC Berkeley were used, allowing them to stick electrodes on a sperm's tail and record its reactions to hormones.

That led to their discovery that a large receptor on sperm tails -- a calcium channel dubbed CatSper -- is activated by progesterone from the egg. Progesterone unlocks the channel gate Authentic Donovan Smith Jersey , letting electrically charged calcium atoms flood into the cell, leading to a biochemical cascade that readies the sperm cell for its last-ditch effort to fertilize the oocyte.

Miller and Lishko, senior author of the paper, suspected that progesterone was not acting directly on the calcium channel, but on some other receptor that activated the calcium channel.

The team did confirm that progesterone actually binds to a previously mysterious enzyme called ABHD2 Authentic Vernon Hargreaves III Jersey , which is found at high levels in sperm. Once progesterone binds to the enzyme, which sits on the surface of the sperm, it removes a lipid (2AG) that has been inhibiting the calcium channel. Released of inhibition, CatSper opens the gate to calcium ions and eventual sperm activation.

The inhibitor of CatSper is probably there for a good reason: to prevent sperm from prematurely sprinting toward the egg and using up their limited supply of energy, Miller said.
