Stroke survivors do advance floor yoga postures focused on hip and ankle range of motion and strength 

1) Yoga May Help Stroke Survivors Improve Balance:

In a small pilot study, researchers tested the potential benefits of yoga among chronic stroke survivors -- those whose stroke occurred more than six months earlier.

"For people with chronic stroke, something like yoga in a group environment is cost effective and appears to improve motor function and balance," said Arlene Schmid, Ph.D., O.T.R., lead researcher and a rehabilitation research scientist at Roudebush Veterans Administration-Medical Center and Indiana University, Department of Occupational Therapy in Indianapolis, Ind.

The study's 47 participants, about three-quarters of them male veterans, were divided into three groups: twice-weekly group yoga for eight weeks; a "yoga-plus" group, which met twice weekly and had a relaxation recording to use at least three times a week; and a usual medical care group that did no rehabilitation.

The yoga classes, taught by a registered yoga therapist, included modified yoga postures, relaxation, and meditation. Classes grew more challenging each week.

Compared with patients in the usual-care group, those who completed yoga or yoga-plus significantly improved their balance.

Modeling of New Enzymes Helps Develop Therapies for Cocaine Abuse 

2) Modeling of New Enzymes Helps Develop Therapies for Cocaine Abuse:

Researchers from the University of Kentucky have designed and discovered a series of highly efficient enzymes that effectively metabolize cocaine. These high-activity cocaine-metabolizing enzymes could potentially prevent cocaine from producing physiological effects, and could aid in the treatment of drug dependency.

The results of this study by Chang-Guo Zhan et al are published in the journal PLOS Computational Biology.

The effectiveness of the enzymes' work was evaluated through modeling cocaine pharmacokinetics, the study of the body's action on administered external substances, such as cocaine, when the enzyme exists in the body. As there is no FDA-approved anti-cocaine medication, the medical and social consequences of cocaine abuse have made the development of anti-cocaine medication a high priority.

Administration of an enzyme to enhance cocaine metabolism has been recognized as a promising treatment strategy for overdose and abuse. A remarkable feature of the enzyme-based therapeutic approach is that one enzyme molecule can degrade many thousands of drug molecules per minute.

The first bio-inspired microrobot capable of not just walking on water like the water strider – but continuously jumping up and down like a real water strider – now is a reality

3) First Robot That Mimics the Water Striders' Jumping Abilities:

 The first bio-inspired microrobot capable of not just walking on water like the water strider -- but continuously jumping up and down like a real water strider -- now is a reality. Scientists reported development of the agile microrobot, which could use its jumping ability to avoid obstacles on reconnaissance or other missions.

Qinmin Pan and colleagues explain that scientists have reported a number of advances toward tiny robots that can walk on water. Such robots could skim across lakes and other bodies of water to monitor water quality or act as tiny spies. However, even the most advanced designs -- including one from Pan's team last year -- can only walk on water. Pan notes that real water striders actually leap. Making a jumping robot is difficult because the downward force needed to propel it into the air usually pushes the legs through the water's surface. Pan's group looked for novel mechanisms and materials to build a true water-striding robot.

Using porous, super water-repellant nickel foam to fabricate the three supporting and two jumping legs, the group made a robot that could leap more than 5.5 inches, despite weighing as much as 1,100 water striders. In experiments, the robot could jump nearly 14 inches forward -- more than twice its own length -- leaving the water at about 3.6 miles per hour. The authors report that the ability to leap will make the bio-inspired microrobot more agile and better able to avoid obstacles it encounters on the water's surface.

4) Eye-Writing Technology: Writing in Cursive With Your Eyes Only:

"Contrary to the current belief, we show that one can gain complete, voluntary control over smooth pursuit eye movements," says Jean Lorenceau of Université Pierre et Marie Curie-Paris. "The discovery also provides a tool to use smooth pursuit eye movements as a pencil to draw, write, or generate a signature."

The advance could be of great benefit for people deprived of limb movements, such as those with Lou Gehrig's disease (also known as ALS), the researchers say. It might also help to improve eye movement control in people with certain conditions such as dyslexia or ADHD and/or for experts, such as athletes or surgeons, whose activities strongly rely on eye movements.

In everyday life, smooth pursuit eye movement is used to track moving targets, Lorenceau explains. While people do have the ability to move their eyes in exquisitely sophisticated ways -- and in fact our eyes never cease to move -- it is normally impossible to control those movements smoothly in any direction.

5) Genetic Cause of Most Lethal Brain Tumor Pinpointed: May Lead to New Treatment:

Researchers at Columbia University Medical Center (CUMC) have discovered that some cases of glioblastoma, the most common and aggressive form of primary brain cancer, are caused by the fusion of two adjacent genes. The study also found that drugs that target the protein produced by this genetic aberration can dramatically slow the growth of glioblastomas in mice.

The findings were published July 26 in the online edition of the journal Science.

"Our findings are doubly important," said study leader Antonio Iavarone, MD, professor of pathology and neurology at CUMC, and a member of the Herbert Irving Comprehensive Cancer Center (HICCC) at NewYork-Presbyterian Hospital/Columbia University Medical Center. "From a clinical perspective, we have identified a druggable target for a brain cancer with a particularly dismal outcome. From a basic research perspective, we have found the first example of a tumor-initiating mutation that directly affects how cells divide, causing chromosomal instability. This discovery has implications for the understanding of glioblastoma as well as others types of solid tumors."

The fusion of these two genes was observed in just three percent of tumors studied, so any therapy based on this particular genetic aberration would apply to only a small subset of glioblastoma patients. "It's unlikely that we will find a gene fusion responsible for most glioblastomas. But we may be able to discover a number of other gene fusions, each accounting for a small percentage of tumors, and each with its own specific therapy," said co-senior author Anna Lasorella, MD, associate professor of pathology and pediatrics at CUMC and a member of the Columbia Stem Cell Initiative and the HICCC.

Glioblastomas are tumors that arise from astrocytes, star-shaped cells that make up the brain's supportive tissue. Since astrocytes reproduce quickly and are supported by a large network of blood vessels, glioblastomas are usually highly malignant. It is estimated that these tumors affect about 10,000 people in the United States each year. Glioblastoma is typically treated with surgery, followed by radiation and chemotherapy. However, the disease is invariably fatal, with a median survival of about 14 months after diagnosis, even with aggressive therapy. Glioblastomas took the lives of Senator Edward Kennedy in 2009 and New York Mets all-star catcher Gary Carter in 2012.

Several common single-gene alterations have been observed in glioblastoma. "However, therapies targeting these alterations have not improved clinical outcomes, most likely because they have systematically failed to eradicate the proteins to which the tumor is 'addicted,'" said Dr. Iavarone.

1) 3rd ODI: Indians get ready for another tough contest:

The Indians would like to ensure that the previous match's batting debacle is not repeated.

The Indian cricket team will aim to pick up the pieces after a disastrous performance in the last match and get their campaign back on track when they take on hosts Sri Lanka in the third ODI to be held on Saturday.

After a couple of contrasting performances in the two matches at Hambantota where Men in Blue first won comfortably by 21 runs before being soundly thrashed by nine wickets, the action moves to the familiar territory of Premadasa Stadium here.

Skipper Mahendra Singh Dhoni is not very fond of tinkering with his playing XIs but he now seriously needs to think as to how many more chances does Rohit Sharma deserve in order to prove that he is a regular match-winner like Virat Kohli or even fairly consistent on sub-continental tracks like Suresh Raina.

The Mumbai batsman had scores of 1 and 0 in the first two matches where he was out in identical fashion chasing a delivery away from his body to be played on.

A moment of pride; a moment of ecstasy; a moment of cheer... That's what every Indian felt when they saw Bollywood megastar Amitabh Bachchan held the prestigious Olympic torch in his hand...

On Thursday, the veteran superstar carried the torch through Southwark in south London, much to the excitement of the onlookers, especially for the Indians there and movie buffs. There was loud cheers when Big B passed by holding the torch, wearing a white tracksuit which had 063 printed on it.

 "It is not a flame you hold, it is the pride of 1.25 billion people of India," saying thus, the superstar aptly summarised how he felt at the moment.

The 69-yr old celebrity was invited for the event by London Games Chairman Sebastian Coe. Recalling the proud moment, Big B wrote in his micro-blogging site about the exciting "indescribable" experience.

Tweeted the megastar, "Faced many situations where enormity of crowd and its response was unbelievable. But today with Olympic torch it was indescribable."

Amitabh Bachchan later in his blog wrote that this has been an incredible honour, humbling and so full of pride and emotion.

"A moment to be hopefully remembered by the grandchildren," added the iconic actor, who was among the 173 torchbearers on Thursday.

1) Pranab Mukherjee Sworn In as 13th President of India:

Pranab Mukherjee Sworn In as 13th President of India

Pranab Mukherjee, who has had an active political career spanning five decades, today became the 13th President of India pledging to protect the Constitution and rise above personal or partisan interests.

The 76-year-old leader, who is the first leader from Bengal to become President, was administered the oath of office to "preserve, protect and defend the constitution and law" by Chief Justice of India Sarosh Homi Kapadia at an impressive ceremony in the historic Central Hall of Parliament.

The veteran leader, who had played significant roles in government, party and Parliament in his long political career, took the oath in English in the name of God to a thunderous applause and thumping of desks by those in the packed Central Hall.

Vice President Hamid Ansari, Speaker Meira Kumar, Prime Minister Manmohan Singh and outgoing President Pratibha Patil, Cabinet Ministers, leaders of opposition, UPA Chairperson Sonia Gandhi, Governors, Chief Ministers, MPs and diplomats were present in the ceremony.

West Bengal Chief Minister Mamata Banerjee, who announced her party's support to Mukherjee at the last moment, and Bihar Chief Minister Nitish Kumar, whose party JD(U) broke ranks with NDA, also attended the function.

Shortly after he assumed office, it was announced that Omita Paul, his long-time aide, was appointed as Secretary to the President.

In his brief acceptance address, he said the principal responsibility of this office is to function as the guardian of the Constitution.

"I will strive to preserve, protect and defend our Constitution not just in word but in spirit," Mukherjee said in his speech that was punctuated by repeated thumping of desks and applause. "I am deeply moved by the high honour you have accorded to me. Such honour exalts the occupant of this office, even as it demands that he rises above personal or partisan interests in the service of the national good," he said.

"There is no greater reward for a public servant than to be elected the first citizen of our republic," Mukherjee said.

The veteran leader reminded the gathering whose majority included top leaders of political parties, MPs, chief ministers and governors that "We are all, across the divide of party and region, partners at the altar of our motherland".

He said word poverty should be eliminated from the dictionary of modern India.

"There is no humiliation more abusive than hunger. Trickle-down theories do not address the legitimate aspirations of the poor. We must lift those at the bottom so that poverty is erased from the dictionary of modern India," Mukherjee said.

He also said that corruption is an evil and "we cannot allow our progressed to be hijacked by the greed of a few".

2) Assam violence continues, CM blames Centre :

 Assam Chief Minister Tarun Gogoi defended his government against allegations that it was slow to react to the rioting, and failed to anticipate the violence

While the death toll in the ethnic violence in Assam went up to 44, the blame game within the political arena was on. Assam Chief Minister Tarun Gogoi defended his government against allegations that it was slow to react to the rioting, and failed to anticipate the violence. He said a reduction in Central forces has made his task tougher. Gogoi also ruled out resignation, saying that his resignation over the issue was not going to help matters.

Assam-violence

"If they had the intelligence reports, why did they not act on their own then?" Gogoi asked. He further said, "It is my responsibility to get the normalcy back in the area. Had there been full forces there, the situation could have been controlled, I agree. I did not have sufficient forces. I requested the Centre but they had requirements across the country... So I cannot do anything there... It takes time to make movements..."

Gogoi did not spare the Opposition either, saying that the violence flared up in Assam because of the NDA regime. "This situation has flared up because of the NDA regime. They played the politics. I know Advaniji. They are responsible and they keep accusing us. It is not me who is playing votebank politics. I do not need a single vote of the illegal migrants," he said.

Assam-violence

"Media keeps asking me if I am resigning. Will my resigning not create chaos?" he asked, adding, "Like that, administration officers will say they are going to resign. Then security officers will also say they want to resign... This cannot go on... That is not the way," he added.

Assam-violence

In a strong signal to the three-time Chief Minister, the Congress has set up a 10-member coordination committee for the state. Some Congress MPs like Rehman Khan had openly criticised Gogoi, seeking his replacement.

This came even as Congress General Secretary Digvijaya Singh had defended the Assam Chief Minister saying his performance should not be judged by one incident.

The violence, that entered the sixth day on Friday, has left over 2 lakh people homeless in 400 villages. The people were taken to relief camps. Gogoi had visited the relief camps in Kokrajhar on Thursday

Russia and China yesterday blocked a crucial UN Security Council resolution on Syria while events on the ground raced ahead of the grinding diplomacy as the rebels appeared to be nearing a turning point in the conflict, announcing key strategic advances.

The United States envoy to the UN, Susan Rice, levelled a scathing statement towards Russia and China after those nations vetoed a draft Security Council resolution that called for sanctions if the Syrian regime does not make an effort to end violence within 10 days. The draft also linked compliance with the terms of the UN-Arab League envoy Kofi Annan's peace plan to Chapter Seven of the UN charter, opening up the possibility of military intervention.
