Australian researchers say they have scientifically proven that stress causes sickness. The Garvan Institute in Sydney has discovered that a hormone, known as neuropeptide Y (NPY) is released into the body during times of stress. Their findings show the hormone can stop the immune system from functioning properly.

“Neuropeptide Y is one of those hormones that gets unregulated or released from neurones when stressful situations occur…it’s known for example that it regulates blood pressure and heart rates so your heart rate goes up but it hasn’t been known that it actually can affect immune cells as well,” said Professor Herbert Herzog, one of the researchers.

Herzog feels it is good to finally have proof of something people have suspected for so long.

“Now we have proven without doubt that there is a direct link and that stress can weaken the immune system and that makes you more vulnerable when you for example have a cold or flu and even in the more serious situations such as cancer can be enhanced in these situations,” said Herzog.

The Garvan Institute study centres on two key events that enable the human body to recognise foreign substances and control invaders. When our body encounters a pathogen (bacteria and viruses), the immune cells retain and interrogate suspects. Their activation is made possible by NPY. These cells then return to the lymph nodes, which are found all over the body, with information about the foreign invaders. The lymph nodes are where decisions about defence are made.

“Most of us expect to come down with a cold or other illness when we are under pressure, but until now we have mostly had circumstantial evidence for a link between the brain and the immune system,” said lead Garvan researcher, associate Professor Fabienne Mackay. “During periods of stress, nerves release a lot of NPY and it gets into the bloodstream, where it directly impacts on the cells in the immune system that look out for and destroy pathogens (bacteria and viruses) in the body.”

In the case of bacteria and viruses, TH1 cells are part of the attack team that is sent out on the ‘search and destroy’ mission. But when their job is done they need to be turned ‘off’ and the immune system reset. The same hormone, NPY, that activates the sentry cells now prompts the TH1 cells to slow down and die.

“Under normal conditions, circulating immune cells produce small amounts of NPY, which enables the immune cells on sentry duty and the TH1 immune cells to operate – it’s a yin and yang kind of situation. But too much NPY means that the TH1 attack is prevented despite the foreign invaders being identified – and this is what happens during stress,” added McKay.

The impact of stress on the body has been observed in athletes. Ph. D researcher at the University of Queensland, Luke Spence, together with the Australian Institute of Sport, studied elite and recreational athletes over five months.

They found elite athletes were more susceptible to respiratory diseases under stress.

“A lot of elite athletes put themselves through vast amounts of physical stress in their training, but also their emotional, psychological stress of feeling the pressure of Australia on their shoulders, wanting to compete and wanting to do their best,” said Spence.

It’s not just athletes who are prone to stress. Pressures at work and at home may cause emotional and mental stress that can be equally damaging. Almost a third of all work absenteeism in Australia is due to illness, costing employers over $10 billion a year.

“I think it has a huge impact for the work force and also for employers – if their employees are constantly stressed, constantly under pressure, they are more likely to get sick,” Spence said.

Further research could lead to the development of new drugs which may inhibit the action of the neuropeptide Y hormone.

Herzog warns people to minimise stress before it becomes a problem.

“Relaxation methods like yoga will help you to prevent that but there will still be people out there that are not responding to that and treatment by interfering with the system will be important,” he said. “There’s obviously some time until such a treatment will be available but this is something we will definitely work towards.”

The Garvan research will be published in the Journal of Experimental Medicine, Volume 202, No. 11.

On October 14, 2008, Canadians will be heading to the polls for the federal election. New Democratic Party incumbent Wayne Marston is standing for re-election in the riding of Hamilton East—Stoney Creek.

Marston ran in the former federal riding Hamilton East three times, in 1993 and 1997 election and 1996 by-election, losing to prominent Liberal Shelia Copps. Prior to his winning election campaign in 2006, Marston was President of the Hamilton and District Labour Council, serving for 11 years. He was also a School Board Trustee (Ward 5) for the Hamilton-Wentworth District School Board from 2000 to 2006.

Wikinews contacted Wayne, to talk about the issues facing Canadians, and what they and their party would do to address them. Wikinews is in the process of contacting every candidate, in every riding across the country, no matter their political stripe. All interviews are conducted over e-mail, and interviews are published unedited, allowing candidates to impart their full message to our readers, uninterrupted.

This riding consists of the part of the Hamilton lying north of the Niagara Escarpment and east of Ottawa Street. It was formed in 2003 from parts of the old ridings Hamilton East and Stoney Creek. Wanting to take Marston’s seat from his are Liberal Larry Di Ianni, Green David William Hart Dyke, and Conservative Frank Rukavina. A candidate from the newly formed Progressive Canadian party, Gord Hill, as well as independent Sam Cino are also running.

Indonesia has shut down four airlines and grounded five others with the potential of similar licence revocations for failing to meet safety standards.

The largest company to lose its licence is Jatayu Gelang Sejahtera. The other companies are all small airlines operating only aircraft with a passenger capacity of fewer than thirty, and are Aviasi Upataraksa, Alfa Trans Dirgantara and Prodexim. The companies that were grounded pending either improvements or licence revokation are Germania Trisila Air, Atlas Delta Setia, Survey Udara Penas, Kura-kura Aviation and SMAC, all of which also operate only aircraft with under-30 passenger capacities. They have three months to improve, or their licences will be revoked.

Jatayu had already ceased operations in August, but had intended to restart with a 150-seat Boeing 737. The licence was revoked because the state requires at least two aircraft to be commercially operated and because of the fact that it “was lacking in pilots and human resources”. Also, the age of the jetliner meant that it would require a test called a ‘C-Check’ before it could begin commercial services, at a cost of $120,000.

The action comes as the result of a number of air crashes, namely the Adam Air Flight 574 disaster in which 102 people were killed, and the Adam Air Flight 172 accident, in which a plane snapped in half during a hard landing, but managed to hold together, thus preventing any serious injuries. As a result, all 54 of Indonesia’s airlines were given a safety rating, with a level-1 rating meaning no action was needed, a level-2 rating meaning the airline needed to make some improvements, and a level-3 rating requiring that the airline be shut down unless improvements were made within three months. Most airlines received a level-2 rating, while none received the top rating. Adam Air was among the airlines to receive the level-3 rating, but was upgraded to tier 2 at the same time as the groundings.

Meanwhile, state-owned Garuda Indonesia is now the only airline to have a type-1 rating, despite the fatal crash of Garuda Indonesia Flight 200 in March. According to the Indonesian Transport Ministry’s Director General for Aviation Budi Mulyawan Suyitno, Garuda now satisfied 84 percent of civil aviation standards.

The ratings have been based on such criteria as surveillance, ramp checks, personnel, department safety, number of accidents and number of serious incidents, according to the BBC. Meanwhile, Flight Global is reporting that, according to Directorate General of Air Communications (DGAC) director of air certification office, Yurlis Hasibuan “20 criteria including whether the airline has developed [better] safety and human resources” are checked.

North America’s largest outdoor dog festival came back to Toronto last weekend for its fifth year. It ran from the 9th of June to the 10th of June at Toronto’s historical St. Lawrence Market. A Wikinews reporter was there on Sunday to report on some of the events that happened on the last day.

The “Woofstock” dog festival attracted as many as 140,000 people with their dogs. The festival had tons of accessories, sold under tents, to buy for dogs; food, toys, designer clothes, and more. About 400 vendors and exhibitors were there to promote their products, which also gave private dog companies or groups a chance to show their new products. The local SPCA and some animal rescues were under tents answering questions from visitors. While walking, all visitors could see the CN Tower and other very tall buildings.

One of the local TV stations, Citytv, was there. They hosted a live event at the show which was broadcast on TV. People came up on the stage and asked questions regarding their dogs and the host and co-host answered them.

A man, who called himself the “Chalk Master”, drew two pictures on pavement with chalk. He did it for free but donations were welcome. One was a picture of a girl’s head beside a dog’s head, and another with a wolf.

“Hello Humans. I’ve been invited here to provide your eyeball(s), with some pretty colours. I don’t get paid as I work this weekend strictly for tips… so, if you like what you see please make a DONATION. If you don’t like it simply reach into the pocket of the person next to you and give me their money. CHALK MASTER.”

A contest called “Canada’s top dog” had its own tent with a professional photographer taking pictures of dogs behind a white screen; the winning photo is to be published on the cover of “Puppy and dog basics” magazine.

Large “Gourmet” dog bones were also served from a cart and table.

Next year’s festival is expected to be bigger and better with even more attractions.

The Globe and Mail (Toronto, ON), citing sources close to both sides in the dispute, reported Wednesday that the National Hockey League and the NHLPA have agreed to a salary cap structure, arguably the most contentious issue in the continuing lockout that led to the cancellation of the 2004-05 NHL season on 16 February, 2005.

The Globe and Mail is reporting that the deal, providing the “cost certainty” that the NHL has been seeking, will consist of a floating, team-by-team salary cap and floor based on a percentage of each team’s revenue projections. What is being reported as a six-year deal has a salary cap range of $34-36 million and a salary floor of $22-24 million, both hard caps. The new deal will also reportedly include the across-the-board 24% decrease in salary offered by the NHLPA in February. A dollar-for-dollar Luxury tax will also take effect at the halfway point between the lowest salary floor and the highest salary cap (slated to be $29 million for the first year of the deal). Details about what will be done with this money have not been completely worked out, but it is thought that this money will be distributed to teams below the halfway point in such a way as to make sure they remain above the salary hard minimum.

While this is one of the most contentious issues in the labor dispute, there are several other issues that may delay the signing of a new Collective Bargaining Agreement. These include deciding how high-payroll teams will drop to the new maximum, working on new systems for salary arbitration, free agency, Olympic participation, and drug testing, and to design a complete revenue-sharing system.

Countries and organizations from around the world are sending aid and help to victims of the devastating 7.0 magnitude earthquake that struck Haiti on Tuesday, damaging many buildings. The death toll is currently unknown, but estimated to run into the tens of thousands of people.

US president Barack Obama said in a press conference that “I’ve directed my administration to launch a swift, coordinated and aggressive effort to save lives and support the recovery in Haiti.”

Obama announced that aid from the US armed forces was coming to Haiti, noting, “Several Coast Guard cutters are already there providing everything from basic services like water, to vital technical support for this massive logistical operation.”

Obama continued: “[…] today, I’m also announcing an immediate investment of $100 million to support our relief efforts. This will mean more of the life-saving equipment, food, water and medicine that will be needed. This investment will grow over the coming year as we embark on the long-term recovery from this unimaginable tragedy.”

Obama said that the US would forge partnerships with Haitian people and Haitian-Americans, along with United Nations peacekeepers. He closed by saying, “To the people of Haiti, we say clearly, and with conviction, you will not be forsaken; you will not be forgotten. In this, your hour of greatest need, America stands with you. The world stands with you.”

The UN Secretary-General, Ban Ki-moon said that $10 million is being released from the international organization’s central emergency response fund.

Meanwhile, the UN’s World Food Programme (WFP), which already has an existing operation in the country, is beginning to distribute high energy biscuits which require no preparation before eating. On top of that, the WFP is airlifting 86 metric tons of food from their emergency hub in El Salvador.

A spokesperson for the WFP said, “In a normal day the World Food Programme will be feeding one or two million people in Haiti — and now we need to do even more, because the people have lost everything.”

China is also pledging aid to the country, despite the lack of official diplomatic ties between the two countries. Haiti recognizes the Republic of China, better known as Taiwan. Nevertheless, China has sent a 60 member search and rescue team to Haiti and the Chinese Red Cross is donating one million dollars in emergency aid.

Chinese Foreign Ministry spokesperson Jiang Yu said her country expresses sympathy to the Haitian government and people. Jiang says the Chinese foreign minister has sent a telegram of condolence to his Haitian counterparts.

An 80 member team from the United Kingdom of search and rescue specialists has arrived in Haiti to help in efforts there. British Prime Minister Gordon Brown said in a joint press conference with Toaiseach of Ireland Brian Cowen that the team has arrived in the country. He also announced that the government is pledging to match the UN’s US$10 million (£6.1 million).

Brown said, “It is a tragedy beyond imagination and there is a deep sense of loss felt by the whole of the British and Irish people about the tragedy that individual families in Haiti are experiencing at the moment. We send our message of sympathy and support to the people of Haiti at this most difficult of times.”

He added, “Where men, women and children are suffering under the heaviest of burdens, that place must, for that moment, become the centre of our world’s attention, the world’s compassion and the world’s humanitarian help.”

France is also sending aid to the French-speaking country, which at one time was a colony of France known as Saint-Domingue. France is sending two planes with rescuers and aid. Civil safety authorities in France are sending a team of 130 members consisting of rescuers, trained rescue dogs, doctors and nurses along with 12,000 tons of aid and rescue supplies.

Israel is sending rescue forces in two El Al planes carrying a 121-member delegation that includes 40 doctors, five search-and-rescue teams, and an army rescue squad. The IDF medical teams are preparing to spend two weeks in Haiti.

Spain has pledged $4.3 million (€3 million) in aid money and has 150 tons of aid ready to be delivered.

South Africa is sending a team of search and rescue specialists to Haiti in response to the devastating earthquake on Tuesday. It is the first of several teams being sent by a local civic group.

The head of South Africa’s Gift of the Givers Foundation, Emtiaz Sooliman, says his group is sending up to three teams of search and rescue specialists to Haiti to help victims of the earthquake and hopefully save some lives.

“These are people who have worked with building collapses, urban search and rescue and some of them have been involved in responding to previous earthquakes so they are highly skilled,” he said.

Sooliman says a second team is to depart as soon as he can book a flight for it.

Today at about 1600 UTC/GMT, South African President Thabo Mbeki announced in a special session of parliament that he has taken action he feels is necessary, that is to “release [his deputy president], Jacob Zuma, from his responsibilities as deputy president of the republic and member of the cabinet”.

Zuma was implicated in corruption arising from his relationship with his former financial adviser, Schabir Shaik, who was convicted of corruption and fraud earlier this month. Shaik was found guilty by Durban High Court of two counts of corruption and one of fraud and was sentenced to 15 years imprisonment.

The President has called this one of his toughest decisions. Opposition leader of the Democratic Alliance immediately praised the president for holding “principle over politics”, and, while deeply saddened, former president Nelson Mandela supported Mbeki’s decision. Jacob Zuma was the favourite of the ruling African National Congress party to succeed Thabo Mbeki as president.

Following this ordeal, the government of South Africa has reaffirmed its dedication to the reduction and eventual elimination of corruption in all areas of politics.

UPDATE (July 7)

The African National Congress held a meeting of it’s National General Council over the weekend of 2-3 July. Zuma attracted a lot of favourable attention, mostly from people who wished to defeat policy initiatives that included relaxing some of the legal constraints on employers. He was reinstated as ANC deputy president and, in a first for the party, granted a salary (details not revealed). It now appears that Jacob Zuma’s political future is closely tied to that of the “left wing” of the ANC.
