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.

An Oklahoma police officer is on paid administrative leave, following an altercation with ambulance personnel while they were transporting a patient to the hospital. Trooper Daniel Martin, a member of the Oklahoma Highway Patrol (OHP), was caught on video by his police vehicle’s dashboard-camera in a physical struggle with paramedic Maurice White, Jr. after Martin pulled the ambulance over. Martin had previously passed the ambulance while en route to another call, but came back and pulled over the ambulance. The incident occurred on May 24, and footage from the police dash-cam was released following a tort claim filed by paramedic White.

It has also been suggested that the previous call had in-fact been to pick up his wife from a police station who was then present in the car during the incident between Martin and the ambulance.

Footage by the OHP released Friday shows the ambulance personnel repeatedly informing Trooper Martin that they have a patient in the back of the ambulance that they are in the midst of transporting to the hospital. Martin yells at the ambulance driver for making what he claims was an obscene gesture – the ambulance driver asserts he raised both hands signalling confusion at the police officer’s actions. Trooper Martin can be heard telling the ambulance driver “I’m going to give you a ticket for failure to yield, and when I go by you saying ‘What’s going on?’ you don’t need to give me no hand gestures now, I ain’t going to put up with that [expletive], do you understand me?”

The video from the police dash-cam is eight minutes long, and paramedic White can be seen twice being pushed up against his ambulance by Trooper Martin. In one instance, Martin shoves White up against the ambulance while gripping his neck tightly with his other hand. In a written statement, paramedic White described the hold placed on him by the Trooper, stating “he engaged my trachea in a claw-like grip digging his nail into my neck while partially shutting off my air supply.”

The sister of the patient in the ambulance, Clara Harper, was following the ambulance and witnessed the incident. Harper later viewed the footage from the police dash-cam, and she stated to Tulsa World paramedic White “never once became aggressive to that trooper.” She asserted that “He did nothing wrong.” After the ambulance was allowed to continue transporting the patient to the hospital, Harper got into the ambulance to be with her sister. “She was scared, and I was trying to calm her down and telling her everything was going to be all right,” said Harper.

Paramedic White was interviewed by KOKI-TV, and recounted his thoughts as the incident was taking place. He stated his main concern was for his ambulance patient: “It was surrealistic because I’ve never had such an experience. My biggest concern was for the patient. If there’s any nightmare from this, it’s because of what that mother, that patient, had to go through.” White’s attorney told KOKI-TV that if White deemed the arrest to be unlawful, he had the right to resist it. White is a paramedic for Creek Nation Emergency Medical Services in Oklahoma. He told FOX News he was surprised at the actions of the police trooper. “He’s taken an oath, just as I have, to protect and serve. I could not believe that this was happening,” said White.

The Oklahoma Department of Public Safety decided to release the police dash-cam video publicly after amateur video of the incident was posted to the video-sharing website YouTube. Captain Chris West, spokesman for the OHP, explained why the video was not released earlier. “We’ve been well aware of the fact that this incident has drawn enormous attention, but made the decision to protect the integrity of the investigation, any and all relevant evidence, as well as the rights of the department employees,” said West. Prior to the release of the dash-cam video, a relative of the patient had posted video of the incident to YouTube. The son of the ambulance patient can be seen in a video stating to the camera “Highway patrolman pulled over my mom’s ambulance because he’s mad we didn’t pull over, and he tried to arrest … the EMT from taking my mother to the hospital.”

Richard O’Carroll, the lawyer for paramedic White, said that Trooper Martin abused his authority as a police officer. “Everything on this needs to relate back to why are we here? One man is there protecting a patient and one man is there abusing his authority and throwing his weight around,” said O’Carroll. White’s attorney filed a tort claim on behalf of his client in order to get the video of the police vehicle’s dash-cam released. Trooper Martin’s lawyer says he did not realize a patient was in the ambulance at the time of the incident.

O’Carroll explained the decision of paramedic White not to use sirens while transporting his patient to the hospital: “There was a reason he wasn’t running sirens. There was a suggestion of chest pains and a heart condition and sirens aggravate these conditions by increasing the blood pressure.” However the attorney for Trooper Martin, Gary James, said that the ambulance was not exempt from regulations because it did not have its sirens on. “If they’re not running their sirens or lights, they don’t get afforded any emergency vehicle exemptions,” said James. The OHP chief is handling an internal review into the incident. As of June 1, Trooper Martin has been on paid administrative leave.

Buffalo, New York —Wikinews has learned that, in a surprising turn of events, the city of Buffalo located in New York, has ordered and begun an emergency demolition on a three story 19th century stable which partially collapsed on Wednesday June 11 causing at least five homes to be evacuated. Residents are not happy, and despite the short notice of the demolition, nearly 30 people showed up to protest it. Demolition was not supposed to begin until Monday June 16.

At about 2:30 p.m. (eastern time) on June 13, demolition crew arrived at the stable located at 428 Jersey Avenue and began to unload heavy equipment which will be used to demolish the building. This came as a surprise to residents, as demolition was not supposed to start until Monday June 16.

During the early afternoon hours on June 11, the Buffalo Fire Department was called to scene after residents called 9-1-1 stating that part of the building had collapsed. Material from the building fell into the yards of at least three neighboring houses. Some of the bricks landed inside the building, while some fell into the yards of some houses behind homes on Richmond Avenue, leaving a ‘V’ shape.

At about 3:30 p.m. crews began to demolish a small portion of the stable located behind Joe Murray’s home, a resident who lives behind a portion of the building on Jersey and Richmond avenues. While demolition was taking place, the section collapsed into Murray’s backyard, prompting a call to police. Some residents who own home surrounding the building were inside Murray’s house holding a neighborhood meeting when demolition began. No one was injured when the section collapsed.

“[The building] can come down any minute,” stated Donna Berry of the Buffalo Police Department who also added that when police arrived on scene, they immediately put a stop to demolition, fearing the safety of surrounding residents and pedestrians.

“So many [of the] people [living around the building] are at risk, it makes me want to cry,” added Berry.

Police, local politicians and area residents are concerned that demolition crews and the city are not taking the proper precautions to ensure the safety of residents during demolition.

“[There is] no protection for neighbors. [This is] appalling and beyond negligence,” stated Tim Tielman, Executive Director of the Campaign for Buffalo who was referring to the negligence of the demolition crew.

“[In order to stop demolition] citizens must demonstrate direct harm to themselves,” added Tielman.

The city’s preservation board held an emergency meeting on Thursday to discuss the issue. Wikinews has learned that the owner of the building, Bob Freudenheim, gave the city permission to demolish the building because he would not be “rehabilitating the building anytime soon.” Freudenheim was part-owner of the Hotel Lenox at 140 North Street in Buffalo and was also an advocate to stop the Elmwood Village Hotel from being built on the corners of Forest and Elmwood Avenues in 2006 and 2007, which Wikinews extensively covered. He also financially supported a lawsuit in an attempt to stop the hotel from being built. Though it is not known exactly how long Freudenheim has owned the stable, Wikinews has learned that he was the owner while fighting to stop the hotel from being built.

Tielman states that he was in contact with Freudenheim this morning. Tielman states that Freudenheim “is not spending a dime” to have the building renovated. Tielman states that Freudenheim has offered to sell the building to any interested party for only one US dollar, but that he “flip flops [his decision] constantly,” sometimes wanting hundreds of thousands of dollars for the building. Wikinews has attempted to contact Freudenheim, but so far has been unsuccessful.

City building inspectors were also on scene evaluating the building and ensuring the safety of residents. Donald Grezebielucina states that “some people are on notice to vacate their properties”, but also stated that no other precautions were being taken other than placing “tires and scaffolding” onto the side of 430 Jersey, which sits less than eight feet from the buildings East side.

“The gas has been shut off in case we lost the building, so there would be no explosions or anything like that. It’s so unstable, the structural integrity is gone. The chemical composite of the trusses has changed dramatically and dry rotted. There are three vehicles in the basement which totally disappeared,” stated Grezebielucina to the press while protesters yelled “save our building, save our neighborhood.”

Wikinews has also learned that local residents have consulted a lawyer regarding the issue, and hope to petition the New York State Supreme court to issue an injunction to stop demolition. They states that Freudenheim should be “100% responsible” for his actions, and many are afraid that once the building is demolished, Freudenheim’s charges of neglect will be abolished. Freudenheim is facing housing violations for neglecting the building. Though residents are fighting, Tielman states that “an injunction is unlikely.”

“We had a letter of violation against him. He was supposed to have started work to stabilize the brick this Monday. We all hope this building could be saved. But we’ve got five houses evacuated and we cannot tolerate any further delay. We’ve got to get people back into their homes in a safe condition,” said Richard Tobe, Commissioner of the city’s Permit and Inspection Services.

Demolition is set to resume at 8:00 a.m.in the morning of Saturday June 14.

Mike Lombardo, the Commissioner for the Buffalo Fire Department, believes that the building was built in 1812 or 1814, making it nearly 200 years old. It is one of only three stables still standing in the city.

In a press release earlier today, New York State Agriculture Commissioner Patrick Hooker, along with Dean of Cornell University’s College of Veterinary Medicine Donald F. Smith, confirmed that scientists at the New York State Food Laboratory identified Aminopterin as a toxin present in cat food samples from Menu Foods.

Menu Foods is the manufacturer of several brands of cat and dog food subject to a March 16, 2007 recall.

Aminopterin is a drug used in chemotherapy for its immunosuppressive properties and, in some areas outside the US, as a rat poison. Earlier reports stated that wheat gluten was a factor being investigated, and officials now state that the toxin would have come from Chinese wheat used in the pet food, where it is used for pest control. Investigators will not say that this is the only contaminant found in the recalled food, but knowing the identity of the toxin should assist veterinarians treating affected animals.

The Food Laboratory tested samples of cat food received from a toxicologist at the New York State Animal Health Diagnostic Center at Cornell University. The samples were found to contain the rodenticide at levels of at least 40 parts per million.

Commissioner Hooker stated, “We are pleased that the expertise of our New York State Food Laboratory was able to contribute to identifying the agent that caused numerous illnesses and deaths in dogs and cats across the nation.”

The press release suggests Aminopterin, a derivative of folic acid, can cause cancer and birth defects in humans and can cause kidney damage in dogs and cats. Aminopterin is not permitted for use in the United States.

The New York State Food Laboratory is part of the Federal Food Emergency Response Network (FERN) and as such, is capable of running a number of unique poison/toxin tests on food, including the test that identified Aminopterin.

Investigators in Ireland have found wiring problems in several Virgin Atlantic Airbus A340s as part of their investigation into a fire on board one such aircraft that was forced to divert to Shannon Airport.

The Virgin jet was headed from London Heathrow Airport to Chicago with 143 passengers and thirteen crew on January 11 this year. A small fire was noticed in a waste bin storage area in the first class section’s bar unit.

A damaged wiring loom could be seen sticking out of a hole in the compartments floor, and there was visible electrical arcing in the area. An attempt was made to control the situation by switching off electrical circuits, but both the fire and the arcing continued unchecked.

The aircraft’s captain declared an emergency and diverted to Shannon, which the airliner reached thirty minutes later. During that time, the crew used five 1kg fire extinguishers upon the fire, but each time the arcing continued and after about five minutes the fire reignited. Witnesses described the fire as consisting of “licks of flame”.

After performing a safe emergency landing the airport’s Aircraft Rescue and Firefighting department tackled the fire with a 5kg extinguisher but met with similar results. After consulting with the crew the jet’s power was completely shut down, after which the fire was finally put out. Virgin initially claimed the fire had never occurred.

Investigators with Ireland’s Air Accident Investigation Unit (AAIU) inspected the loom and found it to be “completely severed” and exhibiting “strong evidence of burning/arcing” according to a preliminary report released on Friday. The loom was identified as providing power and dimming circuits for mood lighting in the bar.

The AAIU says that it seems the loom had contacted the metal waste bin in the compartment above. There should have been rails to hold up the bin and a protective metal cover, but “no evidence” of these was found and the report notes that “Initial inspection indicated the possibility that they were never fitted.”

The bar unit is a modification exclusive to Virgin. The AAIU ordered all 36 of the airline’s A340s worldwide inspected, with both France and the United Kingdom assisting with this. The UK has identified four other aircraft with faulty wiring, it has now been revealed. Virgin says that “A few minor issues were found and were immediately rectified,” and adds that “The installation of the bar was carried out in accordance with all relevant regulations. Virgin Atlantic continues to assist the AAIU in their investigation and looks forward to the full report with interest.”

The AAIU says that “significant other issues are being examined by the investigation” in addition to the wiring defects. “These include the difficulties faced by the crew in isolating the damaged circuits, the emergency checklist, the design of the modification and the standards relating to such modifications,” said the report.

Virgin’s Boeing 747-400 fleet also has a similar bar installed on it, but there was not considered to be a risk to the aircraft’s wiring on that model. The fire involved a bar added three years ago, with the aircraft manufactured in 1998.

Australian Prime Minister John Howard announced on Tuesday that Old Parliament House in Canberra has been heritage listed. It is the 31st entry on the National Heritage List.

The listing acknowledges the role the building has in shaping Australia’s culture and protects it from being modified in any way which could affect its historic value.

Old Parliament House served as the home of Australia’s parliament from 1927 until 1988, when it was relocated to the present parliament house. From 1901-1927, parliament met in Melbourne in the Victorian Parliament House (the state parliament was relocated for 26 years). Before being known as Old Parliament House, the building was known as Provisional Parliament House – as it was intended to be used for 50 years before a permanent building could be built.

In the 61 years the building was used as the seat of parliament, the government changed only seven times, and several new political parties were formed (the Liberals, Anti-Communist Labor Party, and the Australian Democrats).

Mr Howard said the building played an important part in Australia’s political history. “Old Parliament House will always be an important part of our political history with its rich collection of original furniture, art and memorabilia helping to illustrate the story of Australia’s political customs and functions,” he said.

According to Mr Howard, the National Heritage List lists sites which have helped shape the country. “The National Heritage List contains places that have played an important role in the development of our nation, such as Captain Cook’s landing place in New South Wales, Port Arthur in Tasmania and the Australian War Memorial in Canberra,” said the Prime Minister.

The building currently houses Australia’s National Portrait Gallery, and serves as a venue for receptions and exhbitions.

The Australian federal and New South Wales governments will not be selling their shares in Snowy Hydro Limited (the owner and operator of the Snowy Mountains Hydro-Electric Scheme). Snowy Hydro Limited’s major shareholder is the NSW government with a 58 percent shareholding. The Victorian government owns 29 percent and the federal government has a 13 percent stake.

NSW Premier Morris Iemma announced in December 2005 that he wished to sell the state’s share in Snowy Hydro that caused the federal and Victorian governments to follow.

The proposed sale has attracted immense criticism by those who believed that the sale would affect the environment and water supplies along the Snowy River, this was reinforced yesterday when 58 eminent Australians presented a petition to the government opposing the sale.

Prime Minister John Howard announced today that the federal government would not be selling its 13 percent share of Snowy Hydro following what he calls “intense community reaction”. In a statement, Mr Howard said, “This decision to sell the Snowy Hydro has created significant unhappiness, concern and unrest throughout the Australian community.”

Mr Howard said that the sale was not an election promise by his government and that the federal government failed to see any long-term benefits from the sale. He also said that the government needed to “safeguard the interests of all those dependent on Australia’s iconic water resources”.

The federal government has however stated that despite refusing to sell its share in Snowy Hydro that it will not be purchasing additional shares if NSW and Victoria push ahead with the sale of their shareholdings.

Despite telling Macquarie Radio earlier this morning that his government would be pushing ahead with the sale as it was in the best “interests of NSW”, Premier Iemma announced shortly after Mr Howard’s release, that the NSW government would be withdrawing its shares from sale.

Mr Iemma conceded that the sale would be extremely difficult with the federal government withdrawing its 13 percent from sale. “The Prime Minister has pulled the rug out from under the sale,” Mr Iemma said. “The circumstances are significantly changed.”

“The Commonwealth decision makes it extremely difficult for NSW to proceed,” he conceded.

Victoria is yet to announce whether or not it will be withdrawing its shares from sale.
