Scientists are discovering a "strange" way to eliminate cancer

Scientists are discovering a "strange" way to eliminate cancer


LONDON (Reuters) - Scientists at the University of Surrey have discovered what could be a "breakthrough" in the fight against cancer, where they discovered a strain of the common cold virus had destroyed cancerous tumors.

In a university experiment involving patients in the early stages of cancer, scientists succeeded in using the "Coxsaki" virus, a strain of the common cold virus, which injected it into patients' cysts.
A week later, researchers found that this cold virus successfully targeted cancer cells and caused their destruction and death, according to the newspaper "Daily Star" British.

According to documents summarizing the medical experiment published in the Journal of Clinical Cancer Research, the disease disappeared completely in a patient who had bladder cancer, and showed no trace of the disease after the innovative treatment.

In addition, there were no side effects in any of the patients, not to mention that the healthy cells around the tumors remained unchanged and was not affected by the treatment targeted only cancer cells, knowing that most of the treatments available to cancer patients currently can cause serious side effects.

"The method of treatment works by heating the tumor and recruiting all the immune cells in the right place," said University of Pennsylvania professor of research Prof. Hardev Panda.
Hardiff said the findings were surprising to researchers who expressed the hope that this breakthrough would "revolutionize the treatment" of the deadly disease.

A bladder cancer charity described the study as "very exciting", especially if other, larger studies confirmed the findings.

"If it is possible to confirm the safety data and the various possibilities and the effectiveness of this procedure through further studies and clinical trials, it can promise a new era in the treatment of bladder cancer," said Alan Knight, chairman of the British Cancer Society.

The UK Cancer Research Center said the findings were "encouraging".

Cigarette .. How to kill smokers in terms of "do not expect"?


Smoking is one of the leading causes of inevitable death, as it is strongly associated with diseases and damage to the lungs.

However, a recent study revealed that cigarettes can also damage the cardiovascular system, or circulatory system, according to the Medical Daily website.

Researchers at the National University of Australia said smokers were three times more likely to die of heart disease or blood circulation than nonsmokers.

Direct exposure to cigarette smoke could increase the risk of a heart attack, stroke or myocardial infarction by about twice as much, the researchers said.

It is noteworthy that the risk of disease increases in people who smoke 5 cigarettes a day on average.

"We have found that there is no way to escape or hide," said Emily Banks, head of the research team and professor at the National Center for Population Health and Epidemiology. "Smoking causes great harm to everyone."

The study, published in the journal BMC, is the most profound study of the effects of harmful smoking on the cardiovascular system in the world.

The conclusion came after analyzing the health data of more than 190 thousand smokers and non-smokers in Australia, have been followed for more than 7 years, knowing that statistics indicate that there are about 2.7 million smokers in Australia.

In their study, researchers aimed to find out how smoking contributes to 36 different types of heart disease or circulatory system diseases.

After follow-up, the research team recorded a link between smoking and an average of 11,400 coronary heart disease cases referred to hospitals for treatment.

The researchers said as many as 17 Australians die daily from heart attacks, strokes and other cardiovascular diseases caused by smoking.

"This new evidence is a cause for concern," said John Kelly, chief executive of the National Heart Foundation in Australia, adding that "our battle to eliminate the devastation tobacco has caused to people's lives is not yet over."

Kelly stressed that the government should consider tobacco control a top priority and include it in the country's new prevention strategy.

The study recommended the need to quit smoking, if people want to reverse the risk of cardiovascular disease.

"Quitting smoking at any age provides a number of health benefits," said Sarah White, director of the Stop Smoking Victoria Foundation.

She said the chance to stop smoking for those over the age of 45 years remained, noting that this would reduce the risk of cardiovascular diseases associated with cigarettes, by 90 percent.

The science behind California’s two big earthquakes

The science behind California’s two big earthquakes


The science behind California’s two big earthquakes

On the morning of July 4, a magnitude 6.4 rocked Southern California, fracturing roads and sending people fleeing to safety. But that wasn’t all the Earth had in store: Less than a day and a half later, a powerful magnitude 7.1 temblor shook the region.
While earthquakes are not unexpected, the two most recent temblors are the largest that have struck this area in decades. And they promise to yield fresh clues about its complex geology.
The duo of quakes struck in what’s known as the Eastern California shear zone—an area east of the infamous San Andreas fault, where the Pacific Plate grinds against the North American Plate, creeping northwest at roughly two inches each year. The area extends from the southern Mojave Desert, up the eastern side of the Sierra Nevada, and into western Nevada. It’s crisscrossed by fractures in the Earth caused by the movement along the nearby tectonic plate boundary.
“The Eastern California shear zone is a really interesting area,” says Wendy Bohon, an earthquake geologist at the Incorporated Research Institutions for Seismology (IRIS). “How is it working? How is it accommodating plate motion? What are going to be the big structures that come out of this millions of years down the road?”

EARTHQUAKES 101Earthquakes are unpredictable and can strike with enough force to bring buildings down. Find out what causes  earthquakes, why they're so deadly, and what's being done to help buildings sustain their hits. 

What happened?

The recent events are what’s known as strike-slip earthquakes, which occur when two blocks of Earth shift side-by-side, grinding past each other. They seemed to have occurred along the same set of faults, located in an area known as the Little Lake fault zone.
While no deaths or major injuries have yet been reported, the intensity of the ground movement was quite strong—enough to send goods flying off store shelves and buildings swaying. The shaking was also widespread, with reports of light ground movements as far as Chico, California, and Phoenix, Arizona.
Of particular interest in these quakes is that at least the first temblor seemed to have simultaneously broken two sections of faults that cut across each other at nearly a right angle. While such complex quakes are not unheard of, recent research suggests that they may be more common than once believed, explains Zachary Ross, a geophysicist at the California Institute of Technology.
“Historically, the thought has been that earthquakes occurred on individual faults,” he says. “And then over time, as the data has gotten better and better, we’ve started to realize that there’s potential for multiple faults to rupture for single events.”
This shift in thinking was propelled by the magnitude 7.3 earthquake that shook Landers, California, in 1992. This temblor fractured along at least five fault segments. Subsequent earthquakes have revealed similar complex breakage, including the magnitude 7.2 earthquake in 2010 in Baja California, Ross notes. This latest quake is further evidence that this complexity is common, even for smaller magnitude events.

Why did two big earthquakes strike?

In most circumstances, big earthquakes strike in a familiar sequence: There’s a large earthquake followed by a series of smaller events. That’s because the movement that occurs during a large earthquake causes increased strain in the surrounding region. Earthquakes are the Earth’s way of relieving this strain.
But in some circumstances, such as the recent pair of earthquakes in California, a relatively large temblor might just be the forerunner for even bigger event. While the difference between 7.1 and 6.4 may seem minor, magnitude is a logarithmic scale. An increase of a unit of magnitude is about 32 times more energy, which means that the second earthquake released roughly 11 times the energy of the first temblor.
Scientists think of this series of earthquakes as the foreshock, the mainshock or strongest event, and then the aftershocks, explains Susan Hough, a seismologist with the U.S. Geological Survey.
“But it’s way too simplistic,” she notes.
Every earthquake causes a shift in the landscape, redistributing the strain in the crust, which means all earthquakes could trigger other earthquakes. “Whether or not an earthquake itself is an aftershock,” she says, “you can think of it as a potential [earthquake] parent.”
The likelihood that a big earthquake will trigger a larger event is roughly one in 20, according to Hough. That’s definitely a low risk. “But that one in 20 isn’t zero,” she says.
Scientists, however, are still untangling the connection between the recent events. The magnitude 7.1 temblor seemed to break along the the northwest-southeast limb of the pair of faults that ruptured earlier, Hough notes, extending farther than the first quake in both directions.
“Major scientific questions: Did part of the fault break and then break again? How did breaks compare in detail?” she writes on Twitter. Finding the answers to these questions could have important implications for understanding the hazards of these events.
“This appears to be the clearest case I've seen that that did indeed happen,” she says of the same fault rupturing more than once in a short time period. “But much work is needed to sort out the details.”

What’s going to happen next?

So far, many more than a thousand aftershocks have rippled through the region. While the frequency and intensity of subsequent temblors will wane, Southern California likely has more shaking in store. “A magnitude 7 is going to produce activity for years,” Ross says.
The USGS estimates that over the course of the next week, between 240 and 410 earthquakes of magnitude 3 or higher will likely ripple through the region. These are events just large enough to feel if you are positioned close to their epicenter. As for larger earthquakes, the probability becomes increasingly small, but not out of the question.
The USGS estimates that there’s a 24 percent chance that as many as two earthquakes magnitude 6 or larger could strike in the next week. But as scientists continue to analyze these events, they may adjust those numbers.
Such a strong series of aftershocks is not unexpected. “Earthquakes out in the Mojave Desert traditionally have these bigger, robust aftershocks sequence,” Bohon says.
She cautions, however, that all of these probabilities are forecasts and not predictions. No one, despite what some claim, can predict future earthquakes. She likens the difference to weather forecasts, which are an estimate of the probability that something might happen.
“You would never predict the weather,” she says. “You can’t predict with 100 percent certainty that it [will be] raining unless it’s raining. And earthquakes are very similar.“
Bohon emphasizes that it’s normal to be scared during an earthquake, which can rock the ground like a boat in rough water. But as aftershocks ricochet through Southern California, she suggests people who live in earthquake-prone regions check how prepared they are for the next event.
“This was a good scenario earthquake,” says Bohon. “It was in a fairly unpopulated area, but a lot of people felt it.” Bohon hopes that means those who experienced it are getting ready for the next one.

Frederick Sertner ... Pharmacist ridiculed the God of Dreams to relieve pain

Frederick Sertner ... Pharmacist ridiculed the God of Dreams to relieve pain

Frederick Sertner ... Pharmacist ridiculed the God of Dreams to relieve pain


We have all heard of morphine, a hypnotic drug derived from poppy extract, which is prepared from raw opium. It allows doctors to use it to relieve pain but within certain limits so that the patient does not reach the stage of addiction. Morphine was first detected by Austrian chemist Frederick Sertner in 1804, who isolated morphine from raw opium in the first precedent of isolating an effective plant. Sertner launched the property Morpheus, the god of dreams of the Greeks.
Morphine pills work directly on the central nervous system and reduce the feeling of acute or chronic pain

Born in Prussia, in 1783, Sertner died at the age of 15 and left him without a means of support.

In 1803, Frederick was a young man of 20 who trained on pharmacy practice after receiving a limited education. However, through diligent research, he succeeded in isolating and extracting morphine crystals from opium, which he described as the "sleeping agent" of opium and hence derived his name from the name of the god of dreams. Sertner's discovery had a great impact, enabling doctors to prescribe morphine in specific and regulated doses.

Sertner's experiments were very discreet, at night alone, and mice and stray dogs were introduced in experiments to monitor the effects of morphine on live animals. To determine a suitable dose for humans, Sertner recruited some of his friends to try morphine on them in a series of controlled trials. He himself participated in the trials and watched and recorded the effects of the drug during increasing doses. Experiments have revealed that half of the morphine cause a feeling of happiness along with a sense of dizzyness.

The second dose causes drowsiness and excessive fatigue. The third dose causes confusion and loss of concentration followed by falling into a deep sleep, followed by suffering from nausea and headache when waking up. Although his friends refused to continue the experiments, Sertner continued to experiment with the drug for months without realizing that his medication was causing severe addiction.

Sertner continued to pursue his career in pharmacy, and in 1806 he published two articles on his morphine experiences, but was largely ignored. By 1809 he became a licensed pharmacist and owner of a private company. He published a report on his experiences with morphine for the third time, describing his findings in much greater depth. The report received considerable attention and earned an honorary doctorate from the universities of Gina, Marburg, Berlin, St. Petersburg, Batavia, Paris and Lisbon. He was also awarded the Montaigne Prize for his achievement in isolating morphine from opium "useful to humanity". Despite these awards and awards, some factions in the German medical community have refused to acknowledge the importance of Sertner's discovery and have been critical of him and underestimate his research. Scientific journals did not welcome the publication of his writings, although many of his theories and conclusions later proved correct. For example, during the cholera epidemic, he pointed out that the cause of the epidemic was a living organism.

Despite the importance of his research, Sirtorner suffered from chronic depression and judged himself to fail because he could not develop a safe and effective dwelling that would kill the pain without making the patient unconscious. He withdrew from social life and was suffering from thyroid pain and was dependent on morphine until the side effects became unbearable He died at age 58.

But medical historians have returned to Sertner's right and recognized the importance of his work, especially in the light of the constraints he faced, his research was accomplished with a superficial medical background and limited resources, a guide and testimony to his genius and passion and extraordinary abilities.
