University Of Southampton Researchers: Salt Injection Kills Cancer Cells

Salt Injection ‘Kills Cancer Cells’ – News AU

Scientists have created a technique which can cause cancer cells to self-destruct by injecting them with salt.

Researchers from the University of Southampton are part of an international team that has helped to create a molecule that can cause cancer cells to die by carrying sodium and chloride ions into the cells.

Synthetic ion transporters have been created before but this is the first time researchers have demonstrated how an influx of salt into a cell triggers cell death.

These synthetic ion transporters, described this week in the journal Nature Chemistry, could point the way to new anti-cancer drugs while also benefiting patients with cystic fibrosis.

“This work shows how chloride transporters can work with sodium channels in cell membranes to cause an influx of salt into a cell. We found we can trigger cell death with salt,” said study co-author Professor Philip Gale, of the University of Southampton.

Cells in the human body work hard to maintain a stable concentration of ions inside their cell membranes. Disruption of this delicate balance can trigger cells to go through apoptosis, known as programmed cell death, a mechanism the body uses to rid itself of damaged or dangerous cells.

One way of destroying cancer cells is to trigger this self-destruct sequence by changing the ion balance in cells.

Unfortunately, when a cell becomes cancerous, it changes the way it transports ions across its cell membrane in a way that blocks apoptosis.

The researchers have overcome this by developing the synthetic way for transporting the ions but unfortunately this also destroys healthy cells which would have to be overcome for it to be useful in treating cancer.

Prof Jonathan Sessler, at Austin’s College of Natural Sciences at the University of Texas, said: “We have thus closed the loop and shown that this mechanism of chloride influx into the cell by a synthetic transporter does indeed trigger apoptosis.

“This is exciting because it points the way towards a new approach to anti-cancer drug development.”

Yale Scientists Use Arthritis Medication To Regrow Bald Man’s Hair

Scientists Successfully Use Arthritis Drug To Regrow Completely Bald Man’s Hair – Daily Mail

Yale scientists have successfully used an arthritis medication to fully regrow the head and body hair of a almost totally hairless 25-year-old man.

Researchers administered the drug tofacitinib citrate to the unnamed patient, who suffered from the autoimmune baldness disease alopecia universalis.

Within eight months, the man had regrown scalp and facial hair he’d not had in seven years.

‘The results are exactly what we hoped for,’ said Brett A. King, M.D., senior author of the paper, published in the Journal of Investigative Dermatology. ‘This is a huge step forward in the treatment of patients with this condition.’

.

Unbelievable: Yale University researchers correctly guessed that a rheumatoid arthritis drug called Xeljanz could successfully regrow hair in a patient with the autoimmune disease alopecia universalis, which causes hairlessness over the whole body. This 25-year-old took the drug and by the end of eight months had all the hair back on his head, body and face that he hadn’t had in years

.

Huge success: The drug had successfully been used before on plaque psoriasis, which the 25-year-old Yale patient also exhibited, but had never been used to treat alopecia in humans

.
The man was referred to Yale Dermatology in New Haven, Connecticut to deal with an autoimmune disease that coincided with his alopecia, plaque psoriasis, according to a department news release.

Believing both his ailments could be alleviated with the same drug, researchers administered tofacitinib, made by Pfizer under the brand name Xeljanz, which is already FDA approved for the autoimmune disease rheumatoid arthritis.

According to Science World Report, the drug had successfully been used to treat psoriasis in people and alopecia in mice.

But the results were nonetheless shocking.

Photos of the man show him go from totally bald on top of his head to sporting a lustrous mane of blond locks.

‘There are no good options for long-term treatment of alopecia universalis,’ said King. ‘The best available science suggested this might work, and it has.’

The patient took 10mg per day for two months followed by 15mg per day for another three months.

By the end, he’d completely regrown scalp hair, developed eyebrows, eyelashes and facial hair, armpit hair and other hair.

‘By eight months there was full regrowth of hair,’ said co-author Brittany G. Craiglow, M.D. ‘The patient has reported feeling no side effects, and we’ve seen no lab test abnormalities, either.’

According to King, scientists believe the drug works by turning off the immune attack on hair follicles.

The authors said the drug helps in some but not all instances of psoriasis.

Scientists In The Netherlands Report Finding Reliable Way To Teleport Data

Scientists Report Finding Reliable Way To Teleport Data – New York Times

Scientists in the Netherlands have moved a step closer to overriding one of Albert Einstein’s most famous objections to the implications of quantum mechanics, which he described as “spooky action at a distance.”

In a paper published on Thursday in the journal Science, physicists at the Kavli Institute of Nanoscience at the Delft University of Technology reported that they were able to reliably teleport information between two quantum bits separated by three meters, or about 10 feet.

Quantum teleportation is not the “Star Trek”-style movement of people or things; rather, it involves transferring so-called quantum information – in this case what is known as the spin state of an electron – from one place to another without moving the physical matter to which the information is attached.

Classical bits, the basic units of information in computing, can have only one of two values – either 0 or 1. But quantum bits, or qubits, can simultaneously describe many values. They hold out both the possibility of a new generation of faster computing systems and the ability to create completely secure communication networks.

Moreover, the scientists are now closer to definitively proving Einstein wrong in his early disbelief in the notion of entanglement, in which particles separated by light-years can still appear to remain connected, with the state of one particle instantaneously affecting the state of another.

They report that they have achieved perfectly accurate teleportation of quantum information over short distances. They are now seeking to repeat their experiment over the distance of more than a kilometer. If they are able to repeatedly show that entanglement works at this distance, it will be a definitive demonstration of the entanglement phenomenon and quantum mechanical theory.

Succeeding at greater distances will offer an affirmative solution to a thought experiment known as Bell’s theorem, proposed in 1964 by the Irish physicist John Stewart Bell as a method for determining whether particles connected via quantum entanglement communicate information faster than the speed of light.

“There is a big race going on between five or six groups to prove Einstein wrong,” said Ronald Hanson, a physicist who leads the group at Delft. “There is one very big fish.”

In the past, scientists have made halting gains in teleporting quantum information, a feat that is achieved by forcing physically separated quantum bits into an entangled state.

But reliability of quantum teleportation has been elusive. For example, in 2009, University of Maryland physicists demonstrated the transfer of quantum information, but only one of every 100 million attempts succeeded, meaning that transferring a single bit of quantum information required roughly 10 minutes.

In contrast, the scientists at Delft have achieved the ability “deterministically,” meaning they can now teleport the quantum state of two entangled electrons accurately 100 percent of the time.

They did so by producing qubits using electrons trapped in diamonds at extremely low temperatures. According to Dr. Hanson, the diamonds effectively create “miniprisons” in which the electrons were held. The researchers were able to establish a spin, or value, for electrons, and then read the value reliably.

In addition to the possibility of an impregnable quantum Internet, the research holds out the possibility of networks of quantum computers.

To date, practical quantum computers, which could solve certain classes of problems far more quickly than even the most powerful computers now in use, remain a distant goal. A functional quantum computer would need to entangle a large number of qubits and maintain that entangled state for relatively long periods, something that has so far not been achieved.

A distributed quantum network might also offer new forms of privacy, Dr. Hanson suggested. Such a network would make it possible for a remote user to perform a quantum calculation on a server, while at the same time making it impossible for the operator of the server to determine the nature of the calculation.
