Nose cell transplants allow paralyzed dogs to walk again

Nose cell transplants allow paralyzed dogs to walk again | Longevity science | Scoop.it

Scientists from the University of Cambridge’s Veterinary School, working with colleagues from the UK Medical Research Council’s Regenerative Medicine Centre, have got disabled dogs walking again.

 

More specifically, they’ve used the dogs’ own cells to repair their spinal cord injuries, and at least partially restored the functionality of their back legs. The researchers believe that the process shows promise for use on physically challenged humans.

Fish Oil May Help Seniors Stay Strong

After six months, the women who took fish oil supplements had developed significantly higher blood levels of omega-3 DHA and lower levels of omega-6 AA (a generally pro-inflammatory fatty acid).
 
And, compared to the placebo group, the fish oil group showed improvements in walking speed and reduced levels of a key marker for inflammation (TNF-alpha).
Ray and Terry's 's insight:

Vital Choice publishes an excellent newsletter. They report on many nutritional research studies. Highly recommended.

Injected bacteria found to reduce tumors in rats, dogs and humans

Injected bacteria found to reduce tumors in rats, dogs and humans | Longevity science | Scoop.it

Bacteria found in soil called Clostridium novyi (C. novyi) is known to cause tissue-damaging infections. But researchers from John Hopkins Kimmel Cancer Center have developed a modified version that triggers an anti-tumor response in rats, dogs and humans. The breakthrough could complement existing methods to provide better targeted treatment of cancerous growths.

Anti-Anxiety Drug Makes Fish Live Longer

Anti-Anxiety Drug Makes Fish Live Longer | Longevity science | Scoop.it

On the one hand, fish exposed to the tranquilizer oxazepam when it seeps into their waters kind of become jerks, reports a study in Nature. On the other hand, this same drug, a benzodiazepine used to treat anxiety and insomnia in human adults, apparently helps them live longer, reports Nature World News, citing a study published in the journal Environmental Research Letters. This news may be, from a longevity standpoint, terrific for the tainted fish—but it's not ideal for keeping the entire ecosystem's mortality rates balanced and the food chain intact.



Ray and Terry's 's insight:

One question: Do we want to become tranquilized jerks to live longer? More research is needed :)

Gastroenterology & Endoscopy News - ‘Good Vibrations’ Might Ease Constipation

A remotely activated vibrating capsule can relieve chronic constipation and might be a good alternative for patients reluctant to try the latest pharmacologic treatments for the condition, Israeli researchers have found.


“This is an example of thinking outside the box. It’s an innovative idea,” said Yishai Ron, MD, director of neurogastroenterology and motility at Tel Aviv Sourasky Medical Center. “You swallow this capsule. It’s not absorbed. It does not cause side effects, unlike all the medications currently used for treating constipation.”

Yoga Gave Aging Brains a Boost

New study finds that yoga can benefit aging brains
The recent University of Illinois study involved 108 adults between the ages of 55 and 79, of whom 61 attended hatha yoga classes.
The other volunteers met for the same number and length of sessions, but they engaged in stretching and toning exercises instead of yoga.
At the end of the eight weeks, the yoga group was speedier and more accurate on tests of information recall, mental flexibility and task-switching than it had been before the intervention.
In contrast, the stretching-and-toning group saw no significant change in cognitive performance over time.

Spongy polymer developed to fill holes in bones

Spongy polymer developed to fill holes in bones | Longevity science | Scoop.it
Whether they're the result of injuries, surgery or birth defects such as cleft palate, missing sections of bone in the skull or jaw can certainly affect someone's appearance. Although there are some methods of filling in such gaps, they have limitations that limit their application. A newly-developed foam-like material, however, may be able to succeed where other approaches have failed.Usually, bone defects in the head, face or jaw are filled using either bone harvested from another part of the patient's body (such as the hip), or a material such as bone putty.

Synthetic molecule uses salt to trigger self-destruction of cancer cells

Synthetic molecule uses salt to trigger self-destruction of cancer cells | Longevity science | Scoop.it
A team of international researchers has developed a molecule capable of triggering cancer cell death by carrying chloride into cancer cell membranes. The molecule flushes the cells with salt and causes them to self-destruct, potentially paving the way for new types of anti-cancer drugs.The international effort involves researchers from the UK, Texas and South Korea who have collaborated to develop a synthetic ion transporter with a chloride payload. Once it reaches the cancer cells, the chloride interacts with the sodium in the cell membranes and leads to its demise.

Study finds a gene mutation increases breast cancer risk to 1 in 3

 Women with mutations in a gene called PALB2 have a one in three chance of developing breast cancer by age 70, according to research that suggests PALB2 is almost as important a risk factor as BRCA1 or BRCA2 mutations.BRCA1 and BRCA2 are widely known as breast cancer risk genes. Women with a mutation in one or both often decide to have their breasts removed so they do not develop the disease.
