Repairing the Nervous System with Stem Cells

July 18, Sources ft corridor leading to her cell cordoned off: Sources VIP treatment in prison for politician VK Sasikala includes five cells near hers being kept empty to ensure her privacy, a flat-screen television in her cell, and access to unused chambers of jail officials for meetings with visitors, according to sources inside Karnataka’s prison system. The details have emerged along with photographs and a video that first aired on local channels that show a foot-long corridor which leads to the year-old’s cell which is reportedly kept clear at all times and is barricaded off at both ends, allowing Ms Sasikala a suite of rooms. Allegations of the largesse of facilities showered upon Ms Sasikala led to senior police officer D Roopa losing her job yesterday as Deputy Inspector General of Prisons. She has instead been assigned the far more prosaic charge of traffic and road safety in Bengaluru. On Thursday, the young police woman alleged that Ms Sasikala had bribed senior jail officials with 2 crores for special treatment that included a kitchen that catered meals only for her.

Share shares These animals also had fewer tumours and the tumours they did develop were smaller than their untreated counterparts. Of the mice who were given resveratrol but did not have cancer at the start of the treatment, 37 per cent went on to develop the disease. It means even following safe drinking guidelines of 14 units a week could be enough to endanger health.

There is still no accurate atlas of human cell types. How many types of cells are there in the human body? Textbooks say a couple of hundred. But the true number is undoubtedly far larger. A.

By Nathaniel Scharping January 9, 2: GSK-3 inhibitors are thought to reduce the number of beta-amyloid plaques and tau proteins in the brain. Filling in a cavity with real tooth material is far preferable, not only because it lasts longer, but because a whole tooth is also much healthier. The sponges were gone, and in their place was new, healthy dentin.

In June of last year, researchers from the University of Nottingham and the Wyss Institute at Harvard won a prize from the Royal Chemistry Society for a similar approach. Beyond the Tooth Dental stem cells could be used for more than just creating dentin. There has been interest in using the cells to grow whole teeth, and the range of applications could extend to other parts of the body as well.

Mesenchymal stem cells, of the kind found in the tooth, can form bone, cartilage, muscle and fat cells in addition to the odontoblasts they create in teeth. For now, the researchers are expanding their study to rats — they have larger teeth — to see how well the collagen sponges hold up in their cavities. Someday soon, we might fill the largest cavities with the tooth, the whole tooth, and nothing but the tooth.

Nanomachines that drill into cancer cells killing them in just 60 seconds developed by scientists

In laboratory tests, researchers showed how the molecules can be activated by ultraviolet light to spin up to three million times a second and drill through cell membranes. In one test, it took between one and three minutes to cut through the outer shell of prostate cancer cell and destroy it. Another application for the tiny ‘nanomachines’ might be to deliver therapeutic medicines, researchers say.

A sequence of images taken over 10 minutes shows a human prostate cell under attack by motorized molecules. The cell, tagged with a green fluorescent protein, is made permeable by the nanomachines, which drill through its lipid bilayer membranes.

Structure[ edit ] Cross-section of bone Bone is not uniformly solid, but includes a tough matrix. Its matrix is mostly made up of a composite material incorporating the inorganic mineral calcium phosphate in the chemical arrangement termed calcium hydroxylapatite this is the bone mineral that gives bones their rigidity and collagen , an elastic protein which improves fracture resistance. When these cells become entrapped from osteoblasts they become osteocytes.

It forms the hard exterior cortex of bones.

Jul 10,  · A cocktail of leukemia medicine and the herbal supplement quercitin extended lifespan in mice and in human cells. This compound also reduced frailty and other aspects of aging-related illness.

Stem Cells without the Embryos An easy method for reprogramming adult cells may resolve ethical objections. The method could provide a way to make patient-specific stem cells, a feat not yet achieved in humans. Such cells could eventually be used for studying complex genetic diseases, or for cell or tissue transplants without fear of immune rejection. Researchers at the University of Wisconsin-Madison successfully reprogrammed skin cells shown here to act like embryonic stem cells.

The new technique also removes the major ethical objections to embryonic stem-cell research: For reasons not yet clear to scientists, exposing cells to these genes appears to turn back the developmental clock. Both groups found that the resulting cells exhibit two major properties that define embryonic stem cells.

The immune system is a host defense system comprising many biological structures and processes within an organism that protects against function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism’s own healthy many species, the immune system can be classified into.

And it’s pointing to a cosmic birth, more violent than we ever imagined. You know what you want to make, but you don’t have a recipe. For decades, we’ve been trying to cook up the building blocks of life, in the lab, and recreate the origins of it all, but the parts didn’t seem to fit together, until now.

We were the guys who stood back, and looked at it in a different way. One team may have retraced a key step in the birth of life, itself. How did they do it?

Paul Berry After building the product for Huffington Post, and owning the product and engineering groups at AOL after we were acquired, it was clear to me there was a huge gap between what the current CMS offering gave the world and what the world needed. Five years later we are at scale, moving the needle and doing to WordPress what Airbnb did to Craigslist. Social and Centralized WordPress, Drupal, and the custom CMS solutions of the world are all independent, non-connected instances that each need to be updated individually.

There are over 87 million instances of WordPress alone in the world, and each security upgrade, feature update, and every other single thing has to be updated for each site individually. By contrast, RebelMouse is a social, centralized platform built to keep up with the speed of the tech giants.

By Vilma Ruddock M. How long marijuana stays in your system depends on a variety of factors. How often you smoke, your rate of metabolism, and your general health and weight all have an effect on how long it takes before marijuana is out of your system. Varied Timeframe According to the experts at WebMD , the amount of time marijuana stays in your system is anywhere from a week to a month, depending on how often you use it and a number of other variables.

Factors That Affect How Long Weed Is Detectable Depending on your pot habit and other factors, evidence of marijuana cannabis can be detected in your body systems anywhere from a few days to several weeks after your last use of the drug. If you are a light, occasional user, weed might be out of your system within two to four days or up to a week. If you are a chronic, heavy user, it might take a few weeks and even up to three months to get pot out of your system after last use. Marijuana Potency According to the National Institute on Drug Abuse , the amount of THC tetrahydrocannabinol in the marijuana you smoke could be a factor in how long the drug remains in your body.

The drug potency depends on the potency of the THC.
