A team of researchers from the Center of Regenerative Medicine in Barcelona (CMRB), the Salk Institute in California and the Hospital Clinic in Barcelona creates three-dimensional kidney structures in culture using human stem cells.
Last week I discussed the homeopath’s preparation for a second consultation with a patient, and how the patient’s report might be assessed. This week, let’s look a little more closely at the patient herself.
Sharon Terry, President and Chief Executive Officer of Genetic Alliance, asserts, "I find myself becoming increasingly optimistic that we are approaching a tipping point for the consumer movement in health." ["Big Data Is Good for Your Health,"...
Trials of the technology are still in the early stages, but better-than-expected results raise prospects of saving limbs lost in accidents or eventually overcoming paraplegia and quadriplegia.
St Vincent’s Hospital researchers have built and implanted a bridge between severed nerves in areas too large and complex to be healed by conventional nerve grafts.
After successfully restoring the feeling and partial use of legs in rats missing the main nerve to their limbs, director of neurosciences Prof Mark Cook said new trials had begun to see how far the technology can allow nerves to regrow in the hope it can be expanded to humans studies in the next two to five years.
It has long been assumed in the BI community that more information is "a good thing" when it comes to making better decisions. Except when there is too much information...when we encounter information overload.This leads us to look beyond information as the sole or, even, majority basis for decision making. Rational choice theory has long held sway as the foundation of thinking about business decision making. In recent years, the roles of intuition, gut-feeling, emotional state and intention are slowly coming to the fore as possible contributors.
If better health isn’t enough incentive to take a brisk walk, perhaps there is another one: it may get you a better deal.
New research from the Massachusetts Institute of Technology offers a twist on the adage “never let them see you sweat,” says Jared Curhan, associate professor of organization studies at M.I.T.’s Sloan School of Management, and one of the study’s co-authors. “If you’re sweating, and your heart rate is up, it’s seen as a sign something is going wrong, that you’re too nervous, off-balance, flustered,” he said. “Whereas we’re showing that something could be very right.”
Intestinal microbiota contributes to diverse mammalian processes including the metabolic function of drugs. It is a potential new territory for drug targeting, especially for dietary herbal products. Because most of herbal drugs are orally administered, the chemical profile and corresponding bioactivities of herbal medicines may be altered by intestinal microbiota.
Anyone who has left youth behind them knows that bumps and scrapes don't heal as fast as they used to. But that could change with researchers at the Stem Cell Program at Boston Children's Hospital finding a way to regrow hair, cartilage, bone, skin and other soft tissues in a mouse by reactivating a dormant gene called Lin28a. The discovery could lead to new treatments that provide adults with the regenerative powers they possessed when very young.
Lin28 is a gene that is abundant in embryonic stem cells and which functions in all organisms. It is thought to regulate the self-renewal of stem cells with the researchers finding that by promoting the production of certain enzymes in mitochondria, it enhances the metabolism of these cellular power plants that found in most of the cells of living organisms. In this way, Lin28 helps generate the energy needed to stimulate the growth of new tissues.
"We already know that accumulated defects in mitochondrial metabolism can lead to aging in many cells and tissues," says Shyh-Chang Ng. "We are showing the converse – that enhancement of mitochondrial metabolism can boost tissue repair and regeneration, recapturing the remarkable repair capacity of juvenile animals."
A recent study suggests that a high intake of fruits and vegetables is associated with a lower risk of bladder cancer—but only in women.
The findings come from the Multiethnic Cohort Study, a longitudinal survey that, since 1996, has collected data on diet, lifestyle, and genetic factors from more than 215,000 adults between the ages of 45 and 75 in Hawaii and California and searched for links to cancer incidence. The study cohort includes African-Americans, Japanese-Americans, Latinos, Native Hawaiians, and whites.
Although prospective cohort studies found no relationship, past case-control studies have reported an inverse relationship between the incidence of bladder cancer and the intake of fruits and vegetables.
These studies had been conducted in ethnically homogenous populations, primarily Europeans; therefore, the Multiethnic Cohort Study provided an opportunity to investigate the relationship in an ethnically diverse population.
This analysis drew on data from more than 185,000 participants in the study. Dietary data was collected on self-report questionnaires. Subjects were followed for 12.5 years, during which 581 cases of bladder cancer were recorded.
Breast cancer is one of the most common forms of cancer and cancer deaths among women worldwide. Routine screening can increase breast cancer survival by detecting the disease early and allowing doctors to address it at this critical stage.

f effective, the new device, called a photoacoustic mammoscope, would represent an entirely new way of imaging the breast and detecting cancer. Instead of X-rays, which are used in traditional mammography, the photoacoustic breast mammoscope uses a combination of infrared light and ultrasound to create a 3-D map of the breast. The researchers describe their device in a paper published today in The Optical Society's (OSA) open-access journal Biomedical Optics Express.

Humans who overeat may develop the same neural patterns as drug addicts do
Eating for pleasure, rather than out of hunger, can prime our brain to want that hedonistic experience more and more.Humans who tend to overeat may develop the same patterns of neural activity in reward areas as drug addicts do; data suggest that eating high-sugar or high-fat diets can lead to cycles of craving and withdrawal.Although the concept of food addiction is controversial, lessons from recent research can put us on a fitter path. Regulating the amount of food choice we give ourselves, for example, and avoiding situations where we are conditioned to eat can help us consume less and feel better.
