Platelets promote the liver's regeneration process following surgery Certain platelet-derived growth factors are of major significance for the liver's regeneration processes. It has been shown that platelets can encourage the regrowth of liver tissue in patients who have had parts of their liver removed surgically. This may also act as a starting point for the prediction of potential postoperative problems.

Electric fields remove nanoparticles from blood with ease A new technology that uses an oscillating electric field to easily and quickly isolate drug-delivery nanoparticles from blood has been developed by a team of engineers. The technology could serve as a general tool to separate and recover nanoparticles from other complex fluids for medical, environmental, and industrial applications

The complex sneeze, caught on tape From the daintiest sleeve-stifled 'shoo to the mightiest head-whipping howl, a sneeze is as unique to an individual as a laugh -- we all do it, but everyone seems to do it differently. We know that sneezes can spread infectious diseases like measles, influenza or SARS, suspending viruses in droplets that may be inhaled or deposited onto surfaces and later picked up on the hands of some unsuspecting passerby. But we don't understand exactly how far a sneeze can spread or if and why some people spread sickness through sneezing more effectively than others.

Health Research: Accelerated brain aging in type 1 diabetes ♦ The dark side of cannabis: Panic attacks, nausea ♦ New leads into nerve regeneration

Accelerated brain aging in type 1 diabetes related to cognitive complications The brains of people with type 1 diabetes show signs of accelerated aging that correlate with slower information processing, according to research. The findings indicate that clinicians should consider screening middle-aged patients with type 1 diabetes for cognitive difficulties. If progressive, these changes could influence their ability to manage their diabetes.

The dark side of cannabis: Panic attacks, nausea

Although the use of cannabis as a medical drug is currently booming, we should not forget that leisure time consumption -- for example, smoking weed -- can cause acute and chronic harms. These include panic attacks, impaired coordination of movement, and nausea.

Proteomics provides new leads into nerve regeneration Using proteomics techniques to study injured optic nerves, researchers have identified previously unrecognized proteins and pathways involved in nerve regeneration. Adding back one of these proteins -- the oncogene c-myc -- they achieved unprecedented optic nerve regeneration in mice when combined with two other known strategies.

Profiling approach to enable right lung cancer treatment match A new way to genetically profile lung cancer samples has been developed by researchers, potentially allowing doctors to more easily identify the most appropriate treatment for patients.
Breast cancer vaccines may work better with silicon microparticles The effectiveness of cancer vaccines could be dramatically boosted by first loading the cancer antigens into silicon microparticles, report scientists. Model studies showed that microparticles loaded with an antigen, HER2, not only protected the antigen from premature destruction, but also stimulated the immune system to recognize and relentlessly attack cancer cells overexpressing the HER2 antigen.

Cardiovascular Research: Digoxin increases the risk of early death ♦ Bystander CPR helps cardiac arrest survivors ♦ Foundations of heart regeneration uncovered

Frailty among older heart patients helps predict severe outcomes Frailty among older people with cardiovascular disease appears to be more predictive than age for gauging their risk of heart attack, stroke and death.

How oxidizing a heart 'brake” causes heart damage Oxidative stress has been long known to fuel disease, but how exactly it damages various organs has been challenging to sort out. Now scientists say research in mice reveals why oxidation comes to be so corrosive to heart muscle.

Digoxin increases the risk of early death in patients with heart problems There is conflicting evidence about whether digoxin, a drug that has been used worldwide for centuries to treat heart disease, might contribute to an increase in deaths in patients with atrial fibrillation or congestive heart failure. The evidence to date shows that it is associated with an increased risk of death

Bystander CPR helps cardiac arrest survivors return to work In Denmark, more bystanders performing CPR contributed to more cardiac arrest survivors returning to work, Cardiac arrest is the abrupt loss of heart function in a person who may or may not have diagnosed heart disease. The time and mode of death are unexpected. It occurs instantly or shortly after symptoms appear.

Foundations of heart regeneration uncovered: Outer layer of heart must be healed first Medical researchers have found that a key to the zebra fish's ability to regenerate cardiac tissue lies in the outer layer of the heart known as the epicardium. When this critical layer is damaged, the whole repair process is delayed as the epicardium undergoes a round of self-healing before tending to the rest of the heart. The finding points to a possible target for repairing the damage caused by a heart attack.

Health Research: Deadly fungus evades the immune system ♦ Why skin is resistant to tearing ♦ Bionic hand, powered by his thoughts

How a deadly fungus evades the immune system New research has scientists rethinking how a lethal fungus grows and kills immune cells. The study hints at a new approach to therapy for Candida albicans, one of the most common causes of bloodstream infections.

Protein may improve liver regeneration: GF21 boosts regenerative ability in mice carrying human PPAR alpha protein Researchers have illuminated an important distinction between mice and humans: how human livers heal. The difference centers on a protein called PPAR alpha which activates liver regeneration.

Skin tough: Why skin is resistant to tearing Researchers have recorded the first direct observations of the micro-scale mechanisms behind the ability of skin to resist tearing. The results could be applied to the improvement of artificial skin, or to the development of thin film polymers for flexible electronics.

Non-invasive technique allows amputee to use bionic hand, powered by his thoughts Medical researchers have created an algorithm that allowed a man to grasp a bottle and other objects with a prosthetic hand, powered only by his thoughts.

Intestinal bacteria can be used to classify effects of different diseases It is possible to quantify and classify the effects of different diseases on the activity of intestinal bacteria, new research demonstrates for the first time. Human intestinal flora, known as microbiota, can be considered as an additional organ in the body. It consists of millions of bacteria that interact with each other and with the body, thus affecting its functioning and health. It is known that many intestinal disorders such as Crohn's disease and ulcerative colitis, and diseases such as obesity, cancer and autoimmune diseases can cause changes in the composition of gut bacteria.

Health News: injured kidneys can be used for transplants ♦ Alternative way to pay for expensive drugs ♦ Injured spinal cord: Regeneration possible ♦ Epilepsy

Even injured kidneys can be used for transplants,  Kidneys from deceased donors that have acute injuries are frequently discarded instead of being used for transplant. However, a study finds that such kidneys may be more viable than previously thought, and should be considered to meet the growing demand for organ transplants. Continue Reading

Alternative way to pay for expensive drugs may be needed  A major challenge facing the world's health care systems is paying for a new breed of expensive breakthrough drugs. One way to address the issue is to approach it the same way as other industries where suppliers encourage investment through approaches such as equipment leases or supplier-financed credit. Continue Reading

Gene linked with early epilepsy discovered  Certain types of early-onset epilepsy are caused by previously unknown mutations of a potassium channel gene, KCNA2. The mutations disrupt the electrical balance in the brain in two ways. In some patients, the flow of potassium is greatly reduced; while in others, it is raised enormously. Both states can lead to hard-to-treat epileptic seizures. New information may lead .Continue Reading

Injured spinal cord: Regeneration possible with epothilon  Damage to the spinal cord rarely heals because the injured nerve cells fail to regenerate. The regrowth of their long nerve fibers is hindered by scar tissue and molecular processes inside the nerves. Scientists in now report that help might be on the way from an unexpected quarter Continue Reading:
