Elevated protein levels in cardiac muscles could predict mortality following angioplasty
New research shows that elevated levels of cardiac troponin T (cTnT) or I (cTnI) in patients who had angioplasty indicate a higher risk of all-cause mortality and long-term adverse events such as heart attack. Routine monitoring of these protein levels following nonemergent percutaneous coronary intervention (PCI) could improve long-term outcomes for these patients. Details of the analysis are available online in Catheterization and Cardiovascular Interventions, a peer-reviewed journal of The Society for Cardiovascular Angiography and Interventions (SCAI).
Stem cells from bone marrow save the day

Chiropractic manipulation results in little or no risk of chest injury
Dynamic chest compression occurs during spinal manipulation. While dynamic chest compression has been well studied in events such as motor vehicle collisions, chest compression forces have not been studied during chiropractic manipulation. In a study published online today in the Journal of Manipulative and Physiological Therapeutics, researchers quantified and analyzed the magnitude of chest compressions during typical as well as maximum chiropractic manipulation and have found them to be well under the threshold for injury.

The study is available online in Cell on May 12, and will appear in the May 27 print edition.

Do you fear…Now that Friday the 13th is here?
(Medical Xpress) -- Have you watched the movie Friday the 13th? Scary, isn’t it? Well, perhaps not quite as scary as the infamous Rebecca Black song, “Friday” – but close enough. If you are one of those who carries around a rabbit’s foot and strokes it all day long for good luck or makes a wish after blowing away a fallen eyelash – then you are probably in the midst of bolting your doors, turning on all the lights and hiding under the comforting warmth of your comforter. Tomorrow just so happens to be Friday the 13th and if you have friggatriskaidekaphobia – it’s simply not a day to be trifled with.

All of the tissues and organs of the body arise from one of three embryonic precursors: the ectoderm, mesoderm and endoderm. The ectoderm contributes to several tissues, including the nervous system and the skin, but some studies have suggested that development into neurons requires nothing more than the absence of specific inhibitory signals.

Findings could lead to a blood test for lung cancer
Researchers have identified characteristic patterns of molecules called microRNA (miRNA) in the blood of people with lung cancer that might reveal both the presence and aggressiveness of the disease, and perhaps who is at risk of developing it. These patterns may be detectable up to two years before the tumor is found by computed tomography (CT) scans.
Research breakthrough on male infertility

Artificial grammar learning reveals inborn language sense, study shows
Parents know the unparalleled joy and wonder of hearing a beloved child's first words turn quickly into whole sentences and then babbling paragraphs. But how human children acquire language-which is so complex and has so many variations-remains largely a mystery. Fifty years ago, linguist and philosopher Noam Chomsky proposed an answer: Humans are able to learn language so quickly because some knowledge of grammar is hardwired into our brains. In other words, we know some of the most fundamental things about human language unconsciously at birth, without ever being taught.
New test may help distinguish between vegetative and minimally conscious state
(PhysOrg.com) -- In a new study published in Science, researchers from the University of Liege in Belgium, led by Dr. Melanie Boly, share the discovery of a new test that could aid physicians in differentiating between vegetative and minimally conscious states in patients with brain damage.

Alzheimer's risk gene disrupts brain's wiring 50 years before disease hits
What if you were told you carried a gene that increases your risk for Alzheimer's disease? And what if you were told this gene starts to do its damage not when you're old but when you're young?
As time goes by, it gets tougher to 'just remember this'
The older we get, the more difficulty we seem to have remembering things. We reassure ourselves that our brains' "hard drives" are too full to handle the new information that comes in daily. But a Johns Hopkins neuroscientist suggests that our aging brains are unable to process this information as "new" because the brain pathways leading to the hippocampus become degraded over time. As a result, our brains cannot accurately "file" new information.

(PhysOrg.com) -- Contrary to what most people may think, the speciation rates of plants are not linked to the first development of a novel physical trait or mechanism. New international research shows that plants fiddle around with their performance and configuration before setting out to create better versions of themselves. The findings are presented in the journal American Journal of Botany.

Same fungus, different strains
Fungi play key roles in nature and are valued for their great importance in industry. Consider citric acid, a key additive in several foods and pharmaceuticals produced on a large-scale basis for decades with the help of the filamentous fungus Aspergillus niger. While A. niger is an integral player in the carbon cycle, it possesses an arsenal of enzymes that can be deployed in breaking down plant cell walls to free up sugars that can then be fermented and distilled into biofuel, a process being optimized by U.S. Department of Energy researchers.
Study finds therapies using induced pluripotent stem cells could encounter immune rejection problems
Biologists at UC San Diego have discovered that an important class of stem cells known as "induced pluripotent stem cells," or iPSCs, derived from an individual's own cells, could face immune rejection problems if they are used in future stem cell therapies.
