Simple blood test diagnoses Parkinson's disease long before symptoms appear
— 2 Dec 2011 10:20A new research report appearing in the December issue of the FASEB Journal (http://www.fasebj.org) shows how scientists from the United Kingdom have developed a simple blood test to detect Parkinson's disease even at the earliest stages. The test is possible because scientists found a substance in the blood, called 'phosphorylated alpha-synuclein,' which is common in people with Parkinson's disease, and then developed a way to identify its presence in our blood…
Early sign of Alzheimer's reversed in lab
— 2 Dec 2011 10:14One of the earliest known impairments caused by Alzheimer's disease - loss of sense of smell - can be restored by removing a plaque-forming protein in a mouse model of the disease, a study led by a Case Western Reserve University School of Medicine researcher finds…
Parental controls on embryonic development?
— 2 Dec 2011 10:11When a sperm fertilises an egg, each contributes a set of chromosomes to the resulting embryo, which at these very early stages is called a zygote. Early on, zygotic genes are inert, so embryonic development is largely controlled by parental factors. The activation of the zygotic genome therefore represents an important transition toward a more autonomous mode of embryonic development, and has been the subject of much speculation and scrutiny. Now, a new study published by Cell Press on December 1st in the journal Developmental Cell suggests that the reach of parental control in the embryo may be longer than we thought…
Newly discovered heart stem cells make muscle and bone
— 2 Dec 2011 10:08Researchers have identified a new and relatively abundant pool of stem cells in the heart. The findings in the December issue of Cell Stem Cell, a Cell Press publication, show that these heart cells have the capacity for long-term expansion and can form a variety of cell types, including muscle, bone, neural and heart cells…
BUSM researchers develop blood test to detect membranous nephropathy
— 2 Dec 2011 10:05Research conducted by a pair of physicians at Boston University School of Medicine (BUSM) and Boston Medical Centre (BMC) has led to the development of a test that can help diagnose membranous nephropathy in its early stages. The test, which is currently only offered in the research setting and is awaiting commercial development, could have significant implications in the diagnosis and treatment of the disease. Currently, the only way to diagnose the disease is through a biopsy…

Probiotics reduce infections for patients in intensive care
— 2 Dec 2011 09:56Traumatic brain injury is associated with a profound suppression of the patient's ability to fight infection. At the same time the patient also often suffers hyper-inflammation, due to the brain releasing glucocorticoids in response to the injury. New research published in BioMed Central's open access journal Critical Care shows that including probiotics with nutrients, supplied via the patient's feeding tube, increased interferon levels, reduced the number of infections, and even reduced the amount of time patients spent in intensive care…
High blood sugar levels in older women linked to colorectal cancer
— 2 Dec 2011 09:50Elevated blood sugar levels are associated with an increased risk of colorectal cancer, according to a study led by researchers at Albert Einstein College of Medicine of Yeshiva University. The findings, observed in nearly 5,000 postmenopausal women, appear in the Nov. 29 online edition of the British Journal of Cancer…
Engineered botulism toxins could have broader role in medicine
— 2 Dec 2011 09:44The most poisonous substance on Earth - already used medically in small doses to treat certain nerve disorders and facial wrinkles - could be re-engineered for an expanded role in helping millions of people with rheumatoid arthritis, asthma, psoriasis and other diseases, scientists are reporting. Their study appears in ACS' journal Biochemistry…
