Spinal cord injury: Human cells derived from stem cells restore movement in animal models

Spinal cord injury: Human cells derived from stem cells restore movement in animal models

ScienceDaily (Mar. 3, 2011) — For the first time, scientists discovered that a specific type of human cell, generated from stem cells and transplanted into spinal cord injured rats, provide tremendous benefit, not only repairing damage to the nervous system but helping the animals regain locomotor function as well. The study, published March 2 in the journal PLoS ONE , focuses on human astrocytes — the major support cells in the central nervous system — and indicates that transplantation of these cells represents a potential new avenue for the treatment of spinal cord injuries and other central nervous system disorders.

MRIs reveal signs of brain injuries not seen in CT scans

Dec. 18, 2012 — Hospital MRIs may be better at predicting long-term outcomes for people with mild traumatic brain injuries than CT scans, the standard technique for evaluating such injuries in the emergency room, according to a clinical trial led by researchers at the University of California, San Francisco (UCSF) and the San Francisco General Hospital and Trauma Center (SFGH) Continue reading

New ‘pipeline’ device offers new option for difficult-to-treat aneurysms, study suggests

ScienceDaily (Dec. 3, 2012) — A new technology called the Pipeline embolization device (PED) shows encouraging results in patients with certain types of difficult-to-treat brain aneurysms, reports the December issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. Data collected since the PED was approved for marketing show generally good results in “real world” clinical practice. Continue reading

Repeated surgeries appear to extend life of patients with deadliest of brain cancers

Repeated surgeries appear to extend life of patients with deadliest of brain cancers

ScienceDaily (Nov. 1, 2012) — People who undergo repeated surgeries to remove glioblastomas — the most aggressive and deadliest type of brain tumors — may survive longer than those who have just a one-time operation, new Johns Hopkins research suggests Continue reading

New study sheds light on bone marrow stem cell therapy for pancreatic recovery

ScienceDaily (Oct. 2, 2012) — Researchers at Cedars-Sinai’s Maxine Dunitz Neurosurgical Institute have found that a blood vessel-building gene boosts the ability of human bone marrow stem cells to sustain pancreatic recovery in a laboratory mouse model of insulin-dependent diabetes.

Breakthrough on immune system and brain tumors

Breakthrough on immune system and brain tumors

ScienceDaily (Sep. 26, 2012) — In what could be a breakthrough in the treatment of deadly brain tumors, a team of researchers from Barrow Neurological Institute and Arizona State University has discovered that the immune system reacts differently to different types of brain tissue, shedding light on why cancerous brain tumors are so difficult to treat. The large, two-part study, led by Barrow research fellow Sergiy Kushchayev, MD under the guidance of Dr Continue reading

Chronic stress linked to high risk of stroke

Chronic stress linked to high risk of stroke

ScienceDaily (Aug. 29, 2012) — Chronic stress, prompted by major life stressors and type A personality traits, is linked to a high risk of stroke, finds research published online in the Journal of Neurology Neurosurgery and Psychiatry . Chronic stress, manifested as physical and/or mental symptoms in response to stressors lasting longer than 6 months has been linked to a heightened risk of heart disease. Continue reading
