Change in gene may be underlying molecular defect in some colorectal cancers
Inactivation of a DNA repair gene may be an early step in the development of sporadic colorectal tumors, and detection of the molecular basis for this inactivation may ultimately be useful in risk assessment for colorectal cancer, according to a new study in the September 21 issue of the Cancers can arise from a region of cells with a "field...Underlying cause of massive pinyon pine die-off revealed
The high heat that accompanied the recent drought was the underlying cause of death for millions of pinyon pines throughout the Southwest, according to new research. The resulting landscape change will affect the ecosystem for decades. Hotter temperatures coupled with drought are the type of event predicted by global climate change models. The new finding suggests big, fast changes in ecos...New mechanism underlying pain found
Researchers at Johnson & Johnson Pharmaceutical Research & Development (J&JPRD) today announced that they have discovered a new molecular mechanism that may underlie neuropathic pain. The clearer understanding of the root-cause of chronic neuropathic pain, and the preclinical validation of new targets for pharmaceutical therapies shown in this research, together present an opportunity...Revealing the machinery underlying the 'plastic' juvenile brain
Among the central mysteries of neurobiology is what properties of the young brain enable it to so adeptly wire itself to adapt to experience—a quality known as plasticity. The extraordinary plasticity of the young brain occurs only during a narrow window of time known as the critical period. For example, children deprived of normal visual stimulation during an early critical period of the first f...Underlying relationship between Childhood insecurity and Eating Disorder
A novel study has shed light on a different dimension to eating disorder which seems to have its seeds sown during childhood. // Insecure feelings experienced during childhood and the formative years can lead to a negative perception of one’s body that can translate into an eating disorder in women, suggesting that the concept takes shape very early due to insecure attachment and separation anxie...Asthma –an underlying or associated cause of death
A recent research reveals that several older Australians could be dying due to respiratory diseases including asthma.// The Australian Institute of Health and Welfare conducted this study, according to which, some deaths and hospitalizations from asthma and chronic obstructive pulmonary disease (COPD) are not reported. Shortness of breath, wheezing, chest tightness and coughin...Hysteria Has Palpable Underlying Causes: Says Canadian Researchers
Patients who complain of symptoms of hysteria are often ticked off, by physicians, for having any discernable cause for their apparent ailment.// However, researchers from Sunnybrook Health Sciences Centre, disagree that it is merely a state of extreme emotions or emotional instability. Brain scans helped to detect evidence to prove evidence of dysfunction in brain tissue in three w...Evidence Underlying Repeated Courses of Steroids for Preterm Birth may Be Unsound
Scientists have warned that giving repeated courses of steroid drugs to mothers at risk of preterm delivery may be based on unsound evidence . Babies born before 32 weeks of pregnancy often have neonatal lung disease, a major cause of illness and death. Several previous analyses concluded that steroids were most effective when given within a week of delivery, which le...Understanding the Mechanism Underlying Embryo Development
Research aimed at understanding the mechanisms underlying embryo development has taken a step forward thanks to collaborative work between biologists specialized in the study of the fruit fly (Drosophila melanogaster) and scientists specialized in the design of mathematical models that simulate the functioning of biological systems. Specifically, a study of wing formation in Drosophil...
