High blood pressure in midlife is linked to increased brain damage in later life
Higher than normal blood pressure is linked to more extensive brain damage in the elderly, according to a new study published today in the European Heart Journal. In particular, the study found that there was a strong association between diastolic blood pressure (the blood pressure between heart beats) before the age of 50 and brain damage in later life, even if the diastolic blood pressure was within what is normally considered to be a healthy range.

A bypass route for the coronary vessels in the heart?
When the heart develops, some of its coronary blood vessels develop from cells lining the inner surface of the heart's ventricular chambers (endocardium). Novel findings suggest that new blood vessel growth in the heart can be stimulated with the VEGF-B growth factor from the same source after myocardial infarction to increase blood delivery to the damaged area.

Reversal of glial scar tissue back to neuronal tissue through neuroregenerative gene therapy
Brain or spinal cord injury often results in glial scar tissue that is correlated to neural functional loss. Glial scar is a well-known obstacle for neural regeneration. A research team led by Prof. Gong Chen at Jinan University, Guangzhou, published an article in the current issue of Frontiers in Cellular Neuroscience, demonstrating that glial scar tissue can be reversed back to neuronal tissue through NeuroD1-based neuroregenerative gene therapy.

Cancer metastasis: From problem to opportunity
When cancer metastasizes, it often ends up in the lungs, where the new tumors unleash a cascade of chemical cues that thwart the body's immune response. A team of researchers from the Wyss Institute has created a new approach that attacks metastasis itself by using red blood cells as couriers to deliver nanoparticles filled with immune-cell-attracting chemicals. This approach halted lung tumor growth in mice with metastatic breast cancer and protected the animals against future cancer recurrences.  (2020-11-16)

Diet affects skin gene expression in both healthy and atopic dogs
Differences in skin gene expression were observed between healthy and atopic Staffordshire Bull Terriers as well as between dogs that ate either dry food or raw food.

New screening questionnaire can identify people at high risk of developing heart disease
A new study in a Swedish population of middle-aged adults found that four out of 10 people have atherosclerosis, a buildup of fatty deposits that reduce blood flow to the heart. Early detection of coronary artery disease is needed in order to provide preventive treatment and decrease the risk of heart attack. Researchers developed a personalized screening strategy to identify individuals with a higher probability of developing cardiovascular disease. (2020-11-13)

Tracking down the causes of heart attack
Heart attacks strike suddenly and have a range of different triggers. Researchers from Charité - Universitätsmedizin Berlin and the German Centre for Cardiovascular Research (DZHK) were able to uncover a further underlying cause. Studying arterial deposits (plaque) in patients with acute coronary syndrome, the researchers found that, in some patients, these were characterized by activated immune cells which, as a result of altered flow conditions within the vessel, had accumulated on the interior arterial wall, causing damage to the arterial lining.

Unraveling the genetic determinants of small vessel vasculitis
Researchers from the University of Tsukuba have shown that the single-nucleotide variants of TERT and DSP, which promote risk for idiopathic pulmonary fibrosis (IPF), are significantly associated with susceptibility to microscopic polyangiitis and myeloperoxidase-ANCA associated vasculitis. Interestingly, there was no clear link to the severe complication interstitial lung disease (ILD). These findings suggest a shared genetic susceptibility between IPF and ANCA-associated vasculitides that may be independent of ILD risk. (2020-11-03)

New research shows SARS-CoV-2 spike proteins disrupt the blood-brain barrier
New work by scientists at the Lewis Katz School of Medicine at Temple University shows that the spike proteins that extrude from SARS-CoV-2 promote inflammatory responses on the endothelial cells that form the blood-brain barrier. The study, published in the December print issue of the journal Neurobiology of Disease, is the first to show that SARS-CoV-2 spike proteins can cause this barrier to become ''leaky,'' potentially disrupting the delicate neural networks within the brain.

A patch that could help heal broken hearts
According to the American Heart Association, heart disease is the leading cause of death worldwide in recent years. During a heart attack, or myocardial infarction (MI), a blocked artery and the resulting oxygen deprivation cause massive cardiac cell death, blood vessel impairment and inflammation. Now, researchers reporting in ACS Biomaterials Science & Engineering have developed a cardiac patch with tiny engineered blood vessels that improved recovery from MI in rats and pigs. (2020-10-28)
