Development of novel therapies for endothelial damage may heal atherosclerotic plaques
2013-04-21
(Press-News.org) BOSTON — Heart disease and approximately half of all strokes are the results of advanced atherosclerosis with damaged endothelium, the inner lining of blood vessels. In 2009, the direct and indirect annual cost of heart disease and stroke was approximately $312.6 billion. Projections are for the total cost of heart disease to increase from $523 to $1.126 billion from 2013 to 2030. And by 2030, it is expected that there will be more than 148 million of the US population would have heart disease. Development of new technologies for assessing and treating endothelium damage will help reduce that financial burden as reduce the human health burden resulting from atherosclerosis.
Dr. Hua Pan, Research Instructor in Medicine at Dr. Samuel Wickline's Laboratory in Washington University School of Medicine, investigated quantitative evaluation and developed novel therapies for endothelial barrier damage. The evolution and severity of endothelium damage in advanced atherosclerotic plaque remain unknown, in part because quantifiable methods are lacking for its in vivo assessment. Her latest study is the first to demonstrate, in a well-established atherosclerosis mouse model, ApoE deficient mice, a multifunctional perfluorocarbon (PFC) nanoparticle (NP) for quantification of endothelial damage as well as targeted anti-inflammatory drug delivery to the endothelium damage site.
The study, conducted in ApoE deficient mice, quantified endothelium damage by using PFC NP retained in mouse aorta as surrogate. It demonstrated the evolution and severity of endothelium damage in correlation to the length of the animal fat-diet consumption. Moreover, the same PFC NP loaded with anti-inflammatory drug, NF-κB inhibitor, down-regulated inflammation. Dr. Wickline noted, this finding provided a new avenue for defining disease stage and for following therapy to heal dangerous atherosclerotic plaques.
Her findings will be presented April 22, 2013 during Experimental Biology 2013 in Boston, MA.

BOSTON — Stress triggered neuropsychiatric disorders take an enormous personal, social and economic toll on society. In the US more than half of adults are exposed to at least one traumatic event throughout their lives. Post-traumatic stress disorder (PTSD) is a debilitating anxiety disorder associated with exposure to a traumatic event outside the range of normal human experience. PTSD typically follows a chronic, often lifelong, course. Patients have diminished quality of life, are more likely to manifest other psychiatric disorders such as depression and six times more ...

BOSTON — More than 1 in 270 people in the US are living with HIV and every 9.5 minutes someone is else is infected. The economic cost estimates associated with HIV/AIDS exceed 36 billion dollars a year. The development of effective drug treatments have allowed people with HIV to live longer with federal health officials now predicting that by 2015 one-half of the population with HIV in the US will be older than 50.

BOSTON — Depression is the leading cause of disability with more than 350 million people globally affected by this disease. In addition to debilitating consequences on mental health, depression predisposes an individual to physiological disease such as heart disease, and conversely heart disease increases the risk of depression. According to the World Health Organization by the year 2020 heart disease and depression will be the number one and number two leading causes of disability in developed countries. While the co-occurrence of these disorders is well recognized, an ...

Geneva, Switzerland: Unavoidable damage caused to the heart and lungs by radiotherapy treatment of tumours in the chest region can be limited by the administration of an ACE inhibitor, a drug commonly used in the treatment of cardiovascular disease, a group of Dutch researchers have found. [1]
Common cancers such as breast, oesophagus, lung, and Hodgkin's lymphoma are frequently treated with radiotherapy, but the radiation dose that can be given safely is limited by the sensitivity of the health lung tissue which is also irradiated.
The lung is a particularly complex ...

Geneva, Switzerland: Intensity modulated radiotherapy (IMRT) gives better results than standard radiotherapy in patients with early breast cancer, according to results from a randomised trial presented today (Sunday) to the 2nd Forum of the European Society for Radiotherapy and Oncology (ESTRO). IMRT is an advanced, high-precision form of radiotherapy that can deliver an even dose of radiation, thus reducing the cosmetic problems that can often occur after breast radiotherapy.
"We believe that this study, the largest prospective trial in the world to test breast IMRT ...
