The interest in the biological effects of non-ionizing Electro Magnetic Fields (EMFs) and Static Magnetic Fields (SMFs) on the whole organism, as well on cellular systems, has noticeably increased in recent years in consideration of their increased production (from the generation and transmission of electricity, to domestic appliances and industrial equipment, to telecommunications and broadcasting) and the possible health risk for humans. About one century ago, associated with the wide use...

Therapeutic lentiviral vectors are emerging as vital tools for molecular medicine as evidenced by the growing number of clinical trials using these vector systems. From a basic research standpoint, lentiviral vectors are very intriguing substrates. On the one hand, the HIV-1 genome offers expanded cloning capacity and the capability to transduce nondividing cells such as hematopoietic stem cells (HSCs) and neurons. However, concerns associated with the potential risk of generating...

Formation of new blood vessels, also known as angiogenesis, is crucial for sustained tumor growth and cancer metastasis. Recently, clinically available therapies to suppress the growth of these vessels have been available to improve patient survival in some cancer types. Accurate detection and quantification of blood vessel growth using nonsurgical methods would greatly complement current therapies and allow physicians to quickly assess treatment regimens and adjust them as necessary. In the...

Pulmonary arterial hypertension (PAH) is a progressive disease, marked by shortness of breath and fatigue which can be fatal if untreated. Increased pressure in the pulmonary artery and its branches is associated with dysfunctional growth control of endothelial and smooth muscle cells leading to excessive thickening of the blood vessel wall, obliteration of the lumen and right heart failure. BMP (bone morphogenetic protein) receptors play an important role in preventing excess growth of...

Researchers at the Tulane University School of Medicine, in New Orleans, LA, have demonstrated that thymoquinone (TQ) a major component of black seed oil (Nigella sativa) can suppress the growth of several aggressive prostate cancer (PCa) cell lines, in vitro. Although previous studies have shown the anti-proliferative effects of TQ in different types of cancers, the molecular mechanism of this effect of TQ had not been delineated. Since TQ has a structure similar to ubiquinone, a component...

Research sheds light on early embryogenesis, genetic disease Chromosome 22q11 deletion syndrome (also known as DiGeorge syndrome) is the most common human chromosome deletion syndrome, having an estimated incidence of at least one in 4,000 live births. It has a range of severity but a multisystem impact, with symptoms that may include congenital heart defects, immunologic and endocrine abnormalities, cleft palate, gastrointestinal problems, and neuropsychiatric abnormalities. Nearly...

Phenytoin is a well known antiepileptic agent widely used throughout the world. Recent clinical studies in patients with bipolar disorder have suggested that, as for other anticonvulsant drugs commonly used in the treatment of bipolar patients including valproate and carbamazepine, phenytoin may have mood-stabilizing effects in addition to its well-known anticonvulsant properties. In a study published in the March 2010 issue of Experimental Biology and Medicine Veronica Mariotti and...

Researchers at the Pontifícia Universidade Cat³lica do Paraná and Instituto Carlos Chagas have evaluated the therapeutic potential of purified and expanded CD133+ cells human umbilical cord blood (HUCB)-derived in treating myocardial infarction by intramyocardially injecting them into a rat model. Patients who have high cardiovascular risks have fewer endothelial progenitor cells (EPCs) and their EPCs exhibit greater in vitro senescence. HUCB-derived EPCs could be...

Two indicators of liver function,  glutamyl transferase (GGT) and albumin (ALB) have been implicated in the pathogenesis of atherosclerosis. It is known that the variation in the plasma level of these liver related proteins is genetically influenced. The purpose of this study published in the December 2009 issue of Experimental Biology and Medicine was to identify chromosomal regions containing genes that affect the variation in the plasma levels of GGT and...

As part of an effort to develop effective medical therapies that block the progression of liver cyst growth in patients with Autosomal Dominant Polycystic Kidney Disease (ADPKD), researchers at the University of Colorado Anschutz Medical Center have found that the liver cyst walls develop and maintain a vasculature as they grow out from the body of the liver and that factors released by epithelial cells that line the liver cyst wall lumen can drive the proliferation and development of...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
