The stromal vascular fraction: a regenerative reality?
In 2001, researchers discovered that fat tissue contains stem cells, which they termed adipose derived stem cells (ADSCs). To obtain these stem cells, fat tissue is taken from the abdomen of healthy adults undergoing liposuction and processed
Glaucoma: are people still going blind?
We have seen large advances in preventing, slowing down and reversing vision loss for patients with many eye diseases. Despite these advances, many people with eye disease end up losing their vision. What is the difference between
Are you eating genetically modified food?
There are some foods on the supermarket shelves now that are produced by a new food production, namely from a Genetically Modified Organism (GMO) or Genetically Engineered (GM). The GMO food products are basically altered from the
Diminished disease-free survival following lung cancer surgery
Treatment of lung cancer requires removal of a portion of a vital organ, which may reduce life expectancy. This would be acceptable when surgery prevents death from cancer. It is harmful in cases identified by screening in
Psychosocial dispair in adolescents with Diabetes Mellitus
Diabetes is among the diseases that cause high death rates and disability around the world. The most common complications of diabetes that lead to death and disability include heart diseases, neuron, kidney, eyes and foot ulcers diseases.
Neural Networks for identifying drunk persons using thermal infrared imagery
Neural networks were tested on infrared images of faces for discriminating intoxicated persons. Two different experimental approaches were thoroughly investigated. In the first one, each face was examined, location by location, in order to find out those
Where leprosy still lives
Leprosy affected 214,000-300,000 people per year globally between 2005 and 2014. It remains as a public health problem, particularly in the poorest communities of developing countries, such as India, Brazil and Indonesia. Globally, these three countries accounted
Out of thin air – how marine bacteria beat nitrogen limitation
Nitrogen (N), one of life’s most important building blocks, is often in short supply; both on land and in the ocean (Fig. 1). This shortage means that N is often the factor limiting the growth and abundance
Genetics and dietary stress explain low calcium absorption
It is well understood that osteoporosis is influenced by a variety of environmental factors such as age, nutrition, and race. Calcium absorption is one of these important factors and low levels of calcium absorption have been associated
Going my way? A tale of enzyme recruitment and activation
Protein synthesis is an energetically costly cellular process, in part due to the metabolic requirements of ribosome assembly and gene-specific messenger RNA (mRNA) production. Consequently, biosynthetic flux through the protein translation pathway is tightly regulated while translational
Specific danger signals associate with non-infection-related COPD exacerbations
Chronic Obstructive Pulmonary Disease (COPD) is a progressive and chronic lung disease, leading to difficulties with breathing for the patients. This is caused by the destruction of the lung sacs (alveoli), called emphysema and by inflammation of
Catalytic carbon-carbon bond formation
A chemical reaction is the transformation of one or more reagents into one or more products that takes place at a characteristic rate depending on the energy needed to activate the process. A catalyst is a substance
ATF3-dependent cross-talk between cardiomyocytes and macrophages promotes cardiac maladaptive remodeling
Cardiovascular diseases are disorders of the heart and blood vessels which are leading to heart failure. Cardiovascular diseases correspond to 30% of all deaths in the world. The molecular processes that undergone from a healthy heart to
Reversibility of FXTAS
Fragile X-associated tremor/ataxia syndrome or FXTAS is a relatively unknown neurodegenerative disorder characterized by progressive development of tremor, ataxia, parkinsonism, and psychiatric problems. The cause of the disease is a so-called premutation in the FMR1 gene, located
Lutetium-177 radioisotope targeted therapy for treatment of cancer and other diseases
By their nature, radioactive isotopes are unstable and can change to more stable forms by radioactive decay and emission of different types of radiation. This emitted radiation is useful for cancer treatment which includes placement of “sealed”
G protein signaling: a major culprit of essential hypertension
Blood pressure (BP) is the driving force that distributes the blood to the organs of the body according to their instantanous needs. It may be increased by pressor agents acting on the heart, vessels, and blood volume,
Cerium fluoride nanoparticles protect cells against oxidative stress
Nano-biomaterials engineering is one of today’s most promising areas of materials science. In very recent years, nanocrystalline cerium oxide (nanoceria) has been shown to possess enormous biological activity, which originates from its ability to scavenge the reactive
Species are always important
This review is based on the premise that all species are important to life on earth even if the exact role or value of a species has not been formally documented. Recently, many surprising and unexpected roles
