Lymphocytes are immune system cells devoted to the defence against enemies coming from both outside (i.e. bacteria and viruses) and inside (tumours). Several times per day these cells escape from the blood and enter into the immune
Cardiovascular diseases are among the top causes of mortality in the world. Huge efforts are made to fight against the cardiovascular diseases. However, the variability of the symptoms and risk factors makes this fight very challenging. While
Brought on by rapid economic growth and urbanization, overweight, obesity and related diseases reached dramatic levels in the developing world, particularly among emerging countries such as Mexico. More than 2/3 of Mexicans are overweight and almost 1/3
Heme is a complex containing iron and protoporphyrin IX and it is commonly bound to proteins involved in oxygen transport, detoxification and energy production. However, this molecule has been known to have toxic effects in the heart.
Measuring the arterial oxygen content (saturation) of the blood is easily done by pulse oximetry. In newborn infants a probe emitting and absorbing light is put on the hand or foot (or booth) and a reliable result
Regucalcin (RGN) is a protein with a multifunctional role, which regulates the basic biological processes determining cell fate. RGN actions have been implicated in the control of intracellular calcium levels, oxidative stress, cell metabolism, cell death and
Table olive is one of the most important products in the world, with a total production of 2,512,500 tons in the 2012/2013. Different processing methods are applied for producing table olives with the objective of eliminating their
The increasing prevalence of inflammatory diseases worldwide underlines the importance to study the molecular mechanisms leading to these disorders. Recent genome-wide association studies based on large group of patients and healthy controls revealed candidate genes, which are
Epidermis of insects are covered with sensilla (sensory receptors) and exocrine glands, which are responsible for sensing and interacting with the external environment. Exocrine glands secret chemicals, such as pheromones, lubricant and noxious substances, to the outside
Save your pancreas from diabetes! Your beta cell reserve is critical for prevention and treatment of diabetes.
To date the number of people with diabetes is estimated to be 387 million over the world. This number is continuing to increase and predicted to be 592 million in 2035. Despite the recent advance in the
For our future sustainable society mankind will have to make efficient use of solar energy. The conversion of sunlight to electricity is already a powerful technology, but for storage and transport we need liquid fuels, which have
Sewage treatment is the process that converts wastewaters (water no longer suitable for other purposes) into a clean effluent that can be reused. The treatment process consists into removing impurities (such as organic matter, pathogens, heavy metals
Imagine a world where one size does not fit all, wait that’s the world we live in now. So why is the treatment you get under the “one size fits all” umbrella, we are all different, right?
Coronary artery disease refers to narrowing of the arteries that supply blood to the heart. Lack of blood supply to the heart can result in a myocardial infarction, commonly referred to as a heart attack. One way
Environmental factors such as light, temperature, water and gravity have major effects on plant development. In addition, hormones within the plant bring about developmental changes during the plant life cycle. Extensive crosstalk exists between environmental and hormone
The ancient way of curing disease was the administration of natural products to the patient. The next step in drug discovery resulted from advances in chemistry. After isolation of natural active ingredients, synthesis in the laboratory of
Among the things we experience in daily life, nothing appears to be simpler than perceiving the sizes of visual objects. “A large object occupies a large surface area on the retina and looks large. That’s it.”. However,
