Functional networks of the awake rabbit brain
The brain constantly transmits signals whether during idle wakefulness (i.e., “at rest”) or different behavioral states like cognitively-demanding tasks. Studies using functional magnetic resonance imaging (fMRI) in humans have consistently observed neural networks of coherent activity within
Understanding the rare disease alkaptonuria: the role of oxidative stress, inflammation and amyloidosis
一个lkaptonuria (AKU) is an ultra-rare disease that was recognized among the first inborn errors of metabolism. In AKU, an altered activity of the enzyme homogentisate 1,2-dioxygenase (HGD) occurring upon gene mutation lead to a defective metabolism of
The exploration of gene expression in Atlantic bluefin tuna
一个tlantic bluefin tuna (Thunus thynnus), the largest of the tuna species, is migratory top predator inhabiting the North Atlantic Ocean and the Mediterranean Sea. Extremely well adapted to life in open waters, they are able to traverse
Heavy metals and cyanobacteria: towards bioremediation
Heavy metals are one of the most common pollutants worldwide, being a serious hazard to the environment and public health. These metals are usually removed from polluted waters by physicochemical methods that can have substantial costs, low
Photometric patch electrode captures optical and electrical signals simultaneously in deep brain tissues
When neurons work they signal each other using action potentials, which is a rapid change of membrane potential and underlies the brain function. In most neurons action potentials accompany changes of intracellular concentration of calcium ions. Calcium
Is a tissue-engineering approach effective for the treatment of osteoporotic bone defects?
Osteoporosis (OP) is a disease that affects the formation, maintenance, and density of bone. OP is also associated with an increased risk of bone fracture. For those people/patients facing a traumatic injury or tumor removal in the
Preference for capretto and chevon depending on familiarity
The “capretto”, i.e. four to seven-week old kid fed on milk, is the traditional and, still, the main meat product in this class. It is a major component of farm income during the Easter and Christmas times.
Rising from obscurity: 11β-hydroxy-androstenedione under the spotlight
年代teroid hormones are small molecules that act as messengers in our bodies, regulating normal development and impacting on disease. These hormones are produced from cholesterol by the actions of enzymes− proteins which change cholesterol to form new
Immunochemical analysis of pesticides in strawberries
Broad retail of highly perishable fruits like strawberries requires application of agrochemicals at stages near the harvest, so significant amounts of pesticide residues are commonly found at the consumer level. Consequently, maximum residue limits (MRL) have been
