Most effective saliva biomarkers for the early detection of oral
Oral, head and neck cancer ranks sixth in the most common types of cancer around the world and accounts for 6% of all tumors. The majority of these neoplastic processes are squamous cell carcinomas that develop in the upper part of the throat as a result of exposure to different risk factors.
The urinary density: a useful test in children
The Urine density is a test of concentration and dilution of the kidney; it reflects the weight of the solutes in the urine measured through a refractometer. Any alteration that occurs in the urinary density is associated with damage in the concentration function of the renal tubule; its value varies throughout the day oscillating between 1,003-1,030 g/l, being higher than 1,020 in the morning due to the restriction of liquids during the night. Newborns and infants can have a urinary density between 1,005-1,010 g/l and older children 1,010-1,025 g/l.
Cerebro masculino y femenino, ¿Por qué son distintos?
Pocas cosas pueden ser tan polémicas y estar tan trufadas de tópicos, prejuicios y sexismo como una conversación sobre las diferencias entre el cerebro masculino y el femenino. Muchos estudios que llegan a conclusiones como que ellas son mejores haciendo varias cosas a la vez (lo que se conoce como multitarea) o que ellos son imbatibles leyendo mapas se basan en una pequeña muestra, en la que puede influir el azar.
How big data is redefining biotechnology?
As interesting as big data can be in Silicon Valley, its most fascinating applications often happen elsewhere. Machine learning and artificial intelligence are all the rage today in venture capital circles. We’ve seen spectacular exits in the past few years, from Google absorbing Deepmind in 2014 for $500 million, to Twitter buying TellApart in 2015 for $533 million, and Intel swallowing Nervana in 2016 for $400 million. But these were all IT plays.
un ver marin aux pouvoirs miraculeux pour la médecine
Un ver dont l’hémoglobine – molécule présente dans les globules rouges et qui a pour rôle de transporter l’oxygène dans le corps – est capable d’acheminer cinquante fois plus d’oxygène que l’hémoglobine humaine. Contrairement à cette dernière, enfermée dans des globules rouges, celle de l’arénicole est extracellulaire.
The Threat Of These Times: Bacterial Resistance (Br)
It refers to the resistance of these microorganisms to an antimicrobial to which they were originally vulnerable, which has as a main consequence that many treatments are ineffective when administered to patients. It can be said that this phenomenon is today one of the greatest threats to global health, food security and the development of society.
A project beyond life
“From death comes life,” said researchers who studied how decomposing bodies, with the help of scavengers, might alter plant diversity across a broad landscape.
Mujer que descubre y lucha contra el VIH/SIDA
Inicio de los años ochenta del siglo XX. Realmente, no hace tantos años. Los médicos de Europa y Estados Unidos comienzan a documentar extraños casos de una rara neumonía y de sarcoma de Kaposi en jóvenes hasta entonces sanos. Se encienden las alarmas.
Palais de découverte présente des salles de chimie
La salle Air liquide vous accueille avec une nouvelle muséographie. Cette rénovation réalisée avec notre partenaire, la société Air liquide, expose de nouveaux supports visuels qui permettent de comprendre comment l’air à l’état liquide est obtenu au Palais de la découverte.
¡The funny side of science!
Time to get messy, light some stuff on fire, and use food products in ways they were never intended! Parents and teachers across the internet have found fun to teach kids science, and have documented the experiments for the rest of us. Here are 15 hands-on science lessons that will stick in a kid’s brain for longer than anything they get from a textbook.
