La Ansiedad, los Peptidos Opioides y la Nutrición ¿Como se relacionan? Dr. Julio Salazar Gonzales.
La Dra. Brigitte Kieffer neurobióloga de la Universidad Louis Pasteur nos detalla que en el año 1.973 se descubrió que la morfina así como la heroína calzaban muy bien con algunos receptores cerebrales y pronto se concluyo que, obviamente si existen sustancias exógenas que los activan, también deberían de existir sustancias endógenas que los estimulen de la misma manera. A partir de estas conclusiones se pusieron a buscar las sustancias que de manera endógena calzaban en los receptores Opioides. Es decir ubicar las sustancias que tienen estos efectos en el cerebro. Las investigaciones derivadas de este principio concluyeron cuando se descubrió la sustancia, que son pequeñas proteínas a los cuales se les denomino péptidos Opioides. Estos péptidos Opioides al igual que sus receptores son sustancias endógenas; es decir fabricadas por nuestro organismo. Estos Péptidos Opioides son poli péptidos pertenecientes al grupo de los compuestos neuropéptidos. Al igual que otros agentes afines,

One in six American children now has a developmental disability — a 17% increase over the past decade, driven largely by increases in autism and attention deficit hyperactivity disorder (ADHD)according to government researchers.
The new study, published in Pediatrics, found that 15% of U.S. children aged 3 to 17 were diagnosed with a developmental disability in 2006-08 — about 10 million children in all. In 1997-99, that rate was 12.8%, or 8 million children.
While researchers saw increases in a wide range of developmental problems, including stuttering and learning disabilities, the most significant increases were seen with autism and ADHD. Autism rates nearly quadrupled over the study period, from 0.19% of children in 1997-99 to 0.74% in 2006-08. But, overall, ADHD accounted for the greatest number of developmental disability cases; rates rose by 33%, from 5.7% of children in 1997-99 to 7.6% by 2008.
Nearly twice as many boys as girls had a disability. ... This might be because some genetic disabilities are more likely to be inherited by males, although it could also be that the symptoms of ADHD and other disabilities are more obvious in boys, and are therefore more likely to be diagnosed, the study notes.
Rates were also substantially higher than average among children from low-income families and children on Medicaid. Hispanic children had lower rates of disabilities than white or black children, which perhaps reflects language difficulties and other barriers to accessing health services rather than the true rate of disability.
The Centers for Disease Control and Prevention (CDC) study was based on data from the National Health Interview Surveys, which included in-person
