Curcumin

Lovers of Indian food, give yourselves a second helping: Daily consumption of a certain form of curcumin — the substance that gives Indian curry its bright color — improved memory and mood in people with mild, age-related memory loss, according to the results of a study conducted by UCLA researchers.
The research is in American Journal of Geriatric Psychiatry. (full open access)

Emotion and Memory



Neuroscientists have charted the incoming and outgoing connections of a brain region located deep within the primate prefrontal cortex that has important roles in emotion and memory processes.

Saúde do Idoso

Saúde do Idoso 1984 Protocolo de intensões SSMA/MS/OPAS
Encontrei hoje esta proposta de época um próxima a que me aposentei na Secretaria da Saúde, onde nossos objetivos eram ações relacionadas com o controle de Doenças Crônicas, Promoção da Saúde e pretendíamos desenvolver ações mais específicas relacionadas com os idosos.
Em seguida, quando retornei para a Faculdade de Medicina propuz a criação das Disciplinas de Promoção e Proteção da Saúde em substituição às de Acompanhamento de Família que estavam fadadas a serem extintas. A minha PPSIII dedicava-se ao Adulto, incluíndo o Idoso.



Cannabis x Tabac

Jugée "meilleure au goût" que le tabac, moins "dangereuse" et "plus saine", l'herbe de cannabis a une image positive et "dédramatisée" auprès des adolescents, selon une étude de l'Observatoire français des drogues et des toxicomanies (OFDT) publiée mardi.

Chronic pain

Holding your partner’s hand can ease their pain

Around 100 million adults in the United States are affected by chronic pain — pain that lasts for months or years on end. It is one of the country’s most underestimated health problems. The annual cost of managing pain is greater than that of heart disease, cancer and diabetes, and the cost to the economy through decreased productivity reaches hundreds of billions of dollars. Chronic pain’s unremitting presence can lead to a variety of mental-health issues, depression above all, which often intensifies pain. And our most common weapon against pain — prescription painkillers — generates its own pain, as the ongoing opioid crisis attests. But must we rely on pharmacology to stave off pain? Perhaps there is a more natural nostrum — partial and insufficient, but helpful nonetheless — closer to hand.

The typical cell phone user touches his or her phone 2,617 times every day, according to a study by research firm dscout. And that’s just the average user -the study found that extreme cell phone users (meaning the top 10%) touch their phones more than 5,400 times daily.
Actions like typing, tapping, and swiping the phone’s screen counted as a ‘touch. Apple recently confirmed their device users unlock their phones 80 times every day. That’s about 6 to 7 times every hour./.../

How an unlikely cellular ‘antenna’ can impair brain development

Disruption of a neuron structure called the primary cilium leads to defects in brain development resembling those seen in neuropsychiatric disorders.

CHAPEL HILL, NC – An antenna-like structure on cells, once considered a useless vestige, appears to be important for proper brain development in mammals and when impaired can cause defects in the brain’s wiring similar to what’s seen in autism, schizophrenia, and other neuropsychiatric disorders. In lab experiments, UNC School of Medicine scientists prevented these wiring defects by restoring signaling though these antenna-like structures called primary cilia.

What Makes the Hardest Equations in Physics So Difficult?

The Navier-Stokes equations describe simple, everyday phenomena, like water flowing from a garden hose, yet they provide a million-dollar mathematical challenge.

Physics contains equations that describe everything from the stretching of space-time to the flitter of photons. Yet only one set of equations is considered so mathematically challenging that it’s been chosen as one of seven “Millennium Prize Problems” endowed by the Clay Mathematics Institute with a $1 million reward: the Navier-Stokes equations, which describe how fluids flow.
Last month I wrote a story about an important new result related to those equations. If anything, the new work suggests that progress on the Millennium Prize will be even harder than expected. Why are these equations, which describe familiar phenomena such as water flowing through a hose, so much harder to understand mathematically than, say, Einstein’s field equations, which involve stupefying objects like black holes?

PH Interventions

Journal of Epidemiology & Community Health
Dear Aloyzio,

It can be difficult to stay on top of the latest research and discussion in your field, so we've highlighted an interesting article recently published that we hope you enjoy!

Return on investment of public health interventions: a systematic review

Assumindo os 70% de chance...

Há dez anos atrás, não lembro qual jornalista, enviou-me um questionário cujas respostas re-encontrei ontem. Ao quase se completar o período para o qual estimei minha chance de sobreviver, achei que seria hora de publicar o texto e desafiar minha capacidade de previsão...
Não mudaria nada nas respostas, apenas duas descobertas a mais acrescentaria como interessantes: 

  1. a ideia de que tudo está interconectado (no espaço e no tempo) mesmo quando nossa percepção não alcança - dentro de nos (até o microbioma), no ambiente, mas muito mais além, até na dimensão cósmica.
  2. nossa mente não é propriedade de cada um, nem se restringe ao cérebro ou ao corpo humano, mas se estende e está em permanente intercâmbio com as pessoas e o mundo no qual vivemos.
Continuo conectado principalmente com amigos que queiram trocar ideias sobreo assunto.


PERGUNTAS PARA RESPONDER:
(Hoje, 03/07/2008 – meu nascimento em 01/07/1934)
Diga-me o que o amedronta mais?
A insanidade mental.
Qual é a coisa que você mais quer?
Ver minha família feliz, realizada e segura, num ambiente de paz.
E o que você mais odeia?
A desonestidade. Eu ia responder a violência, mas odiar e faltar com a verdade são formas de violência...
O que você mais ama?
Oportunidade de comunicação
Qual a coisa mais interessante que observou recentemente?
A hipótese de que vivemos num "multiverso", e não num universo.
E como você vê sua vida no futuro?
Com 30% de probabilidade de morrer dentro dos próximos dez anos, ou se quiserem, com uma probabilidade de 70% de sobreviver um pouco mais; entretanto com tempo insuficiente para completar tudo aquilo que desejaria fazer. Acho melhor assim do que pensar que tudo está acabado e que não teria mais o que fazer na vida...
O que é terra natal pra você (poderíamos substituir por: o que é Porto Alegre para você? Ou como vê Porto Alegre?)
Terra natal é onde se nasce. Para mim é Santa Maria. Entretanto Porto Alegre é onde vivo há mais de 50 anos e onde consegui me realizar junto com minha esposa e minha família. Se fosse possível superar a desigualdade social existente, diria que poderia ser a cidade ideal para se viver.
E onde você quer viver?
A resposta a pergunta anterior pode ser considerada também como resposta para esta última. Já pensei em viver em Genebra ou Washington (onde tive chances e convites para ficar). Pensei também em viver na Noruega; mas, ainda mais agora, desejo viver o que me resta em Porto Alegre (na Avenida Bastian, 212).

[Let’s Make Communication Great Again] — How the Nature of Words Should Impact Your Communication

A Primer on Language and its implications for the entangled web of our existence as fellow human beings sojourning through the earth.
Go to the profile of Tyler Kleeberger
so obviously, I am [not] an expert) and what it means for your life.
Let’s start with two questions and a quote:

If you hear the word “orange”, what comes to mind?

It’s an important question for one reason — multiple options can be represented by the same word.
This is the problem with language. We are not given a pre-determined
set of words with their singular meaning. Would that make
communication easier? Probably. But you can say, “Orange” and
mean a color or a fruit or maybe something else entirely./.../
