It’s Time for a Break?


How Your Brain Tells You When It’s Time for a Break

New
 research published in the Proceedings of the National Academy of Sciences offers insight into how people decide when to keep going and when to take a break.  That decision apparently hinges on a specific signal that at its peak— say, when your muscles are screaming that you can’t do another rep or your brain refuses to focus on the page — prompts you to quit. And when your body and brain are refreshed and ready to go again, the signal quiets down and gets out of your way.Are you reading this when you should be working?  If so, then it may be because your brain signaled that continuing to work was not worth the cost in tedium of forcing yourself to stay on task./.../

GLOBAL LEADERS IN CARDIOVASCULAR DISEASE HEALTH – PROFS K. SRINATH REDDY AND SALIM YUSUF – POISED TO DO BATTLE AGAINST THE WORLD’S NUMBER ONE KILLER



Geneva, 28 January 2013 – The election of two of the world’s leading experts in cardiovascular disease (CVD) prevention and control has given the World Heart Federation powerful leadership, and a strategic advantage, in ensuring commitments made by governments to reduce non-communicable disease (NCD) deaths by 25 per cent by 2025 are delivered on. CVD accounts for about one-third of deaths worldwide and are the leading cause of deaths and disability. Prof. Srinath K. Reddy, MD, DM, MSc took over as President and Prof. Salim Yusuf, DPhil, FRCPC, FRSC as President Elect, effective as of 1 January. 

Immediate Past President, Prof. Sidney C. Smith Jr, MD said “I am honored to have led the World Heart Federation during one of the most exciting periods in the history of CVD health. Guiding the success of the World Congress of Cardiology and participating in the United Nations High-Level Meeting on the Prevention and Control of NCDs in 2011, together with Heads of State, to help shape the global health agenda were particular highlights of my presidential term. The organization could not be handed over to more capable hands. Professor Reddy is recognized internationally as a global thought leader on issues associated with public health and CVD, and is a highly respected CVD leader in India. While Professor Yusuf born in India and now of Canada, is the second most read and talked about scientist in the world in a ranking by Science Watch.  Professors Reddy and Yusuf’s thought leadership and pioneering approaches to CVD science and its direct application to health policies will strongly position and enable the World Heart Federation to combat the world’s number one killer – CVD – which causes 17.3 million deaths each year. Their expertise will lead to new strategies, not simply follow existing approaches.” /.../

Can Neanderthals be brought back from the dead?

George Church (credit: Steve Jurvetson/Wikimedia Commons)
In a SPIEGEL interview, synthetic biology expert and Harvard University professor of genetics George Church explains how DNA will become the building material of the future — one that can help create virus-resistant human beings and possibly bring back lost species like the Neanderthal.
In his new book, “Regenesis: How Synthetic Biology Will Reinvent Nature and Ourselves,” which he has also encoded as strands of DNA and distributed on small DNA chips, Church sketches out a story of a second, man-made Creation.
SPIEGEL:Mr. Church, you predict that it will soon be possible to clone Neanderthals. What do you mean by “soon”? Will you witness the birth of a Neanderthal baby in your lifetime?
Church: That depends on a hell of a lot of things, but I think so. The reason I would consider it a possibility is that a bunch of technologies are developing faster than ever before.
In particular, reading and writing DNA is now about a million times faster than seven or eight years ago. Another technology that the de-extinction of a Neanderthal would require is human cloning. We can clone all kinds of mammals, so it’s very likely that we could clone a human. Why shouldn’t we be able to do so?

Diversos patógenos intracelulares evoluíram para subverter as funções de células hospedeiras em seu próprio benefício. Entre eles incluem-se os da tuberculose, da malária e da hanseníase.
A hanseníase é uma doença crônica causada pela Mycobacterium leprae, uma bactéria em forma de bacilo que inicia sua infecção a partir das células de Schwann, o que acarreta lesão neurológica caracterizada por perda sensorial e motora nos pacientes afetados.
Células de Schwann têm esse nome em homenagem a Theodor Schwann, pesquisador alemão responsável pela teoria celular e pela descrição original dessas células gliais, presentes no sistema nervoso periférico.
As células de Schwann podem envolver os neurônios, como a borracha que encapa um fio elétrico, formando uma bainha lipídica conhecida como mielina e que facilita a transmissão do impulso nervoso.

Citing Articles (1)
The disease risks from cigarette smoking increased over most of the 20th century in the United States as successive generations of first male and then female smokers began smoking at progressively earlier ages. American men began smoking manufactured cigarettes early in the 20th century; by the 1930s, the average age at initiation fell below 18 years.1,2 Relatively few women smoked regularly before World War II; their average age at initiation continued to decrease through the 1960s. Women were not included in the earliest prospective epidemiologic studies in the 1950s,3-5 since mortality from lung cancer among women was not yet increasing in the general population.6 The landmark 1964 U.S. Surgeon General's Report concluded only that “cigarette smoking is causally related to lung cancer in men.”7 Neither sex had yet experienced the full effects of smoking from adolescence throughout adulthood./.../

Antiquus Morbus is a collection of archaic medical terms and their old and modern definitions.  The primary focus of this web site is to help decipher the Causes of Death found on Mortality Lists, Certificates of Death and Church Death Records from the 19th century and earlier. This web site will be updated often and as new information is received. My intention is to collect and record old medical terms in all European languages. The English and German lists are the most extensive to date.
Each term is only listed once. Check under the other headings if the term is not in the alphabetical lists. Also, try the Google search tool below.

 Please send me an email with any unlisted words or phrases that you have come across. They will be added to the "undefined" page after review. All new terms will eventually be added to the alphabetical lists. Please include the language that the term is from.
am happy to help transcribe and translate your hard to read Causes of Death. If possible, please include a scan of the record with your email. It is always more helpful to see the handwritten original when trying to figure out the difficult words.
Please email to me your examples of causes of death so that I can paste them into the web site. I rely on your help to make this website accurate, thorough and interesting by including your input and feedback.

New Evidence That Cigarette Smoking Remains the Most Important Health Hazard

Everyone knows cigarette smoking is bad for you. Most people in the United States assume that smoking is on its way out. But the grim reality is that smoking still exerts an enormous toll on the health of Americans, as documented in two articles in this issue of the Journal.1,2 Both articles review mortality trends over time for men and women according to smoking status, and both confirm that smoking remains a huge threat to the public's health.
Jha et al. review data from the U.S. National Health Interview Survey, which involved 113,752 women and 88,496 men 25 years of age or older who were interviewed between 1997 and 2004. The investigators examined the rates and causes of death by the end of 2006.1 Within the age group 25 to 79 years, the mortality of current smokers of both sexes was three times that of participants who had never smoked. Diseases attributable to smoking accounted for about 60% of smokers' deaths. The benefits of quitting smoking were dramatic for all age groups, with substantial gains in life expectancy, as compared with participants who had continued to smoke. Those who quit between the ages of 25 and 34 years lived 10 years longer; those who quit between ages 35 and 44 gained 9 years, those who quit between ages 45 and 54 gained 6 years, and those who quit between ages 55 and 64 gained 4 years. These differences persisted after adjustment for such potentially confounding variables as educational level, alcohol use, and adiposity./.../
