It’s been nearly two dozen centuries since Hippocrates, the “Father of Western Medicine,” walked the Earth; yet his famous quote, “Let food be thy medicine and medicine be thy food,” rings truer than ever.
A medicina demorou mais de 2000 anos mas agora testou a eficácia da atenção plena no tratamento desses transtornos. O resultado é surpreendente
No dicionário Houaiss, dor é uma “sensação desagradável”. Aflição interna, não pode ser calculada por exames e segue, 200 anos após a descoberta da morfina, assunto não resolvido para a medicina. Remédio demais vicia, remédio de menos não faz efeito. Na década de 70, uma alternativa à química se abriu com o trabalho do americano Jon Kabat-Zinn, um biólogo empolgado com a meditação. Ao adaptar técnicas orientais, ele montou um programa de exercícios para o cérebro e convidou pacientes insensíveis a analgésicos a testá-lo. O alívio veio rápido.
A study led by Indiana University School of Medicine researchers demonstrates how electroacupuncture triggers a neurological mechanism that can help promote tissue repair and relieve injury-induced pain.
Their findings, published online in the journal Stem Cells, provide the most comprehensive picture yet of how electroacupuncture stimulates the brain to facilitate the release of stem cells and adds new insight relating to the cells’ healing properties. Leer Más
Dr Kanwarjit Singh Duggal speaking at the United Nations, March 10, 2017, on “Cultivating Inner Peace for Outer Peace”, as guest of United Nations SalusS Well-being Network
UNITED NATIONS (TIP): When you can go to the United Nations to hear a talk about meditation, you know something has changed in the world.
On Friday, March 10, 2017, Dr. Kunwarjit Singh Duggal, guest of the United Nations Salus Well-Being Network, spoke to a packed audience in the Secretariat Conf. Room 8 on “Cultivating Inner Peace for Outer Peace.” He began: “My main message here is to talk about peace. How do we achieve peace? . . . In order to take peace to the next level, we have to find peace within ourselves first before we can go on helping the rest of society.”
By his own admission, Dr. Duggal is quite passionate about meditation as an intervention for many of life’s challenges, whether worldly or personal – a universal paradigm.
His topic on Friday, particularly timely today,detailed the latest scientific research on theproven benefits of meditation. Noting the many different types of meditation, he talked about several significant studies, most focused on peace, stress and anxiety.
He quoted one randomized controlled study in which people were asked to meditate each morning for 21 days straight for a short duration of time. The researchers measured cortisol (the stress hormone) levels before and after 21 days and found a significant decrease in every participant. Notable studies also found that for patients undergoing orthopedic rehabilitation those who meditated benefitted twice as much as those who were treated only with therapeutic exercise.

- Summary:A study has uncovered key molecular pathways behind the disruption of the gut’s delicate balance of bacteria during episodes of inflammatory disease.
“A deeper understanding of these pathways may help in developing new prevention and treatment strategies for conditions such as inflammatory bowel disease (IBD) and certain gastrointestinal infections and colorectal cancers,” said Dr. Sebastian Winter, Assistant Professor of Microbiology and a W.W. Caruth, Jr. Scholar in Biomedical Research at UT Southwestern, who led the study.
More than 1 million people in the U.S. suffer from IBD, a chronic, lifelong inflammatory disorder of the intestines that has no cure or means of prevention.
Bruce Lipton reclama una nueva medicina, la que tenga en cuenta la energía por su capacidad para curar.
Reclama una nueva medicina, la que tenga en cuenta la capacidad de curar de la energía, mucho más eficaz que los medicamentos. Bruce Lipton (Estados Unidos, 1944) ha conseguido aunar ciencia y espíritu. No es poco mérito el suyo si tenemos en cuenta lo “alérgicos” que son los científicos a los temas trascendentales. Es doctor en Biología Celular y fue pionero en la investigación con células madre. Sus estudios sobre la membrana celular y las modificaciones de las células según el entorno sentaron las bases de la nueva epigenética. Sus descubrimientos (que iban en contra de la opinión científica establecida de que la vida es controlada por los genes) y el estudio de la física cuántica le han llevado a criticar duramente la medicina convencional. Es autor de libros como La biología de la creencia y La biología de la transformación.
The human body is made up of roughly 10 trillion cells. That’s a huge number, but it’s dwarfed by the 40 trillion or so bacterial cells that live on and inside the body.
In recent years, scientists have learned that our bacteria — known collectively as the microbiome — are intimately involved with many aspects of our health, including the robustness of our immune system and our risk of developing asthma and allergies. Now, new research suggests that the microbiome may also play a key role in neurological and psychological disorders.
“At a basic neuroscience level, all the key mechanisms of the brain have been shown to be regulated by the microbiome,” says John Cryan, a neuroscientist at University College Cork in Ireland.
As scientists investigate how the microbiome impacts our bodies and minds, some experts envision fundamental changes in the way doctors diagnose and treat disease.
“Someday soon, you and I will go into the doctor’s office, and the doctor will prescribe medicine that won’t be a chemical from a lab, but may be live bacteria,” says Sarkis Mazmanian, a microbiologist at Caltech in Pasadena, California. “In addition to blood work, yearly physicals may include fecal samples to profile the microbiome,” tracking changes in bacteria to predict your risk for illness, sometimes long before symptoms appear.
The positive health effects of live bacteria have already been hinted at through research on prebiotics and probiotics, which scientists think may play an integral role in your immune system and on how you feel. New studies show that far more diseases may be impacted by the microbiome than previously understood.
“Bacteria could eventually be used in lieu of chemical treatments,” Cryan says. He’s even coined a term to describe the possibility: psychobiotics, adding that, “Within five years, we’ll have specific microbial-based treatments.”
Breakthroughs in Bacteria
In December, Mazmanian’s lab revealed preliminary evidence linking the microbiome to Parkinson’s disease, which as a neurodegenerative disorder has long been believed to be a disease of the brain, not the gut.
“At first we were in disbelief with the results,” Mazmanian says of the research, which was done in rodents. “We kept testing and it kept leading us back to the same conclusion.”
More investigation is necessary, but this new understanding of Parkinson’s could help researchers find better ways to treat it. Future studies could identify which microbes are involved, and then researchers might be able to develop targeted bacterial treatments to help combat the disease.
This result isn’t just true of neurodegenerative disorders: There’s also evidence that disturbances of the microbiome might be a factor in psychological illnesses, too. Cryan has shown that a particular bacterium works as well as a popular antidepressant in reducing levels of stress hormones in animals subjected to stress tests.
Furthermore, researchers at Baylor College of Medicine found in a 2016 study that one species of gut bacteria causes social deficits in mice similar to autism in humans. By adding the bacteria back to the guts of affected mice, researchers were able to reverse their behavioral deficits.
Although further evidence linking the microbiome to these and other illnesses in human trials will be necessary, we’re already seeing changes in the way doctors treat certain conditions.
Take infections with the deadly bacterium Clostridium difficile, which each year kill 14,000 Americans. The condition is notoriously difficult to treat, but doctors are finding it can often be cured with fecal transplants — fecal material taken from someone with a healthy microbiome and delivered to the patient’s colon. By introducing helpful bacteria, the treatment can combat the illness better than antibiotics can.
Out of Balance
Martin Blaser, director of the Human Microbiome Project at New York University, points to several causes for the imbalance of someone’s microbiome, including the overuse of antibiotics, the use of antibacterial rinses for our food and sanitizers for our skin, and even the popularity of cesarean sections. (Ordinarily, we get our microbiomes from our mothers as we move through the bacteria-laden birth canal during childbirth — but, of course, that doesn’t happen to babies born via C-section.)
As a result of these factors, some species of bacteria are disappearing in developed countries, leading to a disturbance of bacterial populations in the body. Helicobacter pylori, for example, is one such bacterium that seems to disappear with the use of antibiotics. Although it’s associated with stomach ulcers, esophageal diseases and even cancer seem to spike when it’s absent from the body.
Blaser explains this is not uncommon. He believes the loss of diversity in our microbiomes is a factor in a range of modern plagues that includes diabetes, cancer, and even obesity.
“Microbial bacteria were the first form of life on earth, and the most numerous,” Blaser says, and everything that subsequently evolved, like humans, had to take bacteria into account. “The whole biosphere requires the presence of bacteria.” We’re still just learning what that might mean.

São Paulo – Uma invenção que custa menos de um real pode mudar a medicina e salvar vidas em países pobres e locais sem infraestrutura. A criação foi batizada de “Paperfuge”, uma junção de paper (papel) e centrifuge (centrífuga).
Ele foi desenhado por pesquisadores de Stanford. Um deles, Manu Prakash, um professor assistente de bioengenharia da universidade de Stanford, tem como linha de pesquisa a criação de soluções baratas com foco no cuidado da saúde em países pobres.
O Paperfuge se encaixa bem nesse trabalho: seus materiais saem por cerca de 20 centavos de dólares (perto dos 60 centavos brasileiros) e pode ter grande impacto no mundo.
As centrífugas são equipamentos cruciais para a detecção de portadores do vírus HIV, confirmação de casos de malária, entre outros procedimentos médicos.
