What to eat against high blood pressure?

In the circulatory system of our body, the force of its blood when pushing against the walls of the arteries is known as blood pressure.

High blood pressure, also known as hypertension, occurs when the blood pressure is causing the walls of the arteries to expand. This pressure can cause damage to the blood vessels that often leads to heart disease, stroke, among other problems that threaten our lives.

Some healthy foods can prevent, decrease and even reverse the heart damage caused by high blood pressure.

Oatmeal is one of these foods with heart-healthy benefits. These heart-healthy benefits arise due to the ability of oats to offer high fiber content, which is low in fat and low in sodium.

Bananas have several healthy vitamins such as vitamins C and B-6. They also contain carbohydrates, proteins, fiber and magnesium. Bananas are good for the heart because they contain potassium that helps lower blood pressure by balancing the negative effects of salt.

Salt holds water, which can be problematic if your kidneys can not get rid of it. Potatoes also have potassium. One potato, contains approximately 897 mg of potassium. That is 25% of the recommended amount.

We just have to make sure that the potatoes are not too salty. Berries – like blueberries, strawberries, raspberries and blackberries – are good for the heart, because they are a source of polyphenols, micronutrients and fiber.

Data

* Healthy or normal blood pressure is characterized by being more than 120 over 80 and less than 140 over 90. If it is higher than that range, say 150/100, it would be considered that you have high blood pressure, which could be cause for concern.

* Oats, bananas, potatoes and berries are good for blood pressure.

Authorities confirm 46 new cases of Ebola in just 7 days in DR Congo

The number of infections in this Ebola epidemic reaches 419 cases

A total of 46 new cases of Ebola were recorded in the northeastern Democratic Republic of Congo from 19 to 25 November, according to data released today by the African Ministry of Health.

The number of infections in this Ebola epidemic, which is already considered the largest in the history of the Democratic Republic of Congo, reaches 419 cases, of which 372 were confirmed in a laboratory and 47 are probable.

The number of likely deaths since the outbreak was reported on 1 August in the provinces of North Kivu and Ituri has reached 240, of which 193 tested positive, according to official figures dated 25 November.

In addition, this is the first time that an Ebola epidemic has an epicenter in a conflict region, where they operate around 100 armed groups, which generates a daily displacement of thousands of people who may have had contact with the virus and also imposes limits on the safety and health work of health professionals.

In order to contain the number of deaths, the NGO Alliance for International Medical Action (Alima) announced yesterday the implementation – thanks to an international consortium coordinated by the World Health Organization (WHO) – for a new clinical examination treatment center in the city of Beni in North Kivu.

This last epidemic of Ebola is the most serious in the entire history of the Democratic Republic of Congo in relation to the number of cases since it surpasses the record of 318 contagious registered in 1976 during the first outbreak of the virus in Yambuku, in the northwestern province of Ecuador.

Can Alzheimer’s be prevented?

Its genetic component does not necessarily imply that the whole family develops the disease. Although Alzheimer’s has a genetic component and, therefore, can be inherited, it is possible to delay its development or even deactivate this possibility if certain recommendations related to food and cognitive activities are followed. This was stated by Sonia Zevallos, a psychiatrist at the Directorate of Adults and Older Adults of the National Institute of Mental Health.

“Genetics gives you the predisposition. That means that of so many people you have a greater risk of developing Alzheimer’s, but this is not necessarily something one hundred percent sure that you will develop it, “he explained.

He indicated that when the disease is already diagnosed, the only treatment is left to slow down its progression, in addition to offering the quality of life to the sufferer.

While there are no magic recipes for the disappearance of Alzheimer’s from our path, there are things we can do to keep it as far away as possible and minimize the possibility of losing our learning faculties and moving autonomously through life.

Remove fats

“One of the first recommendations is to consume less polyunsaturated fats, less fat derived from meat. As we have an excellent cuisine, but we often use the fat of pork, beef, butter, which generates many free radicals, favors oxidation processes and unfortunately that accumulates. “

Suggested to reduce the consumption of red meat and favor the fish, seafood that has large amounts of Omega 3. Similarly, prefer vegetable oils, such as sunflower, coconut, among others.

“Among the vegetables, the most recommended are broccoli, spinach. Eat nuts and follow a Mediterranean diet. Less flours and stay always, always active. You’re never so old that you can not learn something new, “he said.

The expert said that her patients recommend having an agenda to write down what has to be done so as not to overload the memory.

“There are many things that influence memory. If I have many things to do and I’m going to a thousand per hour: I have to see my son do homework, I have to pay for college, go to work early, take care of my dad, solve the things my husband asks me, then it is impossible to keep my attention one hundred percent in everything I do . “

That means that at some point we will forget to do some things and that is natural due to the stress generated by doing several things at the same time.

“The problem is that we seek to serve everyone and the question is, what do I do for myself? It is essential to have spaces for oneself. Not as a doctor, wife or sister. Only for me. You have to think, how did I get angry? How do I meditate? How do I relax or in what spaces do I find myself?

Brain inactivity

In addition to the above, Dr. Zevallos stressed the need to keep our cognitive and intellectual functions active at all times.

Whether or not you have a relative with Alzheimer’s, he stressed the urgency of training our brain permanently, but without overwhelming it.

“We must protect our cognitive functions, as it could be with the crossword, where remote memory is recovered and for that you must have understood the question. Activate several functions “.

He pointed out that one very easy thing to do is play cards, where calculation, attention, memory, judgment, strategy, planning are used. Although clear, without betting.

“Alzheimer’s can not be cured, but it can be prevented and attenuated, giving a better quality of life to the person who suffers it and thereby favoring their autonomy so that they do not depend so much”.

He regretted that many children with parents who suffer from this disease prevent them from doing things at home and that is how they put their mother in bed or sitting watching television, “plugged in and without training the memory.”

Scientists use eye movement to diagnose multiple sclerosis

Multiple sclerosis, still uncured, is triggered by the combination of environmental, genetic and infectious factors.
Globally there are 2.3 million people with this disease and, on average, the diagnosis is usually made at 30 years of age.

Multiple sclerosis can be diagnosed through eye movement, according to the findings of a group of Portuguese scientists at the University of Minho who studied the disease for four years.

For the first time, it was demonstrated that eye movements can reveal cognitive changes in people with multiple sclerosis, according to Efe Agency, one of the seven researchers of the group, Paulo Alexandre Pereira, Ph.D. in Mathematics at the University of Minho.

The findings of this research, which have just been published in the American journal “PeerJ”, will be of great use to choose new treatments, fight this disease of the nervous system and apply new techniques or treatments that attenuate the progression of multiple sclerosis.

The hypothesis came from the realization that patients suffering from this disease may have problems with the optic nerve, which is why scientists decided to take another step and start a more exhaustive research.

The studies focused on a sample of half a hundred people from the Portuguese province of Braga – where the university is – who have multiple sclerosis and many others who do not suffer from the disease.

Through the use of ophthalmic devices, it was proven that “reaction times between patients and healthy ones were quite significant,” said Paulo Alexandre Pereira.

It was thus corroborated that the reaction time to look at one side or the other was much greater in patients.

In this way, the scientists have proven their hypothesis and have been able to advance in one of the final objectives, which is the cheapness and the effectiveness of the diagnosis of this disease.

Currently, according to Pereira, the first diagnosis of multiple sclerosis is performed by means of an MRI, although in some cases “there may be confused with other diseases”, which does not make it reliable.
To supplement the examination, fluid is extracted from the spinal cord using a lumbar puncture.

“What we want to do, while we are still far away, is that family doctors may have devices similar to those of ophthalmologists to reliably diagnose multiple sclerosis,” he explained.

On many occasions, the diagnosis is not easy and it takes a long time for you to discover the disease, something that would be solved with this test.

In addition, the family doctor could check the evolution of the disease in the patient and, thus, apply more appropriate treatments.

Although they have already reached an important phase of the research, Paulo Alexandre Pereira anticipated to Efe that the group of the University of Minho will continue investigating the movement of the eyes and will take another step on the diagnosis, since they will analyze – in a second phase – the perception that multiple sclerosis patients have the colors.

“For now, we do not know, but we believe that there is also a relationship between the perception of colors and the disease,” said the Portuguese scientist.

The multidisciplinary team that works in this project is formed by physicists, mathematicians, biologists and physicians Marisa Borges Ferreira, Paulo Alexandre Pereira, Marta Parreira, Inês Sousa, José Figueiredo, João Cerqueira, and António Filipe Macedo.

Multiple sclerosis, still uncured, is triggered by the combination of environmental, genetic and infectious factors.
Globally there are 2.3 million people with this disease and, on average, the diagnosis is usually made at 30 years of age.

Scientists modify breast milk molecule to fight cancer

Scientists at the University of Graz in Austria have discovered that lactoferricin has regressed human cancer cells in rats.

A team of scientists from Austria has been able to modify a molecule derived from a breast milk protein to act as a cancer detector and attack malignant cells in certain types of the disease that are difficult to treat.

The research focuses on lactoferricin, a peptide (a type of molecule) in breast milk that was already known for its antimicrobial properties, according to a statement from the University of Graz in southern Austria on Monday.

Image result for Scientists modify breast milk molecule to fight cancer

What the researchers at this institution did was to modify this molecule to act as a detector for certain types of cancer that are difficult to treat, such as melanoma and glioblastoma, a type of brain tumor.

This modified lactoferricin is able to localize the negative charge of the phosphatidylserine molecule present on the membrane of cancer cells, adhere to it and cause its death, but without affecting healthy cells.

“The biggest challenge in the development process was finding the right balance between toxicity and specificity. If the peptides are very active, they also attack the healthy cells, “said Dagmar Zweytick and Sabrina Riedl, two of the research team, in the note.

Lactoferricin is a derivative of the lactoferrin protein, which is abundant in breast milk. Lactoferricin is part of the immune system and is one of the first defenses against foreign bodies such as bacteria and fungi.

The use of the substance in the fight against cancer requires a restructuring of its amino acids to achieve the right combination.

Results
The team at the University of Graz developed 15 variants of lactoferricin over four years of research. Two of these were used in rats to which human cancer cells were transplanted.

The scientists observed an average regression of 85% in the case of melanoma and 50% in glioblastoma, compared to animals not treated with the peptide. In addition, healthy rats treated with this agent were not harmed.

The Zweytick-led team is working on improving this agent and collaborating with a pharmacist in the preparation of clinical trials starting in 2019.

Austria announces clinical trials for zika vaccine

After success in preliminary studies, the Viennese company selects volunteers for new vaccine test against Zika

A prototype zika vaccine was developed by a Viennese company, which launched a clinical trial in humans, open to volunteers worldwide after checking its possible efficacy in preliminary studies.

In a statement released today, the Austrian company Themis Bioscience explains that the new vaccine is based on the same technology that was applied to successfully develop another vaccine against Chikungunya fever.

The company says the recombinant DNA technology (which uses DNA sequences from two different organisms) has been applied to the new vaccine and, in its view, “promises a rapid and effective immune response.”

The vaccination program “is based on a live attenuated vaccine (the type of immunization already used in the prevention of polio, rubella and measles, which consists in inoculating the same virus that causes the disease, but manipulated to reduce its risk and to stimulate the body’s defenses in fighting it, “the note said.

In the first phase of the clinical study, three treatments with different dosages were tested in 48 volunteers, in order to identify the most adequate for its protective effect and tolerance.

The study, which is open to volunteers by the end of this month, is conducted at the Department of Clinical Pharmacology and the Institute of Specific Prophylaxis and Tropical Medicine at the Medical University of Vienna, and its first results are expected within six months.

It is the “first worldwide study of a live attenuated recombinant DNA vaccine against zika,” Erich Tauber, president and founder of Themis, said in a statement.

“The attenuated vaccines are considered better because they induce a faster and more complete activation of the immune system, with a lasting immunity, he explains.

Zika has been of great international concern since its relationship with cases of microcephaly in newborns, initially in Brazil and in Polynesia, and other neurological disorders that may affect all have been discovered.

The Zika virus is transmitted through the bite of the Aedes aegypti mosquito, which transmits dengue, chikungunya and yellow fever, and among humans, contagion can be through sexual intercourse.

Habits and environment are most responsible for cancer

Daily factors prevail over genetics and heredity in the development of the disease

Attributed normally to genetic and hereditary factors, the onset of cancer is linked more to aspects related to the habits and environment in which one lives than to a biological predisposition.

Cancer is a name for more than 100 diseases with one feature in common: the abnormal proliferation of cells in the body.

Image result for Habits and environment are most responsible for cancer

“Although it is not evident because the cells start to behave in a disorderly way, the causes of this lack of control are an interaction between genetic predisposition and the environment, in the sense of the conditions in which we live and the habits we adopt,” explained the director of the cancer center of the Beneficência Portuguesa Hospital in São Paulo, Antonio Buzaid during an oncology event organized by Bayer in São Paulo on May 2-3.

Experts expect that genetic syndromes will account for a maximum of 10% of the world’s cancer cases. The other cases are related to the environment or were made possible by environmental stimuli in an unfavorable genetic condition.

A study published in the New England Journal of Medicine, quoted by Buzaid, looked at thousands of twin siblings, identical or otherwise, to relate the incidence of cancer to genetic aspects. In the case of identical twins, the DNA is totally equal, whereas in the case of the identical twins they are very similar.

The results of this study presented by the doctor indicate the thesis that the medium is the main responsible for the onset of cancer. Of all pairs of twins, in only 14% of cases where one of the siblings developed cancer, the other had a similar problem.

Image result for Habits and environment are most responsible for cancer

Environment and habits

There are several variables that can be included in what is called an “environment” that favors the development of cancer. “Habits like smoking, consuming too much-saturated fat, eating too hot tea, or carrying certain types of viruses, such as HPV or hepatitis, are environmental factors that can contribute to cancer on many fronts,” says Buzaid.

Smoking is the main cause for the development of the disease. It is estimated that 80% of lung cancer cases and up to 1/3 of the general cases are caused by cigarette smoking.

Another cause of cancer indicated by the specialist is the feeding. “There are many foods that can cause cancer, even more, if consumed in excess, such as industrialized and fatty,” warns Buzaid.

The WHO classifies potential carcinogenic foods according to the proven relationship between their consumption and the development of the disease. Red meats, for example, are classified as “2a”, which suggests “probable relationship with cancer”. Processed meats, such as sausages, sausages, and sausages, are classified as “1”, that is, proven carcinogenic.

Study says smoking may increase stress sensitivity

“The researchers also found that a mouse exposed to a single aggression shows signs of stress only been exposed to nicotine,” the study said.

Smoking can increase stress sensitivity, according to a study in mice by the National Center for Scientific Research of France (CNRS) and published on Tuesday in the journal ” Molecular Psychiatry .”

Image result for Study says smoking may increase stress sensitivity

Contrary to popular belief that smoking has a relaxing effect and that a lack of nicotine produces stress, exposure to this addictive molecule may produce the opposite effect, the researchers said in a statement.

The scientists evaluated the levels of social stress in rodents, a situation that occurs when “one of these animals is subjected to repeated aggression from the dominant ones.” In this circumstance, some mice blocked the nicotine receptors, while others activated.

From the evaluation of behavior and electrophysiological parameters of the brain, the CNRS experts established that no signs of social stress appear when the receptors are blocked and on the contrary, they were amplified.

“The researchers also found that a mouse exposed to a single aggression shows signs of stress only been exposed to nicotine,” the study said.

Although the work focuses on how nicotinic receptors affect the control of stress in mice, the CNRS has announced that scientists will examine whether this situation can be amplified for all mood disorders and whether the results are applicable to humans.

Japanese AI system allows early diagnosis of skin cancer

The system employs deep learning, a programming based on complex algorithms capable of analyzing images and relating certain patterns that are repeated in the development of malignant cells that lead to melanoma.

Japanese technology company Kyocera and the University of Tsukuba, Japan, developed a system to detect skin cancer in its initial phase, from the analysis of photographs of patients using Artificial Intelligence (AI).

Image result for Japanese AI system allows early diagnosis of skin cancer

The method, still in the experimental phase, reached a precision in its diagnoses of 90% in 4 thousand analyzed snapshots of patients’ skin, according to the Japanese newspaper “Nikkei”.

The system designed by Kyocera employs deep learning, a programming based on complex algorithms capable of analyzing images and relating certain patterns that are repeated in the development of malignant cells that lead to melanoma.

Researchers at the University of Tsukuba plan to create more variants of the matrix program applicable to the diagnosis of other diseases, including contagious diseases.

Kyocera and the university are expected to start distributing a prototype of the system by next year, at hospitals in the country, with the idea of marketing it in 2019, says the Nikkei.

The medical applications of AI could help cope with the increased demand for services in Japan as a result of the accelerated aging of the population, a trend that has led to a shortage of health professionals.

Other Japanese technology companies, such as Hitachi, NEC, and Toshiba, are also developing medical diagnostic systems based on imaging and artificial intelligence.

The government intends to promote these applications of AI, whose potential was highlighted in a report by the Ministry of Health in June and is expected to offer economic benefits to companies that invest in the sector.

French doctor performs first surgery with augmented reality vision

Equipped with a special helmet designed by the American company Microsoft, the doctor was able to visualize the patient’s skeleton and tendons in great detail.

French doctor Thomas Grégory performed the first operation in the world on Tuesday using a helmet with augmented reality vision, a technology that can contribute to improving accuracy in certain surgical interventions.

In the operation, which thanks to the new technologies was accompanied by three other doctors in the United Kingdom, South Korea, and the United States, Grégory placed a prosthesis on the shoulder of an 80-year-old patient, a rather delicate procedure.

“It was as if the patient’s shoulder came to my eyes. All the help a doctor can expect in these conditions becomes reality, “said the surgeon, head of the orthopedic and orthopedic surgery and trauma department at the Avicenne Hospital in Bobigny, just outside Paris.

Equipped with a special helmet designed by the American company Microsoft, Grégory was able to visualize the patient’s skeleton and tendons in great detail thanks to a series of x-rays and other imaging tests performed before the operation.

Thanks to this device, surgery can be performed with millimetric precision, an important advantage in delicate procedures like the placement of prostheses.

In addition, those responsible for the experiment emphasized that the new technique minimizes the risk of infection.

The helmet allows the use of holograms representing different parts of the patient’s body and also determine the exact thickness of the tissues and the concrete site of nearby organs that remain invisible in a normal operation and therefore may be affected.

In addition, the doctor can consult the patient’s medical chart directly and even consult colleagues who accompany the operation in real time.

Grégory compared the “leap” that represents this technology with “the passage from the encyclopedia to the search engine of the internet,” because, thanks to the digital revolution, “limits human error .”

Image result for French doctor performs first surgery with augmented reality vision

“The technique will allow us to standardize this type of operation and thus reduce the risks,” said Grégory, who said that when its use becomes widespread “it will be the same as switching from aircraft in the Saint-Exupery era to current flights commercials “.

The doctor recalled that the success of some operations depends on “millimeters” and that the technology can also be applied in vascular surgeries in the brain, the most delicate.

Augmented reality technology is already used in military aircraft cabins and in some home electronic games.
