Scientists from the University of South Florida in Tampa, USA, suggest that using betanin, a compound that gives dark red color to beetroots, can be used in future drugs to treat the Alzheimer’s disease.
To achieve their results, the team of researchers conducted a series of laboratoryexperiments during which they monitored the activity of amyloid beta in different context with the help of 3,5-Di-tert-butylcatechol (DTBC), a compound that allows the scientists to observe the process of oxidation.
Li-June Ming, one of the lead researchers of the study, says: “This is just a first step, but we hope that our findings will encourage other scientists to look for structures similar to betanin that could be used to synthesize drugs that could make life a bit easier for those who suffer from this disease.”
According to a recent research from the University of Manitoba, lentils in your meal may successfully fight high blood pressure, scientifically called hypertension.
The researchers also found that eating lentils can reverse declines in blood vessel health. The results of the study were presented at the annual conference of the American Heart Association, held in Dallas, USA.
Dr. Peter Zahradka, one of the lead authors of the two experiments on the effects of lentils, believes that the results are amazing. He also adds: “[The results] provide a non-pharmacological way of treating diseases associated with blood vessel dysfunction.”
A new study, published in the British Journal of Cancer, reveals that men who used to binge-watch TV-shows may have the higher risk of developing colorectal cancer.
For their study, a team of researchers analyzed data from UK Biobank, a health database of approximately 500,000 men and women in the United Kingdom. The scientists gathered data on how many hours each subject spent in sedentary activities such as TV-watching or using a computer daily.
Having analyzed the received results, the scientists concluded that men who watched TV at least 4 hours a day had a 35% greater risk of developing colorectal cancer than men who watched TV for 1 hour a day or less. Also, the researchers found that men who were engaged in higher levels of physical activity had 23% lower risk of developing colon cancer.
A new research by Rutgers University suggests that fiber may play a far more important role in nurturing the gut bacteria that control blood sugar and fat.
The researchers believe that this discovery could pave a new way to personalized high-fiber diets as the first-line treatment for type 2 diabetes. It also could help to curb rated of diabetes diagnosis. Foods containing lots of fiber boost gut bacteria that control blood sugar by breaking down carbohydrates.
Professor Liping Zhao, one of the researchers and a microbiologist at Rutgers University-New Brunswick in New Jersey, says: “Our study lays the foundation and opens the possibility that fibers targeting this group of gut bacteria could eventually become a major part of your diet and your treatment.”
Physical activity can not exclude all negative consequences caused by alcohol consumption, however, doing sports helps to reduce the risk of many diseases caused by excessive consumption of alcoholic beverages.
This conclusion was made by British specialists, and they believe that physical activity significantly reduces the risk of development of cancer and cardiovascular diseases due to alcohol abuse. According to experts, they carefully studied all the archival data for the period from 1994 to 2006 for Scotland and England. It turned out that people who abuse alcohol are more likely than others to develop many diseases, but this is provided if they have a sedentary lifestyle.
Scientists have found that people who have a sober lifestyle are the least likely to die prematurely, but those who exceed the weekly alcohol limit by several units, but regularly do sports are also included in this group. Experts stressed that people who drink two or four times a week can exclude themselves from the risk group if they devote lessons in the gym or jogging about two to three hours a week.
Approximately 80% of the male population of the entire planet experiences constant pain in the back. The reason for this are not correct posture formed in childhood and the lack of constant exercises, without which the muscles simply do not have enough strength to support the body. Fortunately, the problem can be solved without medication. It will be enough to work regularly in the gym. However, not all exercises will affect the sick back in a fertile way. There are five best workouts that will not only strengthen the muscles, but also help get rid of the old problem.
- Pulling up with a wide grip. You will not manage to get rid of back pain without pull-ups. This exercise involves the widest muscles of the back – this training help to become slimmer even to those who could not defeat bad posture from childhood. The main thing is to remember: repetition is done slowly, with control at all stages; the right grip is slightly wider than the shoulders.
- Pull-down. The bonus of this exercise is an increased growth of muscle mass. Pull-downs make the whole body work: the legs stabilize the body, and the hands are busy with a specific load. Do the exercise with full efficiency, otherwise it will lose half of its usefulness. Capture – on the width of the shoulders, the movement down does not involve the body, pulling is carried out from the activities of the shoulders back and down. Do not forget to take a short pause at the end point.
- Dead-lift. It is very important to perform the dead lifting correctly. Jerks, wrong setting of feet, haste – the easiest way to get a serious back injury. But if you do everything right, the dead lift will turn into the best exercise for the whole body. Maintain a natural deflection in the lower back. Capture – on the width of the shoulders. Pull the body up, while pushing the hips slightly forward. The end point is a short pause and a smooth return of the rod to its starting position.
- Dead lift in slope. The static version of the dead lift is less traumatic and more accentuated on the muscles of the back. Starting position: the body is bent almost parallel to the floor. Capture – is slightly wider than the shoulders, straight. Raise the barbell, straining the lateral and middle muscles.
- Rowing on the simulator. Sit down on the bench of the cable simulator. Capture is usual, slightly wider than shoulders. Pull the crossbar to the top of the abdomen. Returning to the starting position, slightly bend forward – so you will give the muscles a stimulating stretching.
Spinach is loaded with vitamins and minerals and can be an excellent addition to your diet. Of course only in case if you cook it right.
Registered dietitian Samara Abbot explains: “Boiling vegetables can cause a loss in water-soluble vitamins. So you won’t get as much vitamin C and folate as you would if you’d just eaten a raw spinach salad. Raw spinach is not considered to be the best calcium source because it also contains oxalic acid, which prevents calcium absorption.”
However, there are some ways of cooking spinach that will allow you to get both vitamin C and calcium. Nutritionists suggest steam or microwave spinach in order to get more nutritional value in every gram of the vegetable. Spinach cooked like this can be added to smoothies, soups or omelets.
A new study, conducted by the researchers from the University of Wisconsin-Madison and Bar-Ilan University, suggests that different smiles may reduce or increase physical stress depending upon how they are perceived.
A team of scientists measured levels of cortisol in the saliva of 90 male undergraduate students. The researchers found that “dominance” smiles were associated with higher HPA axis activity, such as increases in heart rate and salivary cortisol.
The researchers write in their paper: “The findings provide further evidence for the view that smiles do not necessarily constitute positive nonverbal feedback, and that they may impact social interactions by affecting the physiological reaction of people who perceive them. In addition, cortisol appears to support the detection of social threat and coordinate biological activity needed to adequately respond to the threat.”
A recent study from a Kaiser Permanente suggests that eating fatty fish once a week may help decrease the risk of developing multiple sclerosis (MS) by 45%. This means that changes in diet may help prevent the condition.
For the study, a team of researchers asked 1,153 people about fish they ate, how often they had fish, and whether they took any fish oil supplements. Approximately half of the patients had been diagnosed with one of the forms of MS, first or recurring.
Study author Dr. Annette Langer-Gould of Kaiser Permanente Southern California and a member of the American Academy of Neurology explains: “We wanted to see if this simple lifestyle modification, regularly eating fish and taking fish oil supplements, could reduce the risk of MS.”
A new study, conducted by the RNA Molecular Biology Laboratory at the Faculty of Sciences and ULB-Cancer Research Center, suggests that a natural extract from daffodils may have cancer-killing properties. The results of the study show the mechanism by which the plants of the family Amaryllidaceae alkaloids can fight cancer.
The researchers show that hemanthamine (HAE) inhibits protein production by acting on these ribosomes. The extract seems to block the production of ribosomes in the so-called nucleolus.
The authors of the study explain in their paper: “Their biological activities are not restricted to anticancer effects but include potential anticholinesterase, antimalarial, antiviral, and anti-inflammatory effects. Also, the authors conclude that they provide a rationale for designing molecules with enhanced potencies and reduced toxicities.
A new study from Rush University in Chicago, US, suggests that eating fruits, vegetables, and whole grains reduces people’s risk of developing depression by more than 10%.
For the study, a team of researchers analyzed 964 people whose average age was 81 years every 12 months for approximately six and a half years. The participants of the research have been monitored for symptoms of depression.
Study author Dr. Laurel Cherian says: “Making lifestyle changes such as changing your diet is often preferred over taking medications, so we wanted to see in diet could be an effective way to reduce the risk of depression.”
According to a Spanish research, led by Dr. Victoria Moreno-Arribas from the Spanish National Research Council in Madrid, drinking red wine may protect teeth by destroying bacteria causing cavities and gum disease.
The researchers completed an experiment where they tested concentrations in the range normally found in wine – 50 and 10 µg/ml. While working with cells that modeled gum tissue, the researchers have found the two wine polyphenols, caffeic and p-coumaric acids, were generally better than the total wine extracts at cutting back on the bacteria’s ability to stick to the cells.
Results of the study also suggest that antioxidants in red wine are more efficient than grape-seed and red-wine extracts at preventing plaque-causing bacteria from sticking to lab-grown cells in modeled gum tissue.
