Openhelix (una risorsa importante per il bioinformatico)

La Newsletter del Bioforum mi fa notare l’apertura di un nuovo blog : OPENHELIX focalizzato su genomica e risorse bioinformatiche.
Secondo le intenzioni degli autori il blog dovrebbe essere uno strumento per rimanere aggiornati riguardo i cambiamenti delle risorse presenti in rete e i vari database genomici. MA NON SOLO. Il blog è strutturato in modo che, insieme ai post quotidiani, viene messo a disposizione, di solito al mercoledì, un “TIP of the WEEK“, ovvero un breve video di circa 4 minuti che descriva, all’uso pratico, come ottenere il meglio dai database disponibili, sottolineando nuove funzioni, o metodologie per estrarre informazioni “nascoste“.

Certo è che, nei Tips vi sono dei tutorial ottimamente fatti. La qualità è veramente elevata!
Ma non è tutto: insieme ai Tips, settimanalmente verra’ proposto un’area “What’s Your Problem?”, dove il lettore potrà proporre quesiti e aspettarsi quindi risposte competenti riguardo per esempio come poter estrarre le informazioni che gli servono da una specifica risorsa. Una specie di help desk personalizzato.
Vi lascio infine immaginare il contenuto di un’ultima sessione, chiamata “Guest Post:-)

Personalmente seguo con avidità questa nuova risorsa, e non mancherò di sottoporvi alcuni loro Tips che reputo di particolare interesse. Eccovi intanto il loro feed principale. Sono sicuro che questo nuovo blog – se mantiene le promesse – diventerà sempre più una risorsa indispensabile!

heart health supplements to take

Confused or overwhelmed about supplements? Your doctor can help you find the right combination.

Our modern world can bring overwhelming amounts of information aimed at helping us get healthier through supplements. Often, some people will see improvements, while others won’t. Here are some supplements that can help boost the effects of healthy diet and exercise for your precious heart, and one supplement to avoid.

In the United States, dietary supplements are substances you eat or drink. They can be vitamins, minerals, herbs or other plants, amino acids (the individual building blocks of protein), or parts of these substances. They can be in pill, capsule, tablet, or liquid form. They supplement (add to) the diet and should not be considered a substitute for food.  These are just some of the healthy benefits that biofit provides.

Click the name of each supplement to see more information, including results from studies, showing uses and doses. You can share this information with your doctor to find the right supplements for you.

1. Multivitamin & mineral

Vitamins and minerals taken in appropriate doses may aid in lowering heart disease risk. Whole foods should be the main source of nutrients, and research shows that many people fall short of recommended intakes.

A supplement can’t make up for unhealthy eating habits, but sometimes even people who have healthy eating habits find it hard to get all the fruits, vegetables, and other healthy foods they need. A supplement can help fill in the gaps.

Numerous studies suggest positive association between taking vitamin and mineral supplements, and heart disease prevention. Vitamin and mineral supplements can be safe and inexepensive and may provide a health benefit.

2. Coenzyme Q10 (Co Q10)

Coenzyme Q10 (CoQ10) is a substance similar to a vitamin. It is found in every cell of the body. Your body makes CoQ10, and your cells use it to produce energy your body needs for cell growth and maintenance. It also functions as an antioxidant, which protects the body from damage caused by harmful molecules. CoQ10 is naturally present in small amounts in a wide variety of foods, but levels are particularly high in organ meats such as heart, liver, and kidney, as well as beef, soy oil, sardines, mackerel, and peanuts.

Coenzymes help enzymes work to help protect the heart and skeletal muscles.

CoQ10 is also said to help heart failure, as well as boost energy, and speed recovery from exercise. Some people take it to help reduce the effects certain medicines can have on the heart, muscles and other organs.

3. FiberThe best way to get fiber is from food. However, if you don’t include enough fiber-rich food in your diet and choose to use a fiber supplement, choose a product that has different types of fiber in it-both soluble and insoluble. When taking a fiber supplement, be sure to stay well hydrated.

Psyllium fiber may help lower cholesterol when used together with a diet low in cholesterol and saturated fat.

If you choose to take a fiber supplement, be sure you don’t inadvertently purchase a laxative supplement instead. The labels on both types of supplements may say something like “regulates bowel patterns.”

Fiber seems to be most effective used in conjunction with diet and exercise for contributing to weight loss.

4. Omega-3 fatty acids

Omega-3 polyunsaturated fatty acids are found in oil from certain types of fish, vegetables, and other plant sources. These fatty acids are not made by the body and must be consumed in the diet or through supplements, often “fish oil.”

Omega-3 polyunsaturated fatty acids work by lowering the body’s production of triglycerides. High levels of triglycerides can lead to coronary artery disease, heart disease, and stroke. Omega-3 polyunsaturated fatty acids used together with diet and exercise help lower triglyceride levels in the blood.

In a double-blind study of patients with chronic heart failure, supplementation with fish oil resulted in a small but statistically significant decrease in the number of patients who died or were hospitalized for cardiovascular reasons. In another double-blind trial, supplementation improved heart function and decreased the number of hospitalizations in some patients. Get the best results with synogut.

5. Magnesium

Low magnesium levels can be a predictor of heart disease, research has revealed. Low magnesium has been linked with cardiovascular risk factors such as: high blood pressure, arterial plaque build-up, calcification of soft tissues, cholesterol and hardening of the arteries.

Magnesium supplements come in various forms and mineral combinations, such as magnesium citrate , magnesium gluconate, magnesium hydroxide and the popular form of magnesium sulfate , also known as Epsom salt, used in baths and foot soaks for sore, tired muscles.
