Tokyo researchers reveal key role of Fen1 in resisting antiviral and anticancer drug effects

Your weight loss plan should keep you healthy and strong as you lose the extra weight. Many plans include a diet low in carbohydrates. Carb cycling is a method of optimizing your carbohydrate intake to meet your needs while dieting, fasting, and working out. When you're carb cycling, you consume carbs to meet your needs on some days and avoid them on other days. The aim of carb cycling is to consume carbohydrates when your body needs them and exclude them at other times. Such strategies in your diet plan can help your weight loss efforts. Carbohydrates, or carbs, are a significant part of the average human diet. Along with proteins and fats, they make up the bulk of your daily meals. Most carbohydrates are broken down by your body into glucose to provide energy for your cells and tissues. Carbohydrates in your diet are of three types — sugars, starches, and fiber. Sugars are simple carbs. Glucose, sugar (sucrose), lactose found in milk, and fructose found in fruits, are naturally occurring sugars. Your body metabolizes these molecules rapidly to yield energy. Starches are complex carbs. They're large molecules that consist of hundreds of molecules of simple sugars joined together. Your body needs to break them down to release energy. Starches are found in bread, potatoes, peas, corn, cereals, and pasta. Fiber is also a complex carbohydrate. Human bodies can't break down these large molecules, so they provide no energy. They're usually excreted as they are in the feces. They add bulk to your meal, so you feel full. Fiber in the diet helps avoid constipation and lowers blood sugar and cholesterol levels. Carbohydrates are an essential part of your diet. A typical diet provides 45% to 65% of its calories from carbohydrates. If you have 2,000 calories a day, you should have about 275 grams of carbohydrates. Always try to choose healthy foods for your carb intake:

RAS mutations are one of the most common cancer-causing genetic mutations, and the drug is now being studied in several cancer types. I think it's going to work especially well in tumors that are primarily RAS driven, including colon cancer and lung cancer. It might also work in other cancer types in combination with drugs targeting other genetic mutations, but further research is needed.

Algae are photosynthetic aquatic creatures that grow through the consumption of nutrients, light, and carbon dioxide. They are a diverse group of creatures that include tiny single-celled algae and enormous kelp, as well as seaweed 1. Numerous prokaryotic and eukaryotic algae species are desirable food sources for humans due to their inherent qualities 2,3. Human intake of macroalgae such as seaweed and microalgae like phytoplankton dates back many years. Multicellular macroscopic aquatic plants, or macroalgae, are classified into three taxa: Phaeophyceae, or brown algae, Rhodophyta or red algae, and Chlorophyta or green algae. Microalgae, the unicellular counterpart of macroalgae, are categorized in a broader framework that includes prokaryotic cyanobacteria (blue-green algae), Euglenophyta, and Chlorophyta, which are genetically distinct from one another. The ancient populations of Chad and the Aztec culture were already familiar with the cyanobacteria spirulina, which is currently advertised as a superfood in the West 4. In Burma, Vietnam, and India, other cyanobacteria/microalgae, like Spirogyra and Oedogonium, were eaten as food or as a supplement 4. Seaweed is a staple of daily meals in many Asian and Pacific civilizations, including Korea, Japan, and Indonesia, as well as Hawaii and New Zealand 5.

One of the first ways in which this would be really felt by patients is through the repurposing of existing drugs for new diseases. Clearly, even though one could improve the process in a number of ways in terms of speeding up medicinal chemistry programs and potentially speeding up the amount of things such as toxicity trials etc., that is still going to take time. However, if we can take existing drugs, perhaps drugs which have gone off patent or are currently being marketed for another indication, and repurpose them in areas where there are high unmet medical needs, those drugs could go into that new indication in phase 2 in patients and you would know very quickly whether the drug worked or not. Then the route to market or the route to being able to make the drug more broadly available to patients would be much more rapid because you don't have to go through all those earlier stages of toxicity, testing, phase 1 testing, volunteers and so on.

AI is moving so quickly that in the gap between answering this and publication, I could be proved wrong! With that caveat, there is a lot of hype around AI drug discovery campaigns. AI is certainly a substantial part of many discovery programs today and has been applied in drug discovery for many years. However, we need to be realistic about what AI is doing, where humans remain central, and how that balance may vary. AI agents are an area that has emerged relatively recently and continues to evolve quickly. They can complete tasks for example data extraction and reporting with guidance from experts, helping to generate larger, more standardized datasets over time. They can also help build closed-loop systems that connect computation and experiment directly, with strategic direction still coming from expert scientists. However, care and oversight is needed with these systems to validate their actions. I also think people often equate AI with generative AI, but there are many other AI systems which are underappreciated. For example, the GNN property prediction models and task-specific predictive tools we discussed earlier can be extremely valuable. Some of these methods receive less attention simply because they have already become familiar in drug discovery.
