In all eukaryotic organisms, genetic material is stored in the cell nucleus in the form of DNA. In order to be used, this DNA is first transcribed into messenger RNA in the cell cytoplasm, then translated into protein with the help of ribosomes, small machines capable of decoding messenger RNA to synthesize the appropriate proteins. However, the speed with which this mechanism takes place is not uniform: it must adapt to allow the protein to adopt the right configuration. Indeed, a deregulation of the production rate leads to structural defects. The proteins, which are not correctly folded will aggregate, become unusable and often toxic for the cell. from Top Health News -- ScienceDaily https://ift.tt/3yytIR5 via IFTTT

As much as 90% of the risk of a heart attack, stroke, or peripheral arterial disease (PAD) can be explained by smoking, poor eating habits, lack of physical activity, abdominal obesity, high blood pressure, raised blood lipid levels, diabetes, psychosocial factors, or alcohol. These guidelines focus on atherosclerotic cardiovascular disease (CVD), which affects the arteries. As the inside of the arteries become clogged up by fatty deposits, they can no longer supply enough blood to the body. This process is the main cause of heart attacks, strokes, PAD and sudden death where arteries become completely blocked. The most important way to prevent these conditions is to adopt a healthy lifestyle throughout life, especially not smoking, and to treat risk factors. from Top Health News -- ScienceDaily https://ift.tt/3gIPQC2 via IFTTT

Cell phones and social media can also help teens cope with stressful events -- as long as they strike the right balance between spending time online and pursuing other coping activities. from Top Health News -- ScienceDaily https://ift.tt/3zaFAK2 via IFTTT

A recent study led by an entomologist explores the different kinds of cells that make up mosquito immune systems. The research could shed light on how mosquitoes transmit malaria. from Top Health News -- ScienceDaily https://ift.tt/3kmZaN6 via IFTTT

Carnivorous animals lack key genes needed to detect and respond to infection by pathogens, a study has found. Farming large numbers of carnivores, like mink, could allow the formation of undetected 'disease reservoirs', in which a pathogen could spread to many animals and mutate to become a risk to human health. from Top Health News -- ScienceDaily https://ift.tt/3zdVuDx via IFTTT

Researchers found that first-year college students do pack on pounds, but implementing healthy patterns early can help stave off that weight gain. from Top Health News -- ScienceDaily https://ift.tt/3DgkE6M via IFTTT

Viruses do not always kill the cells they infect. Researchers have discovered in experiments with mice that cells have the power to self-heal and eliminate viruses. However, these cells undergo long-term changes. The findings may provide a hint as to why cured hepatitis C patients are more susceptible to liver cancer for years after. from Top Health News -- ScienceDaily https://ift.tt/2XI22wb via IFTTT

Among adolescents ages 10 to 14 in the U.S, the overall rate of drug use remained relatively stable in the first six months of the COVID-19 pandemic. However, one change was a decreased use of alcohol, but an increased use of nicotine and misuse of prescription drugs. from Top Health News -- ScienceDaily https://ift.tt/3mzLLUJ via IFTTT

Females and males differ in many ways and yet they share the same genome. The only exception is the male Y chromosome. Using beetles as a study system, new research shows that despite of the Y chromosome containing very few genes, it can dramatically change male body size and thus facilitate the evolution of sex differences. from Top Health News -- ScienceDaily https://ift.tt/3sJdIKu via IFTTT

The potential protective effect of sirtuin enzymes in age-related diseases, including cardiovascular diseases, remains an area of intense investigation. Now, researchers has determined that sirtuin 1 (SIRT1) and sirtuin 3 (SIRT3) levels decline in aging hearts, disrupting the ability of cardiac muscle cells (cardiomyocytes) to contract in response to ischemia-reperfusion injury. from Top Health News -- ScienceDaily https://ift.tt/3motZUe via IFTTT

While doctors have used low-intensity ultrasound as a medical imaging tool since the 1950s, experts are now using and extending models that help capture how high-intensity focused ultrasound (HIFU) can work on a cellular level. from Top Health News -- ScienceDaily https://ift.tt/3sKf5IQ via IFTTT

A study in more than 30,000 heart patients shows that becoming active later in life can be nearly as beneficial to survival as continued activity. from Top Health News -- ScienceDaily https://ift.tt/3Dd1ejh via IFTTT

Researchers have reversed lung fibrosis in a mouse model of idiopathic pulmonary fibrosis. Mice were given bleomycin for 12 days to establish lung fibrosis, and then treated daily until 21 days with ABT-199, whose medical form is known as Venetoclax, a medication approved by the United States Food and Drug Administration for use in several forms of leukemia. Control bleomycin mice had lung fibrosis with widespread collagen deposition. The bleomycin mice that received ABT-199 had normal lung architecture at 21 days and no collagen deposition. These results suggest a novel therapeutic target to reverse fibrotic remodeling in the lungs. from Top Health News -- ScienceDaily https://ift.tt/2UOr1Nu via IFTTT
