Enzyme that breaks down amino acids plays key role in promoting cellular senescence

Permanently arrested cell growth is known as "cellular senescence", and the accumulation of senescent cells may be one cause of aging in our bodies. Japanese researchers have discovered that a certain enzyme in our bodies promotes cellular senescence by producing reactive oxygen species.

Study demonstrates beneficial effects of influenza vaccination on COPD patients

A new study published in the January issue of CHEST establishes that patients with chronic obstructive pulmonary disease face heightened risks of death, critical illness, and hospitalization if they develop the flu and demonstrates the beneficial effects of influenza vaccination.

Cardiovascular disease risk begins even before birth

Heart disease is the greatest killer in the world today, and it is widely accepted that our genes interact with traditional lifestyle risk factors, such as smoking, obesity and/or a sedentary life to promote an increased risk of cardiovascular disease.

Nicotinamide riboside supplementation confers significant physiological benefits to mothers and offspring

ChromaDex Corp. today reported that results of a first-of-a-kind preclinical study on lactation have shown that supplementation with the unique B3 vitamin nicotinamide riboside confers significant and enduring physiological benefits to mothers and offspring.

Researchers create new micro-dispenser for storage and controlled release of liquids

Lab-on-a-chip technology could transform medicine in ways comparable with how microprocessors have changed our everyday lives - that is once it can be manufactured in a scalable cost-effective way. Researchers in Sweden now report a development that could speed this revolution up.

Synthetic compound from flaxseed can improve heart function in mice with sepsis

Sepsis is a life-threatening systemic inflammatory condition that develops in response to infection. One of its major complications is cardiovascular dysfunction, in which deterioration of the heart muscle, driven by decreased energy production resulting from reduced oxygen and nutrient supplies, frequently ends in organ failure.

Graphene Flagship project studies impact of graphene and related materials on our health

As the drive to commercialize graphene continues, it is important that all safety aspects are thoroughly researched and understood.

Placenta adapts and compensates when pregnant mothers have poor diets or low oxygen

Cambridge researchers have discovered the placenta regulates how much oxygen and nutrients it transports to babies during challenging pregnancies in a study using mice to model conditions in the womb.

Poor blood oxygenation during sleep predicts chance of heart-related death

Elderly men who experience extended episodes of interrupted breathing while asleep have a high risk of heart problems. Research shows for the first time that poor blood oxygenation is a good indicator of the chance of heart-related death, which cannot be attributed to sleep apnoea alone.

Study: Over 5.6 million Americans exposed to high nitrate levels in drinking water

More than 5.6 million Americans are potentially exposed to nitrate in drinking water at levels that could cause health problems, according to a new study. In this first analysis of its kind, researchers found that water systems with higher nitrate levels also tend to serve communities with higher proportions of Hispanic residents.

Innovative ‘light’ method demonstrates positive results in fight against malignant tumors

A team of scientists from the National University of Science and Technology "MISIS", the Moscow Technological University and the Pirogov Russian National Research Medical University has experimentally proved the effectiveness of the formerly suggested "light" method in oncotherapy.

Blood vessels can now be created perfectly in a petri dish

Researchers have now successfully created perfect blood vessels in the labs and this may be a huge step in benefitting people with diabetes and other conditions. The report of the procedure appears in a study titled, “Human blood vessel organoids as a model of diabetic vasculopathy,” published in the latest issue of the journal Nature.

Researchers describe new behavior in energy metabolism that refutes existing evidence

Researchers from the Catalonian Institute of Bioengineering and the Seville Chemical Research Institute have described a new method for the transmission of electrons between proteins that refutes the evidence from experiments until now.

Research finds decline in ketone body utilization when coronary circulation is reduced

Ketone bodies are metabolites that can be used as energy sources like glucose and fatty acids. They can be converted into acetyl-CoA, which produces energy via the Krebs cycle in the mitochondria, and are typically used as an alternative energy source during starvation, fasting, or periods of high-intensity exercise.

Poor cardiorespiratory fitness could increase risk of future heart attack, finds new study

Poor cardiorespiratory fitness could increase your risk of a future heart attack, even if you have no symptoms of a lifestyle illness today, a new study has found.

Researchers cultivate vascular organoids that perfectly mimic human blood vessels

For the first time, researchers have successfully cultivated “vascular organoids” in a petri dish that perfectly mimic real human blood vessels.

New conservation practice could reduce nitrogen from agricultural drainage, study shows

Every summer, a "dead zone" forms in the Gulf of Mexico. Plumes of oxygen-robbing algae, fed by excess nitrogen coming in from the Mississippi River, kill off marine life and threaten the livelihoods of those who fish the Gulf. States bordering the Mississippi River are putting strategies in place to limit nitrogen from wastewater treatment plants, surface runoff, and agricultural fields.

Researchers reveal how fasting leads to better overall health

In a University of California, Irvine-led study, researchers found evidence that fasting affects circadian clocks in the liver and skeletal muscle, causing them to rewire their metabolism, which can ultimately lead to improved health and protection against aging-associated diseases.
