More than 40 billion capillaries—tiny, hair-like blood vessels—are tasked with carrying oxygen and nutrients to the far reaches of the human body. But despite their sheer number and monumental importance to basic functions and metabolism, not much is known about their inner workings.
Drug overdose is now the leading cause of death for individuals under the age of 50, as the opioid epidemic continues unabated. One reason is that the majority of the estimated 2.4 million Americans with opioid use disorder aren't getting evidence-based treatment, including medications to treat opioid addiction.
Making healthy food easier to access in hospital canteens and food outlets, as well as increasing healthy options and reducing portion sizes, are the most effective ways of encouraging healthcare staff to improve their diets according to a new study from the University of Warwick. Using 'nudge theory', which has been shown to encourage healthy eating in other settings, these low-cost changes could have a significant effect on improving the health of the workforce of the NHS.
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. However, a new study in sheep, publishing in the open-access journal PLOS Biology, by a team from Cambridge University, finds that offspring whose mothers had a complicated pregnancy may be at greater risk of heart disease in later life, suggesting that our cards may be marked even before we are born.
Cancer of the esophagus claims more than 400,000 lives around the world each year. With no efficient, reliable method of screening for the disease, by the time symptoms become apparent, it's often too late to save the patient. A Johns Hopkins researcher who has devoted his career to the detection and prevention of esophageal cancer today published a paper in the journal Clinical Cancer Research that he says could finally result in simple and inexpensive screening for the deadly disease.
The reader is also introduced to the different thyroid nodule risk stratification systems in ultrasound imaging, when and how to perform thyroid fine needle aspiration biopsies, and the use of percutaneous ethanol injections for cystic thyroid nodules.
Should healthy people take aspirin to ward off heart disease ? The notion has been controversial, and the medical advice mixed. But if you think that there are any benefits, it would be slight, and they would be counterbalanced by a matching rise in bleeding risks.
Clinicians can more accurately identify children with cellulitis who need IV antibiotic administration using a score that includes the child’s systemic features, swelling, eye involvement, tenderness, and whether the condition affects 1% or more of the child’s body.
Researchers studying ancient corncobs found at a Native American archeological site have recovered a 1,000-year-old virus, the oldest plant virus ever reported. Only a few RNA viruses had been discovered previously from archaeological samples, the oldest dating from about 750 years ago. The new discovery came as the research team examined ancient plant material from Antelope House, an Ancestral Puebloan ruin located at Canyon de Chelly National Monument, Arizona.
Macroalgae have been reported as an important source of halogenated aromatic secondary metabolites, being the majority of these derivatives isolated from red algae. Halophenols and haloindoles are the most common haloaryl secondary metabolites isolated from these marine organisms. Nevertheless, some halogenated aromatic sesquiterpenes and naphthalene derivatives have also been isolated.
