Hookah is safer than cigarette – a pretty common myth!
Smoking hookahs is more harmful than traditional cigarettes, say scientists who found that puffing the water pipe for just half an hour can lead to the development of cardiovascular risk factors. The study by researchers at University of California, Los Angeles (UCLA) in the US is a direct contradiction to marketing efforts claiming that hookah smoking is less hazardous to health than cigarettes. Researchers measured heart rate, blood pressure, arterial stiffness, blood nicotine and exhaled carbon monoxide levels in 48 healthy, young hookah smokers before and after 30 minutes of hookah smoking. The study showed that a single session of hookah smoking increased heart rate (by 16 beats per minute) and blood pressure; and significantly increased measures of arterial stiffness, a key risk factor in the development of cardiovascular conditions such as heart attack or a stroke. The increase in arterial stiffness was comparable to data seen from cigarette smokers after smoking a cigarette.
Bacteria can sense amino acids
A new study has concluded that bacteria can sense amino acids and regulate their metabolism in response to the available nutrients. Researchers at the University of Leicester said that gathering knowledge about such bacteria could help in the development of drugs and antibiotics to combat a range of diseases, including tuberculosis. They have identified functions of a specific protein (Kinase G) that allow groups of bacteria such as Mycobacterium tuberculosis to detect amino acids in their surroundings, allowing the bacteria. This protein is found in a large and important group of bacteria that includes the causative agent of tuberculosis in humans.
Acting can help improve memory
Have you ever felt annoyed with yourself, maybe for forgetting to do an important task, or for leaving the house keys behind? If so, acting out things you are supposed to remember or pretending that you are actually doing it, can help you recall, suggests a research. The findings showed that alternative enactment techniques, such as acting, can improve patients’ prospective memory — where you have not remembered to take the action you had planned. This involves recreating an action one would like to remember, and pretending that you are actually doing it, in as much vivid detail as possible, the researchers said. A failing prospective memory can be an early sign of Alzheimer’s disease, according to lead author Antonina Periera, psychologist at the University of Chichester in the UK.
