According to a new research, led by Daniel J. Conklin, Ph.D., an assistant professor at the University of Louisville, electronic cigarettes may affect heart rate and function.
For the study, the scientists exposed healthy mice to electronic nicotine delivery systems (ENDS) for 9 minutes. In addition, the mice were exposed to smoke from traditional cigarettes with and without nicotine.
Having analyzed the received results, the authors of the study concluded that ENDS aerosols strongly affect cardiovascular function in mice. Also, the study revealed that the mice also showed an increased blood pressure.
A new study led by Dr. Hui Chen from the University of Technology Sydney, Australia, suggests that smoking during pregnancy can be a risk factor for cerebral palsy in offspring.
A team of researchers achieved their results by studying mice born to mothers that had been exposed to cigarette smoke before and during pregnancy. In the course of the study, the scientists tested motor skills of the mouse pups and discovered that they demonstrated movement issues similar to those that arise in cerebral palsy.
Dr. Hui Chen says: “However, the message for the public is if you want a healthy baby, you need to stop smoking long before you plan for the pregnancy.”
According to a new research, high doses of certain vitamins of group B connected to the increased risk of lung cancer in smoking men.
The study was conducted by the scientists from the Arthur G. James Cancer Hospital and Richard J. Solove Research Institute at the University Comprehensive Cancer Center (OSUCCC) in Columbus, USA, with the Fred Hutchinson Cancer Research Center in Seattle, USA, and National Taiwan University in Taipei.
The researchers reviewed data from 77,118 people between 2000 and 2002 when participants were aged from 50 to 76. Every person gave information concerning the use of vitamin B over previous 10 years.
Having analyzed the collected data, the researchers concluded that male smokers taking 20 mg of Vitamin B-6 daily for 10 years were 3 times more likely to go on to develop lung cancer, and those male smokers taking 55 mg of Vitamin B-12 daily for 10 years were about 4 times more likely to develop the condition.
A new French study suggests that regular pot smoking can be connected to a limited degree of vision impairment.
Scientists included 52 participants to their study, 28 of them were smoking pot regularly (at least 7 times a week).
In their study, researchers were trying to answer such questions: does marijuana affect the healthy functioning of retinal ganglion cells (RGCs), which are situated on the surface of the retina? These cells are responsible for receiving visual information.
The findings of the study suggest that regular pot smokers do appear to experience a slight delay in RGC signalling that can indicate impaired vision.
A new British research published in the journal Heart found that smokers under 50 have 8.5 times higher heart attack risk compared to former smokers and non-smokers of the same age group.
For the study, the researchers analysed data from more than 1,700 adult heart attack patients in northern England.
The results of the study indicated that current smokers tended to be a decade younger than former smokers or non-smokers when they experienced a heart attack. In general, current smokers had more than triple risk of heart attack compared to former smokers of non-smokers together.
