Rhinoplasty technique preserves ethnic identity
African Americans who underwent a nose job, also referred to as rhinoplasty, reported a high degree of satisfaction with the results.
Rhinoplasty was conducted using a three-tiered approach that included an adjustment in nasal height and angle with a reshaping of the tip and a reduction in the width of the nose.
Dr. Oleh Slupchynskyj and Marzena Gieniusz analyzed questionnaires completed by 75 African American patients who underwent the procedure at their private practice, the Aesthetic Facial Surgery Center of New York and New Jersey in New York City.
Internet, alcohol and sleep tied to girls’ weight
Girls and young women who devote much time to the Internet, get too little sleep or regularly drink alcohol are more likely than their peers to put on excess weight, a new study suggests.
The researchers, who followed more than 5,000 girls between 14 and 21 years old for 1 year, found that the more spare time girls spent on the Internet, the more their body mass index (BMI) increased.
Similar patterns were seen when the researchers looked at alcohol consumption and sleep. In the latter case, lack of sleep was linked to greater gains in BMI—a measure of weight in relation to height.
EU says safety of cloned animal products uncertain
The European Union’s top food safety agency said on Thursday cloned animal products may not be safe and further study was needed.
“It is clear there are significant animal health and welfare issues for surrogate mothers and clones that can be more frequent and severe than for conventionally bred animals,” Vittorio Silano, chair of EFSA’s Scientific Committee, told reporters.
“For cattle and pigs, food safety concerns are considered unlikely. But we must acknowledge that the evidence base is still small. We would like to have a broader data base and we need further clarification.”
Soy-based foods may lower sperm count: study
Eating a half serving a day of soy-based foods could be enough to significantly lower a man’s sperm count, U.S. researchers said on Wednesday.
The study is the largest in humans to look at the relationship between semen quality and a plant form of the female sex hormone estrogen known as phytoestrogen, which is plentiful in soy-rich foods.
“What we found was men that consume the highest amounts of soy foods in this study had a lower sperm concentration compared to those who did not consume soy foods,” said Dr. Jorge Chavarro of the Harvard School of Public Health in Boston, whose study appears in the journal Human Reproduction.
Kelsey Grammer nearly died after heart attack
Television star Kelsey Grammer, best known from “Cheers” and his sitcom “Frasier,” nearly died after suffering a heart attack last month, he told U.S. showbiz news program “Entertainment Tonight.”
Grammer, 53, felt chest pains while paddle-boarding with his wife in Hawaii, where they have a second home, and was taken to hospital, where he was found to have suffered a heart attack.
At the time, about seven weeks ago, his spokesman Stan Rosenfield said it was a mild heart attack but declined to give further details of Grammer’s condition or medical treatment.
New study of gene evolution could lead to better understanding of neurodegenerative disease
Genetic evolution is strongly shaped by genes’ efforts to prevent or tolerate errors in the production of proteins, scientists at The University of Texas at Austin and Harvard University have found.
Their study also suggests that the cost of errors in protein production may lie in the malformed proteins themselves, rather than in the loss of functional proteins. Misfolded proteins can build up in long-lived cells, like neurons, and cause neurodegenerative diseases.
The work, by Claus Wilke at The University of Texas at Austin and D. Allan Drummond at Harvard, is described in the July 25 issue of the journal Cell.
Mate or hibernate? That’s the question worm pheromones answer
If worms could talk, they might tell potential suitors, “I like the way you wriggle,” complete with that telltale come slither look. But worms send their valentines via signals known as pheromones, a complex chemical code researchers are now cracking, according to a study published Wednesday (July 23) in the journal Nature.
Scientists from the University of Florida, Cornell University, the California Institute of Technology and the U.S. Department of Agriculture have discovered the first mating pheromone in one of science’s most well-studied research subjects, the tiny worm Caenorhabditis elegans. But perhaps even more interesting is what the newly discovered pheromone also directs worms to do — hibernate.
At lower levels, the pheromone signals the male C. elegans to mate with its partner. But when the worm population grows and the food supply dwindles, the chemical signal increases and the cue changes from mate to hibernate. This discovery could help researchers find ways to combat more harmful worms that destroy crops and provide clues for scientists studying similar parasite worms, said Arthur Edison, Ph.D., a UF associate professor of biochemistry and molecular biology in the College of Medicine and one of the study’s senior authors.
