Genetic recombination and recombinational DNA repair also occurs in bacteria and archaea, which use asexual reproduction. Recombination can be artificially induced in laboratory (in vitro) settings, producing recombinant DNA for purposes including vaccine development.rom Wikipedia, the free encyclopedia. A current model of meiotic recombination, initiated by a double-strand break or gap, followed by pairing with an homologous chromosome and strand invasion to initiate the recombinational repair process.
Anti-reflux surgery is a treatment for acid reflux, also known as GERD (gastroesophageal reflux disease). GERD is a condition in which food or stomach acid come back up from your stomach into the esophagus.
Scientists found the death rate following so-called laparoscopic fundoplication surgery for gastroesophageal reflux disease, or GERD, was far lower than the 1 percent often quoted. Experts contended the surgery might be underutilized, especially in light of increasing safety concerns about acid reflux drugs. One of the main arguments against surgery when choosing between [drug] and surgical treatment for severe GERD is the risk of mortality, said study author Dr. John Maret-Ouda.
