Relapsing MS occurs when symptoms show up from time to time. Gilenya is in a class of drugs known as sphingosine I-phosphate receptor modulators, which work by keeping immune cells in the lymph nodes, so they can't reach and damage the brain or spinal cord.elapsing MS occurs when symptoms show up from time to time.

Answer: An ultrasound is the least invasive way to find out if you are having a boy or a girl. It is best done during the 18-22nd weeks of your pregnancy.
Most patients undergo an ultrasound at around 18-20 weeks (about four and a half to five months). Normally, at this stage of pregnancy we can determine the baby's sex, but not always. The position of the baby during the ultrasound is the most important aspect in our ability to tell the baby's sex, andthere's no way to influence that. For obvious reasons, it's usually easier to see if the baby is a boy. One reliable method is using amniocentesis to check the baby's chromosomes. This test is usually performed on a mother who is 35 years or older, for the purpose of identifying possible genetic problems.
