Mefloquine in the geographic region visited. It is typically taken for one to two weeks before entering an area with malaria. Doxycycline and atovaquone/proguanil provide protection within one to two days and may be better tolerated. If a person becomes ill with malaria despite prophylaxis with mefloquine, the use of halofantrine and quinine for treatment may be ineffective. Mefloquine is used as a treatment for chloroquine-sensitive or resistant "Plasmodium falciparum" malaria, and is deemed a reasonable alternative for uncomplicated chloroquine-resistant "Plasmodium vivax" malaria. It is one of several drugs recommended by the United States' Centers for Disease Control and Prevention. It
Treatment of equine lameness cells may be harvested from other horses ahead of time to have banked for immediate treatment of an injury, but there is some concerns of graft-vs-host disease. Stem cells have been used to treat a variety of injuries in horses. The most research has been performed on stem cells used for treatment of tendon and meniscal injuries. Horses with tendonitis treated with bone marrow derived stem cells had a significantly lower re-injury rate compared to those without treatment. Stem cell treatment in damaged tendons is thought to improve the collagen make-up of the tendon while healing. It has been shown
