Malaria in pregnant women and infants, and in preschool children where transmission is seasonal. There are a number of medications that can help prevent or interrupt malaria in travelers to places where infection is common. Many of these medications are also used in treatment. In places where "Plasmodium" is resistant to one or more medications, three medications—mefloquine, doxycycline , or the combination of atovaquone/proguanil ("Malarone")—are frequently used for prevention. Doxycycline and the atovaquone/proguanil are better tolerated while mefloquine is taken once a week. Areas of the world with chloroquine sensitive malaria are uncommon. The protective effect does not begin immediately, and
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
