The heliopause is the theoretical boundary where the Sun's solar wind is stopped by the interstellar medium; where the solar wind's strength is no longer great enough to push back the stellar winds of the surrounding stars. This is the boundary where the interstellar medium and solar wind pressures balance. The crossin...

Initial attempts at dietary therapy in ALD involved restricting the intake of very-long chain fatty acids (VLCFA). Dietary intake is not the only source for VLCFA in the body, as they are also synthesized endogenously. This dietary restriction did not impact the levels of VLCFA in plasma and other body tissues. After t...
