Abstract: The present invention relates to a selective catalytic reduction catalyst for the treatment of an exhaust gas of a combustion engine, the catalyst comprising a substrate comprising an inlet end, an outlet end, a substrate axial length extending from the inlet end to the outlet end and a plurality of passages defined by internal walls of the substrate extending therethrough; a coating disposed on the substrate (i), the coating comprising a first non-zeolitic oxidic material comprising aluminum, an 8-membered ring pore zeolitic material comprising one or more of copper and iron, and a second non-zeolitic oxidic material comprising cerium and one or more of zirconium, aluminum, silicon, lanthanum, niobium, iron, manganese, titanium, tungsten, copper, molybdenum, neodymium, cobalt, chromium, tin and praseodymium; wherein at least 65 weight-% of the coating consist of the 8-membered ring pore zeolitic material comprising one or more of copper and iron.

Abstract: Provided herein is a catalytic article including a catalytic coating disposed on a substrate, wherein the catalytic coating comprises a bottom coating on the substrate and a top coating layer on the bottom coating layer, one such coating layer containing a platinum group metal on a refractory metal oxide support and the other such coating layer containing a ceria-containing molecular sieve. Such catalytic articles are effective toward treating exhaust gas streams of internal combustion engines and exhibit outstanding resistance to sulfur.

Abstract: This invention relates to the use of AMPK agonists, such as metformin to, restore the responsiveness of aged oligodendrocyte progenitor cells (OPCs) to differentiation factors. This may be useful in promoting oligodendrocyte differentiation and increasing the remyelination of neuronal axons, for example in the treatment of demyelinating diseases, such as multiple sclerosis (MS). Therapeutic combinations comprising AMPK agonist and a differentiation factor and therapeutic uses thereof are provided.

Abstract: A catalyst composition containing a molecular sieve containing palladium and ceria is provided, which exhibits outstanding sulfur resistance. The catalyst composition is suitable for treating an exhaust gas stream including hydrocarbons and/or carbon monoxide and/or Nox.

Abstract: A piston rod and a piston are installed with freedom of axial movement in a cylinder filled with a working medium, the piston dividing the working space into a space on the piston-rod side of the piston and a space on the side of the piston facing away from the piston rod. A stop disk is mounted on the piston rod in addition to the piston rests against a retainer provided on the cylinder to limit the outward movement of the piston rod during a fire.
