It may also be called a hypothermic reaction. An endothermic reaction is a chemical reaction in which energy (heat, light, etc.) is absorbed instead of being released as it is in a exothermic reaction. It may also be called a hypothermic reaction.
APL (named after the book A Programming Language) is a programming language developed in the 1960s by Kenneth E. Iverson. Its central datatype is the multidimensional array. It uses a large range of special graphic symbols to represent most operators, leading to very concise code.
The BCL-2 homolog BCL-X L, one of the two protein products of BCL2L1, has originally been characterized for its prominent prosurvival functions. Similar to BCL-2, BCL-X L binds to its multidomain proapoptotic counterparts BAX and BAK, hence preventing the formation of lethal pores in the mitochondrial outer membrane, as well as to multiple BH3-only proteins, thus interrupting apical proapoptotic signals.
