Phosphatidic acid is administered orally to increase muscle mass and strength in exercising mammals. Phosphatidic acid is administered orally to aging, bedridden or cachectic patients to improve nitrogen balance. The preferred form of phosphatidic acid for administration is phosphatidic acid-enriched lecithin. Creatine is co-administered orally to increase the muscle-building and strength effect. Other suggested additives include nutritional and herbal supplements, micronutrients and hormones.

Method for increasing muscle mass and strength

The present invention relates to a process for the preparation of a polysaccharide composed of D-xylose units of formula (III) linked together via beta 1,4 glycosidic bonds wherein Ris hydrogen or acetyl, Ris hydrogen, acetyl or a 4-O-methyl glucuronic acid unit, wherein, when Ris a 4-O-methyl glucuronic acid unit, the Rgroup on the same saccharide unit is defined as G, wherein G is hydrogen or acetyl, and wherein the sugar unit at the reducing end of sun such polysaccharide is xylose, lyxose or xylulose, said process comprising the following steps: selective deacetylation of xylan extracted from beech wood; and isomerization of the selectively deacetylated xylan achieved in step or the following steps: isomerization of xylan extracted from beech wood; and selective deacetylation of isomerized xylan achieved in step. The process is useful for the preparation of pentosan polysulfate or pharmaceutically acceptable salts thereof for pharmaceutical use.

A process for the purification of L-&#x3b1;-glycerophosphorylcholine is described, wherein L-&#x3b1;-glycerophosphorylcholine is crystallized from DMSO or from a mixture of DMSO with at least another solvent, preferably selected from water, alcohol, halogenated solvents, ethers, esters and/or amides. Such a process allows to obtain L-&#x3b1;-glycerophosphorylcholine having a purity greater than 99.5%, preferably greater than 99.7%, even more preferably greater than or equal to 99.9%. A method for determining the purity of L-&#x3b1;-glycerophosphorylcholine is also described, comprising the elution of L-&#x3b1;-glycerophosphorylcholine through an HPLC column having an amino stationary phase, and subsequent detection of L-&#x3b1;-glycerophosphorylcholine itself, and any impurity thereof, by means of an Evaporative Light Scattering Detector type.

Process for the purification of L-&#x3b1;-glycerophosphorylcholine

Described herein is a process for the synthesis of azacitidine or decitabine, comprising the silylation of azacytosine in the presence of N,O-bis-trimethylsilyl-trifluoroacetamide. Such reaction is performed in an organic solvent, preferably aprotic, even more preferably selected from among dichloromethane, dichloroethane and/or acetonitrile. According to a further aspect of the process, 2 to 3 moles of N,O-bis-trimethylsilyl-trifluoroacetamide are used per mole of azacytosine, preferably from 2.2 to 2.5.
