Ph. Eur. testing for histamine and depressor substances using guinea-pigs and cats: the end of an era. Strategy for removal of animal tests for histamine and depressor substances and their vestiges from the Ph. Eur.

For more than 50 years, assays have been used for testing pharmaceutical product safety due to their assumed ability to broadly detect potential unidentified contaminants. As part of these in vivo tests, the animal tests for depressor substances and histamine have been described in the European Pharmacopoeia since its first edition in 1977. Both tests measure the effect of histamine and histamine-like substances, using guinea-pigs and cats respectively.

Informal investigation on the added value of a potential certification system for the qualification of raw materials for the production of ATMPs.

The manufacture of advanced therapy medicinal products (ATMPs) is critically impacted by the quality of the raw materials (RMs) used. Following the need expressed by stakeholders to establish a certification scheme for biological RMs used in the manufacture of ATMPs, the European Pharmacopoeia (Ph. Eur.

European Pharmacopoeia's Approach to Cell and Gene Therapy: Focus on How Gene Therapy Texts Are Evolving.

The European Pharmacopoeia (Ph. Eur.) constitutes single recognised common standard for the quality control of medicines in Europe, which is also applied in many countries worldwide.

Replacement, Reduction, Refinement - Animal welfare progress in European Pharmacopoeia monographs: activities of the European Pharmacopoeia Commission from 2007 to 2017.

Since the opening for signature of the European Convention for the Protection of Animals Used for Experimental and Other Scientific Purposes in 1986, the European Pharmacopoeia Commission and its experts have carried out a programme of work committed to Replacing, Reducing and Refining (3Rs) the use of animals for test purposes. While updates on achievements in the field of the 3Rs are regularly provided, this article summarises the activities of the Ph. Eur.

Structures and Activities of the Elongator Complex and Its Cofactors.

Elongator is a highly conserved eukaryotic protein complex consisting of two sets of six Elp proteins, while homologues of its catalytic subunit Elp3 are found in all the kingdoms of life. Although it was originally described as a transcription elongation factor, cumulating evidence suggests that its primary function is catalyzing tRNA modifications. In humans, defects in Elongator subunits are associated with neurological disorders and cancer.
