Cutaneous ulceration as a presenting feature of type 1 lepra reaction: A case report.

Reactions in leprosy represent sudden shift in the immunological response and are seen in 11-25% of affected patients. It can be seen before, during or after the completion of multidrug therapy (MDT). Two types of reactions are recognized; Type 1 reaction (T1R), seen in borderline leprosy, affecting mainly skin and nerves; type 2 reaction (T2R) or erythema nodosum leprosum (ENL), seen in lepromatous leprosy, characterized by systemic features in addition to cutaneous lesions.

ValidatorDB: database of up-to-date validation results for ligands and non-standard residues from the Protein Data Bank.

Following the discovery of serious errors in the structure of biomacromolecules, structure validation has become a key topic of research, especially for ligands and non-standard residues. ValidatorDB (freely available at http://ncbr.muni.

MotiveValidator: interactive web-based validation of ligand and residue structure in biomolecular complexes.

Structure validation has become a major issue in the structural biology community, and an essential step is checking the ligand structure. This paper introduces MotiveValidator, a web-based application for the validation of ligands and residues in PDB or PDBx/mmCIF format files provided by the user. Specifically, MotiveValidator is able to evaluate in a straightforward manner whether the ligand or residue being studied has a correct annotation (3-letter code), i.
