Anterior leaflet prolapse. To repair or not to repair?
Journal of Cardiac Surgery, 2022A larger use of mitral valve repair is recommended in case of mitral regurgitation. Anterior leaflet repair is generally more difficult than posterior. Presence of atrial fibrillation or dysfunction of left ventricle appears to be independent preoperative factors of failure in case of involvement of the anterior leaflet.

On Repair Age Residual Repair Life in the Minimal Repair Process
Probability in the Engineering and Informational Sciences, 1989Some properties of repair age (the elapsed time since the last repair) and the residual repair life (the time until the next repair) are studied for the minimal repair process under various assumptions on the aging characteristics of the equipment under maintenance. Bounds on expected repair age and expected residual repair life are obtained.

Transplantation of fetal neural cells represents an attractive replacement strategy for the treatment of certain neurodegenerative diseases. This is the case with Parkinson's disease, which results from a selective loss of dopaminergic neurons of the substantia nigra. Experimentation with animal models has demonstrated the feasibility of this approach.

DNA repair and cell repair: Are they related?
International Journal of Radiation Oncology*Biology*Physics, 1979Abstract Evidence of damage-repair processes is reviewed in connection with 3 types of cytotoxic cell treatments: X-radiation; far-ultraviolet (UV) (254 nm) light; and fluorescent light (FL) exposure of cells that had been grown in the presence of 5-bromodeoxyuridine (BUdR).

DNA replication, repair, and repair tests
Journal of Toxicology and Environmental Health, 1980The rate of inhibition and recovery of DNA synthesis can be used in a rapid assay system to detect genotoxic potentials of chemicals. Also, the observation that an agent stimulates DNA repair in a test system indicates its ability to cause damage in DNA. Different experimental approaches to the study of repair synthesis are discussed.

Repairability?the path to industrialization of repairs
Metallurgist, 1981At the current stage of development of the ferrous metallurgy sector, one of the most important reserves for increasing productivity is improving the repair and maintenance system. The yearly increase in the amount of equipment in use and the increasing complexity of this equipment make it necessary to augment present repair services.

Construction of the congenitally absent ear is a particular challenge. It represents the true essence of plastic surgery in that it not only requires sound surgical principles but artistic skill. Although a solid familiarity with the stages is important, the surgeon's own experience will direct gradual modification.

Angewandte Chemie International Edition, 2015
DNA is constantly damaged by various endogenous and exogenous events. Repair systems constantly scan the genome for DNA lesions and replace damaged and mismatched bases, which finally enables the complex DNA double strand to store genetic information. This year's Nobel Prize in Chemistry was awarded to pioneers in this field, T. Lindahl, P.
