DNA mismatch repair (MMR) is an efficient system for the detection and repair of mismatched and unpaired bases in DNA. Deficiencies in MMR are commonly found in both hereditary and sporadic colorectal cancers, as well as in cancers of other tissues. Because fluorinated thymidine analogues (which through their actions might generate lesions recognizable by MMR) are widely used in the treatment o...

DNA is constantly under attack by a number of both exogenous and endogenous agents that challenge its integrity. Among the mechanisms that have evolved to counteract this deleterious action, mismatch repair (MMR) has specialized in removing DNA biosynthetic errors that occur when replicating the genome. Malfunction or inactivation of this system results in an increase in spontaneous mutability ...

In this paper, we present an analysis of mobile multihop relay (MMR) technology using cooperative multiple-input-multiple-output (MIMO) transmission. New wireless broadband protocols, such as WiMAX, and 3G-LTE apply MIMO technology, and mobile communication protocols under standardization are investigating MMR as a future technology to use. These two technologies are expected to be among the mo...

Although human cells exposed to DNA-methylating agents undergo mismatch repair (MMR)-dependent G(2) arrest, the basis for the linkage between MMR and the G(2) checkpoint is unclear. We noted that mitogen-activated protein kinase p38alpha was activated in MMR-proficient human glioma cells exposed to the chemotherapeutic methylating agent temozolomide (TMZ) but not in paired cells made MMR defici...

BACKGROUND In the United States, children receive 2 doses of measles-mumps-rubella vaccine (MMR) and varicella vaccine (V), the first between ages 1 to 2 years and the second between ages 4 to 6 years. Among 1- to 2-year-olds, the risk of febrile seizures 7 to 10 days after MMRV is double that after separate MMR + V. Whether MMRV or MMR + V affects risk for febrile seizure risk among 4- to 6-ye...

BACKGROUND Public debate over the safety of the trivalent measles, mumps and rubella (MMR) vaccine, and the resultant drop in vaccination rates in several countries, persists despite its almost universal use and accepted effectiveness. OBJECTIVES We carried out a systematic review to assess the evidence of effectiveness and unintended effects associated with MMR. SEARCH STRATEGY We searched...
