PURPOSE To evaluate the benefit of titrating the concentration and exposure time of mitomycin C (MMC) as an adjunct to trabeculectomy. METHODS This report consists of a retrospective study and a review of the literature. In the study, consecutive glaucoma patients were evaluated who underwent trabeculectomy with adjunctive MMC that was titrated for concentration and exposure time, based on pa...

PURPOSE To determine whether application of the anti-proliferation agent, mitomycin C (MMC), to the osteotomy site during dacryocystorhinostomy (DCR) surgery increases surgical success rates. METHOD We conducted a comprehensive meta-analysis of randomised controlled clinical studies relating to the adjunctive use of MMC in primary and revision, as well as external (EX-DCR) and endonasal DCR (...

OBJECTIVE Mitomycin C (MMc) is an antibiotic that exerts a potent antiproliferative effect in tumor cells. Because the proliferation of vascular smooth muscle cells (VSMCs) plays a prominent role in the development of restenosis after percutaneous coronary interventions, the present study examined the effect of MMc on VSMC proliferation and on neointima formation after arterial balloon injury. ...

Mitomycin c (MMC), a quinone-containing anticancer drug, is known to redox cycle and generate reactive oxygen species. A key enzyme mediating MMC redox cycling is cytochrome P450 reductase, a microsomal NADPH-dependent flavoenzyme. In the present studies, Chinese hamster ovary (CHO) cells overexpressing this enzyme (CHO-OR cells) and corresponding control cells (CHO-WT cells) were used to inves...

The S1 state dynamics of methoxy methylcinnamate (MMC) has been investigated under supersonic jet-cooled conditions. The vibrationally resolved S1-S0 absorption spectrum was recorded by laser induced fluorescence and mass-resolved resonant two-photon ionization spectroscopy and separated into conformers by UV-UV hole-burning (UV-UV HB) spectroscopy. The S1 lifetime measurements revealed differe...

background: lymphocytes of fanconi anemia (fa) show an increased sensitivity to the alkylating agents such as mitomycin c (mmc), but their responses to gamma-irradiation is controversial. the extent of dna damage in leukocytes of fa patients following irradiation and mmc treatment was studied at cellular and single chromosome level. methods: dna damage induced by gamma-rays and mmc was measured...

purpose : although applying mitomycin c (mmc) during photorefractive keratectomy (prk) has shown to reduce postoperative corneal haze but there is considerable evidence of mmc toxicity in the literature and concerns exist regarding side effects and long-term complications. we conducted this study to compare the efficacy of mmc 0.02% and 0.01% in prevention of haze after prk. methods : 210 eyes ...

CONTEXT Since 2000, the Centers for Medicare & Medicaid Services (CMS) has been collecting information on beneficiaries' experiences with health care for Medicare managed care (MMC) and traditional fee-for-service (FFS) Medicare. OBJECTIVES To compare beneficiary experiences with managed care and FFS arrangements throughout the country and to assess the stability of those differences over tim...

Mitomycin C (MMC) is a DNA cross-linking agent that has been used in cancer chemotherapy for over 20 years, yet little is known either qualitatively or quantitatively about MMC-induced DNA adduct forma tion and repair in vivo. As an initial means of investigating this, we used a recently developed 32P-postlabeling assay to examine the formation and loss of MMC-DNA adducts in the tissues of a si...

BMY-25282, 7-N-(dimethylamino methylene)mitomycin C, is one of a novel series of amidino mitomycin derivatives. Some of these were discovered as intermediates in a synthetic program being conducted to find improved procedures for modifying the structure of mitomycin C (MMC). Markedly superior in vivo antitumor effects have been observed with BMY-25282 compared to MMC in initial tests against i....
