Epidural scar formation after laminectomy impede surgical outcomes of decompression. Mitomycin C (MMC) has been demonstrated to have significant inhibitory effects on epidural scar. This study was undertaken to develop an effective MMC controlled‑release membrane and to investigate its effects on epidural scar in rat models of laminectomy. A total of 72 rats that underwent laminectomy were divi...

  Background: Children with myelomeningocele (MMC) develop a wide variety of hip deformities such as muscle imbalance, contracture, subluxation, and dislocation. Various methods and indications have been introduced for treatment of muscle imbalances and other hip problems in patients with MMC but there is no study or meta-analysis to compare the results and complications. This review aims to fi...

Absorption and lymphatic transfer of a polymeric prodrug of mitomycin C (MMC), mitomycin C-dextran conjugate (MMC-D), following i.m. injection were studied in rats in order to assess the feasibility of a macromolecular prodrug as a lymphotropic delivery system. Three types of MMC-D, conjugates with dextran with molecular weights of 10,000, 70,000 and 500,000, were synthesized, and the dispositi...

Environmental and electrical factors such as wind speed, air temperature switching frequency have significant influences on the operational reliability of hybrid modular multilevel converter (MMC), which is commonly used for power transmission. However, existing model MMC based statistics cannot accurately reflect impact these factors. In this paper, a new presented. The index coupled with its ...

The interaction of hyperthermia and mitomycin C (MMC) was studied in wild-type Chinese hamster ovary cells and in Chinese hamster ovary cells selected for resistance to MMC. Hyperthermic potentiation of MMC activity was maximal if heating was done simultaneously, or up to 3 h following MMC exposure. Heat enhanced the effect of MMC in both drug-sensitive and -resistant cells. Dose enhancement ra...

Conjugates of mitomycin C (MMC) with estradiol bezoate and estradiol via glutaric acid (EB-glu-MMC and E-glu-MMC, respectively) were examined for their antitumor activities against P388 leukemia and sarcoma 180. EB-glu-MMC and E-glu-MMC were suspended in 10% (v/v) propylene glycol in saline and administered intraperitoneally to mice bearing P388 leukemia intraperitoneally or to mice bearing sar...

The wideband oscillation of the hybrid modular multilevel converter (MMC)induced by excessive power infeed under weak ac system integration is analyzed in this article. A closed-loop state-space-based time-domain small-signal model firstly established to investigate instability problem. Different from findings two-level voltage-source-converters (VSCs) or half-bridge MMCs, root locus analysis a...

Cellular interaction and in vitro antitumor activity of a polymeric prodrug of mitomycin C (MMC), mitomycin C-dextran conjugate (MMC-D), were studied in relation to its physicochemical characteristics. MMC-D with cationic and anionic charges were examined. The cationic MMC-D was synthesized using a spacer, epsilon-aminocaproic acid and dextrans with molecular weights of 10,000, 70,000, or 500,0...

Fanconi anemia (FA) is a genetic disorder that leads to aplastic anemia and birth defects and predisposes to cancer. FA cells exhibit characteristic hypersensitivity to DNA cross-linking agents such as mitomycin C (MMC), and FANCG is one of six known FA gene products. By immunocytochemical analysis of transfected cells, we discovered that although FANCG localized to both the nucleus and cytopla...

Increasing the modulation index by utilizing negative voltage states of full-bridge submodules (FBSMs) can greatly reduce capacitor usage modular multilevel converters (MMCs), thereby optimizing cost and volume. The hybrid MMC is composed half-bridge (HBSMs) FBSMs, voltages two types (SMs) have different shapes as long exist. This condition complicates analysis design energy storage requirement...
