PURPOSE: Our purpose was to evaluate the clinical safety and efficacy of CO2 laser-assisted sclerectomy surgery (CLASS) with Mitomycin C (MMC) in open angle glaucoma (OAG). METHODS: This was a prospective, uncontrolled, interventional case series. All subjects underwent CLASS procedure by a single surgeon. After the dissection of a partial thickness scleral flap, topical MMC 0.2 mg/ml was applied to the sclera and the conjunctiva for 3 min. The CO2 laser with a beam-manipulating system was used to ablate the scleral tissue and expose the Schlemm's canal area...

Chemotherapeutic insensitivity is one of key obstacles to effectively treating muscle invasive bladder cancer. 5-Aza-2'-deoxycytidine (5-Aza-CdR) has been identified as a tumor suppressive agent in various types of cancer. The aim of the present study was to identify the effects of 5-Aza-CdR on the mitomycin-C (MMC) chemosensitivity of T24 bladder cancer cells and investigate the underlying mechanisms. T24 cells were treated with a combination of MMC and 5-Aza-CdR at various concentrations. The rates of proliferation and apoptosis were assessed by an MTT assay and flow cytometry, respectively...

Neisseria meningitidis (Nm) is a Gram-negative nasopharyngeal commensal that can cause septicaemia and meningitis. The neisserial DNA damage-inducible protein DinG is a helicase related to the mammalian helicases XPD and FANCJ. These helicases belong to superfamily 2, are ATP dependent and exert 5' → 3' directionality. To better understand the role of DinG in neisserial genome maintenance, the Nm DinG (DinGNm) enzymatic activities were assessed in vitro and phenotypical characterization of a dinG null mutant (NmΔdinG) was performed...

Introduced in 2008 and subsequently popularized in South Korea, cosmetic eye whitening has been offered as a treatment of chronic conjunctival hyperemia. Patients undergo conjunctivectomy with topical mitomycin C (MMC) 0.02% application to achieve a whitened appearance from bleaching of avascular sclera. Much speculation has arisen from this procedure given the limited available evidence on its efficacy and safety. A literature search was performed to review common complications of cosmetic eye whitening, including chronic conjunctival epithelial defects, scleral thinning, avascular zones in the sclera, dry eye syndrome, and diplopia requiring strabismus surgery...

Children with cancer treated with cytotoxic drugs are frequently at risk of developing renal dysfunction. The cytotoxic drugs that are widely used for cancer treatment in children are cisplatin (CPL), ifosfamide (IFO), carboplatin, and methotrexate (MTX). Mechanisms of anticancer drug-induced renal disorders are different and include acute kidney injury (AKI), tubulointerstitial disease, vascular damage, hemolytic uremic syndrome (HUS), and intrarenal obstruction. CPL nephrotoxicity is dose-related and is often demonstrated with hypomagnesemia, hypokalemia, and impaired renal function with rising serum creatinine and blood urea nitrogen levels...

Reactive oxygen species (ROS) are generated in the cell through multiple mechanisms. Intracellular ROS are rapidly detoxified by various enzymatic and non-enzymatic mechanisms; however, disruption of the oxidant-antioxidant balance causes oxidative stress and elicits cell damage. The oxidative stress induced by chemotherapy is known to cause side effects in patients with cancer. However, few studies have examined whether anticancer drugs induce oxidative stress in cancer cells. Furthermore, the precise mechanism by which anticancer drugs induce the generation of ROS remains unclear...

Earlier work in our laboratory demonstrated that naturally occurring reveromycin A (Rev A) causes apoptosis in osteoclasts without accompanying necrosis. Rev A death effects in both normal and diseased joint cells were investigated in this study. 10 □M Rev A did not cause apoptosis nor necrosis in monolayer chondrocytes, even at pH 6.8, a pH mimicking that of an inflamed joint. In contrast, at the acidic pH Rev A did induce significant apoptosis (four-fold increase at 48 hours of treatment, p<0.005) in normal synoviocytes without accompanying necrosis...

Cyclophosphamide(CY)was intraperitoneally administered once a week to C57BL/10mice that had received Rous sarcoma virus(RSV)-induced S1018B10 syngeneic tumor transplantation and in whom tumor diameter exceeded 4.5 mm. Survival was prolonged in a group of mice that also received a mixture of LEM and MAK orally. When splenic cells were cultured under mitomycin C-treated S1018B10 stimulation and the S1018B10-directed cell killing ability was examined, the effector cells were found to be F4/80 - DC/Mф cells. Flow cytometric analysis showed that the proportion of F4/80- DC/Mф cells in the splenic cell culture of the CY+LEM+MAK treatment group was higher than that in the untreated group...

BACKGROUND: Transarterial chemoembolization (TACE) is recommended as the standard care for unresectable hepatocellular carcinoma (HCC) at Barcelona Clinic Liver Cancer (BCLC) stage A-B. However, the efficacy of TACE on large (≥ 10 cm) stage A-B HCC is far from satisfactory, and it is proposed that hepatic artery infusion chemotherapy (HAIC) might be a better first-line treatment of this disease. Hence, we compared the safety and efficacy of HAIC with the modified FOLFOX (mFOLFOX) regimen and those of TACE in patients with massive unresectable HCC...
