We previously reported a novel association between CDKN2A nonpromoter methylation and transcription (ARF/INK4a) in human papillomavirus associated oropharyngeal tumors. In this study we assessed whether nonpromoter CDKN2A methylation in laryngeal squamous cell carcinomas (LXSCC) conferred a similar association with transcription that predicted patient outcome. We compared DNA methylation and ARF/INK4a RNA expression levels for the CDKN2A locus using the Illumina HumanMethylation27 beadchip and RT-PCR in 43 LXSCC tumor samples collected from a prospective study of head and neck cancer patients treated at Montefiore Medical Center (MMC)...

BACKGROUND/AIMS: To compare the efficacy and safety of subtenon injection of mitomycin C (MMC) with that of conventional application of MMC-soaked sponges in trabeculectomy. METHODS: In this multicentre randomised clinical trial, 80 consecutive open-angle glaucoma cases were randomised into two groups; group 1 received a subtenon injection of 0.1 mL of 0.01% MMC, while group 2 received 0.02% MMC-soaked sponges. Primary outcome measure was intraocular pressure (IOP), and secondary outcome measures were endothelial cell count (ECC) changes and bleb morphology according to the Indiana Bleb Appearance Grading Scale...

Maternal microchimerism (MMc) has been associated with development of allospecific transplant tolerance, antitumor immunity, and cross-generational reproductive fitness, but its mode of action is unknown. We found in a murine model that MMc caused exposure to the noninherited maternal antigens in all offspring, but in some, MMc magnitude was enough to cause membrane alloantigen acquisition (mAAQ; "cross-dressing") of host dendritic cells (DCs). Extracellular vesicle (EV)-enriched serum fractions from mAAQ(+), but not from non-mAAQ, mice reproduced the DC cross-dressing phenomenon in vitro...

Alpha-momorcharin (α-MMC), a type I ribosome inactivating protein, has attracted a great deal attention because of its antitumor activity. However, the cytotoxicity of α-MMC is limited due to insufficient cellular internalization in cancer cells. To enhance the cytotoxicity of α-MMC, a heparin-binding domain derived from HB-EGF (named HBP) was used as a cell-penetrating peptide and fused to the C-terminus of α-MMC. This novel α-MMC-HBP fusion protein was expressed and purified with a Ni(2+) -resin. The N-glycosidase activity and DNase activity assay indicated that the introduction of HBP did not interfere with the intrinsic bioactivities of α-MMC...

PURPOSE: To compare the efficacy and safety of topical interferon alpha 2b (IFNα2b) and mitomycin C (MMC) for ocular surface squamous neoplasia. METHODS: In this retrospective study, medical records of 51 eyes of 50 patients with a diagnosis of primary ocular surface squamous neoplasia were included. All cases were treated with either topical IFNα2b (1 million IU/mL) or MMC (0.4 mg/mL) 4 times a day. The primary outcome measure was frequency of clinical resolution of tumors along with failure and recurrence rates after treatment...

BACKGROUND: Interactions between genes and environment are critical factors for causing cancer in humans. The genotoxicity of environmental chemicals can be enhanced via the modulation of susceptible genes in host human cells. DNA polymerase kappa (Pol κ) is a specialized DNA polymerase that plays an important role in DNA damage tolerance through translesion DNA synthesis. To better understand the protective roles of Pol κ, we previously engineered two human cell lines either deficient in expression of Pol κ (KO) or expressing catalytically dead Pol κ (CD) in Nalm-6-MSH+ cells and examined cytotoxic sensitivity against various genotoxins...

A problem of community-acquired Staphylococcus aureus skin infections emerged in the French armed forces in 2004, in a malaria-endemic areas. The high incidence rate led us to evaluate military staff practices. This was a cross-sectional survey of doctors and nurses deployed as officers in French Guyana since 2006. The definition of skin and soft-tissue infection came from the criteria for epidemiological surveillance of the armed forces. We studied the management of antibiotic therapy and its related difficulties...

In this study, the effect of radiofrequency (RF) exposure to 1950 MHz, Universal Mobile Telecommunication System signal, was investigated in Chinese hamster lung fibroblast cell line (V79). Genotoxic and cytotoxic effects of 20-h exposure at specific absorption rate (SAR) values from 0.15 W/kg to 1.25 W/kg were measured by means of cytokinesis-block micronucleus (MN) assay. Exposure was carried out blinded under strictly controlled conditions of dosimetry and temperature. The effect of RF exposure alone at four SAR values was tested, that is, 0...

BACKGROUND: Amongst the different at-risk periods for mother-to-child HIV transmission that is, during pregnancy, labor and delivery and breastfeeding, much care and attention needs to be given, not only to the child as concerns its feeding options, but also to the mother. The aim of this study was to determine the nutritional habits and health outcomes of HIV-positive breastfeeding mothers in the Dschang Health District, in the context of prevention of mother-to-child transmission (PMTCT) activities...

Congenital diaphragmatic hernia (CDH) is a rare birth defect with a prevalence of < 0.5 per 1,000 live births. Majority of these defects are left-sided as most studies suggest that frequency of right-sided CDH was 10% of the total. The association of CDH with myelomeningocele (MMC) is extremely rare; as in Sweed's study of 116 consecutive cases of CDH, the incidence of associated MMC with CDH was stated as 4.3%. There has been one previous case report of leftsided CDH, MMC and hydrocephalus prenatally diagnosed; but to the best of authors' knowledge, this is the first reported case of the above constellation with a right-sided CDH diagnosed prenatally...

BACKGROUND: Antifibrotic agents are commonly utilized to enhance the success rates of trabeculectomy. Novel approaches to further improve success rates and reduce the risks of complications are needed. The purpose of this study was to compare intraocular pressure (IOP)-lowering efficacy and safety of trabeculectomy or combined phacoemulsification and trabeculectomy with mitomycin-C (MMC) vs. Collagen Matrix (CM). METHODS: A prospective, multicenter, randomized controlled trial was performed...

FA is a rare recessive genetic disorder with autosomal or X-linked mode of inheritance and is associated with 19 different FA complementation groups. We have studied three patients clinically diagnosed as FA. All three patients showed a high frequency chromosomal breakage in MMC induced blood cultures and FANCD2 non-monoubiquitination by western blotting. The molecular analysis using direct sequencing revealed two novel mutations in FANCG; 2 novel mutations c.1143+5G>C and c.883dupG, and a reported mutation c...

Twenty new rare-earth metal rich intermetallic aluminium compounds, RE10TAl3 (RE = Y, Ho, Tm, Lu; T = Fe, Co, Ni, Ru, Rh, Pd, Os, Ir, Pt), were synthesized by arc melting the elements. The compounds crystallize, in analogy to e.g. the respective Cd representatives, with a ternary ordered structure as anti-type to the hexagonal Co2Al5 type, with the space group P63/mmc. The three crystallographically independent rare-earth metal sites occupy the aluminium positions of the aristotype, while the transition metal and aluminium atoms are ordered on the two cobalt sites...

Intravesical gemcitabine has recently been introduced for the treatment of superficial bladder cancer and has a favourable efficacy and toxicity profile in comparison to mitomycin c (MMC), the most commonly used chemotherapeutic agent. The aim of this study was to assess the cytotoxic potency of gemcitabine in comparison to MMC in urothelial cell lines derived from non-malignant (UROtsa) and malignant (RT4 and T24) tissues to assess selectivity. Cells were treated with gemcitabine or mitomycin C at concentrations up to the clinical doses for 1 or 2h respectively (clinical duration)...

The multifactorial pathogenesis of HIV-associated neurocognitive disorders may explain the inconsistent association between neurocognitive impairment and cerebrospinal fluid (CSF) HIV RNA. Clinical and viro-immunological (CSF and plasma HIV RNA, CSF/plasma HIV RNA ratio, circulating T-cell phenotypes) parameters were investigated in 155 HIV-infected, antiretroviral-naïve, asymptomatic study participants undergoing a neuropsychological evaluation. HIV associated neurocognitive disorders (HAND) was independently associated with AIDS events and a CSF/plasma ratio of at least one, after adjustment for CD4 nadir of less than 200 cells/mmc, suggesting a role for active central nervous system (CNS) viral replication in the pathogenesis of neurocognitive impairment...
