A series of mesoporous catalysts (MCM-41) promoted by copper oxide nanoparticles were prepared by the co-precipitation method and tested for the decomposition of carbon tetrafluoride (CF4). The addition of copper oxide nanoparticles to MCM-41 led to an improvement in the catalytic activity for CF4 decomposition. The catalyst was the most active around 5 wt% copper oxide added to MCM-41. Methods...

This work examines whether microglia-conditioned medium (MCM) is beneficial in stressed spinal cord cells or tissues. MCM was separated into two fractions by 50 kDa molecular cut-off centrifugation. MCM not only promoted survival of neuronal and oligodendroglial cells but effectively reduced LPS stimulation in spinal cord cultures. We further utilized the NYU weight-drop device to induce contus...

The impact of zeolite hierarchization is often highlighted in terms increased mesopore volume or specific surface area and preservation micropore volume. Yet, although these targets may be achieved, the accessibility to certain micropores might negatively affected during hierarchization. A set hierarchical MCM-22 based materials prepared on desilication treatments MCM-22, layered precursor MCM-...

We present neutron scattering measurements of the excitations of liquid He confined in MCM-41 at wave vectors 0.35 Å<q<2.15 Å . MCM-41 is a uniform porous material consisting of cylindrical pores, here of 32 Å diameter. The location and phase of He in the pores was well characterized by pressure isotherms and by exploratory neutron scattering measurements. The first 60% of He entering the MCM-4...

The goal of this research was to investigate the potential of newly synthesized gold complex trichloro(2,4,6-trimethylpyridine)Au(III) as an anticancer agent. The gold(III) complex was synthesized and grafted on nanoporous silica, MCM-41, to produce AuCl(3)@PF-MCM- 41 (AuCl(3) grafted on pyridine-functionalized MCM-41). The toxicity of trichloro(2,4,6- trimethylpyridine)Au(III) and AuCl(3)@PF-M...

The essential role of MCM 2-7 proteins in the initiation of DNA replication in all eukaryotes is well known. Their role in replication elongation is supported by numerous studies, but there is still a knowledge gap in this respect. Even though biochemical studies have established an association of MCM proteins with replication forks, previous immunofluorescence studies in mammalian cells have s...

Sugarcane cultivation is suitable for the exploitation of organic waste products. However, minimum complementary mineral input necessary optimal fertilisation. Control fertilisation treatments with mulch (MCM) or without (MC) were compared two treatments, a pig slurry (PSM) and (PS), sugarcane vinasse (SVM) (SV) on Nitisol in French Reunion Island. The yields obtained different differed each ye...

OBJECTIVE To assess the relative risk of major congenital malformation (MCM) from in utero exposure to antiepileptic drug (AEDs). METHODS Prospective data collected by the UK Epilepsy and Pregnancy Register were analysed. The presence of MCMs recorded within the first three months of life was the main outcome measure. RESULTS Full outcome data were collected on 3607 cases. The overall MCM r...
