OBJECTIVE To evaluate the effect of dimethyl fumarate (DMF; Tecfidera, Biogen, Weston, MA) on CD4(+) and CD8(+) T cell subsets in patients with multiple sclerosis (MS). METHODS Peripheral lymphocyte subsets, including CD4(+) and CD8(+) memory cells and T helper (TH) cells TH1, TH2, TH17, and peripheral regulatory T cell (pTreg) subpopulations were analyzed before and 6 months after onset of D...

The objective of this study was to examine the ability of dietary polyphenols to inhibit cytochrome P450 (CYP) 1A1 expression and activity and benzo[a]pyrene (BaP) DNA binding, with the main emphasis on prevention of chemical-induced hepatic carcinogenesis. For this purpose we used Hep G2 cells, a good model of the normal human hepatocyte for CYP1A1 cell signaling. First, when these cells were ...

N,N-dimethylformamide (DMF) is a major solvent predominantly used in the chemical industry. The main toxic effects following exposure to DMF are gastric irritation, skin eruption and hepatotoxicity. However, hepatic failure induced by DMF is rare. In this report, we present a case of acute hepatic failure following exposure to a toxic dose of DMF via respiratory tract inhalation and skin absorp...

The title complex salt, (C8H20N)[ZnCl3(C3H7NO)], contains one [Et4N](+) cation (Et is ethyl) and one [ZnCl3(DMF)](-) anion (DMF is di-methyl-formamide). In the anion, the zinc atom is tetra-hedrally coordinated by a DMF ligand via the O atom and by three terminal Cl atoms. The average Zn-Cl bond length and Cl-Zn-Cl angle are 2.243 (11) Å and 114 (3)°, respectively.

Pyridyl functionalized host molecules are oxidized to their N-oxide analogues and form a series of coordination polymers and discrete complexes with transition metal cations. Complex {[Ag(3)(NMP)(6)(L1)(2)]·3(ClO(4))}(∞) where L1 = tris(isonicotinoyl-N-oxide)cyclotriguaiacylene, NMP = N-methylpyrrolidone, is a three-dimensional (3-D) 3,6-connected coordination polymer of pyrite-like (pyr) topol...

Microfluidics is an attractive platform for chemical synthesis because it offers fast reaction times, reduced reagent usage, and the ability to integrate multiple functions on a single device. Digital Microfluidics (DMF) is particularly well-suited for microscale chemical synthesis, as it permits discretized sample handling, allowing for total process control. However, a limitation of DMF-based...

Dimethyl fumarate (DMF) is approved for disease-modifying treatment of patients with relapsing-remitting multiple sclerosis. Animal experiments suggested that part of its therapeutic effect is due to a reduction of T-cell infiltration of the central nervous system (CNS) by uncertain mechanisms. Here we evaluated whether DMF and its primary metabolite monomethyl fumarate (MMF) modulate pro-infla...

UNLABELLED A promising approach to neurotherapeutics involves activating the nuclear-factor-E2-related factor 2 (Nrf2)/antioxidant response element signaling, which regulates expression of antioxidant, anti-inflammatory, and cytoprotective genes. Tecfidera, a putative Nrf2 activator, is an oral formulation of dimethylfumarate (DMF) used to treat multiple sclerosis. We compared the effects of DM...

INTRODUCTION Dimethyl fumarate (DMF) has been recently approved as a disease-modifying therapy for the treatment of multiple sclerosis (MS). Post-marketing studies are important to confirm what was established in clinical trials. OBJECTIVE To evaluate effectiveness and safety of DMF and to measure the occurrence of lymphopenia in a cohort of MS patients in a clinical setting. METHODS Using ...

OBJECTIVES The aims of this cross-sectional study were to evaluate the level of fear of dental procedures among schoolchildren and assess the relationship between caries experience and fear of dental procedures. SUBJECTS AND METHODS 275 children aged 7-11 years were recruited for the study. Before conducting a dental examination, each subject was asked to independently complete a Children's F...
