Cerebral palsy is the most frequent cause of severe physical disability in childhood. Dyskinetic cerebral palsy (DCP) is the second most common type of cerebral palsy after spastic forms. DCP is typically caused by non-progressive lesions to the basal ganglia or thalamus, or both, and is characterised by abnormal postures or movements associated with impaired tone regulation or movement coordination. In DCP, two major movement disorders, dystonia and choreoathetosis, are present together most of the time. Dystonia is often more pronounced and severe than choreoathetosis, with a major effect on daily activity, quality of life, and societal participation...

Two extracellular peroxidases from Bjerkandera adusta strain CX-9, namely a lignin peroxidase (called LiP BA45) and manganese peroxidase (called MnP BA30), were purified simultaneously by applying successively, ammonium sulfate precipitation-dialysis, Mono-S Sepharose anion-exchange and Sephacryl S-200 gel filtration and biochemically characterized. The sequence of their NH2-terminal amino acid residues showed high homology with those of fungi peroxidases. MALDI-TOF/MS analysis revealed that the purified enzymes MnP BA30 and LiP BA45 were a monomers with a molecular masses 30125...

The 2 main degradative pathways that contribute to proteostasis are the ubiquitin-proteasome system and autophagy but how they are molecularly coordinated is not well understood. Here, we demonstrate an essential role for an effector caspase in the activation of compensatory autophagy when proteasomal activity is compromised. Functional loss of Hsp83, the Drosophila ortholog of human HSP90 (heat shock protein 90), resulted in reduced proteasomal activity and elevated levels of the effector caspase Dcp-1. Surprisingly, genetic analyses showed that the caspase was not required for cell death in this context, but instead was essential for the ensuing compensatory autophagy, female fertility, and organism viability...

The experiment was conducted to test the hypothesis that the replacement of cereal with low-starch feed ingredients in lambs' finishing diets supplemented with oils could prevent the accumulation of -10-18:1 in meat. Forty lambs were fed 1 of 4 diets supplemented with soybean oil (5.9%) and fish oil (1%) for 6 wk before slaughter. The control (CON) diet contained 43% barley, and in the other diets, barley was completely replaced by dehydrated citrus pulp (DCP), dehydrated sugar beet pulp (DBP), or soybean hulls (SH)...

A clean way to overcome environmental pollution is biodegradation. In this perspective, at the intersection of biodegradation and metagenomics, the degradome is defined as the totality of genes related to the biodegradation of a certain compound. It includes the genetic elements from both culturable and uncultured microorganisms. The possibility of assessing the biodegradation potential of an environmental samples, using a degradome-based polymerase chain reaction, was explored. 2,4-Dichlorophenol (2,4-DCP) was chosen as a model and the use of tfdB gene as a biodegradation marker was confirmed by bioinformatics study of TfdB protein...

AIM: The prognostic significance of the half-lives (HLs) of alpha-fetoprotein (AFP) and des-γ-carboxy prothrombin (DCP) in patients undergoing hepatectomy for hepatocellular carcinoma (HCC) is unclear. We evaluated the HLs of AFP and DCP in a cohort of such patients. METHODS: This study included data on 202 patients with HCC who underwent curative hepatectomy and had preoperative AFP concentrations ≥ 100 ng/mL or DCP ≥ 200 mAU/mL. We calculated the HLs of AFP and DCP from their values just before and one month after hepatectomy...

Photovoltammetric behaviors of irreversible, quasi-reversible and reversible electrochemical systems represented by 2,4-dichlophenol (DCP), hydroquinone (HQ) and K3[Fe(CN)6], respectively, were investigated on a CdS-graphene hybrid film electrode. The cyclic voltammetric (CV) curves of HQ and K3[Fe(CN)6] showing a pair of redox peaks became sigmoidal in shape under visible light irradiation. In contrast, the CV curve shape of DCP showing an oxidation peak was not changed under photoirradiation, although the oxidation peak current was enhanced by the photoelectrocatalysis...

In this study, we investigated the effect of supplementing a non-dispersive dicalcium phosphate-rich calcium phosphate bone cement (DCP-rich CPC) with type I collagen on in vitro cellular activities and its performance as a bone graft material. Varying amounts of type I collagen were added during the preparation of the DCP-rich CPC. In vitro cell adhesion, morphology, viability, and alkaline phosphatase (ALP) activity were evaluated using progenitor bone cells. Bone graft performance was evaluated via a rat posterolateral lumbar fusion model and osteointegration of the implant...

Cobalt phosphate (CoPi) is a promising cocatalyst for the (photo)electrochemical oxidation of water over semiconductor electrodes in phosphate solution, but the effect of CoPi on organic oxidation reactions has been little studied. Herein, we report a compound-sensitive effect of CoPi on the TiO2-photocatalyzed oxidation of phenol, 4-chlorophenol (CP), and 2,4-dichlorophenol (DCP) in a phosphate-containing suspension at pH 7.0. A photochemical method was used to deposit Pt onto TiO2 and then CoPi onto both Pt/TiO2 and TiO2...

Cross-linking improves the wear resistance of ultrahigh molecular weight polyethylene (UHMWPE) used in hip and knee implants. Free radicals, generated by ionizing radiation or chemically, react to form cross-links. Limiting cross-linking to the articulating surface of the implant is desirable to enable high wear resistance on the surface and higher strength and toughness in the bulk. We investigated the diffusion of emulsified dicumyl peroxide (DCP) into vitamin E-blended UHMWPE (0.1 and 0.3 wt. % vitamin-E) with subsequent thermal decomposition in situ to obtain surface cross-linking with the objective of achieving surface wear rate equivalent or lower than that of current clinically available materials...

We retrospectively reviewed outcomes of 79 patients with periprosthetic hip fractures around cemented tapered polished stem (CTPS) implants treated with osteosynthesis between January 1997 and July 2011. All patients underwent open reduction and fixation using a broad dynamic compression plate (DCP). Seventy two (91%) of fractures united. There were seven (9%) non-unions with failure of metal work, three (4%) as a result of infection and four (5%) due to mechanical failure. Significant subsidence (>5mm) of the implant was seen in seven (9%) of cases...

Nerve agents are highly toxic organophosphorus compounds, and their possible use in terrorist attacks has led to increasing interest in the development of reliable and accurate methods to detect these lethal chemicals. In this paper, we have prepared six 6-aminoquinolines with various N-substituents as chemosensors for a nerve-agent mimic diethylchlorophosphate (DCP). The chemosensors with the nucleophilic pyridine-N atom as the active site detect DCP via a catalytic hydrolysis approach to form the protonated sensor...

Algal growth inhibition tests are generally used to determine the toxic effects of chemical substances on algae growth. In this report, we describe a rapid and simple test procedure using delayed fluorescence (DF) to determine chemical toxicities more rapidly than the conventional 72h or 96h growth inhibition tests. We assess the suitability of DF to serve as an alternative endpoint for biomass production and determine the variability by an interlaboratory ring study using a typical reference toxicant 3,5-dichlorophenol (DCP)...
