Purpose: This article introduces and provides initial data supporting "The Early Development of Emotional Competence (EDEC): A tool for children with complex communication needs (CCNs)." The EDEC was developed to raise awareness about the relation of language and emotional competence and to maximize the likelihood that intervention includes language to discuss emotions in ways that are consistent with the values and goals of the family.

Method: First, the theoretical and clinical foundations of the EDEC development were discussed.

Purpose: Children with Down syndrome often have more restricted emotion expression and recognition skills than their peers who are developing typically, and potentially fewer opportunities to learn these skills. This study investigated the effect of the Strategies for Talking about Emotions as PartnerS (STEPS) programme on parents' provision of opportunities for emotion communication using visual communication supports.

Method: The study used a single-subject multiple-baseline across participants design with three parent-child dyads.

Sortilin-related receptor 1 (SORL1) is a neuronal sorting protein that reduces amyloid precursor protein (APP) trafficking to secretases that generate amyloid beta (Aβ). Although 6-shogaol, a constituent of ginger, has been reported to have anti-inflammatory and anti-oxidant effects on neuronal cells, research regarding the activation of SORL1 has not yet been reported. Here, we aimed to investigate whether 6-shogaol contributes to the increases in SORL1 that are related to Alzheimer's disease (AD).

Phosphatidylcholine (PC) from egg yolk is a bioactive substance with various beneficial effects, including anti-inflammatory and anti-oxidant effects. Recently, this substance has been reported to prevent acute hepatotoxicity. In the present study, we aimed to evaluate the putative protective effect of PC on carbon tetrachloride (CCl)-induced nephrotoxicity in ICR mice.

Purpose: Emotional competence refers to the ability to identify, respond to, and manage one's own and others' emotions. Emotional competence is critical to many functional outcomes, including making and maintaining friends, academic success, and community integration. There appears to be a link between the development of language and the development of emotional competence in children who use speech.

6-Shogaol can be extracted from ginger and has been shown to exert anti-inflammatory and antioxidant activities, which are potentially relevant to the treatment of central nervous system disorders. Oxidative stress and inflammation are closely associated with ischemic injury and can eventually result in neuronal death. The aim of this study was to evaluate if 6-shogaol exerts neuroprotective activity.

Although 6-shogaol, a constituent of ginger, has been reported to have anti-inflammatory and anti-oxidant effects on neuronal cells, the effects of 6-shogaol on Alzheimer's disease (AD) have not yet been investigated. Here we aimed to determine whether 6-shogaol exerts neuroprotective effects against AD. Specifically, we investigated the effects of 6-shogaol on the cysteinyl leukotriene 1 receptor (CysLT1R), a major factor in AD pathogenesis.

Conjugated linoleic acid (CLA) is a group of positional and geometric isomers of conjugated dienoic derivatives of linoleic acid. CLA has been reported to be able to reduce body fat. In this study, we investigated the antidiabetic effect of fermented milk (FM) containing CLA on type II diabetes db/db mice.

The progressive degeneration and ossification of articular chondrocytes are main symptoms in the pathogenesis of osteoarthritis (OA). Several flavonoids may provide an adjunctive alternative for the management of moderate OA in humans. Rutin, a natural flavone derivative (quercetin-3-rhamnosylglucoside), is well known for its potent anti-inflammatory and anti-oxidant properties against oxidative stress.

It has been shown that phosphatidylcholine (PC) extracted from egg yolk possesses a variety of biological activities, such as anti-inflammatory and anti-oxidant effects, and prevents oxidative stress. The aim of this study was to evaluate the hepatoprotective effects of PC against carbon tetrachloride (CCl₄), which is a well-known hepatotoxicant that causes extensive oxidative liver damage, and to investigate the mechanisms involved in this protective effect. Mice were treated with PC (0.

This study evaluated the effectiveness of irradiated porcine tendon xenografts for lateral collateral ligament (LCL) reconstruction. Twenty healthy adult beagle dogs underwent LCL reconstruction using irradiated porcine tendons treated with poly-gamma-glutamic acid. Serological and histological assessments were performed to evaluate host immunological response at 3 and 12 months after surgery.

Background: Alcoholism, which refers to the excessive consumption of alcohol, has deleterious effects on personal and social health worldwide. Oxidative stress evoked by ethanol plays an important role in the pathogenesis of neurodegenerative diseases. Rutin is a bioflavonoid that has been demonstrated to scavenge superoxide radicals.

Prion disorders are progressive neurodegenerative diseases characterized by extensive neuronal loss and accumulation of the abnormal form of the scrapie prion protein (PrP). Rutin is a flavonoid that occurs naturally in plant-derived beverages and foods and is used in traditional and folkloric medicine worldwide. In the present study, we evaluated the protective effects of rutin against PrP fragment (106-126)-induced neuronal cell death.

Chondrocyte apoptosis has been recognized as an important factor in the pathogenesis of osteoarthritis (OA). Hydrogen peroxide (H2O2), which produces reactive oxygen species, reportedly induces apoptosis in chondrocytes. The ginsenoside Rb1 (GRb1) is the principal component in ginseng and has been shown to have a variety of biological activities, such as anti-arthritis, anti-inflammation, and anti-tumor activities.

The abnormal maturation and ossification of articular chondrocytes play a central role in the pathogenesis of osteoarthritis (OA). Inhibiting the enzymatic degradation of the extracellular matrix and maintaining the cellular phenotype are two of the major goals of interest in managing OA. Ginseng is frequently taken orally, as a crude substance, as a traditional medicine in Asian countries.

It has been shown that the accumulation of prion in the cytoplasm can result in neurodegenerative disorders. Synthetic prion peptide 106-126 (PrP) is a glycoprotein that is expressed predominantly by neurons and other cells, including glial cells. Prion-induced chronic neurodegeneration has a substantial inflammatory component, and an increase in the levels of matrix metalloproteinases (MMPs) may play an important role in neurodegenerative development and progression.
