Does Cognitive-Physical Dual-Task Training Have Better Clinical Outcomes than Cognitive Single-Task Training Does? A Single-Blind, Randomized Controlled Trial.

Purpose: At present, there is a controversy regarding the effect of dual-task training on improving the cognitive function of people with mild cognitive impairment (MCI). This study was to develop and verify the effects of the cognitive-physical dual-task training program on the executive function of older adults with MCI.

Method: Participants were randomly allocated to the experimental group (EG) receiving cognitive-physical dual-task training (n = 21) or the control group (CG) receiving cognitive single-task training (n = 21).

3,5,6,7,8,3',4'-Heptamethoxyflavone, a Citrus Flavonoid, Inhibits Collagenase Activity and Induces Type I Procollagen Synthesis in HDFn Cells.

fruits contain various types of flavonoids with powerful anti-aging and photoprotective effects on the skin, and have thus been attracting attention as potential, efficacious skincare agents. Here, we aimed to investigate the chemical composition of and its protective effects on photoaging. We isolated and identified a bioactive compound, 3,5,6,7,8,3',4'-heptamethoxyflavone (HMF), from peels using ethanol extraction and hexane fractionation.

Evaluation of recurrence in gastric carcinoma: Comparison of contrast-enhanced computed tomography and positron emission tomography/computed tomography.

Aim: To compare the value of contrast-enhanced abdominal computed tomography (CT) and fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) for detecting gastric carcinoma recurrence.

Methods: We retrospectively examined data from 2475 patients who underwent both contrast-enhanced abdominal CT and FDG PET/CT for the surveillance of gastric carcinoma curative resection. Patients had an interval of less than 1 mo between their CT and PET/CT scans.

Effects of Ganodermanondiol, a New Melanogenesis Inhibitor from the Medicinal Mushroom Ganoderma lucidum.

, a species of the Basidiomycetes class, has been attracting international attention owing to its wide variety of biological activities and great potential as an ingredient in skin care cosmetics including "skin-whitening" products. However, there is little information available on its inhibitory effect against tyrosinase activity. Therefore, the objectives of this study were to investigate the chemical composition of and its inhibitory effects on melanogenesis.

Transcriptome and Gene Ontology (GO) Enrichment Analysis Reveals Genes Involved in Biotin Metabolism That Affect L-Lysine Production in Corynebacterium glutamicum.

Corynebacterium glutamicum is widely used for amino acid production. In the present study, 543 genes showed a significant change in their mRNA expression levels in L-lysine-producing C. glutamicum ATCC21300 than that in the wild-type C.

LRRK2 G2019S mutation attenuates microglial motility by inhibiting focal adhesion kinase.

In response to brain injury, microglia rapidly extend processes that isolate lesion sites and protect the brain from further injury. Here we report that microglia carrying a pathogenic mutation in the Parkinson's disease (PD)-associated gene, G2019S-LRRK2 (GS-Tg microglia), show retarded ADP-induced motility and delayed isolation of injury, compared with non-Tg microglia. Conversely, LRRK2 knockdown microglia are highly motile compared with control cells.

Multi-axis shoulder abduction splint in acute burn rehabilitation: a randomized controlled pilot trial.

Objective: The traditional thermoplastic aeroplane splint for axillary burn contracture is heavy, uncomfortable, and time consuming and difficult to put on and off. The present study tested the effectiveness of a newly designed multi-axis shoulder abduction splint with an easy-to-change angle.

Design: Randomized controlled parallel assessor blinded pilot.

Suppression of miR-155 Expression in IFN-γ-Treated Astrocytes and Microglia by DJ-1: A Possible Mechanism for Maintaining SOCS1 Expression.

Previously, we reported that DJ-1, encoded by a Parkinson's disease (PD)-associated gene, inhibits expression of proinflammatory mediators in interferon-gamma (IFN-γ)-treated astrocytes and microglia through inhibition of STAT1 activation. Here, using microglia and astrocytes cultured from wild-type (WT) and DJ-1-knockout (KO) mouse brains, we examined how DJ-1 regulates suppressor of cytokine signaling 1 (SOCS1), a negative feedback regulator of STAT1 (signal transducer and activator of transcription) that is also induced by STAT1. We found that IFN-γ significantly increased SOCS1 mRNA expression in WT microglia and astrocytes, but not in KO cells, although STAT1 was highly activated in these latter cells.

DJ-1 facilitates the interaction between STAT1 and its phosphatase, SHP-1, in brain microglia and astrocytes: A novel anti-inflammatory function of DJ-1.

Parkinson's disease (PD) is a progressive neurodegenerative movement disorder caused by the death of dopaminergic neurons in the substantia nigra. Importantly, altered astrocyte and microglial functions could contribute to neuronal death in PD. In this study, we demonstrate a novel mechanism by which DJ-1 (PARK7), an early onset autosomal-recessive PD gene, negatively regulates inflammatory responses of astrocytes and microglia by facilitating the interaction between STAT1 and its phosphatase, SHP-1 (Src-homology 2-domain containing protein tyrosine phosphatase-1).

Spatial and temporal correlation in progressive degeneration of neurons and astrocytes in contusion-induced spinal cord injury.

Background: Traumatic spinal cord injury (SCI) causes acute neuronal death followed by delayed secondary neuronal damage. However, little is known about how microenvironment regulating cells such as microglia, astrocytes, and blood inflammatory cells behave in early SCI states and how they contribute to delayed neuronal death.

Methods: We analyzed the behavior of neurons and microenvironment regulating cells using a contusion-induced SCI model, examining early (3-6 h) to late times (14 d) after the injury.

Impaired inflammatory responses in murine Lrrk2-knockdown brain microglia.

LRRK2, a Parkinson's disease associated gene, is highly expressed in microglia in addition to neurons; however, its function in microglia has not been evaluated. Using Lrrk2 knockdown (Lrrk2-KD) murine microglia prepared by lentiviral-mediated transfer of Lrrk2-specific small inhibitory hairpin RNA (shRNA), we found that Lrrk2 deficiency attenuated lipopolysaccharide (LPS)-induced mRNA and/or protein expression of inducible nitric oxide synthase, TNF-α, IL-1β and IL-6. LPS-induced phosphorylation of p38 mitogen-activated protein kinase and stimulation of NF-κB-responsive luciferase reporter activity was also decreased in Lrrk2-KD cells.

Dimethylsulfoxide (DMSO) induces downregulation of heme oxygenase-1 (HO-1) in HL-60 cells: involvement of HO-1 in HL-60 cell differentiation.

Heme oxygenase-1 (HO-1), an inducible enzyme with broad tissue expression, is wel1-regulated in response to hematopoietic stress and preserves vascular homeostasis. We investigated the involvement of HO-1 in HL-60 cell differentiation. Dimethyl sulfoxide (DMSO) completely decreased HO-1 expression in a time-dependent manner, but clearly induced HL-60 cell differentiation, as evidenced by a marked increase in CD11b expression.

Adaptive synthesis of distance fields.

We address the computational resource requirements of 3D example-based synthesis with an adaptive synthesis technique that uses a tree-based synthesis map. A signed-distance field (SDF) is determined for the 3D exemplars, and then new models can be synthesized as SDFs by neighborhood matching. Unlike voxel synthesis approach, our input is posed in the real domain to preserve maximum detail.

Uridine 5'-diphosphate induces chemokine expression in microglia and astrocytes through activation of the P2Y6 receptor.

Chemokines play critical roles in inflammation by recruiting inflammatory cells to injury sites. In this study, we found that UDP induced expression of chemokines CCL2 (MCP-1) and CCL3 (MIP-1α) in microglia, astrocytes, and slice cultures by activation of P2Y(6). Interestingly, CCL2 was more highly expressed than CCL3.

Astrocytes in injury states rapidly produce anti-inflammatory factors and attenuate microglial inflammatory responses.

Microglia are known to be a primary inflammatory cell type in the brain. However, microglial inflammatory responses are attenuated in the injured brain compared to those in cultured pure microglia. In the present study, we found that astrocytes challenged by oxygen-glucose deprivation (OGD) or H(2) O(2) released soluble factor(s) and attenuated microglial inflammatory responses.

A novel Ca2+/calmodulin antagonist HBC inhibits angiogenesis and down-regulates hypoxia-inducible factor.

Recent reports have shown that Ca(2+)/calmodulin (Ca(2+)/CaM) signaling plays a crucial role in angiogenesis. We previously developed a new Ca(2+)/CaM antagonist, HBC (4-{3,5-bis-[2-(4-hydroxy-3-methoxyphenyl)ethyl]-4,5-dihydropyrazol-1-yl}benzoic acid), from a curcumin-based synthetic chemical library. Here, we investigated its anti-angiogenic activity and mode of action.

Cordycepin inhibits UVB-induced matrix metalloproteinase expression by suppressing the NF-kappaB pathway in human dermal fibroblasts.

Cordycepin (3-deoxyadenosine) has been shown to exhibit many pharmacological activities, including anti-cancer, anti-inflammatory, and anti-infection activities. However, the anti-skin photoaging effects of cordycepin have not yet been reported. In the present study, we investigated the inhibitory effects of cordycepin on matrix metalloproteinase-1 (MMP-1) and -3 expressions of the human dermal fibroblast cells.

Adenosine induces hemeoxygenase-1 expression in microglia through the activation of phosphatidylinositol 3-kinase and nuclear factor E2-related factor 2.

Adenosine, a purine nucleoside, has been reported to suppress the inflammatory responses of microglia in the brain. However, the underlying mechanisms of its anti-inflammatory action are unclear at present. Here we show that adenosine reduces the increase in intracellular reactive oxygen species (ROS) through expression of an antioxidant enzyme, hemeoxygenase-1 (HO-1).
