Chinese Herbal Medicine Glycyrrhiza inflataReduces Aβ Aggregation and Exerts Neuroprotection through Anti-Oxidation and Anti-Inflammation.

Amyloid [Formula: see text] (A[Formula: see text]) plays a major role in the pathogenesis of Alzheimer's disease (AD). The accumulation of misfolded A[Formula: see text] causes oxidative and inflammatory damage leading to apoptotic cell death. Chinese herbal medicine (CHM) has been widely used in clinical practice to treat neurodegenerative diseases associated with oxidative stress and neuroinflammation.

Visuomotor adaptability in older adults with mild cognitive decline.

The current study examined the augmentation of error feedback on visuomotor adaptability in older adults with varying degrees of cognitive decline (assessed by the Montreal Cognitive Assessment; MoCA). Twenty-three participants performed a center-out computerized visuomotor adaptation task when the visual feedback of their hand movement error was presented in a regular (ratio=1:1) or enhanced (ratio=1:2) error feedback schedule. Results showed that older adults with lower scores on the MoCA had less adaptability than those with higher MoCA scores during the regular feedback schedule.

Medicinal herbs Oenanthe javanica (Blume) DC., Casuarina equisetifolia L. and Sorghum bicolor (L.) Moench protect human cells from MPP damage via inducing FBXO7 expression.

Background: The F-box protein 7 (FBXO7) mutations have been identified in families with early-onset parkinsonism and pyramidal tract signs, and designated as PARK15. In addition, FBXO7 mutations were found in typical and young onset Parkinson's disease (PD). Evidence has also shown that FBXO7 plays an important role in the development of dopaminergic neurons and increased stability and overexpression of FBXO7 may be beneficial to PD.

The potential of synthetic indolylquinoline derivatives for Aβ aggregation reduction by chemical chaperone activity.

Alzheimer's disease (AD) is the most prevalent form of dementia associated with progressive cognitive decline and memory loss. Extracellular β-amyloid (Aβ) is a major constituent of senile plaques, one of the pathological hallmarks of AD. Aβ deposition causes neuronal death via a number of possible mechanisms such as increasing oxidative stress.

Novel Lactulose and Melibiose Targeting Autophagy to Reduce PolyQ Aggregation in Cell Models of Spinocerebellar Ataxia 3.

Trehalose, a chemical chaperone and mTOR-independent autophagy enhancer, has shown promise in models of Huntington's disease, Parkinson's disease and tauopathies. In this study, two trehalase analogs, lactulose and melibiose, were examined for their potentials in spinocerebellar ataxia treatment. Using a SCA3 ATXN3/Q75-GFP cell model, we found that the ATXN3/Q75 aggregation was significantly prohibited by lactulose and melibiose because of their abilities to up-regulate autophagy.

FBXO7 Y52C polymorphism as a potential protective factor in Parkinson's disease.

To identify new variants, we sequenced FBXO7 cDNA in 80 Taiwanese early onset PD patients (age at onset ≤ 50) and only two known variants, Y52C (c.155A>G) and M115I (c.

Examining the relationship between motor assessments and handwriting consistency in children with and without probable developmental coordination disorder.

Children with Developmental Coordination Disorder (DCD) often experience difficulties in handwriting. The current study examined the relationships between three motor assessments and the spatial and temporal consistency of handwriting. Twelve children with probable DCD and 29 children from 7 to 12 years who were typically developing wrote the lowercase letters "e" and "l" in cursive and printed forms repetitively on a digitizing tablet.

Circadian regulation of permethrin susceptibility by glutathione S-transferase (BgGSTD1) in the German cockroach (Blattella germanica).

The daily susceptibility rhythm to permethrin and the expression level of the delta class glutathione S-transferase (BgGSTD1) gene were investigated in Blattella germanica. Male cockroaches were exposed to the same concentration of permethrin at different times in a light-dark cycle, and results showed that the highest resistance occurred at night. Furthermore, the circadian rhythmicity of permethrin susceptibility was demonstrated by the highest resistance at subjective night under constant darkness.

ADHD-related symptoms, emotional/behavioral problems, and physical conditions in Taiwanese children with epilepsy.

Background/purpose: Little is known about whether Asian children with epilepsy have more attention-deficit hyperactivity disorder (ADHD)-related symptoms, emotional/ behavioral problems, and physical conditions compared with those described in Western studies. The authors investigated the rates of ADHD-related symptoms, emotional/behavioral problems, and physical conditions among pediatric patients with epilepsy.

Methods: We recruited 61 patients with epilepsy, aged 6-16 years, and 122 age-, sex-, and parental education-matched school controls.

Motor skill learning in children with Developmental Coordination Disorder.

Children with Developmental Coordination Disorder (DCD) are characterized as having motor difficulties and learning impairment that may last well into adolescence and adulthood. Although behavioral deficits have been identified in many domains such as visuo-spatial processing, kinesthetic perception, and cross-modal sensory integration, recent studies suggested that the functional impairment of certain brain areas, such as cerebellum and basal ganglia, are the underlying causes of DCD. This review focuses on the "motor learning deficits" in DCD and their possible neural correlates.

Correlation between bio-hydrogen production and polyhydroxybutyrate (PHB) synthesis by Rhodopseudomonas palustris WP3-5.

The aim of this study was to determine the competition between H(2) production and polyhydroxybutyrate (PHB) accumulation of Rhodopseudomonas palustris WP3-5 when grown on six different substrates. From the results, strain WP3-5 can utilize acetate, propionate, malate, and lactate to produce H(2) but can only synthesize PHB on acetate and propionate. The substrate conversion efficiency (SCE) on acetate and propionate increased significantly after the maximum PHB content was achieved, illustrating a competition for reducing power when PHB synthesis occurred.

Mitochondrial dysfunction and oxidative stress contribute to the pathogenesis of spinocerebellar ataxia type 12 (SCA12).

Spinal cerebellar ataxia type 12 (SCA12) has been attributed to the elevated expression of ppp2r2b. To better elucidate the pathomechanism of the neuronal disorder and to search for a pharmacological treatment, Drosophila models of SCA12 were generated by overexpression of a human ppp2r2b and its Drosophila homolog tws. Ectopic expression of ppp2r2b or tws caused various pathological features, including neurodegeneration, apoptosis, and shortened life span.
