Hericerin derivatives activates a pan-neurotrophic pathway in central hippocampal neurons converging to ERK1/2 signaling enhancing spatial memory.

The traditional medicinal mushroom Hericium erinaceus is known for enhancing peripheral nerve regeneration through targeting nerve growth factor (NGF) neurotrophic activity. Here, we purified and identified biologically new active compounds from H. erinaceus, based on their ability to promote neurite outgrowth in hippocampal neurons.

Variations in home range and core area of red-backed voles (Myodes regulus) in response to various ecological factors.

The characteristics of animal distribution are determined by interactions between the resource requirements of animals and ecological factors. This study sought to evaluate the effects of diverse ecological factors on the home range and core area of red-backed voles (Myodes regulus) in a natural deciduous forest located on Mt. Gariwang, Pyeongchang and Jeongseon, South Korea.

Total Synthesis of Isohericerinol A and Its Analogues to Access Their Potential Neurotrophic Effects.

The secondary metabolites from are well-known to have neurotrophic and neuroprotective effects. Isohericerinol A (), isolated by our colleagues from its fruiting parts has a strong ability to increase the nerve growth factor secretion in C6 glioma cells. The current work describes the total synthesis of and its regioisomer in a few steps.

A Mixture of . Leaf and . Fruit Extract Attenuates Scopolamine-Induced Memory Impairments in Mice.

Alzheimer's disease (AD) is a neurodegenerative disease that is characterized by loss of memory and cognitive impairment dysfunction of the cholinergic nervous system. In cholinergic dysfunction, it is well known that impaired cAMP response element-binding protein (CREB) and brain-derived neurotrophic factor (BDNF) signaling are major pathological markers and are some of the strategies for the development of AD therapy. Therefore, this study is aimed at evaluating whether a mixture comprising .

Neurotrophic isoindolinones from the fruiting bodies of Hericium erinaceus.

Four compounds, hericerin (1), isohericerinol A (2), N-de-phenylethyl isohericerin (3) and corallocin A (4) were isolated from the fruiting bodies of Hericium erinaceus, a lion's mane mushroom (Hericiaceae). Among them, isohericerinol A (2) was newly reported in nature. Further investigation of the neurotrophic effect of isolated compounds demonstrated that isohericerinol A (2) strongly increased the nerve growth factor (NGF) production in C6 glioma cells followed by corallocin A (4) and hericerin (1).

Enzyme Treatment Alters the Anti-Inflammatory Activity of the Water Extract of Wheat Germ In Vitro and In Vivo.

Wheat germ is rich in quinones that exist as glycosides. In this study, we used Celluclast 1.5L to release the hydroxyquinones, which turn into benzoquinone, and prepared the water extract from enzyme-treated wheat germ (EWG).

Anti-Inflammatory Activity of Citric Acid-Treated Wheat Germ Extract in Lipopolysaccharide-Stimulated Macrophages.

Until recently, fermentation was the only processing used to improve the functionality of wheat germ. The release of 2,6-dimethoxy-1,4-benzoquinone (DMBQ) from hydroquinone glycosides during the fermentation process is considered a marker of quality control. Here, we treated wheat germ extract with citric acid (CWG) to release DMBQ and examined the anti-inflammatory activity of this extract using a lipopolysaccharide-activated macrophage model.

Influence of tree thinning on the abundance of mammals in a Japanese larch plantation.

We examined the influence of tree thinning on the abundance of mammals in a Japanese larch plantation in Mt Gariwang, Pyeongchang, South Korea. In 2014 and 2015, from April to October, we recorded the presence of tracks as a proxy for abundance, for the following seven mammalian species: Korean hare , raccoon dog , Siberian weasel , Eurasian badger , water deer , roe deer , and wild boar . We also assessed how the intensity of tree thinning affected vegetation cover; there were significant differences in number of standing trees, basal area, coverage of vegetation layers, and number and volume of downed trees among the control, moderately thinned, and intensively thinned stands.

Behaviors and body weight of suckling piglets in different social environments.

Objective: This study was conducted to characterize the behaviors and the body weight of suckling piglets in different social environments.

Methods: Two groups of sows and suckling piglets housed either in individual farrowing crates in separate pens (1.8×2.

Identification of Water Bodies in a Landsat 8 OLI Image Using a J48 Decision Tree.

Water bodies are essential to humans and other forms of life. Identification of water bodies can be useful in various ways, including estimation of water availability, demarcation of flooded regions, change detection, and so on. In past decades, Landsat satellite sensors have been used for land use classification and water body identification.

New Quality Control Algorithm Based on GNSS Sensing Data for a Bridge Health Monitoring System.

This research introduces an improvement plan for the reliability of Global Navigation Satellite System (GNSS) positioning solutions. It should be considered the most suitable methodology in terms of the adjustment and positioning of GNSS in order to maximize the utilization of GNSS applications. Though various studies have been conducted with regards to Bridge Health Monitoring System (BHMS) based on GNSS, the outliers which depend on the signal reception environment could not be considered until now.

Enzymatically-Processed Wheat Bran Enhances Macrophage Activity and Has in Vivo Anti-Inflammatory Effects in Mice.

Wheat bran is a rich source of dietary fiber, of which arabinoxylan is the most abundant non-starch polysaccharide. Arabinoxylan has been known to exert in vivo immunological activities. Based on prior findings, we pretreated wheat bran with enzymatic hydrolysis to increase the release of soluble arabinoxylan and investigated whether oral administration of wheat bran altered macrophage activity in a mouse model.

Behavioral Characteristics of Weaned Piglets Mixed in Different Groups.

With regard to animal welfare concerns, behavioral information of weaned and mixed piglets is great interest in swine production. The aim of this study was to demonstrate the change in behavior of weaned piglets over time in two different groups (littermates and piglets from different litters) after mixing. Two weaned groups of piglets (72 individuals in all) housed either with littermates or with foreign piglets (6 individuals in 1.

Effects of Mixing on the Aggressive Behavior of Commercially Housed Pigs.

In this study, we investigated the effects of mixing on the aggressive behavior of commercially housed pigs. The behavioral patterns of 36 groups of pigs (a total of 360 animals) were observed over 3 consecutive days directly after weaning (25±1.2 days of age), and 25 and 50 days later with the aid of video technology.
