Lipopolysaccharide binding protein resists hepatic oxidative stress by regulating lipid droplet homeostasis.

Oxidative stress-induced lipid accumulation is mediated by lipid droplets (LDs) homeostasis, which sequester vulnerable unsaturated triglycerides into LDs to prevent further peroxidation. Here we identify the upregulation of lipopolysaccharide-binding protein (LBP) and its trafficking through LDs as a mechanism for modulating LD homeostasis in response to oxidative stress. Our results suggest that LBP induces lipid accumulation by controlling lipid-redox homeostasis through its lipid-capture activity, sorting unsaturated triglycerides into LDs.

The epilepsy and intellectual disability-associated protein TBC1D24 regulates the maintenance of excitatory synapses and animal behaviors.

Perturbation of synapse development underlies many inherited neurodevelopmental disorders including intellectual disability (ID). Diverse mutations on the human TBC1D24 gene are strongly associated with epilepsy and ID. However, the physiological function of TBC1D24 in the brain is not well understood, and there is a lack of genetic mouse model that mimics TBC1D24 loss-of-function for the study of animal behaviors.

[Comparison of contents of three active ingredients in Bletilla striata from different sources].

In order to understand the difference of contents of coelonin,batatasin Ⅲ and 3'-O-methylbatatasin Ⅲ in 60 different sources of Bletilla striata planted under the same conditions. UPLC method was used and the analysis was performed on a Waters ACQUITY UPLC BEH C18 column( 2. 1 mm×100 mm,1.

The Positive Effects of Viewing Gardens for Persons with Dementia.

Dementia is highly prevalent among the worldwide elderly population. Only a small number of the currently marketed drugs are effective in controlling its symptoms, and none has any effect on its progression. Further, as the condition advances, even these pharmaceuticals lose their efficiency, and new research into interventions that might improve the life quality of patients at the end stage of dementia and their families is increasingly rare.

Ibuprofen prevents progression of ataxia telangiectasia symptoms in ATM-deficient mice.

Background: Inflammation plays a critical role in accelerating the progression of neurodegenerative diseases, such as Alzheimer's disease (AD) and ataxia telangiectasia (A-T). In A-T mouse models, LPS-induced neuroinflammation advances the degenerative changes found in cerebellar Purkinje neurons both in vivo and in vitro. In the current study, we ask whether ibuprofen, a non-steroidal anti-inflammatory drug (NSAID), can have the opposite effect and delay the symptoms of the disease.

Application of Human-Induced Pluripotent Stem Cells (hiPSCs) to Study Synaptopathy of Neurodevelopmental Disorders.

Synapses are the basic structural and functional units for information processing and storage in the brain. Their diverse properties and functions ultimately underlie the complexity of human behavior. Proper development and maintenance of synapses are essential for normal functioning of the nervous system.

The Power of Traditional Design Techniques: The Effects of Viewing a Japanese Garden on Individuals With Cognitive Impairment.

Purpose: This study is to examine how viewing a Japanese garden affects Japanese patients with dementia.

Background: In a previous study, authors explored the effect on individuals with Alzheimer's disease of viewing an indoor Japanese garden at a nursing home in the United States and reported that viewing the garden significantly reduced the heart rate, evoked short-term and long-term memories, and improved behavioral symptoms. However, it was unclear whether these effects were caused by the design of Japanese garden or unfamiliarity of the design to Caucasians.

Neurons in Vulnerable Regions of the Alzheimer's Disease Brain Display Reduced ATM Signaling.

Ataxia telangiectasia (A-T) is a multisystemic disease caused by mutations in the ATM (A-T mutated) gene. It strikes before 5 years of age and leads to dysfunctions in many tissues, including the CNS, where it leads to neurodegeneration, primarily in cerebellum. Alzheimer's disease (AD), by contrast, is a largely sporadic neurodegenerative disorder that rarely strikes before the 7th decade of life with primary neuronal losses in hippocampus, frontal cortex, and certain subcortical nuclei.
