Composition, characteristics, and treatment technologies of condensable particulate matter present in flue gas emitted by coking plants in China.

To study the total particulate matter (TPM) in flue gas emitted by coking plants, a sampling system that could be used to collect filterable particulate matter (FPM) and condensable particulate matter (CPM) was designed and developed based on Method 202 recommended by the U.S. Environmental Protection Agency in 2017 and HJ 836-2017 issued by China.

Correlation between sarcopenia index and cognitive function in older adult women: A cross-sectional study using NHANES data.

Objectives: The Sarcopenia Index (SI) has the potential as a biomarker for sarcopenia, which is characterized by muscle loss. There is a clear association between sarcopenia and cognitive impairment. However, the relationship between SI and cognitive impairment is yet to be fully understood.

Characteristics of microplastics in the atmosphere of Anyang City.

In order to clarify the characteristics of microplastics in the atmosphere of Anyang city, TSP, PM, and PM samples are collected when the ambient air quality is good, slightly polluted, and severely polluted. After pretreatment, the physical and chemical characteristics are observed and identified by using stereomicroscope and micro-infrared spectrometer. The results show that the average abundance of microplastics is 0.

Acoustic stimulation during sleep improves cognition and ameliorates Alzheimer's disease pathology in APP/PS1 mice.

Nonpharmacological therapies for Alzheimer's disease (AD) have become a popular research topic, and acoustic stimulation during sleep is one such promising strategy for the clinical treatment of AD. Some animal experiments have illustrated that acoustic stimulation at a specific frequency can ameliorate AD-related pathology or improve cognition in mice, but these studies did not explore the effective time window of auditory stimulation. Here, we explored the effects of acoustic stimulation during wakefulness and acoustic stimulation during sleep on cognition and AD-related pathology in APP/PS1 mice and the underlying mechanisms.

Immunological Behavior Analysis of Muscle Cells under IFN-γ Stimulation in Vitro and in Vivo.

Muscle cells could serve as antigen-presenting cells, and participate in the activation of immune response. Immunological characteristics of muscle cells, and their capacities to equip themselves with immunorelevant molecules, remain to be elucidated. In this study, we investigated the immunological properties of myoblasts and differentiated myotubes in vitro and in vivo, under the IFN-γ induced inflammatory condition.

Calcium/Calmodulin-Dependent Protein Kinase IV Mediates IFN-γ-Induced Immune Behaviors in Skeletal Muscle Cells.

Background/aims: Whether calcium/calmodulin-dependent protein kinase IV (CaMKIV) plays a role in regulating immunologic features of muscle cells in inflammatory environment, as it does for immune cells, remains mostly unknown. In this study, we investigated the influence of endogenous CaMKIV on the immunological characteristics of myoblasts and myotubes received IFN-γ stimulation.

Methods: C2C12 and murine myogenic precursor cells (MPCs) were cultured and differentiated in vitro, in the presence of pro-inflammatory IFN-γ.

In vivo immuno-reactivity analysis of the porous three-dimensional chitosan/SiO and chitosan/SiO /hydroxyapatite hybrids.

Inorganic/organic hybrid silica-chitosan (CS) scaffolds have promising potential for bone defect repair, due to the controllable mechanical properties, degradation behavior, and scaffold morphology. However, the precise in vivo immuno-reactivity of silica-CS hybrids with various compositions is still poorly defined. In this study, we fabricated the three-dimensional (3D) interconnected porous chitosan-silica (CS/SiO ) and chitosan-silica-hydroxyapatite (CS/SiO /HA) hybrids, through sol-gel process and 3D plotting skill, followed by the naturally or freeze drying separately.

Calcium/Calmodulin-Dependent Protein Kinase IV (CaMKIV) Mediates Acute Skeletal Muscle Inflammatory Response.

The objective of this study is to investigate the role of Calmodulin-dependent protein kinase IV (CaMKIV) in Cardiotoxin (CTX)-induced mice muscle inflammation. CTX injection i.m.
