Altered Resting-State Functional Connectivity of the Striatum in Parkinson's Disease after Levodopa Administration

Background Despite improvement in motor symptoms, the effect of dopaminergic medications on cognition in patients with Parkinson’s disease (PD) is less clear. The purpose of this study was to reveal levodopa-induced acute changes in the functional connectivity of the striatum in patients with PD compared with matched untreated patients and healthy volunteers. Methods Twenty-two...

Compromised Wound Healing in Ischemic Type 2 Diabetic Rats

Ischemia is one of the main epidemic factors and characteristics of diabetic chronic wounds, and exerts a profound effect on wound healing. To explore the mechanism of and the cure for diabetic impaired wound healing, we established a type 2 diabetic rat model. We used an 8weeks high fat diet (HFD) feeding regimen followed by multiple injections of streptozotocin (STZ) at a dose...

Conducting polymer hydrogel materials for high-performance flexible solid-state supercapacitors

Different from solid electrodes, conducting polymer hydrogel electrodes swollen with water and ions, can reach contact with the electrolyte solution at the molecular level, which will result in more efficient electrochemical process of supercapacitors. Besides, the inherent soft nature of hydrogel material offers the electrode superior flexibility, which benefits to gain high...

Response of Woodpecker's Head during Pecking Process Simulated by Material Point Method

Prevention of brain injury in woodpeckers under high deceleration during the pecking process has been an intriguing biomechanical problem for a long time. Several studies have provided different explanations, but the function of the hyoid bone, one of the more interesting skeletal features of a woodpecker, still has not been fully explored. This paper studies the relationship...

Selenotranscriptomic Analyses Identify Signature Selenoproteins in Brain Regions in a Mouse Model of Parkinson’s Disease

Genes of selenoproteome have been increasingly implicated in various aspects of neurobiology and neurological disorders, but remain largely elusive in Parkinson’s disease (PD). In this study, we investigated the selenotranscriptome (24 selenoproteins in total) in five brain regions (cerebellum, substantia nigra, cortex, pons and hippocampus) by real time qPCR in a two-phase...

Inhibition of Nischarin Expression Promotes Neurite Outgrowth through Regulation of PAK Activity

Nischarin is a cytoplasmic protein expressed in various organs that plays an inhibitory role in cell migration and invasion and the carcinogenesis of breast cancer cells. We previously reported that Nischarin is highly expressed in neuronal cell lines and is differentially expressed in the brain tissue of adult rats. However, the physiological function of Nischarin in neural...

Severe burn injury in late pregnancy: a case report and literature review

The management of serious burn injuries during pregnancy is an unsolved clinical problem because of the low incidence of this disease. Although it has been documented that the effect of burns on fetal and maternal survival is detrimental, there have been conflicting reports among the different burn centers regarding the mortality of burned pregnant women and the management of...

Analysis of the Relationship between Genomic GC Content and Patterns of Base Usage, Codon Usage and Amino Acid Usage in Prokaryotes: Similar GC Content Adopts Similar Compositional Frequencies Regardless of the Phylogenetic Lineages

The GC contents of 2670 prokaryotic genomes that belong to diverse phylogenetic lineages were analyzed in this paper. These genomes had GC contents that ranged from 13.5% to 74.9%. We analyzed the distance of base frequencies at the three codon positions, codon frequencies, and amino acid compositions across genomes with respect to the differences in the GC content of these...

High microRNA-23a expression in laryngeal squamous cell carcinoma is associated with poor patient prognosis

Background MicroRNA-23a (miR-23a) has been demonstrated to play an important role in the development of several types of cancer, but its role in tumorigenesis of laryngeal carcinoma is still unclear. The aim of this study was to investigate the expression patterns and clinical implications of miR-23a in laryngeal cancer. Methods Quantitative RT-PCR was performed to evaluate the...

Electrochemical reduction of graphene oxide films: Preparation, characterization and their electrochemical properties

Graphene oxide (GO) film was electrochemically reduced by a cyclic voltammetry technique in 6 mol L−1 KOH aqueous solution. Electrochemically reduced graphene oxide (ER-GO) film was characterized by X-ray diffraction, X-ray photoelectron spectroscopy, atomic force microscopy, and Raman spectroscopy. The oxygen content (with the O/C atomic ratio of 1.29%) was significantly...

Paroxetine ameliorates lipopolysaccharide-induced microglia activation via differential regulation of MAPK signaling

Background Paroxetine, a selective serotonin reuptake inhibitor for counteracting depression, has been recently suggested as having a role in prevention of dopaminergic neuronal degeneration in substantia nigra, a hallmark of Parkinson’s disease (PD). The pathogenesis of this type of neurological disorders often involves the activation of microglia and associated inflammatory...

Universal hierarchical symmetry for turbulence and general multi-scale fluctuation systems

Zhen-Su She Zhi-Xiong Zhang Scaling is an important measure of multi-scale fluctuation systems. Turbulence as the most remarkable multi-scale system possesses scaling over a wide range of scales

Assessing Plasma Levels of Selenium, Copper, Iron and Zinc in Patients of Parkinson’s Disease

Trace elements have been recognized to play an important role in the development of Parkinson’s disease (PD). However, it is difficult to precisely identify the relationship between these elements and the progression of PD because of an insufficient number of patients. In this study, quantifications of selenium (Se), copper (Cu), iron (Fe) and zinc (Zn) by atomic absorption...

Nischarin Is Differentially Expressed in Rat Brain and Regulates Neuronal Migration

Nischarin is a protein known to inhibit breast cancer cell motility by regulating the signaling of the Rho GTPase family. However, little is known about its location and function in the nervous system. The aim of the present study was to investigate the regional and cellular expression and functions of Nischarin in the adult rodent brain. As assessed by real-time PCR, Western...

Mercury-induced toxicity of rat cortical neurons is mediated through N-methyl-D-Aspartate receptors

BackgroundMercury is a well-known neurotoxin implicated in a wide range of neurological or psychiatric disorders including autism spectrum disorders, Alzheimer’s disease, Parkinson’s disease, epilepsy, depression, mood disorders and tremor. Mercury-induced neuronal degeneration is thought to invoke glutamate-mediated excitotoxicity, however, the underlying mechanisms remain...
