Network analysis of microRNAs, transcription factors, and target genes involved in axon regeneration.

Axon regeneration is crucial for recovery from neurological diseases. Numerous studies have identified several genes, microRNAs (miRNAs), and transcription factors (TFs) that influence axon regeneration. However, the regulatory networks involved have not been fully elucidated.

Network analysis identifies common genes associated with obesity in six obesity-related diseases.

Obesity has been reported to be associated with many diseases. However, common obesity-induced biological processes have not been evaluated across these diseases. We identified genes associated with obesity and obesity-related diseases, and used them to construct protein‒protein interaction networks.

Identification of neuron-related genes for cell therapy of neurological disorders by network analysis.

Bone mesenchymal stem cells (BMSCs) differentiated into neurons have been widely proposed for use in cell therapy of many neurological disorders. It is therefore important to understand the molecular mechanisms underlying this differentiation. We screened differentially expressed genes between immature neural tissues and untreated BMSCs to identify the genes responsible for neuronal differentiation from BMSCs.

Anti-Interleukin-1 Beta/Tumor Necrosis Factor-Alpha IgY Antibodies Reduce Pathological Allergic Responses in Guinea Pigs with Allergic Rhinitis.

This study aims to determine whether the combined blockade of IL-1β and TNF-α can alleviate the pathological allergic inflammatory reaction in the nasal mucosa and lung tissues in allergic rhinitis (AR) guinea pigs. Healthy guinea pigs treated with saline were used as the healthy controls. The AR guinea pigs were randomly divided into (1) the AR model group treated with intranasal saline; (2) the 0.

Neuroprotective effects of polysaccharides against neuronal apoptosis induced by hypoxia.

polysaccharides (RDPS) are the primary active ingredient of , which is a traditional Chinese medicine. RDPS have previously been shown to scavenge reactive oxygen species, and protect against D-galactose-induced mimetic aging. The present study aimed to investigate the neuroprotective effects of RDPS against hypoxia-induced neuronal cell apoptosis.

[Effect of GABA(B) Receptor Signal to Corticosterone-induced Neuron Apoptosis].

Objective: To investigate whether corticosterone results in neuron apoptosis through regulating γ-aminobutyric acid (GABA) receptor.

Methods: In vivo: the hyperglycemic rat model with applying chronic restraint stress to healthy male SD rats (3 months) was established, after paraffin embedding the brain was sliced, and the level of neuron apoptosis was tested by detecting active Caspase-3 with immune-histochemical staining and TUNEL. The level of corticosterone in serum was detected by using ELISA.

[The distribution of caspase-3 positive apoptotic cells in 18 months old SD rat's brainstem compared with that in 3 months rat].

Objective: To study whether there is apoptosis in brainstem neurons while aging by oberving the distribution of Caspase-3 positive apoptotic cells in in brainstem of young and old SD rats.

Methods: Healthy male SD rats were divided into 2 groups (3 and 18 month-old respectively), 3 rats each group. Brainstem specimens were treated followed the brainstem's common paraffin embedding, sectioning and HE staining procedures (sections were 6 μm in thickness).

Orally administered DNA vaccine delivery by attenuated Salmonella typhimurium targeting fetal liver kinase 1 inhibits murine Lewis lung carcinoma growth and metastasis.

The vascular endothelial growth factor (VEGF) receptor 2 (VEGFR-2), also called fetal liver kinase 1 (FLK1) in mice and kinase insert domain receptor (KDR) in humans, is an endothelial cell specific receptor tyrosine kinase that mediates lung cancer angiogenesis. We hypothesized that an active immunotherapy approach targeting FLK1 may inhibit lung cancer growth and metastasis. To test this hypothesis, we evaluated whether immune responses to FLK1 could be elicited in mice by immunization with an orally administered DNA vaccine encoding the extracellular domain (ECD) of FLK1 (pcDNA3.

[Staining improvement for Blastocystis hominis specimen].

Schaudinn solution was used to fix the Blastocystis hominis specimen and an improved Harris hematoxylin staining was applied to stain it. The method shows clearer internal structure of the parasite, simpler and less time-consuming than the traditional iron hematoxylin solution.

[Investigations on cordycepin production by solid culture of Cordyceps militaris].

An efficient method to produce cordycepin by solid culture using Cordyceps militaris was investigated in this study. Firstly, the changes of cordycepin during various growing periods of solid culture using 5 strains of C. militaris were detected, the best strain and optimal growing period for cordycepin production were determined.

[Change rate in bone cells of mice].

Objective: To study the anti-mutation action of acupuncture and moxibustion.

Methods: Mice were randomly divided into 6 groups, group 1 (normal control group), group 2 (positive control group), group 3 (prevention group I), group 4 (prevention group II ), group 5 (treatment group I) and group 6 (treatment group II). The mice in the group 2-6 were treated by cyclophosphamide (ip, 50 mg/kg body weight), and in the 3'-6 groups were given acupuncture at "Zusanli" (ST 36) and moxibustion at "Guanyuan" (CV 4).
