Application of Antibody Fragments Against Aβ With Emphasis on Combined Application With Nanoparticles in Alzheimer's Disease.

Alzheimer's disease (AD) is one of the most common neurodegenerative diseases and accumulating evidences suggest a key role of amyloid-β (Aβ) peptide in the pathogenesis of AD. According to the amyloid cascade hypothesis, the imbalance of producing and clearing Aβ is the beginning of neurodegeneration and dementia. Consequently, immunotherapy becomes popular through using antibodies against Aβ.

The influences of TGF-β1 upon the human adenocarcinoma cell of lung A549 and cellular immunity.

Background: The cellular immunity of lung cancer patients is mainly the immune response of T cells, which plays an important role in tumour cell killing and immune surveillance. Transforming growth factor 1 (TGF-β1) is secreted by tumour cells that can suppress the immune response and is an important group of immune down-regulation factors. Our study aims to investigate the effect of TGF-β1 on the morphology and cellular immune function of A549 and peripheral blood mononuclear cells (PBMCs).

Neuronal NMDAR Currents of the Hippocampus and Learning Performance in Autoimmune Anti-NMDAR Encephalitis and Involvement of TNF-α and IL-6.

Among autoimmune encephalitis, patients with anti-N-methyl D- aspartate receptor (NMDAR) encephalitis typically present epileptic seizures, memory deficits and psychiatric symptoms. However, the signal mechanisms leading to the functional disorders of autoantibodies are largely unclear. In this study, anti-NMDAR antibody was administered into dentate gyri against the NR1 subunit of the NMDAR.

Effect of miR-1244 on cisplatin-treated non-small cell lung cancer via MEF2D expression.

The aim of this study was to investigate the function of miR-1244 in cisplatin-treated non-small cell lung cancer (NSCLC). The results of quantitative PCR analysis revealed that the expression levels of miR-1244 in cisplatin‑treated A549 and NCI-H522 human lung cancer cell lines were lower than those in untreated A549 and NCI-H522 cells. Similarly, the expression level of miR-1244 in NSCLC tissue samples from cisplatin-treated patients was also lower than that in non-cisplatin-treated NSCLC patients.

[Expression profile of miR-501-5p in lung adenocarcinoma patients from Xuanwei area].

Objective: To investigate the relationship between miR-501-5p expression and the clinicopathological factors in patients with lung adenocarcinoma in Xuanwei area.

Methods: Surgical specimens of lung adenocarcinoma and paired adjacent tissues from 24 patients with lung adenocarcinoma from Xuanwei area were examined for miR-501-5p expression using microRNA microarray technique and qPCR. Chi-square test was used to analyze the association of miR-501-5P expression with the clinicopathological characteristics of the patients.

[Specific microRNA expression profiles of lung adenocarcinoma in Xuanwei region and bioinformatic analysis for predicting their target genes and related signaling pathways].

Objective: To identify differentially expressed microRNAs (miRNAs) related to lung adenocarcinoma in Xuanwei region and predict their target genes and related signaling pathways based on bioinformatic analysis.

Methods: High-throughput microarray assay was performed to detect miRNA expression profiles in 34 paired human lung adenocarcinoma and adjacent normal tissues (including 24 cases in Xuanwei region and 10 in other regions). Gene ontology and KEGG pathway analyses were used to predict the target genes and the regulatory signaling pathways.

Cerebral mTOR signal and pro-inflammatory cytokines in Alzheimer's disease rats.

As a part of Alzheimer's disease (AD) development the mammalian target of rapamycin (mTOR) has been reported to play a crucial role in regulating cognition and can be used as a neuronal marker. Neuro-inflammation is also a cause of the pathophysiological process in AD. Thus, we examined the protein expression levels of mTOR and its downstream pathways as well as pro-inflammatory cytokines (PICs) in the brain of AD rats.

The role of the QseC quorum-sensing sensor kinase in epinephrine-enhanced motility and biofilm formation by Escherichia coli.

Biofilms play a pivotal role in infections related to devices. Biofilm formation in Escherichia coli is mediated by the quorum-sensing E. coli regulator C (QseC), the histidine sensor kinase that can sense epinephrine (EPI)/norepinephrine (NE).

[Significance of high sensitivity C-reactive protein level for predicting risk of nonalcoholic fatty liver in type 2 diabetes mellitus patients].

Objective: To investigate the significance of high sensitivity C-reactive protein (hsCRP) levels in serum for detecting type 2 diabetes mellitus (T2DM) patients at risk of developing nonalcoholic fatty liver (NAFLD).

Methods: Individuals with T2DM (n = 9489) were recruited from the Kailuan Company between 2006 and 2007 for the first phase of this community-based prospective cohort study. For the second phase of the study, the original cohort was recruited for follow-up (at two years from each subject's original enrollment date (baseline)).

[Relationship between high incidence of lung cancer among non-smoking women and silica in C1 bituminous coal in Xuanwei, Yunnan Province, China].

Objective: To measure the content of silica in C1 bituminous coal and its combustion products in the high-incidence area of lung cancer in Xuanwei, Yunnan Province, China and to investigate the relationship between high incidence of lung cancer among non-smoking women and silica produced naturally in C1 bituminous coal in Xuan Wei.

Methods: The C1 bituminous coal widely used in the high-incidence area of lung cancer in Xuanwei was selected as experiment group, while the C2+1, K7, and M30 bituminous coal that was mined and used in the low-incidence area of lung cancer in Xuanwei for more than 10 years were selected as control group. Fourteen paraffin-embedded cancer tissue samples from the non-smoking women with non-small cell lung cancer who were born in Xuanwei and were at least the 3rd generation of the family living there were collected from the department of pathology, the third affiliated hospital of kunming medical university (tumor hospital of yunnan province).

Spontaneous vertebral artery dissection: report of 16 cases.

Unlabelled: background and objectives: Spontaneous vertebral artery dissection (sVAD) is a rare condition and can potentially cause a stroke, particularly in young to middle-aged people.

Patients And Methods: The clinical manifestations, medical imaging characteristics, treatment, and prognosis of 16 patients with sVAD were analyzed.

Results: None of the 16 patients had a history of head or neck trauma.
