Midbrain dopamine oxidation links ubiquitination of glutathione peroxidase 4 to ferroptosis of dopaminergic neurons.

Parkinson's disease (PD) is a neurodegenerative disorder characterized by the gradual loss of midbrain dopaminergic neurons in association with aggregation of α-synuclein. Oxidative damage has been widely implicated in this disease, though the mechanisms involved remain elusive. Here, we demonstrated that preferential accumulation of peroxidized phospholipids and loss of the antioxidant enzyme glutathione peroxidase 4 (GPX4) were responsible for vulnerability of midbrain dopaminergic neurons and progressive motor dysfunctions in a mouse model of PD.

[Correlation between expression of forkhead box M1 (FOXM1) and clinicopathological features and prognosis in patients with non-small cell lung cancer (NSCLC)].

Objective: To investigate the expression of forkhead box M1 (FOXM1) and its correlation with clinicopathological features and prognosis in patients with non-small cell lung cancer (NSCLC).

Methods: The expression of FOXM1 in 68 cases of NSCLC was detected by immunohistochemistry. The FOXM1 expression in 6 tumor tissues (3 cases with negative and 3 cases with positive expression of FOXM1) was analyzed by Western blotting to confirm the immunohistochemical results.

Identification of plasma microRNA-21 as a biomarker for early detection and chemosensitivity of non-small cell lung cancer.

Studies have shown cell-free microRNA (miRNA) circulating in the serum and plasma with specific expression in cancer, indicating the potential of using miRNAs as biomarkers for cancer diagnosis and therapy. This study was to investigate whether plasma miRNA-21 (miR-21) can be used as a biomarker for the early detection of non-small cell lung cancer (NSCLC) and to explore its association with clinicopathologic features and sensitivity to platinum-based chemotherapy. We used real-time RT-PCR to investigate the expression of miR-21 in the plasma of 63 NSCLC patients and 30 healthy controls and correlated the findings with early diagnosis, pathologic parameters, and treatment.

Reduction of Plasma MicroRNA-21 is Associated with Chemotherapeutic Response in Patients with Non-small Cell Lung Cancer.

Objective: To examine plasma microRNA-21 (miR-21) level in patients with non-small cell lung cancer (NSCLC) and its potential correlation with chemotherapeutic response.

Methods: 77 NSCLC patients and 36 age and sex-matched healthy controls were included. Plasma miR-21 concentration was examined using a quantitative real-time reverse transcription polymerase chain reaction assay (qRT-PCR).

PTA wastewater molecular toxicity detected with gene chip.

The purified terephthalic acid (PTA) petrochemical wastewater molecular toxicity detected by use of Mouse Genome 430A 2.0 GeneChip was conducted in this research. The toxic dose to male mice was 0.

Purified terephthalic acid wastewater biodegradation and toxicity.

The biodegradation and toxicity of the purified terephthalic acid (PTA) processing wastewater was researched at NJYZ pilot with the fusant strain Fhhh in the carrier activated sludge process (CASP). Sludge loading rate (SLR) for Fhhh to COD of the wastewater was 1.09 d(-1) and to PTA in the wastewater was 0.

Pilot regulation of MnP-SA for treating PTA wastewater.

In the pilot study of treating the purified terephthalic acid (PTA) wastewater with the functional Strain Fhhh in the carrier activated sludge process (CASP), the ratio of COD: TN: TP and the concentrations of Cu, Mn, Se and Zn were controlled to improve the manganese peroxidase (MnP) levels for increasing the treatment efficiency. When the ratio of COD: TN: TP was 100: 0.36: 0.

[Effectiveness for medicine wastewater treatment biotechnology].

The effectiveness for the XZEH medicine wastewater treatment biotechnology was conducted. The results show that it needs to increase 28% of the aeration tank volume in order to meet the effluent COD concentration at the first grade wastewater discharge standard level in China. If the engineered strain Xhhh and informatics software (Ebis) were used, the specific degradation rate of Xhhh strain may be higher 128% than that of the natural bacterium XZ strain and the aeration tank needed may be 51% decreased.
