Parkinson's disease (PD) is the most common neurodegenerative movement disease. It is featured by abnormal alpha-synuclein (-syn) aggregation in dopaminergic neurons in the substantia nigra. Macroautophagy (autophagy) is an evolutionarily conserved cellular process for degradation of cellular contents, including protein aggregates, to maintain cellular homeostasis.
View Article and Find Full Text PDFA reduced removal of dysfunctional mitochondria is common to aging and age-related neurodegenerative pathologies such as Alzheimer's disease (AD). Strategies for treating such impaired mitophagy would benefit from the identification of mitophagy modulators. Here we report the combined use of unsupervised machine learning (involving vector representations of molecular structures, pharmacophore fingerprinting and conformer fingerprinting) and a cross-species approach for the screening and experimental validation of new mitophagy-inducing compounds.

Methods: A multicentre, randomized, double-blinded, parallel, placebo-controlled, clinical trial was performed in 576 patients (432 patients in the TNG group, 144 patients in the PC group), and 1 in the experimental group withdrew due to nonuse of drug. Patients were randomized to receive TNG or PC applied to knee skin at 3g per time, 2 times per day, which lasted for 3 weeks.
We report, from a theoretical point of view, the first comparative study between the highly water-stable hydroxamate and the widely used carboxylate, in addition to the robust phosphate anchors. Theoretical calculations reveal that hydroxamate would be better for photoabsorption. A quantum dynamics description of the interfacial electron transfer (IET), including the underlying nuclear motion effect, is presented.

According to our results, all of the lowest-lying and strongest absorption peaks can be assigned as having a mixed ligand-to-ligand/metal-to-ligand charge transfer (LLCT/MLCT) character, but the different ways of introducing phenyl have a great effect on the absorption wavelength variation. In addition, the charge transfer characteristics of lowest-lying emission have some minute differences.

Purpose: This meta-analysis was aimed to evaluate the association of glutathione S-transferase P1 (GSTP1) Ile105Val genetic polymorphism with susceptibility to oral cancer.
Methods: A literature search of PubMed, Chinese BioMedical, Wanfang, VIP, CNKI databases was conducted from inception to July 15th, 2013. Crude odd ration (OR) with 95% confidence intervals (CI) was calculated.

Background: MicroRNA-200a (miR-200a) has been reported to regulate tumour progression in several tumours but little is known about its role in neuroblastoma. Our aim was to investigate the potential role and mechanism of miR-200a in neuroblastomas.
Materials And Methods: Expression levels of miR-200a in tissues were determined using RT-PCR.

Objective: To explore the molecular mechanism of miR-124 suppressing the proliferation and invasion of gastric cancer cells.
Methods: SPHK1 3'UTR-luciferase vector was constructed and luciferase reporter gene assay was employed to examine the effect of miR-124 on luciferase activity. Human gastric cancer MGC-803 cells were transfected with miR-124 mimics, and then Western blot was performed to detect the expression of SPHK1 protein.
Naringin, a well-known flavanone glycoside of grapefruit and citrus fruits, was found to be as an effective anti-inflammatory compound in our previous lipopolysaccharide-induced acute lung injury mouse model via blockading activity of nuclear factor κB. The current study sought to explore the anti-inflammatory effects of naringin on chronic pulmonary neutrophilic inflammation in cigarette smoke (CS)-induced rats. Seventy Sprague-Dawley rats were randomly divided into seven groups to study the effects of CS with or without various concentrations of naringin or saline for 8 weeks.
View Article and Find Full Text PDFNaringenin, the aglycone of naringin, has been reported to attenuate MUC5AC secretion by inhibiting activity of nuclear factor kappa B (NF-κB) via EGFR-PI3K-Akt/ERK MAPKinase signaling pathways. However, previous studies demonstrated that the MUC5AC promoter was located in two different regions: an activator protein-1 (AP-1) binding site and a NF-κB binding site. The current study comprehensively determined the involvement of MAPKs/AP-1 and IKKs/IκB/NF-κB in epidermal growth factor (EGF)-induced A549 cells, and sought to ascertain the signaling pathways of naringin imparted in suppression of EGF-induced MUC5AC secretion.

Methods: Between March 2004 and April 2009, 23 patients with ipsilateral intertrochanteric and femoral shaft fractures were treated with PFNA-long or plate combinations. The patients were divided into two groups.
