Azonaphthalenes have been verified as a class of effective arylation reagents in a variety of asymmetric transformations. Here a highly efficient approach to construct triaryl-substituted all-carbon quaternary stereocenters through chiral phosphoric acid-catalyzed enantioselective arylation of 3-aryl-2-oxindoles with azonaphthalenes is disclosed. This chemistry is scalable and displays excellent functional group tolerance, furnishing a series of 3,3-disubstituted 2-oxindole derivatives in good yields with excellent enantiocontrol.

In this study, we aim to explore the interaction network of intestinal flora and cell inflammation in T2DM.
Methods: This a case-control study.
Background: Acute myocardial injury (AMI), which is induced by renal ischemia-reperfusion (IR), is a significant cause of acute kidney injury (AKI)-related associated death. Obesity increases the severity and frequency of AMI and AKI. Tanshinone IIA (TIIA) combined with cyclosporine A (CsA) pretreatment was used to alleviate myocardial cell apoptosis induced by renal IR, and to determine whether TIIA combined with CsA would attenuate myocardial cell apoptosis by modulating mitochondrial function through the PI3K/Akt/Bad pathway in obese rats.

Methods: T2DM patients and normal controls were recruited. Fasting plasma and fecal samples were collected from the subjects, and their biochemical indexes including fasting blood glucose (FBG), glycated hemoglobin (HbAlc), cholesterol (TC), total triglycerides (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and insulin were recorded.
Purpose: The aim of this study was to investigate the molecular mechanism of lung cancer among nonsmoking Taiwan females.
Materials And Methods: By using the GSE19804 microarray data accessible from Gene Expression Omnibus (GEO) database, we identified differentially expressed genes (DEGs) between nonsmoking female lung cancer patients and healthy controls (!logFC! >1.5 and p-value < 0.
Background: Single nucleotide polymorphism (SNP) in DNA repair genes can be used to explain the differences in survival of platinum-treated non-small cell lung cancer (NSCLC) patients regardless of their performance status. To define the role of DNA repair gene SNPs in NSCLC patients, we investigated the association between survival and 12 different SNPs of 9 DNA repair genes.
Methods: 340 patients were treated with platinum-based chemotherapy.
Background: DNA excision repair gene expression plays a pivotal role in the resistance of platinum-based doublet chemotherapy of nonsmall cell lung cancer (NSCLC) in clinical practice. The aim of this study was to investigate the relationship of the excision repair cross-complementation group 1 (ERCC1) mRNA level in fresh tumor tissue and the efficacy of platinum-based chemotherapy of NSCLC.
Patients And Methods: 100 patients diagnosed with NSCLC, including stage IIIB with malignant pleural effusion, stage IV, and recurrent disease, were enrolled in this study.
This study was to investigate whether the expressions of DNA repair genes ERCC1 (excision repair cross complementing 1), RRM1 (ribonucleotide reductase subunit M1) and BRCA1 (breast cancer 1) affected clinical outcome in patients with NSCLC. Patients with stage IIIb/IV NSCLC were given platinum-based chemotherapy. Messenger RNA expression levels of ERCC1, BRCA1 and RRM1 were determined by real-time polymerase chain reaction with TaqMan probes in the tumor.
