Design of C-symmetric tridentate ligands for enantioselective dearomative [3 + 2] annulation of indoles with aminocyclopropanes.

Chiral polycyclic indolines are widely present in natural products and have become the focus of extensive synthetic efforts. Here, we show the catalytic asymmetric dearomative [3 + 2] annulation of indoles with donor-acceptor aminocyclopropanes to construct tricyclic indolines. Key to the success of the reaction is the rational design of C-symmetric bifunctional tridentate imidazoline-pyrroloimidazolone pyridine ligand.

Parental Stress as the Mediator Between Symptom Burden and the Quality of Life of Chinese Children With Cancer.

Background: Because of their cancer and treatment adverse effects, most pediatric oncology patients will experience 1 or more symptoms at one time that can seriously affect their quality of life. Because these children are attached to parents, their symptom burden directly influences the parental stress level and parental interpretations of their children's quality of life.

Objective: The aim of this study was to examine the association between child-reported symptom burden and the pediatric quality of life reported by children with cancer and their parents, and whether parental perceived stress mediates these relationships.

Gastrodia elata blume ameliorates circadian rhythm disorder-induced mice memory impairment.

Circadian rhythm disorder (CRD) in space flight can lead to memory impairment, performance decrements and adverse health outcomes, the main manifestations of which are circadian desynchronization, sleep loss and insomnia.

Proteomic Analysis Reveals That Placenta-Specific Protein 9 Inhibits Proliferation and Stimulates Motility of Human Bronchial Epithelial Cells.

Placenta-specific protein 9 (PLAC9) is a putative secretory protein that was initially identified in the placenta and is involved in cell proliferation and motility. Bioinformatics analyses revealed that PLAC9 is repressed in lung cancers (LCs), especially lung adenocarcinomas, compared to that in the paired adjacent normal tissues, indicating that PLAC9 might be involved in the pathogenesis of pulmonary diseases. To investigate the potential role of PLAC9 in the abnormal reprogramming of airway epithelial cells (AECs), a key cause of pulmonary diseases, we constructed a stable PLAC9-overexpressing human bronchial epithelial cell line (16HBE-GFP-).
