Preclinical evidence and possible mechanisms of β-asarone for rats and mice with Alzheimer's disease: A systematic review and meta-analysis.

Currently, there are many different drugs to improve Alzheimer's disease (AD) from different pathways. As a supplement and alternative medicine, traditional Chinese medicine (TCM) targets multiple pathways which may be different from classical Western medicine, which may be orchestrated with Western medicine to materialize multiplying efficacy in AD patients. To investigate the therapeutic effect and assess the available preclinical evidence and possible mechanisms of β-asarone which was extracted from Acorus gramineus Soland (Araceae, AGS) for AD based on rat and mouse animal models.

Pre-service teachers' perceptions of technological pedagogical content knowledge in mainland China: A survey of teachers of Chinese as a second language.

There is an urgent need to address the critical demand for qualified Chinese language teachers against the background of China's seeking greater Sino-foreign cultural and educational cooperation. The literature on integrating technological pedagogical content knowledge (TPACK) in language teaching has been increasing in the last few years. However, most of these studies focus on English language teachers.

A proteomic-based investigation of potential copper-responsive biomarkers: Proteins, conceptual networks, and metabolic pathways featuring Penicillium janthinellum from a heavy metal-polluted ecological niche.

Filamentous fungi-copper (Cu) interactions are very important in the formation of natural ecosystems and the bioremediation of heavy metal pollution. However, important issues at the proteome level remain unclear. We compared six proteomes from Cu-resistant wild-type (WT) Penicillium janthinellum strain GXCR and a Cu-sensitive mutant (EC-6) under 0, 0.

Therapeutic effect of okra extract on gestational diabetes mellitus rats induced by streptozotocin.

Objective: To explore the effect of okra extract on gestational diabetes mellitus (GDM) rats and its probable molecular mechanism.

Methods: A total of 30 female SD rats were caged with male rats for pregnancy, 27 pregnant rats were obtained and weighed. The pregnant rats were equally randomized into the control group, GDM group and intervention group.

Paths and determinants for Penicillium janthinellum to resist low and high copper.

Copper (Cu) tolerance was well understood in fungi yeasts but not in filamentous fungi. Filamentous fungi are eukaryotes but unlike eukaryotic fungi yeasts, which are a collection of various fungi that are maybe classified into different taxa but all characterized by growth as filamentous hyphae cells and with a complex morphology. The current knowledge of Cu resistance of filamentous fungi is still fragmental and therefore needs to be bridged.

[The correlation between the level of serum VEGF and bFGF with metastasis and prognosis of osteosarcoma].

Aim: To investigate the correlation between the level of serum VEGF and bFGF with metastasis and re- currence of osteosarcoma.

Methods: 52 patients with osteosarcoma and 60 healthy people as control group were selected. The serum contents of VEGF and bFGF were determined with ELISA before and after operation.

[Quantum chemistry study on fluorescence spectra of six coumarin dyes].

A theoretical study on fluorescence spectra of six coumarin dyes is given in the present paper. Their geometric configurations were optimized by semi-empirical method AM1. For all optimal configurations, there is no imaginary frequency in vibrational analysis.

[Quantum chemistry study on fluorescence spectra of three aromatic hydrocarbons].

In the present paper, the fluorescence spectra of three common pesticides, isoprocarb, metolcarb and pirimicarb, were theoretically studied. The geometries of these compounds were fully optimized by density function theory (DFT) method at the B3LYP/6-31+G level. The three compounds under study were confirmed as true minima on the potential energy surface in the presence of only real frequencies by the vibrational analysis.

[Efficacy and prognosis analysis in 188 children with acute lymphoblastic leukemia of China].

Objective: To analyze the therapeutic effect and the influencing factors of event-free survival (EFS) of childhood acute lymphoblastic leukemia (ALL) in Xiangya Hospital of Central South University and the First Affiliated Hospital of Guangxi Medical University.

Methods: All the patients adopted chemotherapy according to therapeutic guideline revised by the Subspecialty Group of Hematology, The Society of Pediatrics, Chinese Medical Association for the second-time in 1998 (the Rongcheng ALL-98 Protocol). Kaplan-Meier method was used to estimate the survival rates of 188 patients who received therapy with good compliance.
