We previously found that extract from an edible and medicinal plant Chrysanthemum indicum L.

Divergent syntheses of okaramines C, J, L, and S-U.

The total synthesis of six novel okaramines (C, J, L, and S-U) was accomplished with a precise synthesis scheme involving a few steps and a practical yield of 6.7%-23% was obtained. The significance of this study includes the design of a successful and convenient synthesis method for preparation of 3a-hydroxy-pyrrolo[2,3-b]-indole and C-7 prenylated l-tryptophan derivatives using a nucleophilic attack of cyclopropylazetoindoline and an aza-Claisen rearrangement of N-reverse-prenyl tryptophan, respectively.

Blood and Cerebrospinal Fluid Autoantibody to Aβ Levels in Patients with Alzheimer's Disease: a Meta-Analysis Study.

Autoantibodies to beta amyloid (Aβ) have been suggested to be involved in the pathogenesis of Alzheimer's disease (AD). However, data from clinical studies were inconsistent on autoantibody to Aβ levels in patients with AD. Therefore, we systematically searched the literature and performed meta-analysis to summarize the data of autoantibodies to Aβ in AD patients.

The Effect of Estrogen Replacement Therapy on Alzheimer's Disease and Parkinson's Disease in Postmenopausal Women: A Meta-Analysis.

Estrogen replacement therapy (ERT) is a common treatment method for menopausal syndrome; however, its therapeutic value for the treatment of neurological diseases is still unclear. Epidemiological studies were performed, and the effect of postmenopausal ERT on treating neurodegenerative diseases, including Alzheimer's disease (AD) and Parkinson's disease (PD), was summarized through a meta-analysis. Twenty-one articles were selected using a systematic searching of the contents listed on PubMed and Web of Science before June 1, 2019.

Mallotus oblongifolius extracts ameliorate ischemic nerve damage by increasing endogenous neural stem cell proliferation through the Wnt/β-catenin signaling pathway.

Mallotus oblongifolius (MO), an edible medicinal plant from Hainan in China, shows a wide range of bioactivities. The daily consumption of MO or its extracts has been observed to ameliorate ischemic nerve injury. However the mechanisms remain unclear.

Neuro-Protective Role of Metformin in Patients with Acute Stroke and Type 2 Diabetes Mellitus via AMPK/Mammalian Target of Rapamycin (mTOR) Signaling Pathway and Oxidative Stress.

BACKGROUND We investigated the effects of metformin on neurological function and oxidative stress in patients with type 2 diabetes mellitus with acute stroke. MATERIAL AND METHODS We randomly assigned 80 acute stroke patients to 2 groups: the metformin combined group and the insulin group. Each group had 40 patients and all were treated with standard stroke treatment.

Genome-Wide, Integrative Analysis Implicates Exosome-Derived MicroRNA Dysregulation in Schizophrenia.

Genetic variants conferring risk for schizophrenia (SCZ) have been extensively studied, but the role of posttranscriptional mechanisms in SCZ is not well studied. Here we performed the first genome-wide microRNA (miRNA) expression profiling in serum-derived exosome from 49 first-episode, drug-free SCZ patients and 46 controls and identified miRNAs and co-regulated modules that were perturbed in SCZ. Putative targets of these SCZ-affected miRNAs were enriched strongly for genes that have been implicated in protein glycosylation and were also related to neurotransmitter receptor and dendrite (spine) development.

Effects of soil improvement technology on soil quality in solar greenhouse.

Currently, cucumber cultivation is mainly through monoculture, as continuous culture leads to the decrease of crop yield and soil quality. In order to improve soil quality to achieve continuous monocultures, soil physicochemical properties, microbial biomass, content of phenolic compounds, and the size of bacterial, fungal, ammonia-oxidizing bacteria (AOB), and Fusarium oxysporum were first evaluated in cucumber monoculture solar greenhouse. Soil improvement technology, including catch wheat (CW), calcium cyanamide disinfection (LN), and straw reactor technology (SR) during summer fallow period, was compared with conventional fallow (CK).

Concise Synthesis of Natural Phenylphenalenone Phytoalexins and a Regioisomer.
