Oral intake of hydrogen-rich water ameliorated chlorpyrifos-induced neurotoxicity in rats.

Chronic exposure to low-levels of organophosphate (OP) compounds, such as chlorpyrifos (CPF), induces oxidative stress and could be related to neurological disorders. Hydrogen has been identified as a novel antioxidant which could selectively scavenge hydroxyl radicals. We explore whether intake of hydrogen-rich water (HRW) can protect Wistar rats from CPF-induced neurotoxicity.

Comparison of the effects of symmetric and asymmetric temperature elevation and CO2 enrichment on yield and evapotranspiration of winter wheat (Triticum aestivum L.).

Under the changing climate, asymmetric warming pattern would be more likely during day and night time, instead of symmetric one. Concurrently, the growth responses and water use of plants may be different compared with those estimated based on symmetric warming. In this work, it was compared with the effects of symmetric (ETs) and asymmetric (ETa) elevation of temperature alone, and in interaction with elevated carbon dioxide concentration (EC), on the grain yield (GY) and evapotranspiration in winter wheat (Triticum aestivum L.

Feasibility analysis of the value of Q method in the classification and understanding of expert experience.

The Q method, combining qualitative and quantitative methods, refers to the qualitative analysis of Q-sorts based on quantitative techniques. It is used to research individual subjective experience, analyzing consensus and divergence to identify and categorize subjects' viewpoints. The sorting process is completely performed by the subjects, independent of study researchers.

Immune reconstitution of acquired immune deficiency syndrome.

Acquired immune deficiency syndrome (AIDS) is a chronic infectious disease, which the patients are infected with human immunodeficiency virus (HIV). HIV damages the human's immune function and causes CD4 cell decline in the number and function. Immune reconstitution is an important treatment to AIDS.

[Preliminary research on application of Q method in studying experiences of Chinese medicine famous veteran doctors].

As the stands, one-sidedness of subjective understanding and subjective bias is surely existed in the study of Chinese medicine (CM) doctors' experiences, so to find appropriate methods for inheriting the real experiences of experts is needed. Since CM thinking presents as a system integral way of intention thinking and a mental process of subject, to study CM experts' experiences in virtue of Q method, a psychological research method for the subjective sense, must be feasible. The application of Q method was inspected in this article, it was considered to be capable of sorting the experts, integrating the opinions of experts and comparing their opinions from multi-pointviews.

Aim: To investigate the tropism of bone marrow mesenchymal stem cells (BMSCs) in neurogenic differentiation for glioma and SDF-1alpha.

Methods: BHA, bFGF, and DMSO were used to induce the neural differentiation of BMSCs, and the expression of neural markers, Nestin, beta-III-Tubulin and NSE were analyzed by immunocytochemistry. We investigated, by using the Dunn chamber, the migration of BMSCs in neurogenic differentiation towards glioma and SDF-1alpha.

Investigation on the relationship between leaf water use efficiency and physio-biochemical traits of winter wheat under rained condition.

Different statistical methods and path analysis were used to study the relationship between leaf water use efficiency (WUE) and physio-biochemical traits for 19 wheat genotypes, including photosynthesis rate (P(n)), stomatal conductance (g(s)), transpiration rate (T(r)), intercellular concentration of carbon oxide (C(i)), leaf water potential (Psi(w)), leaf temperature, wax content, leaf relative water content (RWC), rate of water loss from excised-leaf (RWL), peroxidase (POD) and superoxide dismutase (SOD) activities. The results showed that photosynthesis rate, stomatal conductance and transpiration rate were the most important leaf WUE variables under rained conditions. Based on the results of five statistical analyses, it is reasonable to assume that high leaf WUE wheat under the rained could be obtained by selecting breeding materials with high photosynthesis rate, low transpiration rate and stomatal conductance.

Salt modulates gravity signaling pathway to regulate growth direction of primary roots in Arabidopsis.

Plant root architecture is highly plastic during development and can adapt to many environmental stresses. The proper distribution of roots within the soil under various conditions such as salinity, water deficit, and nutrient deficiency greatly affects plant survival. Salinity profoundly affects the root system architecture of Arabidopsis (Arabidopsis thaliana).

Arabidopsis EIN2 modulates stress response through abscisic acid response pathway.

The nuclear protein ETHYLENE INSENSITIVE2 (EIN2) is a central component of the ethylene signal transduction pathway in plants, and plays an important role in mediating cross-links between several hormone response pathways, including abscisic acid (ABA). ABA mediates stress responses in plants, but there is no report on the role of EIN2 on plant response to salt and osmotic stresses. Here, we show that EIN2 gene regulates plant response to osmotic and salt stress through an ABA-dependent pathway in Arabidopsis.
