Photoactivated 9-methylacridine destroys midgut tissues of Aedes aegypti larvae by targeting ROS-mediated apoptosis in the mitochondrial pathway of midgut cells.

An aromatic ring-containing compound with a wide range of biological activities, 9-methylacridine (AD-9-Me) is a precursor for the synthesis of various drugs. However, its photoactivation properties and mechanism of damage as a photo activator against Aedes aegypti are unknown. The toxic effects of AD-9-Me on Aedes aegypti mosquitoes were determined under light and non-light conditions.

Cell death induced by α-terthienyl via reactive oxygen species-mediated mitochondrial dysfunction and oxidative stress in the midgut of Aedes aegypti larvae.

α-Terthienyl (α-T) is a photosensitizer that produces many reactive oxygen species (ROS) under ultraviolet light. Here, we aimed to evaluate the oxidation mechanism of the 25%, 50%, and 75% lethal concentrations in Aedes aegypti larvae; the lethal concentration of α-T was used as the test value. The effects on mitochondria, oxidative stress, and cell death patterns caused by ROS were evaluated.

To explore the mechanisms, proteins potentially related to the fruiting body formation, proteins from fruiting bodies, and mycelia of  species were assessed by using two-dimensional fluorescence difference gel electrophoresis, and the differential expression proteins were identified by matrix-assisted laser desorption/ionisation tandem time of flight mass spectrometry. The results showed that 198 differential expression proteins (252 protein spots) were identified during the fruiting body formation of  species, and 24 of them involved in fruiting body development in both  and other microorganisms.

Microwave-Assisted Extraction, Chemical Structures, and Chain Conformation of Polysaccharides from a Novel Cordyceps Sinensis Fungus UM01.

Cordyceps sinensis is a well-known tonic food with broad medicinal properties. The aim of the present study was to investigate the optimization of microwave-assisted extraction (MAE) and characterize chemical structures and chain conformation of polysaccharides from a novel C. sinensis fungus UM01.

Fermentation optimization for the production of bioactive polysaccharides from Cordyceps sinensis fungus UM01.

The optimal fermentation conditions and medium for the production of bioactive polysaccharides from the mycelium of Cordyceps sinensis fungus UM01 were investigated by using orthogonal design and high performance size exclusion chromatography coupled with multi-angel laser light scattering and refractive index detector (HPSEC-MALLS-RID). Results showed that the optimal temperature, initial pH, rotation speed, medium capacity (ratio of medium volume to the volume of flask bottle) and inoculums volume for the mycelium growth were 15 °C, pH 6.0, 150 rpm, 2/5 (v/v), and 3% (v/v), respectively.

Chain conformation and immunomodulatory activity of a hyperbranched polysaccharide from Cordyceps sinensis.

A polysaccharide, named as cordysinan, extracted from natural Cordyceps sinensis, was identified as a hyperbranched heteropolysaccharide from the results of FT-IR, GC-MS, and carbohydrate analysis by carbohydrate gel electrophoresis analysis, as well as the degree of branching of cordysinan was 43.3%.

Isolate of fungi strains from natural Cordyceps sinensis to achieve a large-scale production by fermentation is an alternative choice.

Possible novel roles of poly(rC)-binding protein 1 in SH-SY5Y neurocytes: an analysis using a dynamic Bayesian network.

Objective: Poly(rC)-binding protein 1 (PCBP1) belongs to the heterogeneous nuclear ribonucleoprotein family and participates in transcriptional and translational regulation. Previous work has identified transcripts targeted by both knockdown and overexpression of PCBP1 in SH-SY5Y neuroblastoma cells using a microarray or ProteomeLab protein fractionation 2-dimensions (PF-2D) and quadrupole time-of-flight mass spectrometer. The present study aimed to further determine whether these altered transcripts from major pathways (such as Wnt signaling, TGF-β signaling, cell cycling, and apoptosis) and two other genes, H2AFX and H2BFS (screened by PF-2D), have spatial relationships.

Phenotypic differentiation is associated with gender plasticity and its responsive delay to environmental changes in Alternanthera philoxeroides--phenotypic differentiation in alligator weed.

Phenotypic plasticity is common in many taxa, and it may increase an organism's fitness in heterogeneous environments. However, in some cases, the frequency of environmental changes can be faster than the ability of the individual to produce new adaptive phenotypes. The importance of such a time delay in terms of individual fitness and species adaptability has not been well studied.

Zinc finger protein A20 promotes regeneration of small-for-size liver allograft and suppresses rejection and results in a longer survival in recipient rats.

[Studies on photosensitive dyes binding to monocrystalline germanium surface].

In this paper, two simple cyanine dyes were synthesized through allyl alcohol monomer, and were bound to the polished monocrystalline germanium surface using a new chemical method. Raman spectra and X-ray photoelectron spectra (XPS) were used to analyze the dye-binding germanium wafers. In comparison with the contrast germanium wafer, the dye-binding germanium wafers showed that the intensity of the first grade Raman peak of the germanium substrate was reduced and some new Raman peaks corresponding to the dyes appeared from 600 to 3,200 cm-1.
