Background and aims: Dexamethasone is a common glucocorticoid medication with adverse effects that can cause muscle atrophy， but no drug intervention has been approved or recommended for this condition. KF-8 is a rice bran-derived anti-oxidant peptide that extends the life span of Caenorhabditis elegans. Methods: We established a C. elegans model of dexamethasone-induced myopathy to evaluate the potential therapeutic effects of KF-8 in this model. C. elegans muscle function was assessed in terms of locomotory behaviors including crawling， swimming， burrowing， pharyngeal pumping， and head swing. Muscle actin filament integrity was evaluated using fluorescence imaging. The molecular mechanisms of KF-8 were investigated using transcriptome sequencing， qRT-PCR， RNA interference， and western blot analysis. Results: Dexamethasone disrupted actin filaments in the striated muscles of the body wall and inhibited C. elegans crawling， swimming， burrowing， pharyngeal pumping， and head swing. KF-8 reversed the actin filament disruption and locomotor dysfunction induced by dexamethasone. Transcriptome sequencing， pathway enrichment， and qRT-PCR analyses revealed that KF-8 regulated the locomotion-related genes W04G5.10， vha-12， and ddr-1， as well as age-1 (the catalytic subunit ortholog of PI3K)， and akt1. RNA interference， conducted using a genetically engineered E. coli HT115 strain as a food source， confirmed age-1 as a key regulator of locomotor function of C. elegans. Further mechanistic studies with C2C12 myotubes showed that KF-8 regulated the IRS-PI3K-Akt pathway， the master regulator of protein synthesis and degradation. Conclusion: Together， these findings suggest that KF-8 protects against dexamethasone-induced myopathy in C. elegans by regulating locomotion-related genes and the IRS-PI3K-Akt pathway.

Tetrahydro-γ-carbolines(THγ Cs) constitute one of the most important subtypes of indole alkaloids. In addition to being substructures of natural products, these structural motifs and moieties can often be found in pharmaceuticals due to their diverse bioactivities such as antiviral, antibacterial, antifungal,antiparasitic, antitumor, anti-inflammatory, and neuropharmacological activities. Beyond the pharmacological and biological aspects of these scaffolds, they have considerable synthetic applications for the construction of further bioactive compounds, too. The aim of this review is to summarize recent developments in the synthesis of this compound class.

Acquisition of plant phenotypic information facilitates plant breeding, sheds light on gene action, and can be applied to optimize the quality of agricultural and forestry products. Because leaves often show the fastest responses to external environmental stimuli, leaf phenotypic traits are indicators of plant growth,health, and stress levels. Combination of new imaging sensors, image processing, and data analytics permits measurement over the full life span of plants at high temporal resolution and at several organizational levels from organs to individual plants to field populations of plants. We review the optical sensors and associated data analytics used for measuring morphological, physiological, and biochemical traits of plant leaves on multiple scales. We summarize the characteristics, advantages and limitations of optical sensing and data-processing methods applied in various plant phenotyping scenarios. Finally, we discuss the future prospects of plant leaf phenotyping research. This review aims to help researchers choose appropriate optical sensors and data processing methods to acquire plant leaf phenotypes rapidly,accurately, and cost-effectively.

Effect of Extractive-Dissolving Treatment on the Characteristics of Laminated Wood Assembled from Oily Keruing Wood

引用

Journal of Agricultural Science and Technology(B) 2011年第8期1卷 1191-1196页

作者： J. Malik and A. Santoso research and development center for forestry enginering and forest products processing Jl. Gunung Batu 5 Bogor 16000Indonesia

Utilization of oily keruing wood for laminated wood product has not been optimal yet because of the appearance of extractive substance as oil on wood surface and hence disturbing the bonding process. A study has been conducted by manufacturing laminated wood from oily keruing wood (Dipterocarpus hasseltii) after extracting its oil by boiling the wood in the mixture of water and ethanol solution in several proportions. The assessment on the treated wood and the resulting laminated wood covered some characteristics i. e., wettability, static bending, bonding strength, and delamination. The results show that boiling treatment in ethanol-water solution can improve wetting properties significantly. The extractive does not affect mechanical characteristics of the laminated wood. Increasing of water proportion in ethanol-water solution causes the decreasing of the bonding strength and increasing delamination value of the laminated wood. The result also shows that oily keruing wood after the treatment can be used as material for laminated wood.
