Modulation of the driving forces for adsorption on MIL-101 analogues by decoration with sulfonic acid functional groups: superior selective adsorption of hazardous anionic dyes.

Toxic dyes pose a dramatic threat to human health and the environment when they are directly released into the water environment. Therefore, new porous materials with excellent adsorption performances are urgently needed to remove toxic dyes from wastewater. Herein, we report a sulfo-modified metal-organic framework (MIL-101-SOH), which exhibits superior adsorption performance toward toxic dyes.

The endoparasitoid Psyllaephagus arenarius benefits from ectoparasitic venom via multiparasitism with the ectoparasitoid Tamarixia lyciumi.

As solitary nymphal parasitoids of Paratrioza sinica, the ectoparasitoid Tamarixia lyciumi and the endoparasitoid Psyllaephagus arenarius act as effective biocontrol agents. Thus, it is necessary to facilitate mass productions of both species. Despite showing an excellent parasitic ability, Ps.

Rigid Coplanar Polymers for Stable n-Type Polymer Thermoelectrics.

Low n-doping efficiency and inferior stability restrict the thermoelectric performance of n-type conjugated polymers, making their performance lag far behind of their p-type counterparts. Reported here are two rigid coplanar poly(p-phenylene vinylene) (PPV) derivatives, LPPV-1 and LPPV-2, which show nearly torsion-free backbones. The fused electron-deficient rigid structures endow the derivatives with less conformational disorder and low-lying lowest unoccupied molecular orbital (LUMO) levels, down to -4.

Effect of surface charge status of amorphous porous coordination polymer particles on the adsorption of organic dyes from an aqueous solution.

The surface charge status of coordination polymer particles (CPPs) from negative electrification through electrically neutral to positive electrification was achieved by varying the amount of acetic acid. The adsorption capacity of CPPs-1 with a negatively charged framework for the anionic dye Congo red (CR) is much higher than that of the CPPs-5, which possess a positively charged framework, because of different adsorption mechanisms. This is the first reported example of negatively charged CPPs exhibiting excellent adsorption performance toward anionic organic dyes.

Predicting new indications of compounds with a network pharmacology approach: Liuwei Dihuang Wan as a case study.

With the ever increasing cost and time required for drug development, new strategies for drug development are highly demanded, whereas repurposing old drugs has attracted much attention in drug discovery. In this paper, we introduce a new network pharmacology approach, namely PINA, to predict potential novel indications of old drugs based on the molecular networks affected by drugs and associated with diseases. Benchmark results on FDA approved drugs have shown the superiority of PINA over traditional computational approaches in identifying new indications of old drugs.

Geometric morphometrics analysis of the hind wing of leaf beetles: proximal and distal parts are separate modules.

The success of beetles is mainly attributed to the possibility to hide the hindwings under the sclerotised elytra. The acquisition of the transverse folding function of the hind wing is an important event in the evolutionary history of beetles. In this study, the morphological and functional variances in the hind wings of 94 leaf beetle species (Coleoptera: Chrysomelinae) is explored using geometric morphometrics based on 36 landmarks.

TCM-Mesh: The database and analytical system for network pharmacology analysis for TCM preparations.

With the advancement of systems biology research, we have already seen great progress in pharmacology studies, especially in network pharmacology. Network pharmacology has been proven to be effective for establishing the "compounds-proteins/genes-diseases" network, and revealing the regulation principles of small molecules in a high-throughput manner, thus would be very effective for the analysis of drug combinations, especially for TCM preparations. In this work, we have proposed the TCM-Mesh system, which records TCM-related information collected from various resources and could serve for network pharmacology analysis for TCM preparations in a high-throughput manner (http://mesh.

[Predation of Poratrioza sinica Yang Li by the adults of Coccinella septempunctata.].

To study predation by Coccinella septempunctata adults on 4 stages of Poratrioza sinica Yang Li, predation functional response, mutual interference, density influence and preference of C. septempunctata on P. sinica were investigated in laboratory and preying effect in field.

Genetic relationships of introduced Colorado potato beetle Leptinotarsa decemlineata populations in Xinjiang, China.

The Colorado potato beetle (CPB), Leptinotarsa decemlineata (Say), is an infamous invasive species worldwide that aggressively attacks potato and other Solanaceae crops. CPB was first found in China in 1993 and has since spread across 2.77 × 10(5) km(2) in Xinjiang Uygur Autonomous Region.

Threat and management strategies of potentially invasive insects in China.

The Global Invasive Species Database, GISD, comprises 27 species of the most significant invasive alien insects in the world (through November, 2005), 6 of which are originally native to China, 11 are established in China, and 10 have a potential invasion threat to China. This paper discusses these species in terms of distribution, harmfulness and dispersal ways, and finds that: (i) Information regarding invasive insects in the GISD remains inadequate. Such harmful invasive species as Opogona sacchari (Bojer), Oracella acuta (Lobdell), and Dendroctonus valens LeConte are not included.

[Research progress on biology and ecology of Harmonia axyridis Pallas (Coleoptera: Coccinellidae)].

Harmonia axyridis Pallas (Coleoptera: Coccinellidae) with its native in Asia is one of the most important predatory ladybird beetles, and used worldwide as a biological control agent. This paper summarized the recent decades research progress at home and abroad on its life history, reproductive strategies, and predatory and cannibalism behaviors, and analysed the prospects of its utilization. Based on the review of its artificial reproduction, insecticide interaction, and impact as an invasive species, some useful measures were suggested to prevent the beetle from its potential risk to ecological banlance.
