Green synthesis of AgNP-ligand complexes and their toxicological effects on Nilaparvata lugens.

Background: Despite developments in nanotechnology for use in the pharmaceutical field, there is still a need for implementation of this technology in agrochemistry. In this study, silver nanoparticles (AgNPs) were successfully prepared by a facile and an eco-friendly route using two different ligands, 2'-amino-1,1':4',1″-terphenyl-3,3″,5,5″-tetracarboxylic acid (HL) and 1,3,6,8-tetrakis (p-benzoic acid)-pyrene (TBAPy), as reducing agents. The physiochemical properties of the as-obtained AgNPs were characterized by scanning electron microscopy (SEM), energy-dispersive X-ray (EDX), X-ray diffraction (XRD) and transmission electron microscopy (TEM).

Investigation of Physicochemical Indices and Microbial Communities in Termite Fungus-Combs.

species are wild edible mushrooms that possess high nutritional value and a wide range of medicinal properties. However, the cultivation of these mushrooms is very difficult because of their symbiotic association with termites. In this study, we aimed to examine the differences in physicochemical indices and microbial communities between combs with basidiomes (CF) and combs without basidiomes (CNF).

Multipartite symbioses in fungus-growing termites (Blattodea: Termitidae, Macrotermitinae) for the degradation of lignocellulose.

Fungus-growing termites are among the most successful herbivorous animals and improve crop productivity and soil fertility. A range of symbiotic organisms can be found inside their nests. However, interactions of termites with these symbionts are poorly understood.

Termitomyces heimii Associated with Fungus-Growing Termite Produces Volatile Organic Compounds (VOCs) and Lignocellulose-Degrading Enzymes.

Termitomyces fungi associated with fungus-growing termites are the edible mushrooms and can produce useful chemicals, enzymes, and volatile organic compounds (VOCs) that have both fuel and biological potentials. To this purpose, we examined the Termitomyces mycelial growth performance on various substrates, clarified lignocellulose-degrading enzyme activity, and also identified the VOCs produced by Termitomyces. Our results indicated that the optimal nutrition and condition requirements for mycelial growth are D-sorbitol, D-(+)-glucose, and D-(-)-fructose as carbon sources; peptone as well as yeast extract and ammonium tartrate as nitrogen sources; and Mn, Na, and Mg as metal ions with pH range from 7.

Laboratory and Field Evaluation of Multiple Compound Attractants to Culex pipiens pallens.

Efforts to develop mosquito attractants using vertebrate host volatiles have been well made under laboratory conditions but their attractiveness to mosquitoes in the wild still needs to be evaluated. In the present study, we evaluated the attraction of female Culex pipiens pallens Coquillett (Diptera: Culicidae) to 11 individual chemical compounds found in vertebrate host odors, and to synthetic blends, consisting of different combinations of the compounds. These tests were conducted under laboratory and field conditions using a Y-tube olfactometer and odor-baited traps, respectively.

Synthesis, characterization and efficacy of silver nanoparticles against Aedes albopictus larvae and pupae.

Silver nanoparticles have been studied in a wide range of medical and entomological research works due to their eco-friendly aspects. In our study salicylic acid (SA) and its derivative, 3,5-dinitrosalicylic acid (DNS), were used in a one-step synthesis of silver nanoparticles (AgNPs). First, UV-vis absorption spectroscopy was used to detect the formation of AgNPs.

Larvicidal and pupicidal evaluation of silver nanoparticles synthesized using Aquilaria sinensis and Pogostemon cablin essential oils against dengue and zika viruses vector Aedes albopictus mosquito and its histopathological analysis.

Mosquitoes pose a threat to humans and animals, causing millions of deaths every year. Vector control by effective eco-friendly pesticides of natural origin is a serious issue that requires urgent attention. The employment of green-reducing extracts for nanoparticles biosynthesis in a rapid and single-step process represents a promising strategy.

Controlling Aedes albopictus and Culex pipiens pallens using silver nanoparticles synthesized from aqueous extract of Cassia fistula fruit pulp and its mode of action.

Mosquitoes act as key vector for transmission of devastating parasites and pathogens which affect millions of people globally. In this research, the green synthesis of silver nanoparticles of Cassia fistula fruit pulp as an innovative and operative tool against vector mosquitoes is presented. Silver nanoparticles were characterized by a series of techniques including Fourier transform infrared spectroscopy, Transmission Electron Microscope and confirmed by Scanning Electron Microscope, UV-Vis spectrophotometry and X-ray diffraction.

Transfusion-related acute lung injury after transfusion of pooled immune globulin: a case report.

Background: Transfusion-related acute lung injury (TRALI) is a severe transfusion reaction that manifests as acute respiratory compromise within 6 hours of the infusion of blood products. Intravenous immune globulin (IVIG) is prepared from large pools of human plasma and is commonly administered in the outpatient setting for the treatment of a wide range of diseases. As a plasma-derived blood product, IVIG may also cause TRALI, although reports of this are exceedingly rare.

Some observations on the Inb antigen and evidence that anti-Inb causes accelerated destruction of radiolabeled red cells.

This report describes an example of anti-Inb, a red cell alloantibody directed against a high-frequency antigen, detected in a prenatal sample obtained from a Canadian woman of Asian Indian extraction. Although the antibody is IgG1, it could not be detected in the serum or on the red cells (RBCs) of her In(b+) infant. Evidence is provided that the Inb antigen is denatured by papain, ficin, trypsin, bromelin, cystein-activated papain/dithiothreitol, 6 percent aminoethylisothiouronium, and 50 mM dithiothreitol, but not by neuraminidase.

Studies on the catalytic hydrogenation of biomembranes. Hydrogenation of phosphatidylcholine liposomes by two water-soluble rhodium-phosphine catalysts.

The reactions of two water-soluble amphiphiolic rhodium-phosphine hydrogenation catalysts, chlorotris(sodium diphenylphosphinobenzene-m-sulfonate)rhodium(I) and chlorotris(bissodium diphenylphosphinoundecylphosphate)rhodium(I), with aqueous dispersions of unsaturated phosphatidylcholines have been studied. Under mild reaction conditions (pH2 = 1.2 atm, 37 degrees C, pH 6.

Organometallic and organometalloid compounds as standards for microprobe analysis of epoxy resin embedded tissue.

X-ray microanalysis of phosphorus, transition elements and heavy metals in biological tissue is frequently carried out on thin sections of specimens embedded in epoxy resin. A logical choice for the quantitive microprobe analysis of these specimens is a standard, consisting of a homogenous solution of the elements of interest in the epoxy resin. Four kinds of compounds were found suitable for this purpose: (1) phenyl compounds containing group Vb elements, (2) cyclopentadienyl-derivatives, (3) a pentanedione derivative (acetylacetonate) and (4) complexes of metals with dialkyldithiocarbamates.
