Two new species of Bryobia (Acarina, Prostigmata, Tetranychidae) from South France.

Two new species of Tetranychidae belonging to the genus Bryobia are reported from France. Bryobiabelliloci sp. n.

Two new species of Aphidini Latreille, 1802 (Hemiptera: Aphididae) from Turkey.

Apterous and alate viviparous females of Protaphis kvavadzei sp. n. on Eryngium campestre (Apiaceae) and Aphis matricariae sp.

New poly(ester urea) derived from L-leucine: electrospun scaffolds loaded with antibacterial drugs and enzymes.

Electrospun scaffolds from an amino acid containing poly(ester urea) (PEU) were developed as promising materials in the biomedical field and specifically in tissue engineering applications. The selected poly(ester urea) was obtained with a high yield and molecular weight by reaction of phosgene with a bis(α-aminoacyl)-α,ω-diol-diester monomer. The polymer having L-leucine, 1,6-hexanediol and carbonic acid units had a semicrystalline character and relatively high glass transition and melting temperatures.

[The effects of grape seed and coriander oil on biochemical parameters of oral fluid in patients with periodontitis].

Biochemical changes that are taking place in patients with periodontitis 1 and 2 the quality of the individuals place in a laqtatdegidrogenazis, alkaline phosphatase activity increase and reduced activity amilazais. Therefore we can conclude that, there is an increase in superoxide substances, which causes an increase in the oral cavity patobakteriebis and quality of periodontitis. The grape seed and coriander oil is of vegetable origin and antioxidant drugs.

A new genus of Macrosiphini Wilson, 1910 (1887) (Hemiptera: Aphididae) from Rhododendron in Turkey.

Rhododendraphis tuatayae gen. n., sp.

Impact of wines and wine constituents on cyclooxygenase-1, cyclooxygenase-2, and 5-lipoxygenase catalytic activity.

Cyclooxygenases and lipoxygenases are proinflammatory enzymes; the former affects platelet aggregation, vasoconstriction, vasodilatation and later the development of atherosclerosis. Red wines from Georgia and central and western Europe inhibited cyclooxygenase-1 (COX-1) activity in the range of 63-94%, cyclooxygenase-2 (COX-2) activity in the range of 20-44% (tested at a concentration of 5 mL/L), and 5-lipoxygenase (5-LOX) activity in the range of 72-84% (at a concentration of 18.87 mL/L).

Arginine-based biodegradable ether-ester polymers with low cytotoxicity as potential gene carriers.

The success of gene therapy depends on safe and effective gene carriers. Despite being widely used, synthetic vectors based on poly(ethylenimine) (PEI), poly(l-lysine) (PLL), or poly(l-arginine) (poly-Arg) are not yet fully satisfactory. Thus, both improvement of established carriers and creation of new synthetic vectors are necessary.

Synthesis, properties and applications of biodegradable polymers derived from diols and dicarboxylic acids: from polyesters to poly(ester amide)s.

Poly(alkylene dicarboxylate)s constitute a family of biodegradable polymers with increasing interest for both commodity and speciality applications. Most of these polymers can be prepared from biobased diols and dicarboxylic acids such as 1,4-butanediol, succinic acid and carbohydrates. This review provides a current status report concerning synthesis, biodegradation and applications of a series of polymers that cover a wide range of properties, namely, materials from elastomeric to rigid characteristics that are suitable for applications such as hydrogels, soft tissue engineering, drug delivery systems and liquid crystals.

Cell compatible arginine containing cationic polymer: one-pot synthesis and preliminary biological assessment.

Synthetic cationic polymers are of interest as both nonviral vectors for intracellular gene delivery and antimicrobial agents. For both applications synthetic polymers containing guanidine groups are of special interest since such kind of organic compounds/polymers show a high transfection potential along with antibacterial activity. It is important that the delocalization of the positive charge of the cationic group in guanidine significantly decreases the toxicity compared to the ammonium functionality.
