Semi-interpenetrating network based on xanthan gum-cl-2-(N-morpholinoethyl methacrylate)/titanium oxide for the single and binary removal of cationic dyes from water.

In the present study, semi-interpenetrating polymer networks (semi-IPNs) were synthesized based on xanthan gum (XG)-cl-2-(N-morpholinoethyl methacrylate) (MEMA)/titanium dioxide (TiO) in the presence of N, N` methylene bisacrylamide (MBAAm), as the cross-linking agent. After that, the semi-IPN hydrogel was used to adsorb Methylene Blue (MB) and Crystal Violet (CV) from single and two-component adsorption systems. The optimal pH for efficient dye adsorption in aqueous solutions has been determined to be 8 for CV and 11 for MB, respectively.

Production of LMWH-conjugated core/shell hydrogels encapsulating paclitaxel for transdermal delivery: In vitro and in vivo assessment.

Topical applications that reduce systemic toxic effects while increasing therapeutic efficacy are a promising alternative strategy. The aim of this study was to provide an enhanced transdermal delivery of low molecular weight heparin (LMWH) through the stratum corneum by using cationic carrier as a novel permeation enhancer. Recent studies have shown that heparin-conjugated biomaterials can be effective in inhibiting tumor growth during cancer treatment due to their high ability to bind growth factors.

Microwave-assisted hydrogenation of codeine in aqueous media.

An efficient one-pot microwave-assisted hydrogenation of codeine was achieved in aqueous solution. This technique is simple, fast, environmentally friendly, and highly efficient. Structure of produced dihydrocodeine was approved by using FT-IR, (1)H NMR, (13)C NMR, EIMS, and elemental analysis technique.

[Focus on the various techniques of anaesthesia in ophthalmologic surgery].

Ophthalmologic surgery is not a vital one. It mostly concerns patients in extreme ages: children and old people. The risk of anaesthesia mainly depends on the health conditions of the patient.
