J Colloid Interface Sci 2018 Dec 4;538:559-568. Epub 2018 Dec 4.

Department of Pharmacy, University of Copenhagen, Universitetsparken 2, DK-2100 Copenhagen, Denmark; Department of Pharmacy, University of Uppsala, SE-75123 Uppsala, Sweden.

In an effort to contribute to research in scalable production systems for polymeric delivery systems loaded with antimicrobial peptides (AMPs), we here investigate effects of hydrodynamic flow conditions on microfluidic particle generation. For this purpose, rapid prototyping using 3D printing was applied to prepare micromixers with three different geometric designs, which were used to prepare Ca-cross-linked alginate microgels loaded with the AMP polymyxin B in a continuous process. Based on fluid dynamic simulations, the hydrodynamic flow patterns in the micromixers were designed to be either (i) turbulent with chaotic disruption, (ii) laminar with convective mixing, or (iii) convective with microvortex formation.

One-pot synthesis of hyper-cross-linked polymers chemically modified with pyrrole, furan, and thiophene for phenol adsorption from aqueous solution.

J Colloid Interface Sci 2018 Dec 6;538:499-506. Epub 2018 Dec 6.

College of Chemistry and Chemical Engineering, Central South University, Changsha 410083, China.

Pyrrole, furan, and thiophene modified hyper-cross-linked polymers (HCPs) were prepared in one-pot method by two successive Friedel-Crafts reactions, and they were assessed by phenol adsorption from aqueous solution. The results indicated that the three chemically modified polymers had lower Brunauer-Emmett-Teller surface area and pore volume than the common HCPs, while the phenol adsorption on the pyrrole and thiophene modified polymers was relatively enhanced due to the introduction of the heteroatoms on the surface. Notably, the enthalpy changes of HCP-Py, HCP-Fu, and HCP-Th were greater than the HCPs, and the introduced heteroatoms provide greater interaction with phenol through dipole-dipole interaction.

This study was focused on analyzing the effects of dietary inclusion of raw chickpea seed as a replacement of soybean meal as a primary protein source on bone structure in broiler chickens. Broiler chickens (n = 160) received in their diet either soybean meal (SBM) or raw chickpea seeds (CPS) as a primary protein source throughout the whole rearing period (n = 80 in each group). On the 42th day randomly selected chickens from each group (n = 8) were slaughtered. Read More

Regulation of phosphorus bioavailability by iron nanoparticles in a monomictic lake.

Sci Rep 2018 Dec 10;8(1):17736. Epub 2018 Dec 10.

Australian Rivers Institute, Griffith University, Griffith, Australia.

Dissolved reactive phosphorous (DRP) in lake systems is conventionally considered to predominate over other dissolved P species, however, this view neglects an important set of interactions that occurs between P and reactive iron hydroxide surfaces. This study addresses the coupling of P with dispersed iron nanoparticles in lakes, an interaction that may fundamentally alter the bioavailability of P to phytoplankton. We used diffusive gradients in thin films (DGT) and ultrafiltration to study Fe-P coupling in the water column of a monomictic lake over a hydrological year. Read More

Pseudomyxoma Peritonei After a Total Pancreatectomy for Intraductal Papillary Mucinous Neoplasm With Colloid Carcinoma in Lynch Syndrome.

Pancreas 2019 Jan;48(1):135-138

Radiology, St Antonius Hospital, Nieuwegein, the Netherlands.

We report a case of pseudomyxoma peritonei (PMP) arising in a 62-year-old male patient with Lynch syndrome (LS). The patient's medical history included an adenocarcinoma of the colon for which a right hemicolectomy was performed and a pancreatectomy due to an intraductal papillary mucinous neoplasm (IPMN) with invasive colloid carcinoma. It was considered that the PMP could be a metastasis of the earlier colonic or pancreatic carcinoma. Read More

remains a deadly disease in small children and the elderly even though conjugate and polysaccharide vaccines based on isolated capsular polysaccharides (CPS) are successful. The most common serotypes that cause infection are used in vaccines around the world, but differences in geographic and demographic serotype distribution compromises protection by leading vaccines. The medicinal chemistry approach to glycoconjugate vaccine development has helped to improve the stability and immunogenicity of synthetic vaccine candidates for several serotypes leading to the induction of higher levels of specific protective antibodies.

DNA nanostructures doped with lanthanide ions for highly sensitive UV photodetectors.

Colloids Surf B Biointerfaces 2018 Dec 1;175:212-220. Epub 2018 Dec 1.

Sungkyunkwan Advanced Institute of Nanotechnology (SAINT) and Department of Physics, Sungkyunkwan University, Suwon, 16419, Republic of Korea. Electronic address:

Deoxyribonucleic acid (DNA) and lanthanide ions (Ln) exhibit exceptional optical properties that are applicable to the development of nanoscale devices and sensors. Although DNA nanostructures and Ln ions have been investigated for use in the current state of technology for more than a few decades, researchers have yet to develop DNA and Ln based ultra-violet (UV) photodetectors. Here, we fabricate Ln (such as holmium (Ho), praseodymium (Pr), and ytterbium (Yb))‒doped double crossover (DX)‒DNA lattices through substrate-assisted growth and salmon DNA (SDNA) thin films via a simple drop-casting method on oxygen (O) plasma-treated substrates for high performance UV photodetectors.
