A photochem. tunable photonic crystal was prepared by infiltration of the polymer liquid crystal (LC) having azo-chromophores in a SiO₂ inverse opal structure. The SiO₂ inverse opal film infiltrated with the polymer LC reflected a light corresponding to the periodicity as well as the refractive indexes of the inverse opal structure. Linearly polarized light irradiation caused the shift of the reflection band to longer wavelength >15 nm. This is caused by the formation of uniaxially anisotropic mol. orientation of the polymer LC. The switched state was stable under interior light, and reversible switching of the reflection band can be achieved by the linearly and circularly polarized light irradiation This photoswitching property will be suitable not only for various optical materials, but also for introduction of defects in the photonic crystals.

Shirota, Tomomi published the artcilePhotoswitching Behavior of SiO2 Inverse Opal Films Infiltrated with Azo-Tolane Copolymer: Effect of Polymer Main Chain Structure, HPLC of Formula: 135529-02-1, the publication is Molecular Crystals and Liquid Crystals (2009), 79-88, database is CAplus.

Phototunable photonic band gap materials were prepared by infiltration of a liquid crystalline azopolymer into voids of a SiO2 inverse opal film. Linearly polarized light irradiation resulted in a reversible and stable shift of the reflection band to longer wavelength region due to the transformation of azobenzene groups from random to anisotropic mol. orientation. Acrylate and methacrylate copolymers having both azobenzene and tolane groups in side chain have been synthesized in order to improve switching property. Upon irradiation of linearly polarized light SiO2 inverse opal film infiltrated with methacrylate copolymer showed a larger wavelength shift of the reflection band compared to that of the composite film infiltrated with acrylate copolymer.

Mouri, Emiko published the artcileAssociation behaviors of poly(N-vinylpyrrolidone)-grafted fullerenes in aqueous solution, Application In Synthesis of 3052-61-7, the publication is Journal of Polymer Research (2018), 25(10), 1-10, database is CAplus.

Poly(N-vinylpyrrolidone) (PVP)-grafted fullerenes (PVP-C₆₀ and PVP-C₇₀) were synthesized by iniferter polymerization in order to fabricate water-soluble fullerene containing micelles. PVP-C₆₀ formed micelles with hydrodynamic diameters ranging from 15 to 33 nm. The solubilization of fullerene mols. into the core of the PVP-C₆₀ micelles was also found to control the size of the micelles. By increasing the amount of added fullerene, we gradually increased the micelle size before drastically increasing it to that of 200 nm in hydrodynamic diameter The drastic change occurred at a critical value of the added C₆₀/PVP monomer ratio, almost independently of the mol. weight of PVP.

Suhrkamp, Ina published the artcileOral Dimethyl Fumarate Targets HCA2-Expressing Skin Cells in the Imiquimod Mouse Model, SDS of cas: 624-49-7, the publication is Journal of Investigative Dermatology (2022), 142(9), 2547-2550.e5, database is CAplus and MEDLINE.

Fumarates (fumaric acid esters, FAEs) are orally administered systemic agents used for the treatment of psoriasis and multiple sclerosis. DMF therapy typically improves skin inflammation within the first 3 mo of treatment. The aim of this study was to evaluate pharmacokinetic parameters of fumaric acid esters (FAE) in psoriasis patients for the first time. Flow cytometry was used to assess T-cell and neutrophil frequencies, apoptosis and activation phenotype. Our results reveal a novel in vivo effect of DMF therapy on pro-inflammatory neutrophils that likely contributes to this treatments antipsoriatic efficacy.

CB₂ receptor selective ligands are becoming increasingly attractive drugs due to the potential role of this receptor in several physiopathol. processes. Thus, the development of our previously described series of 4-oxo-1,4-dihydroquinoline-3-carboxamides, e.g. I, was pursued with the aim to further characterize the structure-affinity and structure-functionality relationships of these derivatives The influence of the side chain was investigated by synthesizing compounds bearing various carboxamido and keto substituents. On the other hand, the role of the quinoline central scaffold was studied by synthesizing several 6-, 7-, or 8-chloro-4-oxo-1,4-dihydroquinolines, as well as 4-oxo-1,4-dihydronaphthyridine and 4-oxo-1,4-dihydrocinnoline derivatives The effect of these modifications on the affinity and functionality at the CB₂ receptor was studied and allowed for the characterization of new selective CB₂ receptor ligands.

Maruyama, Taiki published the artcileMultifunctional 3D Printing of Heterogeneous Polymer Structures by Laser-Scanning Micro-Stereolithography Using Reversible Addition-Fragmentation Chain-Transfer Polymerization, HPLC of Formula: 3052-61-7, the publication is ACS Applied Polymer Materials (2022), 4(8), 5514-5522, database is CAplus.

Stereolithog. is the most precise three-dimensional (3D) printing technol. and has been applied to various applications with various photocurable materials. However, most 3D-printed objects produced using conventional methods are made of uniform materials, limiting their functions. In this study, to produce heterogeneous 3D-printed objects, microphase-separated structures were controlled by the copolymerization of a photoinduced macro-reversible addition-fragmentation chain-transfer (macro-RAFT) agent and a monomer at different scanning speeds of an UV laser beam using a laboratory-constructed laser-scanning micro-stereolithog. system based on a bottom-up configuration in a fully open-to-air system. First, we demonstrated 3D printing using a RAFT agent by fabricating a pyramidal structure using a 375 nm laser. Copolymerization with styrene was performed to confirm that the synthesized poly(Bu acrylate) with dormant species at the end (DTC-PBA) formed block polymers upon photoirradiation NMR and gel permeation chromatog. (GPC) results indicated the formation of a block polymer. A homogeneous photocurable resin was prepared by mixing the synthesized DTC-PBA with multi-functional monomers, and 3D printing was performed using the prepared photocurable resin at different scanning speeds. As the scanning speed increased, the transparency of the 3D-printed model increased, whereas the mech. strength decreased. It was suggested from scanning probe microscopy (SPM) observations that these differences were due to differences in the microphase-separation structure. As a result, it was demonstrated that heterogeneous 3D structures with sites have different mech. and optical properties from those of a single material. Controlling the phys. properties of 3D-printed parts by controlling the laser irradiation conditions is useful for functionalizing 3D-printed microdevices.

Dreyer-Alster, Sapir published the artcileCOVID-19 vaccination in patients with multiple sclerosis: Safety and humoral efficacy of the third booster dose, Related Products of esters-buliding-blocks, the publication is Journal of the Neurological Sciences (2022), 120155, database is CAplus and MEDLINE.

As immunity against SARS-COV-2 wanes following first and second doses of vaccination, a third dose is administered in several countries around the world. Similarly to the first doses, risks related to vaccination and humoral immune response in patients with multiple sclerosis (MS) need to be assessed. Characterize safety and humoral immune response following the third dose of COVID-19 vaccination in a large cohort of MS patients. We assessed the safety of the third dose of the BNT162b2-COVID-19 mRNA vaccination in adult MS patients and evaluated SARS-CoV-2 IgG response. Two hundred and eleven adult MS patients received a third dose of BNT162b2 COVID-19 vaccination. Median follow up time was 66 days from vaccine administration (IQR 54-84). The frequency of any adverse event was 54.5%, with the most common reported adverse events being fatigue, local pain at the injection site, fever and muscle or joint pain. Transient increase in MS symptoms was reported in 3.8% of patients, none of them requiring treatment. The rate of acute relapses treated with IV steroids was 3.3%. In a sub-group of 55 patients, 20 untreated and 35 treated with vaccination-safe disease-modifying treatments, SARS-CoV-2 IgG levels increased 21-fold (median ± SD 21.6 ± 53.05). The third dose of COVID-19-BNT162b2 vaccine proved safe for MS patients, with no increased risk of relapse activity. Untreated patients and patients treated with vaccination-safe disease-modifying treatments show significant increase in SARS-CoV-2 IgG levels following the third dose of vaccination.
