Liquid-crystal-imprinted synthesis of chiral polypyrroles without a chiral centre using a two-step method of spark-discharge oligomerisation-electrochemical polymerisation.

Pyrrole in a cholesteric liquid crystal was discharged using a Tesla coil to generate pyrrole radicals, affording linear-shaped nano-ordered pyrrole oligomers. Subsequently, the electrochemical polymerisation of a pre-oriented pyrrole oligomer having good affinity for liquid crystals was performed to achieve polypyrrole-imprinted asymmetry from the cholesteric liquid crystal structure. The resultant polymers were analysed using polarising optical microscopy observations, scanning electron microscopy, electrochemistry, optical spectroscopy, and electron spin resonance.

Impact of Janus kinase inhibitors and methotrexate on interstitial lung disease in rheumatoid arthritis patients.

Objectives: Little is known about how various treatments impact the progression of interstitial lung disease (ILD) in rheumatoid arthritis (RA) patients. Here, we compared ILD progression in RA patients treated with Janus kinase inhibitors (JAKi) or biological disease-modifying anti-rheumatic drugs (bDMARDs). experiments were also performed to evaluate the potential effects of the drugs on epithelial-mesenchymal transition (EMT), a key event in pulmonary fibrosis.

Effect of Regional Anesthesia on Intraoperative Hyperkalemia in Patients With Chronic Kidney Disease: Two Case Reports.

Intraoperative hyperkalemia is particularly common in patients with chronic kidney disease (CKD). We report two cases of intraoperative hyperkalemia occurring under general anesthesia, while potassium levels remained stable with regional anesthesia alone. Case 1 involved a 69-year-old male with CKD who underwent total thyroidectomy under general anesthesia and developed intraoperative hyperkalemia, requiring glucose-insulin (GI) therapy.

Helical magnetism in poly(aniline--ferrocene): structure and magnetism.

This study reports the synthesis and characterisation of a ferrocene-based conjugated polymer and a chiral composite. The precursor copolymer was synthesised from 1,3-phenylenediamine and 1,1'-dibromoferrocene Buchwald-Hartwig polycondensation. This polymerisation process increased the effective conjugation length and led to magnetic spin interactions along the main chain, resulting in a ground triplet spin state at 25 °C.

Effects of switching to dolutegravir/lamivudine from tenofovir alafenamide fumarate/emtricitabine/dolutegravir or abacavir/lamivudine/dolutegravir on body weight and lipid profile in Japanese people living with HIV.

Background: The two-drug regimen of dolutegravir/lamivudine (DTG/3TC) is currently an optional antiretroviral therapy (ART). Despite its reported advantages on body weight and lipid profile, the same effects have not yet been reported for Asian population.

Methods: We conducted a single-center retrospective study involving Japanese people living with HIV (PLWH).
