Growing evidence indicates that the Toll-like receptor7/8(TLR7/8) agonist resiquimod (R848) is a potential inhibitor of type-2 immunity. However, the mechanisms mediating its therapeutic effects are not fully understood. This study investigated the effects of R848 on OVA-induced allergic rhinitis(AR) mice and the expression of IL-25, IL-33, TSLP, T-cell immunoglobulin mucin1 (TIM1) and T-cell immunoglobulin mucin3 (TIM3). BALB/c mice were intranasally sensitized and challenged with ovalbumin (OVA), and R848 was intraperitoneally injected into AR mice...

Purpose: To compare the agreement between optical coherence tomography (OCT)-based choroidal vascularity markers measured by two previously reported image binarization techniques. Methods: Spectral-domain OCT using enhanced-depth imaging was performed in 100 eyes from 52 normal subjects. Choroidal images were binarized to luminal area and stromal area using two different algorithms. Choroidal vascularity marker was defined as the ratio of luminal area to total choroidal area and they were termed "luminal/choroidal area ratio (L/C ratio)" and "choroidal vascularity index (CVI)" per the algorithm...

BACKGROUND AND OBJECTIVES: Pulmonary pleomorphic carcinoma (PPC) is a rare and aggressive subtype of lung cancer. Programmed cell death-ligand 1 (PD-L1) expression may be induced in a variety of malignant tumors, but its prognostic implication in PPC remains unclear. METHODS: Twenty-six patients with surgically resected PPC were retrospectively reviewed. Immuno-histochemical staining was used to detect PD-L1 expression, and PD-L1 status was classified into "high" or "low" according to the percentage of tumor cells (TCs) expressing PD-L1 (tumor proportion score, TPS)...

Three-dimensional time-of-flight (TOF) magnetic resonance angiography (MRA) can reliably detect dural arteriovenous fistula (dAVF); however, TOF source images should be checked in cases with low-flow dAVFs. A 69-year-old woman reported intractable pulsatile tinnitus after head trauma. It was difficult to diagnose dAVF using conventional MRA, but it was confirmed using a TOF source image. Cerebral angiography revealed a dAVF with a small shunted pouch draining into the sigmoid sinus, accompanying the arterial jet flow...

AIM: To determine whether there is a significant correlation between the reduction in macular vessel density and the recurrence of macular oedema in eyes with branch retinal vein occlusion (BRVO). METHODS: We reviewed the medical records of 27 eyes with macular oedema associated with BRVO. All eyes had received pro re nata intravitreal ranibizumab (IVR) injection. A reinjection of ranibizumab was performed when the central foveal thickness was ≥300 µm. At 12 months, patients without additional IVR for the last 4 months were placed in the resolved group, otherwise they were placed in the recurrence group...

In general, thyroid hormones (THs) stimulate cellular metabolism by inducing ATP utilization that collaterally leads to thermogenesis. However, in cetaceans, TH functions and the contribution of THs to cold adaptation are not fully understood. To investigate the role of THs in metabolism of cetaceans, seasonal changes in circulating levels in thyroxine (T4 ) were investigated in the common bottlenose dolphin Tursiops truncatus that were monitored under two different conditions for two years, with routine measurements of body temperature (BT), water temperature (WT) and air temperature (AT)...

Disilaferra- and disilaruthenacyclic complexes containing mesityl isocyanide as a ligand, 3' and 4', were synthesized and character-ized by spectroscopy and crystallography. Both 3' and 4' showed good catalytic activity for the hydrogenation of alkenes. Com-pared with the iron and ruthenium carbonyl analogs, 1' and 2', the isocyanide complexes 3' and 4' were more robust under the hydrogenation conditions, and were useful even at higher temperatures (~80 °C) under hydrogen pressure (~20 atm). The iron complex 3' possessed the highest catalytic activity toward hydrogenation of mono-, di-, tri-, and tetrasubstituted alkenes among iron catalysts reported...

Four novel chiral iridium(iii) complexes with triplex stereogenic centers were synthesized by introducing chiral carbon atoms into cyclometalated and ancillary ligands, and separated into eight isomers, which coincide with the old Chinese philosophy Eight Trigrams. The electron circular dichroism and circularly polarized luminescence spectra of four pairs of isomers show perfect mirror images with a dissymmetry factor (glum factor) of around 0.003.

6-Tuliposide B (PosB), a major secondary metabolite that accumulates in tulip (Tulipa gesneriana), is converted to the antibacterial lactone, tulipalin B (PaB), by PosB-converting enzyme (TCEB). TgTCEB1 and TgTCEB-R, which encode TCEB, are specifically expressed in tulip pollen and roots, respectively, but are hardly expressed in other tissues (e.g. leaves) despite the presence of substantial PosB-converting activity, suggesting the existence of another TCEB isozyme. Here, we describe the identification of TgTCEB-L ("L" for leaf), a paralog of TgTCEB1 and TgTCEB-R, from leaves via native enzyme purification...
