Abstract Background The human monoclonal antibody dupilumab blocks interleukin (IL)‐4 andIL‐13, key and central drivers of type 2 inflammation. Dupilumab, on background mometasone furoate nasal spray (MFNS), improved outcomes in the phase III SINUS‐52 study (NCT02898454) patients with severe chronic rhinosinusitis polyps (CRSwNP). This posthoc analysis examined whether eosinophilic status CRSwNP was a predictor efficacy. Methods Patients were randomized 1:1:1 to 300 mg every weeks (q2w)...

The antiobesity effects of Chinese black tea (Pu‐erh tea) and gallic acid (GA) were investigated using in vitro vivo assays. extract (BTE) GA inhibited pancreatic lipase activity a dose‐dependent manner ; the IC(inhibitory concentration) 50 values 101.6 9.2 µg/mL, respectively. Black (50, 100 mg/kg body weight (b.w.)) (15, 45 b.w.) significantly suppressed elevation blood triglyceride after oral administration corn oil emulsion (8 mL oil/kg to male ddY mice. Moreover, BTE also evaluated...

Although growth differentiation factor-5 (GDF5) has been implicated in skeletal development and joint morphogenesis mammals, little is known about its functionality adipogenesis energy homeostasis. Here, we show a critical role of GDF5 regulating brown for systemic expenditure mice. expression was preferentially upregulated adipose tissues from inborn acquired obesity Transgenic overexpression led to lean phenotype reduced susceptibility diet-induced through increased expenditure....

Objectives/Hypothesis Dupilumab, which blocks the shared receptor component for interleukin‐4 and interleukin‐13, reduced polyp size, sinus opacification, symptom severity, was well tolerated in patients with chronic rhinosinusitis nasal polyps (CRSwNP) SINUS‐52 study (NCT02898454). We assessed dupilumab enrolled at Japanese centers. Methods Patients on a background of mometasone furoate spray, received 300 mg every 2 weeks (q2w) 52 (Arm A); q2w 24 weeks, followed by 4 (q4w) 28 B); or...

Zinc ions (Zn2+) are vital to most cells, with the intracellular concentrations of Zn2+ being tightly regulated by multiple zinc transporters located at plasma and organelle membranes. We herein present 2.2-3.1 Å-resolution cryo-EM structures a Golgi-localized human Zn2+/H+ antiporter ZnT7 (hZnT7) in Zn2+-bound unbound forms. Cryo-EM analyses show that hZnT7 exists as dimer via tight interactions both cytosolic transmembrane (TM) domains two protomers, each which contains single Zn2+-binding...

The radiofrequency (RF) receive array coil is a complicated device with many inductors and capacitors serves as one of the most critical magnetic resonance imaging (MRI) electronic devices. It directly determines achievable level signal-to-noise ratio (SNR). Simply put, however, RF nothing but an LC circuit. was first proposed more than 20 years ago, evolving from simple arrangement few channels to system 128 channels, enabling highly sophisticated parallel imaging, at different field...

Poly(3-hexylthiophene) (P3HT) with a bromobutyl functional group at the ω-chain-end (P3HT-C4Br) and P3HT groups α,ω-chain-ends (BrC4-P3HT-C4Br) were synthesized by selecting appropriate initiators for Grignard metathesis (GRIM) polymerization. The high end-functionality was confirmed matrix assisted laser desorption-ionization time-of-flight (MALDI–TOF) mass spectrometry. These polymers efficiently reacted living anionic of 4-(4′-N,N-dihexylaminophenylethynyl)styrene (DHPS) to yield novel...

The P3HT:PCBM (P3HT = poly(3-hexylthiophene, PCBM phenyl-C61-butyric acid methyl ester) bulk-heterojunction (BHJ) organic photovoltaic (OPV) cells using the AB diblock and ABA triblock copolymers (A polystyrene derivative with donor-acceptor units (PTCNE) B P3HT) as compatibilizers were fabricated. Under optimized blend ratio of block copolymer, power conversion efficiency (PCE) was enhanced. This PCE enhancement clearly related to increased short-circuit current (J(sc)) fill factor (FF)....

Poly(3-hexylthiophene) (P3HT)-segment-based block copolymers have been reported to deliver an effective compatibilizer function in the P3HT:PC61BM bulk-heterojunction (BHJ) system simultaneously improve performance and stability. However, as limited by deficient optophysic properties of system, resultant power conversion efficiency (PCE) compatibilizer-mediated devices is low despite optimized chemical structures P3HT-segment-based copolymers. To better shed light on such a effect, herein...
