Mammalian interleukin-13 (IL-13) is an important regulatory T2 cytokine secreted by activated T lymphocytes. The IL-13 receptor (IL-13R) has two different chains, IL-13Ralpha1 and IL-13Ralpha2. Although the chicken IL-13 gene is well characterized, little is known about IL-13Rs. We cloned a cDNA encoding the 380 amino acid pro-peptide of chicken IL-13Ralpha2 (chIL-13Ralpha2) and developed a mon...

Photoelectron spectroscopy and ab initio calculations are used to investigate the structures and chemical bonding of the B25(-) cluster. Global minimum searches reveal a dense potential energy landscape with 13 quasi-planar structures within 10 kcal/mol at the CCSD(T)/6-311+G(d) level of theory. Three quasi-planar isomers (I, II, and III) are lowest in energy and nearly degenerate at the CCSD(T...

Inflammatory bowel diseases (IBD) including most important forms; Crohn’s disease (CD) and ulcerative colitis (UC); are chronic diseases affecting the gastrointestinal tract with unclear etiology and pathology. The role of gut microbiota has recently been considered as major a factor, since altered microbiome or "dysbiosis" is a key player in the protracted course of inflammation in IBD. Howeve...

In this work, we dissect the performance of  two modern Perdew-Burke-Ernzerhof (PBE)-based double-hybrid (DH) density functionals to predict the isotropic and anisotropic polarizabilities of water nanoclusters (H2O)n [n = 2-6]. The considered models include the cubic integrand (CI) and quadratic integrand (QI) functions as well as the spin-opposite-scaled...

The Mg(BiO2)2 is the orthorhombic crystal system acting as semiconductor in electric devices. To evaluate electronic band structures, the total density of state (TDOS) and the partial density of state (PDOS), Generalized Gradient Approximation (GGA) based on the Perdew–Burke–Ernzerhof (PBE0) was used for Mg(BiO2)2. The band gap was recorded at 0.959 eV, which is supported by a good semiconducto...

Developing efficient photocatalysts for clean energy generation is crucial to achieving net-zero emissions. To this end, we investigate the behavior of photoexcited charges in bismuth oxyhalides BiOX (X = F, Cl, Br, and I), a family inexpensive promising photocatalysts. model localization excess electrons holes, use hybrid density functional theory PBE0(α). Our results indicate that electron po...
