Feeding and bone traits are vital for breeding and reproduction in the commercial duck industry. In this study, we performed a genome-wide association study for feeding and bone traits in a population of 540 lean-type Pekin ducks, followed by genotyping-by-sequencing procedures. The genetic parameters of feeding and bone traits were also estimated using genomic information. In total, seventy-eight significant SNPs were determined, and eleven of them reached the genome-wide significant level for 7 traits except for body weight at 42-day old. A peak of genome-wide significant SNPs was detected on chromosome 2 for feed conversion ratio (P-value = 7.46E-11), and the top SNP (P-value = 2.23E-08) for bone-breaking strength was also obtained in the upstream of gene RAPGEF5. This study provided a list of novel markers and candidate genes associated with feeding and bone traits in Pekin ducks, which could contribute to the genetic selection in duck breeding.
Ulcerative colitis (UC) is an inflammatory disorder of the colon. Garcinia mangostana Linn. (GM) has been traditionally used for its anti-inflammatory and antioxidant activities.

The effects of GM and its bioactive constituent α-mangostin on dextran sulfate sodium (DSS)-induced UC in mice were investigated.

Adult ICR mice (n=63) were pretreated with ethanolic GM extract at 40, 200, and 1000mg/kg/day (GM40, GM200, and GM1000), α-mangostin at 30mg/kg/day, or sulfasalazine at 100mg/kg/day (SA) for 7 consecutive days. On days 4-7, UC was induced in the mice by the oral administration of DSS (40kDa, 6g/kg/day), while control mice received distilled water. The UC disease activity index (DAI) and histological changes were recorded. The activities of myeloperoxidase, catalase, and superoxide dismutase, and the levels of reactive oxygen species (ROS), nitric oxide (NO), and malondialdehyde (MDA) were determined. The mRNA expression of inflammatory related genes including proinflammatory cytokine Tnf-α, Toll-like receptor (Tlr-2), adhesion molecules (Icam-1 and Vcam-1), and monocyte chemoattractant protein (Mcp-1) were evaluated.

Treatment with GM or α-mangostin decreased the UC DAI and protected against colon shortening and spleen and kidney enlargement. GM and α-mangostin prevented histological damage, reduced mast cell infiltration in the colon, and decreased myeloperoxidase activity. GM and α-mangostin increased catalase and superoxide dismutase activity and decreased ROS, NO, and MDA production. GM downregulated mRNA expression of Tnf-α, Tlr-2, Icam-1, Vcam-1, and Mcp-1.

GM and α-mangostin attenuated the severity of DSS-induced UC via anti-inflammatory and antioxidant effects. Therefore, GM is a promising candidate for development into a novel therapeutic agent for UC.

The effect of two sugars, trehalose and melibiose, on the recrystallization of amorphous paracetamol, and vice versa, was investigated. The solid dispersions were prepared via heating and quench-cooling, and then stored at a temperature of 38.5 ± 0.5 °C and relative humidities of 3 ± 1% and 75 ± 1%. X-ray powder diffraction (XRPD) confirmed that the solid dispersions were amorphous, while Fourier-transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC) revealed that the solid dispersions were two-phase systems with drug-rich and excipient-rich regions. XRPD was used to qualitatively and quantitatively study the crystallization of the components, and revealed that, despite the existence of two phases, the sugars hindered the crystallization of paracetamol. In contrast, once the paracetamol crystallization started, it accelerated the crystallization of the sugars. Overall, the study demonstrates that small-molecule solid-dispersions need not be single-phase to observe mutual influences between the components in crystallization behavior, and that these effects are likely mediated through interactions at the phase interfaces, as well as alterations in water sorption and mechanical effects.The tensile test is the most widely used method for testing the mechanical characteristics of orally disintegrating films (ODFs). The other available test is the folding endurance (FE) test, which is more suitable for clarifying the actual strength during the manufacturing and dosing. However, the FE test is performed manually, and the FE number it generates has not been adequately analyzed as an index. The aim of this studies were to establish an automatic method for determining the FE number, and to compare the resulting FE numbers with the tensile properties. For this purpose, a desktop-model endurance test machine was used. First, the operating conditions-i.e., the folding angle, the folding speed and the weight requirement were optimized using ODF models. Secondly, the FE of ODFs prepared from three film formers (HPMC, HPC, and PVA) and with insoluble particles (calcium carbonate), plasticizers (glycerin) and APIs (acetaminophen), was evaluated and compared with the tensile properties. Lastly, the commercial ODFs were investigated. The results showed that our automatic system could be successfully used to determine the FE characteristics of ODFs. FE was suggested to relate to not only the strength but also the elongation during the tensile test.The limited therapeutic option for respiratory infections caused by multi-drug resistant microbial pathogens is a major global health threat. Topical delivery of antibacterial combinations to the lung could dramatically enhance antibacterial activities and provide a means to overcome bacterial resistance development. The aim of the study was to investigate the potential of new inhalable dry powder combinations consisting of a fixed dose of aztreonam (Azt) and tobramycin (Tob) using a spray drying process, against antibiotic resistant Gram-negative respiratory pathogens. The interactions of Azt with Tob on resistant Pseudomonas aeruginosa, Klebsiella pneumoniae and Acinetobacter baumannii were determined by calculating factional inhibitory concentration indices (FICI). A fixed concentration ratio of Azt and Tob that exhibited a synergistic antimicrobial effect was selected and formulated into inhalable dry powders by co-spray drying with and without L-leucine. Selleck OUL232 The obtained dry powders were characterized with respect to the morphology, particle size distribution, solid state, moisture sorption behaviour, and in vitro dissolution.
