Veterinary Dermatology, Volume 34, Issue 3, Page 235-245, June 2023., 2023 Background – Oral and parenteral drug delivery in horses can be difficult. Equine‐specific transdermal drug formulations offer improved ease of treatment; development of such formulations requires a deeper understanding of the structural and chemical tissue barrier of horse skin. Hypothesis/Objectives – To compare the structural composition and barrier

Journal of Diabetes, Volume 15, Issue 2, Page 165-180, February 2023., 2023 Highlights For the first time, our study contributed a systematic evaluation of bile acid (BA) profiles in plasma, feces and liver tissue and gut microbiota changes triggered by fasting‐refeeding cycle in mice. Our work clearly demonstrated that overnight fasting leads to significant, but reversible changes in BA profiles and gut microbiota composition.

Veterinary Dermatology, Volume 32, Issue 5, Page 456-e124, October 2021., 2021 Background – Ceftazidime (CAZ) solutions are being used based on anecdotal reports for otitis externa complicated by multidrug‐resistant Pseudomonas aeruginosa (MDR PA). The chemical and microbiological stability of these proposed compounded solutions have not been evaluated, and likely are affected by the diluent and storage duration or temperature ...

Thermal stability of hydrocarbon fuel under supercritical condition(碳氢燃料的超临界热稳定性研究)
Zhejiang Daxue xuebao. Lixue ban, 2013 以正壬烷为碳氢燃料模型化合物，考察其在超临界条件下的恒容热裂解，跟踪裂解转化率和产物分布，探讨了反应温度和时间对燃料热稳定性的影响.正壬烷热裂解气体产物主要有甲烷、乙烷、乙烯、丙烷和丙烯；液态产物中则以链烷烃、烯烃和环烷烃为主，并可检测到芳烃.采用高效液相色谱(HPLC)法测定了液体产物中芳烃的含量，与气相色谱-质谱联用(GC-MS)和紫外-可见光谱(UV-vis)测定结果相互印证，芳烃含量随裂解转化率增加呈指数变化，表达了燃料热稳定性和裂解规律的变化趋势.
