Next‐Generation Sequencing of Fecal DNA: A Novel Insight Into the Mitogenome Phylogeography of the Snow Leopard (Panthera Uncia) 粪便dna的二代测序:对雪豹线粒体组谱系地理结构的新洞察

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 277-286, September 2025.
This study provides an innovation to address the challenge in accessibility to samples and genetic markers in Snow leopard conservation genetic studies. We performed next‐generation sequencing (NGS) on 19 fecal samples obtained from the eastern Qinghai‐Tibet Plateau, and successfully assembled 17 complete mitogenome sequences (~16,720 bp) and ...

A novel approach for feline sporotrichosis pathogen detection based on loop‐mediated isothermal amplification

open access: yesVeterinary Dermatology, Volume 36, Issue 4, Page 474-484, August 2025.
Background – Sporotrichosis is a chronic, mycotic infection caused by fungi of the genus Sporothrix. Zoonotic sporotrichosis occurs mainly through S. brasiliensis transmission, resulting from the organism's traumatic introduction via scratches or bites, or contact with exudate from contaminated cats.

Comparative efficacy of selenoureido carbonic anhydrase inhibitors and azole antifungal drugs against clinical isolates of Malassezia pachydermatis

open access: yesVeterinary Dermatology, Volume 36, Issue 3, Page 302-313, June 2025.
Background – Malassezia pachydermatis (MP) is implicated in severe dermatitis and otitis externa (OE) of companion animals and recently gained attention for its increasing resistance to azole compounds. For this reason, developing novel therapeutic strategies is of great interest. In a previous work, we used reference yeast isolates to evaluate several

Study on establisment of chicken embryo RNAi technology with infective feature of RCAS and Vezf1 function in chicken vascular development. [PDF]

open access: yes, 2012
早期初级血管网络的形成,始于胚胎中胚层形成过程中其部分细胞分化为血管内皮前体细胞。血管内皮前体细胞再进一步向血管内皮细胞分化并形成初级毛细血管网,血管内皮细胞与其周围细胞进一步相互作用,逐步进行对初级血管的改建和生成新的血管,最终完成血管系统的发育。因此,血管内皮细胞是血管生成的中心细胞。为研究胚胎血管内皮细胞分化机制,先前我们从发育至三体节的鸡内皮前体细胞(VEGFR2+)相对特异表达基因的克隆中,发现了鸡的Vezf1(cVezf1)基因。该基因与在小鼠中发现的Vezf1基因高度同源 ...

Cytological evaluation, culture and genomics to evaluate the microbiome in healthy rabbit external ear canals

open access: yesVeterinary Dermatology, Volume 35, Issue 5, Page 479-491, October 2024.
Background – Lop‐eared rabbits may be predisposed to otitis externa (OE) as a consequence of their ear conformation. Although otoscopy, otic cytological evaluation, and culture are valuable tools in dogs and cats, published data on rabbits remain lacking. Hypothesis/Objectives – This study aimed to assess the utility of otoscopy and cytological results

Studies on Kinmen kaoliag liquor brewing system and the application of its secondary production- yellow water [PDF]

open access: yes, 2015
在酿酒过程中,高粱是决定白酒质量优劣的重要因素。高粱中淀粉含量越多,出酒率越高。除了淀粉外,高粱果皮中单宁和籽粒中蛋白质、脂肪等,在发酵过程中会产生一些副产物,从而影响高粱酒的风味。本研究选了金选、两糯、兴湘、红梗和红糯等5个品种的高粱进行外观、生化性质等传统研究,结果表明两糯总淀粉及支链淀粉含量最高,金选单宁含量最高。为能分辨不同高粱品种,收集了5个不同品种的高粱作为实验样本,测定它们的近红外光谱,利用光谱特征对其进行定性定量分析,可快速鉴别出5种高粱之间的品种差异。利用高粱品种间SSR ...
