Veterinary Dermatology, Volume 37, Issue 3, Page 353-364, June 2026.ABSTRACT Background Canine atopic dermatitis (cAD) is a multifactorial, inherited skin disease, estimated to affect ≤ 15% of dogs. Studies of skin messenger mRNA in cAD currently use invasive methods, including blood sampling and biopsy collection, whilst advances in human atopic dermatitis study methodology have demonstrated reliable use of minimally ...

ABCA12 Frameshift Deletion in Domestic Cats With Ichthyosis Fetalis
Veterinary Dermatology, Volume 37, Issue 3, Page 365-374, June 2026.ABSTRACT Background Ichthyosis fetalis (IF), also known as harlequin ichthyosis, is a rare and often fatal autosomal recessive congenital skin disorder. It is characterized by thickened, hard skin plaques and deep skin fissures that limit mobility and cause malformations of the eyes, lips and ears.

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Soft‐magnetic materials (SMMs) are indispensable for electrification and sustainable energy systems, yet their inherent mechanical fragility fundamentally limits applications under severe mechanical stresses. Enhancing the yield strength of SMMs is essential to prevent the degradation in magnetic performance and failure from plastic ...

转突变型A53Tα-突触核蛋白基因的帕金森模型小鼠中脑的全基因组甲基化测序分析 [PDF]
, 2020 【目的】研究帕金森氏病（PD）致病基因SNCA在A53T位置突变后对转基因小鼠中脑多巴胺，神经元DNA甲基化修饰的影响。【方法】分别取转突变的人源α-突触核蛋白（hα-syn）即hA53Tα-syn基因小鼠和对照组小鼠的中脑组织，采用重亚硫酸盐测序法（BS-seq）分别对12月龄的转基因小鼠和非转基因（nTg）小鼠进行全基因组甲基化分析，随后筛选出差异甲基化区域（DMR）用于GO富集分析。【结果】通过对比分析，我们总计发现481个DMR，其中高甲基化与低甲基化DMR分别有257和224个 ...

Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Wildlife reintroductions are socioecological processes entailing the intentional movement of organisms by people. In animal reintroductions, there is growing recognition of the importance of human dimensions and efforts to integrate these into reintroduction projects. To conceptually reframe reintroductions as processes of renewed coexistence (

SWEET1‐mediated glucose transport is crucial for energy availability in Arabidopsis
New Phytologist, Volume 249, Issue 4, Page 1816-1830, February 2026.Summary The stress‐responsive hormone abscisic acid (ABA) is known for its inhibitory effects on various physiological processes, including seed germination, often resulting in energy deprivation. Interestingly, ABA‐induced germination inhibition can be alleviated by exogenous glucose (Glc), mimicking a functional interplay between ABA and sugar ...
