一例孟加拉白虎幼崽猫细小病毒感染治疗

open access: yes野生动物学报, 2023
2021年9月,重庆市动物园1只3月龄孟加拉白虎(Panthera tigris tigris)出现呕吐、发烧、便血和精神沉郁等症状。经血细胞检测,发现该幼崽白细胞数量下降,通过实时定量PCR检测,最终确定为猫细小病毒(Feline parvovirus,FPV)感染。同圈舍另一只幼崽和母亲及周边圈舍3只华南虎(Panthera tigris amoyensis)检测结果均为猫细小病毒阳性,但未表现出临床症状。幼崽经过1周的抗体、干扰素等治疗,白细胞数量恢复正常,出血症状消失,但总蛋白仍较低 ...

Eutectic Topology Regulates Deformation Pathways Enabling Synergistic Superelasticity and Strength in EBF3‐Fabricated NiTiNb Alloys

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT The deformation behavior of NiTiNb shape memory alloys is governed by microstructural heterogeneity, specifically the interconnected topology of the β‐Nb phase. The regulatory role of the eutectic structure in load partitioning and the evolution of deformation mechanisms, particularly in high‐Nb systems, has not been clearly understood.

Colloid‐Mediated Surface Reconstruction Through High‐Valence Element Integration Enables Stabilized Oxygen Redox and Fast Interfacial Kinetics in Li‐Rich Cathodes

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Lithium‐rich manganese‐based cathodes (LRM) deliver high discharge capacities beyond 250 mAh g−1, but their practical deployment is restricted by irreversible oxygen redox, structural reconstruction, sluggish kinetics and unstable cathode‐electrolyte interfaces (CEI). Here, we develop a colloid‐assisted anchoring‐diffusion engineering strategy

Amino‐Functionalized Mesoporous SiO2 Hollow Nano‐Doughnuts for Enhanced Gas Adsorption and Specific Foodborne Pathogen Recognition in Point‐of‐Care Detection

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Developing rapid, precise gas sensors for Listeria monocytogenes (LM) biomarker detection faces challenges due to suboptimal gas‐solid interactions. Herein, we report the rational synthesis of amino‐functionalized mesoporous SiO2 hollow nano‐doughnuts (MS‐2‐NH2‐2) via modification with (3‐aminopropyl) trimethoxysilane (AAPTMS), which enables ...
