Leukoencephalomacia due to ischemic vascular accident in a Tremarctos ornatus (Spectacled bear)

, 2023
Abstract Tremactor ornatus (Spectacled bear) are the only ursids natives of South America and are present in many Zoo collections. Neurologic diseases are not common in this species and brain injuries are linked mainly to viral diseases; however ischemic brain events are not commonly reported.

Ursodeoxycholic acid in the Ursidae: biliary bile acids of bears, pandas, and related carnivores.

Journal of Lipid Research, 1993
The biliary bile acid composition of gallbladder bile obtained from six species of bears (Ursidae), the Giant panda, the Red panda, and 11 related carnivores were determined by reversed phase liquid chromatography and gas chromatography-mass spectrometry.

Analysis of complete mitochondrial genome sequences increases phylogenetic resolution of bears (Ursidae), a mammalian family that experienced rapid speciation

BMC Evolutionary Biology, 2007
Background Despite the small number of ursid species, bear phylogeny has long been a focus of study due to their conservation value, as all bear genera have been classified as endangered at either the species or subspecies level.

Anesthetic protocol using propofol and isoflurane in spectacled bear (Tremarctos ornatus)

Brazilian Journal of Veterinary Research and Animal Science, 2023
The management of wild animals generally requires chemical containment with the use of sedatives, tranquilizers, general anesthetics or dissociative drugs. The spectacled bear (Tremarctos ornatus) is the only member of the family Ursidae characteristic of South America. There are few reports on the main anesthetic protocols used in this specie. The aim

Camera trap survey of medium and large mammals in a montane rainforest of northern Peru

Revista Peruana de Biología, 2011
Camera traps are a powerful tool for inventorying elusive and rare species and very useful to obtain ecologi- cal data for plans that involve wildlife conservation.

Targeting LDHA Palmitoylation Sensitizes GBM to Chemoradiotherapy via Suppressing Palmitic Acid Induced Glycolytic Reprogramming

Advanced Science, EarlyView.
Mesenchymal GSCs preferentially uptake palmitic acid, thereby promoting ZDHHC12‐mediated LDHA palmitoylation. This modification enhances LDHA enzymatic activity, drives glycolytic reprogramming, and facilitates exosomal LDHA‐mediated TAM regulation.

CXCL3 Antagonism Reverses Systemic Antitumor Immune Memory Impairment Associated With High Tumor Burden and Sensitizes Anti‐PD‐1 Therapy

Advanced Science, EarlyView.
This study reveals that large tumors secrete more chemokine CXCL3, which recruits immunosuppressive neutrophils to the periphery, thereby impairing the activation and memory of systemic tumor‑reactive CD8+ T cells. CXCL3 antagonism restores systemic immune memory and enhances the antitumor efficacy of anti‑PD‑1 therapy, offering a potential strategy to

Structural Control of Stromal‐Immune Coupling by COL24A1 Underlies Pregnancy Maintenance

Advanced Science, EarlyView.
COL24A1 emerges as a collagen‐associated regulator of maternal‐fetal interface homeostasis. Its deficiency promotes a maladaptive TIMP1‐high stromal state, impaired ECM turnover, collagen accumulation, and stromal–immune dysregulation, contributing to pregnancy loss.

Triggered Calcium Lightning Programs Cochlear Development

Exploration, EarlyView.
Summary: Before the onset of hearing, the developing inner ear generates spontaneous calcium signals that are thought to guide maturation. In this study, we discovered a rapid and widespread calcium flash—dubbed “Ca2+ lightning”—originating from supporting cells beneath the sensory hair cells, which triggers coordinated calcium waves across the entire ...
