Chemical dehydration‐induced ultrafast clearing method for human tissues

VIEW, EarlyView.
Three‐dimensional (3D) histology of human tissue through clearing has been hampered by the lengthy and intricate procedure. Here, a rapid and straightforward clearing protocol termed single‐step dehydration solvent‐based clearing (SSD) is proposed via a chemical dehydration strategy.

3D imaging of neuronal inclusions and protein aggregates in human neurodegeneration by multiscale x‐ray phase‐contrast tomography

Brain Pathology, EarlyView.
x‐ray phase‐contrast tomography enabled three‐dimensional, label‐free visualization and quantification of protein aggregates in neurodegenerative diseases with isotropic submicrometer resolution. The study revealed distinct electron density patterns in Lewy bodies, Hirano bodies, granulovacuolar degeneration, and amyloid plaques, highlighting their ...

Compartmentalisation in cAMP signalling: A phase separation perspective

British Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

Comparative cytogenetics of some marsupial species (Didelphimorphia, Didelphidae) from the Amazon basin

Comparative Cytogenetics, 2017
We investigated the karyotype of 18 didelphid species captured at 13 localities in the Brazilian Amazon, after conventional staining, C-banding, Ag-NOR and fluorescent in situ hybridization (FISH) using the 18S rDNA probe.

Liquid–Liquid Phase Separation in Major Hallmarks of Cancer

Cell Proliferation, EarlyView.
Aberrant condensates formed through phase separation are involved in the dysregulation of various critical cellular processes, including genome stability, transcriptional regulation and signal transduction, thereby promoting malignant transformation and the acquisition of multiple cancer hallmarks.

Atypical Fibroxanthoma/Pleomorphic Dermal Sarcoma With Osseous Metaplasia: A Series of Three Cases

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Atypical fibroxanthoma (AFX) and pleomorphic dermal sarcoma (PDS) are rare mesenchymal tumors typically arising on sun‐damaged skin of the head and neck in elderly patients. PDS is a more aggressive tumor but with similar demographics, cellular morphology, immunohistochemical features, and genetic findings.

Primary cardiac T‐cell rich large B‐cell lymphoma causing aortic stenosis with metastasis in a Warmblood

Equine Veterinary Education, EarlyView.
Summary An 18‐year‐old Warmblood mare was presented to the Royal Veterinary College Equine Referral Hospital for investigation of progressive periocular and facial swelling, weight loss and tachycardia. Physical examination additionally identified bilateral pansystolic (grade 5/6 basilar left‐sided, 2/6 right‐sided), cardiac murmurs, submandibular ...

Comparative cytogenetic studies of Bufo ictericus, B. paracnemis (Amphibia, Anura) and an intermediate form in sympatry

Genetics and Molecular Biology, 2003
Specimens of Bufo ictericus, Bufo paracnemis and a third type, considered an intermediate subgroup between these species, were cytogenetically studied by conventional Giemsa staining, C-banding and staining of the nucleolus organizer region (NOR).
