Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

Cytoskeleton, EarlyView.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Challenges and Pitfalls to Diagnosing NUTM1‐Rearranged Neoplasia of the Pancreas by Cytology and Ancillary Studies

Diagnostic Cytopathology, EarlyView.
ABSTRACT Fine‐needle aspiration cytology specimens are frequently utilized for ancillary studies to identify diagnostic and prognostic information. This case highlights diagnostic pitfalls and challenges in diagnosing NUTM1‐rearranged neoplasia on pancreatic cytology.

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

Developmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Whole tissue imaging of cellular boundaries at sub‐micron resolutions for deep learning cell segmentation: Applications in the analysis of epithelial bending of ectoderm

Developmental Dynamics, EarlyView.
Abstract Background To understand cellular morphology, biologists have relied on traditional optical microscopy of tissues combined with tissue clearing protocols to image structures deep within tissues. Unfortunately, these protocols often struggle to retain cell boundary markers, especially at high enough resolutions necessary for precise cell ...

Study of germ cell tumors of ovary and associated immunohistochemistry [PDF]

Journal of Clinical and Basic Research
Background: Females have a 6–7% lifetime risk of developing ovarian tumors. Ovarian cancer is often termed a “silent killer” due to its frequent diagnosis at advanced stages.

Single‐cell sequencing reveals potential novel insights into appendage‐patterning and joint‐development in a spider

Developmental Dynamics, EarlyView.
Abstract Background Jointed appendages represent one of the key innovations of arthropods, and thus understanding the development and evolution of these structures is important for the understanding of the evolutionary success of Arthropoda. In this paper, we analyze a cell cluster that was identified in a previous single‐cell sequencing (SCS ...

Malignant Mixed Germ Cell Tumor in a Patient with Swyer Syndrome: A Case Report

JK Science
Mixed germ cell tumors are extremely rare tumors, usually malignant with a poor prognosis and made up of at least two different germ cell tumors. These tumors occur most often in the gonads but may also occur at other sites in body.

The role of Rho GTPases in facial morphogenesis

Developmental Dynamics, EarlyView.
The role of small GTPases, RHOA, RAC1, and CDC42 and pathway mediators is reviewed in the context of embryonic facial development. Lip fusion requires cytoskeletal remodeling during morphogenesis of the facial processes and during lip fusion.
