Morphophysiological dynamics of the proximal post‐testicular ducts in Crotalus durissus Linnaeus, 1758 (Squamata: Viperidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The organization and function of reptilian excurrent ducts remain poorly characterized, particularly in Neotropical snakes. We provide the first integrative morphological, histochemical, immunohistochemical, and ultrastructural analysis of the proximal post‐testicular ducts of Crotalus durissus across reproductive stages.

Histological Characterization and Comparative Transcriptomic Analysis of Gonads During Early Sex Differentiation in the Northern Snakehead (Channa argus)

open access: yesAnimal Research and One Health, EarlyView.
This study delineates the early sex differentiation timeline in the northern snakehead (Channa argus). These findings provide a foundation for future sex‐control breeding in this economically important species. ABSTRACT The northern snakehead (Channa argus) is an economically important aquaculture species in China.

HAND2 invades nucleolar condensates to pioneer lineage-specific cardiac pacemaker gene programs

open access: yesNature Communications
Although best known as the site for ribosome assembly, the nucleolus organizes heterochromatin into transcriptionally repressed Nucleolus-Associated Domains (NADs).

An Algorithm for the Nucleolus of Airport Profit Problems [PDF]

open access: yes
Airport profit games are a generalization of airport cost games as well as of bankruptcy games.In this paper we present a simple algorithm to compute the nucleolus of airport profit games.In addition we prove that there exists an unique consistent ...

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

open access: yesAnimal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

Protein‐Independent Liquid–Liquid Phase Separation of Adenosine Triphosphate Under Crowded Conditions

open access: yesChemistry – A European Journal, EarlyView.
ATP itself is able to undergo liquid–liquid phase separation in the presence of the macromolecular crowding agent PEG and physiological ATP concentrations are sufficient for phase separation in the presence of mM Mg2+ and crowders, mimicking intracellular conditions.

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

open access: yesDiagnostic 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.

The nucleolus [PDF]

open access: yes, 2009
The nucleolus is the most prominent subnuclear compartment in eukaryotic cells. It has a central function in the biogenesis of ribosomal subunits, but the past decade has revealed that a variety of additional non-ribosomal ribonucleoprotein (RNP ...

Diagnostic Usefulness of Cell Block Samples in Fluid Overload‐Associated Large B‐Cell Lymphoma

open access: yesDiagnostic Cytopathology, EarlyView.
ABSTRACT Fluid overload‐associated B‐cell lymphoma (FO‐LBCL) is a B‐cell neoplasm that presents as serous effusions without detectable tumor masses and Kaposi sarcoma‐associated herpesvirus (KSHV)/human herpesvirus 8 (HHV8) infection. Here, we report a case of an 81‐year‐old female patient with FO‐LBCL (Stage IVA) who presented with pericardial and ...

The functional organization of the nucleolus in proliferating plant cells.

open access: yesEuropean journal of histochemistry : EJH, 2001
The nucleolus is a prominent nuclear organelle which morphologically expresses all functional steps necessary for the synthesis of ribosomes, from transcription of rRNA genes to the assembly and maturation of preribosomal particles and their transport to the cytoplasm. Structurally, the nucleolus contains some basic components common to practically all
