New insights into the putative XX/XY sex chromosomal system in blue‐eyed red‐fin pleco Hypostomus soniae (Siluriformes, Loricariidae)

Journal of Fish Biology, EarlyView.
Abstract Blue‐eyed red‐fin pleco Hypostomus soniae (family Loricariidae) presented a putative sex system XX/XY in early stage. Aiming to explore the inter‐populational karyotypic variation and proposed emergence of the XX/XY system, we studied 13 H. soniae individuals (6 males, 7 females) from the Tapajós River.

Imaging malaria parasites across scales and time

Journal of Microscopy, EarlyView.
Abstract The idea that disease is caused at the cellular level is so fundamental to us that we might forget the critical role microscopy played in generating and developing this insight. Visually identifying diseased or infected cells lays the foundation for any effort to curb human pathology.

Predicting Malignant Transformation in Oral Leukoplakia: A Multilayer Perceptron Approach Incorporating Clinicopathological Features and DNA Content

Journal of Oral Pathology &Medicine, EarlyView.
ABSTRACT Background Oral leukoplakia (OL) is a potentially malignant disorder of the oral mucosa. Accurate prediction of malignant transformation (MT) remains a clinical challenge. This study aimed to develop and evaluate a machine learning model that integrates histopathological, demographic, and DNA content features to predict MT risk in OL.

Localising enzymes to biomolecular condensates increases their accumulation and benefits engineered metabolic pathway performance in Nicotiana benthamiana

Plant Biotechnology Journal, EarlyView.
Summary The establishment of Nicotiana benthamiana as a robust biofactory is complicated by issues such as product toxicity and proteolytic degradation of target proteins/introduced enzymes. Here we investigate whether biomolecular condensates can be used to address these problems. We engineered biomolecular condensates in N.

Prognostic Value of a Histopathological Scoring System and the Ki67 Proliferation Index in Dogs With Phaeochromocytoma

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT Canine phaeochromocytomas (PCCs) are neuroendocrine tumours with malignant potential. Metastatic disease remains the sole definitive evidence of malignancy. Histopathological criteria to predict long‐term survival have not been established in dogs.

A Novel Cell‐Penetrating Lipopeptide for DNA Binding, Self‐Assembly, and Delivery Into HeLa and Pluripotent Stem Cells

Journal of Peptide Science, Volume 32, Issue 3, March 2026.
A lipopeptide is designed that contains an epitope from simian virus T‐antigen (SV40T, PKKKRKV) conjugated to an N‐terminal palmitoyl (C16‐) moiety, which acts as a cell‐penetrating lipopeptide, with additional aggregation propensity conferred by the lipid chain. The lipopeptide enables DNA delivery into the cytoplasm and nucleus.
