Astral Microtubules Are Dispensable for Pavarotti Localization During Drosophila Spermatogonial Mitoses.
Cytoskeleton (Hoboken)
January 2025
Department of Life Sciences, University of Siena, Siena, Italy.
We analysed here the dynamic of the kinesin-like Pavarotti (Pav) during male gametogenesis of wild-type and Sas4 mutant flies. Pav localizes to the equatorial region and the inner central spindle of late anaphase wild-type spermatogonia and displays a strong concentration at the midbody during late telophase. At metaphase of the first meiotic division, Pav shows widespread localization on the equatorial region of the spermatocytes.

Article Synopsis
- Ferritin-based hybrids are large macromolecules with potential uses in drug delivery and vaccines, but their design is complicated.
- Researchers designed hybrids using ferritin from Helicobacter pylori and a Small Ubiquitin-like Modifier, discovering that their assembly was influenced by varying preparation methods.
- They developed a quantitative model to analyze how different stoichiometries affected the structure of these hybrids, revealing unexpected patterns and establishing a framework for better design of ferritin-based systems.
Abdominal lymphangioleiomyomatosis in a man presenting with gastrointestinal hemorrhage as the first manifestation: a case report.

Department of Gastroenterology, The First Affiliated Hospital of Dali University, Dali, Yunnan, China.
Lymphangioleiomyomatosis (LAM) is a rare, low-grade malignant condition that typically affects women of childbearing age and primarily involves the lungs. While cases involving males and affecting the gastrointestinal tract are exceedingly uncommon. This report discusses an unusual case of abdominal LAM in a male patient with gastrointestinal hemorrhage.

Neurology, Dalhousie University, Halifax, CAN.
This case report discusses a unique presentation of an artery of Percheron (AOP) infarct resulting in rapidly resolving internuclear ophthalmoplegia (INO) without classical signs. This is the case of a 70-year-old male patient who presented to a community Emergency Department following acute code stroke activation. Physical exam and imaging studies including non-contrast CT, CT angiography, CT perfusion, and MRI were performed.

Thermosensitive liposomes (TSLs) have great potential for the selective delivery of cytostatic drugs to the tumor site with greatly reduced side effects. Here we report the discovery and characterization of new thermosensitive small multilamellar lipid nanoparticles (tSMLPs) with unusually high temperature selectivity. Furthermore, the temperature-dependent release of the fluorescent marker calcein from tSMLPs is enhanced by human serum albumin.
