Summary: This study investigated the nature of different types of stolons in Utricularia subgenus Polypompholyx through scanning electron microscopy, as well as statistically analyzed the correlations between stolon types and other traits across 56 species. The results showed that stolon types were taxonomically relevant and correlated to the distribution/climate, and they diverged with speciation events in Australia. Additionally, the study found that seedlings of Genlisea and Polypompholyx exhibited similar developmental patterns.

Summary: Sheltered preservation is a known phenomenon where organisms are trapped within cephalopod shells, providing important paleontological data. This study reports the discovery of the first crinoid preserved inside an early Albian ammonite in Madagascar. The crinoid belongs to the phyllocrinid family and represents the first finding of this family from Africa and the second from the southern margin of the Tethys. This finding highlights the potential use of ammonite shells for studying echinoderms.

Summary: The aim of this study was to investigate the immunocytochemistry of bifid trichomes in Aldrovanda vesiculosa and compare them with digestive trichomes. Light and electron microscopy revealed the structure of these trichomes, while fluorescence microscopy showed the localization of carbohydrate epitopes. The presence of endodermal cells and transfer cells, as well as the enrichment of arabinogalactan proteins in the cell walls, indicate the active and important role of bifid trichomes in plant function, particularly in solute transport.

Summary: The study investigated the relationship between the distribution and diversity of trichomes and pollinator syndromes in Central American and Mexican Pinguicula species. It was found that species pollinated by butterflies and hummingbirds had low diversity of non-glandular trichomes mainly found in the tube and basal part of the spur. In contrast, species pollinated by flies and bees showed a high variety of non-glandular trichomes, mainly found on the surface of corolla petals and at the entrance to the spur.

Summary: This study evaluated the expression of the TSG-6 gene in MSCs derived from the umbilical cord and assessed the expression of pro-inflammatory ILs. The results showed that the expression of the TSG-6 gene in MSCs was influenced by coexisting diseases and biochemical parameters of umbilical cord blood, including cord blood pH.

Summary: The study reports a diverse micro- and macrofauna, including crinoids, from the Lower Jurassic formations in Northwest Algeria. The discovery of Percevalicrinus in these formations represents its oldest record and the second one from the southern Tethyan margin. The morphology of Percevalicrinus suggests it is more closely related to Isocrininae rather than Balanocrininae. The assemblage and associated facies indicate a low-energy deep outer shelf/ramp setting.

Summary: This study evaluated the expression of VEGF family genes in cells from Wharton's jelly under various clinical conditions and found significant differences in gene expression depending on the clinical factors related to the course of pregnancy and childbirth.

Summary: Chronic venous disease (CVD) affects up to 30% of the global population and is characterized by disturbances in the microcirculation of veins. Diosmin, a phlebotropic drug, has been used in the treatment of CVD, but its molecular mechanism of action is not fully understood. In this study, patients were administered diosmin and biochemical assays were used to evaluate its effects on oxygen management, angiogenesis, and inflammation. The findings suggest that diosmin may regulate angiogenesis, inflammation, and hypoxia-inducible factor pathway in CVD.

Summary: Carnivorous plant Drosophyllum lusitanicum has two types of glands on its leaves, stalked mucilage glands and sessile digestive glands. The mucilage glands play a crucial role in prey lure and trapping, as well as survival in arid conditions. Investigating the cell wall composition, it was found that different cell types in the glands have distinct cell wall components.

Summary: In this study, a new species of turtle blood-feeding leech, Placobdella nabeulensis sp. nov., was discovered in Palearctic North Africa (Tunisia and Algeria). Detailed morphological analyses using light and scanning electron microscopes were conducted to describe this new species. Molecular data was used to distinguish this species from other members of the genus, and four DNA fragments were successfully amplified.

Summary: This study revisits the rare Middle Jurassic ammonite Oecoptychius refractus and finds its main occurrence in the Callovian Kosmoceras Zone and Quenstedtoceras Zone, with large morphological variation in body-chamber shape. The fossil record of O. refractus is better documented in the western Tethys (Poland, Germany, and France) compared to the eastern Tethys (Madagascar and India). The extensive palaeobiogeographic range of O. refractus may be influenced by recurrent sea level rises in the Middle Jurassic.

Summary: Vascular diseases are leading causes of death and morbidity, and there is a need for new biomarkers for monitoring and potential treatment. Next-generation sequencing of mRNA revealed significant differences in the expression of DNA repair-related genes in abdominal aortic aneurysm, chronic venous disease, and lower extremity artery disease, which could be utilized for the design of new biomarkers or therapies associated with these diseases.
