Anatomic study of propeller flaps based on perforators of the posterior tibial artery.

Lower limb injuries resulting from sports activities, industrial accidents, and traffic incidents represent a significant global healthcare challenge. These injuries often entail a high risk of complications, especially when fractures are associated with substantial soft tissue damage. Open fractures classified as Gustilo type II or III are particularly susceptible to complications such as fistula and osteomyelitis.

Experimental and Theoretical Study on Electron Interactions with Acetic Acid Molecules.

The absolute total cross section for electron collisions with acetic acid has been measured using an electrostatic electron spectrometer and linear transmission method for collision energies ranging from 0.4 to 300 eV. Elastic electron scattering from acetic acid within a low-energy range has also been studied theoretically using the Schwinger multichannel and R-matrix methods, in the static-exchange and static-exchange plus polarization levels of approximation for energies up to 15 eV.

The human Dicer helicase domain is capable of ATP hydrolysis and single-stranded nucleic acid binding.

Background: Vertebrates have one Dicer ortholog that generates both microRNAs (miRNAs) and small interfering RNAs (siRNAs), in contrast to the multiple Dicer-like proteins found in flies and plants. Here, we focus on the functions of the human Dicer (hDicer) helicase domain. The helicase domain of hDicer is known to recognize pre-miRNA substrates through interactions with their apical loop regions.

Ontology-based integration and querying of heterogeneous rare disease data sources - POLVAS perspective.

The integration of rare disease medical databases belonging to different countries is an important problem, as a large number of observations are required for reliable statistical inference of patient data in order to facilitate clinical research. Such integration of national registry data, which requires harmonization of the heterogeneous data sets into a unified view, is facilitated in the European FAIRVASC project by developing a domain-specific ontology. The FAIRVASC project is dedicated to the rare disease of anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV).
