Hematological Markers to Predict Enterectomy Versus Enterotomy in Dogs with Foreign-Body Intestinal Obstruction: Preliminary Data.

Intestinal obstruction caused by a foreign body accounts for 80% of all canine intestinal blockages [...

Ubiquitin-like modifier-activating enzyme 1 interacts with Zika virus NS5 and promotes viral replication in the infected cell.

Translation errors, impaired folding or environmental stressors (e.g. infection) can all lead to an increase in the presence of misfolded proteins.

TOR Inhibition Enhances Autophagic Flux and Immune Response in Tomato Plants Against PSTVd Infection.

Viroids are small, non-coding RNA pathogens known for their ability to cause severe plant diseases. Despite their simple structure, viroids like Potato Spindle Tuber Viroid (PSTVd) can interfere with plant cellular processes, including transcriptional and post-transcriptional mechanisms, impacting plant growth and yield. In this study, we have investigated the role of the Target Of Rapamycin (TOR) signaling pathway in modulating viroid pathogenesis in tomato plants infected with PSTVd.

Improving the diffraction quality of heat-shock protein 47 crystals.

Heat-shock protein 47 (HSP47) is a potential target for inhibitors that ameliorate fibrosis by reducing collagen assembly. In an effort to develop a structure-based drug-design system, it was not possible to replicate a previous literature result (PDB entry 4au4) for apo dog HSP47; instead, crystal forms were obtained in which pairs of dog HSP47 molecules interacted through a noncleavable C-terminal His-tag to build up tetramers, all of which had multiple molecules of HSP47 in the asymmetric unit and none of which diffracted as well as the literature precedent. To overcome these difficulties, a two-pronged approach was followed: (i) the His-tag was moved from the C-terminus to the N-terminus and was made cleavable, and (ii) Adnectin (derived from the tenth domain of human fibronectin type III) crystallization chaperones were developed.

Pulsed MPI Relaxometry of Brownian and Néel Field-Dependent Relaxation in Superparamagnetic Magnetite Nanoparticles Confirm Theory and Simulations.

Superparamagnetic iron oxide nanoparticles (SPIOs) are used as tracers in Magnetic Particle Imaging (MPI). It is crucial to understand the magnetic properties of SPIOs for optimizing MPI imaging contrast, resolution, and sensitivity. Brownian and Néel relaxation theory developed in the early 1950s posits that relaxation times can vary with particle size, shell thickness, medium viscosity, and the applied field strength.
