Cryoglobulinemia concurrent with Leishmania infantum infection in a dog and its interference with two automated hematology analyzers

Veterinary Clinical Pathology, Volume 54, Issue 1, Page 15-23, March 2025.
Abstract A 6‐year‐old, intact male English Bulldog presented for evaluation of weakness. Physical examination revealed mildly pale mucous membranes and ophthalmologic alterations. A complete blood cell count was performed on the Urit Smart V5 and the Sysmex XN‐1000V, and showed several hematologic discrepancies between the analyzers.

Scaffold hopping approaches for the exploration of herbicidally active compounds inhibiting Acyl‐ACP Thioesterase

Pest Management Science, Volume 81, Issue 5, Page 2617-2634, May 2025.
The work presented herein details the scaffold hopping efforts to find novel herbicidal lead structures that target acyl‐ACP thioesterase. This resulted in the discovery of the new dihydropyranopyridine structural class that exhibits good in vitro inhibition of acyl‐ACP coupled with strong herbicidal activity in greenhouse trials.

Nanoparticles Combining Host‐Directed Therapeutics and Antibiotics to Boost Bacterial Killing and Overall Survival of Zebrafish Embryos Infected with Mycobacterium Marinum

Advanced Therapeutics, Volume 8, Issue 4, April 2025.
This study investigates the combination of host‐directed therapeutics (HDT) with antibiotics in a single polymeric micelle based on polypept(o)ides for the therapy of Mycobacterium tuberculosis (Mtb) and ‐marinum (Mm) infections. When the HDT and antibiotic are co‐encapsulated, it significantly reduces bacterial burden in cells and improves overall ...

THEORETICAL AND CHEMOMETRIC STUDY OF SUBSTITUTED OXAZINES

Journal of the Chilean Chemical Society, 2005
The application of the Principal Component of Analysis (PCA) over the theoretical data of a series of substituted 1,3-oxazines helps to determine the factors that rule the conformational equilibrium. Repulsive and intertribal syn-1,3-diaxial interactions have been used as determiners for the axial structures, whereas dipolar interactions are preferred ...
