Molecular Magnetic Resonance Imaging of Liver Fibrosis and Fibrogenesis Is Not Altered by Inflammation.

Methods: Three groups of mice that develop either mild type 2 inflammation and fibrosis (wild type), severe fibrosis with exacerbated type 2 inflammation (Il10-/-Il12b-/-Il13ra2-/-), or minimal fibrosis with marked type 1 inflammation (Il4ra∂/∂) after infection with S. mansoni were imaged using both probes for determination of signal enhancement. Schistosoma mansoni-infected wild-type mice developed chronic liver fibrosis.

Virtual screening of antibacterial compounds by similarity search of Enoyl-ACP reductase (FabI) inhibitors.

Antibiotic resistance is an alarming issue, as multidrug-resistant bacteria are growing worldwide, hence the decrease of therapeutic potential of available antibiotic arsenal. Among these bacteria, was pointed by the WHO in the pathogens list to be prioritized in drug development. We report the use of chemical similarity models for the virtual screening of new antibacterial with structural similarity to known inhibitors of FabI.

Peroxidase Sensitive Amplifiable Probe for Molecular Magnetic Resonance Imaging of Pulmonary Inflammation.

An amplifiable magnetic resonance imaging (MRI) probe that combines the stability of the macrocyclic Gd-DOTAGA core with a peroxidase-reactive 5-hydroxytryptamide (5-HT) moiety is reported. The incubation of the complex under enzymatic oxidative conditions led to a 1.7-fold increase in at 1.

Ga-NODAGA-Indole: An Allysine-Reactive Positron Emission Tomography Probe for Molecular Imaging of Pulmonary Fibrogenesis.

Oxidized collagen, wherein lysine residues are converted to the aldehyde allysine, is a universal feature of fibrogenesis, i.e. actively progressive fibrosis.

Encapsulation of trans-aconitic acid in mucoadhesive microspheres prolongs the anti-inflammatory effect in LPS-induced acute arthritis.

trans-Aconitic acid (TAA) is the main constituent of the leaves from the medicinal plant Echinodorus grandiflorus, used to treat different inflammatory diseases. TAA induces a potent but short-lasting biological response, credited to its high polarity and unfavorable pharmacokinetics. Here we developed, characterized and evaluated the anti-inflammatory activity of mucoadhesive microspheres loaded with TAA.

Evaluation of antitumor activity and cardiac toxicity of a bone-targeted ph-sensitive liposomal formulation in a bone metastasis tumor model in mice.

Chemotherapy for bone tumors is a major challenge because of the inability of therapeutics to penetrate dense bone mineral. We hypothesize that a nanostructured formulation with high affinity for bone could deliver drug to the tumor while minimizing off-target toxicity. Here, we evaluated the efficacy and toxicity of a novel bone-targeted, pH-sensitive liposomal formulation containing doxorubicin in an animal model of bone metastasis.

Development of imaging probes for bone cancer in animal models. A systematic review.

Bone is a dynamic tissue that is constantly remodeled throughout the lifetime to ensure the integrity of the skeleton. Primary cancer cells disseminate into circulation, often extravasating to bone, where they interact with the bone marrow to grow and proliferate, disrupting the bone homeostasis. Although primary bone tumors account for less than 0.
