Intra-arterial injection of particulate corticosteroids: mechanism of injury.

Mechanism of neurologic complications after epidural spinal injections (ESI) of particulate steroids at the cervical spine include intrathecal injection, epidural hematoma, direct spinal cord injury, and brain stem or cord infarction due to an arterial spasm or inadvertent intra-arterial injection of particulate steroids. At the lumbar spine, there is evidence that a spinal cord infarction secondary to an inadvertent intra-arterial injection of particulate steroids through a transforaminal approach is the leading mechanism.Variations in the arterial supply of the spinal cord help to understand how a lumbar ESI may lead to a spinal cord infarction at the thoracic level.

Targeted anticancer prodrug therapy using dextran mediated enzyme-antibody conjugate and β-cyclodextrin-curcumin inclusion complex.

A targeted and controlled drug delivery system based on β-cyclodextrin (β-CD) for encapsulation and controlled release of hydrophobic drugs in the presence of maltogenic amylase (MAase), as a cyclodextrin-hydrolyzing enzyme, and trastuzumab antibody has been developed. In this study, the inclusion complex of curcumin (CUR), as a model anticancer compound, with β-CD was prepared and we constructed an antibody-enzyme bioconjugate (dextran mediated MAase-Trastuzumab bioconjugate) for controlled and targeted release of CUR at HER2 positive cancer cells (including SKBR3 and BT474). Immunocytochemistry analysis indicated that the MAase-Trastuzumab bioconjugate had significant binding affinities to HER2 positive cancer cells and demonstrated high enzyme activity to degrade β-CD in order to rapid release of CUR on targeted cell surface.

Differentiation of cancer cells upregulates HLA‑G and PD‑L1.

A tumor contains special types of cells that have characteristics similar to stem cells that aid in tumor initiation, evasion and proliferation and are often resistant to chemotherapy. These cancer stem cells can be differentiated to eradicate their stemness and proliferative capacity by differentiating agents. This study investigated the effect of differentiation on the expression of two immune checkpoint inhibitors, human leukocyte antigen‑G (HLA‑G) and programmed death ligand‑1 (PD‑L1).

Fibrinogen αC domain: Its importance in physiopathology.

Abstract: Fibrinogen, involved in coagulation, is a soluble protein composed of two sets of disulfide-bridged Aα, Bβ, and γ-chains. In this review, we present the clinical implications of the αC domain of the molecule in Alzheimer's disease, hereditary renal amyloidosis and a number of thrombotic and hemorrhagic disorders. In Alzheimer's disease, amyloid beta peptide (Aβ) is increased and binds to the αC domain of normal fibrinogen, triggering increased fibrin(ogen) deposition in patients' brain parenchyma.
