A unique case of dermatomyositis associated with anti-TIF1γ antibody and chondrosarcoma

Indirect immunofluorescent (IIF) assays have traditionally been used for the detection of antinuclear antibodies (ANA) in human serum. The presence of these antibodies can aid in the diagnosis of systemic autoimmune rheumatic diseases (SARD). This protocol demonstrates how to effectively perform the IIF technique to accurately detect these...

Magnetic bacteria exhibit a directed movement called magnetotaxis, driven by structures called magnetosomes. These magnetosomes consist of chains of magnetic particles made of either magnetite (Fe₃O₄) or greigite (Fe₃S₄) and are organized in a linear conformation by a protein scaffold within invaginations of the cell membrane. The bacteria align along the north–south magnetic field lines, much like a compass needle. They are typically microaerophilic or anaerobic...

This protocol includes dissection of murine long bones and bone marrow isolation, to generate bone marrow macrophages and produce osteoclasts using macrophage colony stimulating factor (M-CSF) and receptor activator of nuclear factor Kappa-B ligand (RANKL) or tumor necrosis factor alpha (TNF-α) and their arrest by anti-c-fms antibody, M-CSF...

This video demonstrates printed glycan array technology for analyzing circulating anti-glycan antibodies in mouse serum. The antibodies in the serum interact with specific glycans on the chip, which is confirmed by immunostaining followed by fluorescence...

Presented here is a protocol to use the CRISPR-Cas9 system for reducing the production of a protein in the adult honeybee brain to test antibody...

Consider a region consisting of several individual conductors with a definite charge density in the region between these conductors. The second uniqueness theorem states that if the total charge on each conductor and the charge density in the in-between region are known, then the electric field can be uniquely determined.
In contrast, consider that the electric field is non-unique and apply Gauss's law in divergence form in the region between the conductors and the integral form to the surface...
