Anti-DNA antibodies cross-reactive with β-glycoprotein I induce monocyte tissue factor through the TLR9 pathway.

Antibodies specific for cardiolipin (CL)-β-glycoprotein I (βGPI) are known to induce tissue factor (TF) expression by monocytes and endothelial cells which leads to a prothrombotic state in antiphospholipid syndrome (APS), but the mechanism is not fully elucidated. Previously, we reported that the mouse monoclonal anti-CL-βGPI antibody WB-6 cross-reacts with DNA, enters monocytes binding to cell surface DNA, and induces TF expression. The current study aimed to identify the intracellular signaling pathways involved in this process.

β-Lactamase-non-producing ampicillin-resistant Haemophilus influenzae is acquiring multidrug resistance.

Background: Haemophilus influenzae strains with reduced susceptibilities to antimicrobial agents have emerged in Japan. Here, we aimed to investigate H. influenzae non-susceptibility to β-lactams and non-β-lactams.

Phosphorylation of the RSRSP stretch is critical for splicing regulation by RNA-Binding Motif Protein 20 (RBM20) through nuclear localization.

RBM20 is a major regulator of heart-specific alternative pre-mRNA splicing of TTN encoding a giant sarcomeric protein titin. Mutation in RBM20 is linked to autosomal-dominant familial dilated cardiomyopathy (DCM), yet most of the RBM20 missense mutations in familial and sporadic cases were mapped to an RSRSP stretch in an arginine/serine-rich region of which function remains unknown. In the present study, we identified an R634W missense mutation within the stretch and a G1031X nonsense mutation in cohorts of DCM patients.

Parastomal hernia repair with the Sugarbaker technique using e-PTFE mesh.

Purposes: Although surgery is commonly used to treat parastomal hernia, it is very difficult and has shown poor results. Recently, repair with prosthetic materials has been thought to be a more promising method.

Methods: The Sugarbaker technique with e-PTFE mesh (Dualmesh) performed via open surgery was adopted for seven patients with parastomal hernia.

Hyalinizing spindle cell tumor with giant rosettes of the omentum.

We report the first case of a hyalinizing spindle cell tumor with giant rosettes of the omentum. The mesenchymal tumor arises from a multiplication of fibroblastic cells containing large rosette-like structures composed of a central collagen core surrounded by plump oval to spindle tumor cells. A 38-year-old woman exhibited the symptom of abdominal pain in the right side, with a correlated sensation of a mass in the same area.
