Phosphatidylinositol-3-kinase gamma (PI3Kγ) is a leukocyte-specific lipid kinase with signaling function downstream of G protein-coupled receptors to regulate cell trafficking, but its role in T cells remains unclear. To investigate the requirement of PI3Kγ kinase activity in T-cell function, we studied T cells from PI3Kγ kinase-dead knock-in (PI3Kγ(KD/KD)) mice expressing the kinase-inactive P...

Abdominal aortic aneurysms (AAA) are characterized by disruption and degradation of the elastic media, yet the elastolytic proteinases involved and their cellular sources are undefined. We examined if 92-kD gelatinase, an elastolytic matrix metalloproteinase, participates in the pathobiology of AAA. Gelatin zymography of conditioned medium from normal, atheroocclusive disease (AOD), or AAA tiss...

Cereal storage proteins are major nitrogen sources for humans and livestock. Prolamins are the most abundant storage protein in most cereals. They are deposited into protein bodies (PBs) in seed endosperm. The inner structure and the storage mechanism for prolamin PBs is poorly understood. Maize opaque10 (o10) is a classic opaque endosperm mutant with misshapen PBs. Through positional cloning, ...

The M line, which transverses the center of the thick filament region of skeletal muscle sarcomeres, appears to be a complex array of multiple structural elements. To date, two proteins have definitely been shown to be associated with the M line. They are MM-CK, localized in the M 4,4' substriations, and a 165,000-dalton (164 kd) protein, referred to as both M-protein and myomesin. Here we repo...

PURPOSE Kawasaki disease (KD) is a systemic vasculitis and affects many organ systems. It often presents sterile pyuria, microscopic hematuria, and proteinuria due to renal involvement. The aims of this study were to define clinical characteristics of acute KD patients with pyuria and to analyze meaning of pyuria in KD. METHODS The medical records and laboratory findings including serum and u...

SH2-containing Inositol Phosphatase (SHIP) is a 145 kD protein expressed in hematopoietic cells. SHIP is phosphorylated on tyrosine after receptor binding by several cytokines and has a negative role in hematopoiesis. We cloned a murine complementary DNA (cDNA) sequence for an isoform of SHIP with an internal 183 nucleotide deletion, encoding a protein 61 amino acids shorter than 145 kD SHIP. T...

BACKGROUND Kawasaki disease (KD) causes coronary artery disease (CAD) in children. In addition, a history of KD is suspected to be a risk factor for the development of atherosclerotic heart disease in the future. Histological senescence changes are a common denominator in atherosclerotic lesions in adults, so the present study investigated whether histological senescence changes had already occ...

Knowledge distillation (KD) is a method in which teacher network guides the learning of student network, thereby resulting an improvement performance network. Recent research this area has concentrated on developing effective definitions knowledge and efficient methods transfer while ignoring ability To fully utilize potential improve efficiency, study proposes multiple-stage KD (MSKD) that all...

In order to identify the inner ear autoantibodies, sera of 195 patients with sensorineural hearing loss and/or vertigo were reached with bovine inner ear antigen by western blotting method. Positive reaction was seen at several molecular weights, in which 33-35 kD, 42 kD and 68 kD were highly reactive. In moderate to severe hearing loss patients, positive reactions with 33-35 kD, 42 kD, 68 kD a...
