Holographic Chern-Simons Defects

We study SU(N) Yang-Mills-Chern-Simons theory in the presence of defects that shift the Chern-Simons level from a holographic point of view by embedding the system in string theory. The model is a D3-D7 system in Type IIB string theory, whose gravity dual is given by the AdS soliton background with probe D7-branes attaching to the AdS boundary along the defects. We holographically renormalize the free energy of the defect system with sources, from which we obtain the correlation functions for certain operators naturally associated to these defects. We find interesting phase transitions when the separation of the defects as well as the temperature are varied. We also discuss some implications for the Fractional Quantum Hall Effect and for two-dimensional QCD.Comment: 56 pages, 19 figures, v2: sign convention for CS level in terms of number of D7 branes switched, UV behavior of one and two point functions added in sec. 5.4.1 and 5.4.3, references added, typos correcte

Myofibroblasts proliferation of idiopathic and collagen vascular disorders associated nonspecific interstitial pneumonia.

Nonspecific interstitial pneumonia (NSIP) has been recognized as a separate histological classification of interstitial lung disease. Similar features are found not only in idiopathic NSIP, but also in NSIP associated with collagen vascular disorder (CVD-NSIP). We examined the clinical symptoms, laboratory findings, and prognosis of 13 cases of idiopathic NSIP and 11 cases of CVD-NSIP. Immunohistochemical staining was performed using the streptavidin/biotin/peroxidase method with anti-alpha-smooth muscle actin antibody. No differences in the distribution of clinical features, laboratory findings, and prognosis were observed between idiopathic NSIP and CVD-NSIP. In immunohistochemical staining of the fibrosing areas, myofibroblasts were observed in 7 of 13 idiopathic NSIP cases, but in 10 of 11 CVD-NSIP cases. With regards to intra-alveolar organization, myofibroblasts were observed in all 10 CVD-NSIP cases, but they were observed in only 2 of 9 idiopathic NSIP cases. We found a significantly higher myofibroblast proliferation in the intra-alveolar organization of CVD-NSIP compared to idiopathic NSIP. Clinically, idiopathic NSIP and CVD-NSIP are similar, but are pathologically different.</p

Signal amplification in electrochemical detection of buckwheat allergenic protein using field effect transistor biosensor by introduction of anionic surfactant

AbstractFood allergens, especially buckwheat proteins, sometimes induce anaphylactic shock in patients after ingestion. Development of a simple and rapid screening method based on a field effect transistor (FET) biosensor for food allergens in food facilities or products is in demand. In this study, we achieved the FET detection of a buckwheat allergenic protein (BWp16), which is not charged enough to be electrically detected by FET biosensors, by introducing additional negative charges from anionic surfactants to the target proteins. A change in the FET characteristics reflecting surface potential caused by the adsorption of target charged proteins was observed when the target sample was coupled with the anionic surfactant (sodium dodecyl sulfate; SDS), while no significant response was detected without any surfactant treatment. It was suggested that the surfactant conjugated with the protein could be useful for the charge amplification of the target proteins. The surface plasmon resonance analysis revealed that the SDS-coupled proteins were successfully captured by the receptors immobilized on the sensing surface. Additionally, we obtained the FET responses at various concentrations of BWp16 ranging from 1ng/mL to 10μg/mL. These results suggest that a signal amplification method for FET biosensing is useful for allergen detection in the food industry

BioGlue® coronary embolism during open heart surgery

AbstractIn cases of iatrogenic coronary embolism during cardiac surgery or percutaneous coronary intervention, small air bubbles or foreign bodies are directly injected, which usually result in serious adverse events if not treated promptly. We herein describe the case of a patient who developed acute myocardial infarction resulting in shock due to BioGlue® (CryoLife, Atlanta, GA, USA)-induced coronary embolism during the surgical repair of aortic dissection and was treated for retrieval of the material using a thrombectomy catheter.<Learning objective: Coronary embolism caused by surgical adhesives is a rare but potentially life-threatening complication. It is important for surgeons to promptly recognize and treat this serious condition in consultation with cardiologists.

Indication for Endoscopic Resection of Submucosal Colorectal Carcinoma: Special Reference to Lymph Node Metastasis

We investigated the relationship between histological factors and lymph node metastasis in 77 lesions with submucosally invasive colorectal carcinomas to establish useful criteria for lesions in which endoscopic treatment alone results in cure of malignancy. There were positive correlations between histological factors, including the level of invasion, the histologic grade, presence or absence of lymphatic invasion, presence or absence of budding, and lymph node metastasis (p < 0.05, p < 0.05, p < 0.005, p < 0.01). The presence or absence of venous invasion did not influence lymph node metastasis. Laparoscopic surgery involving lymph node dissection should be indicated for sm1 carcinoma lesions with unfavorable histological factors. In lesions diagnosed as sm2 or sm3 prior to resection, intestinal resection involving lymph node dissection by laparoscopic surgery should be directly performed without endoscopic resection

A study on intraalveolar exudates in acute mycoplasma pneumoniae infection.

Pathologic features of Mycoplasma pneumoniae infection (M. pneumonia) are generally non-specific, and the literature regarding the pathologic features of M. pneumonia with intraalveolar exudates is limited. Clinical and histopathological studies were performed in 3 patients with M. pneumonia which did not respond to erythromycin and minocycline, but all rapidly recovered after corticosteroid therapy. In pathologic findings, we observed intraalveolar exudates and focal organization in M. pneumonia, and its intraalveolar lesions were compared between M. pneumonia and bronchiolitis obliterans organizing pneumonia containing fibrin (BOOP). Immunohistochemical studies were performed using the streptavidin biotin peroxidase complex method with anti-alpha-smooth muscle actin antibody and anti-pancytokeratin AE1/AE3 antibody. In pathologic findings, more fibrin deposits in intaalveolar lesions were observed in M. pneumonia than in BOOP. In intaalveolar lesions of M. pneumonia, a larger amount of nuclear debris, more neutrophils, and more erythrocytes were noted. Myofibroblasts were observed in the organization of BOOP, while in the intaalveolar lesions of M. pneumonia, myofibroblasts were not observed. These results suggest that M. pneumonia with intraalveolar exudates responds well to corticosteroid and its intraalveolar lesions apparently differed from those in BOOP.</p
