Perivascular epithelioid cell (PEC) tumors (PEComas) are a family of related mesenchymal tumors composed of PECs which co-express melanocytic and smooth muscle markers. Although their distinctive histologic, immunohistochemical, ultrastructural, and genetic features have been clearly demonstrated, their histogenesis and normal counterpart remain largely unknown. Precursor lesions of PEComas hav...

BACKGROUND AND OBJECTIVES Enteral nutrition (EN) can improve clinical outcomes as an important treatment in critically ill patients. However, when patients suffer from gastrointestinal function disorders, intestinal intolerance occurs and EN administration may be delayed and even fails to perform. Pectin, a structural heteropolysaccharide, could protect gastrointestinal function from disorders ...

Utilizing photoelectrochemical (PEC) cells to directly collecting solar energy into chemical fuels (e.g., H2 via water splitting) is a promising way to tackle the energy challenge. α-Fe2O3 has emerged as a desirable photoanode material in a PEC cell due to its wide spectrum absorption range, chemical stability, and earth abundant component. However, the short excited state lifetime, poor minori...

It is different to detect defect in multilayer structure of an aging aircraft fuselage, pulsed eddy current (PEC) technique has been demonstrated to be capable of quantifying this defect. Based on theoretical analysis of PEC technique, the array probe is designed and the array PEC imaging technique has been supposed to detect corrosion in the multilayer structure. By selecting peak amplitude an...

Perspectives on primary eye care We think of primary eye care (PEC), and any kind of primary health care (PHC), as a 'frontline' activity, providing care and identifying disease before it becomes a serious medical issue. However, as this course showed, even a cursory review of systems across the world reveals that there is no common understanding of what primary eye care means and there exists ...

Arrays of ZnO nanorods (NRs) were successfully converted into nanotubes (NTs), used as photoelectrodes in photoelectrochemical (PEC) cells after their sensitization with CdSe quantum dots (QDs) and a strong correlation between the PEC performance and geometrical structure of ZnO NTs@CdSe(QDs) and ZnO NRs@CdSe(QDs) was established under the same conditions.

PURPOSE This study attempted to examine parental satisfaction with pediatric emergency care (PEC) in Korea and investigate the features influencing overall satisfaction. METHODS A nationwide, cross-sectional survey was conducted among parents who had taken their children to an Emergency Department (ED) in the three years prior to the study. A 21-item, structured questionnaire was administered...

Fas ligand (FasL) has the potential to induce inflammation accompanied by massive neutrophil infiltration. We previously reported that FasL rapidly induces the production of various inflammatory cytokines including IL-1beta and IL-17. In this study, we investigated the mechanism of the FasL-induced IL-17 production. We found that the culture supernatant of mouse resident peritoneal exudate cell...

Since its introduction as an alternative intestinal microbiota alteration approach, fecal microbiota transplantation (FMT) has been increasingly used as a treatment of choice for patients with ulcerative colitis (UC), but no reports exist regarding FMT via percutaneous endoscopic cecostomy (PEC). This report describes the case of a 24-year-old man with a 7-year history of recurrent, steroid-dep...
