Boron dipyrromethene (Bodipy) are known to be efficient photon harvesting chromophores. However, their study as active materials in bulk heterojunction (BHJ) solar cells is still scarce. In this paper, we developed new synthetic ways to design original Bodipy-based dumbbell-shape molecules, including a first 2,3,5,6-tetravinyl aromatic Bodipy molecule. We demonstrated that high fill factors can be obtained in BHJ solar cells when blended with a fullerene derivative, leading to a new Bodipy-based record power conversion efficiency of 5...

BACKGROUND: The objective of this study was to evaluate the coagulation profile by thromboelastography in morbidly obese patients who undergo bariatric surgery. Morbid obesity entails increased risk for thromboembolic events. There is no clear protocol for thromboembolic prophylaxis, regarding timing and length of treatment, in bariatric surgery. Thromboelastography provides data on a coagulation process from creation of the clot until the fibrinolysis. METHODS: Ninety-three morbidly obese patients were prospectively recruited within a 2-year period...

Cutaneous squamous cell carcinoma (cSCC) is one of the most common metastatic skin cancers with increasing incidence. We examined the roles of complement component C3 and complement factor B (CFB) in the growth of cSCC. Analysis of cSCC cell lines (n = 8) and normal human epidermal keratinocytes (n = 11) with real-time quantitative PCR and Western blotting revealed up-regulation of C3 and CFB expression in cSCC cells. Immunohistochemical staining revealed stronger tumor cell-specific labeling for C3 and CFB in invasive cSCCs (n = 71) and recessive dystrophic epidermolysis bullosa-associated cSCCs (n = 11) than in cSCC in situ (n = 69), actinic keratoses (n = 63), and normal skin (n = 5)...

INTRODUCTION: von Willebrand disease (VWD) is the most common inherited bleeding disorder. In VWD patients, large variations in bleeding tendency are observed, which cannot be completely explained by the variation in von Willebrand factor levels or activities. Thus, there must be additional factors, for instance, changes in fibrinolysis that have an effect on the variation in bleeding tendency in VWD patients. AIM: To investigate whether plasminogen activator inhibitor-1 (PAI-1) level influences the variation in bleeding tendency in VWD patients...

Dentinogenesis imperfecta is an phenotypic alteration in the formation of the organic matrix. It causes the rapid and progressive wear of tooth structure, which may compromise tooth function and aesthetics. This is a case of a 1y, 8m-old child with dentinogenesis imperfecta. All teeth presented with an opalescent appearance and grayish color hue. Compromised structural integrity was noted as excessive wear and fracturing of the enamel from the dentin layer. With low doses of midazolam (oral) and chloral hydrate (rectal) administration, in a hospital environment, sedation was used to aid full mouth rehabilitation...

Staphyloccus aureus is a major human pathogen leading frequently to sepsis and soft tissue infections with abscesses. Multiple virulence factors including several immune modulating molecules contribute to its survival in the host. When S. aureus invades the human body, one of the first line defenses is the complement system, which opsonizes the bacteria with C3b and attract neutrophils by release of chemotactic peptides. Neutrophils express Complement receptor-1 [CR1, CD35) that interacts with the C3b-opsonized particles and thereby plays an important role in pathogen recognition by phagocytic cells...

Previous studies have reported several cases of juvenile myelomonocytic leukemia (JMML) developing blastic transformation during an indolent clinical course, but the underlying mechanism of transformation is still not well understood. In this report, we describe a case of JMML with blastic transformation possibly caused by additional copy number gains of the KRAS mutant allele. We have discovered that the copy number gain of the mutant allele is an additional possible cause of blastic transformation in JMML...

Metabotropic glutamate receptors (mGluR) are predominantly involved in maintenance of cellular homeostasis of central nervous system. However, evidences have suggested other roles of mGluR in human tumors. Aberrant mGluR signaling has been shown to participate in transformation and maintenance of various cancer types, including malignant brain tumors. This review intends to summarize recent findings regarding the involvement of mGluR-mediated intracellular signaling pathways in progression, aggressiveness, and recurrence of malignant gliomas, mainly glioblastomas (GBM), highlighting the potential therapeutic applications of mGluR ligands...
