Kawasaki disease (KD) is an acute systemic vasculitis of childhood. The diagnosis is based on clinical criteria. However, the presentation of KD is incomplete/atypical for approximately 20 % of patients. Kawasaki disease is complicated with coronary artery lesions (CALs) and considered the most common cause of acquired heart disease in children. ...

BACKGROUND: For rectal cancer, an involved circumferential resection margin (CRM), defined as tumor cells within 1 mm of the CRM, is of established prognostic significance. This definition for the esophagus, however, is controversial, with the UK Royal College of Pathologists (RCP) recommending the 1 mm definition, while the College of American Pathologists ...

The first echinocandin-type antimycotic (echinocandin B) was discovered in the 1970s. It was followed by the isolation of more than 20 natural echinocandins. These cyclic lipo-hexapeptides are biosynthesized on non-ribosomal peptide synthase complexes by different ascomycota fungi. They have a unique mechanism of action; as non-competitive inhibitors of β-1,3-glucan synthase ...

Adenosine monophosphate-activated protein kinase (AMPK) is an evolutionarily conserved signaling molecule that is emerging as one of the most important energy sensors in the body. AMPK monitors cellular energy status and is activated via phosphorylation when energy stores are low. This allows for maintenance of energy homeostasis by promoting catabolic ...

Dielectrophoresis is a versatile tool for the sorting, immobilization and characterization of cells in microfluidic systems. The performance of dielectrophoretic (DEP) systems strongly relies on the configuration of microelectrodes, which produce a non-uniform electric field. However, once fabricated, the microelectrodes cannot be reconfigured to change the characteristics of the system. ...

The development of the endocrine pancreas is controlled by a hierarchical network of transcriptional regulators. It is increasingly evident that this requires a tightly interconnected epigenetic "programme" to drive endocrine cell differentiation and maintain islet function. Epigenetic regulators such as DNA and histone-modifying enzymes are now known to contribute to ...

The predatory Bacteriovorax are Gram-negative bacteria ubiquitous in saltwater systems that prey upon other Gram-negative bacteria in a similar manner to the related genus Bdellovibrio. Among the phylogenetically defined clusters of Bacteriovorax, cluster V has only been isolated from estuaries suggesting that it may be a distinct estuarine phylotype. To ...

Our previous clinical and basic studies have demonstrated that ginsenoside Rd (GS-Rd) has remarkable neuroprotective effects after cerebral ischemia but the underlying mechanisms are still unknown. In our latest studies, we revealed that GS-Rd could prevent mitochondrial release of apoptosis-inducing factor (AIF) and reduce inflammatory response following transient focal ischemia ...

The assembly of iron-sulfur clusters (ISCs) in eukaryotes involves the protein Frataxin. Deficits in this protein have been associated with iron inside the mitochondria and impair ISC biogenesis as it is postulated to act as the iron donor for ISCs assembly in this organelle. A pronounced lack of Frataxin causes ...

To examine the self-assembly of cationic-anionic (catanionic) surfactant mixtures, we performed molecular dynamical (MD) simulations at fixed surfactant numbers but different ratios of cationic cetyltrimethylammonium bromide (CTAB) and anionic sodium octyl sulfate (SOS) aqueous mixtures, which were investigated previously (J. Phys. Chem. 1996, 100, 5874-5879). The simulation results show that ...

Lyophilic but not sticky! A lyophilic yet nonwettable surface seems self-contradictory, however, a nanostructured super-lyorepellent surface is used to reveal that a lyophilic nonwettable state is theoretically feasible in an oil/water/air/solid four-phase system. This finding may throw light on multiphase interface behavior.
