Magnetite nanoclusters (MNCs) were aligned one-dimensionally in the hollow cavity of a lipid nanotube (LNT) as a peapod using a simple mixing method in an aqueous solution. The electrostatic interaction of the two materials was considerable enough to allow the preparation of a densely packed MNC-LNT peapod composite. The composite ...

Complement is an important part of the immune system. It is initiated through three different pathways known as the classical, lectin and alternative pathway. The multi-molecular C1 complex of the classical pathway consists of a subcomponent, C1q, which binds to a tetramer comprising two C1r and two C1s proteases. A ...

Enhanced recovery after surgery (ERAS) programs have been shown to minimise morbidity in other types of surgery, but comparatively less data exist investigating ERAS in bariatric surgery. This article reviews the existing literature to identify interventions which may be included in an ERAS program for bariatric surgery. A narrative literature ...

This scanning electron microscopy image (∼2 μm wide) depicts high-aspect-ratio features patterned in silicon using sequential infiltration synthesis (SIS) enhancement of photoresist. SIS penetrates the polymeric resist layer with etch-resistant alumina, thereby transforming it into a hard mask. This conversion enables the use of very thin resist layers, so pattern ...

Sialyldisaccharides are significant terminal components of glycoconjugates and their negative charge and conformation are extensively utilized in molecular recognition processes. The conformation and flexibility of four biologically important sialyldisaccharides [Neu5Acα(2-3)Gal, Neu5Acα(2-6)Gal, Neu5Acα(2-8)Neu5Ac and Neu5Acα(2-9)Neu5Ac] are studied using Molecular Dynamics simulations of 20 ns duration to deduce the conformational preferences of the ...

Ankylosing spondylitis (AS), psoriasis and inflammatory bowel disease (IBD) often coexist in the same patient and in their families. In AS, genes within the MHC region, in particular HLA-B27, account for nearly 25% of disease hereditability, with additional small contributions from genes outside of the MHC locus, including those involved ...

The first Mannich reaction employing phthalides using a quinidine-based multifunctional catalyst has been developed. The reported method led to the synthesis of 3,3-disubstituted phthalide derivatives in excellent yields, with good diastereo- and enantioselectivities. Convenient synthesis of chiral isoquinolinones and isoquinolines has also been demonstrated.

BACKGROUND: Survival rates after resection of pancreatic adenocarcinoma are poor; however, several tumor-related prognostic factors have been identified. There is increasing evidence that additional patient-related prognostic factors, such as ongoing systemic inflammatory response, are associated with poor outcomes in patients with common solid tumors. The purpose of this study was ...

During budding of yeast cells peroxisomes are distributed over mother cell and bud, a process that involves the myosin motor protein Myo2p and the peroxisomal membrane protein Inp2p. Here we show that Pex19p, a peroxin implicated in targeting and complex formation of peroxisomal membrane proteins, also plays a role in ...

Triterpene cyclases catalyze a broad range of cyclization reactions to form polycyclic triterpenes. Triterpene cyclases that convert squalene to hopene are named squalene-hopene cyclases (SHC) and triterpene cyclases that convert oxidosqualene are named oxidosqualene cyclases (OSC). Many sequences have been published, but there is only one structure available for each ...

Diabetes mellitus is associated with an increased risk of cardiovascular disease due to its negative impact on the vascular endothelium. The damaged endothelioma is repaired by resident cells also through the contribution of a population of circulating cells derived from bone marrow. These cells, termed endothelial progenitor cells (EPCs) are ...

As part of the cytoskeleton, actin is essential for the morphology, motility, and division of eukaryotic cells. Recent X-ray fiber diffraction studies have shown that the conformation of monomeric actin is flattened upon incorporation into the filament by a relative rotation of its two major domains. The antiproliferative activity of ...

Using proteomics combined with immunohistochemistry (IHC), we re-evaluated our previous hypothesis that voluntary eccentric exercise does not result in inflammation or necrosis while it does lead to muscular adaptation/remodeling through Z-band related proteins. Muscle biopsies from m. vastus lateralis were taken from five control and five exercised subjects 48 h after ...

A new multiferroic material, CuBr(2) , is reported for the first time. CuBr(2) has not only a high transition temperature (close to liquid nitrogen temperature) but also low dielectric loss and strong magnetoelectric coupling. These findings reveal the importance of anion effects, in the search for the high temperature multiferroics ...

Drinking water treatment typically uses strong oxidants such as chlorine which are capable of converting Cr(III) to Cr(VI). The rates and extent of Cr(III) oxidation by chlorine are not well established. Cr(III) oxidation experiments were therefore conducted in distilled deionized water and New York City tap water dosed initially with ...

RNA polymerases are enzymes that transcribe genes from DNA onto strands of RNA. The transcription elongation by multi-subunit RNA polymerases is processive but nonuniform: one enzyme can translocate along the DNA template for thousands of nucleotide addition steps but, sometimes, it can enter backtracking long pauses. Here, we present a ...
