The sphingomyelin-derived messenger ceramides provoke neuronal apoptosis through caspase-3 activation, while the neuropeptide pituitary adenylate cyclase-activating polypeptide (PACAP) promotes neuronal survival and inhibits caspase-3 activity. However, the mechanisms leading to the opposite regulation of caspase-3 by C2-ceramide and PACAP are currently unknown. Here, we show that PACAP prevent...

The currently available data on the distribution of C2 fracture subtypes is sparse. This study was designed to identify the proportions of the second cervical vertebra (C2) fracture subtypes and to present age and gender specific incidences of subgroups. A dataset of all patients treated between 2002 and 2014 for C2 fractures was extracted from the regional hospital information system. C2 fract...

Published data on any association between the CYP2E1 RsaI/PstI (c1/c2) polymorphism and liver cancer risk among east Asians are inconclusive. The aim of this Human Genome Epidemiology (HuGE) review and meta- analysis was to derive a more precise estimation of the relationship. A literature search of Pubmed, Embase, Web of science and CBM databases from inception through July 2012 was conducted....

the oxidative coupling of methane (ocm) performance over na-w-mn/sio2 at elevated pressures has been simulated by adaptive neuro fuzzy inference system (anfis) using reaction data gathered in an isothermal fixed bed microreactor. in the designed neuro fuzzy models, three important parameters such as methane to oxygen ratio, gas hourly space velocity (ghsv), and reaction temperature were conside...

background although the immunosuppressant cyclosporine (csa) is widely used after kidney transplantation over the long term, there is still no firm consensus on the best way to monitor of csa blood levels. objectives cyclosporine (csa) assay is critical for the management of renal transplant recipients due to inter– and intra–patient variation in csa absorption and metabolism. patients and meth...

Two variants of a genetic deficiency of complement protein C2 (C2D) have been previously identified. No C2 protein translation is detected in type I deficiency, while type II deficiency is characterized by a selective block in C2 secretion. Type I C2 deficiency was described in a family in which the C2 null allele (C2Q0) is associated with the major histocompatibility haplotype/complotype HLA-A...

STUDY DESIGN Anatomical study. PURPOSE To evaluate the anatomy of the C2 lamina for translaminar screw placement based on computerized tomographic measurements. OVERVIEW OF LITERATURE C2 translaminar screw insertion is a novel technique for atlanto-axial fixation. The risk of vertebral artery injury can be decreased by this technique. However, a large series of anatomical studies on C2 anat...

NK cells are regulated by inhibiting and activating cell surface receptors. Most inhibitory receptors recognize MHC class I Ags and protect healthy cells from NK cell-mediated autoaggression. However, certain activating receptors, including the human activating killer cell Ig-like receptor (KIR) 2DS1, also recognize MHC class I. This fact raises the question of how NK cells expressing such acti...

The C2 domain is a membrane-targeting domain found in many cellular proteins involved in signal transduction or membrane trafficking. The majority of C2 domains co-ordinate multiple Ca(2+) ions and bind the membrane in a Ca(2+)-dependent manner. To understand the mechanisms by which Ca(2+) mediates the membrane binding of C2 domains, we measured the membrane binding of the C2 domains of group I...
