Attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy has been used to investigate the effects of three fatty acid esters on skin permeation. Propylene glycol diperlargonate (DPPG), isopropyl myristate (IPM) and isostearyl isostearate (ISIS) were selected as pharmaceutically relevant solvents with a range of lipophilicities and cyanophenol (CNP) was used as a model dru...
Chemotherapy-induced neuropathic pain (CNP) is the major dose-limiting factor in cancer chemotherapy. However, the neural mechanisms underlying CNP remain enigmatic. Accumulating evidence implicates the involvement of spinal glia in some neuropathic pain models. In this study, using a vincristine-evoked CNP rat model with obvious mechanical allodynia, we found that spinal astrocyte rather than ...
The effects of activators and inhibitors of protein kinase C (PKC) on the production of C-type natriuretic peptide (CNP) by cultured human aortic endothelial cells were examined. The PKC activators phorbol 12-myristate 13-acetate (PMA) and 1-oleoyl 2-acetyl glycerol (OAG) stimulated CNP release; the maximal effects were apparent at 4 h, at which time release was 934 and 205% of the control valu...
Atrial natriuretic peptide (ANP) and C-type natriuretic peptide (CNP) are important dilators of the pulmonary circulation during the perinatal period. We compared the responses of pulmonary arteries (PA) and veins (PV) of newborn lambs to these peptides. ANP caused a greater relaxation of PA than of PV, and CNP caused a greater relaxation of PV than of PA. RIA showed that ANP induced a greater ...
Contraction of intestinal myofibroblasts (IMF) contributes to the development of strictures and fistulas seen in inflammatory bowel disease, but the mechanisms that regulate tension within these cells are poorly understood. In this study we investigated the role of nitric oxide (NO) signaling in C-type natriuretic peptide (CNP)-induced relaxation of IMF. We found that treatment with ODQ, a solu...
Aiming at combining the good characteristics of a differential scale in representing human cognition and the favorable properties of interval judgments in expressing decision-makers’ uncertainty, this paper proposes the interval cognitive network process (I-CNP) to extend the primitive cognition network process (P-CNP) to handle interval judgments. The key points of I-CNP include a consistency ...
Chitosan nanoparticles (CNP), a kind of widely used drug carrier, have shown potent cytotoxic effects on various tumour cell lines in vitro and in vivo. This study sought to evaluate the antitumour effect of CNP on growth of human hepatocellular carcinoma (BEL7402) and the possible mechanisms involved. Cells were grown in the absence and presence of various concentrations of CNP with mean parti...
Intense research is conducted to identify new molecular mechanisms of angiogenesis. Previous studies have shown that the angiogenic effects of hydrogen sulfide (H2S) depend on the activation of ATP-sensitive potassium channels (KATP) and that C-type natriuretic peptide (CNP), which can act through KATP, promotes endothelial cell growth. We therefore investigated whether direct KATP activation i...
Azarashvili T, Krestinina O, Galvita A, Grachev D, Baburina Y, Stricker R, Evtodienko Y, Reiser G. Ca -dependent permeability transition regulation in rat brain mitochondria by 2 ,3 -cyclic nucleotides and 2 ,3 -cyclic nucleotide 3 -phosphodiesterase. Am J Physiol Cell Physiol 296: C1428–C1439, 2009. First published April 8, 2009; doi:10.1152/ajpcell.00006.2009.—Recent evidence indicates that 2...
We previously reported the secretion of C-type natriuretic peptide (CNP) from vascular endothelial cells and proposed the existence of a vascular natriuretic peptide system composed of endothelial CNP and smooth muscle guanylyl cyclase-B (GC-B), the CNP receptor, and involved in the regulation of vascular tone, remodeling, and regeneration. In this study, we assessed the functional significance...
