BACKGROUND & AIMS: Non-alcoholic fatty liver disease (NAFLD) is a common and strong risk factor for cardiovascular disease and hepatocellular carcinoma. The rapid acceleration of the increase in NAFLD prevalence has exceeded the trends observed for obesity, and has been driven by multiple factors. The aim of this study was to investigate the correlation between the serum levels of folic acid, the endogenous source of methyl groups for DNA methylation, and NAFLD in Chinese adults. METHODS: The correlations between the serum folic acid levels and NAFLD were investigated in two independent cohorts of 70 subjects who underwent a liver biopsy and 130 subjects with varying liver fat contents, as measured using proton magnetic resonance spectroscopy ((1)H-MRS)...

Two oxidovanadium(IV) complexes carrying Schiff base ligands obtained from the condensation of 4,5-dichlorobenzene-1,2-diamine and salicylaldehyde derivatives were synthesised and characterised, including their X-ray crystallographic structures. They were evaluated as dipeptidyl peptidase IV (DPP-IV) inhibitors for the treatment of type 2 diabetes. These compounds were moderate inhibitors of DPP-IV, with IC50 values of ca. 40μM. In vivo tests showed that complexes 1 and 2 could lower significantly the level of glucose in the blood of alloxan-diabetic mice at doses of 22...

OBJECTIVE: To test the hypothesis that cardiac-directed expression of the cytoplasmic domains of adenylyl cyclase-6 (AC6) would have beneficial effects on the heart. BACKGROUND: Eliminating the two transmembrane domains of AC6 yields a protein with an intact catalytic domain that is disengaged from membrane-associated β-adrenergic receptor stimulation, but with enhanced propensity for intracellular interactions. METHODS: We constructed a peptide of the C1 and C2 segments of AC6 (C1C2), expressed C1C2 in an adenovirus vector and generated transgenic lines with cardiac-directed C1C2 expression, which underwent sustained isoproterenol (Iso) infusion...

Transient receptor potential melastatin 2 (TRPM2), a calcium-permeable non-selective cation channel, is reported to mediate brain damage following ischemic insults in adult mice. However, the role of TRPM2 channels in neonatal hypoxic-ischemic brain injury remains unknown. We hypothesize that TRPM2(+/-) and TRPM2(-/-) neonatal mice have reduced hypoxic-ischemic brain injury. To study the effect of TRPM2 on neonatal brain damage, we used 2,3,5-triphenyltetrazolium chloride (TTC) staining to assess the infarct volume and whole brain imaging to assess morphological changes in the brain...

Cell-penetrating peptides (CPPs) are increasingly important in transporting macromolecules across cell membranes, but their use remains confined to narrow clinical applications due to the systemic toxicity induced by their positive charges. Several newly discovered electronic neutral penetrating peptides are not attracting much attention because their penetrating capacity is normally far less powerful than cationic or amphiphilic CPPs. In this study, we found the electronic neutral cyclic peptide cyclosporin A (CsA) exhibited 5...

Podocyte injury and depletion are essential events involved in the pathogenesis of diabetic nephropathy (DN). As a terminally differentiated cell, podocyte is restricted in 'post-mitosis' state and unable to regenerate. Re-entering mitotic phase will cause podocyte disastrous death which is defined as mitotic catastrophe (MC). Murine double minute 2 (MDM2), a cell cycle regulator, is widely expressed in renal resident cells including podocytes. Here, we explore whether MDM2 is involved in podocyte MC during hyperglycaemia...

Neuropathological injury in the mammalian adult central nervous system (CNS) may cause axon disruption, neuronal death and lasting neurological deficits. Failure of axon regeneration is one of the major challenges for CNS functional recovery. Recently, the cAMP/PKA signaling pathway has been proven to be a critical regulator for neuronal regeneration, neuroplasticity, learning and memory. Also, previous studies have shown the effects of Chinese medicines on the prevention and treatment of CNS dysfunction mediated in part by cAMP/PKA signaling...

Ai-Hua Gao, Mei-Shan Wang
The photoisomerization mechanisms of N-salicilydenemethylfurylamine upon excitation to the first singlet state are investigated by means of surface-hopping dynamics simulations based on the Zhu-Nakamura theory. Due to different orientations of the methyl-furyl part with respect to the salicylaldimine part and different orientations of hydroxy group with respect to the benzene ring, various stable structures are obtained in the optimization. The enol isomer, S0-ENOL-5a, is the most stable conformer. An ultrafast excited-state intramolecular proton transfer is observed after photoexcitation of the most stable enol conformer and then the molecule reaches the excited-state minimum...
