During scanning, they viewed blocks of photographic smoking and control cues.
Following abstinence, greater activation was found in response to smoking cues compared to control cues in parietal (BA 7/31), frontal (BA 8/9), occipital (BA 19), and central (BA 4) cortical regions and in dorsal JNJ-64619178 chemical structure striatum (putamen) and thalamus. In contrast, no smoking cue greater than control cue activations were observed following smoking as usual. Direct comparisons between conditions (satiated vs. abstinent) showed greater brain reactivity in response to smoking cues following abstinence. In addition, positive correlations between pre-scan craving in the abstinent condition and smoking
cue activation were observed in right dorsomedial prefrontal cortex (dmPFC) buy EPZ015938 including superior frontal gyrus (BA 6/10), anterior cingulate gyrus (BA 32), and supplementary motor area (BA 6).
The present findings indicate that smoking abstinence
significantly potentiates neural responses to smoking-related cues in brain regions subserving visual sensory processing, attention, and action planning. Moreover, greater abstinence-induced craving was significantly correlated with increased smoking cue activation in dmPFC areas involved in action planning and decision making. These findings suggest that drug abstinence can increase the salience of conditioned cues, which is consistent with incentive-motivation models of addiction.”
“Backgrounds: IgA nephropathy (IgAN) is the most common primary glomerulonephritis causing end stage renal Vitamin B12 disease (ESRD), and vasculopathy is known to involve disease progression. Klotho, a gene related to aging, has been reported to play a role in atherosclerosis and endothelial dysfunction.
We investigated whether klotho gene polymorphism affect clinical course of IgAN. Methods: The data registered for PREMIER study which enrolled the patients with biopsy proven IgAN were analyzed. Two single nucleotide polymorphisms for klotho gene, G395A of promoter region and C1818T of exon 4, were examined, and investigated the association klotho genotypes with the progression of IgAN and patient survival. Results: Clinical data from 973 patients confirmed about survival were analyzed. The allele frequency was 0.830 and 0.170 for allele G and A, and 0.816 and 0.184 for allele C and T, which were complied with Hardy-Weinberg equilibrium (p = 0.996 and 0.531 respectively). Death was observed more frequently in A-allele carriers of G395A polymorphism (0.7 vs 2.6 %, GG vs GA+AA, p = 0.022). Renal survival in Kaplan-Meier survival curve was also worse in same group (p = 0.04). Conclusion: Klotho gene polymorphism was associated with patient survival and disease progression of IgAN.
