- Genetic and epigenetic changes in fibrosis-associated hepatocarcinogenesis in mice.
- Chappell G1, Kutanzi K, Uehara T, Tryndyak V, Hong HH, Hoenerhoff M, Beland FA, Rusyn I, Pogribny IP.Author information 1Department of Environmental Sciences and Engineering, University of North Carolina, Chapel Hill, NC.AbstractHepatocellular carcinoma (HCC) is one of the most prevalent cancers and is rising in incidence worldwide. The molecular mechanisms leading to the development of HCC are complex and include both genetic and epigenetic events. To determine the relative contribution of these alterations in liver tumorigenesis, we evaluated epigenetic modifications at both global and gene specific levels, as well as the mutational profile of genes commonly altered in liver tumors. A mouse model of fibrosis-associated liver cancer that was designed to emulate cirrhotic liver, a prevailing disease state observed in most humans with HCC, was used. Tumor and nontumor liver samples from B6C3F1 mice treated with N-nitrosodiethylamine (DEN; a single ip injection of 1 mg/kg at 14 days of age) and carbon tetrachloride (CCl4 ; 0.2 ml/kg, 2 times/week ip starting at 8 weeks of age for 14 weeks), as well as corresponding vehicle control animals, were analyzed for genetic and epigenetic alterations. H-ras, Ctnnb1 and Hnf1α genes were not mutated in tumors in mice treated with DEN+CCl4 . In contrast, the increased tumor incidence in mice treated with DEN+CCl4 was associated with marked epigenetic changes in liver tumors and nontumor liver tissue, including demethylation of genomic DNA and repetitive elements, a decrease in histone 3 lysine 9 trimethylation (H3K9me3) and promoter hypermethylation and functional downregulation of Riz1, a histone lysine methyltransferase tumor suppressor gene. Additionally, the reduction in H3K9me3 was accompanied by increased expression of long interspersed nucleotide elements 1 and short interspersed nucleotide elements B2, which is an indication of genomic instability. In summary, our results suggest that epigenetic events, rather than mutations in known cancer-related genes, play a prominent role in increased incidence of liver tumors in this mouse model of fibrosis-associated liver cancer.

During the last decades repetitive transcranial magnetic stimulation (rTMS), an alternative method using electric stimulation of the brain, has revealed possible alternative to ECT in the treatment of depression. There are some clinical trials comparing their efficacies and safeties but without clear conclusions, mainly due to their small sample sizes. In the present study, a meta-analysis had been carried out to gain statistical power. Outcomes were response, remission, acceptability and cognitive effects in depression. Following a comprehensive literature search that included both English and Chinese language databases, we identified all randomized controlled trials that directly compared rTMS and ECT for major depression. 10 articles (9 trials) with a total of 425 patients were identified. Methodological quality, heterogeneity, sensitivity and publication bias were systematically evaluated. ECT was superior to high frequency rTMS in terms of response (64.4% vs. 48.7%, RR=1.41, p=0.03), remission (52.9% vs. 33.6%, RR=1.38, p=0.006) while discontinuation was not significantly different between the two treatments (8.3% vs. 9.4%, RR=1.11, p=0.80). According to the subgroup analysis, the superiority of ECT was more apparent in those with psychotic depression, while high frequency rTMS was as effective as ECT in those with non-psychotic depression. The same results were obtained in the comparison of ECT with low frequency rTMS. ECT had a non-significant advantage over high frequency rTMS on the overall improvement in HAMD scores (p=0.11). There was insufficient data on medium or long term efficacy. Both rTMS and ECT were well tolerated with only minor side effects reported. Results based on 3 studies suggested that specific cognitive domains such as visual memory and verbal fluency were more impaired in patients receiving ECT. In conclusion, ECT seemed more effective than and at least as acceptable as rTMS in the short term, especially in the presence of psychotic depression. This review identified the lack of good quality trials comparing the long-term outcome and cognitive effects of rTMS and ECT, especially using approaches to optimize stimulus delivery and reduce clinical heterogeneity.

- Transcranial magnetic stimulation (TMS)/repetitive TMS in mild cognitive impairment and Alzheimer's disease.
- Nardone R1, Tezzon F, Höller Y, Golaszewski S, Trinka E, Brigo F.Author information 1Department of Neurology, Christian Doppler Klinik, Paracelsus Medical University, Salzburg, Austria; Department of Neurology, Franz Tappeiner Hospital, Merano, Italy.AbstractSeveral Transcranial Magnetic Stimulation (TMS) techniques can be applied to noninvasively measure cortical excitability and brain plasticity in humans. TMS has been used to assess neuroplastic changes in Alzheimer's disease (AD), corroborating findings that cortical physiology is altered in AD due to the underlying neurodegenerative process. In fact, many TMS studies have provided physiological evidence of abnormalities in cortical excitability, connectivity, and plasticity in patients with AD. Moreover, the combination of TMS with other neurophysiological techniques, such as high-density electroencephalography (EEG), makes it possible to study local and network cortical plasticity directly. Interestingly, several TMS studies revealed abnormalities in patients with early AD and even with mild cognitive impairment (MCI), thus enabling early identification of subjects in whom the cholinergic degeneration has occurred. Furthermore, TMS can influence brain function if delivered repetitively; repetitive TMS (rTMS) is capable of modulating cortical excitability and inducing long-lasting neuroplastic changes. Preliminary findings have suggested that rTMS can enhance performances on several cognitive functions impaired in AD and MCI. However, further well-controlled studies with appropriate methodology in larger patient cohorts are needed to replicate and extend the initial findings. The purpose of this paper was to provide an updated and comprehensive systematic review of the studies that have employed TMS/rTMS in patients with MCI and AD.

- Aspirin Desensitization: Useful Treatment for Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) in Aspirin-Exacerbated Respiratory Disease (AERD)?
- Klimek L1, Dollner R, Pfaar O, Mullol J.Author information 1Center for Rhinology and Allergology, An den Quellen 10, 65183, Wiesbaden, Germany, Ludger.Klimek@Allergiezentrum.org.AbstractAspirin intolerance syndrome is due to disturbances in the arachidonic acid metabolism implicating both the lipoxygenase and cyclooxygenase pathways. This results in imbalances of eicosanoid, leukotriene and prostaglandin synthesis. Thus, preinflammatory cysteinyl leukotrienes increase and antiinflammatory prostaglandins (PG) such as PGE2 decrease. Clinically, intolerance reactions to nonsteroidal antiinflammatory drugs (NSAIDs) can lead to different clinical manifestations; five phenotypes of the aspirin intolerance syndrome are listed in the ENDA classification. Aspirin-exacerbated respiratory disease (AERD) is the most common phenotype characterized by an eosinophil-dominated inflammatory disease of the airways that presents clinically with nasal polyps, chronic sinusitis and bronchial asthma. About 34 % of patients with aspirin-induced asthma and rhinosinusitis are thought to have AERD. Important biochemical findings in many AERD patients are increased basal leukotriene levels (at least in cell cultures) that excessively increase after intake of COX-1 inhibitors. Aspirin desensitization uses the repetitive application of aspirin to induce a tolerance to NSAIDs, especially COX-1 inhibitors. After a dose-increase phase reaching a threshold dose, a dose-continuation phase is performed. For application, the nasal, bronchial, oral and intravenous routes have been described. Aspirin desensitization has been proven to be efficacious and safe and was able to reduce the need for other medications in AERD patients.
