The character of cytokine response in AIDS patients may be directly related to the stimulus employed in test systems. There is no evidence for Th1/Th2 dysregulation. Cytokine elevations in AIDS patients generally are reflective of chronic infection (the virus). Lymphocytes from AIDS patients do not respond as well to stimulation as do those from normal healthy volunteers. The stimulated lymphocyte response in AIDS patients suggests there is underlying low-grade host versus virus reaction in these patients (exaggerated responses of IL-3, IL-4, IL-8, TGF-B).
Genetics and gene therapy in cardiovascular diseases / Strategies to improve the treatment of hypertensionCRISPR/dCas9-VPR system resulted in an increase of the ratio between cardiac and skeletal muscle isoforms of Trdn (Figure 1b). Down-regulation of Trdn-AS expression using gapmeRs had no effect on the cardiac/skeletal muscle ratio. Figure 1 Conclusion: We identified a lncRNA named TRDN-AS which regulates the balance between cardiac and skeletal muscle isoforms of TRDN at the epigenetic level. Since TRDN is associated with heart failure, these results suggest a role for TRDN-AS in the development of heart failure.

HL-1 cardiomyocytes were cotransfected with SP-dCas9-VPR and gRNA_Cloning Vector with specific guide RNA (sgRNA) or without (Control) target sequence. Cells were harvested after 48h. 5 independent experiments were performed. Background/Introduction: Currently, the American and European guidelines recommend combining two out of the following three classes of drug, ACE inhibitors/angiotensin-receptor blocker (A), calcium antagonist (C) and thiazide diuretics (D), for initial combination treatment in high risk hypertension patients. However, the real-world evidence of head-to-head comparison among the recommended regimens is still limited. Purpose: We aim to compare the therapeutic effectiveness of combination regimens between patients initiating antihypertensive treatment. Methods: From Korea National Health Insurance sample cohort database, we identified eligible patients without previous history of cardiovascular disease who were started on and received prescription of dual anti-hypertensive treatment for more than 180 days between 2003 and 2012. The patients were matched for each comparison set by means of a high-dimensional propensity score matching (HdPS) algorithm to compare the efficacy of A + D vs A + C, A+D vs C+D, and A+C vs C+D combination treatment. Primary end point was major adverse cardiac and cerebrovascular events (MACCE)-a composite of all-cause mortality, myocardial infarction, heart failure and stroke. Cardiovascular (CV) mortality and the individual components of the primary endpoint comprised the secondary end points. Results: Total of 14098 patients were identified to meet eligible criteria with follow-up duration of 5.31±3.12 years. Among them, 4109, 2235 and 1646 patients were allocated to A + D vs A + C, A+D vs C+D, and A+C vs C+D group, respectively. There was no significance difference in the primary endpoint between groups: A+D vs A+C (HR 0.89, 95% CI 0.76-1.04), A+D vs C+D (HR 0.87, 95% CI 0.74-1.03), and A+C vs C+D (HR 0.95, 95% CI 0.79-1.15). All three recommended regimens had similar efficacy in secondary endpoints (all P>0.05). Conclusions: To our knowledge, this is the first real-world comparative effectiveness research comparing the recommended regimens of dual...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
