The International Mouse Knockout Consortium aims to generate a knockout mouse for every single gene on a C57BL/6 background. Our ability to generate such mice is hampered by the poor economics of producing blastocysts to achieve germline transmission of C57BL/6 embryonic stem (ES) cells. We demonstrate superior utility of (C3H x BALB/c)F1 blastocysts compared with BALB/c blastocysts, with blastocyst numbers and germline transmission from subsequent chimeras at a rate 2- to 3-fold higher than that produced with BALB/c blastocysts.
False information by vaccination movements as a challenge for public healthThe analysis of the characteristics of refusals to carry out preventive vaccinations, both in historical and contemporary perspective, showed that the dissemination of false information by vaccination movements, had and has a significant impact on the level of vaccination in the scope of individual preventive vaccinations, e.g. against polio, tetanus and diphtheria and it is real public health challenge. It is necessary to analyze the nature of the message in terms of the sender's intentions, i.e. to distinguish between misinformation and disinformation. Preparation of an appropriate communication strategy in public health in this regard, seems necessary and crucial in terms of maintaining a high level of confidence in preventive vaccinations, and thus population resistance in the case of infectious diseases. Type of research methodology/research approach used: literature analysis.
Children who underwent surgery for complex congenital heart defects present worse exercise capacity than their healthy peers. In adults and adolescents, heart failure is assessed on the basis of clinical symptoms using the New York Heart Association (NYHA) score, while in an infant Ross scale; heart failure can also be evaluated by other parameters. The purpose of this study was to compare the degree of exercise tolerance in children after surgery for complex heart defects, assessed by the ratio of maximum oxygen uptake (VO2max) and the brain natriuretic peptide (N-terminal fragment of the prohormone brain-type natriuretic peptide [NT-proBNP]) concentration.The study group consisted of 42 children, ages 9 to 17 years (mean 14.00 ± 2.72). Among them there were 22 children with tetralogy of Fallot (ToF) after total correction, 18 children with transposition of the great arteries (d-TGA) after the arterial switch operation, and 2 children with single ventricle (SV) after the Fontan operation. All but 1 child were in NYHA class I. The control group consisted of 20 healthy children. Outcomes of interest were the ratio of VO2max, determined during ergospirometry, and the level of NT-proBNP. The statistical analysis was performed and the groups were considered significantly different for P < 0.05.There was no statistically significant correlation between NT-proBNP and maximum oxygen uptake (VO2) kg−1 min−1 in the study group compared with the control group.The VO2max in the test group had a mean value less (34.6 ± 8.0) than controls (38.4 ± 7.7), and the differences were statistically significant (P = 0.041). In contrast, the average concentration of NT-proBNP in the study group was higher than controls (117.9 ± 74.3 vs 18.0 ± 24.5), and these differences were statistically significant (P < 0.001).After operations for complex heart defects (ToF, TGA, and SV), children have worse heart function parameters and exercise capacity than the healthy population. To control this, we recommend postoperative ergospirometry and determination of NT-proBNP concentrations.
Urgent solutions range from re-engineering of the macroeconomic basis of cancer costs (e.g. value-based approaches to bend the cost curve and allow cost-saving technologies), greater education of policy makers, and an informed and transparent regulatory system. We have analyzed a total of 856 cancer patients were registered in the onco-AIFA for various drugs. The results have shown that 38.1% of patients have received only few drug administrations and their treatment was stopped within 4 or 12 weeks (depending on the type of the drug schedule). We have examined the reasons, why their treatment was immediately suspended.
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.
