Porcine circovirus 2 (PCV2) has been prevalent in swine herds in China since 2002, causing severe economic loss to the pig industry. The number of live pigs in southeast China is > 20 million. Since information on the genetic variation of PCV2 in the Fujian province is limited, the objective of the present work was to investigate the epidemiological and evolutionary characteristics of PCV2 in southeast China from 2013 to 2017. Of the 685 samples collected from 90 different swine herds from 2013 to 2017, 356 samples from 84 different swine herds were positive for PCV2. PCV2a, PCV2b, PCV2d, and PCV2e co-existed in the Fujian province, with PCV2d-2 being the predominant circulating strain in swineherds and PCV2e being reported for the first time in China. Strikingly, PCV2-FJ-water DNA comes from contaminated river water and not infected animals. Sequence comparison among all isolates indicated that 92 isolates shared approximately 78.7–100% nucleotide identity and 74.5–100% amino acid identity for open reading frame (ORF). Amino acid alignment showed that the Cap protein of PCV2e and two strains (CN-FJ-CTS04 and FJ-6S-2017) differed markedly from those of PCV2a, PCV2b, PCV2c, and PCV2d. These results indicated that various PCV2 genotypes exist in China, and that PCV2 is continuously evolving, leading to rapid emergence of new variant stains.
Background. Different anticancer drugs are used in combination or alone to treat breast cancer depending upon the status of the patient. Oncologists need to know a drug’s efficacy; therefore, they compare different chemotherapies by considering side effects and overall survival so that suitable drugs can be prescribed. We present a comparison of adjuvant chemotherapies treating breast cancer with docetaxel plus cyclophosphamide (TC) and doxorubicin plus cyclophosphamide (AC) showing pathological markers and overall survival.
Method. For 4 to 8 cycles, (after every 21 days) out of 358 patients, 189 received TC (140 ml/m2 of docetaxel (IV) plus 1000 mg/m2 of cyclophosphamide) and 169 women were treated with AC (50/100 ml/m2 of doxorubicin (IV) plus 1000 mg/m2 of cyclophosphamide. On the basis of patients’ assessment by pathological markers, side effects of docetaxel, doxorubicin and cyclophosphamide are listed in our database using R programming language. The common factors and side effects given in MedlinePlus, NIH US database and from our database are separated to be included in comparison for this study. Statistically, we used Chi-Square Test for Homogeneity of Proportions at α = 0.05.
Results. There was no significant difference between proportions of patients with vomiting, extreme tiredness, diarrhoea, mild anaemia, stability and overall survival because p value > 0.05. However, p value < 0.05 for AC remains less toxic by 22.6%, 25.7% and 25.3% than TC in changes in taste, muscle pain and hands burning respectively, whereas TC remains less toxic by 52.9%, 26.3%, 11.3%, 32.5%, 15.5% and 1.75% in dizziness, sore throat, moderate anaemia, weight loss, blood transfusion and haemoglobin level respectively.
Discussion. TC is less toxic than AC in more aspects, whereas both combinations have same overall survival rate.
Background. Participation rate is one of the main challenges medical researchers face. We examined how demographic background and trust in medical research affect the willingness of people to participate in medical research in Taiwan.
Methods. Data from the 2011 Taiwan Genomic Survey were used. A total of 3,159 people aged 18 to 70 years were sampled, and 1,538 of them completed the survey. Missing data were excluded. A total of 1,389 respondents were included in the final analysis.
Results. About 12 percent of the respondents answered that they would be willing to participate in medical research. Respondents who had a college degree or above and were married orlived with a significant other were less likely to participate in medical research. By contrast, respondents who were men and who or their close family members had a biomedicine-related degree were more likely to participate in medical research. After adjustment for demographic factors, respondents who expressed trust in doctors who conduct medical research, agreed that doctors would never ask them to join a medical research study that might harm them, thought that participating in a medical research study is safe, and agreed that medical researchers have no selfish reasons for doing research were more likely to participate in medical research.
Discussion. Some of our findings, such as the effect of education level and marital status on participation in medical research, are different from the findings of most previous studies conducted in other countries. This study is useful for the development of strategies for improving participant recruitment.
Is this open peer review?
No, peer review is still single-blind and all recommendations are private between the authors and Academic Editor. However, any reviewer has the option to sign their report, and once accepted for publication then that review can be shown publicly - again this is optional.
Will I be guaranteed to review if I volunteer?
No. Volunteering is not a guarantee that you will be asked to review. This is for many reasons. For one, reviewers must have relevant qualifications for any manuscript and void of any conflicts of interest. Additionally, it could be that enough reviewers have accepted an invitation to review already, in which case we would not invite any more.
Why aren't there more manuscripts available?
Manuscripts are shown when authors have opted-in for obtaining reviewers through the reviewer-match service. Additionally, there may already be enough reviewers found through other means, for example, invitations sent by the Academic Editor in charge.
What are the editorial criteria?
Please visit the editorial criteria page for initial guidance. You will also be given additional information if invited to review.
