While our study is limited by size, our results suggest that NOACs may be a non-inferior alternative to traditional anticoagulation and that further study is warranted.
Tamoxifen (Tam) is effective for the treatment and prevention of breast cancer. However, it has toxic drawbacks and has limitedduration utility because, over time, human tumours become refractory to Tam. Recently, a new nontoxic peptide, a-fetoproteinderived peptide (AFPep) has been proposed for the treatment and prevention of breast cancer. The purpose of this paper is to determine whether combining AFPep with Tam would increase efficacy and reduce toxicity in experimental models of breast cancer. Low doses of AFPep and Tam were more effective in combination than either agent alone against breast cancer growth in cell culture, in tumour-xenografted mice, and in carcinogen-exposed rats. a-Fetoprotein-derived peptide interfered with Tam-induced uterine hyperplasia in immature mice, and showed no toxic effects. Unlike Tam, AFPep did not inhibit binding of oestradiol (E 2 ) to oestrogen receptor (ER). Thus, these two agents utilise different mechanisms to interfere with ER functionality, yet work cooperatively to reduce breast cancer growth and alleviate Tam's troubling toxicity of uterine hyperplasia and appear to be a rational combination for the treatment of ER-positive breast cancer.
In the United States, hypertrophic cardiomyopathy and coronary artery anomalies account for the leading two causes of sudden death in athletes. We present a case of a patient with an anomalous origin of the left main from the right coronary sinus with associated gene-confirmed hypertrophic cardiomyopathy. The patient underwent surgical repair with unroofing of the intramural portion of the left main coronary artery with a good result. We also review the reported cases in the medical literature describing this uncommon association between anomalous coronary artery origin and hypertrophic cardiomyopathy.
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.
