We revealed up-regulation of miR-19b in response to 5-FU and potential targets of miR-19b mediating the cell cycle under treatment with 5-FU. Our study provides an important insight into the mechanism of 5-FU resistance in colorectal cancers.
Double-chambered left ventricle (DCLV) is a particularly rare congenital entity characterized by the presence of two ventricular cavities separated by an abnormal muscle band. An asymptomatic 15-year-old boy was referred to our hospital because of electrocardiographic (ECG) abnormalities. His initial transthoracic echocardiography (TTE) demonstrated a DCLV with mild left ventricular systolic dysfunction. During a 5-year follow-up period, he remained symptom free with no changes in ECG and conventional TTE findings. However, two-dimensional speckle tracking echocardiography revealed a subtle progressive deterioration of left ventricular systolic function during the 5-year follow-up.
Addition of intravenous nicorandil to standard therapy for urgent phase AHFS improved dyspnea and left ventricular diastolic function but not 60-day outcome.
Systemic osteosclerosis is a rare complication of hematological malignancies. Primary myelofibrosis and acute megakaryocytic leukemia are known as underlying diseases; however, lymphoid tumors have rarely been reported. Here we describe a case of a 50‐year‐old man with severe systemic osteosclerosis associated with primary bone marrow B‐cell lymphoma. Analysis of bone metabolic markers revealed a high turnover of bone metabolism and an increase in serum osteoprotegerin levels. These results suggest the involvement of osteoprotegerin in the pathogenesis of osteosclerosis associated with hematological malignancies.
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.
