Tumorigenicity in vivo and induction of mutagenesis and DNA repair in vitro by aclacinomycin A and marcellomycin: structure-activity relationship and predictive value of short-term tests.
The genotoxicity of two new anthracycline antitumor antibiotics, aclacinomycin A and marcellomycin, which are potent cytostatic agents similar to Adriamycin and daunomycin, was investigated in various assays. In contrast to Adriamycin and daunomycin, both agents were devoid of mutagenic activity in the Salmonella-microsome assay as well as in a mammalian cell assay using V79 Chinese hamster cel...
متن کاملEvaluation of the Predictive Value of Umbilical Cord Serum Bilirubin Level for the Development of Subsequent Hyperbilirubinemia in Term and Late-Preterm Neonates
Background: Considering the increasing rates of early hospital discharge and kernicterus in healthy full term newborns, timely identification of neonates at risk of severe hyperbilirubinemia is of great significance. The aim of this study was to investigate the predictive value of umbilical cord serum (UCS) bilirubin level for subsequent hyperbilirubinemia. Moreover, we compared the predictive ...
متن کاملA gene expression biomarker provides early prediction and mechanistic assessment of hepatic tumor induction by nongenotoxic chemicals.
There are currently no accurate and well-validated short-term tests to identify nongenotoxic hepatic tumorigens, thus necessitating an expensive 2-year rodent bioassay before a risk assessment can begin. Using hepatic gene expression data from rats treated for 5 days with one of 100 structurally and mechanistically diverse nongenotoxic hepatocarcinogens and nonhepatocarcinogens, a novel multige...
متن کاملFirst Trimester Potential Biochemical Predictive Tests for Gestational Diabetes Mellitus: A Systematic Review
Objective: Gestational diabetes mellitus (GDM) is the most common metabolic complication during pregnancy. So, a large number of studies have evaluated the usefulness of different screening tests. The aim of this study was focused on the potential of only first-trimester screening used in the prediction of GDM. Materials and Methods: In this systematic review, we searched PubMed, EMBASE, and S...
متن کاملLetter to Editor: Positive predictive value of diabetes mellitus risk assessment
Diabetes mellitus (DM) is an important public health challenge [1 ].Different studies predicted that the frequency of diabetic patients will be increased to 642 million throughout the world by 2040 [2]. A notable percentage of diabetic patients are not aware of their disease (approximately 30% in Iran) [3]. Lag in the diagnosis of DM raises the expense of controlling disease and makes the progn...
