What makes something alive or dead? Something is alive if it exhibits all of the characteristics of living things. If it doesn't exhibit every characteristic, then it is not living. Something is dead once it stops exhibiting all of the characteristics of life.Five...
Although a highly visible component of the West Indian herpetofauna, few data address the biology of Curly-Tailed Lizards (Leiocephalus). We examined sexual dimorphism in size and head shape and reproductive life-history characteristics for five species of Leiocephalus from the Dominican Republic. Man...

Previous studies have shown that within one or two years after the initial infection, the persistence of high-risk HPV infection is highly predictive of the lifetime risk of pre-invasive and invasive cervical tumors. HPV genotype seems to be the most important factor of persistence, among which...

We discuss the clinical characteristics and prognostic significance of adult individuals with PTPN11 mutations who have developed acute myeloid leukemia (AML) (none acute promyelocytic leukemia). Next generation sequencing and Sanger sequencing were used to detect 51 gene mutations, and multiplex-PCR was...
Herbs might be the most appropriate plant life form for laboratory-based experiments. The life forms of Polygalaceae include trees, shrubs and herbs, while Quillajaceae and Surianaceae are found only as trees (Stevens 2001). Thus, Polygalaceae species may be the most appropriate non-leg...
Mesenchymal stem/stromal cells (MSCs) derived from placental tissue show great therapeutic potential and have been used in medical treatment, but the similarity and differences between the MSCs derived from various parts of the placenta remain unclear. I
Such use of radium-223 could avoid the drawbacks of sequential use of novel hormone agents, which may have limited and short-lived benefit [24,25,26,27,28,29,30], while acknowledging physicians’ and patients’ preferences to delay chemotherapy to avoid toxicities that affect quality of life ...
