Complete Columbian mammoth mitogenome suggests interbreeding with woolly mammoths [PDF]
Genome Biology, 2011 Abstract Background Late Pleistocene North America hosted at least two divergent and ecologically distinct species of mammoth: the periglacial woolly mammoth (Mammuthus primigenius) and the subglacial Columbian mammoth (Mammuthus columbi).

Biophysical approaches for studying viral entry
FEBS Letters, EarlyView.Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Distal Femoral Derotational Osteotomy for Excessive Femoral Anteversion
Arthroscopy TechniquesExcessive femoral anteversion (FA) is an underappreciated contributor to patellar maltracking and instability. Positive screening for anteversion with a hip examination should be followed by computed tomography scan to confirm and quantify the degree of ...
