Journal ArticleDOI
Isolated Closure of Rotator Interval Defects for Shoulder Instability
TL;DR: Fifteen patients noted at surgery to have an isolated defect in the rotator interval and no other pathologic abnormality underwent closure of the defect as an iso lated procedure for recurrent instability symptoms, and in traoperative assessment of each of these shoulders after the closure demonstrated adequate stability, andno other stabilization procedures were performed.
Journal ArticleDOI
Functions, structure, and read-through alternative splicing of feline APOBEC3 genes

TL;DR: The data support a complex evolutionary history of expansion, divergence, selection and individual extinction of antiviral A3 genes that parallels the early evolution of Placentalia, becoming more intricate in taxa in which the arms race between host and retroviruses is harsher.
Journal ArticleDOI
Prevalence of antibodies to feline parvovirus, calicivirus, herpesvirus, coronavirus, and immunodeficiency virus and of feline leukemia virus antigen and the interrelationship of these viral infections in free-ranging lions in east Africa
Regina Hofmann-Lehmann,Fehr D,Markus Grob,Muhamed Elgizoli,Craig Packer,Janice S. Martenson,Stephen J. O'Brien,Hans Lutz +7 more
TL;DR: Observations indicate that, although the pathological potential of these viral infections seemed not to be very high in free-ranging lions, relocation of seropositive animals by humans to seronegative lion populations must be considered very carefully.
BookDOI
Atlas of Mammalian Chromosomes
TL;DR: This book is intended to serve as a “roadmap” for future generations of scientists and philosophers to consider the role of language in the exploration of human evolution.
Journal ArticleDOI
Rapid evolution of a heteroplasmic repetitive sequence in the mitochondrial DNA control region of carnivores.
TL;DR: The pattern of change seen within and between species suggests that a dominant mechanism involved in the evolution of these arrays is DNA slippage and the evolutionary implications of the observed patterns of variation and extreme levels of heteroplasmy are discussed.
