Journal ArticleDOI
Applying molecular genetic tools to tiger conservation.
TL;DR: The genetic status of tiger subspecies and populations and implications for developing strategies for the survival of this charismatic species both in situ and ex situ are discussed.
Journal ArticleDOI
Chromosome painting shows that skunks (Mephitidae, Carnivora) have highly rearranged karyotypes.

TL;DR: Mephitidae joins Canidae and Ursidae as the third family of carnivores that are characterized by a high rate of karyotype evolution, suggesting that procyonids have a particular importance for establishing the karyological evolution within the caniforms.
Journal ArticleDOI
Activity levels and polyethylene wear of patients 10 years post hip replacement.
TL;DR: Progressive reduction in activity levels with more elderly hip replacement patients may inform long term planning of hip arthroplasty and implant choice.
Journal ArticleDOI
De novo sequencing, assembly and analysis of eight different transcriptomes from the Malayan pangolin.

TL;DR: The first large-scale sequencing of the critically endangered Manis javanica transcriptomes from eight different organs using Illumina HiSeq technology is provided, yielding ~75 Giga bases and 89,754 unigenes that may be insightful to understand the lipid metabolism system in pangolins.
Journal ArticleDOI

Aleksey Komissarov,Svetlana Galkina,Elena I. Koshel,Maria Kulak,Aleksander G. Dyomin,Stephen J. O'Brien,Stephen J. O'Brien,Elena Gaginskaya,Alsu F. Saifitdinova +8 more
TL;DR: Tandem repeat (GGAAA)n has been identified and found to be the second after telomeric repeat (TTAGGG)n most abundant in the chicken genome, which highlights the complexity of repetitive sequences and update data about organization of sex W chromosome in chicken.
