Journal ArticleDOI
The Cheetah's Conservation Controversy
TL;DR: The article revives spurious and fallacious arguments that have been made earlier and concludes that " . . . the genetic constitution of the cheetah does not appear to compromise the survival of the species."
Journal ArticleDOI
The superolateral portal for arthroscopy of the shoulder
TL;DR: A new portal for shoulder arthroscopy that is safe to insert is presented, providing a panoramic view of the glenohumeral joint (especially anteriorly), and allowing unobstructed observation of large instruments passed through more traditional anterior portals nearby.
Journal ArticleDOI
Improved single nucleotide polymorphisms detection using conjugated polymer/surfactant system and peptide nucleic acid.
TL;DR: An improved assay for the detection of single nucleotide polymorphisms (SNP) of mutant DNA using a combination of peptide nucleic acid (PNA) probes, a cationic conjugated polymer (CCP) and non-ionic surfactant is reported, showing enhancement in the discrimination between mutant and wild type DNA.
Journal ArticleDOI
Exposure to FIV and FIPV in wild and captive cheetahs
TL;DR: A worldwide survey of serum and plasma from cheetah and other nondomestic felids for antibodies to FIV and FIPV, based on Western blot and immunofluorescence assays concludes that the cat model may also reflect historic infections that have approached an evolutionary balance between the pathogen and immune defenses of their feline host species.
