background: historically open surgical drainage has been the treatment of choice for pyogenic liver abscess. the records of 54 patients with pyogenic liver abscess were reviewed to determine whether earlier diagnosis with current imaging tests and definitive treatment with antibiotics and aspiration drainage was an effective alternative to surgery. methods: the clinical features, laboratory tes...
The year 2014 saw more than a thousand new mitochondrial genome sequences deposited in GenBank—an almost 15% increase from the previous year. Hundreds of peer-reviewed articles accompanied these genomes, making mitochondrial DNAs (mtDNAs) the most sequenced and reported type of eukaryotic chromosome. These mtDNA data have advanced a wide range of scientific fields, from forensics to anthropolog...
As a growth regulator, PDGF-BB plays a crucial role in regulating neuronal survival and cell differentiation during embryonic development and in the adulthood. The multiple roles and mechanisms of PDGF-BB are still not known, especially involved in plasticity after spinal cord injury. However, before we can carry out further investigations a transgenic animal model with PDGF-BB down-regulation ...
Plesiosaurs may be divided into two general morphotypes, based on body shape. ‘Pliosauromorphs’ have a large head and a short neck—traditionally thought to be pliosaurs, while ‘plesiosauromorphs’ have a small head and long neck, and have been seen as plesiosauroids. This is in fact an oversimplification, and today, detailed analysis and investigations of plesiosaur anatomy suggest that these mo...
Aberrant wound-healing responses to injury have been implicated in the development of pulmonary fibrosis, but the mediators directing these pathologic responses have yet to be fully identified. We show that lysophosphatidic acid levels increase in bronchoalveolar lavage fluid following lung injury in the bleomycin model of pulmonary fibrosis, and that mice lacking one of its receptors, LPA1, ar...
English teachers are frequently asked to help colleagues prepare presentations for internationalconferences. Sometimes this assistance takes the form of a language course or tutorials focusingon the spoken language. Contact time is short but the participants are highly motivated. Whattype of pronunciation work will provide the greatest payoff in terms of successfully beingunders...
