Cardiac troponins can be useful in monitoring cardiac injury following perinatal distress. We report here an increase of cardiac troponin I (cTnI) to 2.84 microg/l at 3 weeks (age-related median: 0.07 microg/l) followed by normalization in a newborn with an uneventful clinical course after resuscitation at birth. Serial echocardiographs showed ...

AIMS: To evaluate how the frictional coefficient of the porcine temporomandibular joint (TMJ) is affected by an impairment of the synovial lubrication produced by an experimental abrasion of the articular cartilage and the application of hyaluronic acid (HA) with different molecular weights to the abraded cartilage surfaces. METHODS: Erosion of ...

The antennal lobe was examined by Golgi-silver impregnation to differentiate the glomeruli depending on the source and types of inputs. Thirty-five of the 43 'identified' olfactory glomeruli were Golgi-silver impregnated in the present study. Seven glomeruli compared to three, reported previously, were found to be targets of maxillary palp chemosensory ...

Experimental as well as clinical studies have demonstrated that room air is as efficient as pure oxygen for newborn resuscitation. Recent data even indicate that outcome is improved if pure oxygen is avoided. Thus, in a meta-analysis, neonatal mortality was significantly lower in those newly born infants resuscitated with 21% ...

A short cut review was carried out to establish whether the two thumb technique was superior to the two finger technique in delivering effective chest compressions in infants with cardiac arrest. Altogether 175 papers were found using the reported search, of which four presented the best evidence to answer the ...

The study of the origin and early evolution of birds has never produced as much excitement and public attention as in the past decade. Well preserved and abundant new fossils of birds and dinosaurs have provided unprecedented new evidence on the dinosaurian origin of birds, the arboreal origin of avian ...

Kinesins are motor proteins that use the hydrolysis of ATP to do mechanical work. Most of these motors translocate cargo along the surface of the microtubule (MT). However, a subfamily of these motors (Kin-I kinesins) can destabilize MTs directly from their ends. This distinct ability makes their activity crucial during ...
