Myocardial relaxation is an important energy-dependent process. Hypoxia, unlike ischemia, has not been shown to impair myocardial relaxation. This difference may be because (a) the traditional index to assess isometric muscle relaxation (half time to relaxation or RT((1/2))) reflects both changes in developed tension as well as relaxation and (b) the relaxation process is highly sensitive to te...

background: adolescent pregnancy and childbirth are associated with increased risk and challenges for both mothers and birth outcomes. objective: to investigate the associations of growth change over time with parenting factors and to compare the differences between children born to adolescent and adult mothers in taiwan. materials and methods: the dataset retrieved from taiwan birth cohort stu...

Desmoid tumors (DTs) are a group of rare and benign soft tissue tumors that result from monoclonal proliferation of well-differentiated fibroblasts. Since DTs tend to infiltrate and compress adjacent structures, the location of DTs is one of the most crucial factors for determining the severity of the disease. Furthermore, DTs can further complicate the clinical course of patients when the grow...

The impact of an insect-free artificial diet provided at nymphal and/or adult stage upon the developmental rate, life table parameters, and fertility table parameters was examined for Podisus maculiventris (Say). This study showed that when fed an insect-free artificial diet during both the nymphal and adult stage, developmental time was prolonged, preoviposition period was extended, and reprod...

where Z t is the proportion of the population infected with disease against the total population; p ∈ 0, 1 is the vertical distribution probability; B is the birth rate independent on the total population; β is the constant transmission rate; C is the contact rate between individuals; α is the increase of the death rate suffering from infectious disease. It turns out that this model can be used...

earthquakes are a particular concern because of the serious hazard they present. the existence of seismicity patterns such as the foreshock and aftershock clusters, doughnut pattern, seismic quiescence etc show that the earthquake occurrence in the active tectonic regions is not random and clustering phenomena are obvious characteristics of these events in space and time. fractal analysis, as a...
