BACKGROUND Administration of fluid to improve cardiac output is the mainstay of hemodynamic resuscitation. Not all patients respond to fluid therapy, and excessive fluid administration is harmful. Predicting fluid responsiveness can be challenging, particularly in children. Numerous hemodynamic variables have been proposed as predictors of fluid responsiveness. Dynamic variables based on the he...

We constructed a physical map of O. sativa ssp. japonica cv. ZH11 and compared it and its random sample sequences with the Nipponbare RefSeq derived from the same subspecies. This comparison showed that the two japonica genomes were highly syntenic but revealed substantial differences in terms of structural variations, rates of substitutions and indels, and transposable element content. For exa...

Our goals were to quantify how non-embolism-inducing pressure gradients influence trunk sapwood specific conductivity (k(s)) and to compare the impacts of constant and varying pressure gradients on k(s) with KCl and H2O as the perfusion solutions. We studied six woody species (three conifers and three angiosperms) which varied in pit membrane structure, pit size and frequency of axial water tra...

Estrogens shape brain circuits during development, and the capacity to synthesize estrogens locally has consequences for both sexual differentiation and the acute modulation of circuits during early learning. A recently optimized method to detect and quantify fluctuations in brain estrogens in vivo provides a direct means to explore how brain estrogen production contributes to both differentiat...

Object-oriented inheritance graphs work well as long as each entity has only one dimension of variation. Sadly, as soon as a second dimension of variation is required, the object-oriented programmer is forced to resort to the visitor pattern, strategy pattern, or an aspect-oriented methodology, each requiring a cumbersome refactoring. In addition to the time spent splitting and refactoring, asp...

We conceptualize personality and individual variation from the perspective of dynamical systems. People s thoughts, feelings, and predispositions for action are inherently dynamic, displaying constant change due to internal mechanisms and external forces, but over time the flow of thought and action converges on a narrow range of states—a fixed-point attractor—that provides cognitive, affective...

Studies that attempt to define facial attractiveness often do so in terms of structural features of the face (e.g., symmetry, averageness). However, these studies typically use static images of faces that may not be analogous to dynamic faces that are frequently used in other areas of attractiveness research, such as research investigating the impact of attractiveness on social interaction. The...

Although fluid resuscitation of patients having acute circulatory failure is essential, avoiding unnecessary administration of fluids in these patients is also important. Fluid responsiveness (FR) is defined as the ability of the left ventricle to increase its stroke volume (SV) in response to fluid administration. The objective of this review is to provide the recent advances in the detection ...

The aqueous mixtures of light gas molecules under low-temperature and high-pressure conditions are candidates to form gas hydrate clathrates. The formation of gas hydrate may lead to various problems and extra charges in natural gas production and processing. The presence of hydrate crystals forming a stable solid phase can potentially block the wells, pipes, and process facilities. To avoid su...

OBJECTIVES : A systematic review of the literature to determine the ability of dynamic changes in arterial waveform-derived variables to predict fluid responsiveness and compare these with static indices of fluid responsiveness. The assessment of a patient's intravascular volume is one of the most difficult tasks in critical care medicine. Conventional static hemodynamic variables have proven u...
