Establishing dry weight in hemodialysis patients is an inexact science.1 Monitoring changes in blood pressure with volume removal is crude but can be effective in establishing dry weight. Unfortunately, probing for dry weight (eg, reduction of volume on dialysis sufficient to reduce blood pressure to 140/90 mm Hg) can lead to intradialytic hypotension, and this is more common in patients with l...

BACKGROUND Staged palliative surgery markedly shifts the balance of volume load on a single ventricle and pulmonary vascular bed. Blalock-Taussig shunt necessitates a single ventricle eject blood to both the systemic and pulmonary circulation. On the contrary, bidirectional cavopulmonary shunt release the single ventricle from pulmonary circulation. CASE PRESENTATION We report a case of tricu...

Aims: Umbilical cord blood (UCB) has been recently considered as an alternative source of hematopoitic progenitor cells for clinical application. The parameters commonly used to evaluate a UCB unit and predict transplant outcomes have been total nucleated cell count (TNCs), CD34+ cells concentration and total volume of cord blood collected. The volume of cord blood collection is also important ...

BACKGROUND Calculation of desired whole blood transfusion volume relies on an estimate of an animal's circulating blood volume, generally accepted to be 0.08 L/kg or 8% of the animal's body weight in kilograms. OBJECTIVE To use packed cell volume before and after whole blood transfusion to evaluate the accuracy of a commonly used equation to predict packed cell volume after transfusion in sma...

throughout the world, millions of muslims fast daily during the month of ramadan from sunrise (sahar) until sunset (iftar). considering the impacts of environment on physiological functions, we performed this study in order to examine the effects of ramadan fasting on some blood parameters of healthy volunteers and hypertensive patients. according to the results, there were no significant chang...

the human blood basal glucose level is a completely controlled range. information on the relationship between culture glucose concentration and changes in the cell's surface area, volume and surface area to volume (s/v) ratio are lacking. cancerous epithelial-like cell lines sw480, sw742 and t-47d were cultured in mediums nourished with 4.7 mm per liter of glucose as the control group and three...

Using Monte Carlo simulations for a semi-infinite medium representing a skeletal muscle tissue, it is demonstrated that the zero- and first-order moments of the power spectrum for a representative pixel of a full-field laser-Doppler imager behave differently from classical laser-Doppler flowmetry. In particular, the zero-order moment has a very low sensitivity to tissue blood volume changes, an...

BACKGROUND No noninvasive technique is currently capable of "real-time" assessment and monitoring of cerebral blood flow (CBF). We hypothesized that cerebral perfusion could be accurately measured and monitored in "real time" with contrast-enhanced ultrasound (CEU). METHODS AND RESULTS Cerebral perfusion was assessed in 9 dogs through a craniotomy with CEU at baseline and during hypercapnia a...
