BACKGROUND Published analyses of clinical outcomes for patients requiring large-volume blood transfusion conflict with respect to the impact upon plasma potassium levels. We analyzed a cohort of trauma patients to ascertain the impact of component product transfusion upon plasma potassium values. METHODS We performed an observational analysis of previously, prospectively collected clinical da...

Recent observations demonstrate that confluent tissues exhibit features of glassy dynamics, such as caging behavior and dynamical heterogeneities, although it has remained unclear how single-cell properties control this behavior. Here we develop numerical and theoretical models to calculate energy barriers to cell rearrangements, which help govern cell migration in cell monolayers. In contrast ...

OBJECTIVE This study analyzed the factors that are associated with the need for packed red blood cell transfusions in premature infants in a neonatal intensive care unit. METHODS This study is a cross-sectional study of secondary data from premature infants who were admitted to a neonatal intensive care unit between 2008 and 2010. Premature infants with low birth weight were included. Packed ...

The effect of changes in packed cell volume was studied in two commonly used reagent strip methods (Dextrostix and Reflotest) of measuring blood glucose and in a filter paper blood spot method. It was found that the results with both the reagent strip methods were greatly haematocrit-dependent. Attention is drawn to the possibility of false diagnoses of hypoglycaemia in haemoconcentrated patien...

The relationship between alcuronium requirements and the plasma concentration of albumin and total globulin was investigated in 50 adult patients undergoing elective upper abdominal surgery. No significant correlation was obtained with the plasma proteins (g/100 ml plasma). A significant positive correlation between alcuronium requirements and plasma albumin X (1-PCV), especially in anaemic pat...

AIM To evaluate the relative importance of biochemical markers of antioxidant status, gestational age, and parameters of neonatal care in the clinical outcome of premature infants. METHOD A prospective, observational, longitudinal study of the association between these factors was conducted. Blood was collected from an in situ arterial line within two hours of birth and at intervals thereafte...

The precision of concentration sensing is improved when cells communicate. Here we derive the physical limits to concentration sensing for cells that communicate over short distances by directly exchanging small molecules (juxtacrine signaling), or over longer distances by secreting and sensing a diffusive messenger molecule (autocrine signaling). In the latter case, we find that the optimal ce...

Chickens inoculated with a transplantable lymphoid tumor developed a progressive anemia that was classified morpho logically as normochromic and normocytic. The bone marrow showed normal cellularity with no evidence of tumor metastasis, and immature erythrocytes were not detected in the peripheral blood. (Increased serum transferrin was corre lated with a decline in both packed cell volume and ...
