Purpose: The large white pig is a useful experimental model to compare in vivo, in vitro and ex vivo sensitivity of peripheral blood leukocytes to ionising radiation. Such studies are impossible to perform in humans and laboratory rodents due to ethical reasons and body size, respectively. We analysed dose- and time-dependent changes of ...

The function of phagocytic and antigen presenting cells is of crucial importance to sustain immune competence against infectious agents as well as malignancies. We here describe a reproducible procedure for the quantification of phagocytosis by leukocytes in whole blood. For this, a pH-sensitive green-fluorescent protein- (GFP) like dye (Eos-FP) is ...

We have demonstrated that it is possible to launch UVC LED light into bacterial contaminated polymer tubes/catheters and disinfect the intraluminal space of these tubes. This can be achieved by UVC treatment of the catheters on a regular basis. Catheters are in the distal end equipped with an exit hole ...

In addition to the issues concerning blood transfusions in general, special considerations apply to transfusing neonates. Young infants' plasma may contain maternal antibodies to ABO blood group antigens instead of the naturally occurring anti-ABO antibodies normally present in older patients. This facilitates the transplant of hearts across ABO boundaries but ...

Threats of nuclear and other radiologic exposures have been increasing, but no countermeasure for acute radiation syndrome has been approved by regulatory authorities. Because of their similarity to humans in regard to physiology and anatomy, we are characterizing Gottingen minipigs as a model to aid the development of radiation countermeasures. ...

To implement a new cost efficacy internal Service for blood component irradiation, we carried out specific procedures and quality assurance reports using the linear accelerators (LINACs) of the Regina Elena Institute (IRE) Radiotherapy Department instead of a dedicated device.

Hyperglycemia and glycemic variabilities are associated with adverse outcomes in critically ill patients. Blood glucose control with insulin mandates an adequate and precise assessment of blood glucose levels. Blood glucose levels, however, can change ex vivo after sampling. The aim of this study was to determine whether this phenomenon affects ...

Postprandial hypotension occurs frequently and is associated with increased morbidity. Gastric distension may attenuate the postprandial fall in blood pressure (BP).

This study explored metabolic mechanisms of future (delay) discounting, a choice phenomenon where people value present goods over future goods. Using fluctuating blood glucose as an index of body-energy budget, optimal discounting should regulate choice among rewards as a function of temporal caloric requirement. We identified this novel link between ...

A calibration model was developed for a noninvasive blood glucose sensor, to determine how the blood glucose data measured by this sensor is related to blood glucose data measured with laboratory capillary finger sticks and to corrupting noise. The variability of calibration models for different patients was analyzed as well ...

In this study, a new portable type Self-Monitoring Blood Glucose (SMBG) device, which is driven automatically from the blood sampling to the blood glucose measurement, is developed to establish the point-of-care technology in the ubiquitous medical care. It aims to overcome human errors due to the complicated manual operation of ...

A convenient method for chemically treating zebrafish is to introduce the reagent into the tank water, where it will be taken up by the fish. However, this method makes it difficult to know how much reagent is absorbed or taken up per fish. Some experimental questions, particularly those related to ...

Blood Glucose (BG) analysis and control in critically ill patients became an important research challenge in the last few years. Despite the big improvements that have been achieved both in research and in clinical practice, there are still many aspects that need to be elucidated. A first step towards a ...

BACKGROUND: Altered blood glucose concentration is commonly observed in patients with sepsis, even among those without hypoglycemic treatments or history of diabetes mellitus. These alterations in blood glucose are potentially detrimental, although the precise relationship with outcome in patients with bacteremia has not been yet determined. METHODS: A retrospective cohort ...

BACKGROUND: Previous studies have found positive bias and frequent outliers when central venous catheter (CVC) whole blood is used to dose glucose meters. We designed a study to determine whether positive bias and outliers with CVC whole blood glucose samples are due to exogenous glucose contamination of CVC samples, inherent ...

DESIGN: Validation study. SAMPLE POPULATION: 92 samples of fresh whole blood and plasma from 83 dogs with various diseases. PROCEDURES: Each PBGM ...

Postprandial blood glucose concentration is a risk factor for the development of cardiovascular diseases and diabetes, even at states well below hyperglycemic levels. A previous study has shown that postmeal exercise of moderate intensity blunts the blood glucose increase after carbohydrate intake (H?stmark et al. Prev. Med. 42(5): 369-371). The ...

BACKGROUND: Tris-hydroxymethyl aminomethane can be used as a buffer in case of restricted ventilation, but hypoglycaemia is one adverse effect. The influence of a starch-based colloid [6% hydroxyethyl starch 130 kDa/0.4 (HES130)] vs. a gelatine-based colloid (4% polysuccinated gelatine) on blood glucose was investigated in a swine model of mixed ...

Blood glucose and non-esterified fatty acid (NEFA) concentrations (often determined in cows to evaluate their energy status) can be influenced by stress. To assess whether the stress of routine handling prior to blood-sampling might influence the systemic concentrations of these compounds, blood samples were taken from two groups of lactating ...

Organohalogen contaminants (OHCs) may affect various physiological parameters in birds including blood chemistry. We therefore examined blood plasma clinical-chemical parameters and OHCs in golden eagle, white-tailed eagle and goshawk chicks from Northern Norway. Correlation analyses on pooled data showed that alkaline phosphatase (ALKP), glucose and creatinine were significantly negatively correlated ...
