Antistreptolysin O (ASO) titers were determined on 117 human sera with rabbit, human, and sheep red blood cells (RBC) as the indicator system in the ASO tube test. The titers of 65% of the sera were one dilution step higher when a 5% suspension of sheep RBC was used instead of a 5% suspension of rabbit RBC. Titers were one dilution step higher in 42.7% of the sera when a 5% suspension of human ...

Chronic imaging of cerebral blood flow (CBF) is an important tool for investigating vascular remodeling after injury such as stroke. Although techniques such as Laser Speckle Contrast Imaging (LSCI) have emerged as valuable tools for imaging CBF in acute experiments, their utility for chronic measurements or cross-animal comparisons has been limited. Recently, an extension to LSCI called Multi-...

Red blood cells (RBCs) aggregate in the presence of increased plasma fibrinogen and low shear forces during blood flow. RBC aggregation has been observed in deep vein thrombosis, sepsis and diabetes. We propose using photoacoustics (PA) as a non-invasive imaging modality to detect RBC aggregation. The theoretical and experimental feasibility of PA for detecting and characterizing aggregation wa...

Patients with Polythemia vera (PV) have a high incidence of thrombosis (25-75 %). Vascular complications are responsible of retinopathy, renal failure and coronary disease in diabetes mellitus (DM). Retinal Vascular Vein Occlusion (RVO) is a cause of blindness. To evaluate is red blood cell (RBC) abnormalities may be one vascular risk in these disease we studied RBC adhesion to endothelial cell...

Horse blood has a higher tendency to form red blood cell (RBC) aggregates compared with human blood, with this enhanced aggregation previously attributed to differences in plasma factors. Our results confirm this observation and further indicate that washed horse RBC also have a significantly higher aggregation tendency in dextran 70 solutions (i.e., horse RBC have a higher "aggregability"). In...

Aim This study was aimed to explore the effects of carboxyhemoglobin on reperfusion injury in hemorrhagic shock, as well as its action time and related mechanisms. Results CO-RBC group showed milder oxidative injury than O2-RBC group. CO reperfusion did not show advantages in functions of kidney and lung during resuscitation. The level of Bax was decreased in CO-RBC group, especially in early...

Thiopurine S-methyltransferase (TPMT) plays an important role in the metabolism of thiopurine drugs. In humans, a common genetic polymorphism for TPMT is a major factor responsible for individual variation in the toxicity and therapeutic efficacy of these drugs. Dogs (Canis familiaris) are also treated with thiopurine drugs and, similar to humans, they display large individual variations in thi...

haemoplasmas contain eperythrozoon and haemobartonella species, which are widespread causes of animal and human infections. these obligatory cell parasites were previously known as hemobartonella; now hemotropic mycoplasmas. these bacteria are identified by the lack of cell wall and their small genome. the usual diameter is between 0.3 and1μm. mycoplasmasarepolymorphic and seen in circular or b...

SCOPE We modeled red blood cell (RBC)-folate response to supplementation and developed personalized folate supplementation concepts. METHODS AND RESULTS The changes of RBC-folate were modeled in a time- (4 or 8 weeks) and dose- (400 or 800 μg d-1 folate) dependent manner. Post-supplementation RBC-folate levels were predicted from folate-loading capacities (= measured RBC-folate - [baseline RB...
