Murray's law revisited: Qu\'emada's fluid model and fractal trees [PDF]

open access: yes, 2015
In 1926, Murray proposed the first law for the optimal design of blood vessels. He minimized the power dissipation arising from the trade-off between fluid circulation and blood maintenance.

Abnormally hyperdense intracranial vessels on non-contrast computed tomography scan simulating dural venous sinus thrombosis in a case with high hematocrit

open access: yesMedical Journal of Dr. D.Y. Patil University, 2013
Abnormal hyperdensity of intracranial blood vessels on non-contrast computed tomography scan (NCCT) may be found in cases with raised hematocrit. This finding not only simulates the appearance of a contrast enhanced CT scan but also may mimic dural ...

The Roles of C-X-C Motif Chemokine Ligand 10 (CXCL10) in Dengue

open access: yesJournal of Pure and Applied Microbiology, 2022
Early diagnosis of dengue is crucial to prevent the progression to severe dengue (SD) leading to mortality rate reduction. This study aimed to determine the role of the CXCL10 in dengue and its potential utilization as one of the biomarkers for the early

Point-of-care versus central testing of hemoglobin during large volume blood transfusion. [PDF]

open access: yes, 2019
BACKGROUND: Point-of-care (POC) hemoglobin testing has the potential to revolutionize massive transfusion strategies. No prior studies have compared POC and central laboratory testing of hemoglobin in patients undergoing massive transfusions. METHODS: We

The Relation Between Capillary Transit Times and Hemoglobin Saturation Heterogeneity. Part 1: Theoretical Models

open access: yesFrontiers in Physiology, 2018
Capillary dysfunction impairs oxygen supply to parenchymal cells and often occurs in Alzheimer's disease, diabetes and aging. Disturbed capillary flow patterns have been shown to limit the efficacy of oxygen extraction and can be quantified using ...

Predictive factors for elevated prostate specific antigen and hematocrit levels during testosterone replacement therapy in patients with testosterone deficiency

open access: yesJournal of Men's Health, 2022
Objective: We examined risk factors associated with prostate specific antigen (PSA) and hematocrit (hct) elevation during testosterone replacement therapy (TRT) in patients with testosterone deficiency (TD).

Why dried blood spots are an ideal tool for CYP1A2 phenotyping [PDF]

open access: yes, 2014
Background and Objective: Dried blood spot (DBS) sampling has gained wide interest in bioanalysis during the last decade and has already been successfully applied in pharmacokinetic and phenotyping studies.

The Body Hematocrit/Venous Hematocrit Ratio and the "Splenic Reservoir" [PDF]

open access: yesBlood, 1961
Abstract 1. Red cell volume and plasma volume were measured by the radioactive sodium chromate and the chromic chloride method respectively in 37 patients. 2. The body hematocrit/venous hematocrit (BH/VH) ratio was found to be constant in normal subjects and in patients in whom there was neither splenomegaly nor edema. The

Increased plasma viscosity as a reason for inappropriate erythropoietin formation [PDF]

open access: yes, 1993
The aim of this study was to examine whether altered plasma viscosity could contribute to the inappropriately low production rate of erythropoietin (EPO) observed in patients suffering from hypergammaglobulinemias associated with multiple myeloma or ...

Venous Hematocrit: Caveats to Informing Blood Volume and Relative Risk in Chronic Heart Failure

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Venous hematocrit (vHct) is commonly used to inform blood volume (BV) status and stratify cardiovascular risk. However, vHct defines a percentage of red blood cells (RBCs) to total BV; therefore, similar vHcts can reflect significantly ...
