Light on abnormal red blood cell subpopulations: Label-free optics-based approach for studying in vitro rigidified blood cells.

RBCs deformability plays a crucial role in maintaining proper blood flow and oxygen delivery throughout the body. Conventional ektacytometry fails to differentiate between variations in deformability of RBC subpopulations as the averaging measurement process obscures these differences. In this study, we introduced an approach that integrates label-free optics-based techniques (flow cytometry, phase-contrast, and two-photon excitation fluorescent microscopy) with ektacytometry to evaluate subpopulations that exhibit decreased RBCs deformability upon an in vitro oxidation using 0.

Long term false positive hsTnI on Alinity I probably caused by macrotroponin complex: Case report.

Elevated troponin levels are often indicative of various cardiac diseases; however, analytical interference can lead to false positive troponin concentrations. We present the case of a 48-year-old female patient with persistently falsely elevated high sensitivity troponin I (hsTnI) probably caused by the presence of macrotroponin. Laboratory testing included determination of hsTnI using various analytical methods, serial dilutions and determination of heterophilic antibodies and other autoimmune antibodies.

The intensity of subacute local biological effects after the implantation of ALBO-OS dental material based on hydroxyapatite and poly(lactide-co-glycolide): evaluation in rats.

Objectives: This study aimed to evaluate the intensity of the subacute local biological effects after implantation and osseoconductive potential of novel hydroxyapatite-based bone substitute coated with poly (lactide-co-glycolide), named ALBO-OS, in comparison to Bio-Oss.

Methods: Fifteen male Wistar rats, randomly assigned into groups: 10, 20, and 30 days (n꞊5), were subcutaneously implanted with ALBO-OS and Bio-Oss. Furthermore, artificially made bone defects on both rat's tibias were implanted with experimental materials.

An Algorithm for Soft Sensor Development for a Class of Processes with Distinct Operating Conditions.

Soft sensors are increasingly being used to provide important information about production processes that is otherwise only available through off-line laboratory analysis. However, usually, they are developed for a specific application, for which thorough process analysis is performed to provide information for the appropriate selection of model type and model structure. Wide industrial application of soft sensors, however, requires a method for soft sensor development that has a high level of automatism and is applicable to a significant number of industrial processes.
