We report the feasibility of monitoring both hemoglobin oxygen saturation and hemoglobin concentration in the superficial layer of tissue using polarization-gated elastic light-scattering spectroscopy. We detail our analysis technique, the experimental validation of our analysis, and the detection of an early increase in blood supply to the superficial layer of colon tissue in human patients wi...

Mean corpuscular hemoglobin concentration (MCHC), a parameter that is reported as a part of a standard complete blood count by automated analyzer, is a measure of the concentration of hemoglobin in a given volume of packed red blood cell. Values of MCHC significantly above reference range are not physiologically possible due to limitations on solubility of hemoglobin. The high MCHC can give us ...

Glycation is the nonenzymatic addition of sugar to amino groups of proteins. While virtually any protein in the body can be glycated, for convenience and ease of obtaining a sample, glycated hemoglobin is measured in the blood obtained from a patient. Blood glucose concentrations exhibit wide diurnal fluctuations due to food ingestion, exercise, and other factors. In contrast, the concentration...

Persons with sickle cell anemia who have elevated fetal hemoglobin or lowered erythrocyte mean corpuscular volume are reputed to have less severe clinical manifestations and a greater probability of survival. This study examines the relationship between seven clinical indicators of morbidity in sickle cell anemia and seven hematological parameters that were collected from 214 patients. Risks of...

Background: High maternal hemoglobin (Hb) concentration was considered a risk factor for the developing of pregnancy hypertension. The purpose of this study was to determine whether high maternal Hb concentration in first trimesters associated with pregnancy induced hypertension in Iranian nulliparous women. Methods: This study was carried out in teaching hospital in Sari, Iran. Samples were ob...

Measurement of hemoglobin concentration is among the most common clinical procedures. It is necessary in screening for anemia and is a means of providing a general assessment of physical well-being. Current methods for measuring hemoglobin concentration are invasive, requiring blood access. This paper describes a novel technique for measuring hemoglobin concentration noninvasively. The method t...

Tissue vasculature is altered when cancer develops. Consequently, noninvasive methods of monitoring blood vessel size, density, and oxygenation would be valuable. Simple spectroscopy employing fiber optic probes to measure backscattering can potentially determine hemoglobin parameters. However, heterogeneity of blood distribution, the dependence of the tissue-volume-sampled on scattering and ab...

Background: In natural waters and/or aquaculture facilities, fish are often exposed to chromium waste and demonstrate cumulative deleterious effects. To our knowledge, there are no studies concerning the effects of trivalent Cr on C. carpio hematology. This study presents hematological and some biochemical parameters of common carp, Cyprinus carpio, affected by sublethal concentration of triva...

A small percentage of hemodialysis patients maintain higher hemoglobin concentrations without transfusion or erythropoietic therapy. Because uncertainty exists regarding the effects of higher hemoglobin concentration on mortality and quality of life among hemodialysis patients, studying this group of patients with sufficient endogenous erythropoietin may provide additional insights. The prospec...
