deoxyhemoglobin

01/01/2011 - "In 26 malignant tumors of 0.6-2.5 cm in size, Hb(T) was significantly greater than that in the fibroglandular tissue of the same breast (P = .0062). "
01/01/1994 - "Differences between the two methods may be particularly significant for studies of tumors where large concentrations of deoxyhemoglobin and other paramagnetic substances may cause significant susceptibility gradients. "
05/01/2012 - "In vivo tumor-to-normal contrast was greater than ∼1.5 in reduced scattering coefficient for all wavelengths and was ∼1.3 for the tissue concentration of deoxyhemoglobin (ctHb). "
05/01/2012 - "Simultaneous imaging of a targeted fluorescent agent and oxy- and deoxyhemoglobin gave functional information about tumor vasculature in addition to the related agent uptake. "
01/01/2011 - "The malignant tumors and benign lesions demonstrated different Hb(T) and scattering contrasts, which can potentially be exploited to reduce the false-positive rate of conventional mammography and unnecessary biopsies."

04/01/1998 - "Near infrared spectroscopy (NIRS) separated reactive hyperemia into two phases according to the tissue level of deoxyhemoglobin and deoxymyoglobin (tHb+Mb): (1) an early phase during which the tHb+Mb level was supranormal, reflecting enhanced O2 extraction; and (2) a late phase during which the tHb+Mb level was below baseline, reflecting decreased O2 extraction and increased tissue O2 availability. "
03/01/1990 - "Conversely, a low-dose dopamine infusion had no effect on cerebral hemodynamics, but high-dose decreased blood pressure and cerebral oxyhemoglobin, and increased deoxyhemoglobin without appreciable changes in cerebral blood flow, which suggests venous congestion and arterial blood reduction in the brain."
03/01/2004 - "The changes in relative concentration of oxyhemoglobin and deoxyhemoglobin in the cutaneous microvasculature were assessed at rest, during limb elevation, dependency, and cuff-mediated reactive hyperemia for the forearm of 25 normal subjects and 105 feet of patients with peripheral arterial occlusive disease (PAOD) (normal=28, claudication=34, limb threatening ischemia=44). "
01/01/2010 - "TRS demonstrated a decrease of oxyhemoglobin, total hemoglobin, and oxygen saturation associated with an increase of deoxyhemoglobin in all of the regions measured just after embolization, indicating that embolization improved hyperemia caused by the AV shunt. "
01/01/2000 - "Using in vivo validations, we demonstrate 1) expected oxygenation changes during ischemia and reactive hyperemia, 2) expected oxygenation changes during muscle exercise, 3) a close correlation between changes in oxyhemoglobin and oxymyoglobin and changes in deoxyhemoglobin and deoxymyoglobin and limb volume by venous occlusion plethysmography, and 4) a minimal contribution from movement artifact on the detected signals. "

12/21/2009 - "We found the best hemoglobin correlations were when ratios at isosbestic points of oxy- and deoxyhemoglobin were used, specifically 529/500 nm. Baseline subtraction improved correlations, specifically at 520/509 nm. These results demonstrate proof-of-concept for the ability of this noninvasive device to monitor hemoglobin concentration changes due to surgical blood loss. "

10/01/2010 - "The collected data was distributed according to age, sex, and prakruti, and a t-test was applied for the clinical assessment of the subjective and objective parameters of 'Amrita Ghrita,' and it has shown significant reduction in the positivity of the RA titer (t > 5.09, at the 0.001% level), ASO titer (t > 4.08, at the 0.001% level), and CRP titer (t > 4.82, at the 0.001% level), and weight gain (t > 5.12, at the 0.001% level), as also an increase in Hb% (t >9.22, at the 0.001% level), and platelet count (t> 5.90, at the 0.001% level), and decrease in ESR (t > 9.70, at the 0.001% level)."

01/01/2011 - "SWI has improved the diagnosis of microbleeds, brain tumor, cerebrovascular disease, degenerative disease, etc. SWI is superior to GRE T2*-weighted imaging for determining hemosiderin, methohemoglobin, and deoxyhemoglobin contents. "
