BRD7 improves glucose homeostasis independent of IRS proteins
(Bioscientifica, 2023-09-01)Bromodomain-containing protein 7 (BRD7) has emerged as a player in the regulation of glucose homeostasis. Hepatic BRD7 levels are decreased in obese mice, and the reinstatement of hepatic BRD7 in obese mice has been shown ... -
Diffuse optical tomography to monitor the photocoagulation front during interstitial photothermal therapy: Numerical simulations and measurements in tissue-simulating phantoms
(De Gruyter, 2014-08-06)Near-infrared interstitial photothermal therapy (PTT) is currently undergoing clinical trials as an alternative to watchful waiting or radical treatments in patients with low/intermediate-risk focal prostate cancer. ... -
Effects of capsule on surface diffuse reflectance spectroscopy of the subcapsular parenchyma of a solid organ
(SPIE, the international society for optics and photonics, 2018-07-27)We hypothesize that the capsular optical properties and thickness combined affect how accurate the diffuse reflectance on the surface of a capsular solid organ represents that on the subcapsular parenchyma. Monte Carlo ... -
Flexible nine-channel photodetector probe facilitated intraspinal multisite transcutaneous photobiomodulation therapy dosimetry in cadaver dogs
(SPIE, the international society for optics and photonics, 2018-01-23)Noninvasive photobiomodulation therapy (PBMT) of spinal cord disease remains speculative due to the lack of evidence for whether photobiomodulatory irradiances can be transcutaneously delivered to the spinal cord under a ... -
Freehand diffuse optical spectroscopy imaging for intraoperative identification of major venous and arterial vessels underlying peritoneal fat: An in vivo demonstration in a pig model
(SPIE, the international society for optics and photonics, 2017-10-30)Inadvertent injury to important anatomic structures is a significant risk in minimally invasive surgery (MIS) that potentially requires conversion to an open procedure, which results in increased morbidity and mortality. ... -
Hybrid positron detection and optical coherence tomography system: Design, calibration, and experimental validation with rabbit atherosclerotic models
(SPIE, the international society for optics and photonics, 2005-07-01)We evaluate the performance of our novel hybrid optical coherence tomography (OCT) and scintillating probe, demonstrate simultaneous OCT imaging and scintillating detection, and validate the system using an atherosclerotic ... -
In vivo assessment of diet-induced rat hepatic steatosis development by percutaneous single-fiber spectroscopy detects scattering spectral changes due to fatty infiltration
(SPIE, the international society for optics and photonics, 2015-11-05)This study explores percutaneous single-fiber spectroscopy (SfS) of rat livers undergoing fatty infiltration. Eight test rats were fed a methionine-choline-deficient (MCD) diet, and four control rats were fed a normal diet. ... -
In vivo trans-rectal ultrasound-coupled optical tomography of a transmissible venereal tumor model in the canine pelvic canal
(SPIE, the international society for optics and photonics, 2009-05-01)In vivo trans-rectal near-infrared (NIR) optical tomography was performed concurrently with, albeit reconstructed without spatial a prior of, trans-rectal ultrasound (US) on transmissible venereal tumor (TVT) developed as ... -
Perspective review on solid-organ transplant: Needs in point-of-care optical biomarkers
(SPIE, the international society for optics and photonics, 2018-08-29)Solid-organ transplant is one of the most complex areas of modern medicine involving surgery. There are challenging opportunities in solid-organ transplant, specifically regarding the deficiencies in pathology workflow or ... -
The utility of direct-current as compared to frequency domain measurements in spectrally-constrained diffuse optical tomography toward cancer imaging
(SAGE Publications, 2011-10-01)This work investigates, by means of analytical and simulation studies, the performance of spectrally-constrained image reconstruction in Continuous-Wave or Direct-Current (DC) and Frequency Domain (FD) near-infrared optical ... -
Transrectal ultrasound-integrated spectral optical tomography of hypoxic progression of a regressing tumor in a canine prostate
(SAGE Publications, 2011-12-01)The objective of this study was to evaluate if transrectal optical tomography implemented at three wavelength bands for spectral detection could monitor changes of the hemoglobin oxygen saturation (SₜO₂) in addition to ... -
Trust in and use of COVID-19 information sources differs by health literacy among college students
(MDPI AG, 2023-03-11)People’s health information-seeking behaviors differ by their health literacy levels. This study assessed the relationship between health literacy and college students’ levels of trust in and use of a range of health ...
