The progression of subclinical atherosclerosis in SLE and RA has not been comparatively assessed. We sought to investigate the impact of low disease activity and other disease-related factors on atherosclerosis progression in SLE vs RA.
Chronic hepatitis C virus (HCV) infection associated liver disease is a global health problem. HCV often causes silent disease, and eventually progresses to end stage liver disease. HCV infects hepatocytes, however initial manifestation of liver disease is mostly displayed in hepatic stellate cells causing fibrosis/cirrhosis, and believed to be occurring from inflammation in the liver. It is still...
Polyomavirus-associated nephropathy is associated with high risk of kidney allograft loss. Whether the cause of native end-stage renal disease influences the risk of BK infection is unclear.
Vascular pathology is increasingly acknowledged as a risk factor of multiple sclerosis (MS). Vascular density (VD) is reduced in MS patients' eyes on optical coherence tomography (OCT) angiography (A).
The new National Institute on Aging and the Alzheimer's Association Research Framework for Alzheimer's disease has been developed to accelerate drug discovery and offer a common structure and language to construct new Alzheimer's disease conceptual models. However, as a "complex" disease, a model based on systems-level understanding is needed to accommodate the complex, interacting etiologic pathw...
Systemic lupus erythematodes (SLE) represents an autoimmune disease with a highly variable clinical course affecting numerous organs. Hepatic manifestation seems to be rare. It is not clear whether hepatic disease in SLE is of any prognostic importance or whether it correlates with disease activity.
Fabry disease is a X-linked disease, and enzyme-based screening methods are not suitable for female patients.
To see color, the human visual system combines the response of three types of cone cells in the retina-a compressive process that discards a significant amount of spectral information. Here, we present designs based on thin-film optical filters with the goal of enhancing human color vision by breaking its inherent binocular redundancy, providing different spectral content to each eye. We fabricate...
An interesting van der Waals material, TaNiSe has been known one of strong excitonic insulator candidates since it has very small or zero bandgap and can have a strong exciton binding energy because of its quasi-one-dimensional crystal structure. Here we investigate a single crystal TaNiSe using optical spectroscopy. TaNiSe has quasi-one-dimensional chains along the a-axis. We have obtained anisot...
To report patients with sellar tumors and chiasmal compression with normal visual fields, who demonstrate damage to the retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC) on optical coherence tomography (OCT).
Orbital venous malformation (OVM) is a congenital vascular disease. As a common type of vascular malformation in the orbit, OVM may result in vision deterioration and cosmetic defect. Classification of orbital vascular malformations, especially OVMs, is carried out on the basis of different categories, such as angiogenesis, hemodynamics, and locations. Management of OVM is complicated and challeng...
To determine whether vision impairment is independently associated cross-sectionally and longitudinally with dementia.
Optical properties of the rat head tissues (brain cortex, cranial bone and scalp skin) are assessed, aiming at transcranial light applications such as optical imaging and phototherapy. The spectral measurements are carried out over the wide spectral range of 350-2800 nm, involving visible, near-infrared (NIR) and short-wave infrared (SWIR) regions. Four tissue transparency windows are considered: ...
In vivo imaging of tissue/vasculature oxygen saturation levels is of prime interest in many clinical applications. To this end, the feasibility of combining two distinct and complementary imaging modalities is investigated: optoacoustics (OA) and near-infrared optical tomography (NIROT), both operating non-invasively in reflection mode. Experiments were conducted on two optically heterogeneous pha...
Recurrent respiratory papillomatosis (RRP) is a viral-induced disease caused by human papillomavirus and the second leading cause of dysphonia in children; however, neither a cure nor a definitive surgical treatment is currently available for RRP. Although laser therapy is often used in the treatment of RRP, the lack of real-time laser-tissue interaction feedback undermines the ability of physicia...
Clinicians would benefit from knowing the association of glaucomatous change in 2 eyes of the same patient.
Drug delivery by intravitreal injection remains problematic, small agents and macromolecules both clearing rapidly. Typical carriers use microparticles (>2 μm), with size-related liabilities, to slow diffusion. We recently described cationic nanoparticles (NP) where conjugated Arg peptides prolonged residence in rat eyes, through ionic interaction with vitreal poly-anions. Here we extended this s...
We sought to determine the role and retinal cellular location of microRNA-124 (miR-124) in a neuroinflammatory model of retinal degeneration. Further, we explored the anti-inflammatory relationship of miR-124 with a predicted messenger RNA (mRNA) binding partner, chemokine (C-C motif) ligand 2 (Ccl2), which is crucially involved in inflammatory cell recruitment in the damaged retina.
To detect the retinal microvascular impairment using optical coherence tomography angiography (OCT-A) in patients with Parkinson's disease (PD) and find a correlation between the microvascular impairment and the neuronal damage.
