Cannabinoid CB(1) receptors are involved in ocular physiology and may regulate intraocular pressure (IOP). However, endocannabinoid levels in human ocular tissues of cornea, iris, ciliary body, retina, and choroid from normal and glaucomatous donors have not been investigated. Anandamide (N-arachidonoylethanolamine; AEA), 2-arachidonoylglycerol (2-AG), and(More)
INTRODUCTION Glaucoma is a multifactorial disease characterized by progressive optic nerve injury and visual field defects. Elevated intraocular pressure (IOP) is the most widely recognized risk factor for the onset and progression of open-angle glaucoma, and IOP-lowering medications comprise the primary treatment strategy. IOP elevation in glaucoma is(More)
The authors studied seizure activity with optical intrinsic signal (OIS) imaging in a rat seizure model. OIS, which measures vascular and metabolic effects associated with neuronal activity, showed significant cortical reflectance changes from penicillin-induced seizures, and correlated well with EEG epileptiform discharges. Furthermore, OIS changes often(More)
Benign hereditary chorea (BHC) recently has been associated with mutations in TITF-1 gene, although a pathological study of an individual with BHC and a TITF-1 mutation revealed no significant gross or microscopic abnormalities using standard methods. Immunohistochemical staining of striatal tissue from a BHC-affected postmortem brain was performed using(More)
Cortical spreading depression (CSD) was imaged in vivo in a rodent model with optical intrinsic signals (OIS). This is the first study to identify a triphasic OIS response and to characterize the rate and timing of the response. The initial OIS phase had a highly uniform wavefront, which spread at a rate characteristic of CSD, 3.5 mm/min. Later phases were(More)
Interleukin (IL)-18 has been well characterized as a costimulatory factor for the induction of IL-12–mediated interferon (IFN)-␥ production by T helper (Th)1 cells, but also can induce IL-4 production and thus facilitate the differentiation of Th2 cells. To determine the mechanisms by which IL-18 might regulate these diametrically distinct immune responses,(More)
In-home healthcare applications that use wearable devices ordinarily have strict power constraints due to the small size of the battery in the device. The power constraints are a key driver of research to develop new methods for improving the energy efficiency of ambulatory health monitoring devices. The radio-communication components typically consume a(More)
Understanding the storage and release of the excitatory neurotransmitter, L-glutamate by synaptic vesicles has lagged behind receptor characterizations due to a lack of pharmacological agents. We report that the glutamate analog, 3-aminoglutarate (3-AG) is a "silent" false transmitter for glutamate neurons that may be a useful tool to study storage and(More)
Breast cancer occurring in women under the age of 40 is uncommon in the absence of family history or genetic predisposition, and prompts the exploration of other possible exposures or environmental risks. We report a case series of four young women-ages from 21 to 39-with multifocal invasive breast cancer that raises the concern of a possible association(More)
