We describe a novel and effective video enhancement algorithm for low lighting video. The algorithm works by first inverting the input low-lighting video and then applying an image de-haze algorithm on the inverted input. To facilitate faster computation and improve temporal consistency, correlations between temporally neighboring frames are utilized.(More)
Increased hexosamine biosynthesis pathway (HBP) flux and elevated levels of protein O-linked-N-acetylglucosamine (O-GlcNAc) decrease calcium influx into isolated cardiomyocytes. Increased O-GlcNAc levels also increase tolerance of cells to stress. Therefore, the goal of this study was to test the hypothesis that increasing HBP flux and protein O-GlcNAc(More)
Environmental tobacco smoke (ETS) has been associated with cardiovascular mortality. Pathophysiologic pathways leading from ETS exposure to cardiopulmonary disease are still being explored. Reduced cardiac autonomic function, as measured by heart rate variability (HRV), has been associated with cardiac vulnerability and may represent an important(More)
According to the very limited cancer registry, incidence and mortality rates for female breast cancer in China are regarded to be increasing especially in the metropolitan areas. Representative data on the breast cancer profile of Chinese women and its time trend over years are relatively rare. The aims of the current study are to illustrate the breast(More)
In China, breast cancer is currently the most common malignancy and the sixth leading cause of cancer death in women. But, the characteristics of breast cancer in the whole population are not determined. The aim of this study was to perform a detailed study on pathologic characteristics of breast cancer representing the whole population in China during(More)
In nonexcitable cells, depletion of endoplasmic reticulum Ca(2+) stores leads to activation of plasma membrane Ca(2+) channels, a process termed capacitative Ca(2+) entry. Here, we demonstrate that this pathway functions in cells that also contain voltage-gated Ca(2+) channels, neonatal rat ventricular myocytes. The depletion of sarcoplasmic reticulum(More)
Hyperglycemia alters cardiac function and often leads to diabetic cardiomyopathy as cardiomyocyte apoptosis causes a hypertrophied heart to deteriorate to dilation and failure. Paradoxically, many short-term animal models of hyperglycemia protect against ischemia-induced damage, including apoptosis, by limiting Ca(2+) overload. We have determined that, like(More)
We have designed and synthesized a novel ratiometric fluorescent chemodosimeter MHF-based ESIPT process for specific detection of cysteine among the biological thiols. The probe MHF shows very weak blue fluorescence under UV excitation. Upon addition of cysteine (Cys), the reaction of Cys with MHF induces acrylate hydrolysis, thereby enabling the ESIPT(More)
A bis(benzoxazole) derivative with metal-chelating ligand (DPA), Zinhbo-1, exhibits a large fluorescence turn-on effect (up to 10-fold) upon zinc-binding. The metal chelation enables excited state intramolecular proton transfer (ESIPT), giving an additional emission band in the near-IR region (approximately 710 nm) with a large Stokes shift (ca. 230 nm).
BACKGROUND In most developed countries, breast cancer screening (BCS) is a well-established practice which is widely accepted by women. In contrast, national BCS projects in China were only launched in the last two years, so little is known about their public response. METHODS We surveyed 1,162 Chinese women from different socio-economic regions in(More)
