In this paper, we proposed a high data rate, low-power, and large random jitter tolerance wideband signaling (WBS) transceiver for human body channel communication (BCC). At the transmitter part, a spread spectrum clock generator is applied to reduce the electromagnetic emission. Subsequently, the proposed WBS transmitter uses a NRZI encoding scheme to transmit the data. At the receiver part, a...

RATIONALE Analyses of stable carbon isotope ratios (δ13 C values) of organic and inorganic matter remains have been instrumental for much of our understanding of present and past environmental and biological processes. Until recently, the analytical window of such analyses has been limited to samples containing at least several μg of carbon. METHODS Here we present a setup combining laser abl...

The robustness to noise of the 802.11b/g 5.5 Mb/s and 11 Mb/s rates must be investigated experimentally as they cannot be predicted theoretically. In this paper we report on detailed outdoor and indoor measurements that lead us to the surprising conclusion that the 6 Mb/s 802.11g rate experiences more packet loss than the 11 Mb/s 802.11g rate at any given SNR. This occurs due to the combination...

Oxidative stress induced by reactive oxygen and nitrogen species has been implicated in the pathogenesis of various disorders and diseases. Biomarkers are needed for assessment of oxidative stress status in vivo and also for health examination, diagnosis at early stage, prognosis, safe and efficient drug development, and evaluation of efficacy of drugs, foods, beverages, and supplements. Lipids...

BACKGROUND 12/15-lipoxygenase (12/15-LO) activity leads to the production of the proinflammatory eicosanoids 12-S-hydroxyeicosatetraenoic acid (12SHETE) and 13-S-hydroxyoctadecadienoic acid. We have previously shown a 3.5-fold increase in endothelial intercellular adhesion molecule (ICAM)-1 expression in mice overexpressing the 12/15-LO gene. We examined whether 12/15-LO activity regulated endo...

Background/objectives. This study examines the surface activity, resistance to biophysical inhibition, and pulmonary efficacy of a synthetic lung surfactant containing glycerophospholipids combined with Super Mini-B (S-MB) DATK, a novel and stable molecular mimic of lung surfactant protein (SP)-B. The objective of the work is to test whether S-MB DATK synthetic surfactant has favorable biophysi...

Catechol-O-methyltransferase (COMT) has two isoforms: soluble (S-COMT), which resides in the cytoplasm, and membrane-bound (MB-MT), anchored to intracellular membranes. COMT is involved in the O-methylation of L-DOPA, dopamine and other catechols. The exact role of MB-COMT is still mostly unclear. We wanted to create a novel genetically modified mouse model that specifically lacks MB-COMT activ...
