We obtain a class of higher-degree stochastic integration filters (SIF) for nonlinear filtering applications. SIF are based on stochastic spherical-radial integration rules that achieve asymptotically exact evaluations of Gaussian weighted multivariate integrals found in nonlinear Bayesian filtering. The superiority of the proposed scheme is demonstrated by comparing the performance of the prop...

This study was designed to demonstrate the characteristic pattern of angiotensin II-induced JAK/STAT (indicating just another kinase/signal transducer and activator of transcription) activation in cultured rat cardiomyocytes by comparing it with leukemia inhibitory factor (LIF)-induced activation. Angiotensin II (10(-7) mol/L) induced rapid phosphorylation of JAK2 and Tyk2, but not JAK1, and ph...

A major role of local acidosis in long lasting excitation and sensitization of cutaneous nociceptors has recently been demonstrated. In inflamed tissue, acid pH meets with a mixture of inflammatory mediators which, by themselves, stimulate nociceptors though being subject to profound tachyphylaxis. We have mimicked this condition in a rat skin-saphenous nerve preparation in vitro which allows d...

The mudpuppy cardiac ganglion contains 2 neuron types: large parasympathetic postganglionic projection neurons and smaller intrinsic neurons originally described by McMahan and Purves (1976) as intensely fluorescent (SIF) cells. The function of these SIF cells, present in the mudpuppy cardiac ganglion, is unknown. Further, direct application of catecholamines, which are thought to be contained ...

Information on the comparative digestibility of food allergens and non-allergenic proteins is crucial when stability to digestion is to be used as a criterion to assess the allergenic potential of novel proteins. Preheating effect on in vitro digestibility has not been fully examined. In this study we investigated the preheating effect of in vitro digestibility of several proteins and their pro...

BACKGROUND Vancouver, Canada has a pilot supervised injecting facility (SIF), where individuals can inject pre-obtained drugs under the supervision of medical staff. There has been concern that the program may facilitate ongoing drug use and delay entry into addiction treatment. METHODS We used Cox regression to examine factors associated with the time to the cessation of injecting, for a min...

BACKGROUND The spontaneous osteoporotic fracture of the sacrum, known as a sacral insufficiency fracture (SIF) was first described as an unrecognized syndrome of the elderly by Laurie, in 1982. Numerous case histories and a few series of cases have been discussed in medical journals; however, none have been reported in Hungary. GOAL To delineate the leading diagnostic steps in the recognition...

OBJECTIVE Sacral insufficiency fracture (SIF) contributes to severe low back pain. Prolonged immobilization resulting from SIF can cause significant complications in the elderly. Sacroplasty, a treatment similar to vertebroplasty, has recently been introduced for providing pain relief in SIF. The purpose of this study is to investigate the clinical short-term effects of percutaneous sacroplasty...

Global retrievals of near-infrared sun-induced chlorophyll fluorescence (SIF) have been achieved in the last few years by means of a number of space-borne atmospheric spectrometers. Here, we present a new retrieval method for medium spectral resolution instruments such as the Global Ozone Monitoring Experiment-2 (GOME-2) and the SCanning Imaging Absorption SpectroMeter for Atmospheric CHartogra...

BACKGROUND North America's first medically supervised safer injection facility (SIF) for illicit drug users was opened in Vancouver, Canada on 22 September 2003. We examined the prevalence and correlates of hepatitis C (HCV) infection among a representative cohort of SIF users. METHODS Users of the Vancouver SIF were selected at random and asked to enrol in the Scientific Evaluation of Superv...
