A rapid, cheap and effective method for diagnosing tuberculosis (TB) is essential for TB control. We evaluated the performance of an immunochromatographic assay (ICA) kit (SD Bioline TB Ag MPT64 rapid test) designed for detecting Mycobacterium tuberculosis complex (MTC) in liquid and solid cultures to determine its ability to detect and differentiate MTC directly in sputum samples. We attempted...

the biologists now face with the masses of high dimensional datasets generated from various high-throughput technologies, which are outputs of complex inter-connected biological networks at different levels driven by a number of hidden regulatory signals. so far, many computational and statistical methods such as pca and ica have been employed for computing low-dimensional or hidden representat...

We studied the developmental changes in the beta-adrenergic modulation of L-type calcium current (ICa) in enzymatically isolated adult (AD) and newborn (NB, 1-4-day-old) rabbit ventricular cells using the whole-cell patch-clamp method. ICa was measured as the peak inward current at a test potential of +15 mV by applying a 180-450-msec pulse from a holding potential of -40 mV with Cs(+)-rich pip...

Reef-building corals import inorganic carbon (Ci) to build their calcium carbonate skeletons and to support photosynthesis by the symbiotic algae that reside in their tissue. The internal pathways that deliver Ci for both photosynthesis and calcification are known to involve the enzyme carbonic anhydrase (CA), which interconverts CO2 and HCO3 (-). We have developed a method for absolute quantif...

OBJECTIVE The aim of this study was to determine the prevalence of symmetry, asymmetry and hypoplasia of the intracranial internal carotid artery (ICA), and the possible presence of other variants of the ICA by magnetic resonance angiography (MRA). SUBJECTS AND METHODS This prospective-retrospective study included 1000 subjects who underwent consecutively MRA of the cerebral arteries. 3D-time...

This paper presents a stable and fast algorithm for independent component analysis with reference (ICA-R). This is a technique for incorporating available reference signals into the ICA contrast function so as to form an augmented Lagrangian function under the framework of constrained ICA (cICA). The previous ICA-R algorithm was constructed by solving the optimization problem via a Newton-like ...

OBJECTIVE To conduct a retrospective analysis of inpatients referred for invasive coronary angiography (ICA) at a tertiary centre, with suspected or confirmed acute coronary syndrome (ACS). METHODS A retrospective cohort study was conducted at Jersey General Hospital. We evaluated 198 inpatients referred for ICA with suspected or confirmed ACS over a 3-year period. Patients presenting with ST...

El presente estudio determina la calidad del agua río Guano en Ecuador mediante los índices de ICA-NSF, ICA-Dinius y una variante al índice que incluye pendiente media cause el caudal. Para esta manera obtener valores cualitativos permitan un mejor aprovechamiento río. Los resultados obtenidos con tres ínidces muestran existe contaminación leve ciertos tramos río, provocada por las actividades ...
