The actual trend of railway industry on track surveying is heading up the development fast automated methods for continuous monitoring quality. This paper presents a model-based methodology estimation lateral and vertical irregularities from different sensors mounted Track Recording Vehicle (TRV): an Inertial Measurement Unit (IMU), gauge sensor position encoder. proposed methodology, based Kal...

Paracellin-1 (PCLN-1) belongs to the claudin family of tight junction proteins and possibly plays a critical role in the reabsorption of magnesium and calcium. So far, the physiological properties of PCLN-1 have not been clarified. In the present study, we investigated whether PCLN-1 is associated with ZO-1. We also investigated whether (45)Ca(2+) transport across the paracellular barrier is af...

In Apr. 2008, commercially purchased processed potato chips were observed with dark brown arcs and rings typical of corky ringspot disease. This disease is caused by infection with tobacco rattle virus (TRV). A portion of RNA 1 of TRV was amplified by reverse transcription polymerase chain reaction (RT-PCR) from each of eight discolored chips from three different bags purchased at three locatio...

PURPOSE To study normative ranges, learning effect (LE), test-retest variability (TRV), and influence of blur and cataract in normal subjects by using rarebit perimetry (RBP). METHODS Seventy-five normal subjects underwent visual field (VF) testing with standard automated perimetry (SAP) and RBP. LE and TRV for RBP were assessed in repeated examinations conducted on four different days. LE wa...

In contrast to the current wealth of structural information concerning dicistrovirus particle structure, very little is known about their morphogenetic pathways. Here, we describe the expression of the two ORFs encoded by the Triatoma virus (TrV) genome. TrV, a member of the Cripavirus genus of the Dicistroviridae family, infects blood-sucking insects belonging to the Triatominae subfamily that...

PURPOSE To investigate changes in the variability of white-on-white perimetry in patients with glaucoma who are undergoing surgical or medical reduction of intraocular pressure (IOP). METHODS This retrospective study included 67 eyes of 50 patients who underwent trabeculectomy (25 eyes) or medical IOP reduction (25 eyes) about midway through the follow-up; 17 fellow eyes of the surgical group...

BACKGROUND Plant cell suspensions and hairy root cultures represent scalable protein expression platforms. Low protein product titers have thus far limited the application of transient protein expression in these hosts. The objective of this work was to overcome this limitation by harnessing A. tumefaciens to deliver replicating and non-replicating RNA viral vectors in plant tissue co-cultures....

PURPOSE To quantify factors affecting test-retest variability of threshold measurements over a series of 3 serial visual fields (VF). DESIGN Prospective comparative observational study. PARTICIPANTS Forty-one normals, 10 suspects and 35 stable glaucoma patients. METHODS All subjects performed 3 standard and 3 short-wavelength automated perimetry (SWAP) VFs. At each VF location, severity (...

Root-knot nematodes (RKNs) are sedentary biotrophic parasites that induce the differentiation of root cells into feeding cells that provide the nematodes with the nutrients necessary for their development. The development of new control methods against RKNs relies greatly on the functional analysis of genes that are crucial for the development of the pathogen or the success of parasitism. In th...
