SUMMARY AVA (Array Visual Analyzer) is a Java program that provides a graphical environment for visualization and analysis of gene expression microarray data. Together with its interactive visualization tools and a variety of built-in data analysis and filtration methods, AVA effectively integrates microarray data normalization, quality assessment, and data mining into one application. AVAILA...

We analyze the amplitude variation as a function of reflection angle (AVA) for angle-domain common image gathers (ADCIG) produced via wave-equation migration. Straightforward implementations of the two main ADCIG methods lead to contradictory, thus inaccurate, amplitude responses. The amplitude inaccuracy is related to the fact that downward-continuation migration is the adjoint of upward-conti...

BACKGROUND To evaluate the efficacy and safety of topical isopropyl unoprostone (IU) in treating macular atrophy in age-related macular degeneration (AMD) patients. METHODS Fifty-two AMD patients with macular atrophy were included and randomly assigned (1:1) to the treatment (topical 0.15% IU) or placebo group. Subjects used study eye drops 3 times a day for 54 weeks. The macular atrophy was ...

Methods 24 post-operative cardiac patients were prospectively enrolled. Arterial pressure and central venous pressure was measured invasively. Cardiac output (CO) was measured with a non-calibrated LiDCOplus monitor (LiDCO, Cambridge). Pmsf was measured using the stop-flow arterial venous equilibrium pressure method (1). Sublingual microcirculation was recorded with CytoCam (Braedius Medical, A...

BACKGROUND Physicians utilize different types of information to predict patient prognosis. For example: confronted with a new patient suffering from severe aortic stenosis (AS), the cardiologist considers not only the severity of the AS but also patient characteristics, medical history, and markers such as BNP. Intuitively, doctors adjust their prediction of prognosis over time, with the change...

Migration of seismic reflection data to common image-point gathers is an integral part of both migration velocity analysis (MVA) and amplitude (AVA) analysis. Its applicability in complex geology depends on whether these gathers will be artifact free, and is related to the formation of caustics and turning ‘rays’ due to the heterogeneity of the velocity model used. Here, we discuss an angle tra...

Bazex-Dupre-Christol (BDC) syndrome is clinically characterizedby multiple basal cell carcinomas of the face that mainly occurduring the second and third decade of life, follicular atrophodermapredominantly of the dorsum sides of the hands and feetand generalized hypotrichosis; sometimes with pili torti andtrichorrhexis nodosa. Features commonly associated with BDCare milia, hypohidrosis and ca...

Optogenetic approaches using light-activated proteins like Channelrhodopsin-2 (ChR2) enable investigating the function of populations of neurons in live Caenorhabditis elegans (and other) animals, as ChR2 expression can be targeted to these cells using specific promoters. Sub-populations of these neurons, or even single cells, can be further addressed by restricting the illumination to the cell...

SOURCE/DESCRIPTION A family of G-specific genes vhose expression is negatively regulated by serum and growth factor has been called gas (growth-arrest-spp.cif lc genes). A fragment of 1.3 Kb of gas-1 cDNA cloned in a EcoRI site of Blue script vector vas used as probe. POLYMORPHISM After DNA digestion with Ava I a constant band of 4.9 Kb and a variant band of 5.4 Kb were observed. FREQUENCY The ...
