Reversal of atrial fibrosis has been proposed as therapeutic strategy to suppress AF. To test the ability of relaxin to reverse aged-dependent atrial fibrosis and suppress AF. Aged F-344 rats (24-months old) were treated with subcutaneous infusion of vehicle or relaxin (0.4 mg/kg/day) for 2-weeks. Rat hearts were excised, perfused on a Langendorff apparatus and stained with voltage and Ca(2+) indicator dyes. Optical mapping and programmed electrical stimulation was used to test arrhythmia vulnerability and changes in electrophysiological characteristics. Changes in protein expression and Na(+)-current density (INa) were measured by tissue immunofluorescence and whole-cell patch clamp technique. In aged rats, sustained AF was readily induced with a premature pulse (n=7/8) and relaxin treatment suppressed sustained AF by...

This paper is mainly concerned on utilities of smart cards in procuring railway tickets. Looking at the history, when the first railway opened, tickets were simply slips of paper with all the details written in by hand. Then, a more efficient system that consisted of small pieces of card, each pre printed with the entire journey details and stored in racks. Then, to speed up ticket issue would be to have a ticket machine in the counter. Tickets would be printed on demand and so reduce the number of tickets held in stock. But, "There is always a great rush at ticket counters. Whether local or long distance trains, the queue is maximum for unreserved tickets. In such traffic conditions, there exists a problem that clerks must be assigned at ticket windows at all times, thus resulting in an increase in labor cost". With these two issues in mind, it is the primary...

At the SRRC, we have previously developed antimicrobial silversodium-carboxymethylated (CM)-cotton printcloth from the sodium salt of CM-cotton, and silver-Ca-Na alginates from four commercially available alginate moist wound dressings. As part of ongoing research on silver antimicrobials, this report delineates the swellabilty of these silver antimicrobial dressings compared to commercially available calciumsodium alginate dressings and printcloth (controls) in water and in 0.9% sodium chloride solution (saline) after 8 hours and after one week of immersion. Additionally, the swelling characteristics are correlated with the absorption of saline g/g of the dressing. Silver treated Sorbsan, Kaltostat, Curasorb, Algisite, and cotton-CM-printcloth showed a very significant increase in diameter of the fibers: NaCl 8 hr > water 8 hr > dry, albeit slightly less than the control alginate dressings. The majority of the swelling took place in the first eight hours of wetting, and continued wetting for one week caused little additional uptake of the solution. Fibers swell only in diameter and not in length. All the fibers had greater swelling in saline as compared with those in water. The proven swellabilty of these silver dressings, taken together with the known absorptive and antimicrobial properties of the dressings should make them suitable for treatment of exudative wounds that are at risk for infection. As more is learned about these dressings, clinical trials may be warranted to evaluate their efficacy.

From the results it is clear that, the BER shift in case of DCT-Based OFDM is less as compared to FFT-Based OFDM. In addition to this we have also compare the BER performance of FFT-Based & DCT-Based OFDM over Additive White Gaussian Noise environment and Multipath Rayleigh Fading environment and it is observed that Bit Error Rate performance of FFT-Based & DCT-Based OFDM over AWGN is better than Multipath Rayleigh Fading environment.

The input to the tool is a circuit description that includes the chips used and their characteristics, the relation between major input and output ports on the chip, and the connectivity information between the chips. The tool analyzes the information and computes testability figure of merits for all parts of the design. These numbers are used to characterize the testability impact of various Design for Test (DFT) solutions and to understand the global effects of local DFT changes. The paper also outlines various applications of the tool

PVR offers diagnostic utility in calcified vessels for which ABI may not be accurate. While many studies have described the association between ABI and extent of CAD, there are no data examining the association between PVR and CAD or the utility of PVR beyond ABI measurements.

A 63-year-old male had an unsuccessful endovascular repair of an aortic anastomotic pseudoaneurysm that left an expanded, uncovered Palmaz stent lying obliquely within the aorta. After nearly 3 years, the pseudoaneurysm enlarged to 7 cm, and the patient became symptomatic. Repair of the pseudoaneurysm was accomplished by crushing the indwelling stent to allow placement of a stent-graft. Malpositioned stents that are hindering an endoluminal procedure may be crushed against the arterial wall in vivo to facilitate passage of endovascular instruments or devices.

The automation of conceptual design practices will decrease design and manufacturing risks by allowing system designers to view the entire performance design space early in the design cycle prior to the initiation of traditional physical design activities.
