Arthroscopic Superior Capsule Reconstruction Can Eliminate Pseudoparalysis in Patients With Irreparable Rotator Cuff Tears

Abstract: Background:Patients with pseudoparalysis and irreparable rotator cuff tears have very poor function. The authors developed a superior capsule reconstruction (SCR) technique for irreparable rotator ...

A highly sensitive ethanol sensor based on mesoporous ZnO-SnO2 nanofibers.

Abstract: A facile and versatile method for the large-scale synthesis of sensitive mesoporous ZnO–SnO2 (m-Z–S) nanofibers through a combination of surfactant-directed assembly and an electrospinning approach is reported. The morphology and the structure were investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), x-ray diffraction (XRD), and nitrogen adsorption–desorption isotherm analysis. The results showed that the diameters of fibers ranged from 100 to 150 nm with mixed structures of wurtzite (ZnO) and rutile (SnO2), and a mesoporous structure was observed in the m-Z–S nanofibers. The sensor performance of the prepared m-Z–S nanofibers was measured for ethanol. It is found that the mesoporous fiber film obtained exhibited excellent ethanol sensing properties, such as high sensitivity, quick response and recovery, good reproducibility, and linearity in the range 3–500 ppm.

Stem cell treatment for patients with autoimmune disease by systemic infusion of culture-expanded autologous adipose tissue derived mesenchymal stem cells.

Abstract: Prolonged life expectancy, life style and environmental changes have caused a changing disease pattern in developed countries towards an increase of degenerative and autoimmune diseases. Stem cells have become a promising tool for their treatment by promoting tissue repair and protection from immune-attack associated damage. Patient-derived autologous stem cells present a safe option for this treatment since these will not induce immune rejection and thus multiple treatments are possible without any risk for allogenic sensitization, which may arise from allogenic stem cell transplantations. Here we report the outcome of treatments with culture expanded human adipose-derived mesenchymal stem cells (hAdMSCs) of 10 patients with autoimmune associated tissue damage and exhausted therapeutic options, including autoimmune hearing loss, multiple sclerosis, polymyotitis, atopic dermatitis and rheumatoid arthritis. For treatment, we developed a standardized culture-expansion protocol for hAdMSCs from minimal amounts of fat tissue, providing sufficient number of cells for repetitive injections. High expansion efficiencies were routinely achieved from autoimmune patients and from elderly donors without measurable loss in safety profile, genetic stability, vitality and differentiation potency, migration and homing characteristics. Although the conclusions that can be drawn from the compassionate use treatments in terms of therapeutic efficacy are only preliminary, the data provide convincing evidence for safety and therapeutic properties of systemically administered AdMSC in human patients with no other treatment options. The authors believe that ex-vivo-expanded autologous AdMSCs provide a promising alternative for treating autoimmune diseases. Further clinical studies are needed that take into account the results obtained from case studies as those presented here.

The effects of cold therapy in the postoperative management of pain in patients undergoing anterior cruciate ligament reconstruction.

Abstract: This prospective study assessed 54 consecutive arthroscopically assisted ACL reconstructions for the amount of postoperative pain relief provided by cold therapy, using the Hot/Ice Thermal Blanket. Twenty-six randomly selected patients undergoing this procedure were compared to a control group consisting of 28 patients having the identical procedure in which the Hot/Ice unit was not used postoperatively. The initial ACL injury in both groups was sports related with the exception of three patients whose injury occurred while on the job. The Hot/Ice Thermal Blanket consists of two rubber pads (blankets) connected by a hose to the main cooling unit. The pads were applied to either side of the operated knee in the operative suite. The pads received fluid which was circulated from the main unit. The temperature of the fluid was set at 50 degrees in the recovery room and the unit was run continuously until the time of discharge, which was approximately 4 days. Hot/Ice patients required 53% less injectable Demerol and 67% less oral Vistaril than patients in the control group. Hot/Ice patients had made the conversion from injectable to oral pain medication an average of 1.2 days sooner than did their non-Hot/Ice counterparts. There was no appreciable difference in length of hospital stay. Physical therapy and nursing records documented a greater percentage of compliant patients in the Hot/Ice group. According to these records the Hot/Ice patients were more helpful in self-assistance, were out of bed and ambulating in the halls more quickly, and did their range of motion exercises with greater ease.(ABSTRACT TRUNCATED AT 250 WORDS)

“Yes We Can”: How Online Viewership, Blog Discussion, Campaign Statements, and Mainstream Media Coverage Produced a Viral Video Phenomenon

Abstract: “Viral videos”—online video clips that gain widespread popularity when they are passed from person to person via e-mail, instant messages, and media-sharing Web sites—can exert a strong influence on election campaigns. Unfortunately, there has been almost no systematic empirical research on the factors that lead viral videos to spread across the Internet and permeate into the dominant political discourse. This article provides an initial assessment of the complex relationships that drive viral political videos by examining the interplay between audience size, blog discussion, campaign statements, and mainstream media coverage of the most popular online political video of the 2008 campaign—will.i.am's “Yes We Can” music video. Using vector autoregression, I find strong evidence that the relationship between these variables is complex and multidirectional. More specifically, I argue that bloggers and members of the Obama campaign played crucial roles in convincing people to watch the video and in a...
