BACKGROUND AND AIMS: Disruption of atherosclerotic plaque and distal embolism often cause peri-procedural myocardial injury during percutaneous coronary intervention (PCI). In the present study, we evaluate the association between the characteristics of the target lesion and the amount of debris captured by the filter-type distal protection device. METHODS: We enrolled 120 consecutive patients with acute coronary syndrome, who underwent coronary stent implantation with a filter-type distal protection device after integrated backscatter intravascular ultrasound (IB-IVUS) analysis...

Recovery of vegetation on a Long Island, NY salt marsh was investigated after the removal of hurricane-deposited large wooden debris through managed clean-ups involving volunteers. Two years after the removal of the debris, vegetation cover and species composition were not significantly different from controls. There was no significant difference in vegetation recovery among fall and spring debris removal treatments. Initial vegetation cover of the experimental and control plots was 95.8% and 1.2%, respectively; after two growing seasons cover was 78...

During development of adenovirus-based vaccines, samples have to be analyzed in order to either monitor the production process or control the quality and safety of the product. An important quality attribute is the total concentration of intact adenoviruses, which currently is determined by quantitative polymerase chain reaction (qPCR) or anion exchange-HPLC. Capillary Electrophoresis (CE) was evaluated as alternative to the current methods with the aim to have one single method that allows reliable and fast quantification of adenovirus particles throughout the full process...

: Many goals in tissue engineering rely on modulating cellular localization and polarization of cell signaling, including the inhibition of inflammatory infiltrate, facilitation of inflammatory cell egress, and clearance of apoptotic cells. Omega-3 polyunsaturated fatty acid-derived resolvins are gaining increasing recognition for their essential roles in inhibition of neutrophil invasion into inflamed tissue and promotion of macrophage phagocytosis of cellular debris as well as their egress to the lymphatics...

Infections due to Cryptococcus are a leading cause of fungal infections worldwide and are acquired as a result of environmental exposure to desiccated yeast or spores. The ability of Cryptococcus to grow, mate, and produce infectious propagules in association with plants is important for the maintenance of the genetic diversity and virulence factors important for infection of animals and humans. In the Western United States and Canada, Cryptococcus has been associated with conifers and tree species other than Eucalyptus; however, to date Cryptococcus has only been studied on live Arabidopsis thaliana, Eucalyptus sp...

BACKGROUND: Silicone rod is a commonly used synthetic suspension material in frontalis suspension surgery to correct blepharoptosis. The most challenging problem and a decisive drawback of the use of silicone rod is a considerable rate of ptosis recurrence after surgery. We examined patients with recurred ptosis and assessed the physical and micromorphological properties of implanted silicone rods to determine the causative mechanisms of recurred ptosis after frontalis suspension using silicone rod...

During the last glacial period, the Laurentide Ice Sheet sporadically discharged huge numbers of icebergs through the Hudson Strait into the North Atlantic Ocean, leaving behind distinct layers of ice-rafted debris in the ocean sediments. Perplexingly, these massive discharge events-Heinrich events-occurred during the cold portion of millennial-scale climate oscillations called Dansgaard-Oeschger cycles. This is in contrast to the expectation that ice sheets expand in colder climates and shrink in warmer climates...

Marine debris (MDs) produces a wide variety of negative environmental, economic, safety, health and cultural impacts. Most marine litter has a very low decomposition rate (plastics), leading to a gradual accumulation in the coastal and marine environment. Characterization of the MDs has been done in terms of their pollutant content: PAHs, ClBzs, ClPhs, BrPhs, PCDD/Fs and PCBs. The results show that MDs is not a very contaminated waste. Also, thermal decomposition of MDs materials has been studied in a thermobalance at different atmospheres and heating rates...

Marine debris is a management issue with ecological and recreational impacts for agencies, especially on remote beaches not accessible by road. This project was implemented to remove and document marine debris from five coastal National Park Service units in Alaska. Approximately 80km of coastline were cleaned with over 10,000kg of debris collected. Marine debris was found at all 28 beaches surveyed. Hard plastics were found on every beach and foam was found at every beach except one. Rope/netting was the next most commonly found category, present at 23 beaches...

Bilateral lower extremity inflammatory lymphedema (BLEIL) is a recently described condition that presents with exquisite tenderness, erythema, and edema of the lower leg, ankle and dorsal foot resembling an acute cellulitis. It was first reported in healthy, young adult military basic trainees with a normal body mass index during the first 72 hours of arrival to basic training. It occurs while standing at attention for many hours, and shows rapid resolution with elevation and rest. We report an additional case of BLEIL and describe the histopathology of this case and two of the previously reported cases...

Kikuchi-Fujmoto disease (KFD), also known as "histiocytic necrotizing lymphadenitis", is a rare lymphadenitis of unknown origin, but with an excellent prognosis. It is more common in Asia, but isolated cases are also reported in America, Africa and Europe. The disease can have an acute or subacute course, usually develops in 1 to 3 weeks, with spontaneous resolution in 1-4 months. The main clinical sign is cervical lymphadenopathy, especially in the posterior cervical triangle with bulky and painful lymph nodes, usually affecting only one side; rare cases of generalized lymphadenopathy can be seen...

Building permanent accommodation after a disaster takes time for reasons including the removal of debris, the lack of available land, and the procurement of resources. In the period in-between, affected communities find shelter in different ways. Temporary houses or transitional shelters are used when families cannot return to their pre-disaster homes and no other alternative can be provided. In practice, families stay in a standard interim solution for months or even years while trying to return to their routines...

All cell migration and wound healing assays are based on the inherent ability of adherent cells to move into adjacent cell-free areas, thus providing information on cell culture viability, cellular mechanisms and multicellular movements. Despite their widespread use for toxicological screening, biomedical research and pharmaceutical studies, to date no satisfactory technological solutions are available for the automated, miniaturized and integrated induction of defined wound areas. To bridge this technological gap, we have developed a lab-on-a-chip capable of mechanically inducing circular cell-free areas within confluent cell layers...

Twister RNAs represent a recently-discovered class of natural ribozymes that promote rapid cleaving of RNA backbones. Although an abundance of theoretical, biochemical, and structural data exists for several members of the twister class, disagreements about the architecture and mechanism of its active site have emerged. Historically, such storms regarding mechanistic details typically occur soon after each new self-cleaving ribozyme class is reported, but paths forward exist to quickly reach calmer conditions...

An acutely painful, erythematous wrist can be due to a variety of pathologic processes, including crystalline arthropathy, infection, trauma, osteoarthritis, and systemic disease. The broad differential diagnosis of the inflamed wrist and nonspecific clinical findings make accurate diagnosis challenging. There is no published clinical or laboratory criterion that reliably differentiates septic wrist arthritis from a sterile inflammatory arthropathy. For septic joint patients, long-term results are notably poorer in patients with a delay in treatment, therefore establishing evidenced-based guidelines deserves attention...
