Dancing on roller skates at discothecques has become very popular among the youth in the last number of years. During 1980 a number of these roller discotheques were opened in Belfast and it soon became apparent that significant numbers of young people were attending the Accident and Emergency Departments of hospitals in the city with injuries received while participating in this leisure activity.

Problem: The demand of beverages in PET bottles is constantly increasing. In this context, environmental, technological and regulatory aspects set a stronger focus on recycling. Generally, the reuse of recycled material from post-consumer PET bottles in bottle-to-bottle applications is seen as least environmentally harmful. However, closedloop systems are not widely implemented in Europe. Previ...

AIM This study aims to determine the effect of the stationary rawx, roller, and the suspension cell culture systems on the total virus yield infectivity and antigenicity. MATERIALS AND METHODS Three serotypes of foot and mouth disease virus (FMDV) (serotype A, O and SAT-2) were inoculated separately into baby hamster kidney-21 cell line in rawx, roller, and suspension cultivation systems usin...

Interactions between tethered layers composed of aggrecan (charged bottle-brush) macromolecules are responsible for the molecular origin of cartilage biomechanical behavior. To elucidate the role of the electrostatic forces in interaction between bottle-brush layers, we have performed molecular dynamics simulations of charged and neutral bottle-brush macromolecules tethered to substrates. In th...

This study was undertaken to modify and develop procedures for tissue culture-inactivated Japanese B encephalitis (JBE) virus vaccine production in large quantities. Various types of glass bottles were tried and, considering many advantages, long cylindrical roller (CR) bottles were selected. Several variables were investigated including number and volume of trypsinized cells to be seeded, volu...

Conventional high-dose chemotherapy frequently leads to severe neutropenia, during which patients experience a high risk of infection. Although support care with donor's neutrophils is possible this choice is largely hampered by the limited availability of matched donors. To overcome this problem, we explored a large-scale ex vivo production of neutrophils from hematopoietic stem cells (HSCs) u...

Using the BacT/Alert automated system, we conducted a 1-year retrospective study on blood cultures, focusing on the relevance of routine use of the anaerobic bottle. The rate of patients with positive blood cultures was 19.7%. Among these, 13.5% had a positive anaerobic bottle in the absence of any aerobic bottle, and 2/3 of these grew with nonobligate anaerobes. These patients were hospitalize...

Blood was cultured in two vacuum bottles containing Columbia broth. Filtered air was admitted to one bottle (aerobic); the unvented bottle was considered anaerobic. Cultures were incubated at 35 C until growth occurred or for at least 7 days. Of 744 organisms isolated, 50% were isolated from both bottles, 30% from the aerobic bottle only, and 20% from the anaerobic bottle only. These results in...

With the European Green Deal, importance of recycled products and materials has increased. Specifically, for PET bottles, a high content material (rPET) is demanded by industry consumers. This study was carried out in lab environment replicating real-life industrial processes, to investigate possible impacts on rPET quality over eleven recycling loops, aiming use amounts repetitively. A cycle i...
