BACKGROUND Non-steroidal anti-inflammatory drugs (NSAIDs) are a frequent cause of hypersensitivity reactions, therefore, in clinical practice, it's important to find safe and effective substances. OBJECTIVE To evaluate the tolerability of etoricoxib and its subsequent actual use and safety at home. METHODS Etoricoxib tolerance was assessed by single-blind-placebo-controlled oral challenges ...

Dear Editor-in-Chief Nuclear energy is economically feasible. Therefore, nuclear power plants produce about 16% of the world’s electricity nowadays. Calder Hall in the United Kingdom is the world’s first commercial nuclear power station in 1956 (1). In the United States, Shippingport was first operated since 1957. However, the accident like Three Mile Island and Chernobyl disaster had awakened ...

The requirements for OLTP database systems are becoming ever more demanding. New OLTP applications require high degrees of scalability with controlled transaction latencies in in-memory databases. Deployments of these applications require low-level control of database system overhead and program-to-data affinity to maximize resource utilization in modern machines. Unfortunately, current solutio...

The primary treatment of municipal wastewater was investigated in three high-rate anaerobic filter (AF) reactors operated in parallel at different hydraulic retention time (HRT) of 0.5, 1 and 1.5 h at low ambient temperature (average = 13°C). The media in each reactor consisted of vertical sheets of reticulated-polyurethane foam (RPF) with knobs. The results demonstrated that the AF reactor was...

BACKGROUND The relationship between hypersensitivity to NSAID and atopic status is still incompletely defined. Previous studies found a high prevalence of atopic diseases in multiple NSAID reactors. The present study aimed to investigate whether this is the case also in Italian adults hypersensitive to NSAIDs. METHODS Skin tests with a large panel of seasonal and perennial airborne allergens ...

Polymer synthesis. A Chemspeed Swing-SLT automated synthesizer was used for the parallel synthesis.16 The reactions were performed in a glass reactor block of 16 reactors (13 mL) with thermal jackets. These were connected in series to a Hüber thermoregulation system (−90 °C to 140 °C). The reactors were equipped with cold-finger reflux condensers and mixing was done by vortex agitation. The liq...

background: biological shielding of nuclear reactors has always been a great concern and decreasing the complexity and expense of these installations is of great interest. in this study, we used datolite and galena (daga) minerals for production of a high performance heavy concrete. materials and methods: datolite and galena minerals which can be found in many parts of iran were used in the con...
