Observations of the ozone profile by a groundbased microwave radiometer in Switzerland indicate a dominant 20-day oscillation in stratospheric ozone, possibly related to oscillations of the polar vortex edge during winter. For further understanding of the nature of the 20-day oscillation, the ozone data set of ERA Interim meteorological reanalysis is analyzed at the latitude belt of 47.5 N and ...

Doppler measurements from the Keck/HIRES spectrometer of the G3 V star HD 187123 reveal Keplerian variations with a period of 3.097 days and a semiamplitude of 72 m s. An orbital fit yields a companion mass of , a semimajor axis of AU, and an eccentricity of M 5 0.52 M / sin i a 5 0.042 e 5 0.03 JUP (consistent with zero). HD 187123 appears similar to the Sun in mass, age, chromosphere, and rot...

Functional overreaching has been linked to alterations in immunity and host pathogen defense, but little is known as to whether or not running and cycling evoke different responses. This study compared inflammation, muscle damage and soreness, and innate immune function responses to a 3-day period of intensified exercise in trained long distance runners (N=13, age 34.4±2.4year) and cyclists (N=...

BACKGROUND This investigation compared the effects of an extended period of weight-bearing (running) vs. non-weight-bearing (cycling) exercise on hepcidin production and its implications for iron status. METHODS Ten active males performed two separate exercise training blocks with either running (RTB) or cycling (CTB) as the exercise mode. Each block consisted of five training sessions (Day 1...

In Europe, Germany is taking the lead in the switch from the conventional to renewable energy. This poses new challenges as wind and solar energy are fundamentally intermittent, weather-dependent and less predictable. It is therefore of considerable interest to investigate the evolution of price volatility in this post-transition era. There are a number of reasons, however, that makes the pract...

In the 1960s, Winter (1962) identified that moisture was required to provide an optimum environment for reepithelialisation (and hence healing) to occur. Since then, further research has added to our knowledge and now the broad criteria for an ideal wound dressing includes: Provision of a moist environment Protection from the external environment (including the prevention of ingress of foreign ...

For the optimal recovery of Mycobacterium tuberculosis from the BACTEC™ Mycobacterium Growth Indicator Tube 960™ system, an incubation period of 42-56 days is recommended by the manufacturer. Due to logistical reasons, it is common practice to follow an incubation period of 42 days. We undertook a retrospective study to document positive Mycobacterium Growth Indicator Tube cultures beyond the 4...

Borrelia burgdorferi infection in beagle dogs was studied quantitatively with skin punch biopsy samples and blood samples collected at 4- and 2-week intervals, respectively, over a 500-day period. Thereafter, 25 tissue samples of each dog were collected for further analysis. Starting at day 120 after tick challenge, 12 dogs were treated with antibiotics (azithromycin, ceftriaxone, or doxycyclin...

Tuberculosis (TB) is one of the oldest, the most expanded and the most lethal diseases in human history. Although Koch's discovery of the TB causative agent (1882) represented a great progress in the fight against this infectious disease, it took a significant amount of time to reduce morbidity and mortality in the world. In Bosnia and Herzegovina (B&H) it was necessary to implement actions in ...

Blood culture records from 1994 to 1995 from five U.S. medical centers all using the Difco ESP continuous monitoring blood culture system were reviewed retrospectively. Among a total of 7,362 isolates of bacteria and yeasts, only 0.1% of possibly significant isolates would have been missed had blood cultures been routinely incubated for 4 days instead of the 5 days recommended by the manufactur...
