BACKGROUND Little solid information is available on the possible risks for neuronal injury in amateur boxing. OBJECTIVE To determine whether amateur boxing and severity of hits are associated with elevated levels of biochemical markers for neuronal injury in cerebrospinal fluid. DESIGN Longitudinal study. SETTING Referral center specializing in evaluation of neurodegenerative disorders. ...

The distribution of radiocesium was examined in bamboo shoots, Phyllostachys pubescens, collected from 10 sites located some 41 to 1140 km from the Fukushima Daiichi nuclear power plant, Japan, in the Spring of 2012, 1 year after the Fukushima nuclear accident. Maximum activity concentrations for radiocesium ¹³⁴Cs and ¹³⁷Cs in the edible bamboo shoot parts, 41 km away from the Fukushima Daiichi...

he possibility to obtain sintered material from alkaline basaltic tuffs is demonstrated. The parent rock was milled for 10–15 min, the resulting owder was pressed at 100 MPa and the obtained samples were heat-treated in the range of 1000–1140 ◦C. The sintering behaviour and the phase ormation were studied by pycnometry, dilatometry, DTA, XRD and SEM. The final material was obtained by sintering...

was obtained from Bacteroides symbiosus cell extracts and was purified from interfering enzyme activities. It was strongly stimulated by ammonium ion. In this respect and in other physical properties the bacterial enzyme differed from that previously obtained from Entamoeba histolytica. In a complete reaction system the enzyme transferred label from orthophosphate to pyrophosphate and to the y ...

Kaposi's sarcoma-associated herpesvirus (KSHV) stabilizes hypoxia-inducible factor α (HIF-1α) during latent infection, and HIF-1α reactivates lytic replication under hypoxic stress. However, the mechanism utilized by KSHV to block lytic reactivation with the accumulation of HIF-1α in latency remains unclear. Here, we report that LANA encoded by KSHV contains a unique SUMO-interacting motif (LAN...

Contour clamped homogeneous field (CHEF) agarose gel electrophoresis (AGE), ramped to give linear separation of DNA molecules of 600-1600 kilobase pairs (kbp), was used to determine mobilities for full-sized genomic DNA of the serotype standard strains of the human genital mollicutes, Ureaplasma urealyticum relative to yeast chromosomal DNA markers. Indicated genome sizes (in kbp) were 760 for ...

The Thomson scattering diagnostic on MST records both equilibrium and fluctuating electron temperature with a range capability of 10 eV-5 keV. Standard operation with two modified commercial Nd:YAG lasers allows measurements at rates of 1 kHz-25 kHz. Several subsystems of the diagnostic are being improved. The power supplies for the avalanche photodiode detectors (APDs) that record the scattere...

The decline in ocean water pH and changes in carbonate saturation states through anthropogenically mediated increases in atmospheric CO2 levels may pose a hazard to marine organisms. This may be particularly acute for those species reliant on calcareous structures like shells and exoskeletons. This is of particular concern in the case of valuable commercially exploited species such as the king ...

Methods and results We have studied the Cochrane systematic reviews addressing the systemic use of corticosteroids in: • acute bacterial meningitis (to examine the effect versus placebo on mortality, hearing loss and neurological sequelae in participants of all ages); 24 randomized controlled trials (RCTs) enrolling 4041 patients; • tuberculous meningitis (to examine the effect on death or disa...
