the c3 phenotypes were determined by high-voltage agarose gel electrophoreses in german patients suffering from lymphosarcoma (n=34), hodgkin (n=59) and a group of other haematological diseases (n=46). frequencies of c3 ss, sf and ff pho=enotypes were not significantly different from the frequencies found in a control group of 322 healthy germans. however, high frequency of the ff phenotype in ...

AMPK amplifies Huntington’s disease J u et al. describe how hyperactivation of AMPactivated protein kinase (AMPK) promotes neurodegeneration in Huntington’s disease (HD). The aggregation of mutant Huntingtin protein in HD disrupts many cellular processes, including metabolism. AMPK—a protein that maintains energy homeostasis—is abnormally active in the brains of mice with HD, but whether the ki...

We studied the influence of spatial visual attention on the time-course of primed pointing movements. We measured pointing responses to color targets preceded by color stimuli priming either the same or opposite response as the targets. Effects of visual attention at the prime/target locations were studied by giving endogenous attentional cues whose processing was a precondition for performing ...

COVID-19 has had asymmetrical spatial impacts across South Africa. New evidence from the National Income Dynamics Study: Coronavirus Rapid Mobile (NIDS-CRAM) survey shows that pandemic and lockdown reflex have magnified pre-existing divisions within cities. Although severely impacted whole country, townships informal settlements proved more vulnerable than suburbs. As Africa was already one of ...

This research evaluates the effectiveness of using a roller-type base isolation device with tensile strength in reducing dynamic response industrial steel storage racks. These were subjected to seismic input acting separately both directions structure. The record obtained from earthquake that occurred Llolleo, Chile, on 3 March 1985, was used as input. scaled frequency domain, adjusting its spe...
