The effectiveness of different attentional foci on the acquisition of sport-specific motor skills in healthy adults: a systematic review with network meta-analysis.

Background: The acquisition of motor skills is a key element in many sports. A motor learning principle, which is frequently used to support skill acquisition is the application of different attentional foci. The effectiveness of different attentional foci on performance and the learning of motor skills has been investigated in various sports using randomised controlled trials.

In the eye of the hurricane: the Swiss COVID-19 pandemic stepwise shutdown approach in organ donation and transplantation.

The Swiss stepwise shutdown approach in organ donation and transplantation helped to maintain a limited national organ procurement and vital organ transplant activity, avoiding a complete nationwide shutdown of organ donation and transplant activity. .

Expression of Semliki Forest virus E1 protein in Escherichia coli. Low pH-induced pore formation.

Exposure of Semliki Forest virus 1 to mildly acidic conditions results in conformational changes of the viral spike proteins, which in turn leads to a pore formation across its membrane. The ability to form a pore has been ascribed to the ectodomain of the Semliki Forest virus (SFV) E1 spike protein. To elucidate whether the E1 protein per se is sufficient for low pH-dependent pore formation, we expressed E1 in Escherichia coli in an inducible manner using the pET11c expression system.
