Effect of different intervals of verbal motivation during dispatcher-assisted CPR: A randomized controlled simulation trial.

Aim Of The Study: High quality chest compressions are essential for survival and good neurological outcome in out-of-hospital cardiac arrest (OHCA). Dispatcher- assisted CPR (DA-CPR) has led to increased survival in OHCA. Recently, additional verbal motivation has shown positive effects on CPR quality.

[Sonography of muscles : Rheumatology-Neurology-Geriatrics-Sports medicine-Orthopedics].

Muscle sonography is used in rheumatology, neurology, geriatrics, sports medicine and orthopedics. Muscular atrophy with fatty and connective tissue degeneration can be visualized and must be interpreted in conjunction with the sonographic findings of the supplying nerves. Sonography is becoming increasingly more important for the early diagnosis of sarcopenia in rheumatology, geriatrics and osteology.

Single-Molecule Catalysis in the Palladium Cross-Coupling Reaction Cycle.

Single-molecule (SM) methods are applied to study various types of catalytic processes in chemical and biochemical reactions. In this study, the Suzuki-Miyaura cross-coupling reaction forming a fluorescent product is investigated within the SM approximation. Stochastic analysis of emission intermittency in selected nanoscopic spots allows us to determine the single-molecule turnover frequency (SM-TOF) of the Pd catalyst in a specific probe reaction.

Acid selenites as new selenium precursor for CdSe quantum dot synthesis.

Chemical precursors for nanomaterials synthesis have become essential to tune particle size, composition, morphology, and unique properties. New inexpensive precursors investigation that precisely controls these characteristics is highly relevant. We studied new Se precursors, the acid selenites (R-O-SeOOH), to synthesize CdSe quantum dots (QDs).

[Ultrasound of nerves of the lower extremities].

The ability to visualize the nerves of the lower extremities differs from that of the upper extremities in sonography because the soft tissue cover is significantly larger in some cases. Landmarks are also defined for the lower extremities, which enable precise visualization of the nerves. Nerves and muscles are to be understood as a functional unit.
