Understanding Baseline Concussion Testing: A Resource for School Nurses as Members of Concussion Management Teams.

Sports-related concussions (SRCs) are not uncommon among teen athletes. School nurses are in an ideal position to care for athletes affected with SRCs. However, evidence suggests there is a lack of knowledge regarding concussion management, use of baseline concussion testing, and active involvement on concussion management teams among school nurses.

Gravity-Based Methods for Heading Computation in Pedestrian Dead Reckoning.

One of the common ways for solving indoor navigation is known as Pedestrian Dead Reckoning (PDR), which employs inertial and magnetic sensors typically embedded in a smartphone carried by a user. Estimation of the pedestrian's heading is a crucial step in PDR algorithms, since it is a dominant factor in the positioning accuracy. In this paper, rather than assuming the device to be fixed in a certain orientation on the pedestrian, we focus on estimating the vertical direction in the sensor frame of an unconstrained smartphone.

Balancing the intermolecular forces in peptide amphiphiles for controlling self-assembly transitions.

While the influence of alkyl chain length and headgroup size on self-assembly behaviour has been well-established for simple surfactants, the rational control over the pH- and concentration-dependent self-assembly behaviour in stimuli responsive peptides remains an elusive goal. Here, we show that different amphiphilic peptides can have similar self-assembly phase diagrams, providing the relative strengths of the attractive and repulsive forces are balanced. Using palmitoyl-YYAAEEEEK(DO3A:Gd)-NH and palmitoyl-YAAEEEEK(DO3A:Gd)-NH as controls, we show that reducing hydrophobic attractive forces through fewer methylene groups in the alkyl chain will lead to a similar self-assembly phase diagram as increasing the electrostatic repulsive forces via the addition of a glutamic acid residue.

[Nonviral sexually transmitted infections-epidemiology, clinical manifestations, diagnostic workup, therapy : Part 3: Treponemes, Gardnerella and trichomonads].

In Germany, the reported syphilis prevalence has increased continuously since 2010, with a total of 6834 syphilis cases being reported in 2015. The largest increase of reported syphilis occurred in men who have sex with men (MSM). The antibiotic agent of choice for treatment of syphilis is still penicillin.

[Non-viral sexually transmitted infections - Epidemiology, clinical manifestations, diagnostics and therapy : Part 2: Chlamydia and mycoplasma].

Chlamydia trachomatis is the most common pathogen of sexually transmitted bacterial infections worldwide. Every year in Germany approximately 300,000 new infections are to be expected. Chlamydia infections occur nearly exclusively in the postpubertal period.
