Effects of External Ankle Support on Dynamic Movements: A Randomized Controlled Trial

Ankle sprains, are one of the most common injuries among athletes and individuals that perform dynamic activities on a daily basis. A common treatment or prevention for ankle sprain is the use of external ankle support in the form of braces or tape. This study\u27s purpose was to determine whether external ankle support influenced dynamic performance measures. The study consisted of 15 males and 15 females totaling thirty participants with a mean age of24.67 years old. Subjects were included if they were healthy and had no previous ankle injuries. Using the NeuroCom Balance Master 8.2, each subject performed two dynamic tests consisting of the Step Up and Over (SUO) and the Forward Lunge (FL) test. Each test was performed with the subject wearing ankle tape, an ankle brace, and no external support in addition to an athletic shoe on the right lower extremity. Forward lunge results revealed that lunge distances were highest with ankle tape but significant differences were seen only between the taping group and the bracing group. Movement time in the SUO test was shortest in the control group with significance achieved between the control group and the taping group. A significant difference was also demonstrated in this maneuver in impact index. No other significant differences were found between groups. In conclusion, these results indicate that the use of external ankle support for protection influences dynamic performance activities, some negatively, others positively, and extension may ultimately have an effect on more intense activities, such as cutting, jumping, changing direction, and other dynamic functional movements. In addition, the use of external support may also subject the ankle, knee, or hip to abnormal forms of stress when impacting the surface during these activities, which in turn may predispose these joints to injury or other problems

Praying Grounds: African American Faith Communities

More than a century after the publication of The Souls of Black Folk...the church remains at the center of African American social life. However, like other aspects of social history, much of the history of religious institutions is “disappearing beneath our feet,” because not enough is being done to collect and preserve the primary evidence of the work of the church and to make this archival information available to established and budding 21st-century scholars. Praying Grounds: African American Faith Communities promises to help address this problem through the collection and preservation of archival material related to the history of these institutions in Greater Cleveland... — Dr. Regennia N.

To Really Know the Disease: Creating a Participatory Community Education Workshop about Taenia solium Focused on Physical, Economic, and Epidemiologic Evidence

Cysticercosis, caused by Taenia solium, is a neglected disease that causes preventable epilepsy. We conducted an experiential learning workshop in northern Peru to educate community members on T. solium transmission and motivate participation in community-led prevention and control. The workshop included presentation of local economic and epidemiologic data, followed by hands-on participation in pig dissection, group discussion of the T. solium life cycle, and viewing of eggs and nascent tapeworms with light microscopes. Among heads of household, we used community survey data to compare knowledge of the three-stage parasite life cycle at baseline and 2 months postworkshop. Knowledge of the life cycle increased significantly after the workshop, with greater gains for workshop attendees than non-attendees. Prior knowledge and workshop attendance were significant predictors of postworkshop knowledge. The use of local evidence and experiential learning positively affected knowledge of T. solium transmission, laying the foundation for subsequent community-engaged control efforts

Size-dependent vibronic coupling in α-Fe2O3

We report the discovery of finite length scale effects on vibronic coupling in nanoscale α-Fe2O3 as measured by the behavior of vibronically activated d-d on-site excitations of Fe3+ as a function of size and shape. An oscillator strength analysis reveals that the frequency of the coupled symmetry-breaking phonon changes with size, a crossover that we analyze in terms of increasing three-dimensional character to the displacement pattern. These findings demonstrate the flexibility of mixing processes in confined systems and suggest a strategy for both enhancing and controlling charge-lattice interactions in other materials

Spin−Lattice Coupling in [Ni(HF2)(pyrazine)2]SbF6 Involving the HF2 − Superexchange Pathway

Magnetoelastic coupling in the quantum magnet [Ni(HF2)- (pyrazine)2]SbF6 has been investigated via vibrational spectroscopy using temperature, magnetic field, and pressure as tuning parameters. While pyrazine is known to be a malleable magnetic superexchange ligand, we find that HF2 − is surprisingly sensitive to external stimuli and is actively involved in both the magnetic quantum phase transition and the series of pressureinduced structural distortions. The amplified spin−lattice interactions involving the bifluoride ligand can be understood in terms of the relative importance of the intra- and interplanar magnetic energy scales

Evaluating Urban Taeniasis as a Threat to Cysticercosis Elimination in Northern Peru

Reintroduction of Taenia solium into a region in Peru where it had been eliminated prompted evaluation of the possibility of reintroduction from an urban reservoir of taeniasis. In a cross-sectional study of an adjacent urban area, we found low prevalence of taeniasis (4/1,621; 0.25%), suggesting minimal risk of parasite reintroduction into rural areas through this route

Magnetochromic sensing and size-dependent collective excitations in iron oxide nanoparticles

We combine optical and magneto-optical spectroscopies with complementary vibrational and magnetic property measurements to reveal finite length scale effects in nanoscale α-Fe2O3. Analysis of the d-to-d on-site excitations uncovers enhanced color contrast at particle sizes below approximately 75 nm due to size-induced changes in spin-charge coupling that are suppressed again below the superparamagnetic limit. These findings provide a general strategy for amplifying magnetochromism in α-Fe2O3 and other iron-containing nanomaterials that may be useful for advanced sensing applications.We also unravel the size dependence of collective excitations in this iconic antiferromagnet
