RezRIDERS: A Tribally-Driven, Extreme Sport Intervention & Outcomes.

Reducing Risk through Interpersonal Development, Empowerment, Resiliency, and Self-Determination (RezRIDERS) is a tribally-driven youth empowerment program designed to deter substance abuse and depression symptomology among high-risk American Indian youth while increasing hope/optimism, self-efficacy, and pro-social bonding. The quasi-experimental intervention took place between 2012-2015 in the Pueblo of Jemez (New Mexico, USA). The community-based program served fifty-five total youth.

Relationship of pressure pain thresholds between the masticatory muscles and styloid process. Part 2. Healthy subjects and patients with temporomandibular disorders.

Purpose: We previously reported correlations between the pressure pain threshold (PPT) at the styloid process, which represents individual pain sensitivity, and PPTs of the masticatory muscles in healthy subjects, and proposed the 95% confidence interval (95%CI) of the PPT at the styloid process as a reference range. In this study, we evaluated its usefulness as a reference range.

Methods: Serial changes in the PPT relative to the 95%CI were studied in 7 healthy subjects.

Visualization and quantitative analysis using normalized electromyographic linear envelopes of muscle contraction patterns during gum chewing.

Surface electromyography (EMG) has been widely used in clinical dentistry, although interpretation of the raw data is difficult owing to its low reproducibility. Linear EMG envelopes, also known as EMG profiles, which are normalized with respect to raw EMG amplitudes and stride, have been developed to analyze the time course of gait stride. Normalized EMG contraction patterns can be used for comparing individuals or recording sessions on the same individual made at different times.

Differentiation of malignant glioma and metastatic brain tumor by thallium-201 single photon emission computed tomography.

The use of superdelayed thallium-201 single photon emission computed tomography (201Tl SPECT) for differentiating malignant gliomas from cerebral metastases was investigated in 23 patients (7 with meningioma, 6 with glioma, 7 with cerebral metastasis, 1 with each of neurinoma, abscess, and necrosis). 4 mCi of 201Tl was injected intravenously, and gamma camera scans were performed after 10 minutes and 4, 24, 72, and 96 hours (superdelayed scan). The mean thallium index of meningiomas was significantly higher than those of gliomas and cerebral metastases after 10 minutes, while the mean thallium indices of meningiomas and gliomas were significantly higher than those of cerebral metastases after 96 hours.
