Younger adults (YA) and older adults (OA) used a joystick to stabilize an unstable visual inverted pendulum (VIP) with a fundamental frequency (.27 Hz) of half that of bipedal human sway. Their task was to keep the VIP upright and to avoid ± 60° "fall" boundaries.

While gas chromatography mass spectrometry (GC-MS) has long been used to identify compounds in complex mixtures, this process is often subjective and time-consuming and leaves a large fraction of seemingly good-quality spectra unidentified. In this work, we describe a set of new mass spectral library-based methods to assist compound identification in complex mixtures. These methods employ mass spectral uniqueness and compound ubiquity of library entries alongside noise reduction and automated comparison of retention indices to library compounds.

Two-sample capture-recapture studies are commonly used in the epidemiological and ecological literature. Most of these studies have been limited to analysis using the Lincoln-Petersen estimator, especially in epidemiological studies. We examine the use of the Lincoln-Petersen estimator and two alternative closed-population methods: Huggins' conditional likelihood method and Pledger's likelihood method with mixtures.

Background: Friedreich ataxia is a rare neurodegenerative disorder caused by frataxin deficiency. Both underweight and overweight occur in mitochondrial disorders, each with adverse health outcomes. We investigated the longitudinal evolution of anthropometric abnormalities in Friedreich ataxia and the hypothesis that both weight loss and weight gain are associated with faster disease progression.

Abnormal tryptophan metabolism is closely linked with neurological disorders. Research has shown that indoleamine 2,3-dioxygenase 1 (IDO-1), the first rate-limiting enzyme in tryptophan degradation, is upregulated in Parkinson's disease (PD). However, the precise role of IDO-1 in PD pathogenesis remains elusive.
