OBJECTIVE The relatively low success rate of the treatment maneuver for horizontal semicircular canal (HSC) benign paroxysmal positional vertigo (BPPV) may be caused by the difficulty determining the affected side. We developed a 180-degree supine roll test (SRT) by modifying the 90-degree SRT to increase diagnostic accuracy and evaluated its significance. STUDY DESIGN A prospective study. ...

The only curative therapeutic option for patients with BR is the so-called salvage radiotherapy (SRT). However, about 50% of the patients will experience a biochemical (as a reliable surrogate for tumor control) or a clinical recurrence after SRT within the following five years [3]. Retrospective analyses revealed PSA level before SRT and dose of SRT as the most significant risk factors for fai...

Wingless (Wg) is a secreted ligand that differentially activates gene expression in target tissues. It belongs to the Wnt family of secreted signaling molecules that regulate cell-to-cell interactions during development. Activation of Wg targets is dependent on the ligand concentration in the extracellular milieu; cellular mechanisms that govern the synthesis, delivery and receipt of Wg are ela...

Mechanical loading modulates the osteocyte-derived protein sclerostin, a potent inhibitor of bone formation. We hypothesized that simulated resistance training (SRT), combined with alendronate (ALEN) treatment, during hindlimb unloading (HU) would most effectively mitigate disuse-induced decrements in cortical bone geometry and formation rate (BFR). Sixty male, Sprague-Dawley rats (6-mo-old) we...

PURPOSE Salvage radiotherapy (SRT) is commonly used to treat patients with biochemical failure after radical prostatectomy (RP). Retrospective series have demonstrated biochemical response in approximately 60-75% of patients, but only a significantly lower rate of patients achieves a response with a decrease of the prostate-specific antigen (PSA) to a value below the limits of detectability. Th...

PURPOSE To evaluate the prognostic value of prostate-specific antigen (PSA) decline during salvage radiation therapy (SRT) after prostatectomy. METHODS AND MATERIALS We reviewed an institutional database and identified all prostate cancer patients who were treated with SRT between the years 2003 and 2010, had at least 1 PSA measurement during their SRT course, and had no history of androgen d...

In this study, the effect of sludge retention time (SRT) on oxic-settling-anoxic (OSA) process was determined using a sequencing batch reactor (SBR) attached to external aerobic/anoxic reactors. The SRT of the external reactors was varied from 10 to 40d. Increasing SRT from 10 to 20d enhanced volatile solids destruction in the external anoxic reactor as evidenced by the release of nutrients, ho...

Objectives Radiation-induced aneurysm is a rare complication for head and neck tumors. Only seven cases of an aneurysm after stereotactic radiosurgery and/or stereotactic radiotherapy (SRT) have been described. We report two patients with a ruptured internal carotid artery (ICA) aneurysm presenting with catastrophic epistaxis after repeated SRT for an anterior skull base tumor. Results Two male...

BACKGROUND AND PURPOSE The sit-and-reach test (SRT) is commonly used to assess flexibility of the spine and length of the hamstring muscles. The purposes of this study were (1) to describe hamstring muscle length as reflected by use of the SRT and the hip joint angle (HJA) in children, (2) to examine the correlation between SRT and HJA measurements, and (3) to examine gender differences for bot...
