We evaluated the Relaxation Zone (RZ), a room with "relaxation stations" designed to reduce stress in college students. Participants ( = 994) were enrolled during the 2019 calendar year. Most participants were female (62.8%), freshmen (59.3%), and African American (44.9%). Students visiting the RZ completed a brief pretest and posttest that measured self-reported stress. Paired sample -tests across class groups (e.g., freshman, sophomore) revealed a significant reduction in stress from pretest ( = 6.0) to posttest ( = 4.5), with medium to large effect sizes (Cohen's ranging from 0.53 to 0.88) during their first visit. For students having at least two visits ( = 348), an exploratory dose-response analysis demonstrated that an optimal dose of self-guided relaxation ranged from two to eight visits. These findings provide initial evidence that programs like the RZ can reduce student stress within a few visits.

Background: The detection of prostate cancer (PCa) via conventional magnetic resonance imaging (MRI) in patients with prostate-specific antigen (PSA) levels within the grey zone remains challenging. Whether synthetic MRI can provide supplementary benefits for the accurate diagnosis of PCa in this specific population is still unknown. This study aims to investigate the diagnostic performance of synthetic MRI for differentiating PCa lesions from noncancerous lesions in patients with PSA levels within the grey zone (4-10 ng/mL).

In the present manuscript, we highlight the contradictions in the thermally activated processes theory which treats a system's activated state as a state of the phonon subsystem. We offer an alternative model, in which the activated state is treated as an electron subsystem state. The mechanism of the activated state formation is as follows: thermal fluctuations excite electrons of some particles within the activation zone.

Ptychography has evolved as an important method for nanoscale X-ray imaging with synchrotron radiation. Recently, it has been proposed to work with multiple beams in parallel. The main advantage of so-called multi-beam ptychography is that larger areas can be imaged much faster than with a conventional single beam scan.

Background: Internationally adopted Chicago Classification (CC) criteria based on adult normative data have been used to diagnose children with esophageal motility disorders undergoing high-resolution esophageal manometry (HREM). The aim of this study was to compare HREM parameters of children without dysphagia and children with dysphagia and normal findings according to CC.
Methods: HREM metrics of 41 children (13.
