This pilot study is the first known in-depth case study of the effectiveness of virtual reality therapy (VRT) as a treatment for Test Anxiety (TA). The subject of the study was a 28-year-old male, whose anxiety and avoidance behavior was interfering with his normal academic activities. For treatment, he was placed in a virtual classroom and later in a virtual auditorium. The subject was exposed to six moderately increasing in difficulty level virtual situations. The subject rated each situation for discomfort. As a simple measure of anxiety, a modified version of the Subjective Units of Disturbance (SUD) scale was used every five minutes during exposure. This case study showed VRT to be an effective treatment method for reducing self-reported TA. Symptoms experienced by the subject during VRT sessions were just as real to the subject as actual test taking and general TA situations. They included increased heart rate, mild dizziness, and headaches. This case study of TA indicates that VRT may be used as an effective treatment method for reducing self-reported anxiety and improving the performance of subject(s) who suffer from TA.

Background: Different countries have varying dental specialities, shaped by diverse factors. The determinants influencing the development of these specialities differ between developed and developing countries. This study aimed to explore the factors contributing to the establishment of dental specialities in Iran, a developing country with a wide range of recognised dental specialities.

A 50-year-old woman with a 20-year history of gait instability presented with new-onset vertigo and oscillopsia. Examination revealed bilateral vestibular loss, cerebellar ataxia, sensory neuropathy, a "yes-yes" head tremor, nystagmus and a family history of a similar syndrome. Genetic testing for cerebellar ataxia with neuropathy and bilateral vestibular areflexia syndrome (RFC1) was negative, but whole exome sequencing identified a novel mutation in the DNA methyltransferase 1 (DNMT1) gene, broadening the differential diagnosis for this phenotype.

For commercial viability, cultivated meats require scientifically informed approaches to identify and manage hazards and risks. Here we discuss food safety in the rapidly developing field of cultivated meat as it shifts from lab-based to commercial scales. We focus on what science-informed risk mitigation processes can be implemented from neighbouring fields.

The establishment of site-specific target limits (SSTLs) for old municipal solid waste (MSW) dumpsites is essential for defining remediation goals in a scientifically rigorous manner. However, a standardized framework for achieving this is currently lacking. This study proposes a comprehensive framework that integrates high-resolution site characterization (HRSC) tools, targeted sampling, and contaminant transport modeling to derive SSTLs.
