This study examined the impact of simulated hearing loss on reactive balance control in healthy young and older adults. Participants performed dual-task scenario involving auditory sentence repetition and unexpected surface translations. Hearing loss was simulated using Adobe Audition, applying frequency-specific attenuation based on moderate sensorineural hearing loss levels from the literature. Speech-in-noise performance significantly declined under simulated hearing loss for both age groups (p < .001), confirming effective simulation, but not significant differences were found between age groups. Maximum COP-COM displacement (the scalar distance between Center of Pressure and Center of Mass) increased with perturbation intensity (Level 1 vs. Level 2: p < .001), but no significant differences were found between hearing conditions or age groups (p > .05), suggesting compensatory step execution was preserved. Reaction time analysis revealed a significant interaction between hearing condition and perturbation level (p < .01). Older adults showed a smaller reduction in reaction time between Level 1 and Level 2 perturbations under simulated hearing loss (Level 1: 283±37 ms; Level 2: 224±20 ms) compared to normal hearing (Level 1: 298±42 ms; Level 2: 230±20 ms), indicating impaired ability to modulate initiation of reactive balance strategies during loss of balance with auditory challenge. These findings suggest that while older adults maintain compensatory stepping ability, simulated hearing loss may hinder their ability to adapt reaction timing during challenging dual-task scenarios. This impairment may contribute to increased fall risk in older adults with hearing loss. Further research is needed to explore underlying cognitive mechanisms and develop targeted interventions.","PeriodicalId":91036,"journal":{"name":"Pacific journal of health (Stockton, Calif.)","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13327732/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148378502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, many institutions in the United States have been slow to develop “progress” exams designed to assess to test individual student progress towards graduation. Literature review found scant evidence of schools reporting design and implementation of such assessments. This paper shares the process piloted at one U.S. dental school to develop a case-based written exam, map test items to concepts/knowledge expected of students and evaluate the validity and effectiveness of the exam as a useful measure of learning progress. It also analyzes the correlation between other existing student performance measures and scores on this assessment. Regression analysis revealed that student performance measures such as undergraduate grade point average (GPA), academic standing in the program, class rank, and first-time success or failure on the National Board Dental Exam (NBDE) Part II all had significant positive correlation with student scores on this assessment examination. This assessment was found to have a strong reliability score as well. Although piloted in a dental school, the methodology employed in this exam creation may provide a pedagogical model for building comprehensive assessments in other professional or vocational training programs providing valuable early identification of students not progressing towards competency in time for remedial action to be taken.","PeriodicalId":91036,"journal":{"name":"Pacific journal of health (Stockton, Calif.)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41443447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its success, there are some common, stubborn problems encountered by research scientists when they try to use the yeast to produce their recombinant proteins. In order to provide those working in this field with strategies to overcome these common obstacles, nine experts in P. pastoris protein expression field were interviewed to create a written review and video (https://www.youtube.com/watch?v=Q1oD6k8CdG8). This review describes how each respected scientist addressed a specific challenge, such as identifying high expression strains, improving secretion efficiency and decreasing hyperglycosylation. Their perspective and practical advice can be a tool to help empower others to express challenging proteins in this popular recombinant host.","PeriodicalId":91036,"journal":{"name":"Pacific journal of health (Stockton, Calif.)","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9536841/pdf/nihms-1837807.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33498324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
