It was hypothesized that texting would decrease stride velocity and increase deviation from midline while walking, as well asincrease centre of pressure (CoP) excursions while standing. Fifteen participants (eleven males and four females, 21.12±1.25 yearsof age) performed two standing balance tasks and two walking tasks. A repeated measures experimental design was used. Thestanding task consisted of standing as still as possible on a force plate for 20 seconds, which was then repeated while theparticipant texted a standard text message (48 characters). The second task consisted of walking along a six metre straight linewhile being filmed posteriorly along the line of progression, and perpendicular to direction of motion. This task was completed againwhile texting a similar predetermined message (48 characters). Balance performance was quantified by the percentage of total timewithin a 5 mm radius of each participant’s centre of pressure (CoP). Gait quality was quantified using the average step length, stridevelocity, and mediolateral standard deviation from midline averaged from both feet. The percentage of time spent within 5 mm of theaverage CoP was significantly (p<0.05) less while texting compared to the non-texting control condition. Additionally, themediolateral standard deviation from the midline while walking increased significantly (p<0.05) in the texting condition. Average steplength and average stride velocity decreased significantly (p<0.05) while texting compared to the control condition. Standing balanceand temporospatial aspects of walking are significantly degraded by texting. These results are valuable due to the growingprevalence of mobile technology. These results suggest that texting and walking could be detrimental to pedestrian safety and canhelp inform decisions regarding infrastructure to minimize potential dangers associated with distracted walkers.","PeriodicalId":321920,"journal":{"name":"Western Undergraduate Research Journal: Health and Natural Sciences","volume":"339 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116448259","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}

The molecular mechanisms behind the effects of individual phytochemicals in EOs and antibiotics is well understood, unlike the mechanisms behind the interactions between multiple phytochemicals and antibiotics in a mixture. Serratia liquefaciens and Sporosarcina ureae were exposed to various treatments of different combinations of Lavandula officinalis (lavender oil), Cymbopogon citratus (lemongrass oil) with ampicillin. For each treatment group, mean zones of inhibition (ZOI) were measured after exposure for 48 hours. Controls for both species did not yield any ZOI whereas all other treatments resulted in the inhibition of bacterial growth in both Serratia liquefaciens and Sporosarcina ureae. Statistical analyses showed that the combination of lemongrass oil and ampicillin was significantly more effective than all other treatments for Serratia liquefaciens. The lemongrass oil and ampicillin treatment was the only treatment that displayed additive effects. All treatments for Sporosarcina ureae, with the exception of the control and lavender oil treatments, showed a significantly higher mean ZOI when compared to control and lavender oil treatments. It was concluded that lemongrass oil was a better candidate to be included in antibacterial cocktails than lavender oil. However, further investigation is required to elucidate EOs that interact synergistically with ampicillin when acting on Serratia liquefaciens and Sporosarcina ureae. Additionally, further investigation into the molecular mechanisms behind the interactions of the components found in these EOs with ampicillin is required. \u0000","PeriodicalId":321920,"journal":{"name":"Western Undergraduate Research Journal: Health and Natural Sciences","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124223383","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}

More specifically, each type has its advantages, disadvantages, and ideal circumstances in which it should be used. This paper explores the systematic review, scoping review, and rapid review in the context of research that seeks to assess existing health care programs. Evidence suggests that the systematic review is the most rigorous and in-depth, but often takes a significant amount of time to complete. The scoping review is less rigorous and used to identify what is known about a specific topic in the literature. The rapid review is similar in rigour to the systematic review, but takes less time and is often used in situations where data needs to be obtained quickly. In this paper, strengths and weaknesses, alongside examples of each review are given. They are then analyzed to see which would be best to utilize for the topic of assessing existing health care programs. In closing, it is decided that the rapid review is the best method due to its limited time frame and extensive rigour, which is the most beneficial when assessing health care programs. \u0000","PeriodicalId":321920,"journal":{"name":"Western Undergraduate Research Journal: Health and Natural Sciences","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121399089","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}
