Chemotaxis describes the biased directional movement of bacteria either towards or away from a substance. This phenomenon is created by the inhibition or potentiation of tumbling events, which randomize the direction of the host every few seconds. The presence of chemoattractants and chemorepellents can modify the number of tumbling events that occur. In order to elucidate the role of bacteriophages in bacterial chemotaxis, this project aimed to optimize an assay to qualitatively observe chemotaxis within E. coli BW2511 (WT) in comparison to a mutant strain with cheA deletion. Three main assay methods were tested: Tris HCl plate assays, Tris HCl microcapillary assays, and TTC Eppendorf assays. Of all the methods tested, only TTC Eppendorf assays with TTC indicator consistently showed chemotaxis. This study continued to use the Eppendorf assay and determined if various bacteriophages could attract E. coli BW2511 to chemotactically move up a layer of 0.4% PBS-based agar and against gravitational pull. \u0000 \u0000 \u0000 \u0000","PeriodicalId":22813,"journal":{"name":"The Meducator","volume":"120 4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76255110","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}

Of the many infections transmissible through tick bites, Lyme disease is the most well-known. However, lesser known tick-borne diseases, such as Powassan encephalitis, can have debilitating, or even lethal complications. The incidence of all tick-borne infections has increased over the past decade, with reported cases of Lyme disease seeing a tenfold increase. Identifying both Lyme disease and Powassan encephalitis can be challenging, as patients only show abnormalities in the later stages of disease progression. Even following successful treatment for Lyme disease, patients may continue to suffer from chronic disease sequelae. As tick populations continue to increase, primary prevention is the most effective method of combating tick-borne diseases.","PeriodicalId":22813,"journal":{"name":"The Meducator","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90261448","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 purpose of this review is to take a broad look at the researchon the hidden curriculum in an attempt to better understand its current value andfuture potential, as it affects nursing students and the profession. A brief historyof the hidden curriculum is provided in relation to nursing education, followed bya review of the literature with a specific focus on the variety of educational andclinical applications in which it plays important roles. These topics arose frominteractions with peers, nurses, non-faculty staff, and other community members,all of which had potential impacts on the students. Ultimately, the hidden curriculumis an understudied, underappreciated component of education, and is one in whichstudents play a major personal role in developing. Both faculty and students need tounderstand the power and importance of this tool, as it has the capacity to shapethe future of the nursing profession.","PeriodicalId":22813,"journal":{"name":"The Meducator","volume":"97 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81413306","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}

Specifically, bioinformatic analysis of the changes in cell surface markers and signalling moleculescan help guide our understanding of the timing of cell-fate decisions and regulatory B cell differentiation.

One such inhibitor, pacritinib, targets Janus Kinase 2 (JAK2) to treat patients with myelofibrosis (MF). In MF patients diagnosedwith a specific point mutation (JAK2V61F), the JAK/STAT pathway is over-activated, leading to an increase in cell proliferation rates.Pacritinib restores normal JAK/STAT activity by targeting aberrant activity of JAK2V61F mutant proteins and inhibiting cell proliferation inbone marrow tissue. In recent studies, pacritinib has shown better results at treating MF than the best available therapy. Though pacritinibis a potentially effective treatment option, it does not address all aspects of MF and should be supplemented with other treatments.","PeriodicalId":22813,"journal":{"name":"The Meducator","volume":"57 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78858031","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}

In fact, HIV infection remainsincurable due to a long-lived latent reservoir of HIV within the central nervous system (CNS), as well as the most impervious reservoir, CD4+ T cells. This review evaluates “shock and kill” therapy, an emerging curative strategy thattargets HIV reservoirs. The novel approach aims to “shock” latently infected cells by inducing HIV viral expression through latency reversing agents (LRA). Upon reactivation,the “kill” method refers to the termination of virus-infected cells by employing strategies involving HIV-specific CD8+ T cells. The potential benefits of purging immune cells ofHIV-infected individuals and limiting the size of the latent reservoir must be assessed to advance the “shock and kill” technique.","PeriodicalId":22813,"journal":{"name":"The Meducator","volume":"90 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82049246","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}
