Beta-blockers (β-blockers) are pharmacotherapeutics that have been used to treat patients with cardiovascular symptoms since their discovery in the 1960s. They work by targeting B1 and B2 receptors which are involved the stress response, which consequently lead to reduced activation of the “flight-or-fight mechanism”. It has also been noticed that β-blockers can be beneficial in treating anxiety disorders and other mental health complications. Currently, the only approved drugs for anxiety and other mental health conditions include benzodiazepines and selective serotonin reuptake inhibitors. Historically, there has been strong resistance to the use of β-blockers in mental health treatment because of the prevalence of depressive symptoms during treatment. Recently, a growing number of studies have seen that there is no strong relationship between β-blockers and depression in patients. Although there are still other adverse effects related to the usage of β-blockers, investigating the relationship between depressive symptoms and β-blockers may suggest a potential therapeutic option in mental health treatments. This review explores the history of β-blockers, their mechanism of action, developments in their use as a mental health treatment and current approved pharmacotherapeutics for mental health.   
-受体阻滞剂(β-阻滞剂)是自20世纪60年代被发现以来用于治疗心血管症状的药物治疗药物。它们通过靶向参与应激反应的B1和B2受体起作用,从而导致“逃跑或战斗机制”的激活减少。人们还注意到β受体阻滞剂对治疗焦虑症和其他精神健康并发症有益。目前,唯一被批准用于治疗焦虑和其他精神疾病的药物包括苯二氮卓类药物和选择性血清素再摄取抑制剂。从历史上看,由于治疗期间抑郁症状的普遍存在,在心理健康治疗中使用β-受体阻滞剂一直存在强烈的阻力。最近,越来越多的研究发现β受体阻滞剂与患者抑郁之间没有很强的关系。尽管仍有其他与β受体阻滞剂使用相关的不良反应,但研究抑郁症状和β受体阻滞剂之间的关系可能为心理健康治疗提供一种潜在的治疗选择。本文综述了β受体阻滞剂的历史、作用机制、心理健康治疗的发展以及目前批准的心理健康药物治疗方法。

Traumatic live events comprise the etiology of post-traumatic stress disorder (PTSD). PTSD patients are known to face adverse impacts on their mental and physical health. Symptoms of concern relating to PTSD include heightened anxiety levels, intrusive memories, nightmares, and problems with sleeping. Disrupted sleep leads to exhausted brain function that impedes the daily activities of individuals and impacts their perceived quality of life. Therefore, researchers have sought to examine interventions that help improve sleep and circadian rhythms. Recently, blue-light therapy has been the target of clinical research to understand its role in alleviating PTSD symptoms. Results from clinical trials showed that patients receiving blue light showed significant reductions in daytime sleepiness and fatigue. Furthermore, these individuals showed faster reaction times and greater phase advances in circadian rhythms, leading to earlier sleep onset at night. As we work towards focusing our attention on addressing mental health issues, investigating the benefits of non-pharmacological interventions such as blue-light therapy can help improve the health outcomes of PTSD patients.
创伤性生活事件构成了创伤后应激障碍(PTSD)的病因。众所周知,创伤后应激障碍患者的心理和身体健康都会受到不利影响。与创伤后应激障碍有关的症状包括高度焦虑、侵入性记忆、噩梦和睡眠问题。睡眠中断会导致大脑功能衰竭,阻碍个人的日常活动,影响他们的生活质量。因此,研究人员试图研究有助于改善睡眠和昼夜节律的干预措施。最近,蓝光疗法已成为临床研究的目标,以了解其在减轻创伤后应激障碍症状中的作用。临床试验结果显示,接受蓝光照射的患者白天嗜睡和疲劳的症状明显减轻。此外,这些人表现出更快的反应时间和更大的昼夜节律阶段进步,导致晚上更早入睡。当我们努力将注意力集中在解决心理健康问题时,研究非药物干预的好处,如蓝光疗法,可以帮助改善创伤后应激障碍患者的健康状况。

Background: Although Science Communication (SciComm) is a growing field, there currently exist a large number of undergraduate- and graduate- level SciComm training programs worldwide. Two noted benefits of such programs are improvement in SciComm confidence and sense of belonging. ComSciConCAN is a graduate level SciComm conference; no studies have previously looked into the impacts of this conference, which encouraged us to initiate this study.    Purpose: To explore the impacts of ComSciConCAN on the participants’ confidence in communicating with other scientists and the general public, and their sense of belonging in their current STEM programs and SciComm activities  Methods: ComSciConCAN-2021 participants were asked to complete pre- and post- workshop surveys. Data analysis was done using Microsoft Excel, and unpaired t-test statistical analysis was conducted (when applicable) using Graphpad. Results: With regards to confidence, significant differences (p < 0.05) were observed in the mean levels reported for all three cases pre- versus post- conference. Regarding sense of belonging, 65% and 83% of the participants reported at least “somewhat agreeing” that the workshops will help improve this in their current STEM program and SciComm activities, respectively.  Conclusion: The conference did have a positive impact on the participants’ SciComm confidence and senses of belonging.
背景:虽然科学传播(sciicomm)是一个不断发展的领域,但目前世界上有大量的本科和研究生水平的sciicomm培训项目。这类项目的两个显著好处是提高了公司的信心和归属感。ComSciConCAN是一个研究生级的sciccomm会议;之前没有研究调查过这次会议的影响,这鼓励了我们开始这项研究。目的:探讨ComSciConCAN对参与者与其他科学家和公众交流的信心,以及他们在当前STEM项目和sciccomm活动中的归属感的影响。方法:ComSciConCAN-2021参与者被要求完成研讨会前和研讨会后的调查。使用Microsoft Excel进行数据分析,使用Graphpad进行非配对t检验统计分析(如适用)。结果:在置信度方面,三个病例在会议前后报告的平均水平上有显著差异(p < 0.05)。在归属感方面,65%和83%的参与者表示至少“在一定程度上同意”研讨会将分别在他们目前的STEM项目和科学管理活动中帮助改善归属感。结论:会议确实对与会者的科学信心和归属感产生了积极的影响。

Alopecia refers to hair loss, which is a common side-effect of chemotherapy regimens for cancer. Anthracyclines and taxanes are the common anticancer drugs prescribed within chemotherapy that result in significant alopecia. Scalp cooling is identified to be an effective method that prevents chemotherapy-induced alopecia (CIA) in patients. This method has been present since 1974; however, novel technologies have enhanced the efficacy via modern scalp-cooling devices. By maintaining a low scalp temperature, vasoconstriction aids in the reduced absorption of anticancer drugs into the bloodstream, which reduces intrafollicular metabolism. Randomized controlled trials conducted recently found statistically significant results, evidencing the hair preservation and hair regrowth abilities yielded via scalp cooling. These results attracted the attention of researchers due to the treatment success and the patient safety aspect of the process. Extensive scientific research reveals that alopecia affects the perceptions of patients regarding their body image and lowers their self-esteem significantly. Furthermore, the quality of life of alopecia patients is reduced due to public stigmatization. The effectiveness of scalp cooling in preventing CIA is of high significance as it can help improve patient outcomes of patients undergoing chemotherapy and their mental well-being.
脱发是指脱发,这是癌症化疗方案的常见副作用。蒽环类药物和紫杉烷类药物是化疗中常见的导致严重脱发的抗癌药物。头皮冷却被认为是预防化疗性脱发(CIA)的有效方法。这种方法自1974年以来一直存在;然而,新技术通过现代头皮冷却装置提高了功效。通过保持较低的头皮温度,血管收缩有助于减少抗癌药物进入血液的吸收,从而减少滤泡内代谢。最近进行的随机对照试验发现了统计上显著的结果,证明头皮冷却可以保护头发和再生头发。这些结果引起了研究人员的注意,因为治疗成功和患者安全方面的过程。广泛的科学研究表明,脱发会影响患者对自己身体形象的看法,并显著降低他们的自尊心。此外,由于公众的污名化,脱发患者的生活质量降低。头皮冷却预防CIA的有效性具有重要意义,因为它可以帮助改善化疗患者的预后和他们的心理健康。

Rising tuberculosis cases are a global health issue that the United Nations Member States have committed to eradicating by 2030. In developed countries such as Canada, TB affects Indigenous populations disproportionately. Inuit people have 300 times greater risk of TB infections compared to non-Indigenous people. Due to Canada's colonial history, Indigenous people remain underrepresented in healthcare. Therefore, this research proposal aims to understand the link between the lack of access to resources, such as knowledge about tuberculosis and the rising TB cases, among Inuit people in Northern Canada. It is hypothesized that due to marginalization and cultural ignorance, preventative measures are not accessible to Inuit people and can influence the high transmission of the disease. Based on the results of the inclusive design of this research, future studies can aim to help voice the concerns of Indigenous people and advocate for their right to access equitable healthcare.
结核病病例不断上升是一个全球健康问题,联合国会员国已承诺到2030年消除这一问题。在加拿大等发达国家,结核病对土著人口的影响尤为严重。因纽特人感染结核病的风险是非土著居民的300倍。由于加拿大的殖民历史,土著人民在医疗保健方面的代表性仍然不足。因此,这项研究计划旨在了解加拿大北部因纽特人缺乏获取资源(例如结核病知识)与结核病病例上升之间的联系。据推测,由于边缘化和文化无知,因纽特人无法采取预防措施,并可能影响疾病的高传播率。基于本研究的包容性设计结果,未来的研究可以旨在帮助表达土著人民的关切,并倡导他们获得公平医疗保健的权利。

Weighing the Benefits and Drawbacks of Testosterone Replacement Therapy 权衡睾酮替代疗法的利弊
Pub Date : 2023-06-02 DOI: 10.15173/sciential.v1i10.3364

Over the last few decades, the discussion surrounding men’s health issues has sparked an increased interest in the treatment of male hypogonadism—the deficiency of testosterone in the body—through testosterone replacement therapy, in order to improve patients’ quality of life. This makes it a worthwhile consideration for further research as many studies do not sufficiently explore the long-term benefits and drawbacks, which may tip the scales on whether it should be prescribed to patients moving forward. It is worth weighing the effects that the treatment offers, as well as examining which patients are most suitable for the therapy and why, from a health cost-benefit analysis. Many of the benefits that this review will touch on relate to the symptoms of hypogonadism, most notably decreased libido, muscle mass, and emotional well-being. This review will also consider the potential side effects of treatment through the investigation of short- and long-term studies that include observational, surveyable, and empirical data. Some of the drawbacks include increased risk of various organ cancers and systemic tissue damage. Holistically, this review will provide insight on the basics of testosterone replacement therapy, who benefits most, who is at risk, and how its understanding can be improved moving forward.
在过去的几十年里,围绕男性健康问题的讨论引发了人们对男性性腺功能减退症(体内睾酮缺乏)治疗的兴趣,通过睾酮替代疗法来提高患者的生活质量。这使得进一步的研究值得考虑,因为许多研究没有充分探索长期的好处和缺点,这可能会影响是否应该给患者开处方。从健康成本效益分析的角度来看,衡量这种疗法的效果,以及检查哪些病人最适合这种疗法,以及为什么适合这种疗法,都是值得的。这篇综述将涉及的许多益处与性腺功能减退的症状有关,最明显的是性欲、肌肉质量和情绪健康的降低。本综述还将通过调查包括观察性、调查性和经验性数据在内的短期和长期研究来考虑治疗的潜在副作用。一些缺点包括各种器官癌症和系统性组织损伤的风险增加。总的来说,这篇综述将提供睾酮替代疗法的基础知识,谁受益最大,谁有风险,以及如何进一步提高对其的理解。

The Effect of Varying Eccentric Velocity on Muscle Hypertrophy 不同偏心速度对肌肉肥大的影响
Pub Date : 2023-06-02 DOI: 10.15173/sciential.v1i10.3339
Muhammad Amjad, Randy Dumont
Resistance training is essential to muscle hypertrophy as it fatigues fibres through time-under-tension (TUT). As myocyte energy depletes, metabolites accrete, leading to inflammation to increase cell size, so it is adapted for future stimuli. TUT can be measured by varying eccentric velocities: i.e., the rate at which a muscle lengthens under load. A longer period of lengthening will lead to greater metabolite accretion and inflammation. However, it is unknown whether TUT is a threshold or if it can gradually increase and lead to more muscle growth. Through a literature review and experiment, this project investigates the effect of varying eccentric velocity on muscle hypertrophy. Previous research in the field of muscle physiology and metabolism were explored, with an emphasis on eccentric training. The supplementary experiment measured shoulder growth in response to the medial deltoid exercise called lateral raises, where different eccentric velocities were assigned to groups. Individualistic daily calorie and protein intake were controlled to ensure that sufficient nutrients were available for recovery and performance. Surprisingly, post-experimental research suggested that high-velocity eccentric training was best for hypertrophy due to greater levels of force production. This was consistent with the experiment, which found that the group with a fast-velocity eccentric, a lower TUT, experienced greater growth. They also exhibited greater strength gain due to neuromuscular junction adaptation. These findings related to TUT are significant for designing exercise regimens that are optimal for the prevention and rehabilitation of musculoskeletal injuries and disorders. The review’s findings suggest that fast-velocity eccentric contractions are ideal for increasing muscle size and strength.
阻力训练对肌肉肥大是必不可少的,因为它使纤维在紧张时间(TUT)下疲劳。随着肌细胞能量消耗,代谢物增加,导致炎症增加细胞大小,因此它适应未来的刺激。TUT可以通过改变偏心速度来测量,即肌肉在负荷下伸长的速度。长时间的延长会导致更大的代谢物增加和炎症。然而,尚不清楚TUT是否是一个阈值,或者它是否会逐渐增加并导致更多的肌肉生长。本项目通过文献综述和实验,探讨不同偏心速度对肌肉肥大的影响。探讨了以往肌肉生理学和代谢领域的研究,重点是偏心训练。补充实验测量了肩部生长对内侧三角肌运动的反应,称为外侧提升,其中不同的偏心速度被分配给各组。个人每天的卡路里和蛋白质摄入量受到控制,以确保有足够的营养物质可供恢复和表现。令人惊讶的是,实验后的研究表明,高速偏心训练对肌肉肥大最有效,因为它能产生更大的力量。这与实验结果一致,实验发现,具有快速偏心的组,TUT较低,经历了更大的增长。由于神经肌肉连接处的适应,它们也表现出更大的力量增益。这些与TUT相关的发现对于设计运动方案具有重要意义,这些方案对于肌肉骨骼损伤和疾病的预防和康复是最佳的。这篇综述的发现表明,快速偏心收缩是增加肌肉大小和力量的理想方法。

As myocyte energy depletes, metabolites accrete, leading to inflammation to increase cell size, so it is adapted for future stimuli. TUT can be measured by varying eccentric velocities: i.e., the rate at which a muscle lengthens under load. A longer period of lengthening will lead to greater metabolite accretion and inflammation. However, it is unknown whether TUT is a threshold or if it can gradually increase and lead to more muscle growth. Through a literature review and experiment, this project investigates the effect of varying eccentric velocity on muscle hypertrophy. Previous research in the field of muscle physiology and metabolism were explored, with an emphasis on eccentric training. The supplementary experiment measured shoulder growth in response to the medial deltoid exercise called lateral raises, where different eccentric velocities were assigned to groups. Individualistic daily calorie and protein intake were controlled to ensure that sufficient nutrients were available for recovery and performance. Surprisingly, post-experimental research suggested that high-velocity eccentric training was best for hypertrophy due to greater levels of force production. This was consistent with the experiment, which found that the group with a fast-velocity eccentric, a lower TUT, experienced greater growth. They also exhibited greater strength gain due to neuromuscular junction adaptation. These findings related to TUT are significant for designing exercise regimens that are optimal for the prevention and rehabilitation of musculoskeletal injuries and disorders. The review’s findings suggest that fast-velocity eccentric contractions are ideal for increasing muscle size and strength.","PeriodicalId":262888,"journal":{"name":"Sciential - McMaster Undergraduate Science Journal","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132446118","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}

Brain cancer, despite being one of the rarest forms of cancer, is one of the most substantially impactful cancers known to humankind. In this review, a comprehensive analysis of the multifaceted nature of brain cancer is conducted, with a particular focus placed on Glioblastoma Multiforme (GBM). Epidemiology, prevention measures, treatment techniques, and determinants of susceptibility are investigated to gain a deeper understanding of GBM. Additionally, the biophysical concepts used in Computed Tomography (CT) scanning for tumour detection are explored. Radiation therapy as a treatment modality for GBM is examined using Intensity Modulated Radiation Therapy (IMRT). Furthermore, the mechanism of action of Temozolomide, the prevailing chemotherapeutic drug used to hinder GBM growth by methylating target DNA sites, was also analyzed. Additionally, a cell survival curve outlining a traditional fractionation schedule of 2.21 Gy installments was created to effectively model a conventional radiation treatment plan. As a result, we are able to gauge the efficacy of such radiation treatments. In summation, we present a broad synopsis of the current strategies, insight, and approaches used to detect, image, and treat the malignant growth of GBM.
脑癌尽管是最罕见的癌症之一,但却是人类已知的影响最大的癌症之一。在这篇综述中,对脑癌的多面性进行了全面的分析,特别关注多形性胶质母细胞瘤(GBM)。流行病学,预防措施,治疗技术和易感性的决定因素进行调查,以获得对GBM更深入的了解。此外,生物物理概念用于计算机断层扫描(CT)扫描肿瘤检测探索。放射治疗作为GBM的一种治疗方式是使用调强放射治疗(IMRT)进行检查。此外,还分析了替莫唑胺的作用机制,替莫唑胺是一种常用的化疗药物,通过甲基化靶DNA位点来抑制GBM的生长。此外,创建了一个细胞存活曲线,概述了传统的2.21 Gy分段分离计划,以有效地模拟传统的放射治疗计划。因此,我们能够评估这种放射治疗的疗效。总之,我们提出了目前的策略,见解和方法,用于检测,成像和治疗GBM的恶性生长的一个广泛的概述。
