Technology-enhanced learning in Pharmacology through non-linear storytelling 通过非线性叙事技术强化药理学学习
Christina Elliott
There is a growing body of literature highlighting the potential of game-based learning (GBL) in creating immersive, highly engaging, active learning experiences. Furthermore, advances in digital technology along with the demand for online learning during the COVID-19 pandemic has brought digital GBL to the forefront of innovative teaching practice. Here, I share some of the digital GBL strategies we have developed to support our pharmacology teaching. In collab¬oration with our students, we have co-created a series of “choose your own adventure” style games using Twine; an open-source storytelling game engine. Importantly, we have shown that adoption of these GBL approaches is highly effective in promoting student engagement, subject understanding, and learning community. Furthermore, I also dis¬cuss how AI tools can allow educators with little knowledge or experience of game development to create unique and engaging learning experiences for their students.
越来越多的文献强调了基于游戏的学习(GBL)在创造身临其境、高度参与和积极学习体验方面的潜力。此外,数字技术的进步以及 COVID-19 大流行期间对在线学习的需求,将数字 GBL 推向了创新教学实践的前沿。在此,我将与大家分享我们为支持药理学教学而开发的一些数字化 GBL 策略。在与学生的合作中,我们使用 Twine(一种开源故事游戏引擎)共同创建了一系列 "选择你自己的冒险 "风格的游戏。重要的是,我们已经证明,采用这些 GBL 方法在促进学生参与、学科理解和学习社区方面非常有效。此外,我还讨论了人工智能工具如何让缺乏游戏开发知识或经验的教育工作者为学生创造独特而有吸引力的学习体验。

Inorganic polymers as drug carriers: opportunities and challenges 作为药物载体的无机聚合物:机遇与挑战
B. Divband
Innovative methods and significant developments in designing new synthetic inorganic materials have been used to overcome limitations of current drug delivery systems. Inorganic polymers are widely used in the field of biomedicine, imaging, tissue engineering and drug delivery because of their bioactivity, biocompatibility, and stability. A few of the more well-known wholly inorganic polymers are portland cement, silicon dioxide, polyanionic glasses (including titania- and aluminosilicate glasses), poly(sulphur nitride), polycrystalline diamond, graphite, poly(sulphur nitride), and alumi¬num-silicate materials. Inorganic polymers, especially those possessing significant porosity, are good potential candi¬dates for the delivery of several drugs (anticancer, antibiotics, and anti-inflammatories), providing advantages such as encapsulation, controlled delivery, and improved targeting of drugs. Choosing a suitable drug carrier with a selec¬tive targeting potential also seems to be a very promising way for improving stability as well as selectivity. Despite all the advances, developing homogeneous inorganic polymers with narrow molecular weight distributions is a multidis¬ciplinary challenge. The current keynote speech provides a review of the opportunities and challenges of using inor¬ganic polymers as drug carriers.
设计新型合成无机材料的创新方法和重大进展已被用于克服当前给药系统的局限性。无机聚合物因其生物活性、生物相容性和稳定性,被广泛应用于生物医学、成像、组织工程和给药领域。比较著名的全无机聚合物有硅酸盐水泥、二氧化硅、聚阴离子玻璃(包括二氧化钛玻璃和硅酸铝玻璃)、聚(氮化硫)、聚晶金刚石、石墨、聚(氮化硫)和硅酸铝材料。无机聚合物,尤其是具有显著孔隙率的无机聚合物,是输送多种药物(抗癌药、抗生素和消炎药)的理想潜在载体,具有封装、控制输送和改善药物靶向性等优点。选择具有选择性靶向潜力的合适药物载体似乎也是提高稳定性和选择性的一种非常有前景的方法。尽管取得了诸多进展,但开发分子量分布窄的均相无机聚合物仍是一项跨学科挑战。本主题演讲回顾了将无机聚合物用作药物载体的机遇与挑战。

Acute decompensated heart failure (ADHF) is a leading cause of hospital admission and many factors are known to precipitate decompensation. We aimed to assess the decompensating factors of heart failure and the management of patients admitted to the emergency department (ED). A total of 107 patients were examined, all diagnosed with ADHF in the ED of the Baghdad Teaching Hospital, from June 2017 to December 2017, and presenting with decom¬pensation (pulmonary oedema, peripheral oedema, and fatigue). The mean patient age was 62.5 ± 9.8 years (range: 43–85 years); the majority of them were in their 7th decade (37.4%), and men were slightly more than women. Hy¬pertension was the most commonly associated comorbidity (68.2%), followed by diabetes mellitus (57.9%), coronary artery disease (51.4%), dyslipidaemia (37.4%), arrhythmia (28%), and chronic obstructive pulmonary disease / asthma (23.4%). The most common presentation was pulmonary oedema (88.8%) followed by peripheral oedema (61.7%), and fatigue (26.2%). Uncontrolled hypertension was the most common precipitating condition for decompen¬sation (58.9%), followed by infection (39.3%), acute coronary syndrome (31.8%), arrhythmia (27.1%), non-compliance (11.2%), and anaemia (2.8%). The majority of the admitted patients were managed with intravenously-administered (i.v.) diuretics (92.5%) that may have been combined with oxygen therapy (63.6%), antibiotics (58.9%), β-blockers (50.5%), nitroglycerin (40.2%), i.v. fluids (38.3%), and/or digoxin (19.6%).
急性失代偿性心力衰竭(ADHF)是导致患者入院的主要原因之一,目前已知有许多因素会诱发失代偿。我们的目的是评估心力衰竭的失代偿因素以及对急诊科(ED)入院患者的管理。2017年6月至2017年12月,巴格达教学医院急诊科共收治了107名被确诊为ADHF的患者,他们都出现了失代偿现象(肺水肿、外周水肿和乏力)。患者的平均年龄为(62.5±9.8)岁(范围:43-85岁);大多数患者处于第7个十年(37.4%),男性略多于女性。高血压是最常见的合并症(68.2%),其次是糖尿病(57.9%)、冠心病(51.4%)、血脂异常(37.4%)、心律失常(28%)和慢性阻塞性肺病/哮喘(23.4%)。最常见的症状是肺水肿(88.8%),其次是外周水肿(61.7%)和疲劳(26.2%)。未得到控制的高血压是最常见的致病因素(58.9%),其次是感染(39.3%)、急性冠状动脉综合征(31.8%)、心律失常(27.1%)、不遵医嘱(11.2%)和贫血(2.8%)。大多数入院患者都接受了静脉注射利尿剂(92.5%),并可能同时使用氧疗(63.6%)、抗生素(58.9%)、β-受体阻滞剂(50.5%)、硝酸甘油(40.2%)、静脉输液(38.3%)和/或地高辛(19.6%)。

Phytochemical screening and antimicrobial activity of some medicinal plants 一些药用植物的植物化学筛选和抗菌活性
Alaa Hamady Obeid Al-Taei, R. Saleh, S. Kadhum, A. Omran, R. M. Ewadh, H. H. Owadh
The antimicrobial activity of the aqueous and ethanolic extracts of Myrtus communis, Ammi visnaga, and Equisetum arvense was investigated against Staphylococcus aureus, Escherichia coli, and Candida albicans by using the agar well diffusion method. Serial concentrations (15%, 30%, and 50%) of the extracts of each plant were tested and compared with gentamicin (10 μg) and fluconazole (25 μg). Most of the extract concentrations showed a relatively high antimicrobial activity against all the tested microbes, and the ethanolic extract was more effective than the aque¬ous extract. The activity of plant extracts increased with the increasing extract concentration of Myrtus communis, which appeared to possess a more antimicrobial activity than the other plants assessed; in fact, its ethanolic extract exhibited the highest inhibition zone against S. aureus (32 mm). The ethanolic plant extracts at a concentration of 50% displayed the maximum activity against the herein assessed isolates. Moreover, E. coli showed a higher sensi¬tivity to most extracts, while the lowest effect being noticed on C. albicans.
采用琼脂井扩散法研究了桃金娘、Ammi visnaga 和马钱子的水提取物和乙醇提取物对金黄色葡萄球菌、大肠杆菌和白色念珠菌的抗菌活性。测试了每种植物提取物的序列浓度(15%、30% 和 50%),并与庆大霉素(10 微克)和氟康唑(25 微克)进行了比较。大多数浓度的提取物对所有测试微生物都显示出较高的抗菌活性,乙醇提取物比水提取物更有效。随着香桃木提取物浓度的增加,植物提取物的活性也随之增加,香桃木的抗菌活性似乎高于其他被评估的植物;事实上,其乙醇提取物对金黄色葡萄球菌的抑制区最大(32 毫米)。浓度为 50%的植物乙醇提取物对所评估的分离物具有最大的活性。此外,大肠杆菌对大多数提取物的敏感性较高,而对白喉杆菌的作用最低。

Mazin J. Mousa, H. A. Al-Hindy, Amir Saheb Al-Mumin
Cystatin C (CysC) levels in patients with multiple myeloma (MM) have been linked to tumour load and outcomes’ prediction. This study aimed at assessing the diagnostic utility of CysC in distinguishing MM patients from controls and advanced stages of MM. In total, 98 MM patients and 57 healthy controls participated in this cross-sectional case-control study. Demographic, clinical, and biochemical data were assessed. The study groups exhibited significantly diverse measures of urea, creatinine, CysC, β2-microglobulin, and lactate dehydrogenase activity. β2-Microglobulin was found to be a reliable predictor for both the MM staging and its diagnosis, but CysC was found to only possess a partial capacity of predicting advanced MM stages. Our results highlight the significance of taking into account many biomarkers in the therapy of MM, so as to achieve effective clinical evaluation. More research is required in order to clarify the CysC implication in the prognosis and management of MM.
多发性骨髓瘤(MM)患者的胱抑素C(CysC)水平与肿瘤负荷和预后有关。本研究旨在评估胱抑素C在区分多发性骨髓瘤患者和对照组以及晚期多发性骨髓瘤方面的诊断作用。共有98名MM患者和57名健康对照者参加了这项横断面病例对照研究。研究人员评估了人口统计学、临床和生化数据。研究组在尿素、肌酐、CysC、β2-微球蛋白和乳酸脱氢酶活性方面表现出明显的差异。研究发现,β2-微球蛋白是预测 MM 分期及其诊断的可靠指标,但 CysC 仅具有预测 MM 晚期的部分能力。我们的研究结果凸显了在治疗 MM 时考虑多种生物标志物以实现有效临床评估的重要性。为了明确CysC在MM预后和治疗中的作用,还需要更多的研究。

Gastric ulcer is the most common health concern due to alcohol consumption, smoking, and physiological stress. An ethanol-induced gastric ulcer in an animal model resembles the pathophysiology of the human ulcer. The present study attempted to detect the protective effects of esomeprazole, curcumin, chitosan, and a mixture of curcumin and chitosan on ethanol-induced gastric ulcers in female rats. The present study included 60 rats with an average weight between 179.1 and 180.3 g, divided into two control groups and four treated groups (esomeprazole, curcumin, chi¬tosan, and mixture), where each group included 10 rats. All groups were treated for 30 days. In order to induce a gastric ulcer, absolute ethanol (2 mL/rat) was given orally to all groups (except the negative control ones) after a period of fasting of 20 h. All animals were sacrificed 5 h later. The gastric ulceration was studied by comparing the volume and the pH of the gastric juice, the ulcer index as well as the protective index. Our results revealed a significant decrease (P<0.05) in the values of the ulcer index and the volume of gastric juice in the esomeprazole-, curcumin-, chitosan-, and mixture-treated rats as compared to those of the positive control group. The value of the gastric juice pH exhibited a significant increase (P<0.05) in these same groups.

Preparation and characterization of azelnidipine-loaded D-α-tocopheryl polyethylene glycol succinate (TPGS) / solutol micelles 阿折地平负载型 D-α-生育酚聚乙二醇琥珀酸酯 (TPGS) / Solutol 胶束的制备与表征
Ali Kathem Ala Allah, Shaimaa Nazar Abd Alhammid
Azelnidipine is a calcium-channel antagonist classified as a “class 2” drug with high permeability and low aqueous solubility. It is used in the treatment of angina pectoris and hypertension without reflex tachycardia. Improvement of the solubility of azelnidipine and increasing drug’s bioavailability can be achieved through the drug encapsulation in solutol / D-α-tocopheryl polyethylene glycol succinate (TPGS) micelles. Six formulas were prepared by direct disso¬lution after using different amounts of solutol and TPGS. TPGS and solutol act as solubilizers, permeation enhancers, and P-glycoprotein inhibitors. The particle size, particle size distribution, zeta potential, and entrapment efficiency were determined. Depending on particle size and entrapment efficiency, formula #6 was selected and subjected to in vitro dilution stability and in vitro release studies. The results obtained showed that formula #6 was the best formula, with a high entrapment efficiency percentage equal to 86.5%±0.58% and a small particle size equal to 21.9±7.75 nm that did not change significantly after dilution up to 100-fold; a fact that reveals the high thermodynamic and kinetic stability of the optimum formula. The formula #6 release profile showed a controlled release of the drug from micelles when compared to plain drug release. Based on these results, polymeric nanomicelles are regarded as a promising delivery system for azelnidipine.
阿折地平是一种钙通道拮抗剂,属于 "2 类 "药物,具有高渗透性和低水溶性。它用于治疗心绞痛和无反射性心动过速的高血压。通过将药物封装在 Solutol / D-α-tocopheryl polyethylene glycol succinate(TPGS)胶束中,可以改善阿折地平的溶解度并提高药物的生物利用度。在使用不同量的 Solutol 和 TPGS 后,通过直接分解法制备了六种配方。TPGS 和 Solutol 可用作增溶剂、渗透促进剂和 P 糖蛋白抑制剂。粒度、粒度分布、ZETA电位和夹带效率均已测定。根据粒度和夹带效率,选择了 6 号配方,并进行了体外稀释稳定性和体外释放研究。结果表明,6 号配方是最佳配方,其夹带效率高达 86.5%±0.58%,粒径小至 21.9±7.75 nm,稀释 100 倍后无明显变化,这表明最佳配方具有较高的热力学和动力学稳定性。6 号配方的释放曲线显示,与普通药物释放相比,胶束的药物释放得到了控制。基于这些结果,聚合物纳米胶束被认为是一种很有前景的阿折地平给药系统。

Based on these results, polymeric nanomicelles are regarded as a promising delivery system for azelnidipine.","PeriodicalId":515365,"journal":{"name":"Review of Clinical Pharmacology and Pharmacokinetics - International Edition","volume":"262 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141012958","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}

Regulatory B-cells: immunomodulating mechanisms and important cellular targets underlining immunotherapy by immunoregulation 调节性 B 细胞:免疫调节机制和重要的细胞靶点,通过免疫调节实现免疫治疗
Zaman I. L. Al-Kaabi
Regulatory B-cells (Breg cells) represent as an important modulator of the immune system and their role is unique in autoimmunity, infection, tolerance to transplants, allergy, and cancer. Several regulatory mechanisms exist by which Breg cells can control the function of other immune cells through two main pathways: the secretion of soluble mole¬cules and the use of cell surface-expressed molecules. Anti-inflammatory cytokine interleukin-10 acts as the hallmark of Breg cell function; other cytokines with a similar role include the transforming growth factor-beta and interleukin-35. Breg B cells also release the cytotoxic granzyme B that mediates cell apoptosis. Cell surface-expressed proteins include FasL, CD80, CD86, CD73, CD1d, and PD-L1. The present article reviews the immunosuppressive pathways in order to understand how they emerge and are induced to evoke their regulatory activities, and how we can benefit from them in the field of immunotherapy.
调节性 B 细胞(Breg 细胞)是免疫系统的重要调节因子,在自身免疫、感染、移植耐受、过敏和癌症中发挥着独特的作用。Breg细胞可通过两种主要途径控制其他免疫细胞的功能:分泌可溶性分子和利用细胞表面表达的分子。抗炎细胞因子白细胞介素-10是Breg细胞功能的标志;其他具有类似作用的细胞因子包括转化生长因子-β和白细胞介素-35。Breg B 细胞还会释放细胞毒性颗粒酶 B,介导细胞凋亡。细胞表面表达的蛋白包括 FasL、CD80、CD86、CD73、CD1d 和 PD-L1。本文回顾了这些免疫抑制途径,以了解它们是如何出现和被诱导以唤起其调节活动的,以及我们如何在免疫疗法领域从中获益。

Antibiotic resistance of Bacillus species isolated in foodstuff samples that were collected in Babylon (Iraq) 在巴比伦(伊拉克)采集的食品样本中分离出的芽孢杆菌的抗生素耐药性
Hutham Abdulilah Amer Aladeli, A. Althahab, S. Jabuk
A total of 164 food samples were collected from various supermarkets and farmers in various areas of Babylon, were placed in plastic containers, and were transported to the laboratory. The isolation of Bacillus species was performed by culture in blood agar, chromogenic agar, and the absence of growth on McConkey agar, by staining with Gram stain, and through molecular identification of the species’ 16SrRNA gene and sequencing. The antibiotic susceptibility test used eight types of antibiotics. The undertaken sequencing identified the Bacillus isolates to belong to the follow¬ing species: B. subtilis (2), B. cereus (6), B. thuringiensis (1), B. anthracis (1), and B. spizizenii (1). The susceptibility test of the six B. cereus isolates revealed that 5 (83.3%), 4 (66.6%), 3 (50%), 2 (33.3%), 2 (33.3%), 2 (33.3%), 1 (16.6%), and 0 (0%) were resistant to rifampicin, clindamycin, erythromycin, tetracycline, trimethoprim, nitrofurantoin, gentamicin, and ciprofloxacin, while the respective resistance numbers for the two isolates of B. subtilis were 2 (100%), 2 (100%), 2 (100%), 0 (0%), 1 (50%), 0 (0%), 0 (0%), and 0 (0%). One isolate of B. thuringiensis presented resistance to erythromycin, erythromycin, trimethoprim, and rifampicin, while one isolate of B. anthracis was found to be resistant to gentamicin, erythromycin, nitrofurantoin, and rifampicin. The B. spizizenii isolate was resistant to all antibiotics except gentamicin and trimethoprim.

Applications of quartz crystal microbalance with dissipation in nanomedicine (QCM-D): a personal experience 带耗散的石英晶体微天平在纳米医学中的应用(QCM-D):个人体验
M. Santos-Martinez
Due to their unique physical and chemical properties, the potential application of nanomaterials in medicine is partic¬ularly attractive. Despite the many advantages that nanomaterials can offer as diagnostic and therapeutic tools, their transition from the bench to clinical practice is extremely challenging. One of the many barriers that nanomedicines may encounter is their toxicological effect. In fact, the development of novel nanomaterials / nanoparticles must pro¬ceed always in tandem with the assessment of any potential toxicological effects associated to them. Once nano¬materials reach the systemic circulation, they interact with endothelial cells, plasma proteins, and other blood compo¬nents. There is no doubt that the study of nanomaterials-blood interactions is crucial to warrant the biocompatibility of nanomaterials developed for human use.
由于其独特的物理和化学特性,纳米材料在医学中的潜在应用尤其具有吸引力。尽管纳米材料作为诊断和治疗工具具有诸多优势,但将其从实验室过渡到临床实践却极具挑战性。纳米药物可能遇到的众多障碍之一是其毒理学效应。事实上,在开发新型纳米材料/纳米颗粒的同时,还必须对其潜在的毒理学效应进行评估。纳米材料一旦进入体内循环,就会与内皮细胞、血浆蛋白和其他血液成分发生作用。毫无疑问,研究纳米材料与血液的相互作用对于保证开发用于人类的纳米材料的生物相容性至关重要。
