“…It has been recommended to include at least 30 participants in studies involving parametric tests, the current study inflated the sample size to account for potential data losses. 7 The subjects included furnished written informed consent. The exclusion criteria were: bleeding diathesis, such as haemophilia, severe anaemia with haemoglobin (Hb) <9.5g/dl), use of anticoagulant drugs, such as warfarin, pregnancy and breastfeeding, history of allergies to leeches, chronic kidney failure and dialysis, presence of pacemaker, age <18 years, chemotherapy, active bleeding, like haemorrhoids, normal menstrual cycle, postoperative period, etc., and glycated Hb (HbA1c) >10, or fasting blood sugar (FBS) >250mg/dl.…”

Objective: To examine the influence of hirudotherapy on parameters of oxidative stress. Method: The cross-sectional study was conducted from March 29 to September 29, 2021, at the Alanya Research and Training Hospital’s Traditional and Complementary Medicine Application Centre, Turkey, and comprised adult volunteers of either gender. The participants were subjected to two sessions of hirudotherapy 4 weeks apart. Total antioxidant status, total oxidant status, oxidative stress index values, ischemia-modified albumin level, paraoxonase 1, disulfide, native thiol, total thiol, and arylesterase levels were assessed at baseline and after the second hirudotherapy session. Data was analysed using SPSS 15. Results: Of the 50 subjects, 30(60%) were females and 20(40%) were males. The overall mean age was 47.10±15.16 years. Oxidative stress, ischemia-modified albumin and disulfide levels decreased, but not significantly (p>0.05). The reduction in disulfide levels was significant (p=0.021). Conclusion: Hirudotherapy, within its limitations, could reduce oxidative stress. Key Words: Antioxidant activity, Oxidative stress, Medicinal leeches, Hirudin.

“…The results are presented in units of micromolar hydrogen peroxide equivalent per liter (μmol H2O2 equivalent/L). 7 The ratio of TOS to TAS was used to calculate OSI values. For sums, the resulting unit of TAS was converted to μmol/L, and the OSI value was figured out based on the equation OSI=TOS/TAS.…”

Active learning is a popular approach to teaching and learning that has gained traction through research on STEM educational improvement. There have been numerous university- and national/international-level efforts focused on transitioning courses from the lecture method to active learning. However, despite these large-scale changes, the active learning literature has not been assessed on its methodological rigor to ensure instructional recommendations are rooted in rigorous research studies. The purpose of the present review was to determine areas of strengths and areas in need of improvement and to provide specific recommendations on how to continue or improve active learning research to strengthen the respective literature base and increase confidence in results. We assessed the articles included in the Freeman et al. (PNAS, 111:8410–8415, 2014) meta-analysis as well as a random sample of more recent active learning articles (2015–2022) on 12 internal validity controls (i.e., control procedure used to prevent a threat to the internal validity of a study). Results indicated that there were high percentages of articles that did not meet each internal validity control. In fact, no articles from the Freeman et al. meta-analysis and no sampled 2015–2022 articles met each of the 12 internal validity controls. Therefore, the active learning literature contains numerous internal validity control issues that need to be addressed if we are to determine the extent to which active learning interventions are effective and if there are any boundary conditions for when particular active learning interventions are or are not effective.

The current study aimed to provide a detailed synthesis of the literature on digital mathematics games and to gain an in-depth understanding of the current status of research on digital mathematics games. For this purpose, digital mathematics game articles published in peer-reviewed journals from 2005 to 2023 were systematically reviewed. To locate these articles, the following keywords were searched in TR Index, DergiPark Academic, and Google Scholar: “digital game”, “video game”, “computer game”, “interactive game”, “mobile game”, and “serious game”. The articles retrieved from the search were subjected to a two-stage screening process. First, the titles and abstracts of the articles were examined. Second, their full texts were examined. After the screening process, 26 articles that suited the purpose of the study were determined. Relevant data from the selected articles were extracted manually, recorded in an Excel spreadsheet, and finally synthesized. The findings were reported using the following research trends: (i) research aims, (ii) research methodologies, (iii) research participants, (iv) sample sizes, (v) designers of the digital mathematics games, (vi) environments used for designing digital mathematics games, and (vii) learning domains of the digital mathematics game topics. The findings are discussed based on the literature and implications for stakeholders are presented.
