  • Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most common dose-limiting side effects of neurotoxic chemotherapeutic agents that lead to decreased quality of life and dose reduction, delay or even cessation of treatment. The purpose of this systematic review is to evaluate the effect and the underlying mechanisms of bee venom (BV) pharmacopuncture therapy for CIPN in animal models. We searched for the available experimental literature using BV for CIPN through the Pubmed databases. Ten experimental studies were finally included in this review. In the oxaliplatin or paclitaxel-induced CIPN animal model, BV significantly relieved pain caused both mechanical and cold stimulation. It was suggested that the effect of BV is mediated by the stimulation effect of spinal α1- and α2-adrenergic receptors as a potential mechanism. In the future, more experimental studies are needed.

  • Liquid sloshing constitutes a broad class of problems of great practical importance with regard to the safety of liquid transportation systems, such as tank trucks on highways, liquid tank carriages on rail roads, ocean going vessels and propellant tanks in liquid rocket engines. The present work attempts to give a review of some selected experimental investigations carried out during the last couple of decades. This paper highlights the various parameters attributed to the cause of sloshing followed by effects of baffles, tank inclination, magnetic field, tuned liquid dampers, electric field etc. Further, recent developments in the study of sloshing in micro and zero gravity fields have also been reported. In view of this, fifteen research articles have been carefully chosen, and the work reported therein has been addressed and discussed. The key issues and findings have been compared, tabulated and summarized.

  • Utilization of small robots in psychology and biology provides a new breakthrough in understanding the neurobiological mechanisms of various animal behavior. The expansion of robot use in animal research is partly due to increased availability of economically plausible mobile robots and also due to the current shift in animal research toward more ecologically valid experiments. Ground-breaking experimental findings are expected when the behavioral variables are manipulated in more natural situations. In addition, the results from laboratory could be generalized more easily with added ecological validity. The current paper attempts to review a wide range of applications of animal robots used to study animal behavior and to highlight major advantages and limitations. In particular, this review focuses more on the psychological impact of animal robots than engineering details about their structure and operation. Finally, this review will provide some practical considerations when employing robots in animal experiments.

  • Forward head posture (FHP) is a musculoskeletal disorder that causes neck pain. Several exercise interventions have been used in South Korea to improve craniovertebral angle (CVA) and relieve neck pain. There has been no domestic literature review study over the past 5 years that has investigated trends and effects of exercise intervention methods for CVA with neck pain. This domestic literature review aimed to evaluate the trends and effects of exercise interventions on CVA and neck pain in persons with FHP. A review of domestic literature published in Korean or English language between 2018 and 2022 was performed. Literature search was conducted on Google Scholar and Korea Citation Index by using the following keywords: "exercise," "exercise therapy," "exercise program," "forward head posture," and "neck pain." Ten studies were included in this review. All of the studies showed positive improvements after intervention programs that included exercises. Notably, four of these studies demonstrated significant differences in results between the experimental and control groups. Among the 10 studies, nine measured visual analogue scale or numerical rating scale scores and reported significant reductions in pain following interventions, including exercise programs. Five of these studies showed significant differences in results between the experimental and control groups. Furthermore, six studies that used neck disability index exhibited a significant decrease in symptoms after implementing intervention programs that included exercise, and significant differences in results were found between the experimental and control groups. This domestic literature review provides consistent evidence to support the application of various exercise intervention programs to improve CVA and relieve neck pain from FHP. Further studies are warranted to review the effects of various exercise interventions on FHP reported not only in domestic but also in international literature.

  • Purpose: Rodent models have emerged as an alternative to established larger animal models for peri-implantitis research. However, the construct validity of rodent models is controversial due to a lack of consensus regarding their histological, morphological, and biochemical characteristics. This systematic review sought to validate rodent models by characterizing their morphological changes, particularly marginal bone loss (MBL), a hallmark of peri-implantitis. Methods: This review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. A literature search was performed electronically using MEDLINE (PubMed), and Embase, identifying pre-clinical studies reporting MBL after experimental peri-implantitis induction in rodents. Each study's risk of bias was assessed using the Systematic Review Center for Laboratory animal Experimentation (SYRCLE) risk of bias tool. A meta-analysis was performed for the difference in MBL, comparing healthy implants to those with experimental peri-implantitis. Results: Of the 1,014 unique records retrieved, 23 studies that met the eligibility criteria were included. Peri-implantitis was induced using 4 methods: ligatures, lipopolysaccharide, microbial infection, and titanium particles. Studies presented high to unclear risks of bias. During the osseointegration phase, 11.6% and 6.4%-11.3% of implants inserted in mice and rats, respectively, had failed to osseointegrate. Twelve studies were included in the meta-analysis of the linear MBL measured using micro-computed tomography. Following experimental peri-implantitis, the MBL was estimated to be 0.25 mm (95% confidence interval [CI], 0.14-0.36 mm) in mice and 0.26 mm (95% CI, 0.19-0.34 mm) in rats. The resulting peri-implant MBL was circumferential, consisting of supra- and infrabony components. Conclusions: Experimental peri-implantitis in rodent models results in circumferential MBL, with morphology consistent with the clinical presentation of peri-implantitis. While rodent models are promising, there is still a need to further characterize their healing potentials, standardize experiment protocols, and improve the reporting of results and methodology.

  • Objective: The endpoint of this review is to investigate existing studies of Cervi cornu parvum (CCP) pharmacopuncture within Korean medicine journals in order to present a better research method in the future. Methods: We searched all the papers through six Korean electrical databases that included the title of "Cervi cornu parvum pharmacopuncture" or "Cervi cornu parvum aqua-acupuncture". Articles that had been published until December 2012 were largely divided into experimental studies and clinical studies. Results: Fifty-three (53) experimental studies and six clinical studies were found. The number of published articles has been constantly increasing. Many of the experimental studies demonstrated anti-inflammatory effects for arthritis, and most of the clinical studies dealt with musculoskeletal problems. Conclusion: Various therapeutically significant effects of the CCP pharmacopuncture have been found through this review; however, more systematic clinical studies on the CCP pharmacopuncture seem to be necessary to substantially support its clinical effects.

  • This study was conducted to examine the current status of traditional korean medicine studies on gastroesophageal reflux disease in Korea, identify deficiencies, and suggest the direction of future medicine research methods to lay the foundation for traditional korean medicine treatment. All domestic papers on the korean traditional treatment of gastroesophageal reflux disease were selected among the literature published until August 2022 in six domestic databases. A total of 52 selected research data were classified into experimental research papers, clinical research papers, and review papers. In experimental papers, to evaluate the effectiveness of treatment, improvement of esophageal mucosal lesions, anti-inflammatory mechanisms, antioxidant mechanisms, esophageal mucosal protection mechanisms, gastric peristalsis control, and gastric acid secretion inhibition mechanisms were used as evaluation measures. In the clinical research paper, the basis for diagnosis of cases was clinical symptoms through medical history listening and diagnosis through visits to hospitals in the past. The average treatment period was 40.7 days, and the duration of treatment was not significantly affected by the duration of the disease. The most widely used Korean medicine treatment intervention was herbal medicine. There were 3 literature review studies, 3 systematic literature review and meta-analysis studies, 1 comparative review study for clinical trial guideline development, all using Chinese papers. This study included all domestic papers on gastroesophageal reflux disease to identify the research trend of the Korean oriental medicine community, and based on this, it is meaningful to confirm areas that need to be supplemented in future research plans.

  • Purpose: This study was done to evaluate the effects of a short-term life review on spiritual well-being, depression, and anxiety in patients with terminal cancer. Methods: The study used a pre posttest quasi experimental design with a nonequivalent control group. Measurement instruments included the Functional Assessment of Chronic Illness Therapy-Spiritual scale (FACIT-Sp12) and the Hospital Anxiety and Depression Scale (HADS). Participants were 32 patients with terminal cancer who were receiving chemotherapy or palliative care at hospitals or at home. Eighteen patients were assigned to the experimental group and 14 to the control group. A sixty minute short-term life review session was held twice a week as the intervention with the experimental group. Results: There was a statistically significant increase in spiritual well-being in the experimental group compared to the control group. There were also significant decreases in depression and anxiety in the experimental group compared to the control group. Conclusion: The results indicate that a short-term life review can be used as a nursing intervention for enhancing the spiritual well-being of patients with terminal cancer.
