  • Background: The application of Kinesio tape (KT) has become an alternative treatment for the reduction of edema owing to its distinct characteristics that mimic skin behavior. Although many studies have found that KT application has a positive effect on edema related to breast cancer and rehabilitation following mandibular third molar surgery, there is little evidence to support the use of KT for musculoskeletal injuries. Objects: The purpose of this study was to review the literature related to KT application for reducing edema caused by musculoskeletal disorders. Methods: A literature search (July 2022) was performed on PubMed for articles published between January 2012 and June 2022. The following keywords were used: "Kinesio taping," "Kinesio tape," "swelling," and "edema," with different combinations and derivations. Only articles available in English were included in this study. Results: Among 68 identified studies, seven met our search strategy and criteria and were included in the literature review. Five of these studies investigated musculoskeletal disorders of the knee joint; two of them reported that KT application had a positive effect on edema measured using perimetry following total knee replacement and anterior cruciate ligament reconstruction. However, the KT application did not improve swelling in patients with acute lateral ankle sprains. Pediatric patients with acute proximal phalangeal joint sprain experienced a more significant improvement in the reduction of swelling than the group using a splint. Conclusion: This literature review found discrepant evidence to support using KT for edema control in musculoskeletal disorders. Further research is needed to determine the effectiveness of KT for controlling edema following musculoskeletal injuries.

  • Bisphosphonates, estrogen, and calcium supplements are commonly used medications for postmenopausal osteoporosis, but they are associated with various side effects such as vaginal bleeding, deep vein thromembolism, and breast cancer. In this study, we aimed to investigate the potential of a compound isolated from the roots of Oryza sativa L. to improve osteoporosis using an ovariectomized mouse model. We isolated and identified oryzativol A, a lignan compound, through chemical analysis of an ethanol extract using a bioassay-guided fractionation protocol. We also examined the metabolism, clearance, and CYP enzyme activity of oryzativol A, and found that it showed plasma stability of over 80% at all analysis times, and indicating a low likelihood of inactivation or excretion by the CYP3A4 enzyme. Our results showed that the high-dose group of oryzativol A exhibited a significant increase in bone mineral density compared to the control group. Although the ALP concentration did not differ significantly compared to the control group, it showed a tendency to increase in the high-dose group of oryzativol A. Furthermore, the abnormal ratio of serum Ca/P, caused by osteoporosis, was improved to a level closer to that of the normal group as the dosage of oryzativol A increased. Taken together, these findings suggest that oryzativol A is stable in vivo and has potential as a therapeutic agent for osteoporosis, particularly when administered in high doses.

  • The global increase in multidrug-resistant (MDR) bacteria has inspired researchers to develop new strategies to overcome this problem. In this study, 23 morphologically different, soil-isolated actinomycete cultures were screened for their antibacterial ability against MDR isolates of ESKAPE pathogens. Among them, isolate BOGE18 exhibited a broad antibacterial spectrum, so it was selected and identified based on cultural, morphological, physiological, and biochemical characteristics. Chemotaxonomic analysis was also performed together with nucleotide sequencing of the 16S rRNA gene, which showed this strain to have identity with Streptomyces lienomycini. The ethyl acetate extract of the cell-free filtrate (CFF) of strain BOGE18 was evaluated for its antibacterial spectrum, and the minimum inhibitory concentration (MIC) ranged from 62.5 to 250 ㎍/ml. The recorded results from the in vitro anti-biofilm microtiter assay and confocal laser scanning microscopy (CLSM) of sub-MIC concentrations revealed a significant reduction in biofilm formation in a concentration-dependent manner. The extract also displayed significant scavenging activity, reaching 91.61 ± 4.1% and 85.06 ± 3.14% of 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), respectively. A promising cytotoxic ability against breast (MCF-7) and hepatocellular (HePG2) cancer cell lines was obtained from the extract with IC50 values of 47.15 ± 13.10 and 122.69 ± 9.12 ㎍/ml, respectively. Moreover, based on gas chromatography-mass spectrometry (GC-MS) analysis, nine known compounds were detected in the BOGE18 extract, suggesting their contribution to the multitude of biological activities recorded in this study. Overall, Streptomyces lienomycini BOGE18-derived extract is a good candidate for use in a natural combating strategy to prevent bacterial infection, especially by MDR pathogens.

  • A 63-year-old female patient was admitted to the hospital with complaints of coldness in the head and right femur, persistent vertigo, dry mouth, vexation, general weakness, anorexia, and hot flashes. After being diagnosed with left-sided ductal carcinoma in 2017 and undergoing partial resection, she was recommended radiotherapy, chemotherapy, and hormone therapy, but she refused and did not receive any treatment. At a checkup in November 2022, the left-sided invasive ductal carcinoma recurred. She underwent partial resection and was scheduled to receive radiotherapy two months later. During hospitalization, the patient received traditional Korean medicine treatment, including Korean herbal medicine (Osuyubujaijung-tang), acupuncture, moxibustion, and cupping. Subjective symptom changes were evaluated daily. At discharge, the patient's symptoms improved, and her condition varied with the presence of Aconitum carmichaelii. This study suggests that "Osuyubujaijung-tang" cared the coldness and vertigo caused by "Han-dam (寒痰)" in patients with Soeumin visceral syncope pattern (少陰人 臟厥症) and that A. carmichaelii played a major role in this outcome.

  • Purpose: This scoping review investigated the content and quality of YouTube videos on women's health. Methods: A literature search of the Cochrane Library, PubMed, Embase, CINAHL, ERIC, and RISS databases was performed using the keywords "('youtube'/exp OR youtube OR 'social media'/exp OR 'social media' OR (('social'/exp OR social) AND ('media'/exp OR media))) AND ('female health care' OR (('female'/exp OR female) AND ('health'/exp OR health) AND ('care'/exp OR care)))" from February 21 to 27, 2023. Peer-reviewed analytic studies in English or Korean that focused on women's health using YouTube were included. Results: The review identified 21 articles that covered various themes related to women's health, such as breast cancer, urinary disease, sexual health, pelvic organ prolapse, the human papillomavirus vaccine, Papanikolaou smears, contraception, women's health information during the coronavirus disease 2019 pandemic, obstetric epidural anesthesia, and placenta accreta. However, the overall quality of the content was low, inaccurate, unreliable, and misleading. Conclusion: This scoping review demonstrated that YouTube videos on women's health covered diverse topics, but the quality of the content needed improvement. More reliable and high-quality videos produced by academic institutes and healthcare professionals specializing in women's health are needed for social media to be usable as a reliable source of women's health information. The high number of views and shares received by the videos underscores the importance of providing accurate and reliable information on women's health.

  • At a recent medical imaging technology, the major issue of X-ray diagnosis in breast cancer is the early detection of breast cancer and low patient's exposure dose. As one of studies to acquire a monochromatic X-ray, Technologies using multilayer mirror had been preceded. However, a uniform multilayer mirror that consists of uniform thin-film thickness can acquire a monochromatic X-ray only in the partial area corresponds to angle of incidence of white X-ray, so there are limits for X-ray imaging technology applications. In this study, we designed laterally graded multilayer mirror(below GML) that reflects same monochromatic X-ray over the entire area of thin-film mirror, which have the the thickness of the linear gradient that correspond to angle of incidence of white X-ray. By using ion-beam sputtering system added the mask control system we fabricated a GML which has size of $100{\times}100mm^2$. The GML is designed to achieve the monochromatic X-ray of 17.5kev energy and has thin-film thickness change from 4.62nm to 6.57nm(3.87nm at center). It reflects the monochromatic X-ray with reflectivity of more than 60 percent, FWHM of below 2.6keV and X-ray beam width of about 3mm. The monochromatic X-ray corresponded to 17.5keV using GML would have wide application in development of mammography system with high contrast and low dose.

  • Some phytoestrogens in soy and red wine, for example, might have beneficiary rather than adverse effects. In particular, dietary soy intake seems to be highly correlated with protection of breast cancer, osteoporosis and cardiovascular disorders. However, questions persist on the potential adverse effects of the main soy constituent genistein (GS) on female reproductive physiology. Previously we found that prepubertal exposure to GS could activate the reproductive system of immature female rats leading to precocious puberty onset, and intracerebroventricularly (ICV) injected GS could directly activate hypothalamic kisspeptin-GnRH neuronal circuits in adult female rats. The present study was performed to examine the hypothalamus-specific GS effects in prepubertal female rats and which subtype of estrogen receptor is mediated in this GS effect. Prepubertal female rats (PND 30) were anaesthetized, treated with single dose of GS (3.4 ${\mu}g$/animal), and sacrificed at 2 hrs post-injection. To determine the transcriptional changes of reproductive hormone-related genes in hypothalamus, total RNAs were extracted and applied to the semi-quantitative reverse transcription polymerase chain reaction (RT-PCR). ICV infusion of GS significantly lowered the transcriptional activities of mTOR (1:$0.361{\pm}0.058$ AU, p<0.001) but increased that of GAD67 (1:$1.285{\pm}0.099$ AU, p<0.05), which are known to act as an upstream modulator of kisspeptin and GnRH neuronal activities in the hypothalamus, respectively. GS administration enhanced significantly the mRNA levels of KiSS-1(1:$1.458{\pm}0.078$ AU, p<0.001), and exerted no effect on the mRNA level of kisspeptin receptor GPR-54 (1:$1.29{\pm}0.08$ AU). GnRH gene expression was significantly decreased in GS-treated group compared to control group (1:$0.379{\pm}0.196$ AU, p<0.05). There was no difference in the mRNA level of $ER{\alpha}$ in the GS-treated group compare to control group (1:$1.180{\pm}0.390$ AU, Fig. 3A). However, icv infusion of GS significantly increased the transcriptional activities of $ER{\beta}$ (1:$4.209{\pm}0.796$ AU, p<0.01, Fig. 3B). Taken together, the present study indicated that the acute exposure to GS could directly alter the hypothalamic GnRH modulating system in prepubertal female rats. Our study strongly suggested the involvement of $ER{\beta}$ pathway in GS's hypothalamus-specific action, and this idea is consistent with the GS's well-known $ER{\beta}$-mediated protective action in breast cancer.

  • Purpose: Post-mastectomy radiotherapy (PMR) is known to decrease loco-regional recurrence. Adequate skin and dermal dose are achieved by adding bolus. The more difficult clinical issue is determining the necessary number of bolus treatment, given the limits of normal skin tolerance. The aim of this study is to evaluate the necessary number of bolus treatment after PMR in patients with breast cancer. Materials and Methods: Four female breast cancer patients were included in the study. The median age was 53 years(range, $38{\sim}74$), tumor were left sided in 2 patients and right sided in 2patients. All patients were treated with postoperative radiotherapy after MRM. Radiotherapy was delivered to the chest wall (C.W) and supraclavicular lymph nodes (SCL) using 4 MV X-ray. The total dose was 50 Gy, in 2 Gy fractions (with 5 times a week). CT was peformed for treatment planning, treatment planning was peformed using $ADAC-Pinnacles^3$ (Phillips, USA) for all patients without and with bolus. Bolus treatment plans were generated using image tool (0.5 cm of thickness and 6 cm of width). Dose distribution was analyzed and the increased skin dose rate in the build-up region was computed and the skin dose using TLD-100 chips (Harshaw, USA) was measured. Results: No significant difference was found in dose distribution without and with bolus; C.W coverage was $95{\sim}100%$ of the prescribed dose in both. But, there was remarkable difference in the skin dose to the scar. The skin dose to the scar without and with bolus were $100{\sim}105%\;and\;50{\sim}75%$. The increased skin dose rates in the build-up region for Pt. 1, Pt. 2. Pt. 3 and Pt. 4 were 23.3%, 35.6%, 34.9%, and 41.7%. The results of measured skin dose using TLD-100 chips in the cases without and with bolus were 209.3 cGy and 161.1 cGy, 200 cGy and 150.2 cGy, 211.4 cGy and 160.5 cGy, 198.6 cGy and 155.5 cGy for Pt. 1, Pt. 2, Pt. 3, and Pt. 4. Conclusion: It was concludes through this analysis that the adequate number of bolus treatments is 50-60% of the treatment program. Further, clinical trial is needed to evaluate the benefit and toxicity associated with the use of bolus in PMR.

  • Purpose : Measurement of transmission dose is useful for in vivo dosimetry. In this study, previous algorithm for estimation of transmission dose was modified for use in cases with tissue deficit. Materials and Methods : The beam data was measured with flat solid phantom in various conditions of tissue deficit. New algorithm for correction of transmission dose for tissue deficit was developed by physical reasoning. The algorithm was tested in experimental settings with irregular contours mimicking breast cancer patients using multiple sheets of solid phantoms. Results : The correction algorithm for tissue deficit could accurately reflect the effect of tissue deficit with errors within ${\pm}1.0\%$ in most situations and within ${\pm}3.0\%$ in experimental settings with irregular contours mimicking breast cancer treatment set-up. Conclusion : Developed algorithm could accurately reflect the effect of tissue deficit and irregularly shaped body contour on transmission dosimetry.

  • Citrus unshiu peel extracts possess a variety of beneficial effects, and studies on their anticancer activity have been reported. However, the exact mechanisms underlying this activity remain unclear. In the current study, the apoptotic effect of ethanol extract of C. unshiu peel (EECU) on human breast adenocarcinoma MDA-MB-231 cells and related mechanisms were investigated. The results showed that the survival rate of MDA-MB-231 cells treated with EECU was significantly inhibited in a concentration-dependent manner, which was associated with the induction of apoptosis. EECU-induced apoptosis was associated with the activation of caspase-8 and caspase-9, which initiate extrinsic and intrinsic apoptosis pathways, respectively, and caspase-3, a representative effect caspase. EECU suppressed the expression of the inhibitor of apoptosis family of proteins, leading to an increased Bax/Bcl-2 ratio and proteolytic degradation of poly (ADP-ribose) polymerase. EECU also enhanced the loss of the mitochondrial membrane potential and cytochrome c release from the mitochondria to the cytosol, along with truncation of Bid. In addition, EECU activated AMP-activated protein kinase (AMPK), and compound C, an AMPK inhibitor, significantly weakened EECU-induced apoptosis and cell viability reduction. Furthermore, EECU promoted the generation of reactive oxygen species (ROS), which acted as upstream signals for AMPK activation as pretreatment of cells, with the antioxidant N-acetyl cysteine reversing both EECU-induced AMPK activation and apoptosis. Collectively, these findings suggest that EECU inhibits MDA-MB-231 adenocarcinoma cell proliferation by activating intrinsic and extrinsic apoptotic pathways, which was mediated through ROS/AMPK-dependent pathways.
