Effects of participation in an eight-week, online video body-weight resistance training on cognitive function and physical fitness in older adults: A randomized control trial.

The purpose of this study was to investigate the effects of an eight-week online video bodyweight resistance training on cognitive function and physical fitness in older adults. A total of 30 older adults was randomly assigned into either an exercise group or a control group. The exercise group participated in the exercise and the control group was required to maintain daily living. Mini mental status examination (MMSE) and senior fit-ness tests (SFT) were measured pre- and post-eight weeks of intervention. Participating in the exercise experienced increases in cognitive functions of attention (p < 0.05) and calculation (p < 0.05), recall (p < 0.05), and repetition (p < 0.05) from the MMSE. Also, older adults in the exercise group demonstrated improved two-minute walk (p < 0.05), chair sit tests (p < 0.05), and results of the SFT. The online video resistance training may help to increase cognitive function and fitness in older adults.

Barriers against and strategies for malaria control during the COVID-19 pandemic in low- and middle-income countries: a systematic review.

BACKGROUND: The COVID-19 pandemic has disrupted malaria control activities globally. Notably, high levels of excess malaria morbidity and mortality in low- and middle-income countries (LMICs) were reported. Although it is crucial to systematically understand the main causes of the disruption to malaria control and synthesize strategies to prepare for future pandemics, such studies are scarce. Therefore, this study aims to better identify barriers against and strategies for malaria control. METHODS: Following the PRISMA guidelines and through searches of electronic databases and Google Scholar, a systematic literature review was conducted to identify studies pertaining to malaria control published between January 2020 and December 2021. Only studies that discussed reported barriers and/or strategies related to malaria were included for the review. The Mixed Methods Quality Appraisal Tool (MMAT) and the Authority, Accuracy, Coverage, Objectivity, Date and Significance (AACODS) checklist were used for quality appraisal. Key information such as literature type, study design, setting and population, interventions, outcomes, barriers, and strategies were extracted. With an existing framework of four dimensions (accessibility, affordability, availability, and acceptability) further subdivided by the supply and demand sides, this study synthesized information on barriers and strategies related to malaria control and further categorized the strategies based on the time frame. RESULTS: From the 30 selected studies, 27 barriers and 39 strategies were identified. The lockdown measures, which mainly threatened geographic accessibility and availability of malaria control services, were identified to be the main barrier hindering effective mobilization of community health workers and resources. Among the identified strategies, clear risk communication strategies would alleviate psychosocial barriers, which challenged acceptability. Some strategies that cross-cut points across all four dimensions would, require systems-level integration to enhance availability and affordability of malaria control. The strategies were distinguished between short-term, for instant response, and mid to long-term for future readiness. CONCLUSIONS: The pandemic resulted in complex barriers to malaria control, particularly imposing a double burden on LMICs. Identifying strategies to overcome said barriers provides useful insights in the decision-making processes for the current and future pandemic. Cross-cutting strategies that integrate all dimensions need to be considered. Health system strengthening and resilience strategy appropriate for country-specific context is fundamental.

Intelligent Estimation of Exercise Induced Energy Expenditure Including Excess Post-Exercise Oxygen Consumption (EPOC) with Different Exercise Intensity.

The limited availability of calorimetry systems for estimating human energy expenditure (EE) while conducting exercise has prompted the development of wearable sensors utilizing readily accessible methods. We designed an energy expenditure estimation method which considers the energy consumed during the exercise, as well as the excess post-exercise oxygen consumption (EPOC) using machine learning algorithms. Thirty-two healthy adults (mean age = 28.2 years; 11 females) participated in 20 min of aerobic exercise sessions (low intensity = 40% of maximal oxygen uptake [VO2 max], high intensity = 70% of VO2 max). The physical characteristics, exercise intensity, and the heart rate data monitored from the beginning of the exercise sessions to where the participants' metabolic rate returned to an idle state were used in the EE estimation models. Our proposed estimation shows up to 0.976 correlation between estimated energy expenditure and ground truth (root mean square error: 0.624 kcal/min). In conclusion, our study introduces a highly accurate method for estimating human energy expenditure during exercise using wearable sensors and machine learning. The achieved correlation up to 0.976 with ground truth values underscores its potential for widespread use in fitness, healthcare, and sports performance monitoring.

Physiologic and psychologic adaptation to exercise interventions in lung cancer patients undergoing chemotherapy: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: The purpose of this meta-analysis is to investigate the effectiveness of exercise interventions in patients with lung cancer (LC) during chemotherapy regarding physiological and psychological outcomes. METHODS: Databases including MEDLINE and EMBASE were used to find relevant randomized controlled trails that explored outcomes of exercise interventions for patients with LC during chemotherapy up to June 2020. Effect sizes were calculated by standardized mean difference statistics. RESULTS: Six studies were included that involved 244 participants with average age of 65 years. Patients with LC participating in exercise interventions during chemotherapy had significantly increased strength, forced expired volume, and quality of life as well as significantly decreased pain. Effective exercise intervention characteristics were combined aerobic and resistance exercise, performance more than 5 times a week, moderate to vigorous intensity, and 1-h sessions. CONCLUSION: Supervised participation in exercise improves strength, forced expired volume, and quality of life and relieves pain and depression during chemotherapy.

Influence of Cardiorespiratory Fitness on Risk of Dementia and Dementia Mortality: A Systematic Review and Meta-Analysis of Prospective Cohort Studies.

The purpose of this meta-analysis was to investigate the influence of cardiorespiratory fitness (CF) levels on dementia risk and dementia mortality. MEDLINE and EMBASE databases were used to search for eligible studies from January 1990 to September 2019. To be included, the study was required to be a prospective cohort study that provided CF measurements and indicated relative risk and confidence intervals for the associations between CF and dementia risk and mortality. A total of six studies were selected for this meta-analysis. Low-level CF was associated with nearly three times greater risk of dementia (2.93, 95% confidence interval [1.31, 6.57]; p < .05) compared with a high-level CF. Enhanced CF levels decreased the risk of dementia, and an increase of one metabolic equivalent of task in the CF level reduced the risk of dementia and dementia mortality. Maintaining more than 12 metabolic equivalents of task of CF level was required to substantially decrease dementia risk and dementia mortality.

Influences of exercise interventions on overweight and obesity in children and adolescents.

PURPOSE: Conflicting findings of the effects of exercise on body fat, free fat mass, insulin, insulin resistance, and physical fitness for overweight and obesity in children and adolescents. The purpose of this meta-analysis was to investigate the effects of exercise interventions in children and adolescents with overweight and obesity depending on exercise type and to build effective exercise interventions to reduce risks of metabolic disorders. METHODS: Databases were used to find eligible studies regarding the effects of exercise interventions on overweight and obesity in children and adolescents in randomized controlled trails. Effect size was calculated using the standardized mean difference statistic and heterogeneity across studies was estimated using the Q statistic. RESULTS: A total of 27 studies met the inclusion criteria. Children and adolescents with overweight and obesity who participated in aerobic exercise had reduced body mass index, % body fat, fasting insulin, free fat mass, TNF-α, and IL-6, and increased physical fitness compared with control groups. Reduced free fat mass in resistance exercise was not found. Glucose, insulin resistance, blood pressure, C-reactive protein (CRP), and blood markers including total cholesterol (TC), triglyceride, LDL, and HDL did not have significant change. Average exercise interventions were aerobic exercise, 3 times/week, 60 min, and 36 weeks of exercise period. CONCLUSIONS: Aerobic exercise may be beneficial to reduce body fat, fasting insulin, and inflammatory markers, and increased physical fitness for overweight and obesity in childhood and adolescence, but resistance exercise may be added, which can help avoid muscle loss in children and adolescents with overweight and obesity.

Associations Between Handgrip Strength and Disease-Specific Mortality Including Cancer, Cardiovascular, and Respiratory Diseases in Older Adults: A Meta-Analysis.

Several controversial studies linking handgrip strength and health have suggested that low handgrip strength in older adults may be related to health problems and have investigated whether there is a minimum handgrip strength level associated with reduced mortality. Thus, by meta-analysis, the authors identified an association between handgrip strength in older adults and disease-specific mortality and all-cause mortality. Thirty studies with a total of 194,767 older adult participants were included in this meta-analysis. Higher handgrip strength was associated with an 18% decrease in all-cause mortality. Lower handgrip strength was associated with increased all-cause mortality. The minimum handgrip strength in older women that did not increase all-cause mortality was 18.21 kg. Increased handgrip strength showed a decreased all-cause mortality, whereas decreased handgrip strength was associated with increased all-cause mortality. Strengthening the handgrip may help improve disease-specific mortality in older adults.

Determining the association between physical activity prior to conception and pregnancy rate: A systematic review and meta-analysis of prospective cohort studies.

We investigated the association between physical activity (PA) before pregnancy and pregnancy rate according to intensity and amount of exercise. Eleven prospective cohort studies were included in this meta-analysis. Any amount of moderate-intensity PA was associated with a statistically higher rate of pregnancy compared to that in patients with no PA (p < .05). Any amount of vigorous PA was associated with decreased pregnancy rate; regular PA was associated with decreased infertility (p > .05). In contrast, vigorous PA was associated with increased infertility (p > .05). Therefore, women who are preparing for pregnancy are recommended to perform regular, moderate-intensity PA.

The association between physical activity and risk of falling in older adults: A systematic review and meta-analysis of prospective cohort studies.

This study investigated the association between physical activity (PA) and risk of falling in older adults and suggests effective PA guidelines based on intensity and amount of PA. We found 10 prospective cohort studies with a total of 58,241 older adult participants and summarized the relative ratio of risk of falling. Older adults who participated in PA had a decreased risk of falling [0.976 (95% CI: 0.957-0.996, p = 0.019)], and inactive older adults had an increased risk of falling [1.082 (95% CI: 1.007-1.163, p = 0.031)]. Older adults who participated in moderate to vigorous intensity PA with low amount of PA had an increased risk of falling [1.217 (95% CI: 1.055-1.403, p<0.007)], when older adults who participated in moderate (3 Metabolic Equivalent: METs or higher) to vigorous intensity PA (6 METs or higher) with very high amount of PA were used as a reference. We recommend participating in PA, including moderate to vigorous intensity PA and a more than medium amount of PA, and avoiding inactivity for older adults to reduce the risk of falling.

Physical activity, sitting time, and the risk of ovarian cancer: A brief research report employing a meta-analysis of existing.

We investigated the associations between physical activity, physical inactivity, and ovarian cancer risk and identified the most effective physical activity intensity and amount to reduce ovarian cancer risk. Thirty-four studies were selected for the present meta-analysis. Physical activity helps decrease ovarian cancer risk. Moderate intensity and low amount of physical activity showed the greatest reduction of ovarian cancer risk and prolonged sitting time had the worst ovarian cancer risk. At least 2 h of moderate physical activity per week and <3 h of sitting time per day provided a preventive effect to ovarian cancer.

DC Magnetron Sputtered IZTO Thin Films for Organic Photovoltaic Application.

IZTO20 (In0.6Zn0.2Sn0.2O1.5) ceramic target was prepared from oxide mixture of In2O3, ZnO, and SnO2 powders. IZTO20 thin films were then deposited onto glass substrate at 400 °C by DC magnetron sputtering. The average optical transmittance determined by ultraviolet-visible spectroscopy was higher than 85% for all films. The minimum resistivity of the annealed IZTO20 thin film was approximately 6.1×10-4 Ω·cm, which tended to increase with decreasing indium content. Substrate heating and annealing were found to be important parameters affecting the electrical and optical properties. An organic photovoltaic (OPV) cell was fabricated using the IZTO20 film deposited under the optimized condition as an anode electrode and the efficiency of up to 80% compared to that of a similar OPV cell using ITO film was observed. Reduction of surface roughness and electrical resistivity through annealing treatment was found to contribute to the improved efficiency of the OPV cell.

Effects of alternate day calorie restriction and exercise on cardio-metabolic risk factors in overweight and obese adults: an exploratory randomized controlled study.

BACKGROUND: It has been recognized that alternate day calorie restriction (ADCR) or exercise has positive effects on cardio-metabolic risk factors. It is unclear whether the combined effect of ADCR and exercise (aerobic + resistance training) influences risk. We investigated effects of an 8-week ADCR and exercise program (aerobic + resistance training) on cardio-metabolic risk factors in overweight and obese adults. METHODS: This study randomized 45 overweight or obese but healthy adults (F = 26, M = 19; aged about 32 to 40 years) into 4 groups: ADCR (n = 13), exercise (n = 10), exercise plus ADCR (n = 12), and control (n = 10) for 8 weeks. Body composition, blood lipids profile, and insulin resistance were measured. The intention to treat (ITT) method was used to analyze all participants that were randomized. RESULTS: A total of 35 participants completed the trial (78%). Body weight, body mass index, waist circumference, fat mass and percent body fat were reduced in the exercise plus ADCR group (- 3.3 ± 2.4 kg, p < 0.01; - 1.3 ± 1.0 kg/m2, p < 0.01; - 4.1 ± 3.9 cm, p < 0.01; - 2.7 ± 2.0 kg, p < 0.01; - 2. 5 ± 2.2%, p < 0.01). Insulin, glucose, homeostasis model assessment insulin resistance and triglyceride (- 2.9 ± 4.1 µIU/ml, p < 0.05; - 10.9 ± 16.9 mg/dl, p < 0.05; - 0.9 ± 1.3, p < 0.05; - 43.8 ± 41.9 mg/dl, p < 0.01) decreased in the exercise plus ADCR group only. CONCLUSIONS: ADCR and exercise both proved to be beneficial, but the combined intervention was most effective at inducing beneficial changes in body weight, body composition, glucose, insulin, insulin resistance and triglyceride in overweight and obese adults.

The Relationship Between Physical Activity and Dementia: A Systematic Review and Meta-Analysis of Prospective Cohort Studies.

Physical activity may decrease the risk of dementia; however, conflicting findings exist. The purpose of the current meta-analysis was to investigate the relationship between physical activity and dementia risk based on physical activity type, amount, and intensity, and to propose an effective minimal physical activity amount for older adults. Forty-four studies were selected for the meta-analysis. Participation in high (a total of >2 hours of activity over the course of three sessions per week) and moderate (a total of >1 hour of activity over the course of two sessions per week) amounts of physical activity showed decreased dementia risks compared to physical inactivity. Vigorous exercise, regular exercise, leisure time physical activities, and gardening showed a positive effect toward lowering dementia risk, but walking was not associated with dementia risk. Physically inactive individuals had a higher dementia risk than those who participated in physical activity. Participation in physical activities produces a favorable effect toward lowering dementia risk. Participating in regular physical activity of >1 hour over the course of two sessions per week and avoiding physical inactivity are recommended for lowering dementia risk.

Cardiopulmonary fitness, adiponectin, chemerin associated fasting insulin level in colorectal cancer patients.

PURPOSE: Since circulating level of insulin is associated with colorectal cancer prognosis, it is important to identify factors contributing to fasting insulin level in colorectal cancer patients. The purpose of the current study is to investigate the association of physical fitness, adiponectin, and chemerin levels with circulating level of insulin in colorectal cancer patients. METHODS: A total of 123 stage II-III colorectal cancer patients who completed standard cancer treatment were recruited. Anthropometric characteristics, fitness measurements, fasting insulin level, homeostasis model assessment of insulin resistance, lipid profiles, and adiponectin and chemerin levels were analyzed. RESULT: Cardiopulmonary fitness level inversely associated with fasting insulin levels (the least fit (1st tertile): 8.11 ± 0.64, moderately fit (2nd tertile): 6.02 ± 0.63, and highly fit (3rd tertile): 5.58 ± 0.66 µU/ml, unfit vs. moderately fit, p < 0.01; unfit vs. highly fit, p < 0.05) after adjustment for gender, age, stage, and BMI. In addition, fasting adiponectin and chemerin levels were associated with fasting insulin levels after adjustment for gender, age, stage, and BMI. In our combined analyses, participants with high adiponectin and low chemerin levels showed significantly lower fasting insulin levels (4.92 ± 0.75 vs. 8.07 ± 0.80 µU/ml, p < 0.01) compared with participants with low adiponectin and high chemerin levels. Multiple linear regression analysis confirmed that cardiopulmonary fitness and adiponectin levels (ß = -0.299, p = 0.002; ß = -0.201, p = 0.033) were independently associated with fasting insulin level. CONCLUSION: Our results suggest that physical fitness and adiponectin and chemerin levels may contribute to circulating levels of insulin. These results suggest that exercise may influence the prognosis of colorectal cancer patients by influencing physical fitness level, circulating levels of adiponectin and chemerin.

Anti-inflammatory effects of Zea mays L. husk extracts.

BACKGROUND: Zea mays L. (Z. mays) has been used for human consumption in the various forms of meal, cooking oil, thickener in sauces and puddings, sweetener in processed food and beverage products, bio-disel. However, especially, in case of husk extract of Z. mays, little is known about its anti-inflammatory effects. Therefore, in this study, the anti-inflammatory effects of Z. mays husk extract (ZMHE) and its mechanisms of action were investigated. METHODS: The husks of Z. Mays were harvested in kangwondo, Korea. To assess the anti-inflammatory activities of ZMHE, we examined effects of ZMHE on nitric oxide (NO) production, and release of soluble intercellular adhesion molecule-1 (sICAM-1) and eotaxin-1. The expression level of inducible nitric oxide synthase (iNOS) gene was also determined by Western blot and luciferase reporter assays. To determine its mechanisms of action, a luciferase reporter assay for nuclear factor kappa B (NF-kB) and activator protein-1 (AP-1) was introduced. RESULTS: ZMHE inhibited lipopolysaccharide (LPS)-induced production of NO in RAW264.7 cells. In addition, expression of iNOS gene was reduced, as confirmed by Western blot and luciferase reporter assays. Effects of ZMHE on the AP-1 and NF-kB promoters were examined to elucidate the mechanism of its anti-inflammatory activity. Activation of AP-1 and NF-kB promoters induced by LPS was significantly reduced by ZMHE treatment. In addition, LPS-induced production of sICAM-1 and IL-4-induced production of eotaxin-1 were all reduced by ZMHE. CONCLUSIONS: Our results indicate that ZMHE has anti-inflammatory effects by downregulating the expression of iNOS gene and its downregulation is mediated by inhibiting NF-kB and AP-1 signaling.

The effect of oncologists' exercise recommendations on the level of exercise and quality of life in survivors of breast and colorectal cancer: A randomized controlled trial.

BACKGROUND: The purpose of the current study was to examine the effect of an oncologist's exercise recommendation with and without an exercise motivation package on the amount of exercise participation and quality of life (QOL) in survivors of breast and colorectal cancer. METHODS: A total of 162 survivors of early-stage breast and colorectal cancer who completed primary and adjuvant treatments were recruited for the current study. Participants were randomly assigned into 1 of 3 groups: 1) control (59 patients); 2) those receiving an oncologist's exercise recommendation (53 patients); and 3) those receiving an oncologist's exercise recommendation with an exercise motivation package (50 patients). At baseline and after 4 weeks, the level of exercise participation and QOL were assessed. RESULTS: Of the 162 participants, 130 (80.2%) completed the trial. Intention-to-treat analysis indicated that participants who received an oncologist's exercise recommendation with an exercise motivation package significantly increased their level of exercise participation in terms of minutes (47.57 added minutes per week; 95% confidence interval, 9.62-85.52 minutes [P =.022] vs control) and in Metabolic Equivalent of Task (MET)-hours per week (4.14 additional MET-hours per week; 95% confidence interval, 1.70-6.58 MET-hours [P =.004] vs control) compared with the control group. Participants who received only their oncologist's exercise recommendation did not increase their exercise participation level. Further analysis demonstrated that role functioning was significantly improved among participants who received an oncologist's exercise recommendation with an exercise motivation package. CONCLUSIONS: Providing an exercise motivation package in addition to the oncologist's exercise recommendation to increase the level of exercise among survivors of breast and colorectal cancer should be considered.

Association between physical fitness, quality of life, and depression in stage II-III colorectal cancer survivors.

PURPOSE: The impact of cancer on quality of life and depression is an important issue. The purpose of this study was to identify the impact of physical fitness on quality of life and depression in stage II-III colorectal cancer survivors. METHODS: Participants in the current study included 122 stage II-III colorectal cancer survivors (57 females; 56.67 ± 9.16 years of age and 55 males; 54.69 ± 9.78 years of age). Fitness was assessed using the 6-min walk test, chair stand test, and push-up test. Quality of life and depression were measured using the Functional Assessment of Cancer Therapy-Colorectal (FACT-C) scale and a 9-item patient health questionnaire interview, respectively. RESULTS: There was a significant association between physical fitness and quality of life and depression in colorectal cancer survivors. The 6-min walk test results were associated with FACT-C total (r = 0.298, p < 0.05), physical well-being (r = 0.230, p < 0.05), functional well-being (r = 0.234, p < 0.05), colorectal cancer concern (r = 0.229, p < 0.05), and depression (r = -0.228, p < 0.05), and the chair stand test results were associated with functional well-being (r = 0.231, p < 0.05), colorectal cancer concern (r = 0.242, p < 0.05), and depression (r = -0.227, p < 0.05) even after controlling for all potentially confounding variables. A multiple regression analysis indicated that the 6-min walk was a significant predictor of health-related quality of life, and participants in the lowest tertile of the 6-min walk test results had lower quality of life and greater depression than those in the highest tertile. CONCLUSION: Improving and maintaining physical fitness are important for quality of life and depression in stage II-III colorectal cancer survivors.

Pregnancy, prenatal care, and delivery of mothers with disabilities in Korea.

The aim of this study was to investigate the whole picture regarding pregnancy, prenatal care, obstetrical complications, and delivery among disabled pregnant women in Korea. Using the data of National Health Insurance Corporation, we extracted the data of women who terminated pregnancy including delivery and abortion from January 1, 2010 to December 31, 2010. Pearson's chi-square test and Student-t test were conducted to examine the difference between disabled women and non-disabled women. Also, to define the factors affecting inadequate prenatal care, logistic regression was performed. The total number of pregnancy were 463,847; disabled women was 2,968 (0.6%) and 460,879 (99.4%) were by non-disabled women. Abortion rates (27.6%), Cesarean section rate (54.5%), and the rate of receiving inadequate prenatal care (17.0%), and the rate of being experienced at least one obstetrical complication (11.3%) among disabled women were higher than those among non-disabled women (P < 0.001). Beneficiaries of Medical Aid (OR, 2.21) (P < 0.001) and severe disabled women (OR, 1.46) (P = 0.002) were more likely to receive inadequate prenatal care. In conclusion, disabled women are more vulnerable in pregnancy, prenatal care and delivery. Therefore, the government and society should pay more attention to disabled pregnant women to ensure they have a safe pregnancy period up until the delivery.

Inhibition of melanogenesis by Gaillardia aristata flower extract.

BACKGROUND: The purpose of the study was to determine the anti-melanogenic and anti-oxidant properties of Gaillardia aristata flower extract (GAE). METHODS: Melanogenesis inhibition by GAE was investigated in cultivated cells and in a human skin model. In cultivated cells, the melanogenesis regulatory effect of GAE was evaluated using melanin content, intracellular tyrosinase activity and anti-oxidant characteristics. In addition, the expression of melanogenesis-related proteins was determined by western blot assay and real-time PCR. RESULTS: GAE reduced the amount of melanin in B16F10 and normal human epidermal melanocyte cells and suppressed intracellular tyrosinase activity in a dose-dependent pattern. Also, GAE significantly decreased the expression of melanogenesis-related proteins (microphthalmia associated transcription factor, tyrosinase, tyrosinase-related protein-1, and dopachrome tautomerase). Real-time PCR results revealed a down-regulation of the mRNAs of these proteins. GAE possessed anti-oxidant characteristics as free radical-scavenging capacity and reducing power. In the three-dimensional human skin model, GAE applied to hyperpigmented skin significantly increased the degree of skin lightening within 2 weeks of treatment. The safety of GAE on human skin was confirmed. CONCLUSIONS: These results indicate the potential of GAE for use in suppressing skin pigmentation. We proposed GAE as a new candidate of anti-melanogenic and antioxidant agents that could be used for cosmetic skin care products.

Anti-glycation activities of phenolic constituents from Silybum marianum (Milk Thistle) flower in vitro and on human explants.

Glycation is an ageing reaction of naturally occurring sugars with dermal proteins, with clinical signs appearing in vivo around age 30, and increasing steadily/regularly with age. The suppleness of the dermis is affected by the formation of bridges between proteins and sugars (Maillard's reaction). The accumulation of advanced glycation end products (AGEs) in skin plays a very important role in skin ageing. Therefore, natural compounds or extracts that possess antiglycation activities may have great anti-ageing potential. In the present study, Silybum marianum flower extract (SMFE) was demonstrated to possess antiglycation activity. We found that SMFE inhibits glycation reaction between BSA and glucose. In addition, antiglycation activity of SMFE was confirmed in a human skin explants model. SMFE reduced Nε-(carboxymethyl) lysine (CML) expression, whereas SMFE stimulated fibrillin-1 expression compared to treatment with methyglyoxal. An active ingredient contributing to the observed activities was identified as silibinin. The antiglycation activity of silibinin was dose-dependent. The beneficial effects of silibinin may be applied to prevention or management of AGE-mediated pathologies, targeting in a pleiotropic and complementary way the biochemical and cellular bases of skin aging.
