Coenzyme Q10 (CoQ10) is a naturally produced organic molecule which acts as an antioxidant agent, including in skin anti-ageing, and plays a major role in the social determinants of health. However, its level in the body will decrease during ageing. Therefore, an external supplement is required to repair damaged skin, especially the skin dermis layer. This study aims to evaluate the use of a protransfersomal emulgel to improve the skin delivery and stability of CoQ10 which demonstrates low water solubility, poor permeability and instability. CoQ10 was initially dissolved in oleic acid at a weight ratio of 1:56. Protransfersome was then loaded with CoQ10 (Protransf-CoQ10) and prepared using a composition of L-α-Phosphatidylcholine and Tween 80 at a molar ratio of 85:15. The Protransf-CoQ10 was dispersed in an emulgel base consisting of Tween 80 and Span 80 to produce Protransf-CoQ10 emulgel. The in vivo studies of anti-aging activity and irritability were further evaluated by applying daily 200 mg of emulgels twice a day to a 4 cm2 section on the back of a UV-ray aging-induced male Balb/c mouse 20 min before irradiation. The results showed that Protransf-CoQ10 could transform into transfersomal vesicles with particle sizes of approximately 201.5 ± 6.1 nm and a zeta potential of − 11.26 ± 5.14 mV. The dispersion of Protransf-CoQ10 into emulgel base resulted in stable Protransf-CoQ10 Emulgel during 28 days of observation at low temperatures. Moreover, the in vivo study revealed that Protransf-CoQ10 Emulgel successfully increases the collagen density and number of fibroblast cells in UV radiation skin-aged induced-mice which reflects its potential for repairing the skin ageing process. In addition, the 24-h topical application of Protransf-CoQ10 Emulgel showed that no erythema or skin rash was observed during the study. In conclusion, loading CoQ10 into protransfersomal Emulgel successfully enhanced the stability and anti-ageing efficacy enabling its potential use as anti-ageing cosmetics.
Introduction: Congenital cataract is turbidity occurs in eye lens that present at birth or immediately after. We aim to find out visual acuity after congenital surgery between children under 2 years old and 2-17 years old after following up 3, 6, 12 months.Methods: This was a cross-sectional study. Data were gathered from medical record of congenital cataract aged ≤2 years and >2-17 years including age of surgery, frequency of eyes, sex, laterality, and visual acuity of patients with best corrected visual acuity (BCVA). All data analyzed using Mann-Whitney test.Results: 41 children (67 affected eyes) in which 45 eyes that were operated at aged ≤2 years and 22 eyes were operated at aged >2-17 years. There was average difference of visual acuity between age group of ≤2 years and >2-17 years while following-up 3 months (1.60 ± 0.34 logMAR, 1.23 ± 0.67 logMAR, p = 0,003). Whereas in follow up 6 months (1.23 ± 0.47 logMAR, 1.15 ± 0.68 logMAR, p = 0,242) and 12 months (0.94 ± 0.47 logMAR, 0.96 ± 0.44 logMAR, p = 0,840), there were no difference significant average of visual acuity.Conclusion: Visual acuity after following-up 3 and 6 months in age group of >2-17 years were better than age group of ≤2 years, whereas after following-up 12 months in age group ≤2 years, it was obtained that visual acuity was better than age group of >2-17 years.
BACKGROUND: Human immunodeficiency virus (HIV) is an infectious disease that targets the human immune system by attacking cluster of differentiation (CD)4 cells. The use of propolis in HIV patients is expected to be safe and beneficial in terms of increasing endurance and immunity by its role in increasing CD4 level. This study aimed to analyze the influence of propolis supplementation in increasing the CD4 level in anti-retroviral (ARV)-treated HIV patients.METHODS: Double-blind randomized controlled clinical trial was conducted in 50 HIV patients who took regular ARV therapy. The subjects were divided into two groups, one group was treated with ARV and propolis, while another one was given ARV and placebo. The CD4 cell count was measured during pre-treatment, in the 3rd month, in the 6th month after treatment. The level of hemoglobin, leukocyte, and platelets were also measured. The SF-12 questionnaire was used to evaluate quality of life of the subject.RESULTS: Out of 50 subjects, 43 subjects completed the study, which were 19 subjects from the propolis group and 24 subjects from the placebo group. After 3-month of treatment, there was a statistically significant difference in the incrwase of CD 44 level in propolis group, while the increment was not significant in the placebo group. After 6-month treatment, the increase of CD4 level was occurred in both groups, propolis and placebo, however the increment was not statistically significant. The levels of hemoglobin, leukocyte, and platelets were not altered by the treatment and remained normal throughout the study. The quality of life was improved during the study; however, it was also not statistically significant. Mild adverse events occurred in 3 subjects which were relieved after the treatment stopped.CONCLUSION: Based on the result of this study, the administration of propolis on HIV patients receiving ARV bring significant difference in the increase of CD4 in propolis group from baseline to 3 month after the treatment. While in placebo group, this increment was not significant. At the end of study, CD4 count continued to rise up, however the increase was not statistically significant. There are no hemoglobin, leukocyte, platelets, and quality of life abnormalities. Therefore, it is necesary to do further research with a spesific CD4 count. However, it may be beneficial in relieving the clinical symptoms and quality of life of patient living with HIV.KEYWORDS: CD4, ARV, HIV, propolis
Maintaining communication may sometimes be ignored by the speaker. One may have a style of offensive and controversial statements while others speak based on the rules of communication without violating the theory of Grice’s conversational maxims. An example of the former is Trump’s speech about the Orlando Mass Shooting on March 16, 2016. Very often Donald J. Trump’s speeches seem to be offensive and controversial. However, some audiences find them effectively acceptable. To explore Trump’s big phenomenon speech, the authors carry out thorough research by applying the Critical Discourse Analysis which focuses on the text dimension. The results of this research are analyzed by using the qualitative approach. The application of the text dimension theory makes it possible to conclude that in the analysed speech Donald Trump successfully delivered his conservative beliefs and values to the audience by utilizing fear and making use of the media and the tragedy which took place in Orlando in March 2016. His victory in the 2016 presidential elections also points to the effectiveness of the speech. This research contributes to the understanding of critical discourse analysis and the way it functions in the study of various social issues.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
