Cosmetics that are sold in the market are in great demand by many women. The type of cosmetics that is often used is a whitening cream. This cream can provide a whitening effect on facial skin so that it can increase self-confidence. One of the ingredients that have skin whitening properties and is often added to whitening creams is hydroquinone. This material has the effect of inhibiting the formation of melanin so that it can whiten the skin. The use of hydroquinone without medical supervision is not allowed because it can have negative effects such as allergies, skin redness, and a burning feeling. In this paper, we will report the identification results of the hydroquinone content in the whitening cream which is not a distribution license number from the BPOM (Indonesia Food and Drug Supervisory Agency) which is marketed in the Banjarnegara Region area. Samples were taken from the Banjarnegara area and the analysis was carried out at the Pharmacy Laboratory of the Universitas Muhammadiyah Yogyakarta. The analytical method used was the identification of the hydroquinone content carried out by the TLC-densitometry method. Qualitative analysis used TLC, where the stationary phase used was silica GF254 while the mobile phase used was toluene - glacial acetic acid at a ratio of 8: 2. Samples were dotted using a microsyringe of 25 µL after extraction. Furthermore, the spot identification was carried out under 254 nm UV light and then the Rf value was calculated. Quantitative analysis was used. It was carried out by densitometry by looking at the area produced by the spots on TLC. In this analysis, the level calculation was carried out by comparing the area of the hydroquinone sample with the area of the positive control hydroquinone multiplied by the known hydroquinone level in the positive control. The results of the qualitative analysis showed that of the 21 samples, there were 6 samples or 28.57% of the samples containing hydroquinone. Quantitative analysis shows the levels in the six samples containing hydroquinone, namely sample no.11: 7,12%, sample no.12: 3.69%, sample no.15: 0.06%, sample no.16: 11.18%, sample no.18: 4.67%, and sample no.19: 1.07%. Based on the results of the analysis, several preparations contain hydroquinone exceeding a safe level of 5%, so it is necessary to regularly check testing and supervision from the authorized institution so that the circulating whitening cream is safe for use by the public.

Chapter 11 analyzes the costs and benefits of women’s “capability.” On the one hand, women who tried to be “capable” became empowered in concrete ways. They gained self-confidence, feeling psychologically better than they had after experiencing abuse. Some of them experienced important forms of social mobility, acquiring stable jobs and respect from friends and neighbors. Some became members of the public sphere, able to navigate government offices, occupy public space, and lead their own organizational efforts. On the other hand, by trying to be “capable,” women also experienced real uncertainty and risks. They became overworked, overwhelmed, lonely, and physically endangered. Trying to be capable had long-term negative effects on women’s health, mental stability, and, for some, the very desire to survive.

AbstractVisual displays in the news media become critical during escalating events such as the COVID-19 pandemic, as they facilitate the communication of complex information to the public. This article investigates the use of graphs in Korea’s news media during the COVID-19 outbreak. We selected 12 dates that represent turning points in the outbreak of the disease and collected news stories including graphs from seven Korean daily newspapers issued on those dates. First, we analyzed the usage of graphs in COVID-19 news stories. Quantitative analysis of the types and frequency of graphs used in COVID-19 news stories and qualitative analysis of the content of news stories containing graphs were conducted. Second, we identified cases in which readers may be biased by the mathematical misuse of graphs in the news stories covering COVID-19. The implications of these findings for future teaching and learning of graph literacy in school mathematics courses are discussed.

AbstractThere is growing interest among the public and scientific community toward the use of probiotics to potentially restore the composition of the gut microbiome. With the aim of preparing eco-friendly probiotic edible films, we explored the addition of probiotics to the seed mucilage films of quince, flax, and basil. These mucilages are natural and compatible blends of different polysaccharides that have demonstrated medical benefits. All three seed mucilage films exhibited high moisture retention regardless of the presence of probiotics, which is needed to help preserve the moisture/freshness of food. Films from flax and quince mucilage were found to be more thermally stable and mechanically robust with higher elastic moduli and elongation at break than basil mucilage films. These films effectively protected fruits against UV light, maintaining the probiotics viability and inactivation rate during storage. Coated fruits and vegetables retained their freshness longer than uncoated produce, while quince-based probiotic films showed the best mechanical, physical, morphological and bacterial viability. This is the first report of the development, characterization and production of 100% natural mucilage-based probiotic edible coatings with enhanced barrier properties for food preservation applications containing probiotics.

Crataegi folium have been used as medicinal and food materials worldwide due to its pharmacological activities. Although the leaves of Crataegus songorica (CS), Crataegus altaica (CA) and Crataegus kansuensis (CK) have rich resources in Xinjiang, China, they can not provide insights into edible and medicinal aspects. Few reports are available on the qualitative and quantitative analysis of flavonoids compounds of their leaves. Therefore, it is necessary to develop efficient methods to determine qualitative and quantitative flavonoids compounds in leaves of CS, CA and CK. In the study, 28 unique compounds were identified in CS versus CK by qualitative analysis. The validated quantitative method was employed to determine the content of eight flavonoids of the leaves of CS, CA and CK within 6 min. The total content of eight flavonoids was 7.8–15.1 mg/g, 0.1–9.1 mg/g and 4.8–10.7 mg/g in the leaves of CS, CA and CK respectively. Besides, the best harvesting periods of the three species were from 17th to 26th September for CS, from 30th September to 15th October for CA and CK. The validated and time-saving method was successfully implemented for the analysis of the content of eight flavonoids compounds in CS, CA and CK for the first time.

AbstractThe aim of this systematic review was to perform qualitative and quantitative analysis on the toxic effects of chloroquine (CQ) and hydroxychloroquine (HCQ) on skeletal muscles. We designed the study according to PRISMA guidelines. Studies for qualitative and quantitative analyses were selected according to the following inclusion criteria: English language; size of sample (> 5 patients), adult (> age of 18) patients, treated with CQ/HCQ for inflammatory diseases, and presenting and not presenting with toxic effects on skeletal muscles. We collected data published from 1990 to April 2020 using PubMed, Cochrane Library, EMBASE, and SciELO. Risk of bias for observational studies was assessed regarding the ROBIN-I scale. Studies with less than five patients (case reports) were selected for an additional qualitative analysis. We used the software Comprehensive Meta-Analysis at the confidence level of 0.05. We identified 23 studies for qualitative analysis (17 case-reports), and five studies were eligible for quantitative analysis. From case reports, 21 patients presented muscle weakness and confirmatory biopsy for CQ/HCQ induced myopathy. From observational studies, 37 patients out of 1,367 patients from five studies presented muscle weakness related to the use of CQ/HCQ, and 252 patients presented elevated levels of muscle enzymes (aldolase, creatine phosphokinase, and lactate dehydrogenase). Four studies presented data on 34 patients with confirmatory biopsy for drug-induced myopathy. No study presented randomized samples. The chronic use of CQ/HCQ may be a risk for drug-induced myopathy. There is substantiated need for proper randomized trials and controlled prospective studies needed to assess the clinical and subclinical stages of CQ/HCQ -induced muscle myopathy.

Main Components

Light Rail Transit (LRT) is one of the public transports that provides a lot of benefits to the Malaysian. Yet this consumption depends on the diverse tastes of potential ridership which are influenced by various factors. However, it is very challenging to predict significant factors influencing ridership preferences. As such, the identification of these factors is very important in ensuring this transportation service really attract ridership attention. Thus, this paper intends to identify the main factors that influence ridership preference in taking LRT transportation. 28 attributes have been identified in this research which expands from four (4) main components. Data were collected from ridership’s survey, site observations and ridership statistical data. Pearson Chi-square has been employed to justify the significant status and the influence level of each LRT attribute and component factors toward ridership preference. The results show that 23 attributes recorded a significant status (<0.00) in two (2) different directions of correlation. Overall, three (3) component factors namely i) Comfortable Service, ii) Economics and iii) Indoor Environment Conditions, have influenced and contributed to the same effect on ridership considerations, as compared to the negative effects displayed by the Site Design Attributes.

Titania and carbon materials are intensively studied in composite materials including photocatalytic applications. Both positive and negative effects were described in the literature, including charge separation, adsorption enhancement and short-circuiting of the photoelectrons as well. In the present study a more sparsely investigated properties of carbon materials will be highlighted, namely their role as crystallization promoters for titania, during hydrothermal synthesis of the composites. Therefore, carbon nanotubes, carbon coils, activated carbon, graphite and carbon aerogel was used to identify the importance of carbon during the time dependent crystallization of titanium dioxide. The crystal phase composition, morphology, optical properties and photocatalytic activity was followed, and it was found that the anatase and rutile crystallization depended on the used carbon material. The morphology of the particles varied from single anatase sheet-like crystals to hierarchical microball-like structures, while in some cases no specific morphology was observed. Furthermore, it was found that despite the low carbon content (2 wt.%) and microcrystalline structure of TiO2 the composites were proven to be efficient in the degradation of Rhodamine B under UV light irradiation.
