Clomiphene citrate vs Letrozole as first line ovulation induction drug in infertile PCOS women
Authors: MS Elmahaishi
Published: August 2024

Background: Polycystic ovary syndrome (PCOS) is the commonest endocrinopathy resulting in anovulatory infertility in young women as in recent years have seen a significant rise in women presenting with PCOS . Despite wide acceptance of clomiphene citrate (CC) as the first-line drug for ovulation induction in women with polycystic ovaries (PCOS), a significant proportion of women do not respond to this treatment. In addition, CC use is known to have several disadvantages, including a discrepancy between ovulation and conception rates. Recent studies have suggested that letrozole, an aromatase inhibitor, can be used for ovulation induction and is associated with higher pregnancy rates and less complications than CC treatment in women with PCOs.

The Influence of Financial Inclusion on Stock Market Participation in Nepal: Exploring the Mediating Effect of Financial Knowledge
Authors: Shrestha Purna Man , Rana Mahesh
Published: August 2024

This paper focuses on financial inclusion (FI), a fast-embracing topic with potential drivers of economic growth and the improvement of individual financial well-being. This study contributes to the existing literature by analysing how financial inclusion influences stock market participation (SMP) in Nepal, explicitly emphasising the intermediary role of economic knowledge. The study employed a causal-comparative research design, and the data were collected from 403 individual investors actively participating in the Nepal Stock Exchange (NEPSE) trading. The statistical tools used to meet the objectives of this research are descriptive statistics, factor analysis, and structure equation modelling. The study results show that FI and knowledge influence individual investor participation in the stock market. The result also indicates that FI is positively related to stock market activity, while it is essential to enhance citizens' FK significantly. Further, mediation analysis shows that FK partially mediates the relationship between FI and SMP. This suggests its pivotal role in narrowing the gap between access to financial services and actual investment behaviour. These findings underscore the critical role of FI in creating an inclusive and participatory financial ecosystem within Nepal. Longitudinal data in future research can capture the evolving dynamics of FI and its long-term impact on SMP.

Published: August 2024

Existem vários medicamentos à base de Cannabis registrados no Brasil e em vários países. Contudo, o preço elevado desses medicamentos e o gasto com a importação penaliza a população. Por conta disso, várias pessoas cultivam a Cannabis em seus domicílios, utilizando habeas corpus preventivos, para produzirem extratos artesanais. O objetivo deste trabalho é identificar os dois canabinoides majoritários tetrahidrocanabinol (THC) e o canabidiol (CBD) em óleos caseiros artesanais por cromatografia gasosa acoplada a detector de espectrometria de massas (GC-MS). Os óleos foram diluídos em clorofórmio na proporção de 1:10 e foi adicionada cafeína como padrão interno. As análises foram realizadas no laboratório da Polícia Federal de Recife. Acerca dos perfis de canabinóides em 57,1% (n=16) dos extratos caseiros prevaleceram com a presença de THC, 32,1% (n=9) CBD e 10,8% (n=3) THC e CBD. As concentrações apresentaram grande variabilidade, de 0,24 a 5,38%. Análises se mostraram rápidas, simples, de baixo custo e com boa sensibilidade. Existe uma grande variabilidade nas concentrações de THC e CBD, provavelmente devido a diferentes métodos de extração, variedades da planta e condições de plantio, havendo necessidade de padronização desses parâmetros.

Published: August 2024

Os restaurantes japoneses têm se tornado cada vez mais populares no Brasil, especialmente o consumo de peixe cru, como o sashimi de salmão. No entanto, a falta de boas práticas de fabricação pode aumentar o risco de desenvolvimento de microrganismos patogênicos e doenças alimentares. Este estudo avaliou a qualidade microbiológica do sashimi em cinco restaurantes de Santa Fé do Sul (SP) e região (R1, R2, R3, R4 e R5). Foram realizadas análises microbiológicas qualitativas e quantitativas. A análise qualitativa utilizou o método swab em meio de cultura TSA (trypticase soy agar), incubando-se as amostras a 37 ºC por 48 horas, seguidas pela coloração de Gram. Já a análise quantitativa verificou a contagem de coliformes termotolerantes a 45 ºC e a presença de Salmonella spp. Os resultados revelaram contaminação por bactérias dos gêneros Coccus e Bacillus em todos os restaurantes. Na análise quantitativa, todas as amostras apresentaram coliformes termotolerantes a 45 °C. Foram encontrados também Escherichia coli no R1, bolores e leveduras nos R2 e R3, e Vibrio e Salmonella spp. no R5. A presença e a quantidade desses microrganismos patogênicos, acima dos limites estabelecidos pela Instrução Normativa 60/2019 da ANVISA, indicam condições higiênico-sanitárias insatisfatórias nos restaurantes. O estudo destaca a necessidade urgente de implantação e manutenção das Boas Práticas de Fabricação em Unidades de Alimentação e Nutrição (UANs).

Published: August 2024

Plantago tomentosa Lam. (Plantaginaceae) is an herbaceous plant native to Brazil. It is widely used in folk medicine. The species has potential for use in the pharmaceutical and food industry due to its possible bioactive properties and the presence of mucilage in the seeds. The objective of this work was to investigate the influence of different concentrations of Murashige-Skoog (MS) medium on germination and seedling formation in vitro of P. tomentosa. The seeds were collected in Lajeado, disinfected, and inoculated in bottles with MS medium added to 7 g L-1 of agar and 30 g L-1 of sucrose, in four treatments: 25%, 50%, 75%, and 100% of the medium concentration. The experimental design was completely randomized, consisting of 17 replications of ten seeds for each treatment. The evaluation of germination and formed seeds was carried out every two days to determine the variables of germination percentage (GP), mean germination time (MGT), germination speed index (GSI), seedling formation percentage (SFP), mean seedling formation time (MSFT) and seedling formation speed index (SFSI). No significant difference was found between treatments for all the assessed variables. It is concluded that the use of a concentration of 25% of the MS medium is viable, as it promoted a high percentage of germination and seedling formation and in a time interval similar to that of the other concentrations, with the advantage of using fewer reagents.

Authors: Shin Hyewon , Kim Haeni , Hong Minho , Lee Juhyun
Published: August 2024

This study aims to evaluate the color stability and surface roughness of the single-shade composite resin after finishing and polishing for primary molars. A single-shade composite resin (OM, OMNICHROMA) and two multi-shade composite resins (FT, FiltekTM Z350XT; ES, ESTELITE® SIGMA QUICK) were included. The specimens were divided into three subgroups using different polishing methods: control, Sof-Lex XT, and Sof-Lex Diamond. For color stability tests, cavities were prepared on extracted primary second molars and restored with experimental composite resins. Each specimen was immersed in the coffee solution for 48 hours. The color difference of each specimen was calculated. For surface roughness tests, cylindrical specimens were crafted with experimental composite resins. Surface roughness was analyzed using an atomic force microscope and a scanning electron microscope. In the color stability tests, FT demonstrated a significantly lower ΔEab than ES among the control groups, but no significant differences were observed between the ΔEab values of OM and FT or OM and ES. Additionally, no significant differences were found between the Sof-Lex XT and Sof-Lex Diamond subgroups in the three composite groups. Moreover, no significant differences in the surface roughness were found between the three composite groups, regardless of the polishing methods. The single-shade composite resin demonstrated comparable color stability and surface roughness to that of the multi-shade composite resins regardless of the polishing methods used in restoring primary molars.

This study aimed to identify the clinical characteristics of molar root-incisor malformation (MRIM) and provide clinical considerations for treatments. Panoramic radiographs and electronic medical records of 64 patients with MRIM were retrospectively reviewed. Age, gender, follow-up period, medical history, complications, distribution of MRIM teeth, treatment, and prognosis were analyzed. Females were affected 1.56 times more than males, and the average age was 8.2 years. Dental complications, including periapical lesions, abscesses, and alveolar bone loss, were observed in 71.9%, and eruption disturbance of adjacent teeth was noticed in 37.5%. Most patients had medical histories in the first year of life. The most prevalent history was prematurity or low birthweight, followed by neurological conditions, surgeries, medications, and infections. All patients had MRIM on permanent first molars. The primary second molars were the second most frequently involved, followed by maxillary permanent central incisors and primary first molars. The prevalence was low on permanent lateral incisors and canines. Extraction was the most prevalent treatment done on MRIM-affected teeth, and most extraction sockets were managed by the eruption of permanent second molars. Few cases received endodontic treatment but with low success rates. Early detection of MRIM and prompt, appropriate treatment are important to avoid unnecessary discomfort from complications.

Research using random forest hyperparameter optimization in the case of acute coronary syndrome allows us to obtain a more optimal prediction model, but we can find a gap assumption where the learning carried out by the model still shows symptoms of over-fitting, characterized by a fairly large gap between the training and cross-training processes. validation in the model evaluation process. The research that will be carried out will provide a more optimal prediction model and will not produce symptoms of overfitting of the model using optimization techniques for the hyperparameters in the random forest algorithm. After carrying out various scenarios and testing accuracy, precision scores and various combinations of hyperparameters in the random forest algorithm, it was concluded that the model with the best optimization had a split ratio of 90:10 with an accuracy level of 84.44%, a precision score of 85, 29% and an MSE score of 0.1556 with the results of a combination of random forest optimization hyperparameters using gridCV. The optimization model using random grid cross validation that was built succeeded in reducing the level of over-fitting in the data, decreasing the MSE (mean squared error) from 0.17 and 0.24 to 0.15 for each model.
