Cancer is a problem in the health sector because this disease has an increasing incidence of morbidity and mortality. While the treatment still leaves some drug side effects, which cause discomfort for cancers sufferers. The arises because most cancer drugs work non-selectively. Because of some of the problems above, it is necessary to encourage the search for alternative drugs treatment of cancer. Voacanga foetida (Blume) Rolfe (Apocynaceae) is a species of plant from the genus Voacanga known as the tampa badak from West Sumatra. This plant is known to be source of indole alkaloids and also bis-indole alkaloids potential as cancer drugs. Therefore, in this study we are interested to explore the potency of this plant as natural product sources with potential cytotoxic activity. The study was started from the isolation process and continued by characterization of the isolated compounds and then testing their cytotoxic activity T47D breast cancer cell line. The isolation process of alkaloid compounds were performed by acid-base extraction, liquid-liquid fractionation, and followed by separation using column chromatography. Then,the potency of cytotoxic activity of the isolates were screened through Brine Shrimp Lethality Test (BSLT) method and evaluated by MTT assay. The structure of three isolated alkaloids (VFB-DB1.1; VFB-DB2.1; and VFB-DB2.2) were charachterized using spectroscopic analyses, including UV and FT-IR. One isolated compound (VFB-DB1.1) was also characterized using 1H NMR spectroscopy. Based on the similarity of 1H NMR spectra of isolated compound when compared with the literature, compound VFB-DB1.1 was identified as voacangine. Then, the BSLT and MTT assay result showed that VFB-DB1.1 exhibited LC50 value of 15.8 µg/mL againt Artemia salina L.and IC50 value of 8.9 µg/mL against T47D breast cancer cells, respectively.

Silver Nanoparticles (AgNP) are silver particles of no more than 100 nm in size. Silver nanoparticles have antimicrobial characteristics and have been applied to various fields as antibacterial agents. This study aims to formulate and examine the antibacterial activity in preparing silver nanoparticle mouthwash on Staphylococcus aureus. The silver nanoparticles are synthesized using a chemical reduction method, of which the wavelength is then characterized using UV-Vis spectrophotometry, and the PSA instrument is used for particle size. Silver nanoparticles are formulated for a mouthwash with various concentrations such as 0%, 60%, 70%, and 80% consecutively as formula 1, 2, 3, and 4. The observation is then performed on the organoleptic, pH, stability, and bacterial activity of the Staphylococcus aureus using the disk diffusion method. The study results indicate that the preparation of silver nanoparticle mouthwash has a good organoleptic; the average pH of formula 1, 2, 3, and 4 consecutively is 3.40, 3.40, 3.46, and 3.54; however, it is not stable during the storage stage. The result of the antibacterial activity test on Staphylococcus aureus bacteria shows that formula 2 has the most oversized average inhibition zone diameter that is 13.14±0.31 mm compared to formulas 1, 3, and 4, namely 5.20±0.44; 12.40±0.74; and 8.40±0.89 mm. The active formula of mouthwash preparation to inhibit the growth of Staphylococcus aureus bacteria is formula 2.

Indonesia is a country located in the tropics with sun exposure throughout the season. Sun exposure is the best source of vitamin D and there have been no cases of vitamin D intoxication due to excessive sun exposure. Pharmacy students tend to lack knowledge of vitamin D. Changes in lifestyle and modernization lead to high use of sunscreens which can lead to a decrease in the synthesis of vitamin D in the skin. This research was conducted to determine the differences in knowledge and attitudes towards sun exposure using cross sectional method on 100 first semester pharmacy students and 100 final semester students. Test differences in aspects of knowledge and attitudes using odds ratios. The results of the knowledge aspect odds ratio test are 1,000 and the attitude aspect odds ratio test results were 0.583 so that it can be concluded that both knowledge and attitudes towards sun exposure have the same risk tendency for first semester and final semester pharmacy students.

Papaya plants (Carica papaya L.) can be used as traditional medicine. The parts of the plant commonly used as medicine are the seeds and leaves. Assurance of the quality of the extract obtained needs to be carried out by testing specific and non-specific parameters. The aim of the study was to determine the effect of the percentage of ethanol solvent concentration on specific parameters (organoleptic, phytochemical screening, and total phenolic content) and non-specific parameters (moisture content, ash content, and specific gravity) of papaya seed extract (Carica papaya L.). This type of laboratory experimental qualitative research was done to determine the effect of the percentage of ethanol solvent concentration (70% and 95%) on specific and non-specific parameters. Specific and non-specific parameter testing is based on work procedures listed in the Indonesian Herbal Pharmacopoeia. The results of testing the specific parameters on organoleptics showed no difference in the extract obtained, which was viscous and dark brown in color with a characteristic odor. Based on qualitative phytochemical screening, 70% ethanol extract contains alkaloids, flavonoids, tannins, and saponins. However, the 95% ethanol extract was only positive for alkaloids, flavonoids, and tannins. The phenolic content test of 70% ethanol and 95% ethanol extracts was 4.31 ± 0.65 mg GAE/g and 2.69 ± 0.41 mg GAE/g, respectively (Sig 0.022 < 0.05). Extract non-specific parameter test results. The ash content test for 70% and 95% ethanol extracts was 9.5% ± 0.21% w/w and 8.5% ± 0.06% w/w (Sig 0.043 < 0.05). The respective water contents were 8.7 ± 0.11% w/w and 9.7 ± 0.26% w/w (Sig 0.046 < 0.05). The specific gravity of each obtained was 0.88 ± 0.006 % g/ml and 0.75 ± 0.006% g/ml (Sig 0.043 < 0.05). The conclusion of this study is that the concentrations of 70% ethanol and 95% ethanol in papaya seed ethanol extract have an effect on specific parameters, namely the measurement of total phenolic content. While the non-specific parameters affect the water content, total ash content, and specific gravity.

This study aims to assess the efficiency of two agricultural wastes as biosorbents to remove the chemical oxygen demand (COD) from a batik wastewater sample. COD-containing batik wastewater was treated with a combination of biosorbents by eggshells and tea waste activated using H?SO? and then immobilized in calcium alginate through the entrapment technique. The contact time, pH, and biosorbent dose were all investigated to examine the efficiency of biosorbent to remove COD. The independent variables for the optimization process are the contact time (47.13, 50, 60, 70, and 72.87 min), pH of the samples (1.71, 2,3, 4, and 4.28), and the ratio of the number of biosorbent between eggshells: tea waste (2.67:12.33, 3.75:11.25, 7.5:7.5, 11.25:3.75, and 12.33:2.67). The Characterization of the biosorbents was investigated using scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy (FTIR), and energy-dispersive x-ray (EDX) analysis. The results show that eggshells and tea waste immobilized by calcium alginate with a ratio of 2.67 g: 12.33 g, a contact time of 60 min, and a sample pH of 3 are 89% effective in removing the COD in batik wastewater samples.

Diabetes mellitus (DM) is a common metabolic disorder defined as chronic hyperglycemia. In addition to the symptoms associated with hyperglycemia itself such as thirst, polyuria and weight loss, it can also cause acute hyperglycemia emergencies that are potentially life threatening. One of the traditional plants that has potential as an antidiabetic drug is the taro plant (Colocasia esculenta L) because it contains chemical compounds such as alkaloids, flavonoids, saponins, tannins and polyphenols which are known to have antidiabetic effects. This study aims to determine the effectiveness and what dose of Taro Leaf Extract gives the best effect of reducing blood glucose levels in zebrafish. This study used zebrafish (Danio rerio) induced with alloxan and glucose to raise blood glucose levels. The 20 test animals used were divided into 6 groups, namely group 1 without treatment (normal), group 2 control (-) alloxan induction 0.1% + glucose 1%, group 3 control (+) metformin, group 4 taro leaf extract 200 mg, group 5 taro leaf extract 300 mg, group 6 taro leaf extract 400 mg. Then glucose levels were measured using a glucometer. Data analysis was carried out statistical tests. The results showed that a dose of 400 mg/2L had the ability to reduce blood glucose levels that were not significantly different from normal zebrafish glucose levels.

Students undergoing programmes in healthcare will play an important role in the management of antibiotic resistance which is still a global problem. Their knowledge and attitude should be adequately documented. This study is carried out to evaluate the knowledge, attitudes and perceptions of antibiotic use and antibiotic resistance among healthcare students in Central University, Ghana. In this study, 1027 students offering courses in pharmacy, nursing and physician assistantship participated in a survey to evaluate their knowledge, attitudes and perception on antibiotic use and antibiotic resistance. Data obtained was analyzed using STATA statistics DATA analysis software version 12.0. Descriptive statistics and chi-squared test was employed. Students displayed very good knowledge of antibiotic use and antibiotic resistance with students studying physician assistantship and nursing showing greater knowledge. The attitude of the respondents on the use of antibiotics was slightly above average. There was a significant difference (p = 0.029) between students’ programme of study and how they obtained their last course of antibiotics. Students displayed average knowledge on antibiotic use and antibiotic resistance but there is a need for more education to improve their perception and attitudes in order to contribute towards curbing the global problem of antibiotic resistance.
抗生素耐药性仍是一个全球性问题，正在学习医疗保健课程的学生将在抗生素耐药性管理方面发挥重要作用。应充分记录他们的知识和态度。本研究旨在评估加纳中央大学医护专业学生对抗生素使用和抗生素耐药性的知识、态度和看法。在这项研究中，1027 名药学、护理学和助理医师课程的学生参与了一项调查，以评估他们对抗生素使用和抗生素耐药性的知识、态度和看法。获得的数据使用 STATA 统计数据分析软件 12.0 版进行分析。采用了描述性统计和卡方检验。学生们对抗生素的使用和抗生素耐药性有很好的了解，其中学习助理医师和护理专业的学生了解得更多。受访者对使用抗生素的态度略高于平均水平。学生的学习课程与他们如何获得最后一个疗程的抗生素之间存在明显差异（p = 0.029）。学生们对抗生素使用和抗生素耐药性的了解程度一般，但仍有必要开展更多教育，以改善他们的认知和态度，从而为遏制全球抗生素耐药性问题做出贡献。

Coronavirus Diseases 2019, caused by SARS-CoV-2, has been a significant threat to global public health. Unfortunately, effective COVID-19 vaccines and clinically-proven anti-SARS-CoV-2 drugs remain unavailable. This study was carried out aiming to predict the potential effect of mitragynine derivates from the Genus Mitragyna Korth as an inhibitor of Mpro, the main protease of the SARS-CoV-2, by in silico molecular docking study. The crystal structure of the main protease of SARS-CoV-2 as an active site target was obtained from the PDB database (rcsb.org) with PDB ID: 5R84 and 6LU7 with the native ligand of Z31792168 and N3, respectively. The analysis of in silico molecular docking was conducted using Autodock 4.2.6 (100 docking runs). The central grid was placed on HIS41 and CYS145 with a grid box comprised of 40x30x34 (for protein 5R84) and 36x62x40 (for protein 6LU7) points spaced by 0.375 Å was centered on the active site of X=9,812; Y=-0,257; Z=20,849 and X=-9.732; Y=11.403; X=68,483 (XYZ-coordinates), respectively. Our research indicated that mitrjavine and ajmalicine exhibit greater potential inhibition of the active site on the Mpro of SARS-CoV-2, even stronger than native ligands. We believed that these compounds are promising candidates to be examined in further COVID-19 drug discovery studies.
