Sirtuin 1 (SIRT1) and Peroxisome Proliferator-Activated Receptorγ (PPARγ) are genes that play a role in glucose metabolism. Dysregulation of SIRT 1 and PPARγ is associated with the GDM. Hyperglycemia in GDM induces inflammation and oxidative stress in hepatocytes causing liver damage. Basil extract (Ocimum basilicum L) is one of indonesia medicinal plant has been used as traditional medicice in diabetic disorder. This study aims to investigate the hypoglycemic activity of basil extract by evaluating the expression of SIRT 1 and PPARγ in GDM rats and investigate the potential hepatoprotective effect of basil extract by analyzing the rat’s liver histology. Twenty-four of pregnant rats were divided into four groups; negative control, positive group induced by streptozotocin 40 mg/kg BW intraperitoneally, and two groups of GDM rats treated with 100 mg/kg BW and 200 mg/kg BW of basil extract for 14 days. Blood glucose levels were examined with a blood glucose meter. The expression of SIRT 1 and PPARγ was assessed by the RT-PCR. Histological analysis of the rat`s liver was conducted to determine the percentage of cell damage and tissue edem The data were statistically processed using SPSS. The extract of basil at a dose of 200 mg/kg BW showed an anti-diabetic effect which decreased the glucose level concentration by about two times compared to the untreated rat. It enhanced the expression of SIRT-significantly with a value of p= 0.035 (p <0.05). Basil extract-treated group showed a trend of increasing PPARγ expression, but not statistically significant. In addition, HE staining on the liver showed a tendency to improve in the group given basil extract. This Study concluded that basil extract could increase SIRT 1 and potential to be an anti-hyperglycemic therapy with a hepatoprotective effect.","PeriodicalId":13520,"journal":{"name":"INDONESIAN JOURNAL OF PHARMACY","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89072377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this current study, clindamycin was formulated as the peel-off mask gel, intending to form film, providing the drug release profile in a sustained manner leading to better antimicrobial efficacy and enabling peel-off after use. The peel-off mask gel was designed into many formulations with varying concentrations of film-forming agents. The major film-forming agent was 10 %w/w PVA that was combined with the additional film-forming agents PVP-K30 or SA. Clindamycin 1 %w/w was loaded in the selected formulations F18 (10 %w/w PVA and 20 %w/w PVP-K30) and F21 (10 %w/w PVA and 1.5 %w/w SA). The physical property evaluation of the peel-off mask gel showed that the types and concentrations of film-forming agents influenced the viscosity, spreadability, and film-forming ability. The film’s tensile strength indicating the preference of use was also determined. There was no interaction between the ingredients in the formulation evaluated by FT-IR, XRD, and DSC. The F18 and F21 formulations showed a good to very good spreadability and film-forming ability, a suitable tensile strength with a drying time of approximately 8 min, and pH 4-5. Both formulations provided the highest antimicrobial susceptibility for C. acnes compared to the blank film and the clindamycin solution indicating the potential to be developed as the new market formulation for acne treatment.","PeriodicalId":13520,"journal":{"name":"INDONESIAN JOURNAL OF PHARMACY","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84345919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to perform authentication analysis of OO by FTIR spectroscopy and chemometrics. Principal component analysis was applied in the exploratory data analysis at the initial stage of authentication analysis. Multivariate calibration of principal component regression (PCR) and partial least squares regression (PLSR) were constructed using five types of pre-processed FTIR spectral data.

The 2014-2016 Ebola outbreak in African countries Guinea, Liberia and Sierra Leone has a total of 28,616 cases and 11,310 deaths. People suffering from Ebola disease reported to have symptoms such as fever, body aches, diarrhea and internal and external bleeding. Death from Ebola is mostly caused by multi-organ failure due to internal bleeding and fluid loss. Another Ebola outbreak has spiked this February 2021, suggesting low effectivity of the previous vaccines used. Zaire Ebola virus (EBOV) is known to be the species highly involved on the recent outbreak with a high mortality rate. This study is carried out to design B-cell epitope Ebola vaccine based on the conserved region of Zaire EBOV glycoprotein. Reverse vaccinology and immunoinformatic approaches are used in this study. Samples of Zaire EBOV glycoprotein sequences were retrieved from GenBank, NCBI. The 3D modelling was done by using SWISS-MODEL web server and PyMol software. Phylogenetic tree analysis was also done by using MEGA X. B-cell epitope prediction was done by BepiPred 2.0 and Emini Surface Accessibility using IEDB web server. Epitopes were selected based on its conservancy by comparing the sequences with the MEGA X alignment result. Antigenicity, allergenicity and toxicity properties of the peptides were predicted using VaxiJen 2.0, AllerTOP 2.0 and ToxinPred web servers. In silico cloning was done as the final step using pET-24a(+) expression vector. This study revealed that peptide “LEIKKPD”, “TGFGTNETEYLF”, “PYFGPAA”, “PYFGPA”, and “KLSSTNQL” are the best candidate of B-cell epitope vaccine.

Apart from the benefits, it is undeniable that self-medication can also have several negative impacts. The outcome of self-medication is affected by pharmacist’s clinical ability to provide self-medication services to the patient. This study was aimed to assess the quality of self-medication services in Indonesia using mystery customer approach. A pilot project had been conducted in Bandung, West Java, Indonesia. Mystery customers act as patients who come to the pharmacy seeking self-medication medications for cough/common cold, diarrhea/constipation, pain/fever, and gastritis cases. A total 232 pharmacies were involved in this study and selected through stratified random sampling. The quality of self-medication services was measured by four subdomains: patient assessment, the accuracy of drug selection, the drug information provided to mystery customer, and lifestyle modification counselling. Result showed that patient assessment regarding signs and symptoms only performed by 42,82% pharmacies in Bandung, 14,44% assessed pharmacological and nonpharmacological therapy prior to visit, and only 10,56% assessed patients’ specific medical condition. Although the percentage of patient assessment performed by pharmacies in Bandung were low, interestingly the accuracy of drug selection is relatively high (85,34%). The most prevalent information provided to patient was instruction to consume the medication (59,09%), meanwhile the least delivered information was about side effect (5,17%). Information about lifestyle modification only delivered by 10,34% pharmacies. The quality of self-medication services in Bandung varies depending on the type of pharmacy and service provider. State-owned pharmacy has a higher overall score of self-medication service than private retail pharmacy and private standalone pharmacy (p<0,05). Based on the service provider, pharmacist have a higher score of self-medication service compared to pharmacy technicians and other personnel in pharmacies (p<0,05). This study emphasizes the importance of the pharmacist’s role in self-medication services to ensure rational and safe treatment for patients.","PeriodicalId":13520,"journal":{"name":"INDONESIAN JOURNAL OF PHARMACY","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91260055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study is to determine the anticancer properties of thyme leaves and twigs including profile of bioactive compounds, cytotoxicity, ability of apoptosis induction and caspase-3 activation of different solvent extracts on T47D breast cancer cell line. An experimental study was conducted in eight groups. T47D breast cancer cell line was treated with thyme extracts as treatment group, doxorubicin as positive control, while untreated T47D cells were used as negative control. Thyme was extracted by maceration using 6 different solvents: methanol, ethanol, chloroform, ethyl acetate, dichloromethane, and n-hexane. Bioactive compounds of all extracts were analyzed by GC-MS. Cytotoxicity was investigated through MTT assay on T47D breast cancer cell line. The percentage of apoptosis and caspase-3 were detected by flow cytometry using Annexin V-PI and BD Cytofix/Cytoperm, respectively. Thymol as the main bioactive compound in thyme was found in all extracts. MTT results revealed that six solvents extracts had moderate to weak cytotoxicity with dichloromethane had the lowest IC50 values at 120.23 µg/ml. All thyme extracts promoted apoptosis in T47D cells with apoptosis percentage of methanol, chloroform, ethyl acetate, ethanol, dichlorometane, n-Hexane and doxorubicin were 82.67; 80.98; 73.13; 72.28; 60.62; 27.74 and 98.43%, respectively.

Mixtures of sofosbuvir with hydrophilic sugars at various molar ratios were prepared by ethanol assisted kneading followed by drying. The dry products were then characterized by attenuated total reflectance fourier transform infrared spectroscopy (ATR FTIR), differential scanning calorimetry (DSC), powder X-ray diffraction (XRD) and in vitro dissolution studies. Combined instrumental analysis reflected development of new crystalline species of co-crystal type. This was evidenced by the existence of hydrogen bonding as shown from FTIR spectra, change in the thermal behaviour and appearance of new diffraction peaks in the diffractograms recorded by XRD. The co-crystallization was associated by weakening of intermolecular bonds which resulted in significant increase in the dissolution rate of sofosbuvir.
