Phytochemical screening and assessment of pharmacological properties of Swertia chirayita (Roxb. ex fleming) root methanolic extract

Background and Objective: Various parts of medicinal plants have been used to treat specific disorder from ancient times. Swertia chirayita (Roxb. ex Fleming) is a customary folklore medicine, used in the treatment of liver disorders, fevers, dysentery, diarrhea, stomach problems and other disorders. The present study was carried out in order to assess the antioxidant activity, to evaluate the antifungal properties of the plant’s root and to observe anticancer potential of methanolic extract of Swertia chirayita root. Materials and Methods: Phytochemical analysis and different chemical tests for the screening and identification of bioactive chemical constituents in Swertia chirayita methanolic root extract (SCME) were carried out using the standard procedures. The plants were purchased from local herbal market. In vitro determination of antioxidant properties of SCME were conducted using 1,1-diphenyl-2-picrylhydrazyl (DPPH)radical scavenging activity, H2O2 scavenging activity, Beta-carotene bleaching assay, total antioxidant activity by phosphomolybdenum method, azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical cation scavenging activity and hydroxyl radical scavenging activity. Anticancer activity of SCME was determined according to the protocol of brine shrimp lethality test. Antifungal potential was determined by measuring zone of inhibition on Potato Dextrose Agar (PDA) plates. The different concentrations of SCME used were 3.0, 1.5, 0.75 and 0.37 mg mL–1. The data were evaluated as Mean±Standard Deviations of 5 independent experimental responses. The results were analyzed using t-test for independent samples with SPSS version 16.0. Results: Phytochemical analysis of SCME showed that phlobatannins, tannins, saponins and terpenoids were present. The SCME exhibited strong antioxidant activity in a concentration dependent manner for in all six models. The SCME at dose of 3 mg mL–1 caused 100% death rate of brine shrimp after 72 h. The SCME showed potent activity against Aspergillus flavus (87%) followed by Aspergillus niger (88%) while the highest activity was shown against Aspergillus fumigatus (92%). Conclusion: The SCME exhibited strong antioxidant, antifungal and cytotoxic potential. Purification of different bioactive compounds should be carried out and in vivo studies are required for further verification.Scopu

Teacher’s questioning skills and students’ responses in science subject based on parenting style perspectives

Parenting styles were considered as one of important factors in determining students’ performance in science, especially in elementary school. This study aimed to explain the teacher's questioning skills and student’ responses in science subject based on parenting styles in elementary schools in Batam. This descriptive qualitative research was conducted in the first semester of academic year 2017/2018 and involved four classroom teachers and 109 students. The data collection techniques used were questionnaire and observation. The findings of this study showed that the teacher questioning skills in science subject in elementary schools in Batam were good enough. Meanwhile, the highest frequent parenting style used was authoritarian (94.83%). Yet the style led the students to be less active in learning processes

Synergism between nigella sativa seeds extract and synthetic antibiotics against Mec A gene positive human strains of staphylococcus aureus

Background and Objective: Synergistic combinations of various antimicrobial agents have been introduced as extra successful strategies to combat multidrug resistant (MDR) infections. This study was undertaken to evaluate MDR profiling of Staphylococcus aureus strains isolated from clinical specimens of two public hospitals of twin Pakistani cities as well as to explore in vitro antibacterial potential of Nigella sativa L. (black cumin or black seeds) extract against Mec A gene positive Staphylococcus aureus strains. Materials and Methods: The MDR strains were then screened for positive Mec A gene by PCR and sequencing. A total of 500 bacterial strains were subjected to antimicrobial and Nigella sativa seeds susceptibility and minimal inhibitory concentration assays. The data were evaluated as Mean±Standard deviation of five independent experiments. The results were analyzed using t-test with SPSS version 16.0. Results: Methanolic extracts of Nigella sativa seeds showed maximum activity against Mec A gene positive Staphylococcus aureus alone and in combination with the penicillin antibiotic Augmentin® plus the second-generation Cephamycin, Cephalosporins, Mefoxin® (Cefoxitin). The anti-MRSA activity was reduced when methanolic extracts of Nigella sativa seeds were used in combination with the pain reliever and the fever reducer paracetamol (acetaminophen). Eventually, it has been observed that the anti-staphylococcal activity of Nigella sativa led to changes in bacterial cell morphology indicating that the cell wall of Gram-positive bacteria as likely a target of action. Conclusion: This study provides new insights about synergistic antimicrobial and Nigella sativa crude extract activities against MDR Staphylococcus aureus strains.Scopu

Efektivitas Layanan Informasi Terhadap Pemilihan Karir Dalam Melanjutkan Pendidikan Ke Jenjang (SMA/SMK)

Based on the initial survey, the provision of information services to students as a reference for students who have an understanding of careers that seems still low, is thought to be due to the low desire and willingness of students towards high school and low information about talent and interest in the selection of secondary schools. The purpose of this study is to reveal the effectiveness of information services on career choice in continuing education at the SMA/SMK level. This research was carried out using quantitative methods with the type of pre-experimental research with The One Group Pretest-Posttest. The selection of research subjects used cluster sampling and those who were selected as samples were class IX 1 as the experimental group. The experimental group consisted of 48 students. The instrument used is a questionnaire. Data analysis used One Sample T-Test with SPSS 20 program. The research findings indicate that the factors that influence the effectiveness of information services on career selection are motivation, intelligence, talents and interests of students. This can be seen from the experimental group in the pretest and posttest with a significance of 0.000 or a probability below alpha (0.000 <0.05) with an increase in the score of the research subjects from an average score of 32.9% to 35.78%. Based on the findings above, it can be concluded that this information service is effective in continuing career selection at the SMA/SMK level. This study shows the importance of implementing information services in schools by BK teachers.Berdasarkan survey awal, pemberian layanan informasi terhadap siswa menjadi rujukan siswa memiliki pemahaman tentang karir yang terkesan masih rendah, diperkirakan karena rendahnya keinginan dan kemauan siswa terhadap sekolah lanjutan serta rendahnya informasi tentang bakat minat dalam pemilihan sekolah lanjutan. Tujuan penelitian ini adalah untuk mengungkap efektifitas layanan informasi terhadap pemilihan karir dalam melanjutkan pendidikan kejenjang SMA/SMK. Penelitian ini dilaksanakan menggunakan metode kuantitatif dengan jenis penelitian pre-eksperimen dengan The One Group Pretest-Posttest. Pemilihan subjek penelitian menggunakan cluster sampling dan yang terpilih menjadi sampel adalah kelas IX 1 dijadikan kelompok eksperimen. Kelompok eksperimen berjumlah 48 siswa. Instrumen yang digunakan adalah angket. Data analisis menggunakan Uji-T One Sample dengan program SPSS 20. Temuan penelitian menunjukkan bahwa faktor yang mempengaruhi efektifitas layanan informasi terhadap pemilihan karir yaitu motivasi, intelegensi, bakat dan minat siswa. Hal ini terlihat dari kelompok ekperimen pada pretest dan posttest dengan signifikannya 0.000 atau probabilitas dibawah alpha (0,000 < 0.05) yaitu dengan kenaikan skor pada subjek penelitian dari rata-rata skor 32,9% menjadi 35,78%. Berdasarkan temuan diatas dapat disimpulkan bahwa layanan informasi ini efektif dalam melanjutkan pemilihan karir kejenjang SMA/SMK.
