The use of indigenous endophytic bacteria (IEB) isolates as PGPR and resistance induction has been conducted to wilt in tomatoes (Lycopersicum esculentum Mill). This study aimed to obtain the best endophytic bacteria isolates in increasing the resistance of tomato plants to B. tabaci. The research used a completely randomized design (CRD) with ten treatments and three replications. The treatment consisted of eight isolates of IEB, positive controls (without using insecticides), and negative controls (using insecticides). The study was conducted at the Microbiology and Greenhouse Laboratory, Faculty of Agriculture, Universitas Andalas from May to July 2018. The parameters observed were the number of individuals who survived per day and the length of days needed to develop per stage. The results showed that EPL 1.1.4 and KLE 3.3 isolates inhibited egg laying, whereas EI.AB 2.1, EI.AB 1.2, KLE 3.3, and SNE 2.2 inhibited the development of B. tabaci. There was no difference in the length of day between IEB isolates and controls. EI.AB 2.1 showed the most significant adverse effect on the success of B. tabaci life with a value of lx = 0.0 achieved on nymph of instar 3. The result indicated that IEB could be developed in increasing the tomato plants resistance to B. tabaci. [ABSTRACT FROM AUTHOR]

Purpose: Interleukin-18, transforming growth factor-β, and superoxide dismutase are important cytokines and antioxidants in protecting the body from damage caused by radiation exposure through an immune response mechanism. Genetic polymorphisms -607 C/A and -137 G/C are thought to affect the IL-18 cytokine in carrying out its function as a biomarker to indicate adverse conditions due to radiation. The purposes of this study were to investigate the association between 607 C/A and -137 G/C SNPs on the concentrations of IL-18, and to measure TGF-β and SOD activity in radiation workers and control group., Material and Method: We enrolled 40 radiation workers and 40 non-radiation workers as a control group. We determined genotype distribution of -607 C/A and -137 G/C SNPs and their correlation with IL-18 concentration by using PCR-RFLP method. We also measured the IL-18, TGF-β concentration, and SOD activity by using Elisa assay., Results and Conclusion: No relationship was found between -607 C/A and -137 G/C on IL-18 concentrations in all genotype groups, and no significant difference in IL-18 and TGF-β concentrations in the radiation worker and control groups. Significant differences were found only in lower SOD activity in radiation workers compared to controls. The -607 C/A and -137 G/C did not significantly correlate with IL-18 cytokine production in all genotypes. There was no significant difference between IL-18 and TGF-β concentrations in the radiation worker and control groups. However, there was a very significant decrease in the SOD activity of the radiation workers by 3.31 times compared to the controls.

Background: Adolescent pregnancy is prevalent in Asian-African countries. Hence, it is critical to track the progress of research and development trends related to the topic. The study aimed to characterize published articles on teen pregnancy by measuring the authors' country and affiliation, most relevant and cited journals, thematic research, and growth trends., Materials and Methods: Descriptive statistics and retrospective bibliometric analysis were used. Using the Scopus database, we collected published articles from 2010 to 2023. Titles and abstracts were screened. Eligible papers were reviewed based on co-occurrence analysis. Classification and visualization of results were conducted using VOSviewer software version 1.6.17., Results: A total of 369 articles were relevant and included in the review. The countries that produced the most publications were South Africa and the United States. The most relevant affiliation was with the University of Cape Town, the University of the Witwatersrand, and the University of Kwazulu-Natal. The most relevant source journals were PLOS One, Reproductive Health, and BMC Public Health. The most cited sources were Lancet, PLOS One, and AIDS Journal. Four clusters were obtained that reflect the main topics, including human immunodeficiency virus (HIV) infection, child, health services, and pregnancy. The current research terms include HIV infection and maternal health services., Conclusions: This study suggests more research on the term "vertical transmission, breastfeeding, and partner violence" related to teen pregnancy. In addition, this research will inspire researchers and adolescent health policymakers to expand the scope of research to solve teenage pregnancy problems based on interdisciplinary theories and methods., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Journal of Education and Health Promotion.)

Objective: The study aimed to conduct a comparative analysis of the effects of incorporating hydrazinyl coumarin derivative (HCD) in resin-modified (RMGIC) and conventional glass ionomer cement (cGIC) on their release profiles and antibacterial properties., Method: Resin-modified GIC, Fuji II LC (F2) and high-fluoride cGIC, Fuji VII (F7) were used as controls. HCD was synthesized in-house, incorporated into both RMGIC and cGICs at 1 % and 2 % weight percentages (w/w), and chemically analyzed using Fourier transform infrared (FTIR) spectroscopy. Then, the F2 containing HCD (GIC-HCD F2) and F7 containing HCD (GIC-HCD F7) were evaluated for HCD and fluoride release profiles using UV Visible spectrophotometer and pH/ISE benchtop fluoridemeter, respectively. The antibacterial properties were assessed against Streptococcus sanguinis using the agar well diffusion method and measurement of bacterial growth turbidity, followed by the observation of the bacterial morphology using scanning electron microscope. The data were statistically analyzed using one-way ANOVA and Bonferroni post-hoc tests., Results: The FTIR spectra confirmed the presence of HCD in the GIC-HCD matrices. HCD was successfully released from both GIC-HCD F2 and GIC-HCD F7 matrices at both weight percentages. Higher fluoride release and inhibitory zones were observed compared to the control groups, with GIC-HCD F2 having a more significant effect than GIC-HCD F7. Additionally, the incorporation of HCD slowed down the growth of Streptococcus sanguinis and showed remarkable changes in bacterial shape specifically on GIC-HCD F2., Conclusion: The incorporation of HCD into both RMGIC and cGIC improved fluoride release and enhanced the antibacterial activities, with a more significant effect observed in RMGIC compared to cGIC., Competing Interests: The authors have no conflict of interest to declare., (© 2024 The Authors.)
