Review Article: Characteristics of Ovarian Cancer Across Age, Epithelial Histopathology, and Stages
No full textBackground: Ovarian cancer is a disease that has a high mortality rate, it has 185 thousand deaths in 2018. In Indonesia, it is estimated that there are 100 cancer patients per 100 thousand people. Ovarian cancer is a malignancy with no specific symptoms, as a result advanced stage is commonly found at diagnosis and there is no effective screening test to date. However, genetic factors have been found to play a role in this disease. Aims: The aim of this study is to find out the characteristics of ovarian cancer patients. Methods: This research uses a review article research design, with a narrative type. Data collection was taken from a collection of journals sourced from Pubmed and met the inclusion and exclusion criteria set by the author and then summarized. Six journals that included the characteristics of ovarian cancer patients are included in this review article. Results: According to the six journals, the mean age is 54 years old, the most stage found is stage 3, and the most epithelial histopathology found is serous. Conclusion: According to the six journals that were reviewed, the characteristics of ovarian cancer patients based on age, stage, and epithelial histopathology were found to be consistent with the theory that has been established
Insecticidal and Anti-Feedant Activity of Clerodendrum Extracts on Growth and Development of Castor Spiny Caterpillar, Ariadne merione
No full textThe castor spiny caterpillar Ariadne merione (F.) is a major lepidopteran pest affecting castor (Ricinus communis) crops mainly by causing defoliation which in turn reduces the photosynthesis and yield. The conventional pest control methods have been based on chemical control which although has been effective, has its drawbacks of being hazardous to the environment and human health besides leading to resistance by the pests. The present work aims at investigating the possibility of using Clerodendrum inerme, a plant belonging to the Lamiaceae family, as an eco-friendly solution for pest management. Insecticidal and anti-feedant efficacy of C. inerme leaf extracts, which were prepared using solvents hexane, acetone, and petroleum ether, was tested against A. merione larvae using leaf dip bioassay under no-choice situation. The findings showed that the hexane extract had the highest insecticidal (73%) and anti-feedent (97%) action. The petroleum ether extract also showed moderate insecticidal (50%) and anti-feedant activity (48%) but not as potent as the acetone extract having insecticidal and anti-feedant action of 60 and 74 per cent respectively. The results imply that C. inerme extracts, especially the hexane extract, could be used as botanical insecticides in IPM programs as a natural replacement for chemical insecticides
