Ramalina sp. (Ramalinaceae) is a type of lichen known to contain many active secondary metabolite compounds that have the potential to be used as medicine or medicinal raw materials. One of the biological activities possessed by Ramalina sp. lichen is its anticancer activity. This research aims to isolate and identify active secondary metabolite compounds from the methanol extract of the Ramalina sp. lichen and to find out the cytotoxic activity of the isolated compound against MCF7 breast cancer cells. Compound 1 (usnic acid) was successfully isolated from fraction A. The isolation and purification process was carried out starting with a maceration process using acetone solvent, followed by silica gel column chromatography using a gradient solvent system consisting of n-hexane, n-hexane:EtOAc, EtOAc, EtOAc:MeOH, and MeOH with 5% increment of polarity to obtain 17 fractions (F-1 to F-17). From the 17 fractions obtained, fraction 3 (F-3) and fraction 4 (F-4) (eluted with n-hexane:EtOAc 30%), which had the same TLC profile, were combined and named as fraction A. Compound 1 (50 mg) is a yellow needle crystal that was formed in a bottle of fraction A, which was obtained after the process of combining fractions F-3 and F-4 and solvent evaporation process. The crystals were then separated and purified with CHCl3 and MeOH. Compound 1 was then characterized based on spectroscopic data. Various spectroscopic analysis data, including FTIR, 1D- and 2D-NMR, and LC-ESI-MS, show that Compound 1 is a dibenzofuran derivative compound with 18 carbons (3 from carbonyl groups (C=O) and 3 from methyl groups) and 2 hydroxyl (-OH). Cytotoxicity assay showed that at a low concentration of 18.75 ug/mL, Compound 1 caused a 67.06% decrease in MCF7 viability

AbstrakLatar Belakang: Rinitis alergi adalah inflamasi mukosa hidung yang menyerang 30% populasi dunia. Sebuah penelitian menunjukkan bahwa istinsyaq dapat mengurangi derajat sumbatan hidung. Objektif: Penelitian ini bertujuan untuk mengetahui pengaruh melakukan istinsyaq dalam wudhu terhadap derajat sumbatan hidung pada penderita rinitis alergi.Metode: Jenis penelitian ini adalah pre-eksperimental dengan desain one group pretest-posttest. Populasi adalah siswa kelas X dan XI di SMA IT Imam Syafi’I Kota Batam tahun ajaran 2020/2021 yang menderita rinitis alergi dan bersedia untuk berpartisipasi. Skrining rinitis alergi menggunakan kuesioner SFAR dan derajat sumbatan hidung dinilai dengan menggunakan kuesioner NOSE.Hasil: Didapatkan sampel berjumlah 24 siswa. Rata–rata total skor NOSE sebelum edukasi perlakuan istinsyaq adalah 30 ± 18, dan setelah perlakuan istinsyaq di hari ke-14 menurun menjadi 21 ± 18 dan di hari ke-28 menurun kembali menjadi 14 ± 16. Didapatkan penurunan bermakna rata–rata total skor NOSE dengan menggunakan uji Wilcoxon yaitu nilai p value (0,019) < 0,05 di hari ke-14 dan nilai p value (0,002) < 0,05 di hari ke-28 setelah perlakuan istinsyaq.Kesimpulan: Istinsyaq dapat menurunkan rata–rata total skor kuesioner NOSE pada siswa dengan rinitis alergi. Dengan demikian, istinsyaq efektif untuk mengurangi derajat sumbatan hidung pada penderita rinitis alergi.Kata kunci: Istinsyaq, Rinitis Alergi, Score For Allergic Rhinitis, Nasal Obstruction Symptom Evaluation AbstractBackground: Allergic rhinitis is an inflammation of the nasal mucosa that affects 30% of the world's population. A study showed that istinsyaq can reduce the degree of nasal obstruction.Objective: This study aims to determine the effect of performing istinsyaq in wudhu on the degree of nasal obstruction in patients with allergic rhinitis.Methods: This study is a pre-experimental with one group pretest-posttest design. The population is class X and XI students at SMA IT Imam Syafi'I Batam City for the 2020/2021 academic year who suffer from allergic rhinitis and are willing to participate. Allergic rhinitis was screened using the SFAR questionnaire and the degree of nasal obstruction was assessed using the NOSE questionnaire.Results: The sample obtained was 24 students. The average total NOSE score before istinsyaq treatment education was 30 ± 18, and after istinsyaq treatment on the 14th day it decreased to 21 ± 18 and on the 28th day it decreased again to 14 ± 16. There was a significant decrease in the average total NOSE score using the Wilcoxon test, namely the p value (0.019) < 0.05 on the 14th day and p value (0.002) < 0.05 on the 28th day after istinsyaq treatment.Conclusion: In conclusion, istinsyaq can reduce the average total score of the NOSE questionnaire in students with allergic rhinitis. Thus, istinsyaq is effective in reducing the degree of nasal obstruction in patients with allergic rhinitis.Keyword: Istinsyaq, Allergic Rhinitis, Score For Allergic Rhinitis, Nasal Obstruction Symptom Evaluation

Uveitis is an inflammation of the middle layer of the eye, the uvea, which consists of the iris, ciliary body and choroid. Uveitis is one of the causes of ocular morbidity. Common symptoms of uveitis include red eye, eye pain and blurred vision. Patients with uveitis can experience decreased vision to blindness. Research on uveitis in Indonesia is still limited. This study aims to determine the profile of uveitis patients at the ophtalmology departement of RSUP Dr. M. Djamil Padang. This study used a descriptive research design with a retrospective approach which was carried out by observing data from the medical records of uveitis patients at the ophtalmology departement and the medical records section of RSUP DR. M. Djamil Padang period 2020-2022. The study used a total sampling technique. Patient data were analyzed univariately and data presentation in the form of frequency distribution tables. In this study, a total of 50 samples were obtained. The results of this study found out that uveitis patients mostly female (52%) and the majority in the age range 20-60 years (90%). The most common types of uveitis based on anatomical location are panuveitis (56%) and unilateral lateralization (62%). The main etiology of uveitis was infection (42%). Most of the uveitis patients had clinical manifestation of blurred vision (72%) and red eye (72%). More than half uveitis patients visus was <3/60, categorized as blindness (52%).

Ovarian cancer is known as a silent but deadly disease (silent killer) so it is not uncommon for sufferers to end in death. Radiotherapy for ovarian cancer is indicated as adjuvant therapy for advanced stages in an effort to extend survival rate. This review aims to determine the factors that influence survival rates, local control, and toxicity leves in patients receiving radiotherapy for ovarian cancer. This research is a narrative reviw using the PRISMA method. A literature search was conducted in three databases Pubmed, CENTRAL and Science Direct in the 2013-2023 period. The specified keywords are adapted to the terms Medical Subject Headings (MeSH) and research questions using the PEO formula. Articles were selected based on predetermined inclusion and exclusion criteria. There are 9 selected primary articles and included in the narrative reflection. As many as 3 out of 9 studies stated first-line therapy in the form of total debulking surgery of lesions treated before RT as a factor that significantly influenced survival rates, 2 studies stated CA-125 levels before and after RT had a significant effect on survival rates, 2 studies explained that patients with platinum sensitivity and CCC histological subtypes had better survival rates, and 2 other literatures explained that cancer stage at diagnosis, cancer volume, and post-treatment or not after RT also significantly affected survival rates. Ovarian cancer patients who undergo radiotherapy have better survival rate than patients who do not receive radiotherapy with excellent local control and limited radiation related toxicity that is relatively well tolerated by patients

The study on Macarang hypolueca (Reichb.f. & Zoll.), which was collected from secondary forests around Samarinda City, East Kalimantan, involved phytochemical investigations that led to the isolation of a flavone type compound of flavonoid from the ethyl acetate fraction. To separate the compounds, silica gel column chromatography was utilized with a gradient solvent system of n-hexane and ethyl acetate, along with the addition of 5%. Infrared analysis (FTIR), mass spectrum (LC-ESI-MS), and nuclear magnetic resonance (1D- and 2D-NMR) were used to identify and elucidate the structure. Based on spectroscopic data and comparison with appropriate references, the isolated compound was identified as apigenin
