Abstract

The effectiveness of doxorubicin has decreased due to resistance of cancer cells. One of thenatural ingredients that are proven to reduce the resistance to anticancer is quercetin. Quercetininteracts with doxorubicin via a competition of P-glycoprotein (P-gp) transporter activity. Theaim of this study is to evaluate the interaction of quercetin and doxorubicin as cytotoxicityeffect on MCF-7 cells. Cytotoxicity test was conducted by the MTT method. Mechanism ofinteraction between doxorubicin and quercetin was evaluated with isobologram analysis.Doxorubicin and quercetin inhibited the growth of MCF-7 cells significantly. Doxorubicin andquercetin respectively had IC50 of 21M and 103 M. The interaction of doxorubicin and quercetinwere characterized by the amount of doxorubicin IC50 equivalent and quercetin IC50 equivalentless than 1 and the point-intercept of each IC50 notation equivalent plotted on the graph belowthe additive line. Analysis of isobolograms indicated that the interaction doxorubisn and quercetinin each of the ratios had synergy. Quercetin can be considered to be in a combination wit

Abstract

Introduction: Sepsis is presented as acomplex and multifactorial syndrome where the morbidity and mortality rates still high around the world. Strong evidencewith regard to early predictive factors for mortality and morbidity is rare to be provided. Objective: The aim of this study was to analyse the prominent predictors from the values of laboratory findings among patients with sepsis. Method and Material: The study was aan analytic observational study with a case-control approach. The data were extracted from patients’s medical records between 2014 and 2015. This study involved 50 septic patients admitted to Dr. Soetomo General Hospital, Surabaya, Indonesia. Blood urea nitrogen (BUN), creatinine serum, albumin, leukocytes count, haemoglobin, hematocrite, platelets, sodium, potassium, chloride, prothrombin time (PT), and activated partial thromboplastin time (APTT) were collected from blood samples. Logistic regression was used to estimate sepsis related mortalities frequencies and the relationship between laboratory findings and under 28-days mortality. Result and Discussion: From 50 patients, 22 patients were died (44%). The regression model was intially conducted using all three biomarkers as covariates, then using backward elimination, the covariate with the highest p-value was eliminated. The process was repeated until covariates with statistically significant remained. Multivariate analysis showed that albumin, leukocytes count, and prothrombin time (PT) were the findings associated with high mortality. The independent predictors of mortality identified by further multivariate regression analysis were taken into account as a lower than 3.5 g/dL of albumin, above12.000/µL of leukocytes count, and prolonged more than 14 seconds of prothrombin time; with p value <0,05 respectively (0.029; 0.049; 0.027). Conclusion: Notably, low albumin level, elevated levels of leukocytes, and prolonged prothrombin time were clinically considered as independent predictors of mortality among adult patients with sepsis.

Abstract

Universities participate in realizing Indonesia's vision 2045 “The Indonesians who are excellent, civilized, and mastering science technology, to bring Indonesia as the center of science technology development in the Asia and the world”. It would need intense effort and synergy, considering the science literacy of Indonesian students was ranked the 10th lowest out of 79 countries in 2018. The innovation capacity is ranked 74 out of 141 countries.  Research is an essential activity, encouraging the development of science technology. Research competency should be honed by high school students as part of scientific inquiry. Therefore, this community service was carried out in collaboration with FORISMA FK UNAIR, aimed to increase students’ understanding of the urgency, stages, and procedures of research as well as increase interest in research activities. It was also intended to develop their skills to compile and present research proposals. The partner was Raudlatul Jannah High School Sidoarjo. It was implemented through workshops, coaching, and presentations followed by the teachers and 11th-grade students.  The whole activity successfully improved students' knowledge. Increased knowledge score was obtained in 83% of participants. The pre-test evaluation showed 88% of participants had poor knowledge, whilst post-test evaluations were predominantly good. This community service increased students’ interest in research and changed their perceptions of research’s importance. This improved students' capability to identify research problems, search and compile scientific references as a basis for building hypotheses and conceptual frameworks, and determine research methods. The four groups of students were able to produce research proposals of sufficient quality and were able to present and discuss them in the forum. This community service was perceived to help the school in the implementation of curriculum, especially in science literacy. The school was committed to deepening students' knowledge and skills in the field of scientific research by providing research project modules. This community service is part of the contribution of higher education to the achievement of the vision of Indonesia 2045. This can be a model of scientific inquiry learning in secondary education, thus it is necessary to be implemented in other high schools.

Abstract

Systemic Lupus Erythematous (SLE) is one of the major autoimmune diseases that can cause severe damage to the tissues and organs in the body and lead to high mortality rates. The clinical manifestations are characterized by the production of autoantibody immunoglobulin G (Ig G) that fights component of the nucleus. The present scientific information issues about peculiar property of Tridax procumbens as immunosuppressant by inhibiting enzyme of cyclooxygenase-2 (COX-2) on surface of B cells. This study approved effect of the extract of Tridax procumbens on human lymphocytes cells line with SLE disease. The aim of this study was to approve effect of extract of Tridax procumbens in suppressing Ig G concentration from patient with stable SLE and patient with active SLE in vitro. This study was an in vitro experimental design on lymphocytes cell line that was isolated from whole blood patient with stable SLE and active SLE. Lymphocyte cells from healthy volunteer were also collected as control. American Rheumatism Association Diagnostic was used for inclusion criteria.Tridax procumbens was extracted with maceration method in solution of ethyl acetate. The extract was divided in several doses as immunosuppressant i.e.1000; 250; 62.5; 31.25; 15.13; and 3.91 µg/mL. Supernatant of the cultured cells was collected and examined for measuring Ig G concentration as secretion from activated B cells by ELISA. Ethical clearance had been completed before this study started. The extract of Tridax procumbens significantly suppressed Ig G secretion in patient with stable SLE at dose over 62.5 µg/mL, but Ig G concentration in patient with active SLE was significantly increased when compared with control. Furthermore from the analysis, effect of the Tridax procumbens extract on Ig G concentration followed dose dependent response. In in-vitro study, the extract of Tridax procumbens could significantly suppress Ig G secretion in healthy volunteer and patient with stable SLE. Otherwise, the extract does not suggest for patient with active SLE and it needs caution in use and investigation in-depth. Keywords: SLE, Tridax procumbens, immunoglobulin G ABSTRAK Penyakit Systemic Lupus Erythematous (SLE) merupakan salah satu penyakit autoimun yang sering menyebabkan kerusakan jaringan dan organ sehingga angka kematiannya tinggi. Karakteristik patognomonik penyakit SLE ditandai ada produksi auto antibody immunoglobulin G (Ig G) yang melawan komponen nukleosom tubuh sendiri. Penelitian ilmiah terbaru menunjukkan bahwa ekstrak Tridax procumbens memiliki efek imunosupresan melalui hambatan enzim cyclooxygenase-2 (COX-2) pada permukaan sel B. Pada studi ini menguji efek ekstrak Tridax procumbens pada cells line limfosit dari pasien SLE. Tujuan penelitian ini adalah mengetahui efek ekstrak Tridax procumbens dalam menekan konsentrasi Ig G pasien dengan SLE stabil dan pasien dengan SLE aktif secara in vitro. Penelitian ini merupakan penelitian eksperimen pada cell line limfosit yang diisolasi dari whole blood pasien dengan SLE stabil dan SLE aktif. Kelompok kontrol limfosit diambil dari sukarelawan sehat. Kriteria inklusi pasien yang mengikuti penelitian ini berdasarkan kriteria diagnostik American Rheumatism Association. Tridax procumbens diekstraksi dengan metode maserasi larutan etil asetat. Ekstrak dibagi menjadi beberapa dosis sebagai imunosupresan yaitu 1000; 250; 62,5; 31,25; 15,13; dan 3,91 µg/mL. Supernatan dari sel kultur dikoleksi dan diukur konsentrasi Ig G yang merupakan sekresi sel B dengan menggunakan metode ELISA. Persetujuan etik dilakukan sebelum penelitian dilakukan. Ekstrak Tridax procumbens menekan sekresi Ig G pasien dengan SLE stabil pada dosis diatas 62,5 µg/mL, namun konsentrasi Ig G dari pasien dengan SLE aktif meningkat secara signifikan dibandingkan dengan kontrol. Efek ekstrak Tridax procumbens pada konsentrasi Ig G mengikuti dose dependent response. Pada penelitian ini, ekstrak Tridax procumbens dapat menekan sekresi Ig G dari pasien dengan SLE stabil dan sukarelawan sehat. Pemberian ekstrak Tridax procumbens tidak dianjurkan pada pasien dengan SLE aktif, namun hal ini masih membutuhkan penelitian lebih mendalam. Keywords: SLE, Tridax procumbens, imunoglobulin G
