"Inflamasi memiliki peran penting dalam perkembangan berbagai kondisi patologis, yang dimediasi oleh aktivasi berbagai jalur pensinyalan, termasuk jalur IKK-NF-κB. Silybin, senyawa flavonolignan yang ditemukan dalam Milk Tistle (Silybum marianum L) telah digunakan secara tradisional untuk mengobati penyakit hati dan telah dilaporkan memiliki aktivitas anti-inflamasi, antifibrotik, dan imunomodulator. Namun, mekanisme molekuler silybin sebagai agen antiinflamasi potensial terhadap jalur pensinyalan IKKNF- κB masih belum jelas. Penelitian ini menggunakan simulasi penambatan molekuler menggunakan Autodock 4.0 untuk menyelidiki interaksi antara Silybin dan NF-κB. Hasil penelitian menunjukkan bahwa silybin menunjukkan inhibisi kompetitif-ATP dan memiliki afinitas pengikatan yang tinggi untuk makromolekul IkB kinase beta (IKKβ) dan NIK (NF-kB-inducing kinase), dengan energi pengikatan -9,73 kkal/mol pada rantai A dan -9,84 kkal/mol pada rantai B IkB kinase beta (IKKβ) serta -9,34 kkal/mol pada makromolekul NIK (NF-kB-inducing kinase). Konstanta Inhibisi (Ki) ditemukan masingmasing 74,14 nM pada rantai A dan 61,12 nM pada rantai B IkB kinase beta (IKKβ) serta 141,81 nM mol pada NIK (NF-kB-inducing kinase). Temuan ini menunjukkan bahwa silybin memiliki potensi untuk menghambat jalur pensinyalan IKK-NF-κB, sehingga memberikan efek anti-inflamasi. Selain itu, silybin menunjukkan afinitas pengikatan yang lebih tinggi jalur persinyalan kanonikal dibanding jalur perisnyalan alternatif. Studi ini memberikan wawasan tentang mekanisme molekuler silybin sebagai agen antiinflamasi potensial dan aplikasi terapeutiknya dalam terapi penyakit yang berhubungan dengan Inflamasi.

Inflammation has a crucial role in the progression of various pathological conditions, mediated by the activation of multiple signaling pathways, including the IKK-NF-κB pathway. Silybin, a flavonolignan compound extracted from Milk thistle (Silybum marianum L.) has been traditionally used to treat liver disorders and exhibits pharmacological properties, including anti-inflammatory, antifibrotic, and immunomodulatory activities. However, the molecular mechanisms underlying Silybin's anti-inflammatory potential, particularly its interaction with the IKK-NF-κB signaling pathway, remain unclear. This study employed molecular docking simulations using Autodock 4.0 to investigate the interaction between Silybin and NF-κB. The results showed that silybin exhibited competitive-ATP inhibition and high binding affinity for IkB kinase beta (IKKβ) and NIK (NF-kB-inducing kinase) macormolecule, with binding energies of -9.73 kcal/mol on the A chain and -9.84 kcal/mol on the B chain of IkB kinase beta (IKKβ) and -9.34 kcal/mol on NIK (NF-kB-inducing kinase). Inhibition constants (Ki) were found to be 74.14 nM on chain A and 61.12 nM on chain B of IkB kinase beta (IKKβ) and 141.81 nM mol on NIK (NF-kB-inducing kinase), respectively. Notably, silybin displays higher binding affinity for the canonical pathway compared to the alternative pathway. These findings suggest that silybin has the potential to inhibit IKKNF- κB signaling, leading to anti-inflammatory effects. This study provides valuable insights into the molecular mechanism of silybin as a potential anti-inflammatory agent and its therapeutic applications in inflammation-related diseases."

"Sepsis merupakan respons inflamasi sistemik pejamu terhadap infeksi. Respons inflamasi dimediasi oleh sitokin yang akan dilepaskan ke sirkulasi. Pelepasan sitokin akan menyebabkan terjadinya aktivasi koagulasi melalui peningkatan ekspresi tissue factor (TF) dan penurunan inhibitor alamiah, serta penurunan fibrinolisis. Tissue factor (TF) merupakan inisiator penting pada proses koagulasi, yang diekspresikan di sirkulasi darah oleh monosit aktif. Aktivasi TF selain menyebabkan aktivasi koagulasi juga dapat memodulasi inflamasi pada pasien sepsis berat. Heparin selain sebagai antikoagulan, berperan sebagai antiinflamasi. Berdasarkan fungsi heparin sebagai antiinflamasi dan peranan TF dalam inflamasi, ingin diteliti apakah pemberian heparin dapat menurunkan aktivitas TF yang diekspresikan monosit pada keadaan inflamasi.
Penelitian ini bertujuan untuk mengetahui perbedaan aktivitas TF monosit pada orang sehat dan pasien sepsis berat dan perbedaan aktivitas TF monosit pada pasien sepsis berat dengan pemberian heparin in vitro dibandingkan dengan kelompok tanpa heparin.
Penelitian ini merupakan penelitian eksperimental dengan menggunakan sampel 10 orang pasien sepsis berat dan 5 orang sehat. Darah sitrat dipisahkan sel mononuklear darah tepi (peripheral blood mononuclear cell/ PBMC) dengan teknik Ficoll-Paque, dan isolat monosit diperoleh dari PBMC menggunakan Monoclonal Antibody Cell Sorter (MACS) microbeads. Isolat monosit dipisahkan menjadi tiga kelompok, yaitu kelompok pertama langsung diperiksa aktivitas TF, kelompok kedua diinkubasi 6 jam dengan heparin 0.1 IU, dan kelompok ketiga diinkubasi 6 jam tanpa heparin. Isolat monosit kemudian dibuat lisat sel dan supernatan diukur aktivitas TF (Actichrome TF).
Hasil penelitian menunjukkan terdapat perbedaan bermakna aktivitas TF monosit pada pasien sepsis berat dibandingkan orang sehat (p=0.002). Aktivitas TF monosit pada pasien sepsis berat yang mendapat heparin 0.1 IU berbeda bermakna setelah jam ke-6 dibandingkan tanpa heparin (p=0.003).

Sepsis is a host systemic inflammatory response to infection. Inflammatory response is mediated by cytokines released into circulation. Cytokine leads to coagulation activation by elevating tissue factor (TF) expression, reducing natural inhibitors, and impeding fibrinolysis. TF is an important initiator in coagulation process, expressed in blood circulation by active monocytes. TF activates coagulation and modulates inflammation in severe septic patients. Heparin acts as anticoagulant and antiinflammatory agent. Based on heparin as antiinflammatory agent and role of TF in inflammation, heparin can decrease TF activity expressed on monocyte in inflammation.
This study aims to find the difference between monocyte TF activities in healthy people and severe septic patients, and also between monocyte TF activities in severe septic patients receiving heparin in vitro and without heparin group.
This study is a laboratory experiment using 10 samples from severe septic patients and 5 healthy samples. Peripheral blood mononuclear cells (PBMCs) are separated from citrate blood using Ficoll-Paque technique. Monocyte isolation is performed using Monoclonal Antibody Cell Sorter (MACS) microbeads. Monocyte isolate is divided into three groups, first group is measured for TF activity directly, second group is incubated 6 hours with heparin 0.1 IU, and third group is incubated without heparin. Cell lysate is processed from monocyte isolate and supernatant is measured for activity TF (Actichrome TF).
The result shows a significant difference between monocyte TF activity in severe septic patients compared to healthy people (p = 0.002). Monocyte TF activity in severe septic patients with heparin 0.1 IU/mL in the 6th hour is also significantly different than without heparin group (p = 0.003).

"Inflamasi kronik adalah proses yang penting dalam patofisiologi adenokarsinoma duktal pankreas (PDAC). Beberapa studi telah meneliti potensi enzim siklooksigenase-2 (COX-2) sebagai faktor prognostik PDAC, dengan hasil yang kontradiktif. Nuclear factor kappa−B (NF−?B), specificity protein 1 (Sp1), dan c−Jun adalah faktor transkripsi gen COX2. Penelitian ini adalah studi observasional eksploratori yang bertujuan untuk mengidentifikasi asosiasi ekspresi protein NF−?B (RelA/ p65), COX−2, Sp1, dan c−Jun dengan kesintasan pasien PDAC. Ekspresi protein tersebut dinilai di jaringan pasien PDAC menggunakan metode imunohistokimia. Diidentifikasi ekspresi keempat protein tersebut dengan overall survival (OS) dan karakteristik klinikopatologis pasien PDAC. Sebanyak 53 jaringan PDAC dari biopsi atau reseksi kanker diikutkan dalam penelitian. Hasilnya terdapat korelasi antara keempat protein di jaringan kanker. Ekspresi NF−?B sitoplasmik (aHR = 0.31; 95% CI 0.11–0.90; p = 0.032) atau nuklear (aHR = 0.22; 95% CI 0.07–0.66; p = 0.007) berhubungan secara independen dengan prognosis pasien yang lebih baik. Protein lainnya tidak berhubungan dengan kesintasan pasien. Hal ini menunjukkan bahwa peran inflamasi di PDAC lebih kompleks dari yang diperkirakan sebelumnya.

Chronic inflammation is a crucial driver of carcinogenesis in pancreatic ductal adenocarcinoma (PDAC). Several studies have investigated the prognostic significance of cyclooxygenase−2 (COX−2) expression in PDAC patients, obtaining conflicting results. Nuclear factor kappa−B (NF−?B), specificity protein 1 (Sp1), and c−Jun are known as the transcription factors of the COX2 gene. This exploratory observational study investigated the association of the NF−?B, COX−2, Sp1, and c−Jun expressions with patient survival in PDAC. We used the immunohistochemical method to detect the PDAC tissue expressions of NF−?B (RelA/p65), COX−2, Sp1, and c−Jun. The expressions of these proteins were correlated with the overall survival (OS) and other clinicopathological characteristics of PDAC patients. We obtained 53 PDAC specimens from resections and biopsies. There were significant correlations between the four proteins’ expressions in the PDAC tissues. The expression of the cytoplasmic (aHR = 0.31; 95% CI 0.11–0.90; p = 0.032) or nuclear NF−?B (aHR = 0.22; 95% CI 0.07–0.66; p = 0.007) was independently associated with a better prognosis in the PDAC patients. COX−2, Sp1, and c−Jun showed no significant association with a prognosis in the PDAC patients. The PDAC patients who expressed NF−?B had a better prognosis than the other patients, which suggests that the role of inflammation in PDAC is more complex than previously thought."

"Latar Belakang : Kanker payudara merupakan salah satu penyebab kematian tertinggi akibat kanker pada wanita di Indonesia. Hal ini diantaranya disebabkan karena adanya resistensi terhadap terapi berlandaskan ROS seperti pada radioterapi maupun kemoterapi. Sel punca kanker payudara (cancer stem cells, CSCs) memiliki peran pada mekanisme resistensi ini. Penelitian terhadulu menunjukkan kemampuan CSCs untuk bertahan terhadap kondisi stress oksidatif pada pemberian rotenon. Karena itu, dalam penelitian ini dilakukan analisis terhadap faktor transkripsi NF-kB pada sel kanker payudara baik CSC maupun non CSC, terkait peran NF-kB dalam mempertahankan viabilitas sel kanker pada kondisi stress oksidatif.
Metode: Penelitian dilakukan pada sel punca kanker payudara manusia (CD24-/CD44+) maupun non sel punca (CD24-/CD44-) yang diberi H2O2 dengan konsentrasi 1.1µM, 11µM, dan 110µM dengan kontrol sel yang tidak diberi H2O2. Penilaian dilakukan terhadap parameter ekspresi mRNA NF-kB, dan viabilitas sel. Uji statistik dilakukan menggunakan IBM-SPSS dengan nilai α < 0.05.
Hasil: Pemberian H2O2 pada konsentrasi 11µM menunjukkan peningkatan yang signifikan pada ekspresi mRNA NFkB CSCs dibanding non CSCs (p<0.05). Sedangkan untuk hasil uji viabilitas pada seluruh konsentrasi H2O2 nampak bahwa CSCs mampu mempertahankan viabilitasnya dibandingkan dengan non CSCs yang mengalami penurunan viabilitas (p<0.05)..
Kesimpulan: Kondisi stres oksidatif akibat pemberiaan H2O2 dapat meningkatkan ekspresi mRNA NF-kB pada CSCs sehingga viabilitasnya tetap dapat dipertahankan.

Introduction: Breast cancer is one of the highest causes of death from cancer in women in Indonesia. This is partly due to the resistance to ROS-based therapies such as radiotherapy and chemotherapy. Breast cancer stem cells (cancer stem cells, CSCs) have a role in this resistance mechanism. Previous studies demonstrated the ability of CSC to survive oxidative stress conditions due to rotenone administration. Therefore, in this study an analysis was carried out on the transcription factor NF-kB in breast cancer cells, both CSCs and Non CSCs, related to the role of NF-kB in maintaining the survival of cancer cells under conditions of oxidative stress.
Methods: The study was conducted on human breast cancer stem cells (CD24-/CD44+) and non stem cells (CD24-/CD44-) which were given H2O2 at concentrations of 1.1µM, 11µM, and 110µM with control cells not given H2O2. Assessment was carried out on the parameters of NF-kB mRNA expression, and cell viability. Statistical tests were performed using IBM-SPSS with a value of α < 0.05.
Results: Administration of H2O2 at a concentration of 11µM showed a significant increase in the expression of NFk-B CSCs mRNA compared to non CSCs (p<0.05). As for the viability test results at all concentrations of H2O2 it appears that CSCs was able to maintain its viability compared to non CSCs which experienced a decrease in viability (p<0.05).
Conclusion: Conditions of oxidative stress due to administration of H2O2 can increase the expression of NF-kB mRNA in CSCs so that its viability can be maintained.
In this study, conditions of oxidative stress due to administration of H2O2 led to an increase in the expression of NF-kB mRNA in CSCs so that cell viability could be maintained.

"Kurangnya penelitian mengenai transisi pada pola asupan dan marker inflamasi usus pada anak gemuk. Studi ini bertujuan untuk melihat hubungan anatara pola asupan dan fecal calprotectin pada anak prasekolah.Studi potong lintang ini dilakukan pada 101 anak dengan BMI Z score > 1 SD dengan median 2.26 (1.61, 3.43) SD serta menggunakan semiquantitative food frequency questionnaires yang telah divalidasi dimana, pola asupan diperoleh dengan menggunakan principal component analysis. Hasil studi menunjukkan 66% anak mempunyai kadar fecal calprotectin > 50 µg/g dan berhubungan dengan BMI Z score (p=0.05, r=1.89). Pola asupan (healthy pattern p=0.132, western pattern p=0.555, staple pattern p=0.541 and milk pattern p=0.534) ditemukan tidak berhubungan dengan inflamasi saluran cerna. Penelitian lebih lanjut dibutuhkan untuk mengkonfirmasi hasil studi ini dengan menggunakan pendekatan lain dan kombinasi antar marker inflamasi usus.

Lack of study confirmed the relationship between transition of diets and gut inflammation marker in obese children. Our study aimed to investigate the association between dietary pattern and fecal calprotectin level in preschool children. A cross sectional study was conducted in 101 children with body mass index (BMI) Z-score > 1 SD and median 2.26 (1.61, 3.43) SD using validated semi quantitative food frequency questionnaires whereas dietary patterns were revealed by principal component analysis. We found 66% children had fecal calprotectin levels > 50 µg/g. The fecal calprotectin level correlated with BMI Z score (p=0.05, r=1.89). Major dietary patterns were revealed: healthy pattern (p=0.132), western pattern (p=0.555), staple pattern (p=0.541) and milk pattern (p=0.534) and multivariate analysis showed no significant association with fecal calprotectin even after full adjustment for age, sex, sedentary physical activity, BMI Z score, fat intake and total fibre intake. Our findings acknowledged the insignificant association diet with gut inflammation marker had been observed due the baseline characteristic BMIZ score of the children more contribute to the elevated of fecal calprotectin level. Further investigations are warranted with a specific inflammatory food approach using a combination of marker gut inflammation."

"Latar belakang: Meningioma memiliki kemampuan menyebabkan inflamasi seperti tumor lainnya. Adapun posisi meningioma yang diluar sawar darah otak menyebabkan gambaran inflamasi pada lingkungan mikro tumor lebih tergambarkan pada darah tepi dibandingkan tumor yang berada di intraparenkim. Hal ini dibuktikan dengan tinkat c-reactive protein yang lebih tinggi pada meningioma dibandingkan tumor intraaksial walaupun derajat meningioma lebih rendah. Oleh karena itu dilakukan penelitian yang bertujuan untuk mengetahui hubungan aktivasi inflamasi perifer berdasarkan NLR dan MLR dengan gejala klinis, edema peritumoral, dan rekurensi meningioma.
Metode penelitian: Penelitian ini dilakukan dengan studi kohort retrospektif untuk mengetahui hubungan penanda inflamasi perifer terhadap gejala klinis, edema peritumoral, dan rekurensi meningioma di RSUPN Cipto Mangunkusumo pada Januari 2016-Desember 2019. Penanda inflamasi perifer diambil dari data hitung jenis, edema peritumoral dihitung langsung dari data radiologi, dan data lainnya diambil dari catatan rekam medis. Analisis data bivariat Chi Square dan Mann Whitney, dilanjutkan dengan analisis multivariat regresi logistik.
Hasil: Pada penelitian ini diperoleh 173 subjek dengan rata-rata usia 46,98±8,26 tahun. Meningioma didominasi derajat I (94,2%) dengan meningothelial merupakan histologi terbanyak. Nyeri kepala merupakan klinis terbanyak (64,7%) diikuti gangguan penglihatan (59%). Nilai titik potong NLR (neutrophil lymphocyte ratio) adalah 2,415 dan MLR (monocyte lymphocyte ratio) 0,295. Klinis yang berhubungan dengan NLR dan MLR yang lebih tinggi adalah nyeri kepala (p<0,001). NLR dan MLR tinggi juga berhubungan dengan gambaran peritumoral edema (p<0,001). Faktor-faktor yang memengaruhi rekurensi adalah edema peritumoral, NLR, MLR, dan derajat simpson. Dari faktor-faktor tersebut, yang berhubungan secara independent adalah MLR dengan aOR 12,647 (IK 95% 2,355-67,919); p: 0,003.
Kesimpulan: NLR dan MLR sebagai faktor penanda inflamasi perifer memiliki median yang lebih tinggi pada pasien meningioma dengan nyeri kepala dan gambaran edema peritumoral. Inflamasi pada meningioma juga berhubungan dengan kejadian rekurensi.

Background: Meningioma, like the other tumors, have the ability to cause inflammation like other tumors. It is located in areas without blood brain barrier and make the inflammation in this tumor microenvironment to be more depicted in peripheral blood than intraparenchymal tumors. This fact provable by the higher levels of c-reactive protein in meningiomas compared to intraaxial tumors even though the low grade of meningiomas. Therefore, this study aimed to determine the relationship between peripheral inflammatory activation based on NLR and MLR with clinical symptoms, peritumoral edema, and meningioma recurrence.
Methods: This is retrospective cohort study to determine the relationship between peripheral inflammatory markers and clinical symptoms, peritumoral edema, and meningioma recurrence at Cipto Mangunkusumo General Hospital in January 2016-December 2019. Peripheral inflammatory markers were taken from type count data, peritumoral edema was calculated directly from radiological data. , and other data taken from medical records. Chi Square and Mann Whitney bivariate are used for data analysis, followed by multivariate logistic regression analysis
Results: 173 subjects were obtained with an average age of 46.98 ± 8.26 years. Subject predominately grade I (94,1%) with meningothelial is the most common histology. Headache was the most clinical manifestation (64,7) followed by visual disturbances (59%). The cut-off point for the NLR is 2.415 and the MLR is 0.295. The clinical association with higher NLR and MLR was headache (p<0.001). High NLR and MLR were also associated with features of peritumoral edema (p<0.001). Factors for tumors recurrence were peritumoral edema, NLR, MLR, and Simpson's grade. Of these factors, which were independently related were MLR with an aOR of 12.647 (95% CI 2.355-67.919); p: 0.003.
Conclusion: NLR and MLR as markers of peripheral inflammation had a higher median in meningioma patients with headache and peritumoral edema features. Inflammation in meningiomas is also associated with recurrence.
