Abstract

Nasopharyngeal carcinoma (NPC) is a multifactorial disease that is endemic geographically in the world. Indonesian population has a highly incidence rate that is 6.2/100,000 people year. The pathogenesis of NPC is more directly reflected by carcinoma-specific viral transcriptional activity at the site of primary tumour. Epstein-Barr virus (EBV) infection in NPC is reflected by the expression of EBV latent and lytic gene. In fact, mRNA Latent Membrane Protein 1 (LMP1) EBV expression was an important latent infection biomarker. The aim of this study was to determine a potential use of relative expression of mRNA LMP1 EBV from formalin-fixed paraffin embedded (FFPE) tumour biopsy in NPC as a tumour biomarker. This reseach design was a cross sectional study. The samples were the archived specimens of FFPE tumour biopsy from NPC WHO-3 patient which were collected from untreated patients from 2014 in the Department of Pathology Anatomy, Prof. dr. Margono Soekarjo Hospital, Purwokerto. The expression of mRNA LMP1 EBV expression was determined by RT-PCR technique. The positivity of mRNA LMP1 EBV expression was 51.9%, indicating a moderate positivity. The result proved that the expression of mRNA LMP1 EBV from FFPE NPC WHO-3 tumour biopsy was a potential biomarker of NPC diagnosis. The molecular methods would improved the management of NPC, particularly in the histopathological diagnosis of NPC.

Abstract

Protozoa species of Trichodina spp. may be found in most hatchery centers in Banyumas, Purbalingga, and Banjarnegara. However, the determination of Trichodina spp. types is still based on its body’s morphological variations, not yet molecular. A research has been conducted to identify molekuler of the Trichodina spp. with the infecting 18S rRNA gene marking on the gourami larvae in Exs. Residence of Banyumas, Central Java. The research used a survey method with the samples of gourami. Amplification of 18S rRNA gene from Trichodina heterodentata was Performed using PCR technique. Primer used is Forward primer (5 ‘-AAC CTG GTT GAT CCT GCC ATG-3’) and Reverse primer (5 ‘-TGA TCC TTC TGC AGG TTC ACC TAC-3’) which produces a 600 pb amplicon of DNA. Molecular research can be a complementary identification of organisms morphologically. Amplification of the partial 18S rRNA gene may be used to identify Trichodina specifically. Gourami larvae taken from the hatchery centers in Banyumas, Purbalingga, and Banjarnegara. The results show that the detected percentage of Trichodina heterodentata genes with the infecting 18S rRNA gene marking on the gourami larvae in Central Java taken from the hatchery centers in Banyumas, Purbalingga and Banjarnegara are respectively 10%, 10%, and 45%. This research provides a benefit in mapping the presence of protozoa pathogen of Trichodina spp. in gourami hatcheries in the Former Exs. Residence of Banyumas, Central Java

Abstract

Intercellular adhesion plays a role in cancer formation and protein has a key potential in maintaining cell adhesion, including syndecan-1. Meanwhile, oral cancer originates from the oral epithelium, which has an invasive and metastatic level. Its treatments involving chemotherapy and radiotherapy commonly leave unfavorable side effects, hence, suitable alternatives are needed. Natural ingredients are widely used as an alternative treatment for cancer, for example, Ganoderma lucidum (G. lucidum) which has anti-cancer and anti-angiogenic properties, induces apoptosis, stimulates an immune response, inhibits the degradation of Extracellular matrix (ECM), reduces inflammation, affects cell cycles, cytotoxic, and acts as an antioxidant.This study aims to determine the effect of ethanol extract from Ganoderma lucidum Cianjur isolate on syndecan-1 expression in KB CCL-17 oral cell cancer. This was an experimental study with a post-test only control group design, the treatment group used G. lucidum ethanol extract with a concentration of 2.12 μg/ml (P1), 4.24 μg/ml (P2), and 8.49 μg/ml (P3), while the positive control group used cisplatin with a concentration of 11.5 μg/ml (K1). In contrast, the negative control used aquadest (K0), while syndecan-1 expression was observed using the immunohistochemical examination.The highest syndecan-1 expansion rate was found in the treatment group with a concentration of 8.49 μg/ml. A significant difference was indicated by one-way ANOVA (p<0.05) between K0 - K1, K0 - P1, K0 - P2, K0 - P3, K1 - P1, K1 - P2, K1 - P3, P1 - P2, as well as P1 and P3. The administration of ethanol extract from G. lucidum Cianjur isolate increases syndecan-1 expression in KB CCL-17 oral cell cancer.

Abstract

BACKGROUND: Chronic Suppurative Otitis Media (CSOM) causes hearing impairment and frequently occurred in low-income country where medical care and personal hygiene are poor. Staphylococcus aureus and Pseudomonas aeruginosa are the most common cause of CSOM. We investigated prevalence and antimicrobial susceptibility of S. aureus and P. aeruginosa from tubotympanic CSOM patients in tertiary hospital, Purwokerto, Indonesia in 2016-2017.METHODS: Ear swab specimens were collected from patients with tubotympanic CSOM. S. aureus and P. aeruginosa were isolated and identified by culture, matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), and molecular tools. Antimicrobial susceptibility testing was performed using the disk diffusion method.RESULTS: Out of ear swabs from 34 patients with tubotympanic CSOM, P. aeruginosa and S. aureus were identified in 35%patients. No Methicillin-resistant S. aureus (MRSA) strain was found from the ear swabs of the patients with tubotympanic CSOM. Bacterial identification using the MALDI-TOF MS was concordantly with culture and molecular tools. All S. aureus isolates showed full susceptibility to cefoxitin and trimethoprim-sulphamethoxazole. Resistance to tetracycline was common with only 64% of S. aureus strains being susceptible. Meanwhile, all P. aeruginosa strains were susceptible to cefepime, cetazidime, meropenem, gentamicin, and tobramycin.CONCLUSION: S. aureus and P. aeruginosa are found in patients with tubotympanic CSOM and still susceptible to different antibiotic agents. MALDI-TOF MS demonstrate rapid, accurate and robust to detect S. aureus and P. aeruginosa.KEYWORDS: Staphylococcus aureus, Pseudomonas aeruginosa, chronic tubotympanic suppurative otitis media

Abstract

Background: Nasopharyngeal carcinoma (NPC) is endemic in certain geographic regions, such asSoutheast Asia, and is associated with several environmental and genetic factors. Undifferentiated NPCis consistent with Epstein-Barr virus (EBV) infection. NPC is the most common ENT tumor in Indonesiawith high prevalence among native populations and yearly overall incidence estimated 6.2 per 100.000 population. Purpose: To explain the advantage of EBV immediate-early gene expression analysis indetermining of NPC diagnosis and management of NPC.Review: Replication of EBV implies to twocellular reactions, i.e. latentcy and lytic cycle expression of EBV lytic genes which consists of three lyticphases, i.e. immediate-early, early and late phase. Expression of immediate-early genes BZLF1 andBRLF1 are needed to induct of early and late genes, so both genes are known as transactivator genes.BALF1, an early lytic gene, expresses some protein regulating EBV replication in NPC. Expression of BCLF1, a late lytic gene, is essential for EBV replication, particularly in the forming of virion structure inNPC. Switching from latent to lytic cycle in tumor cells can happened spontaneously, particularly whenthe viral immediate early genes are induced via signal transduction after initial activation by anti-IgG,TGF-ß and CD4+. In NPC, the induction of EBV lytic cycle by cisplatin and irradiation gamma leads tothe increasing expression of BRLF1 and BZLF1 which have a correlation with the increasing of tumorprogression. RT-PCR technique is a very useful for detecting mRNA BRLF1 and BZLF1 gene expressionat the site of primary tumor, while real-time RT-PCR technique is used to measure the mRNA level ofthose genes.Conclusion: Expression of EBV immediate-early lytic gene in the biopsy of NPC primarytumour provides a basic clinical information for NPC diagnosis and therapy more accurately. Key words: expression EBV lytic gene, nasopharyngeal carcinoma, NPC diagnosis. Abstrak : Latar belakang: Karsinoma nasofaring (KNF) bersifat endemik secara geografis (di Asia Tenggara)dan berasosiasi dengan beragam faktor lingkungan dan genetik. KNF tidak berdiferensiasi konsistendengan adanya infeksi virus Epstein-Barr (VEB). Prevalensi KNF pada populasi Indonesia cukup tinggisebesar 6,2/100.000 penduduk per tahun. Tujuan:Menjelaskan kegunaan analisis ekspresi gen litikimmediate-early VEB untuk menegakkan diagnosis KNF dan meningkatkan efisiensi dalam penangananKNF. Tinjauan Pustaka: Replikasi VEB pada epitel nasofaring berimplikasi pada dua reaksi seluler,yaitu siklus laten dan litik VEB. Ekspresi gen litik VEB terdiri dari tiga fase, yaitu immediate-early,early dan late.Ekspresi gen immediate-early BZLF1 dan BRLF1 diperlukan untuk menginduksi genlitik fase early dan late, sehingga kedua gen tersebut dikenal sebagai gen transaktivator. Gen faseearlylitik BALF1 mengekspresikan protein replikasi pada KNF. Ekspresi gen fase late BCLF1 berperanpenting untuk replikasi VEB pada KNF, terutama untuk membentuk struktur virion. Perubahan sikluslaten menjadi siklus litik pada sel tumor dapat terjadi secara spontan, terutama melalui transduksi sinyalsetelah aktivasi oleh anti-IgG, TGF-ß dan CD4. Pada KNF, induksi siklus litik VEB dengan cisplatindan radiasi sinar γ menyebabkan peningkatan ekspresi gen BRLF1 dan BZLF1 yang berkorelasi denganpeningkatan progresivitas tumor. Teknik RT-PCR akan sangat berguna untuk mendeteksi ekspresi mRNAgen BRLF1 dan BZLF1 VEB pada lokasi tumor primer, sedangkan teknik real time RT-PCR digunakanuntuk mengukur kuantitas mRNA gen tersebut. Kesimpulan: Ekspresi gen litik immediate-early VEBpada biopsi tumor KNF memberikan informasi klinis dasar yang lebih akurat untuk diagnosis dan terapiKNF.+Kata kunci: ekspresi gen litik VEB, karsinoma nasofaring, diagnosis KNF.
