Abstract

Genetic instability may underlie the etiology of multistep carcinogenesis. The altered p53 gene observed in tumors may represent the expression of such instability and may allow the accumulation of other gene alterations caused by multiple mechanism. p53 gene is the guardian of the genome, that is why we pay more attention to this gene. In this study, we evaluated the significance of p53 mutation in 55 patient with oral squamous carcinoma. Thirty among them underwent well-differentiated carcinoma, while the remaining 25 patientsunderwent poorly differentiated carcinoma. The mutations were detected by PCR-SSCP (Single strand Conformational Polymorphism) analysis in the region between exon 5 and exon 8. The results indicated that the p53 mutation in exon 5 (40%), exon 6 (28%), exon 7 (24%) and exon 8 (8%) were associated with poorly differentiated carcinoma, whereas mutation in exon 5 (10%), exon 6 (30%), exon 7 (40%) and exon 8 (20%) were associated with well-differentiated carcinoma. These observations suggest that p53 mutation in exon5, 6, and 7 have strong correlation with poorly differentiated in oral squamous carcinoma while well-differentiated level was related with mutation in exon 6,7 and 8.

Abstract

The rapid epidemic growth of HIV is continuing in Indonesia. There are some factors which have influenced the spreading of this epidemic in Indonesia, such as the poor awareness to avoid unsafe free sex attitude and the sharing of needles and syringes among intravenous drug users (IDUs). The sexual transmission of HIV has also apparently increased in Tulungagung. Commercial sex workers play a significant role in the spread of HIV in Tulungagung. People in Tulungagung have worked at other countries as Indonesian migrants. This condition can cause the increase number of HIV-1 case and the possibility of genetic variation (subtype) HIV-1 in Tulungagung. This research is aimed to analyze the subtype and to determine estimation of transmission mode on infected patient of HIV-1 and AIDS who came to Seruni clinic Dr. Iskak hospital in Tulungagung. 40 HIV?AIDSpatients were interviewed to determine the subtype and the transmission mode. The results showed that 14 of 40 plasma samples (35%) were successfully to amplified and sequenced. OverallCRF01-AE wereidentified as predominant subtype among HIV/AIDS patients in Tulungagung. Based on individual information, 31 of 40 subjects (77%) were heterosexual transmission.

Abstract

Orthopedic face mask has been introduced for more than 100 years ago, however, it is primarily indicated for growingpatients. Its effectiveness in adult patients is still questionable. It is thought that in non growing adults the degree oforthopedic movement is minimal, whether dental movement i s more prominent. In addition, there is still controversial,whether patients’ compliance or the existent skeletal growth determines the treatment success. The objective of this studywas to propose a new concept for adult orthopedics face mask therapy ba sed on functional and biological mechanismsinvolved in dentofacial remodeling . Conventional face mask therapy only depended on duration, magnitude andunidirectional elastic forces. In the reviewed case report, the inspiration for a new concept was evolv ed from themultidirectional forces which were resulted from continuous functional movements (i.e. chewing and speaking) duringwearing face mask. These movements may lead to stimulate additional orthopedic or skeletal movements in adult patient.The expla nation of this phenomenon could be explained not only by clinical result, but also with the biologicalmechanism of bone remodeling. In conclusion, regarding to the successful treatment result and its logical biologicalexplanation, this new concept to inc rease the effectiveness of adult orthopedic face mask therapy is likely.

Abstract

Since March 2020, the case of coronavirus disease or known as Covid-19, has become a global pandemic. According to UNESCO, schools are closed in about 100 countries due to a public health emergency, including Indonesia. The condition forces teachers to make the transition of the way they teach from face to face learning to online learning. This study investigated EFL teachers’ Perception of online English language learning. Their perceptions were analyzed in three aspects: perceived usefulness, perceived ease of use, and their attitude toward online English language learning. This study employed a descriptive design with a qualitative approach. A survey questionnaire and interview were used in this study to elicit the responses of 102 Junior High School English teachers in Bandung. This study's findings revealed that the participants showed a positive perception of the usefulness and ease of use of online learning systems during pandemic Covid-19. Still, more than half of the teachers didn’t agree on the effectiveness of it. Even though the teachers face many online teaching problems, they could show the right attitude toward using technology to teach online.

Abstract

ABSTRACTBackground: Alveolar bone resorption can occur after tooth extraction. One source of bone scaffold material is hydroxyapatite and tricalcium phosphate (HA-TCP). The shell of Anadara granosa can be synthesized to be HA-TCP. Hyaluronic acid, which is widely contained in Stichopus hermanni, can stimulate endothelial progenitor cells for the healing process. Purpose: This research aims to prove the Effectivity of scaffold from Anadara granosa shell-Stichopus hermanni on blood vessel counts after tooth extraction. Methods: The sample in this study was male Wistar rats divided into four study groups randomly. Each group consists of 6 rats. Extraction was carried out on the mandibular first incisor, then was given gelatin as a placebo in the control group, treatment groups given scaffold from Anadara granosa shells (AG), and scaffold combination from Anadara granosa shells-Stichopus hermanni with concentrations of 0.4%-0.8%. (AGSH1-AGSH2). Development of HA-TCP synthesized from Anadara granosa combined with Stichopus hermanni extract for biomedical scaffolds using the freeze-dried method. Observations were made three days after tooth extraction. Data analysis has used one-way ANOVA followed by Tukey HSD (p<0.05). Results: The results of the ANOVA test followed by the HSD-Tukey test showed a significant difference between C (7.33±1.51) and AGSH1 (11.50±1.38), AGSH2 (21.17±1.94), AG (9.33±1.63) and AGSH1 with AGSH2, but between AG and, AGSH1 no significant differences.Conclusions: Combination scaffold from Anadara granosa shell and Stichopus hermanni 0.8% effectively increased blood vessel counts after tooth extraction.

Abstract

Background: Tooth extraction can naturally cause inflammation triggering osteoclast proliferation and alveolar bone resorption. Preservation of the tooth extraction sockets is needed for patients in order to reduce alveolar bone resorption risks. Aloe vera is known to have anthraquinones components, namely Aloin, Aloe emedin, and barbaloin, considered as anti-inflammation. Therefore, to overcome the inflammation, the role of NF-kb is very significant to decrease nuclear factor kappa b (NF-kb). As a result, inflammation risks will be decreased. Purpose: The study was aimed to determine the induction effect of combination of Aloe vera and XCB into tooth extraction sockets to reduce inflammation by reducing NF-kb expression, osteoclasts and osteoblasts. Methods: Forty-eight Cavia cobaya were divided into eight groups, each group consisted of six animals. The mandibular incisors of those Cavia cobaya were extracted and induced with either PEG, XCB, Aloe vera, or the combination of Aloe vera + XCB. Those animals were sacrificed on day 7 and day 30 after the extraction. Then immunohistochemical and histopathology examinations were conducted to observe NF-kb expression, osteoblasts and osteoclasts. Results: It was known that in group induced with the combination of Aloe vera and xenograft concelous bovine, the growth of osteoblasts was high, while NF-kb expression and osteoclasts reduced. Conclusion: It can be concluded that the induction of the combination of Aloe vera and XCB into the tooth extraction sockets can reduce NF-kb expression and osteoclast, as a result, alveolar bone resorption risks decrease, and osteoblast increase.Latar belakang: Trauma mekanis akibat pencabutan gigi asli menyebabkan keradangan. Keradangan memicu proliferasi osteoklas sehingga menyebabkan resorpsi tulang alveolararis. Pada pembuatan gigi tiruan, resorpsi tulang alveolar yang terjadi, sangat tidak diinginkan, sebab resorpsi tulang alveolar mengurangi keberhasilan pembuatan gigitiruan. Diperlukan preservasi soket pencabutan gigi asli pada penderita untuk mencegah terjadinya resorpsi tulang alveolar. Aloe vera mempunyai komponen anthraquinon yaitu aloin, Aloe emodin, barbaloin yang merupakan anti inflamasi yang dapat secara cepat menyembuhkan luka, sehingga berpotensi untuk digunakan pada preservasi soket. Didalam mengatasi keradangan peran NF-kb sangat berarti, sebab penurunan NF-kb akan mengurangi terjadinya inflamasi. tujuan: Penelitian ini bertujuan untuk menguji apakah induksi kombinasi lidah buaya dan XCB ke soket pencabutan gigi dapat mengurangi peradangan dengan mengurangi ekspresi NF - kb , osteoklas dan osteoblast. Metode: Empat puluh delapan ekor Cavia cabaya yang terdiri dari 8 kelompok, tiap kelompok 6 ekor, kelompok pengisian PEG (kontrol), kelompok pengisian XCB, kelompok pengisian aloe vera dan kelompok pengisian kombinasi aloe vera dan XCB, kelompok ini terdiri dari kelompok 7 dan 30 hari, kemudian diperiksa dengan imunohistokimia ekspresi NF-kb dan pemeriksaan histologi untuk osteoblas dan osteoklas. Hasil: Kelompok yang diisi kombinasi Alo vera dan xenograft concelous bovine pada soket pencabutan gigi, menunjukan nilai tertinggi dalam pertumbuhan osteoblas dan penurunan pada ekspresi NF-kb dan osteoklas. Simpulan: Induksi kombinasi Aloe vera dan xenograft concelous bovine pada preservasi soket pencabutan gigi dapat menurunkan ekspresi NF-kB dan osteoklas, menurunkan resiko resorpsi tulang alveolar dan meningkatkan osteoblas.

Abstract

Background: Mitochondrial DNA (mtDNA) sequence analysis of the hypervariable control region has been shown to be an effective tool for personal identification. The high copy and maternal mode of inheritance make mtDNA analysis particularly useful when old samples or degradation of biological samples prohibits the detection of nuclear DNA analysis. Dental pulp is covered with hard tissue such as dentin and enamel. It is highly capable of protecting the DNA and thus is extremely useful. One of the diasadvantages of mitochondrial DNA is heteroplasmy. Heteroplasmy is the presence of a mixture of more than one type of an organellar genome within a cell or individual. It can lead to ambiguity in forensic personal identification. Due to that, the evidence of heteroplasmy in dental pulp is needed. Purpose: The study was aimed to determine the heteroplasmy occurance of mitocondrial DNA in dental pulp. Methods: Blood and teeth samples were taken from 6 persons, each samples was extracted with DNAzol. DNA samples were amplified with PCR and sequencing to analyze the nucleotide sequences polymorphism of the hypervariable region 1 in mtDNA and compared with revised Cambridge Reference Sequence (rCRS). results: The dental pulp and blood nucleotide sequence of hypervariable region 1 mitochondrial DNA showed polymorphism when compared with rCRS and heteroplasmy when compared between dental pulp with blood. Conclusion: The study showed that heteroplasmy was found in mithocondrial DNA from dental pulp.latar belakang: Analisis sekuens DNA mitokondria (mtDNA) regio kontrol hypervariable telah terbukti menjadi alat efektif untuk identifikasi personal. Kopi DNA yang banyak dan pewarisan maternal membuat analisis mtDNA sangat berguna ketika sampel lama atau sampel biologis yang terdegradasi menghambat deteksi analisis DNA inti. Pulpa gigi terlindung jaringan keras seperti dentin dan enamel. Hal ini membuat pulpa mampu melindungi DNA dan dengan demikian sangat berguna untuk identifikasi. Salah satu kekurangan DNA mitokondria adalah heteroplasmy. Heteroplasmy adalah adanya campuran lebih dari satu jenis genom dalam sel atau individua. Hal ini dapat menyebabkan ambiguitas pada identifikasi pribadi forensik. Oleh sebab itu, identifikasi personal menggunakan pulpa gigi harus memperhatikan kejadian heteroplasmy. tujuan: Penelitian ini bertujuan untuk meneliti kejadian heteroplamy DNA mitokondria pada pulpa gigi. Metode: Sampel darah dan gigi diambil dari 6 orang, masing-masing sampel diekstraksi dengan metode DNAzol. Sampel DNA diamplifikasi dengan PCR dan sequencing untuk menganalisis polimorfisme urutan nukleotida di hypervariable region 1 mtDNA dan dibandingkan dengan revised Cambridge Reference Sequence (rCRS). hasil: Sekuens nukleotida pulpa gigi dan darah daerah pada hypervariable region 1 DNA mitokondria menunjukkan polimorfisme bila dibandingkan dengan rCRS dan heteroplasmy bila dibandingkan antara pulpa gigi dengan darah. Simpulan: Penelitian ini menunjukkan bahwa heteroplasmy dapat ditemukan pada DNA mitokrondia pulpa gigi.

Abstract

Background: Squamous cell carcinoma is the most common cancer in the oral cavity. DNA tests showed that almost 90% of cases revealed wild p53 gene mutations. Wild p53 gene mutations cause p53 inactivation so the cell cycle does not stop in G1 phase but continues to S phase and G2 and M, it makes the mutated DNA remains multiplied and apoptosis does not occur. One candidate of the cancer treatment alternatives is pomegranate extract (Punica granatum L – PGL). Purpose: The purpose of study was to examine the effect of PGL on wild p53 expression in oral cavity malignant cell of swiss webster strain mice. Methods: Thirty- two swiss webster strain mice (Balb/c) 5 months old were randomly divided into four groups. Two control groups (K0: no benzopirene exposed and untreated; K1: benzopirene exposed and untreated); and 2 treatment groups (P1: benzopirene exposed and given EA; P2: benzopirene exposed and given PGL extract). The expression of wild p53 was determined by immunohistochemical techniques. Results: The results showed that administration of PGL could increase the expression of wild p53 in malignant epithelial cells in the oral mucosa of mice, and the expression was higher than EA. Conclusion: This study suggested that the PGL extract could express wild p53 in the oral cavity malignant cells of swiss Webster strains mice.Latar belakang: Karsinoma sel skuamosa merupakan kanker yang sering terjadi pada rongga mulut. Pemeriksaan DNA menunjukkan hampir 90% kasus dijumpai adanya mutasi gen wild p53. Mutasi gen wild p53 menyebabkan inaktivasi wild p53 sehingga siklus sel tidak berhenti pada fase G1 tetapi berlanjut ke fase S dan G2 dan M, sehingga DNA yang mengalami mutasi tetap dilipatgandakan dan apoptosis tidak terjadi. Salah satu kandidat obat kanker adalah ekstrak buah delima (Punica Granatum L - PGL). Tujuan: Penelitian ini bertujuan untuk meneliti efek ekstrak PGL terhadap ekspresi wild p53 pada sel ganas rongga mulut mencit strain swiss webster. Metode: Tiga puluh dua ekor mencit (Balb/c) strain swiss webster jantan berumur 5 bulan dibagi secara random menjadi 4 kelompok, yaitu 2 kelompok kontrol (K0: tidak dipapar benzopirene dan tidak diberi perlakuan; K1: dipapar benzopirene dan tidak diberi perlakuan); serta 2 kelompok perlakuan (P1: dipapar benzopirene dan diberi EA; P2: dipapar benzopirene dan diberi ekstrak PGL). Pemeriksaan ekspresi wild p53 dilakukan dengan teknik  imunohistokimia. Hasil: Hasil penelitian menunjukkan bahwa pemberian ekstrak PGL dapat meningkatkan ekspresi wild p53 pada sel epitel ganas pada mukosa rongga mulut mencit, dan lebih tinggi dibanding dengan pemberian EA. Simpulan: Penelitian ini menunjukkan bahwa ekstrak PGL dapat meningkatkan ekspresi wild p53 pada sel ganas rongga mulut mencit strain swiss webster
