Abstract

Breast cancer has emerged as the most common cancer-related mortality among women worldwide. Therefore, early cancer detection using biomarkers such as microRNA is needed. One of microRNAs that has an important role in breast cancer development is miR-155. Hsa-miR-155-5p is an oncomir that is commonly dysregulated in breast cancer. This study aims to determine the expression of hsa-miR-155-5p in breast cancer patient’s plasma before and after chemotherapy. We collected 64 samples from breast cancer patients admitted to Dr. Sardjito Hospital in Yogyakarta. RNA from plasma was extracted using RNA Isolation Kit miRCURY-Biofluid. cDNA synthesis was performed using cDNA Synthesis kit II and quantification of miR-155-5p using ExiLent SYBR Green master mix (Exiqon). qRT-PCR results were then analyzed with Livak's method and compared (before and after chemotherapy) with t-test. Expression of miR-155-5p in the breast cancer patients’ plasma after chemotherapy was significantly increased (10.59 times) when compared to before chemotherapy (p = 0.001). We concluded that there was upregulated expression of miR-155-5p after chemotherapy than before chemotherapy. There has not been a known, relevant pathway between hsa-miR-155-5p and chemotherapy regimens nor resistance to chemotherapy. Keywords: Breast cancer, plasma, hsa-miR-155-5p, oncomiR, chemotherapy.

Abstract

Dental caries is a major problem in children's mouths that can be avoided if they are taught to take care of their teeth and gums from a young age. Elementary school age is ideal for instilling the habit of brushing teeth, and the school's role becomes increasingly important, one of which is the School Dental Health Centre (UKGS). The UKGS, on the other hand, has not been going well at four elementary schools in Karangtengah Village. As a result, a revitalization program for the UKGS is required. Counseling and toothbrushing movements, as well as dental and oral health checks, are all part of the UKGS revitalization program. The purpose of this program is to increase the knowledge of teachers and UKGS supervisors about UKGS and dental and oral health. This activity began with a pre-test followed by the presentation of UKGS revitalization material and ended with a post-test. This education is able to increase the knowledge of teachers and UKGS supervisors about UKGS and dental and oral health.

Abstract

Dental caries in children is a serious problem that can be caused by a lack of knowledge, attitudes and actions of parents about maintaining oral health. Empowering posyandu cadres is an effort to prevent dental caries in children. One instrument that can be used is the Healthy Teeth Card (KMGS) to monitor the growth and development of children's teeth from 1 to 60 months of age. This service activity aims to increase the role of posyandu cadres as Dental and Oral Health Cadres (KADEGI) in the growth and development of toddler teeth through KMGS in Karangtengah Village, Baturaden District. This community service implementation method begins with simple socialization and training for 29 posyandu cadres. The next stage is the process of assisting posyandu cadres in filling out the KMGS at Posyandu Munthuk and Karangbatur. The result of this programme is a total of 66 toddlers examined by cadres using the KMGS.

Abstract

Chronic periodontitis is a progressive inflammatory disease of the supporting tissues of the teeth caused by dental plaque bacteria with a clinical sign of periodontal pockets. A Gram-negative bacterium that can trigger this inflammatory disease is Porphyromonas gingivalis. Antimicrobial photodynamic therapy with blue LED light irradiation and photosensitizer erythrosine can reduce the survival rate of P. gingivalis. This study aimed to determine the effects of antimicrobial photodynamic therapy (APDT) exposure with blue LED light irradiation and PS erythrosine on the number of macrophages, lymphocytes, and gingival fibroblasts in gingival tissue of Sprague Dawley rats as chronic periodontitis models. This study used a posttest-only control group design to examine 27 Sprague Dawley rats which were divided into P group (healthy rats), N group (untreated chronic periodontitis rats), and PDT groups (chronic periodontitis model given 1 mg/ml PS erythrosine and irradiated with blue LED light for 60 seconds). Cell observation of histologic preparations of rat gingival tissue with hematoxylin-eosin (H&E) staining was carried out on the 1st, 3rd, and 5th days. Histological preparations of gingival tissue with H&E staining was carried out on the 1st, 3rd, and 5th days. Statistical analysis used a one-way ANOVA and the Kruskal-Wallis test, continued with LSD and the Mann-Whitney post-hoc tests. Results showed significant difference in the mean of macrophages in the PDT group compared to the untreated chronic periodontitis group on the 1st, 3rd, and 5th days (p < 0.05). The mean lymphocyte in the PDT group was significantly different from the untreated chronic periodontitis group on the 1st, 3rd, and 5th days (p < 0.05), and significantly lower than that in the healthy group (p < 0.05) but only on the 3rd and 5th days. The mean fibroblast in the PDT group was significantly different compared to the untreated chronic periodontitis group on the 1st, 3rd, and 5th days (p < 0.05). In conclusion, there were significant differences in the number of macrophages, lymphocytes, and fibroblasts in a chronic periodontitis rat model after treatment with APDT exposure with blue LED and erythrosine photosensitizer.

Abstract

Osteoblasts are important for orthodontic tooth movement because they influence the activity of bone formation on the tension area. The administration of natural ingredients such as black cumin is proven to increase the number of osteoblasts because it contains thymoquinone as antioxidants to accelerate the process of tooth movement. The study aims to determine the differences in osteoblast count and their effect on the orthodontic movement of teeth after oral administration of black cumin. The method used in this research is experimental laboratory in vivo with a randomized post-test only control group design using 16 male Sprague-Dawley rat samples that were devided into four groups: the control group (K) with distilled water for 7 and 14 days, also the treatment group (P) with black cumin (Nigella sativa) for 7 and 14 days Elastomeric separators were placed on the upper jaw central incisors (right central incisor) using a separator applier to provide orthodontic mechanical force conditions. Alveolar bone tissue samples were taken after treatment then the number of osteoblasts was calculated histologically. Data were anaylzed using One Way Anova Test and LSD (p<0.05). Result of this research indicated that there was an increase in the number of osteoblasts in orthodontic movement after oral administration of black cumin.

Abstract

Dental biofilm is a bacterial colonization adhering to the tooth surface, enveloped by an extracellular matrix. This biofilm shields bacteria from the body's defense and antibacterial systems, potentially leading to various dental and oral diseases.Staphylococcus aureus is among the bacteria forming dental biofilm. Red onion peel is known to contain flavonoids, saponins, tannins, steroids and alkaloids which have antibacterial and anti-biofilm activity. This study aimed to determine the potential of shallot peel extract in degrading S. aureus biofilms. This study was conducted with a posttest-only control group design. Red onion peel extraction is carried out using the maceration method. A total of 5 groups of extracts (50%, 25%, 12.5%, 6.25%, and 3.12%), positive control (chlorhexidine gluconate 0.2%), and negative control (DMSO 1%) were tested for their activity in S. aureus biofilm degradation at 24 and 48 hours of incubation. The biofilm degradation was assessed using the microtiter plate assay method with crystal violet staining read at a wavelength of 595 nm. Percent biofilm degradation was statistically analyzed using Two way ANOVA and LSD. The results indicated significant differences based on treatment, incubation time, and the interaction between the two. The highest activity was observed at a concentration of 25%, although it was still lower than that of positive control. Conclusion: the ethanol extract of red onion peel has the potential to degrade S. aureus biofilms, with the highest activity at a concentration of 25% and an incubation time of 48 hours.
