Abstract

The cleft lip and aisle (CL/P) are a craniofacial malformation caused by genetic mutations, environmental factors, or an interaction between the two. The development of the lip and auricle involves morphogenesis, molecular signaling pathways, mesenchymal-epithelial interactions, and auricle fusion. CL/P events involve initiation, growth, morphogenesis, and auctioning fusion. The Genome-Wide Association Study (GWAS) identified genes and loci associated with non-syndromic CL/P into 43 types significantly associated with single nucleotide polymorphism (SNP) near the gene. This systematic review aims to explore the genetic underpinnings of CL/P by analyzing findings from Genome-Wide Association Studies (GWAS) and identifying key genes and molecular pathways involved in palatogenesis. The most significant genes and loci in non-syndromic CL/P were Interferon regulatory factor 6 (IRF6), MAF bZIP transcription factor B (MAFB), Paired Box 7 (PAX7), Forkhead Box E1 (FOXE1), Msh Homeobox 1 (MSX1), T-box transcription factor 22 (TBX22), and Methylenetetrahydrofolate reductase (MTHFR). Genetic factors play an essential role in the pathogenesis of non-syndromic CL/P, including disruption of signaling pathways. IRF6, MAFB, PAX7, FOXE1, MSX1, TBX22, and MTHFR are genes that play a role in palatogenesis. Mutations in these genes have an impact on orofacial development.

Abstract

Background: This study aims to determine the appropriate preparation of simple PRP protocol to yield the maximum growth factor concentration, specifically for PDGF and TGF-β1. Methods: Blood samples were collected from 5 healthy volunteers who signed informed consent for participation in the study. The samples then processed by single centrifugation at 4 four different speed (600, 800, 1000, and 1200 rpm) for 4 different centrifugation times ( 8, 10, 12, 14 minutes). The Platelet Derived Growth Factor (PDGF) and Transforming Growth Factor β1 (TGF- β1) concentrations were determined by enzyme-linked immunosorbent assay (ELISA). Blood routine test analysis were measured by hematology analyzer. Results: The 8 min with 600 rpm centrifugation protocol resulted in a slightly greater release of TGF-β1 (7,127 ng/mL) and PDGF (473,909 pg/mL). While the other samples resulted from 50,296 pg/mL (14 min with 1200 rpm) until 406.883 pg/mL (8 min with 800 rpm) of PDGF. The other results of TGF-β1 vary from 0,558 ng/mL (14 min with 1200 rpm) to 6,322 ng/mL (10 min with 600 rpm). Conclusion: The highest concentration of PDGF and TGF-β1 were obtained from centrifugation process at 600 rpm for 8 minutes. Meanwhile, the lowest concentration of PDGF and TGF-β1 were obtained from centrifugation process at 14 min with 1200 rpm.

Abstract

Background: Partial thickness wounds refer to the damage that extends from the epidermis to the upper layers of dermis. This study aims to compare the histological regrowth of acute partial thickness wounds following application of lyophilized amniotic membrane, tulle grass dressing and topical gentamicin. This study aims to establish a standard approach for treating partial thickness wound. Methods: Three groups of Mus Musculus mice were used in our experimental study. Similar to harvesting split thickness skin grafts, partial thickness wounds are performed. The wound was then treated with lyophilized amniotic membrane, tulle grass dressing and topical gentamicin. Using the Scoring System for Histological Assessment of Wound Healing, the wound is histopathologically examined at day 14. In this study, One way Anova was used for statistical analysis. Results: Application of lyophilized amniotic membrane showed different histological characteristic of healing from other method, with p=0.001 it showed significance epidermal growth compared to topical gentamicin. Whereas dermal thickness were also better, accompanied by lower dermal collagen density. Amniotic membrane has a large source of stem cells and contains several growth factors which is important in the physiological process of wound healing and tissue regeneration. Conclusions: Characteristic of skin healing using lyophilized amniotic membrane showed rapid epidermal growth and gave impression of less fibrosis tissue, so that would be potential for better wound treatment especially for prevention of scar.
