Simple structure and organs model of fish used to help students collage in observing fish organ structure in Ichtiology practicum. In fact, there are many observers found difficulties to learn fish organs structure. During the practicum, there are several part of organs that cannot be clearly seen or too small. Moreover, it happened for the fishes that has small size. Another, If the organ structure is not in a good condition it will be difficult to be observed. As a replecement, observer can see dan observe by using tool model to see inside organs of fish. Beside, it make PJMK/Assistant to explain inside part of fish organ structure. Simple structure and organs model of fish is validated by academic civitas that have expertised in fisheries. The result was very worthy to be used in learning process in inchtiology practicum. Score that has been gotten is 100 %. In the class observation, it included 100 observer of Ichtiology. The result of the questionair are: the interesting of fish shape model is 72% was very satisfied. Model, tool design, accessories and completeness of tool model is 70% was satisfied. The beneficial of the ichtiology praticum is 80% was helped. The corellation of tool and praticum material ichtiology 80%.

Epigenetic Alterations in Keloid a Possible Method to Find Novel Agents for Keloid Treatment
Background: Keloids are dermal fibro-proliferative disorders due to prolonged wound healing processes with excessive collagen depositions, which produce symptoms of itching and pain, cosmetic disfigurement, and limitation of joint motion. Standard treatment for keloid has not been accepted yet. It may be due to the complexities and poorly understood keloid development that are driven by various factors from systemic to local, genetic to epigenetic. Since genetic factors are difficult to manipulate, an approach to epigenetic factors may be hopeful. Purpose: To review various related reports on epigenetic factors such as DNA methylations, histone modifications, and micro-RNAs, which have significant roles in keloid development and can be used as targets for novel agents in keloid treatment. Review: Various genes in keloid fibroblasts (KFs) are repressed by DNA methylation, and one of them can inhibit the regulation of TGF-β1/Smad signaling, whereas another gene may influence anti-fibrotic events. Either inhibitor of methyl-transferase, inhibitor of histone-acetyltransferase, or histone-deacetylase can reduce TGF-β1/Smad signaling in KFs. Abnormal expressions of pro-fibrotic miRNAs have been identified in KFs and transfection KFs with anti-fibrotic miRNAs such as miRNA-205 and miRNA- 31, evidently can inhibit VEGF signaling. Furthermore, transfection of miRNA-637 into KFs can inhibit KFs in proliferation, migration, and collagen synthesis through TGF-β1/Smad signaling. Apoptosis and cellular senescence in KFs can also be stimulated by miRA-34 and miRNA-30. Conclusion: In the future, targets in epigenetic events such as inhibitors of methyl-transferase, histone-acetyltransferases, and histone-deacetylases, together with various miRNA, may be applied as novel agents for the treatment of keloid

Pathogenesis, evaluation, and recent management of diabetic foot ulcer
Diabetic foot ulcers (DFUs) are a major health problem as the number of patients continues to increase, are difficult to heal, require enormous management costs, and deteriorate the quality of life of patients, their families and societies. The pathogenesis of DFUs is complex. Most important factors that increase the risk of DFUs are peripheral neuropathy, foot deformities, frequent minor trauma, and peripheral arterial disease. Neuropeptides derangement, hypoxia, hyperglycemia, and infection act as the cause of chronicity of DFUs. Therefore, during the initial evaluation of DFU, patients need to be checked for their metabolic status, presence or absence of peripheral neuropathy, vascular insufficiency, foot deformities, and infection of the ulcer and its underlying bone. Then, DFUs are classified by the severity of vascular insufficiency, the depth of the wound, and the severity of the infection. This classification system helps clinicians to determine whether the patient needs to be hospitalized or amputated and helps to establish DFU management strategies. In the management of DFUs, adequate blood flow to the wound area should be achieved. Glycemic control and standard wound care should be encouraged. Standard wound care includes debridement, offloading, wound moisture balance with suitable dressing, edema control, and infection control. Education about preventive foot care should be taught to the patients and their families. As the pathogenesis and management of DFUs are complex, a multidisciplinary team consists of expert individuals in their respective fields should be involved
