    Penelitian ini dilatarbelakangi oleh kurangnya pemahaman, penerimaan, dan sikap orang tua terhadap hambatan yang dihadapi anak. Hal ini berdampak pada kemampuan keluarga dalam memberikan layanan intervensi dini di rumah. Tujuan dari penelitian ini adalah untuk merumuskan program intervensi dini bersumber daya keluarga yang akan menjadi pedoman orang tua dalam melaksanakan intervensi. Penelitian ini menggunakan pendekatan kualitatif dengan metode deskriptif. Subjek dalam penelitian ini adalah satu keluarga yang memiliki anak Cerebral Palsy dengan hambatan komunikasi di Ciamis. Teknik pengumpulan data yang digunakan adalah observasi, wawancara, dan studi dokumentasi. Hasil penelitian menunjukkan bahwa: 1) anak memiliki hambatan komunikasi yang pencapaian perkembangan komunikasi verbalnya setara dengan anak usia 2-3 tahun dan usia kalender saat ini 5 tahun. 2) rendahnya tingkat pemahaman orangtua terhadap hambatan anak. 3). Rumusan program intervensi dini bersumber daya keluarga ini berdasarkan kondisi objektif serta kebutuhan keluarga dan anak. 4). tingkat pemahaman orang tua mengenai hambatan anak meningkat serta terjadi perubahan sikap dan perilaku orang tua kepada anak;--- The study was motivated by the lack of understanding, acceptance as well as the attitude of the parents toward their child’s obstacles. It somehow has an impact on family’s capacity to give early intervention support at home. This study was aimed at formulating an early intervention program to the child. The study used descriptive qualitative method involving a single family having a child suffering from Cerebral Palsy causing communication barrier at Ciamis. The techniques used in collecting the data were observations, interviews, and document analysis. The study revealed several findings as follows: 1) the child had communication barrier which made her communication verbal developmental stage was equal to 2-3 years old children. 2) The lack of understanding, acceptance and attitude of the parents toward their child’s communication barrier as well as the support in delivering early intervention at home. 3) The early intervention family-based program’s formulation was based on the objective condition as well as the needs’ of both the child and the parents. 4) The level understanding parents of the barriers to child increase and a change in attitudes and behavior of parents to child

    Mechanical induction of the tumorigenic b-catenin pathway by tumour growth pressure

    International audienceThe tumour microenvironment may contribute to tumorigenesis owing to mechanical forces such as fibrotic stiffness or mechanical pressure caused by the expansion of hyper-proliferative cells 1,2. Here we explore the contribution of the mechanical pressure exerted by tumour growth onto non-tumorous adjacent epithe-lium. In the early stage of mouse colon tumour development in the Notch 1 Apc 1/1638N mouse model, we observed mechanistic pressure stress in the non-tumorous epithelial cells caused by hyper-proliferative adjacent crypts overexpressing active Notch, which is associated with increased Ret and b-catenin signalling. We thus developed a method that allows the delivery of a defined mechanical pressure in vivo, by subcutaneously inserting a magnet close to the mouse colon. The implanted magnet generated a magnetic force on ultra-magnetic liposomes, stabilized in the mesench-ymal cells of the connective tissue surrounding colonic crypts after intravenous injection. The magnetically induced pressure quantitatively mimicked the endogenous early tumour growth stress in the order of 1,200 Pa, without affecting tissue stiffness, as monitored by ultrasound strain imaging and shear wave elastography. The exertion of pressure mimicking that of tumour growth led to rapid Ret activation and downstream phosphorylation of b-catenin on Tyr654, imparing its interaction with the E-cadherin in adhe-rens junctions, and which was followed by b-catenin nuclear trans-location after 15 days. As a consequence, increased expression of b-catenin-target genes was observed at 1 month, together with crypt enlargement accompanying the formation of early tumorous aberrant crypt foci. Mechanical activation of the tumorigenic b-catenin pathway suggests unexplored modes of tumour propagation based on mechanical signalling pathways in healthy epithelial cells surrounding the tumour, which may contribute to tumour heterogeneity. To test the tumorous impact of early tumour growth pressure on non-tumorous epithelial tissues in vivo, apart from the mechanical stiffness characteristic of the microenvironment of late tumours 1-
