    Kesempatan untuk membicarakan maupun mempopulerkan lagu pop dangdut cukup luas. Bisa melalui penayangan di televisi baik swasta maupun pemerintah, melalui mass media surat kabru;majalah,tabloid, pagelaran langsung, hasil penelitian, seminru; bahkan akhir-akhir ini melaui popularitas pejabat-pejabat pemerintahan. Hal ini dapat dibenarkan, timbulnya niat seperti itu bukan ingin menyelaraskan diri dengan zaman, melainkan adanya keinginan untuk menyelamatkan maupun mengembangkan sebagian besar unsur budaya tradisional. Walaupun kenyataannya, sekarang musik dangdut sudah dipengaruhi oleh berbagai musik etnik lokal dan negara luar: Adanya penambahan unsur yang berasal dari luar dimaksudkan, agar persepsi orang tentang musik dangdut yang berbau kampungan mulai bekurang. Ahir-akhir ini orang masih melestarikan pendapat itu, bahwa musik dangdut adalah musik pinggiran kota atau musik orang yang status sosial ekonominya dari menengah ke bawah

    Objective To evaluate the feasibility and accuracy of implementing three-dimensional virtual surgical planning (VSP) and subsequent transfer by additive manufactured tools in the secondary reconstruction of residual post-traumatic deformities in the midface. Methods Patients after secondary reconstruction of post-traumatic midfacial deformities were included in this case series. The metrical deviation between the virtually planned and postoperative position of patient-specific implants (PSI) and bone segments was measured at corresponding reference points. Further information collected included demographic data, post-traumatic symptoms, and type of transfer tools. Results Eight consecutive patients were enrolled in the study. In five patients, VSP with subsequent manufacturing of combined predrilling/osteotomy guides and PSI was performed. In three patients, osteotomy guides, repositioning guides, and individually prebent plates were used following VSP. The median distances between the virtually planned and the postoperative position of the PSI were 2.01 mm (n = 18) compared to a median distance concerning the bone segments of 3.05 mm (n = 12). In patients where PSI were used, the median displacement of the bone segments was lower (n = 7, median 2.77 mm) than in the group with prebent plates (n = 5, 3.28 mm). Conclusion This study demonstrated the feasibility of VSP and transfer by additive manufactured tools for the secondary reconstruction of complex residual post-traumatic deformities in the midface. However, the median deviations observed in this case series were unexpectedly high. The use of navigational systems may further improve the level of accuracy

    High resolution MRI for quantitative assessment of inferior alveolar nerve impairment in course of mandible fractures: an imaging feasibility study

    The purpose of this study was to evaluate a magnetic resonance imaging (MRI) protocol for direct visualization of the inferior alveolar nerve in the setting of mandibular fractures. Fifteen patients suffering from unilateral mandible fractures involving the inferior alveolar nerve (15 affected IAN and 15 unaffected IAN from contralateral side) were examined on a 3 T scanner (Elition, Philips Healthcare, Best, the Netherlands) and compared with 15 healthy volunteers (30 IAN in total). The sequence protocol consisted of a 3D STIR, 3D DESS and 3D T1 FFE sequence. Apparent nerve-muscle contrast-to-noise ratio (aNMCNR), apparent signal-to-noise ratio (aSNR), nerve diameter and fracture dislocation were evaluated by two radiologists and correlated with nerve impairment. Furthermore, dislocation as depicted by MRI was compared to computed tomography (CT) images. Patients with clinically evident nerve impairment showed a significant increase of aNMCNR, aSNR and nerve diameter compared to healthy controls and to the contralateral side (p < 0.05). Furthermore, the T1 FFE sequence allowed dislocation depiction comparable to CT. This prospective study provides a rapid imaging protocol using the 3D STIR and 3D T1 FFE sequence that can directly assess both mandible fractures and IAN damage. In patients with hypoesthesia following mandibular fractures, increased aNMCN R, aSNR and nerve diameter on MRI imaging may help identify patients with a risk of prolonged or permanent hypoesthesia at an early time

    Bone regeneration of minipig mandibular defect by adipose derived mesenchymal stem cells seeded tri-calcium phosphate- poly(D,L-lactide-co-glycolide) scaffolds

    Reconstruction of bone defects represents a serious issue for orthopaedic and maxillofacial surgeons, especially in extensive bone loss. Adipose-derived mesenchymal stem cells (ADSCs) with tri-calcium phosphates (TCP) are widely used for bone regeneration facilitating the formation of bone extracellular matrix to promote reparative osteogenesis. The present study assessed the potential of cell-scaffold constructs for the regeneration of extensive mandibular bone defects in a minipig model. Sixteen skeletally mature miniature pigs were divided into two groups: Control group and scaffolds seeded with osteogenic differentiated pADSCs (n=8/group). TCP-PLGA scaffolds with or without cells were integrated in the mandibular critical size defects and fixed by titanium osteosynthesis plates. After 12 weeks, ADSCs seeded scaffolds (n=7) demonstrated significantly higher bone volume (34.8%+/- 4.80%) than scaffolds implanted without cells (n=6, 22.4%+/- 9.85%) in the micro-CT (p < 0.05). Moreover, an increased amount of osteocalcin deposition was found in the test group in comparison to the control group (27.98 +/- 2.81% vs 17.10 +/- 3.57%, p < 0.001). In conclusion, ADSCs seeding on ceramic/polymer scaffolds improves bone regeneration in large mandibular defects. However, further improvement with regard to the osteogenic capacity is necessary to transfer this concept into clinical use

    Émissions de gaz Ă  effet de serre de la production combinĂ©e de lait et de viande

    Get PDF
    En Suisse, la production combinĂ©e de lait et de viande dans le secteur du bĂ©tail bovin est d’une importance considĂ©rable. La prĂ©sente Ă©tude a modĂ©lisĂ© les Ă©missions de gaz Ă  effet de serre (GES) par vache et par annĂ©e Ă  l’aide de donnĂ©es de rĂ©fĂ©rence suisses, en tenant compte des diffĂ©rents niveaux de performance laitiĂšre et des rendements en viande. L’impact sur les Ă©missions de GES d’une utilisation combinĂ©e de semence sexĂ©e et de matĂ©riel gĂ©nĂ©tique de races Ă  viande a en outre Ă©tĂ© Ă©valuĂ©e. Les analyses ont montrĂ© que le rapport entre production de lait et de viande d’une vache Ă  deux fins avoisine les 24 (24 kg de lait pour 1 kg de viande), ce qui est proche du ratio de la production suisse, tant en 2017 que les annĂ©es prĂ©cĂ©dentes. Sous l’angle de la performance laitiĂšre uniquement, les Ă©missions de GES par vache de rĂ©fĂ©rence et par annĂ©e sont plus Ă©levĂ©es pour une vache Ă  deux fins (9226 kg d’équivalent CO2) que pour une vache Ă  haut rendement (5842 kg). Cependant, sous l’angle de la performance Ă  la fois laitiĂšre et bouchĂšre, les Ă©missions de CO2 des vaches Ă  deux fins sont plus faibles que celles des vaches de type laitier. En revanche, si les vaches laitiĂšres sont insĂ©minĂ©es avec de la semence sexĂ©e pour la remonte et avec du matĂ©riel gĂ©nĂ©tique de races Ă  viande pour toutes les autres saillies, alors les Ă©missions de CO2 des vaches ayant une performance laitiĂšre annuelle de 10 000 kg (soit 8787 kg d’équivalent CO2) sont infĂ©rieures Ă  celles des vaches Ă  deux fins. Pour mĂ©nager le climat, les programmes d’insĂ©mination devraient combiner rigoureusement l’emploi de semence sexĂ©e et de matĂ©riel gĂ©nĂ©tique de races Ă  viande. Dans les rĂ©gions de montagne ou les exploitations biologiques, il est judicieux de travailler avec des races Ă  deux fins
