Pemanfaatan Lahan Sempit sebagai Tempat Budidaya Ikan Cupang di Mertasinga, Cilacap

Ikan cupang hias (Betta splendens) merupakan ikan hias yang bernilai ekonomis. Ikan ini memiliki keunggulan berupa keindahan warna dan naluri berkelahi serta siklus hidup yang relatif singkat. Ikan cupang masuk ke dalam kategori ikan yang mudah dibudidaya (dapat menggunakan lahan yang sempit dan seadannya). Ikan cupang hias (Betta splendens) merupakan satu diantara 70 spesies ikan cupang (Betta sp.) yang mengalami pengembangbiakkan. Proses tersebut meliputi pengembangan beberapa karakter mulai dari warna tubuh, ukuran dan bentuk sirip, baik untuk tujuan ornamental maupun aduan. Kedua tujuan tersebut, pembudidaya (breeder) biasanya melakukan optimalisasi lahan maupun indukan. Potensi ini dapat diimplementasikan dan dikembangkan kepada pembudidaya baru (new breeder) yang tergabung dalam Komunitas Peternak Cupang Cilacap (KPCC). Kegiatan pengabdian ini diharapkan dapat membantu permasalahan yang ada seperti cara optimalisasi lahan sempit untuk kegiatan budidaya ikan cupang dan penambahan pengetahuan mengenai potensi ikan cupang, khususnya pembudidaya baru (new breeder). Kegiatan ini terdiri dari 2 kelompok warga dan 1 kelompok mahasiswa. Solusi yang diberikan berupa diskusi mengenai prospek budidaya ikan cupang dan pelatihan yang terfokus mulai dari pemilihan indukan, proses pemijahaan, pemeliharaan telur dan larva serta burayak dan pemberian pakan guna meningkatkan semangat berwirausaha. Hasil yang diperoleh dari kegiatan ini, yaitu pemanfaatan lahan untuk tempat budidaya dan keberhasilan proses pemijahan yang menghasilkan individu baru baik oleh warga maupun mahasiswa dengan semangat berwirausaha

Volumetric analysis of the cranial and nasal cavity from micro-computed tomography scans in the rabbit

Background: The aim of the study was to estimate the volume values of the cranial cavity and nasal cavity structures and to compare the efficiency of manual segmentation of three-dimensional reconstruction and Cavalieri’s principle (CP) methodologies. Materials and methods: Volume values of the cranial cavity, maxillary sinus (MS), dorsal conchal sinus (DCS), dorsal nasal meatus (DNM), middle nasal meatus (MNM), ventral nasal meatus (VNM), ventral nasal concha (VNC), middle nasal concha (MNC) and nasal vestibule (NV) were estimated with manual segmentation and CP from micro-computed tomography images in 5 male New Zealand white rabbits. Volume measurements and elapsed time were compared with each other. Three-dimensional reconstruction models of nasal and cranial cavity structures were created. Results: There was a statistically significant difference between methods of the MS, DCS, DNM, MNM, VNM, VNC, and MNC volume measurements. Additionally, there was a statistically significant difference between the volumetric analysis time period of the methods and CP was found much shorter than manual segmentation. Conclusions: Realistic results were achieved in a short time with the CP among the stereology methods. It is thought that these image and quantitative data results can be used for modelling, toxicology and pathology studies such as acute and chronić rhinitis or rhino sinusitis as well as a good understanding of the relationship of the anatomical structures in the nasal cavity

Reduction of the Radiofrequency Heating of Metallic Devices Using a Dual-Drive Birdcage Coil

Cataloged from PDF version of article.In this work, it is demonstrated that a dual-drive birdcage coil can be used to reduce the radiofrequency heating of metallic devices during magnetic resonance imaging. By controlling the excitation currents of the two channels of a birdcage coil, the radiofrequency current that is induced near the lead tip could be set to zero. To monitor the current, the image artifacts near the lead tips were measured. The electric field distribution was controlled using a dual-drive birdcage coil. With this method, the lead currents and the lead tip temperatures were reduced substantially [<0.3 C for an applied 4.4 W/kg SAR compared to >4.9 C using quadrature excitation], as demonstrated by phantom and animal experiments. The homogeneity of the flip angle distribution was preserved, as shown by volunteer experiments. The normalized root-mean-square error of the flip angle distribution was less than 10% for all excitations. The average specific absorption rate increased as a trade-off for using different excitation patterns. Magn Reson Med 69:845–852, 2013. VC 2012 Wiley Periodicals, In

Teratogenic risk and contraceptive counselling in psychiatric practice: analysis of anticonvulsant therapy

&lt;p&gt;Background: Anticonvulsants have been used to manage psychiatric conditions for over 50 years. It is recognised that some, particularly valproate, carbamazepine and lamotrigine, are human teratogens, while others including topiramate require further investigation. We aimed to appraise the documentation of this risk by psychiatrists and review discussion around contraceptive issues.&lt;/p&gt; &lt;p&gt;Methods: A retrospective review of prescribing patterns of four anticonvulsants (valproate, carbamazepine, lamotrigine and topiramate) in women of child bearing age was undertaken. Documented evidence of discussion surrounding teratogenicity and contraceptive issues was sought.&lt;/p&gt; &lt;p&gt;Results: Valproate was most commonly prescribed (n=67). Evidence of teratogenic risk counselling at medication initiation was sub-optimal – 40% of individuals prescribed carbamazepine and 22% of valproate. Documentation surrounding contraceptive issues was also low- 17% of individuals prescribed carbamazepine and 13% of valproate.&lt;/p&gt; &lt;p&gt;Conclusion: We found both low rates of teratogenic risk counselling and low rates of contraception advice in our cohort. Given the high rates of unplanned pregnancies combined with the relatively high risk of major congenital malformations, it is essential that a detailed appraisal of the risks and benefits associated with anticonvulsant medication occurs and is documented within patients’ psychiatric notes.&lt;/p&gt

Hepatopulmonary hydatidosis in a ten-year-old girl: a case report

<p>Abstract</p> <p>Introduction</p> <p>Hydatid disease is a parasitic infection caused by the tapeworm <it>Echinococcus granulosus </it>and is characterised by cystic lesions in the liver and lungs. Concomitant pulmonary and hepatic localization of hydatid cysts in childhood is unusual and represents a distinct clinical entity called hepatopulmonary hydatidosis.</p> <p>Case presentation</p> <p>A ten-year-old Caucasian girl, a permanent resident of rural Greece, was admitted to hospital reporting a nonspecific symptomatology compatible with a diagnosis of viral infection. Chest radiography revealed a large homogenous circular opacity in the right lung field. On the basis of imaging studies, a diagnosis of hydatidosis was made with synchronous hepatic and pulmonary involvement, successfully managed through a single-stage transthoracic surgical approach.</p> <p>Conclusion</p> <p>This case report highlights the necessity of realizing that hydatid disease continues to be a public health problem, which often remains asymptomatic for years. Therefore, the presence of any homogeneous cystic spherical opacity on routine chest radiography should raise the suspicion of hydatid disease, mainly in endemic areas such as Greece. General practitioners and physicians involved in pediatric care need to be familiar with the diagnosis and management of the variable clinical manifestations of hydatid disease. Taking into consideration that hepatopulmonary hydatidosis represents a special entity that requires a different therapeutic approach may positively affect its economic and social-related burden.</p

Extracorporeal membrane oxygenator as a bridge to successful surgical repair of bronchopleural fistula following bilateral sequential lung transplantation: a case report and review of literature

<p>Abstract</p> <p>Background</p> <p>Lung transplantation (LTx) is widely accepted as a therapeutic option for end-stage respiratory failure in cystic fibrosis. However, airway complications remain a major cause of morbidity and mortality in these patients, serious airway complications like bronchopleural fistula (BPF) are rare, and their management is very difficult.</p> <p>Case presentation</p> <p>A 47-year-old man with end-stage respiratory failure due to cystic fibrosis underwent bilateral sequential lung transplantation. Severe post-operative bleeding occurred due to dense intrapleural adhesions of the native lungs. He was re-explored and packed leading to satisfactory haemostasis. He developed a bronchopleural fistula on the 14^thpost-operative day. The fistula was successfully repaired using pericardial and intercostal vascular flaps with veno-venous extracorporeal membrane oxygenator (VV-ECMO) support. Subsequently his recovery was uneventful.</p> <p>Conclusion</p> <p>The combination of pedicled intercostal and pericardial flaps provide adequate vascular tissue for sealing a large BPF following LTx. Veno-venous ECMO allows a feasible bridge to recovery.</p
