Attenuation of Robust Glial Scar Formation Facilitates Functional Recovery in Animal Models of Chronic Nerve Compression Injury
Authors: Zhu Diana , Tapadia Minal D. , Palispis Winnie , Luu Michele , Wang Weiping , Gupta Ranjan 
Published: December 2017

Background:
Late surgery for chronic nerve compression injuries usually improves sensation but rarely reverses motor atrophy. We hypothesized that a persistent glial scar after chronic nerve compression injury might account for poor motor recovery and that degradation of the glial scar as an adjunct to surgical decompression would improve functional recovery.

Methods:
A previously described model of chronic nerve compression injury was created in C57BL/6 mice and Sprague-Dawley rats, and the nerves were harvested early or late after electrophysiological confirmation of the injury. Western blot, polymerase chain reaction, and quantitative immunohistochemical analyses were performed to determine levels of chondroitin sulfate proteoglycans and extracellular matrix molecules. Subsets of mice were treated either with surgical decompression alone or with decompression coupled with intraepineurial injection of a low dose (0.1 μgμL) or a high dose (0.2 μg/μL) of chondroitinase ABC at 6 weeks after injury.

Results:
Aggrecan showed the greatest change in mRNA and protein levels at the early and late time points following creation of the chronic nerve compression injury. Quantitative immunohistochemical analysis revealed early aggrecan upregulation localized primarily to the endoneurium and late upregulation localized to the perineurium and epineurium (p < 0.0105). Quantitative immunohistochemical analysis for collagen IV, laminin-α2, and fibronectin also showed early upregulation with perineurial scarring. Quantitative immunohistochemical analysis and Western blot analysis for aggrecan demonstrated a marked increase in the endoneurium at the early time points and upregulation of expression in the epineurium and perineurium at the late time points. Decompression along with intraepineurial injection of high-dose chondroitinase ABC at 6 weeks after creation of the compression injury resulted in marked attenuation of decorin and aggrecan expression with functional improvement in nerve conduction velocity.

Conclusions:
Significant upregulation of chondroitin sulfate proteoglycans and other extracellular matrix components contributes to the pathogenesis of compression neuropathies in murine models. The administration of chondroitinase ABC degrades these chondroitin sulfate proteoglycans and improves functional recovery after chronic nerve compression injury; thus, it can be considered as a possible therapeutic adjunct.

<p><em>Diabetes mellitus is one of the generative disease that increase every year. Most cases of diabetes mellitus in Indonesia is type 2, the prevalence 90-95% of all cases of diabetes. About 7% of South Sulawesi's population suffer from this disease. DM is a lifelong disease that requires good management, especially in terms of blood sugar control. The aim of study is to determine factors associated blood sugar level of patients DM type 2 in RSUD Kota Makassar.This study used cross sectional study approach and sample of 149 people. This research was conducted at Internal Polyclinic of RSUD Kota Makassar, data were collected using questionnaires and patient medical records file. The results of univariate analysis showed that most respondents got adequate family support (55.1%). Most people with type 2 diabetes melitus in RSUD Kota Makassar had good diet (51.5%). Blood sugar levels of respondents in this study which were still not well controlled (77.9%). Bivariate analysis with chi square test showed that family support was not related to blood sugar levels (p = 0.26) while diet was associated with blood sugar levels (p = 0,000, = 0.523). That blood sugar levels related with dietary, not family support. <strong>:</strong> It is desirable for health workers to optimize the counseling method for patients, especially in terms of motivating patients to control disease and family should be involved in the counseling activities</em><em>.</em><em></em></p><pre><strong><em> </em></strong></pre><pre><strong><br /></strong><em></em><strong><em></em></strong></pre>

Authors: Benameur Narjes , Arous Younes , Abdallah Nejmeddine ben , Kraiem Tarek 
Published: December 2017

Background:
The assessment of cardiac wall motion abnormalities plays an important
role in the evaluation of many cardiovascular diseases and the prediction of functional recovery.
Most of the methods dedicated to identifying the location of wall motion abnormalities have been
restricted to study hypokinesia while an accurate way to assess dyskinesia is still needed in Cardiac
Magnetic Resonance Imaging (CMRI).
</P><P>
Objective: The aim of this study is to propose a phase image based on the analytic signal able to
assess the extent of the myocardial dyskinetic segments in Cardiac Magnetic Resonance Imaging
(CMRI).
</P><P>
Materials: 22 subjects were retrospectively enrolled in this study (age 46 ± 11): 15 presenting an
aneurysm and 7 control subjects with normal wall motion. For each patient, three standard views
(short axis view, 2 chamber and 4 chamber views) were acquired using 3 Tesla Siemens Avanto
MRI scanner and a segmented True FISP sequence. All the cine MRI images were analyzed by two
experimented observers who were blinded to the diagnostic results.

Results:
The outcomes of this study show that using the proposed phase image in MRI clinical routine
can increase the accuracy of the detection of myocardial dyskinetic segments from 77.23 % to
86.38 %, the sensitivity from 67.48 % to 78.86 % as well the specificity from 80.92 % to 89.23 %
compared to the standard method based on cine MRI interpretation.

Conclusion:
The phase image is a promising tool in CMRI for the assessment of dyskinetic segments
and the degree of myocardial asynchronism.
Shear Strength Prediction of RC Beam-column Sandwich Interior Joints Based on Simplified Softened Strut-and-Tie
Authors: Hou Liqun , Yan Weiming , Chen Shicai , Zhang Ruiyun , Qi Yue 
Published: December 2017

Introduction:
The sandwich joints casted core area with weaker strength concrete of beam, has more advantages than the traditional joints casted core area with higher strength concrete of column, such as the simple construction and quality assurance, while China design codes are too simple about the sandwich joints and have no clear calculation methods.

Methods:
Due to the scarcity of rational models for predicting the strength of RC beam-column sandwich joints, a modified simplified softened strut-and-tie model suggests a more rational calculation method for the effective compressive strength and the height of the joint concrete based on the simplified softened strut-and-tie. The shear strength of existing tested 15 sandwich interior joints is calculated by using the modified simplified softened strut-and-tie model. Furthermore, the theory results are compared with those of the code method and those of the simplified softened strut-and-tie model.

Results and Conclusion:
The results indicate that the code method is more conservative, and the modified simplified softened strut-and-tie can more precisely predict the joint shear strength than that of the softened strut-and-tie model and more secure than that of the code method. Thus, the modified simplified softened strut-and-tie model can reasonable reveal the failure mechanism of RC beam-column sandwich interior joints.

Faktor Penghambat Studi Mahasiswa yang Tidak Lulus Tepat Waktu di Jurusan Pendidikan Teknik Mesin FT UNY
Authors: Widarto Widarto 
Published: December 2017

The study aimed to identify the students who cannot finish their course on time, addressing the inhibiting factor for their course completion, identify the students’ efforts and struggle on their course completion, and to understand their expectations from the school administration to accommodate their course completion. The research used survey methods with questionnaire as the instrument. The subjects of the research are the diploma and bachelor degree students of Mechanical Engineering Education Department. Data were analyzed using quantitative-descriptive technique. The results show that the inhibiting factors are the long commute to campus for supervisions, many students still taking coursework, students already have a job, passive supervisors, unconducive environment, and supervisions that were not intensively done. The students were still committed to complete their course, albeit those inhibiting factors. Students’ commitments were supported by various efforts, namely intensive supervision, independent study or discussion, and finding a conducive environment to work on their final projects and theses. Students’ expectations for the success of their course are the availability of final project and thesis in an earlier stage of their study, supervisor should be appointed based on their competency, increasing the allocated time of the final project schedule, the administration needs to renew the workshop’s machinery and equipment, and cut off the unnecessary final project and Thesis administration steps, to make it easier for students in completing their course. Tujuan penelitian adalah untuk mengidentifikasi mahasiswa yang tidak dapat menyelesaikan studinya tepat waktu, mengetahui faktor penghambat, mengetahui usaha-usaha yang sudah dilakukan mahasiswa, dan mengetahui harapan mahasiswa kepada pengelola Jurusan Pendidikan Teknik Mesin FT UNY. Penelitian menggunakan metode survey menggunakan angket dengan analisis deskriptif kuantitatif. Objek penelitian yaitu mahasiswa D3 Teknik Mesin dan S1 Pendidikan Teknik Mesin. Hasil penelitian menunjukkan terdapat beberapa kendala penyelesaian studi yaitu: jarak yang jauh ke kampus untuk bimbingan, masih ada yang kuliah teori/praktik, sudah ada yang bekerja, dosen kurang aktif membimbing, lingkungan tempat tinggal kurang kondusif, dan bimbingan tidak intensif. Namun demikian, mahasiswa masih berkomitmen untuk menyelesaikan studinya. Keseriusan mahasiswa tersebut didukung dengan berbagai usaha, seperti bimbingan secara intensif, belajar mandiri atau diskusi, dan mencari lingkungan yang kondusif untuk mengerjakan Proyek Akhir dan Skripsi. Selain itu, harapan mahasiswa yaitu mata kuliah Proyek Akhir dan Skripsi dapat diambil lebih awal, penentuan dosen pengampu mata kuliah relevan dengan kompetensinya, jadwal pelaksanaan Proyek Akhir perlu ditambah frekwensinya, peremajakan peralatan bengkel, dan memperpendek administrasi Proyek Akhir dan Skripsi sehingga semakin mempermudah mahasiswa menyelesaikan studinya.

Published: December 2017

Este artigo tem como objetivo descrever o processo de formação, os atuais e os futuros desafios na criação da Liga acadêmica Transdisciplinar de Terapia Intensiva da Universidade Estadual do Sudoeste da Bahia (LITTI – UESB), uma das primeiras ligas transdisciplinares de terapia intensiva no cenário nacional. O projeto tem um caráter extensionista continuado por essência, uma vez que visa a integração dos discentes aos serviços de terapia intensiva da região. Trata-se de um estudo de relato de experiência, contendo a descrição das ações e estratégias para a implantação da LITTI – UESB no campus de Jequié, no ano de 2010, e suas principais ações, integrando o eixo ensino e serviço. A partir do programa de mestrado da Sociedade Brasileira de Terapia Intensiva (SOBRATI), surgiu a vontade do docente Rodrigo Santos Queiroz de fundar uma liga acadêmica na UESB. Diante disso, os discentes Weskley Ramos e Yennydy Moura auxiliaram na formação e criação da LITTI. Dentre as principais realizações extensionistas da liga estão: inserção dos membros na Unidade de Terapia Intensiva (UTI) do Hospital Geral Prado Valadares (HGPV) e realização da estatística descritiva do perfil epidemiológico dessa instituição; aprovação de um membro, em primeiro lugar, no programa de residência em Fisioterapia Pneumofuncional do Estado da Bahia (2011) e mais três aprovações na residência da Incor em São Paulo; realização de palestras sobre quatro grandes temas em terapia intensiva; promoção dos discentes em congressos. Como proposta futura, está sendo organizado um projeto de intervenção para a melhoria da qualidade de assistência da UTI do HGPV. A LITTI é uma ideia inovadora no cenário nacional, promissora no seu caráter transdisciplinar e extracurricular, que garante aos discentes um raciocínio construtivo, teórico e prático sobre os tópicos relacionados à área de terapia intensiva e estimula a formação de novas ligas nas faculdades e universidades brasileiras.
