Character recognition in a document image captured by a digital camera requires a good binary image as the input for the separation the text from the background. Global binarization method does not provide such good separation because of the problem of uneven levels of lighting in images captured by cameras. Local binarization method overcomes the problem but requires a method to partition the large image into local windows properly. In this paper, we propose a local binariation method with dynamic image partitioning using integral image and decision tree for the binarization decision. The integral image is used to estimate the number of line in the document image. The number of line in the document image is used to devide the document into local windows. The decision tree makes a decision for threshold in every local window. The result shows that the proposed method can separate the text from the background better than using global thresholding with the best OCR result of the binarized image is 99.4%. Pengenalan karakter pada sebuah dokumen citra yang diambil menggunakan kamera digital membutuhkan citra yang terbinerisasi dengan baik untuk memisahkan antara teks dengan background. Metode binarisasi global tidak memberikan hasil pemisahan yang bagus karena permasalahan tingkat pencahayaan yang tidak seimbang pada citra hasil kamera digital. Metode binarisasi lokal dapat mengatasi permasalahan tersebut namun metode tersebut membutuhkan metode untuk membagi citra ke dalam bagian-bagian window lokal. Pada paper ini diusulkan sebuah metode binarisasi lokal dengan pembagian citra secara dinamis menggunakan integral image dan decision tree untuk keputusan binarisasi lokalnya. Integral image digunakan untuk mengestimasi jumlah baris teks dalam dokumen citra. Jumlah baris tersebut kemudian digunakan untuk membagi citra dokumen ke dalam window lokal. Keputusan nilai threshold untuk setiap window lokal ditentukan dengan decisiontree. Hasilnya menunjukkan metode yang diusulkan dapat memisahkan teks dari dokumen citra lebih baik dari binarisasi global dengan tingkat pengenalan OCR hingga 99.4%.

Black hole attack is an attack where a node that responds to RREQ from the source node by replying a fake freshness information and false hop count. The black hole nodes do not respond to distributed co-operation in routing protocol to absorb all the packets, as a result, the network performance will drop. Most previous works are focused on anomaly detection through dynamic trusted of the neighbouring nodes. We find out that the internal comparisons take a long time. This loss can be shortened by changing the routing mechanism. We propose an enhancement of AODV protocol, named EAODV, that is able to prevent black hole attacks. The EAODV can find a shortest path of routing discovery using A* heuristic search algorithm. Values of hop count and estimate time to reach the destination node are used as input in the heuristic equation and one-way hash function is used to make a secure value and then to casting it to all neighbouring nodes. Experiments were conducted in NS2 to simulate EAODV in different running time with and without black hole nodes. The EAODV performance results are indicated better in terms Packet loss and Average End-to-End delay.

Abstract Malocclusion is a clinical symptom, in which the teeth of maxilla and mandible are not located at the proper location. If malocclusion left untreated, it can lead to complications in the digestive system, headache, and periodontal disease disorders. Malocclusion problems involving abnormalities of teeth, bones, and muscles around the jaw are obligation of orthodontic specialists to treat them. The treatments can be varying based on the type of malocclusion, including tooth extraction and tooth braces. To know certain degree of malocclusion experienced by the patient, an assessment method called Peer Assessment Rating (PAR) Index is usually used by the specialist. To help the works of orthodontic specialists in Indonesia, a new automated calculation system based on 2D image of tooth model for PAR Index is being developed. In this paper, the calculation system for over-jet, open-bite, and teeth segmentation is developed. The result of the developed system is then compared with manual assessment done by orthodontic specialist, in order to verify the accuracy of the system.

Abstract

Macular edema is a kind of human sight disease as a result of advanced stage of diabetic retinopathy. It affects the central vision of patients and in severe cases lead to blindness. However, it is still difficult to diagnose the grade of macular edema quickly and accurately even by the medical doctor's skill. This paper proposes a new method to classify fundus images of diabetics by combining Self-Organizing Maps (SOM) and Generalized Vector Quantization (GLVQ) that will produce optimal weight in grading macular edema disease class. The proposed method consists of two learning phases. In the first phase, SOM is used to obtain the optimal weight based on dataset and random weight input. The second phase, GLVQ is used as main method to train data based on optimal weight gained from SOM. Final weights from GLVQ are used in fundus image classification. Experimental result shows that the proposed method is good for classification, with accuracy, sensitivity, and specificity at 80%, 100%, and 60%, respectively.

Abstract

Image segmentation is typically used to distinguish objects that exist in an image. However, it remains difficult to accommodate favourable thresholding in multimodal image histogram problem with specifically desired number of thresholds. This research proposes a novel approach to find thresholds in multimodal grayscale image histogram. This method consists of histogram smoothing, identification of peak(s) and valley(s), and merging process using hierarchical cluster analysis. Using five images that consisted of grayscale and converted-to-grayscale images. This method yields maximum value of accuracy, precision, and recall of 99.93%, 99.75%, and 99.75% respectively. These results are better than the similar peak finding method in multimodal grayscale image segmentation.

Ant-based document clustering is a cluster method of measuring text documents similarity based on the shortest path between nodes (trial phase) and determines the optimal clusters of sequence document similarity (dividing phase). The processing time of trial phase Ant algorithms to make document vectors is very long because of high dimensional Document-Term Matrix (DTM). In this paper, we proposed a document clustering method for optimizing dimension reduction using Singular Value Decomposition-Principal Component Analysis (SVDPCA) and Ant algorithms. SVDPCA reduces size of the DTM dimensions by converting freq-term of conventional DTM to score-pc of Document-PC Matrix (DPCM). Ant algorithms creates documents clustering using the vector space model based on the dimension reduction result of DPCM. The experimental results on 506 news documents in Indonesian language demonstrated that the proposed method worked well to optimize dimension reduction up to 99.7%. We could speed up execution time efficiently of the trial phase and maintain the best F-measure achieved from experiments was 0.88 (88%).

Neural network attracts plenty of researchers lately. Substantial number of renowned universities have developed neural network for various both academically and industrially applications. Neural network shows considerable performance on various purposes. Nevertheless, for complex applications, neural network’s accuracy significantly deteriorates. To tackle the aforementioned drawback, lot of researches had been undertaken on the improvement of the standard neural network. One of the most promising modifications on standard neural network for complex applications is deep learning method. In this paper, we proposed the utilization of Particle Swarm Optimization (PSO) in Convolutional Neural Networks (CNNs), which is one of the basic methods in deep learning. The use of PSO on the training process aims to optimize the results of the solution vectors on CNN in order to improve the recognition accuracy. The data used in this research is handwritten digit from MNIST. The experiments exhibited that the accuracy can be attained in 4 epoch is 95.08%. This result was better than the conventional CNN and DBN.  The execution time was also almost similar to the conventional CNN. Therefore, the proposed method was a promising method.

Makalah ini membahas dua pilihan penerapan struktur basis data citra pada sistem pencarian citra berbasis isi. Pendekatan pertama menggunakan folder untuk menyimpan berkas citra dan Java object serialization untuk menyimpan data citra. Pendekatan kedua menggunakan basis data Data Base Management System MySQL untuk menyimpan berkas dan data citra. Kedua pendekatan dibahas dari aspek penerapan struktur basis data untuk tujuan pengembangan sistem pencarian citra berbasis isi yang efisien. Data yang tidak terstruktur dan proses clustering data lebih mudah ditangani dengan struktur basis data dari pendekatan pertama. Data yang jumlahnya besar dan terstruktur serta proses indexing lebih mudah ditangani dengan struktur basis data dari pendekatan kedua. Sistem pencarian citra berbasis isi lebih banyak melakukan kueri jenis select dibandingkan dengan insert dan update data, dalam hal ini kedua pendekatan dapat memenuhinya dengan baik. Secara umum, pendekatan kedua dianggap memberikan dukungan yang baik dalam penyimpanan dan manipulasi data, serta dapat mengurangi upaya dan waktu yang dibutuhkan pada pengembangan sistem.

Published: July 2016

Paradigma Baru Pendidikan Tinggi [1,2] yang dicanangkan oleh Direktorat Jenderal Pendidikan Tinggi pada tahun 1995, mengubah pola manajemen institusi pendidikan tinggi di Indonesia, dimana manajemen institusi pendidikan tinggi harus senantiasa melakukan evaluasi diri secara berkesinambungan guna peningkatan kualitas institusi tersebut dalam melaksanakan misi Tridharma Pendidikan Tinggi. Untuk dapat melakukan evaluasi diri diperlukan berbagai data dan informasi, baik data internal maupun eksternal institusi. Dengan melihat kebutuhan berbagai macam data dan informasi yang diperlukan untuk penyusunan laporan evaluasi diri, seharusnya dapat mendorong pemanfaatan teknologi data warehouse maupun data mining pada institusi tersebut. Pada kenyataannya, belum ada satupun institusi pendidikan tinggi di Indonesia yang memanfaatkan teknologi data warehouse maupun data mining untuk penyusunan laporan evaluasi diri. Hal ini disebabkan karena hampir semua institusi pendidikan tinggi di Indonesia belum mempunyai Sistem Informasi yang tertata dengan baik dan digunakan untuk pengelolaan manajemen institusi pendidikan tinggi pada semua jenjang atau tingkatan manajemen (institusi, fakultas, jurusan maupun program studi).

Tulisan ini mengusulkan suatu metode untuk merancang struktur fungsi dan peran tata kelola data suatu organisasi. Metode ini berorientasi pada permasalahan, yaitu menyusun rancangan struktur berangkat dari permasalahan yang dihadapi organisasi dan memperhatikan unit-unit kerja organisasi yang ada saat ini. Tulisan ini menguraikan penerapan metode ini dalam merancang kerangka kerja tata kelola data untuk meningkatkan dan menjaga kualitas data suatu organisasi. Dari permasalahan kualitas data yang dihadapi, diidentifikasi artifak tata kelola – seperti ketentuan, standar, arsitektur – yang dibutuhkan untuk mengendalikan permasalahan-permasalahan tersebut; diidentifikasi aktivitas-aktivitas yang dibutuhkan untuk menghasilkan dan mengelola artifak tersebut; diidentifikasi peran dan fungsi yang terlibat dalam aktivitas-aktivitas tersebut; dan akhirnya menata peran-peran tersebut dalam suatu struktur organisasi. Tulisan ini menunjukkan bahwa struktur yang dihasilkan setara dengan struktur yang disusun berdasarkan kerangka-kerangka kerja teoritis, dengan kelebihan adanya spesifikasi tentang siapa yang layak memegang peran dalam struktur tersebut dan apa tanggung jawabnya. This paper proposes a method for designing the function structure and of the role of an organization's data governance. The method is oriented to the problem, by arranging the structure of a draft set of issues faced by the organization and showing to organizational work units that exist today. This paper describes the application of this method in designing a data governance framework to improve and maintain the quality of organization's data. From data quality problems, we identified governance artifacts - such as regulations, standards, architecture – that is needed to control these problems; identified the activities required to generate and manage these artifacts; identified the roles and functions involved in activities these, and finally organize these roles in an organizational structure. This paper shows that the resulting structure is equivalent to a structure based on theoretical frameworks, with an excess of the specification of who should play a role in the structure and what are the responsibilities.

Sistem penagihan memegang peranan penting dalam rumah sakit karena menentukan ketahanan keuangan rumah sakit. Kompleksitas rumah sakit menimbulkan sistem penagihan yang juga kompleks sehingga diperlukan pembelajaran dan kajian mendalam mengenai sistem penagihan terkait dengan fungsi-fungsi dasar dalam rumah sakit. Perkembangan sistem penagihan baru yang dirintis Kementerian Kesehatan Republik Indonesia yang berbasis Diagnosis memberi tekanan bagi rumah sakit untuk membenahi sistem penagihannya dan fungsi-fungsi terkait, di antaranya manajemen barang medis dan non medis dalam rumah sakit. Alasan klasik “demi kepentingan pengobatan pasien” akan menjadi bumerang bagi rumah sakit karena pembengkakan biaya perawatan. Rumah sakit tidak dapat lagi memberikan tagihan besar untuk bahan habis pakai bagi pasien ketika penagihan berbasis diagnosis wajib digunakan oleh rumah sakit.

Authors: Temizturk Zeki , Azboy Davut , Atalay Atakan , Atalay Hakan , Dogan Omer Faruk
Published: July 2016

Objective:

The aim of our study was to research the effects of levosimendan (LS) and sodium nitroprusside (SNP) combination on systolic and diastolic ventricular function after coronary artery bypass grafting (CABG) who required endoventricular patch repair (EVPR).

Patients and Methods:

We studied 70 patients with ischemic dilated cardiomyopathy. LS and SNP combination was administered in 35 patients (study group, SG). In the remaining patients, normal saline solution was given (placebo group, PG). Levosimendan (10µgr/kg) started 4 h prior to operation and we stopped LS before the initiation of extracorporeal circulation (ECC). During the rewarming period, we started again levosimendan (10µgr/kg) in combination with SNP (0.1-0.2 µgr/kg/min). If mean blood pressure decreased by more than 25% compared with pre-infusion values, for corrected of mean arterial pressure, the volume loading was performed using a 500 ml ringer lactate. Hemodynamic variables, inotrophyc requirement, and laboratory values were recorded.

Results:

Five patients died (7.14%) post-surgery (one from SG and 4 from PG) due to low cardiac out-put syndrome (LOS). At the postoperative period, cardiac output and stroke volume index was higher in SG (mean±sd;29.1±6.3vs. 18.4±4.9 mL/min−1/m−2(P<0.0001)). Stroke volume index (SVI) decreased from 29±10mL/m2preoperatively to 22±14mL/m2in the early postoperative period in group 1. This difference was statistically significant(P=0.002). Cardiac index was higher in SG (320.7±37.5vs. 283.0±83.9 mL/min−1/m−2(P=0.009)). The postoperative inotrophyc requirement was less in SG (5.6±2.7vs. 10.4±2.0 mg/kg,P< 0.008), and postoperative cardiac enzyme levels were less in SG (P< 0.01). Ten patients (28.5%) in SG and 21 patients (60%) in PG required inotrophyc support(P<0.001). We used IABP in eight patients (22.8%) in SG and 17 patients (48.5%) in CG(P=0.0001).

Conclusion:

This study showed that LS and SNP combination impressive increase in left ventricular systolic and diastolic functions including LVEF. The use of this combination achieved more less inotrophics and IABP requirement. We therefore suggest preoperative and peroperative levosimendan and SNP combination.

Authors: Ran Caroline , Mehdi Rawand Naiel , Fardell Camilla , Xiang Fengqing , Nissbrandt Hans , Sydow Olof , Wirdefeldt Karin , Belin Andrea Carmine
Published: July 2016

Background:

Integrin alpha 8 (ITGA8) encodes the alpha 8 subunit of the integrin alpha8beta1 protein and has recently been suggested as a new candidate gene for Parkinson’s disease, an age related neurodegenerative disease with unknown etiology. ITGA8 is a transmembrane protein involved in several cellular processes, such as cell adhesion, migration and cytoskeletal rearrangement.

Objective:

Screen a Swedish case control material for rs7077361, a genetic variant in ITGA8, in order to investigate its possible implication in Parkinson’s disease in Sweden.

Method:

Rs7077361 was genotyped using TaqMan quantitative Real-time PCR and tested for association using appropriate statistical methods.

Results:

We have screened 502 Swedish Parkinson patients and 599 healthy control individuals for rs7077361 in ITGA8. This genetic variant was in Hardy Weinberg equilibrium in the Swedish population. Allele and genotype frequencies were highly similar between the patients and controls and statistical testing showed that this genetic maker did not associate with Parkinson’s disease (p=0.67).

Conclusion:

Our results do not support the hypothesis of ITGA8 as a candidate gene for Parkinson’s disease in Sweden.
Potential of criminological research in evaluation of victim-focused policy and legislation in the Czech Republic
Authors: Stefunková Michaela
Published: July 2016

For effective victim-focused legislation, evidence-based knowledge is
essential, thus making criminological research of great importance.
Victimization surveys represent a globally recognized type of criminological
investigation. Although they are primarily focused on measuring the dark
figure of crime, they can also provide a broad spectrum of information on
victimization-related issues. The latest victimization survey was carried out
in the Czech Republic by the Institute of Criminology and Social Prevention
in 2013. Through face to face interviews, victimization was explored through
eight selected offences in the period of 12 months prior the survey. The
representative sample included 3000 respondents 15 years of age and older.
The next round is planned for 2017. Since 2013, a new Act no. 45/2013 Coll.,
on Victims of Crime has come into effect in the Czech Republic. This paper
will discuss how victimization surveys can enrich the knowledge on
victimization-related issues and how they can help in the evaluation of
criminal policy.
Media coverage of violence against women in the family and in an intimate partner relationship in Serbia
Authors: Resimic Milos
Published: July 2016

This article examines the media coverage of violence against women in the
family and in an intimate partner relationship in Serbia. The goal of this
article is to point to the potential that implementing the relevant state
policies might have on the quality of the media coverage, by analysing the
effects of state policies on the media coverage of violence against women in
the family and in an intimate partner relationship. This study utilizes
quantitative content analysis and qualitative framing analysis on a sample of
330 articles of Serbian daily newspapers Blic, Kurir and Politika in two time
periods (three months in 2006 and three months in 2013). The results of the
quantitative content analysis show a significant increase in the number of
articles containing information on statistics, services for victims and
expert sources. Qualitative framing analysis points to the conclusion that
the nature of the media frame has not meaningfully changed. Namely, under the
pressure of editors, journalists continue with framing violence against women
in a stereotyped fashion which reflects the suppressed position of women in
the Serbian society.
Factors that affect therapeutic efficacy and safety of drugs

Published: July 2016

According to the Law on medicines and medicinal devices, veterinary drugs
must be of high quality, efficacy and safety to be suitable for use on
animals. However, there are numerous factors which can alter the intensity of
drugs and their established therapeutic efficacy and safety. These factors
may depend on the patients themselves i.e. animals (species, age, sex,
physiological state, impaired functions of organs involved in the elimination
of drugs, diseases of other organ systems, nutrition, genetic disorders,
individual variations, tolerance etc.), veterinary surgeons (use of the drug
which is not in accordance with the instructions - ?off-label use?, improper
selection of a drug or drug combination intended for a certain animal species
or pathological condition, inadequate drug administration route, inadequate
drug dosage and duration of therapy) and the drug itself (inappropriate
formulation, bioavailability, instability of formulation, diminishing drug
action due to external factors). Not following the instructions on using a
drug and incorrect application may affect the rate and extent of the drug
absorption. The route of the administration of a pharmaceutical product is
defined in clinical trials, and depends on the physical and chemical
properties of the active ingredient, characteristics of the pharmaceutical
formulation and the anatomical and physiological characteristics of
application sites which enable absorption. An adequate drug administration
ensures a predictable level and rate of absorption from the application site,
drug concentration at the sites of its action and pharmacological response or
therapeutic efficacy. Concomitant use of multiple drugs in the same patient
should be avoided because of possible interactions (antagonism or sinergism)
which may decrease the activity of a drug and its effectiveness or increase
them including appearance of drug toxicity. In addition, mixing drugs in an
infusion system or a syringe should be avoided because the absence of visible
interaction does not mean that the drugs applied are compatible.

Background/Aim. Denture stomatitis (DS) is one of the most common oral health problems among elderly population with removable dentures. Despite the high prevalence, etiology of the disease is not completely understood. It appears to be multifactorial, with a predominance of local factors. The aim of the study was to determine the prevalence and risk factors that contribute to the development of DS in upper removable denture wearers. Methods. This clinical study comprised three groups of subjects with upper removable dentures: the DS group, and the positive and negative control groups. Swab samples were taken from the tongue and palatal mucosa for microbiological examination. Data of denture age, dentures night wearing, unstimulated salivary flow rate (USFR) and saliva pH values were evaluated for all the participants. Results. The prevalence of DS was found to be 26.5%. Significantly higher values of overnight wearing (p = 0.000) and the mean age of dentures (p = 0.022) were found in the DS group compared to the controls. In relation to the positive mycological finding, a borderline significance difference among the groups was confirmed (p = 0.053). No significant association was found between DS and gender, age, the type of dentures, USFR, pH of saliva and bacteria findings. The patients who wore dentures at night had 26 times more chances to get DS compared to the patients who did not wear them overnight. Conclusion. This study confirms similar characteristics of DS prevalence in elderly population of Vojvodina compared to European. Continuous (overnight) wearing of dentures is considered to be major direct risk factor for DS development, while secondary role is attributed to denture age and oral Candida infection.

Background/Aim. In the last two decades there has been a significant progress in rectal cancer surgery. Preoperative radiotherapy, the introduction of staplers and largely improved surgical techniques have greatly contributed to better treatment outcomes, primarily by reducing the frequency of early surgical complications and the rate of local recurrence. The aim of this study was to compare operative and postoperative results in the treatment of rectal cancer between the two groups of surgeons ? those who are closely engaged in colorectal surgery and those who deal with these issues sporadically. Methods. This retrospective study included 146 patients who had underwent rectal cancer surgery at the Institute of Oncology of Vojvodina in the period from January 1, 2008 to December 31, 2010. The patients were divided into two groups, the group N1 of 101 patients operated on by trained colorectal surgeons, and the group N2 of 45 patients operated on by surgeons without training in totalmesorectal excision (TME). Results. Preoperative chemoradiotherapy was received by 49 (33.56%) of the patients. A statistically significant difference between the two groups was noted in the duration of surgery and the need for blood transfusion during surgery. Anastomotic leakage occurred in 3 patients from the group N1 and in 10 patients from the group N2. Seven (4.79%) of the patients developed local recurrence after surgical treatment. There were significant differences in local recurrence rate and anastomotic leakage rate between the compared groups. Conclusion. It is necessary to continue education and training in surgery for rectal cancer to master new technologies and surgical techniques and to improve the results of surgical treatment.

Published: July 2016

Background/Aim. Chronic hepatitis C and liver steatosis often appear simultaneously in the same person, and steatosis can lead to worsening of liver disease and reducing the success of the treatment of chronic hepatitis C. Treatment of one disease can influence and cause favorable impact on treatment of other diseases. The aim of this study was to determine the incidence of liver steatosis in patients with chronic hepatitis C and to examine the impact of steatosis of the liver and other predictors on the success of antiviral therapy for chronic hepatitis C. Methods. The study included 123 patients with chronic hepatitis C treated with pegylated interferon alfa 2a in combination with ribavirin. The patients were divided into two groups based on the presence of cirrhosis: the group I consisted of 43 (34.9%) patients with steatosis and the group II consisted of 80 (65.1%) patients without liver steatosis. The success of the treatment was evaluated on the basis of the stable virological response. Results. The presence of steatosis was determined in 34.96% of the patients. The overall success of antiviral therapy was found in 74.79% of the patients. The success of antiviral therapy was present in 62.79% of the patients with hepatic steatosis, and in 81.25% the patients without steatosis (p < 0.05). The success of antiviral treatments was seen in 80.95% of the patients with hepatic steatosis and the genotype of hepatitis C virus 3. The predictors of antiviral therapy success for chronic hepatitis C in our study were patient's age, duration of infection, genotype 3, steatosis and severe fibrosis or cirrhosis. Conclusion. Liver steatosis is often present in patients with chronic hepatitis C. It has negative impact on the efficacy of antiviral therapy in patients with infection with genotype non-3 hepatitis C virus. Therefore, hepatic steatosis in these patients must be eliminated or treated prior to application of antiviral therapy.
The Impact of the Timing of a Prior Year's Auditor Concessions on Financial Officers' Judgments

Published: July 2016

Auditors and clients negotiate on financial statement numbers over time. In this study, we extend the existing literature on auditor-client negotiations by examining the judgments of client financial officers in a multi-period setting. We conduct an experiment to examine how an auditor's use of concession-timing strategies in the prior year influences financial officers' negotiation judgments in the current year. We find that financial officers report a larger expected ultimate income-decreasing audit adjustment and are prepared to offer more concessions if the auditor had previously used a concession-start strategy (where the auditor had given a concession before the start of the negotiation but did not concede during the negotiation) relative to a concession-end strategy (where the concession was provided only in the last round of negotiation). Our results indicate that auditors' prior negotiation strategies impact financial officers' use of strategies on current year's negotiations. Overall, these results suggest that findings in earlier single-period settings (e.g., Tan and Trotman 2010) potentially reverse in a multi-period setting.
Lack of miR-133a Decreases Contractility of Diabetic Hearts: A Role for Novel Cross Talk Between Tyrosine Aminotransferase and Tyrosine Hydroxylase

MicroRNAs (miRNAs) have a fundamental role in diabetic heart failure. The cardioprotective miRNA-133a (miR-133a) is downregulated, and contractility is decreased in diabetic hearts. Norepinephrine (NE) is a key catecholamine that stimulates contractility by activating β-adrenergic receptors (β-AR). NE is synthesized from tyrosine by the rate-limiting enzyme, tyrosine hydroxylase (TH), and tyrosine is catabolized by tyrosine aminotransferase (TAT). However, the cross talk/link between TAT and TH in the heart is unclear. To determine whether miR-133a plays a role in the cross talk between TH and TAT and regulates contractility by influencing NE biosynthesis and/or β-AR levels in diabetic hearts, Sprague-Dawley rats and miR-133a transgenic (miR-133aTg) mice were injected with streptozotocin to induce diabetes. The diabetic rats were then treated with miR-133a mimic or scrambled miRNA. Our results revealed that miR-133a mimic treatment improved the contractility of the diabetic rat’s heart concomitant with upregulation of TH, cardiac NE, β-AR, and downregulation of TAT and plasma levels of NE. In miR-133aTg mice, cardiac-specific miR-133a overexpression prevented upregulation of TAT and suppression of TH in the heart after streptozotocin was administered. Moreover, miR-133a overexpression in CATH.a neuronal cells suppressed TAT with concomitant upregulation of TH, whereas knockdown and overexpression of TAT demonstrated that TAT inhibited TH. Luciferase reporter assay confirmed that miR-133a targets TAT. In conclusion, miR-133a controls the contractility of diabetic hearts by targeting TAT, regulating NE biosynthesis, and consequently, β-AR and cardiac function.
