Background-AIMS: Little is known about the prognostic significance of elevated serum relaxin in acute myocardial infarction (AMI) patients.The present study is designed to investigate the potential association between serum relaxin levels and the risk of AMI. MATERIALS AND METHODS:We measured circulating relaxin levels in 80 patients (median age 62.3 years) who presented with first-time AMI 8 hours after the incident.The circulating relaxin-2 levels in 80 healthy volunteers (median age 61.5 years) was also measured. Relaxin-2 was detected using enzyme immunoassay in both groups. RESULTS: Serum relaxin levels were significantly higher in patients with AMI (27.4±6.3ng/ml) compared to controls (9.2±2.3 ng/ml)(P<0.01).We found that a relaxin level>13.8 ng/ml had a sensitivity of 79% and a specificity of 86% for predicting AMI.Relaxin revealed the higher sensitivity and specificity for diagnosing AMI. CONCLUSIONS: Elevated Relaxin in plasma may be a novel biomarker for early detection of AMI

Objective\nThe purpose of this study was to assess the efficacy and outcomes of preoperative prophylactic metoclopramide and dimenhydrinate use in elective cesarean births.\nMaterial and Methods\nParticipants (n=84) scheduled for elective cesarean births were randomized equally into placebo (10cc 0.9% NaCl), 10mg metoclopramide or 50 mg dimenhydrinate groups. \nOral alimentation was prohibited eight hours before the surgery; however patients continued drinking water until four hours before surgery. Placebo and anti-emetics were administered 1 hour before the anticipated procedure in a 5 ml syringe. In metoclopramide and dimenhydrinate group an ampoule of the agents were completed to 5 ml by adding 0.9% NaCl. In the control group 5 ml of 0.9% NaCl was used. All prophylactic agents were administered intramuscularly. All patients received a general anesthesia.\nThe placebo group (control group) was compared with the metoclopramide and dimenhydrinate groups.\nResults\nDemographic data including maternal age, height, weight, body mass index, gravidity, parity, miscarriage, induced abortion, the number of offspring, and the medical history did not show significant differences among the three groups.\nPostoperative nausea, vomiting and the use of rescue medication ratios were significantly lower in metoclopramide and dimenhydrinate groups compared with the placebo group (p<0.05), however the difference between the metoclopramide and dimenhydrinate groups was not significant (p>0.05).\nConclusions\nDimenhydrinate and metoclopramide significantly decrease postoperative nausea, vomiting and the need for rescue anti emetic medication. Both agents have similar efficacy and may be used as an alternative to each other.

Recent developments in Cardiac surgery have led to increase in number of patients between the age group of 25 and 69 years of age who have survived Myocardial Infarction. Regular and continuous monitoring of these patients becomes essential as this age group of people is the real asset to a family. Hence this paper aims in design and development of low cost, light weight, portable Telecardiac system for remote monitoring of cardiac patients. The proposed system employs a Field Programmable Gate Array(FPGA), a reconfigurable platform that performs online analysis of the acquired ECG signal continuously . FPGA based Arrhythmia detector, implemented on a DE2 Altera Cyclone II board is interfaced with GSM/GPS module to alert the physician on a mobile phone about the imminent fatal condition and location of the patient. If the portable system detects any arrhythmia, it automatically sends an alarm condition to the patient’s care taker and ambulance centre by sending an SMS that has information about the abnormal condition and location of the patient.

Providing security and efficient access control for video streaming in cloud computing is one of the challenging ongoing research works ,because the data owners outsource their multimedia data to the cloud service provider to make it available for the user at anytime , anywhere and by using any devices. Existing solutions for secure video streaming uses standard cryptographic techniques. But it suffers from heavy computational cost, both in the data owner and in the user sides. For example if we use AES for encryption and decryption for large video files, the processing time in terms of encryption and decryption will increase even though it provides higher level of security. Also AES kind of security is not needed for simple media files and e-learning type of applications. This paper addresses this challenging problem by proposing MBBXOR Encryption Algorithm – a computational efficient encryp-tion/decryption algorithm for multimedia streaming in cloud computing. The simulation runs and analysis shows that the proposed approach is highly efficient and provides adequate security.

While the use of Communicative Language Teaching (CLT) has been adopted in different contexts all over the world and many textbook designers and also administrative executives recommend this approach to the teachers. Different researches show that teachers can rarely apply CLT perfectly in different secondary schools especially in non-native classroom contexts. Education reformations in Malaysia assigned different teachers to apply learner-centered environment for the students, but in most of the cases instructional practices remained the same according to traditional teacher-centered eastern contexts where teachers have the dominant role in the classroom context. CLT has been received a significant attention as an offspring leaner-centered approach and it has been emphasized to apply in the Malaysia. In this study researchers attempted to evaluate implementation of CLT in the Malaysian secondary schools through several observations. Observations have been implemented by using an observation scheme based on CLT principles. 30 secondary school classes in the Johor district, Malaysia have been observed. During the observations researchers found that in the CLT classes, teachers had several problems to apply CLT in the Malaysian secondary schools such as the culture of Malaysia, in which teachers have the dominant role and also students’ proficiency in English which has been considered as the prerequisite of CLT implementation in educational contexts. Hopefully results of the current study, seems to be useful for several people who can benefit from the results like students and teachers as the main role makers of CLT implementation in Malaysia and also administrative executives in the ministry of education of this country to know the CLT implementation challenges in the Malaysian contexts.
