Jaffry Zakaria, Mazuki Mohd Yasim, Md Amin Md Taff, Benderi Dasril, Mirza Azny Mustafa
Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103168
White water kayaking is the fun sport on fast moving water, typically call white water river. The element of fun and challenge has attracted many people to join this adventure sports in Malaysia. This study examined the risk in adventure sport tourism by white water kayakers in Malaysia. The objective of this study is to reveal the injuries suffered by whitewater kayakers during activity. This 2013 survey will be described using descriptive data only. The survey forms were distributed via kayak clubs and associations under the auspices of the Malaysian Canoe Association (MASCA). The survey asked respondents about their previous injuries during white water kayaking activities. All the data concerning to age, sex, experience and ability was collected from them. A total of 217 respondents provided feedback on this survey. Of the total 217, about 186 respondents experienced injuries during an activity, while the rest did not suffer any injuries while they were kayaking. The result showed only 41% seeks medical attention after injury. These whitewater kayaking activities require physical exertion as well as emotional and mental stability. Good practise and skill can help kayakers avoid injuries and accident during paddling session. This sport has been developing and growing each year. Future studies can also be done by looking for new discipline in white water which is “playboating” which may find different risk and injury.
Co-Conserved Features Associated with cis Regulation of ErbB Tyrosine Kinases
Amar Mirza,Morad Mustafa,Eric Talevich,Natarajan Kannan
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0014310
Abstract: The epidermal growth factor receptor kinases, or ErbB kinases, belong to a large sub-group of receptor tyrosine kinases (RTKs), which share a conserved catalytic core. The catalytic core of ErbB kinases have functionally diverged from other RTKs in that they are activated by a unique allosteric mechanism that involves specific interactions between the kinase core and the flanking Juxtamembrane (JM) and COOH-terminal tail (C-terminal tail). Although extensive studies on ErbB and related tyrosine kinases have provided important insights into the structural basis for ErbB kinase functional divergence, the sequence features that contribute to the unique regulation of ErbB kinases have not been systematically explored.

“Kurdistan” Technique for the Treatment of Unprotected Trifurcation Left Main Stem Coronary Artery Lesion: Case Report  [PDF]
Aram J. Mirza
World Journal of Cardiovascular Diseases (WJCD) , 2014, DOI: 10.4236/wjcd.2014.49058

The left main coronary artery (LMCA) is responsible for supplying about 75% to 100% of the left ventricular cardiac mass. Left main stem coronary artery (LMCA) disease reduces flow to a large portion of the myocardium, placing the patient at high risk for life-threatening events such as left ventricular dysfunction and arrhythmias with a high mortality approaching 50% in those treated medically. For several decades, coronary artery bypass grafting (CABG) has been considered as a gold standard treatment of unprotected left main coronary artery (ULMCA). However, successful percutaneous coronary interventions (PCI) have been increasingly reported recently due to improved stent technology and better operator expertise. In spite of these factors, management can be challenging especially in LMCA bifurcational & trifurcational lesions, and therefore an integrated approach combining special techniques, physiological evaluation and adjunctive pharmacological agents should be combined for better clinical outcome. Herein, we describe a new promising technique named (Kurdistan technique) for the treatment of trifurcation unprotected left main stem lesion. In the last 18 months, 21 patients with significant trifurcational LMS had underwent PCI using this technique in our hospital (Sulaimany Heart Hospital/Kurdistan). The procedural success rate was 100%, follow up coronary angiography done between 6 - 12 months after the procedure for all the patients with no significant in-stent restenosis in any patient. One case is presented here demonstrating the technique.

Abstract: Background: Few data on the clinical course and management of patients experiencing restenosis after implantation of long drug-eluting stents treatment for coronary arteries was available. Objectives: The aim of this study was to evaluate the incidence, predictors, and long-term outcomes of patients with in-stent restenosis (ISR) after percutaneous coronary intervention (PCI) with long (33 mm & 38 mm) drug-eluting stents (DES) for long lesions in coronary arteries including left anterior descending artery (LAD), Lt circumflex artery (Lt Cx), right coronary artery (RCA), obtuse marginal artery (OM) & posterior descending artery (PDA). Methods: Between July 2009 and October 2010, 421 long DES had being implanted in 421 consecutive patients with significant coronary artery stenosis, with 371 patients (88%) undergoing routine follow up, clinical follow up done by exercise stress test at 6 & 12 months after stenting for 126 patients (34%), in 124 patients (33.5%) follow up was done by Computed Tomography angiography & 121 patients (32.5%) with clinically driven angiographic follow-up. A major adverse cardiac event was defined as the composite of death, myocardial infarction (MI), or target-lesion revascularization (TLR) within 15 months. Results: All patients who underwent clinical follow up were asymptomatic. The overall incidence of angiographic (CT or conventional) ISR with long (33 mm & 38 mm) DES was 4% (15 out of 371 stents) with 8 (53.3%) focal-type and 7 (46.7%) with diffuse-type ISR. Six patients (40%) under-went repeated PCI, seven (46.7%) underwent bypass surgery, and 2 (13.3%) were treated medically. During long-term follow-up (ranging from 12 - 26 months), there were no deaths, 3 (0.8%) MI, and 13 (3.5%) repeated target-lesion revascularization (PCI or CABG) cases. The incidence of major adverse cardiac event was 5.3% in the medical group, 10.1% in the repeated PCI group, and 21.4% in the bypass surgery group. Multivariate analysis showed that the occurrence of DES-ISR did not affect the risk of death or MI. Conclusions: The incidence of ISR was 4% after long DES stenting for coronary arteries. The long-term clinical prognosis of patients with long DES-ISR associated with coronary artery stenting might be benign, if the patient has optimal treatment.

Journal of Geographic Information System (JGIS) , 2018, DOI: 10.4236/jgis.2018.105032
Abstract: Urban Traffic Accidents (UTAs) may be seen as discrete events, localized in space and time. UTAs rates all over the world show great disparity, especially between developed and developing countries. Today, the most negative results of urban transportation are UTAs with many side effects such as injuries and loss of lives. UTAs lead to injury, death, disability and pain, loss of productivity, grief, social and mental problems. Proper and deep study and planning can enhance transport and driving safety and reduce number and severity of accidents. Traffic safety crises, death, damage and costs resulting from road UTAs are some of the most important public health and police organization challenges. In particular, UTA’s victims are often people who are aged 15 - 44 years old in Iran, and UTAs are the second cause of death after heart disease in Tehran. UTAs’ statistics in Tehran reveal a serious problem with significant fatality and injury rate. This study aims to identify the spatial pattern of UTAs in the city of Tehran in order to find the causes and consequences as well as the temporal and spatial or spatio-temporal variation of accidents. The relationship between the space and time of daily activities that generate urban daily trips and UTA, is examined in Tehran city for 2010 to 2011. The analysis is based on different primary and secondary data sources, which include locations of accidents and different attributes such as date, reason, kind, etc. Based on the data analysis, the study also attempted to show some light on the major causes, factors and types of accidents in order to identify the problem and suggest appropriate suggestions which reduce UTAs. As this study considered different factors of UTA, urban environment, land use, population, human activities and culture point considered as the most important pillars of this study. In order to understand knowledge, culture and attitudes of drivers towards traffic regulations, questionnaires were distributed to 1500 drivers in the study area to gather data about the drivers’ knowledge, beliefs, attitudes, and behaviors and 1177 of them returned. The results express that culture and knowledge of drivers have direct effects on localizing accidents. Furthermore, the concentration of educational, commercial and cultural activities that make up a large number of urban trips and urban dynamics, road usage, and time are among the main considerations of this study. The relationships between population, land use and dynamic patterns of city which constitute the urban structure, are used to establish a link
Application of GIS for Urban Traffic Accidents: A Critical Review  [PDF]
Niloofar Haji Mirza Aghasi
Journal of Geographic Information System (JGIS) , 2019, DOI: 10.4236/jgis.2019.111007
Abstract: The analysis of huge data is a complex task that cannot be executed without a proper system. Geographic information systems (GISs) have been used by many transportation agencies and police departments to analyze and manage urban traffic accident (UTA) data and for decision making aimed at decreasing accident rates and increasing safety. The exact location of accidents and environmental characteristics must be analyzed as UTAs occur in specific locations with specific characteristics. ArcGIS software is the best choice for obtaining meaningful information and analysis results from UTAs in an observational time span. GIS technology is a fundamental element for investigating and evaluating the complex spatial relationship among different components and urban traffic accident is one of them. Micro or macro analysis of UTAs through the spatial prospective within the geographical environment and urban structure can make a deep micro understanding of UTAs patterns in addition to assisting in decision making. UTAs can be considered complex events that occur in two aspects which are spatial and temporal or space and time in other word. A GIS can integrate more than two different and unrelated databases. The evaluation among different spatial objects in a geographical environment and associated factors in urban structure which are included but not limited to land use category, road transportation network qualification, population density, etc., is one of the GIS specification. Traffic safety organizations and UTA researchers use GISs as a key technology to support their research and operational needs. In particular, GIS-T is an often-used GIS application used for planning and decision-making in transportation.
