Design of Validation Study of the Lower Extremity Functional Status Scale for Anterior Cruciate Ligament Reconstruction in Arabic Speaking Athletes
Authors: Amy Leona Sandridge and Michael SarestskyAbstract Background: The Lower Extremity Functional Scale (LEFS) has been found to be reliable and valid in several populations and languages. This 20-question scale is a self-report measure, which assesses the ability of persons with any musculoskeletal condition related to the lower extremity from 0 to 80. The objective measurements used to compare it will be the 40-meter fast self-paced walk [SW], timed up-and-g Read More

Temperature Circadian Variations in Worker in a Hot Environment in Qatar
Abstract Background: Body core temperature fluctuates during the day following a sinusoidal variation with a maximum acrophase in the late afternoon. This circadian rhythm is mainly endogenous but it can be influenced by environmental factors such as work and social and physical activities. Objectives: 1) To verify if aluminum shift-workers would present different core temperatures at different times of the day (i.e. Read More

Prevalence of Smoking and Exposure to Secondhand Smoke among Qatari School Children: Results from the Pilot Phase of the National Epidemiological Study of Lung Health among Qatari National School Children
Authors: Amy Leona Sandridge, Hana Said, Amjad Tuffaha and William GreerAbstract Secondhand exposure to tobacco smoke (SHS) has been proposed to potentially increase risk of acute respiratory infections, middle ear disease, exacerbated asthma and decreased lung function in children. The objectives of this study of Qatari schoolchildren were six-fold: to assess feasibility of a national study on athletic participation, healthy living and lung function; to provide estimates of height and weight; to esti Read More

Negative Influence of Intermittent Ramadan Fasting and Unhealthy Lifestyle on Body Composition, Sleep, Physical Fitness and Iron Indices in School Boys
Abstract Background: Schoolchildren must practice healthy diet as well as active lifestyle to support their physical growth and development. Previous studies have shown that intermittent fasting can affect dietary intake, sleep duration and circadian patterns among adults, but there is a lack of related literature in schoolchildren. Purpose: The aim of this study was to objectively assess the effect of Ramadan fasting on phy Read More

Combined Temperature and Altitude Challenges do not Exacerbate the Degree of Muscle Fatigue Despite Shorter Cycling Time to Exhaustion
Authors: Olivier Girard and Sébastien RacinaisAbstract This study investigated the combined effect of environmental temperature [neutral (22°C/30%rH) vs. warm (35°C/40%rH)] and altitude challenge [sea level (FIO2 0.21) vs. reduced O2 content (FIO2 0.15)] on locomotor performance and the degree of end-exercise neuromuscular fatigue. Eleven physically active subjects cycled to exhaustion at constant workload (66% of their VO2max) in four different environment Read More

Neuromuscular Function Following Exercise-Heat Stress: Influence of Exercise Modality
More LessAbstract Background: Exercise-induced hyperthermia is associated with a decrease in force production capacity during brief (<5 seconds) and sustained (>10 seconds) maximal voluntary isometric contractions (MVIC). A reduction in central nervous system drive to exercising muscles is suggested to mediate this decrement to prevent thermal injury. Until recently, the influence of exercise modality on neuromuscular func Read More

A New Innovative Therapy for Sports Related Soft Tissue Injuries: Platelet-Rich Plasma (PRP)
Authors: Hans Tol, Bruce Hamilton and Hakim ChalabiAbstract Introduction: Platelet-rich plasma (PRP) is the cellular component of plasma that settles after centrifugation, and contains numerous growth factors. There is increasing interest in the sports medicine about providing endogenous growth factors directly to the injury site, using autologous blood products such as PRP, to potentially facilitate healing and earlier return to. Despite this interest, and apparent widespr Read More

Automated Marking of Sleep Spindles using Wavelet Packet Decomposition and Peak Tracking
Authors: Abdul Jaleel Palliyali, Reza Tafreshi, Beena Ahmed, Zurwa Khan and Hassan Al-HailAbstract Sleep spindles, along with K-complexes are hallmarks of stage 2 non rapid eye movement (NREM) sleep EEG. Sleep spindles are of significant interest because they are associated with phenomena such as ‘stability’ of sleep, updating of knowledge with new memories, processing of sensorimotor and mnemonic information. Therefore, accurately marking their presence in sleep recordings is essential. Accurate ide Read More

Electrocardiogram QRS Detection Using Temporal Correlation
Authors: Jongil Lim, Reza Tafreshi and Abdul JaleelAbstract Myocardial infarction (MI) is one of the most common sudden onset heart diseases. Early diagnosis of MI is essential for management and treatment initiation. Electrocardiogram (ECG), as a noninvasive electrical recording of the heart behavior is one of the most reliable diagnostic tools for identifying patients with suspected MI. The QRS complex is the major feature of an ECG. There have been many researches for QRS Read More

Deformation of Imbedded Blood Vessels Due to Uniform Pressure
More LessAbstract We consider the deformation of a blood vessel imbedded in soft tissue that is surrounded by a rigid structure. The vessel deforms when the difference between its external and internal pressures exceeds a certain value. To represent the deformation, we use a physical model consisting of two concentric cylinders tethered by numerous nonlinear springs representing the biological tissues surrounding the vessel Read More

Elevation of Alpha Acid Glycoprotein (AGP) does not Correlate with the Resistance of Chronic Myeloid Leukaemia (CML) to Imatinib Mesylate (IM)
Authors: Nader Izz Eddin Al-Dewik, Hanadi El Ayoubi, Andy Jewell and Hisham MorsiAbstract Background: Despite the efficacy of IM in treating CML, high degree of resistance has already been noted. AGP may reduce drug efficacy through its ability to interact with IM. Objectives: Could the level of AGP be correlated with CML resistance/response to treatment and if it could be employed as a biological marker for CML resistance. Methods: 25 CML patients were investigated for AGP level, serum samples were an Read More

BCR-ABL Kinase Point Mutations don't Correlate with the Resistance of Chronic Myelocytic Leukemia (CML) to Imatinib Mesylate (IM); A Study on CML Patient Population in Qatar
Authors: Nader Izz Eddin Al-Dewik, Hanadi El Ayoubi, Andy Jewell and Hisham MorsiAbstract Background: More than 45% of CML patients in Qatar resist the first line of treatment; Internationally, certain ABL mutations are the most common cause of IM resistance Objectives: To screen for BCR-ABL kinase mutations in CML patients treated in Qatar and to study if point mutations can be correlated with resistance to treatment. Methods: Peripheral Blood (PB) and Bone Marrow (BM) samples were collected from 25 Read More

Role of Homocysteine Measurement for Early Diagnosis of Vitamin B12 Deficiency in the First Days of Life
Authors: Tawfeg Ben-Omran, Noora Shalbik, Hongying Gan-schreier, Ghassan Abdoh, Rehab Ali and Georg HoffmannAbstract Background: Vitamin B12 (vit B12) deficiency is one of the major causes of megaloblastic anaemia and should be avoided as early as possible since a supplementation of mother and child can prevent neurological symptoms of the baby. Furthermore, the neurological symptoms of affected children are (partially) reversible. Elevated methylmalonic acid in urine and homocysteine (Hcy) in plasma are sensitive indicato Read More

Partial Analysis of Olfactory Receptor Subgenome in the Arabian Camel
Authors: Atef Khalaf Sayed, Jilian Rowe, Karsten Suhre and Benjamin ShykindAbstract Many animals have evolved mechanisms to withstand the harsh desert environment, characterized by extreme high temperatures and scarce water supplies. The Arabian Camel, and the Arabian Oryx are valued economically and culturally. These animals can survive for several days without food or water. As the Arabian peninsula undergoes rapid and vast industrial changes, it is increasingly important to understand t Read More
