BACKGROUND Bronchial asthma is common in Kuwait, a desert country, but the sensitizing allergens are uncertain. This study investigated the sensitizing allergens in Kuwaiti patients with extrinsic asthma. METHODS A total of 553 asthmatics (male:female ratio: 1.4; mean age: 31.7 years [range 3-76 years]) and 112 matched controls were studied. Sera from all(More)
BACKGROUND The causative allergens of allergic rhinitis in desert environments are uncertain. OBJECTIVE To determine the sensitizing aeroallergens in patients with allergic rhinitis in Kuwait, a desert country. METHODS A total of 706 patients aged 6 to 64 years (mean 34.3 years) with allergic rhinitis were studied. Sera from the patients were screened(More)
This study presents the applicability of an ensemble of artificial neural networks (ANNs) and learning paradigms for weather forecasting in southern Saskatchewan, Canada. The proposed ensemble method for weather forecasting has advantages over other techniques like linear combination. Generally, the output of an ensemble is a weighted sum, which are(More)
BACKGROUND The reference total serum immunoglobulin (IgE) values and the usefulness of total IgE values in the diagnosis of allergy have not been established for the Kuwaiti population. The literature reference values may not be applicable since such values often vary among ethnic nationalities. OBJECTIVE The aim of this study was to establish the(More)
Long non-coding RNAs (lncRNAs) are critical in the regulation of various biological processes. In recent years, plethora of lncRNAs have been identified in mammalian genomes through different approaches, and the researchers are constantly reporting the regulatory roles of these lncRNAs, which leads to complexity of literature about particular lncRNAs.(More)
The presence of IgE receptor Fc epsilonRIbeta polymorphism (181/183) was investigated in Kuwaiti asthmatic patients and controls using an allele refractory mutation screening (ARMS) test. The variant sequence (Leu181/Leu183) was detected in 72% (320/442) chromosomes analysed. Homozygous LL genotype was detected in 48% (46/96) asthmatic subjects compared to(More)
BACKGROUND The importance of fungal allergens in the development of allergic diseases in a desert environment is uncertain. This study evaluated the prevalence of IgE sensitization to moulds among patients with allergic respiratory diseases in Kuwait - a desert country. METHODS A total of 810 patients (male:female ratio 1.4) with a mean age of 32.3 years(More)
BACKGROUND Respiratory allergies are common in Kuwait, and the role of certain allergens has been previously documented. OBJECTIVE To evaluate the results of skin prick tests to a range of allergens that were considered relevant to the vegetation surveys and aerobiological studies performed in Kuwait. METHOD New patients attending our center during(More)
This paper presents a comparative study of different neural network models for forecasting the weather of Vancouver, British Columbia, Canada. For developing the models, we used one year’s data comprising of daily maximum and minimum temperature, and wind-speed. We used Multi-Layered Perceptron (MLP) and an Elman Recurrent Neural Network (ERNN), which were(More)
