Background :The studies have shown that stroke morbidity and mortality could be decreased if early diagnosis and treatment is delivered faster for patients. This tool is designed based on all Pre-hospital stroke scales across the world as well as experiences of the emergency medicine specialists and pre-hospital emergency technicians to improve the diagnostic accuracy of the stroke scale in I...

Many analytics applications generate mixed workloads, i.e., workloads comprised of analytical tasks with different processing characteristics including data pre-processing, SQL, and iterative machine learning algorithms. Examples of such mixed workloads can be found in web data analysis, social media analysis, and graph analytics, where they are executed repetitively on large input datasets (e....

The pre-analytical, analytical and biological sources of variation were estimated for serum lipoprotein(a) concentrations, as measured with a new commercially available procedure. There were no significant differences between the concentrations of lipoprotein(a) measured in EDTA plasma and serum. The analyte is stable in specimens stored for up to two weeks in the refrigerator, or up to three m...

Unlike other vitamins, the vitamin D concentration in blood varies cyclically over the course of the year in relation to genetic (gender, ethnicity, polymorphisms) and environmental factors (sunlight exposure, diet, food-related or direct vitamin D supplementation, skin pigmentation). Although the major diagnostics manufacturers have recently developed improved automated 25-hydroxy vitamin D im...

Near infrared spectroscopy (NIRS) methods were developed for the determination of analytical content of an antimalarial-antibiotic (artesunate and azithromycin) co-formulation in hard gelatin capsule (HGC). The NIRS consists of pre-processing treatment of spectra (raw spectra and first-derivation of two spectral zones), a unique principal component analysis model to ensure the specificity and t...

this research is on the improvement of the procedure to determination of trace levels of antidepressant drug; fluoxetine in wastewaters. in this research a silica based sol-gel was applied for the extraction of fluoxetine from water samples. this two-phase technique is consisting of aqueous samples of fluoxetine (donor phase) and silica based nanocomposite prepared by sol-gel technique (accepto...

Alzheimer's disease (AD) is the most common form of dementia in humans, and a major public health concern with 35 million of patients worldwide. Cerebrospinal fluid (CSF) biomarkers being early diagnostic indicators of AD, it is essential to use the most efficient analytical methods to detect and quantify them accurately. These biomarkers, and more specifically amyloid-β (Aβ) peptides, are meas...

This paper presents a novel phase precoding (pre-equalization) technique to equalize frequency-selective Rayleigh and Rician slowly fading channels for personal communication systems using phase modulation. In order to achieve intersymbol interference (ISI)-free transmission, the precoding technique predistorts the signal transmitted from a base station to a portable unit. The novelty of the te...

Results of plasma microparticles (MPs) measurements reported in the literature vary widely. This is clearly not only related to the lack of well-standardised MP assays, but also to variations in pre-analytical conditions. In this review we will discuss the pre-analytical variables related to plasma and MP preparation which may affect MP analysis. Additionally we will address several analytical ...

Previous medico-legal autopsy diagnoses after sportrelated deaths in our personal experience in Durban included cardiomyopathy, coronary artery disease, Marfan’s syndrome and ruptured cerebral berry aneurysms. It is regrettable that autopsies were not performed in the above cases. Whether they should have been considered natural or unnatural may be debatable, but postmortem examinations could h...
