In this research, for the first time, we successfully developed ultrasonic-assisted extraction and dispersive liquid-liquid microextraction combined with gas chromatography-mass spectrometry as a new, fast and highly sensitive method for determining of acrylamide in potato chips samples. Xanthydrol was used as a derivatization reagent and parameters affecting in the derivatization and microextraction steps were studied and optimized. Under optimum conditions, the calibration curves showed high levels of linearity (R(2)>0...

BACKGROUND: Blood products are used for patient treatment and survival in the cases of major surgery, hematological disorders or cancer therapy. Presently the main blood components are not yet replaceable by artificial products and all activities related to blood transfusion is highly dependent on the healthcare development of each country. The World Health Organization Eastern Mediterranean Region (WHO-EMR) comprises of 21 member states with variable socio-economic status effective on blood transfusion activities...

BACKGROUND: Cardio-ankle vascular index (CAVI) was supposed to be an independent predictor for vascular-related events. Biomarkers such as homocysteine (Hcy), N-terminal pro-brain natriuretic peptide (NT-proBNP), and urine albumin(microalbumin) (UAE) have involved the pathophysiological development of arteriosclerosis. The present study was to investigate relationship between CAVI and biomarkers in vascular-related diseases. METHODS: A total of 656 subjects (M/F 272/384) from department of Vascular Medicine were enrolled into our study...

Alkaline treatment (Alk) combined with ultrasound-assisted extraction (UAE) (Alk+UAE) was examined as a means of extracting tocols and γ-oryzanol from rice bran into an organic phase while simultaneously recovering ferulic acid into an aqueous phase. The tocols and -oryzanol/ferulic acid yields were determined using high-performance liquid chromatography with fluorescence and UV detection. The effects of extraction conditions were evaluated by varying the Alk treatment temperature and extraction duration...

Epidemiological data of renal diseases have great geographic variability throughout the world. Due to the lack of a national renal data registry system, there is no information on the prevalence rate, clinical and pathological features of various glomerulonephritis (GN) in the United Arab Emirates (UAE). In a retrospective cross-sectional study, we analyzed 158 renal biopsies done in Dubai Hospital, UAE, between the years of 2005 and September 2014, with an aim to determine the prevalence rate and frequency of different pathological patterns of GN in adult patients who presented with proteinuria ± hematuria...

Benign metastasizing leiomyomas (BMLs) are rare sequelae of common uterine leiomyomas and most frequently found in the lungs. Most cases of BMLs occur with a history of prior gynecologic procedures; however, none have yet been reported in association with uterine artery embolization (UAE). This case report highlights the disease course for a 48-yo female with a history of both myomectomy and UAE for uterine fibroids who presented later with bilateral pulmonary BMLs. Though the pathophysiology of BMLs is poorly understood and this case is confounded by prior myomectomy, it does bring into question whether UAE has a role in BML development...

BACKGROUND: This study looks at access to care for Juvenile Idiopathic Arthritis through pediatric rheumatology in the UAE, as an example of multi-ethnic society. METHODS: Patients with a diagnosis of Juvenile idiopathic arthritis were identified through the hospital electronic medical records system from January 1st 2011 to December 31st 2014. All residents of the United Arab Emirates hold an Emirates identity card. We divided our patients into two groups: Emirati-Emirates, who are native Emirati children and hold the Emirati nationality, as stated on their Emirates identity card, and who therefore have full, comprehensive access to free medical care; and non-Emirati-Emirates, who represent other nationalities, as stated on their Emirates identity card...

PURPOSE: To compare acute pain after uterine artery embolization (UAE) with tris-acryl gelatin microspheres (TAGM) versus gelatin sponge particles (GS) for leiomyoma. MATERIALS AND METHODS: This was a single-institution, retrospective study. Between July 2008 and November 2016, 101 consecutive patients with symptomatic uterine leiomyoma underwent UAE with the same protocol for post-procedural pain. GS was employed with near-stasis endpoint for the first 49 patients, whereas TAGM was used with limited endpoint for the next 52 patients...

Aim. In this study, we aimed to investigate the effects of febuxostat, a novel inhibitor of xanthine oxidase (XO), on renal damage in streptozotocin- (STZ-) induced diabetic rats. Methods. Diabetes was induced by the intraperitoneal injection of STZ in male Sprague-Dawley rats. Sham-injected rats served as controls. The control and diabetic rats were treated with and without febuxostat for 8 weeks, respectively. Fasting blood and 24-h urine samples were collected every 4 weeks. Rat livers were extracted for detecting gene expression, content, and bioactivity of XO...

PURPOSE: To study the factors that might impact infarction of individual uterine leiomyomas and total tumor burden after uterine artery embolization (UAE). MATERIALS AND METHODS: This retrospective study included 91 patients (mean age, 44 y [range, 34-54 y]) who underwent UAE with tris-acryl gelatin microspheres (TAGMs) or nonspherical polyvinyl alcohol (PVA) particles. Twenty-one patients were treated with PVA (23%) and 70 were treated with TAGMs (77%). A total of 356 uterine leiomyomas were assessed, with a median uterine volume of 533 cm(3) (range, 321-848 cm(3))...

BACKGROUND: The short and long-term relationship between hyperglycemia and PTH level among patients suffering from both diabetes type 2 and vitamin D deficiency were evaluated. METHODS: This was a cross sectional study performed at Dubai Diabetes Center, UAE. To demonstrate the relationship between hyperglycemia and PTH level, subjects with type 2 diabetes and vitamin D deficiency (124 adults) were divided into 4 groups based on their FPG and HbA1c levels. RESULTS: Mean vitamin D and PTH levels among subjects with HbA1c≤7% (53mmol/mol) were 14...

This work investigated the extraction efficiency of polyphenols (anthocyanins) from blackberry, blueberry and grumixama residues using combined ultrasonic assisted extraction (UAE) and pressurized liquid extraction (PLE) (UAE+PLE). The performance of UAE+PLE was compared to those achieved by the isolated PLE and UAE methods and conventional Soxhlet extraction. The effects of the extraction methods and solvents (acidified water pH 2.0, ethanol+water 50% v/v and ethanol+water 70% ethanol v/v) on total phenolics content, anthocyanin composition and antioxidant capacity of extracts were investigated by a full factorial design...

The emergence of pan-resistant Klebsiella pneumoniae strains is an increasing concern. In the current study we describe a cluster of 9 pan-resistant K. pneumoniae ST147 isolates encountered in 4 patients over nearly one year in 3 hospitals of the United Arab Emirates. The isolates exhibited highly similar genotypes. All produced chromosomally encoded OXA-181 and the majority also produced the NDM-5 carbapenemase. Similarly to the previously described single isolate from the UAE, MS6671, the mgrB was disrupted by a functional, ISEcp1-driven blaOXA-181 insertion causing resistance to carbapenems...
