Early fault prediction and detection of hydrocephalus shunting system  [PDF]
Abdel Rahman Alkharabsheh, Lina Momani, Waleed Al-Nuaimy, Jafar Ababneh, Tariq Alwada’n, Abeer Hawatmeh
Journal of Biomedical Science and Engineering (JBiSE) , 2013, DOI: 10.4236/jbise.2013.63036
Abstract:

Trends of various intracranial pressure (ICP) parameters for high pressure hydrocephalus patients are utilized to detect various shunt faults in their early stages, as well as, to monitor the effect of such faults on shunt performance. A method was proposed to predict the time required for ICP to be abnormal and for the valve to reach full blockage condition. Furthermore, an auto valve schedule updating method is proposed and used to temporarily deal with detected faults until the patient is checked up by his/her physician. The proposed algorithms were evaluated using numerical simulation.

Grape Seed Extract (Vitisvinifera) Alleviate Neurotoxicity and Hepatotoxicity Induced by Lead Acetate in Male Albino Rats  [PDF]
Abeer M. Waggas
Journal of Behavioral and Brain Science (JBBS) , 2012, DOI: 10.4236/jbbs.2012.22021
Abstract: Grape seed extracts (GSE) are very potent antioxidant and exhibit numerous interesting pharmacologic activities, including an antioxidant property, and has been suggested to be of use in treatment of several diseases. The present study has been undertaken to investigate the protective and therapeutic effect of GSE against lead-induced neuro and hepatotoxicity in rat. Male albino rats were divided into six groups: the 1st group, rats were injected daily with saline vehicle and served as negative control, the 2nd group (positive control group), the rats were injected (i.p.) with subacute dose (100 mg/kg b·w/day) of lead acetate (LA). The 3rd group (protective group), the rats were injected (i.p.) with LA (100 mg/kg b·w/day) for 7 days after treatment with GSE (100 mg/kg b·w/day) for 3 weeks. The 4th, 5th and 6th groups (therapeutics groups), rats were injected (i.p.) with subacut dose (100 mg/kg b·w/day) of lead acetate for 7 days, then treated with GSE (100 mg/kg b·w/day) for one, two and three weeks, respectively. The level of norepinephrine (NE), dopamine (DA), serotonin (5-HT) and 5-hydroxyindol acetic acid (5-HIAA) were evaluated in brain regions (cerebellum, brainstem, striatum, cerebral cortex, hypothalamus and hippocampus). The result indicated that the administration of subacute dose of LA (100 mg/kg/day, i.p.) induce a significant decrease in NE, DA, 5-HT and 5-HIAA content in all tested brain regions. Also the obtained data showed significant increase in liver enzymes: serum glutamate oxaloacetate transaminase (GOT), serum glutamate pyruvate transaminase (GPT) and Lactate dehydrogenase (LDH) level in group 2 (positive control). There is an improvement in neurotransmitters content. Also the obtained data showed significant in- crease in liver enzymes of protective (G3) and therapeutics groups (G4, G5 and G6) which received GSE compared with animal group that received lead acetate (G2). This is may be the presence of proanthocyanidins and procyanidins which have antioxidant and free radical scavenging activities. The result suggests that grape seed extract may prevent lead-induced neurotoxicity and hepatotoxicity.
Applying the WHO instead of CDC growth charts may double obesity rates  [PDF]
Abeer Yasin, Guido Filler
Open Journal of Pediatrics (OJPed) , 2013, DOI: 10.4236/ojped.2013.32025
Abstract:

Aims: This study compares the WHO (2007) and the National Health Examination Survey (NHANES III) reference intervals and investigates the differences when applied on a Canadian cohort of older children and adolescents. Methods: We calculated height, weight and BMI z-scores of 4375 consecutive patients (1993 female, 45.6%) aged 5 - 20 years attending outpatient clinics at a single tertiary care centre using reference data of the latest NHANES (III) survey and the WHO (2007) growth charts. To address age dependency, data was stratified into age groups. Results: Using the NHANES III reference intervals, medians of weight (+0.46), height (+0.29) and BMI z-scores (+0.46) were significantly non-zero. The WHO (2007) growth charts yielded medians of +2.05, +0.32, +0.53 for weight, height and BMI z-scores respectively, all significantly non-zero. When comparing both growth charts, Canadian children had significantly different weight and BMI z-scores (p < 0.0001) with WHO growth charts whereas height z-score did not differ. Obesity rates (BMI z-score > 95th percentile) doubled from 8.6% to 16.0%. A significant age dependency was observed with higher WHO (2007) weight z-scores (>7 years) and higher BMI z-scores (7 to 13 years) and no significant difference was observed for height z-scores across all age groups. Gender differences were observed for weight z-scores (>9 years) and BMI (males: 9 - 11 years, p = 0.0118; 11 - 13 years, p = 0.0069) whereas no significant difference was found in height z-scores across all age groups. Conclusion: Our results reveal substantial differences between both reference populations and thus interpretation needs be done with caution, especially when labelling results as abnormal.

FLAVONOIDAL CONTENT OF VANGUERIA INFAUSTA EXTRACT GROWN IN EGYPT: INVESTIGATION OF ITS ANTIOXIDANT ACTIVITY
Temraz Abeer
International Research Journal of Pharmacy , 2011,
Abstract: Chromatographic purification of methanolic extract of Vangueria infausta leaves grown in Egypt led to isolation of five flavonoids namely luteolin-7-O- rutinoside, apigenin- 7-O- rutinoside, luteolin-4` -O- glucoside, quercetin-3-O-glucoside and quercetin. Also, the extract revealed both free radical (DPPH), H2O2 scavenging activities and reducing power potential as compared to rutin. The extract showed promising activity that may limit free radical and oxidative damage.

Abstract: Pharmacists can influence health outcomes and public healthin a variety of ways. Pharmacists in community, hospital, andother settings promote cost-effective use of medicines, reducemorbidity and mortality, reduce avoidable hospital admissions,reduce medication errors, improve rational use andprescribing of medicines, and increase access to healthcare andmedicines, particularly for underserved populations [1-11].Because of their knowledge of medicines and clinicaltherapeutics, pharmacists are suitably placed for task shiftingin health care and could be further trained to undertakefunctions such as clinical management [5, 6].

Prevalence of congenital hydrocephalus in the Hashemite kingdom of Jordan: A hospital-based study  [PDF]
Hana Dawood Ali Alebous, Abeer Ahmad Hasan
Natural Science (NS) , 2012, DOI: 10.4236/ns.2012.410104
Abstract: Background: Congenital hydrocephalus, an important cause of neurologic morbidity and mortality in children, is a medical condition characterized by an abnormal accumulation of cerebrospinal fluid in the brain. It can be caused by abnormal brain development, obstruction of the cerebral aqueduct flow, Chiari malformations, and Dandy-Walker malformation. The prevalence of congenital hydrocephalus is 2.2 to 18 per 10,000 live births. Objectives: To determine the prevalence of congenital hydrocephalus among livebirths in the Hashemite Kingdom of Jordan (HKJ). Methods: Clinical data were collected from medical records of all livebirths with congenital hydrocephalus born at Al Bashir Hospital, Amman/The Hashemite Kingdom of Jordan in 2004-2005 and 2008-2011. Descriptive analysis was carried out using the Statistical Package for the Social Science (SPSS 20). Results: The prevalence of hydrocephalus was 0.092% with a relative predominance among males. Conclusion: The study concluded that the prevalence of congenital hydrocephalus is comparable to that of developed countries. The efforts made by the Ministry of Health seem to have paid off. More research on stillbirths is recommended.
Reconnection of Vortex Bundles Lines with Sinusoidally  [PDF]
Sultan Z. Alamri, Abeer A. Alenezi
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.46130
Abstract: Using the vortex filament model with the full Biot-Savart law, we show that non-straight bundles of quantized vortex lines in HeII are structurally robust and can reconnect with each other maintaining their identity. We discuss vortex stretching in superfluid turbulence in many cases. We show that, during the bundle reconnection process, Kelvin waves of large amplitude are generated, in agreement with previous work and with the finding that helicity is produced by nearly singular vortex interactions in classical Euler flows. The reconnection events lead to changes in velocities, radius, number of points and total length. The existence of reconnections was confirmed by other authors using the model of nonlinear Schr?dinger equation (NLSE). Our results are agreed with the finding of other authors and extension to our numerical experiments.

Advances in Nanoparticles (ANP) , 2015, DOI: 10.4236/anp.2015.42007
Abstract: Ferric oxides have drawn significant interest due to their unique properties, relatively low cost, and due to their potential applications in different fields. In this work, cobalt (Co) doped iron oxide (Fe2O3) powders, with crystalline size 36.97 nm were successfully prepared using a microwave- hydrothermal process for the first time and characterised using different techniques. The morphology of the samples was characterised by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive analysis of X-ray spectroscopy (EDAX), Fourier transform infrared (FT-IR) spectroscopy and ultraviolet-visible (UV-Vis) spectroscopy. The images show monodispersed particles with a sharp-edged square morphology. It was found that the average size was about 33.3 nm for Fe2O3 and 36.97 nm for Co-Fe2O3. The Co atomic percentage dopants were approximately 5.73%. The nanosized synthesised materials in this study may find an application in the areas of removal of toxic metal and dyes research.
