Influence of Antibiotics Treatment on Hematological Aspect in Chickens
Ali A.S. AL-Mayah,Jalaa A. AL-Ahmed
International Journal of Poultry Science , 2005,
Abstract: Two experiments were described in which sixty one-day old (IPA) chicks were distributed into four equal groups, three for treatment & the other for control. Ampicillin, Enrofloxacine or Amoxicillin were used for five consecutive days via drinking water for treatment for at the first and twenty second day of life. Five birds from each group were slaughtered on 6 and 28 days post treatment and hematological examinationsperformed on blood samples collected just prior to slaughter. Changes in PCV, HB, RBC, WBC, MCV, MCH and MCHC were observed. The investigations demonstrated a fall in hematological values in body chicks, Whereas in older ages these values were analogous with normal ranges. The changes were not substantiate the presence of anemia. They might be an indications of an incidental haemodilutionin the hematological observed in this study.

Abstract: Food allergy is a common problem encountered by primary care physicians. It is estimated to affect 4 to 8% of children and 1 to 2% of adults and is considered a major cause of life-threatening hypersensitivity reactions [1-3]. Eight foods are responsible for more than 90% of food allergies: cow's milk, egg, soy, wheat, peanut, tree nuts, fish, and shellfish [4]. Among those foods, peanut has attracted considerable attention for several reasons. Peanut allergy is common, typically with onset in the first few years of life. Allergy to peanut usually is lifelong and accounts for most of the food-induced severe and fatal allergic reactions [5]. Hence, the diagnosis of peanut allergy carries with it considerable medical and emotional significance [6].The prevalence of anaphylaxis from all causes is rising, but food-induced anaphylaxis is causing a disproportionate increase in the rates of anaphylaxis [7]. A recent study in the United States assessed the prevalence of peanut allergy by random telephone survey. The prevalence of peanut allergy was estimated to affect 0.8% of children and 0.6% of adults, [8] showing a twofold increase over a 5-year period [9]. In the Isle of Wight, United Kingdom, a study was conducted on a birth cohort of 3- and 4-year-old children born between 1994 and 1996, and the results were compared with those of a cohort born in 1989. There was a documented twofold increase in reported peanut allergy (0.5-1.0%) and a threefold increase in sensitization, and after further analysis that included oral challenges, the total estimate for clinical peanut allergy was 1.5% of 3- to 4-year-old children [10]. The results from those two studies are suggestive of an overall increase in the prevalence of peanut allergy among children. Another study estimated the prevalence of peanut allergy to be 1.34% among primary school children in a Canadian province [11].Allergies to peanut have a spectrum of clinical presentations ranging from cutaneous manifestations to l

Sensors , 2009, DOI: 10.3390/s91209965
Abstract: A novel enzyme immobilization platform was prepared on a platinum disk working electrode by polymerizing aniline inside the interstitial pores of polyester sulphonic acid sodium salt (PESA). Scanning electron microscopy study showed the formation of homogeneous sulphonated polyaniline (PANI) nanotubes (~90 nm) and thermogravimetric analysis (TGA) confirmed that the nanotubes were stable up to 230 °C. The PANI:PESA nanocomposite showed a quasi-reversible redox behaviour in phosphate buffer saline. Horseradish peroxidase (HRP) was immobilized on to this modified electrode for hydrogen peroxide detection. The biosensor gave a sensitivity of 1.33 μA (μM)-1 and a detection limit of 0.185 μM for H2O2. Stability experiments showed that the biosensor retained more than 64% of its initial sensitivity over four days of storage at 4 °C.

Food and Nutrition Sciences (FNS) , 2012, DOI: 10.4236/fns.2012.33046
Abstract: Previous studies have shown that underreporting of energy intake is common when assessing dietary intake, particularly in the overweight and obese. The aim of this study was to obtain an estimate of energy and macronutrient intake according to weight status and to investigate underreporting among Iraqi people living in the UK. Twenty eight adult volunteers (n = 16 males) were recruited. Dietary intake was estimated 3 times using the 24 hour dietary recall tech-nique. Portion size was estimated using household measures and the Photographic Atlas of Food Portion Sizes. Energy and macronutrients estimations were calculated, and weight and height were measured to calculate Body Mass Index (BMI). Energy intake was compared to estimated basal metabolic rate (BMR) and the Goldberg equation was used to assess underreporting. Of the overall sample, 57.1% (n = 16) and 21.4% (n = 6) subjects were overweight and obese, respectively. The mean energy intakes were low for males (1977 kcal/d) and females (1586 kcal/d). The percentage of under-reporters was high (57.1%) and this was higher in overweight and obese subjects (68.1%) compared to those of normal weight (4.5%). Overweight and obesity are common among well-educated Iraqi people. Underreporting of energy intake is common especially among overweight and obese Iraqi individuals.

Mahmoud A. Hafez, Ahmed Mounir Al-Dars
Modern Plastic Surgery (MPS) , 2012, DOI: 10.4236/mps.2012.24023
Abstract: Injury from sea urchin spines is not rare, especially during summer holidays in the sea side. Failure to remove these spines or inability to remove them completely can lead to long-term squeal of pain and impaired function. Treatment methods include alternative medicine, LASER and surgery. We describe the surgical removal of 102 sea urchin spines from the foot of a 36-year-old man. The wounds healed completely. Although, he initially complained of a mild discomfort on weight bearing, the symptoms disappeared 2 weeks later.

Food and Nutrition Sciences (FNS) , 2014, DOI: 10.4236/fns.2014.513127

The study aimed at analyzing the most important factors affecting the retail marketing of honey in Saudi Arabia. Cross sectional survey was employed using field interview (direct contact) with a random sample of 343 retail outlets represented all its forms and patterns in seven major cities in Saudi Arabia. Measurements like market share, Gini coefficient and Herfindahl Hirschman Index (HHI) were used to estimate the indicators of market structure and its performance. The result showed that the structure of honey retail market is generally closer to pure competition with a small concentration in some areas. Gini coefficients of concentration, as well as the values of the Herfindahl Hirschman Index (HHI) were relatively low for retailers. The average marketing margin was about SAR 6.4/Kg for local honey while the marketing margin of imported honey was about SAR 113/Kg. The high profit margin variation between local and imported honey is due to the high marketing costs, lower supplied quantity and higher demand for local honey. The estimated cost of marketing of onekilogram of honey was about 8 SAR at the retail level. From retailers’ point of view, low quality, lack of marketing services, improper display, high rental property, lack of knowledge and experience of the consumer about properties and quality characteristics honey, high prices and shortage of some varieties of honey in some specific season are the most important problems of honey marketing in the Saudi market. Setting priorities between different brands of honey plays a noticeable role in marketing. Some honey producers and traders were very concerned about unfair competition of honey market through high promotion as a brand based on their long history in the production and supply of high-quality varieties of honey from specific and well-known varieties. Hence, intensive awareness creation effort through training, exhibition, media and advertisement are required to improve the perception of consumers towards the local honey.

Open Journal of Nephrology (OJNeph) , 2014, DOI: 10.4236/ojneph.2014.41006

Background: Neuttrophil gelatinase associated lipocalin (NGAL) was shown to be a good marker for predicting acute kidney injury (AKI). Some recent reports demonstrated that NGAL may be an early biomarker for kidney affection in diabetic patients. The aim of this work is to investigate urinary NGAL (UNGAL) in type 2 diabetic patients with and without albuminuria. Methods: This study included 46 type 2 diabetic patients and 15 healthy age and sex matched individuals as the control group. Diabetic patients were divided into three groups according to urinary albumin excretion (UAE), normoalbuminuria, microalbuminuria and macroalbuminuria. UNGAL was measured in all populations and corrected to urinary creatinine to account for day to day variation in urine volume and transformed log. Comparison between 4 groups (control, normoalbuminuria, microalbuminuria and macroalbuminuria) was done. Results: Log UNGAL/Creatinine ratio showed significant difference when comparing control group (0.70 ± 0.58) versus normoalbuminuria (1.71 ± 1.06), microalbuminuria (1.57 ± 0.72) and macroalbuminuria (1.92 ± 0.63), however,

Physics , 2013,
Abstract: In this work the estimation of the lateral distribution function in Extensive Air showers was performed by using a system for air shower simulations which is called AIRES version 2.6 for different hadronic models like (QGSJET99, SIBYLL and SIBYLL1.6). The simulation was fulfilled in the high energy range (10^15-10^19 eV) for different primary particles like (gamma, protons and iron nuclei) for vertical showers. This simulation can be used to reconstruct the type and energy of the particle that generated Extensive Air showers for charged particles that registered with different arrays.

Stem Cell Discovery (SCD) , 2016, DOI: 10.4236/scd.2016.61001
Abstract: In the brain, there are hundreds of types of specialized neurons and to generate one type of them we need to have neural progenitors for differentiation to specific neuron type. Mesenchymal stem cells (MSCs) are easily isolated, cultured, manipulated ex vivo, showing great potential for therapeutic applications. The adult MSCs have the potential to produce progeny that differentiate into a variety of cell types such as neurons. This fact suggests that MSCs derived neurons are an important cell type and a deep understanding of the molecular characteristics of it would significantly enhance the advancement of cell therapy for neurological disorders. Therefore, in this study, we isolated, identified, and studied neural progenitors by measuring expression levels through neurogenesis pathway of three neural differentiation markers nestin (NES), neurofilament (NF-L), and microtubule association protein (MAP-2) from mouse bone marrow MSCs (mouse bmMSCs) by using butylated hydroxyanisole (BHA) and diethyl sulfoxide (DMSO) as neural inducers agents. The results of immunocytochemistry and Real Time-PCR showed that in contrast to MSCs, neural differentiated cells showed neural progenitor pattern by showing stable increase in NES gene expression through differentiation process with increasing the protein expression through different exposures times, while NF-L gene and protein expression start to increased after 48 h but not replaced the NES expression completely even when its expression passed NES levels. The maturation marker Map-2 expression was low during the duration of differentiation period in protein and gene expression, which prove that these cells are still progenitors and can be redirected into specific type of neurons by further treatments.
