Chemical and Microbiological Evaluation of Raw Buffalo Milk Locally Produced in Sharkia Governorate

A total of 100 samples of raw Buffalo milk including (50 from dairy shops and 50 from dairy farms) were collected randomly at Sharkia Governorate for chemical and microbiological evaluation. Chemical assessment of the milk samples collected from dairy shops revealed that the mean values of Fat, Solid Not Fat (SNF), Protein, Lactose and Salts percentages were 6.06±0.36, 9.08±0.23, 3.54±0.09, 4.73±0.14 and 0.74±0.02 respectively, while dairy farm samples were 6.18±0.31, 9.53±0.44, 3.89±0.09, 5.12±0.15 and 0.78±0.03; correspondingly. Microbiological examination revealed that the mean values of faecal coliforms were 2.03×106 ± 0.75×106 and 1.8×106 ± 0.59×106 in dairy shops and farms, respectively. The identified species of isolated coliform organisms in both types of milk wereCitrobacter diversus (11.3% vs 11.1%) Citrobacter freundii (9.6% vs 9.6%), Enterobacter aerogenes (12.1% vs 9.6%), Enterobacter agglomerans (11.3 vs 10.4%), Enterobacter cloacae (13% vs 11.1%), Klebsila oxytoca (9.6% vs 11.9%), Klebsila pneumoniae (9.6% vs 10.4%) and E.coli (23.5% vs 25.9%); respectively. Mean values of total staphylococci were 4.29×106 ± 0.21×106 and 8.08×106 ± 2.27×106 in milk samples of shops and farms respectively.The identified species in both types were S. aureus, S. epidermidis, S. saprophyticus, S. capitis and S. intermedius with percentages of 28% vs 35%, 48% vs 41%, 10% vs 12%, 8% vs 7% and 6% vs 5%; respectively. It was exposed that 8 strains (28.57%) and 10 strains (28.57%) were identified as methicillin-resistant S. aureus that containing mecA gene. In conclusion, high prevalence of different udder pathogens among dairy animals may attributed to the lack of sanitary conditions that adapted in dairy farm. So, restriction to application of hygienic measures in dairy farms as well as quality control and quality assurance programs should be adopted to get safe and good quality raw milk.
The Rheological Properties of Semolina Doughs: Influence of the Relative Amount of Ingredients

In the present study, the rheological properties of doughs, prepared by mixing semolina with water, yeast and salt, were investigated with different relative amounts of the ingredients. The rheological measurements were carried out by an Anton Paar MCR 102 rheometer, equipped with a plate-plate fixture. In more detail, frequency sweep tests were performed. Indeed, frequency sweep measurements showed to be informative about the force and extension of the gluten network that, in turn, demonstrated to depend on the relative amount of ingredients. The oscillatory experiments were analyzed by means of the “weak gel model”, whose parameters are directly related to such physical properties. It was found that doughs obtained with different amounts of ingredients showed significant differences in the rheological responses. The addition of yeast led to a significant viscosity and force network decrease, whilst the presence of salt produced an improve of the three-dimensional gluten network characteristics and, consequently, to the machinability of the dough. The study aims at contributing to a more efficient controllability in the industrial production of flour and semolina dough based foods, and in particular to that of “pani carasau”, a typical high quality and valuable Sardinian bread, since this process is high energy consuming (mainly in the baking step), in order to decrease the amount of off-specification products, and so making the processes more energy efficient and sustainable.
Gastric Cancer- Clinical Profile from a Single Center Experience in South India

Gastric cancer is one of the major causes of mortality in South East Asian countries with India being no exception. We carried out this retrospective observational study to highlight the clinical profile of gastric cancer in south India as there is sporadic data regarding the same. This study was carried out at a tertiary care oncology center in South India and 52 patients of gastric adenocarcinoma confirmed histopathologically and by immunohistochemistry were studied from January 2012 to December 2014. The male to female ratio was 2.25:1. The main presenting symptoms were pain abdomen and loss of appetite. The stage wise distribution of the cohort was as follows –2 patients of stage 1, 12 patients of stage 2 , 3 in stage 3 and 8 patients of metastatic disease( stage 4) . There were 21 patients who had locally advanced cancer at presentation. Histologically, all were adenocarcinoma, with 6 being signet ring and 7 poorly differentiated carcinoma. The treatment procured was as follows- 17patients were operated upon and 36 patients received chemotherapy. The regimens administered were as follows - ECF in 24 patients, Mc Donald’s regime in 1 patient, DCF in 4 patients, Cisplatin +5 Fluorouracil+ Leucovorin in 3 patients, paclitaxel+carboplatin in 1 patient, FOLFOX in 1 and docetaxel +cisplatin in 2 patients. 5 patients didn’t complete evaluation and received no treatment. Further studies are required to analyse the outcome of this dreaded malignancy in India.
Green synthesis, Optimization and Characterization of SiO2 nanoparticles using Aspergillus tubingensis F20 isolated from drinking water

This study aimed to demonstrates a positive correlation between silica metal tolerance ability of a drinking water fungi and its potential for the synthesis of silica oxide (SiO2) nanoparticles (NPs). Metal oxide NPs can be synthesized biologically by different methods including; microorganisms, plant extracts and or plant biomass. These methods in some time are better alternatives to the chemical and physical methods through an environmentally route. In the present work, twenty fungal strains were isolated from eight potable water samples and tested for producing silica nanoparticles (SiO2NPs), using precursor salt Dipotassium fluorosilicate (K2SiF6). Out of these twenty fungal strains, only one fungal isolate had the potency to reduce metal salt into metal NPs, which was identified by a molecular assay as Aspergillus tubingensis F20, and was assigned an Accession number of (MK226258.1) using the NCBI GenBank database. The factors affecting mono-dispersed production of SiO2 NPs such as; reaction times, incubation temperatures, hydrogen ion concentrations (pH) and salt concentrations were optimized. It is revealed that 10-3 M precursor salt concentration, 72 h of reaction time at pH 3, and an incubation temperature 28°C are the optimum conditions for the production of smaller size NPs. The biosynthesized NPs was characterized using several techniques including; Dynamic light scattering (DLS), Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), and Energy dispersive X-ray spectroscopy (EDX). It is observed that the shape of SiO2NPs is spherical with an average size of 8 nm, and surface charge of - 8.19 mv, which indicates that SiO2NPs is more stable.
What ’ s new at the American College of Cardiology Congress 2019 ? — New Orleans , March 16 , 2019 Co nowego na Kongresie American College of Cardiology 2019 ?

The annual American College of Cardiology congress was held in New Orleans from 16 to 18 March 2019, during which the results of numerous clinical studies that could have a significant impact on the everyday practice of cardiologists were presented. Much attention was devoted to new technologies that are changing the philosophy behind medical research — used e.g. in the Apple Heart Study. Several promising new drugs have not lived up to expectations — e.g. neladenoson in heart failure with preserved ejection fraction, while some effective therapies [e.g. TYRX antibacterial pocket reducing the risk of infection with the cardiac stimulator bed in the WRAP-IT (World-wide Randomised Antibiotic Envelope Infection Prevention Trial) study] have no chance of routine use due to their low costeffectiveness. However, in the authors’ opinion, several of the presented studies were of great importance for cardiological practice, indeed sometimes even groundbreaking importance. Below we present our subjective selection.
PREPARATION AND EVALUATION OF PIROXICAM - PLURONIC SOLID DISPERSIONS

With an objective of enhancing the dissolution rate of piroxicam (PXM), solid dispersions(SDs) of piroxicam were prepared using different grades of pluronic F-68 (Pl. F-68), pluronicF-98 (Pl. F-98), and pluronic F-127 (Pl. F-127) adopting the solvent evaporation technique.The solid dispersions were prepared at different (drug: polymer) ratio (1:1, 1:3 and 1:5). Piroxicam- pluronic solid dispersions were investigated by inferared spectroscopy (IR), x-raydiffraction (XRD) and differential scanning calorimetry (DSC). The IR spectra prevailed nochemical interaction between the drug and copolymer. The powder x-ray diffraction (XRD)patterns and differential scanning calorimetry (DSC) thermograms demonstrated thatpiroxicam was existed in a solid solution state in the SD. Phase diagram for solid dispersion ofpiroxicam in pluronic F-98 indicated that the solid solution of piroxicam was obtained at aconcentration of PXM less than 35% in the SD. The stability study was carried out for the soliddispersion prepared at 1:1 (piroxicam/ Pl. F-98) at 40 ° for 40 weeks prevailed that; the drug isstable during the storage period in the dispersion. The solubility study of piroxicam was carriedout at different concentrations of pluronics, also the dissolution rate of the drug was improvedeither by physical mixture or the solid dispersions.
THE FEMALE PHYSICAL EDUCATION TEACHER IN PRIMARY TEXTBOOKS LA MAESTRA DE EDUCACIÓN FÍSICA EN LOS

The objective of the present study is to analyse how the female physical education teacher is represented in the textbooks of this area of expertise, in the primary education stage. A quantitative study is carried out showing a high number of female teachers with regard to the male physical education teacher, mainly in the first cycle of Primary Education. Thereafter, a qualitative scrutiny was performed, through content analysis, identifying a stereotyped treatment of the physical characteristics of the teacher, by representing a teacher who is eminently young, thin, wearing sports clothes, has fair skin, and without disabilities. But, at the same time, a more open and participative image appears in relation to the role represented, since the physical education teacher can be seen in the peripheral area of the image, with an active attitude, in a space not necessarily associated with sports, without teaching complements, imparting content related to group-class management and games.
Inflation Risk Factors and Contributory Pension Wealth: Reflections on Nigeria’s Old-age Poverty

Purpose of the article: Nigeria’s shift to the Defined Contributory Scheme (DCS) is more or less questionable in terms of providing economic security for the senior citizens and preventing old age poverty. The 2004 and 2014 pension reforms sought to conform to pension theory; yet, there could be greater critical risks such as inflation risk factors. This study therefore examined how inflation risk factors impact pension wealth in Nigeria. Methods: The Structured Autoregressive Distribution Lag (ARDL) to the co-integration approach is employed to determine the relationships between inflation risk factors and investment returns of selected Nigerian pension fund administrators for the period 2009–2014. Scientific aim: This study sought the evidence to support the impact of inflation risk factors on pension wealth in Nigeria following the switch to the DCS based on the theoretical link between the investment returns and inflation rate. Findings: Inflation and world oil prices adversely affected the asset returns of pension funds management bourgeoning vulnerabilities to old age poverty. Conclusions: Pension wealth of Nigerians at the cumulating phase is at high risk to inflation risk factors, and is reasonably justified with the negative relationship with the exchange rate factors and world oil prices. The study suggests that inflation, exchange rate risk, and world oil price risk must be strategically tackled with farsighted multi-faceted fiscal and monetary measures to reduce social insecurity and vulnerability to old age poverty. The government should consider promoting the flotation of inflation-indexed bonds and urgently consider imposing a guaranteed returned pension plan (GRPP) to reduce the inflation risk in the accumulating phase of the DCS, while workers should consider increasing their contributions to mitigate inflation risk factors. Insurance life annuities can also provide inflation insurance linked to inflation-indexed bonds.
Preventing the Spread of Emerging Respiratory Infections through Vaccination, Identifying Predictive Clinical Symptoms, and Targeting Social Networks

Background : Emerging respiratory diseases can spread rapidly within closely tied, immune-naive populations through respiratory droplets and aerosols. Many have non- specific symptoms making them especially difficult to identify, differentiate and treat quickly and appropriately. Others have re-emerged as a result of changes in vaccine production and availability. Increased international trade of animals can also impact disease dynamics, making it easier for zoonotic respiratory viruses to spread to new populations. Methods : Febrile respiratory illness (FRI) and severe acute respiratory infection (SARI) surveillance data was collected among three US populations from 2011 to 2013 to evaluate clinical predictors of pathogen specific respiratory disease, seasonality and co-infection rates. Similarly, FRI surveillance at eight US military recruit training centers from 1996 to 2013 was used to assess the impact of adenovirus vaccines on respiratory disease rates. Finally, a retrospective analysis evaluated the risk of poultry avian influenza (H5N1) infection in an importing country based on the quantity of birds traded, infection in the exporting country, and their statistical interaction. Results : In the first study, clinical and demographic predictors of rhinovirus, influenza, other pathogen, and no/unknown pathogen were identified. The second study found that military trainees experienced a 100-fold decline in adenovirus disease burden during the two years after adenovirus vaccines reintroduction. Results from the third study suggest that risk of H5N1 poultry infection in an importing country increased by a factor of 1.3 (95% CI: 1.1-1.5) for every 10-fold increase in live chickens imported from countries experiencing at least one case during that year. Conclusions : Identifying demographic or clinical variables that are predictive of specific respiratory diseases is important for improving timely and accurate treatment, and recognizing the emergence of new pathogens or strains. For respiratory pathogens with existing vaccines, monitoring and evaluating vaccine benefit is important to ensure continued investment in vaccine production and prevent future disease reemergence. Additionally, limiting movement of infected animals by reducing chicken trade during H5N1 epidemic periods or increasing biosecurity measures can also reduce disease spread. Overall, prevention through early identification of cases, vaccination, and targeting transmission networks is important for preventing epidemics or pandemics of new respiratory infections
Resistance Force on a Spherical Intruder in Fluidized Bed

Insertion of large objects or intruders into granular material is common both in nature and industrial applications. During penetration due to collision between intruder and granular particles, intruder experiences resistance or drag force (analogy from fluid). In literature, it is extensively studied that in dry packed beds granular drag force increases with the intrusion depth. However, nearly no information is available about the effect of fluidization on the granular drag force and is the main theme of this paper. In this paper, discrete element method (DEM) and computational fluid dynamics (CFD) is used for performing numerical simulations. Simulations showed that granular drag force becomes independent of intrusion depth at incipient fluidization and is a function of Reynolds number. Using the mathematical relation of fluid drag force, granular viscosity of the fluidized bed is calculated. The physics for the fluid like state of granular material and the independence of granular drag force with intrusion depth is explained at the end of paper.
Influence of chitosan on hematological and histopathological changes in mice infected with Brucella melitensis immunized with Rev - 1 vaccine

This study aimed to assess the changes of blood cells constitutions and study the histopathological sections of liver and spleen in dual sexes mice infected with brucella melitensis and the role of chitosan supplement with and without Rev-1 vaccine in enhancing the inflammatory proses, two experiments were undertaken on 100 albino mice, aged 8-10 weeks for 60 days, first experiment done on 50 males and second one done on 50 females. Results of hematological analysis showed that there are significant increase at P<0.001 of white blood cells count WBC (×103), red blood cells count RBC (× 106), hematocrit (HCT), mean corpuscular value (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), lymphocyte (LY%), granulocyte (GR) and lymphocytes m/mm3 (LYM) in males treated groups comparing with females, the highest values were in immunized infected mice with chitosan diet supplement compared to infected animals. The histopathological lesions recorded there is presence of chronic inflammatory reaction characterized by mononuclear cell infiltration with presence of granulomatous lesion in the liver of immunized animals, presence of mild to moderate lesions characterized by hyperplasia of lymphoid tissue in spleen and small granulomatous lesions in liver of immunized animals fed diet with chitosan supplement.
How distance learning based on inclusion led to the proposal of a distributed access research strategy (DARS)

This article presents the results from an investigation that used a qualitative perspective of a descriptive type to identify the inclusive educational processes from 707 preschool and primary education schools in Colombia, distributed around 26 territorial units out of a total of 32. To obtain all this information around the country, a data collection strategy was applied, which we named the distributed access research strategy (DARS). All the data was collected by tertiary education students from two programs of the Faculty of Education, Corporacion Universitaria Iberoamericana in Colombia. The results revealed that most preschools and primary schools have documented institutional educational plans referencing diversity and inclusion for their students, but they have difficulties in establishing strategies to identify and implement curricular adaptations within their contexts, as well as with the use of tracking instruments. These results generated a reflection for reviewing the syllabus and study plans in the tertiary education programs at this university to better prepare future teachers who will face such scenarios in their locations across the country. Moreover, this new DARS data-collection strategy shows an interesting potential, which is generic enough to enable unlimited research topics to be explored within distance learning contexts.
Impact of Nuclear Tests on Deforestation in North Korea using Google Earth-Based Spatial Images

The North Korean government conducted its first nuclear test in 2006 and more recently the sixth nuclear test on September 3, 2017. In order to identify how North Korea's nuclear tests have affected the environment, a scientific approach is required. Although North Korea’s nuclear tests and their environmental destruction are not a severe threat to the environment of the Korean Peninsula at this time, identifying environmental damage and taking countermeasures in advance are essential to minimize their potential threats to the environments. The purpose of this study is to study the environmental impact of North Korea’s nuclear tests using Google Earth image analysis. As a method of the study, we compare Google Earth images taken before and after each nuclear test was conducted in North Korea. To overcome limitations of the suggested comparison method, we cross-checked our results with those of previous scientific research. After the 1st-3rd nuclear tests, green spaces were found to be considerably reduced. In particular, when comparing the Google Earth images before and after the second nuclear test, some ground subsidences were observed. Such subsidences can cause tunnels on the mountainsides and cracks in rocks around the mountains, leading to the release of radioactive materials and contaminating groundwater. Besides, after the 4th-6th nuclear tests, decay and deforestation were observed not in the nuclear test sites, but in their surrounding areas. Especially after the 5th and 6th nuclear tests, the topography and the forests of the surrounding areas were severely damaged. In relation to North Korea’s nuclear tests and their impact on the natural environment, we need to prepare various policy measures to reduce North Korea's environmental pollution and natural environment destruction. Those policy measures include the establishment of various cooperative governance between the Korean government, the private sector, the academia, NGOs, and international organizations.
Social Support Moderating Effect between Work-Family Conflict and Working Students’ Health and Stress in UPSI

Many studies have been done in addressing work-family conflict (WFC) among employees working in organizations. Thus, the focus of this study is to address WFC that has been faced by currently working and studying adults, and examine its relationship with their health and stress condition. In addition, this study examines the moderating effect of social support between WFC and working student’s health and stress condition. The sample for this study consists of working students enrolling in part-time programs in Universiti Pendidikan Sultan Idris, Malaysia. Questionnaires were distributed to students pursuing part-time programs in Universiti Pendidikan Sultan Idris. The questionnaire was developed based on past literature and proposed research framework. The questionnaire comprised of questions regarding WFC, stress, health, social support and demographic questions. Findings from the research indicated that WFC, faced by working students in UPSI, were significantly related to stress, health, and social support. As for the moderation effect, this study found that social support significantly moderated the relationship between WFC and working students’ stress condition, but not with health. Suggestions on actions needed to be constructed in unravelling WFC matters among working students. Policies and plans on how to mitigate WFC were suggested. Such suggestions might benefit policymakers and government in introducing relevant initiatives so that working adults’ special needs could be fulfilled, consequently reduced WFC faced by them.
