El-Haleem, N. F. A. A., S. E. - S. A. El-Aal, H. Mohammed, and S. A. Z. A. Nagdy, Obstacles Faced by Teachers in Schools of Education Property, and its Impact on their Attitudes Towards the Mentally Disabled Children, , Egypt, Cairo University, 2012. Abstractnaglaa_fathy_ahmed_abd_el-haleem.pdf

Teacher's key role in the process of teaching and learning, with him nations
progress and develop, so any difficulties facing the teacher and the obstacle
between him and the play of his duties lead to negative repercussions on the
educational process, especially if This teacher deals with children with special
needs, and especially the children who are mentally disabled because of the
difficult task awaiting the teacher education schools property. Therefore, this study
is to: 1- identify the main obstacles faced by teachers in schools of education and
intellectual Dakahliya related to: (Educational guidance, School administration,
Parents and Material resources). 2- disclose the relationship of these, obstacles
with the attitudes of teachers of schools of education intellectual Dakahliya
towards children with mental disabilities. 3- putting suggested proposal to
overcome these obstacles, which may lead to better performance of the teachers in
the schools of education property. 4- disclose the difference between teachers
according to the academic qualification as regards the obstacles that they suffer
from it. The results showed that there is no relationship between all the obstacles
(related to Educational guidance _ school management communication with
parents and material potential) and trends of intellectual education school teachers
groups to children with mental disabilities. Which indicates that the specialized
teacher in spite of the presence of all these obstacles he wants to work with
mentally disabled children.

Kamel, H. A. E. - M. A., M. M. A. Gad, and G. Mahmoud, Parental Education Philosophy and Role in Educating Pre-School Child in Light of the Directives of Quran Kareem and Sunnah of the Prophet, , Egypt, Cairo University, 2012. Abstracthanaa_abd_el-monem_atteya_kamel.pdf

The study aims at identifying the Parental education philosophy and role in
educating pre-school children in light of the directives of Quran Kareem and
sunnah of the prophet. The researcher has used the analytical descriptive method,
and the analytical critical method. The sample of the study comprised of (150)
kindergarten teachers in rural and urban areas in the Governorate of Dakahlleya,
and has also included (210) parents of the children enrolled in the rural and urban
area kindergartens in the Governorate of Dakahlleya, and has also included (70)
children, male and female in rural and urban areas in the Governorate of
Dakahlleya. The researcher used study tools, represented in (a questionnaire for all
teachers and parents, and an observation card for children).
Findings have demonstrated:
By applying T-test between the two groups of the study sample (rural and urban
children), the result came insignificant, meaning, there were no statistically
significant differences between the two groups in fulfillment of the observation
card dimensions, which means that the indicators significant of such dimensions
do not realize in rural and urban area kindergartens.

Ahmed, A. I., M. Y. S. Saif, and A. A. Zayed, Polymorphisms of DNA repair genes and sun exposure as predisposing factors for age related cataract, , vol. 21, 2012. Abstractcu_pdf.pdf

Age-related cataract is a leading cause of
blindness throughout the world. Regular exposure to
sunlight increases the risk of cataract development. Ultraviolet
light causes oxidative stress which induces DNA
damage in the lens epithelium and the development of
opacities. The existence of DNA repair in lens epithelial
cells has been reported, and polymorphisms of DNA repair
genes may affect repair efficiency. This work aims to study
the frequency of polymorphisms of two DNA repair genes,
xeroderma pigmentosum complementation group D (XPD)
codon751 and X-ray cross-complementing group 1
(XRCC1) codon399, in cataract in the sunny weather of
Egypt. Forty-two Egyptian patients with maturity onset
cataract were compared to 41 control subjects using
polymerase chain reaction and restriction fragment length
polymorphism. There was a significant increase in frequency
of XRCC1-399 Arg/Arg genotype in cataract patients
(42.8%) compared to healthy controls (22%) (p=0.042).
This increase remained significant after redistribution
according to occupational exposure. No significant difference
was found for the genotypic and allelic distributions of
the polymorphisms in XPD-751 gene (p>0.05) between
groups. There was a significant increase in cataract
development in subjects with high exposure risk to sunlight
more than those with low risk, either due to their
occupation (p=0.034) or to residence in sunny areas of
upper Egypt (p=0.037). Findings suggest that polymorphism
in XRCC1 codon399 may predispose to the
development of maturity-onset cataract and support the
hypothesis that sun exposure is a leading factor for cataract

Nassar, N. N., R. M. Abdelsalam, A. A. Abdel-Rahman, and D. M. Abdallah, "Possible Involvement of Oxidative Stress and Inflammatory Mediators in the Protective Effects of the Early Preconditioning Window Against Transient Global Ischemia in Rats", Neurochemical Research, vol. 37, 2012. Abstractcu_pdf.pdf

Ischemic preconditioning (IPC), comprising exposure to sub-lethal short term ischemic events, has been shown to exert adaptive responses in many organs including the brain, thus guarding against exacerbations of ischemia reperfusion (IR). However, the mechanisms involved in the early phase of such a protection remain elusive; hence, the present study aimed to investigate the modulatory effect of preconditioning against IR induced injury on infarct size, free radicals, inflammatory/anti-inflammatory markers, caspase-3 and heat shock protein (HSP)70 in the rat hippocampus. To this end, male Wistar rats were divided into 3 groups, (1) sham operated (SO) control; (2) IPC, animals were subject to 3 episodes of ischemia (5 min) followed by reperfusion (10 min), afterwards rats underwent ischemia (15 min) followed by reperfusion (60 min); (3) IR animals were subjected to 15 min global ischemia followed by 60 min reperfusion.IR produced cerebral infarction accompanied by an imbalance in the hippocampal redox status, neutrophil infiltration, elevation in tumor necrosis factor (TNF)-a and prostaglandin (PG)E2, besides reduction in interleukin (IL)-10 and nitric oxide (NO) levels. IPC reverted all changes except for PGE2; however, neither HSP70 norcaspase-3 expression was altered following IR or IPC. The current study points thus towards the activation of the antioxidant system, anti-inflammatory pathway, as well as NO in the early phase of preconditioning protection.

Background And Objective: It has been known that the expression levels
GST were correlated with tumorigenesis and prognosis. The aim of this study is to
investigate the relationship between expression levels of GST in tissue &serum
level, and clinicopathologic parameters, survival &response to platinum
containing regimen used in treatment of patients with lung cancer. Methods: The
expression levels of GST were detected by immunohistochemical staining on
tissue micro-array sections made of 64 cases of lung cancer and serum samples
were collected from 68 cases pre-treatment, post 2nd Cycle & post 4th as such.10
control cases serum samples were also examined. The results were compared with
relevant clinical and pathologic data. Results: There were 50 males (73.6%) and
18 females (26.4%), their ages ranged from 30 to 69 years with a median of 55
years. The pathology included 24 patients had squamous cell carcinoma and 44
non squamous cell carcinomas. PS was I in 36 (52.9%) cases while PS was II in
the remaining 32 cases (47.1%). Sixty cases were presented with either stage IIIB
or IV. Serum samples pre-treatment could express tissue expression of GST
(P<0.001). We also found that GST in serum rose markedly in progressive disease
compared to minor rise in stable disease in post 2nd & 4th cycle samples compared
to pre-treatment level, while it decreased in disease responding cases (PR) p<0.001
and 0.015 consecutively. A strong correlation between early& late stages disease
and both OS (p=0.03) & PFS (p= 0.003) was found. There were no significant
correlations between tissue expression of GST and either overall survival (P =
0.66) nor progression free survival. (P =0.34), same as serum GST pre-treatment
level (p= 0.68 & 0.106). Multivariate analysis using Cox regression model showed
that expression levels of GST & serum level pretreatment were not the important
independent prognostic factors for survival. Conclusion: Serum GST pretreatment
level in non small cell lung cancer could predict tissue expression of GST.
Changes in this level, whether rising or declining, could predict response to
platinum containing regimen.

El-Kashef, H. A. E. - S. S. A., A. M. A. El-Fattah, and F. Hassan, Properties, Preservation and Evaluation of Buffaloes’ and Cows’ Colostrum, , Egypt, Cairo University, 2012. Abstracthany_abd_el-satar_a._sadek_el-kashef.pdf

This study was designed to follow the changes in properties of Egyptian
buffalo and Holstein cow colostrum after parturition, select the proper heat
treatment of buffalo and cow colostrum that would produce no significant
changes in viscosity and IgG concentration, compare between freezing and
freeze-drying methods for colostrum preservation and evaluate the safety of
long-term consumption of Egyptian buffalo or Holstein cow colostrum on
young Wistar rats. The obtained results illustrated that at calving, buffalo
colostrum was characterized by significantly higher fat, lactose, ash, total
solids, phosphorus, vitamin E, Val, Met, Ile, Phe, His, Lys, Asp, Pro, Cys,
Tyr and IGF-1 as well as viscosity; and significantly lower Mg, Na, K, Zn,
vitamin A, Ser, Glu, Gly, Ala, Arg and lactoferrin concentrations compared
to cow colostrum. Also, data obtained showed that as the lactation period
advanced, the levels of total protein, whey proteins, fat, ash, total solids,
bioactive components (IgG, IgM, IGF-1 and lactoferrin), specific gravity,
viscosity and titratable acidity in both colostrums decreased and those of
lactose and pH conversely increased. As for essential and non-essential
amino acids, macro- and micro elements, and vitamins A and E, data
obtained showed some significant and non-significant changes in both
colostrums during the first 5 days and after 14 days of parturition.
Comparing with cow milk, buffalo milk had significantly higher fat, total
solids, Ca, Mg, vitamin E, Ile, Phe, His, Lys, Cys, Tyr; and significantly
lower Na, P, Cu, Zn, vitamin A, Leu, Asp, Gly and Ala concentrations on
the fifth day of parturition. Heat treatment of buffalo and cow colostrum at
60°C/60 min could be sufficient to eliminate pathogens (Staphylococcus
aureus, Salmonella spp. and Escherichia coli( and maintained colostral IgG

and fluid characteristics. Freeze-drying had no effect on the colostrum bioactive
substances. The bioactive substances of frozen or freeze-dried colostrum
decreased gradually during the six months of storage. The greatest influence of the
storage was found on the concentration of IgM. The present study revealed that at
the end of the experimental period (90 days), there was no difference between
buffalo or cow colostrum-fed animals at dose of 0.5 ml /100g body weight of rat
and the control group in clinical signs, hematology, most parameters of blood
chemistry (carbohydrate metabolism, liver and kidney functions) and histological
structure of liver, kidney and duodenum.

Amal I., K., and H. M. Bayoumy, Psychological Motives and Vulnerability for Pulmonary Dysfunction among Tobacco Smokers, , vol. 7, issue 8, 2012. Abstractcu_pdf.pdf

Tobacco smoking has multidimensional motives which might lead to compulsive or problematic nicotine use. Pulmonary diseases associated with tobacco smoking are a complex group of disorders the early diagnosis of which as well as identification of motives behind smoking would allow effective management. Therefore, the aim of the present study was to assess motives that influence smokers’ decision to use tobacco, the impact on pulmonary function and possible associations among those outcomes as well as with related background characteristics of study participants. METHODS: Participants in this descriptive correlational study comprised of 96 smokers. Majority was students, with average age of 22.01±5.87 years. Age, weight, height, BMI and pack-years were recorded, smoking dependence motives were assessed and spirometry was performed. RESULTS: Smoking dependence motives revealed equivocal mean ranged between (2.5 – 2.8) with increasing mean value of nicotine dependence motives. Mean tobacco consumption was 9.80 ± 10.82 pack-years. Study participants exhibited mild airflow limitation, mean percentage of predicted values for FEV1 was 83% ± 0.9, mean FVC was 4.6 ± 1.3, and FEV1/FVC ratio was as low as 45% ± 1.2. Psychological motives had shown weak correlations with FEV1, FVC and PEF. Certain motives however, showed significant differences with number of cigarettes smoked per day. Age at start of smoking as well as intensity of smoking showed significant relation with FEV1 decline. CONCLUSIONS: Smokers had shown mild airflow limitation. Various smoking motives affected study participants equally. The implementation of a coordinated tobacco control program is therefore required.

study including fifty consecutive patients with colorectal cancer treated surgically
during the period from the r of November 2011 till the is" of May 2012. Patients
were randomized into 2 groups; group A managed according to the ERAS protocol
and group B managed according to the conventional perioperative management for
patients undergoing colorectal surgery. Results: The results of our study have
shown significant advantages of fast track protocol; however, strong evidence is
forthcoming through a larger study over a larger number ofpatients. Conclusion:
This study concluded that the ERAS protocol is potentially applicable in the
National Cancer Institute, Cairo University.

Morsy, E. S. M., S. Salah, and M. Iraqy, The Sentence Structure System and its Role in the Cohesion of the Text in the Poetry of Ibn El Fared, , Egypt, Cairo University, 2012. Abstractehab_saud_mohammad_morsy.pdf

This research is titled [the sentence structure system and its role in the cohesion
of the text in the poetry of Ibn El fared] subject revolves around two issues: first to
specifically include the installation of different patterns in the poetry of Ibn El
fared; to detect the most important structural properties that Inmaz by his hair. The
second; is represented in the statement of the impact of the structural coherence of
the sentence in the text. Thus, the ultimate goal of this research is to study the
structural system of the phrase in the poetry of Ibn El fared; to try to detect the
contribution of the structural coherence in the text. And the poetry of Ibn El fared
just a practical model; that is not taught to the same as what was taught to
strengthen the idea of theory in research; Valmqarbh text of the research can be
applied to any other provision, whether text, poetry or prose; but the results will be
different depending on the type of text, depending on the style product text.

El-Aziz, N. A. A. A., M. M. Stino, and A. E. Zafrany, Spatial Poverty Map as a Guide for Regional Development Policies, , Egypt, Cairo University, 2012. Abstractnoha_ahmed_ahmed_abd_el-aziz.pdf

This research examines the relationship between urban parks and the quality of
life (QoL). It aims at investigating both positive and negative impacts of urban
parks on the quality of life of the city dwellers. To fulfill this aim, a theoretical
framework is produced encompassing design and management criteria covering
social, environmental, and economic goals. Afterwards, four case studies (El
Azhar Park, El Dowlia Park, El Thakfia Park, and Rod El Farag Park) are chosen
to test the theoretical framework in the Egyptian context . The results indicate that
the current provision of local parks (with one function) is under-utilized and
unable to attract and satisfy local dwellers. Design and management problems
make of those parks a burden for the city economy. However, the research finds
that regional park performance is better in providing significant QoL variables to
the park users and the non-users in the adjacent neighbourhoods. Moreover,
disparities are found among the perceptions of low, medium and high income
users towards what affect the quality of their lives and what their preferences and
priorities are. The research is concluded with recommendations regarding the
planning, designing and managing guidelines for urban parks in Cairo city, with
respect to the park accessibility (level of service) and the target users’ socioeconomic
classes. Local recommendations targeting case studies to improve their
efficiency and future research topics are suggested.

El-Kader, E. A. A., T. M. Labib, A. M. Sharaky, G. I. El-Diwani, and S. I. Hawash, Study of Heterogeneous Catalysed Transesterification Reaction for the Production of Bioenergy (Biodiesel) From Jatropha Oil in Africa, , Egypt, Cairo University, 2012. Abstractelham_ahmed_abd_el-kader.pdf

This work focuses on the development of using heterogeneous catalysts for
biodiesel production from nonedible vegetable oil (Jatropha curcas oil, JCO) with
moderate free fatty acid content (3%). Solid-base catalyst as (CaO) and acid
catalyst as (S-ZrO2) were prepared. The ability of CaO as a potential
heterogeneous catalyst was investigated in broad range while acid catalyst (SZrO2)
was also tested for single step simultaneous esterification and
transesterification. Transesterification of JCO using CaO as solid super base
catalyst was studied under mild conditions, through bench scale experimental
work. Effect of molar ratio of methanol to oil, reaction time, mass ratio of catalyst
to oil were investigated while transesterification using subcritical methanolysis has
been studied under different conditions of temperature (from 120 to 250°C),
pressure (from 6 to 37 bars) and time (from 10 to 60 min.) using super base CaO.
Two different weights of acid catalyst (S-ZrO2) were studied at temperature
(120°C). The reaction products were tested for their content of biodiesel and purity
of glycerol using High Performance Liquid Chromatography (HPLC) technique.
Results of catalyst CaO preparation concluded that: increasing the calcination
temperature of CaO to 900ºC (up to decomposition temperature of CaCO3) after
dipping in ammonium carbonate increases the basicity of the catalyst which is an
important property for catalyst activity in the transesterification reaction.
Experimental results at atmospheric pressure.

This study aimed at assesses the teachers' concept and its relation to temperament and coping strategies among mentally retarded children. A descriptive correlational design was utilized in this study. convenient sample consisted of 130 mentally retarded children, their parents and 31 teachers was selected; who were presented at the schools of El- Tarbia- El- Fekria in Hahia and Zagazig city. Tools for data collection were-, Socio-demographic data sheet, the teachers' Temperament Questionnaire (TTQ), the teachers' concept of the mental retardation, and The Coping Ability in Children. The results reveald that Temperament increased with increasing coping abilities, Children coping score had positive significant correlations with children IQ, No statistically significant associations between teachers' concept and coping and temperament. It was concluded that when IQ of those children was high, the coping abilities increased. The study recommended that the teachers should continuously observe and evaluate the children to recognize the temperament and coping abilities in the class. Building positive relationship and deal with children by love, sympathy, empathy and caring.

El-Saiad, K. A. A. E. - B. A., Theory of Right in 'Ilm Usūl Al-fiqh, A Study in the Islamic Methodology, , Egypt, Cairo University, 2012. Abstractkareem_ahmed_abd_el-baky_aly_el-saiad.pdf

This research studied Theory of Right in 'Ilm Usūl Al-fiqh which is considered
as the methodological traditional Islamic science. It concentrated on the concept of
right of traditional Muslim scholars ('Ulamaa') of fundamentals of comprehension
('Ilm Usūl Al-fiqh), from Al Shafi'i (died 204 AH) to our days and on the question
of human rights in the context of Islamic legal thought. The research used several
methods: The historical method in the first part, the structural method in the
second part and the comparative method also in the second part. Two parts
formed the main body of this research; each of them had three chapters and a
conclusion, in addition to an introduction and a final conclusion. The
introduction exposed the main question of the research, methods used within it
and a critical revision to certain related studies of the most important ones under
the topic of human rights in Islam. The first part: "Evolution of Theory of Right"
was devoted to the historical pursuing of theory of right in 'Ilm Usūl Al-Fiqh. It
consisted of three chapters; the first of them explained the way in which the
historical method here was used . The second was the very pursuing of the
historical evolution of the theory. The third studied the curve of the historical
evolution of the theory, and the historical, theoretical and systemic factors which
affected that curve. The second part: "Structure of Theory of Right" was devoted
to the study of the structure of the theory. Its first chapter exposed the way of
using the method and the forms of the structure of the theory throughout its
history. Its second chapter was the anatomy of the structure in four levels different
in depth. The third chapter exposed the conclusion from the anatomy of the
structure and studied the nature of right and law in 'Ilm Usūl Al-fiqh
comparatively with certain western systems of legal philosophy, like of Kant,
Jeremy Bentham, John Austin and others.
