Depiction of Women in the Media: Examining the Effect of
Portrayals on Education

Abstract:
Undoubtedly, women around the world both deserve and need a
positive portrayal in the media. This includes television
programs, commercials, newspaper articles, other forms of print
media and radio. The growing influence of social media provides
another critical avenue for women to promote the importance of
providing access to all area of society. The economic benefit of
including women in traditionally male-dominated careers is
another reason to embrace this change. By harnessing media to
promote a gender-positive message in which women are capable of
anything in society, rates of discrimination will likely
decrease. Perhaps most importantly, rates of both physical and
sexual violence will also be reduced following attitudinal
change.

Abstract: Introduction:
The most common side effects associated with the use of
methotrexate (MTX) in the commonly used doses is hepatic
toxicity. As a herbal alternative Hordeumvulgare seeds
(Commonly known as Barley) commonly used by traditional medical
practitioners in the treatment of many diseases including liver
diseases. Aim of the work: The aim of this study was to
study the potential protective effect of Barley's grains on MTX
induced liver injury. Materials and methods:
adult male rats were used.
The animals were divided into three groups each of them consists
of 10 rats:
Group I: (control group): were
injected with IP saline. Group II: were IP injected with MTX in
a dose of 6mg/kg /day for 5 days. Group III:
Barley grains were given at a
dose of 200g /kg/day for 30 days plusintraperitoneal injections
of MTX on the day 25, at the dose 6mg/kg /day for 5 days.
the rats were sacrificed
by decapitation then liver pieces
for light microscopic study were obtained. Results: MTX
markedly affected the liver tissue as appeared by light
microscopic, immunohistochemical examinations and morphometric
studies. Pretreatment of Barley's grains could attenuate some of
these changes. Conclusion: Pretreatment of Barley's
grains had a possible protective effect against MTX induced
liver injury.

Provisional Prosthetic Nasal
Rehabilitation following Total Rhinectomy Using a Silicone Based
Prosthesis
Yasser Araby

dr.yasser.araby@qudent.edu.sa
Abstract:
Tumors of the nasal skin are
common, and can usually be managed with local excision and
reconstruction or radiotherapy. Extensive, neglected or
recurrent nasal tumors may require rhinectomy for complete
excision. Surgical reconstruction of the rhinectomy defect is
challenging. Attempts at autologous reconstruction with regional
flaps or free tissue transfer are frequently unsatisfactory,
even in the hands of the most skilled surgeon. A good prosthesis
is invariably better than the best reconstruction.
The literature indicates
that 3 to 5 months of postoperative healing may be required to
allow for contraction and organization of the tissue bed before
commencing fabrication of a definitive nasal prosthesis. This
delay in rehabilitation can be a hardship for the patient and
result in adverse psychological consequences. Early
rehabilitation through the use of a temporary nasal prosthesis
offers a means of overcoming these difficulties.
The purpose of this
article is to present a clinical report that describes the
provisional prosthetic rehabilitation using a silicone based
prosthesis of a patient who had undergone a total rhinectomy as
a result of a neglected basal cell carcinoma of the nose to
fulfill the esthetic requirements of the patient and allow him
to practice his social activities confidently.

Abstract:
Toxicity of some insecticides (Azadirachtin, Imidacloprid and
Methoxyfenozide) were tested on the foragers honeybee
Apismelliferajemenatica, under laboratory conditions. All
these three insecticides were used at the same concentrations:
0.5, 2.5, 7.5 and 10 ppm and control group (0 ppm) and comparing
the mix of the three insecticides. Assessments were made after
1,2,3,4,5,6,8,12,24,48,72 and 96 hours after treatment. There
were differences in foragers honeybee workers mortality between
the control and all insecticides treatments, also mortality
differences were found among the various treatments were the
most dangerous insecticides after 48 h. is the Imidacloprid
whose mortality rate was the highest reaching to 100% at 7.5 and
10 ppm. At 0.5 ppm, Azadirachtin and Methoxyfenozide had the
lowest mortality rate. Foragers honeybee workers mortality
increased with time after treatment. Anyway, at 7.5 ppm, the LT50=
2.714, 5.061, 7.052 and 8.687 hours in Imidacloprid, Mix,
Methoxyfenozide and Azadirachtin, respectively. The control
group (Control) showed the longest age of the honey bee workers
having an LT50 = 1749.421 hours. These findings
indicate that Imidacloprid then Methoxyfenozide greatly affect
forager honeybees workers, whereas Azadirachtin was less
effective because it was associated with lower death rate and a
longer life span seen with the honeybees workers. In conclusion,
the present study clearly showed that these were the most
effective insecticides at the rate each was tested.

Abstract:
Sicklecell anemia (SCA)
primarily affects people with African, Mediterranean, South
American, Middle Eastern, and Indian ancestry.
Sickle cell disease is an
inherited hemoglobinopathy that develops from a genetic mutation
and the production of a dysfunctional variant of hemoglobin. A
number of physiological disturbances encountered during the
perioperative period (blood loss, hypotension, acidosis, and
hypoxia) may induce "sickling" of the biochemically altered
hemoglobin, producing painful microvascular occlusion, hemolytic
anemia, and impaired oxygen delivery. The only available
curative therapy requires bone marrow transplantation. The
purpose of this article is to review the pathophysiology of
sickle cell disease and the pertinent preoperative,
intraoperative, and postoperative care of patients with the
disease. Persons with sickle cell anemia are more likely
to undergo surgery than are the general population during their
lifetime. As surgery exposes patients to many of the factors
that are known to precipitate red blood cell sickling, persons
with SCD undergoing surgery require specific clinical care to
prevent peri-operative sickle cellrelated complications.

Abstract:
Three upper Campanian- upper Maastrichtian exposures on the
western flank of Esh El-Mellaha range, north Eastern Desert,
Egypt from north to south: Wadi Dib, Wadi Abu Had, and Bir
Mellaha sections are studied. This interval is represented by
the Sudr Formation which is classified into Markha and Abu
Zeneima members from base to top. This rock unit is found very
rich in planktonic foraminiferal assemblages. Fifty seven
planktonic foraminiferal species belonging to seventeen genera,
six subfamilies, five families, four superfamilies and one
suborder are recorded and most of them are belonging to family "Globotruncanidae”
where it includes eleven genera and thirty eight species. So,
the phylogenetic development of the recorded species and genera
from this important family is discussed. Eleven planktonic
foraminiferal biozones are distinguished in the studied
sequence; one of late early Campanian to late Campanian age (Globotruncana
ventricosa Zone); two of late Campanian age (Globotruncanella
havanensis (=CF9) and Globotruncana aegyptiaca (CF8a)
zones); four of early Maastrichtian age (Rugoglobigerina
hexacamerata (CF8b), Gansserina gansseri (CF7),
Contusotruncana contusa (CF6), Pseudotextularia
intermedia (CF5) zones); and for the first time four of late
Maastrichtian age (Racemiguembelina fructicosa (CF4),
Pseudoguembelina hariaensis (CF3), Pseudoguembelina
palpebera (CF2), and Plummerita hantkeninoides
(CF1) zones). The Campanian / Maastrichtian boundary is located
within the lower part of the Abu Zeneima Member between (CF8a)
and (CF8b) zones, while the early / late Maastrichtian boundary
is located within the upper part of the Abu Zeneima Member
between (CF5) and (CF4) zones. Two unconformity surfaces are
recorded within the Sudr Formation. The first one is recorded at
the three studied sections and it lies between the Markha and
Abu Zeneima Members due to absence of the late Campanian
Globotruncanita calcarata Zone; while the second
unconformity surface is recorded at both Wadi Abu Had and Wadi
Dib sections only and it lies within the uppermost part of Abu
Zeneima Member due to absence of the last two latest
Maastrichtian CF2 and CF1 zones.

Abstract:
Gastric tuberculosis is an uncommon site of extra-pulmonary
tuberculosis infection; clinically gastric tuberculosis
resembles peptic ulcer disease or less likely a gastric
malignant growth. We report a case of an endoscopic large
gastric mass in an HIV negative immunocompetent male patient
secondary to pulmonary tuberculosis presented with severe
chronic abdominal pain and vomiting found to have a large
tuberculoma at the fundus of the stomach, follow up endoscopy
after 12 month of antituberculous treatment showed remnants of
fibrotic bands with complete recovery of the patient from his
pulmonary as well as the extra pulmonary gastric TB.
This case report highlight the utility of endoscopic brush
smears in the diagnosis of tuberculosis in clinically suspected
cases and necessity of application of Z-N stain smear on
endoscopic brush cytology as a
reliable and simple modality for the diagnosis of gastric
tuberculosis.

Abstract:
Purine can
be considered as the most ubiquitous and functional
N-heterocyclic compounds in nature. Structural modifications of
natural purines, particularly using isosteric ring systems, have
been in the focus of many drug discovery programs. Due to the
structural similarity between the pyrazolo[1,5-a] [1,3,5]
triazine scaffold and the purine system, modifications of this
scaffold have given rise to a lot of bioactive agents which
could interact with targets of biogenic purines. The present
review to the best of our knowledge about synthesis of
pyrazolo[1,5-a] [1,3,5] triazine scaffold as enzyme
inhibitors with therapeutic value.

Integrated Channel
Maintenance with Stakeholders Participation (Case Study)
Tarek G. El Din Ahmed, Salwa M.
Abou El Ella and Tarek A. El Samman
Abstract:
Participation of water user associations (WUAs) is considered
the key factor contributing to the long term maintenance
sustainability of branch open irrigation channels. Therefore,
this paper describes a new experience and study of management
program for sustainable branch canals maintenance through
involvement of water users and stakeholders (irrigation
officials and beneficiaries). The principal study of the project
is to situate and examine a comprehensive open waterways
maintenance strategy that incorporates technical civil works
with related social activities that consider social dimensions
of water users. This strategy aims to guarantee maintenance
process sustainability while in parallel provide social
activities for farm organic residuals elimination and conversion
into compost and biogas; that consequently would reduce farm
expenses and enhance life style. The study was implemented in
four branch canals that cover four different regions in Egypt.
The implemented integrated channel maintenance program comprised
of three principal directions; (1) branch canal rehabilitation
(2) aquatic weeds management and (3) increase public awareness
with capacity building of water user association members. The
general impression regarding the experience of teaming up
beneficiaries with irrigation officials was highly satisfactory;
as the experiment could create case of excellent communication
and understanding regarding beneficiaries’ demands and
irrigation directorates’ facilities. Accordingly maintenance
efforts could be managed and planned more clearly and
effectively. Partial rehabilitation of open channel result in
satisfactory hydraulic performance enhancement with reasonably
reduced cost. Moreover general recommended guidelines/strategy
for developing open channel maintenance are included the paper.

Abstract:
Various cases of accessory
leaflets of mitral valve or tissue around the opening have been
reported in the past. In some cases they were the main
etiological factor for sub aortic stenosis or regurgitation.
Here we report a rare finding of accessory posterolateral cusp
of mitral valve with accessory papillary muscle in left
ventricle of an adult male cadaver. Such variation has not been
reported earlier in our region. We noticed additional commissure
(as deep as rest of the other two) with chordae tendonae
attached from the tip of additional papillary muscle. Such
Variations may cause regurgitation or may compress outflow tract
causing stenosis which may require their immediate removal.
Awareness of such variations on the part of the surgical team is
extremely important before operating in cases of mitral valve
prolapse or regurgitation, aortic or mitral stenosis and left
ventricular outflow tract obstruction and various valvular
repair and graft surgeries. Knowledge of these would help in
proper designing and placement of valve prosthesis.

E-mail:
amerafahmy16@yahoo.com
Abstract: Introduction:
AflatoxinB1 (AFB1) is considered the most potent mycotoxins. When
AFB1 is administrated through contaminated food causes severe
kidney damage. curcumin and garlic have antioxidants effects and
may be effective in ameliorating the toxic effects of AFB1.
Aim: This work was carried out to study the histological
changes in AFB1-induced toxicity in the kidney and the possible
protective role of curcumin and garlic in adult male guinea
pigs. Material & Methods: In this study, sixty adult male
guinea pigs were used. They were divided into six groups (10
rats for each): group
I (control), group II (curcumin treated group), group III (garlic
treated group), group IV (AFB1 treated group), group
V (AFB1 and curcumin
treated group) and group VI (AFB1 and garlic treated group).
Kidney specimens were obtained at the end and processed.
Results: Light studies showed degenerative changes; most
glomeruli showed marked distorsion, some glomeruli were
enlarged, other glomeruli were segmented and atrophied. The
renal tubules showed marked degenerative changes. There were
hyaline material deposition, dilated congested blood vessels and
mononuclear cellular infilteration. Curcumin and garlic
treatment decreased the toxic effects of AFB1. Garlic
administration showed higher protection against AFB1 toxicity.
Conclusion: It was concluded that, the garlic has a
better protective effect than curcumin against toxic effect of
AFB1.

Abstract: Background:
Aortic graft infection (AGI) historically has been treated with
extraanatomical bypass, graft excision, and aortic stump
closure, with very high mortality and amputation rates. In-situ
reconstruction is alternatives to this strategy. This study
demonstrates our experience in 12 patients with aortic graft
infection, treated by graft excision and in-situ aortobiofemoral
reconstruction using the femoral vein. Methods: During 5
years, all patients with AGI or aortic mycotic aneurysm and have
an adequate FPVs were prospectively selected for NAIS procedure.
Results:
The mean ASA score was 3 ± 1, mean operative time was 5.3± 2.1
hours. One patient died postoperative due to MI. The mean
follow-up was 16 months. No evidence of reinfection in all
patients.
Conclusions:
Using FPV in pantaloon configuration for AGI treatment is an
excellent conduit which is resistant to infection.

Abstract: Background:
Nutmeg is a popular
spice
& flavor
that has a long list of associated health
benefits.
It is the shelled, dried seed of the plant Myristica fragrans.
Nutmeg is used for treatment of diarrhea, nausea, stomach spasms
and pain, and intestinal gas. It is also used for treating
cancer,
kidney
disease,
and
trouble sleeping
(insomnia).
Nutmeg is widely used for increasing menstrual flow, causing a
miscarriage.
Because it contains chemicals that affect central nervous
system, many people used it as a hallucinogen and as a general
tonic. Side effects such as thirst, dizziness, nausea, vomiting,
feelings of pressure in the chest or stomach, dry mouth, stomach
pain, and many other problems might occur in some people. Large
dosage can be toxic, producing disorientation, double vision and
convulsions, and even death.
Objectives:
Evaluating the role of Tumor Necrosis Factor- alpha (TNF-alpha)
and Interleukin- 6 (IL-6) in Nutmeg Induced Pulmonary Injury in
adult albino rats.
Material and Methods:
Adult male albino rats (n=40) were used & classified into two
groups: Group I (n= 20) served as control& group II (n= 20)
treated with nutmeg in a dose of 500mg/kg orally daily for 12
weeks (1/10 LD50). At the time of sacrifice, the
lungs were dissected and tissue samples were processed for light
microscopic & molecular studies. Histological (haematoxylin and
eosin, Toluidine blue & Masson trichrome stains) and
immunohistochemical studies (CD68 to show alveolar macrophages)
were done. Morphometric study was also done for septal alveolar
wall thickness and number of alveolar macrophages. The mRNA
expression of TNF-alpha and IL-6 in the lung tissue was
quantified by competitive RT-PCR.
Results:
Administration of nutmeg markedly disrupted the normal
architecture in the form of thickening of inter-alveolar septa,
over expansion of alveoli, congestion of blood vessels, cellular
infiltration, proliferation and vacuolation of pneumocytes type
II. Increase in TNF-alpha and IL-6 levels was also noticed.
Conclusion:
It could be concluded that prolonged administration of nutmeg in
rats can induce lung damage with possible role of both TNF-alpha
and IL-6 cytokines for further studies.

Abstract:
Nanoparticles are a promising evolution in this era. Toxicities
of nanoparticles are not well known yet. Quantum dots (QDs) are
nanoparticles that could be used in biomedical field. Quantum
dots containing cadmium are good semiconductors and could play
an important role for biomedical applications. In vivo toxicity
studies are still not sufficient to evaluate Cd containing QDs
for biomedical applications. Two types of ‘aqueous QDs included
CdSe/ZnS and CdTe, with green emission color and 520-550
emission peak, were used. Acute toxicity was studied by
injecting single mounting high doses “5, 50, 500 µg/ kg”
intravenously in the tails of mice and samples were collected 14
days after injection. Cadmium “Cd”, selenium “Se”, and tellurium
“Te” levels were measured in animals’ blood using Energy
Dispersive X-ray Fluorescence (EDXRF), a highly sensitive
multi-elemental method of micro-analysis. Complete blood
picture, liver function and kidney function tests were measured.
Histopathological examination was performed for samples from the
liver, kidney, lung, spleen and heart. Heavy metals were
distributed to all of the studied organs with higher levels than
the control group. Intravenous cadmium nanoparticles were
distributed to all organs including the lung. Cadmium could
cause lung toxicity due to the developed chemical pneumonitis.
Tellurium containing QD could be more nephrotoxic. The results
revealed variant degrees of pathological changes in the organs
and elevated normal levels of the laboratory investigations. The
studied QDs were unstable in vivo and were still existed
in the body 14 days following intravenous administration. No
dose related toxicity was noticed. Histopathological changes
could be reversible and could not hinder the use of the studied
QDs for biomedical applications. Further studies are recommended
for longer period for detection of excretion time and long
sequel toxicity, and for evaluation of the QDs stability few
hours after injection to assess its in vivo usage.

Abstract:
Productivity and earliness of pea population (Barl
X Protor), under late
sowing date (5th December), were studied for some
quantitative characters via selection. Four field experiments
were conducted at the
Experimental farm of Faculty of Agriculture South Valley
University, Qena Governorate, during the four winter seasons
(2012/2013 – 2015/2016). Highly significant was detected among
generations (F3, F4 and F5),
for all investigated traits. The generations were earlier than
the base population (F2) by 5.7, 8.5 and 9.5 days
respectively, and earlier by 3.5 and 5.5 days for average two
parents and check cultivar compared to F5 generation.
Dry seed yield/plant, green seed yield/plant, number of
pods/plant, weight of 100-dry seeds, weight of 100-green seeds,
shell – out %, number of seeds/pod and pod length traits were
increased by 64.15%, 42.8%, 29.14%, 44.33%, 17.65%, 17.65,
10.25% and 2.12%, respectively. In the F5 generations
as compared to F2, percentage of response to
selection of the mid-parent showed values of -4, 84, -4.05 and
-6.41 in the F3, F4 and F5
populations, and it was value of -8.81, -11.25 and – 9.94 in F3,
F4 and F5 generations as percentage of the
check cultivar in NDF trait. Slightly differences were observed
between PCV% and GCV% in all populations for all studied traits.
Estimates of broad sense heritability value ranged from 36.41%
in the F4 populations for NS trait to 99.85% in F5
population for 100-WGS. These results indicating the importance
of the genetic effects in controlling the inheritance of all
traits compared to the environmental conditions. the genetic
variation and broad sense heritability were high for number of
days to flowering and green seed yield/plant in F3 generation,
the genetic improvement could be by selection.
