Abstract:
The Eastern Nile River Basin is currently experiencing new
developments of 13 dams and reservoirs; both in Ethiopia and in
Sudan to full utilize the basin for electricity generating and
irrigation to face the population growth. These dams are 5 dams
(Gambella, Baro1, Baro 2, Geba A and GebaR) on Baro-Akobo-
Sobat-White Nile, 3 dams (Metema Dam, Rumela Dam and Humera Dam)
on Tekeze-Setit-Atbara and 4 dams (Mandaya, Karadopi, Beko Abo
and Grand Ethiopian Renaissance Dam) on Blue Nile and one dam
(Kajbar Dam) on Main Nile. Egypt and Sudan are hot arid and
semiarid countries, almost vitally relying on the Nile water as
water source, with water demand in Egypt alone set to increase.
These developments will strongly affect the water flow at Aswan.
Therefore, it is needed to take into account these developments
for Egyptian water right. In addition, the impacts of climate
change for the whole basin development and management for near
future (2011-2040), intermediate future (2041 – 2070) and far
future (2071 – 2100) on the inflow, evaporation and energy
production at High Aswan Dam have been taken into consideration.
RIBASIM Model has been used in this study to simulate the water
system in the Eastern Nile Basin. The model has advanced
flexible features in operating goals for several different types
of demand (hydro-power, irrigation, etc.) and the option to
manage the system with priority to different demands. The
baseline models is configured with the existing infrastructure
and calibrated with historical hydrological regime. The model
performed very well and satisfactory simulates the monthly flow
distribution. The Nash-Sutcliffe efficiency and coefficient of
determination accuracy were 0.95 for most of the gauge stations,
Where, Mean Relative Bias (PBAIS) and Root Mean Square error
(RMSE) varies between 0.015-28, 29-555m3/s,
respectively. 32 scenarios have been considered to assess the
impacts of climate change on the Eastern Nile River. These
scenarios comprise baseline scenario, 14 development scenarios,
18 combined / management scenarios (17 individual covering basin
and 1 overall basin) during the current century and 4 climate
change scenarios 2011–2040 (near future), 2041-2070
(intermediate future) and 2071-2100 (far future), respectively.
10 dams out of the 13 have a negative impact to the inflow at
Aswan, The development and management of 10 dams on the Eastern
Nile would reduce average annual the inflow, evaporation and
energy production at Lake Nasser/ HAD by 18%, 4% and 4%,
respectively. However, climate change can force these Lake
Nasser to be drier. The average annual inflow reductions at High
Aswan Dam due to climate change are estimated to be 24%, 35% and
36% for near future (2011-2040), intermediate future (2041-2070)
and far future (2071 -2100), respectively.

Abstract:
Complementary
and alternative use of traditional herbs has raised hopes for
finding curative options for liver diseases. In the present
study, the curative effect of licorice extract against diethyl
nitrosamine (DENA) and carbon tetrachloride (CCl4)-induced
hepatocellular carcinoma (HCC) in male rats in the presence or
absence of the antineoplastic agent cisplatin was investigated.
The results showed that treatment with DENA/CCl4
caused oxidative stress as indicated by obtained increase in
malondialdehyde (MDA) and hydrogen peroxide (H2O2)
in the liver. Meanwhile, reduction in the antioxidants including
glutathione
(GSH), superoxide dismutase (SOD) and glutathione-s-transferase
(GST)] was observed. Also, the results showed induction of
apoptosis as reflected by increase both p53 and caspases-3 along
with decreased Bcl-2 in the liver. This was accompanied with
changes in the hepatic function biomarkers which characterized
by increased levels of alanine aminotransferase (ALT), aspartate
aminotransferase (AST), alkaline phosphatase (ALP) and total
bilirubin; and decrease in total proteins and albumin content in
the serum. Treatment of DENA/CCl4 rats with cisplatin
significantly reduced the changes in most parameters of
oxidative stress, apoptosis and liver function, when compared to
the untreated group of DENA/CCl4.Administration of licorice
significantly alleviated the adverse effects induced by
DENA/CCl4 in the presence or absence of cisplatin in all
investigated parameters, compared to the untreated HCC group. In
intact rats, administration of licorice alone had no side
effects on mentioned parameters, while cisplatin caused adverse
changes. Treatment with licorice in rats treated with cisplatin
ameliorated induced hepatotoxicity by cisplatin. In conclusion,
obtained results showed that treatment with licorice alone
seemed to be more effective in attenuation of the
hepatocarcinogenic action of DENA/CCl4 than treatment
of licorice pluscisplatin or cisplatin alone. Since licorice,
unlike cisplatin, has no side effects,
further studies on experimental animals are required in order to
assess the strategy of cancer treatment using licorice extract
and its active ingredients.

Abstract:
Introduction:
We aimed to study
the management of a cohort of elderly patients (≥ 65 years old)
with metastatic colorectal cancer (mCRC) treated by our oncology
team between April 2010 until December 2012 in relation to their
comorbidities and functional abilities. Patients and methods:
That was an observational prospective study of 43 patients
with mCRC. Results: Thirteen patients were treated with
XELOX (oxaliplatin and capecitabine) regimen. They had
Cumulative Illness Rating Scale for Geriatric (CIRS-G) score of
0-3, Lawton Instrumental Activity of Daily Living (IADL) score
of 8 and performance status (PS) of 1. Partial response (PR) of
61.5% and stable (SD) 30.8% were achieved.
The median progression free survival (PFS) and overall
survival (OS) durations were 10 and 16 months respectively. Ten
patients had oral capecitabine. They had CIRS-G score of 0-3,
IADL score of 4-8 and PS 2. Two had PR (20%) and 6 SD (60%). The
median PFS and OS were 11 and 12 months respectively.
Five patients were treated with FOLFIRI (Irinotecan and modified
Degramont) regimen. They had CIRS-G 1-3, Lawton IADL of 5-8 and
PS 1-2. Two patients had PR (40%) and 1 (20%) SD. Median PFS and
OS were 9 months and 14 months respectively. Fifteen patients
had ischaemic heart diseases were treated with Raltitrexed. They
had CIRS-G score of 2-3, IADL score of 4-8 and PS 1-2. PR and SD
rates were 35.7% each. Median PFS and OS were 7 and 10 months
respectively. Conclusion: CIRS-G score, IADL and PS are
quite helpful tools in assessing elderly patients prior to
chemotherapy.

Abstract:
In this work, we take into account the semiconductor quantum dot
(QD) rate equations based on a microscopic approach which used
with a fitting expressions of nonlinear Coulomb scattering
rates. The scattering rates play a role in the rate equations of
semiconductor QD laser. This paper discussed the influence of
different values of the QD density upon the nonlinear Coulomb
scattering rates in transition stage and at the steady state of
QD laser output. Our results show the dependence of the
carrier-carrier scattering rates on both the wetting layer and
QD.

Abstract:
A series of new tetrazole
heterocyclic derivatives were designed and synthesized through
reaction of 5-chloro-1-phenyl-1H-tetrazole with
4-hydroxybenzoic acid hydrazide to give the key intermediate
4-((1-phenyl-1H-tetrazole-5-yl)oxy)benzohydrazide, which
was condensed with different aromatic and heterocyclic aldehydes
to give a series of tetrazole N-aroylhydrazone
derivatives 6-19 followed by reflux with thioglycolic
acid or acetic anhydride to give the targeted tetrazole
4-thiazolidinones 20-29 and 2,5-oxadiazoline derivatives
30-40. Selected compounds was tested for their in
vitro antimicrobial and anticancer activity. Compounds with
the most pronounced antimicrobial activity 3, 14, 26, and
35, in addition to 36 were tested for their in
vitro cytotoxic activity against (HuH-7) and (CaCo-2) cell
lines. Compound 14
and 35 were the most active against
(CaCo-2) cell line with IC50
of 4.2μM and 9.8μM, respectively, while compound 35 was
the most active against (HuH-7) cell line with IC50
of 24μM. On the other hand, incorporation of 1-phenyl-tetrazole
moiety into propyl paraben 2 led to three times increase
in the antifungal activity. A molecular modeling study was
performed on propyl paraben 2 and its tetrazole
derivative 3.

Abstract:
Objective:
To compare
between the effect of Prophylactic Modified B-Lynch suture,
Carbetocin and Oxytocin on prevention of atonic postpartum
hemorrhage following cesarean section in pregnant women at high
risk of atonic postpartum hemorrhage.
Study design:
Randomized controlled prospective study on 150 pregnant women at
high risk to develop postpartum hemorrhage were going to have
Cesarean section. They were randomized to have during cesarean
section either Prophylactic Modified B-Lynch suture or receive
Prophylactic 100 microgram of Carbetocin IV or Prophylactic 20
units of oxytocin IV infusion on 1000 ml saline with a rate of
250 ml per hour. The primary outcomes were to estimate mean
operative blood loss, compare the occurrence of major obstetric
hemorrhage (Blood loss ≥ 1000 ml),
objective changes in hemoglobin preoperatively and
postoperatively, and need for additional uterotonic agents or
additional interventions to control bleeding. Secondary outcomes
included occurrence of severe anemia, need for blood
transfusion, side effects (e.g. paralytic ilieus) and postnatal
hospital stay. Results: In our
study the Estimated mean operative blood loss between the three
groups was about 100ml less in Modified B-Lynch group than in
Carbetocin and Oxytocin groups
(P- value < 0.05), Average decrease in haemoglobin 24 hours after delivery in
Modified B-Lynch was 1.1 ± 0.5
gm/dl compared to 1.7 ± 0.56 gm/dl in Carbetocin group and 1.8 ±
0.58 gm/dl in Oxytocin group
(P- value < 0.05),
None of the patients who had Modified B-Lynch developed major
obstetric haemorrhage compared to 2 patients in Carbetocin group
& 3 patients in Oxytocin group, only 1
patient in
Modified B-Lynch required
additional uterotonic agent
to control bleeding
compared to 2 patients in Carbetocin group and 4 patients in
oxytocin group.
Conclusion:
Modified B-Lynch suture appears to be more effective in
maintaining adequate uterine tone and preventing excessive blood
loss in patients undergoing cesarean section with high risk to
develop postpartum hemorrhage.

Abstract:
Introduction:
Colorectal cancer stem cells (CRCSCs) are cells that have the
ability of self-renewal, tumour propagation and resistance to
systemic anticancer treatment. They are identified by expression
of CD44 and CD133 antigens. We aimed to study the expression and
prognostic significance of CRCSCs in a cohort of colon cancer
patients.
Material and method:
A total of 84 consecutive patients with newly diagnosed stage
I-III colon cancer were included in this study between 2005-2010
in the Oncology Center of Mansoura University (OCMU). The resect
tissue samples were prepared and stained by Haematoxylin and
Eosin as well as immune-histopathological staining for CD133 and
CD44. The clinic-pathological features and outcome of those
patients were correlated with CD133 and CD44 expression.
Results:
Among the 84 patients; 12 were in stage I (14.3%); 38 in stage
II (45.2%) and 34 in stage III clinical stages CRC (40.5%).
The median age was 52 years. All patients underwent
curative resection surgeries. High grade adenocarcinoma was the
most common histology.
The median disease free survival (DFS) is 41 months among the
studied patients. In multivariate analysis, the relations of DFS
to higher grade, advanced stage and CD133 score were
statistically significant. Thirty three cases (39.3%) died at
the end of follow up. The median overall survival was not
reached.
Conclusion:
CD133 score, stage and histological grade are independent
prognostic factors of disease free survival in colorectal
cancer.

Abstract:
The terminal end of
the spinal cord and filum terminale had significant roles in
spinal cord pathophysiology, therefore, the present study was
designed to investigate the structural characteristics for that
areas.
Ten white adult male and female New Zealand rabbits were used in
this experiment. Transcardial perfusion technique was made and
the spinal cord terminal ends and fila terminale were collected
and processed for histological examination by light and electron
microscopes. The results revealed that the spinal cord
transformed into conus medullaris at the end of the second
sacral segment at which a characteristic lateral and ventral
neuronal interdigitations between the white and gray matter was
evident. The filum terminale internum had a different zonal
organization to the white and gray matters. The filum terminale
externum formed from fibrous stroma and characterized by an
absence of neurons, glia and ependyma.

Abstract:
Coxiella burnetii, the bacterium causing Q fever, is an
obligate intracellular biosafety level 3 agent. In animals, the
organism is mainly found in the reproductive system and may
primarily cause abortion or infertility. Antibodies to this
organism have been reported in a wide range of animals including
mammals, reptiles, amphibians, and birds. In the present study,
a total of 125 serum, bulk tank milk, vaginal swab, placenta and
internal organ of aborted foeti samples were collected from
aborted she camels and apparently healthy in Marsa Matrouh
governorate, Egypt to detect the prevalence of C. burnetii
at flock level by ELISA and Real-Time PCR as well as the
pathogen amplification in Embryonated Chicken Egg (ECE).This
study proves that camels in Egypt may play an important role as
a reservoir of C. burnetii and they could be a
significant source for the transmission of Q-Fever to other
animal species and to humans. The preferred route of shedding of
C. burnetii in camel appeared to be the milk followed by
placenta.

Abstract:
Long non-coding RNAs (lncRNAs)
are a new class of non-coding RNA molecules in metazoan genome
and might play widespread roles in gene regulation and other
cellular processes. This review will highlight our current
understanding of lncRNA biology, mechanisms of action, and
summarize recent work on the role of lncRNAs including lncRNA
ANCR in bone remodeling. These studies epitomize emerging
importance of lncRNAs in the regulation of osteoblast
differentiation and function, indicating new potential targets
for bone wound healing.

amr_73@yahoo.com
Abstract;
This study was carried out at Serapium forest at Ismailia
governorate and Luxor forest at Luxor governorate. The
experiment was conducted to assess the influence of different
amounts of water with different Solar Radiation Energy (SRE) on
some growth parameters [Height and root collar diameter (RCD)]
for two forest tree species (Azadirachta indicaand
Gmelina arborea).
Thus; experiment was
laid out on complete randomized block design with two factors.
First factor is amount of water which comprise into five
treatments (Q1, Q2 Q3, Q4
and Q5) with average (130%; 1.15%; 100%; 85%;
70%) respectively from total water applied. Second factor is two
Solar radiation energy (SRE) with [6902.8 MJ/m2/year
at Ismailia and 7717.1 MJ/m2/year at Luxor] during
period November 2013 to March 2015.
The results revealed that the water quantities has a significant
influence on total tree Height for A.indica especially
between Q2 and Q5; however; amounts of
water have not any significant influence on both tree height and
(RCD) for G.arborea. Moreover; at Luxor the SRE recorded
a best value for A.indica tree height comparing with SRE
at Ismailia by 2.1mm/MJ.m-2. On the other hand;
G.arborea obtained a highest value for tree height parameter
at Ismailia (SRE) by
1.38mm//MJ.m-2.
Finally;
effective water use for A.indica tree height at Luxor is
(51.3cm/m3) and at Ismailia is (40.7cm/m3)
but with G.arborea the effective water use is (30.48cm/m3)
at Ismailia and (23.7cm/m3) at Luxor.

Abstract:
Sensible and insensible
perspiration are crucial aspects of clothing comfort for knitted
garments; examined as wettability and WVTR, respectively.
Sensible perspiration is when moisture or insensible
perspiration is accumulated and transformed into water droplets
so called sweat. To maximize comfort, sweat produced during
various activities should be able to evaporate through a
clothing system. The purpose of this research is to study the
effect of non-thermal atmospheric pressure plasma produced in O2
and air, onto comfort properties of warp knitted PET. Through
experimental, wettability and WVTR (Water Vapor Transfer Rate)
were examined, as well the durability factor was studied using
bursting strength test. Surface morphology of tested fabrics has
been detected using SEM (Scanning Electronic Microscopy),
finally, FTIS (Fourier transforms infrared spectroscopy)
analysis has been obtained searching for development of any new
chemical groups. Resultant data, showed wettability values to be
accelerated, a negligible effect of ±3% WVTR was obtained, in
general, this would enhance wearer comfort properties of knitted
garments. It is recommended to utilize lower discharge power, of
O2 Plasma, obtaining the optimum perspiration
transfer with minimum loss in fabric strength.
Even though, wettability has been enhanced for textile printing
purposes, using Plasma in previous studies, none has been used
for WVTR and comfort properties.

Abstract:
The present investigation was
conducted during the two successive seasons of 2012 and 2013 on
"Anna" apple budded on Mauls rootstock in a private orchard,
Tanboal road from Cairo–Alexandria desert road at El-Monofeya
governorate. The trees were 10-years old and planted at 3x3m
apart. CPPU (Sitofex at (100 cm3/20L water), Inca at
(40cm3/ 20L water) and Calbor at (40 cm3/20L
water) were sprayed three times (at full bloom, fruit set, and
month before harvest), and treatment of Kemazed 50% WP at (50
g/100 L water) was sprayed twice, 30 and 15 days before harvest.
in addition, Humic acid at (60 cm3/tree) as a soil
drench was applied in the same pervious times to assess their
effect on yield, fruit quality, storability and disease
severity. The results showed that, Sitofex effectively increased
fruit Iet percentage and number of fruits/ branch. Calbor
treatment increased fruit yield, number of fruits / branch and/
tree as well as fruit firmness and decreased fruit drop
percentage. Hence, CPPU+ Calbor treatment induced much more
fruit yield, number of fruits / tree and fruit firmness. Humic
acid could increase fruit quality (fruit weight, size and
diameter). Inca treatment decreased fruit juice acidity and
fruit shape index. CPPU, Inca and Inca+ CPPU effectively reduced
fruit weight loss and maintained fruit firmness during storage
at 3°C and 90 R.H. for 12 weeks. Calbor treatment improved all
studied fruit quality attributes. The highest disease severity
was obtained by two pathogens Penicillium puberulum
and Scytalidium dimidiatum. Kemazed 50% WP
fungicide completely inhibited the growth of both Penicillium
puberulum and Scytalidium dimidiatum in
vitro. Chitosan decreased the mycelium growth of both them
where the inhibitor effect increased with increasing chitosan
concentration up to 1.0%. The highest disease severity with
P. puberulum and S. dimidiatum occurred when fruit
treatment with Acetic acid at 0.5% and Control without chitosan,
while Chitosan + Kemazed 50% WP and Chitosan +calboro induced
the least disease severity.

Abstract: Background:
Several studies indicated that monosodium glutamate (MSG)
disrupts the metabolism, the development, and the functions of
various organs, such as liver, thymus, ovaries, kidney, and many
parts of brain, including cerebellum. Nitric Oxide (NO) is known
to be responsible for the organization of many biological events
in the mammalian body as a second messenger and a neural
messenger. Some studies found that NO is a neuroprotective
substance while others qualify it as a neurotoxic. Aim: This
study was designed to investigate the effect of non-selective
inhibition of nitric oxide synthase enzyme isoforms on
cerebellar structure and function in normal
rats and in rats with MSG-induced cerebellar toxicity.
Material and methods:
The study groups included thirty two male adult albino
Sprague-Dawley rats which were divided into four groups; group I
(control), group II (LNAME-treated), group III (MSG- treated)
and group IV (combined LNAME and MSG-treated). Motor
coordination was assessed by rotarod test. Cerebellar nitrite
concentration was measured. Histopathological evaluation of
cerebellar structure and immunohistochemical examination for
caspase-3 were done.
Results:
Both LNAME and MSG significantly impaired cerebellar function
and resulted in marked cerebellar injury and an increase in
apoptosis. This effect was most prominent in group III.
Conclusion:
Inhibition of nitric oxide synthase enzyme disturbed cerebellar
structure and function in normal rats and potentiated
MSG-induced cerebellar toxicity. Further studies are required
for better understanding of the role of the NO pathway and
developing therapeutic strategies that are based on manipulation
of NO synthesis.

Abstract:
Background:
Although tension free repair of inguinal hernia with a mesh is
the standard technique in many countries with high standard of
living, its use remains low in countries with low standard of
living due to the initial high cost of the polypropylene mesh.
The tissue-dependent techniques (herniorrhaphy) are still
acknowledged to be acceptable for the repair of primary inguinal
hernia (European Hernia Society guidelines). Shouldice and
Modified Bassini repairs are well known tissue repairs of
inguinal hernia in Egypt. Desarda’s technique, is an original
hernia repair technique which use undetached segment of external
oblique aponeurosis to strength the posterior wall of the
inguinal canal. Desarda’s repair of inguinal hernia is not
well-known in Egypt. This study will record and evaluate the
short-term outcome of inguinal hernia repair with Desarda’s
technique. Patients and Methods: One hundred and eighty
patients presented with unilateral, uncomplicated, primary
inguinal hernia (direct, indirect, and/or bantallon) were
recruited through the surgical department. Postoperative pain
was evaluated using a visual analogue scale 3 hours after the
operation, on the 3rd and 7th post-operative days. The primary
outcomes measured were postoperative early recurrence, and wound
complications. Foreign body feeling, and return to daily
activities were examined in hospital and at 7 days, 1, 6, and
12months post-operatively. Results: Of the 180male
patients underwent surgery, three patients were lost in the
follow up period and one patient died. During the follow-up of
the remaining 176 patients, only two recurrences recorded after
one year post-operatively (1.1%). Chronic pain was recorded in5
cases (2.8%). Most patients (92%) returned to normal activity on
the third week. There was small number of the patients with
wound complications. Conclusion: Results of primary
inguinal hernia repair with Desarda’s techniqueis compatible
after the end of one-year of follow-up to other recorded early
postoperative complications of Lichtenstein hernioplasty, and
modified Bassini and Shouldice herniorrhaphy. The technique may
adda new technique of pure tissue-based repair available for
treating inguinal hernias.
