Abstract:
The study was
carried out to assess the cationic and anionic concentration in
boiler water. The adverse impact of these ions on the surface of
the boiler was also observed. The water samples were colleted
from five industrial units and were compared with each other and
with their corresponding outlets. The amounts of iron (Fe+2),
aluminum (Al+3),
sodium (Na+2),
potassium (K+1),
nitrate (NO3-3),
silica (SiO2)
and sulphate (SO4-2)
were calculated in ppm and noted that the ionic
concentration gradually increased in the boiler outlet sample
except that of silica which decreased in the outlet water.
Presences of such ions in the boiler feed water cycle up and
concentrate in the boiler. As a result, deposition takes place
on internal surfaces of the boiler, particularly in the high
heat transfer areas, which act as insulators and can cause
overheating and failure. The outlet water containing high
amounts of the concentrate, if discharged into the rivers or
lakes or any agriculture area near the industrial unit, can
effect human and plant life in a serious way.

Abstract:
The main aim of
this study is to evaluate the role of Cladophora sp
or Spirulina platensis (as biofilters) for the
reduction of microbial load in Nile water as well as reduce the
organic matter content (which produce carcinogenic compound when
exposed to the chlorine) before chlorine treatment in Water
Treatment Plants for potable water. The results showed that
Cladophora sp succeeded in removing tested microbial
spp., with, a ratio of 12.7, 21.1, 33.3, 11.1, 32.1, 27.2, 27.6
30.8 34.4 and 33.3% for
total viable
bacterial count at (37 oC,and
22 oC)
total coliform, fecal coliform, fecal streptococci, salmonellae
group, Pseudomonas spp., total staphylococci, yeasts and
fungi, respectively. On the other hand, the total organic
carbons (TOC) were 9 before filtration, while after filtration
was 7.5 ppm, but Spirulina platensis reduced TOC from 9
to 6.25 ppm. In addition, the tested microorganisms in Nile
water passed through biofilters were absent by treatment with
2ppm chlorine dose for 30 min. While in case of unfiltered Nile
water samples some microbial groups were present even with
chlorine dose 6 ppm. Spirulina platensis was more
efficiency where the results show that the ratio removals were
42.3, 51.5, 77.1, 80.6, 75, 45.5, 62.1, 92.3, 56.3 and 50% for
total viable
bacterial count at 37oC,
22oC,
total coliform, fecal coliform, fecal streptococci, salmonellae
group, Pseudomonas spp., total staphylococci, yeasts and
fungus, respectively. After filtrated the Nile water through
Spirulina platensis and treated with chlorine (dose 2ppm)
for 10 minutes, the tested microbial groups were absent. In the
unfiltrated water sample for some microbial spp. were present
for 60 minutes after treatment with chlorine dose 6 ppm. These
results confirmed the reduction of the already applied chlorine
concentration and decrease the presence of carcinogenic compound
in drinking water to improve water quality.

Abstract:
Prostate
cancer is the most common malignancy among men. Hormonal factors
play an important role in growth of prostate tissue and
induction of prostate carcinogenesis. The use of sequential
hormonal therapies is a common practice in the systemic therapy
of advanced prostate cancer. The aim of this study is to clarify
the possibility of use the measuring serum level of androgens
(testosterone (T) and adrenal androgens
dehydroepiandrostenedione sulphate (DHEA-s)
and androstenedione (AD)), gonadotropins (Follicle-stimulating
hormone (FSH) and luteinizing hormone (LH)) to improve the
accuracy of diagnostic serum prostate specific antigen (PSA),
and to examine the effect of these parameters in the progression
of prostate cancer from androgen dependent to androgen
independent after orchiectomy. Results
indicated that serum DHEA-s level
showed insignificant decrease in hyperplasia group as compared
to androgen independent group (P = 0.185) and a significant
decrease in hyperplasia group as compared to androgen dependent
group (P = 0.001) while, no significant variation was found
between androgen dependent and androgen independent groups (P =
0.341). Combination of PSA and DHEA-s increase the sensitivity
of PSA to differentiate between benign hyperplasia and cancer
from 93.5% to 96.8%. Serum FSH showed no statistically
significant variation between androgen dependent group and
hyperplasia group (P = 0.109), while, there was a highly
significant increase in androgen independent group as compared
to androgen dependent (P = 0.002) and hyperplasia groups (P =
0.001). Serum LH showed statistically significant increase in
androgen dependent group (P = 0.001) and androgen independent
group (P = 0.001) as compared to hyperplasia group, also, there
were a statistically significant variation was found between
androgen dependent and androgen independent groups (P =
0.002). Serum T showed statistically significant decrease
between androgen dependent group and hyperplasia group (P =
0.021). Also, there was a highly significant decrease in
androgen independent group as compared to androgen dependent and
hyperplasia groups (P = 0.001). It can
be concluded that
measuring of DHEA-s together with PSA can be used
to increase the differentiation between prostate cancer and BPH
and controlling of adrenal androgens and gonadotropin hormones (FSH
& LH) would be efficient in delaying the transformation of
prostate cancer from androgen dependent to
androgen-independent.

ABSTRACT:
The hepatoprotective effect of pomegranate and guava against
carbon tetrachloride-induced hepatotoxic in rats liver was
evaluated. The hepatoprotective period, rats treated with
pomegranate peel and guava leaves ethanolic extracts or
silymarin for 21 consecutive days could significantly decrease
in the liver weight when compared with CCl4-treated
group. In the curative period, rats treated with pomegranate
peel and guava leaves ethanolic extracts or silymarin completely
restored the increase of liver weight and no significant
difference when compared with normal group. In the
hepatoprotective period, rats treated with pomegranate peel
ethanolic extracts or silymarin during CCl4
administration significantly increased in the serum total
protein content and albumin when compared with CCl4-treated
group. No significant effects were observed on the serum
globulin contents compared with normal control. In the curative
groups, the highest increase in serum total protein content and
globulin were noticed in the rats treated with pomegranate peel
ethanolic extracts. In the hepatoprotective and curative
periods, rats treated with pomegranate peel and guava leaves
ethanolic extracts or silymarin significantly decreased in the
activities of ALT, AST, GGT, lysosomal enzymes (ACP, β-GAL and
β-NAG) and lipid peroxidation when compared with CCl4-treated
group. Significantly increases were found in the activities of
SOD and CAT enzymes when compared with CCl4-treated
group. The content of reduced glutathione and GST in all
treatments generally decreased as compared with normal group
except treatment rats with guava leaves ethanolic extracts. In
the hepatoprotective and curative period, the highest damages in
liver tissue were found in the order carbon tetrachloride >
guava leaf ethanolic extract > silymarin > pomegranate peel
ethanolic extract > normal control. This clearly explained the
reason for the antioxidant activity of guava leaves, pomegranate
peel and silymarin.

Abstract:
This work was
carried out in the course of a screening program for specific
actinomycetes bioactive substances that demonstrated inhibitory
effects against some pathogenic strains. Twenty-eight
actinomycete strains were isolated from soil sample collected
from
Farm
Jabbar
districted,
Al-Khurmah governorate, KSA.
One of the
actinomycete culture, symbol 143 from two cultures was found to
produce a wide spectrum antifungal agent (unicellular and
filamentous fungi).
The nucleotide
sequence of the 16s RNA gene (1.5 Kb) of the most potent strain
evidenced an 77% similarity with
Streptomyces
albidoflavus.
From the taxonomic features, the actinomycetes isolate 143
matched with Streptomyces
albidoflavus
in the morphological, physiological and biochemical characters.
Thus, it was given the suggested name Streptomyces
albidoflavus,
143.
The
parameters controlling the biosynthetic process of antifungal
agent formation including: inoculum size, different pH values,
different temperatures, different incubation period, and
different carbon and nitrogen sources were fully investigates.

Abstract:
The environment
in which mines are placed is extremely variable in terms of
climate, vegetation, soil type, depth of ground water table, and
topography. Variations in environmental conditions influence
sensor performance because in general, landmine sensors exploit
soil and environmental conditions to discern between mines and
other objects. Little effort has been made on evaluating the
environmental conditions that affect sensor performance. In this
work, the effect of relative humidity on thermal signature of
buried objects was examined. It was observed that relative
humidity has inverse relationship to the heat emitted by the
different objects. Also, it may be difficult to use this method
(thermography) to detect buried objects in areas of high
relative humidity as region of high relative humidity is usually
characterized by little sunshine. Material
identification/characterization could only possible when the
relative humidity is low as this was the only period when the
different buried objects had appreciable differences in thermal
signature.

Abstract:
Food
preservation and storage methods in sub-Saharan Africa are
poorly conceived, carried out and inadequate. This has resulted
in enormous food losses in storage as a result of deterioration
by microorganisms, rot and rodents. Africa is blessed with
various types of food produce and also possesses
diverse indigenous
knowledge systems for their preservation and storage. These have
been used by most cultures over time to preserve their produce
after harvest.
Advanced food
preservation techniques which include methods such as canning,
pickling, drying and freeze-drying; irradiation, pasteurization,
smoking, and the addition of chemical additives or spices etc.
are used globally but these methods are usually not affordable
or practicable for the resource-poor natives. Traditionally,
Long-term
methods like fermentation and drying have been used for fruits
and vegetables, while short term methods used include storing in
buckets and in clay pots; and also blanching. For grains,
storage in cribs and silos is practiced. Traditional ways of
storing yam include keeping them fresh in barns, on platforms or
in the ground. However for cassava, being a highly perishable
crop, methods like re-burying in trenches; applying a thick coat
of soft clay or mud; or keeping small quantities in water have
been used for short-term storage. Improved methods of
preservation and storage available for cassava include the field
clamp method; storage in boxes or in plastic film bags with
various lining materials.
Generally, the
non-adoption of new methods by the people slows down
improvements that have been made through research.
Collaborations incorporating the plus aspects of the present
methods with research into new ways of food preservation and
storage are advocated in other to save more food for the future.

Abstract:
The physical
properties of doum palm fruit were determined as a function of
moisture content. The average dimension of doum palm fruit in
the three principal axes (viz., length, width, and
thickness) and its equivalent diameter, projected area,
sphericity, porosity, bulk and true densities were determined
for moisture contents ranging from 24.05 to 67.59% d.b and were
found to be 60.65, 48.78, 47.09 and 51.61 mm, 19.94 cm2
and 0.85 respectively while the true and bulk densities
increased from 711.05 to 958.53 kg/m3 and 370.51 to
483.77 kg/m3 respectively with moisture content but
the porosity increased from 46.45 to 51.66% and later decreased
to 49.53%. The dimension of doum palm fruit with its equivalent
diameter, projected area and sphericity were found to be
constant with moisture content variation. It was found that the
relationships between true and bulk densities and moisture
content of doum palm fruit followed a linear pattern while that
of porosity exhibited a non-linear relationship with the
moisture content at 0.05 significant level.

Abstract:
The development of cachexia is a particular predictor of adverse
prognosis in chronic heart failure (CHF). Less is known about
anabolic metabolism in CHF. Leptin – the hormone product of
obesity gene- has been shown to inhibit food intake, increase
energy expenditure and fat oxidation. Insulin sensitivity and
secretion is related to leptin. Leptin has been reported also to
stimulate proliferation of CD4 T cells and increases cytokine
production. The study aimed to investigate leptin, insulin
sensitivity and tumor necrosis factor-α (TNF-α) in chronic heart
failure with and without cachexia. We studied 51 male patients
and 23 male healthy control subjects, of matched age. Of the CHF
Patients, 24 were cachectic (cCHF) with non-edematous weight
loss >7.5% over at least 6 months and 27 non cachectic. Serum
insulin, leptin and TNF-α were measured using commercially
available ELISA kit. Insulin sensitivity was assessed by
intravenous glucose tolerance test. Compared with the healthy
control subjects, patients had elevated levels of leptin,
fasting insulin and TNF-α (P<0.001), but reduced insulin
sensitivity (p<0.001).The cCHF subgroup compared with ncCHF
subgroup showed reduced leptin and fasting insulin levels
(P<0.001 & P<0.01 respectively) and elevated TNF-α levels
(P<0.001). In both patients and control subjects there was a
positive correlation between leptin and fasting insulin levels
(r=0.59, P<0.001 & r=0.54, P<0.05 respectively). The relative
risk of incidence of cCHF in NYHA functional class (Ι &П) versus
NYHA functional class (ІІІ &ІV) was 0.427 (P<0.05). In
conclusion CHF is hyperleptinaemic state and is associated with
decreased insulin sensitivity and elevated serum insulin levels.
The state of cardiac cachexia is associated with higher TNF-α
levels and more worse NYHA functional class. Leptin and TNF-α
may be a valid targets for novel therapeutic interventions in
patients with CHF.

Abstract:
A worldwide concern in the use of synthetic antioxidants in food
safety necessitates investigation into natural sources of
antioxidants. An invitro assay of antioxidant properties of
alpha-tocopheryl acetate, thyme leaf extract, Ethiopian pepper
extract and wheat germ vitamin E was carried out using eight 14
weeks old broiler chicken. The muscle tissue of each chicken
were separated, chopped, mixed thoroughly and divided into
treatment group of 800g each. Experimental samples were prepared
by blending 0.8% w/w addition of thyme leaf extract, Ethiopian
pepper extract, wheat germ vitamin E and alpha-tocopheryl
acetate while the control did not contain any. Each treatment
sample was further divided into 8 sub-samples (80g each). Four
samples per each treatment were separately packed in aluminum
foil paper and refrigerated for 12 days at 4oC for
raw meat Thiobarbituric Acid Reactive Substances (TBARS)
analysis at interval of 3, 6, 9, and 12 days. Four sample per
each treatment were steam cooked for 12 minutes, separately
packed in aluminum foil paper and refrigerated for 6 days for
cooked meat TBARS analysis at interval of 2, 4 and 6 days. The
result indicated that post mortem addition of natural and
synthetic sources of antioxidant had no significant effect
(P>0.05) on cooking yield and cooking loss of broiler meat
during storage. Comparatively, the tested natural antioxidant
sources reduced the formation of peroxide more effectively
(P<0.05) than alpha-tocopheryl acatete in refrigerated raw and
cooked broiler chicken meat and could be used to replace
synthetic compounds which poses health hazard to the consumers.
However more studies are required to remove the
chlorophyllization effect of thyme leaf extract and Ethiopian
pepper extract on the meat.

ABSTRACT:
This study was
designed to assess the selected trace element levels among
apparently healthy geriatrics (test) in Ekpoma and compare it
with levels among healthy young adults (control). Blood samples
were collected from the study population using standard
techniques. The serum trace element levels were then determined
using atomic absorption spectrophotometer. Our result showed
that there was a significant increase in selenium and chromium
levels in geriatrics when compared with control (P < 0.05).
there was a non significant decrease in serum Manganese and Zinc
levels in geriatrics when compared with control. The serum
copper and magnesium levels were higher in geriatrics when
compared with control, however, this was not statistically
significant (P > 0.05). It can therefore be concluded that
apparently healthy geriatrics in Ekpoma have adequate essential
trace element intake when compared to the younger population.
