Background: The objective
of this study is to analyze the incidence of congenital urogenital malformations
in human fetuses with neural tube defects (NTDs). Methods: We studied 320 human
fetuses (214 males and 106 female) ranged in age from 12 to 35 weeks
post-conception (WPC). The fetuses were carefully dissected with the aid of a
stereoscopic lens with 16/25× magnification. The
abdomen and pelvis were opened to identify and expose the urogenital organs. We
studied the incidence of renal, urete...

The study investigated the effect of training and
motivation on job performance of library personnel of University of Lagos,
Lagos State, Nigeria. Observation show that library users frequently complain
that library staff do not attend to their queries properly. This phenomenon could
be attributed to lack of training and motivation to the library personnel.
Survey method was used in the study. The population comprised 135 library
personnel in the University of Lagos. Total enumeration was employ...

Stomach is considered the “gold standard” as an esophageal substitute
after esophagectomy. Reflux disease is considered an unavoidable consequence of
esophageal resection followed gastric interposition. Reflux esophagitis shows a
progression from inflammation to erosions and to the development of columnar
lined metaplasia. With the use of a gastric interposition, the most popular
option to reconstruct the esophagus resected for malignant or benign conditions
creates an in vivo model of re...

The epithelial-to-mesenchymal transition (EMT) is a process where epithelial cells
with polarity and tight junction change into mesenchymal cells without polarity
and intercellular adhesion to obtain an ability of invasion and metastasis. Interest in the EMT theory has grown exponentially in the last several
years and it has become one of the hottest subjects in cancer research.
However, there is no convincing evidence of EMT in human tumor and numerous
paradoxes do exist about EMT theory from m...

Ecological
followed previous reintroductions of 262 juvenile Astrochelys radiata in the sacred forest Sirempo have revealed that
individuals released directly without acclimatization left the site at 98%. The
local habitat fulfilled all the conditions necessary for the development and
survival of the species, and this site was
recognized as distribution range of the species, but with a population whose
abundance to decline over the last ten years. The research project “Development of Tech...

Water absorption properties of recycled materials
play an important role in pavement performance. The performance of aggregates
changes after absorbing water, then it affects highways layers such as base,
subbase, capping. This is why these materials must comply requirements of codes
and standards. With regard to the increasing trend of application of recycled
aggregates in highways layers, this issue needs more investigation. This
research is only a part of our large research
programme on three...

In this article, we concerned with the development of a method for solving two point boundary value problems of ordinary differential equations. To develop method ,we consider derivative of solution of a problem as a intermediate problem (IP).The analytical solution of the problem and IP were locally approximated by a nonlinear function with xed step lenght.Some numerical experiments have been carried out to show the performance and effectiveness of the propose...

In this article, we report the finite
difference method for numerically solving the Goursat Problem, using uniform
Cartesian grids on the square region. We have considered both linear and
nonlinear Goursat problems of partial differential equations for the numerical
solution, to ensure the accuracy of the developed method .The results obtained
for these numerical examplesvalidate the eciency, expected order and accuracy
of the method.

The aim of this study was to investigate the
effects of the cognitive-behavioral oriented awareness program on depression
levels of obese individuals. Both the experimental and control group included
20 individuals. A pre and post-test research model was used in this study. Beck
Depression Inventory (BDI) was the scale applied to both of the study groups.
Mann-Whitney U test and Wilcoxon signed-rank test were used to find out if
meaningful differences em ...

Bambui and Bambili residents collect water from different sources to
fulfill their daily needs. Varieties of microbes exist in water including
bacteria, algae, fungi, protozoa and viruses, where
they form a complex ecosystem whose dynamics are usually difficult to
comprehend. Those varieties of microbes play an important role for
contamination of water and results in various outbreaks of diseases and death.
The aim of this study is to evaluate the bacter ...
