Background: Men with azoospermia require testicular and epididymal sperm aspiration for intracytoplasmic sperm injection. Women over 37 years of age demonstrate
an increase number of immature oocytes after induction of ovulation. The development of a technique for in vitro maturation (IVM) and fertilization (IVF) of
the oocytes using testicular, epididymal and vassal sperm (TS, ES, VS, respectively) will be of therapeutic value for the treatment of azoospermic patients.
Objectives: The goal of the study was to develop an animal model for the treatment of infertile couples with obstructive azoospermia and immature oocytes.
Materials and Methods: Canine ovaries and testes were collected from a local animal clinic. Immature oocytes were retrieved from the ovaries and cultured in modified tissue
culture medium (MTCM). The mature oocytes were in vitro fertilized by TS, ES, and VS. The normality of the fertilized oocytes was studied.
Results: Sperm motility index was significantly higher (P<0.01) in sperm retrieved from the vas deference compared to ES and TS. The concentration of the sperm was
significantly higher (P<0.05) in the testes compared to epididymis and vas deference while VS and ES normal morphology were significantly (p<0.01) better than TS. Viable oocyte
percentage was significantly higher (P<O.05) in 72 hours versus 96 hours culture durations. Significant higher IVF was reported in VS compared to other groups (P < 0.05) and the SPI
was significantly higher after 96 versus 72 hours duration (P<O.05).
Conclusion: IVM of the oocytes in MTCM for 72 and 96 h resulted in a significant increase in IVM rate compared to 48,120, and 144 h durations. In vitro viable mature
oocytes showed higher IVF rates when fertilized with VS compared to ES and TS. The results showed that canine oocytes are good model for azoospermic patients.
capable of the measuring with a high degree of precision in a single instrument. Total stations device are used for station setting up, setting-outmany points from one station. Their major purpose of this work is to take advantage of total station for setting up building and to establish 3D representation using AutoCAD program. The area of the study was Civil Engineering Department at Baghdad University campus AL Jadiriyah. The completion of the work is done in two stages; 1. The field work: In this stage, the Total Station Nikon Nivo-5C was selected for the current study. This device was measured horizontal and vertical distance, elevations, and coordinates from a single set up. This data directly stored on memory. 2. The office work: In t
... Show MoreMoment invariants have wide applications in image recognition since they were proposed.
AA Abbass, HL Hussein, WA Shukur, J Kaabi, R Tornai, Webology, 2022 Individual’s eye recognition is an important issue in applications such as security systems, credit card control and guilty identification. Using video images cause to destroy the limitation of fixed images and to be able to receive users’ image under any condition as well as doing the eye recognition. There are some challenges in these systems; changes of individual gestures, changes of light, face coverage, low quality of video images and changes of personal characteristics in each frame. There is a need for two phases in order to do the eye recognition using images; revelation and eye recognition which will use in the security systems to identify the persons. The mai
... Show MoreObjective: To review and identify the major drivers for COVID-19 vaccine acceptance. Methods: A scoping review of studies of COVID-19 vaccine perceptions and barriers to using the COVID-19 vaccines. Two search engines, including PubMed and Google Scholar, were purposefully searched. Results: Eight studies from different countries were reviewed to categorize factors influencing people's acceptance of COVID-19 according to the Health Belief Model (HBM). Perceived susceptibility, and severity of the disease (COVID-19), in addition to perceived benefits of COVID-19 vaccination and "cues to action", can enhance vaccination acceptance. In contrast, perceived barriers to the COVID-19 vaccine can increase people's hesitancy to be vaccinated
... Show MoreBark fiber has high potential use for composite reinforcement in biocomposite material. The aim of this study is the mechanical properties of Bark fiber reinforced polester composite with varying fiber weight fraction (0% , 5% , 10% , 20%, 30% and 40%) hand lay-up technique which was used to prepare the composite , specimens for tensile , flexural and impact test according to the ASTM D638 , ASTMD790 , and Iso-179. The over all results showed that the composite is reinforced with Bark fiber at weight (10%) higher mechanical properties , and the composite showed improved mechanical (Flexural).
