Fluid Parameters

Background: Semen analysis measures ejaculate volume, pH, sperm count, motility, forward progression, and morphology. Although semen analysis is not a test for infertility, it is considered the most important laboratory test in the evaluation of male fertility. There are many factors affecting the seminal fluid parameters and testicular varicocele is one of them. Varicoceles are the most commonly seen and correctable male infertility factor. Varicocelectomy is a common operation performed for infertile males with clinical varicocele. The aim of study to evaluate the seminal fluid parameters changes after testicular varicocelectomy. Patients and Method: A prospective cohort study was done at the Al Sader Medical City in Najaf during the period from (March-October 2019). The study include 30 males with age between 18 and 32 years old who had a clinical varicocele. Seminal fluid analysis was done one before surgery and another one three months after surgery and compare between the two tests to evaluate the changes in the parameters was done, which include seminal fluid liquefaction, volume, color, PH, sperm concentration, motility and morphology. Results: There were 30 patients enrolled in this study with a mean age of 23.8 ± 3.36. Seminal fluid concentration was 19.1 ± 7.2 million/ml and it was significantly increased postoperatively by almost 84% than preoperative concentration to reach 35.1 ± 11.3 (P ≤ 0.001). The changes in progressive motile sperms’ percent improved after varicocelectomy but not reach the statistical significance (P≥0.935). The mean ± SD percent of normal morphology sperms percent preoperatively was 46.9 ± 22.9 %, and after operation, it elevated to 50.9 ± 18.6 (p value≥ 0.336 ).The patients is divided in to two subgroups (normospermic and oligospermic subgroup). Conclusion: There is a significant improvement in sperm concentration. While there is significant improvement in sperm concentration in oligospermic subgroup, so the infertile patient who has oligospermia with varicocele will get better outcome after varicocelectomy.

Background: Breast cancer is the most frequently diagnosed cancer among women in 140 of 184 countries worldwide.  The association between breast cancer survival and socio-demographic and pathologic factors has been widely studied in the developed countries. But scarce data is available from Saudi Arabia. We aimed to determine the overall observed one year and three years survival rate of female breast cancer patients and to investigate the factors affecting survival rate. Methods: Retrospective data was collected from the cancer center registry at King Fahad Medical City (KFMC) that included all women diagnosed with breast cancer between 1st January 2011 till 31st December 2012 and were followed to 31st December 2015 (cut off point for follow-up). Kaplan-Meier analysis was done to assess overall survival. The factors affecting survival rate such as age, histological type, tumor grade at diagnosis, metastases and treatment options were investigated using log rank test and Cox regression analysis. Results: The overall observed survival probability of the study population at 1, and 3 years was 95%, and 85%, respectively. The 3 year survivals for the younger (≤40 years), 41-50 years and older (50+ years) patients were 83.9%, 90.6% and 80.6% respectively, the differences not reaching statistical significance. There were statistically significant associations between three year survival and histological type of tumour, laterality, metastases and type of treatment by the univariate analysis log rank test. Conclusions: One and three-year survival rate of breast cancer at KFMC was 96% and 85% respectively. Investigating the factors affecting survival rate is one of the most essential means of improving cancer prognosis.

Comprehensive Study

In our initial publication on this subject1) we reported results demonstrating that contrast is the most important factor in producing the high image quality required for reliable image analysis. We also listed the factors which enhance contrast in order of the experimentally determined magnitude of their effect. The two most powerful factors affecting image contrast attainable with sheet film are beam intensity and KV. At that time we had only qualitative evidence for the ranking of enhancing factors. Later we carried out the densitometric measurements which led to the results outlined below.Meaningful evaluations of the cause-effect relationships among the considerable number of variables in preparing EM negatives depend on doing things in a systematic way, varying only one parameter at a time. Unless otherwise noted, we adhered to the following procedure evolved during our comprehensive study:Philips EM-300; 30μ objective aperature; magnification 7000- 12000X, exposure time 1 second, anti-contamination device operating.

Strength And Stiffness

Processing polymers from the liquid crystalline state offers several advantages compared to processing from conventional fluids. These include: better axial strength and stiffness in fibers, better planar orientation in films, lower viscosity during processing, low solidification shrinkage of injection moldings (thermotropic processing), and low thermal expansion coefficients. However, the compressive strength of the solid is disappointing. Previous efforts to improve this property have focussed on synthesizing stiffer molecules. The effect of microstructural scale has been overlooked, even though its relevance to the mechanical and physical properties of more traditional materials is well established. By analogy with the behavior of metals and ceramics, one would expect a fine microstructure (i..e. a high density of orientational defects) to be desirable.Also, because much microstructural detail in liquid crystalline polymers occurs on a scale close to the wavelength of light, light is scattered on passing through these materials.

A statistical review provides analysis of four years of speech therapy services of a suburban school system which can be used for comparison with other school system programs. Included are data on the percentages of the school population enrolled in therapy, the categories of disabilities and the number of children in each category, the sex and grade-level distribution of those in therapy, and shifts in case-load selection. Factors affecting changes in case-load profiles are identified and discussed.

Purpose Previous studies showed early production precedes late perception in Cantonese tone acquisition, contrary to the general principle that perception precedes production in child language. How tone production and perception are linked in 1st language acquisition remains largely unknown. Our study revisited the acquisition of tone in Cantonese-speaking children, exploring the possible link between production and perception in 1st language acquisition. Method One hundred eleven Cantonese-speaking children aged between 2;0 and 6;0 (years;months) and 10 adolescent reference speakers participated in tone production and perception experiments. Production materials with 30 monosyllabic words were transcribed in filtered and unfiltered conditions by 2 native judges. Perception accuracy was based on a 2-alternative forced-choice task with pictures covering all possible tone pair contrasts. Results Children's accuracy of production and perception of all the 6 Cantonese tones was still not adultlike by age 6;0. Both production and perception accuracies matured with age. A weak positive link was found between the 2 accuracies. Mother's native language contributed to children's production accuracy. Conclusions Our findings show that production and perception abilities are associated in tone acquisition. Further study is needed to explore factors affecting production accuracy in children.
