Published: April 2023

Vaginal candidiasis is a common complaint among women of different age groups in any society whether or not they are sexually active. Although it is both treatable and mild, when left untreated, The study was set to detect Candida organisms in women vaginal. A prospective study of women vaginal swabs collected from Gynecological Clinic in Azadi teaching Hospital and some privet clinical in Kirkuk city and a total of two hundred (200) women swab were analysed for microscopy and culture, from May 2014 to April 2015. Data on epidemiologic indices were collected from the patients, using structured interviewer-administered questionnaires. fifty- seven positive cultures were obtained, constituting 28.5% (n = 57) in a total of 200 women vaginal samples. A total of 28.5% (n= 57) isolates were detected which comprises four different Candida species, namely Candida albicans, C. glabrata, C. krusei and C. kefyre respectively as well as isolated Cryptococcus lorynti with frequency of occurrence of 23%, 2%, 1.5%, o.5% and 1.5% respectively. The isolates were related to age, the age range of 26-35 years had the highest incidence (35%), followed by age range of 36-45 years (29.5%) and 56-88 years had the least (2%) percentage of occurrence. The isolates were also related to used contraceptives, copper-T contraceptives and combined oral contraceptives 41.5% was the most common methods used by recurrent vaginitis patients while the male condom contraceptives users had lower cure (26.5%). The distribution of vaginal candidiasis according antibiotic using was highest in women take antibiotic with 64.4% of the total 200 cases, while the women don’t take antibiotic was recorded lowest occurrence (35.5%). The result shows that Candida species has assumed the role of the most common cause of vaginitis, with Candida albicans as the most prevalent species. vaginal candidiasis was common in the young adults o age range of 26-35 years, contraceptive , broad spectrum antibiotic users ,other diseases and operation .We therefore recommend prevention, early diagnosis and prompt treatment of vaginal candidiasis especially among the risk groups in order to avert its complications.

Diarrhea is a public health problem and an important cause of morbidity and mortality, enteroaggregative Escherichia coli (EAEC) have been recognized increasingly as agents of diarrhea in developing and in industrial countries. So the aim of this study is to study the prevalence of EAEC, its virulence factors and study it´s resistance to antibiotics. Results showed that E. coli represent 86 (32.9%) of the isolated bacteria. the high percentage 60% were EAEC, plasmid-encoded toxin (pet) was the marker most prevalent detected 14/30(28%) than EAST1(for EaggEC heat-stable enterotoxin 1)which detected in 9/30(18%) of EAEC and two virulence genes (pet+ and EAST1+) were found in7/30(14 %) of EAEC. 10% of isolates were contained capsule but only 3.3%isolates of E. coli have Type Ι pili while all the isolates possess Type ΙΙΙ pili. The results in the present study indicated that all E. coli were negative to Congo red dye agar test in contrast high percent of E. coli isolates were able to produce biofilm (86.7%) with different degree of thickness, while 20%isolates were urease positive after 24- 48 hrs, and 10% isolates were able to produce amylase. All isolates of E. coli were unable to produce Lecithinase, nuclease and hemolysin. While, 93.3% of E. coli isolates produced β-lactamase. The frequency of Sorbitol E. coli fermenter was 66.7%. In this study EAEC isolates were resistance (100%) to Penicillin and Ampicillin, High resistance(96.7%) was observed to each of Ceftriaxone, Cefotaxime and Trimethoprim. and Tetracycline (76.7%), resistance percentage of Both Amikacin and Rifampicin were (40%) and (33.3%) respectively. Higher sensitivity was reported to Gentamicin (63.3%), Ciprofloxacin(60%) then Nitrofurantoin (56.7%). The data from this study draw attention to the importance of notifying diarrheal disease. The high level of antimicrobial resistance observed in our study raises a broader discussion about the indiscriminate use or misuse of antibiotics and the risks of empirical antibiotic therapy in children of a very young age.

Verification Makhov,s profile for slow positron in Germanium
Authors: Sabah Mahmuoud Aman Allah  
Published: April 2023

In this paper the mean penetration depths z0 and Makhov (Implantation) profile I(z,E) were evaluated for low energies positrons(1.5-30/keV)by using a distribution function of Valkealahti - Nieminen for Germanium for different thicknesses:0.2, 0.4,0.8,1.2,1.4,1.6 μm. The obtained results reveals that the values of Makhov,s profile decreased exponentialy with increasing the positron energy and profile depths increasing linearly with increasing the incident energy. The shape of the Makhov,s profile reflects the shape of the energy spectrum of the positrons, which indicates the annihilation of positrons inside the material where its wavefunction is delocalized.

Published: April 2023

This study included preparing samples of the compound (Bi2Ba2Ca2Cu3O10+δ) by the solid state reaction method under a hydrostatic pressure 8 ton/cm2 and annealing temperature 840oC. X-ray diffraction (XRD), scanning electron microscopy (SEM), dc electrical resistivity measurements by four point probe method were used to investigate the microstructural and superconducting properties of Bi¬2223 samples. The X-rays diffraction study for the compound (Bi2Ba2Ca2Cu3O10+δ ) showed that it has Tetragonal type of crystal structure. The partial replacement of the component Ag in Bi, and Sr component in Ba simultaneously, the compound becomes (Bi2-xAgxBa2-ySryCa2Cu3O10+δ) with (x ,y) values equal to (x= 0.2, y= 0.1, 0.2, 0.3,0.4). The study of the crystal structure test showed that the structure retains on the tetragonal type with a high Tc phases (2223), low Tc phase(2212) and impurity phases, and the critical temperature Tc steps-up from (125K) to (137K) at substitution rate (x= 0.2, y= 0.1). But at increasing the substitution rate for (y) and the stability of (x) rate more than (x= 0.2, y= 0.1), the temperature declines to (108 K). Finally, the microstructural of the samples has been studies and tested by Scanning Electron Microscope for knowing the components' rates in the compound; how the compound partial substitution affect in the components; and specifying the quantitative and qualitative rates of the components in the compound.
