Colorectal cancer (CRC) is the most common disease and cause of death globally. The aim of the study is investigation and detection of some bacterial interfering with CRC occurrence and progression. The study conducted between September 2022 till February 2023, a total of 50 specimens were collected from confirmed CRC patients. In addition, 50 stool specimens were collected from Healthy volunteers, considers as control group. Isolation and identification of bacteria in all collected specimens were done by using cultural and differential media (blood agar, macconkey agar and Pfizer agar), as well as the VITEK- 2 compact system. The bacterial species, in the specimens of control were ( Escherichia coli 50 (86.20%), Klebsiella Pneumonia 3(5.17%), Salmonella typhi 2(3.44%), Staphylococcus aureus 1(1.72%), Proteus mirabilis 1(1.72%) and Pseudomonas aeruginosa 1(1.72%), while in the specimens of CRC and polyp were (Escherichia coli 30(38.69%), Streptococcus uberis 6(7.79%), Enterobacter cloacae 4(5.19%), Proteus mirabilis 11(14.28), Streptococcus constellatus pharyneis 1(1.29%), Micrococcus luteus 1(1.29%), Staphlococcus pseudintermedius 1(1.29%), Streptococcus thoraltensis 1(1.29%), Citrobacter freundii 1(1.29%), Streptoccus mutans 1(1.29%), Enterococcus faecium 5(6.49%), Enterococcus faecalis 4(5.19%), Granulicatella elegans 1(1.29%), Enterococcus gallinarum 2(2.59%), Serratia marcescens 1(1.29%), Streptococcus sangunis 1(1.29%), Staphylococcus lentus 1(1.29%), Comamons testosteroni 1(1.29%), Morganella morganii 1(1.29%), Pseudomonas aeruginosa 1(1.29%), Klebsiella pneumonia 2(2.59%). The bacteria which has been shown to be associated and more abundance in the specimens of CRC tissues are Escherichia.coli 30(38.96%), Streptococcus uberis 6(7.79%), Enterobacter cloacae 4(5.19%), Enterococcus faecium 5(6.49%), Enterococcus faecalis 4(5.19%). Cell-line culture techniques for the five species showed a cellular viability, sequentially Streptocccus uberis (16.12%), Enterococcus faecium (16.39%), Entreococcus faecalis (9.48%), Enterobacter cloacae (15.11%) and Escherichia coli (17.61%). The results statistically studied by using SPSS, which showed excellent or (highly) significant (p-value is in the range of 0.001).
In the presence of deep submicron noise, providing reliable and energy‐efficient network on‐chip operation is becoming a challenging objective. In this study, the authors propose a hybrid automatic repeat request (HARQ)‐based coding scheme that simultaneously reduces the crosstalk induced bus delay and provides multi‐bit error protection while achieving high‐energy savings. This is achieved by calculating two‐dimensional parities and duplicating all the bits, which provide single error correction and six errors detection. The error correction reduces the performance degradation caused by retransmissions, which when combined with voltage swing reduction, due to its high error detection, high‐energy savings are achieved. The res

Polyether ether ketone (PEEK) is a promising alternative to traditional dental implant materials like titanium, but its osseointegration capabilities are limited due to its hydrophobic nature and reduced surface roughness. Objective. The aim of the study is to increase the surface roughness and hydrophilicity of PEEK by treating the surface with piranha solution and then coating the surface with epigallocatechin-3-gallate (EGCG) by electrospraying technique. Materials and Methods. The study includes four groups intended to investigate the effect of pir

To achieve the aim of the present study, the researcher followed the following steps: preparing Philip Carter test for the spatial capacity which consists of (20) items on a group of (250) sixth scientific stage students in the directorates of Baghdad Education at Al–Rusafa (1st, 2nd and 3rd) for the academic year (2018-2019). Then, the researcher relied on a single-parameter model to analyze the data. The researcher used Bilog-mg3 model to check the hypotheses, data and match them with the model. In addition

Show MoreTeachers' self-efficacy plays a very important role in the process of teaching English language, and teachers have primary role in determining what is needed or what would work best with their students. The sample consists of eighty-seven English language teachers in secondary schools in Baghdad/Kaarkh2. Self-efficacy questionnaire of fifteen items was constructed. Face, content validity and reliability were verified. Then, pupils' marks for the first semester were taken as their achievement.The main finding of the study indicates that:
English language teachers' self-efficacy has effect on their pupils' achievement.
In the light of the findings of the present study, several conclusions, recommendations and suggestions for further
In the present study, silver nanoparticles (AgNPs) were prepared using an eco-friendly method synthesized in a single step biosynthetic using leaves aqueous extract of Piper nigrum, Ziziphus spina-christi, and Eucalyptus globulus act as a reducing and capping agents, as a function of volume ratio of aqueous extract(100ppm) to AgNO3 (0.001M), (1: 10, 2: 10, 3: 10). The nanoparticles were characterized using UV-Visible spectra, X-ray diffraction (XRD). The prepared AgNPs showed surface Plasmon resonance centered at 443, 440, and 441 nm for sample prepared using extract Piper nigrum, Ziziphus spina-christi, and Eucalyptus respectively. The XRD pattern showed that the strong intense peaks
Objective: The objective of the present study was to design and optimize oral fast dissolving film (OFDF) of practically insoluble drug lafutidine in order to enhance bioavailability and patient compliance especially for a geriatric and unconscious patient who are suffering from difficulty in swallowing.Methods: The films were prepared by a solvent casting method using low-grade hydroxyl propyl methyl cellulose (HPMC E5), polyvinyl alcohol (PVA), and sodium carboxymethyl cellulose (SCMC) as film forming polymers. Polyethylene glycol 400 (PEG400), propylene glycol (PG) and glycerin were used as a plasticizer to enhance the film forming properties of the polymer. Tween 80 (1% solution) and poloxamer407 were used as a surfactant, citri
