Background: The role of Human papillomaviruses (HPV) in the etiology of ovarian cancer remains unclear and the results are controversial. Several studies have verified the presence of HPV DNA in both malignant and benign ovarian tumors.
Objectives: Determine the percentage of detection of HPV high (16&18) and low risk types (6&11) in surface epithelial ovarian carcinoma compared to benign and control groups.
Materials And Methods: Molecular detection and genotyping of HPV DNA were performed in 76 ovarian tissue blocks by using in situ hybridization (ISH) technique for detecting and localization of high risk HPV (16 and 18) and low risk HPV (6&11) types.
Results: The presence of ISH signals for HPV DNA in benign group (71%) was higher than that found in malignant group (64%). HPV 16 was the most predominant type followed by HPV18, 6, and 11 respectively in both malignant and benign groups. High risk HPV were presented with low score and high intensity in both malignant and benign tumors. Low risk HPV types were detected in high score and intensity in benign tumors which significantly differed from that with malignant tumors, which revealed low score and low intensity. The percentage of co-infection of low risk HPV6&11 in benign group was higher (16.9%) than malignant group (7.1%). Only significant difference was found in combination of both high and low risk HPV types.
Conclusions: This finding reflects a possible role of HPV virus in the carcinogenesis of ovarian tumors. HPV infection may play a relative role in the pathogenesis of ovarian carcinomas or it could facilitate its progression.
In this work, an enhanced Photonic Crystal Fiber (PCF) based on Surface Plasmon Resonance (SPR) sensor using a sided polished structure for the detection of toxic ions Arsenic in water was designed and implemented. The SPR curve can be obtained by polishing the side of the PCF after coating the Au film on the side of the polished area, the SPR curve can be obtained. The proposed sensor has a clear SPR effect, according to the findings of the experiments. The estimated signal to Noise Ratio (SNR), sensitivity (S), resolution (R), and Figures of merit (FOM) are approaching; the SNR is 0.0125, S is 11.11 μm/RIU, the resolution is 1.8x〖10〗^(-4), and the FOM is 13.88 for Single-mode Fiber- Photonic Crystal Fiber- single mode Fiber (SMF-P

Show MoreGround penetrating radar (GPR) is one of the Remote Sensing methods that utilize electromagnetic waves in the detection of subjects below the surface to record Once the data were collected, it could be presented in map and 2D and 3D. GPR method was applied in detecting graves (Tel Alags archaeological) fact, within the administrative border to spend Rumitha can be challenging. Due to the sensitivity of these sites, the challenge is to explore the subsurface without disturbing the soil Some cemeteries are hundreds of years old. Often records are vague or incomplete and there may be serious doubt about the precise extent of a cemetery .GPR is the most practical way to sort out the site was to carry out a detailed grid survey.

Multipoint forming process is an engineering concept which means that the working surface of the punch and die is produced as hemispherical ends of individual active elements (called pins), where each pin can be independently, vertically displaced using a geometrically reconfigurable die. Several different products can be made without changing tools saved precious production time. Also, the manufacturing of very expensive rigid dies is reduced, and a lot of expenses are saved. But the most important aspects of using such types of equipment are the flexibility of the tooling. This paper presents an experimental investigation of the effect of three main parameters which are blank holder, rubber thickness and forming speed th

The aim of the present study was to estimate and compare the microleakage of pit and fissure sealant after various methods of occlusal surface preparation. Materials and methods: Thirty non-carious premolars extracted for orthodontic reasons were equally divided into three groups. In group one, occlusal fissures were opened with round carbide bur, in group two, occlusal surfaces of the teeth were cleaned with a dry pointed bristle brush and samples of group three were cleaned with a slurry of fine flour of pumice in water using rubber cup. Then fissures of all teeth were etched using 35% p
... Show MoreIncremental sheet metal forming is a modern technique of sheet metal forming in which a uniform sheet is locally deformed during the progressive action of a forming tool. The tool movement is governed by a CNC milling machine. The tool locally deforms by this way the sheet with pure deformation stretching. In SPIF process, the research is concentrate on the development of predict models for estimate the product quality. Using simulated annealing algorithm (SAA), Surface quality in SPIF has been modeled. In the development of this predictive model, spindle speed, feed rate and step depth have been considered as model parameters. Maximum peak height (Rz) and Arithmetic mean surface roughness (Ra) are used as response parameter to assess th

Patients and Methods: - A total of 106 outpatients were subjected for colonscopy. Carcinoma biopsies from patients with colorectal cancer tissue from patient with polyps and normal mucosa stool and blood from all patient and controls were cultured and identified for S.bovis.
Results: - The histopatholgical findings confirmed that 38 patients had colorectal carninoma, 27 patients with benign polyps and 41 with normal colonic mucosa. The faecal carriage rate of S.bovis was 15(39.5%) in patient with colorected cancer, 5(18.5%) in patients with polyp and 7(17.1%) in control.
Conclusion: -
We describe a large functioning non metastasizing ACC in 8 years old boy who presented with a history of precocious puberty noticed by his parents since 3 months .Ultrasound of the abdomen showed a large well defined right suprarenal mass with calcification and necrosis . MRI showed the mass to be hypojntense to liver on T1 and hyperintense to liver on T2, and dynamic CT scan revealed a large hetrogenous enhancing right suprarenal mass with calcification and necrosis , clear chest .Histopathology done after surgical removal reveal adrenocortical carcinoma,so we recommend to do an abdominal ultrasound to any child with precocious puberty because it is easy,cheap and non invasive , if any suprarena

Quantitative analysis of human voice has been subject of interest and the subject gained momentum when human voice was identified as a modality for human authentication and identification. The main organ responsible for production of sound is larynx and the structure of larynx along with its physical properties and modes of vibration determine the nature and quality of sound produced. There has been lot of work from the point of view of fundamental frequency of sound and its characteristics. With the introduction of additional applications of human voice interest grew in other characteristics of sound and possibility of extracting useful features from human voice. We conducted a study using Fast Fourier Transform (FFT) technique to analy

This research deals with what so called concept of The Human Model and how Iraqi Media concerns of this concept practically as it plays a key role in attracting readers, on the first hand. On the second, it is important to shed light on the scientific desire of the Iraqi Media and how it deals with this contemporary trend especially in editorial media.
The importance of the research stems from the fact that it alerts to a new stream of modern trends in journalistic writing, according to many modern Arab and foreign media studies; and to the importance of employing human modeling in dealing with facts, events, issues and problems in various editorial arts within their effective influence in concilia
