Purpose: To evaluate the frequency of visualization, thickness, and anatomical features of the normal appendix at nonenhanced helical computed tomography (CT).
Materials and methods : Two radiologists prospectively iterpreted, in consensus, the abdominal CT scans of 140 patients who were examined for renal colic assessment. They
were blinded to patients' surgical history regarding a previous appendectomy. No contrast material was used. The frequency of visualization, and the two – wall thickness of normal
appendix were recorded, as well as the anatomical features of the appendix and the effect of adequasy of intraperitoneal fat on identification of the appendix.
Results : The prevalence of appendectomy was 9% (13 of 140 patients). The sensitivity, specificity, positive and negative predictive values, and accurasy of visualization of normal
appendix were 77%, 85%, 98%, 27%, and 77% respectively. The frequency of visualization was lower in patients with less nintraperitoneal fat. The mean thickness of normal appendix
if no intraluminal content was visualized was 6.6 mm+ 1.0 mm, and the mean thickness excluding visualized intraluminal content was 3.6mm + 0.8 mm.
Conclusion : Most normal appendices are seen at nonenhanced helical CT. The thickness of normal appendix, when the content is not recognizable, overlaps the values currently used to
diagnose appendicitis at CT.
Background: In the present study used device jet plasma needle with atmospheric pressure which generates non thermal plasma jet to measure treatment potent with plasma against pathogenic bacteria founded in UTI was inactivated with plasma at 10 sec,

Non-hypertensive obese may have an elevated Morning Blood pressure surge (MBPS), which is associated with increased risk for cardiac events (CE) independently of office and ambulatory blood pressure (BP). Non-hypertensive obese also may have a blunted nocturnal decrease in BP during the night, while healthy normotensive non-obese individuals have a 10%–20% nocturnal decrease in blood pressure (BP) during the night or dipping. Thus, 24-hour ambulatory blood pressure monitor (ABPM) is the gold standard to evaluate MBPS and dipping profile in non-hypertensive obese individuals.

... Show MoreThe aim of this study is to propose reliable equations to estimate the in-situ concrete compressive strength from the non-destructive test. Three equations were proposed: the first equation considers the number of rebound hummer only, the second equation consider the ultrasonic pulse velocity only, and the third equation combines the number of rebound hummer and the ultrasonic pulse velocity. The proposed equations were derived from non-linear regression analysis and they were calibrated with the test results of 372 concrete specimens compiled from the literature. The performance of the proposed equations was tested by comparing their strength estimations with those of related existing equations from literature. Comparis

Numerical examples are presented to illustrate the applications of these method, and to compare the computed results with other known methods.
Background: Thyroid transcription factor-1 (TTF-1) is a protein that is well known to be expressed immunohistochemically in normal and neoplastic thyroid and pulmonary tissues. However; increasing studies have showed its expression in normal tissues and tumors of other organs including endometrium. These facts are important to be considered in the use of this marker in the differential diagnosis of carcinoma of unknown origin and make it important to use it as a part of a panel of immunohistochemical stains. In this setting Cytokeratin 7 and 20(CK-7&CK-20) are important since they have different coordinate expression profile in different organs and tumors.
Obejectives: This study is designed to assess
Background: Techniques of Inguinal hernia repair have seen an evolution from the pure tissue repair to the prosthetic repair and in the recent years past to laparoscopic repair. High recurrence rates using fascia for the hernia repair or the use of sutures under tension prompted the development of polypropylene mesh to reinforce the posterior wall of the inguinal canal.The aim of this study is to compare the post operative results of Lichtenstein mesh technique with Dar ning repair.<br />Patients and methods:-A prospective study of "100" patients with inguinal hernia were conducted to evaluate two methods, of open repair of inguinal hernia Lichtenstein mesh technique with Traditional non-mesh technique (modified Bassini or Darning)

Background: All though the most common etiology of lumbar radiculopathy is herniated disc or spinal stenosis, however there are several intraspinal or extra spinal pathogenic processes that may cause lumbar radiculopathy.
Objective: To assess how often, and review the pathologies that cause non discogenic lumbar radiculopathy.
Patients and Methods: A prospective study was conducted on 600 patients who had lumbar radiculopathy. During one year period we examined 600 patients in outpatient clinic with presumed diagnosis of lumbar disc herniation.Through history and comprehensive physical and neurological examination were performed for all patients. Diagnostic test were done including laboratory, electrophysiological and radiological
