Introduction/Aim. Roughly six percent of all malignancies diagnosed in children are malignant bone tumors. They have a dramatic effect on psychological status of children and their families. The aim of the study was to analyze the clinico-pathological features of bone tumors in Iraqi children and to assess response to treatment, outcome, and survival. Patients and methods. Over an eleven-year period, a retrospective study was done for children with bone tumors conducted on patients data that included a battery of pre-treatment investigations including a complete blood count, serum electrolyte, hepatic, and renal profile, bone marrow aspirate and biopsy, fine-needle aspiration, and imaging studies. Results. Data of 41 children with bone tumor were collected. The most common site of involvement was lower limbs, found in 21 (51.2%) cases. At the time of diagnosis, 29 patients presented with localized disease (70.7%), while 12 (29.3%) patients presented with metastasis. From 41 patients included in the study, histopathology of 29 (70.7%) patients was Ewing's sarcoma, whereas 12 (29.3%) patients were diagnosed with osteogenic sarcoma. The most common toxic effect of chemotherapy was febrile neutropenia which was recorded in 22 (59.5%) patients, followed by hemorrhagic cystitis in 3 (8.1%) patients; both febrile neutropenia and hemorrhagic cystitis were recorded in 5 (13.5%) patients, convulsion was found in 1 (2.7%) patient, and no complication were reported in 5 (13.5%) patients. Relapse was found in 8 (21.6%) patients. Conclusion. High rate of patients were lost to follow-up. Two-year event-free survival (EFS) was 53%, which is lower than that reported in other studies due to late diagnosis, late referral with the presentation in the locally advanced stage of disease.
In the field of research in the investment of gas fields, this requires that we first look at the center of the contracting parties in terms of the guarantee means granted to them under the contract, which constitute a means of safety and motivation to enter as major parties in the investment project. In turn, we will discuss the minimum guarantees, which are the most important guarantees granted to each of the two parties to the contract, namely the national party and the investor.

The image is divided into blocks, and each block has its authentication mark embedded in it, we would be able to insure which parts of the image are authentic and which parts have been modified. This authentication carries out without need to exist the original image. The results show the quality of the watermarked image is remaining very good and the watermark survived some type of unintended modification such as familiar compression software like WINRAR and ZIP
Staphylococci are common commensals in human beings, yet certain species are pathogenic. Staphylococcus aureus, particularly, is a very virulent human pathogen. The capacity of staphylococci to sense the density of bacterial cell, i.e., quorum, and thereafter respond via genetic modifications is attributable to one primary mechanism known as accessory gene regulator (Agr). Agr's extracellular signal is a peptide that is posttranslationally modified with a thiolactone molecule. Agr is in charge of the upregulation of numerous exotoxins and hydrolyzing enzymes, as well as the downregulation of many colonization determinants, under circumstances of high cell density. This modulation is critical for the scheduling synthesis of virul
