Background: Breast cancer is the most common cancer in Iraq and the United Kingdom. While the disease is frequently diagnosed among middleaged Iraqi women at advanced stages accounting for the second cause of cancer-related deaths, breast cancer often affects elderly British women yielding the highest survival of all registered malignancies in the UK. Objective: To compare the clinical and pathological profiles of breast cancer among Iraqi and British women; correlating age at diagnosis with the tumor characteristics, receptor-defined biomarkers and phenotype patterns. Methods: This comparative retrospective study included the clinical and pathological characteristics of (1,940) consecutive female patients who were diagnosed with invasive breast cancer from 2014 to 2016 in Iraq (Medical City Teaching Hospital, Baghdad: 635 cases) and UK (John Radcliffe, Oxford and Queen's, BHR University Hospitals: 1,305 cases). The studied parameters in both groups comprised the age of the patient at the time of diagnosis, breast cancer histologic type, grade, tumor size, lymph node status, clinical stage at presentation, Estrogen Receptor (ER), Progesterone Receptor (PR) and HER2 positive tumor contents and the receptor defined breast cancer surrogate subtypes. Results: The Iraqi patients were significantly younger than their British counterparts and exhibited higher trend to present at advanced stages; reflected by larger size tumors and frequent lymph node involvement compared to the British (p<0.00001). They also had worse receptor-defined breast cancer subtypes manifested by higher rates of hormone receptor (ER/PR) negative, HER2 positive tumor contents, Triple Positive and Triple Negative phenotypes (p<0.00001). Excluding HER2 status, the significant differences in the clinical and tumor characteristics between the two populations persisted after adjusting for age among patients younger than 50 years. Conclusion: The remarkable differences in the clinical and tumor characteristics of breast cancer between the Iraqi and British patients suggest heterogeneity in the underlying biology of the tumor which is exacerbated in Iraq by the dilemma of delayed diagnosis. The significant ethnic disparities in breast cancer profiles recommend the prompt strengthening of the national cancer control plan in Iraq as a principal approach to the management of the disease.
Traumatic spinal cord injury is a serious neurological disorder. Patients experience a plethora of symptoms that can be attributed to the nerve fiber tracts that are compromised. This includes limb weakness, sensory impairment, and truncal instability, as well as a variety of autonomic abnormalities. This article will discuss how machine learning classification can be used to characterize the initial impairment and subsequent recovery of electromyography signals in an non-human primate model of traumatic spinal cord injury. The ultimate objective is to identify potential treatments for traumatic spinal cord injury. This work focuses specifically on finding a suitable classifier that differentiates between two distinct experimental

The imprinted polymers were prepared by polymerization of styrene (STY) as monomer, N,N methylene di acrylamide as a cross linker ,benzoyl peroxide (BPO) as an initiator and levofloxacin as a template. Di methyl adepate (DMA) and acetophenone (AOPH) were used as plasticizers , the molecular imprinted membranes and the non molecular imprinted membranes were prepared. The slopes and detection limits of the liquid electrodes ranged from -21.96 – -19.38 mV/decade and 2×10-4M- 4×10-4M, and Its response time was around 1 minute, respectively. The liquid electrodes were packed with 0.1 M standar

It is a recent study of the past and relying on it. Therefore, studying the history of sports for people with disabilities and their development is of great importance, as it is one of the means to measure the extent of development of societies and their culture in this field. Weightlifting is a sport for people with motor disabilities, and the way to play is for the contestant to lie on the bench (ping bar) and most often the legs are tied to the bench to ensure that the hip and legs do not contribute to the lifting process with the arms, when the player grabs t

For this reason, the researcher set three goals for the current research: identifying the level of social exclusion among people infected with the Coronavirus. The incubation period of the virus. Social exclusion and its relationship to the duration of incubation of the disease among people infected with the Coronavirus. The result showed that the research sample does not suffer from social exclusion. The mean value for the period from

The scientific value of the research stems from highlighting the importance of the dimensions of the quality of professional life in improving the productive efficiency of workers in the public sector and raising the level of organizational performance. Because the quality of working life plays an important role in enhancing the core competencies of employees in the public sector, it can also be an incentive or a disincentive for any employee by adapting to the economic and social condition

To solve the nature of the current problem, the two researchers used the descriptive approach of the survey method. The two researchers determined their research community by limiting the sample to all faculty members in the faculties of physical education and sports sciences in Baghdad (Al-Mustansiriya University, Al-Jadriya Univeristy & Al-Waziriyah University). Their number reached 314 faculty members and the two researchers determined their research community by 90%, so the research sam
