Expressions of CD274 (PD-L1) and CD47 rReceptors on the sSurface of bBlast cCells in AML pPatients

     Acute myeloid leukemia (AML) is a genetically heterogeneous clonal disease defined by the proliferation and accumulation of immature hematopoietic cells in the bone marrow and blood. This study aimed to evaluate the CD47 and CD274 (PD-L1) expression in Iraqi AML patients and its role in the disease and evasion of malignant cells from immune system. The study was conducted on 85 patients diagnosed with leukemia, 25 of them were excluded as they had taken chemotherapy for less than a week and because the proportion of tumor cells was less than 20%. Virtually, it was conducted on 60 patients with AML and 20 healthy individuals as a control group.  The expression of CD47 and CD274 (PD-L1) was evaluated using flow cytometry in the peripheral blood of AML samples only.  Also MMP-2 level in serum was evaluated via ELISA in both AML and control samples. The expression of CD47 and CD274 in AML patients was found to be high. Analysis of CD274 (PDL1) expression in blast populations showed a significant increase in the proportion of CD274 (PD-L1) positive blast cells in isolated peripheral blood samples (66.3050 ± 1.94522). Also, the CD47 expression on blast cells in AML was recorded as significantly high (64.9333±2.05873). For MMP-2 (ng/ml) level in serum, the mean level non-significantly increased in AML as compared to the control group (102.677±8.719; 92.191±5.161) respectively.

A kinetic Study of the Rate Reaction of Alkaline Phosphatase in Tuberculosis

 Serum alkaline phosphatase activity has been investigated in three major types of tuberculosis (TB). These were Extra pulmonary primary, Acute miliary, and Primary tuberculosis. Activities were found elevated in these cases studied at basic PH and 37 C. The study concentrated an a comprehensive determination of the rate reaction kinetics of the enzyme reaction in both normal and TB sera. The pseudo first — order plot reflects both values of the first — order association constant (K I) and the half life time (t1/2) of the enzymatic reaction. The activation energy of the reaction (ES-complex formation) with Hill coefficient (n) were both estimated using Arrhenius and Hill plots respectively.

Some application of coding theory in the projective plane of order three

The main aim of this paper is to introduce the relationship between the topic of coding theory and the projective plane of order three. The maximum value of size of code over finite field of order three and an incidence matrix with the parameters,  (length of code),  (minimum distance of code) and  (error-correcting of code ) have been constructed. Some examples and theorems have been given.

Management of Retained Foreign Bodies in Missile Injuries of the Maxillofacial Region

This study evaluates 22 patients with retained foreign bodies in the maxillofacial region that were all caused by penetrating missile injuries. Surgical intervention for the retrieval of the foreign bodies was carried out in 20 patients through the existing wounds and through separate incisions; all patients were followed up for a minimum of 2 months during which all the complications were registered and managed. Preoperative imaging is a prerequisite for the accurate localization of the foreign body and the subsequent successful removal of it. All patients developed complications that were categorized in this study into those that result from the injury itself and those that occur because of the retrieval procedure, the latter category bei

Criticism of poetry in the book of mortality Ibn Khalkan (681 AH)

The researchers go to the classification of the book (mortality of objects) of Ibn Khalkan in the books of biographies, translations and history and consider it an important dictionary in translations and this is not disputed, but none of them did not reveal clearly about the literary phenomenon in which it is clearly related and the size of this phenomenon, it has come in the side This research sought to investigate this critical encyclopedia, which occupied a large area of ​​the historical framework of the book as we rarely found a figure in which did not turn - in extrapolation of translations - in the orbit of poetry as well as the great celebration of poetic speech during Translation has reached a number Perhaps the most promine

Comparison of Features Extraction Algorithms Used in the Diagnosis of Plant Diseases

      The detection of diseases affecting plant is very important as it relates to the issue of food security, which is a very serious threat to human life. The system of diagnosis of diseases involves a series of steps starting with the acquisition of images through the pre-processing, segmentation and then features extraction that is our subject finally the process of classification. Features extraction is a very important process in any diagnostic system where we can compare this stage to the spine in this type of system. It is known that the reason behind this great importance of this stage is that the process of extracting features greatly affects the work and accuracy of classification. Proper selection of

Economic Benefits for the Application of Standards of Sustainability in Construction Projects

In this research, that been focused on the most important economic benefits expected when applying the three standards of sustainability in construction projects (economic, environmental and social). Fuzzy AHP, a multi-decision decision-making technique for evaluating construction projects. Which when used we get the speed and accuracy in the results. Using this technique will reduce uncertainties decisions significantly (fuzzy environment), that found in most projects .The results of the data analysis showed  that the economic standards take the greatest relative importance (60%) among the three sustainability standards. Therefore, the implementation of any standards need a cost so the economic benefit of any proje

Effect of silver nanoparticles in the liver of female quail (Coturnix coturnix )

This study aimed to identify the alterations of liver in the quail (Coturnix coturnix) exposed by nanosilver particles.45 quail (females) were collected from agriculture research center in Abu-Ghraib, divided into (6) groups including: T1(12 quails were exposed to 4ppm), T2 (12 quails were exposed to 8ppm) and T3 (12 quails were exposed to 12ppm) of silver nanoparticles solution for 60 days. As well as three groups for control (3 females for each).

Effectiveness of Low Level Laser in the Treatment of Carpal Tunnel Syndrome

Background: Carpal tunnel syndrome (CTS) is one of common peripheral nerve disorder which involves an entrapment neuropathy of the median nerve at the wrist which occurs either due to primary idiopathic cause or secondary to systemic causes. The diagnosis of CTS is clinical and supported by neurophysiological analysis. Surgical intervention is the main treatment modality.
Objective: The aim of the present study is to evaluate the effectiveness of low level laser therapy (LLLT) to treat mild – moderate CTS cases.
Pateients and methods: The study involves 60 symptomatic patients complaining of CTS were divided into two groups. Group A was subjected to real LLLT by Gallium – Arsenide (Ga-As) laser (904 nm), whereas group B was sub

Evaluation of the Anti-inflammatory of Leucaena leucocephala extracts in Experimental Rats.

A lot of previous studies are concerned with the evaluation of the anti-inflammatory activity of medicinal plants because it considered cheap and are believed to possess minimal side effects. Leucaena leucocephala didn’t evaluate globally for its anti-inflammatory effect yet though some of it’s already separated and identified secondary metabolites were studied and proved to exert many pharmacological activities besides their effect on lowering the pro-inflammatory cytokines like TNF-α and IL-6. So, there was an interest to evaluate the biological effect of Leucaena leucocephala as a novel anti-inflammatory agent was the first motivation to start an in vivo study using a rat population. The N-butanol and ethyl acetate extracts were cho
