Background: Bowel cancer is the most prevalent digestive system cancer and is the 4th largest cause of cancer-related death worldwide. In Iraq, colon and rectal cancer (CRC) is the 6th most common malignancy in males and the 5th in females. This cancer is sluggish in growth, which gives a window of opportunity to screen for both precursor lesions and early cancer. The Cluster of Differentiation 47 (CD47) protein is a type of transmembrane glycoproteins found on nearly all human cells, including non-hematopoietic and hematopoietic cells. CD47 promotes CRC growth by triggering angiogenesis and apoptosis of tumor cell. Objectives: To evaluate the immunohistochemical expression of (CD47) in various colorectal samples from Iraqi patients with CRC by immunohistochemistry (IHC) assay. Specimens and methods: A total of 45 paraffin-embedded CRC tissue specimens and clinical data were obtained from the Medical City Teaching Hospital in Baghdad and a number of private laboratories in Baghdad, Iraq. In addition, 30 control colon and rectum tissues with no significant pathology were collected from the Forensic Medicine Department for comparison purposes after taking the official approvals. Results: The results revealed a high expression of CD47 in CRC cases, but with no significant correlation with clinicopathological features. Also, the result of figures in this study revealed negative membranous expression of CD47 (score 0), strong membranous expression of CD47 (score 3), moderately membranous expression of CD47 (score 2), and weak membranous expression of CD47 (score 1) Conclusion: Patients with CRC had high CD47 expression, allowing tumor cells to modulate CD47SIRP inhibitory signaling and prevent immune cell attack.
Chronic myeloid leukemia (CML) is a myeloproliferative disorders characterized by formation of Philadelphia chromosome. After disease development, several events may associate with the reduction of anti-tumor immunity. The present study was designed to investigate the immunological profile of innate and adaptive immune response in Iraqi patients with CML. Patients were grouped into untreated (UT), treated (T) with chemotherapy, while another apparently healthy individuals were recruited to represent the control (C) group. Methods: ELISA technique was used to estimate serum levels of GM-CSF, IL-1a, IL-8, IL2, INF-?, IL-4, and IL-10 while SRID was used to estimate serum levels of C4, IgM, IgA, and IgG. Results: Regarding to innate immune resp

Osteopenia is the preceding step to osteoporosis because it causes a decrease in bone mass, osteoporosis reduces a person's quality of life. Periostin (encoded by Postn), its name is derived from the fact that it was first detected in periosteal osteocytes and osteoblasts. Periostin deficiency has been linked to osteoporosis and weak bones. Study objectives: The purpose of this study was to determine periostin levels in serum of Iraqi patients with osteoporosis and osteopenia, and it is also possible to consider periostin as a diagnostic factor to follow the progression o

Show MoreBackground: Diabetic cheiroarthropathy is a term derived from the Greek word “cheiros” meaning “of the hand”, It is characterized by stiff hands with distinctively thick, tight, and waxy skin, especially on the dorsal aspects of the hands. It is part of long term complication of diabetes and many suggest it is associated with microvascular complication. The aim of the study was to determine the prevalence of diabetic cheiroarthropathy in Iraqi patients with diabetes, and to study its association with diabetic retinopathy and glycemic control. Material and Methods: A cross-sectional study in which 110 diabetic patients and 110 non-diabetic healthy people who accepted to take part in the study were ran

Show MoreBackground Several studies have addressed the prevalence of Toxoplasma gondii (T. gondii), among Parkinson’s disease (PD) patients in different countries, and the potential association between the infection and PD; the results of these studies were conflicting. The study aims to investigate the prevalence of Toxoplasma infection among sample of Iraqi PD patients. Also, to examine the potential association of age, PD duration, gender, smoking habit, zone of residence and family history of PD, with the prevalence of Toxoplasma infection in PD patients.

to be the most common metabolic disorder
associated with magnesium deficiency, and because
available data suggest that adverse outcomes are
associated with hypomagnesemia, it is prudent that
routine surveillance for hypomagnesemia be done
and the condition be treated whenever possible.
Aim of the study:To explore the serum Mg
concentrations of diabetic patients and healthy
controls in our locality.

With the growing number of patient’s being diagnosed with Parkinson’s disease and Multiple Sclerosis each year it is becoming ever more important to find the cause for these neurological disorders. The present study attempts to shed light on one of the factors that may play a role as a causative agent in these neurological diseases by finding a correlation between the Herpes simplex virus type 1 and 2 in patients with Parkinson’s disease and multiple sclerosis by detecting the virus in these patients using immunological techniques. Sixty patients with neurological diseases (40 patients with Multiple sclerosis and 20 patients with Parkinson’s disease) who’s ages ranged from (17-76) years have been investigated. Samples wer

Blood was taken with drawn sample from 30 obese normal patients with age range (40-60) years, 30 diabetic patients with age range (40-60) years at duration of disease (1-5) years and 30 normal healthy patients. The mean difference between T2DM according to CoQ10 (12.5±1.1) was decreased than the mean of IFG (21.8±3.2) (P 0.002) and the mean difference between T2DM according to IGFBPs (0.65±0.06) was decreased than the mean of IFG (3.2±0.3) (P 0.000). While no significant difference between mean age of DM2 patients (55.5±1.06), and IFG (55.6±0.9) (p 0.90), no significant difference bet

As the ability to aggregate is atributed to many factors such as the availability of macromolecules and plasma lipids, the role of plasm lipid profile on RBC aggregation and sedimentation changes in normal and diabetic patients is studied.Also serum lipid profile measurement (Total cholesterol, Triglyceride, HDL, LDL, VLDL) in normal and diabetic subjects were made. The principle of measurement includes detecting the transmitted laser light through a suspension of 10% diluted red blood cells in plasma. In all diabetics, the raulux formation and sedimentation rate is enhanced.
