Background: There are several diseases in the body following recovery from COVID-19 infection because this virus operates on human genes in various types of peripheral tissue in the human body. It penetrates host cells via Angiotensin-converting enzyme-2 receptors and may have effects on bone remodeling, leading to osteopenia or osteoporosis, which are characterized by low bone mineral density, resulting in diminished bone strength. Bone Alkaline Phpsphatase is an enzyme released into the bloodstream as a soluble homodimer after being cleaved by a phospholipase and can be utilized as a biomarker of bone development.

Objective: This research was designed to investigate the alteration of bone homeos

This research has presented a solution to the problem faced by alloys: the corrosion problem, by reducing corrosion and enhancing protection by using an inhibitor (Schiff base). The inhibitor (Schiff base) was synthesized by reacting of the substrates materials (4-dimethylaminobenzaldehyde and 4-aminoantipyrine). It was diagnosed by infrared technology IR, where the IR spectrum and through the visible beams proved that the Schiff base was well formed and with high purity. The corrosion behavior of carbon steel and stainless steel in a saline medium (artificial seawater 3.5%NaCl) before and after using the inhibitor at four temperatures: 20, 30, 40, and 50 C° was studied by using three electrodes potentiostat. The corrosion behavior was

Diabetes mellitus can be defined as  a metabolic disorder disease .Complication  of diabetes  are due to diabetic nephropathy .This study was done in vitro to study the effect of different concentrations of erlotinib inhibitor ( tyrosine kinase inhibitor) on electrolyte levels (Mg⁺²,Ca⁺²,Na⁺) in sera of Iraqi patients with  newly diagnosis type2 diabetes and diabetic nephropathy in addition to find the best percentage inhibition for utilizing different concentrations from erlotinib (6.97x10⁻⁷, 9.30x10⁻⁷ ,1.16x10⁻⁶,1.39x10⁻⁶ ,1.62x10⁻⁵ )molar  on electrolyte levels . This study was conducted in The National Diabetes Ce

Total protein and total fucose were determined in sera of thyroid

disorder patients.

Sera of (40) diagnosed by consultant hyperthyroidism, and 40 hypothyroidism  were analyzed  for  the above  parameter  for  control, sera of (40) normal individuals were used.

They   were   healthy   with    no  appearing   disorder   results   analysis revealed  no significant  differences  (P<0.05)  in  the (mean  Â±SD)  of total   protein   values  in   sera  of   hyper  and   hypothyroidism   were compared

Introduction: An aneurysmal bone cyst are enigmatic lesion of unknown cause and presentation and are difficult to distinguish from other lesions, it is a benign, but expansible tumor like lesion that generally occurs in the long bones. An aneurysmal bone cyst arising from the flat bone like clavicle is rare . Case presentation: We report a 12-year-old girl child with an aneurysmal bone cyst of the lateral third of left clavicle treated with enblock resection. The pathologic findings confirmed the diagnosis of aneurysmal bone cyst. The patient has been followed up for one year with no evidence of recurrence . Conclusion: En bloc resection can be curative and provide good results for this rare type of clavicle tumour.

Carbohydrate antigen 19-9 (CA 19-9) levels were measured in sera and tissues of 40 patients with breast cancer (01), 8 patients with prostate cancer (G2)and 12 patients with thyroid cancer (G3), by the enzyme­ linked immunosorbent assay (ELISA) technique.

The patients were admitted to Medical City Hospitals (Baghdad Teaching Hospital and Nursing Home Hospital). The sera were taken just before surgery, where the specimens were taken immediately after surgery and kept in saline solution at -20°C until the time of homogenizing process.

The results of CA 19-9 levels in sera were (16.309±7.143; 31.281±0.766;

11.5±0.707 U/ml respectively compared with serum CA 19-9 level of control group G4 which was 7.74

The present study conducted on 30 female patients with osteoarthritis 0A a
attending Baghdad teaching hosp ital, in addition to 30 healthy females , all subjects
were ( 35-65) years old.
Some biochemical parameters were measured in the sera of patients and healthy
group s. The parameters were Glutathione (GSH). Ceruloplasmin (Cp) and some trace
elements ,including Copper (Cu) ,Cu/ Cp ratio and Selenium (Se) were determined . The
results revealed a significant reduction in all parameters of patients sera compared to
healthy group .
The reduction in GSH and Cu/Cp ratio confirms tissue damage associated with
oxidative stress injury
A conclusion was obtained hrer ,that Cu wasn’t an important ele

Background: Cardiovascular complications represent one of the consequences of chronic autoimmune diseases such as Systemic Lupus Erythematosus (SLE), which has significant rates of morbidity and mortality. Dyslipidemia can be brought on by steroid medications, which are frequently given to SLE patients and are considered to be one of the major risk factors for cardiovascular diseases.

Objectives: This study attempted to investigate a potential association between circulating vascular cell adhesion molecule 1 (VCAM-1) and intercellular adhesion molecule 1 (ICAM-1) as risk factors for atherosclerosis and their relationship to cardiovascular risk.

The research aims to shed light on the obstacles that hinder the use of taxpayers' commercial books covered by provisions of the amended commercial book-keeping system No. 2 of 1985 and ways to address these obstacles. On this basis, the main null hypothesis was formulated that there is no statistically significant relationship between the obstacles to the adoption of the commercial books and taxable income.

The research data were collected on the base of three applied case studies of registered taxpayers in the General Commission of Taxes, GCT, together with the use of a questionnaire distributed to a sample of taxpayers ( companies ). The collected data were analyzed, the result  were presented  and the hypothesis was
