In this study new derivatives of O-[2-{''2-Substituted Aryl (''1,''3,''4 thiadiazolyl) ['3,'4-b]-'1,'2,'4- Triazolyl]-Ethyl]-p- chlorobenzald oxime (6-11)have been synthesized from the starting material p-chloro – E- benzaldoxime 1.Compound 2 was synthesized by the reaction of p-chloro – E- benzaldoxime with ethyl acrylate in basic medium. Refluxing compound 2 with hydrazine hydrate in ethanol absolute afforded 3. Derivative 4 was prepared by the reaction of 3 with carbon disulphide, treated of compound 4 with hydrazine hydrate gave 5. The derivatives (6-11) were prepared by the reaction of 5 with different substitutesof aromatic acids. The structures of these compounds were characterized from their melting points, infrared spectroscopy

This work includes synthesis of sugar tetrazole derivative, D-ribose reacted with acetone in the presence of sulfuric acid H2SO4 to give 2, 3-O-isopropylidene-D-ribose (1). The Aldol condensation of (1) with formaldehyde in methanolic K2CO3 solution gave 2-hydroxymethyl (2, 3-O-isopropylidene-D-ribose)(2). Which was tosylated by Tosyl chloride in pyridine to yield compound (3), SN2 reaction of (3) with sodium cyanide in DMSO afforded compound (4). The [2+ 3] cycloaddition reaction of (4) with sodium azide gave the targeted compound (5). All prepared compounds have been characterized by: TLC, Specific rotation, Microelemental analysis and [FTIR and 1 H NMR spectroscopy]

Background :Chronic lymphocytic leukemia (CLL) is a low-grade B-lineage lymphoid malignancy. Both  Ki-67 which is a large nuclear protein associated with cell proliferation and Bcl-2 which is an anti-apoptotic protein which is associated with dysregulation of the intrinsic apoptotic pathway , were thoroughly investigated in many cancer patients particularly in hemopoietic malignancies .

Patients, materials and methods: This retrospective study was conducted from November 2009 to May 2010 , on fifty formaline fixed paraffin embedded blocks of CLL cases retrieved from Medical City Teaching Hospital ; their age range was 39-75 years along with twenty control cases with benign r

Background: Development of colorectal adenocarcinoma principally occurs via the adenoma- carcinoma sequence of a multiple step process of tumor progression. This results from an accumulation of genetic changes in cells of intestinal mucosa. The use of molecular biomarkers may further aid in determining the risk of changing to carcinoma.

Objectives: To evaluate the expression of Bcl-2 and Ki-67 in colorectal adenomas and correlate the observed levels with age, gender, histological

In this work, new kinds of blocking sets in a projective plane over Galois field PG(2,q) can be obtained. These kinds are called the complete blocking set and maximum blocking set. Some results can be obtained about them.

Introduction: COVID-19 vaccine have been indicated to successfully decrease the hazard for symptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection furthermore associated hospitalisations. Objective: To study the immune response among different types of SARS-CoV-2 vaccines. Methods: This study includes 100 vaccinated individuals (43 Sinopharm, 30 AstraZeneca and 27 Pfizer) with one or two doses from different health centres in Baghdad. During the period from April 2021 to the end of May 2021, SARS-CoV-2 IgG and SARS-CoV-2 IgM levels were detected using AFIAS-6 device depending on FIA (Fluorescence Immunoassay) technique. Results: 93% of the cases were positive for IgG levels, and negative in 7% case

Currently voting process is paper based form, by using voting card or paper; thus the counting method is done manually, which exhausts a lot of time. Obsolete votes may be possibly occurring. This paper introduced a system in which voting and counting is done with the help of computer. The election process would be easier, it saves time, avoid errors while counting and obsolete votes are reduced. Electronic voting (E-voting) system is a voting system in which the election related data is stored and handled digitally, it would become the quickest, cheapest, and the most efficient way to administer election and count vote it is considered a means to further enhance and strengthen the democratic processes in modern information societies. Th

Background: Atherosclerosis causes thickening of the artery walls. The intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of the development of coronary artery disease, atherosclerosis, and independently cardiovascular disease (CVD). Diabetes increased the risk of cardiovascular disease, also accelerates the common IMT progression. The Sonographic measurement of carotid intima-media thickness is used as a valid simple and noninvasive method for the assessment of atherosclerosis disease.

Also the ankle brachial index (ABI) is considered as a strong predictor for future cardiovascular events, and a golden standard for the diagnosis of peripheral arterial disease (PA

This study describes the preparation of new series of tetra-dentate N2O2 dinuclear complexes (Cr3+, Co2+, Cu2+) of the Schiff base derived from condensation of 1-Hydroxy-naphthalene-2-carbaldehyde with 2-amino-5-(2-hydroxy-phenyl)-1,3,4-thiadiazole. The structures of the ligands were identified using IR, UV-Vis , mass,  elemental analysis and 1H-NMR techniques. All prepared complexes have been characterized by conductance measurement, magnetic susceptibility, electronic spectra, infrared spectrum, theromgravimatric analysis (TGA) and metal analysis by atomic absorption. From stoichiometry of metal to ligand and all measurements show a octahedral geometry proposed for all complexes of the (Cr3+, Co2+, Cu2+). conductivity measurement shows t
