Introduction: Since the hallmark of gestational trophoblastic disease is trophoblastic proliferation, Ki67 is regarded as the best marker in studying hydatidiform mole.This study was conducted to evaluate the role of this proliferative marker in distinguishing among hydropic abortion, partial and complete hydatidiform mole. Materials and methods: This is a cross sectional study involving the application of Ki67 on a total of 90 histological samples of curetting materials from molar (partial and complete mole) and non molar hydropic abortion belong to Iraqi females, so three study groups were created. Immunohistochemical expression in villous cytotrophoblasts, syncytiotrophoblasts and stromal cells were recorded separately by three independent observers and the results were correlated statically. Results: The mean number of stained nuclei of villous cytotrophoblasts and stromal cells was the highest in complete mole and the lowest in non molar hydropic abortion. There is a significant statistical relationship regarding Ki67 labeling index in villous cytotrophoblasts between partial moles and hydropic abortion, complete mole and partial moles, hydropic abortion and complete mole. Regarding Ki67 labelling index in villous stromal cells, a significant statistical relationship achieved when the correlation done between partial mole and hydropic abortions, hydropic abortion and complete mole, while a non significant statistical relationship was achieved if the correlation done between partial and complete mole. All villous syncytiotrophoblasts showed negative results. Conclusion: Ki-67 labeling index in villous cytotrophblastic cells are useful in separating between partial moles and hydropic abortion, partial mole and complete mole, hydropic abortion and complete mole. While Ki-67 labeling index in villous stromal cells is only useful in separating between partial moles and hydropic abortion, hydropic abortion and complete mole.

... Show MorePreparation of identical independent photons is the core of many quantum applications such as entanglement swapping and entangling process. In this work, Hong-Ou-Mandel experiment was performed to evaluate the degree of indistinguishability between independent photons generated from two independent weak coherent sources working at 640 nm. The visibility was 46%, close to the theoretical limit of 50%. The implemented setup can be adopted in quantum key distribution experiments carried out with free space as the channel link, as all the devices and components used are operative in the visible range of the electromagnetic spectrum.

Abstract
Objective(s): To determine the interventional program effectiveness on nurses' practices concerning diet instructions for orthopedic patients treated by internal fixation devices.
Methodology: A quantitative approach using prexperimental design is conducted to determine the effectiveness of an interventional program on nurses’ practices regarding orthopedic patients diet instruction and teaching after internal fixation implemented. The study has started from 1st of April 2022 and ended on 15th of December, 2022. The conduction of the study in Misan governorate / Al-Zaharawy surgical hospital. A non-probability, purpo

Azo compounds were prepared from the reaction of an ethanolic solution of sodium acetate and calculated amount of active methylene compound namely, acetyl acetone to obtain the corresponding hydrazono derivative (1). Cyclocondensation reaction of compounds (1) with hydrazine hydrate and phenyl hydrazine in boiling ethanol affording the corresponding pyrazoline-5-one derivatives of 4-aminobenzoic acid (2,3). Then compound (3) was reacted with thionyl chloride to give the corresponding acid chloride derivative(4), followed by conversion into the corresponding acid hydrazide derivative (5) carboxylic acid thiosemicarbazide (11), esters
