The hematopoiesis in the bone marrow in the early stages of life is very complex and involves many cellular factors under very strict micro-environments. The two important cellular factors are heat shock proteins and antioxidant enzymes. The aim of the study was to study the gene expression profile of healthy rats’ bone marrow cells and niches particularly heat shock proteins and antioxidant genes. A total of thirty healthy Wister Albino rats at one, two, and three months old were involved throughout the study. Bone marrow samples were collected at a specified date according to the study design and utilized for qPCR test for expression of Hsps27, 90α, 90β, and antioxidant enzymes glutathione peroxidase1 (GPX1), catalase CAT and superoxide dismutase (SOD3) genes. The results revealed that there was a clear expression of both Hsps90α andβ in bone marrow cells throughout the study as well as the GPX1 gene. Furthermore, there was an increase in fold change of Hsps90α and β as well as GPX1, CAT, and SOD3 proteins as age progressed. In conclusion, hematopoietic cell differentiation and proliferation are regulated by bone marrow microenvironment stress conditions and by the expression of different Hsps and antioxidant genes. The protein folding process is a defense mechanism to protect the HSCs, and progenitors from un/misfolded proteins and to keep proteostasis.

Colloidal copper nanoparticles were prepared by pulsed (Nd:YAG,Q-switch) laser ablation in distilled water with a wavelength (1064nm) and frequency (1Hz) and the duration of the pulse was (10ns). Its purity is (99.9) immersed in distilled (deionized) water, where the metal target was first removed from copper placed in (5mL) of distilled water with a specific laser energy (260mJ) and for a number of fixed laser pulses (50, 100, 150) respectively. The size and optical properties of nanoparticles were characterized by transmission electron microscopy (TEM) and visible-UV spectrometry, respectively. eV) at the pulse (50) and (2.77eV) at the (100) and its value was (2.69eV) at the (150) pulse. The reason for the increase is due to the amount of material removal being greater. The results of the transmission electron microscope showed colloidal nanoparticles somewhat spherical and carnivorous, as depend on the size of the noble nanoparticles have gained wide popularity with many applications and fields, and the reason for this is due to the need for precise miniaturization of electronic devices and because of their unique character that differs from those in the usual case. Metal colloids are one of the important nano-sized materials.

Northern Technical University in Iraq relied in their education on the course system, which was marked by some kind of difficulties. A questionnaire was distributed to staff members including professors, technicians, administrators, administrators along with students subject to the curriculum system as a secondary source for collecting data and information. The study found that NTU as a modern university has an infrastructure supported by an electronic educational administrative information system. It provides an integrated digital platform for teachers to participate extensively in lectures, courses, scientific and practical workshops, create interactive lessons and assignments, tests and assessment through a solid. Such a platform could facilitate the students to complete their homework and academic duties in the time available to them. Students could be informed and notified by sending them an email that includes educational contents and details. This will definitely assist the university to keep using the course system. The study dealt with data analysis by using structural equation modeling technique and the confirmatory factor analysis strategy as a means to measure the observational variables represented by the digitization axes, which in turn matched the measures of statistical analysis Amos
