Abstract Liver cancer with hepatocellular carcinoma a serious clinical illness that progresses quickly and has a bad prognosis because to increased malignancy. Fibrosis is the precursor of liver cancer, which progresses to cirrhosis and carcinoma Diethylnitrosamine (DEN) is a chemical molecule that has been used as a carcinogenic agent to promote cancer in test animals because of its strong carcinogenic potential. Herbal plants have long been used as inexpensive, effective alternatives to pharmaceuticals in various liver-associated complications, since they contain many bioactive compounds useful in liver disorders. Hibiscus tiliaceus L. (Malvaceae) contain various phytochemicals in the plant extracts such as Flavonoids, phenols, alkaloids, Tannins, Saponins, Quinones, Coumarine, Triterpenoids, glycosides and Steroids. Thus, has various health benefits, and have medicinal and therapeutic values, It could be a source of natural antioxidants, antimicrobials, hepatoprotective compounds, and antimutagenic effects. The study was designed To study the possible protective role of Iraqi Hibiscus tiliaceus L. ethanol leaves extract administered in two different doses on diethylnitrosamine induced liver carcinoma in male Wistar Albino rats. Rats utilized in this study were randomized into 4 groups (six rats per each group); Group I: (Control) Rats were administered oral daily dose of 1ml /kg/day of distilled water for 20 weeks; Group II: rats intraperitoneally injected with 70 mg/kg diethyl nitrosamine once per week for 10 continuous weeks; Group III: Rats were administered 250mg/kg of Iraqi Hibiscus tiliaceus L. ethanol leaves extract as chronic oral administration with food for 5 days per week for 20 weeks and subsequently intraperitoneal dose of diethylnitrosamine (70 mg/kg) once per week for 10 continuous weeks; Groups IV: Rats were administered 500mg/kg of Hibiscus tiliaceus L. ethanol leaves extract as chronic oral administration with food for 5 days per week for 20 weeks with subsequently intraperitoneal dose of diethylnitrosamine (70 mg/kg) once per week for 10 continuous weeks. The finding revealed that Iraqi Hibiscus tiliaceus L. ethanol leaves extract showed significant reduction (P<0.05) in malondialdehyde, alpha fetoprotein (AFP), alanine aminotransferase (ALT), and aspartate aminotransferase (AST), total bilirubin (TSB), pro-inflammatory cytokines include transforming growth factor beta (TGFβ), tumor necrosis factor alpha (TNFα) and significant elevation (P<0.05) of anti-oxidant enzyme superoxide dismutase (SOD) in dose dependent manner. In conclusion this study demonstrated that the chemoprotective role of Hibiscus tiliaceus L. ethanol leaves extract might be explained by; lowered levels of hepatic enzymes, pro-inflammatory cytokines, and antioxidant levels, as well as decreased levels of alpha fetoprotein (AFP), the gold standard for detecting hepatocellular carcinoma.
Production and characterization of methionine γ- lyase from Pseudomonas putida and its effect on cancer cell lines
Photoplethysmography (PPG) is a non-invasive optical technique that employs variations in light absorption produced by alteration in the blood volume in capillaries at the skin during the cardiac cycle. This study aims to understand factors related to PPG morphology; a hand-elevation, the study has modified blood flow to and from the finger was conducted in the laboratory. It is widely established that the position of the limb relative to the heart has an effect on blood flow in arteries and venous. Peripheral digital pulse wave (DPW) signals were obtained from 15 healthy volunteer participants during hand-elevation, and hand-lowering techniques wherein the right hand was lifted and lowered relative to heart level, while the left h

This research presents an investigation of the behavior of SCC under mechanical loading (impact loading). Two types of cement have been used to produce SCC mixtures, Ordinary Portland Cement (OPC) and Portland Limestone Cement (PLC), which reduces the emission of carbon dioxide during the manufacturing process. The mixes were reinforced with Carbon Fiber Reinforced Polymer (CFRP) which is usually used to improve the seismic performance of masonry walls, to replace lost steel reinforcements, or to increase column strength and ductility. Workability tests were carried out for fresh SCC. Prepared concrete slabs of 500×500×50mm were tested for lo

Show MoreTeachers' self-efficacy plays a very important role in the process of teaching English language, and teachers have primary role in determining what is needed or what would work best with their students. The sample consists of eighty-seven English language teachers in secondary schools in Baghdad/Kaarkh2. Self-efficacy questionnaire of fifteen items was constructed. Face, content validity and reliability were verified. Then, pupils' marks for the first semester were taken as their achievement.The main finding of the study indicates that:
English language teachers' self-efficacy has effect on their pupils' achievement.

This paper is focused on studying the effect of cutting parameters (spindle speed, feed and depth of cut) on the response (temperature and tool life) during turning process. The inserts used in this study are carbide inserts coated with TiAlN (Titanum, Aluminium and Nitride) for machining a shaft of stainless steel 316L. Finite difference method was used to find the temperature distribution. The experimental results were done using infrared camera while the simulation process was performed using Matlab software package. The results showed that the maximum difference between the experimental and simulation results was equal to 19.3 , so, a good agreement between the experimental and simulation results was achieved. Tool life w

properties of nickel(ii) phthalocyanine tetrasulfonic acid tetrasodium

on indium tin oxide (ITO-glass). The optical absorption spectra of
these thin films are measured. Present studies reveal that the optical
band gap energies of NiPcTs thin films are dependent on the
annealing temperatures. The optical band gap decreases with increase
in annealing temperature, then increased when the temperature rising
to 473K. To enhance the results of Uv-Vis measurements and get

This study aims to find out the effect of the mediator on scaffolding fourth yearstudent- teachers' teaching competencies and their self-efficacy. The present study combines scaffolding and self-efficacy by using a mediator on scaffolding students affects teaching competencies and selfefficacy and from the results of which the existence of student-teachers’ selfawareness was ensured as an effect of the same independent variable. The model affects their teaching competencies and led them to be aware of the needs of their pupils and themselves.
The purpose of this paper is to gain a good understanding about wake region behind the car body due to the aerodynamic effect when the air flows over the road vehicle during its movement. The main goal of this study is to discuss the effect of the geometry on the wake region and the aerodynamic drag coefficient. Results will be achieved by using two different shapes, which are the fastback and the notchback. The study will be implemented by the Computational Fluid Dynamic (CFD) by using STAR-CCM+® software for the simulation. This study investigates the steady turbulent flow using k-epsilon turbulence model. The results obtained from the simulation show that the region of the air separation behind the vehicle
