Oleanolic acid methyl ester, a novel cytotoxic mitocan, induces cell cycle arrest and ROS-Mediated cell death in castration-resistant prostate cancer PC-3 cells
Oleanolic acid derivatives exhibit potent anticancer activities against numerous types of cancer. However, the antitumor activity of oleanolic acid methylester (OAME), an oleanolic acid derivative, against prostate cancer has not been studied. Hence, the present work was conducted to study the anticancer activities of OAME. Viability assay showed that treatment of cancer cells with OAME induced a significant cell death ... Read more

Bactericidal and Antibiotics synergistic effect of Nanosilver against Methicillin-Resistant staphylococcus aureus.

Bactericidal and Antibiotics synergistic effect of Nanosilver against Methicillin-Resistant staphylococcus aureus.
ABSTRACT BACKGROUND: Methicillin-Resistant _Staphylococcus aureus _(MRSA) are bacteria responsible for several difficult-to-treat infections in humans. These strains have developed, through the process of natural selection. Infections by MRSA are more difficult to treat with standard types of antibiotics and thus more dangerous to human health. OBJECTIVES: The aim of this study was to evaluate the bactericidal and antibiotic synergistic effect ... Read more

A Novel Algorithm based on Entanglement Measurement for Improving Speed of Quantum Algorithms,

A Novel Algorithm based on Entanglement Measurement for Improving Speed of Quantum Algorithms,
In this paper, we draw attention to consider that the quantum entanglement measurement should be implemented as a key part during manufacturing the quantum processors and quantum micro-controllers. This paper aims to harness the complete power of quantum mechanics by the crossover between entanglement measurements and quantum gates to propose a novel quantum computer algorithms and protocols. One of these ... Read more

A Coupled Random Fixed Point Result With Application in Polish Spaces

2018-11-28 17:02:47 Keywords coupled random fixed point, ,
A Coupled Random Fixed Point Result With Application in Polish Spaces
In this paper, we present a new concept of random contraction and prove a coupled random fixed point theorem under this condition which generalizes stochastic Banach contraction principle. Finally, we apply our contraction to obtain a solution of random nonlinear integral equations and we present a numerical example. Read more

Morpho-Anatomical Characteristics of Olive (Olea europaea L.) Trees Leaf as Bio-indicator of Cement Dust Air Pollution in Libya

Morpho-Anatomical Characteristics of Olive (Olea europaea L.) Trees Leaf as Bio-indicator of Cement Dust Air Pollution in Libya
Comparisons were made between the anatomical and morphological changes in olive tree leaves from a site with relatively clean air (Al-Khadra area), and two sites (al-Khums and Zelatin) near to cement factories in the area east to Tripoli, Libya. Olive tree leaves exhibited marked variations in their morphological and anatomical characteristics, in relations to variations in the site cement dust ... Read more

Safety and efficacy of laparoscopic versus open surgery in management of common bile duct stones. Experience at Sohag university hospital.
ABSTRACT Background: Management of common bile duct (CBD) stones includes removal of the gallbladder and clearance of the ductal system which can be achieved through different approaches; endoscopic, laparoscopic or surgical. Objective of this study is to assess the safety, efficacy, technical feasibility and surgical outcomes of laparoscopic common bile duct exploration (LCBDE) versus open surgery in the treatment of ...
