Background: The immune antigen of Bacillus anthracis is a protein that can attach to the surface receptor of all human cells. At the surface of cancer cells, there is a receptor that activates the uPA (Urokinase plasminogen) that do not exist in normal human cells. Objectives: The aim of this study was changing the location of the attachment of the PA gene by a dir...

Background: Pectin is composed of complex polysaccharides that can inhibit cancer metastasis and proliferation with no evidence of toxicity. In the present study, the apoptotic and necrotic effects of pectic acid (PA) on the rat pituitary GH3/B6 tumor cells has been investigated. Methods: GH3/B6 cells were cultured in the Ham’s F12 medium enriched with 15% horse serum and 2.5% fetal bovine seru...

Let f be a computable function from finite sequences of 0’s and 1’s to real numbers. We prove that strong f -randomness implies strong f randomness relative to a PA-degree. We also prove: if X is strongly f -random and Turing reducible to Y where Y is Martin-Löf random relative to Z, then X is strongly f -random relative to Z. In addition, we prove analogous propagation results for other notion...

Let R be a notion of algorithmic randomness for individual subsets of N. We say B is a base for R randomness if there is a Z >T B such that Z is R random relative to B. We show that the bases for 1-randomness are exactly the K-trivial sets and discuss several consequences of this result. We also show that the bases for computable randomness include every ∆2 set that is not diagonally noncomputa...

We give an alternative proof of a result of Kučera and Slaman (2009, Lower upper bounds of ideals, Journal of Symbolic Logic, 74, 517–534) on low bounds of ideals in the 2 Turing degrees. This is a characterization of the ideals in the 0 2 degrees which have a low upper bound. It follows that there is a low upper bound for the ideal of the K-trivial degrees. Our proof is direct, in the sense th...

much of the research on family firms is carried out in mature markets, a small but burgeoning literature has examined the role of family businesses in emerging markets characterised by an institutional void. We examine publicly listed family firms in Taiwan to shed light on a key debate: is family control beneficial because it fills the institutional void or is it harmful because it abuses it. ...

Metabolic acidosis and severe hypotension are the main causes of irreversibility during hemorrhagic shock. The influence of these two factors on durations of shock period and survival time were studied in four groups of anesthetized cats. In group I the animals were made hypotensive by reducing mean arterial blood pressure (Pa) to 45 mmHg with concurrent metabolic acidosis. [n group II the ...

Background: Osteoarthritis (OA) is a progressive, age-associated disease that is characterized with cartilage destruction, subchondral bone remodeling and inflammation of the synovial membrane. Considering the complications of common treatments of OA, including non-steroidal anti-inflammatory drug (NSAIDs) and corticosteroids, investigating new treatments for this disorder is crucial. Recently,...

objective(s)bioelectrical impedance is the measure of impedance of the body. impedance consists of electric resistance and reactance. phase angle (pa) is the tan value of the ratio of reactance versus electric resistance. pa depends on cell membrane integrity and on body cell mass. there exists a correlation between pa values and body cell mass.the objective of this study was to compare the pa ...

introduction: in the present study, we hypothesized that a novel approach to promote vascularization would be to create injectable three dimensional (3-d) scaffolds within growth factor that enhance the sustained release of growth factor and induce the angiogenesis. material and methods: we demonstrate that a 3-d scaffold can be formed by mixing of peptide-amphiphile (pa) aqueous solution with ...
