For more than a decade, human tissue-specific adult stem cells were known for their capacity to differentiate along their lineage of origin. However, over the recent years, numerous reports in the field of stem cell biology demonstrated that adult stem cells possess greater plasticity than what was previously dictated by established paradigms of embryonic development (De Kock et al., 2009, 2011...

Gastric cancer accounts for approximately 8% of new cancers worldwide (Jemal et al., 2011). Early diagnosis and accurate preoperative staging are critical for improving outcomes, and this includes the identification of the tumor location, depth of invasion, lymph node status, and the presence of metastasis (Monig et al., 2002; Chen et al., 2007; Makino et al., 2011). Current methods for the det...

Introduction Persistent organic pollutants (POPs) are ubiquitous and persist in the environment, accumulate in high concentrations in fatty tissues, and are biomagnified through the food chain. POPs include synthetic chemicals that were widely used as pesticides [e.g., dichlorodiphenyltrichloroethane (DDT), dichlorodiphenyldichloroethylene (DDE), hexachlorobenzene (HCB)] and in industrial proce...

The bottom–up approach is considered a potential alternative for low cost manufacturing of nanostructured materials [1]. It is based on the concept of self–assembly of nanostructures on a substrate, and is emerging as an alternative paradigm for traditional top down fabrication used in the semiconductor industry. We demonstrate various strategies to control nanostructure assembly (both organic ...

The aim of this study is to investigate consumer preferences and willingness to pay (WTP) for welfare friendly meat chicken products in Western Australia. Data from an internet-based choice experiment on skinless chicken breast is analysed to determine whether consumers care about humane production practices. Majority of respondents are concerned about the welfare of meat chickens. In general, ...

The question of how beaked whales are affected by naval sonar is important for the US Navy as information is required for accurate environmental assessments. A number of recent studies have reported behavioral responses of a small number of beaked whales to experimentally-presented sonar signals (Tyack et al., 2011; DeRuiter et al., 2013; Stimpert et al., 2014, Miller et al., 2015). These studi...

we present a modified version of the infeasible-interior- we present a modified version of the infeasible-interior-point algorithm for monotone linear complementary problems introduced by mansouri et al. (nonlinear anal. real world appl. 12(2011) 545--561). each main step of the algorithm consists of a feasibility step and several centering steps. we use a different feasibility step, which targ...

Cervical cancer is the third most commonly diagnosed cancer and the fourth leading cause of cancer death in the females worldwide, accounting for 9% (529,800 cases) of the total new cancer cases and 8% (275,100 deaths) of the total cancer deaths among females in 2008 (Jemal et al., 2011). More than 85% of these cases and deaths occur in developing countries (Jemal et al., 2011, Li et al., 2011)...

INTRODUCTION Planarians are capable of regenerating any missing body part and are an emerging system for investigation of cellular and molecular mechanisms underlying regeneration. Regeneration requires production of new cells and instructions that specify the identity of cell types to be regenerated. The planarian Schmidtea mediterranea utilizes a population of dividing regenerative cells call...

Freshwater turtles possess high hypoxia tolerance relating to their diving behaviour and ability to hibernate for several months without access to air (Jackson, 2000, 2002). While sustained cardiac function during hypoxia is essential for survival (Belkin, 1968), cardiac performance is markedly reduced and may depend on the high circulating levels of catecholamines during anoxia (White and Ross...
