Donor–acceptor duality of the transition-metal-like B2core in core–shell-like metallo-borospherenes La3&[B2@B17]−and La3&[B2@B18]−

Stabilization of fullerene-like boron cages by transition metal encapsulation.

The stabilization of fullerene-like boron (B) cages in the free-standing form has been long sought after and a challenging problem. Studies that have been carried out for more than a decade have confirmed that the planar or quasi-planar polymorphs are energetically favored ground states over a wide range of small and medium-sized B clusters. Recently, the breakthroughs represented by Nat. Chem....

Spontaneous Mesenchymal to Epithelial Like Tissue Transition (MET) in a Long Term Human Skin Culture

In an attempt to isolate multipotent stem cells from foreskin in a long-term culture, we encountered an interesting phenomenon which was the conversion of the fibroblast dominant condition to epithelial-like tissue formation. However, the basic mechanism(s) which may be involved in this conversion is not clear. This study was designed to evaluate the cells protein secretion activity and examine...

On the Structure of Metric-like Spaces

The main purpose of this paper is to introduce several concepts of the metric-like spaces. For instance, we define concepts such as equal-like points, cluster points and completely separate points. Furthermore, this paper is an attempt to present compatibility definitions for the distance between a point and a subset of a metric-like space and also for the distance between two subsets of a metr...

The Role of Toll-Like Receptors in Breast Cancer

Breast cancer is highly prevalent worldwide. Treatment of this disease is a major global public health problem; therefore, numerous studies have explored new molecular profile helping for breast cancer therapy. Different risk factors are attributed to breast cancer; however, chronic inflammation and immune regulation are highly essential. Various molecules impact this context, including toll-li...
