This communication describes a dynamic substrate that can selectively release immobilized ligands and hence can regulate, in real-time, the ligand ± receptor interactions between a cell and the substrate to which it is attached. The aim of this work is to provide model substrates for mechanistic studies of cell adhesion and migration. The adhesion of cells is mediated by the binding of cell-sur...

Recent studies have evaluated the impact of alternatives to antibiotic growth promoters (AGPs) such as phytogenic feed additives (PFAs) in vitro and in vivo. Zhou and colleagues studied the antibacterial properties of 30 herbs on pathogenic Gram-negative and positive bacteria (1). Thirteen of the 30 herbs exerted a significant effect against Escherichia coli ATCC 25922 (p < 0.01, n = 11 and p <...

KOIKE e t al. reported that a cationic acylpeptide antibiotic, colistin (polymyxin E) caused the formation of blebs on the outer layer of the Gram-negative bacterial cell envelope". They have also reported that colistin affects the cytoplasmic membrane, leads to leakage of cytoplasmic 260 nm-absorbing materials and has specific bursting-activity on spheroplasts of Gram-negative bacteria'). On t...

The first reported caffeine consumers in history were the members of the Galla tribe in Ethiopia, who were enjoying coffee 1000 years ago. In 1819 Friedlieb Ferdinand Runge isolated caffeine for the first time as a pure compound from coffee beans. The first total synthesis of caffeine was accomplished by Emil Fischer in 1895. Despite the extensive consumption of caffeinated nutrients in our dai...

Consumers are attracted to the latest fashion trends and different looks. This drives search for novel hair treatments. Some chemicals present in treatment products can penetrate shaft. These materials either nourish or injure cortex. Different techniques have been used investigate mechanism of molecule penetration conditions under which occurs. article reviews applied this purpose. Various mic...

Lipid membrane remodeling belongs to the most fundamental processes in body. The skin barrier lipids, which are ceramide dominant and highly rigid, must attain an unusual multilamellar nanostructure with long periodicity restrict water loss prevent entry of potentially harmful environmental factors. Our data suggest that acid mantle, apart from regulating enzyme activities keeping away pathogen...

•We investigate the importance of culture in achieving Sustainable Development Goals (SDGs)•Culture mediates attainment 17 SDGs, represented by 79% SDG targets•Cultural values explain as much 26% variations achievement SDGs•Sustainable policies can be tailored to, but not captive cultural context For a long time, sustainability science and policy design have been rooted environmental economic p...

Central MessageCurrent guidelines use aortic diameter as the primary metric guiding management of patients with thoracic aneurysms. Aortic length and, its surrogate volume, may ultimately prove better predictors AAEs.This Invited Expert Opinion provides a perspective on following paper: J Am Coll Cardiol. 2019 Oct 15;74(15):1883-1894. https://doi.org/10.1016/j.jacc.2019.07.078.See Commentaries ...
