Pollinator shifts, contingent evolution, and evolutionary constraint drive floral disparity inSalvia(Lamiaceae): Evidence from morphometrics and phylogenetic comparative methods
(WILEY, 2020)Switches in pollinators have been argued to be key drivers of floral evolution in angiosperms. However, few studies have tested the relationship between floral shape evolution and switches in pollination in large clades. ... -
Preparation of a novel functionalized magnetic nanobiocomposite as a carrier for protein adsorption
(TAYLOR & FRANCIS INC, 2020)This study aims the synthesis of a novel functionalized magnetic nanocarrier based on xanthan gum biopolymer. Glycidyl methacrylate was grafted on xanthan gum chains by radical polymerization reaction using two types of ... -
Protective Effect of Aerobic Exercise on the Nasal Mucosa of Rats Against the Histopathologic Changes in Cigarette Smoke Exposure

Purifying selection shaping the evolution of the Toll-like receptor 2 TIR domain in brown hares (Lepus europaeus) from Europe and the Middle East
(SPRINGER, 2020)Toll-like receptors (TLRs) are transmembrane proteins of the innate immune system, composed of the ectodomain involved in pathogen recognition and the intracellular Toll/interleukin-1 receptor (TIR) domain important for ... -
Some Characterizations Of Generalized Null Mannheim Curves In Semi-Euclidean Space
(INST BIOPHYSICS & BIOMEDICAL ENGINEERING, BULGARIAN ACAD SCIENCES, 2020)In the present paper, we investigate Cartan framed generalized null Mannheim curves in the four-dimensional semi-Euclidean space of index two. We construct the Cartan (or Frenet) frames and curvature functions of generalized ... -
