Molecular investigation of evaporation of biodroplets containing single-strand DNA on graphene surface.

In this study, the water droplet behaviour of four different types of single-strand DNA with homogeneous base sequence on a graphene substrate during evaporation of the droplet was investigated using molecular dynamics (MD) simulation. The simulation results indicated that the evaporation depended on the DNA sequence. The observed changes can be divided into four parts: (i) vaporization mode, (ii) evaporation flux, (iii) mechanism of single-strand placement on the surface, and (iv) consideration of remaining single strands after evaporation.

Effects of Six Weeks of β-alanine Administration on VO(2) max, Time to Exhaustion and Lactate Concentrations in Physical Education Students.

Objectives: Supplementation with β-alanine has been proposed to improve performance in some exercises such as cycling and running. Also, it has been demonstrated that great deals of proton ions are produced in the skeletal muscles during exercise that result in acidosis, whereas β-alanine may reduce this effect. Therefore, the aim of this study is to assess the effects of alanine supplementation on VO(2) max, time to exhaustion and lactate concentrations in physical education male students.
