The light therapy is experiencing an unusually fast growth period, attracting the attention of numerous investigators. Having appeared only 5-6 years ago, this method could not yet give unshakeable conclusions and accurate illustrations. The author distinguishes three categories of light therapy: treatment by warm light, cold light, and colored light.

Growth Experiments

Tobacco-specific nitrosamines (TSNAs) are harmful carcinogens, with nitrate as a precursor of their formation. Nitrate content is considerably higher in burley tobacco than in flue-cured tobacco, but little has been reported on the differences between types of nitrate accumulation during development. We explored nitrate accumulation prior to harvest and examined the effects of regulatory substances aimed at decreasing nitrate and TSNA accumulation. In growth experiments, nitrate accumulation in burley and flue-cured tobacco initially increased but then declined with the highest nitrate content observed during a fast-growth period. When treating tobacco crops with molybdenum (Mo) during fast growth, nitrate reductase activity in burley tobacco increased significantly, but the NO3-N content decreased. These treatments also yielded significant reductions in NO3-N and TSNA contents. Therefore, we suggest that treatment with Mo during the fast-growth period and a Mo-Gfo (Mo-glufosinate) combination at the maturity stage is an effective strategy for decreasing nitrate and TSNAs during cultivation.

Abstract Objective This study evaluated developmental stages and trends of Total Healthcare Expenditure (THE) of 18 provinces in China. We explored characteristics of different development stages during healthcare expenditure, to provide scientific reference for China's healthcare policy making and regional healthcare planning.Methods Firstly, curve fitting and parameter estimation using SPSS21 software were carried out for the Logistic function model, and then the three-point or four-point method was applied to estimate the value of saturation K. Finally the Logistic function equation and fitting graph were obtained. According to the nature of Logistic curve, the study divided THE into three stages, gradual, rapid and slow growth, and predicted and analyzed THE developments in 18 provinces.Results By 2019, 15 provinces have entered a period of rapid THE growth. Regionally, the time to enter fast growth period early to late are in the order of northeast ( in 2005), east China ( in 2008), northwest ( in 2010), south China ( in 2013), north China ( in 2015) and southwest ( in 2015). The earliest province to enter rapid growth period is Liaoning province (in 2005), Shandong province enter the period at latest (in 2045). In 2027, all 18 provinces will enter the rapid growth period, and end in 2045. In this period, rapid growth in total health expense will last for about 23 years, with an average annual growth rate of 8.69%. Conclusions THE growth pattern is in line with typical trend of "slow-fast-slow" growth function. The expense developments vary between regions. Eastern region entered rapid and slow growth period later than the central and western regions. THE development stages and duration of the rapid growth period is correlated to regional economic level. The earlier it enters the fast growth period, the shorter it lasts, and vice versa. The government should take advantage of this period, from 2015 to 2029, to make policy preparations to respond THE rapid growth in China.

Heterogeneous Chemical Reactions

In vitromicrotubule assembly exhibits a rhythmic phenomenon, that is, fast growth periods alternating with slow growth periods. Mechanism underlying this phenomenon is unknown. Here a simple diffusion mechanism coupled with small diffusion coefficients is proposed to underlie this phenomenon. Calculations based on previously published results demonstrate that such a mechanism can explain the differences in the average duration of the interval encompassing a fast growth period and a slow growth period inin vitromicrotubule assembly experiments in different conditions. Because no parameter unique to the microtubule assembly process is involved in the analysis, the proposed mechanism is expected to be generally applicable to heterogeneous chemical reactions. Also because biological systems are characterized by heterogeneous chemical reactions, the diffusion-based rhythmic characteristic of heterogeneous reactions is postulated to be a fundamental element in generating rhythmic behaviors in biological systems.
