Genome-wide identification of the expansin gene family reveals that expansin genes are involved in fibre cell growth in cotton.

Background: Expansins (EXPs), a group of proteins that loosen plant cell walls and cellulosic materials, are involved in regulating cell growth and diverse developmental processes in plants. However, the biological functions of this gene family in cotton are still unknown.

Results: In this paper, we identified a total of 93 expansin genes in Gossypium hirsutum.

Chemical constituents from the rhizomes of Red. and anti-inflammatory activity in RAW264.7 macrophage cells.

Chemical investigation of the rhizomes of Red. led to the identification of 27 constituents. Among them, a total of 16 compounds were obtained from for the first time, in which, and were also firstly isolated as natural products.

[Export of Total Organic Carbon (TOC) from Karst Watershed and Its Influencing Factors: An Example from Xueyudong Underground River System, Chongqing].

High time-resolution auto-monitoring techniques were used to obtain the data for TOC and hydrogeochemistry of groundwater, and air temperature and precipitation from August 2014 to September 2015 in Xueyu Cave karst watershed, Southwest China, and then the principal component regression model was used to reveal the variation of TOC in groundwater and its influencing factors. The results indicated that there were significant variations of the TOC and hydrogeochemistry of groundwater in seasonal timescale. The temperature and specific conductance (SpC) of groundwater showed higher values in summer and lower values in winter; while an opposite variation pattern for pH in groundwater was observed, and the TOC and turbidity of groundwater showed higher values in winter and summer seasons and lower values in spring and autumn seasons.

Aromatase inhibitor letrozole in synergy with curcumin in the inhibition of xenografted endometrial carcinoma growth.

Objective: Endometrial carcinoma is a malignant tumor in the uterus. Its current treatment is not satisfactory. The present study aimed to promote the inhibitory effect on the implanted endometrial tumor growth.
