Geographic differences in psychological symptoms, sleep quality, and quality of life in patients with inflammatory bowel disease: A multicenter study in China.

Objective: We aimed to explore the geographic differences in psychological symptoms, sleep quality, and quality of life (QoL) among adult patients with inflammatory bowel disease (IBD).

Methods: A unified questionnaire was developed to collect data on psychological status and QoL of IBD patients from 42 hospitals across 22 provinces, municipalities, and autonomous regions in China's mainland from September 2021 to May 2022.

Results: A total of 2478 patients with IBD were surveyed.

He-Ne laser pretreatment protects wheat seedlings against cadmium-induced oxidative stress.

The aim of the investigation is to determine the effect of He-Ne laser pretreatment of wheat seeds on the resistance of seedlings to cadmium stress. Changes in physiological, biochemical and molecular characters were measured. Our results showed that 150 μM Cd treatment significantly reduced plant height, root length, shoot fresh weight, shoot dry weight, root fresh weight, root dry weight, ascorbate acid (AsA) and glutathione (GSH) concentration, the activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), ascorbate peroxidase (APX) and gene expression levels of SOD, APX, enhanced the concentration of malondialdehyde (MDA), hydrogen peroxide (H(2)O(2)) and the rate of superoxide radical (O(2)(•-)) generation in the wheat seedlings when compared with the control.

Microwave pretreatment can enhance tolerance of wheat seedlings to CdCl2 stress.

In order to determine the role of microwave in cadmium stress tolerance of wheat (Triticum aestivum L.), seeds were exposed to microwave radiation for 0, 5, 10 and 15 s (wavelength 125 mm, power density 126 mW cm(-2), 2450 MHz), and when the seedlings were 7 d old (with one fully expanded leaves), they were treated with 150 μM CdCl(2) solution for 10 d. Changes in a number of physiological and biochemical characteristics were measured and used as indicators of the protective capacity of microwave radiation in this experiment.

[Structural development of root and their relationship to accumulation of triterpenoid saponins in Achyranthes bidentata Bl].

A study concerning the relationship of dynamic accumulation of triterpenoid saponins and anatomical characteristics of Achyranthes bidentata Bl roots was undertaken by anatomical, histochemical and phytochemical method respectively. Results revealed that the primary and secondary structures of the root resembled those of usual dicots. The continual thickening growth of root principally resulted from the differentiation and development of the tertiary structure.
