Development of Cationic Benzimidazole-Containing UiO-66 through Step-by-Step Linker Modification to Enhance the Initial Sorption Rate and Sorption Capacities for Heavy Metal Oxo-Anions.

Effective and rapid capture of heavy metal oxo-anions from wastewater is a fascinating research topic, but it remains a great challenge. Herein, benzimidazole and -CH groups were integrated into UiO-66 in succession via a step-by-step linker modification strategy that was performed by presynthesis modification (to give Bim-UiO-66) and subsequently by postsynthetic ionization (to give Bim-UiO-66-Me). The UiO-66s (UiO-66, Bim-UiO-66, and Bim-UiO-66-Me) were applied in the removal of heavy metal oxo-anions from water.

Exosomes are involved in total body irradiation-induced intestinal injury in mice.

Ionizing radiation-induced intestinal injury is a catastrophic complication in patients receiving radiotherapy. Circulating exosomes from patients undergoing radiotherapy can mediate communication between cells and facilitate a variety of pathological processes in vivo, but its effects on ionizing radiation-induced intestinal damage are undetermined. In this study we investigated the roles of exosomes during total body irradiation (TBI)-induced intestinal injury in vivo and in vitro.

[Taurine affects expression of ICAM-1, VCAM-1 by p38 pathway in hypoxic endothelial cells].

To investigate the effect of taurine(Tau) on ICAM-1, VCAM-1 by p-p38 pathway in bovine pulmonary artery endothelial cells(PAECs) and explore its mechanism of action. Generation 4-12 cells in primary cultures of PAECs were used in experiments and divided into five groups： control group, hypoxia(hyp) group, inhibitor(SB203580) group, treatment(Tau) group, and treatment+inhibitor(SB+Tau) group. The concentration of Tau：100 mmol•L⁻¹; p38 inhibitor SB203580： 20 μmol•L⁻¹; and the treatment time was 12 h.

[Effects of strontium ranelate on the expression of BMP-2 in the mid-palatal suture of rats during rapid maxillary expansion].

Purpose: To investigate the effects of strontium ranelate on the expression of BMP-2 during rapid maxillary expansion.

Methods: Thirty-six male 6-week- old male Wistar rats were selected. They were randomly divided into 3 groups.

Assessing changes in quality of life using the Oral Health Impact Profile (OHIP) in patients with different classifications of malocclusion during comprehensive orthodontic treatment.

Background: The objectives of this study were to investigated changes in OHRQoL among patients with different classifications of malocclusion during comprehensive orthodontic treatment.

Methods: Clinical data were collected from 81 patients (aged 15 to 24) who had undergone comprehensive orthodontic treatment. Participants were classified 3 groups: Class I (n = 35), II (n = 32) and III (n = 14) by Angle classification.

[Effect of pamidronate and ibandronate on orthodontic root resorption in rats].

Objective: To compare the effects of pamidronate and ibandronate on orthodontic root resorption.

Methods: Seventy-two 6-week-old female specific pathogen free (SPF) Wistar rats were selected to establish models for orthodontic tooth movement. The rats were randomly divided into three groups: the control group (C group), pamidronate group (Pm group) and ibandronate group (Ib group).
