Dissolved inorganic and organic phosphorus is a major factor in triggering the eutrophication of water bodies. At present, a novel Zr cross-linked sodium alginate encapsulated in Ce-UIO-66 microspheres (Zr-SA/Ce-UIO-66) was prepared and systematically characterized. Its ability for capture of phosphate and glyphosate in their single and binary systems has been investigated comprehensively.

Given their increasing environmental and health harms, it is crucial to develop green and sustainable techniques for scavenging antibiotics represented by oxytetracycline (OTC) from wastewater. In the present work, a structurally simple lanthanum-calcium dual crosslinked carboxymethyl chitosan (CMCS-La-Ca) aerogel was innovatively synthesized for adsorptive removal of OTC. It was found that CMCS and La sites collaboratively participated in OTC elimination, and OTC removal peaked over the wide pH range of 4-7.

Article Synopsis
  • Automatic segmentation of vertebrae in spinal x-ray images is important for clinical purposes but faces challenges due to low contrast and noise in x-ray images.
  • The study introduces a Multiscale Feature Enhancement Network (MFENet) that uses advanced techniques like a Dual-branch Feature Extraction Module and a Semantic Aggregation Module to improve feature extraction for better diagnosis of spinal diseases.
  • Experimental results show that MFENet outperforms other advanced methods in accurately segmenting spinal x-ray images, highlighting its effectiveness in clinical applications.

Antibiotics have been considered as a group of emerging contaminants for their stable chemical structure, significant pseudo-persistence, and biological toxicity. Tetracycline (TC), as one of the typical antibiotics frequently detected in environmental media, can cause the dissemination and accumulation of antibiotic resistance gene (ARG), ultimately threatening human health and environmental safety. Herein, a novel iron‑calcium di-crosslinked graphene oxide/alginate (GO/SA-Fe-Ca) aerogel was facilely synthesized for TC uptake.

Background: Upper extremity dysfunction after stroke is an urgent clinical problem that greatly affects patients' daily life and reduces their quality of life. As an emerging rehabilitation method, brain-machine interface (BMI)-based training can extract brain signals and provide feedback to form a closed-loop rehabilitation, which is currently being studied for functional restoration after stroke. However, there is no reliable medical evidence to support the effect of BMI-based training on upper extremity function after stroke.

Pregnancy is a special period marked with complicated changes in various immune responses. Although pregnant women are prone to developing gingival inflammation, its immunological mechanism remains to be clarified. In a modified ligature-induced periodontal disease murine model, pregnant mice developed more severe alveolar bone loss.

Although pregnant women are prone to gingival inflammation, its mechanism remains unclear. Animal models are ideal for investigating immunological mechanisms in the periodontal disease. A murine model for ligature-induced periodontal disease has been modified and utilized to determine the susceptibility to periodontal inflammation and tissue damage in pregnant mice.

Periodontitis is one of the most prevalent inflammatory diseases, characterized by gingival inflammation and alveolar bone loss. MicroRNAs (MiRNAs) are important regulators of inflammation and involved in periodontitis pathogenesis. In this work, we studied the roles of microRNA-21 (miR-21) in periodontitis.

Objectives: The aim of this study was to verify whether there is a difference in the in vivo performance characteristics of CBCT and periapical radiography (PR) in assessing the apical extension of root canal obturation (RCO) and to evaluate the ability of CBCT in void detection using microsurgical findings as validation.

Methods: This study included 323 tooth roots that required surgical treatment and for which pre-existing periapical radiographs and CBCT images were available. Three calibrated observers individually analyzed the periapical radiographs, CBCT images and photomicrographs of each root.

Objective: To assess referral cases for root canal therapy to provide clinical evidence with establishment of referral system.

Methods: A questionnaire was designed to collect 312 cases (355 teeth) referred to Department of Conservative Dentistry and Endodontics, West China School of Stomatology, Sichuan University for root canal therapy from April to June in 2011. The questionnaire consisted of questions such as age, gender, occupation, general disease and medical histories of patients, sources.

Introduction: This study evaluated the pathologic and spatial associations between apical periodontitis of the maxillary premolars/molars and the maxillary sinus mucosal thickening using cone-beam computed tomography (CBCT) scanning.

Methods: CBCT images of 372 patients with 508 exposed maxillary sinuses were inspected retrospectively. Clinical features such as sex and age of the patients and pathologic findings of the maxillary sinus and adjacent teeth were recorded, graded, and analyzed.
