[Free gingival graft for augmenting peri-implant keratinized mucosa].

Insufficient keratinized mucosa is a common clinical problem. Although there is no consistent data on the long-term success of implant restorations relative to the presence or absence of peri-implant keratinized mucosa, it is widely accepted that the presence of keratinized mucosa width<2 mm is associated with increased biofilm accumulation, soft-tissue inflammation, and mucosal recession. Free gingival graft (FGG) is the standard surgical intervention for augmenting the width of keratinized gingiva.

Combining Electrosorption and Electrochemical Reduction Mechanisms for Uranium Removal Using 1,2,3,4-Butane Tetracarboxylic Acid-Modified MIL-101: An In-Depth Exploration of Uranyl-Adsorbent Interactions.

Extracting uranium from nuclear wastewater is vital for environmental and human health protection. However, despite progress in uranium extraction, there remains a demand for an optimized adsorbent with improved capability, efficiency, and selectivity. To bridge this gap, 1,2,3,4-butane tetracarboxylic acid (BTCA)-modified MIL-101 was synthesized through a simple hydrothermal reaction between amino-modified MIL-101 (MIL-101-NH) and BTCA.

Effect of neuromuscular electrical stimulation combined with respiratory rehabilitation training on pulmonary rehabilitation in patients with chronic obstructive pulmonary disease.

Objective: the study aimed to analyze the therapeutic effects of neuromuscular electrical stimulation (NMES) combined with respiratory muscle training (RMT) on patients with moderate-to-severe chronic obstructive pulmonary disease (COPD).

Methods: 135 patients with moderate/severe chronic obstructive pulmonary disease were selected as the research object and randomly selected. 72 cases were divided into rehabilitation group and 63 cases in control group.

Hierarchical Iontronic Flexible Sensor with High Sensitivity over Ultrabroad Range Enabled by Equilibration of Microstructural Compressibility and Stability.

Despite improved sensitivity of iontronic pressure sensors with microstructures, structural compressibility and stability issues hinder achieving exceptional sensitivity across a wide pressure range. Herein, the interplay between ion concentration, mechanical properties, structural geometry, and aspect ratio (AR) on the sensitivity of lithium bis(trifluoromethanesulfonyl) imide/thermoplastic polyurethane (LiTFSI/TPU) ionogel is delved into. The results indicate that cones exhibit superior compressibility compared to pyramids and hemispheres, manifesting in an enhanced sensitivity toward the LiTFSI/TPU ionogel.

Microbial community structure and water quality performance in local scrubber reclaim system for water reclamation of the semiconductor industry: a case study of a semiconductor plant in Beijing.

The local scrubber reclaim (LSR) system plays a critical role in water reclamation and in reducing environmental pollution emissions in semiconductor factories. This study monitored the changes in water quality and assessed the key stages of pollutant removal, with a primary focus on evaluating microbial growth and the shifts in microbial community structure and function in the LSR system. The results showed that activated carbon filtration (ACF) effectively removed total organic carbon (TOC) with a removal rate of 59.
