DeepS: Accelerating 3D Mass Spectrometry Imaging via a Deep Neural Network.

Mass spectrometry imaging (MSI) is a powerful methodology that enables the visualization of the spatial distribution of biomolecules, including lipids, peptides, and proteins, from biological tissue sections. While two-dimensional (2D) MSI has been widely reported in various applications, three-dimensional (3D) MSI can enable the mapping of biomolecule distribution in complex biological structures (e.g.

Gastrointestinal Microbiota Changes in Patients With Gastric Precancerous Lesions.

Background: Gastric microbiota may be involved in gastric cancer. The relationship between gastrointestinal microbes and the risk of gastric cancer is unclear. This study aimed to explore the gastric and intestinal bacteria associated with gastritis and gastric precancerous lesions.

Development and Validation of Nomograms to Predict Operative Link for Gastritis Assessment Any-Stage and Stages III-IV in the Chinese High-Risk Gastric Cancer Population.

It is very essential to diagnose gastric atrophy in the area with high prevalence of gastric cancer. Operative link for gastritis assessment (OLGA) was developed to detect the severity of gastric atrophy. The aim of this study was to develop and validate nomograms for predicting OLGA any-stage and stages III-IV in the Chinese high-risk gastric cancer population.

GLAGC: Adaptive Dual-Gamma Function for Image Illumination Perception and Correction in the Wavelet Domain.

Low-contrast or uneven illumination in real-world images will cause a loss of details and increase the difficulty of pattern recognition. An automatic image illumination perception and adaptive correction algorithm, termed as GLAGC, is proposed in this paper. Based on Retinex theory, the illumination of an image is extracted through the discrete wavelet transform.

The Diagnosis Performance of the TCM Syndromes of Irritable Bowel Syndrome by Gastroenterologists Based on Modified Simple Criteria Compared to TCM Practitioners: A Prospective, Multicenter Preliminary Study.

Purpose: Traditional Chinese medicine (TCM) including Chinese patent medicine has been widely used to treat irritable bowel syndrome (IBS). Syndrome differentiation is the essence of TCM. However, the diagnostic ability of gastroenterologists to detect TCM syndromes in IBS in China remains unknown.

In situ simulation of thin-layer dredging effects on sediment metal release across the sediment-water interface.

Dredging is widely applied to remediate contaminated sediments in aquatic ecosystems. However, the efficiency of thin-layer dredging for metal pollution control remains uncertain and even controversial. This study conducted an in-situ simulation experiment in Lake Taihu to investigate dredging effects on sediment metal release based on metal fractions, diffusion flux and kinetics parameters of metal resupply, using diffusive gradient in thin films (DGT), multi-microelectrode, and European Community Bureau of Reference (BCR) sequential extraction scheme.

Dramatic source-sink transition of NO in the water level fluctuation zone of the Three Gorges Reservoir during flooding-drying processes.

Biogeochemical cycling of nitrous oxide (NO), a significant greenhouse gas (GHG), can influence global climate change. The production and emission of NO mediated by hydrological regimes is particularly active in water level fluctuation zones (WLFZs). However, the hydrological mechanisms affecting NO transformation and production across the water-sediment micro-interface remain unclear.

[Clinical efficacy and quality of life evaluation of BPPV by different reduction methods].

Objective: Comparative analysis of the clinical curative effect of manipulative reduction and TRV- CRP treatment of BPPV, comfort degree during reset and quality of life improvement.

Method: One hundred and thirty-two patients with BPPV were randomly divided into two groups ,one group underwent the traditional manip- ulative reduction, the other group with TRV-CRP. DRI and VAS was evaluated in the pre and after treatment and evaluation of the efficacy was conducted.

Bronchogenic cyst in the hepatogastric ligament masquerading as an esophageal mesenchymal tumor: a case report.

Lesions occur in hepatogastric gap is common, but most of these lesions are from stomach, lower esophagus and pancreas lesions extending or transferring to the gap. Lesions occurred in the hepatogastric ligament are rare, especially bronchogenic cysts in the hepatogastric ligament. So far, there were no relevant cases reported.
