In recent years, the microbiota-gut-brain axis has attracted considerable attention within the field of AD.

Wnt/β-catenin signalling, epithelial-mesenchymal transition and crosslink signalling in colorectal cancer cells.

Colorectal cancer (CRC), with its significant incidence and metastatic rates, profoundly affects human health. A common oncogenic event in CRC is the aberrant activation of the Wnt/β-catenin signalling pathway, which drives both the initiation and progression of the disease. Persistent Wnt/β-catenin signalling facilitates the epithelial-mesenchymal transition (EMT), which accelerates CRC invasion and metastasis.

[Design and application of a new transoral gastric tube for extraction and storage of gastric contents].

Difficulty in swallowing is a common symptom in stroke patients, and nasogastric tubes are routinely used to solve the nutritional support problem of these patients. The existing nasogastric tube have the disadvantages of causing aspiration pneumonia and patient discomfort. The traditional transoral gastric tube has no one-way valve switch and gastric content storage device, and cannot be fixed in the stomach, resulting in reflux of gastric contents, inability to fully understand the digestion and absorption of gastric contents, and accidental dislocation of the gastric tube, affecting further feeding and gastric content detection.

Diffuse malignant peritoneal mesothelioma: A review.

Diffuse malignant peritoneal mesothelioma (DMPM) is an unusual and life-threatening locally invasive tumor. The morbidity and mortality of the disease are associated with progressive local effects in the abdominal cavity, such as abdominal distention, painful sensations, and early saturation with reduced oral intake, which eventually lead to intestinal obstruction and cachexia. Computed tomography (CT) has been widely used as a first-line diagnostic tool for DMPM.

Stress in Regulation of GABA Amygdala System and Relevance to Neuropsychiatric Diseases.

The amygdala is an almond-shaped nucleus located deep and medially within the temporal lobe and is thought to play a crucial role in the regulation of emotional processes. GABAergic neurotransmission inhibits the amygdala and prevents us from generating inappropriate emotional and behavioral responses. Stress may cause the reduction of the GABAergic interneuronal network and the development of neuropsychological diseases.

Neural Mechanisms With Respect to Different Paradigms and Relevant Regulatory Factors in Empathy for Pain.

Empathy for pain is thought to activate the affective-motivational components of the pain matrix, which includes the anterior insula and middle and anterior cingulate cortices, as indicated by functional magnetic resonance imaging and other methodologies. Activity in this core neural network reflects the affective experience that activates our responses to pain and lays the neural foundation for our understanding of our own emotions and those of others. Furthermore, although picture-based paradigms can activate somatosensory components of directly experienced pain, cue-based paradigms cannot.
