Summary: This study found that the effects of intra-LHA NPY on caloric intake vary depending on the consumption of a fat or sugar component in a free-choice diet. The study also revealed that baseline preference for the fat diet component modulates the effects of intra-LHA NPY in rats fed with a free-choice high-fat and high-sugar diet.

Summary: Maintaining energy balance is crucial for survival and health. The brain receives various signals to regulate food intake based on energy needs. Microglial cell activation in the hypothalamus may affect energy balance, and nutritional lipids can play a role in this process.

Summary: Obesity-induced neuroinflammation is a chronic inflammation in the central nervous system characterized by increased pro-inflammatory cytokines and the activation of the NLRP3 inflammasome. It is caused by lifestyle changes such as excessive intake of obesogenic foods and decreased physical activity. Chronic lipid intake triggers neuroinflammation in multiple brain regions, affecting feeding control and leading to metabolic and neurological alterations.

Summary: This study investigates the use of mobility data in studying the relationship between dynamic food environments and diet-related health. The findings suggest that visits to fast food outlets can be a better predictor of individuals' obesity and diabetes risks than self-reported fast food intake.

Summary: CRTC1 in SF1 cells is a sensitive factor for high-fat diet-induced obesity, necessary for normal appetite regulation. It is primarily expressed in the brain, playing an important role in the ventromedial hypothalamus. RNA sequencing analysis of microdissected ventromedial hypothalamus samples revealed that the loss of CRTC1 significantly altered the expression levels of certain genes.

Summary: Long-term reductions in food intake, especially energy dense foods, have been found in individuals who underwent Roux-en-Y gastric bypass surgery. At 24 months post-surgery, overall energy intake decreased by 60%, with reductions seen across all food categories. The study also suggests a possible increase in the proportional intake of protein after surgery.

Summary: Prolonged exposure to a high-fat diet leads to hyperphagia and weight gain, but within a short period of time, caloric intake is regulated and energy balance is restored. Acute high-fat diet exposure activates brainstem astrocytes, increasing glutamatergic transmission to gastric-projecting neurons and restoring caloric balance. Inhibiting brainstem astrocytes reduces glutamatergic signaling, disrupts gastric tone and motility, delays gastric emptying, and prevents the decrease in food intake during energy regulation.

Summary: Histamine, a neuromodulator in the brain, contributes to the regulation of various physiological processes, including energy balance, through histaminergic signaling in the hypothalamus. Two histamine receptors, H1R and H3R, play important roles in key hypothalamic nuclei involved in energy homeostasis. Activation of H1R suppresses food intake, while activation of H3R stimulates appetite. The central histaminergic system is implicated in weight gain induced by atypical antipsychotics and has potential as a therapeutic target for obesity treatment.

Summary: Limited intermittent consumption of palatable food reduces stress responses in chow-fed rats, but this effect is diminished in rats with diet-induced obesity. Adult male rats were given unlimited access to high-fat, high-sugar diet or normal chow, followed by limited sucrose intake for 2 weeks. The results showed that sucrose reduced stress responses in lean rats, but not in obese rats. This suggests that obesity attenuates the stress-relieving effects of palatable foods.

Summary: This study reveals that alcohol consumption can lead to intestinal barrier injury. NOX1, a protein, plays a role in accumulating reactive oxygen species (ROS) and causing cell apoptosis in intestinal epithelial cells. Propionate, an endogenous inhibitor of HDAC2, can alleviate oxidative stress injury and reduce cell apoptosis in the intestines.

Summary: Contemporary systems categorize patients into sub-classes based on symptoms to enable targeted treatment, but overlapping symptom categories negatively impact outcomes, lacking guidance on management. An APAGE working group developed clinical practice guidelines for management of patients with functional dyspepsia (FD) who have overlaps with other functional gastrointestinal disorders. They identified putative pathophysiology and provided a management algorithm for primary and secondary care clinicians.

Summary: This study aimed to investigate the effect and underlying mechanism of action of Fut2 in colorectal cancer (CRC). The results showed that Fut2 deficiency is closely related to the development of CRC and downregulates the fucosylation of MCAM. Therefore, regulating fucosylation may be a potential therapy for CRC, especially in patients with Fut2 gene defects.

Summary: Recent studies have shown that intestinal mechanical signals can regulate mucus synthesis and secretion through Piezo1. This study aimed to investigate the molecular mechanisms by which Piezo1 on goblet cells regulates mucus barrier function through methylation modification. The results revealed that Piezo1 mediates mechanical stimulation to inhibit H3K9me3, thereby promoting mucin2 expression in goblet cells and regulating mucus barrier function.

Summary: Impaired phenylalanine metabolism and its relationship with gut microbiota in alcohol-related liver disease (ALD) were investigated. Elevated levels of phenylalanine and its metabolites were found in the intestines of alcohol-fed mice, negatively correlated with the abundance of Lactobacillus. Phenylalanine levels were correlated with colon inflammation and intestinal barrier dysfunction, while oral supplementation of L. acidophilus improved phenylalanine metabolism and protected mice from ALD.

Summary: FMT, a treatment method for UC targeting gut microbiota, has shown varying effectiveness in clinical trials. Donor selection might be a contributing factor to this variability, as a patient's response to FMT could depend on the ability of the used donor's microbiota to restore the specific gut disturbances of the patient. This study developed a donor-recipient matching model to guide donor selection for UC in FMT, based on analysis of fecal bacterial diversity and composition.

Summary: In order to promote ecological sustainability, researchers are increasingly interested in the issue of sulphur dioxide emissions. However, current research mainly focuses on the relationship between sulphur dioxide (SO2) emissions, foreign direct investment (FDI), and trade, and the effects of trade on SO2 emissions, without giving sufficient consideration to the impact of the institutional environment and economic growth on SO2 emissions. This paper empirically tests the institutional environment and economic growth of sulphur dioxide (SO2) emissions using provincial panel data from 2008 to 2017, employing a fixed effects model. The results indicate an inverted U-shaped relationship between GDP growth and SO2 emissions. The institutional environment and higher government intervention in the region lead to a significant decrease in SO2 emissions, and the institutional environment and level of government intervention have a negative regulatory role on economic growth and SO2 emissions. The paper provides empirical evidence based on environmental governance research, particularly in the context of regional environmental governance and government environmental performance audit policy, thus promoting sustainable ecological and environmental development.

Summary: The repair of intestinal epithelial after injury is coordinated by intestinal stem cells (ISCs), which can be influenced by fucosylation catalyzed by FUT2. This study explores the role of FUT2 in ISCs using a DSS and LPS model, and demonstrates that fucosylation of ISCs alleviates epithelial damage and maintains their function and stemness. Furthermore, FUT2 depletion in ISCs aggravates epithelial damage and disrupts the growth and proliferation capacity of ISCs by inducing ER stress and the unfolded protein response. The study also identifies HYOU1 as a fucosylated protein that facilitates ISC survival and self-renewal, and improves their resistance to ER stress and inflammatory injury.

Summary: The average age of first primary colorectal cancer (CRC) diagnosis in the USA has decreased significantly from 1992 to 2017, with a more pronounced decline after 2000. Proximal CRC cases have a higher age at diagnosis compared to distal CRC cases. Advanced stage CRC patients have a lower age at diagnosis than early stage patients.
