Summary: Evidence shows that long-term ambient PM exposure disrupts the hepatic core circadian clock rhythm and disturbs glucose metabolism. The expression of BMAL1, Clock, and SIRT1 is significantly affected by ambient PM. However, this disruption can be restored by RES supplementation to improve glucose metabolism disorder.

Summary: The study found that the SIRT1 activator resveratrol can prevent vascular oxidative stress and endothelial dysfunction. However, its clinical use is limited due to low oral bioavailability. A computational protocol was used to identify promising derivatives from a chemical library, and the most effective derivative, compound 3d, exhibited good antioxidant effects in human umbilical vein endothelial cells.

Summary: Sirtuins, a group of NAD(+) dependent histone deacetylases, play a crucial role in neuroprotection and cellular senescence. They regulate crucial proteins and can be targeted for therapeutic purposes in metabolic disorders. Their modulation shows promise in treating neurodegenerative diseases associated with aging and protein homeostasis.

Summary: Resveratrol, a polyphenol chemical found in many plant-based dietary products, has potential health benefits. After ingestion, it undergoes extensive metabolism, inhibits adipogenesis and fat accumulation, possesses anti-inflammatory effects, and may improve insulin sensitivity and inflammatory status. However, optimal dosage and benefits within the general population need further research.

Summary: This study investigated the effects of long-term intake of a typical sugar-sweetened soft drink on taste function. The results showed that when combined with a Western diet, the consumption of the soft drink led to a reduction in taste sensitivity in mice, which may contribute to overeating and taste dysfunction.

Summary: This study identified 34 key tastants in soy sauce, including 14 newly discovered peptides that enhance umami, kokumi, and salt tastes. The research highlights the importance of fermentation in taste formation and suggests the use of specific microorganisms to tailor the taste profile of soy sauces, particularly the salt taste sensation.

Summary: The palatability of pharmaceutical preparations is a major challenge in developing patient-friendly dosage forms. In this study, a fluorescence-based assay using human gastric parietal cells was developed to identify bitter tasting and bitter-taste modulating pharmaceutical compounds. The assay was optimized for sensitivity and used to screen flavonoids as potential bitter-masking compounds for guaifenesin. Eriodictyol, hesperitin, and phyllodulcin were found to be the most effective candidates for bitter-masking activity.

Summary: The study found that restrictive dietary approaches, including intermittent fasting, fasting-mimicking diet, and ketogenic diet, have similar effects on the gut, especially between caloric restriction, intermittent fasting, and fasting-mimicking diet. The ketogenic diet differs from other diets in terms of the occurrence of a 50 kDa truncated form of occludin, composition of the microbiota, and bile acids.

Summary: This study reports a novel compound, S9-A13, that has potent and specific inhibition on SLC26A9. Although S9-A13 has minimal effects on ion transport in human airway epithelia and mouse trachea, it induces acidification of airway surface liquid, suggesting a role of SLC26A9 in airway bicarbonate secretion.

Summary: This study aimed to investigate whether non-bitter casein is degraded into bitter peptides that stimulate gastric acid secretion. An in vitro model of gastric digestion and casein-fed pig experiments confirmed this process, while sensory analyses and in vitro screening validated the bitterness of the peptides. Functional involvement of TAS2R16 and TAS2R38 gene expression with the peptides was confirmed in HGT-1 cells. These findings are important for understanding protein digestion and its application in dietary context.

Summary: This study demonstrates the functional role of extracellular vesicles and particles (EVPs) in regulating gastric acid secretion. Pharmacological inhibition of EVPs reduces histamine-induced proton secretion, and isolated EVPs derived from HGT-1 cells show a dose-dependent modulatory effect on proton secretion. These findings suggest that EVPs could be a previously undiscovered mechanism in the regulation of gastric acid secretion.

Summary: Human gingival fibroblast cells (HGF-1 cells) are an important cell model for studying the response of gingiva to inflammatory stimuli. Recently, it was found that trans-resveratrol can repress the release of interleukin-6 (IL-6), a pro-inflammatory cytokine, in HGF-1 cells stimulated by Porphyromonas gingivalis (Pg-LPS), through the involvement of TAS2R50 bitter taste sensing receptor. This study aims to investigate the association between a compound's bitter taste threshold and its repressing effect on Pg-LPS evoked IL-6 release by HGF-1 cells.

Summary: Red meat can induce IgE-mediated allergic reactions, but the molecules responsible for these reactions are not well-known. In this study, two IgE-reactive proteins, MYL1 and MYL3, were identified as heat-stable bovine meat allergens. These proteins showed remarkable thermal stability and were able to cross intestinal epithelial cells without disturbing the integrity of tight junctions.

Summary: Heart diseases are the leading cause of death worldwide. Ketogenic diets have been used to treat epilepsy, diabetes, and obesity, which are common comorbidities of heart diseases. However, recent reports have linked ketogenic diets based on long-chain triglycerides (LCTs) to cardiac fibrosis and a reduction of heart function in rodents. The effects of LCT and LCT/MCT mix ketogenic diets on cardiac tissue integrity and the plasma metabolome were assessed in mice.
