Summary: Obesity induced by high-fat diet was found to promote lung tumorigenesis in C57BL/6J mice, with leptin-mediated activation of the PI3K/Akt/mTOR/STAT3 pathway likely playing a key role in this mechanism.

Summary: This study explored the effects of a high fat diet on glucose metabolism and bone density in developing and mature male C57BL/6J mice. The results showed that high fat diet significantly impaired glucose tolerance and reduced bone density in both age groups, with more pronounced effects in the mature mice. This mature HFD mouse model accurately represents late-onset impaired glucose tolerance/pre-T2DM cases in humans and provides insights into the mechanisms of skeletal fragility in these patients.

Summary: This study found that alcohol use disorder has long-term effects on the dopamine system, including sensitization of D2 dopamine autoreceptors and a decrease in cholinergic control of dopamine release. Interestingly, some of these effects can be reversed during abstinence, suggesting that certain neuroadaptations in AUD may be reversible.

Summary: The study revealed significant differences in responses to high-fat diet between male and female mice, particularly in body weight gain, food intake, energy expenditure, and insulin sensitivity. Male mice gained weight faster, had an increase in pancreatic beta cell area, and reduced insulin sensitivity after HFD feeding, while female mice did not exhibit these phenomena.

Summary: This study investigated the potential therapeutic mechanism of Lycium barbarum oligosaccharide (LBO) against hepatic steatosis induced by high-fat diets (HFD) by analyzing the changes in intestinal flora and metabolites in mice. LBO administration significantly reduced serum triglyceride (TG), alanine aminotransferase (ALT), and hepatic TG levels in mice on an HFD, and improved liver lipid accumulation. LBO also modulated the composition of intestinal flora and fecal metabolites related to cholesterol metabolism, bile acid metabolism, and tryptophan metabolic pathways.

Summary: The study revealed that lunasin can reduce inflammation levels in obese mice, decrease macrophage infiltration in adipose tissue, and regulate spleen size and cell numbers. Additionally, lunasin promotes the production of interferon gamma and interleukin-2 in splenocytes, thus modulating immune responses.

Summary: Chronic exposure to a high-fat diet can lead to weight gain and behavioral deficits. In C57BL/6J mice, these effects begin at the 3rd month of dietary exposure and behavioral deficits occur at around 3-4 months after increased body weight.

Summary: This study found that the components VPP and IPP derived from bovine casein hydrolysates can alleviate chronic inflammation caused by obesity and improve adipocyte dysfunction. The results showed that 4% casein hydrolysates could mitigate high fat diet-induced chronic inflammation and prevent obesity-related inflammation and adipocyte dysfunction.

Summary: The study found that despite inducing cardiac hypertrophy and increasing cardiac fatty acid metabolism, long-term fat feeding in mice may not be enough to activate pathological hypertrophic mechanisms that impair cardiac function or induce cardiac fibrosis. Additionally, unknown factors may contribute to the cardiac abnormalities reported by many research groups.

Summary: MeHg disrupts the physiological functions of ghrelin differently in males and females, enhancing ghrelin-induced body weight gain in males by activating the AMPK/UCP2 signaling pathway and mitigating ghrelin-induced weight gain in females by inhibiting mTOR signaling and decreasing Npy mRNA expression.

Summary: This study investigated the anti-obesity effects of an aqueous extract of Sunbanghwalmyung-eum (SBH) in high-fat and high-cholesterol diet-induced obese mice. The results showed that SBH reduced body weight gain and fat accumulation, improved plasma lipid levels, inhibited inflammation, and regulated adipogenic factors, ultimately alleviating obesity symptoms.

Summary: This study investigated the effects of a high-protein diet and high-intensity interval training on appetite and weight loss in obese middle-aged individuals. The results showed that consuming a high-protein drink and following a high-protein diet after exercise can reduce post-exercise appetite and the frequency of late-night snacking.

Summary: There is evidence to suggest that chronic stress impacts neurochemical homeostasis and contributes to mental disorders. This study investigates the therapeutic potential of p-coumaric acid (p-CA), a natural compound found in vegetables and fruits, against stress-associated mental disorders. The findings suggest that p-CA could alleviate cognitive deficits and depression-like behavior in mice exposed to chronic restraint stress (CRS) by regulating the PKA-CREB-BDNF signaling pathway.

Summary: The present study investigated the post-operative complications and therapeutic potential of J147 in male Zucker rats, and found that J147 treatment had positive effects on behavioral and metabolic parameters, but did not affect neuroinflammation. The results suggest that a combination of acute and chronic J147 treatment may be optimal for treatment.

It was found that pleasant odors have a positive impact on participants' physical activity. However, better methodological consistency is needed in studies to produce more meaningful results.

Summary: This study examined sleep, sleep/wake regularity, and cognition in college students diagnosed with depression and using serotonergic antidepressants, comparing them to those without a depression diagnosis. The results showed that students using antidepressants had slightly longer wake after sleep onset and lower sleep efficiency, but these differences were likely not noticed by the participants. There were no differences in sleep regularity or cognition between the two groups.

Summary: Social stress plays a significant role in the development of neuropsychiatric disorders and can lead to behavioral deficits such as social withdrawal. This study investigates the impact of social stress on social reward in Syrian hamsters. The results show that subordinate and socially defeated males have reduced motivation for social interactions compared to dominant males. Additionally, winning males exhibit greater activation in the mesolimbic dopamine system compared to losers. In females, there were no differences in social entries between winners and losers, but winning females display more activation in the NAc shell.

Summary: This study examined the association between body mass index (BMI) and negative emotional states (NES) in men with substance use disorders (SUD) undergoing treatment. The findings showed a positive correlation between BMI and stress, anxiety, and depression. These results suggest that reducing body fat accumulation may contribute to improving mental health in individuals with SUD during recovery.

Summary: This PROSPERO pre-registered systematic review and meta-analysis evaluated the olfactory and gustatory changes in pregnant individuals. The meta-analysis revealed that pregnant individuals performed poorer in odour identification, rated olfactory stimuli to be more intense during the second and third trimester, and had increased pleasantness for sweet taste in the first trimester. No major difference was observed in terms of gustatory functions between pregnant and non-pregnant subjects.
