Summary: This study aimed to investigate the effects of fructose consumption on the adolescent brain and verify whether these alterations can be reversed after returning to a normal diet. The findings showed that a short-term fructose-rich diet induced mitochondrial dysfunction and oxidative stress, but these changes were partially recovered by switching back to a control diet.

Summary: The supplementation of stingless bee honey (SBH) and pure antioxidant caffeic acid (CA) can reverse the hyperglycemic and hypertensive effects induced by high-carbohydrate high-fructose (HCHF) diet. SBH can significantly reduce brain TNF-alpha levels and increase brain neurotrophic factor BDNF levels.

Summary: The study found that fructose intake can lead to inflammation, oxidative stress, mitochondrial dysfunction, and changes in neurotrophins and neurotransmitters in the brain. These alterations persisted even after switching to a healthy diet, highlighting the importance of limiting excessive consumption of sweet foods during adolescence.

Summary: In this study, the mitochondrial localization of a novel mitochondrial calpain, calpain-13, in the mouse brain was investigated. The presence of calpain-13 in both the mitochondrial membrane and soluble fractions was confirmed, and its expression in the cerebral cortex and hippocampus was observed. Further studies on the enzymatic properties and physiological functions of calpain-13 in both the cytosol and mitochondria will provide insights into its potential involvement in neurodegenerative diseases.

Summary: This study utilized a proteomic approach to investigate the impact of high-fructose plus high-fat diet (HFr/HFD) and high-fat diet (HFD) on liver injury in murine models. The results showed that the hepatic mitochondrial oxidative phosphorylation pathway was significantly downregulated in the HFr/HFD group compared to the HFD group, with alterations in protein levels of specific complexes within the pathway.

Summary: The short-term consumption of a high-fructose diet has a significant impact on skeletal muscle metabolism, with more pronounced effects in young individuals than in adults. The study found that young rats showed marked mitochondrial dysfunction and increased oxidative damage, leading to a decrease in insulin sensitivity. These findings highlight the importance of reducing fructose intake, especially in young people, to maintain metabolic health.

Summary: This systematic review investigated the relationship between dietary patterns in healthy middle-aged adults and neurocognition both in middle age and later in life. The findings were mixed, with some studies reporting a significant positive relationship between adherence to various healthy dietary patterns and neurocognition, but others reporting no such relationship. However, the review suggests that adherence to the Mediterranean diet and other healthy dietary patterns in middle age can protect neurocognition later in life.

Summary: This study investigated the therapeutic potential of ultramicronized palmitoylethanolamide (um-PEA) in 3 x Tg-AD mice. The results showed that um-PEA can improve the complex-I respiration rate and ATPase activity, as well as ATP content in the cortical mitochondria of the mice. However, um-PEA treatment did not improve the mitochondrial bioenergetics impairments and glutamate release in the hippocampus.

Summary: This study investigated the effects of maternal omega-3 PUFA supplementation or deficiency on the endocannabinoid system and synaptic markers in postnatal offspring. The findings suggest that variations in maternal dietary omega-3 PUFA levels may impact differently on the ECS and molecular markers in the cerebral cortex and hippocampus of the progeny.

Summary: The study found that a short-term ketogenic diet increased mitochondrial content in the red gastrocnemius muscle, but did not alter mitochondrial content in the liver, prefrontal cortex, or hippocampus. These results indicate tissue-specific changes in mitochondrial mass with a ketogenic diet.

Summary: The study aimed to evaluate the relationship between metabolic and bioenergetic changes induced by a two-hit protocol and cognitive function in mice. The results showed that the two-hit protocol, involving a high-fat diet and low doses of streptozotocin, impaired cognitive function and affected the energy metabolism in brain tissues. These findings highlight the detrimental impact of early overnutrition on cognitive function.

Summary: Maternal high-fat diet and fructose induced alterations in lipid metabolism and mitochondrial function in skeletal muscle of adult offspring. These changes were modified by maternal diet and fiber type, and were associated with higher skeletal muscle fructose-induced mitochondria injury in adult offspring.

Summary: This study found that offspring of mothers with advanced maternal age (AMA) without exercise training exhibited poor cognitive function, neuroplasticity, and mitochondrial function compared to offspring of mothers with AMA who underwent exercise training. These findings suggest that exercise contributes to a positive prenatal environment, preventing decreased cognitive function in offspring of mothers with AMA.

Summary: Increased fructose intake, especially in combination with a high-fat diet, can lead to obesity and metabolic complications. Fructose impairs the oxidation of dietary fat by affecting the mitochondrial beta-oxidation pathway and inhibiting the production of acylcarnitine. This explains the synergistic effects of fructose and fat on the development of conditions like non-alcoholic fatty liver disease.

Summary: Mitochondrial protein IF1 binds to ATP synthase and inhibits ATP hydrolysis in ischemic tissues. It is overexpressed in tumors and acts as a pro-oncogenic protein. Study found that disruption of ATP5IF1 gene decreases colony formation and tumor mass development in HeLa cells, indicating the role of IF1 in cancer. Lack of IF1 does not affect cell proliferation or mitochondrial respiration, but sensitizes cells to opening of the permeability transition pore (PTP). IF1 binds to ATP synthase OSCP subunit in HeLa cells under oxidative phosphorylation conditions, and this interaction protects cancer cells from PTP-dependent apoptosis under normoxic conditions.
