C2C12 myoblasts were transfected with siIL-10. Histological analysis, reverse transcription-quantitative polymerase chain reaction, and immunoblotting were performed on the quadriceps and tibialis anterior muscles. A publicly available dataset was analyzed to assess the Notch pathway in older men. In summary, IL-10 knockdown in myoblasts reduced the Notch pathway gene and protein expression. In SAMP8 mice, combined exercise improved muscle fiber organization, enhanced balance and coordination, and increased Notch2 and Hes1 mRNA levels. NOTCH2 mRNA levels were also higher in older men compared to young subjects with similar physical activity levels. These findings suggest that combined physical exercise enhances muscle regeneration via the Notch pathway in aged muscle.","PeriodicalId":19954,"journal":{"name":"Pflugers Archiv : European journal of physiology","volume":" ","pages":"393-405"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142971896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The respective roles of THBPs in supplying THs for tissue uptake are not completely understood. To investigate this, we developed a spatial human physiologically based kinetic (PBK) model of THs, which produces several novel findings. (1) Contrary to postulations that TTR and/or ALB are the major local T4 contributors, the three THBPs may unload comparable amounts of T4 in Liver, a rapidly perfused organ; however, their contributions in slowly perfused tissues follow the order of abundances of T4TBG, T4TTR, and T4ALB. The T3 amounts unloaded from or loaded onto THBPs in a tissue acting as a T3 sink or source respectively follow the order of abundance of T3TBG, T3ALB, and T3TTR regardless of perfusion rate. (2) Any THBP alone is sufficient to maintain spatially uniform TH tissue distributions. (3) The TH amounts unloaded by each THBP species are spatially dependent and nonlinear in a tissue, with ALB being the dominant contributor near the arterial end but conceding to TBG near the venous end. (4) Spatial gradients of TH transporters and metabolic enzymes may modulate these contributions, producing spatially invariant or heterogeneous TH tissue concentrations depending on whether the blood-tissue TH exchange operates in near-equilibrium mode. In summary, our modeling provides novel insights into the differential roles of THBPs in local TH tissue distribution.","PeriodicalId":19954,"journal":{"name":"Pflugers Archiv : European journal of physiology","volume":" ","pages":"453-478"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142922508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First commercial offers with recommendations for diet and lifestyle changes, usually based on a few polymorphisms, entered markets soon after the presentation of the human genome blueprint. Although PN has seen many attempts, meanwhile, with the inclusion of other biomedical measures such as microbiome and/or continuous glucose monitoring, scientific assessments of such approaches in various settings revealed limited success. Although personalisation improved general compliance over generic advice, particular benefits in referring to biomedical measures and individual risks did, in most cases, not provide any significant advantage. Moreover, scholars criticised such approaches as of limited impact from a public health perspective by attracting mainly technology-open individuals of high social status and proper financial capabilities. Based on these experiences, new avenues for personalising dietary advice are developed, and those are going beyond pure biomedical data by assessing the entire food environment of the individual with its capabilities and constraints in the given life setting. Embedded into digital environments for data collection but also for bidirectional communication, new possibilities emerge. Artificial intelligence methods allow for the multitude of input data and highly complex decision trees to be derived to customize advice. And that can be delivered on the spot and in time in any language whenever decisions are made on what to buy or what to eat.

Endocytosis then recovers the synaptic vesicle pool and presynaptic membrane area. The kinetics of endocytosis may shape neuromuscular transmission, determining its long-term reliability. Here, using fluorescent dyes, the time course of endocytosis induced by intense activity of the phrenic nerve was studied at the mouse diaphragm neuromuscular junction. It was found that a significant portion of endocytic events occurs after the end of tetanic stimulation. Pitstop 2, clathrin inhibitor, and more profoundly dynole 34-2, dynamin antagonist, suppressed endocytic FM1-43 dye uptake both during and after tetanus. Furthermore, synaptic vesicles formed in the presence of the endocytic blockers released FM-dye during subsequent evoked exocytosis at a lower rate. 25-Hydroxycholesterol (25HC) is an oxysterol, ubiquitously synthetized from excessive cholesterol. In addition, its production greatly increases by activated macrophages. 25HC accelerated FM-dye endocytosis and its sequential evoked exocytosis, and dynole (but not pitstop) prevented 25HC-mediated enhancement of endocytic FM-dye uptake. The positive effects of 25HC were interfered with chelation of cytosolic Ca2+ with a slow Ca2+ buffer EGTA-AM, Ca2+ antagonist TMB8, and sphingomyelin-hydrolyzing enzyme. In contrast to amphiphilic FM1-43 dye capture, 25HC reduced uptake of hydrophilic high molecular weight markers (labeled dextrans and toxin), which utilize bulk endocytosis to enter into nerve terminals. Thus, synaptic vesicle endocytosis had a relatively slow kinetics following the tetanic activity and can be accelerated by 25HC. The positive effect of 25HC on endocytosis engages a dynamin-dependent pathway, interconnected with cytoplasmic Ca2+ and sphingomyelin integrity.","PeriodicalId":19954,"journal":{"name":"Pflugers Archiv : European journal of physiology","volume":" ","pages":"421-439"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142953139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rodent studies provided evidence for these regulatory loops, while controlled experiments in healthy humans examined periods of either a few hours or several weeks, and often varied dietary calcium intake. The effects of controlled, isolated changes in dietary Pi intake over shorter periods are unknown. We studied the effects of a low or high Pi diet on parameters of mineral metabolism in 10 healthy young men. Participants received a standardized diet (1000 mg phosphorus equivalent/day) supplemented with either a phosphate binder (low Pi diet) or phosphate capsules (750 mg phosphorus, high Pi diet) in a randomized cross-over trial for 5 days with a 7-day washout between diets. High Pi intake increased plasma Pi levels and 24-h excretion and decreased urinary calcium excretion. High Pi intake increased intact FGF23 (iFGF23) and suppressed plasma Klotho without affecting cFGF23, PTH, calcidiol, calcitriol, Fetuin-A, dopamine, epinephrine, norepinephrine, metanephrine, or aldosterone. Higher iFGF23 correlated with lower calcitriol and higher PTH. These data support a role for iFGF23 in increasing renal Pi excretion and reducing calcitriol in healthy young men during steady-state high dietary Pi intake. High dietary Pi intake elevated blood Pi levels in healthy young subjects with normal renal function and may therefore be a health risk, as higher serum Pi levels are associated with cardiovascular risk in the general population.","PeriodicalId":19954,"journal":{"name":"Pflugers Archiv : European journal of physiology","volume":" ","pages":"495-508"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11825603/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142731753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lateral habenula (LHb) is noted to be involved in stress-induced behavioral responses. However, its involvement in stress-induced respiratory responses is unknown. In this study, we aimed to analyze whether and how the LHb regulates respiration. Electrical stimulation of the LHb of anesthetized Wistar male rats increased respiratory frequency and minute ventilation, calculated by respiratory frequency × thoracic movement amplitude. Systemic administration of a dopaminergic receptor antagonist, clozapine, suppressed the LHb-induced respiratory responses. On the other hand, administration of a serotonergic receptor antagonist, methysergide, significantly accelerated the LHb-induced increase in respiratory frequency, together with suppressing the thoracic movement amplitude. To clarify the source of dopaminergic modulation, we inhibited the ventral tegmental area (VTA), which contains dopaminergic neurons and receives inputs from the LHb, by administering microinjections of a GABAA agonist, muscimol. The bilateral inhibition of the VTA almost abolished the LHb-induced respiratory responses. These results suggest that LHb activation causes respiration acceleration, mainly mediated by dopaminergic neurons in the VTA and suppressively modulated by the serotonergic system. Neural circuits originating in the LHb may be a key modulator for respiration during psychological stress.","PeriodicalId":19954,"journal":{"name":"Pflugers Archiv : European journal of physiology","volume":" ","pages":"441-452"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11825555/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142668573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
