The study's aim was to examine the serum levels of ZAG and zinc (Zn) and the Zn/ZAG in a population of children with overweight (OW) and obesity (OB), and their relationship with biochemical parameters. Our study was a cross-sectional analysis of a group of Mexican children aged 6-10 (n = 72). We analyzed anthropometric data and biochemical parameters, including fasting plasma glucose (FPG), high-density lipoprotein cholesterol (HDLc), low-density lipoprotein cholesterol (LDLc), triglycerides (TG), total cholesterol (TC), insulin, and homeostatic model assessment insulin resistance (HOMA-IR). ZAG protein levels were measured using enzyme-linked immunosorbent assay (ELISA), and serum zinc (Zn) levels were quantified using inductively coupled plasma mass spectrometry (ICP-MS). The Zn values indicate a statistically significant difference between normal weight (NW) and OW/OB children with Zn concentrations were 91 µg/dL for NW and 66 µg/dL for OW/OB children. ZAG values did not show significant differences between NW and OW/OB, and values were 2.1 mg/dL and 2.3 mg/dL, respectively. The Zn/ZAG ratio was lower in the OW/OB compared to the NW (p = 0.05). Correlations were found between FPG and Zn (p = 0.004) in NW boys, and ZAG (p = 0.046) in OW/OB boys, as well as a negative correlation between insulin and Zn in NW children of both sexes. HOMA-IR shows correlations between Zn (p = 0.008) in OW/OB boys, and ZAG (p = 0.010) in the OW/OB girls. Additionally, correlations were observed between LDLc, TG, and BMIz with Zn and ZAG in the boys. In the same way, we also found that girls with OW/OB had a Zn/ZAG ratio of - 2.32 (p = 0.043) compared to NW boys. In conclusion, our findings highlight the significant roles of Zn and ZAG in glucose and lipid metabolism. Furthermore, Zn/ZAG ratio may provide insights into nutritional deficiencies, adiposity, and metabolic health.

Immunity is compromised in beef cattle during the periparturient period. This study aims to determine the best time during pregnancy to supplement beef cows with Se-yeast to optimize humoral immunity at parturition. Multiparous, black Angus and Angus cross cows (n = 79) were used in the study. All cows had ad libitum access to a mineral supplement containing 120 mg/kg Se (US FDA regulations) from Na selenite. In addition, all cows except controls (CTR) received Se supplementation of 105 mg Se/week from Se-yeast boluses administered once weekly during their specific treatment trimester of gestation (TR1, TR2, or TR3) for 13 weeks. This dosage was supranutritional equaling 5 × the upper range of US FDA Se administration regulations. Blood was collected at parturition from all cows. Laboratory analyses studied to assess humoral immunity included measuring IBR, BVD types 1 and 2, PI3, and BRSV serum neutralization titers post vaccination, assessing total IgM and antigen-specific IgM concentrations, and determining complement-mediated bacterial killing percentages. Statistical analyses were performed using GraphPad Prism and SAS 9.4. Supranutritional Se-yeast supplementation increased whole-blood (WB) Se concentrations regardless of trimester of supplementation (all P < 0.0001). Supplementation during TR2 and TR3 was more effective in increasing WB-Se concentrations at parturition than during TR1 or CTR (all P < 0.0001). TR2 cows had higher serum neutralization titers for BRSV compared with CRT cows (P = 0.03). Total serum IgM and Vibrio coralliilyticus-specific IgM concentrations were highly correlated (r = 0.78; P < 0.0001). Compared with CTR cows, TR1, TR2, and TR3 cows had similar total IgM concentrations (all P ≥ 0.19) and similar Vibrio coralliilyticus-specific IgM concentrations (all P ≥ 0.47). Complement-mediated bacterial killing percentages were greater in TR2 and TR3 cows (> 99.6%) compared with TR1 (93.9%) and CTR (89.3%) cows, and all Se-supplemented TR groups were greater than CTR cows (all P ≤ 0.05). The significant group differences in the complement-mediated bacterial killing assay reflected WB-Se concentrations. Supranutritional Se-yeast supplementation during TR2 and TR3 is associated with higher serum neutralization titers for some viral antigens, as well as enhanced complement-mediated bacterial killing in cows at parturition. These findings suggest that Se supplementation during later trimesters of pregnancy may help combat infectious disease challenges during the periparturient period in beef cattle.</p>","PeriodicalId":8917,"journal":{"name":"Biological Trace Element Research","volume":" ","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142862953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants (N = 320) were children aged 10-14 years (mean 11.8 years) from eastern Slovakia, at an early stage of adolescence characterized by growth acceleration.

Chronic proinflammatory responses are thought to play a central role in arsenic-induced neurotoxicity. Astrocytes, which are the predominant glial cells in the central nervous system (CNS), release significant amounts of proinflammatory cytokines upon overactivation. However, the molecular mechanisms driving this response remain to be elucidated. This study aimed to elucidate the mechanisms underlying arsenic-induced astrocyte activation and the subsequent neuronal damage, both in vivo and in vitro. In a rat model of arsenic exposure, significant neuropathological damage was detected in the CA3 region of the hippocampus. Specifically, markers of astrocyte activation, such as glial fibrillary acidic protein (GFAP) and inducible nitric oxide synthase (iNOS), as well as the inflammatory cytokine interleukin (IL)-1β, were significantly upregulated, and apoptosis was markedly increased, indicating neurotoxic damage. Furthermore, in vitro experiments revealed that arsenic exposure induced substantial upregulation of cyclic GMP-AMP synthase (cGAS), stimulator of interferon genes (STING), GFAP, iNOS, and IL-1β in astrocytes, accompanied by an increase in IL-1β secretion into the culture supernatant. In addition, co-culturing neurons with conditioned medium from arsenic-exposed astrocytes resulted in significant neuronal apoptosis. Importantly, the cGAS-STING pathway inhibitor H-151 effectively suppressed the arsenic-induced astrocyte activation and IL-1β secretion, while also reducing neuronal apoptosis in the conditioned medium. Collectively, these results indicate that arsenic exposure activates the cGAS-STING signaling pathway in astrocytes, enhancing proinflammatory activation and IL-1β expression, which in turn mediates neuronal apoptosis, representing a critical mechanism underlying arsenic-induced neurotoxicity.</p>","PeriodicalId":8917,"journal":{"name":"Biological Trace Element Research","volume":" ","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
