Oxidized galectin-1 in SLE fails to bind the inhibitory receptor VSTM1 and increases reactive oxygen species levels in neutrophils
Cell Mol Immunol. 2023 Sep 22. doi: 10.1038/s41423-023-01084-z. Online ahead of print.ABSTRACTInhibitory immune receptors set thresholds for immune cell activation, and their deficiency predisposes a person to autoimmune responses. However, the agonists of inhibitory immune receptors remain largely unknown, representing untapped sources of treatments for autoimmune diseases. Here, we show that V-set and transmembrane domain-containing 1 (VSTM1) is an inhibitory receptor and that its binding by the competent ligand soluble galectin-1 (Gal1) is essential for maintaining neutrophil viability mediated by downregulated reactive...

Molecules, Vol. 28, Pages 6767: Antioxidant Properties and Secondary Metabolites Profile of Hyptis colombiana at Various Phenological Stages
In this study, H. colombiana plants at different phenological stages (vegetative, flowering, and post-flowering) were harvested to obtain essential oils (EOs) and extracts (from fresh plant materials or post-distillation waste) whose chemical compositions and antioxidant activities were determined. H. colombiana EOs distilled by microwave-assisted hydrodistillation were analyzed by GC/MS/FID, and hydroalcoholic extracts obtained from fresh plant materials or post-distillation waste were analyzed by UHPLC-ESI+/−-Orbitrap-MS. The antioxidant activity was evaluated by the ABTS+• and ORAC assays. The...

Peroxiredoxins in erythrocytes: far beyond the antioxidant role
J Mol Med (Berl). 2023 Sep 20. doi: 10.1007/s00109-023-02368-7. Online ahead of print.ABSTRACTThe red blood cells (RBCs) are essential to transport oxygen (O2) and nutrients throughout the human body. Changes in the structure or functioning of the erythrocytes can lead to several deficiencies, such as hemolytic anemias, in which an increase in reactive oxidative species generation is involved in the pathophysiological process, playing a significant role in the severity of several clinical manifestations. There are important lines of defense against the damage caused by oxidizing molecules. Among the antioxidant molecules, ...

Comprehensive profiling of the metabolome in corn silage inoculated with or without < em > Lactiplantibacillus plantarum < /em > using different untargeted metabolomics analyses
Arch Anim Nutr. 2023 Sep 19:1-19. doi: 10.1080/1745039X.2023.2247824. Online ahead of print.ABSTRACTSilage fermentation is a complicated biochemical process involving interactions between microbes and metabolites. However, the overall metabolome feature of ensiled forage and its response to lactic acid bacteria inoculation is poorly understood. Hence, in this study metabolome profiles of whole-plant corn silage inoculated with or without Lactiplantibacillus plantarum were characterised via solid-phase microextraction/gas chromatography/mass spectrometry (SPME-GC-MS), gas chromatography/time-of-flight mass spectrometry (GC-...

Mineral elements and adiposity-related consequences in adolescents with intellectual disabilities
CONCLUSION: The intellectual disability of moderate type (MID) was associated with abnormal changes in the levels of essential mineral elements and adipokines and increased levels of cellular oxidative stress. Thus, evaluating plasma mineral elements and adipokines levels could be a potential diagnostic parameter for diagnosing MID.PMID:37730529 | PMC:PMC10512604 | DOI:10.1186/s12860-023-00490-5

Fe-NPs and Zn-NPs: Advancing Aquaculture Performance Through Nanotechnology
Biol Trace Elem Res. 2023 Sep 18. doi: 10.1007/s12011-023-03850-6. Online ahead of print.ABSTRACTAquaculture is a growing industry facing several challenges, including disease control, water quality management, and sustainable feed production. One potential solution to these challenges is the use of trace elements such as iron (Fe) and zinc (Zn), either in their conventional form or as nanoparticles (NPs). Aquatic animals need these micronutrients for normal growth, physiological processes, and overall health. In marine species, iron boosts development, immunity, and disease resistance. At the same time, zinc enhances meta...

Molecules, Vol. 28, Pages 6669: Sustainable Recovery of Phenolic Compounds from Distilled Rosemary By-Product Using Green Extraction Methods: Optimization, Comparison, and Antioxidant Activity
hatzopoulou Rosemary solid distillation waste (SWR), a by-product of the essential oil industry, represents an important source of phenolic antioxidants. Green technologies such as ultrasound-assisted extraction (UAE), microwave-assisted extraction (MAE), and accelerated solvent extraction (ASE) of phenolic compounds from SWR were optimized as valorization routes to maximize yield, rosmarinic acid (RMA), carnosol (CARO) and carnosic acid (CARA) contents. Response surface methodology was used in this context, with ethanol concentration (X1), extraction temperature (X2), and time (X3) being the independent variables. A s...
