The emerging functions of mini zinc finger (MIF) microproteins in seed plants: A minireview
Biochimie. 2023 Sep 16:S0300-9084(23)00243-2. doi: 10.1016/j.biochi.2023.09.016. Online ahead of print.ABSTRACTMini zinc fingers constitute a class of microproteins that appeared early in evolution and expanded in seeds plants. In this review, the phylogenetic history, the functions and the mode of action of MIFs in plants are reported and discussed. It appears that mini zinc finger microproteins play an important role in the control of plant development. They are involved in the control of cell division and expansion and in the switch between the determinate/indeterminate state of the meristems. They are involved in the r...

Application of lipid and polymeric-based nanoparticles for treatment of inner ear infections via XGBoost
Environ Res. 2023 Sep 15:117115. doi: 10.1016/j.envres.2023.117115. Online ahead of print.ABSTRACTTaking hearing loss as a prevalent sensory disorder, the restricted permeability of blood flow and the blood-labyrinth barrier in the inner ear pose significant challenges to transporting drugs to the inner ear tissues. The current options for hear loss consist of cochlear surgery, medication, and hearing devices. There are some restrictions to the conventional drug delivery methods to treat inner ear illnesses, however, different smart nanoparticles, including inorganic-based nanoparticles, have been presented to regulate dru...

Environ Res. 2023 Sep 15:117122. doi: 10.1016/j.envres.2023.117122. Online ahead of print.ABSTRACTWe have synthesized an n-p-n heterojunction of carbon nitride (C3N4), zinc oxide (ZnO), and black phosphorus (BP) through the sonication-stirring method. The photocatalytic ability of this composite was examined for the decomposition rhodamine B (RhB) and detoxification of hexavalent chromium ion (up to 97% during 80 min) under Xenon irradiation. The results of trapper experiments indicated that the active species were hydroxyl radical (˙OH), electron (e-), and superoxide anion radical (˙O2-). Based on the obtained potential...

Green synthesis of multifunctional zinc oxide nanoparticles from cordia myxa gum; and their catalytic reduction of nitrophenol, anticancer and antimicrobial activity
This study uses CMX gum as a bioreduction to produce multifunctional, environmentally friendly zinc-oxide nanocomposites (ZnO NPs). The process involves a low reaction time and temperature and utilizes CMX as a reducing and stabilizing agent. The structural, morphological, and optical properties of the CMX-ZnO nanocomposite were characterized. The biosynthetic CMX-ZnO NPs exhibited robust catalytic activity and recycling capacity for rapidly oxidizing hazardous p-NPs. The complete reduction of 4-NP to CMX-ZnO NPs in excess NaBH4 was achieved within 15 min, with recyclability and pseudo-first-order kinetics with a rate cons...

Chronic memantine disrupts spatial memory and up-regulates Htr1a gene expression in the hippocampus of GPR39 (zinc-sensing receptor) KO male mice
We report: no effects of acute memantine on ELM; a tendency to improve the "where?" component of ELM in both WT and GPR39 KO mice following 12 days of memantine; and, a disruption of SM in GPR39KO mice after 24 days of memantine treatment. The latter result was associated with upregulation of Htr1a hippocampal expression.PMID:37716463 | DOI:10.1016/j.brainres.2023.148577

Regulatory effect of zinc finger protein A20 on rheumatoid arthritis through NLRP3/Caspase-1 signaling axis mediating pyroptosis of HFLS- RA cells
In conclusion, this study is of great significance for understanding the role of the NLRP3-caspase-1-IL-1β/ pyroptosis signaling pathway in the occurrence and development of RA. It is expected that the results will provide a theoretical basis for the immune regulation of innate immunity in the occurrence and development of RA, while providing a new therapeutic target for the clinical treatment of RA.PMID:37715399 | DOI:10.14715/cmb/2023.69.8.27

Multi-element Exposure and Cognitive Function in Rural Elderly Chinese
Biol Trace Elem Res. 2023 Sep 16. doi: 10.1007/s12011-023-03774-1. Online ahead of print.ABSTRACTTo investigate the relationship between selenium (Se) based multi-element combined exposure and cognitive function in rural elderly individuals, a cross-sectional study was conducted. The study involved 416 older adults aged 60 and above, residing in four different areas of Enshi county, China, with varying soil Se levels. Inductively coupled plasma mass spectrometry (ICP-MS) was employed to measure the concentrations of Se, copper (Cu), iron (Fe), zinc (Zn), calcium (Ca), magnesium (Mg), cadmium (Cd), arsenic (As), and lead (P...

An Organic Coordination Manganese Complex as Cathode for High-Voltage Aqueous Zinc-metal Battery
Angew Chem Int Ed Engl. 2023 Sep 16:e202309430. doi: 10.1002/anie.202309430. Online ahead of print.ABSTRACTAqueous Zn-Mn battery has been considered as the most promising scalable energy-storage system due to its intrinsic safety and especially ultralow cost. However, the traditional Zn-Mn battery mainly using manganese oxides as cathode shows low voltage and suffers from dissolution/disproportionation of the cathode during cycling. Herein, for the first time, a high-voltage and long-cycle Zn-Mn battery based on a highly reversible organic coordination manganese complex cathode (Manganese polyacrylate, PAL-Mn) was construc...

Take a walk on the KRAB side
Trends Genet. 2023 Sep 14:S0168-9525(23)00185-3. doi: 10.1016/j.tig.2023.08.003. Online ahead of print.ABSTRACTCanonical Krüppel-associated box (KRAB)-containing zinc finger proteins (KZFPs) act as major repressors of transposable elements (TEs) via the KRAB-mediated recruitment of the heterochromatin scaffold KRAB-associated protein (KAP)1. KZFP genes emerged some 420 million years ago in the last common ancestor of coelacanth, lungfish, and tetrapods, and dramatically expanded to give rise to lineage-specific repertoires in contemporary species paralleling their TE load and turnover. However, the KRAB domain displays se...
