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...

Age-related changes in P2Y receptor signalling in mouse cochlear supporting cells
J Physiol. 2023 Sep 16. doi: 10.1113/JP284980. Online ahead of print.ABSTRACTOur sense of hearing depends on the function of a specialised class of sensory cells, the hair cells, which are found in the organ of Corti of the mammalian cochlea. The unique physiological environment in which these cells operate is maintained by a syncitium of non-sensory supporting cells, which are crucial for regulating cochlear physiology and metabolic homeostasis. Despite their importance for cochlear function, the role of these supporting cells in age-related hearing loss, the most common sensory deficit in the elderly, is poorly understoo...

Orbitofrontal cortex conveys stimulus and task information to the auditory cortex
Curr Biol. 2023 Sep 12:S0960-9822(23)01139-9. doi: 10.1016/j.cub.2023.08.059. Online ahead of print.ABSTRACTAuditory cortical neurons modify their response profiles in response to numerous external factors. During task performance, changes in primary auditory cortex (A1) responses are thought to be driven by top-down inputs from the orbitofrontal cortex (OFC), which may lead to response modification on a trial-by-trial basis. While OFC neurons respond to auditory stimuli and project to A1, the function of OFC projections to A1 during auditory tasks is unknown. Here, we observed the activity of putative OFC terminals in A1 ...

Damage mechanism of calcium peroxide on Microcystis aeruginosa PCC7806 and its potential application
Ecotoxicol Environ Saf. 2023 Sep 13;264:115466. doi: 10.1016/j.ecoenv.2023.115466. Online ahead of print.ABSTRACTCalcium peroxide (CP) is an oxidizing agent that can gradually release hydrogen peroxide (HP) to achieve selective killing of cyanobacteria in water blooms, and reduce the phosphorus content in the water column. Despite the potential of CP for use in cyanobacterial water bloom disposal, there is a lack of research on the mechanism of oxidative damage on cyanobacterial cells by calcium peroxide. Further studies are required to comprehend the underlying scientific principles and potential risks and benefits of app...

Calcium signals and potential therapy targets in ovarian cancer (Review)
Int J Oncol. 2023 Nov;63(5):125. doi: 10.3892/ijo.2023.5573. Epub 2023 Sep 15.ABSTRACTOvarian cancer (OC) is a deadly disease. The poor prognosis and high lethality of OC are attributed to its high degrees of aggressiveness, resistance to chemotherapy and recurrence rates. Calcium ion (Ca2+) signaling has received attention in recent years, as it appears to form an essential part of various aspects of cancer pathophysiology and is a potential therapeutic target for OC treatment. Disruption of normal Ca2+ signaling pathways can induce changes in cell cycle progression, apoptosis, proliferation and migration and invasion, le...

Pantoprazole-Induced Bone Loss through Gastrin Secretion: A Stereological Study
CONCLUSION: Overall findings revealed that pantoprazole caused bone loss, which could be prevented by adding octreotide. Because these detrimental effects were not detected in rats given both Oct and Pan, it was suggested that the effect of Pan on bone was produced by a hypergastrinemic condition.PMID:37711876 | PMC:PMC10499535 | DOI:10.1155/2023/2594664

Environ Sci Pollut Res Int. 2023 Sep 15. doi: 10.1007/s11356-023-29606-2. Online ahead of print.ABSTRACTThe Loktak Lake, a Ramsar site in Northeast India, is known for its rich biodiversity that includes a variety of macrophyte species, most of which have not been studied for their phytoremediation capacities and potential toxicity via consumption of the edible species. Therefore, a comprehensive assessment was conducted to evaluate the accumulation of selected heavy metals and nutrients in 10 dominant macrophyte species growing in Loktak Lake and to assess the potential health risks associated with consumption of the edib...

Exosomes and their miRNA/protein profile in keratoconus-derived corneal stromal cells
Exp Eye Res. 2023 Sep 13:109642. doi: 10.1016/j.exer.2023.109642. Online ahead of print.ABSTRACTKeratoconus (KC) is a corneal thinning disorder and a leading cause of corneal transplantation worldwide. Exosomes are small, secreted extracellular vesicles (30-150 nm) that mediate cellular communication via their proteins, lipids, and nucleic acid content. We aimed to characterize the exosomes secreted by primary corneal fibroblasts from subjects with or without KC. Using human keratoconus stromal fibroblast cells (HKC, n = 4) and healthy stromal fibroblasts (HCF, n = 4), we collected and isolated exosomes using serial ultrac...
