MicroRNAs (miRNAs) regulate the genes that have important functions in the development of cis-AKI. In the present study, GPX4 was predicted as a target of miR-214-3p. Moreover, inhibiting miR-214-3p enhanced the expressions of GPX4 and SLC7A11 while decreasing the ACSL4 expression. Furthermore, miR-214-3p down-regulation protected against TEC death and renal tubule damage both in vitro and in vivo. According to these findings, inhibiting miR-214-3p would alleviate TEC ferroptosis in cis-AKI via GPX4.The national standards for clinical ethics consultation set forth by the American Society for Bioethics and Humanities (ASBH) endorse an "ethics facilitation" approach, which characterizes the role of the ethicist as one skilled at facilitating consensus within the range of ethically acceptable options. To determine the range of ethically acceptable options, ASBH recommends the standard model of decision-making (informed consent, advance directives, surrogates, best interests), which is grounded in the values of autonomy, beneficence, nonmaleficence, and justice. H. Tristram Engelhardt Jr. has sharply criticized the standard model for presuming contentful moral claims in circumscribing the range of ethically acceptable options, which, he argues, cannot be rationally justified in a pluralistic context. Engelhardt's solution is a secular clinical ethics based on a contentless principle of permission. The first part of this article lays out Engelhardt's negative claim, that reason cannot establish contentful moral claims, and his positive claim, that secular clinical ethics ought to be based on a contentless principle of permission. The second part critiques these negative and positive claims. The purpose of this paper is to defend secular clinical ethics expertise-defined as the ability of ethicists to offer justified moral recommendations grounded in consensus positions endorsed by the American Society for Bioethics and Humanities-from the radical critiques of Engelhardt, who argues that no moral or metaphysical claims, and hence no bioethical consensus, can be rationally justified. Engelhardt's critiques have caused some to worry that secular clinical ethics is in a state of theoretical crisis; this article concludes that Engelhardt's view is an unstable basis for that worry.Curcumin (Cur), a polyphenolic compound derived from Curcuma longa L., has garnered the attention of the scientific community due to its remarkable biological properties such as its potential as a photosensitizing agent for photodynamic therapy (PDT). However, due to its low solubility in aqueous media and instability at physiological and alkaline pH, Cur has struggled to find relevant clinical application. To tackle these shortcomings, two distinct Cur-based formulations based on either complexation with methyl-β-cyclodextrin (MβCD), MβCDC-Cur, or dissolution in a choline chloride (ChCl) glycerol (Gly) deep eutectic solvent (DES), DES-Cur, were produced, physio-chemically characterized and compared regarding their potential as phototherapeutic agents for blue-light antimicrobial photodynamic therapy (aPDT) approaches. SU11274 mouse Both MβCD-Cur and DES-Cur were able to greatly enhance Cur solubility profile when compared to Cur powder. However, MβCD-Cur appears to hinder some of Cur's basal biological properties and possessed greater basal cytotoxicity towards L929 murine fibroblast cell line. Furthermore, MβCD-Cur was less photo-responsive when exposed to light which may hamper its application in blue-light aPDT approaches. In contrast, DES-Cur showed good biological properties and high photoresponsivity, displaying relevant phototoxicity against bacterial pathogens (≥ 99.9% bacterial reduction) while being better tolerated by L929 murine cells. Overall, this study found DES to be the more effective vehicle for Cur in terms of phototherapeutic potential which will serve as basis to develop novel platforms and approaches for blue-light aPDT targeting localized superficial infections.Arsenic is a common environmental pollutant and poses a serious threat to human and animal health. In this study, we used the ducks to mimic arsenic trioxide (ATO) exposure and investigated the mechanism of cardiac toxicity. The results indicated that ATO inhibited the body and organ growth of ducks, led to an increase in LDH content, and caused obvious deformity, ischemia infarction. It is found that ATO exacerbated the swell of mitochondrial and the contraction of cell nuclei in the heart of ducks through transmission electron microscopy (TEM). ATO also induced an increase in MDA content; inhibited the activation of the Nrf 2 pathway; downregulated the expression of mRNA and protein of Nrf 2, HO-1, and SOD-1; and upregulated the expression of mRNA and protein of Keap 1. At the same time, ATO induced apoptosis which not only upregulated the expression levels of mRNA and proteins (Caspase 3, Cyt-C, P53, Bax) but also decreased the mRNA and protein expression level of Bcl-2. These results indicated that ATO can lead to oxidative stress and apoptosis in the heart of ducks. In general, our research shows that ATO triggers mitochondrial dysfunction, oxidative stress, and apoptosis via Nrf 2/Caspase 3 signaling pathway in the heart of ducks.
Biologic therapies are effective at inducing and maintaining remission in people with inflammatory bowel disease (IBD). Previous studies have associated TNF-a inhibitors with weight gain, however, it is unclear if this is a class-specific effect or a manifestation of good disease control. To clarify this issue, a retrospective study was undertaken to examine weight changes over time during therapy with different biologic agents.

Adult patients with IBD who received any biological therapy for at least 12months, between 2008 and 2020, were identified at two specialised IBD services. Demographic, disease, and therapy-related data were examined. Weight change and patterns thereof were examined for each specific therapy and relationships amongst weight outcomes and various predictive factors explored.

Of 294 patients (156 females), 165 received Infliximab (IFX), 68 Adalimumab (ADA), 36 Vedolizumab (VDZ) and 25 Ustekinumab (UST). There was a statistically significant weight gain over time in the IFX and VDZ groups and more weight gain in the IFX vs ADA and VDZ vs ADA at most time points. Three weight trajectories were identified around 95% of patients had small weight loss or a modest weight gain but 5% of patients, most of whom were on IFX had marked weight gain (24.3kg). Having a baseline high BMI, being female, having an initiation CRP ≤ 5 or albumin > 35 reduced the odds of major weight gain.

Weight gain in biologic treated IBD patients appears to be associated with clinical factors (male gender, high CRP, low albumin) and therapy-specific factors.

In addition, glucose-dependent metabolic pathways, including substrates of the Krebs cycle, are involved in peripheral and central innate immune activation through a molecular program known as trained immunity. Notably, it seems that defective glucose metabolism favors trained immunity in the brain, leading to neuronal damage and neurodegeneration. In addition, defective glucose metabolism in the brain correlates with a positive proinflammatory profile and microglia activation, as was found in postmortem samples of neurodegenerative pathologies. We hypothesized that fluctuations in glucose supply or metabolism in the brain during aging may alter microglial training, turning these cells to unresponsive or overresponsive to a challenge during age-related neurodegeneration. This review will cover the most significant advances in glucose-dependent metabolic pathways that favor innate trained immunity of microglia and their contribution to neurodegeneration.
Lipoprotein metabolism is essential for the growth and proliferation of cancer cells, and is involved in the supply of energy and cellular components. Lipoprotein lipase (LPL) is a very important enzyme in lipoprotein metabolism; however, the details underlying the mechanism of LPL secretion are unclear. Palbociclib is an antitumor drug that inhibits cell cycle progression and suppresses the growth of cancer cells. The effects of palbociclib on energy metabolism, particularly on lipid metabolism, have not been fully elucidated.

We examined the regulation of LPL secretion, which is primarily involved in lipoprotein metabolism. FM3A mouse mammary tumor cells, which are hormone receptor-positive breast cancer cells, were treated with palbociclib, and the activity and protein levels of secreted LPL were measured. Moreover, the changes in intracellular lipid content were measured by fluorescence staining using Nile Red.

FM3A cells were treated with palbociclib, the activity and protein content of secreted LPL were increased. The stimulatory secretion of LPL by palbociclib was suppressed by an intracellular Ca
chelator (BAPTA-AM) and a Ca
/calmodulin-dependent protein kinase kinase (CaMKK) inhibitor (STO-609). Furthermore, the palbociclib-stimulated secretion of LPL was not observed in AMP-activated protein kinase (AMPK)-knockdown cells. An increase in the fluorescence intensity of Nile Red was observed in palbociclib-treated cells; however, no increase was observed in LPL-knockdown cells.

Our data suggest that palbociclib causes intracellular lipid accumulation in breast cancer cells by stimulating Ca
/CaMKK/AMPK-mediated LPL secretion.

MSCs from diabetic rats (dBM-MSC) have shown a tendency to differentiate towards adipocytes (AD) instead of osteoblasts (OB). Since photobiomodulation (PBM) therapy is a non-invasive treatment capable of recovering the osteogenic potential of dBM-MSCs, we aimed to evaluate whether PBM can modulate MSC's differentiation under hyperglycemic conditions. BM-MSCs of healthy and diabetic rats were isolated and differentiated into osteoblasts (OB and dOB) and adipocytes (AD and dAD). dOB and dAD were treated with PBM every 3 days (660 nm; 5 J/cm2; 0.14 J; 20 mW; 0.714 W/cm2) for 17 days. Cell morphology and viability were evaluated, and cell differentiation was confirmed by gene expression (RT-PCR) of bone (Runx2, Alp, and Opn) and adipocyte markers (Pparγ, C/Ebpα, and C/Ebpβ), production of extracellular mineralized matrix (Alizarin Red), and lipid accumulation (Oil Red). Despite no differences on cell morphology, the effect of DM on cells was confirmed by a decreased gene expression of bone markers and matrix production of dOB, and an increased expression of adipocyte and lipid accumulation of dAD, compared to heatlhy cells. On the other hand, PBM reversed the effects of dOB and dAD. The negative effect of DM on cells was confirmed, and PBM improved OB differentiation while decreasing AD differentiation, driving the fate of dBM-MSCs. These results may contribute to optimizing bone regeneration in diabetic patients.
