Further study in mesoderm differentiation reveals that mitochondrial dysfunction causes proliferation disability and YAP nuclear translocalization and thus together blocks mesoderm lineage differentiation. These findings provide new insights into understanding the mitochondrial function in human pluripotency maintenance and mesoderm differentiation.Hepatic lipotoxicity is a crucial factor in nonalcoholic steatohepatitis resulting from excessive saturated fatty acid-induced reactive oxygen species (ROS)-mediated cell death, which is associated with the accumulation of endoplasmic reticulum (ER) stress in the liver. The unfolded protein response (UPR) alleviates ER stress by restoring ER protein folding homeostasis. However, whether UPR contributes ROS elimination under lipotoxicity remains unclear. The Kelch like ECH-associated protein 1 (KEAP1)-nuclear factor, erythroid 2 like 2 (Nrf2) pathway provides antioxidant defense against lipotoxic stress by eliminating ROS and can be activated by the p62-Unc-51 like autophagy activating kinase 1 (ULK1) axis. However, the upstream molecular regulator of the p62-ULK1 axis-induced KEAP1-Nrf2 pathway in the same context remains unidentified. Here, we demonstrated that PKR-like ER kinase (PERK), a UPR sensor, directly phosphorylates p62 and ULK1, thereby activating the noncanonical KEAP1-Nrf2 pathway. We also elucidated the molecular mechanism underlying the PERK-mediated p62-ULK1 axis-dependent noncanonical KEAP1-Nrf2 pathway, which could represent a promising therapeutic strategy against hepatic lipotoxicity.Alpha-methyl-para-tyrosine (AMPT), a competitive inhibitor of tyrosine hydroxylase, can be used to deplete endogenous dopamine in humans. We examined how AMPT-induced dopamine depletion alters resting-state functional connectivity of the basal ganglia, and canonical resting-state networks, in healthy humans. Fourteen healthy participants (8 females; age [mean ± SD] = 27.93 ± 9.86) completed the study. Following dopamine depletion, the caudate showed reduced connectivity with the medial prefrontal cortex (mPFC) (Cohen's d = 1.89, p less then .0001). Moreover, the caudate, putamen, globus pallidus, and midbrain all showed reduced connectivity with the occipital cortex (Cohen's d = 1.48-1.90; p less then .0001-0.001). Notably, the dorsal caudate showed increased connectivity with the sensorimotor network (Cohen's d = 2.03, p=.002). AMPT significantly decreased self-reported motivation (t(13)=4.19, p=.001) and increased fatigue (t(13)=4.79, p=.0004). A greater increase in fatigue was associated with a greater reduction in connectivity between the substantia nigra and the mPFC (Cohen's d = 3.02, p less then .00001), while decreased motivation was correlated with decreased connectivity between the VTA and left sensorimotor cortex (Cohen's d = 2.03, p=.00004). These findings help us to better understand the role of dopamine in basal ganglia function and may help us better understand neuropsychiatric diseases where abnormal dopamine levels are observed.
Surgery can significantly improve the prognosis of patients with gastric cancer. However, some patients are at a later stage at diagnosis and need to receive neoadjuvant chemotherapy (NACT). Previous studies have shown that NACT may lead to more postoperative complications. Probiotics have the potential to reduce postoperative complications and infections, but no similar clinical trials have been conducted in patients with gastric cancer receiving NACT. The aim of this study was to investigate the effect of probiotics on postoperative infections and other short-term outcomes in patients with gastric cancer receiving NACT.

This was a randomized, double-blind, controlled trial. All patients who underwent minimally invasive surgery after NACT were included and randomized into a probiotic group (PG; n=33) or a control group (CG; n=33). Postoperative infectious complications, recovery of gastrointestinal function, postoperative hospital stay, medical costs, time to initiate adjuvant chemotherapy, 30-d readmissatients in the PG started adjuvant chemotherapy earlier than CG patients.
Fibroblast growth factor 23 (FGF23) controls the production and degradation of biologically active vitamin D, 1,25(OH)

, and phosphate reabsorption in the kidney as a hormone synthesized by bone cells. Additional paracrine effects in other organs exist as well. As a biomarker, the FGF23 plasma concentration increases in renal and cardiovascular diseases, and is correlated with outcome. The regulation of FGF23 is incompletely understood and dependent on several factors, including oxidative stress. L-homocysteine is an amino acid produced in methionine metabolism, and can be converted into further metabolites depending on the availability of vitamin B. learn more Hyperhomocysteinemia is a potential cardiovascular risk factor. Our study aimed to explore whether homocysteine impacts FGF23 synthesis.

Experiments were performed in UMR106 osteoblast-like cells. Fgf23 gene expression and FGF23 protein concentration were measured by quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assay, respectively. Oxidative stress was determined by 2',7'-dichlorofluorescein diacetate fluorescence.

Homocysteine dose-dependently upregulated Fgf23 gene expression and protein synthesis. Moreover, homocysteine imposed oxidative stress on UMR106 cells. The effect of homocysteine on Fgf23 was abrogated by antioxidant ascorbic acid.

Homocysteine is a potent stimulator of FGF23 production, an effect at least in part mediated by oxidative stress. The homocysteine-dependent upregulation of FGF23 presumably contributes to its role as a cardiovascular risk factor.

Not surprisingly, natural antioxidants play pivotal roles in the decreasing of these diseases by their hydrophilicity, permeability, multi-factored interactions with biological surroundings, while the antioxidative effects are dependent upon the bond energies, donors or acceptors of hydrogen bonds as well as other physical properties of the functional groups. However, in comparison with natural antioxidants the synthetic antioxidants sometimes exhibit potentially deleterious effects, viz., pro-oxidative properties, and it is thereby worth exploring the structures of natural antioxidants with the aim of achieving valuable information for the antioxidative structures. Here, more than 70 natural antioxidants are collected from recent publications, and their configurations are optimized at MM2 level for summarizing the common characteristics from their structures. It is found that all the natural phenols, flavonoids, anthraquinones, alkaloids, terpenoids, and steroids exert three-dimensional (3D) architectures rather than a merely planar conjugation system. Hence, this 3D conformation might be beneficial for the natural antioxidants being recognized by biological surroundings. This deduction has been demonstrated by some synthetic antioxidants, in which their structures have been conformed to be 3D architecture. The 3D architecture will become a direction for the designing of antioxidative structures, and the testing of antioxidative effect is encouraged to employ signaling pathways, protein targets, and cell lines rather than individual radical-scavenging evaluation.
Non-small cell lung cancer (NSCLC) accounts for approximately 85% of lung cancer, which is the deadliest form of cancer worldwide. Recent studies have shown that genes in the fibroblast growth factor (FGF) family are highly mutated in lung cancer, and fibroblast growth factor receptor 1 (FGFR1) has been found to be involved in various cancers, including lung cancer, suggesting that FGFR1 is a valid therapeutic target. Hypocrellin A (HA), a molecule with multiple biological activities, has been shown to influence cancer growth, but the specific mechanisms of its antitumor action have not been fully explored.

MTT, colony formation, wound healing, transwell cell invasion and EdU cell proliferation assays were performed upon HA treatment of three NSCLC cell lines, H460, PC-9 and H1975. Hoechst 33258 staining and caspase 3 activity assays were carried out to investigate the impact of HA on apoptosis in these cells. Molecular docking and surface plasmon resonance were conducted to assess binding of HA to FGFR1. A mouse tumor model was used to detect the NSCLC-inhibitory ability of HA in vivo.

Through in vitro assays, HA was shown to negatively impact cell viability, migration, invasion and promote apoptosis in three human NSCLC cell line models. HA was shown to bind to FGFR1 and to inhibit its autophosphorylation and the phosphorylation of downstream signaling molecules. Inhibition of tumor growth was also demonstrated in a mouse xenograft tumor model, and no toxic effects of HA treatment were observed.

HA inhibits the activity of the FGFR1 and STAT3 signaling pathways. HA thus represents a potential new FGFR1-targeted treatment for NSCLC.

However, the reduction of chlorides by washing only has limited success due to the presence of insoluble Friedel's salt (FS) in the ash. Although some studies on the decomposition of FS and the application of advanced chloride removal methods to bottom ash have been reported, few studies have compared the effects of different removal methods. Moreover, due to the complex ash composition, it is also necessary to compare the effects on different ashes and pure FS. Therefore, in this study, we applied five advanced chloride removal methods to synthesized FS and two types of bottom ash (FS-High and FS-Low), and compared the effects. For both FS and bottom ash, all methods promoted chloride dissolution more than washing only. For FS, aging was the most effective method, with a Cl removal ratio of 73%. In contrast, for ash FS-High, aging increased the Cl removal ratio to 80% and decreased the Cl content to 2800 mg/kg. The FS-derived peak observed in an X-ray diffraction analysis disappeared following aging. For ash FS-Low, acid washing increased the Cl removal ratio to 64% and decreased the Cl content to 1800 mg/kg. The treatment with the highest removal ratio in each ash had the lowest pH. There was a significant correlation between pH and the Cl removal effect. The Cl remaining after the application of the methods was likely associated with Na.
There have been plenty of reports regarding the association between Vitamin D (Vit D) and carotid atherosclerosis and stroke. We aimed to assess the association between FokI and TaqI polymorphisms of vitamin D receptor (VDR) gene and the severity of carotid bulb stenosis and the incidence of carotid bulb calcification in patients with ischemic stroke.

This prospective study conducted at Shiraz University of Medical Sciences between February 2020 and August 2020. All consecutive patients with ischemic stroke with more than 50% carotid bulb stenosis in color doppler sonography underwent cervical CT angiography (CTA). Demographics, risk factors of ischemic stroke, serum calcium, phosphate, creatinine, serum 25-hydroxyvitamin D (Vit D) level were investigated by High-Performance Liquid Chromatography (HPLC) method. The severity of stenosis and presence of calcification in carotid bulb ipsilateral was studied in CTA to ischemic stroke. VDR genotypes of FokI and TaqI polymorphisms were determined by the Restriction FragmentLength Polymorphism (RFLP) method.
