Lee, Hwa-Jin published the artcileMechanism for Transition of Reverse Cylindrical Micelles to Spherical Micelles Induced by Diverse Alcohols, HPLC of Formula: 111-87-5, the main research area is reverse micelle lecithin calcium chloride propanol pentanol hexanol octanol.

Herein, the effects of various alcs. on lecithin/CaCl2 organogels are investigated. Mixtures of lecithin and CaCl2 form reverse cylindrical micelles, resulting in optically transparent organogels. The addition of various alcs. to a mixture of lecithin and CaCl2 induces a decrease in viscosity through which reverse cylindrical micelles are transformed into spherical micelles (or short cylindrical micelles). Long-hydrocarbon-chain alcs. decrease the viscosity of lecithin/CaCl2 mixtures more efficiently. Hydrogen bonding and hydrocarbon chain interactions between lecithin and alc. play important roles in the morphol. transition. More importantly, isothermal titration calorimetry was conducted to obtain thermodn. variables such as the enthalpy, equilibrium constant, Gibbs free energy, entropy, and stoichiometry of the associated mols. observed in the transition. It was found that the transition is an entropically driven process, in which the endothermic and exothermic behaviors were observed depending on the hydrocarbon chain length in the alc. In addition, the enthalpy for the association of the alc. with lecithin showed a linear relationship depending on the hydrocarbon chain length, in which the magnitude of hydrogen bonding and hydrocarbon chain interactions was obtained quant. To the best of our knowledge, this is the first study reporting the thermodn. properties of the morphol. transition observed in a reverse self-assembly process.

Miklas, Jason W. published the artcileAmino acid primed mTOR activity is essential for heart regeneration, Product Details of C4H6O5, the main research area is heart disease regeneration mTOR amino acid; Biological sciences; Cell biology; Tissue Engineering.

Heart disease is the leading cause of death with no method to repair damaged myocardium due to the limited proliferative capacity of adult cardiomyocytes. Curiously, mouse neonates and zebrafish can regenerate their hearts via cardiomyocyte de-differentiation and proliferation. However, a mol. mechanism of why these cardiomyocytes can re-enter cell cycle is poorly understood. Here, we identify a unique metabolic state that primes adult zebrafish and neonatal mouse ventricular cardiomyocytes to proliferate. Zebrafish and neonatal mouse hearts display elevated glutamine levels, predisposing them to amino-acid-driven activation of TOR, and that TOR activation is required for zebrafish cardiomyocyte regeneration in vivo. Through a multi-omics approach with cellular validation we identify metabolic and mitochondrial changes during the first week of regeneration. These data suggest that regeneration of zebrafish myocardium is driven by metabolic remodeling and reveals a unique metabolic regulator, TOR-primed state, in which zebrafish and mammalian cardiomyocytes are regeneration competent.

Diaz-Galvez, Kevin R. published the artcileSpecific capture of glycosylated graphene oxide by an asialoglycoprotein receptor: a strategic approach for liver-targeting, Related Products of alcohols-buliding-blocks, the main research area is hepatic cancer glycosylated graphene oxide asialoglycoprotein receptor.

In this work, we report the evaluation of lactosylated graphene oxide (GO-AL) as a potential drug carrier targeted at an asialoglycoprotein receptor (ASGPR) from hepatic cancer cells. Structural-modification, safety evaluation, and functional anal. of GO-AL were performed. Safe application of GO-AL, an evaluation of the cytotoxic effect, hemolytic properties, and specific interactions of the glycoconjugate were also studied. SEM and AFM anal. of the GO showed graphene sheets with a layer size of 2-3 nm, though a few of them reached 4 nm. The Raman spectra presented characteristic peaks of graphene oxide at 1608 cm-1 and 1350 cm-1, corresponding to G and D bands, resp. Besides, Si-O peaks for the APTES conjugates of GO were identified by FTIR spectroscopy. No cytotoxic or hemolytic effects were observed for GO samples, thus proving their biocompatibility. The interaction of Ricinus communis lectin confirmed that GO-AL has a biorecognition capability and an exposed galactose structure. This biorecognition capability was accompanied by the determination of the specific absorption of lactosylated GO by HepG2 cells mediated through the asialoglycoprotein receptor. The successful conjugation, hemolytic safety, and specific recognition described here for lactosylated GO indicate its promise as an efficient drug-delivery vehicle to hepatic tissue.

Pichaud, Nicolas published the artcileAdjustments of cardiac mitochondrial phenotype in a warmer thermal habitat is associated with oxidative stress in European perch, Perca fluviatilis, Quality Control of 97-67-6, the main research area is pyruvate malate mitochondria climate change oxidative stress Perca.

Mitochondria are playing key roles in setting the thermal limits of fish, but how these organelles participate in selection mechanisms during extreme thermal events associated with climate warming in natural populations is unclear. Here, we investigated the thermal effects on mitochondrial metabolism, oxidative stress, and mitochondrial gene expression in cardiac tissues of European perch (Perca fluviatilis) collected from an artificially heated ecosystem, the “”Biotest enclosure””, and an adjacent reference area in the Baltic sea with normal temperatures (∼ 23°C and ∼ 16°C, resp., at the time of capture in summer). Fish were sampled one month after a heat wave that caused the Biotest temperatures to peak at ∼ 31.5°C, causing significant mortality. When assayed at 23°C, Biotest perch maintained high mitochondrial capacities, while reference perch displayed depressed mitochondrial functions relative to measurements at 16°C. Moreover, mitochondrial gene expression of nd4 (mitochondrial subunit of complex I) was higher in Biotest fish, likely explaining the increased respiration rates observed in this population. Nonetheless, cardiac tissue from Biotest perch displayed higher levels of oxidative damage, which may have resulted from their chronically warm habitat, as well as the extreme temperatures encountered during the preceding summer heat wave. We conclude that eurythermal fish such as perch are able to adjust and maintain mitochondrial capacities of highly aerobic organs such as the heart when exposed to a warming environment as predicted with climate change. However, this might come at the expense of exacerbated oxidative stress, potentially threatening performance in nature.

Gao, Xindi published the artcileCryptococcal Hsf3 controls intramitochondrial ROS homeostasis by regulating the respiratory process, HPLC of Formula: 97-67-6, the main research area is Hsf3 ROS unfolded protein response electron transfer Cryptococcus.

Mitochondrial quality control prevents accumulation of intramitochondrial-derived reactive oxygen species (mtROS), thereby protecting cells against DNA damage, genome instability, and programmed cell death. However, underlying mechanisms are incompletely understood, particularly in fungal species. Here, we show that Cryptococcus neoformans heat shock factor 3 (CnHsf3) exhibits an atypical function in regulating mtROS independent of the unfolded protein response. CnHsf3 acts in nuclei and mitochondria, and nuclear- and mitochondrial-targeting signals are required for its organelle-specific functions. It represses the expression of genes involved in the tricarboxylic acid cycle while promoting expression of genes involved in electron transfer chain. In addition, CnHsf3 responds to multiple intramitochondrial stresses; this response is mediated by oxidation of the cysteine residue on its DNA binding domain, which enhances DNA binding. Our results reveal a function of HSF proteins in regulating mtROS homeostasis that is independent of the unfolded protein response.

Evans, Heather M. published the artcileRestraint of fumarate accrual by HIF-1α preserves miR-27a-mediated limitation of interleukin 10 during infection of macrophages by Histoplasma capsulatum, Product Details of C4H6O5, the main research area is HIF1alpha mir27a IL10 macrophages Histoplasma; Histoplasma; hypoxia inducible factor 1; innate immunity; lung; mitochondrial metabolism.

Hypoxia-inducible factor 1α (HIF-1α) regulates the immunometabolic phenotype of macrophages, including the orchestration of inflammatory and antimicrobial processes. Macrophages deficient in HIF-1α produce excessive quantities of the anti-inflammatory cytokine interleukin 10 (IL-10) during infection with the intracellular fungal pathogen Histoplasma capsulatum. Thus, the macrophage fails to become activated in response to proinflammatory cytokines and remains the intracellular niche of the pathogen. Here, we identify the tricarboxylic acid (TCA) cycle metabolite fumarate as the driver of IL-10 during macrophage infection with H. capsulatum in the absence of HIF-1α. Accumulation of fumarate reduced expression of a HIF-1α-dependent microRNA (miRNA), miR-27a, known to mediate decay of Il10 mRNA. Inhibition of fumarate accrual in vivo limited IL-10 and fungal growth. Our data demonstrate the critical role of HIF-1α in shaping appropriate TCA cycle activity in response to infection and highlight the consequences of a dysregulated immunometabolic response.

Aksakal, Suzan published the artcileTransformation of Thioester-Initiated Star Polymers into Linear Arms via Native Chemical Ligation, Application In Synthesis of 7575-23-7, the main research area is thioester initiated linear arm star polymer native chem ligation; copper-mediated polymerization; native chemical ligation; star polymers; thioester initiators.

The synthesis of a new class of Cu-mediated polymerization initiators with thioester functionality is demonstrated and their polymerization kinetics via single-electron transfer living radical polymerization is reported. From periodic sampling, it is found that thioester- or ester-based initiators can be employed interchangeably, resulting in very similar polymerization rates. Furthermore, a multifunctional thioester initiator is employed for the preparation of a well-defined four-arm star-shaped polymer. It is further shown that the full dissociation of the star polymer into linear arms via native chem. ligation can easily be followed via size exclusion chromatog., as a result of the change in hydrodynamic volume Finally, the obtained linear polymers are characterized via matrix-assisted laser desorption/ionization-time of flight mass spectrometry and found to be in good agreement with the expected mol. weight distribution that confirms the successful transformation.

Lu, Yao published the artcileEffects of spontaneous fermentation on the microorganisms diversity and volatile compounds during ‘Marselan’ from grape to wine, Product Details of C4H10OS, the main research area is spontaneous fermentation volatile compound marselan grape wine.

‘Marselan is a promising wine grapevine with unique qualities, studies on its introduction and characteristics have never stopped. However, little is known about the fermentation process of ‘Marselan wine. In this study, we compared industrial-scale spontaneous (SMF) and inoculated (IMF) fermentation processes on the succession of microbial community and the change in volatile compounds and predicted their correlations. SMF could ferment ‘Marselan to dry red wine with alc. content of 13.37% ± 0.76% (volume/volume) in 10 days and enhance the total concentration and odor activity values (OAVs) of volatile compounds Et caprylate, Et caprate, Et caproate and citronellol (OAVs > 1.0) were important volatile compounds in SMF and IMF wines. Compared with IMF, SMF was more outstanding in initial non-Saccharomyces diversity, including Hanseniaspora, Metschnikowia and Issatchenkia. In addition, Spearmans correlation (|ρ| > 0.7) and bidirectional orthogonal partial least squares (O2PLS, VIP > 1.0) anal. showed that some indigenous microorganisms in grape were closely related to the formation of volatile compounds, such as lactic acid bacteria, non-Saccharomyces and Saccharomyces cerevisiae. Overall, results showed that SMF could strengthen the flavor of ‘Marselan’ wine, and the possibility of consideration screening indigenous aroma-producing microorganisms as starter to improve the unique characteristics of ‘Marselan wine.

Kikuchi-Taura, Akie published the artcileGap junction-mediated cell-cell interaction between transplanted mesenchymal stem cells and vascular endothelium in stroke, HPLC of Formula: 111-87-5, the main research area is cell gap junction communication stemcell transplantation vascular endothelium stroke; COVID-19; cell therapy; gap junction; immunosuppression; mesenchymal stem cell.

We have shown previously that transplanted bone marrow mononuclear cells (BM-MNC), which are a cell fraction rich in hematopoietic stem cells, can activate cerebral endothelial cells via gap junction-mediated cell-cell interaction. In the present study, we investigated such cell-cell interaction between mesenchymal stem cells (MSC) and cerebral endothelial cells. In contrast to BM-MNC, for MSC we observed suppression of vascular endothelial growth factor uptake into endothelial cells and transfer of glucose from endothelial cells to MSC in vitro. The transfer of such a small mol. from MSC to vascular endothelium was subsequently confirmed in vivo and was followed by suppressed activation of macrophage/microglia in stroke mice. The suppressive effect was absent by blockade of gap junction at MSC. Furthermore, gap junction-mediated cell-cell interaction was observed between circulating white blood cells and MSC. Our findings indicate that gap junction-mediated cell-cell interaction is one of the major pathways for MSC-mediated suppression of inflammation in the brain following stroke and provides a novel strategy to maintain the blood-brain barrier in injured brain. Furthermore, our current results have the potential to provide a novel insight for other ongoing clin. trials that make use of MSC transplantation aiming to suppress excess inflammation, as well as other diseases such as COVID-19 (coronavirus disease 2019).
