Knowledge of electrolyte transport and thermodn. properties in Li-ion and beyond Li-ion technologies is vital for their continued development and success. Here, we present a method for fully characterizing electrolyte systems. By measuring the electrolyte concentration gradient over time via operando Raman microspectroscopy, in tandem with potentiostatic electrochem. impedance spectroscopy, the Fickian “”apparent”” diffusion coefficient, transference number, thermodn. factor, ionic conductivity and resistance of charge-transfer were quantified within a single exptl. setup. Using lithium bis(fluorosulfonyl)imide (LiFSI) in tetraglyme (G4) as a model system, our study provides a visualisation of the electrolyte concentration gradient; a method for determining key electrolyte properties, and a necessary technique for correlating bulk intermol. electrolyte structure with the described transport and thermodn. properties.

Feng, Qian; Liu, Huan; Peng, Zhigang; Zheng, Yong published the artcile< Synthesis, characterization and evaluation of long-acting hyperbranched cationic polymer clay stabilizer used in water flooding>, Computed Properties of 112-63-0, the main research area is polymer clay stabilizer water flooding.

In the process of waterflooding development, it is of great importance to prevent the clay from hydration swelling and migration dispersion for protecting the formation and improving the water flooding efficiency. For those reasons, we successfully synthesized a cationic clay stabilizer (HBP-QAT) through melting polycondensation and cationic modification with maleic anhydride, diethanolamine, epichlorohydrin, triethylamine, and trimethylolpropane as monomers and p-toluene sulfonic acid as a catalyst. The chem. structure, cation degree, and mol. weight of HBP-QAT were studied by using FTIR, 1H NMR, sodium tetraphenylborate (STBP) back titration, and gel permeation chromatog. (GPC). The obtained results showed that HBP-QAT was a hyperbranched unsaturated polyester amide with a low mol. weight and a high cation degree, with corresponding values of 28400, and 44.2%, resp. The clay stability and durability of HBP-QAT were evaluated by linear anti-swelling, water flushing, and cutting rolling recovery tests. The obtained results showed that HBP-QAT has an excellent anti-washing capacity and a long-term inhibition effect. The initial anti-swelling rate of 1.0 wt% HBP-QAT reached 92.37%, and the anti-swelling rate of 1.0 wt% HBP-QAT also remained at 85% after flushing 10 times with water. Besides, the two cutting rolling recoveries exceed 72%. Most importantly, the inhibition mechanism of HBP-QAT was studied by zeta potential, X-ray diffraction (XRD), XPS, scanning electron microscope (SEM), and contact angles analyses, and thus we proposed an inhibition mechanism, presenting as follows. HBP-QAT inhibited the clay hydration swelling by neutralizing neg. charges on the surface of the clay particles to compress the elec. double layer, strongly adsorbing on the surface of the clay particles, and forming a waterproof polymer membranes, restraining water of intrusion into the clay interlayer.

Loss-of-function mutations in genes encoding the Krebs cycle enzymes Fumarate Hydratase (FH) and Succinate Dehydrogenase (SDH) induce accumulation of fumarate and succinate, respectively and predispose patients to hereditary cancer syndromes including the development of aggressive renal cell carcinoma (RCC). Fumarate and succinate competitively inhibit αKG-dependent dioxygenases, including Lysine-specific demethylase 4A/B (KDM4A/B), leading to suppression of the homologous recombination (HR) DNA repair pathway. In this study, we have developed new syngeneic Fh1- and Sdhb-deficient murine models of RCC, which demonstrate the expected accumulation of fumarate and succinate, alterations in the transcriptomic and methylation profile, and an increase in unresolved DNA double-strand breaks (DSBs). The efficacy of poly ADP-ribose polymerase inhibitors (PARPis) and temozolomide (TMZ), alone and in combination, was evaluated both in vitro and in vivo. Combination treatment with PARPi and TMZ results in marked in vitro cytotoxicity in Fh1- and Sdhb-deficient cells. In vivo, treatment with standard dosing of the PARP inhibitor BGB-290 and low-dose TMZ significantly inhibits tumor growth without a significant increase in toxicity. These findings provide the basis for a novel therapeutic strategy exploiting HR deficiency in FH and SDH-deficient RCC with combined PARP inhibition and low-dose alkylating chemotherapy.

We report on the design of glycosylated nanogels via core-crosslinking of amphiphilic non-water-soluble block copolymers composed of an acetylated glycosylated block and a pentafluorophenyl (PFP) activated ester block prepared by reversible addition-fragmentation (RAFT) polymerization Self-assembly, pH-sensitive core-crosslinking, and removal of remaining PFP esters and protecting groups are achieved in one pot and yield fully hydrated sub-100 nm nanogels. Using cell subsets that exhibit high and low expression of the mannose receptor (MR) under conditions that suppress active endocytosis, we show that mannosylated but not galactosylated nanogels can efficiently target the MR that is expressed on the cell surface of primary dendritic cells (DCs). These nanogels hold promise for immunol. applications involving DCs and macrophage subsets.

Abraham, Michael H. published the artcile< Hydrogen bonding. XXVII. Solvation parameters for functionally substituted aromatic compounds and heterocyclic compounds, from gas-liquid chromatographic data>, HPLC of Formula: 112-63-0, the main research area is solvation parameter calculation aromatic compound chromatog; gas chromatog determination solute polarizability parameter; hydrogen bond solvation parameter gas chromatog; heterocyclic compound solvation parameter gas chromatog; retention equation gas chromatog aromatic compound; nonpolar stationary phase gas chromatog retention; linear free energy relationship gas chromatog.

The truncated solvation equation log SP = c + rR2 + l(log L16) was applied to a very large number of sets of gas-liquid chromatog. data on nonpolar stationary phases. The parameter log SP (SP = a solvation parameter) can be log VG (specific retention volume at the column temperature) or can be the retention index I; R2 is the excess molar refraction of the solute and c, r and l are constants A set of solutes of known log L16 values is used to construct the equation, and then further values of log L16 can be obtained for any solute of known log SP value. In this way, new log L16 values for > 1000 solutes were obtained. Known log L16 and R2 values are substituted into the equation log SP = c + rR2 + sπH2 + l(log L16) (s is a constant) so that it can be applied to GLC data on polar non-acidic stationary phases, and the dipolarity/polarizability parameter πH2 is determined in a similar fashion. Values of πH2 for > 700 compounds are reported, including those for functionally substituted aromatic compounds and heterocyclic compounds The πH2 parameter is a blend of dipolarity/polarizability, and cannot be calculated simply from solute dipole moments.

Literature reports growing concern on ever-burgeoning list of irrational fixed dose combinations (FDCs) flooding the Indian market. Current study addresses availability and rationality of two most common group of FDC used clin., i.e., antimicrobial (AM) and antidiarrheal (AD). Anal. of rationality of AM and AD, FDCs, and available in Indian market. AM and AD, FDCs listed in Indian Drug Review 2017 and 2018, were analyzed using a validated eight- point criteria tool. Out of 138 FDCs, 102 (73.91%) belonged to AM group and 36 (26.08%) belonged to AD group. Out of 102 AM FDC′s, 46 (45.09%) were rational and 56 (54.90%) were irrational. Out of 36 AD, FDCs, 10 (27.77%) were rational and 26 (72.22%) were irrational. Mean rationality score of AM and AD, FDC′s, was (7.72 ± 0.33) and (7.5 ± 0.78), resp. Anal. reveals that a number of FDCs available in Indian market is irrational.

Although protein-protein interactions (PPIs) have emerged as an attractive therapeutic target space, the identification of chems. that effectively inhibit PPIs remains challenging. Here, we identified through library screening a chem. probe (compound 1) that can inhibit the tumor-promoting interaction between the oncogenic factor exon 2-depleted splice variant of aminoacyl-tRNA synthetase-interacting multifunctional protein 2 (AIMP2-DX2) and heat shock protein 70 (HSP70). We found that compound 1 binds to the N-terminal subdomain of glutathione S-transferase (GST-N) of AIMP2-DX2, causing a direct steric clash with HSP70 and an intramol. interaction between the N-terminal flexible region and the GST-N of AIMP2-DX2, which induces masking of the HSP70 binding region during mol. dynamics and mutation studies. Compound 1 thus interferes with the AIMP2-DX2 and HSP70 interaction and suppresses the growth of cancer cells that express high levels of AIMP2-DX2 in vitro and in preliminary in vivo experiment This work provides an example showing that allosteric conformational changes induced by chems. can be a way to control pathol. PPIs.
