Hinokiflavone and Related C-O-C-Type Biflavonoids as Anti-cancer Compounds: Properties and Mechanism of Action

Biflavonoids are divided in two classes: C-C type compounds represented by the dimeric compound amentoflavone and C-O-C-type compounds typified by hinokiflavone (HNK) with an ether linkage between the two connected apigenin units. This later sub-group of bisflavonyl ethers includes HNK, ochnaflavone, delicaflavone and a few other dimeric compounds, found in a variety of plants, notably Selaginella species. A comprehensive review of the anticancer properties and mechanism of action of HNK is provided, to highlight the anti-proliferative and anti-metastatic activities of HNK and derivatives, and HNK-containing plant extracts. The anticancer effects rely on the capacity of HNK to interfere with the ERK1-2/p38/NF kappa B signaling pathway and the regulation of the expression of the matrix metalloproteinases MMP-2 and MMP-9 (with a potential direct binding to MMP-9). In addition, HNK was found to function as a potent modulator of pre-mRNA splicing, inhibiting the SUMO-specific protease SENP1. As such, HNK represents a rare SENP1 inhibitor of natural origin and a scaffold to design synthetic compounds. Oral formulations of HNK have been elaborated to enhance its solubility, to facilitate the compound delivery and to enhance its anticancer efficacy. The review shed light on the anticancer potential of C-O-C-type biflavonoids and specifically on the pharmacological profile of HNK. This compound deserves further attention as a regulator of pre-mRNA splicing, useful to treat cancers (in particular hepatocellular carcinoma) and other human pathologies.

Methyl tertiary-butyl ether inhibits THP-1 macrophage cholesterol efflux in vitro and accelerates atherosclerosis in ApoE-deficient mice in vivo

The biosafety of methyl tertiary -butyl ether (MTBE), mainly used as a gasoline additive, has long been a contentious topic. In addition to its routine toxicities, MTBE has been demonstrated to disrupt glucose and lipid metabolism and contribute to the development of type 2 diabetes as well as obesity. As one of the morbidities related to dyslipidemia, atherosclerosis is worthy of being investigated under MTBE exposure. Since foam cells derived from macrophages play pivotal roles during atherosclerosis development, we studied the effects of MTBE on macrophages in vitro and assessed the effect of MTBE on atherosclerosis plaque formation with the ApoE(-/-) mouse model in vivo for the first time. Our results demonstrated that exposure to MTBE at environmentally relevant concentrations decreased the expression of ABCA1 and ABCG1, which are responsible for macrophage cholesterol efflux, at both mRNA and protein levels in THP-1 macrophages. Consequently, treatment with MTBE inhibited the transport of cholesterol from macrophages to High -density lipoprotein. ApoE(-/-)mice exposed to MTBE at environmentally relevant concentrations (100, 1000 p.g/kg) displayed significant increases in lesion area in the aorta and aortic root compared to vehicle treated ones. Further analysis indicated that MTBE exposure enhanced the macrophage specific marker Mac -2 contents within plaques in the aortic root, implying that MTBE could promote macrophage -derived foam cell formation and thus accelerate atherosclerosis plaque formation. We for the first time demonstrated the pro-atherogenic effect of MTBE via eliciting disruption of macrophage cholesterol efflux and accelerating foam cell formation and atherosclerosis plaque development.

Novel highly efficient branched polyfluoro sulfonated polyimide membranes for application in vanadium redox flow battery

Branched polyfluom sulfonated polyimide (BPFSPI) membranes with different degree of branching and degree of sulfonation are designed and prepared for application in vanadium redox flow battery (VRFB). The optimized BPFSPI-10-50 membrane exhibits a similar proton conductivity (2.94 x 10(-2) S cm(-1)) as that of the commercial Nafion 212 membrane (3.20 x 10(-2) S cm(-1)) and a much higher membrane selectivity (3.16 x 10(5) S min cm(-3)) than Nafion 212 membrane (0.42 x 10(5) S min cm(-3)). Meanwhile, BPFSPI-10-50 membrane is durable in V(V) + H2SO4 solutions for more than 30 d. Both coulomb efficiency (CE) and energy efficiency (EE) of BPFSPI-10-50 membrane are higher than those of Nafion 212 membrane (CE: 94.2-98.9% vs 73.9-94.9%, EE: 68.0-86.9% vs 67.7-77.9%) in VRFB (40-200 mA cm(-2)) test. Besides, BPFSPI-10-50 membrane displays slower self-discharge rate and excellent discharge capacity retention compared to Nafion 212 membrane. Furthermore, the VRFB with BPFSPI-10-50 membrane shows very stable CE and EE (>98% and 76%) over 200 charge-discharge cycles. Accordingly, the BPFSPI-10-50 membrane with superior cost-performance ratio has an outstanding prospect for application in VRFB.

The significance of the interfacial interaction in mixed matrix membranes for enhanced propylene/propane separation performance and plasticization resistance

Mixed matrix membranes (MMMs) are an attractive platform for challenging gas separations since they are the state-of-the-art scalable molecular sieve membranes. Here, the commercially attractive polysulfone (PSF) was grafted by poly(polyethylene glycol) methyl ether methacrylate (PEG) side chains to improve the interfacial interaction with zeolitic imidazolate framework-8 (ZIF-8) nanoparticles and the affinity towards C3H6 for enhanced C3H6/C3H8 separation performance. The PSFPEG graft copolymers monotonically increased the intersegmental distance of polymer chains with increasing the PEG contents based on the XRD results and the density functional theory calculations. Also, the cross-sectional SEM images of MMMs visualized that the interfacial adhesion between ZIF-8 and polymer was improved as the PEG content increased. Both DSC and FT-IR analyses revealed that such an enhanced interfacial adhesion was attributed to a combination of flexible nature of PEG side chains and various chemical interactions. More importantly, the PSFPEG73/ZIF-8 (65/35 vol/vol) MMM enhanced both C3H6 permeability and C3H6/C3H8 permselectivity compared to the PSF/ZIF-8 counterpart by 57% and 55%, respectively. Besides, the equimolar C3H6/C3H8 mixed gas permeation isotherm exhibited that the PSFPEG73/ZIF-8 (65/35 vol/vol) MMM enhanced the plasticization resistance against C3H6 compared to the PSF/ZIF-8 counterpart (e.g., C3H6-induced plasticization pressure of 5 vs. 3 atm), demonstrating the significance of the interfacial interaction.

A chemical-induced crystallization strategy to fabricate poly(ether ether ketone) asymmetric membranes for organic solvent nanofiltration

Developing of polymeric material with high stability is the key to the progress of organic solvent nanofiltration (OSN) membranes. As a semi-crystalline polymer with rigid aromatic backbone structure, poly(ether ether ketone) (PEEK) has good resistance to most of the organic solvents. However, the preparation of PEEK asymmetric membranes is hindered by its inherent insolubility in common solvents. In this work, a chemical-induced crystallization (CIC) strategy involving fabrication of asymmetric membranes from its precursor polymer-poly (ether ether ketimine) (PEEKI) and then converting to PEEK by acid treatment was proposed. The results indicated that the obtained membranes could be used stably in various organic solvents, and the optimal membrane exhibited a DMF permeance of 4.19 L m(2) h(-1) bar(-1) and a molecular weight cut-off of 350 g mol(-1) in DMF, which was an order of magnitude higher than the PEEK OSN membranes prepared from the sulfonic acid solvents. Meanwhile, the developed PEEK membranes also possessed good pressure resistance for long-term nanofiltration. Our study has proven the feasibility of fabrication PEEK asymmetric membranes through the CIC strategy for OSN application.

Dialkyl Sulfobetaine Surfactants Derived from Guerbet Alcohol Polyoxypropylene-Polyoxyethylene Ethers for SP Flooding of High Temperature and High Salinity Reservoirs

Dialkyl hydroxypropyl sulfobetaine (HSB) surfactants, C(16)GA-(PO)(5)-(EO)(3)-HSB and C(24)GA-(PO)(10)-(EO)(10)-HSB, were synthesized from Guerbet alcohols (GA) polyoxypropylene-polyoxyethylene (PO-EO) ethers and their behaviors in surfactant-polymer (SP) flooding of high temperature and high salinity reservoirs were examined and compared with their anionic hydroxypropyl sulfonate (HS) counterparts, C(16)GA-(PO)(5)-(EO)(3)-HS and C(24)GA-(PO)(10)-(EO)(10)-HS. The PO-EO chain embedded improves their aqueous solubility, and the sulfobetaines show better salt resistance than sulfonates. For a reservoir condition of total salinity 19,640 mg L-1 and 60-80 degrees C, C(16)GA-(PO)(5)-(EO)(3)-HSB alone can reduce crude oil/connate water interfacial tension (IFT) to ultralow at 0.25-5 mM, which can be further widened to 0.1-5 mM by mixing with dodecylhexyl (C12+6) glyceryl ether hydroxypropyl sulfobetaine (C(12+6)GE-HSB), a slightly hydrophobic surfactant. C(24)GA-(PO)(10)-(EO)(10)-HSB is more hydrophobic for the specified reservoir condition, however, by mixing with hexadecyl dimethyl hydroxypropyl sulfobetaine (C16HSB), a hydrophilic surfactant, ultralow IFT can also be achieved at a total concentration of 0.25-5 mM. The anionic counterparts can also reduce IFT to ultralow by mixing with C(12+6)GE-HSB and C16HSB, respectively. Moreover, the optimum binary mixture, C(16)GA-(PO)(5)-(EO)(3)-HSB/C(12+6)GE-HSB at a molar fraction ratio of 0.6/0.4, can keep the negatively charged solid surface water-wet (theta(w) = 12-23 degrees) in a wide concentration range, and can still achieve ultralow IFT after stored at 90 degrees C for 90 days (initially 5 mM), which overall are favor of improving oil displacement efficiency at high temperature and high salinity reservoir conditions.

Utility of an Automatic Vision-Based Examination System (AVE-562) for the Detection of Clonorchis sinensis Eggs in Stool

Stool examination is the gold standard for the detection of intestinal parasites. We assessed the performance of a newly developed AVE-562 analyzer (AVE Science & Technology Co., Hunan, China) for the vision-based detection of eggs of Clonorchis sinensis-the most common intestinal parasite in Korea-in stool samples. In total, 30 stool samples with a high or low egg count or without eggs (as negative control samples) (N=10 each) were prepared and analyzed. The performance of the AVE-562 analyzer was compared with that of the formalin-ether concentration (FEC) method. The overall correct identification rate of the AVE-562 analyzer based on FEC results was 66.6%. The sensitivity, specificity, positive predictive value, and negative predictive value of the AVE-562 analyzer for detecting C. sinensis eggs were 36.4%, 100.0%, 100.0%, and 73.1%, respectively. The average time required to run five tests simultaneously was 27 min using the AVE-562 analyzer and 58 min using the FEC method. Although the AVE-562 analyzer enables rapid and convenient stool examination, its sensitivity needs to be improved, particularly considering the prevalence of low-burden C. sinensis infection in Korea.

Aggregation-induced emission-active hyperbranched polymer-based nanoparticles and their biological imaging applications

Herein, we developed a facile one-pot approach to prepare amphiphilic aggregation-induced emission (AIE)-active hyperbranched fluorescent nanoparticles with a core-shell structure. This was conducted via the addition reaction between tetraphenylethylene (TPE)-OH, isophorone diisocyanate, and hyperbranched polyglycidol (HPG) using a one-pot method. The resultant AIE-active hyperbranched polymer structure was characterized by H-1 nuclear magnetic resonance and Fourier-transform infrared spectroscopy. The amphiphilic AIE-active polymer was prone to self-assemble in an aqueous solution to form core-shell type nanoparticles with a TPE core and hydroxyl groups on the core surface. The self-assembly of nanoparticles in the aqueous solution was characterized using dynamic light scattering, ultraviolet-visible spectroscopy, fluorescence spectroscopy, and transmission electron microscopy. Aggregation behavior of TPE-HPG polymer in water and diethyl ether was studied by dissipative particle dynamics simulation. Furthermore, these TPE-HPG nanoparticles exhibited a strong blue luminescence in the aqueous solution due to the aggregation of the AIE feature of TPE. These polymeric nanoparticles showed high water solubility, good photostability, and biological imaging properties. The cell viability assay and confocal microscopy imaging results suggested that the TPE-HPG fluorescent polymeric organic nanoparticles (FPNs) have low cytotoxicity and excellent biocompatibility. Thus, TPE-HPG FPNs are excellent candidates for biomedical applications.

Dysregulated Lipid Metabolism Precedes Onset of Psychosis

BACKGROUND: A key clinical challenge in the management of individuals at clinical high risk for psychosis (CHR) is that it is difficult to predict their future clinical outcomes. Here, we investigated if the levels of circulating molecular lipids are related to adverse clinical outcomes in this group. METHODS: Serum lipidomic analysis was performed in 263 CHR individuals and 51 healthy control subjects, who were then clinically monitored for up to 5 years. Machine learning was used to identify lipid profiles that discriminated between CHR and control subjects, and between subgroups of CHR subjects with distinct clinical outcomes. RESULTS: At baseline, compared with control subjects, CHR subjects (independent of outcome) had higher levels of triacylglycerols with a low acyl carbon number and a double bond count, as well as higher levels of lipids in general. CHR subjects who subsequently developed psychosis (n = 50) were distinguished from those that did not (n = 213) on the basis of lipid profile at baseline using a model with an area under the receiver operating curve of 0.81 (95% confidence interval = 0.69-0.93). CHR subjects who became psychotic had lower levels of ether phospholipids than CHR individuals who did not (p < .01). CONCLUSIONS: Collectively, these data suggest that lipidomic abnormalities predate the onset of psychosis and that blood lipidomic measures may be useful in predicting which CHR individuals are most likely to develop psychosis. Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.

Dielectric properties of sulfonated poly(ether ether ketone) (SPEEK) electrolytes with 1-ethyl-3-methylimidazolium tetrafluoroborate salt: Ionic liquid-based conduction pathways

In this study, dielectric properties of sulfonated poly(ether ether ketone) (SPEEK) solid polymer electrolytes (SPEs) containing room-temperature molten salt, 1-ethyl-3-methylimidazolium tetrafluoroborate were investigated. Additionally, the effects of ionic liquid (IL) addition on the thermomechanical properties and the microstructure of composite electrolytes (SPEEK-30 x 1IM and SPEEK-30 x 2IM) were studied. The characteristics of the SPEs were investigated by FTIR, SEM, TGA, DSC and DMA measurements. FTIR analysis confirmed the success of the sulfonation process and IL/sulfonated polymer interactions. IL addition caused changes in the crystalline structure and surface morphology of the SPEs. It was observed that SPEEK-30 x 1IM and SPEEK-30 x 2IM electrolytes have lower glass transition temperatures (T-g) and crystallinity than that of pure SPEEK-30. Due to the amorphous character formed by IL, proton conduction paths in which ILs exhibit enhanced conductivity have been formed. Among the composite electrolytes, SPEEK-30 x 2IM demonstrated an ionic conductivity (5.45 x 10(-4) Scm(-1)) more than 20 times higher than SPEEK-30.
