In recent times, there has been a surge in interest regarding the synthesis of Janus particles using biological macromolecules. Various synthesis techniques have been developed for the fabrication of Janus materials derived from biomass.

Preparation of Polyimide/Ionic Liquid Hybrid Membrane for CO/CH Separation.

Imidazole ionic liquids (IL) have good affinity and good solubility for carbon dioxide (CO). Such ionic liquids, combined with polyimide membrane materials, can solve the problem that, today, CO is difficult to separate and recover. In this study, the ionic liquid (IL) of 1-ethyl-3-methylimidazolium tetrafluoroborate (IL), 1-pentyl-3-methylimidazolium tetrafluoroborate (IL), 1-octyl-3-methylimidazolium tetrafluoroborate (IL), and 1-dodecylimidazolium tetrafluoroborate (IL) with different contents were added to a polyimide matrix, and a series of polyimide membranes blended with ionic liquid were prepared using a high-speed mixer.

Preparation and Separation Properties of Electrospinning Modified Membrane with Ionic Liquid Terminating Polyimide/Polyvinylpyrrolidone@Polydopamine.

In this paper, superhydrophilic polyimide (PI) membranes were prepared using the electrostatic spinning method, capped with a hydrophilic ionic liquid (IL), and blended with polyvinylpyrrolidone (PVP). Using this preparation, the surface of the fiber membranes was coated in polydopamine (PDA) by means of an in-growth method. Scanning electron micrographs showed prepared blend films can form continuous fibers, for whom the distributions of diameter and pore were uniform.

Preparation of Butadiene-Bridged Polymethylsiloxane/Ethylcellulose/1-Carboxymethyl-3-methylimidazolium Chloride Ternary Composite Membranes for Gas Separation.

Excessive CO emissions have resulted in global warming and are a serious threat to the life of people, various strategies have been implemented to cut carbon emissions, and one of them is the use of a gas separation membrane to capture CO effectively. In this experiment, the butadiene-bridged polymethylsiloxane (BBPMS)/ethyl cellulose (EC)/ionic liquid (IL) ternary composite membranes were prepared by EC as a substrate, BBPMS, and IL as additives in tetrahydrofuran under high-speed stirring and coated on the membrane. The membrane structure was characterized by a Fourier transform infrared spectrometer and scanning electron microscope, and the membrane properties were tested by a membrane tensile strength tester, thermal weight loss analyzer, and gas permeability meter.

Optimization of a MOF Blended with Modified Polyimide Membrane for High-Performance Gas Separation.

The preparation, characterization and gas separation properties of mixed matrix membranes (MMMs) were obtained from polyimide capped with ionic liquid and blended with metal-organic frameworks (MOFs). The synthesized MOF was amine functionalized to produce UiO-66-NH, and its amino group has a higher affinity for CO. Mixed matrix membranes exhibited good membrane forming ability, heat resistance and mechanical properties.

Clinical analysis of total endoscopic thyroidectomy via breast areola approach in early differentiated thyroid cancer.

Purpose: The purpose of this study was to explore the efficacy and safety of total endoscopic thyroidectomy (TET) via breast areola approach in the treatment of early differentiated thyroid cancer.

Methods: The clinical data of 134 patients with early differentiated thyroid cancer were retrospectively analyzed. The patients underwent different treatments, including TET via breast areola approach in endoscope group (n=67), and conventional small incision open surgery in control group (n=67).

Expression levels of ARHI and Beclin1 in thyroid cancer and their relationship with clinical pathology and prognosis.

Expression levels of autophagy-related genes ARHI and Beclin1 in thyroid cancer and their relationship with clinical pathology and prognosis were investigated. The expression levels of ARHI and Beclin1 proteins in 80 cases of thyroid cancer and adjacent tissues were detected by western blot analysis. According to the expression levels of ARHI and Beclin1, low- and high-expression groups were determined and the relationship of the expression levels with the pathological parameters and prognosis in thyroid cancer was compared between the two groups.

Herb-drug interaction prediction based on the high specific inhibition of andrographolide derivatives towards UDP-glucuronosyltransferase (UGT) 2B7.

Herb-drug interaction strongly limits the clinical application of herbs and drugs, and the inhibition of herbal components towards important drug-metabolizing enzymes (DMEs) has been regarded as one of the most important reasons. The present study aims to investigate the inhibition potential of andrographolide derivatives towards one of the most important phase II DMEs UDP-glucuronosyltransferases (UGTs). Recombinant UGT isoforms (except UGT1A4)-catalyzed 4-methylumbelliferone (4-MU) glucuronidation reaction and UGT1A4-catalyzed trifluoperazine (TFP) glucuronidation were employed to firstly screen the andrographolide derivatives' inhibition potential.

Glucuronidation of aurantio-obtusin: identification of human UDP-glucuronosyltransferases and species differences.

1. The aurantio-obtusin's glucuronide was detected when aurantio-obtusin was incubated with human liver microsomes (HLMs). Recombinant UGT isoforms screening experiment showed that UGT1A8 was the major isoform contributed to the glucuronidation.

Onset of cooperation between layered networks.

Functionalities of a variety of complex systems involve cooperations among multiple components; for example, a transportation system provides convenient transfers among airlines, railways, roads, and shipping lines. A layered model with interacting networks can facilitate the description and analysis of such systems. In this paper we propose a model of traffic dynamics and reveal a transition at the onset of cooperation between layered networks.

Reversible inhibition of four important human liver cytochrome P450 enzymes by diethylstilbestrol.

Diethylstilbestrol (DES), a synthetic estrogen clinically used to treat threatened abortion between the 1940s and the 1970s, has been restricted to treat certain cases of prostatic and breast cancer due to its adverse drug responses such as teratogenicity and carcinogenicity. Some reports have demonstrated that the addition of DES to docetaxel could modify tubulin composition and improve response of prostate cancer to chemotherapy. Given that DES might be co-administered with other drugs such as docetaxel, the present study focused on CYP-based drug-drug interaction (DDI).

Substrate-dependent modulation of the catalytic activity of CYP3A by erlotinib.

Aim: To ascertain the effects of erlotinib on CYP3A, to investigate the amplitude and kinetics of erlotinib-mediated inhibition of seven major CYP isoforms in human liver microsomes (HLMs) for evaluating the magnitude of erlotinib in drug-drug interaction in vivo.

Methods: The activities of 7 major CYP isoforms (CYP1A2, CYP2A6, CYP3A, CYP2C9, CYP2D6, CYP2C8, and CYP2E1) were assessed in HLMs using HPLC or UFLC analysis. A two-step incubation method was used to examine the time-dependent inhibition of erlotinib on CYP3A.
