A water-compatible magnetic triclosan (TCS) imprinted material (TCS-CTS-Fe(0)-MIPs) was synthesized for selective enrichment and detection of TCS in real complex water samples. The material was synthesized by using chitosan (CTS) as functional monomer, which has rich surface O- and N-containing functional groups. The TCS imprinted CTS was coated on Fe(0) surface and then cross-linked with glutaraldehyde. Scanning electron microscopy suggested that the imprinted material was covered with a layer of imprinted film, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy confirmed that the imprinted material had more functional groups (amino and hydroxyl groups) than that of non-imprinted material...

PURPOSES: At the moment of sex reassignment surgery (SRS), the ovarian tissue is sometimes cryopreserved as fertility preservation option for female-to-male trans men, also called trans men. During this preparation, cumulus-oocyte-complexes (COCs) can be found and in vitro matured. It is not known if these oocytes are developmentally competent. In order to use these oocytes for fertility preservation and subsequent fertilization, a normal spindle structure before and after vitrification is necessary...

Intracellular compartmentalization and trafficking of molecules plays a critical role in complex and essential cellular processes. In lung cancer and other malignancies, aberrant nucleocytoplasmic transport of tumor suppressor proteins and cell cycle regulators results in tumorigenesis and inactivation of apoptosis. Pharmacologic targeting of this process, termed selective inhibition of nuclear export (SINE), has demonstrated anti-tumor efficacy in preclinical models and human clinical trials. Exportin-1 (XPO1)-which serves as the sole exporter of several tumor suppressor proteins and cell cycle regulators, including retinoblastoma (Rb), adenomatous polyposis coli (APC), p53, p73, p21, p27, FOXO, STAT3, IKB, topoisomerase II and PAR-4-is the principal focus of SINE drug development...

Hollow organs (e.g. heart) experience pressure-induced mechanical wall stress sensed by molecular mechano-biosensors, including mechanosensitive ion channels, to translate into intracellular signaling. For direct mechanistic studies, stretch devices to apply defined extensions to cells adhered to elastomeric membranes have stimulated mechanotransduction research. However, most engineered systems only exploit unilateral cellular stretch. In addition, it is often taken for granted that stretch applied by hardware translates 1:1 to the cell membrane...

In an effort to explore the residual complexity of naturally occurring chalcones from the roots of Glycyrrhiza inflata (Fabaceae), two new licochalcone A (LicA) derivatives were isolated as trace metabolites from enriched fractions. Both constituents contain a dihydrofuran moiety linked to carbons C-4 and C-5 of the retrochalcone core. Compound 1 (LicAF1) represents a new chemical entity, whereas compound 2 (LicAF2) has previously been reported as a Lewis acid catalyzed rearrangement of LicA. Evaluation of chirality revealed that both dihydrofuran derivatives existed as a mixture of R and S enantiomers...

Resveratrol (Rsv) is widely reported to possess anticarcinogenic properties in a plethora of cellular and animal models having limited toxicity toward normal cells. In the molecular level, Rsv can act as a suppressive agent for several impaired signaling pathways on cancer cells. However, Fukuhara and Miyata have shown a non-proteic reaction of Rsv, which can act as a prooxidant agent in the presence of copper (Cu), causing cellular oxidative stress accompanied of DNA damage. After this discovery, the complex Rsv-Cu was broadly explored as an antitumor mechanism in multiples tumor cell lines...

Inhibitor of Apoptosis Proteins (IAPs) are critical regulators of cell death and survival pathways. Mice lacking cellular IAP (cIAP) 1 and either cIAP2 or X-linked IAP (XIAP) die in utero, and myeloid lineage-specific deletion of all IAPs causes sterile inflammation, but their role in the skin is unknown. We generated epidermal-specific IAPs deficient mice and found that combined genetic deletion of cIAP1 in keratinocytes and ubiquitous cIAP2 deletion (cIap1(EKO/EKO).cIap2(-/-)) caused profound skin inflammation and keratinocyte death, lethal by post-partum day 10...

The ratio of different AA in the diets of cows is vital to improve milk protein yield. β-Casein is one of the important milk proteins with high nutritive value. However, the suitable ratio of essential amino acids (EAA) for the expression of β-casein in the immortalized bovine mammary epithelial cell line is not fully characterized. This study employed response surface methodology to determine the optimal ratio of His, Lys, Met, and Leu on β-casein expression level in vitro and clarified the effect of the 4 EAA on β-casein via the mechanistic target of rapamycin (mTOR) signaling pathway...

The pesticide atrazine, its degradation products, and 2,6-dichlorobenzamide (BAM) are persistent in groundwater environment. We studied whether their dissipation can be enhanced with a mixture of a complex carbon source and zero-valent iron (ZVI) called EHC®. The application rates were 1.0% and 2.0% (by weight) in subsurface sediments slurries (atrazine 30mg/L), and 2.0% in 1.5m pilot-scale sediment columns with groundwater flowing through (atrazine 0.08, desethylatrazine DEA 0.03, BAM 0.02μg/L). In the slurries under aerobic conditions, atrazine of 0...

Coupling of anaerobic ammonium oxidation (anammox) and denitrifying anaerobic methane oxidation (DAMO) microorganisms in a hollow-fiber membrane biofilm reactor (HfMBR) is a potential strategy for simultaneous anaerobic removal of nitrogen and methane in wastewater streams. In these systems, effluents contain dissolved organic substances from anammox and DAMO microorganisms, but their characteristics and relationships have not been investigated. In the present study, excitation-emission matrix (EEM) fluorescence spectroscopy was used to characterize effluent dissolved organic matter (EfDOM) from an Anammox-DAMO HfMBR...

Sudden unexpected death in epilepsy (SUDEP) is a major concern for patients with epilepsy. In most witnessed cases of SUDEP generalized seizures and respiratory failure preceded death, and pre-mortem neuroimaging studies in SUDEP patients observed changes in specific subcortical structures. Our study examined the role of subcortical structures in the DBA/1 mouse model of SUDEP using manganese-enhanced magnetic resonance imaging (MEMRI). These mice exhibit acoustically-evoked generalized seizures leading to seizure-induced respiratory arrest (S-IRA) that results in sudden death unless resuscitation is rapidly instituted...

Additional absorption was detected in absorption spectra within the range 300-350nm after addition of copper sulfate CuSO4(aq) to a solution of sodium salicylate NaНSal (рН=7.8). The additional maximum absorption was observed at 320nm. Assuming that the additional absorption depends on the formation of copper salicylate CuSal, the molar absorption coefficient εCuSal of this complex was determined to be (3.8±0.02)·10(3)М(-1)сm(-1). This value is almost equal to that of monoanion HSal(-), εHSal-=(3.6±0...
