2D Ni-Co bimetallic oxide nanosheets activate persulfate for targeted conversion of bisphenol A in wastewater into polymers.

The selective removal of targeted pollutants from complex wastewater is challenging. Herein, a novel persulfate (PS)-based advanced oxidation system equipped with a series of two-dimensional (2D) bimetallic oxide nanosheets (NSs) catalysts is developed to selectively degrade bisphenol A (BPA) within mixed pollutants via initiating nonradical-induced polymerization. Results indicate that the NiCoO NSs demonstrate the highest catalytic efficiency among all Ni-Co NSs catalysts.

Caveolin-1 inhibits breast cancer stem cells via c-Myc-mediated metabolic reprogramming.

Breast cancer stem cells (BCSCs) are considered to be the root of breast cancer occurrence and progression. However, the characteristics and regulatory mechanisms of BCSCs metabolism have been poorly revealed, which hinders the development of metabolism-targeted treatment strategies for BCSCs elimination. Herein, we demonstrated that the downregulation of Caveolin-1 (Cav-1) usually occurred in BCSCs and was associated with a metabolic switch from mitochondrial respiration to aerobic glycolysis.

[Effect of Zirconium-Modified Zeolite Addition on Migration and Transformation of Phosphorus in River Sediments Under Static and Hydrodynamic Disturbance Conditions].

In this study, the effect of the addition of zirconium-modified zeolite (ZrMZ) on the migration and transformation of phosphorus (P) in river sediments under static and hydrodynamic disturbance conditions was studied using sediment core incubation experiments. Results showed that, whether under static or hydrodynamic disturbance condition, the ZrMZ amendment suppressed the release of SRP from sediments into the overlying water. Furthermore, the addition of ZrMZ to the upper sediment (0-10 mm) not only resulted in the decrease of the dissoluble reactive P (SRP) concentration in the overlying water at a depth of 0-30 mm, but also led to the decrease of the diffusion flux of SRP from the pore water to the overlying water across the sediment-water interface (SWI).

α-Lys Participates in Insertion of FeMoco to MoFe Protein and Maintains Nitrogenase Activity in M5al.

Our previous investigation of substrates reduction catalyzed by nitrogenase suggested that α-Ile of MoFe protein possibly functions as an electron transfer gate to Mo site of active center-"FeMoco". Amino acid residue α-Lys connects directly to α-Ile, and they are located in the same α-helix (α423-431). In the present study, function of α-Lys was investigated by replacing it with Arg (alkaline, like Lys), Gln (neutral), Glu (acidic), and Ala (neutral) through site-directed mutagenesis and homologous recombination.

Astragaloside IV enhances taxol chemosensitivity of breast cancer via caveolin-1-targeting oxidant damage.

Accumulating evidence suggests that caveolin-1 (CAV-1) is a stress-related oncotarget and closely correlated to chemoresistance. Targeting CAV-1 might be a promising strategy to improve chemosensitivity for breast cancer treatment. Astragaloside IV (AS-IV), a bioactive compound purified from Astragalus membranaceus, has been shown to exhibit multiple bioactivities, including anticancer.

Broadleaf Mahonia attenuates granulomatous lobular mastitis‑associated inflammation by inhibiting CCL‑5 expression in macrophages.

Granulomatous lobular mastitis (GLM) is a type of chronic mammary inflammation with unclear etiology. Currently systematic corticosteroids and methitrexate are considered as the main drugs for GLM treatment, but a high toxicity and risk of recurrence greatly limit their application. It is therefore an urgent requirement that safe and efficient natural drugs are found to improve the GLM prognosis.

[Research Progress of Supercontinuum Laser Spectroscopy in Biomedical Field].

Supercontinuum laser refers to the spectral broadening of an incident laser beam due to a series of nonlinear effects when the incident beam passes through a special light guide. With the development of ultrafast lasers and the photonic crystal fiber technology, the coherent and bright supercontinuum laser, generated with ultrashort pulses propagating in photonic crystal fibers, has become a kind of ideal white light source. Since supercontinuum lasers have been put into practice, their application domain is getting wider, especially for cells and bloods analysis in the biomedical field with fluorescence spectroscopy, flow cytometry, confocal microscopy, and optical coherence tomography as powerful analysis tools.

AMPK and Cancer.

This chapter focuses on the role of AMPK as a stress-response molecule with an emphasis on its duplex implication in carcinogenesis and cancer drug resistance. AMPK is closely correlated to the tumor-suppressive functions of LKB1 and P53, consequently modulating the activity of cellular survival signaling such as mTOR and Akt, leading to cell growth inhibition and cell cycle arrest. On the contrary, AMPK is tightly involved in cancer drug resistance via interacting with multiple known mechanisms of chemoresistance such as ABCG2 expression, autophagy induction, and cancer stem cells enrichment.

[Identification of Animal Whole Blood Based on Near Infrared Transmission Spectroscopy].

The inspection and classification for blood products are important but complicated in import-export ports or inspection and quarantine departments. For the inspection of whole blood products, open sampling can cause pollution and virulence factors in bloods samples may even endanger inspectors. Thus non-contact classification and identification methods for whole bloods of animals are needed.

The inflammasome: an emerging therapeutic oncotarget for cancer prevention.

Deregulated inflammation is considered to be one of the hallmarks of cancer initiation and development regulation. Emerging evidence indicates that the inflammasome plays a central role in regulating immune cells and cytokines related to cancer. The inflammasome is a multimeric complex consisting of Nod-like receptors (NLRs) and responds to a variety of endogenous (damage-associated molecular patterns) and exogenous (pathogen-associated molecular patterns) stimuli.

As a kind of spectroscopic technique, the remote laser-induced breakdown spectroscopy (Remote LIBS) can measure elemental compositions of remote targets by using high-power lasers and focusing approaches. In this paper, three remote detection approaches (open path LIBS, fiber optic LIBS and compact probe fiber optic LIBS) and their system architectures are summarized and analyzed. Conventional open path LIBS, with high requirement of specifications of lasers, optical systems, spectrographs and detectors, has always been a research focus in remote testing field.

Caveolin-1, a stress-related oncotarget, in drug resistance.

Caveolin-1 (Cav-1) is both a tumor suppressor and an oncoprotein. Cav-1 overexpression was frequently confirmed in advanced cancer stages and positively associated with ABC transporters, cancer stem cell populations, aerobic glycolysis activity and autophagy. Cav-1 was tied to various stresses including radiotherapy, fluid shear and oxidative stresses and ultraviolet exposure, and interacted with stress signals such as AMP-activated protein kinase.

Targeting AMPK Signaling Pathway to Overcome Drug Resistance for Cancer Therapy.

Mulitdrug resistance (MDR) is one of critical factorslimiting the efficacy of cancer chemoor radiotherapy. Emerging evidence has indicated that MDR is a complex process regulated by multiple factors, among which stress response molecules are considered as central players. AMP-activated protein kinase (AMPK) is a major regulator balancing energy supply and ultimately protects cells from harmful stresses via coordinating multiple metabolic pathways Notably, AMPK activation was recently shown to mediate the metabolism reprogramming in drug resistant cancer cells including promoting Warburg effects and mitochondrial biogenesis.

Caveolin-1 mediates chemoresistance in breast cancer stem cells via β-catenin/ABCG2 signaling pathway.

Accumulating evidence has suggested that cancer stem cells (CSCs) are at the root of drug resistance, and recent studies have indicated that caveolin-1, a membrane transporter protein, is involved in the regulation of cancer chemoresistance and stem cell signaling. However, the current understanding of the role of caveolin-1 in breast cancer development remains controversial. Herein, we demonstrate that caveolin-1 expression was upregulated after breast cancer chemotherapy in vitro and in vivo, accompanied by co-overexpression of β-catenin and ATP-binding cassette subfamily G member 2 (ABCG2) signaling.
