Mast cells and collagen fibrillogenesis.This article presents 20 combinations of histochemical stainings for the determination of mast cell co-localization with the fibrous component of the connective tissue in the fibrillogenesis course. Best results were obtained using metachromatic detection of mast cells in combination with silver or picro-fuchsin impregnation, staining with brilliant green using van Gieson staining, and a combination of aniline blue staining with neutral red. Proposed variants of histochemical protocols open up new opportunities to analyze the participation of mast cells in extracellular matrix remodeling of the tissue microenvironment in the course of adaptive and pathological processes. Results obtained expand the current theoretical views of the process of fibrillogenesis in the extracellular matrix. They also shed new light on the participation of mast cell secretion components in the molecular mechanisms of fiber formation.

Chloroplast avoidance movement: a novel paradigm of ROS signalling.The damaging effects of supra-optimal irradiance on plants, often turning to be lethal, may be circumvented by chloroplast avoidance movement which realigns chloroplasts to the anticlinal surfaces of cells (parallel to the incident light), essentially minimizing photon absorption. In angiosperms and many other groups of plants, chloroplast avoidance movement has been identified to be a strong blue light (BL)-dependent process being mediated by actin filaments wherein phototropins are identified as the photoreceptor involved. Studies through the last few decades have identified key molecular mechanisms involving Chloroplast Unusual Positioning 1 (CHUP1) protein and specific chloroplast-actin (cp-actin) filaments. However, the signal transduction pathway from strong BL absorption down to directional re-localization of chloroplasts by actin filaments is complex and ambiguous. Being the immediate cellular products of high irradiance absorption and having properties of remodelling actin as well as phototropin, reactive oxygen species (ROS) deemed to be more able and prompt than any other signalling agent in mediating chloroplast avoidance movement. Although ROS are presently being identified as fundamental component for regulating different plant processes ranging from growth, development and immunity, its role in avoidance movement have hardly been explored in depth. However, few recent reports have demonstrated the direct stimulatory involvement of ROS, especially HO, in chloroplast avoidance movement with Ca playing a pivotal role. With this perspective, the present review discusses the mechanisms of ROS-mediated chloroplast avoidance movement involving ROS-Ca-actin communication system and NADPH oxidase (NOX)-plasma membrane (PM) H-ATPase positive feed-forward loop. A possible working model is proposed.

Recent developments of nanoenzyme-based colorimetric sensors for heavy metal detection and the interaction mechanism.Heavy metal contamination has posed a great threat to human survival and social development. For this, a series of nanoenzyme-based colorimetric sensors, e.g., metal nanoparticles, metal oxides, metal sulfides, graphene-based nanomaterials, G-quadruplex and so on, were developed for the rapid and efficient detection of toxic heavy metal ions, whose detection limit for heavy metal ions could be as low as the nmol L-1 level. The recognition mechanism was based on the catalysis and signal amplification of nanozymes, a new type of nanomaterial possessing specific catalytic activity towards certain chemical reactions such as the oxidation of colorless TMB to blue oxTMB. In this work, we are trying to present readers with a better understanding of this important colorimetric sensing material by illustrating its application in the detection of heavy metal ions using metal nanoparticles, metal oxides, metal sulfides, graphene-based nanomaterials, G-quadruplex, etc. respectively.

Heterogeneous Fenton ferroferric oxide-reduced graphene oxide-based composite microjets for efficient organic dye degradation.A global water pollution on account of organic dye waste poses serious heath threat to human beings. Graphene-based micromotors have recently attracted considerable attentions for efficient water remediation. However, a secondary catalytic degradation is required for completely destroying persistent organic dyes after their adsorption by graphene and its derivatives. Here, we immobilized ferroferric oxide (FeO) nanoparticles (NPs) with reduced graphene oxide (rGO)-based micromotors in order to synthesize heterogeneous Fenton FeO-rGO/Pt composite microjets and to improve their catalytic performance. The as-prepared composite microjets are well propelled in contaminated waters by Pt catalyzing hydrogen peroxide. Combining the attractive properties of reduced graphene oxide (rGO) and FeO NPs along with fascinating motor movement, the composite microjets offer an efficient removal of methylene blue in short time. This outstanding catalytic performance is ascribed to the synergistic effect of FeO and rGO during the heterogeneous Fenton-like reaction and the enhanced localized mixing effect during the motion. Moreover, the Fenton composite microjets are able to magnetically recovered and reused for further decontamination processes. Our proposed Fenton composite microjets with extraordinary catalytic capability and good recyclability holds considerable promise for diverse environmental applications.

Removal of methylene blue dye using rice husk, cow dung and sludge biochar: Characterization, application, and kinetic studies.The present studies aimed for the removal of Methylene blue (MB) dye using the rice husk biochar (RHB), cow dung biochar (CDB) and domestic sludge biochar (SB) synthesized through slow pyrolysis at 500 °C. The biochar was used for the adsorption of synthetic aqueous MB dye. The removal efficiencies of MB by CDB, RHB and SB in a batch experiment were 97.0-99.0; 71.0-99.0 and 73.0-98.9% at conditions, pH (2.0-11.0); Biochar dosage (0.5-6.0 g/100 mL) for 5 days. Adsorption isotherm of Langmuir constant (K) were obtained 0.101, 0.583 and 0.128 for RHB, CDB and SB respectively. Further, adsorption kinetics of pseudo first order for RHB, CDB and SB were 0.068, 0.018, and 0.066 while it was 0.031, 0.023 and 0.273 for pseudo second order kinetics. Thus, CDB was more effective adsorbent for the dye removal. The pHz values were 7.8, 6.3 and 6.0 for the CDB, RHB, and SB, respectively.

Photoelectric effect driving PANI/PB multicolor visualized detection of CEA based on AgS [email protected] NTs.In this work, a multicolor visual immunoassay platform was developed. The photoelectric effects of AgS [email protected] NTs made the color changes of PANI/PB, which enabled visual inspection of CEA. Under the visible light excitation, AgS [email protected] NTs generates electron-holes. Where, photoelectrons will pass electrical circuit to PB and photoinduced holes will oxidize PANI, which making the PANI/PB composite changes from emerald green-blue-purple-black colors. When CEA was incubated, the migration rate of photogenerated carriers is slowed down owing to the steric hindrance, resulting in different color changes of PANI/PB. In addition, the average green channel of PANI/PB read by photoshop has a certain correlated linear relationship with the concentration of CEA. Meanwhile, we can observe the color transformation of PANI/PB with our own eyes. By integrating advantages of photoelectrochemistry and colorimetry, the linear range of CEA detection was 0.1-20 ng/mL, and the detection limit was 0.05 ng/mL (S/N = 3). More importantly, this multicolor sensing method is very convenient, simple and low-cost. The photocarriers-modulated colorimetric strategy also provides a novel idea for visual portable platform design in clinical diagnosis.

Self-reported physical and psychological symptoms among victims and perpetrators of Arab American adolescents.The adverse effects of bullying victimization among adolescents have been examined extensively. However, few studies have examined how bullying perpetration affects health. Moreover, ethnic or religious minorities are particularly at risk for bullying involvement, but little is known about bullying among Arab Americans. The purpose of this study is to examine how bullying perpetration and victimization are related-independently and concurrently-to physical and psychological problems among Arab American adolescents.

Rapid determination of carbapenem resistance by low-cost colorimetric methods: Propidium Iodide and alamar blue staining.Carbapenems are a class of β-lactam antibiotics with a broad antimicrobial activity spectrum. Owing to their sturdy structures resistant to most β-lactamases, they have been regarded as one of the last-resort antibiotics for combating multidrug-resistant bacterial infections. However, the emergence of carbapenem resistance increases predominantly in nosocomial pathogens. To prevent spread of carbapenem resistance in early stages, it is imperative to develop rapid diagnostic tests that will substantially reduce the time and cost in determining carbapenem resistance. Thus, we devised a staining-based diagnostic method applicable to three different Gram-negative pathogens of Acinetobacter baumannii, Escherichia coli, and Klebsiella pneumoniae, all with the high potential to develop carbapenem resistance. Regardless of the resistance mechanisms presented by bacterial species and strains, double staining with propidium iodide (PI) and alamar blue (AB) identified resistant bacteria with an average sensitivity of 95.35%, 7 h after imipenem treatments in 343 clinical isolates. Among the three species tested, A. baumannii showed the highest diagnostic sensitivity of 98.46%. The PI and AB-mediated staining method could be a promising diagnostic method with high-throughput efficacy and low cost.
