this paper reports on synthesis of a magnetic adsorbent for wastewater treatment purposes. in this regard, platanus orientalis waste leaves were chosen as a cheap material for preparing the magnetic adsorbent by loading magnetite nanoparticles on it. the synthesized adsorbent was characterized using scanning electron microscope and x-ray diffractometer. then, it was used for magnetic solid phas...

mark-release-recapture methods are used for delineating foraging territories of termite colonies and estimating their foraging populations. in this research, marking of termites was evaluated by the use of two ingested dyes: nile blue (nb) and neutral red (nr). in this experiment, filter paper circles were wetted with 1 ml of each dye at concentrations of 0.1%, 0.25% and 0.5% (treatments) and p...

Previous studies have shown that intensive macropinocytosis occurs in cancer cells and neutral red (NR) is noted for its capability to enter into the cell massively through a process mimetic to macropinocytosis. In addition, trans-cinnamic acid (tCA) has been found to be an inhibitor of histone deacetylase (HDAC). In the present study, cinnamoylphenazine (CA-PZ) that consists of NR and tCA moie...

BACKGROUND Ovarian tissue cryopreservation, in combination with autotransplantation or long-term culture, has been proposed as a means of fertility preservation. However follicle density within ovarian cortex has a profound impact on the success of in vivo and in vitro systems designed to support follicle growth and restore fertility. The objective of this study was to investigate the dye neutr...

Background. It is unclear whether the clinical use of tibial rotation to measure the strength of the medial hamstrings and lateral hamstrings in isolation is based on sound scientific evidence or is simply based on anatomical features. Objectives. To verify the appropriateness of tibial rotation for isolation of the medial hamstrings and lateral hamstrings, the participants performed neutral r...

Cytotoxicity assays using cell cultures may be an alternative to assess biological toxicity of plant extracts with potential phytotherapeutic properties. This study compared three methods to prepare culture media for the exposure of Vero cells to plant extracts. Leaves of Glandularia selloi (Spreng.) Tronc. were used to prepare culture medium with aqueous extract, extract in culture medium and ...

−The effects of electrochemical reducing power on enrichment, growth, and ammonium production of freeliving diazotrophs from rhizosphere soil were evaluated. Soil bacteria were cultivated in a conventional bioreactor (CBR) and an electrochemical bioreactor (EBR), both containing a neutral red-modified graphite felt (NR-GF) cathode and a platinum anode, but with electricity charged to the EBR on...

Electrically reduced neutral red (NR) served as the sole source of reducing power for growth and metabolism of pure and mixed cultures of H2-consuming bacteria in a novel electrochemical bioreactor system. NR was continuously reduced by the cathodic potential (-1.5 V) generated from an electric current (0.3 to 1.0 mA), and it was subsequently oxidized by Actinobacillus succinogenes or by mixed ...

L. lactis sk071115 has been shown to grow more actively and generate lower levels of lactate in glucose-defined medium with nitrate than in medium with Mn(IV). By adding Mn(IV) to a L. lactis culture, lactate production was relatively reduced in combination with Mn(II) production, but cell mass production levels did not increase. Both cell-free extract and intact L. lactis cells reacted electro...
