the aim to achieve in this study is to recover the cr(iii) and process waters used in thewastewaters of chrome tanning operation by membrane process during leather production. in the treatmentalternative contains, cartridge filter, nanofiltration (nf(np10)), nanofiltration nf(xn45) and reverse osmosisro(acm2) membranes. the raw chrome wastewater from the cartridge filter was given to nf(np10)me...

The CCAAT box is one of the most common cis-elements present in eukaryotic promoters and is bound by the transcription factor NUCLEAR FACTOR Y (NF-Y). NF-Y is composed of three subunits, NF-YA, NF-YB, and NF-YC. Unlike animals and fungi, plants have significantly expanded the number of genes encoding NF-Y subunits. We provide a comprehensive classification of NF-Y genes, with a separation of cl...

PG490 (triptolide) is a diterpene triepoxide with potent immunosuppressive and antiinflammatory properties. PG490 inhibits interleukin(IL)-2 expression by normal human peripheral blood lymphocytes stimulated with phorbol 12-myristate 13-acetate (PMA) and antibody to CD3 (IC50 of 10 ng/ml), and with PMA and ionomycin (Iono, IC50 of 40 ng/ml). In Jurkat T-cells, PG490 inhibits PMA/Iono-stimulated...

Paracetamol (known as acetaminophen, or APAP) poisoning causes acute liver damage that can lead to organ failure and death. We sought determine APAP overdose augment tumor necrosis factor-alpha (TNF-α)/ nuclear factor kappa B (NF-kB)/induced nitic oxide synthase (iNOS) axis-mediated hepatotoxicity in rats, the anti-inflammatory polyphenolic compounds, quercetin (QUR) plus resveratrol (RES) ame...

Developing oxygen evolution reaction (OER) electrocatalysts is essential to accomplish viable CO2 and water electrolysis. Herein, we report the fabrication OER performance of Ni-foam (NF)-immobilized Ni6 nanoclusters (NCs) (Ni6/NF) prepared by a dip-coating process. The Ni6/NF electrode exhibited high current density 500 mA/cm<sup>2</sup> for at an overpotential as low 0.39 V. durab...

Neurofilaments (NFs) are prominent components of large myelinated axons. Previous studies have suggested that NF number as well as the phosphorylation state of the COOH-terminal tail of the heavy neurofilament (NF-H) subunit are major determinants of axonal caliber. We created NF-H knockout mice to assess the contribution of NF-H to the development of axon size as well as its effect on the amou...

Stimulation of T lymphocytes through their antigen receptor leads to the appearance of several transcription factors, including NF-AT and NF-kappa B, which are involved in regulating genes required for immunologic activation. To investigate the activity of a single transcription factor in individual viable cells, we have applied an assay that uses the fluorescence-activated cell sorter to quant...

fuel cells, secondary batteries and capacitors are among many promising energy storage devices. in particular, supercapacitors have attracted much attention because of their long life cycle and high power density. graphene/nickel ferrite(g-nf) based supercapacitors were successfully fabricated through a one-step facile solvothermal route. effects of synthesis conditions i.e. solvothermal time a...

background: leishmania major is an intracellular parasite transmitted through the bite of the female phlebotomine sand flies. leishmania major is able to escape the host immune defense and survive within macrophages. modulation of the nf-κb (nuclear factor-kappa b) activation and suppression of the pro-inflammatory cytokines by l. major are the main evasion mechanisms that remain to be explored...

NF of activated T cells (NF-AT) denotes a family of transcription factors that regulate the activation-dependent expression of many immunologically important proteins. At least four distinct genes encode the various family members, and several isoforms of these have been identified as well. The overlapping expression patterns and similar in vitro binding and trans-activation activities on vario...
