Ni/NiO/Ni-B/graphene heterostructure-modified electrodes and their electrochemical activities towards acetaminophen.

The surface of graphene was decorated with nickel/nickel oxide/nickel-boron particles to develop high-performance electrochemical sensors. The nanohybrid structures were prepared via a one-step reduction method under an oxygen-rich atmosphere to obtain an oxide phase besides metallic nickel nanoparticles. In addition, the use of NaBH as the reducing agent enabled simultaneous formation of Ni-B species on the graphene surface.

Cytotoxic effect of 6-Shogaol in Imatinib sensitive and resistant K562 cells.

Chronic Myeloid Leukemia (CML) is a clonal hematopoietic malignancy characterized by the formation of BCR-ABL fusion protein. Imatinib (IMA) is a BCR-ABL tyrosine kinase inhibitor (TKI), which exhibited a high rate of response for newly diagnosed CML patients. Emergence of IMA resistance considered as a major challenge in CML therapy.

Thermodynamic modelling and optimization of oxy-reforming and oxy-steam reforming of biogas by RSM.

In this study, a comparative thermodynamic equilibrium calculation of biogas oxy-reforming and oxy-steam reforming processes to produce syngas has been conducted by Aspen Plus simulation software. The effects of temperature (600-800°C), pressure (1-20 atm), and inlet O/CH (0-1.0), HO/CH (0-3.

Sustained Adrenergic Signaling Promotes Intratumoral Innervation through BDNF Induction.

Mounting clinical and preclinical evidence supports a key role for sustained adrenergic signaling in the tumor microenvironment as a driver of tumor growth and progression. However, the mechanisms by which adrenergic neurotransmitters are delivered to the tumor microenvironment are not well understood. Here we present evidence for a feed-forward loop whereby adrenergic signaling leads to increased tumoral innervation.

Evaluation of the relationship between fungal infection, neutrophil leukocytes and macrophages in cervicovaginal smears: Light microscopic examination.

Background: Right after opportunistic fungi become pathogenic, they face immune system cells including macrophages and neutrophil leukocytes. Although the relationship between fungi and immune cells are being widely studied by using animal models and culture techniques, cervicovaginal smears have not been used to evaluate this interaction yet.

Aim: The aim of this study was to investigate the interactions between fungal infection, macrophages and neutrophil leukocytes in cervicovaginal smear.
