In this study, the humidity detection properties of ceramic with composition (Na0.5Bi0.5)0.94Ba0.06TiO3, noted (NBT-06BT), were investigated. The NBT-06BT was synthesized by semi-solid method and characterized X-ray diffraction (XRD) scanning electron microscopy (SEM). NBT-BT material sintered at 1100?C, crystallizes in tetragonal system without any secondary phase presents a heterogeneous dist...

Sodium–bismuth–titanate (NBT) has recently been shown to contain high levels of oxide ion conductivity. Here we report the effect A-site monovalent ions, M+ = K+ and Li+, on electrical conductivity NBT. The partial replacement Bi3+ with ions improved ionic by over one order magnitude without an apparent change conduction mechanism, which is attributed increase in oxygen vacancy concentration ba...

Chitin is a natural polymer found abundantly in the shells of crustaceans, insects and in fungi. Chitin and its deacetylated product chitosan are commercially manufactured from shells of shrimp and crab. Four experimental diets containing 0 (control), 10, 25 and 50 mg/kg chitin were prepared in the laboratory from a commercial pellet diet. A total of 50 rainbow trout were divided randomly into ...

The quassinoid analogue NBT-272 has been reported to inhibit MYC, thus warranting a further effort 7to better understand its preclinical properties in models of embryonal tumors (ET), a family of childhood malignancies sharing relevant biological and genetic features such as deregulated expression of MYC oncogenes. In our study, NBT-272 displayed a strong antiproliferative activity in vitro tha...

The most common X-linked recessive form of chronic granulomatous disease (X-CGD) is characterized by the absence of cytochrome b558 in neutrophils. In a rare variant form of X-CGD, cytochrome b558 is present but not functional. The gene (locus symbol CYBB) was localized to band Xp21 by studies of patients with small chromosome deletions. The gene was cloned based on its location and found to en...

The ability of highly purified human leukocytic pyrogen (LP) to stimulate neutrophil oxygen-dependent metabolism was studied. Human peripheral blood neutrophils exposed to leukocytic pyrogen in vitro demonstrated an increase in the percentage of neutrophils reducing nitroblue tetrazolium (NBT) dye and a marked stimulation of superoxide dismutase inhibitable reduction of ferricytochrome c. LP st...

Patients with sickle cell anaemia have an increased susceptibility to bacterial infections Previous reports of false-negative nitro blue tetrazolium (NBT) tests in the presence of bacteria infection and of a faulty phagocytic response following stimulation in vitro have suggested the possibility of polymorphonuclear dysfunction in certain patients with sickle cell anaemia. In the present study ...

Differentiation therapy by induction of tumor cells is an important method in the treatment of hematological cancers such as leukemia. Tumor cell differentiation ends cancer cells' immortality, thus stopping cell growth and proliferation. In our previous study, we found that fucose-containing polysaccharide fraction F3 extracted from Ganoderma lucidum can bring about cytokine secretion and cell...
