To determine the role of nitric oxide (NO) in rat liver transporter regulation, we investigated in precision-cut liver slices the effect of NO and peroxynitrite (ONOO(-)), a reaction product of NO with superoxide (O(2(-))), on mRNA levels of 13 influx and efflux transporters. To inactivate Kupffer cells (KCs), liver slices were prepared from rats treated with gadolinium chloride (Gd). Transport...

Neovascularization is a limiting factor in tumor growth and progression. It is well known that changes in the tumormicroenvironment, such as hypoxia and glucose deprivation (GD), can induce VEGF production. However, the mechanism linking GD to tumor growth and angiogenesis is unclear. We hypothesize that GD induces the angiogenic switch in tumors through activation of the unfolded protein respo...

Recent data have shown that cardioprotection can result in the import of specific proteins into the mitochondria in a process that involves heat shock protein 90 (HSP90) and is blocked by geldanamycin (GD), a HSP90 inhibitor. To test the hypothesis that an alteration in mitochondrial import is a more widespread feature of cardioprotection, in this study, we used a broad-based proteomics approac...

Treatment of high-risk neuroblastoma (NB) represents a major challenge in paediatric oncology. Alternative therapeutic strategies include antibodies targeting the disialoganglioside GD(2) , which is expressed at high levels on NB cells, and infusion of donor-derived natural killer (NK) cells. To combine specific antibody-mediated recognition of NB cells with the potent cytotoxic activity of NK ...

Respiratory distress syndrome (RDS) and bronchopulmonary dysplasia remain the leading causes of preterm infant morbidity, mortality, and lifelong disability. Research to improve outcomes requires translational large animal models for RDS. Preterm pigs delivered by caesarian section at gestation days (GD) 98, 100, 102, and 104 were provided 24 h of neonatal intensive care, monitoring (pulse oxim...

Aflatoxin B1 (AFB1) is the most toxic and common among major types of aflatoxins. AFB1 hepatoxic has been implicated in an increase risk hepatocellular carcinoma, also effect AFs on brain chemistry have documented. Probiotics health benefits provide powerful for body brain. The present study was designed to reveal efficiency Bacillus subtilis NS4182-01 against hematological, biochemical histopa...

GlycodelinA (GdA), a multifunctional glycoprotein secreted at high concentrations by the uterine endometrium during the early phases of pregnancy, carries glycan chains on asparagines at positions N28 and N63. GdA purified from amniotic fluid is known to be a suppressor of T-cell proliferation, an inducer of T-cell apoptosis, and an inhibitor of sperm-zona binding in contrast to its glycoform, ...

background: the monoclonal antibody, c595, against breast cancer cell line was conjugated with cyclic anhydride gadolinium-diethylenetriaminepenta-acetic acid (gd-cdtpaa) to produce gd-dtpa-c595 and used as specific breast cancer cell line (mcf-7) contrast agents in magnetic resonance imaging (mri).  methods: after incubation of breast cancer cell line (mcf-7), with different contrast agents (g...

BACKGROUND Graves' orbitopathy (GO) is an autoimmune inflammatory ocular complication and one of the most frequent manifestations of Graves' disease (GD). Clinical judgment of GO is subjective sometimes leading to clinical and therapeutic challenges. Better tools to diagnose this severe complication are warranted. PATIENTS AND METHODS The aim of the present study was to evaluate tear levels o...

BACKGROUND Gaucher disease (GD) is the most common inherited lysosomal storage disorder in humans, caused by mutations in the gene encoding the lysosomal enzyme glucocerebrosidase (GBA1). GD is clinically heterogeneous and although the type of GBA1 mutation plays a role in determining the type of GD, it does not explain the clinical variability seen among patients. Cumulative evidence from rece...
