Changes of IgA+ cells and cytokines in the cecal tonsil of broilers fed on diets supplemented with vanadium.
The cecal tonsil of broiler is known as a secondary lymphoid tissue, which is involved in antigen-specific humoral immune responses. The purpose of this study was to investigate the effects of dietary...Read More
The purpose of this 42-day study was to investigate the apoptosis in the bursa of Fabricius induced by different levels of dietary vanadium. A total of 420 1-day-old avian broilers were divided into 6...Read More
The purpose of this study was to examine oxidative stress induced by dietary vanadium in the mucosa of different parts of intestine including duodenum, jejunum, ileum, and cecal tonsil. A total of 420...Read More
We're sorry this abstract is currently not available....Read More
Recent studies demonstrated the carcinogenicity and the mutagenicity of vanadium compounds. In addition, vanadium (V^5^+) was found to enhance the effects of other genotoxic agents. However, the mecha...Read More
The effects of ammonium metavanadate on biochemical, hormonal, haematological and histopathological parameters of the female Wistar rats.
The effects of different doses of ammonium metavanadate on the biochemical, haematological, hormonal and histopathological parameters of stilbesterol treated female Wistar rats were investigated. Ammo...Read More
Transcriptional and posttranscriptional regulation of CYP1A1 by vanadium in human hepatoma HepG2 cells.
We recently demonstrated that V(5+) downregulates 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)-mediated induction of Cyp1a1 mRNA, protein, and catalytic activity levels in Hepa 1c1c7 cells through trans...Read More
Contrasting Synergistic Anion Effects in Vanadium(V) Binding to Nicatransferrin versus Human Serum Transferrin.
Some ascidians sequester vanadium and other metal ions that are bound and transported in higher organisms by transferrin. The ascidian Ciona intestinalis has a monolobal transferrin (nicatransferrin) ...Read More
Carcinogen-induced early molecular events and its implication in the initiation of chemical hepatocarcinogenesis in rats: Chemopreventive role of vanadium on this process
Carcinogen-induced formation of DNA adducts and other types of DNA lesions are the critical molecular events in the initiation of chemical carcinogenesis and modulation of such events by chemopreventi...Read More
Transitional metals, as vanadium, are known to exert noxious effects by generating oxidative stress. Addition of antioxidants in the diet could decrease the cytotoxic effect related to the oxidative s...Read More
Pentavalent vanadium induces hepatic metallothionein through interleukin-6-dependent and -independent mechanisms
Metallothionein (MT) is a low-molecular-weight cysteine-rich protein which has a high affinity for metals. The synthesis of MT is induced by heavy metals such as cadmium and zinc. However, little is k...Read More
Molecular basis of anticlastogenic potential of vanadium in vivo during the early stages of diethylnitrosamine-induced hepatocarcinogenesis in rats.
Carcinogen-induced DNA base modification and subsequent DNA lesions are the critical events for the expression of premalignant phenotype of the cell. We have therefore investigated the chemopreventive...Read More
Sensitive spectrophotometric methods for quantitative determination of chlorprothixene in pharmaceutical dosage form.
Simple and sensitive UV-VIS spectrophotometric methods for the determination of chlorprothixene hydrochloride have been developed. One of them is based on the oxidation of chlorprothixene (CPT) by amm...Read More
Evaluation of changes in the element content and biomass of invaded with Meloidogyne arenaria Tiny Tim tomato plants under NH4VO3 treatment.
The parasite-host system Meloidogyne arenaria--Tiny Tim tomato plants has been studied in order to investigate the influence of the process of invasion on the chemical composition and biomass of plant...Read More
Improved selective, simple, and contrast staining of acidophilic neurons with vanadium acid fuchsin.
Acidophilia is one of the hallmarks of acute neuronal damage and death in brain ischemia, excitotoxic and traumatic lesions and epileptic seizures. We here describe a novel and simple method for visua...Read More
Vanadium and its derivatives are the well-known environmental pollutants. We obtained that ammonium vanadate suppressed the alkaline (AlP) and acid (AcP) phosphatases activity in the variety of tissue...Read More
Female reproduction alterations induced by vanadium salts, taken in periods no related with mating/gestation, correlated with histological alterations has not been reported. Vanadium is a metal from V...Read More
