Selective contrast agents with potential to the earlier detection of tumors: Insights on synthetic pathways, physicochemical properties and performance in MRI assays.

Numai utilizatorii înregistrați pot traduce articole

Magnetic iron oxide nanoparticles (MNPs) have been prepared and stabilized with three organic acids (tartaric, malic and ascorbic) in order to obtain biocompatible and water dispersible MNPs with potential to bind specifically to tumoral cancer cells. An in deep characterization was performed aiming

Discovery of estrogen receptor α modulators from natural compounds in Si-Wu-Tang series decoctions using estrogen-responsive MCF-7 breast cancer cells.

Numai utilizatorii înregistrați pot traduce articole

The binding between the estrogen receptor α (ER-α) and a variety of compounds in traditional Chinese formulae, Si-Wu-Tang (SWT) series decoctions, was studied using a stably-transfected human breast cancer cell line (MVLN). In 38 compounds tested from SWT series decoctions, the estrogen-like

Cytotoxicity of aniline mustard glucuronide alone or in a combination with glucose in Walker cells in culture and sarcoma-180 tumour bearing animals.

Numai utilizatorii înregistrați pot traduce articole

The effect of aniline mustard glucuronide (AMG), p-hydroxyaniline mustard (HAM), and aniline mustard (AM), on Walker ascites tumour cells in vitro showed that AM in about 80 times more toxic than its glucuronide but HAM is at least 800 times more toxic. A non toxic dose of AMG became completely

Immune modulatory potentials of antineoplaston A-10 in breast cancer patients.

Numai utilizatorii înregistrați pot traduce articole

Antineoplastons are naturally occurring cytodifferentiating agents. Chemically, they are medium and small sized peptides, amino acid derivatives and organic acids, which exist in blood, tissues and urine. Antineoplaston A-10 (3-phenylacetylamino-2,6-piperidinedione) is the first chemically

Correlation between liver cancer occurrence and gene expression profiles in rat liver tissue.

Numai utilizatorii înregistrați pot traduce articole

Liver cancer (LC) is generally characterized by malignant cell proliferation and growth; it normally develops in stages that progress from non-specific injury of the liver to liver fibrosis, liver cirrhosis, dysplasia nodules, and liver carcinoma. We used a rat model of diethylnitrosamine

Consumption of vitamin B(6) reduces fecal ratio of lithocholic acid to deoxycholic acid, a risk factor for colon cancer, in rats fed a high-fat diet.

Numai utilizatorii înregistrați pot traduce articole

To examine the effect of supplemental dietary vitamin B(6) on the colonic luminal environment, growing male rats were fed a high-fat diet containing 1, 7, or 35 mg pyridoxine HCl/kg diet for 6 wk. Food intake and growth were unaffected by the dietary treatment. Supplemental dietary vitamin B(6)

Cecal succinate elevated by some dietary polyphenols may inhibit colon cancer cell proliferation and angiogenesis.

Numai utilizatorii înregistrați pot traduce articole

This study demonstrated that 0.5% dietary rutin, ellagic acid, or curcumin markedly increased cecal succinate levels in rats fed a high-fat diet, whereas catechin, caffeic acid, and quercetin did not. Other organic acids were modestly or hardly affected by polyphenols. To clarify the effects of

Organic acid component from Taraxacum mongolicum Hand.-Mazz alleviates inflammatory injury in lipopolysaccharide-induced acute tracheobronchitis of ICR mice through TLR4/NF-κB signaling pathway.

Numai utilizatorii înregistrați pot traduce articole

Inflammation plays an important role in the pathogenesis of acute tracheobronchitis. Taraxacum mongolicum Hand.-Mazz (TMHM) is a dietic herb for heat-clearing and detoxifying functions as well as swell-reducing and mass-resolving effect in Traditional Chinese Medicine. Studies have shown that its

Enantioselective Effects of Metalaxyl Enantiomers on Breast Cancer Cells Metabolic Profiling Using HPLC-QTOF-Based Metabolomics.

Numai utilizatorii înregistrați pot traduce articole

In this study, an integrative high-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry (HPLC-QTOF) based metabolomics approach was performed to evaluate the enantioselective metabolic perturbations in MCF-7 cells after treatment with R-metalaxyl and

Metabonomic Profiling Reveals Cancer Chemopreventive Effects of American Ginseng on Colon Carcinogenesis in Apc(Min/+) Mice.

Numai utilizatorii înregistrați pot traduce articole

American ginseng (Panax quinquefolius L.) is one of the most commonly used herbal medicines in the West. It has been reported to possess significant antitumor effects that inhibit the process of carcinogenesis. However, the mechanisms underlying its anticancer effects remain largely unresolved. In

Infusion and decoction of wild German chamomile: bioactivity and characterization of organic acids and phenolic compounds.

Numai utilizatorii înregistrați pot traduce articole

Natural products represent a rich source of biologically active compounds and are an example of molecular diversity, with recognised potential in drug discovery. Herein, the methanol extract of Matricaria recutita L. (German chamomile) and its decoction and infusion (the most consumed preparations

2-Naphthoic acid ergosterol ester, an ergosterol derivative, exhibits anti-tumor activity by promoting apoptosis and inhibiting angiogenesis.

Numai utilizatorii înregistrați pot traduce articole

Phytosterol is a natural component of vegetable oil and includes ergosterol (ER) and β-sitosterol. In this study, three new ergosterol monoester derivatives were obtained from the reflux reaction with ergosterol, organic acids (furoic acid, salicylic acid, and 2-naphthoic acid), EDCI, and DMAP in

Numai utilizatorii înregistrați pot traduce articole

The study of metabolomics in natural products using the diverse analytical instruments including GC-MS, LC-MS, and NMR is useful for the exploration of physiological and biological effects and the investigation of drug discovery and health functional foods. Cordyceps militaris has been very

Decellularized Lymph Node Scaffolding as a Carrier for Dendritic Cells to Induce Anti-Tumor Immunity.

Numai utilizatorii înregistrați pot traduce articole

In recent decades, the decellularized extracellular matrix (ECM) has shown potential as a promising scaffold for tissue regeneration. In this study, an organic acid decellularized lymph node (dLN) was developed as a carrier for dendritic cells (DCs) to induce antitumor immunity. The dLNs were
