silica/obesity

BACKGROUND There is a need for medical treatments to curb the rising rate of obesity. Weight reduction is correlated with a decrease in associated risk factors and cholesterol levels in humans. Amorphous silica particles have been found to exert a hypocholesterolemic effect in humans, making them

OBJECTIVE To establish a TLC-FTIR method for detection of western medicine phenolphthalein added illegally into anti-obesity and healthcare food. METHODS The sample was extracted with anhydrous alcohol. The stationary phase was the GF254 aluminium alloy silica gel plates (10 cm x 20 cm) while the

The early, predictable, onset of spontaneous autoimmune thyroiditis (SAT) in Obese strain (OS) chickens provides a unique opportunity to analyse the mechanisms initiating autoimmunity which is virtually impossible to obtain in humans. In this study we focused on the respective roles of viruses and

Spleen cells from non-obese diabetic mice were found to generate low interleukin 2 production and cell proliferation in response to concanavalin A. However, some of non-obese diabetic mice maintained in the same environment preserved their responsiveness to this T cell mitogen. Non-obese diabetic

Many types of biocompatible nanomaterials have proven of low cytotoxicity and hold great promise for various applications in nanomedicine. Whereas they generally do not cause apparent organ toxicity or tissue damage in adult animals, it is yet to determine their biological consequences in more

The disturbed homeostasis of the immune system in Obese strain (OS) chickens with spontaneous autoimmune thyroiditis consists in a general T cell hyperreactivity (concanavalin A hyperresponsiveness, interleukin 2 (IL 2) hypersecretion), particularly expressed by those lymphocytes which infiltrate

The cytotoxicity of macrophages from non-obese diabetic (NOD) mice against murine mastocytoma (P-815), and murine beta-cell lines having the NOD gene background (MIN6N-9a), were examined. Peritoneal exudate cells from 20-week-old mice showed higher cytotoxicity, measured as inhibition of thymidine

We investigate the role played by dendritic cells (DCs) in the non-obese diabetic (NOD) mouse pancreas. The early peri-islet, nondestructive infiltration phase, and intra-islet, destructive infiltration phase, which immediately precedes overt diabetes, are studied. Results show that infiltrating

The quantity of the main lipid classes in hepatic tissue has been determined via thin layer chromatography on silica gel, the tissue obtained by blind hepatic biopsy in 20 patients with diabetes mellitus and obesity and in a control group of 5 patients with no hepatic disease. A considerable

Background: Precisely engineered mesoporous silica has been shown to induce weight loss in mice, but whether it is safe to use in humans have not investigated. Objective: The

Nanoparticles are of great interest due to their wide variety of biomedical and bioengineering applications. However, they affect cellular differentiation and/or intracellular signaling when applied and exposed to target organisms or cells. The brown adipocyte is a cell type important in energy

Aim: Obesity is a risk factor for cardiovascular disease and diabetes. We aimed to elucidate the effects of distinct mesoporous silica particles (MSPs) supplemented in food on metabolic parameters in obesity. Materials & methods: MSPs with precisely controlled pore size were

Engineered mesoporous silica particles (MSP) are thermally and chemically stable porous materials composed of pure silica and have attracted attention for their potential biomedical applications. Oral intake of engineered MSP is shown to reduce body weight and adipose tissue in mice. Here, clinical

OBJECTIVE Occupational exposure to silica dust is associated with significant impairment of lung function. The present study investigates which pathological changes in the lung are associated with impairment of lung function in silica dust exposed workers who were life-long non-smokers. METHODS 242
