U. diffracta extract mitigates high fat diet and VD3-induced atherosclerosis and biochemical changes in the serum liver and aorta of rats

This study aims to investigate the antiatherogenic effects of the ethanol extract of U. diffracta and its mechanism.MethodA high fat diet and VD3 were used to establish the atherosclerotic rat model, with 0.004 g/kg/d of simvastatin as a positive control, fed with 0.7, 1.4, and 2.8 g/kg/d of Usnea ethanol extract for 21 days. The blood, liver, and aorta samples from each rat were collected after the last administration. Pharmacodynamic effects were evaluated. The inflammation related factors, the gene expressions of Toll-like receptor 5 (TLR5), myeloid differentiating factor 88 (MyD88), and nuclear factor-κB (NF-κB) were detected.Results and conclusionsCompared with the model group, simvastatin and ethanol extract of U. diffracta can significantly reduce the serum levels of triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), Ca2+, AST, ALT, the liver contents of total cholesterol (TC), TG, AI and liver index, as well as significantly increase the contents of high-density lipoprotein cholesterol (HDL-C) both in serum and liver (p

Cannabinoids may be useful in the management of rheumatic disorders for two broad reasons: their anti-inflammatory and immunomodulatory activity, and their ...

Authors: De Lima ACB, Brondízio E, Nardoto GB, Do Nascimento ACS Abstract Nutrition transition theory describes a progressive substitution of local staples for industrialized processed foods in local diets, a process documented diversely across world regions, and increasingly observed in rural areas of the global south. Here we examine the role of conditional cash transfer programs, in particular the emblematic Brazilian Bolsa Família (BFP), in driving nutritional transition in rural areas of the Amazon. Based on ethnographic research with both participating and nonparticipating women in the Aman&atil...

O'Sullivan, Eimear GallagherAbstractHigh levels of sucrose in foods present a great risk of obesity and type 2 diabetes. Therefore a low sucrose intake is strongly recommended. Sweet baked products incorporate high levels of sucrose. Sucrose in the original cake formulation was reduced and replaced with apple pomace, whey permeate, oligofructose, polydextrose. An acceptable sucrose reduction of between 21 and 27% was achieved. Cakes containing apple pomace had the ...

METHODS: We performed a randomized, single-center, single-blind study in 120 patients with established CAD. Patients were randomly assigned t...

We examined 9293 individuals from the Copenhagen General Population Study using nuclear magnetic resonance spectroscopy measurements of total cholesterol, free- and esterified cholesterol, triglycerides, phospholipids, and particle concentration. Fourteen subclasses of decreasing size and their lipid constituents were analysed: six subclasses were very low-density lipoprotein (VLDL), one intermediate-density lipoprotein (IDL), three low-density lipoprotein (LDL), and four subclasses were high-density lipoprotein (HDL). Remnant lipoproteins were VLDL and IDL combined. Mean nonfasting cholesterol concentration was 72...
