Evaluation of mercury, lead, and cadmium in the waste material of crevalle jack fish from the Gulf of Urabá, Colombian Caribbean, as a possible raw material in the production of sub-products.

The Gulf of Urabá, currently considered a national strategic ecoregion, could be threatened by the presence of heavy metals such as mercury (Hg), lead (Pb), and cadmium (Cd), which directly affect the aquatic ecosystem. In Colombia, investigations on marine species pollution are scarce; however, their products are consumed. The aim of this study was to quantify the contents of Hg, Pb, and Cd in muscle and in waste material (head-gills, viscera, fins-tail), in one of one of the most commercialized resources, the crevalle jack (Caranx hippos), and to determine their presence in some of the body portions that are used in the production of sub-products.

BACE1 RNAi Restores the Composition of Phosphatidylethanolamine-Derivates Related to Memory Improvement in Aged 3xTg-AD Mice.

β-amyloid (Aβ) is produced by the β-secretase 1 (BACE1)-mediated enzymatic cleavage of the amyloid precursor protein through the amyloidogenic pathway, making BACE1 a therapeutic target against Alzheimer's disease (AD). Alterations in lipid metabolism are a risk factor for AD by an unknown mechanism. The objective of this study was to determine the effect of RNA interference against BACE1 (shBACEmiR) on the phospholipid profile in hippocampal CA1 area in aged 3xTg-AD mice after 6 and 12 months of treatment compared to aged PS1KI mice.

Coffee Consumption Increases the Antioxidant Capacity of Plasma and Has No Effect on the Lipid Profile or Vascular Function in Healthy Adults in a Randomized Controlled Trial.

Background: Coffee, a source of antioxidants, has controversial effects on cardiovascular health.

Objective: We evaluated the bioavailability of chlorogenic acids (CGAs) in 2 coffees and the effects of their consumption on the plasma antioxidant capacity (AC), the serum lipid profile, and the vascular function in healthy adults.

Methods: Thirty-eight men and 37 women with a mean ± SD age of 38.
