Effect of washing, soaking, and cooking methods on perfluorinated compounds in mackerel ().

Perfluorinated compounds (PFCs) are environmental pollutants, and dietary intake is a major route of human exposure to them. We aimed to see the effects of washing, soaking, and cooking (grilling, braising, frying, and steaming) on the change of PFCs in mackerel fillets and PFCs before and after each treatment were analyzed using LC-MS/MS. Washing resulted in a decrease in the PFC content of mackerel (average 74%) comparing to control.

Parabens in breast milk and possible sources of exposure among lactating women in Korea.

Parabens, broad-spectrum antimicrobial preservatives widely used in various consumer products and food, are suspected to be linked with several adverse health effects in humans, especially newborn babies, infants, and young children. While human exposure to parabens has been frequently reported by measuring the concentration of parabens in urine, similar measurements in breast milk have rarely been made. To determine paraben concentrations in breast milk and possible sources of exposure, four major parabens, including methylparaben (MP), ethylparaben (EP), propylparaben (PP), and butylparaben (BP) were measured in breast milk samples collected from 260 lactating women in South Korea.

The protective effects of Blume extracts on middle cerebral artery occlusion in rats.

To investigate the effects of Blume (GEB) and 4-hydroxybenzyl alcohol (HBA) on brain damage, GEB or HBA was administered orally for 14 days before middle cerebral artery occlusion (MCAO). After 24 h reperfusion, the proportion of circling was significantly reduced in the GEB (79%) or HBA (69%) group compared to the MCAO group (100%) in the corner test, and the removal time in the adhesive removal test was significantly decreased in the GEB (117 ± 21.0 s) and HBA (101 ± 20.

Protective effects of on acetaminophen-induced liver and kidney toxicity in rats.

An overdose of acetaminophen (AAP) causes hepatic and renal toxicity. This study examined the protective effects of (GEB) on hepatic and renal injury induced by AAP. Rats were orally administered distilled water or GEB for 14 days and injected with AAP 1 h after the oral last administration; control rats were administered water without AAP injection.

Antioxidant Activities of Functional Beverage Concentrates Containing Herbal Medicine Extracts.

This study investigated the antioxidant activity of functional beverage concentrates containing herbal medicine extracts (FBCH) using various antioxidant assays, such as 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging activity, and reducing power assay. The total polyphenolic content of FBCH (81.45 mg/100 g) was higher than Ssanghwa tea (SHT, 37.

Molecular cloning and characterization of a bile salt hydrolase from Lactobacillus acidophilus PF01.

Phenotypic screening for bile salt hydrolase (BSH) activity was performed on Lactobacillus acidophilus PF01 isolated from piglet feces. A gene encoding BSH was identified and cloned from the genomic library of L. acidophilus PF01.
