The study is the first to aim at determining the protective effect of cannabidiol (CBD) against oxidative stress and inflammation induced by toxic metal exposure in Transformed Human Liver Epithelial-2 (THLE-2) cell lines representing healthy liver cells.

A mechanistic review of pharmacological activities of homeopathic medicine licorice against neural diseases.

The use of medicinal plants has grown in popularity in recent decades because, as natural ingredients, they have fewer adverse effects and are more effective than synthetic alternatives. As a small perennial herb, L. (Licorice) has been investigated for its therapeutic efficacy against neural disorders mainly ischemic stroke as well as the neurodegenerative diseases such as dementia and Alzheimer's disease, and Parkinson's disease which has been attributed to its HMGB inhibitory function, reactive oxygen scavenging and anti-inflammatory activity.

Introduction: The etiology/pathophysiology of preeclampsia remains an enigma. Maternal inflammation (humoral and cellular) is a key factor in the etiology of late-onset preeclampsia (L-PrE). Presepsin is split out from the phagocytes membranes after phagocytosis.

Simultaneous quantitative detection of 10 phthalates in PVC children's toys by HPLC-PDA.

A high-performance chromatography-photodiode array detection (HPLC-PAD) method has been developed and validated for the identification and quantification of ten phthalates; diethyl phthalate (DEP), diallyl phthalate (DAP), benzyl butyl phthalate (BBP), di-n-butyl phthalate (DBP), dihexyl phthalate (DHP), dicyclohexyl phthalate (DCHP), di-2-ethylhexyl phthalate (DEHP), di-n-octyl phthalate (DOP), diisononyl phthalate (DINP) and diisodecyl phthalate (DIDP) in children's PVC toys. The phthalates were extracted from PVC toy sample using ultrasonic extraction with methanol. Quantification analysis was achieved by gradient elution mode using reversed-phase ODS-4 C column with PAD detection at 226 nm.

Changing levels of selenium and zinc in cadmium-exposed workers: probable association with the intensity of inflammation.

Inflammation is a response mediated by multiple cytokines, such as IL-6, IL-10 and TNF-α. Cadmium (Cd) has been involved in the etiopathogenesis of many diseases via inflammation. Selenium (Se) and zinc (Zn) play a pivotal role in maintaining many physiological functions of cells as well as inhibiting Cd-induced cytotoxicity.

The effects of occupational lead exposure on selected inflammatory biomarkers.

In exposure to toxic metals such as lead, determining lead and cytokine levels (IL-6, IL-10, and TNF-α) is essential for early detection of diseases. The aim of this study was to develop an model for early detection of inflammation and onset of atherosclerosis in the absence of clinical findings in young workers, which could help physicians take timely an action and start treatment. This study included 49 metal workers exposed to lead occupationally and 50 unexposed administrative workers (controls) who underwent immunological analysis for cytokines (IL-6, IL-10, and TNF-α) and atherosclerosis markers (h-FABP and VCAM-1), toxicological analysis for lead, and routine biochemical analysis (ALT, AST, creatinine) at the Ankara Occupational and Environmental Diseases Hospital in 2017.

Arsenic-induced inflammation in workers.

Occupational and environmental exposures to metal and metalloids can result in neurotoxicity and immunotoxicity.
