Opium may affect coronary artery disease by inducing inflammation but not through the expression of CD9, CD36, and CD68.

The molecular mechanisms of opium action with regard to coronary artery disease (CAD) have not yet been determined. The aim of this study was to evaluate the effect of opium on the expression of scavenger receptors including CD36, CD68, and CD9 tetraspanin in monocytes and the plasma levels of (TNF-α), (IFN-γ), malondialdehyde (MDA), and nitric oxide metabolites (NO) in CAD patients with and without opium addiction. This case-control study was conducted on three groups: (1) opium-addicted CAD patients (CAD + OA, n = 30); (2) CAD patients with no opium addiction (CAD, n = 30); and (3) individuals without CAD and opium addiction as the control group (Ctrl, n = 17).

Organochlorine pesticides induce thyroid tumors through oxidative stress; an in vivo and in silico study.

Thyroid disease is one of the most common endocrine problems around the world. Among the numerous factors, exposure to environmental elements such as pesticides is associated with an increase in the incidence of thyroid disorders. The aim of the present study was to investigate the role of organochlorine pesticides (OCPs) in induction of oxidative stress (OS) and development of thyroid tumors.

Organochlorine and organophosphorus pesticides may induce brain cancer through oxidative stress.

In this study, oxidative stress was investigated as the possible mechanism of action of organochlorine pesticides (OCPs) and organophosphorus pesticides (OPPs) in primary brain tumors (PBT). The levels of seven OCP residues and enzymatic antioxidant biomarkers including erythrocyte acetylcholinesterase (AChE), superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT), and paraoxonase-1 (PON-1) along with non-enzymatic oxidative biomarkers including malondialdehyde (MDA), protein carbonyl (PC), total antioxidant capacity (TAC), and nitric oxide (NO) were measured in blood samples of 73 patients with PBT and 104 healthy controls. A significant association was found between farming activities and PBT (55% of patients were engaged in farming activities while 45% had no farming experience).

Ultrafiltration Membranes Functionalized with Copper Oxide and Zwitterions for Fouling Resistance.

Polymeric membrane fouling is a long-standing challenge for water filtration.
