A systematic review on human exposure to organophosphorus pesticides in Iran.

Human exposure to organophosphorus (OP) pesticides is a serious health challenge. We conducted a systematic review by searching international and national databases for published literature on any human exposure to OPs in Iran from 1990 to March 2015. Qualified papers were in two categories including studies in which biomarkers of exposure were assessed (n = 13; total no. of subjects = 759) and studies that had reported prevalence of OPs-induced poisoning (OPP) and mortality (n = 26; total no. of subjects = 5428). The mean level of activity of acetyl-cholinesterase and butyryl-cholinesterase were 68.65% and 74.2%, respectively. Overall proportion (%) of OPP was estimated (16; 95% CI, 14 to 19).

A systematic review on potential mechanisms of minocycline in kidney diseases.

Kidney diseases need specialized health care and still are a reason of death. There is a large body of evidence that indicates minocycline possesses some cytoprotective effects beside of antibacterial properties. In this review, we aimed to explain cytoprotective mechanisms and kidney protection of minocycline. In order to find the effects of minocycline on kidney diseases a systematic literature search was performed, according to the guidelines proposed at the PRISMA statement in the electronic databases, including: PubMed, Scopus, and Web of Science up to August 2016, using the term 'minocycline' combined either by 'kidney' or 'renal' and published in English language. The following criteria were included: (1) studies that used minocycline in renal diseases; (2) full-text articles; (3) English language; (4) no limitation in publications with in-vivo or in-vitro and human or animal subjects. Our search provided a total of 1056 articles which 1045 of them were discarded due to not meeting the inclusion criteria. It has been clear that several factors, including apoptosis, oxidative stress, mitochondrial dysfunction and inflammation have pivotal roles in the development and progression of kidney diseases. Minocycline protective properties are via several ways, including anti-apoptotic, free radical scavenging, anti-inflammatory, effect on mitochondrial functions and inhibition of matrix metalloproteinase. This systematic review confirmed that minocycline could have significant effects on treatment of renal malfunctions. However, regarding any possible adverse effects of antibiotics, it appears that more investigation is still needed in this context.
