CCL22 and CCR4 Gene Polymorphisms in Myocardial Infarction: Risk Assessment of rs4359426 and rs2228428 in Iranian Population

[More] BACKGROUND: Myocardial infarction (MI) is an irreversible damage of myocardial tissue caused by prolonged ischemia and hypoxia. A local hypoxia-induced inflammation causes recruitment of leukocytes to the inflammatory site to aid cardiac remodeling and tissue healing. Among various chemokines involved in the process, CCL22 plays an essential role in cardiac cell migrations. In this study, we evaluated the incidence of rs4359426 and rs2228428 SNPs in CCL22/CCR4 genes of MI patients and studied their association with the physiology of the disease.

METHODS: Two hundred patients aged 30 - 70 years diagnosed with myocardial infarction along with 200 agematched healthy controls were registered in the study and their pathophysiological findings were recorded. Genotypic analysis of rs4359426 and rs2228428 in CCL22 and CCR4 genes, respectively, were carried out in patients using PCR-RFLP method and compared with the control group. Successively genotyped SNPs were reviewed for their possible association with the disease or physiological findings using Fisher's exact test.

RESULTS: The frequency of CC genotypes atboth SNPs rs4359426 and rs2228428 in CCL22 and CCR4 genes was significantly higher in MI patients compared to other genotypes.

CONCLUSIONS: Although we could not establish any direct association with the disease due to restricted population size, it is possible that CC genotypesin CCL22 and CCR4 could be considered as risk factors in myocardial infarction.

[More] The female reproductive system is a complicated, hormone-dependent group of tissues that may provide an interpretative challenge. The objectives of this chapter are to equip the reader with the background for designing rigorous in vivo experiments, discerning and interpreting study-related findings, and thoughtfully applying these data for the purpose of human safety assessment. The chapter focuses on the most common species used in general toxicology studies—the rat, beagle dog, and cynomolgus monkey. There is a systematic description of the normal, dynamic tissue changes and endocrinology observed in these species during their reproductive cycle. The chapter then presents a review of the responses of the female reproductive system to various xenobiotics, and describes approaches to characterize mechanistically these patterns of toxicity.

Maternal thyroid hormone insufficiency during pregnancy and risk of neurodevelopmental disorders in offspring: A systematic review and meta-analysis

[More] BACKGROUND: In the last 2 decades, several studies have examined the association between maternal thyroid hormone insufficiency during pregnancy and neurodevelopmental disorders in children and shown conflicting results.

AIM: This systematic review aimed to assess the evidence for an association between maternal thyroid hormone insufficiency during pregnancy and neurodevelopmental disorders in children. We also sought to assess whether levothyroxine treatment for maternal thyroid hormone insufficiency improves child neurodevelopment outcomes.

METHODS: We performed systematic literature searches in MEDLINE, EMBASE, PSYCinfo, CINAHL, AMED, BNI, Cochrane, Scopus, Web of Science, GreyLit, Grey Source and Open Grey (latest search: March 2017). We also conducted targeted web searching and performed forwards and backwards citation chasing. Meta-analyses of eligible studies were carried out using the random-effects model.

RESULTS: We identified 39 eligible articles (37 observational studies and 2 randomized controlled trials [RCT]). Meta-analysis showed that maternal subclinical hypothyroidism and hypothyroxinaemia are associated with indicators of intellectual disability in offspring (odds ratio [OR] 2.14, 95% confidence interval [CI] 1.20 to 3.83, P = .01, and OR 1.63, 95% CI 1.03 to 2.56, P = .04, respectively). Maternal subclinical hypothyroidism and hypothyroxinaemia were not associated with attention deficit hyperactivity disorder, and their effect on the risk of autism in offspring was unclear. Meta-analysis of RCTs showed no evidence that levothyroxine treatment for maternal hypothyroxinaemia or subclinical hypothyroidism reduces the incidence of low intelligence quotient in offspring.

LIMITATIONS: Although studies were generally of good quality, there was evidence of heterogeneity between the included observational studies (I2 72%-79%).

CONCLUSION: Maternal hypothyroxinaemia and subclinical hypothyroidism may be associated with intellectual disability in offspring. Currently, there is no evidence that levothyroxine treatment, when initiated 8- to 20-week gestation (mostly between 12 and 17 weeks), for mild maternal thyroid hormone insufficiency during pregnancy reduces intellectual disability in offspring.

[More] Perfluoroalkyl acids (PFAAs) have been suspected to act as endocrine disruptors and adversely affect human reproductive health. We aimed to investigate the association between PFAAs in blood and semen, explore a potential link between PFAAs exposure and semen quality in the population of the Pearl River Delta (PRD) region in China, one of the "world factories". The monitoring results demonstrated that the population (103 male participants) from the PRD region in this study had higher PFAAs levels in blood and semen than some other areas in China. PFOS was found at the highest mean concentrations of 118.16 ng/mL in blood and 5.31 ng/mL in semen among the nine PFAAs. Significant associations were found between concentrations of several analytes in blood and semen, including Σ9 PFAAs (r = 0.475, P < .01), PFOA (r = 0.215, P = .029), PFHS (r = 0.458, P < .01) and PFOS (r = 0.981, P < .01). BMI was the most important factor to PFAAs, but there was no significant difference in PFAAs concentrations in blood and semen collected from participants with different smoking and drinking habits, education background and occupations. Negative correlations were significantly observed between sperm motility and PFBA, PFPeA, PFHxA, PFBS, PFOA, PFHS, PFOS and Σ9PFAAs in semen. Therefore, exposure to PFAAs may result in a decline in semen mobility in participants from the PRD region.

[More] Covalent organic frameworks (COFs), which are a new type of carbonaceous polymeric material, have attracted great interest because of their large surface area and high chemical and thermal stability. However, to the best of our knowledge, no work has reported the use of magnetic COFs as adsorbents for magnetic solid-phase extraction (MSPE) to enrich and determine environmental pollutants. This work aims to investigate the feasibility of using covalent triazine-based framework (CTF)/Fe2O3 composites as MSPE adsorbents to enrich and analyze perfluorinated compounds (PFCs) at trace levels in water samples. Under the optimal conditions, the method developed exhibited low limits of detection (0.62-1.39 ng·L-1), a wide linear range (5-4000 ng L-1), good repeatability (1.12-9.71%), and good reproducibility (2.45-7.74%). The new method was successfully used to determine PFCs in actual environmental water samples. MSPE based on CTF/Fe2O3 composites exhibits potential for analysis of PFCs at trace levels in environmental water samples.
