Summary: This study investigates the embryonic toxicogenomic responses induced by Zinc pyrithione (ZPT) in zebrafish. The results show that ZPT treatment causes embryogenesis toxicity, including irregular cell division and rearrangement, delayed differentiations of eyes and notochords, and defects in epiboly and germ ring formation and somite segmentation. ZPT exposure also alters gene expression during early embryonic development, leading to morphological abnormalities and metabolic dysfunctions. Additionally, ZPT induces oxidative stress, apoptosis, endoplasmic reticulum (ER) stress, and autophagy.

Summary: This study investigated the effects of swimming exercise on oxidative stress and liver cell damage caused by electromagnetic radiation in rats. The results showed that swimming exercise attenuated the liver damage caused by electromagnetic radiation. In the electromagnetic radiation group, the activity of superoxide dismutase and catalase decreased significantly, and the concentration of malondialdehyde and liver enzymes increased significantly; while in the swimming exercise and electromagnetic radiation + swimming exercise groups, the activity of superoxide dismutase and catalase increased significantly, and the concentration of malondialdehyde and liver enzymes decreased significantly.

Summary: Electromagnetic radiation can cause injuries to the heart, and there is currently no therapy available to prevent these effects. This study investigated the role of Sirtuin 3 (SIRT3) in electromagnetic radiation-induced cardiomyopathy (eRIC). The study found that Sirt3 expression was down-regulated in eRIC mice, and its overexpression protected the heart from the detrimental effects of radiation. It was also found that Sirt3 maintained the AMP-activated protein kinase (AMPK) signaling pathway in stressed hearts. These findings suggest that SIRT3 could be a potential therapeutic target for treating eRIC.

Summary: The study demonstrated that pre- and post-treatment of PRP could reduce MDA content and increase antioxidant enzyme activities in UVB-damaged HaCaT cells. Additionally, PRP intervention promoted cell proliferation via PI3K/AKT pathway, suppressed the expression of gamma-H2AX, upregulated TIMP-1 expression while downregulating MMP expression levels in photoaged HaCaT cells, ultimately playing an anti-photoaging role.

Summary: Zinc is an important trace element that plays a crucial role in growth, development, and male reproductive functions. Marginal zinc deficiency can lead to spermatogenic dysfunction in males. This study aimed to investigate methods to improve spermatogenic dysfunction caused by marginal zinc deficiency and explore the underlying mechanism. The results showed that zinc supplementation reduced oxidative stress levels and enhanced testicular cells' ability to resist apoptosis, thereby improving spermatogenic dysfunction caused by marginal zinc deficiency.

Summary: The present study demonstrated that exposure to 2.856 GHz microwave radiation caused significant structural and functional impairments of the male reproductive system, including hormone disorder, decreased sperm motility, depleted sperm energy, and abnormalities of testicular structure as well as mitochondrial impairment. However, metformin was found to effectively protect the reproductive system against these damages by inhibiting oxidative stress and apoptosis, indicating its potential as a promising antioxidant to mitigate the harmful effects of microwave radiation.

Summary: This in vitro study demonstrated that metformin can inhibit the proliferation and metastasis of primary breast cancer cells by modulating MMP-2 and MMP-9 expressions and interfering with the NF-kB signaling pathway. The highest inhibition was observed at a dose of 25 mM Metformin, which downregulated MMP-9 expression and blocked NF-kB activity and nuclear translocation. Metformin may play an essential antitumor role in the invasion and metastasis pathways of PBCCs.

Summary: As the use of mobile phones becomes more widespread, concerns about their impact on human health are growing. A study has found that the electromagnetic field (EMF) emitted by mobile phones may have negative effects on biological systems. This study investigates the effect of 2100 MHz EMF exposure on cancer fibroblast cells and explores the potential of zinc supplementation to mitigate these effects, finding that EMF exposure increases NF-kappa B and DNMT activities, while zinc supplementation reduces them.

Summary: Mammary carcinoma, or breast cancer, is the most common cancer type among women. Researchers are investigating potential new technologies for its diagnosis and treatment. One promising technique is using microwave applications to differentiate between malignant and normal tissues based on their dielectric properties. However, the current measurement technique is not accurate enough, so a new method is needed for confident detection of anomalies. This study proposes a classification method for rat mammary carcinoma based on large-scale in vivo S-11 measurements and corresponding tissue dielectric properties. Using a learning-based linear classifier, the tissues were classified with high accuracy, achieving an 86.92% accuracy when using the most discriminative S-11 measurement. These findings suggest that a narrow band microwave circuitry can support a low-cost automated microwave diagnostic system.

Summary: This study aimed to investigate the association between superoxide dismutase-1 (SOD1) promoter region Ins/Del gene variations and chronic gastritis patients infected with H. pylori, as well as the effects of trace elements and viscosity. The results showed that zinc (Zn), copper (Cu), iron (Fe), and magnesium (Mg) levels decreased, while whole blood viscosity (WBV), selenium (Se), and Cu/Zn ratio increased in H. pylori (+) chronic gastritis patients. The Ins/Del gene polymorphism in the SOD1 promoter region was not associated with chronic gastritis.

Summary: This study investigates the effects of phthalates on rat livers using SAM, RS, and ICP-OES for the first time in the literature. The results show modifications in tissue components due to exposure to DEHP and DBP, with increased element levels within the tissues of rats exposed to these phthalates. Additionally, the presence of DEHP alters the configuration and conformation of lipids and fatty acids in liver tissues.
