There has been an increased interest in standardized approaches to coding facial movement mammals. Such include Facial Action Coding Systems (FACS), where individuals are trained identify discrete muscle movements that combine create a configuration. Some studies have utilized FACS analyze signaling, recording the quantity of morphologically distinct signals species can generate. However, it is unclear whether these numbers represent total number combinations (which we refer as...

The use of synthetic cannabinoids (SCs) increases dramatically among youth from different cultures. UR-144 is one these SCs that was reported in 2012 for its first abuse. Case reports show neuronal toxicity symptoms after exposure and a few laboratory studies cell death, apoptosis, oxidative stress lines. However, none those evaluate the cells. In this study, it hypothesized induces human neuroblastoma (SH-SY5Y) To test that, MTT neutral red uptake (NRU) assays were performed to...

Purpose: The wide application of cupric oxide nanoparticles (copper (II) oxide, CuO-NPs) in various fields has increased exposure to the kind active nanomaterials, which can cause negative effects on human and environment health. Although CuO-NPs were reported be harmful human, there is still a lack information related their toxic potentials. In present study, potentials evaluated liver (HepG2 hepatocarcinoma) intestine (Caco-2 colorectal adenocarcinoma) cells. Methods: After...

Lanthanum nanoparticles are widely used in industry, agriculture, and biomedicine. Over 900 kg of lanthanum is annually released into the environment only Europe, 50 times higher than metals, mercury, cadmium's environmental spread. Human health risk associated with long-term exposure to abundant a concerning issue. Due lanthanum's ability disrupt main biological barriers interrupt various cells' hemostasis, they seem cause severe disruptions tissues. This review opens new perspective...

Citrinin (CIT) is a mycotoxin produced as secondary product by the genera Aspergillus, Penicillium, Monascus, and other strains. CIT has potential for contaminating animal feed human food such maize, wheat, rye, barley, oats, rice, cheese, sake. Although primarily known nephrotoxic mycotoxin, it also affects organs, including liver bone marrow, its mechanisms of toxicity have not been clearly elucidated. There further lack studies investigating CIT-induced neurotoxicity mechanisms. In...
