Cadmium (Cd) is a heavy metal that has received considerable environmental and occupational concern. Cd causes toxic effects due to its accumulation in a variety of tissues, including the kidney, liver and the nervous system (CNS); however, the exact mechanism is poorly understood. In the present study, we tried to explore the impact of acute cadmium exposure on rat brain phospholipids (PLs). Cd exposure significantly reduced PLs in a time dependent manner and the reduction was due to the activation of the Phospholipase A(2) enzymes (sPLA(2), cPLA(2)). The release of arachidonic acid from PLs increased during inflammatory conditions by PLA(2)s. The mRNA expression of cyclooxygenase2 (COX2) and subsequently the pro-inflammatory cytokines, namely, Interleukin 1 (IL-1) and IL-6, were up regulated; however, the expression of anti-inflammatory cytokine IL-10 was reduced in a time dependent manner. The expression of the Tumor necrosis factor alpha (TNF-alpha), Inducible nitric oxide synthase (iNOS) and Interferon gamma (INF-gamma) also experienced increases in the expression. Likewise the mRNA expression of the pro-apoptotic factor, Bcl-2-associated X protein (Bax), was elevated, whereas anti-apoptosis B-cell lymphoma 2 (Bcl2) was down regulated. This present study might help to decipher the effects of cadmium toxicity on rat brain.

Arsenic toxicity: sources, pathophysiology and mechanism
Shahid Yousuf Ganie, Darakhshan Javaid, Younis Ahmad Hajam, Mohd Salim Reshi
Summary: Arsenic toxicity is a complex and pervasive public health problem that affects millions of people worldwide. This review aims to consolidate current knowledge on arsenic toxicity, including its sources, chemical forms, and the pathways through which it affects human health. The study found that arsenic is associated with chronic diseases such as cancer, cardiovascular disorders, and neurotoxicity, and oxidative stress, genotoxicity, and epigenetic modifications play important roles in arsenic-induced cellular damage. Further research is needed to fill gaps in our understanding of arsenic toxicity and inform public health policies aimed at minimizing exposure.

Developmental neurotoxicity (DNT) QSAR combination prediction model establishment and structural characteristics interpretation
Lu Zhang, Min Li, Dalong Zhang, Shujing Zhang, Li Zhang, Xiaojun Wang, Zhiyong Qian
Summary: With the increasing incidence of neurodevelopmental disorders, it is important to screen and evaluate developmental neurotoxicity (DNT) compounds from a large number of environmental chemicals and understand their mechanisms. This study conducted a DNT qualitative structure-activity relationship (QSAR) study for the first time, and preliminarily illustrated the structural characterization of DNT compounds. Multiple models and methods were used to construct prediction models, resulting in the best model with good predictive ability. By combining different models, both MCC values and application domain values were improved. Additionally, through modeling descriptors analysis and structure alerts (SAs) identification, electronical properties, van der Waals volume-related properties, and S, Cl or P containing substructure were found to be associated with DNT. This study lays a foundation for further DNT prediction of environmental exposures in human and contributes to the understanding of DNT mechanism.

Impact of untreated and microbially treated equalization tank effluent of textile industry on freshwater fish Channa punctata using haematological, biochemical, histopathological and ultrastructural analysis
Khushboo Sharma, Satish Koundal, Mandeep Singh, Pooja Chadha, Harvinder Singh Saini
Summary: The unregulated discharge of untreated or partially treated industrial wastewater poses a serious threat to aquatic ecosystems. This study exposed Channa punctata fish to untreated and microbially treated textile industry effluent to analyze their toxicity effects. The results showed that the untreated effluent group had more severe hematological, biochemical, histopathological, and ultrastructural alterations compared to the microbially treated group. This highlights the importance of finding more effective microbial treatments to protect aquatic life and human health.

Mechanism of simulated lunar dust-induced lung injury in rats based on transcriptomics
Chen Gu, Yan Sun, Meiqi Mao, Jinguo Liu, Xiongyao Li, Xiaoping Zhang
Summary: This study investigated the mechanism of lunar dust simulant (CLDS-i) in inducing inflammatory lung injury. The results showed that CLDS-i regulated immune inflammatory cells and activated signaling pathways related to inflammatory diseases, promoting the occurrence and development of inflammatory injury. The study also found that amino acid metabolism imbalance might be related to the activation of the NF-kappa B signaling pathway.
