Copper Mitigates Atrazine-Induced Neurotoxicity in Parkinson's Disease Models.

Atrazine (ATR), one of the most prevalent herbicides used worldwide, has been associated with various environmental health concerns, including its potential role in promoting neurodegenerative diseases. Considering the pivotal role of metal homeostasis in the pathophysiology of neurodegenerative disorders, this study investigated the neuroprotective effects of copper supplementation in mitigating the adverse impacts of ATR in Parkinson's disease (PD). Our results reveal that ATR exposure disrupts copper and iron homeostasis within the substantia nigra pars compacta (SNpc), leading to enhanced oxidative stress and dopaminergic neuronal degeneration, which are key features of PD pathology.

Heterogeneity of Organoclay Complexes in Shale Regulates the Generation of Shale Oil.

Organic matter (OM) and clay minerals are important components in shale, which are intimately associated with each other in the form of organoclay complexes. The diverse mineral-OM associations result in varying OM occurrences, which possess distinct hydrocarbon generation potential and ultimately affect the accumulation of shale oil. Therefore, the investigation of the heterogeneity of organoclay complexes is crucial to gaining a comprehensive understanding of the varying exploration potential of shale oil resources.

[Advances in salivary exosomal miRNAs in head and neck squamous carcinoma].

Salivary exosomes are extracellular vesicles of 30-150 nm in diameter that exist in saliva and play an important role in substance exchange and signal transduction between cells, delivering the lipids, proteins and nucleic acids they carry to the recipient cells and regulating the physiological and pathological processes of the recipient cells. miRNA, as an important "cargo" in exosomes, is transported to the recipient cells and regulates the signaling pathways of the recipient cells, thus playing a regulatory role in disease progression. The miRNAs are transported to the recipient cells and regulate the signaling pathways of the recipient cells, thus playing a regulatory role in the progression of diseases.

Discovering common pathogenetic processes between COVID-19 and tuberculosis by bioinformatics and system biology approach.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic, stemming from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has persistently threatened the global health system. Meanwhile, tuberculosis (TB) caused by () still continues to be endemic in various regions of the world. There is a certain degree of similarity between the clinical features of COVID-19 and TB, but the underlying common pathogenetic processes between COVID-19 and TB are not well understood.

MicroRNA-217-5p triggers dopaminergic neuronal degeneration via autophagy activation under Atrazine exposure.

Atrazine (ATR) is a widely used agricultural herbicide, and its accumulation in soil and water can cause various environmental health problems. ATR has neurotoxic effects on dopaminergic neurons, which can lead to a Parkinson's disease (PD)-like syndrome. Epigenetics regulates gene expression dynamically through DNA methylation, histone post-translational modification, microRNA (miRNA) interaction, and RNA methylation.

ICU nurses' knowledge and attitude towards electrocardiogram interpretation in Fujian province, China: a cross-sectional study.

Introduction: The series of electrocardiograms (ECGs) can help track cardiac abnormalities in patients' conditions and make an earlier clinical decision. It is crucial for nurses working in critical care environments to acquire ECG knowledge for effective ECG monitoring and act accordingly in case of a change in patient condition. This study aimed at investigating intensive care unit (ICU) nurses' knowledge and attitude towards ECG interpretation in Fujian province, China.

Cadmium impairs the development of natural killer cells and bidirectionally modifies their capacity for cytotoxicity.

Cadmium (Cd) is a highly toxic heavy metal in the environment. The aim of this study was to investigate the impact of Cd on natural killer (NK) cells. C57BL/6 mice were treated with 10 ppm Cd via drinking water for 3 months, and the development of NK cells in the bone marrow (BM) and the cytotoxicity of mature NK (mNK) cells in the peripheral immune organs were evaluated thereafter; the impact of Cd on the cytotoxicity of mNK cells from human peripheral blood mononuclear cells (PBMC) was also investigated.

Lead suppresses interferon γ to induce splenomegaly via modification on splenic endothelial cells and lymphoid tissue organizer cells in mice.

Splenomegaly is a symptom characterized by the presence of an enlarged spleen. The impact of environmental factors on splenomegaly is largely unknown. In this study, C57BL/6 mice were treated with 125 ppm or 1250 ppm lead (Pb) via drinking water for 8 wk, and the process of splenomegaly was evaluated.

Effects of a spray-based oropharyngeal moisturising programme for patients following endotracheal extubation after cardiac surgery: A randomised, controlled three-arm trial.

Background: When a patient emerges from cardiac surgery, they may experience intense thirst and discomfort or even impaired swallowing after endotracheal extubation. This may lead to feelings of suffocation, desperation, fear, and anxiety. Although thirst relief and dysphagia prevention share similar mechanisms, there is limited evidence for a combined intervention to alleviate thirst and prevent dysphagia.

Prevalence of and risk factors for thirst in the intensive care unit: An observational study.

Aim And Objectives: This study investigated the incidence of thirst and contributing factors in intensive care unit (ICU) patients by analysing differences in physiologic, psychological, and disease- and environment-related parameters in ICU patients with vs without thirst.

Background: Little is known about the factors that influence thirst, and there are no standardised methods for identifying at-risk patients in the ICU. Previous studies generalised the risk of thirst in ICU patients because of a lack of data on relevant variables.

Cadmium Suppresses Bone Marrow Thrombopoietin Production and Impairs Megakaryocytopoiesis in Mice.

Cadmium (Cd) is a highly toxic heavy metal in our environment. The influence of Cd on the development of platelets, or megakaryocytopoiesis, remains to be defined. The aim of this study was to investigate the impact of Cd on megakaryocytopoiesis.

Cadmium exposure reprograms energy metabolism of hematopoietic stem cells to promote myelopoiesis at the expense of lymphopoiesis in mice.

Cadmium (Cd) is a highly toxic heavy metal in our living environment. Hematopoietic stem cells (HSC) are ancestors for all blood cells. Therefore understanding the impact of Cd on HSC is significant for public health.

Mercury Chloride Impacts on the Development of Erythrocytes and Megakaryocytes in Mice.

Lead in Synergism With IFNγ Acts on Bone Marrow-Resident Macrophages to Increase the Quiescence of Hematopoietic Stem Cells.

Lead (Pb) is a highly toxic heavy metal that broadly exists in our living environment. Although Pb has been shown to influence the development of immune cells, to date, the impact of Pb on hematopoietic stem cells (HSCs) in the bone marrow (BM) remains unknown. As people are ubiquitously exposed to Pb and HSC are essential for human health, understanding the impact of Pb on HSC is significant for public health.

Lead Impairs the Development of Innate Lymphoid Cells by Impeding the Differentiation of Their Progenitors.

Lead (Pb) is a heavy metal toxic to the immune system, yet the influence of Pb on innate lymphoid cells (ILC) remains to be defined. In this study, we found that occupationally relevant level of Pb exposure impaired ILC development at the progenitor level by activating Janus Kinase1. C57BL/6 mice treated with 1250 ppm, but not 125 ppm Pb acetic via drinking water for 8 weeks had reduced number of mature ILC, which was not caused by increased apoptosis or suppressed proliferation.

[Development of residual voltage testing equipment].

For the existing measurement methods of residual voltage which can't turn the power off at peak voltage exactly and simultaneously display waveforms, a new residual voltage detection method is put forward in this paper. First, the zero point of the power supply is detected with zero cross detection circuit and is inputted to a single-chip microcomputer in the form of pulse signal. Secend, when the zero point delays to the peak voltage, the single-chip microcomputer sends control signal to power off the relay.
