Paraquat®, or N,N′-dimethyl-4,4′-bipyridinium dichloride, is a bipyridyl compound used as a non-selective herbicide and desiccant that can cause acute poisoning through all routes of exposure. There is no known antidote, and the available treatments are based on avoiding its absorption and timely removing it, in adults and children. We describe a case series of 14 pediatric patients from the department of Cauca, Colombia, with acute intoxication after oral intake of paraquat. Patients were referred to a medium-high complexity hospital in southwestern Colombia and treated according to an institutional protocol for acute paraquat poisoning. Acute paraquat poisoning after oral ingestion is associated with a high mortality rate, even with timely medical attention, as the compound has no known antidote and quickly reaches systemic concentrations for fulminant poisoning. Based on the available literature, our center has proposed a clinical protocol including early standard management, immunosuppressive and antioxidant treatments, and systemic removal techniques. This protocol suggests an adequate approach to acute paraquat poisoning in the pediatric population.

Paraquat, a commonly available herbicide, when consumed in high doses, affects organs with high blood flow (lungs, heart, kidney and liver), leading to pulmonary fibrosis, respiratory failure and death. Few reports of rescue lung transplantation exist. Complete depletion of paraquat from the body is necessary prior to transplant; however, timing for and concerns after lung transplantation remain unknown.

Brown algae such as (AN) and (FV) are gaining considerable attention as functional feed additives due to their health-beneficial properties. This study evaluated the antioxidant potential of AN and FV extracts in intestinal epithelial cells and the in vivo model (). Aqueous AN and FV extracts were characterized for total phenolic content (TPC), antioxidant capacity (TEAC, FRAP), and phlorotannin composition using LC-HRMS/MS.

Alveolar edema and following respiratory distress results in the aggravation of epithelial damage and the progression of acute lung injury (ALI), however, with unclear molecular mechanism remained to be elucidated. Through proteomic screening and scRNA-seq mining analysis, we detected the decline expression of NDUFS1 in epithelial cells in lungs from paraquat/LPS-induced ALI models. NDUFS1 deficiency in alveolar epithelial cells reduced ENaCα expression, which impaired alveolar fluid clearance (AFC) and led to alveolar edema.

Autophagy inhibition induced by paraquat (PQ) poisoning is an important factor causing multi-organ damage, including renal tissue. Dihydrocapsaicin (DHC), the main active ingredient in chili peppers, was reported to induce autophagy, but its effect on PQ-induced AKI remains unclear. Rats were intraperitoneally injected with 25 mg/kg PQ to establish AKI rat model followed immediately by DHC administration (2.

Background: Oxidative stress can impair intestinal barrier function and cause liver damage, resulting in reduced animal productivity. Paraquat (PQ) induces significant oxidative stress in weaned piglets. The antioxidant, anti-inflammatory, and metabolic regulatory functions of taurine (Tau), a free amino acid that is widely distributed in the body, have been extensively studied.
