T-2 toxin, a highly toxic type A trichothecene, is a secondary fungal metabolite produced by various Fusarium species. The consumption of food and feed contaminated with T-2 toxin is a major factor contributing to growth retardation, posing significant risks to both human and animal health. However, the specific targets and mechanisms that mitigate T-2 toxin-induced growth retardation remain unclear.

Spectral collinearity and limited spectral datasets are the problems influencing Chemical Oxygen Demand (COD) modeling. To address the first problem and obtain optimal modeling range, the spectra are preprocessed using six methods including Standard Normal Variate, Savitzky-Golay Smoothing Filtering (SG) etc. Subsequently, the 190-350 nm spectral range is divided into 10 subintervals, and Interval Partial Least Squares (IPLS) is used to perform PLS modeling on each interval.

Article Synopsis
  • The study examines national standard methods for measuring water quality indicators like Temperature, pH, Turbidity, Conductivity, and TDS, noting that traditional chemical methods can lead to secondary pollution due to liquid residue.
  • It introduces a water quality monitoring system that simplifies the measurement process by analyzing historical data from five sensors, providing real-time graphical displays, and early warnings about water quality standards being exceeded.
  • Results indicate that the system performs well in measuring key indicators, with low average measurement errors and a small percentage of outlier data; it also finds the K nearest neighbor algorithm the most effective for dealing with outliers, aiding decisions on equipment maintenance and water quality management.

  • Bacterial lipopolysaccharide (LPS) exposure leads to intestinal inflammation and reduced growth in weaned piglets, impacting the swine industry economically.
  • Baicalin, a compound from Scutellaria baicalensis, may alleviate this inflammation through its anti-inflammatory properties.
  • The study suggests that baicalin targets the PARP1 protein to regulate inflammation-related pathways, potentially serving as a therapeutic option for LPS-induced intestinal injury.

Deoxynivalenol (DON) is one of the most prevalent mycotoxins in feed, which causes organ toxicity in animals. Therefore, reducing DON-induced organ toxicity can now be accomplished effectively using protective agents. This review provides an overview of multiple studies on a wide range of protective agents and their molecular mechanisms against DON organ toxicity.

Deoxynivalenol (DON) is one of the most serious mycotoxins that contaminate food and feed, causing hepatocyte death. However, there is still a lack of understanding regarding the new cell death modalities that explain DON-induced hepatocyte toxicity. Ferroptosis is an iron-dependent type of cell death.

Background: At present, the treatment and prevention of infections in pigs mainly rely on antibiotics and vaccines, but inflammatory injury cannot be eliminated. The compound 18β-glycyrrhetinic acid (GA), a pentacyclic triterpenoid extracted from . root (liquorice) and with a chemical structure similar to that of steroidal hormones, has become a research focus because of its anti-inflammatory, antiulcer, antimicrobial, antioxidant, immunomodulatory, hepatoprotective and neuroprotective effects, but its potential for the treatment of vascular endothelial inflammatory injury by infections has not been evaluated.

Growth retardation is a global public health problem that is highly prevalent especially in low-and middle-income countries, which is closely related to the consumption of grains contaminated with T-2 toxin, a risk for human and animal health. However, the possible targets that can relieve T-2 toxin-induced growth retardation still need to be explored. In the present study, T-2 toxin was used as an environmental exposure factor to induce growth retardation and further explore the regulatory role of lncRNA in growth retardation.

Glyphosate (GLYP) is a widely used pesticide; it is considered to be a safe herbicide for animals and humans because it targets 5-enolpyruvylshikimate-3-phosphate synthase. However, there has been increasing evidence that GLYP causes varying degrees of toxicity. Moreover, oxidative stress and metabolism are highly correlated with toxicity.

DON is commonly found in foods and feeds; it presents health risks, especially an increase of growth inhibition in humans, particularly infants and young children. However, there are relatively few research studies devoted to the mechanism of DON-mediated growth retardation. Interestingly, our results showed that DON does not cause any significant production of ROS but results in a persistent and significant release of NO with iNOS increasing activity, mitochondrial ultrastructural changes and decreasing ΔΨm.

Article Synopsis
  • - Monitoring has revealed a significant increase in low-level antibiotic pollutants, particularly enrofloxacin (ENR) and ciprofloxacin (CIP), with unmetabolized antibiotics posing a threat.
  • - Current research primarily focuses on each antibiotic separately, lacking studies on their combined effects on metabolism, specifically how CIP influences ENR in pigs.
  • - The study found that CIP alters ENR's pharmacokinetics by inhibiting CYP3A29, leading to higher ENR residues in pigs, which necessitates extending withdrawal periods and avoiding their combined use in animals meant for food production to protect human health.

As a continuation of our research on antimycobacterial agents, a series of novel quinoxaline-1,4-di-N-oxides (QdNOs) containing various nitrogenous heterocyclic moieties at the R position were designed and synthesized. Antimycobacterial activities, as well as the cytotoxic effects, of the compounds were assayed. Four compounds (6b, 6f, 6n, and 6o), characterized by 2-carboxylate ethyl or benzyl ester, 6-imidazolyl or 1,2,4-triazolyl, and a 7-fluorine group, exhibited the most potent antimycobacterial activity against M.

Obesity syndromes, characterized by abnormal lipid, cholesterol, and glucose metabolism, are detrimental to human health and cause many diseases, including obesity and type II diabetes. Increasing evidence has shown that long noncoding RNA (lncRNA), transcripts longer than 200 nucleotides that are not translated into proteins, play an important role in regulating abnormal metabolism in obesity syndromes. For the first time, we systematically summarize how lncRNA is involved in complex obesity metabolic syndromes, including the regulation of lipid, cholesterol, and glucose metabolism.
