Ochratoxin A (OTA) is a common fungal toxin frequently detected in food and human plasma samples. Currently, the physiologically based toxicokinetic (PBTK) model plays an active role in dose translation and can improve and enhance the risk assessment of toxins. In this study, the PBTK model of OTA in rats and humans was established based on knowledge of OTA-specific absorption, distribution, metabolism, and excretion (ADME) in order to better explain the disposition of OTA in humans and the discrepancies with other species.

Article Synopsis
  • Patients with diabetes are more susceptible to myocardial ischemia/reperfusion injury (MI/RI), and Shuxin decoction (SXT), a modified herbal formula, has shown promise in reducing this risk in clinical settings, though its mechanisms are not fully understood.
  • The study aims to explore how SXT mitigates MI/RI in diabetic patients using an ensemble model that combines network pharmacology and biology, identifying key components and therapeutic targets associated with the condition.
  • Results indicate that SXT may improve lipid metabolism and reduce apoptosis in MI/RI by decreasing oxidized LDL levels and targeting the RAGE signaling pathway, with animal trials supporting these findings through observed reductions in harmful substances and regulation of blood lipid levels.

Parkinson's disease is a health-threatening neurodegenerative disease of the elderly with clinical manifestations of motor and non-motor deficits such as tremor palsy and loss of smell. Alpha-synuclein (α-Syn) is the pathological basis of PD, it can abnormally aggregate into insoluble forms such as oligomers, fibrils, and plaques, causing degeneration of nigrostriatal dopaminergic neurons in the substantia nigra in the patient's brain and the formation of Lewy bodies (LBs) and Lewy neuritis (LN) inclusions. As a result, achieving α-Syn aggregate detection in the early stages of PD can effectively stop or delay the progression of the disease.

In order to investigate the modification of the surface structure of FePS via Ga ion irradiation, we study the effect of thickness and Raman spectrum of multilayer FePS irradiated for 0 μs, 30 μs, and 40 μs, respectively. The results demonstrate that the intensity ratio of characteristic Raman peaks are obviously related to the thickness of FePS. After Ga ion irradiation, the FePS sample gradually became thinner and the E peak and Eg(v) peak in the Raman spectrum disappeared and the peak intensity ratio of A(v) with respect to A(v) weakened.
