Lead (Pb) contamination in wheat grain is of great concern, especially in North China. Atmospheric deposition is a major contributor to Pb accumulation in wheat grain. Screening low Pb accumulating wheat varieties has been an effective method for addressing Pb contamination in wheat grain.

Accurate estimation of desert vegetation transpiration is key to regulating desert water resources of desert ecosystems. Sap flow density (SFD) can indirectly reflect a tree's transpiration consumption, and it has been affected by climate warming and groundwater depths in desert ecosystems. Sap flow responses to meteorological conditions and groundwater depths are further affected by tree of different sizes.

Schistosomiasis, caused by Schistosoma spp., is a zoonotic parasitic disease affecting human health. Rattus norvegicus (rats) are a non-permissive host of Schistosoma, in which the worms cannot mature and cause typical egg granuloma.

Background: Macrophages and neutrophils are rapidly recruited around Schistosome eggs to form granulomas. Extracellular traps (ETs) of macrophages and neutrophils are part of the pathogen clearance armamentarium of leukocytes. Schistosome eggs possess the ability to resist attack by the host's immune cells and survive by employing various immune evasion mechanisms, including the release of extracellular vesicles (EVs).

snails play a crucial role in the transmission of the human blood fluke . The gut microbiota of intermediate hosts is known to influence their physiological functions, but little is known about its composition and role in snails. To gain insights into the biological characteristics of these freshwater intermediate hosts, we conducted metagenomic sequencing on and to investigate variations in their gut microbiota.

Liver fibrosis can occur in many chronic liver diseases, and no effective treatments are available due to the poorly characterized molecular pathogenesis. Semaphorin 4D (Sema4D) has immune functions and serves important roles in T cell priming. Here, we found that Sema4D was highly expressed in fibrotic liver, and the expression of Sema4D increased with hepatic stellate cells (HSCs) activation.

Background: Angiostrongylus cantonensis (A. cantonensis) infection can induce acute inflammation, which causes meningoencephalitis and tissue mechanical injury to the brain. Parasite infection-induced microRNAs play important roles in anti-parasite immunity in non-permissive hosts.

Article Synopsis
  • A globally distributed food-borne parasite can remain in a host for a long time post-infection, with secretions affecting the host's immune response and fibroblast activity, though mechanisms are not fully understood.
  • The study focused on analyzing the role of larvae-derived extracellular vesicles (EVs) and their specific miRNAs in how the parasite interacts with its host.
  • Results showed that the larvae EVs and certain miRNAs promote M2b macrophage polarization while suppressing fibroblast activation, helping to clarify the molecular dynamics of host-parasite interactions.

Self-healing hydrogels have great application potential in the field of bio-sensors due to their self-healing, flexibility and excellent tensile properties. However, most hydrogel-based sensors are processed by template method, which is unable to fabricate complex three-dimensional (3D) structures, and limits the development of hydrogel-based sensor devices. A simple yet efficient one-pot method was proposed to fabricate polyvinyl alcohol/sodium tetraborate/sodium alginate hydrogel inks (SPB), also a fabricating process of self-healing hydrogel based on 3D printing technology has been proposed.

Article Synopsis
  • Sensors are devices that detect changes in the environment and convert them to electrical signals, with flexible sensors offering advantages in health and biomedicine due to their ability to adapt to their surroundings.
  • Hydrogels are ideal materials for flexible sensors because they are both flexible and biocompatible, providing better stretchability compared to traditional elastomer-based sensors.
  • The paper reviews self-healing hydrogel flexible sensors, discussing their mechanism, conductivity, advantages and disadvantages, and identifying challenges and future recommendations for improvement.
