Orbiviruses infect a wide range of hosts, including humans. The ability to detect them has been hampered by their diversity. Here we present a simple consensus reverse transcription (RT)-PCR method targeting the polymerase gene for orbivirus recognition and characterization. Phylogenetic assignment is achieved by automated Web-based sequence analysis of amplification products.

Microbial mats are stratified communities often dominated by unicellular and filamentous phototrophs within an exopolymer matrix. It is challenging to quantify the dynamic responses of community members in situ as they experience steep gradients and rapid fluctuations of light. To address this, we developed a binary consortium using two representative isolates from hot spring mats: the unicellular oxygenic phototrophic cyanobacterium OS-B' (Syn OS-B') and the filamentous anoxygenic phototroph MS-CIW-1 (Chfl MS-1).

The rapid advancement of nanotechnology, particularly in the realm of pharmaceutical sciences, has significantly transformed the potential for treating life-threatening diseases. A pivotal aspect of this evolution is the emergence of "green nanotechnology," which emphasizes the environmentally sustainable synthesis of raw materials through biological processes. This review focuses on the biological synthesis and application of zinc oxide (ZnO) nanoparticles (NPs) from probiotic bacteria, particularly those sourced from wastewater.

Purpose: Trophoblast cell-surface antigen 2 (Trop2) is overexpressed in various solid tumors and contributes to tumor progression, while its expression remains low in normal tissues. Trop2-targeting antibody-drug conjugate (ADC), sacituzumab govitecan-hziy (Trodelvy), has shown efficacy in targeting this antigen. Leveraging the enhanced specificity of ADCs, we conducted the first immunoPET imaging study of Trop2 expression in gastric cancer (GC) and triple-negative breast cancer (TNBC) models using Zr-labeled Trodelvy ([Zr]Zr-DFO-Trodelvy).

The endo-lysosomal system plays a crucial role in maintaining cellular homeostasis and promoting organism fitness. The pH of its acidic compartments is a crucial parameter for proper function, and it is dynamically influenced by both intracellular and environmental factors. Here, we present a method based on fluorescence lifetime imaging microscopy (FLIM) for quantitatively analyzing the pH profiles of acidic endolysosomal compartments in diverse types of primary mammalian cells and in live organism .

Lateral roots (LRs), are an important component of plant roots, playing a crucial role in anchoring the plant in the soil and facilitating the uptake of water and nutrients. As post-embryonic organs, LRs originate from the pericycle cells of the primary root, and their formation is characterized by precise regulation of cell division and complex intercellular interactions, both of which are closely tied to cell wall regulation. Considering the rapid advances in molecular techniques over the past three decades, we reframe the understanding of the dynamic change in cell wall during LR development by summarizing the factors that precipitate these changes and their effects, as well as the regulated signals involved.
