The efficient removal of 99TcO4- from alkaline nuclear waste is vital for optimizing nuclear waste management and safeguarding the environment. However, current state-of-the-art sorbent materials are constrained by their inability to simultaneously achieve high alkali resistance, rapid adsorption kinetics, large adsorption capacity, and selectivity. In this study, we synthesized a urea-rich cationic porous organic polymer, IPM-403, which demonstrates exceptional chemical stability, ultrafast kinetics (~92% removal within 30 seconds), high adsorption capacity (664 mg/g), excellent selectivity, along with multiple-cycle recyclability (up to 7 cycles), making it highly promising for the removal of ReO4- (surrogate of 99TcO4-) from nuclear wastewater.

Background: Partial protective immunity to schistosomiasis develops over time, following repeated praziquantel treatment. Moreover, animals develop protective immunity after repeated immunisation with irradiated cercariae. Here, we evaluated development of natural immunity through consecutive exposure-treatment cycles with Schistosoma mansoni (Sm) in healthy, Schistosoma-naïve participants using single-sex controlled human Sm infection.

Article Synopsis
  • Shortwave-infrared (SWIR) imaging is suggested to improve contrast in fluorescence-guided surgery compared to near-infrared (NIR) imaging, but it has only been tested in animal studies so far.
  • The study aims to evaluate the benefits of SWIR imaging in clinical samples treated with the NIR dye cetuximab-IRDye800CW, focusing on tumor-targeted applications in penile and head and neck cancers.
  • Results indicate that while SWIR performs similarly to NIR in penile cancer samples, NIR outperforms SWIR in most criteria for head and neck cancer due to high background autofluorescence, suggesting that SWIR may enhance contrast in some situations but not universally across all clinical

Effective sequestration of bromine holds great promise for the chemical industry's safe expansion, environmental preservation, and public health. However, attaining this goal is still challenging due to the serious drawbacks of existing adsorbents such as limited capacity, low retention efficiency, and sluggish uptake kinetics. Herein, we report a strategy-driven systematic study aimed at significantly enhancing multiple host-guest interactions to obtain functionalized covalent-organic frameworks for the efficient sequestration of bromine.

Article Synopsis
  • Schistosomiasis is a neglected tropical disease that greatly affects children's health, prompting a study in Mwanga district, Tanzania, where mass drug administration has been ongoing for 20 years.
  • The study tested 576 school-aged children for schistosomiasis using different diagnostic methods, revealing a notable disparity in prevalence rates—20.3% with the UCP-LF CAA test versus 65.3% with combined POC-CCA and microhaematuria tests.
  • Key risk factors identified included younger age (5-10 years), and activities such as fishing, farming, and swimming, indicating ongoing transmission despite improvements from drug interventions.
