Nutrient losses via subsurface tile cause environmental degradation of aquatic ecosystems. Various management practices are primarily aimed at reduction of nitrate leaching in tile discharge; however, studies on leaching of other nutrients are limited. A replicated plot experiment was initiated in 2016 as part of the Long-Term Agroecosystem Research (LTAR) network Croplands Common Experiment to quantify the effectiveness of management practices on leaching of NO-N, total P, K, and S from drained soils.

The aim of this study was to identify core components of culturally safe and ethical biomarker and genomic research with Indigenous peoples in Australia, Aotearoa/New Zealand, Canada and the USA.
Methods: A scoping review with a systematic search strategy was conducted utilising electronic databases MEDLINE, EMBASE, PsychINFO, CINAHL and Global Health.
Article Synopsis
- The study focuses on the substantial impact arthritis conditions have on First Nations Peoples, who suffer more than non-First Nations Peoples and require culturally relevant health information for better support.
- Utilizing a mixed-methods approach, the research included interviews with Aboriginal individuals about their needs for arthritis education and reviewed existing clinical practice guidelines for high-quality content.
- Findings from 30 Aboriginal participants led to recommendations for educational resources, emphasizing the effects of arthritis, access to care, and management strategies tailored to their cultural context.
Dichalcogenoimidodiphosphinate complexes of zinc [Zn{(EPPr)N}], [E=Se,Se; S,Se] were synthesized through metathetical reactions from the dichalcogenoimidodiphosphinate ligands [(EE'PPrNH)] (E, E'=Se, Se; S, Se). These complexes were characterized and used as single-source precursors through Aerosol-Assisted Chemical Vapour Deposition (AACVD) for the deposition of cubic zinc selenide (ZnSe) films on glass substrates. The deposition temperature occurred at 500 and 525 °C, while the flow rates of the carrier gas was 160 and 240 standard cubic centimetre (sccm).

- The study followed patients with early-stage follicular lymphoma (ESFL) who were treated with involved field radiotherapy (IFRT) alone or combined with chemotherapy (cyclophosphamide/vincristine/prednisolone) and later added rituximab to the treatment, analyzing its effects over an 11.3-year period.* -
- Results showed that those receiving IFRT plus rituximab (IFRT + R-CVP) had significantly better progression-free survival rates (62% vs. 43%) compared to IFRT alone, even though overall survival rates didn’t differ significantly.* -
- Additionally, higher expression of the CD8A gene in biopsy samples was associated with improved outcomes, suggesting that immune
