Head &Neck, EarlyView.ABSTRACT Background Head and neck cancer (HNC) is a devastating diagnosis, with advanced‐stage disease leading to poorer outcomes. This qualitative study aimed to identify health system factors associated with stage of HNC diagnosis. Methods Qualitative semistructured interviews with HNC patients and clinicians were undertaken in two purposively ...

Head &Neck, EarlyView.ABSTRACT Introduction Head and neck cancer (HNC) survival is improving, increasing the need to address long‐term survivorship issues. Dental survivorship—care before, during, and after treatment—remains inconsistent across services. We conducted a review of systematic reviews and emerging evidence to inform contemporary dental survivorship care for HNC

International Journal of Cancer, EarlyView.Although lenvatinib is the current first‐line therapy for radioiodine‐refractory differentiated thyroid carcinoma, its use is limited by severe side effects and reduced sensitivity. Here, the authors assessed the potential of sensitizing differentiated thyroid carcinoma tumor cells with limited lenvatinib responsiveness through the administration of ...

Field-Flow Fractionation Analysis of Complex Biological Samples [PDF]
Kemija u Industriji, 2014 Normal analytical methods have difficulties when analysing complex samples containing particles of different size. In the 1960s, a new analytical technique was developed, which was able to overcome those difficulties.

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals
Journal of Applied Toxicology, EarlyView.ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...
