Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Biodegradable Zn‐based alloys are promising candidates for temporary implants, yet excessive Zn2+ release during degradation may induce cytotoxicity and adverse tissue responses. In this study, Zn‐xBa alloys (x = 0.1 wt%, 0.5 wt%, 1.0 wt% and 3.0 wt%) were developed to achieve controlled corrosion behaviors with improved biocompatibility.

Harnessing Trace Elements: Novel Radiosensitization Strategies for Enhanced Cancer Radiotherapy
Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Radiotherapy (RT) is one of the core methods of comprehensive cancer treatment. Globally, more than 40% of cancer patients rely on radiotherapy to achieve tumor control, cure or palliative relief. However, radiation resistance, immunosuppression and normal tissue injury limit its clinical application.

Sociologias Plurais, 2012 Comumente, em referência a atletas de futebol, evoca-se uma masculinidade tradicional (BONINO, 2008), definida como modelo social hegemônico. No presente artigo, refletir-se-á sobre a chamada "área reservada masculina" (MAGUIRE & DUNNING, 1997), considerada como relevante à manutenção das estruturas patriarcais. A partir de coberturas jornalísticas
