Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

Polymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Baicalein Sensitizes Radioresistant BT549 and MCF7‐R Breast Cancer Cells by Modulating Rac1 Signaling

Phytotherapy Research, EarlyView.
ABSTRACT Radioresistance remains a key barrier in breast cancer (BC) treatment. Baicalein, a flavonoid from Scutellaria baicalensis, has shown potential to enhance radiosensitivity. This study investigates its efficacy and mechanism in radioresistant BC models. Radioresistant BC cell models were established via fractionated irradiation and validated by

Cross‐Linking Mass Spectrometry of the Antimicrobial Peptides Magainin 2 and PGLa Reveals Heterodimerization in Micellar Medium

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale In this study, we applied cross‐linking mass spectrometry (XL‐MS) to characterize the oligomeric states of a PGLa/magainin 2 mixture and gain insight into the heterodimerization previously suggested in the literature. Both peptides have shown a synergistic enhancement of activity when tested in antimicrobial assays; however, the ...

Unveiling power, or why social science's task is explanation

The British Journal of Sociology, EarlyView., 2023
Abstract This short essay contends that sociology should devote attention to causal explanation in order to expose lies. It argues that lies about causes are common in society and social science is in a unique privileged position to offer social knowledge that can dispel such lies. Offering causal explanations is a vital task of this project.

Integrating Sustainability Through Socio‐Scientific Issues in Chile: Towards a Decolonial Chemistry Education

Science Education, EarlyView.
ABSTRACT This study examines how integrating sustainability through socio‐scientific issue (SSI) in secondary chemistry teaching shapes epistemic openness and closure from a decolonial perspective, as mediated through classroom discourse. Drawing on a co‐planned lesson on copper mining in Chile – a scientifically rich yet ethically and politically ...

The Transformational STEM Consciousness Scale: A QuantCrit Measure of a Liberatory STEM Outcome

Science Education, EarlyView.
ABSTRACT Guided by QuantCrit, we introduce and validate the Transformational STEM Consciousness (TSC) scale, which fuses students' motivation to pursue racial and social justice through STEM with a critique of STEM's historic complicity in inequity. Surveying 255 undergraduate and graduate students in 18 justice‐integrated STEM courses across 11 US ...

Who Knows, Cares and Acts for Sustainability in Times of Uncertainty? Demographic Differences in Perceived Knowledge, Concerns, and Pro‐Environmental Behaviors

Sustainable Development, EarlyView.
ABSTRACT In 2026, some years after the Covid‐19 pandemic and the related economic crisis, the global landscape remains profoundly unsettled. Geopolitical conflicts, such as the war between Russia and Ukraine and the Middle East conflicts, continue to drive instability, reshaping global priorities and challenges.

How Brazilian Public Universities Are Operationalizing The SDGs: Strategic Plans Analysis

Sustainable Development, EarlyView.
ABSTRACT Despite the importance of universities for Sustainable Development, only a handful of studies have evaluated the implementation levels of SDGs in HEIs in Latin America. To fill this void, this study examines the strategic plans of 70 Brazilian public universities, which account for 92.8% of Federal Universities.
