Systemic Treatment of Psoriasis: Current Evidence on Efficacy and Safety

open access: yesThe Journal of Dermatology, EarlyView.
ABSTRACT Systemic treatments for moderate‐to‐severe plaque psoriasis have been advanced from broad immunosuppressants up to agents more selectively targeting cytokines, cytokine receptors, or intracellular signaling. The current systemic treatments mainly consist of conventional systemic agents, biologics targeting tumor necrosis factor (TNF)‐α ...

Economic Analysis of Infrastructure Investment and Break‐Even Carbon Prices for Low‐Water, Low‐Emission Farming Techniques in Vietnam

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Excessive water use in rice production is a major source of methane emissions, the dominant greenhouse gas from Vietnam's agricultural sector. Improving water‐use efficiency can enhance water security and reduce emissions, but achieving these gains requires substantial changes in farming practices and significant investment in supporting ...

The Constellation: A Reappraisal of Walter Benjamin's Influence on Theodor W. Adorno

open access: yesConstellations, EarlyView.
ABSTRACT In the 1920s and 1930s, Walter Benjamin and Theodor W. Adorno both sought to develop a notion of Darstellung—of philosophical presentation or representation—that could provide an alternative to the classically idealist tendency to subsume objects under abstract concepts.
