Adjunctive Therapeutic Plasma Exchange in Refractory Adult‐Onset Still's Disease Complicated by Secondary Macrophage Activation Syndrome: A Single‐Center Experience

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Adult‐onset Still's disease (AOSD) complicated by macrophage activation syndrome (MAS) carries substantial mortality. The role of therapeutic plasma exchange (TPE) remains uncertain. Methods We retrospectively analyzed patients with AOSD‐MAS treated with TPE at a single‐center.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

MECHANICAL ACTIVATION AND GEOPOLYMERISATION OF TAIWANESE FLY ASH

Rudarsko-geološko-naftni Zbornik
The use of raw fly ash in the production of cement and geopolymer products is limited due to its low reactivity. However, the reactivity of fly ash can be increased through a mechanical activation process, allowing for its wider use.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Leaching of gold from a mechanically and mechanochemically activated waste [PDF]

Acta Montanistica Slovaca, 2010
The intensification of leaching of gold from a waste using mechanical activation (milling in water) and mechanochemical activation(milling in thiourea solution) were studied as the pretreatment steps.
