abstract objective removing plasma from the platelet concentrate (pc) medium could be an effective way to increase the safety of this product. the goal of this study was to compare pc stored in plasma or in an additive solution (composol) with in vitro testing. materials and methods fifty-four single donor pcs were prepared from iranian blood transfusion organization (ibto). each pc unit was di...

The authors present the case of a 80 years-old woman, with no relevant medical history, which presented to the emergency department for fever (38--39◦C), chills, nausea and vomiting, and persistent pain in the right hypochondrium lasting for two days. Initial clinical assessment revealed hypotension, hypoxemia (pO2 < 70 mmHg), slight leukocytosis, CRP 176 mg/L and increased lactates (3.0 mmol)....

The Hill-Meyerhof theory of the recovery process occurring in the muscles after exercise postulates that four-fifths of the lactic acid formed is reconverted into muscle glycogen, while the remainder is oxidized. Since Meyerhof has shown that this cycle occurs in the isolated frog muscle, then the muscles themselves must be able to effect this transformation. The exact pathway by which lactic a...

Besides closed loop recycling approaches–monomer to product monomer–open is a promising strategy for circular plastics economy, preventing waste and the use of fossil resources. Polylactide (PLA), bio-based biodegradable polymer, polymerized by catalyst [FeCl2(TMG5NMe2asme)]. The same used depolymerization end-of-life PLA with different nucleophiles obtain value-added products like lactates or ...

The cover feature image shows that zinc guanidine complexes act with the yin-yang principle for bioplastics: they are able to promote controlled ring-opening polymerisation of lactide polylactide under industrial conditions but also recycling into lactates which go back value chain. Hence, corn as principal source can be saved since waste PLA serves resource allows multiple cycling valuable ren...
