Tumor B‐cell infiltration in platinum‐treated advanced muscle‐invasive urothelial carcinoma
Molecular Oncology, EarlyView.Bladder tumors with higher pretreatment memory B‐cell infiltration were linked to longer survival after cisplatin chemotherapy, but not carboplatin. These tumors also showed more organized immune structures (tertiary lymphoid structures) and a shared pro‐inflammatory B‐cell‐rich community, suggesting that memory B cells may help identify patients most ...

Problems of bearing currents in converter-fed electrical drives
, 2021 V pričujočem magistrskem delu so podrobneje opisani ležajni tokovi, ki kot posledica pretvorniškega napajanja kvarno vplivajo na delovanje asinhronskega motorja oz. v relativno kratkem časovnem obdobju degradirajo ali celo uničijo ležaja motorja.

FEBS Open Bio, EarlyView.Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Optimization of resistance spot welding parameters for microalloyed steel sheets
Open Engineering, 2016 The paper presents the results of resistance spot welding of hot-dip galvanized microalloyed steel sheets used in car body production. The spot welds were made with various welding currents and welding time values, but with a constant pressing force of ...
