Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae
FEBS Open Bio, EarlyView.Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Bootstraping cointegration tests under structural co-breaks: a robust extended ECM test [PDF]
, 1998 The aim of the paper is the analysis of ECM bootstrap cointegration tests under structural breaks. Classical ECM tests depend on sorne nuisance parameters, which is an undesirable feature for empirical applications.

Poland–USA sectoral trade balances: regime shifts and the nonlinear impact of currency fluctuations [PDF]
Central European Management JournalPurpose – The Polish economy has undergone major challenges and changes over the past few decades. The country's trade flows, in particular, have become more firmly tied to the country’s Western neighbors as they have grown in volume. This study examines

Versatile vector tools for efficient protein screening across multiple expression systems
FEBS Open Bio, EarlyView.A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

FEBS Open Bio, EarlyView.IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

Structural Changes in the Iranian Economy: An Empirical Analysis with Endogenously Determined Breaks [PDF]
This paper employs annual time series data (1960-2003) and the ZA (Zivot and Andrews, 1992) and the LP (Lumsdaine and Papell, 1997) approaches to determine endogenously the more likely time of major structural breaks in various macroeconomic variables of
