R&D investments under financing constraints
We analyse the effect of credit supply constraints on R&D conditional on the financial strength of firms and heterogeneity in the restrictions in the supply of external financing. The financial strength of firms and access to external financing are identified by an exogenously calculated rating index.

This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Challenges for a Transition from Peasant Agriculture to a Business Agriculture in Burkina Faso
Since the national farmers' day on May 12, 2017 in Kaya, Burkina Faso, the debate on agriculture has been to establish the agricultural entrepreneurship through the concept of agriculture as a family business (ACEF).

Corporate governance, financial constraints, and dividend policy: Evidence from Pakistan
Information asymmetry between insiders and outsiders creates various issues for a firm, such as the agency problem where managers pursue their own interests even at the cost of the well-being of the firm’s shareholders, and probable external financial ...

Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

We investigate the impact of the financial crisis on the access of small and medium-sized enterprises in the Czech Republic to external financing. We apply the non-parametric kernel density estimation on a firm-level measure of financing constraints and ...

Molecular cancer prevention: Intercepting disease
Oncological practice must evolve, from treating established tumours to proactive cancer interception before clinical manifestation. This will require mechanistic insight into tumour initiation, validated biomarkers of early disease development and redesigned clinical trials, enabling cancer interception to become a core pillar of oncology with the ...

Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...
