The study of orchid flowers, fruits, and inflorescences is crucial due to the remarkable diversity of orchid species and their unique adaptations to pollinators and seed dispersers. However, our understanding of the evolution and development of these organs within the orchid family remains limited.

Low-carbon (LE) technologies have a significant potential to reduce the total carbon emissions in China.

De jongeren van nu groeien op met sociale media. Mogelijk heeft dat invloed op de ontwikkeling van herssengebieden die betrokken zijn bij sociale interactie. Crone en Konijn laten in dit overzichtsartikel in Nature Communications zien hoe neurowetenschappelijke kennis kan bijdragen aan een beter begrip…

Current therapies for patients with atherosclerosis are targeted primarily on reducing blood cholesterol, but this fails to prevent a large number of cardiovascular events.95 In order to identify new therapeutic strategies for treating atherosclerosis, it is important to study the interactions between…

This thesis aims to address offshore wind energy (OWE)-related environmental impacts.

This study attempts to understand how indigenous community institutions pose an important role in sustainable community-based development, including the integration between local culture and development.

Accurate prediction of the unbound drug concentration-time profile at the CNS target site is crucial for the assessment of the right drug concentration-effect relationship. PBPK models have supported the PK prediction of the CNS target sites and the translation of PK data between species and between…

One of the major limitations in culturing complex tissues or organs is the lack of vascularization in the cultured tissue. Development of a functional capillary bed could overcome this problem.

Growth hormone profiles are pulsatile and highly variable between individuals, limiting the implementation of mathemathical models to quantify an individual's secretion.

This thesis describes the design and development of subunit‐selective inhibitors of particular catalytically active subunits of human constitutive proteasomes and immunoproteasomes.

During post-embryonic development into adults, animals face an environment that fluctuates constantly. For example, in nutrient availability, temperature, and osmolarity (e.g., salt concentration).
