Abstract Regional innovation policies are currently influenced by a series of territorial innovation models, with the regional innovation system (RIS) approach being one of the prominent examples. The rationale of smart specialization strategies (S3s) is deeply influenced by the RIS concept and highlights the importance of entrepreneurial discovery and

pH-dependent effects of procaine on equine gamete activation [PDF]
Procaine directly triggers pH-dependent cytokinesis in equine oocytes and induces hypermotility in stallion spermatozoa, an important event during capacitation. However, procaine-induced hyperactivated motility is abolished when sperm is washed to remove

Abstract Global institutions are increasingly calling for an agroecological transition of our food systems to promote sustainable farmer livelihoods, safeguard agrobiodiversity and foster socio‐ecological resilience to a changing climate. Yet adoption remains limited, and there is a paucity of research examining how local conditions enable and ...

Capacitated vertex covering [PDF]
Summary: In this paper we study the capacitated vertex cover problem, a generalization of the well-known vertex cover problem. Given a graph \(G=(V,E)\) with weights on the vertices, the goal is to cover all the edges by picking a cover of minimum weight from the vertices. When we pick a copy of a vertex, we pay the weight of the vertex and cover up to

Heat Sensing Receptor TRPV1 Is a Mediator of Thermotaxis in Human Spermatozoa [PDF]
The molecular bases of sperm thermotaxis, the temperature-oriented cell motility, are currently under investigation. Thermal perception relies on a subclass of the transient receptor potential [TRP] channels, whose member TRPV1 is acknowledged as the ...

Multiple Roles of Protamine Kinase SRPK1 and Phosphatase PP1γ in Sperm Development
ABSTRACT Protein phosphorylation regulates key events of male germ cell differentiation. In the testis, SRPK1 and PP1γ are involved in protamine phosphorylation and dephosphorylation, respectively, and their deregulation is linked to defective chromatin structure and male infertility.

Capacitative Calcium Entry [PDF]
Capacitative Ca2+ entry is a recently discovered Ca2+ entry pathway that is activated on depletion of intracellular Ca2+ stores, providing an avenue for store refilling. Despite recent progress in elucidating the capacitative Ca2+ entry pathway, the mysteries of its molecular identity, its biophysical properties, and the store depletion signal remain.

Detecting extirpation: A localized approach to a global problem
The global biodiversity crisis stems from a cascading series of extirpations driving species toward extinction. Addressing this crisis requires methods for early detection of extinction at local scales, where communities can mobilize conservation efforts.

Cryoprotectant-free vitrification of human spermatozoa in new artificial seminal fluid [PDF]
Vitrification is a new method that has been recently introduced in Assisted Reproduction Technique programs. The aim of this study was to design a new medium similar to normal human seminal fluid (SF), formulation artificial seminal fluid (ASF), and to ...
