Critical Role of Skin in Pathogenesis: Bidirectional Crosstalk Between Skin and Multiple Organs

MedComm – Future Medicine, Volume 4, Issue 2, June 2025.
The skin functions as both a protective barrier and an autonomous immune organ, maintaining dynamic interactions with internal organs. This review analyzes skin‐organ crosstalk mechanisms, highlighting key cytokines (particularly IL‐17A) and microbial metabolites that mediate interorgan communication.

Innovative cooling solutions of HPDC technology

Multidiszciplináris Tudományok
In High Pressure Die Casting (HPDC), the so-called sliders are moving components of the mould, that can form cavities, holes, and undercuts. Sliders differ greatly from fixed- and moving mould halves regarding cooling and thermal balance. Typically, mould halves can range from a few hundred kilograms to several tonnes in size, whereas sliders have a ...

4D Biofabrication of Magnetically Augmented Callus Assembloid Implants Enables Rapid Endochondral Ossification via Activation of Mechanosensitive Pathways

Advanced Science, Volume 12, Issue 15, April 17, 2025.
Magnetically augmented biohybrid cartilaginous microtissues enable remote microtissue motion control and assembly as well as targeted differentiation. This study demonstrates accelerated endochondral ossification under magnetic stimulation, highlighting cartilaginous assembloid constructs’ ability to retain long‐term magnetic properties.

Low‐toxicity metal–organic frameworks: Sustainable solutions for versatile applications

Bulletin of the Korean Chemical Society, Volume 46, Issue 3, Page 265-280, March 2025.
Developing low‐toxicity Metal‐organic Frameworks (MOFs) involves challenges related to stability, scalability, and cost‐effectiveness. Research now focuses on improving MOF design to enhance robustness and exploring greener synthesis methods to minimize environmental impact. Abstract The conventional synthesis of metal‐organic framework (MOF) materials

Recent Sociocultural Changes Reverse the Long‐Term Trend of Declining Habitat Availability for Large Wild Mammals in Europe

Diversity and Distributions, Volume 30, Issue 12, December 2024.
ABSTRACT Aim People have strongly influenced the biosphere for millennia, but how their increasing activities have shaped wildlife distribution is incompletely understood. We examined how the distribution of European large (>8 kg), wild mammals has changed in association with changing anthropogenic pressures and climate change through the Holocene ...

Challenges and Support when Introducing AM in HPDC Tooling [PDF]

, 2019
When manufacturing tooling inserts for HPDC (High Pressure Die Casting), several manufacturing steps such as milling, heat treatment, electro discharge machining and finally surface treatment are involved. By instead manufacturing the insert by SLM (Selective laser melting), the process is expected to be quicker and with less material waste compared to
