Chemotactic Factors in Bronchial Secretions of Cystic Fibrosis Patients [PDF]

, 2017
To understand chronic neutrophil attraction into cystic fibrosis airways, both global chemotactic activity and individual chemotactic factors were studied in bronchial secretions. Bronchial secretions of 8 cystic fibrosis patients, collected on the first

Bone Healing Around Implants in Normal and Medically Compromised Conditions: Osteoporosis and Diabetes

Advanced Healthcare Materials, EarlyView.
xx xx. ABSTRACT Osseointegration of orthopedic and dental implants is influenced by local and systemic factors, including their physicochemical surface properties and the patient's overall health status. Titanium and its alloys have been a longstanding standard for bone implants due to their innate biocompatibility and mechanical properties.

siRNA Delivery via Cross‐Linked Gelatin Microparticles Enables Targeted Modulation of Osteogenic‐Vascular Cross‐Talk: An Advanced Human 3D in Vitro Test System for Therapeutic siRNA

Advanced Healthcare Materials, EarlyView.
Osteogenic‐angiogenic cross‐talk is a vital prerequisite for vascularized bone regeneration. In this study, we investigated the effects of siRNA‐mediated silencing of two inhibitory proteins, Chordin and WWP‐1, via CaP‐NP‐loaded gelatin microparticles in osteogenically differentiated microtissues.

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Multimodal Actuation and Environment Adaptive Strategies of Bio‐Inspired Micro/Nanorobots in Precision Medicine

Advanced Robotics Research, EarlyView.
An introduction for multidrive and environment‐adaptive micro/nanorobotics: design and fabrication strategies, intelligent actuation, and their applications. Various intelligent actuation approaches—magnetic, acoustic, optical, chemical, and biological—can be synergistically designed to enhance flexibility and adaptive behavior for precision medicine ...

Phosphatidic acid-dependent localization and basal de-phosphorylation of RA-GEFs regulate lymphocyte trafficking

BMC Biology, 2020
Background Lymphocytes circulate between peripheral lymphoid tissues via blood and lymphatic systems, and chemokine-induced migration is important in trafficking lymphocytes to distant sites.

Substantially Altered Local and Systemic Immunity in Ischemia‐Free Versus Conventional Liver Transplantation

Advanced Science, EarlyView.
This study investigates how ischemia‐free liver transplantation (IFLT) shapes both local and systemic immune responses compared with conventional liver transplantation (CLT). Our findings demonstrate that IFLT confers significant immunological protection by attenuating the STAT3‐HIF‐1α axis and enhancing the Heme‐HMOX1 pathway, two regulatory networks ...

Tumor growth instability and the onset of invasion

, 2005
Motivated by experimental observations, we develop a mathematical model of chemotactically directed tumor growth. We present an analytical study of the model as well as a numerical one.

Hypoxic pre-conditioning increases the infiltration of endothelial cells into scaffolds for dermal regeneration pre-seeded with mesenchymal stem cells. [PDF]

, 2015
Many therapies using mesenchymal stem cells (MSC) rely on their ability to produce and release paracrine signals with chemotactic and pro-angiogenic activity.
