Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

Advanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Characterisation of antigen-presenting cells in the murine female reproductive tract and its draining lymph nodes [PDF]

, 2011
Despite the global burden of sexually transmitted diseases, the immunology of the female reproductive tract is poorly understood. An understanding of how the distribution of antigen presenting cells in the tissue and cross talk between cell types both ...

Lung IL-17A-Producing CD4⁺ T Cells Correlate with Protection after Intrapulmonary Vaccination with Differentially Adjuvanted Tuberculosis Vaccines

Vaccines
Tuberculosis (TB), caused by Mycobacterium tuberculosis, results in approximately 1.6 million deaths annually. BCG is the only TB vaccine currently in use and offers only variable protection; however, the development of more effective vaccines is ...

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

Advanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

Lassa fever in African green monkeys: Clinical disease and fatal outcome are associated with systemic viral dissemination and inflammation

Cell Reports Medicine
Summary: Lassa virus (LASV) causes significant human morbidity and mortality in endemic areas of West Africa. Previous studies have shown that cynomolgus macaques of non-Mauritius Asian origin best reproduce clinical features of human Lassa fever (LF ...

LIHNCS - Lugol's iodine in head and neck cancer surgery : a multicentre, randomised controlled trial assessing the effectiveness of Lugol’s iodine to assist excision of moderate dysplasia, severe dysplasia and carcinoma in situ at mucosal resection margins of oral and oropharyngeal squamous cell carcinoma : study protocol for a randomised controlled trial [PDF]

, 2013
Background: Oral cavity and oropharynx cancer are increasing in incidence worldwide but survival outcomes have not significantly improved over the last three decades. The presence of dysplasia or carcinoma in situ at surgical margins following resection
