Imaging of prostate micro-architecture using three-dimensional wide-field optical coherence tomography.

Biomed Opt Express

December 2024

Institute of Physics, Faculty of Physics, Astronomy and Informatics, Nicolaus Copernicus University in Toruń, 5 Grudziądzka St., 87-100 Toruń, Poland.

Prostate cancer is a global health issue that requires new diagnostic methods to provide accurate and precise visualization of prostate tissue on the micro-scale. Such methods have the potential to improve nerve-sparing surgery and to provide image guidance during prostate biopsy. In this feasibility study, we assess the potential of three-dimensional wide-field optical coherence tomography (OCT), covering a volumetric imaging field-of-view up to 46 × 46 × 1 mm, to visualize micro-architecture in 18 freshly excised human prostate specimens.

Adherence to adjuvant endocrine therapy in women with breast cancer is low. We conducted a 24-1 fractional factorial pilot optimization trial to test four intervention components supporting medication adherence [text messages, information leaflet, acceptance and commitment therapy (ACT), self-management website], in the preparation phase of the multiphase optimization strategy. Guided by the National Institute of Health Behavior Change Consortium fidelity framework, we investigated fidelity of design, training, delivery, receipt, and enactment of four intervention components.

Background: Mobile health (mHealth) interventions have the potential to improve health outcomes in low- and middle-income countries (LMICs) by aiding health workers to strengthen service delivery, as well as by helping patients and communities manage and prevent diseases. It is crucial to understand how best to implement mHealth within already burdened health services to maximally improve health outcomes and sustain the intervention in LMICs.

Objective: We aimed to identify key barriers to and facilitators of the implementation of mHealth interventions for infectious diseases in LMICs, drawing on a health systems analysis framework.

Purpose: The Australian Genomics Cardiovascular Disorders Flagship was a national multidisciplinary collaboration. It aimed to investigate the feasibility of genome sequencing (GS) and functional genomics to resolve variants of uncertain significance (VUS) in the clinical management of patients and families with cardiomyopathies, primary arrhythmias, and congenital heart disease (CHD).

Methods: Between April 2019 and December 2021, 600 probands meeting cardiovascular disorder criteria from 17 cardiology and genetics clinics across Australia were enrolled in the Flagship and underwent GS.

The World Health Organization declared COVID-19 to be a public health emergency of international concern on 30 January 2020 and then a pandemic on 11 March 2020. In early 2020, a group of UK scientists volunteered to provide the public with up-to-date and transparent scientific information. The group formed the Independent Scientific Advisory Group for Emergencies (Independent SAGE) and provided live weekly briefings to the public via YouTube.

π-HuB: the proteomic navigator of the human body.

Nature

December 2024

State Key Laboratory of Medical Proteomics, Beijing Proteome Research Center, National Center for Protein Sciences (Beijing), Beijing Institute of Lifeomics, Beijing, China.

The human body contains trillions of cells, classified into specific cell types, with diverse morphologies and functions. In addition, cells of the same type can assume different states within an individual's body during their lifetime. Understanding the complexities of the proteome in the context of a human organism and its many potential states is a necessary requirement to understanding human biology, but these complexities can neither be predicted from the genome, nor have they been systematically measurable with available technologies.

Article Synopsis
  • Successful engineering of vascularized tissues requires incorporating blood capillaries and connecting them to host vessels, which involves arranging endothelial cells to create functional networks.
  • The study compares induced pluripotent stem cell-derived endothelial cells (iPSC-ECs) and primary endothelial cells, finding they perform similarly in forming a capillary-like structure in lab tests.
  • Results indicate that activating certain genes can enhance the tubulogenic activity of iPSC-ECs, supporting their potential use in developing vascularized tissues for therapies.
