Coating biological membranes onto biomimetic nanocarriers improves biocompatibility, prolongs circulation, and enhances targeted delivery for cancer precision medicine. To better understand the biodistribution profiles of these biomimetic nanosystems, molecular imaging techniques, including optical imaging, radionuclide imaging, magnetic resonance imaging, and ultrasound imaging, have been widely employed for in vivo tracking and dynamic imaging. Here in this review, we delve into the profound role of these imaging modalities in visualizing changes in the tumor microenvironment, particularly in monitoring oxygen consumption and immune response dynamics, highlighting their potential to improve cancer therapies.

Background: Cardiopulmonary exercise testing (CPET) is usually considered the gold standard for assessing maximal oxygen consumption (V̇O), a health and performance marker in patients with chronic obstructive pulmonary disease (COPD). Despite the widespread application of CPET, the absolute and relative test-retest reliability of CPET-derived metrics remains unexamined.
Objective: To examine and compare test-retest reliability of CPET derived metrics in individuals with COPD and healthy matched controls.
Physiological arterial pressure improves renal performance during normothermic machine perfusion in a porcine kidney DCD model.

Background: Normothermic machine perfusion (NMP) provides a platform for kidney quality assessment. Donation after circulatory death (DCD) donor kidneys are associated with great ischemic injury and high intrarenal resistance (IRR). This experimental study aims to investigate the impact of different perfusion pressures on marginal kidney function and injury during NMP.

Cisplatin (CP) is a first-line platinum-based drug used for the treatment of head and neck cancer. However, tumor cells can diminish the therapeutic effects of CP through the detoxification system mediated by glutathione (GSH) and the nucleotide excision repair (NER) pathway. Herein, we present a light-activable and pH-responsive oxidative stress nanoamplifier (FPLC@IR OSNA), comprising an amphiphilic compound (FPLC) with Fmoc-lysine acting as a connector between a nitroimidazole derivative and a pH-responsive cinnamaldehyde (CA) derivative, loaded with photosensitizer IR780.

Background: Workplace health screening rarely includes measures of cardiorespiratory fitness, despite it being a greater predictor of cardiovascular disease and all-cause mortality than other routinely measured risk factors. This study aimed to determine the comparative acceptability of using a novel seismocardiography device to measure cardiorespiratory fitness via VO max during a workplace health check.
Methods: Participants were invited to participate in workplace health screening sessions where VO max was assessed by both seismocardiography at rest and sub-maximal exercise testing, in order for acceptability of both to be compared across multiple domains.
