Background: Despite improvement of lung preservation by the introduction of low-potassium dextran (LPD) solution, ischemia-reperfusion injury remains a major contributor to early post-lung transplant graft dysfunction and mortality. After favorable experimental data, Celsior solution was used in our clinical lung transplant program. Data were compared with our historic LPD cohort.
Methods: Between January 2002 and January 2005, 209 consecutive lung transplantations were performed with LPD. These were compared to 208 transplants between February 2005 and September 2007 with Celsior. Endpoints included posttransplant PaO2/FiO2 ratio at different timepoints after intensive care unit (ICU) admission, posttransplant ventilation time, ICU stay and 30-day mortality, follow-up survival, and bronchiolitis obliterans syndrome-free survival.
Results: Ratios of sex, urgency status, type of procedure, length of posttransplant ICU stay, and age did not show significant differences between the 2 groups. Mean ischemia times were significantly longer in the Celsior group (LPD, 355 ± 105 minutes vs Celsior, 436 ± 139 minutes, P < 0.001). Overall 3-year-survival (LPD, 66.5% vs Celsior, 72.0%; P = 0.25) was nonsignificantly improved in the Celsior cohort.
Conclusions: A trend toward better survival (P = 0.09) and increased freedom from bronchiolitis obliterans syndrome (P = 0.03) was observed in the Celsior group despite prolonged ischemic times compared with LPD. Lung preservation with Celsior is safe and effective and may carry advantages.

An optimal administration approach is critical for effective mRNA delivery and treatment. Nebulizer inhalation offers a mild, convenient, and noninvasive strategy with high translational potential but primarily focused on lung delivery. In this study, we found that surface charges influence tissue targeting of mRNA lipid nanoparticle (mRNA-LNP) postnebulization.

Chemical imaging holds great promise for chemical, materials, and biological applications. However, its contrast often relies on subtle spectral differences arising from molecular-level changes. Here, we introduce label-free chemical imaging based on bond-specific coherent interference, which is highly sensitive to nanoscopic structural variations in collagen fibers.

Purpose: The accuracy of oral microbiome research depends significantly on specimen sampling protocols, as well as their storage and preservation. Traditional methods, such as freezing, may not only involve logistical hurdles but can also impact the quality of microbial data, leading to difficulties in the comparability between different studies. This study evaluates the effectiveness of the room temperature nucleic acid preservation protocol using DNA/RNA Shield buffer as compared to standard freezing in preserving oral microbial communities over the course of 7 days.

Some patients with heart failure with preserved ejection fraction (HFpEF) have demonstrated evidence of exercise-induced arterial hypoxaemia (EIAH). However, EIAH was not quantified using , , and measurements as previously conducted in healthy adults nor was EIAH quantified alongside simultaneous measurements of pulmonary vascular pressures, cardiorespiratory responses, or dyspnoea on exertion (DOE) in these patients. Given the effects of hypoxaemia on pulmonary vasoconstriction, cardiorespiratory responses, and DOE, we tested the hypothesis that patients with HFpEF and EIAH (EIAH) would demonstrate higher pulmonary vascular pressures, worse oxygen uptake, and greater DOE compared with patients without EIAH (EIAH).

Thoracic surgeons utilizing minimally invasive techniques for lung nodule resection often rely on localization markers to determine precise nodule location intraoperatively. Transbronchial or transthoracic injection of indocyanine green (ICG) dye has become a popular technique. However, surgery must be performed immediately as dye will dissipate to surrounding tissue.
