This case report highlights the challenges in treating bronchopulmonary dysplasia (BPD) in a premature infant with severe pulmonary hypertension, recurrent pulmonary hypertensive crises, and the need of 100% oxygen to achieve acceptable arterial oxygen saturations. Key factors in the infant's improvement involved switching from pulmonary vasodilation to systemic afterload reduction using losartan,
Biofilms are highly organized, cooperating communities of microorganisms encased in a self-produced extracellular matrix, providing resilience against external stress such as antimicrobial agents and host defenses. A hallmark of biofilms is their phenotypic heterogeneity, which enhances the overall growth and survival of the community. In this study, we demonstrate that removing the dnaK and tig g
There is a strong societal demand for the development of effective and eco-friendly UV blocking substances for sunscreen applications. In this work, three AB2-type monomers with 0-2 methoxy groups are synthesized using three corresponding lignin-based monomeric aromatics and a potentially biobased hydandoin. The obtained AB2-type monomers are conveniently polymerized via conventional bulk polycond
Qualitative and quantitative visualizations of transonic turbomachinery flows provide essential information on compressibility and Mach number effects on boundary layer development, shock-boundary layer interactions, and trailing edge flows. Background oriented Schlieren (BOS) is a relatively new optical technique that allows capturing unsteady density gradient fields through turbomachinery cascad
With incredible speed Large Language Models (LLMs) are reshaping many aspects of society. This has been met with unease by the public, and public discourse is rife with questions about whether LLMs are or might be conscious. Because there is widespread disagreement about consciousness among scientists, any concrete answers that could be offered the public would be contentious. This paper offers th
In recent years, more sophisticated DNA technologies for genotyping have enabled considerable progress in various fields such as clinical genetics, archaeogenetics and forensic genetics. DNA samples previously rejected as too challenging to analyze due to low amounts of degraded DNA can now provide useful information. To increase the chances of success with the new methodologies, it is crucial to
Using Ambient Pressure X-ray Photoelectron Spectroscopy (APXPS), this study investigates the reduction behavior of iron oxides in direct reduction (DRI) and blast furnace (BF) pellets. H2, CO, and a H2–CO mixture are used as reducing agents at 650 °C. The investigation aimed to elucidate variations in the rate of reduction over time and under different conditions. Additionally, contour plots are g
Chiral state transfer along closed loops in the vicinity of an exceptional point is one of the many counterintuitive observations in non-Hermitian physics. The application of this property beyond proof-of-principle in quantum physics, is an open question. In this work, we demonstrate chiral state conversion between singlet and triplet Bell states through fully quantum Liouvillian dynamics. Crucial
Stroke is one of the leading causes of death and disability, yet the cellular response to the ischemic insult is poorly understood limiting therapeutic options. Brain pericytes are crucial for maintaining blood-brain barrier (BBB) integrity and are known to be one of the first responders to ischemic stroke. The exact timeline of cellular events after stroke, however, remains elusive. Using the per
BACKGROUND: Colistin resistance in Acinetobacter baumannii is an emerging problem that limits antimicrobial therapy options.MATERIALS & METHODS: We isolated two pairs of colistin susceptible and colistin-resistant A. baumannii (K1007/K1006 and K408/K409) from two patients diagnosed with carbapenem-resistant A. baumannii infection. Colistin susceptible isolates were exposed to in vitro colistin
BACKGROUND: In the era of rising carbapenem resistance, we aimed to investigate the change in mortality rate and positivity of carbapenemase genes in Acinetobacter baumannii.METHODS: Preferred Reporting Items for Systematic Review (PRISMA) guidelines were adopted in this systematic review. Our literature search included the Cochrane Library, Pubmed, Scopus, Web of Science, Medline, Tubitak TR Dizi
Objective To investigate whether patients with hard-to-heal ulcers in Sweden were treated according to an aetiological diagnosis and to explore ulcer healing, treatment time, ulcer-related pain and the prescription of analgesics and antibiotics. Design A national mapping of data from the patients’ medical records, between April 2021 and March 2023. Setting Data from medical records for patients wi
This research introduces a novel Energy Management approach, named CIRLEM, aiming to enhance the smartness of buildings by focusing on technical systems operations, environmental variations, and occupants' needs. Deployed in a simulated environment using Building Performance Simulation and Python integration, the study evaluates CIRLEM's performance under future extreme cold weather scenarios, emp
Diabetic retinopathy (DR) continues to be the primary cause of vision loss in poorly controlled diabetic subjects. The molecular mechanisms underlying retinal pigment epithelium (RPE) cell dysfunction in DR still remain elusive. We investigated the role of mitochondrial volt-age-dependent anion channel 1 (VDAC1) in RPE dysfunction under glucotoxic and inflammatory conditions. Our results demonstra
Background and objective: Patients diagnosed with grade group (GG) 1 prostate cancer (PCa) following treatment for benign disease (“incidental” PCa) are typically managed with active surveillance (AS). It is not known how their outcomes compare with those observed in patients diagnosed with GG1 on biopsy. We aimed at determining whether long-term oncologic outcomes of AS for patients with GG1 PCa
Effectively identifying deviations in real-world medical time-series data is a critical endeavor, essential for early surveillance of disease outbreaks. This paper demonstrates the integration of time-series anomaly detection techniques to develop surveillance systems for disease outbreaks. Utilizing data from Sweden's telephone counseling service (1177), we first illustrate the trends in physical
