X-ray methods can offer unique insights into the structural and electronic properties of nanomaterials. Recent years have seen a dramatic improvement in both x-ray sources and x-ray optics, providing unprecedented resolution and sensitivity. These developments are particularly useful for nanowires, which are inherently small and give weak signals. This review gives an overview of how different x-r
BACKGROUND: Statins have been suggested to protect against breast cancer risk, but the observational evidence is inconclusive. We examined the association between statin use and breast cancer incidence among women at higher risk of breast cancer due to a history of benign breast disease (BBD).METHODS: Using Danish registries, we identified cancer-free women aged ≥50 years during 1996-2018 with a h
The main goal of my studies was obtaining bulk acoustofluidic devices able to achieve high energy density inside a water-filled cavity. This led us to explore the interplay of sound and thermal effects more in details. Hence, this thesis covers both thermoacoustic effects in Bulk Acoustic Wave devices and a revisited approach for designing them, focusing on achieving good performance. Thermoacoust
In recent years there has been a renewed interest in the basal forebrain cholinergic system as a target for the treatment of cognitive impairments in patients with Parkinson's disease, due in part to the need to explore novel approaches to treat the cognitive symptoms of the disease and in part to the development of more refined imaging tools that have made it possible to monitor the progressive c
The chemical forms of zinc in fly ash from municipal solid waste incineration (MSWI) crucially affect ash management, influencing both material recovery options and the risk of unwanted leaching into ecosystems. The zinc speciation was investigated in fly ash samples sourced from full-scale MSWI plants, including four grate fired boilers (GB) and one fluidized bed boiler (FB). We applied X-ray Abs
The fundamental energy cost of irreversible computing is given by the Landauer bound of kTln 2 /bit, where k is the Boltzmann constant and T is the temperature in Kelvin. However, this limit is only achievable for infinite-time processes. We here determine the fundamental energy cost of finite-time parallelizable computing within the framework of nonequilibrium thermodynamics. We apply these resul
A photoelectron, emitted due to the absorption of light quanta as described by the photoelectric effect, is often characterized experimentally by a classical quantity, its momentum. However, since the photoelectron is a quantum object, its rigorous characterization requires the reconstruction of the complete quantum state, the photoelectron’s density matrix. Here we use quantum-state tomography to
Radiolabeled targeting agents have emerged as valuable tools for the treatment of disseminated cancer. Monoclonal antibodies (mAbs) are widely employed as carriers for diagnostic and therapeutic radionuclides due to their exceptional specificity and affinity. However, their prolonged circulatory half-life can diminish diagnostic efficacy and increase radiation exposure to non-target tissues in the
Solar drying technologies have emerged as efficient and user-friendly solutions for food drying processes, particularly in regions with limited access to electricity and high post-harvest losses. These technologies offer a sustainable alternative to conventional drying methods. However, one of the key challenges limiting their effectiveness is the non-homogeneous airflow inside the drying chamber,
The emission spectra from the ablation of airborne alumina nanoparticles by a 532 nm nanosecond pulsed laser are investigated to clarify the underlying mechanism and the applicability of different laser diagnostic techniques such as the laser-induced incandescence (LII) and the laser-induced breakdown spectroscopy (LIBS). The particles were observed to be completely ablated above the laser fluence
Surface-enhanced Raman scattering (SERS) technology can detect molecular information; Because of its high sensitivity, it is widely used in chemical analysis. In this study discussed the experimental detection of 1,4-diethynylbenzene molecule based on SERS technology. The SERS spectra of 1,4-diethynylbenzene molecule were calculated by Density Functional Theory (DFT) simulation, and the results sh
Patients diagnosed with psychogenic pseudosyncope reported significantly higher rates of supine syncope, syncopal episodes and traumatic falls than patients diagnosed with vasovagal syncope in a survey questionnaire completed before head-up tilt test.
As the field of neural organoids and assembloids expands, there is an emergent need for guidance and advice on designing, conducting and reporting experiments to increase the reproducibility and utility of these models. In this Perspective, we present a framework for the experimental process that encompasses ensuring the quality and integrity of human pluripotent stem cells, characterizing and man
IMPORTANCE Adherence to the Mediterranean Diet (MedDiet) has been associated with a lower incidence of cancer and reduced weight gain. These associations suggest a potential role for the MedDiet in lowering the risk of obesity-related cancers (ORCs). Obesity is a known risk factor for various cancers and shows an inverse association with MedDiet adherence. OBJECTIVE To examine the association betw
INTRODUCTION: Trust in healthcare is central to the delivery of care and unequally distributed between groups in society. Experiences of perceived discrimination have been associated with lack of such trust. Although the importance of trust in healthcare has been highlighted in recent years, studies in this area are relatively scarce.MATERIALS AND METHODS: We investigated the risk of low trust in
Introduction: Acinetobacter baumannii is a gram-negative opportunistic bacterium that causes life-threatening infections in immunocompromised hosts. The complement system is a critical mechanism of innate immunity that protects the human body from bacterial infections. Complement activation leads to the deposition of the membrane attack complex (MAC), which can directly lyse gramnegative bacteria.
Metastatic castration-resistant prostate cancer (mCRPC) is a heterogeneous disease. Several studies have identified transcriptional subtypes of mCRPC, but comprehensive analysis of prognostic gene expression pathways has been limited. Therefore, we aggregated a cohort of 1012 mCRPC tissue samples from 769 patients and investigated the association of gene expression-based pathways with clinical out
Bakgrund: Pes Equino Varus Adductus (PEVA), även känt som klumpfot, är en medfödd felställning i fotens leder som kräver omfattande behandling under flera år. Det finns ett fåtal studier om hur PEVA påverkar barns grovmotoriska utveckling. Mer kunskap behövs om vilka faktorer som eventuellt kan påverka den grovmotoriska utvecklingen. Syfte: Att beskriva och jämföra utveckling av grovmotorik och pa
