Periodic structures are known to produce passbands and stopbands for propagation of vibration energy within the frequency domain. Sources vibrating harmonically at a frequency within a passband can lead to propagation of energy through propagating modes over long distances. However, sources vibrating at a frequency within a stopband excite only nearfields in the form of attenuating and evanescent
BACKGROUND: A history of preeclampsia is associated with increased risk of coronary artery disease and experimental evidence suggests that a history of preeclampsia also increases the risk of restenosis. However, the extent to which a history of preeclampsia is associated with risk of restenosis after percutaneous coronary intervention in women is unknown. METHODS AND RESULTS: We included 6065 par
False positive recall is a major issue in breast cancer screening and the introduction of artificial intelligence (AI) might affect which women who are unnecessarily recalled. We have investigated how an AI system works on false positive recalls at screening and compared with radiologist findings. Two-view digital mammography (DM) examinations from 656 recalled women (136 with screening detected c
Background: Cervical cancer is a major cause of mortality and morbidity in women worldwide. This study aimed to estimate the association between common urogenital infections and cervical neoplasia. Methods: A multi-register national cohort study of 4,120,557 women aged ≥15 years (2002–2018) was conducted. The outcomes were cervical cancer and carcinoma in situ (Swedish Cancer Register). The main p
Deficiencies of the early complement components of the classical pathway (CP) are well-documented in association with systemic lupus erythematosus (SLE) or SLE-like syndromes and severe pyogenic infections. Among these, complete C1s deficiency has been reported in nine cases so far. Here, we describe a 34-year-old male patient who presented with severe, recurrent infections since childhood, includ
OBJECTIVES: Ultra-high dose rate irradiation (UHDR) has been shown to spare normal tissue in various model systems. This study evaluates its potential to sterilize cancer cells using spheroid tumor models.METHODS: Spheroids from glioblastoma (U87), hypopharyngeal squamous cell carcinoma (two sizes, FaDusmall and FaDularge) and breast adenocarcinoma (T47D) cells were irradiated with electron beams
Background: The Hip disability and Osteoarthritis Outcome Score (HOOS) is a self-administered hip-specific questionnaire intended to evaluate symptoms and functional limitations, and it is commonly used to evaluate interventions in individuals with hip dysfunction or hip osteoarthritis. The HOOS consists of 43 questions in five subscales: Pain, Symptoms, Function in daily living, Function in sport
Tissue clearing allows 3D-imaging of large biomedical samples, but can be affected by blur effects limiting individual cells detection. Using a structured illumination light sheet we solve this issue, obtaining high-contrast images in turbid samples.
Non-lethal infections are common in free-living animals and the associated sickness behaviours can impact crucial life-history trade-offs. However, little is known about the duration and extent of such sickness behaviours in free-living animals, and consequently how they affect life-history decisions. Here, free-living Eurasian blackbirds, Turdus merula, were immune-challenged with lipopolysacchar
Fibre-optic based sensing technologies are becoming popular in the field of geophysics since enable long range and high spatial resolution acoustic measurements. In this work, we present preliminary results obtained using quasi-distributed Fibre-Bragg grating sensing and Distributed Acoustic Sensing (DAS) to monitor seismic activities in an operational underground mine. 12 FBGs and 800 metres of f
A novel photodynamic therapy system based on interstitial illumination using multiple fibres is under development. The aim with this system is to enable treatment of large tumour volumes and also to utilise real-time measurements to allow on-line dosimetry. Important dosimetric parameters to measure are light fluence rate, sensitizer fluorescence intensity and local blood oxygenation. A constructi
Denna uppsats avser att utreda och beskriva förutsättningarna för återvinning av betalning av en skuld enligt 4 kap 10 § KonkL och att belysa hur regleringen brukar tolkas och tillämpas. Syftet är att redogöra för innebörden av bestämmelsens rekvisit, med fördjupning i vad som avses med ordinär betalning och hur det bedöms om en betalning är att anse som ordinär eller ej. Materialet i denna uppsatThis essay intends to investigate and to describe the conditions for recovery of payment of a debt according to chapter 4 § 10 KonkL and to highlight how the regulation is usually interpreted and applied. The purpose is to explain the meaning of the provision's requisites, with an in-depth look at what is meant by ordinary payment and how it is assessed whether a payment is to be regarded as o
Background: Individuals with diabetes (DM) are often treated with statins, which have a rare side effect: peripheral neuropathy. We aimed to study whether statin treatment affects the risk of carpal tunnel syndrome (CTS) and ulnar nerve entrapment (UNE) in type 2 DM (T2DM). Methods: We combined multiple national registers in Sweden to identify individuals diagnosed with CTS or UNE in specialized c

In the female turnip moth, Agrotis segetum, a pheromone biosynthesis activating neuropeptide (PBAN) stimulates sex pheromone biosynthesis which exhibits a daily rhythm. Here we show data supporting a circadian rhythm in PBAN release from the corpora cardiaca, which we propose regulates the endogenous rhythm in sex pheromone biosynthesis. This conclusion is drawn as the observed daily rhythm in PBA
The efficiency with which flying animals convert metabolic power to mechanical power dictates an individual's flight behaviour and energy requirements. Despite the significance of this parameter, we lack empirical data on conversion efficiency for most species as in vivo measurements are notoriously difficult to obtain. Furthermore, conversion efficiency is often assumed to be constant across flig
Many Arctic-breeding animals are at risk from local extirpation associated with habitat constriction and alterations in phenology in their Arctic environment as a result of rapid global warming.1 Migratory species face additional increasing anthropogenic pressures along their migratory routes such as habitat destruction, droughts, creation of barriers, and overexploitation.2,3 Such species can onl
Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an emerging and potentially life-saving procedure, necessitating qualified operators in an increasing number of centres. The procedure shares technical elements with other vascular access procedures using the Seldinger technique, which is mastered by doctors not only in endovascular specialties but also in trauma surg
