Background and purpose: Few studies on magnetic resonance imaging (MRI) only head and neck radiation treatment planning exist, and none using a generally available software. The aim of this study was to evaluate the accuracy of absorbed dose for head and neck synthetic computed tomography data (sCT) generated by a commercial convolutional neural network-based algorithm. Materials and methods: For
Background: The pathophysiology of neurodegeneration is complex. Its diagnosis requires an early identification of sequential changes in several hallmarks in the brains of affected subjects. The presence of brain pathology can be visualized in the cerebrospinal fluid (CSF) by protein profiling. It is clear that the field of Alzheimer’s disease (AD) will benefit from an integration of algorithms in
Background: Nephrolithiasis (NL) is known to be associated with gout, although there are few comparative studies on risk and risk factors for NL in gout compared to population cohorts. In this cohort study we investigated: (1) overall incidence of NL in gout (cases) and general population controls; (2) risk and risk factors (common comorbidities and medications) for first-time NL in cases and cont
Thioredoxin (Trx)-1 is a small, ubiquitously expressed redox-active protein with known important cytosolic functions. However, Trx1 is also upregulated in response to various stress stimuli, is found both at the cell surface and secreted into plasma, and has known anti-inflammatory and antiapoptotic properties. Previous animal studies have demonstrated that exogenous Trx1 delivery can have therape
Multimodal: Gold nanorods are coated with silica/polymer mutilayers, doped with surface-enhance Raman scattering (SERS) and fluorescence agents as well as photosensitizers. The structural and optical properties are tunable and stable in solutions and in living bodies. A real-time and specific in vivo SERS and fluorescence detection method using this structure is applied for tumor detection and sub
Background and Objective: Several investigations indicated that laser Doppler flowmetry on the liver surface reflects relative changes of the total liver blood flow. In this study, Laser Doppler Perfusion Imaging (LDI), monitoring the surface only, was used for measurements of tissue perfusion of normal and/or impaired liver, pancreas, spleen, stomach and intestine, and the blood flow of hepatic t
The marriage squeeze in China, whereby the sex ratio imbalance leaves many males without a marriage partner, is not only about numbers, but also about how the institution of marriage is socially, economically, and politically underpinned. This paper uses the concept of ecology of choice in mate selection to demonstrate how different social processes and practices have ramifications on who can marr
Aim: To present gender-specific normative data on estimates of neuromuscular performance, such as muscle strength, vertical jump and standing unilateral balance, in pre-pubertal children. Methods: Lean body mass (kg) and fat mass (%) were estimated by dual-energy X-ray absorptiometry in 246 boys and 190 girls aged 6-12 years in Tanner stages 1 and 2. Isokinetic concentric peak torque at 60 and 180
Background: Alcohol use disorder (AUD) is associated with an enormous burden of disease and cost to society. The dopamine deficiency hypothesis posits that negative reinforcement generated by a low brain dopamine state drives ethanol intake. Here, we evaluated the efficacy and safety of combined administration of two dopamine-enhancing drugs, varenicline (a partial nicotinic acetylcholine receptor
Context. HR 10 has only recently been identified as a binary system. Previously thought to be an A-type shell star, it appears that both components are fast-rotating A-type stars, each presenting a circumstellar envelope. Although showing complex photometric variability, spectroscopic observations of the metallic absorption lines reveal variation explained by the binarity, but not indicative of de
Wood's flammability, low dimensional stability, and poor fungal resistance limit its application. In this study, Scots pine sapwood (Pinus sylvestris L.) was treated with a low-molecular-weight phenol–formaldehyde (PF) resin and a monoguanidine phosphate flame retardant (FR) to achieve multifunctional enhancement. Differential scanning calorimetry confirmed no interference of FR with PF curing, wh
BackgroundEarly detection of cerebral palsy (CP) is essential to initiate timely intervention andimprove long-term outcomes for infants at risk. The General MovementsAssessment (GMA) is a well-established tool for early identification of CP, yet itsimplementation in routine clinical practice faces challenges related to access andscalability.AimThis thesis explores the use of GMA as a screening too
Background: Neoadjuvant cisplatin-based combination chemotherapy (NAC) is standard perioperative treatment of patients with muscle-invasive urothelial bladder cancer (MIBC); however, about half of the patients experience recurrence of the disease. Biomarkers for response and survival represent an unmet medical need. We used tumor specimens from transurethral resections of the bladder to explore ge
Galectin-3 is a beta-galactoside-binding mammalian lectin that is one of a 15-member galectin family that can bind several cell surface glycoproteins via its carbohydrate recognition domain (CRD). As a result, it can influence a range of cellular processes including cell activation, adhesion and apoptosis. Galectin-3 has been implicated in various diseases, including fibrotic disorders and cancer,
Permafrost-affected ecosystems are subject to warming and thawing, which can increase the availability of subsurface nitrogen (N) with consequences in otherwise N-limited tundra and alpine vegetation. Here, we quantify the extent of warming and permafrost thawing and the corresponding effects on nitrogen availability and plant growth based on a 20-year survey across 14 sites on the Tibetan Plateau
Research on the impacts of COVID-19 on mobility has focused primarily on the increased health vulnerabilities of involuntary migrant and displaced populations. But virtually all migration flows have been truncated and altered because of reduced economic and mobility opportunities of migrants. Here we use a well-established framework of migration decision-making, whereby individual decisions combin
Although temporal conceptualizations of motivational processes have not held center stage in motivation science, the situation is currently changing. Drawing on work in the subfield of language learning motivation, where the motivational endurance needed to master a second language has been a major concern, the aim of this article is to contribute to the body of work currently exploring motivation
