[Potassium role in the human body and clinical implications of hyperkalemia].

Potassium is the most represented intracellular electrolyte in the human body. Its extracellular levels are maintained within strict limits through different mechanisms, which constitute the homeostasis of potassium. Hyperkalemia is the most common electrolyte disorder in patients with cardiovascular disease.

Development of a multi-layer high-efficiency GEM-based neutron detector for spallation sources.

Neutron detection is nowadays mostly based on He gas detectors, but its shortage and the continuous upgrades of the neutron facilities require new devices to perform experiments with maximum performances. This work presents a new detector based on the Gas Electron Multiplier (GEM) combined with several boron layers. This detector combines the features of GEM technology with the properties of boron as a neutron converter and the device is produced to sustain high neutron fluxes with high detection efficiency.

Emotion in action: A study on the enactment effect on emotional action sentences.

While abundant literature suggests that both performing congruent actions and emotional stimuli can enhance memory, their combined impact on memory for action phrases remains underexplored. This study investigated the effects of enactment with emotionally charged stimuli on memory performance. Sixty participants encoded action sentences with negative, neutral, or positive emotional connotations using either enactment or verbal-reading methods.

Optimizing leapover lengths of Lévy flights with resetting.

We consider a one-dimensional search process under stochastic resetting conditions. A target is located at b≥0 and a searcher, starting from the origin, performs a discrete-time random walk with independent jumps drawn from a heavy-tailed distribution. Before each jump, there is a given probability r of restarting the walk from the initial position.

[Substance abuse and cardiovascular risk: energy drinks].

The consumption of energy drinks (ED) has become a growing public health issue, since potentially ED-related serious adverse cardiovascular events, including arrhythmias, myocardial infarction, cardiomyopathies, and sudden cardiac death, have been reported in recent years. The substances contained in ED include caffeine, taurine, sugars, B group vitamins and phyto-derivatives, which, especially if taken in large quantities and in a short amount of time, could cause serious side effects through various mechanisms of action, such as increased blood pressure and QT interval prolongation. Although there are still many open questions on ED that require further specific investigations, there is an urgent need for information and educational plans to the population, as well as for regulatory actions, particularly regarding transparency of substances and possible adverse effects.

Evaluating well-being and psychosocial risks in academia: Is management the "forgotten phase"?

In recent years, there has been a noticeable increase in attention towards promoting well-being within academic settings. In the specific context of academia, a critical issue is understanding whether the current practices for assessing and managing well-being can bridge the implementation gap and increase opportunities for creating healthy academic conditions. The paper explores the practices adopted for assessing and managing work-related stress (WRS) risks in Italian academia by referring to data from a group of Italian universities of the QoL@Work network (Quality of Life at Work in academia).

Embodied Spatial Navigation Training in Mild Cognitive Impairment: A Proof-of-Concept Trial.

Background: Egocentric and allocentric spatial memory impairments affect the navigation abilities of older adults with mild cognitive impairment (MCI). Embodied cognition research hints that specific aids can be implemented into virtual reality (VR) training to enhance spatial memory.

Objective: In this study, we preliminarily tested 'ANTaging', an embodied-based immersive VR training for egocentric and allocentric memory, compared to treatment as usual (TAU) spatial training in MCI.

On the Origin of the Light Yield Enhancement in Polymeric Composite Scintillators Loaded with Dense Nanoparticles.

Fast emitting polymeric scintillators are requested in advanced applications where high speed detectors with a large signal-to-noise ratio are needed. However, their low density implies a weak stopping power of high energy radiation and thus a limited light output and sensitivity. To enhance their performance, polymeric scintillators can be loaded with dense nanoparticles (NPs).

Masked Translation Priming Effects for Chinese-English-Japanese Triple Cognates in Lexical Decision Tasks.

Previous research has demonstrated cognate translation priming effects in masked priming lexical decision tasks (LDTs) even when a bilingual's two languages have different scripts. Because those effect sizes are normally larger than with noncognates, the effects have been partially attributed to the impact of prime-target phonological similarity. The present research extended that work by examining priming effects when using triple different-script cognates, i.

Bodily and Visual-Cognitive Navigation Aids to Enhance Spatial Recall in Mild Cognitive Impairment.

Background: Individuals with mild cognitive impairment (MCI) syndrome often report navigation difficulties, accompanied by impairments in egocentric and allocentric spatial memory. However, studies have shown that both bodily (e.g.

CT Arthrography of the Elbow: What Radiologists Should Know.

Computed tomography (CT) arthrography is a quickly available imaging modality to investigate elbow disorders. Its excellent spatial resolution enables the detection of subtle pathologic changes of intra-articular structures, which makes this technique extremely valuable in a joint with very tiny chondral layers and complex anatomy of articular capsule and ligaments. Radiation exposure has been widely decreased with the novel CT scanners, thereby increasing the indications of this examination.

Hemodynamic evaluation in preterm infants using ultrasonic cardiac output monitor (USCOM).

We aimed to establish reference ranges for USCOM parameters in preterm infants, determine factors that affect cardiac output, and evaluate the measurement repeatability. This retro-prospective study was performed at Fondazione IRCCS San Gerardo dei Tintori, Monza, Italy. We included infants below 32 weeks of gestational age (GA) and/or 1500 g of birth weight (BW).

[Lipoprotein(a): relationships with atherosclerosis and valvular heart disease, and emerging therapies].

Lipoprotein(a) [Lp(a)] is a well-established cardiovascular risk factor, whose relationship with atherosclerotic disease has been confirmed by epidemiological, genome-wide association, Mendelian randomization, and meta-analysis studies. This association is determined by its pro-atherogenic, pro-thrombotic and pro-inflammatory properties. Lp(a) is the most common monogenic risk factor for atherosclerosis, with a prevalence of about 1 in 5 people.

A comparison of visual assessment and semi-quantification for the diagnostic and prognostic use of [F]flortaucipir PET in a memory clinic cohort.

Purpose: [F]Flortaucipir PET is a powerful diagnostic and prognostic tool for Alzheimer's disease (AD). Tau status definition is mainly based in the literature on semi-quantitative measures while in clinical settings visual assessment is usually preferred. We compared visual assessment with established semi-quantitative measures to classify subjects and predict the risk of cognitive decline in a memory clinic population.

Genomic instability analysis in DNA from Papanicolaou test provides proof-of-principle early diagnosis of high-grade serous ovarian cancer.

Late diagnosis and the lack of screening methods for early detection define high-grade serous ovarian cancer (HGSOC) as the gynecological malignancy with the highest mortality rate. In the work presented here, we investigated a retrospective and multicentric cohort of 250 archival Papanicolaou (Pap) test smears collected during routine gynecological screening. Samples were taken at different time points (from 1 month to 13.

The effect of visual perspective on episodic memory in aging: A virtual reality study.

The possibility of flexibly retrieving our memories using a first-person or a third-person perspective (1PP or 3PP) has been extensively investigated in episodic memory research. Here, we used a Virtual Reality-based paradigm to manipulate the visual perspective used during the encoding stage to investigate age-related differences in the formation of memories experienced from 1PP vs. 3PP.
