PURPOSE: Magnetization transfer saturation (MTsat ) mapping is commonly used to examine the macromolecular content of brain tissue. This study compared variable flip angle (VFA) T1 mapping against compressed-sensing MP2RAGE (csMP2RAGE) T1 mapping for accelerating MTsat imaging. METHODS: VFA, MP2RAGE, and csMP2RAGE were compared against inversion-recovery T1 in an aqueous phantom at 3 T. The same 1-mm VFA, MP2RAGE, and csMP2RAGE protocols were acquired in 4 healthy subjects to compare T1 and MTsat ...

We evaluated the effect of periosteal-releasing incisions on flap displacement in anterior maxillary sites following implant placement and simultaneously guided bone regeneration. Thirty patients requiring a single dental implant and guided bone regeneration in the maxillary esthetic zone were recruited. After full-thickness flap elevation, the displacement of the flap was measured under a standardized tension of 1 Ncm. Then, a two-step periosteal releasing incision was placed in the internal aspect of the flap, and the displacement was remeasured using the same standardized tension...

Cigarettes with pronounced astringency can diminish consumers' enjoyment. However, due to the complex composition of cigarettes, quantifying astringency intensity accurately has been challenging. To address this, research was conducted to develop a method for assessing astringency intensity in a simulated oral environment. The astringency intensity of four cigarette brands was determined using the standard sensory evaluation method. The mainstream smoke absorbing solution (MS) was prepared by simulating the cigarette smoking process, and its physicochemical properties (such as total phenol content and pH levels) were analyzed...

INTRODUCTION: The Sensory Processing Measure 2 (SPM2) and the Sensory Profile 2 (SP2) are two sensory processing scales often used by occupational therapists. The SPM2 and SP2 both claim to assess aspects of children's sensory processing. This cross-sectional study examined the convergent validity of the SPM2-Home Form (SPM2-HF) and Child SP2 for school-aged neurotypical children. METHODS: Thirty parents/caregivers of neurotypical children aged 7 to 12 completed the SPM2-HF and the Child SP2 about their child...

One challenge confronting the Cu2O catalysts in the electrocatalysis of carbon dioxide reduction reaction (CO2RR) is the reduction of active Cu(I) species, resulting in low selectivity and quick deactivation. In this study, we for the first time introduce a bottom-up growth of convex sphere with adjustable Cu(0)/Cu(I) interfaces (Cux@Cu2O convex spheres). Interestingly, the interfaces are dynamically modulated by varying hydrothermal time, thus regulating the conversion of C1 and C2 products. In particular, the 4 h hydrothermal treatment applied to Cu0...

Far-UVC radiation between 200 and 230 nm is a promising technology for reducing airborne disease transmission. Previous work with far-UVC lamps has demonstrated the efficacy of far-UVC radiation to inactivate bacteria and viruses while presenting minimal human health hazards. While far-UVC intentionally exposes the occupied space, effectively disinfecting air between occupants, installations must still ensure that occupant eye and skin exposure is within the recommended daily limits. This study examines far-UVC-sensitive films for measuring the dose received by occupants within two real-world far-UVC installations...

The incidence of pneumonia has become increasingly prevalent, and its severity has been continuously escalating, bringing significant damage and stress to people's lives. The regulatory role of RP11-773H22.4 in the onset and development of severe pneumonia is emerging as an important factor, however, the exact mechanisms controlling its effects have not been fully elucidated. ROC curve and Kaplan-Meier curve were employed to assess the diagnostic and prognostic significance of RP11-773H22.4 in severe pneumonia...

INTRODUCTION: Microglia are the main phagocytes in the brain and can induce neuroinflammation. Moreover, they are critical to alpha-synuclein (α-syn) aggregation and propagation. Plasma exosomes derived from patients diagnosed with Parkinson's disease (PD-exo) reportedly evoked α-syn aggregation and inflammation in microglia. In turn, microglia internalized and released exosomal α-syn, enhancing α-syn propagation. However, the specific mechanism through which PD-exo influences α-syn degradation remains unknown...

BACKGROUND: Adolescent and young adult (AYA) solid organ transplant (SOT) recipients experience increased rates of rejection and graft loss surrounding the time of health care transition, in part due to poor medication adherence. This study aims to examine the impact of a once-daily formulation of tacrolimus, LCP-tacrolimus (LCPT), on medication adherence for AYA SOT patients. METHODS: A retrospective descriptive analysis was performed for all patients who underwent SOT and were prescribed LCPT after the age of 12 at our single-center pediatric hospital...

BACKGROUND: The optimal enoxaparin dosing for treatment of venous thromboembolism (VTE) in pediatric patients with obesity remains uncertain. We described the mean enoxaparin dose required to attain anti-factor Xa (anti-Xa) levels of 0.5-1 unit/mL in pediatric patients with obesity. METHODS: Pediatric patients with obesity (body mass index [BMI] ≥95th percentile) who received treatment dose of enoxaparin from 2013 to 2022 and had at least one appropriately timed anti-Xa level were retrospectively evaluated...

OBJECTIVE: Cardio-cerebrovascular disease is the major cause of work-related deaths. Salutogenesis indicates individual differences in health levels occur owing to differences in the sense of coherence (SOC). A salutogenesis-based intervention may promote cardio-cerebrovascular health at work. This study examined the effects of a SOC promotion program based on salutogenesis. DESIGN: Quasi-experimental study. SAMPLE: Fifty-six office workers who were above the "low risk" of cardio-cerebrovascular disease from two workplaces were included in the final analysis...

BACKGROUND: High salt intake has been proposed as a risk factor for dementia. However, causal relationship between salt intake and dementia remains uncertain. PURPOSE: The aim of this study was to employ a mendelian randomization (MR) design to investigate the causal impact of salt intake on the risk of dementia. METHODS: Genome-wide association study (GWAS) data of exposures and outcomes (any dementia, cognitive performance, different types of dementia, Alzheimer's disease [AD], and Parkinson's disease) were obtained from the IEU database...

INTRODUCTION: Attention and working memory are key cognitive functions that allow us to select and maintain information in our mind for a short time, being essential for our daily life and, in particular, for learning and academic performance. It has been shown that musical training can improve working memory performance, but it is still unclear if and how the neural mechanisms of working memory and particularly attention are implicated in this process. In this work, we aimed to identify the oscillatory signature of bimodal attention and working memory that contributes to improved working memory in musically trained children...

Sheep (Ovis aries) play an important role in the economy of Turkey and the Balkan Peninsula due to their use in farming. As a domesticated species, sheep's morphometric and morphological diversity is likely determined by selective breeding practices rather than geographic distribution. This study aimed to analyse four different sheep breed skulls and reveal skull asymmetry using geometric morphometric methods. For this purpose, 2D images of 52 sheep skulls from different breeds were analysed from the dorsal view of the skull, using 28 landmarks...

Lipid binding properties of α-synuclein play a central role in protein aggregation and progression of Parkinson's Disease (PD). α-Synuclein, an intrinsically disordered protein, binds to lipid membranes through the formation of two amphipathic helices that insert into the lipid bilayer. All disease-associated single point mutations have been identified to be within these helical regions of α-synuclein: V15A, A30P, E46K, H50Q, G51D, A53T, and A53V. However, the effects of these mutations on the bound states of the two α-helices of the protein have yet to be fully characterized...

Sensing of the biophysical properties of membranes using molecular reporters has recently regained wide-spread attention. This was elicited by the development of new probes of exquisite optical properties and increased performance, combined with developments in fluorescence detection. Here, we report on fluorescence lifetime imaging (FLIM) of various rigid and flexible fluorescent dyes to probe the biophysical properties of synthetic and biological membranes at steady state as well as upon the action of external membrane-modifying agents...

BACKGROUND Histoplasmosis is typically associated with immunocompromised individuals, but cases in immunocompetent patients are rare. Primary cutaneous histoplasmosis (PCH) is a challenging diagnosis due to its clinical polymorphism and can mimic other infectious and non-infectious diseases. Previous cases of PCH have been reported in immunocompetent patients with underlying medical conditions or trauma history. So far there have been no reports of PCH after platelet-rich plasma (PRP) application due to inadequate hygiene measures in an immunocompetent host...

In this research, we synthesized and constructed a novel gelator (named QN ) combining quinoline and naphthalene that self-assembled in N, N-dimethylformamide (DMF) to form a stable supramolecular gel (named OQN ). Under UV light, gel OQN exhibited extremely bright yellow fluorescence. The gel OQN showed excellent sensing performance for both Fe3+ and Cu2+ , with a fluorescence 'turn-off' detection mechanism and the lowest detection limit of 7.58 × 10-8 M and 1.51 × 10-8 M, respectively. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectra, x-ray powder diffraction (XRD), rheological measurements, x-ray photoelectron spectroscopy (XPS), and fluorescence spectroscopy were used to characterize the gel OQN ...
