Carbon dots (C-dots) obtained from D-glucose have attracted great interest because of their properties and as a model for understanding the synthesis process and the origin of photoluminescence in carbon-based nanostructures. Synthesising C-dots under hydrothermal conditions has become one of the most common methods for their preparation. Understanding the details of this process is quite difficult. To tackle this challenge, we have adopted a multi-technique approach in our present work. We have correlated different spectroscopic analyses, such as infrared, Raman, fluorescence, NMR, and UV-Vis, to connect the emissions with specific chemical groups...

BACKGROUND: In the last few years, Mexico adopted public health policies to tackle non-communicable diseases (NCDs), such as front of package nutrition labelling, food marketing restrictions to children, and a soda tax. In parallel, transnational food and beverage industries (F&BIs), their allies, and the government have agreed on public-private partnerships (PPPs) to implement policies or deliver programs. However, research has questioned the benefits of PPPs and exposed its limitations as a suitable mechanism to improve public health...

BACKGROUND: Stroke patients often experience difficulty swallowing. OBJECTIVE: To assist in the improvement of dysphagia symptoms by introducing a novel approach to the treatment of patients with post-stroke aspiration. METHODS: A total of 60 patients with post-stroke aspiration were enrolled and divided into an experimental group (n = 30) and a control group (n = 30). The control group received standard treatment, sham intraoral stimulation, and the Masako maneuver, while the experimental group was administered standard treatment, deep pharyngeal electrical stimulation (DPES), and a modified Masako maneuver...

BACKGROUND: Transoral robotic surgery (TORS) for oropharyngeal malignancy optimizes oncologic outcomes while preserving functionality. This study identifies patterns of functional recovery after TORS with free flap reconstruction (FFR). METHODS: Retrospective cohort study at a tertiary care center of patients with primary oropharyngeal tumors treated with TORS with FFR between 2010 and 2022. Patients were categorized into: adjuvant chemoradiation or radiation, or no adjuvant therapy (NAT)...

INTRODUCTION: This study compared the submental surface electromyography (sEMG) duration and amplitude during dry swallowing between irradiated head and neck cancer (HNC) survivors and age-matched normal individuals. Further, the relationship between submental and infrahyoid sEMG in the irradiated HNC group was explored. METHOD: Forty participants (20 HNC survivors and 20 age-matched normal individuals) participated in this study. The HNC survivors had completed organ preservation cancer treatment (at least 1-month post-treatment)...

PURPOSE: Head and neck cancer (HNC) patients often face difficulties with swallowing, which can be due to the cancer itself or the treatment modalities like radiation therapy. The presentation of HNC can vary between developing and developed countries due to socioeconomic factors. The current study aimed to profile the swallowing function of HNC patients before starting radiation therapy in a tertiary hospital in India. METHOD: This cross-sectional observational study examined patients with HNC who were scheduled for radiation therapy...

Ces nouvelles recommandations incluent, parmi les critères de contrôle de l'asthme, une diminution de la fréquence des symptômes diurnes et de l'utilisation de médicaments pour soulager l'asthme à un maximum de deux fois par semaine...

Résumé:De nombreux articles publiés récemment ont laissé apparaître l'émergence d'un nouveau phénomène dans notre rapport avec la pandémie de COVID-19 : la fatigue pandémique. Ce phénomène suggère l'apparition d'une tendance générale de lassitude face aux mesures sanitaires et à l'état d'urgence devenu permanent. L'objectif de cet article est de replacer cet enjeu dans le contexte de la réalisation d'un projet de recherche portant sur les impacts psychosociaux durant la pandémie...

While the extent of environmental contamination by per- and polyfluoroalkyl substances (PFAS) has mobilized considerable efforts around the globe in recent years, publicly available data on PFAS in Europe were very limited. In an unprecedented experiment of "expert-reviewed journalism" involving 29 journalists and seven scientific advisers, a cross-border collaborative project, the "Forever Pollution Project" (FPP), drew on both scientific methods and investigative journalism techniques such as open-source intelligence (OSINT) and freedom of information (FOI) requests to map contamination across Europe, making public data that previously had existed as "unseen science"...

Three-dimensional (3D) cell assemblies, such as multicellular spheroids, can be powerful biological tools to closely mimic the complexity of cell-cell and cell-matrix interactions in a native-like microenvironment. However, potential applications of large spheroids are limited by the insufficient diffusion of oxygen and nutrients through the spheroids and, thus, result in the formation of a necrotic core. To overcome this drawback, we present a new strategy based on nanoparticle-coated microparticles. In this study, microparticles function as synthetic centers to regulate the diffusion of small molecules, such as oxygen and nutrients, within human mesenchymal stem cell (hMSC) spheroids...

BACKGROUND: Although stroke-related dysphagia has been shown to influence quality of life (QOL), the underlying mechanisms have yet to be uncovered. OBJECTIVE: This study aims to investigate the mediating role of nutritional status and psychological disorders in the relationship between stroke-related dysphagia and QOL in stroke patients and explore the moderating effect of enteral nutrition mode. METHODS: In 2022, A questionnaire survey using stratified random sampling was conducted on 5,322 stroke patients with dysphagia, including Functional Oral Intake Scale (FOIS), Swallowing Quality of Life Questionnaire, Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7) to assess dysphagia, QOL and psychological disorders, respectively, for each participant...

There are increasing efforts to better predict adverse outcomes for idiopathic pulmonary fibrosis (IPF). Our aim was to assess the prognostic potential of ischemia-modified albumin (IMA), an established circulating marker of ischemia and, more recently, oxidative stress, in a cohort of 56 IPF patients recruited between 2015 and 2023 at the University of Sassari, Italy. Demographic and functional parameters and serum IMA concentrations were measured at baseline. Non-survivors had significantly higher IMA concentrations vs...

INTRODUCTION: Inflammatory bowel disease (IBD) is a chronic gastrointestinal disease that is seperated into two types: ulcerative colitis (UC) and Crohn's disease (CD). Although dysphagia is a well-studied and important topic in head and neck cancers and neurological disorders, research on the relationship between IBD and swallowing problems is not yet elucidated. The aim of this study was to compare swallowing function in the UC and CD using objective and patient-reported evaluation modalities...

Filtration media used to quantify particulate and gaseous releases have been collected from Hartlepool Power Station in the United Kingdom and measured using high-sensitivity gamma-spectrometry systems. Radionuclides that are relevant to the monitoring regime of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) have been detected. Results are reported and compared to detections recorded on the International Monitoring System (IMS). Time series activity plots have been produced and results interpreted with respect to known plant activities...

Recent widespread connections of renewable energy resource (RESs) in place of fossil fuel supplies and the adoption of electrical vehicles in place of gasoline-powered vehicles have given birth to a number of new concerns. The control architecture of linked power networks now faces an increasingly pressing challenge: tie-line power fluctuations and reducing frequency deviations. Because of their nature and dependence on external circumstances, RESs are analogous to continually fluctuating power generators. Using a fractional order-based frequency regulator, this work presents a new method for improving the frequency regulation in a two-area interconnected power system...

OBJECTIVE: To assess the correlation between lesion location and swallowing function characteristics in post-stroke dysphagia (PSD) patients. MATERIALS AND METHODS: We enrolled 133 PSD. The patients were divided into supratentorial and infratentorial stroke groups. We compared the measurements in the videofluoroscopic swallowing study (VFSS) with 3ml and 5 ml of diluted and thickened barium liquid data between supratentorial and brainstem stroke groups. We further compared the difference of VFSS measurements between patients with left hemispheric or right hemispheric lesions (further divided into unilateral hemispheric cortical and subcortical subgroups) and brianstem leison stroke group...

Accumulating evidence points to dysregulations of the Nucleus Accumbens (NAc) in eating disorders (ED), however its precise contribution to ED symptomatic dimensions remains unclear. Using chemogenetic manipulations in male mice, we found that activity of dopamine D1 receptor-expressing neurons of the NAc core subregion facilitated effort for a food reward as well as voluntary exercise, but decreased food intake, while D2-expressing neurons have opposite effects. These effects are congruent with D2-neurons being more active than D1-neurons during feeding while it is the opposite during running...

BACKGROUND: Nasogastric tube feeding (NG) has been widely used in patients with bulbar palsy after ischemic stroke but is associated with a significant risk of complications including malnutrition and pneumonia. Intermittent oro-esophageal tube feeding (IOE) can help alleviate these concerns. This study explored the clinical effect of IOE versus NG on nutritional status, swallowing function, stroke-associated pneumonia, and depression in patients with bulbar palsy after ischemic stroke...

Many Astragalus species exhibit seeds with physical dormancy (PY), but little is known about the ecological context of this dormancy. We focused on A. maritimus and A. verrucosus , two threatened Sardinian endemic species inside the subgenus Trimeniaeus Bunge. Fresh seeds collected from the only two respective known populations were used to investigate the effect of mechanical scarification, heat shock, and water imbibition processes on PY release and germination. PY can be overcome through mechanical scarification of the water-impermeable seed coats, while no dormancy break was detected, nor a subsequent increase in seed germination due to fire-induced heat...
