Introduction: Unscheduled return visits to the Emergency Department within 72 hours are widely used as a quality indicator for Medical Services (EMS). Timely identification of predictors patient’s and addressing them during first EMS encounter could minimize potential by triggering attentive, extended, alternate, focused care before discharging patient home. Methods: A retrospective case–control study return-to-EMS cases was conducted at XXXX using data patients above age 15 who visited...
Spontaneous low-frequency Blood-Oxygenation Level-Dependent (BOLD) signals acquired during resting state are characterized by spatial patterns of synchronous fluctuations, ultimately leading to the identification robust brain networks. The resting-state networks, including Default Mode Network (DMN), demonstrated persist sustained task execution, but exact features task-related changes network properties still not well characterized. In this work we sought examine in a group 20 healthy...
Brain activity at rest is characterized by widely distributed and spatially specific patterns of synchronized low-frequency blood-oxygenation level-dependent (BOLD) fluctuations, which correspond to physiologically relevant brain networks. This network behaviour known persist also during task execution, yet the details underlying task-associated modulations within- between-network connectivity are largely unknown. In this study we exploited a multi-parametric multi-scale approach investigate...
Prodigiosin (PDG) is a bacterial metabolite with numerous biological and pharmaceutical properties. Exposure to aluminium considered root etiological factor in the pathological progress of Alzheimer's disease (AD). Here, this investigation, we explored neuroprotective potential PDG against chloride (AlCl3 )-mediated AD-like neurological alterations rats. For purpose, rats were gavaged either AlCl3 (100 mg/kg), (300 or both for 42 days. As result analyzes performed on hippocampal tissue, it...
Spontaneous oscillations of the Blood Oxygenation Level-Dependent (BOLD) signal are spatially synchronized within specific brain networks and thought to reflect activity. Networks modulated by performance a task, even if exact features degree such modulations still elusive. The presence showing anticorrelated fluctuations lend initially suppose that competitive relationship between default mode network task positive supports efficiency processing. However, more recent results indicate...
A new model based on a series of mathematical functions for estimating excretion rates following the intake nine different radionuclides is presented in this work. The under investigation are: cobalt, iodine, cesium, strontium, ruthenium, radium, thorium, plutonium, and uranium. committed effective dose has been calculated by our so as to obtain urinary faecal each radionuclide. said further validated comparison with widely spread Mondal software simulation program. results obtained show...
The objective of this paper is to assess the radiation exposure resulting from radioactive patients injected with different activities 2-[18F] fluoro-2-deoxy-D-glucose (18F-FDG) in Positron Emission Tomography/Computed Tomography (PET/CT) units. This fulfilled by measuring dose rates practically inside and outside PET/CT rooms around using a calibrated survey meter. Afterwards, are estimated mathematically Monte Carlo simulation model. results show that on patient's body surface decrease...

In this study, Abu Tartur open-pit Phosphate mine and underground tunnels have been studied from radiation safety point of view.Radon, radon daughters thoron were measured by collecting (31) samples (5) main sites that represent the process mining.Results radon, daughters, in case mining ranged 1.37 to 131.52 Bq m-3, 0.000099 0.0024 WL, 0 0.92 Bq.m-3 respectively.For postpone tunnels, results 411.55 2539.27Bq 0.056 0.37 1.26 3.89 respectively.Also, gamma levels, surface contamination...
The main property required of metallic biomaterials such as Titanium foam for biomedical applications is to be a biocompatible material.Good mechanical properties, osseointegration, high corrosion resistance, and excellent wear resistance are required.Furthermore, it crucial improving the biological properties highly porous structure titanium foams implant materials dental implants.Owing its outstanding low density, chemical titanium-based have various promising applications.This paper aims...
