OBJECTIVE: We evaluated the efficacy of diffusion-weighted magnetic resonance imaging (DW-MRI) in detecting perioperative cerebral thromboembolic events after anterior cervical discectomy and fusion (ACDF). METHODS: This retrospective case series included 51 consecutive patients that underwent ACDF. To assess baseline presence of plaque or stenosis, all patients were assessed for risk factors of cerebrovascular events and underwent carotid ultrasound preoperatively and cerebral DW-MRI was performed in all patients postoperatively, with areas of high signal intensity interpreted as a cerebral thromboembolic event...

BACKGROUND: The 6-minute walk test (6MWT) is a simple functional test that can predict exercise capacity and is widely employed to assess treatment outcomes. Although mortality with transcatheter mitral valve repair (TMVr) using the MitraClip (Abbott Vascular, Menlo Park, CA) is significantly less than for open mitral valve surgery in high-risk patients, identifying which patient will benefit the most from TMVr remains a concern. There are limited prognostic metrics guiding patient selection and, no studies have reported relationship between prolonged hospitalization and 6MWT...

BACKGROUND: Compressed-sensing (CS) accelerated 3D MR cholangiopancreatography (MRCP) could be acquired in both navigator-triggered (NT) and breath-hold (BH) mode, but the latter has been considered inferior in depicting pancreatic duct and diagnosing pancreatic duct-related diseases. PURPOSE: To prospectively evaluate the clinical feasibility of a modified 3D BH-CS-MRCP prototype protocol with small field-of-view (FOV) and higher spatial resolution, and to compare its performance to the original BH-CS-MRCP and NT-CS-MRCP...

BACKGROUND: Recovery after colonic surgery is invariably delayed by disturbed gut motility. It is commonly assumed that colonic motility becomes quiescent after surgery, but this hypothesis has not been evaluated rigorously. This study quantified colonic motility through the early postoperative period using high-resolution colonic manometry. METHODS: Fibre-optic colonic manometry was performed continuously before, during and after surgery in the left colon and rectum of patients undergoing right hemicolectomy, and in healthy controls...

The selective preparation of monoalkylglyceryl ethers (MAGEs) is an active task of research due to their broad range of applications. In this work, green feedstocks such as glycidol and alcohols were used to prepare MAGEs under mild reaction conditions (80°C, 3h, 0.5% in moles of catalyst) in the presence of acid heterogeneous catalysts. Nafion shows the best performances in terms of conversion and selectivity to MAGES and also high stability. A comparison of the environmental performances with the most consolidated pathway from glycerol has shown that the usage of glycidol (recovered as value-added product from Epicerol® process) and Nafion leads to lower impacts on ecosystems...

PURPOSE: To introduce and evaluate an image registration technique for robust quantification of CEST acquisitions corrupted by motion. METHODS: The proposed iterative algorithm exploits a low-rank approximation of the z-spectrum (LRAZ), to gradually separate the contrast variation due to saturation at different off-resonance frequencies and accompanying motion. This registration method was first tested in a creatine CEST analysis of a phantom with simulated rigid motion...

Ever-increasing freshwater scarcity and energy crisis problems require efficient saltwater desalination and energy storage technologies. However, the both targets are generally considered separately. Herein, a hybrid sodium-ion supercapacitor, involving a carbon-coated nano-NaTi2(PO4)3 based battery-anode and an activated carbon based capacitive-cathode, is developed to simultaneously realize above targets. On charge, the supercapacitor removes salt in flowing saltwater electrolyte through Cl- electrochemical adsorption in cathode and Na+-intercalation in anode...

BACKGROUND: Blood group phenotype variation has been attributed to potential resistance to pathogen invasion. Variation was mapped in blood donors from Lampang (northern region) and Saraburi (central region), Thailand, where malaria is endemic. The previously unknown blood group allele profiles were characterized and the data were correlated with phenotypes. The high incidence of the Vel-negative phenotype previously reported in Thais was investigated. STUDY DESIGN AND METHODS: DNA from 396 blood donors was analyzed by matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry...

Understanding implementation of interventions is critical to illuminate if, how, and why the interventions achieve impact. Alive & Thrive integrated a nutrition intervention into an existing maternal, neonatal, and child health (MNCH) programme in Bangladesh, documenting improvements in women's micronutrient supplement intake and dietary diversity. Here, we examined how well the nutrition intervention was implemented and which elements of implementation explained intervention impact. Survey data were collected in 2015 and 2016 from frontline health workers (FLW) and households in areas randomized to nutrition-focused MNCH (intensified interpersonal counselling, community mobilization, distribution of free micronutrient supplements, and weight-gain monitoring) or standard MNCH (antenatal care with standard nutrition counselling)...

The effects of end group and molecular weight on the yellowness of telechelic polyetherimide (PEI) are investigated. Electron-withdrawing dianhydride end groups reduce the yellowness and increase the transparency of PEI regardless of the molecular weight. Electron-donating phenyl, amine, and phthalic end groups increase the yellowness of PEI but the effect depends on the molecular weight. As the molecular weight is increased, the yellowness of PEIs with electron-donating end groups initially decreases due to a decreasing end-group density and then increases due to an increasing probability of charge-transfer complex formation...

Non-alcoholic fatty liver disease (NAFLD)-like conditions enhance the production and action of clotting factors in humans. However, studies examining the effect of NAFLD due to high-fat high-fructose (HFHF) diet in factor VIII-deficient (haemophilia A) animals or patients have not been reported previously. In this study, we investigated the individual role of factor VIII in the progression of diet-induced NAFLD in the factor 8-/- (F8-/- ) mouse model system and its consequences on the haemophilic status of the mice...

Crosslinked high-performance polymers have many industrial applications but are difficult to recycle. Visual detection of the physical properties of the crosslinked high-performance polymers is useful, but is difficult to achieve. The crosslinked high-performance polymers (SPIN) are constructed by using cation-π interactions. The cation-π interaction between the polymer side chains can be easily installed and removed by aqueous treatments at high or low pH, respectively, which endow the crosslinked polymer with a recyclable behavior...

Quite a number of studies have examined the effects of fish oil supplementation on cognitive performance in different transgenic animal models of Alzheimer's disease (AD). However, inconsistent and controversial outcomes have been derived from these experiments. In order to investigate whether the beneficial effect of fish oil supplementation on cognition was dietary VE status associated, fish oil dietary intervention was carried out in transgenic APPswe /PS1dE9 (APP/PS1) mice. Control mice (C57BL/6J mice) were fed a normal control diet...

BACKGROUND: Studies have shown that astrocytes play an important role in a variety of biological processes, so damage to astrocytes can cause a series of related diseases. Glial cell line-derived neurotrophic factor (GDNF) has always been considered a protective factor for dopamine neurons. However, it remains unclear whether GDNF has a protective effect on glial cells, especially astrocytes. In this study, we put forward the hypothesis that a high concentration of GDNF in the microenvironment of astrocytes exerts an inhibitory effect on the apoptosis of astrocytes by DNA-damaging reagents...
