Naphthalene Decomposition on Fe(110)─Adsorption, Dehydrogenation, Surface Carbon Formation and the Influence of Coadsorbed Oxygen

Tar is an undesirable byproduct of biomass gasification, which can be removed through catalytic reforming to syngas components. Iron is a promising, abundant alternative to highly active but toxic nickel catalysts. The results observed so far in catalytic studies with iron have been mixed. In this paper, the decomposition of naphthalene, a representative model compound of tar, was studied on the c

Integrative analyses of circulating microRNA expression profile in hexavalent chromium exposed workers - A cross-sectional study within the SafeChrom project

Background Exposure to hexavalent chromium (Cr(VI)) can occur during occupational activities and leading lung cancer. MicroRNA (miRNA) plays an important part in carcinogenesis. Whether Cr(VI) exposure causes cancer-related miRNA changes is yet uncharacterized. Methods This study included 89 Cr(VI) exposed workers and 47 controls. MiRNAs were extracted from plasma followed by library preparations,

Assessing toxicity of PM2.5 from indoor sources and during exposure in private homes

Toxicological testing in mice was conducted on PM2.5 particles from stressed burning of two types of candles (white and blue) and on PM2.5 collected indoor and outdoor of fifteen occupied homes in southern Sweden. As an indicator of toxicity, the ability to generate Reactive Oxygen Species (ROS) was also assessed for all pooled samples: candle white, candle blue, indoor, and outdoor. Higher toxici

A comparison of approaches integrating power take-off systems into wave energy converters simulations

In the design of a wave energy converter (WEC) in general, one critical aspect is to develop thepower take-off (PTO) system since it has a significant impact on the overall energy harnessing efficiency. There-fore, the modelling of a PTO system should be considered in the simulation of a WEC and carefully tuned with itsparameters to guarantee prediction accuracy. However, it is a challenge to mode

A Swedish dietary guideline index, gut microbial α-diversity and prevalence of metabolic syndrome – observations in the Swedish CArdioPulmonary bioImage Study (SCAPIS)

Background: Metabolic syndrome (MetS) is characterized by coexisting risk factors for type 2 diabetes and cardiovascular disease. Diet is of importance in their aetiology, and gut microbiota (GM) may constitute a link between diet and metabolic health. Understanding the interplay between diet and GM could contribute novel insights for future dietary guidelines, and aid in preventive actions to mot

Recording of non-musculoskeletal manifestations, comorbidities and safety outcomes in European spondyloarthritis registries : A survey

Objectives: Real-world evidence is needed to inform treatment strategies for patients with PsA and axial SpA (axSpA) who have non-musculoskeletal manifestations (NMMs), various risk factors and comorbidities. International collaboration is required to ensure statistical power and to enhance generalizability. The first step forward is identifying which data are currently being collected. Across 17

Rimegepant for the acute and preventive treatment of migraine : a narrative review of the evidence

Introduction: Rimegepant is an oral small-molecule calcitonin gene-related peptide receptor antagonist approved in several countries for acute treatment of migraine and preventive treatment of episodic migraine in adults. This review summarizes the evidence, published to date, for the use of rimegepant as an acute or preventive treatment of migraine. Areas covered: A brief overview of migraine, th

Drug Treatment

A short review is given of current literature on medical alternatives for managing neurogenic bladder (NGB) by treating detrusor overactivity (NDO) and improving bladder compliance and urinary incontinence. The first goal of treatment of NGB is to protect the upper tract from damage, and the second is to maintain urinary continence, but all the while maintaining the patient’s quality of life. The

Thirteenth-Century Aristotelian Logic : The Study of Scientific Method

The aims of this paper are to show (i) that thirteenth-century Aristotelian logic (AL-13) is a logical tradition that considers Aristotelian logic (AL: the logical curriculum at the University of Paris, that is, Porphyry’s Isagoge, Aristotle’s Organon, Boethius’s De divisione and De topicis differentiis, and the anonymous Sex principia) as a system that is organized around the syllogistic argument

Self-reported physical activity more than 1 year after stroke and its determinants in relation to the WHO recommendations

BACKGROUND: Physical activity (PA) after stroke has significant health benefits if it is conducted regularly, with sufficient intensity and duration. Because of the health benefits, it is important to identify those below the World Health Organization (WHO) recommended level of PA. However, few studies have assessed the level of PA after stroke in relation to the WHO recommendations and which soci

Event-related theta synchronization over sensorimotor areas differs between younger and older adults and is related to bimanual motor control

When engaged in dynamic or continuous movements, action initiation involves modifying an ongoing motor program rather than initiating it from rest. Event-related theta synchronization over sensorimotor areas is a neurophysiological marker for modifying motor programs. We used electroencephalography (EEG) to examine how task complexity and age affect event-related synchronization (ERS) in the theta

How new generation techniques are shaping the future of environmental sciences

This perspective highlights the role of new-generation analytical techniques in future applications in environmental sciences since the shift to the One Health research paradigm. It reviews the interactions between the compartments of One Health and indicates the current challenges in traditional environmental research. The term One Health was first used at the beginning of the 20th century, yet m

Intraoperative Nerve Monitoring in Thyroid Operations

Injury to the recurrent laryngeal nerve (RLN) is a rare but dreaded complication of thyroid surgery. Intraoperative nerve monitoring (IONM) is a technology intended to assist surgeons in identifying the RLN and confirming its function. This chapter describes the technology and technique of IONM, with tips for utilization and interpretation of results. A review of the existing literature on the res

Stress-Related Disorders among Young Individuals with Surgical Removal of Tonsils or Adenoids

Importance: Studies have suggested an increased risk of psychiatric disorders and suicidal behavior among individuals who have undergone tonsillectomy. However, little is known about stress-related disorders. Objective: To investigate whether surgical removal of tonsils or adenoids is associated with a subsequent risk of stress-related disorders. Design, Setting, and Participants: This cohort stud

Mycorrhiza-dependent drivers of the positive rhizosphere effects on the temperature sensitivity of soil microbial respiration in subtropical forests

Tree roots and their fungal symbionts mediate the response of rhizosphere soil organic carbon (SOC) decomposition to climate warming, specifically the temperature sensitivity of soil microbial respiration (Q10), which is a critical parameter for projecting the magnitude of terrestrial soil C-climate feedbacks. However, the intensity of the rhizosphere effects (RE; rhizosphere soils vs. bulk soils)
