Electrochemically Assisted Biosensors

This chapter describes a study focusing on electrochemically assisted biosensors. Electrochemical regeneration of electron-transfer mediators or cofactors, such as NAD+ has been extensively applied in redox reactions catalyzed by oxidoreductases. This electrochemical regeneration shows many advantages in use of amperometric biosensors, such as extended linear range. To demonstrate the feasibility

Assays for Evaluation of Substrates for and Inhibitors of β-1,4-Galactosyltransferase 7

β-1,4-Galactosyltransferase 7 (β4GalT7) is a key enzyme in the synthesis of two classes of glycosaminoglycans (GAG), i.e., heparan sulfate (HS) and chondroitin/dermatan sulfate (CS/DS). GAG chains are linear polysaccharides of alternating hexuronic acid and N-acetylhexosamine residues, commonly linked to core proteins to form proteoglycans with important roles in the regulation of a range of biolo

An Anterior Cruciate Ligament Rupture Increases Levels of Urine N-terminal Cross-linked Telopeptide of Type I Collagen, Urine C-terminal Cross-linked Telopeptide of Type II Collagen, Serum Aggrecan ARGS Neoepitope, and Serum Tumor Necrosis Factor–α

Background: An anterior cruciate ligament (ACL) rupture results in an increased risk of developing knee osteoarthritis (OA) at an early age. Before clinical signs become apparent, the OA process has already been initiated. Therefore, it is important to look at the cascade of changes, such as the activity of cytokines and proteases, which might be associated with the later development of OA. Purpos

Production and HPLC-Based Disaccharide Analysis of Xyloside-Primed Glycosaminoglycans

Although glycosaminoglycans (GAGs) are known to be involved in a variety of physiological and pathological processes, knowledge about their expression by cells or tissues, the GAGome, is limited. Xylosides can be used to induce the formation of GAGs without the presence of a proteoglycan core protein. The administration of xylosides to living cells tends to result in a considerable amplification i

Proposed cutoff for fetal scalp blood lactate in intrapartum fetal surveillance based on neonatal outcomes : a large prospective observational study

OBJECTIVE: Determination of lactate in fetal scalp blood (FBS) during labour has been recognised since the 1970s. The internationally accepted cutoff of >4.8 mmol/l indicating fetal acidosis is exclusive for the point-of-care device (POC) LactatePro™, which is no longer in production. The aim of this study was to establish a new cutoff for scalp lactate based on neonatal outcomes with the use of t

Development of a parent-reported screening tool for avoidant/restrictive food intake disorder (ARFID) : Initial validation and prevalence in 4-7-year-old Japanese children

The prevalence of avoidant/restrictive food intake disorder (ARFID) in the general child population is still largely unknown and validated screening instruments are lacking. The aims of this study were (1) to investigate the prevalence of children screening positive for ARFID in a Japanese birth cohort using a newly developed parent-reported screening tool, (2) to estimate the prevalence of childr

Search for dark matter produced in association with a single top quark in √s=13 TeV pp collisions with the ATLAS detector

This paper presents a search for dark matter in the context of a two-Higgs-doublet model together with an additional pseudoscalar mediator, a, which decays into the dark-matter particles. Processes where the pseudoscalar mediator is produced in association with a single top quark in the 2HDM+a model are explored for the first time at the LHC. Several final states which include either one or two ch

Brain pathology in focal status epilepticus : evidence from experimental models

Status Epilepticus (SE) is often a neurological emergency characterized by abnormally sustained, longer than habitual seizures. The new ILAE classification reports that SE “…can have long-term consequences including neuronal death, neuronal injury…depending on the type and duration of seizures”. While it is accepted that generalized convulsive SE exerts detrimental effects on the brain, it is not

Curcuma as an adjuvant in colorectal cancer treatment

Colorectal cancer (CRC) is the second leading cause of cancer death worldwide and mostly affects men. Around 20% of its incidence is by familiar disposition due to hereditary syndromes. The CRC treatment involves surgery and chemotherapy; however, the side effects of treatments and the fast emergence of drug resistance evidence the necessity to find more effective drugs. Curcumin is the main polyp

Risk of Major Bleeding in Patients With Atrial Fibrillation Taking Dronedarone in Combination With a Direct Acting Oral Anticoagulant (From a U.S. Claims Database)

Dronedarone may increase exposure and the risk of major bleeding when prescribed with a direct oral anticoagulant (DOAC). This retrospective cohort study examined the risk of the first occurrence of major bleeding (hospitalization or emergency room visit for gastrointestinal [GI] bleeding, intracranial hemorrhage [ICH], or bleeding at other sites) among new users of apixaban, dabigatran, and rivar

Experimental study and modeling of the heat flux acting on the tool flank when machining

Adequate setting of the boundary conditions for the heat equation when modeling the temperature distribution in the cutting tool is one of the key points. The boundary conditions on the tool surfaces can be divided into two groups: conditions that describe heat losses (heat exchange with the environment) and conditions that characterize the heat source that heats up the tool (heat flux from the cu

Hip and groin function and strength in male ice hockey players with and without hip and groin problems in the previous season- a prospective cohort study

Objective: To describe and compare hip and groin strength and function of male ice hockey players over one season in players with and without hip and groin problems in the previous season. Design: Prospective cohort study. Setting: Swedish male ice hockey. Participants: We followed 193 players from 10 teams during the 2017/2018 season. Main outcome measures: Hip adduction and abduction strength, 5

Neonatal hypoxic-ischaemic encephalopathy : Motor impairment beyond cerebral palsy

Background: Research investigating neuromotor function in the absence of cerebral palsy (CP) for children who had neonatal HIE is limited. Aims: To investigate school-age neurological and neuromotor function, and correlations with attention, neonatal Magnetic Resonance Imaging (MRI), and neuromotor assessments at toddler age. Methods: Twenty-seven children with neonatal HIE without CP who underwen

CHEOPS precision phase curve of the Super-Earth 55 Cancri e

Context. 55 Cnc e is a transiting super-Earth (radius 1.88 R⊕ and mass 8 M⊕) orbiting a G8V host star on a 17-h orbit. Spitzer observations of the planet's phase curve at 4.5 μm revealed a time-varying occultation depth, and MOST optical observations are consistent with a time-varying phase curve amplitude and phase offset of maximum light. Both broadband and high-resolution spectroscopic analyses

HUGO Gene Nomenclature Committee (HGNC) recommendations for the designation of gene fusions

Gene fusions have been discussed in the scientific literature since they were first detected in cancer cells in the early 1980s. There is currently no standardized way to denote the genes involved in fusions, but in the majority of publications the gene symbols in question are listed either separated by a hyphen (-) or by a forward slash (/). Both types of designation suffer from important shortco

Work experiences, resources, and beliefs among vulnerable subgroups of mental health care users

BACKGROUND: People with mental illness may have difficulties related to work and employment, especially if they experience additional difficult life situations. OBJECTIVE: To explore how subgroups with mental illness and additional adversities perceived their situation with respect to work and employment prospects. METHODS: Three subgroups were included, exposed to an additional difficult life sit
