Pipelines carrying diluted bitumen (dilbit) from Canada's oil sands traverse North America, including the freshwater habitat of Pacific salmon, posing a risk of environmental release and aquatic exposure. Swimming performance is impacted in juvenile sockeye (Oncorhynchus nerka) exposed to dilbit; therefore biomarkers of dilbit exposure will be valuable for monitoring at-risk salmon stocks. This study characterized changes in the serum proteome of sockeye exposed to a sub-lethal and environmentally relevant concentration of dilbit using isobaric tags for relative and absolute quantitation (iTRAQ), and included a range of experimental conditions to permit identification of biomarkers that are robust across time (1 and 4wk) and exercise level (at rest and following a swim test)...

BACKGROUND: Enzymatically modified low density lipoprotein (eLDL), C reactive protein (CRP), dendritic cells (DCs), and T cells were shown to be involved in the pathogenesis of atherosclerosis. This study aimed to investigate whether eLDL and CRP could cooperatively promote DC-mediated T cell activation and proliferation. METHOD: Low density lipoprotein was isolated from healthy human plasma and treated with proteases and cholesterol esterase. CD14(+) monocytes were isolated from human peripheral blood by gradient centrifugation and enriched with CD14 Microbeads, which were then induced with recombinant human IL-4 and granulocyte-macrophage colony-stimulating factor before treated with eLDL and/or CRP...

OBJECTIVE: We introduce a method that quantifies the consistent involvement of intracranially monitored regions in recurrent focal seizures. METHODS: We evaluated the consistency of two ictal spectral activation patterns (mean power change and power change onset time) in intracranial recordings across focal seizures from seven patients with clinically marked seizure onset zone (SOZ). We examined SOZ discrimination using both patterns in different frequency bands and periods of interest...

As early as 2004 the Fingerprint Working Group of the European Network of Forensic Science Institutes (ENFSI) has organised proficiency tests (PT's) as well as collaborative exercises (CE's) as a way of raising standards within the fingerprint profession. Participation in PT's and CE's is a key element in the ISO/IEC accreditation process as they enable laboratories to monitor the quality of their analytical results. On the basis of the European Council Framework Decision 2009/905/JHA, of 30 November 2009, on Accreditation of forensic service providers carrying out laboratory activities[1], from November 15th of 2015, only accredited laboratories are allowed to exchange fingerprint data with other EU countries...

In this paper, we present a quantitative estimation of the impacts of biomass burning emissions from different source regions to the local air quality in Hong Kong in 2014 using global chemistry transport model simulations, sun photometer measurements, satellite observations and local monitoring network data. This study focuses on two major biomass burning pollutants, black carbon aerosols and carbon monoxide (CO). The model simulations of atmospheric black carbon and CO show excellent agreement with sun photometer aerosol optical depth (AOD) measurements, satellite CO columns observations and local monitoring stations data...

Winter survival for many insect species includes a need to maintain metabolic homeostasis and structural/functional integrity of macromolecules not only over a wide range of cold temperatures but also in response to rapid temperature change. Chaperones are well-known to protect/stabilize protein structure with regard to heat stress but less is known about their potential involvement in long-term protection of the proteome at subzero temperatures. The present study assessed the participation of chaperone proteins in the cold hardiness of larvae of the goldenrod gall moth, Epiblema scudderiana (Clemens) (Lepidoptera, Olethreutidae), monitoring changes in nine proteins over the winter months as well as their responses to laboratory cold acclimation or anoxia exposure...

We show that fluorescent avidin binds to basophil cell surface upon degranulation and can be used to set up a new basophil activation test (BAT). This new assay provides results comparable to those provided by the CD63 exposure-based BAT, but has the advantage to directly monitor granule exteriorization.

In Saccharomyces cerevisiae the second messenger cyclic adenosine monophosphate (cAMP) and protein kinase A (PKA) play a central role in metabolism regulation, stress resistance and cell cycle progression. To monitor cAMP levels and PKA activity in vivo in single S. cerevisiae cells, we expressed an Epac-based FRET probe and a FRET-based A-kinase activity reporter, which were proven to be useful live-cell biosensors for cAMP levels and PKA activity in mammalian cells. Regarding detection of cAMP in single yeast cells, we show that in wild type strains the CFP/YFP fluorescence ratio increased immediately after glucose addition to derepressed cells, while no changes were observed when glucose was added to a strain that is not able to produce cAMP...

Proteins and glycoproteins with therapeutic activity are susceptible to environmental factors, which can cause their degradation and the loss of their activity. Thus, the maintenance of their stability during the production process is a critical factor. In this work, a simple and rapid hydrophilic interaction liquid chromatography HILIC-UV method was validated in terms of accuracy, precision, linearity, LOD, LOQ and specificity and applied to the investigation of the stability of intact proteins and their neo-glycoconjugates with antigenic activity against tuberculosis...

Surgical intervention is an inseparable part of the management of serious surgical disease. However, surgery also presents a potential risk related to the so-called surgical injury causing immune response. When dysregulated the immune activation is able to cause local complications (i.e. wound dehiscence, impaired healing). Systemic decompartmentization of the immunologic disturbance can negatively influence long-term outcomes (i.e. hospital length of stay, mortality). Due to aseptic conditions in the operating room, such an immune activation is almost always of sterile nature...

Red mud can be applied as soil ameliorant to acidic, sandy and micronutrient deficient soils. There are still knowledge gaps regarding the effects of red mud on the soil microbial community. The Biolog EcoPlate technique is a promising tool for community level physiological profiling. This study presents a detailed evaluation of Biolog EcoPlate data from two case studies. In experiment "A" red mud from Ajka (Hungary) was mixed into acidic sandy soil in soil microcosms at 5-50 w/w%. In experiement "B" red mud soil mixture was mixed into low quality subsoil in a field experiment at 5-50 w/w%...

A dislodgeable foliar residue study was conducted in greenhouse pepper and tomato on the island of Crete, Greece, following the spray application of an SC insecticide (with active substance (a.s.) tebufenozide) and an EC fungicide (a.s. bupirimate). Furthermore, for the assessment of worker exposure to pesticides - as a result of re-entering the treated crops - a worker dermal exposure study was carried out during the tasks of tying or pruning, which allowed the transfer coefficient values for the specific tasks to be determined...

Laura Carrera-García, Maximiliano Francisco Rivas-Crespo, María Soledad Fernández García
Androgenic actions require the proper signal transmission by the androgen receptor (AR), a nuclear transcription factor. This is initially located in the cell cytoplasm and should translocates to the nucleus to interact with DNA. AR functional impairment causes diverse blockage degrees of androgenic steroid action, known as androgen insensitivity syndromes. Filamin A, a protein coded by the FLNA gene, is a co-activator of various cytoplasmic factors, including AR. The mutational inactivation of the FLNA gene induces insufficiency of translocation and activation of AR...

BACKGROUND: Analgesia might be evaluated with simple changes in vital signs, a non-specific and non-sensitive method. Heart rate variability (HRV) correlates with autonomous nervous system activity and can be used to evaluate painful stimuli. Heart rate variability is then transformed into a numeric scale called the analgesia nociception index (ANI), where higher values represent predominant parasympathetic tone, thus low nociception. Under general anesthesia, the ANI decreases following painful stimuli and increases after administration of analgesia, but significant interindividual variability is present...

Contextual information allows the human brain to make predictions about the identity of objects that might be seen and irregularities between an object and its background slow down perception and identification processes. Bar and colleagues modeled the mechanisms underlying this beneficial effect suggesting that the brain stocks information about the statistical regularities of object and scene co-occurrence. Their model suggests that these recurring regularities could be conceptualized along a continuum in which the probability of seeing an object within a given scene can be high (probable condition), moderate (improbable condition) or null (impossible condition)...

OBJECTIVE: Active surveillance is an option for patients with papillary thyroid microcarcinoma (PTMC). However, the long-term clinical outcomes after delayed surgery remain unclear. We compared the long-term clinical outcomes of PTMC patients according to the time interval between initial diagnosis and surgery. DESIGN & METHODS: In this individual risk factor-matched cohort study, PTMC patients were classified into three groups according to the delay period: ≤ 6 months, 6-12 months, and > 12 months...

Mineralocorticoid and glucocorticoid receptors are closely related steroid hormone receptors that regulate gene expression through many of the same hormone response elements. However, their transcriptional activities and effects in skeletal muscles are largely unknown. We recently identified mineralocorticoid receptors (MR) in skeletal muscles after finding that combined treatment with the angiotensin-converting enzyme inhibitor lisinopril and MR antagonist spironolactone was therapeutic in Duchenne muscular dystrophy mouse models...

BACKGROUND: Patients suffering from depression have a high risk of relapse and readmission in the weeks following discharge from inpatient wards. Electronic self-monitoring systems that offer patient-communication features are now available to offer daily support to patients, but the usability, acceptability, and adherence to these systems has only been sparsely investigated. OBJECTIVE: We aim to test the usability, acceptability, adherence, and clinical outcome of a newly developed computer-based electronic self-assessment system (the Daybuilder system) in patients suffering from depression, in the period from discharge until commencing outpatient treatment in the Intensive Outpatient Unit for Affective Disorders...
