Abstract
The REIMEP-22 inter-laboratory comparison aimed at determining the production date of a uranium certified test sample (i.e. the last
chemical separation date of the material). Participants in REIMEP-22 on “U Age Dating – Determination of the production
date of a uranium certified test sample” received one low-enriched 20 mg uranium sample for mass spectrometry measurements
and/or one 50 mg uranium sample for α-spectrometry measurements, with an undisclosed value for the production
date. They were asked to report the isotope amount ratios n(230Th)/n(234U) for the 20 mg uranium sample and/or the
activity ratios A(230Th)/A(234U) for the 50 mg uranium sample in addition to the calculated production date of the
certified test samples with its uncertainty. Reporting of the 231Pa/235U ratio and the respective calculated
production date was optional.
Eleven laboratories reported results in REIMEP-22. Two of them reported results for both the 20 mg and 50 mg
uranium certified test samples. The measurement capability of the participants was assessed against the independent REIMEP-22 reference
value by means of z- and zeta-scores in compliance with ISO 13528:2005. Furthermore a performance assessment criterion for acceptable
uncertainty was applied to evaluate the participants' results. In general, the REIMEP-22 participants' results were satisfactory. This
confirms the analytical capabilities of laboratories to determine accurately the age of uranium materials with low amount of ingrown
thorium (young certified test sample). The Joint Research Centre of the European Commission (EC-JRC) organised REIMEP-22 in parallel to
the preparation and certification of a uranium reference material certified for the production date (IRMM-1000a and IRMM-1000b).

Published: September 2015

Summary
Chelating agents are used to remove various inorganic scales, including sulfates and carbonates. They are also used as standalone stimulation fluids and as iron-control agents during acidizing treatments. The main chelating agents used in the oil field include ethylenediaminetetraacetic acid (EDTA), nitrilotriacetic acid (NTA), N-(hydroxyethyl)-ethylenediaminetriacetic acid (HEDTA), and glutamic acid diacetic acid (GLDA). (Note that the abbreviations for these chelating agents will be used throughout the rest of the paper.) One of the concerns with these chelants is their thermal stability at elevated temperatures.
Chelant solutions (0.7 to 0.8 M) of HEDTA, GLDA, NTA, EDTA, and their mono-/disalts were prepared. The aqueous solutions of these chelants were heated at various temperatures (300 to 400°F) and times (2 to 12 hours). The concentration of chelant was measured with a titration method that uses FeCl3 solutions. The products of thermal decomposition of chelants were determined with mass spectrometry (MS) and gas-chromatography/MS techniques.
Most chelants decomposed at temperatures greater than 350°F. At 400°F and after 12 hours of heating, diammonium salt of GLDA degraded more quickly than diammonium salt of EDTA chelant. Analyses of NH4H3GLDA with MS techniques after heating highlighted that the decomposition products included iminodiacetic acid, hydroxyacetic acid, and α-hydroxyglutaric acid. Studying the kinetics of aqueous solutions of NaH3GLDA, NaH2HEDTA, and (NH4)2H2EDTA showed that their thermal-degradation kinetics followed a pseudofirst-order reaction. The Arrhenius equation can be used to predict the activation energy that is necessary for the degradation mechanisms of chelants.

Published: September 2015

OBJECT
In elderly patients with severe osteoporosis, instrumented lumbar interbody fusion may result in fixation failure or nonunion because of decreased pedicle screw pullout strength or increased interbody graft subsidence risk. Thus, given its many advantages, percutaneous pedicle screw fixation with cement augmentation can be an effective method to use in elderly patients. The authors report on an easy, safe, and economical technique for bone cement augmentation using a bone biopsy needle inserted into the disc space in 2 osteoporotic patients who were treated with posterior interbody fusion and percutaneous pedicle screw fixation.

METHODS
Two elderly patients who complained of back pain and intermittent neurological claudication underwent posterior interbody fusion with percutaneous pedicle screw fixation. After routinely assembling rods on the screws, a bone biopsy needle was inserted into the disc space via the operative field; the needle was then placed around the tips of the screws using fluoroscopic radiography for guidance. Bone cement was injected through the bone biopsy needle, also under fluoroscopic radiography guidance.

RESULTS
Both patients’ symptoms improved after the operation, and there was no evidence of cage subsidence or screw loosening at the 4-month follow-up.

CONCLUSIONS
The indirect technique of bone cement augmentation via the disc space for percutaneous screw fixation could be an easy, safe, and economical method.

Published: September 2015

Notre travail s’intéresse aux personnes vivant en situation de grande précarité dans les rues de Lille. L’article montre les liens entre leurs consommations de substances psychoactives (SPA) et leurs activités rémunératrices. L’achat de doses d’héroïne constitue une dépense considérable pour des individus qui multiplient les carences sociales (logement, emploi, santé, famille, etc.). C’est en recourant à la mendicité et à diverses combines qu’ils parviennent à financer leur vie quotidienne et leurs consommations de drogues. La vente ou la revente de drogues et de médicaments psychotropes constitue aussi une solution. En contribuant à éclairer les relations d’influences multiples entre usages de drogues et recherche d’argent, cette étude montre que les activités de ces personnes aux « marges du travail » s’insèrent dans une économie globale et que ces diverses activités contribuent à assurer leurs propres consommations de drogues et, plus indirectement, celles d’usagers insérés.

Abstract
Introduction: Incidence of anomalous coronary arteries is rare and has been recognized as the causative factor for myocardial ischemia and sudden death. Knowledge about the variations of coronary arterial origin and its course provide a valuable guide to Cardiothoracic Surgeons and Physicians and be useful for producing devices appropriate for variant anatomical structures. The aim of the study was to investigate the number and position of the coronary ostia, emphasizing their possible clinical implications. Methods: Fifty one formalin fixed adult heart specimens were dissected to conduct a morphometric study on coronary ostia and establish their relation with respective aortic sinuses. In addition, branching pattern of the right coronary artery and its dominance were documented. Results: Variations in number and position of ostia in both sinuses were noted. Of the 96 ostia analyzed in the present study, 64.5% were located below the intercommissural line, 11.4% above it and 18.7% at its level. Mean diameter of right and left ostia was measured as 3.03mm and 2.9mm respectively. Mean distance of right and left ostia from their respective sinuses was found to be 15.14mm and 14.20mm respectively. Conclusion: Knowledge of normal and variant anatomy of coronary circulation is a vital component in diagnoses of congenital and acquired cardiac diseases. This study will provide additional information about variations of coronary artery to clinicians and manufacturers to plan their approach for safer and successful treatment.

Abstract
Introduction: Mushroom extracts are used, mainly due to immunomodulatory and antitumor proprierties. Among the general and species is the Agaricus brasiliensis or SunMushroom. However herbal remedies can cause changes in morphology and functionality of various organs. Therefore, these reporters need to be analyzed for applicability of this compound. The aim of the present study was to analyze the structural characteristics of the heart of Swiss mice employing light microscopy and scanning electron microscopy methods. Materials and methods: Swiss mice were used, divided into 2 groups: Control (n=6) and Agaricus brasiliensis (n=6), and the second group treated with the extract daily. After 60 days, under anesthesia withdrew from the samples, which were submitted to histological routine for obtaining serial sections. Results: Microscopic analysis revealed the aspects of the heart of Swiss mice: The formation of layers (epicardium, myocardium and endocardium) with partial view of the papillary muscles. Using the technique of Picro-Sirius: In yellow, the muscle fibers; in red, collagen fibers. Under polarized light, show the types of collagen fibers in red and green, significant collagen type I and III respectively. Conclusion: The arrangement of muscle fibers and collagen did not vary between the two groups.

Authors: Uszynski Marcin , Purtill Helen , Coote Susan 
Published: September 2015

Background: Sensory disturbances are a major problem for people with multiple sclerosis (MS), and up to 80% of people with MS present with various sensory deficits. To date, only one study has investigated the reliability of sensory measures in people with MS. We sought to determine the interrater reliability of the verbal analogue scale (VAS), the Erasmus MC modifications to the revised Nottingham Sensory Assessment (EmNSA), Semmes-Weinstein monofilaments (SWMs), and the neurothesiometer (NT) in people with MS.
Methods: A random sample of 34 people with MS who could walk independently with or without a device was tested by two raters on the same day. For categorical data, percentage agreement, Cohen's kappa, and prevalence-adjusted bias-adjusted kappa were used. For continuous data, interclass correlation coefficient (ICC[2,1]) with 95% confidence intervals (95% CIs), Bland and Altman analysis, and standard error of measurement (SEM) were calculated.
Results: For NT, ICC(2,1) values were good, with the highest for first metatarsophalangeal joint (ICC[2,1] = 0.84, 95% CI = 0.69–0.92, SEM = 4.98). The highest ICC(2,1) for VAS was for the question relating to feeling numbness in the hand (ICC[2,1] = 0.93, 95% CI = 0.86–0.96, SEM = 0.64). Findings for EmNSA and SWMs need further verification owing to possible ceiling effects.
Conclusions: The NT and VAS had good interrater reliability and should be considered for measuring sensation in ambulatory people with MS. Findings for EmNSA and SWMs revealed either questionable or poor reliability, suggesting the need for further investigation.

ImportancePolycystic ovary syndrome (PCOS) is a common endocrine disorder, characterized by subfertility, increased risk of metabolic diseases, and pregnancy complications. Previous studies diverge regarding the association between maternal PCOS and newborn anthropometrics.ObjectiveTo explore the association between maternal PCOS and newborn anthropometrics and the modifying effects of maternal body mass index, PCOS phenotype, and gestational diabetes.Design, Setting, and ParticipantsThis cohort study followed up women from the first half of pregnancy to birth and combined data from 3 clinical trials of pregnant women with PCOS and a reference population consisting of participants in the Norwegian Mother, Father, and Child Cohort (MoBa) Study, with data from the Medical Birth Registry of Norway. The recruitment period for the clinical trials was between October 1, 2000, and August 31, 2017, and for MoBa, between July 1, 1999, and December 31, 2008. Participants included women with singleton pregnancies and live-born children. Data were analyzed from January 1 to June 15, 2023.ExposureMaternal PCOS status.Main Outcomes and MeasuresNewborn birth weight, birth length, and head circumference as continuous variables and z scores, and ponderal index (calculated as the birth weight in grams × 100 divided by the birth length in centimeters cubed), placenta weight, and ratio of birth weight to placenta weight (BWPW).ResultsThe cohort included 390 pregnant women with PCOS (mean [SD] age, 29.6 [4.2] years) and 68 708 women in the reference group (mean [SD] age, 30.4 [4.5] years). Offspring in the PCOS group had lower birth weight, birth length, and head circumference than in the reference group offspring. The estimated mean differences in z scores were −0.26 (95% CI, −0.38 to −0.14) for birth weight, −0.19 (95% CI, −0.33 to −0.05) for birth length, and −0.13 (95% CI, −0.26 to −0.01) for head circumference. The PCOS group also had a lower ponderal index (−0.04 [95% CI, −0.07 to −0.004] g × 100/cm3) and placenta weight (−24 [95% CI, −43 to −5)] g), and higher BWPW ratio (0.4 [95% CI, 0.3 to 0.5]). The association between growth restriction and PCOS was more apparent when additionally adjusting for body mass index. Neither PCOS phenotype nor gestational diabetes diagnosis was associated with neonatal anthropometry in women with PCOS.Conclusions and RelevanceIn this cohort of mother-infant pairs, maternal PCOS status was associated with lower birth weight, shorter birth length, and smaller head circumference in the offspring. This growth restriction was more pronounced when adjusting for BMI, providing insight into the association between PCOS and body mass index. The study contributed to the understanding of how PCOS affects the offspring.

AbstractBackgroundBolus materials have been used for decades in radiotherapy. Most frequently, these materials are utilized to bring dose closer to the skin surface to cover superficial targets optimally. While cavity filling, such as nasal cavities, is desirable, traditional commercial bolus is lacking, requiring other solutions. Recently, investigators have worked on utilizing 3D printing technology, including commercially available solutions, which can overcome some challenges with traditional bolus.PurposeTo utilize failure modes and effects analysis (FMEA) to successfully implement a comprehensive 3D printed bolus solution to replace commercial bolus in our clinic using a series of open‐source (or free) software products.Methods3D printed molds for bespoke bolus were created by exporting the DICOM structures of the bolus designed in the treatment planning system and manipulated to create a multipart mold for 3D printing. A silicone (Ecoflex 00–30) mixture is poured into the mold and cured to form the bolus. Molds for sheet bolus of five thicknesses were also created. A comprehensive FMEA was performed to guide workflow adjustments and QA steps.ResultsThe process map identified 39 and 30 distinct steps for the bespoke and flat sheet bolus workflows, respectively. The corresponding FMEA highlighted 119 and 86 failure modes, with 69 shared between the processes. Misunderstanding of plan intent was a potential cause for most of the highest‐scoring failure modes, indicating that physics and dosimetry involvement early in the process is paramount.ConclusionFMEA informed the design and implementation of QA steps to guarantee a safe and high‐quality comprehensive implementation of silicone bolus from 3D printed molds. This approach allows for greater adaptability not afforded by traditional bolus, as well as potential dissemination to other clinics due to the open‐source nature of the workflow.

AbstractObjectiveThe piriform cortex is considered to be highly epileptogenic. Its resection during epilepsy surgery is a predictor for postoperative seizure freedom in temporal lobe epilepsy. Epilepsy is associated with a dysfunction of the blood–brain barrier. We investigated blood–brain barrier dysfunction in the piriform cortex of people with temporal lobe epilepsy using quantitative T1‐relaxometry.MethodsGadolinium‐based contrast agent was administered ictally and interictally in 37 individuals before undergoing quantitative T1‐relaxometry. Postictal and interictal images were co‐registered, and subtraction maps were created as biomarkers for peri‐ictal (∆qT1interictal‐postictal) and interictal (∆qT1noncontrast‐interictal) blood–brain barrier dysfunction. Values were extracted for the piriform cortex, hippocampus, amygdala, and the whole cortex.ResultsIn temporal lobe epilepsy (n = 14), ∆qT1noncontrast‐interictal was significantly higher in the piriform cortex than in the whole cortex (p = 0.02). In extratemporal lobe epilepsy (n = 23), ∆qT1noncontrast‐interictal was higher in the hippocampus than in the whole cortex (p = 0.05). Across all individuals (n = 37), duration of epilepsy was correlated with ∆qT1noncontrast‐interictal (ß = 0.001, p < 0.001) in all regions, while the association was strongest in the piriform cortex. Impaired verbal memory was associated with ∆qT1noncontrast‐interictal only in the piriform cortex (p = 0.04). ∆qT1interictal‐postictal did not show differences in any region.InterpretationInterictal blood–brain barrier dysfunction occurs in the piriform cortex in temporal lobe epilepsy. This dysfunction is linked to longer disease duration and worse cognitive deficits, emphasizing the central role of the piriform cortex in the epileptogenic network of temporal lobe epilepsy.

Face‐centered cubic (fcc) metals deposited onto crystalline substrates grow heteroepitaxially with specific orientation relationships (ORs). The ORs depend on a number of factors including lattice mismatch, bonding and the relative symmetry between the surface and the film. Less explored factors include defects like growth and annealing twins. In this study, a high density of nanotwins in as‐deposited films delay grain growth of OR1 (, ) grains up to 0.56 Tm. A new OR with respect to the c‐sapphire substrate is found, compared to the well‐known OR1 and OR2 which grow with the . This is named OR3, grows above 0.56 Tm with . The OR3 growth is related to strain and defect energy advantage. An unusual OR accompanies OR3 in most films, occupying an area fraction of >0.3. A minute (<0.05) but consistent fractions of , , , and all parallel to and related to annealing twins in exact and near and grains are observed. The study opens new directions in the crystallography of ORs, considering the role of twins in addition to the surface and strain energies.

Published: August 2024

AbstractThe donor–acceptor (D–A) dye 4‐(bis‐4‐(5‐(2,2‐dicyano‐vinyl)‐thiophene‐2‐yl)‐phenyl‐amino)‐benzoic acid (P1) has been frequently used to functionalize NiO photocathodes and induce photoelectrochemical reduction of protons when coupled to a suitable catalyst. Photoinduced twisting of the P1 dye is steered on NiO by co‐adsorption of tetradecanoic acid (C14, myristic acid (MA)). Density Functional Theory and time‐resolved photoluminescence studies confirm that twisting lowers the energy levels of the photoexcited D–A dye. The apolar environment provided by the MA suppresses photoinduced D–A twisting, retards charge recombination following photoinduced charge separation between P1 and NiO, and provides a larger electrochemical potential increasing the photocurrent. Very interestingly, co‐adsorption of MA induces H2 evolution upon photoexcitation without the presence of an H2 evolution catalyst. Based on prior art, the formation of H2 is assigned to the dissolution of Ni2+, followed by reduction and re‐deposition of Ni nanoparticles acting as the catalytically active site. It propose that only excited P1 with suppressed twisting provides the sufficient electrochemical potential to induce deposition of Ni nanoparticles. The work illustrates the importance of understanding the effects of photoinduced intramolecular twisting and highlights the promise of designing twisting‐limited D–A dyes to create efficient solar fuel devices.
