description: The ability to mentalize (i.e., to form representations of mental states and processes of oneself and others) is often impaired in people with schizophrenia spectrum disorders. Emotional awareness (EA) represents one aspect of affective mentalizing and can be assessed with the Levels of Emotional Awareness Scale (LEAS), but findings regarding individuals with schizophrenia spectrum disorders are inconsistent. The present study aimed at examining the usability and convergent validity of the LEAS in a sample of N = 130 stabilized outpatients with schizophrenia or schizoaffective disorders. An adequacy rating was added to the conventional LEAS rating to account for distortions of content due to, for example, delusional thinking. Scores of the patient group were compared with those of a matched healthy control sample. Correlation with symptom clusters, a self-report measure of EA, a measure of synthetic metacognition (MAS-A-G), and an expert rating capturing EA from the psychodynamic perspective of psychic structure (OPD-LSIA) were examined. Regarding self-related emotional awareness, patients did not score lower than controls neither in terms of conventional LEAS nor in terms of adequacy. Regarding other-related emotional awareness, however, patients showed a reduced level of adequacy compared to controls whereas no such difference was found for conventional LEAS scores. Higher conventional LEAS scores were associated with fewer negative symptoms, and higher structural integration of self-perceptions measured by the OPD-LSIA. Higher adequacy of responses correlated with fewer symptoms of disorganization as well as excitement, higher scores of self-reflection on the MAS-A-G as well as self- and object-perception and internal and external communication as measured by the subscales of the OPD-LSIA. Findings suggest that the LEAS might not be sensitive enough to detect differences between mildly symptomatic patients with schizophrenia or schizoaffective disorders and healthy controls. However, LEAS ratings are still suitable to track intraindividual changes in EA over time. Observing the adequacy of patients' responses when using the LEAS may be a promising way to increase diagnostical utility and to identify patterns of formal and content-related alterations of mentalizing in this patient group. Methodological indications for future studies are discussed.

description: An optical sensor for hydrogen peroxide (HP) based on the probe europium tetracycline (EuTc) incorporated into a polyacrylonitrile-co-polyacrylamide polymer matrix is described. Upon optical excitation with 400-nm light, the EuTc in the membrane displays fairly strong fluorescence peaking at 616nm. The fluorescence intensity increases up to 3-fold if the sensor is exposed to solutions containing HP. The effect is reversible and can thus be used for continuous sensing. The largest signal changes with HP are observed at pH levels between 6.5 and 7.5, and the range of the response is between 10 and 300ppm (w/w) of HP, equal to 0.3 to 10mmolL–1). At concentrations above 0.3% of HP, decomposition of the EuTc in the membrane is observed. The limit of detection is 15ppm (0.45mmolL–1). The response is fully reversible and rather slow (10min) in both directions, but the reverse response may be accelerated by addition of a reducing agent such as thiosulfate. Alkali ions and most anions remain inert, but phosphate and citrate interfere, as do Cu2+ ions, which quench fluorescence. In order to image the spatial distribution of HP concentrations, sensor membranes were placed on the bottom of the wells of a microtiter plate, and their fluorescence was imaged using an LED-based device based on the measurement of the luminescence decay time of EuTc. If glucose oxidase is immobilized on the sensor layer, a glucose sensor is obtained in which the HP sensor acts as the transducer and which can quantify glucose in concentrations between 0.1 and 5mmolL–1. The limit of detection for glucose is 0.2mmolL–1.

description: Sun-like stars are promising candidates to host exoplanets and are often included in exoplanet surveys by radial velocity (RV) and direct imaging. In this paper we report on the detection of a stellar companion to the nearby solar-analogue star HD 104304, which previously was considered to host a planetary mass or brown dwarf companion. We searched for close stellar and substellar companions around extrasolar planet host stars with high angular resolution imaging to characterize planet formation environments. The detection of the stellar companion was achieved by high angular resolution measurements, using the "Lucky Imaging" technique at the ESO NTT 3.5m with the AstraLux Sur instrument. We combined the results with VLT/NACO archive data, where the companion could also be detected. The results were compared to precise RV measurements of HD 104304, obtained at the Lick and Keck observatories from 2001-2010. We confirmed common proper motion of the binary system. A spectral type of M4V of the companion and a mass of 0.21 M_Sun was derived. Due to comparison of the data with RV measurements of the unconfirmed planet candidate listed in the Extrasolar Planets Encyclopaedia, we suggest that the discovered companion is the origin of the RV trend and that the inclination of the orbit of approximately 35 degrees explains the relatively small RV signal.

Subjects: subject: 540 Chemie

description: A new and simple chemical method for deposition of thin blue films composed of Prussian Blue and N-substituted polypyrroles on nonconductive supports is presented. It is found that only pyrroles which are difficult to polymerize can be used for the preparation of such films. The resulting composite films were examined by SEM-EDAX, vis−NIR, and IR spectroscopy. The films are stable, thin, homogeneous, and optically transparent. The absorption maxima are at 720 nm, and spectral changes can be monitored using semiconductor light sources and detectors. The composite films are shown to be suitable for optical determination of pH over the pH 5−9 range because their absorbance strongly depends on pH in the physiological pH range. However, they undergo irreversible spectral changes if exposed to pH's >9. The films represent an alternative to indicator-based pH sensor materials because they do not require a dye to be immobilized. The pH measurements are highly reproducible, reversible in the physiological range, and not affected by ionic strength, alkaline cations, and typical oxidants and reductants.

Testing protocol for evaluating amenability of ores to HPGR crushing for heap leaching
Creators: name: Moghadam Zadeh, Sanaz
Publisher: name: University of British Columbia
Year: 2017

description: Finer particle size distribution (PSD) and generation of more microcracks obtained by the use of high pressure grinding rolls (HPGR) are believed to be the major reasons for metal recovery improvement by heap leaching. Finer PSD increases the surface area of the particles, which are in contact with the leach solution and improves recovery. Microcracks in HPGR materials result in improved penetration of leach solution into the grains and thus metal recovery. The objective of this work is to develop a better understanding of ores crushed by HPGR and cone crusher, in terms of microcracks and PSD, and assess the benefits of using HPGR for heap leach projects. The test results can be used in the early stages of the project to develop an initial understanding of the benefits of utilizing HPGR in the comminution circuits for heap leaching. Gold oxide, copper sulfide and copper/gold sulfide samples were used in this research. Laboratory tests including PSD analysis, scanning electron microscope (SEM), slake durability, Helium (He) pycnometry, nitrogen gas adsorption, water absorption and column tests were used to evaluate the changes in the PSD, microcracks morphology, mechanical stability, porosity, exposed surface area, water absorption capacity and unsaturated flow behavior of the samples. Finally, modeling by HYDRUS was conducted to investigate the hydraulic behavior of the crushed ores. PSD analysis showed finer size distribution for HPGR materials, independent of the ore types. Lower slake durability indices, higher porosities, larger surface areas, higher water absorption values and residual water degree were obtained for HPGR’s materials in comparison with the cone crusher’s. Computer modeling showed lower unsaturated hydraulic conductivity for HPGR samples. Estimation of the microcracks percentage over the total porosity indicated higher values for HPGR samples. Percentage of water inside microcracks and on particle surfaces over the water remaining between particles was higher in most HPGR crushed samples. Finally, a time efficient testing protocol for evaluating the amenability of HPGR to provide ore having the preferred characterization for heap leaching is designed.

description: The photoperiod, which is the length of the light period in the diurnal cycle of 24 h, is an important environmental signal. Plants have evolved sensitive mechanisms to measure the length of the photoperiod. Photoperiod sensing enables plants to synchronize developmental processes, such as the onset of flowering, with a specific time of the year, and enables them to alleviate the impact of environmental stresses occurring at the same time every year. During the last years, the importance of the photoperiod for plant responses to abiotic and biotic stresses has received increasing attention. In this review, we summarize the current knowledge on the signaling pathways involved in the photoperiod-dependent regulation of responses to abiotic (freezing, drought, osmotic stress) and biotic stresses. A central role of GIGANTEA (GI), which is a key player in the regulation of photoperiod-dependent flowering, in stress responses is highlighted. Special attention is paid to the role of the photoperiod in regulating the redox state of plants. Furthermore, an update on photoperiod stress, which is caused by sudden alterations in the photoperiod, is given. Finally, we will review and discuss the possible use of photoperiod-induced stress as a sustainable resource to enhance plant resistance to biotic stress in horticulture.

description: We present the first optical pH sensor with luminescence decay times longer than 1 μs. It is based on radiationless energy transfer from a luminescent ruthenium(II) complex as the donor to a colored pH indicator as the acceptor. The metal−ligand complex ruthenium(II) tris-4,4‘-diphenyl-2,2‘-bipyridyl was selected as the donor, and bromothymol blue and a reactive azo dye were selected as pH-sensitive acceptors. Strategies for co-immobilization of transition metal complexes and pH indicators into a hydrogel matrix were evaluated and discussed. pH transition intervals between 7 and 9 allow the measurement in the physiological range and also under marine conditions. Signal changes of up to 50% over 2.5 pH units are observed, depending on the respective acceptor content in the sensing film. Luminescence lifetime measurements of the sensing films were performed in the frequency domain with a blue LED as the light source. The effect of molecular oxygen (acting both as a quenching and a bleaching agent, thereby limiting the accuracy and the long-term stability of such sensors) was found to be crucial for practical applications. Since leaching of the acceptor also limits the stability of the sensing films, several strategies to reduce this effect were evaluated.

description: Direct optical activation of microbial rhodopsins in deep biological tissue suffers from ineffective light delivery because visible light is strongly scattered and absorbed. NIR light has deeper tissue penetration, but NIR-activation requires a transducer that converts NIR light into visible light in proximity to proteins of interest. Lanthanide-doped upconversion nanoparticles (UCNPs) are ideal transducer as they absorb near-infrared (NIR) light and emit visible light. Therefore, UCNP-assisted excitation of microbial rhodopsins with NIR light has been intensively studied by electrophysiology technique. While electrophysiology is a powerful method to test the functional performance of microbial rhodopsins, conformational changes associated with the NIR light illumination in the presence of UCNPs remain poorly understood. Since UCNPs have generally multiple emission peaks at different wavelengths, it is important to reveal if UCNP-generated visible light induces similar structural changes of microbial rhodopsins as conventional visible light illumination does. Here, we synthesize the lanthanide-doped UCNPs that convert NIR light to blue light. Using these NIR-to-blue UCNPs, we monitor the NIR-triggered conformational changes in sensory rhodopsin II from Natronomonas pharaonis (NpSRII), blue light-sensitive microbial rhodospsin, by FTIR spectroscopy. FTIR difference spectrum of NpSRII was recorded under two different excitation conditions: (ⅰ) with conventional blue light, (ⅱ) with UCNP-generated blue light upon NIR excitation. Both spectra display similar spectral features characteristic of the long-lived M photointermediate state during the photocycle of NpSRII. This study demonstrates that NIR-activation of NpSRII mediated by UCNPs takes place in a similar way to direct blue light activation of NpSRII.

The use of three pairs of primers specific for genomic sequences coding for the two forms of EBV nuclear antigen (EBNA), 2A and 2B, and for a DNA sequence from the BamZ/BamR region allows the reliable and rapid detection of type A and B viruses in as little as 1000 EBV positive cells.
Nocturnal Brain Activity Differs with Age and Sex: Comparisons of Sleep EEG Power Spectra Between Young and Elderly Men, and Between 60–80-Year-Old Men and Women

description: Purpose: Quantification of nocturnal EEG activity has emerged as a promising extension to the conventional sleep evaluation approach. To date, studies focusing on quantitative sleep EEG data in relation to age and sex have revealed considerable variation across lifespan and differences between men and women. However, sleep EEG power values from elderly individuals are still rare. The present secondary analysis aimed to fill this gap. Participants and Methods: Sleep EEG data of 30 healthy elderly males (mean age +/- SD: 69.1 +/- 5.5 years), 30 healthy elderly females (67.8 +/- 5.7 years), and of 30 healthy young males (25.6 +/- 2.4 years) have been collected in three different studies with the same experimental design. Each individual contributed three polysomnographic recordings without any intervention to the analysis. Sleep recordings were performed and evaluated according to the standard of the American Academy of Sleep Medicine. Sleep EEG signals were derived from 19 electrode sites. Sleep-stage specific global and regional EEG power were compared between samples using a permutation-based statistic in combination with the threshold-free cluster enhancement method. Results: The present results showed pronounced differences in sleep EEG power between older men and women. The nocturnal EEG activity of older women was generally larger than that of older men, confirming previously reported variations with sex in younger individuals. Aging was reflected by differences in EEG power between young and elderly men for lower frequencies and for the sleep spindle frequency range, again consistent with prior studies. Conclusion: The findings of this investigation complement those of earlier studies. They add to the understanding of nocturnal brain activity manifestation in senior adulthood and show how it differs with age in males. Unfortunately, the lack of information on young women prevents a similar insight for females.
Realizing the Self-Determination Goals of Indigenous People in Genetics Research

description: Self-determination and tribal sovereignty are core concepts in the lives and histories of Indigenous Peoples. Within the United States, the peoples of the American Indian and Alaska Native tribes are recognized as both a racial group and a political entity. As of April 2021, the United States Bureau of Indian Affairs federally recognizes 574 tribes as Indian entities that are eligible to receive services from the United States. The U.S. Constitution recognizes tribes as sovereign nations with the right to self-determination and grants Congress the authority to interact with Indian tribes. This right to self-determination includes authority over how and what type of research may be conducted within tribal communities and how, when, and who controls data access, use, and reporting on results. This collection provides an introduction to the ELSI literature at the intersection of genomics and Indigenous Peoples in clinical, public health, and community contexts. In the United States, a history of unethical research practices, assimilationist policies, eugenics campaigns, forced removal, and genocide complicate the relationships between Indigenous People and the genomic sciences. There is an emphasis on individual autonomy in U.S. medical ethics, with these principles reinforced in the Belmont Report and the 2018 revised Common Rule. However, given the small numeric size of some tribes, researchers who collect tribal affiliation data are capable of using an individual’s genomic information to make statistical inferences about their entire tribe. As a result of these unique circumstances, precision medicine and genomic research with Indigenous Peoples have inherent legal and ethical dimensions that concern data storage, ownership, access and consent, and intellectual property rights. Practical considerations about how data are used in the context of research, policy, and practice must be grounded within Indigenous spirituality, social ties, histories of scientific exploitation and bio-colonialism, and Indigenous-led and responsive community based participatory research.

description: In the present work a two-component dark matter model is studied adopting the degenerate scenario in the R-parity conserving NMSSM. The gravitino LSP and the neutralino NLSP are extremely degenerate in mass, avoiding the BBN bounds and obtaining a high reheating temperature for thermal leptogenesis. In this model both gravitino (absolutely stable) and neutralino (quasi-stable) contribute to dark matter, and direct detection searches for neutralino are discussed. Points that survive all the constraints correspond to a singlino-like neutralino.

description: A new optical sensor for urea determination is presented. It is based on the enzymatic reaction with urease, which is first photoimmobilized with polyacrylamide onto a chemically polymerized polypyrrole (PPy) film. The main advantage of this sensor is that no indicator dye or pH indicator is needed, because PPy itself acts as the support and the indicator. These PPy films show an absorbance spectrum in the near IR range which is pH dependent. The variation of absorbance is thus directly related to the change of pH caused during the enzymatic reaction, which is also dependent on the urea concentration. The linear range of the sensor is from 0.06 to 1 M of urea, which is the common level of urea concentration found in blood and urine samples.

description: Nucleic acid hybridization is widely used for scientific applications but essentially restricted to specialized laboratories. The use of recombinant m 13 phages as hybridization probes (Hu and Messing (1980) Gene 17, 271; Messing (1983) Methods Enzymol. 101, 20) offers a considerable advantage over the commonly used recombinant plasmids as the preparation of the DNA probe is very simple and it can easily be labeled directly, e.g. with isotopes with long half-life like 125I (Commerford (1971) Biochemistry 10, 11 (1983); Gu et al. (1983) Cancer (China) 2, 129; Han and Harding (1983) Nucleic Acids Res. 11, 14) and used for hybridization. However, as the application of nucleic acid hybridization for diagnostic and epidemiological purposes becomes almost unavoidable, the logistic problems of keeping numerous individually labeled hybridization probes increase considerably and may reach prohibitory levels in less well-equipped laboratories. In a new sandwich technique, the first step involves hybridization with an unlabeled recombinant m 13 DNA carrying an insert of the desired specificity. In a second step a universally usable labeled probe directed against the m 13 part of the recombinant phage DNA is applied. This reduces considerably the problems of preparing and keeping multiple labeled probes in stock.

In contrast, for MA/IgA antibody, 58.3% of NPC patients were positive with a GMT of 1:7.3 and none of the normal individuals were positive. There was no difference in the detection of antibodies to EBV MA when other P3HR-1 or B95-8 cell lines, differing in their major membrane antigen, were used.

description: The ability to make electrical contact to single molecules creates opportunities to examine fundamental processes governing electron flow on the smallest possible length scales. We report experiments in which we controllably stretch individual cobalt complexes having spin S = 1, while simultaneously measuring current flow through the molecule. The molecule's spin states and magnetic anisotropy were manipulated in the absence of a magnetic field by modification of the molecular symmetry. This control enabled quantitative studies of the underscreened Kondo effect, in which conduction electrons only partially compensate the molecular spin. Our findings demonstrate a mechanism of spin control in single-molecule devices and establish that they can serve as model systems for making precision tests of correlated-electron theories.

Narrating intimate partner violence : reclaiming Indigenous women's voices
Creators: name: Vu, Chen
Publisher: name: University of British Columbia

description: Statistics Canada (2009) indicates Indigenous women are at the highest risk of intimate partner violence (IPV) as they experience it at rates three times higher than others. Research on this topic is often detached from the community, thereby, limiting women's ability to assert their voices. There also remains crucial gaps in knowledge on factors that attribute to Indigenous women ending the cycle of IPV. Thus, this research aims to create space for Indigenous women to share their stories and voice their own reflections on the process of how they ended IPV in their lives, in a way that is more empowering and meaningful. Recruitment was conducted through snowball sampling, partaking in community events, and by sending out posters and letters of invitation to organizations. Using a traditional Indigenous practice within a collaborative focus group narrative design, a sharing circle was facilitated with a group of five Indigenous women over the age of 18. In the circle women shared their stories, engaged in discussion, and participated in a oral analysis of the themes in their individual stories, as well as the collective narratives. The identification of themes by the participants themselves, allowed for the participants voices' to be expressed within the results of the research itself. Following this, a secondary six-step thematic analysis was conducted by the researcher in order to situate the data within the themes as described by the participants. All findings were reported back to participants for validity checks to ensure collaboration in all stages of the research. Results of this research will ultimately inform counselling and other professional practices as it will add to the foundation of knowledge needed in order for the resolution of IPV against Indigenous women.

description: Vietnamese English teachers (VETs), especially those working in high schools, are under public pressure because of their poor performances in national English proficiency assessments (Dudzik & Nguyen, 2013). As Le (2007) suggests, this is widely seen as the main reason why Vietnamese English learners have poor learning outcomes. Research shows, however, that it is the effectiveness of instruction that plays a crucial role in determining the success of language students (Richards, 1987; Richards & Nunan 1990; Burns, 1992). Given this dilemma between proficiency and instructional ability, it is necessary to investigate how VETs perceive their own situations and what they think can help improve their teaching. Little is known about this in the Vietnamese context (Trao & Ngoc, 2015).
This thesis follows a qualitative approach within an interpretive paradigm to investigate perspectives of a range of experienced high school VETs on issues related to the making of an effective English teacher (EET). Data were collected through six main research instruments (i.e., questionnaires, individual interviews, group interviews, focus-group interviews, classroom observations, and reflective tasks) and were analysed thematically. Several frameworks and theories (i.e., Korthagen’s (2004) ‘Onion Model’; Borg’s (2006) teacher cognition; Farrell’s (2015) reflective practice) were employed either inductively or deductively to help interpret the data.
The study’s findings shift our understanding of what makes an EET from simply referring to a checklist of explicit competencies (e.g., Mullock, 2003; Tsui, 2003; Park & Lee, 2006) to considering the combination of both explicit competencies as observable features and others aspects such as teachers’ beliefs and cognition as unobservable features. Drawing from the findings, three innovative EET models (i.e., EET model; EET support model; and EET strategies model) were developed to facilitate and better inform teacher educators, teachers, and other stakeholders in their roles preparing successful, effective VETs.

description: Background: The COVID-19 pandemic has led to a wide range of stressors related to depressive symptoms. Prevention measures like physical distancing have burdened the general population, especially in highly urbanized areas. However, little is known about the associations between pandemic-related stressors, coping strategies, and depressive symptoms in highly urbanized vs. less urbanized environments. Methods: Participants were recruited in a cross-sectional online survey in Germany. Propensity score matching yielded a matched sample of city (n = 453) and town (n = 453) inhabitants. Depressive symptoms, COVID-19-related stressors, and coping strategies were compared between cities and towns. Multiple regression analysis was performed to determine associations between pandemic-related stressors and depressive symptoms for the two groups separately. Results: City inhabitants showed significantly higher depression scores than town inhabitants (t = 2.11, df = 897.95, p = 0.035). Seven coping strategies were more often used by the city sample. Depressive symptoms were associated with “restricted physical social contact” and “difficult housing conditions” (adjusted R2= 0.19, F[9,443] = 12.52, p < 0.001) in city inhabitants, and with “fear of infection” and “difficult housing conditions” (adjusted R2= 0.20, F[9,443] = 13.50, p < 0.001) in town inhabitants. Limitations: The data were collected at the end of the first wave and represent a snapshot without causal inferences. Pandemic-related stressors were measured with a newly developed scale. Conclusion: Depressive symptoms, perceived stressors, and approach/avoidance coping strategies differed between city vs. town inhabitants. These differences should be considered in policy-making and mental health care.
Testing Mass Loss in Large Magellanic Cloud Cepheids using Infrared and Optical Observations II. Predictions and Tests of the OGLE-III Fundamental-Mode Cepheids

description: In this article, we test the hypothesis that Cepheids have infrared excesses due to mass loss. We fit a model using the mass-loss rate and the stellar radius as free parameters to optical observations from the OGLE-III survey and infrared observations from the 2MASS and SAGE data sets. The sample of Cepheids have predicted minimum mass-loss rates ranging from zero to $10^{-8}M_\odot$ $yr^{-1}$, where the rates depend on the chosen dust properties. We use the predicted radii to compute the Period-Radius relation for LMC Cepheids, and to estimate the uncertainty caused by the presence of infrared excess for determining angular diameters with the infrared surface brightness technique. Finally, we calculate the linear and non-linear Period-Luminosity (P-L) relations for the LMC Cepheids at VIJHK + IRAC wavelengths and we find that the P-L relations are consistent with being non-linear at infrared wavelengths, contrary to previous results.

description: To assess the toxic potential of the alkaloids, a quantification method is necessary. An ion pair extraction method was used for quantitative fluorometric determination of vincamine, protopine and all contained alkaloids in the mother tinctures of Vinca minor and Fumaria officinalis. The non-fluorescent alkaloids were transformed into an ion pair with sodium-9,10-dimethoxy-anthracene-sulfonate and then fluorometrically determined and quantified in this study. The applicable ion pair was extracted in a suitable organic solvent, where dichloromethane has proven to be beneficial. Conditions for the ion pairing and fluorometric quantification are given. The recovery rate was used to investigate the quality of determinability and the influence of the mother tincture matrix. The method was applied to determine the concentration of protopine in the range 0.1 – 15 μg/ml and of vincamine in the range of 0.5 – 20 μg/ml. The limit of detection was < 0.3 μg/ml, and the limit of quantification < 0.9 μg/ml for both alkaloids.

description: Background: Primary biliary cholangitis (PBC) is a chronic liver disease that can lead to liver fibrosis and cirrhosis. Two-dimensional shear wave elastography (2D-SWE) is a modern technique for fibrosis assessment. However, data regarding its performance in PBC is sparse. We aimed to characterize severity of liver disease in PBC patients using non-invasive 2D-SWE and the new methods of attenuation imaging (ATI) and shear wave dispersion imaging (SWD). Methods: Twenty two PBC patients were examined with 2D-SWE, SWD and ATI, alongside established non-invasive fibrosis and steatosis assessment methods as well as liver function tests. Results: Median 2D-SWE values were 1.48 m/S (range, 1.14-2.13 m/S) and 6.7 kPa (range, 3.8-14.7 kPa), respectively. Median SWD, ATI, transient elastography (TE) and controlled attenuation parameter (CAP) values were 13.9 m/S/ kHz (range, 11.6-21 m/S/kHz), 0.57 dB/cm/MHz (range, 0.5-0.68 dB/cm/MHz), 7 kPa (range, 3.7-14.6 kPa), and 208 dB/m (range, 107-276 dB/m), respectively. 2D-SWE displayed a significant correlation with spleen length, platelet count, non-invasive fibrosis scores (FIB-4, APRI) and with TE. SWD correlated with alkaline phosphatase (ALP) levels, which is a prognostic marker in PBC. Conclusions: Our findings add further evidence that 2D-SWE is a reliable method for fibrosis assessment in PBC. Even though the cohort size was small, the correlation of SWD with the prognostic marker ALP suggests a potentially valuable role of this new non-invasive method in evaluating liver disease activity in PBC.

description: This article describes the preparation and performance of an optical sensor for continuous measurement of chloride at extracellular (serum) levels (20–200 mM). The sensor is based on dynamic quenching of the fluorescence of lucigenin which was photo-immobilized on a hydrogel. Quenching occurs via a collisional mechanism, and the decrease in fluorescence intensity on exposure to 100mM chloride typically is -60%. It allows the determination of chloride in the 1 to 200mMconcentration range, with a precision of ±3mM at 120 mM. Bromide, iodide and salicylate act as interferents, while the effect of pH and oxygen is negligibly small. The sensor displays strong fluorescence intensity, excellent reproducibility, longterm stability, response times in the order of 2–5 min, and is used in a commercial serum and blood chloride analyzer.
