Žižek, Slavoj (1949–)
Authors: Dean Jodi 
Published: August 2023

Abstract

Slavoj Žižek was born in Ljubljana, Slovenia (at the time part of Yugloslavia) in 1949. He studied philosophy and psychoanalysis and was active in the intellectual dissident scene, part of the critical ferment preceding the collapse of Yugoslavia. Unable to find employment as an academic, Žižek worked as a clerk for the Central Committee of the League of Slovene Communists before securing a position as a researcher at the Institute for Sociology in Ljubljana in 1979. Much of his intellectual output in this period was connected with the projects of a close group of theorists engaged in rereading Hegel and Althusser through the psychoanalytic theory of Jacques Lacan, most notably Mladen Dolar and Alenka Zupančič. The group had various publishing ventures, including a book series,
Analecta
, and a journal,
Problemi
. Žižek also wrote a regular column for a popular weekly,
Mladina
. In 1990, he ran for a seat in the four‐member presidency of the Republic of Slovenia as a member of the Liberal Democratic Party (which opposed communism and nationalism), coming in fifth.

Published: August 2023

AbstractSodium‐ion batteries (SIBs) are a viable alternative to meet the requirements of future large‐scale energy storage systems due to the uniform distribution and abundant sodium resources. Among the various cathode materials for SIBs, phosphate‐based polyanionic compounds exhibit excellent sodium‐storage properties, such as high operation voltage, remarkable structural stability, and superior safety. However, their undesirable electronic conductivities and specific capacities limit their application in large‐scale energy storage systems. Herein, the development history and recent progress of phosphate‐based polyanionic cathodes are first overviewed. Subsequently, the effective modification strategies of phosphate‐based polyanionic cathodes are summarized toward high‐performance SIBs, including surface coating, morphological control, ion doping, and electrolyte optimization. Besides, the electrochemical performance, cost, and industrialization analysis of phosphate‐based polyanionic cathodes for SIBs are discussed for accelerating commercialization development. Finally, the future directions of phosphate‐based polyanionic cathodes are comprehensively concluded. It is believed that this review can provide instructive insight into developing practical phosphate‐based polyanionic cathodes for SIBs.
Polymer and photo‐selective covers on plant and fruit development: A review
Authors: Pandey Gareema , Parks Sophie , Thomas Richard G. 
Published: August 2023

AbstractGrowers have increasingly adopted protected cropping in tunnels or greenhouses to ensure sustainability and continuous crop productivity against a backdrop of climate change. The predominant types of covers used in controlled‐environment agriculture are polymer‐based shade nets or structures covered with polymer sheets. These have three main functions: (1) physical protection from birds, hail, and excessive radiation; (2) modification of the environment by controlling humidity, shade, and temperature; and (3) increasing the proportion of diffuse light. In order to address concerns regarding the amounts of useful light potentially blocked by these covers, researchers and growers have suggested several innovative solutions that involve altering the light received by plants. This includes supplementation of artificial illumination, filtering solar radiation with colored films, or altering the incident spectrum with spectral‐shifting covers containing light‐emitting fluorescent compounds embedded within a polymer matrix. In principle, any of these methods have the potential to selectively modify the spectrum of incident light and subsequently induce plant physiological responses, resulting in increased crop yield, improved fruit quality, and reduced susceptibility to pests and diseases. This review focuses on the benefits offered by passive covers in terms of their variable shading and light transmittance properties and their effects on vegetative growth and fruit development in various crops. It is anticipated that through a better understanding of photo‐selective covers in protected cropping, primary producers will be better equipped to make informed decisions regarding their deployment and thereby achieve better yields and more nutritious produce from their crops.

AbstractA rapid and sensitive strategy was proposed for the detection of fluoranthene (FL), which is a polycyclic aromatic hydrocarbon (PAH), in water samples. In this work, syringe solid‐phase extraction (SPE) combined with solid‐phase fluorescence spectrometry was used to determine FL in PAHs polluted environmental samples. The fluorescence signals were directly monitored on the membrane surface after FL was enriched by syringe SPE. Under the optimal conditions, the proposed method showed a linear relationship in the concentration range 2–50 μg/L with a correlation coefficient (R2) of 0.998, and the limit of detection was 0.143 μg/L. The recoveries varied from 93.47% to 109.81% in the actual samples, with the relative standard deviations (n = 3) ranging from 2.06% to 6.32%. According to the results, the established method can be applied in the field of rapid detection as it is fast, simple, portable, and highly sensitive, and has strong anti‐interference.

AbstractThe reactivity of hexamethylcyclotrisiloxane (D3) towards BeCl2, BeBr2, BeI2 and [Be3Ph6]3 was investigated. While BeCl2 only showed unselective reactivity, BeBr2, BeI2 and [Be3Ph6] cleanly react to the trinuclear complexes [Be3Br2(OSiMe2Br)4], [Be3I2(OSiMe2I)4] and [Be3Ph2(OSiMe2Ph)4]. These unprecedented bromide, iodide and phenyl transfer reactions from a group II metal onto silicon offer a versatile access to previously unknown diorgano bromo and iodo silanolates.

AbstractObjectiveThe present study aimed to explore the relationship between difficulties in emotion regulation and deficits in inhibitory control, and the role of these processes in eating psychopathology in a non‐clinical sample. We also explored the specificity in which deficits in inhibitory control may underlie eating psychopathology, namely whether they can be conceptualised as context specific or more extensive in nature.MethodParticipants were 107 healthy individuals recruited at a major Portuguese university, aged between 18 and 43 years‐old (M = 21.23, SD = 4.79). Two computerised neuropsychological tasks (i.e., emotional go/no‐go and food go/no‐go tasks) were used to assess response inhibition in the presence of general versus context‐specific stimuli. A set of self‐report measures was used to assess variables of interest such as emotion regulation and eating psychopathology.ResultsResults indicated higher response inhibition deficits among participants with higher difficulties in emotion regulation comparing to those with lower difficulties in emotion regulation, particularly in the context of food‐related stimuli. In addition, the relationship between difficulties in emotion regulation and eating psychopathology was moderated by inhibitory control deficits in both the context of food and pleasant stimuli.ConclusionsThe present findings highlight inhibitory control as an important process underlying the relationship between difficulties in emotion regulation and eating psychopathology in non‐clinical samples. Findings have important implications for clinical practice and the prevention of eating psychopathology in healthy individuals and individuals with eating disorders.

Published: August 2023

AbstractAn efficient three‐step synthesis of (1R)‐1‐(4‐bromophenyl)‐2,2,2‐trifluoroethan‐1‐amine hydrochloride (1) starting from inexpensive and readily available starting materials was developed. The sequence features a highly diastereoselective trifluoromethylation of a chiral sulfinimine using the Rupert–Prakash reagent TMSCF3 in combination with K3PO4 as an initiator. The diastereomeric purity of the resulting sulfinamide was further improved by direct precipitation of the desired diastereomer from the reaction mixture upon addition of water. The chiral auxiliary was then removed under acidic conditions, resulting in the isolation of chiral benzylamine 1 as its hydrochloride salt in 71 % overall yield and excellent purity (LC/MS: >99 % a/a; e.r.=99 : 1).

AbstractIntroductionPharmacogenomics (PGx) testing uses a patient's deoxyribonucleic acid (DNA) profile to tailor medications with the goal of preventing adverse drug reactions and improving pharmacotherapy outcomes. Despite the availability of evidence‐based guidelines that assist with interpretation of PGx results, PGx testing has not been widely adopted.ObjectiveTo describe how a multidisciplinary PGx clinic was implemented within the University of Pennsylvania Health System (Penn Medicine) including the clinical workflow, challenges to implementation, and future directions.MethodsThis project qualified as Quality Improvement by the University of Pennsylvania's Institutional Review Board and adheres to the Standards for Quality Improvement Reporting Excellence (SQUIRE) 2.0 guidelines. Clinic metrics were collected from February 2019 until December 2022. Data collected included patient demographics; the timing of PGx test ordering and appointments; number and frequency of actionable PGx phenotypes; number of current or historical medications impacted by PGx test results; and patient's out‐of‐pocket cost for PGx test.ResultsOf the 69 patients included, the majority were female (58%), white (84%), with a mean age of 48 years. The overall time between the dates of the PGx test order and clinic visit was 37 days. The time between the dates of the PGx test order and the PGx test results were generated was 18 days. All patients had at least one actionable PGx phenotype and 74% had three or more. The most frequent actionable phenotypes were found in the cytochrome P450 PC19 (CYPC19) (60%) and CYP2D6 (58%) genes. The percentage of patients that had drug‐gene interactions that affected their current medications and explained historical medication intolerances were 25% and 17%, respectively. Out‐of‐pocket costs were less than $300 for most patients who had a PGx test ordered by the clinic physician.ConclusionThis paper has established a sustainable PGx clinic workflow with dedicated personnel. In the future we intend to increase the availability of our services.

Published: August 2023

AbstractNanofiber membranes (NFMs), which have an extracellular matrix‐mimicking structure and unique physical properties, have garnered great attention as biomimetic materials for developing physiologically relevant in vitro organ/tissue models. Recent progress in NFM fabrication techniques immensely contributes to the development of NFM‐based cell culture platforms for constructing physiological organ/tissue models. However, despite the significance of the NFM fabrication technique, an in‐depth discussion of the fabrication technique and its future aspect is insufficient. This review provides an overview of the current state‐of‐the‐art of NFM fabrication techniques from electrospinning techniques to postprocessing techniques for the fabrication of various types of NFM‐based cell culture platforms. Moreover, the advantages of the NFM‐based culture platforms in the construction of organ/tissue models are discussed especially for tissue barrier models, spheroids/organoids, and biomimetic organ/tissue constructs. Finally, the review concludes with perspectives on challenges and future directions for fabrication and utilization of NFMs.

AbstractPurposeTo ultimately make accurate and precise fetal noninvasive oxygen saturation (sO2) measurements by T2‐prepared bSSFP more widely available by systematically assessing error sources in order to potentially reduce perinatal mortality in cardiovascular malformations and fetal growth restriction.MethodsT2‐prepared bSSFP data were acquired in phantoms; in flowing blood in adults in the superior sagittal sinus, ascending and descending aorta, and main pulmonary artery; and in the fetal descending aorta and umbilical vein. T2 was assessed in relation to T2 two‐ or three‐parameter curve‐fitting techniques, SSFP readout, refocusing time delay (τ), constant and pulsatile blood flow, and impact of T1 recovery. Further, fetal T2 and sO2 variability were quantified in the descending aorta and umbilical vein in healthy fetuses and fetuses with cardiovascular malformation (gestational weeks 32–38).ResultsIn phantoms, three‐parameter fitting was accurate irrespective of phase FOV (<4 ms; i.e., <2%), and T2 was overestimated (up to 23 ms/10%; p = 0.001) beyond ±30 Hz off‐resonance. In the adult aorta, T2 was underestimated during higher blood flow velocities and pulsatility for τ = 16 ms (−41 ms/−17%; p = 0.008). In fetuses, two‐parameter fitting overestimated T2 compared with three‐parameter fitting (+33 ms/+18%; p = 0.03). T2 variability was 18 ms/15% in the fetal descending aorta and 28 ms/14% in the umbilical vein. The resulting estimated sO2 variability was ∼10% (15% of sO2 value) in the fetal descending aorta.ConclusionsErrors due to T2‐fitting techniques, off‐resonance, flow velocity, and insufficient T1 recovery between image acquisitions could be mitigated by using three‐parameter fitting with included saturation‐prepared images approximating infinite T2‐preparation time, adequate shimming covering the fetus and placenta, and by modifying acquisition parameters. Variability in fetal blood T2 and sO2, however, indicate that it is currently not feasible to use these methods for prediction of disease.

Published: August 2023

AbstractPurposeIn resting‐state fMRI (rs‐fMRI), the global signal average captures widespread fluctuations related to unwanted sources of variance such as motion and respiration, as well as widespread neural activity; however, relative contributions of neural and non‐neural sources to the global signal remain poorly understood. This study sought to tackle this problem through the comparison of the BOLD global signal to an adjacent non‐brain tissue signal, where neural activity was absent, from the same rs‐fMRI scan obtained from anesthetized rats. In this dataset, motion was minimal and ventilation was phase‐locked to image acquisition to minimize respiratory fluctuations. Data were acquired using three different anesthetics: isoflurane, dexmedetomidine, and a combination of dexmedetomidine and light isoflurane.MethodsA power spectral density estimate, a voxel‐wise spatial correlation via Pearson's correlation, and a co‐activation pattern analysis were performed using the global signal and the non‐brain tissue signal. Functional connectivity was calculated using Pearson's linear correlation on default mode network (DMN) regions.ResultsWe report differences in the spectral composition of the two signals and show spatial selectivity within DMN structures that show an increased correlation to the global signal and decreased intra‐network connectivity after global signal regression. All of the observed differences between the global signal and the non‐brain tissue signal were maintained across anesthetics.ConclusionThese results show that the global signal is distinct from the noise contained in the tissue signal, as support for a neural contribution. This study provides a unique perspective to the contents of the global signal and their origins.

AbstractPurposeTo develop a new MRI method, entitled alternating Look‐Locker (aLL), for quantitative , , and 3D mapping.MethodsA Look‐Locker scheme that alternates magnetization from +Z and −Z axes of the laboratory frame is utilized in combination with a 3D Multi‐Band Sweep Imaging with Fourier Transformation (MB‐SWIFT) readout. The analytical solution describing the spin evolution during aLL, as well as the correction required for segmented acquisition were derived. The simultaneous and mapping are demonstrated on an agar/saline phantom and on an in‐vivo rat head. relaxation was achieved by cyclically applying magnetization preparation (MP) modules consisting of two adiabatic pulses. values in the rat brain in‐vivo and in a gadobenate dimeglumine (Gd‐DTPA) phantom were compared to those obtained with a previously introduced steady‐state (SS) method.ResultsThe accuracy and precision of the analytical solution was tested by Bloch simulations. With the application of MP modules, the aLL method provides simultaneous and maps. Conversely, without it, the method can be used for simultaneous and mapping. values were similar with both aLL and SS techniques. However, the aLL method resulted in more robust quantitative mapping compared to the SS method. Unlike the SS method, the aLL method does not require additional scans for generating maps.ConclusionThe proposed method offers a new flexible tool for quantitative mapping of , , and . The aLL method can also be used with readout schemes different from MB‐SWIFT.
High Selective Detection of Trace Lead Ions via Substitution‐triggered Chemiluminescence Enhancement
Authors: Li Hongrui , Hou Yue 
Published: August 2023

AbstractLead ion (Pb2+) is a high‐hazardously heavy metal ion in surroundings that even ppb level can cause mental decline and behavioral difficulties especially in children. However, the recognition and detection of Pb2+ are still challenging. Here, a high selective and ultra‐sensitive chemiluminescence (CL) method was established based on the substitution mechanism between Pb2+ and the metal–organic framework – Cu‐MOF‐74. Pb2+ can specifically substitute Cu active sites in Cu‐MOF‐74 and released Cu sites, strongly amplifying the CL emission of the luminol‐hydrogen peroxide (H2O2) system. A linear response for Pb2+ detection in the range of 0.5–50 nM with a detection limit of 0.3 nM was realized. Moreover, the proposed method was successfully implemented on a paper‐based analytical device with favorable fabrication and operational features for Pb2+ determination in water samples. It offers a new strategy to design high selective and sensitive sensors for the heavy metal ions monitoring.

ABSTRACTSerous surface papillary borderline ovarian tumor (SSPBOT) is a distinct subtype of serous borderline ovarian tumor characterized by solid tissue deposition confined to the ovarian surface. Because SSPBOT is rare, there are few published reports on the ultrasonographic features of this condition. In this retrospective study, we investigated 12 cases of SSPBOT. Ultrasound imaging of SSPBOT showed grossly normal ovaries that were encased partially or wholly by tumor deposits that were confined to the surface, with clear demarcation between normal ovarian tissue and surrounding tumors. Color Doppler imaging demonstrated the ‘fireworks sign’ in all cases of SSPBOT, corresponding to an intratumoral vascular bundle originating from the ovarian vessels and supplying hierarchical branching blood flow to the surrounding tumor. No patient with ovarian high‐grade serous carcinoma showed these morphological and Doppler features. In our series, the fireworks sign appeared to be a characteristic feature of SSPBOT that could facilitate correct identification of this tumor. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

AbstractBackgroundDog bites to people are a serious public health problem. Limited information exists at the country level in Latin America. The COVID‐19 pandemic changed people's lifestyles and their relationship with pets, and this could potentially affect the incidence of dog bites injuries.ObjectiveThe main objectives of our study were to determine the prevalence of dog‐bite injuries in Uruguay from 2010 to 2020 and to compare the prevalence in 2020 to that of pre‐pandemic years.MethodsCross‐sectional study. Dog‐bite notifications for the 2010 and 2020 period were analysed using data from the Uruguayan Ministry of Public Health.ResultsThe annual dog‐bite injury rate for the 2010–2020 period was 87.51 per 100,000 people. The frequency of bites varied with the victims’ sex, with males accounting for 51.8% of the bites (p < 0.0001), and with age, with a higher frequency of bites in the ≤14 years old age group (p < 0.01). The frequency of dog bites was also higher in spring and summer than in autumn (p < 0.0001). There was no statistical difference in the frequency of dog‐bite injuries when comparing 2020 with the pre‐COVID‐19 pandemic years.ConclusionsIn Uruguay, the frequency of dog‐bite injuries varied with season and with the age and sex of the victim. In the first year of the COVID‐19 pandemic, the number of people bitten by dogs was no different than that of previous years. This is the first study in Latin America to report national rather than regional data and to include all age groups.
