Background
Borderline personality disorder (BPD) is a severe psychiatric disorder conceptualised as a disorder of emotion regulation. Emotion regulation has been linked to a frontolimbic network comprising the dorsolateral prefrontal cortex and the amygdala, which apparently synchronises its activity via oscillatory coupling in the theta frequency range.

Aims
To analyse whether there are distinct differences in theta oscillatory coupling in frontal brain regions between individuals with BPD and matched controls during emotion regulation by cognitive reappraisal.

Method
Electroencephalogram (EEG) recordings were performed in 25 women diagnosed with BPD and 25 matched controls during a cognitive reappraisal task in which participants were instructed to downregulate negative emotions evoked by aversive visual stimuli. Between- and within-group time–frequency analyses were conducted to analyse regulation-associated theta activity (3.5–8.5 Hz).

Results
Oscillatory theta activity differed between the participants with BPD and matched controls during cognitive reappraisal. Regulation-associated theta increases were lower in frontal regions in the BPD cohort compared with matched controls. Functional connectivity analysis for regulation-associated changes in the theta frequency band revealed a lower multivariate interaction measure (MIM) increase in frontal brain regions in persons with BPD compared with matched controls.

Conclusions
Our findings support the notion of alterations in a frontal theta network in BPD, which may be underlying core symptoms of the disorder such as deficits in emotion regulation. The results add to the growing body of evidence for altered oscillatory brain dynamics in psychiatric populations, which might be investigated as individualised treatment targets using non-invasive stimulation methods.

Published: March 2024

Abstract
Diffuse thyroid lipomatosis (DTL) is a rare entity of unknown etiology that can be associated with amyloidosis and rarely, thyrotoxicosis. Here, we present a case of DTL with amyloid deposits and concurrent thyrotoxicosis. A 64-year-old South-Asian woman with a several-year history of an enlarging goiter, unintentional weight loss, and work-up 10 months prior suggestive of thyroiditis presented with a viral syndrome in setting of several weeks of progressive fatigue. Her examination was notable for resting sinus tachycardia and massive painless goiter. Initial work-up revealed nephrotic range proteinuria with hypoalbuminemia, which progressed to end-stage-renal disease, elevated inflammatory markers, and elevated free thyroxine (FT4) with a suppressed thyrotropin. Hemodialysis was initiated. Further testing revealed a negative antithyroid antibody panel, an enlarged fatty thyroid per thyroid ultrasound and neck computed tomography, and normal 24-hour uptake on radioactive iodine uptake scan. Both renal and thyroid core biopsies showed amyloid deposits, with the latter confirming benign adipose tissue with entrapped thyroid follicles. Given her rising FT4 levels and persistent tachycardia, methimazole and atenolol were initiated. FT4 levels nearly normalized after uptitration of methimazole and dosing after dialysis. Although the etiopathogenesis and natural history of DTL remain unclear, we discuss the possible mechanisms of thyrotoxicosis in our patient.

Abstract
Here, we present the case of a 40-year-old man in whom the diagnosis of ectopic adrenocorticotropin (ACTH) syndrome went unrecognized despite evaluation by multiple providers until it was ultimately suspected by a nephrologist evaluating the patient for edema and weight gain. On urgent referral to endocrinology, screening for hypercortisolism was positive by both low-dose overnight dexamethasone suppression testing and 24-hour urinary free cortisol measurement. Plasma ACTH values confirmed ACTH-dependent Cushing syndrome. High-dose dexamethasone suppression testing was suggestive of ectopic ACTH syndrome. Inferior petrosal sinus sampling demonstrated no central-to-peripheral gradient, and 68Ga-DOTATATE scanning revealed an avid 1.2-cm left lung lesion. The suspected source of ectopic ACTH was resected and confirmed by histopathology, resulting in surgical cure. While many patients with Cushing syndrome have a delayed diagnosis, this case highlights the critical need to increase awareness of the signs and symptoms of hypercortisolism and to improve the understanding of appropriate screening tests among nonendocrine providers.
Polarity establishment in the plant zygote at a glance
Authors: Matsumoto Hikari , Ueda Minako 
Published: March 2024

ABSTRACT
The complex structures of multicellular organisms originate from a unicellular zygote. In most angiosperms, including Arabidopsis thaliana, the zygote is distinctly polar and divides asymmetrically to produce an apical cell, which generates the aboveground part of the plant body, and a basal cell, which generates the root tip and extraembryonic suspensor. Thus, zygote polarity is pivotal for establishing the apical-basal axis running from the shoot apex to the root tip of the plant body. The molecular mechanisms and spatiotemporal dynamics behind zygote polarization remain elusive. However, advances in live-cell imaging of plant zygotes have recently made significant insights possible. In this Cell Science at a Glance article and the accompanying poster, we summarize our understanding of the early steps in apical-basal axis formation in Arabidopsis, with a focus on de novo transcriptional activation after fertilization and the intracellular dynamics leading to the first asymmetric division of the zygote.

Published: March 2024

Background Food and drug packaging materials are an integral part of our everyday life. Noxious elements can inadvertently be included in packaging materials in various stages of their production. Adulterants, adhesives, colorants and heavy metal interference are the common sources of contamination in food packaging materials. Heavy metal toxicity has far-reaching ill effects on living organisms. The present study aimed at qualitatively and quantitatively analysing heavy metal content of various materials that are used for food and drug packaging in India. Methods The qualitative detection was done by rapid assay and heavy metals were quantified with the help of inductively coupled plasma-optical emission spectrometry (ICP-OES). A total of thirteen types of food and drug packaging materials were procured from local market and analysed for four heavy metals viz. arsenic (As), vanadium (V), mercury (Hg) and cadmium (Cd). The concentration of each heavy metal in the samples was compared with the permissible values published by the European Council. Results Heavy metals were qualitatively detected in ten out of thirteen samples. Among the ten samples mercury and arsenic were detected the most followed by cadmium and vanadium. Quantitative estimation by ICP-OES showed presence of vanadium and cadmium in ten samples and arsenic and mercury in all the thirteen samples above the permissible range. Conclusions The notable elevation in mercury concentration, followed by cadmium, arsenic and vanadium registering the least, presents a potential health hazard to consumers and compromises the food quality.

Introducción: El dolor lumbar es una condición frecuente en los estudiantes de medicina identificándose diversos factores de riesgo, el objetivo del estudio fue evaluar la asociación entre la presencia de dolor lumbar crónico (DL) y la conducta sedentaria en estudiantes de medicina de una universidad privada.
Materiales y métodos: estudio transversal analítico, prospectivo observacional, participaron 167 encuestados (101 hombres y 66 mujeres). Las mediciones principales fueron la conducta sedentaria y actividad física fueron medidas a través del Cuestionario Mundial sobre Actividad Física (GPAQ); el dolor lumbar crónico se midió con una temporalidad de 12 meses mediante el cuestionario nórdico de Kuorinka de trastornos musculoesqueléticos.
Resultados: La frecuencia de dolor lumbar fue 67,7% y una media de conducta sedentaria de 9.5 horas (D.T: 3,04), el 70.6%, mantiene un nivel de actividad física saludable, se encontró mayor conducta sedentaria asociada a mayor presencia de DL, al análisis multivariado se encontró que para cada hora sentado se aumenta significativamente la probabilidad de padecer DL (OR 1,17: p= 0.013). Los estudiantes que permanecen de 10 a más horas sentados/recostados presentan un aumento de riesgo de padecer dolor lumbar (ORa = 4,13: p= 0.001) frente a los que permanecen menos de 10 horas sentados/recostados.
Conclusión: Se observa que por cada hora en posición sedente/recostado aumenta en 15% la razón de chance de sufrir dolor lumbar crónico en los estudiantes, así como acumular de 10 a más horas al día en posición sedente recostado aumenta significativamente el padecer de dolor lumbar en los últimos 12 meses.
The Ideological Imperative: Corporate Social Responsibility and News Media Coverage of Firms
Authors: Dewan Yasir , Simons Tal , Wernicke Georg 
Published: March 2024

Although prior research attributes news media coverage of firms to the alignment of firm behavior with societal expectations of appropriateness, the appropriateness of firm behavior is judged through an ideological lens. Therefore, the influence of a firm’s behavior on its news media coverage is likely to be contingent on news organizations’ ideology. Focusing on corporate social responsibility (CSR) as the focal firm behavior, we argue that conservative news organizations are less likely to consider CSR an appropriate firm behavior because conservatives view CSR as privileging progressive ideals and as undermining shareholder interests. As such, we hypothesize that compared with other news organizations, conservative news organizations are less likely to cover socially responsible firms positively. This relationship is likely to be strengthened for firms led by conservative chief executive officers and for firms with poor stock market performance. We examined the coverage of the S&P 1500 firms from 2002 through 2011 in U.S. newspapers and found support for our hypotheses that compared with other newspapers, conservative newspapers report less positively about socially responsible firms and that this effect is strengthened for conservative-led firms. In contrast to what we expected, however, we found some evidence that socially responsible firms with a strong stock market performance are, in fact, covered less positively in conservative newspapers. Taken together, our theory and findings contribute to an understanding of how the news media’s ideological heterogeneity shapes the relationship between firm behavior (in our case, CSR) and news media coverage of firms.

Background: This report presents the influence of immunosuppression by new rheumatological therapies on hepatitis E virus infection in a 54-year-old male patient with an anti-synthetase syndrome and treatment with methotrexate and rituximab. Case description: The patient arrived at the Emergency Department with epigastric pain, vomiting and dark urine. Initial examination revealed signs of inflammation and hepatic dysfunction. Subsequent laboratory tests and imaging confirmed acute hepatitis E infection in the context of recent initiation of rituximab therapy. Despite initial suspicion of pancreatitis, subsequent investigations ruled out pancreatic involvement. Treatment with ribavirin, along with supportive measures, led to significant clinical improvement with resolution of jaundice, ascites, and oedema. Conclusions: This case underscores the importance of considering hepatitis E in patients with autoimmune conditions, especially when initiating immunosuppressive therapies, a situation that is not well described in scientific literature and is increasingly common, necessitating proper recognition.
5 Parasequences
Authors: Bohacs K. M. , Lazar O. R. , Demko T. M. 
Published: March 2024

ABSTRACTThis chapter presents parasequences—the next larger and more aerially extensive three-dimensional stratal unit of the stratigraphic hierarchy found consistently across most depositional environments. The parasequence scale is the key scale at which we interpret depositional environments, apply Walther’s Law to recognize significant stratal discontinuities, correlate and construct maps, and make tie-ins with well-log signatures.A parasequence is a distinctive succession of relatively conformable beds and bedsets bounded by surfaces of flooding, abandonment, or reactivation and their correlative surfaces. They can be recognized in a variety of depositional settings through specific and objective attributes of their stratal stacking and bounding surfaces. The definitive interpretation of any particular interval as a parasequence requires two components: (1) recognizing its character in vertical section and (2) establishing its lateral distribution over an area significantly broader than any single component bedset or geomorphic element of the depositional environment (i.e., many hundreds of square kilometers). Although it might be difficult to recognize parasequences in a particular interval or location, they still are extremely likely to exist even there because they appear to be a universal feature of sedimentation.This chapter introduces the general concepts of parasequences, illustrates those concepts with marine-shelfal examples, and provides practical guidelines for recognizing and correlating parasequences. It then discusses common variations in vertical and lateral aspects, presents an application to building quantitative models of depositional environments, and introduces the expression of parasequences in other depositional settings. Recognition of parasequences is essential because they are the building blocks of the next larger scales in the stratigraphic hierarchy: parasequence sets (systems tracts) and depositional sequences, which are discussed in Bohacs et al. (2022b, Chapter 6 this Memoir).The following excerpt from table 12 of Lazar et al. (2022a, Chapter 3 this Memoir, p. 72) places parasequences in their context in the sequence-stratigraphic interpretation workflow:
7 Sequence Sets and Composite Sequences
Authors: Bohacs Kevin , Lazar Remus , Demko Tim , Ottmann Jeff , Potma Ken 
Published: March 2024

ABSTRACTThis chapter presents definitions, recognition criteria, and examples of sequence sets and composite sequences within a sequence-stratigraphic framework. This stratigraphic scale provides useful insights into shale-gas and tight-liquid plays with mudstone reservoirs that can be profitably grouped into four families based on stratal stacking at the sequence-set scale.Depositional sequences stack in progradational, aggradational, retrogradational, or degradational patterns to form sequence sets—exactly analogous to the stacking patterns of parasequences within depositional sequences discussed in Bohacs et al. (2022a, Chapter 6 this Memoir). Successions of sequence sets accumulate between lower-order sequence boundaries to form lower-order composite sequences containing lowstand, transgressive, and highstand sequence sets.Each of the component, “higher order,” sequences has all the stratal attributes of a depositional sequence, including constituent parasequences and systems tracts, that play a dominant role in controlling the distribution of reservoir, source, and sealing mudstones. Nonetheless, the relative development (thickness and character) of systems tracts in higher-order sequences is strongly influenced by the lower-order stacking pattern of those sequences. Thus, lowstand systems tracts tend to be better developed in depositional sequences within lowstand sequence sets, transgressive systems tracts are better developed in transgressive sequence sets, and so forth in each respective portion of the composite sequence. These repeated stacking patterns of strata and surfaces enable prediction of lithofacies character and distribution, both away from sample control and below the resolution of typical seismic-reflection data. For example, the most widespread, fine-grained, and biogenically dominated strata in the proximate shelfal areas of a composite sequence tend to occur near the top of the transgressive sequence set.Large-scale sequence-set stratigraphic analysis indicates that mudstone reservoirs do not occur randomly but have a repeated and predictable distribution within one of four families—and that such analysis is essential for understanding the localized variations in reservoir potential and distribution. The shared attributes within each family provide objective criteria for selecting appropriate analogs among mudstone reservoir plays and highlight the utility of conducting a basin-to-play–scale stratigraphic analysis.
9 New Albany Shale, Illinois Basin, USA—Devonian Carbonaceous Mudstone Accumulation in an Epicratonic Sea: Stratigraphic Insights from Outcrop and Subsurface Data
Authors: Lazar O. R. , Schieber J. 
Published: March 2024

ABSTRACTExtensive organic-carbon–rich fine-grained rock successions accumulated in the epicontinental seas of Laurentia within sedimentary basins, including the Illinois, Appalachian, and Michigan Basins, during the Middle to Late Devonian. The New Albany Shale of the Illinois Basin illustrates the expression of sequence-stratigraphic surfaces and units in an epeiric, intracratonic sea. Four depositional sequences, bounded by laterally extensive erosion surfaces, are recognized and mapped within the Middle to Upper Devonian New Albany Shale succession. Depositional sequences and their component systems tracts have distinct physical, biogenic, and chemical signatures that translate into distinct source- and reservoir-rock properties. Mudstone units record the interplay of organic production, preservation, and dilution. Depositional sequences and systems tracts vary significantly in thickness vertically and laterally throughout the Illinois Basin. Spatial variation in thickness reflects differences in sediment supply and in accommodation resulting from the changes in paleotopography, sea level, and subsidence.This chapter illustrates that the sequence-stratigraphic approach provides fundamental insights even when the investigation is based on a fairly limited database consisting of a few cores, outcrops, and gamma-ray well logs acquired over several decades at various (and occasionally insufficient) resolutions. The resulting sequence-stratigraphic framework indicates that the sedimentary record of the New Albany Shale is quite discontinuous. Understanding the character and distribution of source- and reservoir-rock properties within this discontinuous stratigraphic succession is useful for focusing future, more detailed analyses of targeted intervals at different exploration to production phases.

ABSTRACTThe Upper Pleistocene to Holocene (post-last glacial maximum) succession of the Po River Plain, northern Italy, illustrates the expression of sequence-stratigraphic surfaces and stratal units in paralic and coastal-plain settings that are different from the settings of most of the mudstone units considered thus far in this book. This interval spans shallow-marine, shoreline, lagoonal, swamp, and fluvial-floodplain environments.The Po River Plain is an excellent place to study how the stratal record of changing eustasy is mediated by sediment-supply rates (detrital and biogenic) as well as by all the components of accommodation (e.g., subsidence, compaction, and groundwater table) for four reasons:Our study shows how applying the sequence-stratigraphic method and approach from first principles in transitional environments can provide insights into the accumulation of mud in a setting that is the critical link between continental hinterlands and marine depositional basins.
Miniaturized and highly sensitive fiber-optic Fabry–Perot sensor for mHz infrasound detection

Published: March 2024

Infrasound detection is important in natural disasters monitoring, military defense, underwater acoustic detection, and other domains. Fiber-optic Fabry–Perot (FP) acoustic sensors have the advantages of small structure size, long-distance detection, immunity to electromagnetic interference, and so on. The size of an FP sensor depends on the transducer diaphragm size and the back cavity volume. However, a small transducer diaphragm size means a low sensitivity. Moreover, a small back cavity volume will increase the low cut-off frequency of the sensor. Hence, it is difficult for fiber-optic FP infrasound sensors to simultaneously achieve miniaturization, high sensitivity, and extremely low detectable frequency. In this work, we proposed and demonstrated a miniaturized and highly sensitive fiber-optic FP sensor for mHz infrasound detection by exploiting a Cr-Ag-Au composite acoustic-optic transducer diaphragm and a MEMS technique-based spiral micro-flow hole. The use of the spiral micro-flow hole as the connecting hole greatly reduced the volume of the sensor and decreased the low-frequency limit, while the back cavity volume was not increased. Combined with the Cr-Ag-Au composite diaphragm, a detection sensitivity of −123.19 dB re 1 rad/μPa at 5 Hz and a minimum detectable pressure (MDP) of 1.2 mPa/Hz1/2 at 5 Hz were achieved. The low detectable frequency can reach 0.01 Hz and the flat response range was 0.01–2500 Hz with a sensitivity fluctuation of ±1.5 dB. Moreover, the size of the designed sensor was only 12  mm×Φ12.7  mm. These excellent characteristics make the sensor have great practical application prospects.
