Dinoflagellate cyst and pollen assemblages as tracers for marine productivity and river input in the northern Gulf of Mexico
Authors: Yedema Yord W. , Donders Timme , Peterse Francien , Sangiorgi Francesca 
Published: November 2023

Abstract. Both marine dinoflagellate cysts and terrestrially derived pollen and spores are abundant in coastal sediments close to river mouths, making sediment records from such settings ideal to simultaneously study land–ocean climate interactions, marine productivity patterns and freshwater input over time. However, few studies consider the combined calibration of these palynological proxies in modern coastal sediments offshore from rivers, which is needed to strengthen the interpretation of paleoreconstructions. Here, we analyze the palynological content of marine surface sediments along land–sea transects off the Mississippi and Atchafalaya river mouths in the northern Gulf of Mexico (GoM) and test three palynological indices which are often employed in the paleo-domain: (i) the abundance of cysts of heterotrophic and autotrophic dinoflagellates (dinocysts) as a tracer for primary productivity (H/A ratio) and (ii) the ratio between non-bisaccate pollen and bisaccates (P/B) as well as (iii) the ratio between pollen (excluding bisaccates) and dinocysts (P/D), which are both tracers for river input and distance to the coast. Our results show that dinoflagellate cysts are most abundant on the shelf, where heterotrophic dinocyst species dominate coastal assemblages in reach of the river plume, while autotrophic taxa are more present in the oligotrophic open ocean. This is clearly reflected in decreasing H/A values further offshore. Individual dinocyst taxa also seem to inhabit specific niches along an onshore–offshore transect, linked to nutrient availability and proximity to the turbid river plume. The highest pollen concentrations are found close to the Mississippi river mouth and mostly represent a mixture of local coastal and upstream vegetation, whereas bisaccate pollen was most abundant further offshore of the Mississippi river. Multivariate redundancy analysis (RDA) performed on both pollen and dinocyst assemblages, a set of environmental parameters, and the three palynological ratios showed that net primary productivity was the most important variable influencing the dinocyst assemblages, likely as the result of nutrient input. Additionally, the RDA confirmed that the H/A ratio indeed seems to track primary productivity, while the P/B ratio results in a robust indicator for distance to the coast, and the P/D ratio better reflects river input. Together, our data confirm and further specify the suitability of these three palynological ratios in river-dominated coastal margins as proxies for (past) marine productivity and distance to the coast and river.
Seawater carbonate chemistry considerations for ocean alkalinity enhancement research: theory, measurements, and calculations
Authors: Schulz Kai G. , Bach Lennart T. , Dickson Andrew G. 
Published: November 2023

Abstract. Ocean alkalinity enhancement (OAE) is a proposed marine carbon dioxide removal (mCDR) approach that has the potential for large-scale uptake of significant amounts of atmospheric carbon dioxide (CO2). Removing anthropogenic legacy CO2 will be required to stabilise global surface temperatures below the 1.5–2 ∘C Paris Agreement target of 2015. In this chapter we describe the impacts of various OAE feedstocks on seawater carbonate chemistry, as well as pitfalls that need to be avoided during sampling, storage, and measurement of the four main carbonate chemistry parameters, i.e. dissolved inorganic carbon (DIC), total alkalinity (TA), pH, and CO2 fugacity (fCO2). Finally, we also discuss considerations in regard to calculating carbonate chemistry speciation from two measured parameters. Key findings are that (1) theoretical CO2 uptake potential (global mean of 0.84 mol of CO2 per mole of TA added) based on carbonate chemistry calculations is probably secondary in determining the oceanic region in which OAE would be best; (2) carbonate chemistry sampling is recommended to involve gentle pressure filtration to remove calcium carbonate (CaCO3) that might have been precipitated upon TA increase as it would otherwise interfere with a number of analyses; (3) samples for DIC and TA can be stabilised to avoid the risk of secondary CaCO3 precipitation during sample storage; and (4) some OAE feedstocks require additional adjustments to carbonate chemistry speciation calculations using available programs and routines, for instance if seawater magnesium or calcium concentrations are modified.

Abstract. In February 2023, the sea-ice extent around Antarctica dropped to 1.79×106 km2, setting a satellite-era record low for the second straight year. Recent records stress the need for further research into the factors behind record-breaking Antarctic sea-ice anomalies. By influencing the circumpolar westerly winds, the stratospheric polar vortex has played a major role in the Antarctic surface climate in recent decades. However, the footprint of the polar vortex variability in the year-to-year changes in the Antarctic sea-ice cover remains obscured. Here, we use satellite retrievals and reanalysis data to study the response of the sea-ice extent around Antarctica to changes in the polar vortex strength. We focus on the last 2 decades that saw sharp changes in the stratospheric zonal flow, the tropospheric westerly winds and the sea-ice cover (the latter climbed to record highs in 2013 and 2014 before dropping to record lows in 2017, 2022 and 2023). Our results suggest that this unprecedented interannual variability is noticeably influenced by the polar vortex dynamics. The signature of the stratosphere–troposphere coupling is apparent in recent records (highs and lows) in the sea-ice extent around Antarctica.

Metakognitiv terapi

Published: November 2023

Metacognitive therapy (MCT) was developed by Adrian Wells and is founded on the self-regulatory executive function (S-REF) model, often referred to as the metacognitive model of psychological disorder. The metacognitive model assumes that symptoms of psychological disorder will naturally subside through a process of reflexive self-regulation. However, this process can be blocked by a cognitive attentional syndrome (CAS), consisting of worry, rumination, threat monitoring and maladaptive coping behaviours, and lead to prolonged emotional distress. The CAS is under the influence of a metacognitive control system, and biases in metacognitive knowledge held by this system are assumed to constitute the central mechanisms underlying the CAS and therefore psychological disorders in general. MCT was specially developed to achieve metacognitive change and enhance self-regulation using a set of transdiagnostic treatment techniques and procedures. In the current paper we present MCT, its conceptual foundation and central features. We briefly present some of the empirical evidence supporting the metacognitive model and therapy and how MCT can be applied to a case named Nadine.

Unified Protocol

Published: November 2023

Unified Protocol (UP) is a transdiagnostic treatment aimed at promoting emotion regulation skills in patients with emotional disorders. The approach targets maintaining factors common to many disorders, in line with recent knowledge about broad dimensions of personality underlying various diagnoses. It allows for the simultaneous treatment of comorbid disorders and can simplify training and treatment implementation. Central to emotional disorders is the individual’s negative reaction to their own emotions, and attempts to cope with them through avoidance or suppression. The goal of UP is to strengthen core skills that enable more adaptive ways of dealing with one’s emotions. These skills include understanding emotions, non-judgemental awareness, flexible thinking, the ability to do the opposite of avoidance behaviours, increased tolerance for physical sensations, and the ability to plan and carry out emotional exposure. In this article, we provide an overview of what a UP approach entails and illustrate this through the case of ‘Nadine’.

Published: November 2023

Aim: This study aims to retrospectively evaluate the fundamental motor competence of early adolescents and to examine the affecting factors. Methods: 89 children aged 11.33±0.95 were included in the study. Minnesota Manual Dexterity Test (MMDT) for manual dexterity, 9-Hole Peg Test (9-HPT) for finger dexterity, Korebalance™ Premiere for balance, manual muscle strength measurement device for quadriceps muscle strength, hand dynamometer for hand grip strength, EMG Biofeedback for muscle activation was used. Results: Compared by gender, there was a statistically significant difference in the right and left-hand placing of MMDT and 9-HPT (p=0.004, p=0.041, p=0.004, respectively). Comparison’s of age groups, there was a statistically significant difference in the left-hand placing and turning subtests of MMDT and left grip strength (p=0.010, p=0.048, p=0.025, respectively). In a correlation analyses, age had a correlation with the left-hand placing of MMDT (r=-0.336,p=0.001); and left grip strength (r=0.219,p=0.039). Height and weight had a correlation with dynamic balance (r=-0.242,p=0.022; r=-0.244,p=0.021). Weight and BMI had a correlation with static balance (r=0.342,p=0.001; r=0.305,p=0.004) and EMG Biofeedback score (r=0.237,p=0.025; r=0.212,p=0.046). Conclusion: Manual dexterity and hand grip strength develop with age in children, and girls' manual and finger dexterities are better than boys. While the increase in BMI and weight affect static balance negatively, the increase in height and weight affect dynamic balance positively. It is thought that investigating the factors affecting motor competence will be important in evaluating the development of children and directing them to appropriate sports.

Hesperidin Potentiates the Chemosensitivity of HT-29 Colon Cancer Cells to 5‐Fluorouracil
Authors: ARSLAN Aida , RCAN Burak , ERDEN Yavuz 
Published: November 2023

Aim:	Hesperidin is an important flavonoid compound of citrus fruits. It has the potential to be evaluated as a cytotoxic agent against a variety of malignant human cancer cells, especially in colon, pancreatic, breast, and other cancer types. The practical application of combination therapies is commonly used to eliminate or reduce drug resistance.
Materials and Methods:	In this study, hesperidin (0.001-300µM) and 5-fluorouracil (5-FU) (1-300 µM), a cytotoxic chemotherapy drug used for treating cancer, were applied both individually and in combination (100 µM) on the HT-29 cells (human colon cancer cell line). The effects of these compounds on HT-29 cell viability were revealed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide method, and the genotoxic effects on HT-29 cells were revealed using single-cell gel electrophoresis analysis.
Results:	The data obtained showed that the combination of 5-FU and hesperidin importantly decreased HT-29 cell viability compared to the group treated with 5-FU alone. These findings indicate that the combined application of these compounds is more effective than the individual administration of 5-FU or hesperidin alone.
Conclusion:	The research suggests that hesperidin might possess the ability to counter drug resistance in cancer cells, offering promising prospects when used alongside current anti-cancer medications. Nevertheless, to validate these findings, more extensive research and clinical trials are imperative.

У статті досліджено вплив сучасних процесів діджиталізації на зміну кредитної поведінки домогосподарств. Значна увага приділена визначенню сутності діджиталізації та з’ясуванню особливостей її впливу на ринок фінансових послуг. У статті також визначені та систематизовані базові ознаки, що притаманні як класичній моделі отримання кредитних послуг клієнтами фінансових установ, так і новій моделі кредитування, яка формується на сьогодні у результаті впливу процесів діджиталізації. Доведено, що значний вплив процеси діджиталізації здійснили і на функціонування ринку кредитних послуг, як одного з найбільш важливих ринків у функціонуванні всієї сфери фінансових послуг. Зауважено, що об’єктивні передумови існування такого ринку, призвели до того, що фінансові установи почали використовувати різні новітні технології для активного продажу кредитних продуктів, що у підсумку призвело до трансформації всього світового ринку кредитних послуг. Також результати дослідження засвідчили, що високий рівень конкуренції між фінансовими установами на окресленому ринку вимагає від фінансових установ постійно вдосконалювати власну діяльність, розробляти та впроваджувати все складніші технології, а їх застосування також поступово і змінює кредитну поведінку їх клієнтів, формуються нові вимоги до обслуговування, трансформуються базові принципи роботи усталеної моделі кредитування. Встановлено, що погляди та відношення клієнтів до кредитування поступово будуть змінюватися і у подальшому, а нові технології у цій сфері будуть лише поглиблювати ці процеси.

Published: November 2023

A apendicite é a causa mais comum de dor abdominal aguda que requer intervenção cirúrgica, com risco de desenvolvê-la ao longo da vida em torno de 7%. É uma das poucas condições cirúrgicas em que o diagnóstico pode ser suspeitado unicamente pela história e exame físico. Contudo, em alguns casos, sobretudo nos extremos de idade e em doentes debilitados, apresentações atípicas requerem o auxílio de métodos complementares. A clínica de obstrução intestinal pode estar presente na apendicite aguda, principalmente em casos atípicos. Dizemos que um quadro de obstrução intestinal encontra-se presente sempre que o conteúdo luminal do intestino é impedido de progredir distalmente de maneira habitual. A tríade clássica em um quadro de obstrução intestinal é composta por: parada de eliminação de gases e fezes, dor abdominal e distensão. As principais causas são bridas e aderências, hernias de parede abdominal e neoplasias. O tratamento depende da causa. Não há relato na literatura de apendicite aguda ocasionando formação de hérnia interna no intestino delgado e obstrução intestinal. A cirurgia foi decisiva para diagnóstico e tratamento do quadro de obstrução intestinal e apendicite aguda.
