Linking Models with Brain Measures
Authors: Love Bradley C.
Published: September 2020

Linking models and brain measures offers a number of advantages over standard analyses. Models that have been evaluated on previous datasets can provide theoretical constraints and assist in integrating findings across studies. Model-based analyses can be more sensitive and allow for evaluation of hypotheses that would not otherwise be addressable. For example, a cognitive model that is informed from several behavioural studies could be used to examine how multiple cognitive processes unfold across time in the brain. Models can be linked to brain measures in a number of ways. The information flow and constraints can be from model to brain, brain to model, or reciprocal. Likewise, the linkage from model and brain can be univariate or multivariate, as in studies that relate patterns of brain activity with model states. Models have multiple aspects that can be related to different facets of brain activity. This is well illustrated by deep learning models that have multiple layers or representations that can be aligned with different brain regions. Model-based approaches offer a lens on brain data that is complementary to popular multivariate decoding and representational similarity analysis approaches. Indeed, these approaches can realise greater theoretical significance when situated within a model-based approach.
Structural and interactional aspects of adverbial sentences in English mother-child interactions: an analysis of two dense corpora
Authors: De Ruiter Laura Edwina , Lieven Elena , Brandt Silke , Theakston Anna L. , Lemen Heather
Published: September 2020

We analysed both structural and functional aspects of sentences containing the four adverbials “after”, “before”, “because”, and “if” in two dense corpora of parent-child interactions from two British English-acquiring children (2;00 – 4;07). In comparing mothers’ and children’s usage we separate out the effects of frequency, cognitive complexity and pragmatics in explaining the course of acquisition of adverbial sentences. We also compare these usage patterns to stimuli used in a range of experimental studies and show how differences may account for some of the difficulties that children have shown in experiments. In addition, we report descriptive data on various aspects of adverbial sentences that have not yet been studied as a resource for future investigations.

Drinking water is considered one of the basic human needs that cannot be dispensed with for any reason and the water must have quality standards in terms of taste and color in addition to the physical, chemical and biological specifications. The bottled water industry has flourished in recent decades, and the demand for it has increased in most parts of the world and for various reasons, perhaps the most prominent of which is the quality of bottled water and the regularity of that quality in different seasons, while the water changes its quality due to the quality of the source ,in addition to the possibility of contamination during transportation or when it is poorly stored, which It leads to a change in some physical and chemical properties of water. On this basis, specific samples were selected for all companies that manufacture bottled water at Duhok Governorate area, and then all samples were examined, both chemical and physical, to obtain laboratory results for these samples.
The best laid plans: Computational principles of ACC
Authors: Holroyd Clay B. , Verguts Tom
Published: September 2020

Despite continual debate for the past thirty years about the function of anterior cingulate cortex (ACC), its key contribution to neurocognition remains unknown. However, recent computational modelling work has provided insight into this question. Here we review computational models that illustrate three core principles of ACC function, related to hierarchy, world models and cost. We also discuss four constraints on the neural implementation of these principles, related to modularity, binding, encoding and learning and regulation. These observations suggest a role for ACC in hierarchical model-based hierarchical reinforcement learning, which instantiates a mechanism for motivating the execution of high-level plans.
Experiments in political psychology
Authors: Fischer Kyle , Atkinson Quentin , Chaudhuri Ananish
Published: September 2020

This chapter provides an overview of studies that use incentivised experiments to study political ideology. We look first at studies that conceptualise political ideology along a unidimensional liberal-conservative spectrum and explore whether there are behavioural differences between liberals and conservatives. While recent studies find that liberals display more pro-sociality, many other studies find that liberals and conservatives display similar levels of pro-social, ingroup-biased, normative, and punitive behaviour. We then turn to experiments that study two-dimensional political ideology as embodied in the concepts of economic conservatism/progressivism (often measured with the Social Dominance Orientation scale) and social conservatism/progressivism (usually measured with the Right-Wing Authoritarianism scale). In such experiments, economic conservatives display lower levels of pro-sociality and universalism and greater tolerance of inequality and tendencies to harm outgroups. Social conservatives tend to display “groupishness”, including distrusting anonymous strangers, cooperating with ingroup members, following rules, punishing in the ultimatum game, and sometimes harming outgroups.
Pet Attachment and the Interpersonal Theory of Suicide
Authors: Douglas Valerie Jane , Kwan Mun Yee , Gordon Kathryn H.
Published: September 2020

https://doi.org/10.1027/0227-5910/a000822 Background: Pet ownership is often assumed to have mental health benefits, but the effect of pets on suicide risk has a scant literature. Aims: Using the interpersonal theory of suicide, we examined the relationships between perceived burdensomeness (PB), thwarted belongingness (TB), overall attachment to one’s pet, pet attachment avoidance or anxiety, and suicide risk. Three hypotheses were investigated: 1) higher attachment would be indirectly associated with lower suicide risk via lower TB and lower PB, 2) attachment would be associated with higher suicide risk, as conditioned on attachment avoidance/anxiety, and 3) attachment avoidance/anxiety would be associated with higher suicide risk via higher TB/PB. Method: Undergraduates (N=187) completed surveys and indirect effect and conditional effect analyses were utilized. Results: Overall attachment was associated with lower PB, which was associated with lower suicide risk. The relationship between overall attachment and suicide risk was not conditional upon attachment anxiety/avoidance. Attachment avoidance was associated with increased levels of TB, which was associated with increased suicide risk. Attachment anxiety was associated with increased suicide risk via TB and PB. Limitations: We used a university sample that had limited access to pets. Conclusions: Findings suggest that pet ownership may provide mixed associations with suicide risk.

Published: September 2020

Background: Health behaviors such as physical activity and a balanced diet are essential to promote and maintain health. Especially during a crisis, such as the COVID-19 pandemic, they have the potential to buffer against stress and protect mental health. Method: In a longitudinal study with four measurement points over 3 months during the COVID-19 pandemic, about 3,500 randomly selected participants representative of the German population reported their mental health (i.e., anxiety, depression, loneliness), screen time, snack consumption, and physical activity. Results: Symptoms of anxiety, depression, and loneliness were highest during the first month of the pandemic-related lockdown, particularly in women and people in poor health, and decreased over time. Screen time and snacking increased and physical activity decreased compared to pre-lockdown. Snacking and physical activity went back to pre-lockdown levels within 2 months; screen time increased further over time. Snack increase and physical activity decrease was stronger in women than men throughout the lockdown. Generally, more screen time, more snacking, and less physical activity were related to higher symptoms of anxiety, depression, and loneliness across all time points. Changes in health behaviors over time did not predict changes in mental health symptoms. Conclusions: Mental health and health behaviors worsened as an immediate response to stress but mostly returned to pre-crisis levels within 2 to 3 months. Engaging in healthier behaviors is associated with better mental health. This study provides important descriptions of (unintended) side effects of a national crisis and contributes to our understanding of how to preserve mental health.
Gender, motherhood, and the perception of just earnings: Results of a multifactorial (vignette) study
Authors: Wysienska-Di Carlo Kinga , Karpiński Zbigniew
Published: September 2020

Gender pay gaps and wage penalties for mothers are well-established phenomena. Their persistence may be partially explained by the fact that the unequal distribution of rewards between genders is often perceived as just and legitimate. The goal of our study was to establish to what extent and under what conditions motherhood and fatherhood status affect perceptions of just inequalities. Using expectation states theories, we predicted that there would be greater acceptance of the unequal distribution of rewards between women and men with the same job experience in top-level occupations compared with bottom and mid level occupations. We also predicted that being a male or female parent would further accentuate the relationship between gender and occupational prestige, leading to acceptance of even greater income gaps between mothers and fathers. A vignette study conducted in 2017 on a representative sample of Polish respondents active in the labor force, which yielded approximately 38,000 observations, provides evidence partially conforming to our predictions. That is, willingness to tolerate differences in just earnings for men and women is higher in the high occupational status categories than in the medium and low occupational status categories. The effects of parenthood are less clear. Although the legitimized difference in earnings varies by age and parenthood status, we found rather moderate levels of motherhood penalties and much higher premiums for fatherhood, especially at the early stages of men’s careers. In addition, contrary to our predictions, mothers in high-prestige occupations were not penalized more than mothers in low and medium prestige occupations. Perceptions of legitimized inequalities between genders were independent of respondents’ characteristics.

Justice evaluations and just earnings: Analysis of a pilot survey
Authors: Karpiński Zbigniew , Wysienska-Di Carlo Kinga
Published: September 2020

In this note, we present the procedure used to transform subjective evaluations of the justice of earnings provided by participants in a vignette survey to just earnings — that is, earnings that the participants think would be just for persons described in the vignettes. To perform that transformation, we use a mixed-effect model with random effects associated with vignettes and respondents. The functional form of the model is determined by theoretical considerations — i.e., postulates of Jasso’s comparison theory. The note includes R code that can be used to replicate the analysis and reproduce its results.
Re-examining female labor supply responses to the 1994 Australian pension reform
Authors: Morris Todd
Published: September 2020

Many governments are aiming to extend working lives by raising the age at which people can claim retirement pensions. This makes it vital to understand how these policies affect retirement decisions. In this paper, I revisit the labor supply effects of a major Australian reform that increased women’s pension age from 60 to 65. Atalay and Barrett (2015) studied these effects using repeated household surveys and a differences-in-differences design in which male cohorts form the comparison group. They estimate that the reform increased female labor force participation by 12 percentage points. Using earlier data, I show that the parallel-trends assumption did not hold before the reform because of a strong female-speciﬁc trend in participation rates across the relevant cohorts. Accounting for this trend, the estimated effect on female participation falls by two-thirds and becomes statistically insigniﬁcant at conventional levels. This highlights the importance of carefully assessing and controlling for trends across cohorts when evaluating pension reforms, which are typically phased in across cohorts.

Authors: Коvtun Al’bina
Published: September 2020

The article is devoted to the study of the specifics of the formation of religious meanings with the help of the intraword hyponymic (genus-species) relations. It was revealed t hat in semantic structures of lexemes, this type of semantic derivation is capable of actively deploying stable specialized religious(specific, hyponymic) meanings from commonly used (generic, hypernymic) ones. It was also found that in times of Christianization, the fixation of hyponyms often led to the disappearance of hypernyms. The process of transferring religious hyponyms without hypernyms from other languages into the Old Kyiv language was quite active. Forming a paradigm through hyponymic relations reflects a variety of changes in the represented reality associated with the linguistically conservative religious sphere of Ukrainians: the names remained unchanged, while language objects, acquiring new functions, changed, and the speakers’ knowledge of the objects deepened.
Mizh eksperymentom ta intelektualʹnym pysʹmom: hra z literaturnoyu tradytsiyeyu u romani Mayka Yohansena „Podorozh uchenoho doktora Leonardo i yoho maybutnʹoyi kokhanky prekrasnoyi Alʹchesty u Slobozhansʹku Shvaytsariyu”
Authors: Hirnyak Mar‘yana
Published: September 2020

The article deals with the novel The Travel of Scientist Dr. Leonardo […] by Mike Johansen which manifests the author’s predisposition to experimental game with literary tradition and classic poetics as well as to the intellectual writing. The experiment can be observed foremost in the decentration of the novel’s structure and textual communicative strategies. The author creates “the book of Landscape” as opposed to the narrative about events and characters. He plays with the reader, emphasizing on his presence permanently and exposing artistic techniques, uses language code switching and inserted constructions, creating an effect of cinematography. The intellectualization of writing is proved by intertextual links (first of all, parodying different literary styles), presence of irony as worldview principle in the work, motivation for the reader to construct possible worlds and to oscillate at the limit of the factuality and fictionality as well as by reflections devoted to the philosophy of things, landscapes, travels and laws of being.
Early stage crack detection in mechanically joined steel/aluminum joints by condition monitoring
Authors: Gollnick Maik , Giese P. , Hein D. , Meschut G. , Herfert D.
Published: September 2020

Monitoring systems for machines, plants, materials and equipment are increasingly used in production processes. These online condition monitoring systems can detect damage or excessive loads at an early stage and can drastically reduce or prevent long downtimes of plants and machines as well as high repair and maintenance costs. This paper depicts a method for online crack detection with pattern recognition methods for specimens joined by self-pierce riveting under cyclic load in fatigue tests (laboratory application). A software specially conceived for this application was developed. This software, AnrissMF, uses active acoustic testing with a structure-borne sensor to detect cracks in the joints at a very early stage. It is shown in this paper that this software can detect cracks much earlier than classical failure criteria for joints (i. e. before any drop in stiffness or frequency is observed). Furthermore, the successful application of software AnrissMF for online crack detection during the fatigue strength test is presented.
Microstructure, mechanical and corrosion properties of TIG welded Hastelloy C-276
Authors: Tümer Mustafa
Published: September 2020

Hastelloy C-276 is a corrosion resistant nickel based solid solution hardened industrial alloy which has superior mechanical and corrosion properties. In this study, Hastelloy C-276 alloy was welded via the GTAW (Gas tungsten arc welding) method using ERNiCrMo-4 filler metal. Tensile, bending and notch impact tests were performed to determine the mechanical properties. The microstructure of the weld metal was investigated by light microscopy (LM), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The impact toughness values of the heat affected zone (HAZ) showed a better performance than those of the weld metal. In addition, the corrosion properties of the weld metal and the base material were investigated by potentiodynamic polarization tests. Electrochemical potentiodynamic polarization parameters were determined according to corrosion behavior and microstructure properties. In particular, the corrosion rate of the weld metal increased because of the Mo-rich phases deposited in the weld metal microstructure.
Residual stress evaluation during RSW of DP600 sheet steel
Authors: Elitas Muhammed , Demir Bilge
Published: September 2020

In this study, resistance spot welding (RSW) process has been used on DP600 automotive steel at pressures of 2, 3, 4, 5 and 6 bar at a welding current of 7 kA. Microstructure, hardness and residual stress were examined to evaluate the effect of the welding pressure. An experiment at 5 kA and 6 bar was also conducted to investigate the effect of welding current on this behavior of steel sheet. The results show that microhardness values were higher in the welding region than in any other parts. There was no considerable change in the hardness behavior versus the welding pressure applied except for the sample welded at 7 kA and 4 bar. When the welding current changed from 7 to 5 kA, hardness improved. Residual stress evaluation reveals that compression stress was found in the specimens, and the specimen welded at 5 kA and 6 bar exhibited the highest residual stress.
Characterization of hydrogen in a high strength aluminum alloy
Authors: Yang Xiao , Luo Xianfu , Zhang Xianfeng , Chen Jieming , Gao Lingqing
Published: September 2020

High strength aluminum alloys have a face-centered cubic structure and it is not easy to form hydrides due to the extremely low solubility of hydrogen. Therefore, it is very difficult to test and characterize hydrogen in the high-strength aluminum alloys. In this work, the penetration of hydrogen and the distribution of hydrogen near the crack tip in the highstrength aluminum alloy were analyzed by time of flight secondary ion mass spectrometry (TOF-SIMS). Meanwhile, the test method of trace H in highstrength aluminum alloy was investigated by using TOF-SIMS technology.
The effect of bellydance fitness on the functionality of the torso muscles of women of the first period of adulthood
Authors: Chervonoshapka M. , Shutka H. , Hnyp I.
Published: September 2020

The first period of mature age (21-35 years) of women is characterized by the beginning of involutionary processes in the body and a decrease in the motor abilities of women, and the solution to this problem is possible by optimizing their motor activity. An important factor in training for mature women is to ensure a positive effect on the functional state of the muscles of the torso. Classes in dance types of health-improving motor activity (in particular, bellydance- fitness) have a positive effect on the psycho-emotional state of women and the state of their musculoskeletal system. The work is devoted to the research of the influence of the practice of bellydance-fitness (fitness with movements of oriental dance) on the functional state of the trunk muscles of women of the first period of mature age. Indicators of physical qualities such as static and dynamic strength endurance of torso muscles; spinal mobility in women engaged in bellydance-fitness were studied. Indicators of physical preparedness of women with less than 4 months of training and women with 2-3 years of training were compared. It was a positive effect of bellydance-fitness on the level of functional state of the torso muscles of women. Women with 2-3 years of training are characterized by a higher level of strength of the muscles of the torso and mobility of the spine than women with less than 4 months of training. The results of the research give grounds to recommend the use of bellydance-fitness as a means of improving the functional state of the torso muscles of women.

Published: September 2020

The article is dedicated to the trickster problematics. The methods of investigation: sociocultural analysis, comparative and biographical methods, interpretation. The subject of investigation: a trickster of modern Ukrainian sociocultural reality on the example of Verka Serdjuchka, the modern Ukrainian pop star (Andriy Danylko, the artist). The results of investigation: based on the works of famous foreign and Ukrainian scientists dedicated to mythologem problematics and trickster archetype and using generalizing characteristics of this cultural phenomenon identified by Mark Lipovetsky, Professor of Colorado University (the USA) (such as ambivalence, mediator function, liminality, transformation of transgression into artistic gesture, direct or indirect connection with sacral context) the character of Verka Serdjuchka as a trickster was analyzed. The work emphasizes such special characteristics of this cultural hero as aptitude to transformation (external and inner, social and cultural), status changes ( from a saleswoman and a train host to a glamorous show programme host and a first-rate pop star, the fact being confirmed by the second place won at the Eurovision song contest in 2007 ); changes in the appearance (from a frayed jacket, a checked skirt and a beret to a futuristic silver garment with a metal star on the head); changes in speech and lyrics of the songs, that is, substantial decrease in the use of surzhyk ( a mixture of Russian and Ukrainian words); manifestation of Ukrainian identity which wasn't expressed before.

Authors: Mostajeran Zeinab , Mosavat Seyed Hamdollah , Najafi Mostafa , Emtiazy Majid , Hashempur Mohammad Hashem
Published: September 2020

Background: Attention deficit hyperactivity disorder (ADHD) is a common, chronic, neurodevelopmental disorder that manifests in childhood with symptoms of hyperactivity, inattention, and impulsivity. Ma’aljobon (a kind of whey protein) that is derived from milk during cheese producing process is a popular dietary traditional product supposed to provide immune modulation and prevent neuropsychiatric disorder. We aimed to evaluate the efficacy of ma’aljobon in management of Attention-deficit/hyperactivity disorder (ADHD). Materials and Methods: In this open-label randomized, double arm, and controlled clinical trial, sixty four patients with ADHD who referred to out-patient child and adolescent clinic of Khorshid Hospital of Isfahan, Iran, were randomly assigned in the intervention group (ma’aljobon 25 g once daily plus standard conventional treatment (SCT)) or control group (SCT only) for a period of 8 weeks. Scores of the Strengths and Difficulties Questionnaire (SDQ) and Conners’ Continuous Performance Test (CPT) were set as the outcome measures. Results: Parent reported hyperactivity scale of SDQ showed a significant decrease in the intervention group compared to the control group (P=0.04). However, no significant between groups differences were observed in other scales of parent-reported SDQ. Also, according to the results of CPT, there was a significant improvement in the intervention group regarding attention and focus score (P=0.01). Conclusion: Ma’aljobon might be considered as a complementary remedy for improving hyperactivity, attention and focus of children with ADHD. However, further researches with larger sample size and longer duration should be done for achieving more reliable results. [GMJ.2020;9:e1690]
Determination of the Excitatory Effects of MicroRNA-30 in the Self-Renewal and Differentiation Process of Neonatal Mouse Spermatogonial Stem Cells
Authors: Khanehzad Maryam , Abolhasani Farid , Hassanzadeh Gholamreza , Nourashrafeddin Seyed Mehdi , Hedayatpour Azim
Published: September 2020

Background: Spermatogonial stem cells (SSCs) are considered as special stem cells since they have the ability of self-renewal, differentiation, and transferring genetic information to the next generation. Also, they considered as vital players in initiating and preserving spermatogenesis. The fate decisions of SSCs are mediated by intrinsic and extrinsic factors, among which microRNAs (miRNAs) are one of the most essential factors in spermatogenesis among endogenous regulators. However, the mechanisms by which individual miRNAs regulate self-renewal and differentiation of SSCs are unclear. The present study aimed to evaluate the impact of miRNA-30 mimic on fate determinations of SSCs. Materials and Methods: The obtained SSCs from neonatal mice (3-6 days old) were purified by MACS and flow cytometry with a promyelocytic leukemia zinc-finger marker. Then, the cultured cells were transfected with miRNA- 30 mimic, and finally, the changes in expressing ID4 and c-kit proteins were assessed by western blot analysis. Results: According to flow cytometry findings, the percentage of SSC purity was about 98.32. The expression of ID4 protein and colonization increased significantly through the transfection of miRNA-30 mimic (P<0.05). Conclusion: The miRNA-30 controls spermatogonial stem cell self-renewal and differentiation, which may have significant implications for treating male infertility. [GMJ.2020;9:e1829]

Published: September 2020

La falta de acceso a fuentes de agua segura es un problema en el Caribe Mexicano, particularmente en comunidades con irregularidad en servicios. Ante esto, la captación de agua de lluvia (CALL) podría representar una alternativa para satisfacer necesidades básicas. Sin embargo, los esquemas de implementación a menudo son verticales y jerárquicos. En este trabajo se aportó conocimiento sobre las percepciones y formas de uso del agua de lluvia, para contribuir a la toma decisiones. La información se obtuvo mediante observaciones etnográficas y encuestas a 60 representantes de hogar de una muestra de 253 viviendas en la comunidad de Puerto Morelos, Quintana Roo. El 95 % de los encuestados fueron foráneos, por lo que sus percepciones y formas de manejo del recurso fueron heterogéneas: desde sistemas simples (cubetas y tambos) hasta sistemas complejos integrados a las viviendas. En general, la CALL cuenta con una percepción positiva por parte de la población estudiada, lo cual permitiría su implementación en proyectos más estructurados que promuevan el mejoramiento de las técnicas de captación en la localidad.

The issue of plagiarism is one of the issues that gets great attention among the academic world and is our common concern. As a manufacturer of science, Higher Education has a big responsibility to provide education and socialization related to the prevention of plagiarism. The initial conditions of our partners (students of the Islamic Economics Study Program, Faculty of Islamic Studies, Kalimantan Islamic University, Syeh Muhammad Arsyad Al-Banjari), are having difficulties in avoiding the culture of copy-paste in completing their academic assignments, especially in doing thesis.

Most students still do not understand the term plagiarism and how to avoid it. After going through community service activities under the title "Training of Paraphrasing Techniques for Writing Student Thesis as an Effort to Avoid Plagiarism" which we carried out on September 22, 2018 then our partners can apply good paraphrasing techniques to avoid plagiarism.

The research and community service program in the Pusat Penelitian dan Pengabdian Kepada Masyarakat (P3M) Politeknik Negeri Banjarmasin (Poliban) was prepared with reference to the application of science and technology that is able to provide appropriate solutions to problems, needs, and challenges in society. While community service activities focus on supporting efforts to improve community welfare and the competitiveness of universities.

Based on the 2016-2021 RPJMD vision, the South Kalimantan province's medium-term regional development mission is set for 2016-2021, one of which reads "Developing regional infrastructure that supports the acceleration of economic and social cultural development". Based on the mission, the province of South Kalimantan must provide a solution to the issue of uneven infrastructure development problems. One of the solutions that can be implemented relates to the availability of clean water in rural areas with the program "Infrastructure Development to Meet the Health of the Clean Water of Rural Communities". The problems that arise in the implementation of the program are limited equipment, technology and science, therefore Poliban in this case the P3M tries to provide a solution to the problems that exist in the village of Karyabaru, Barambai sub-district, Barito Kuala District which is very short of clean water. The solution is to make a solar water pump in the village of Karyabaru, Barambai sub-district, Barito Kuala Regency. The community service programs were carried out in partnership with the Karyabaru and Karang Taruna Village Devices / Karyabaru Village Farmers Group.

In order to guarantee the sustainability of the program that has been implemented later, it is then carried out assistance to the community so that all members of the community can participate in maintaining, caring for and implementing standards in the management of solar water pumps to meet clean water needs.

Association Between Serum Magnesium Levels and Alzheimer’s Disease or Mixed Dementia Patients: A Population-Based Retrospective Controlled Study
Authors: Ben Zaken Sara , Radomysky Zorian , Koren Gideon
Published: September 2020

Background:

High magnesium intake has been associated with a decreased risk of dementia. In contrast, other research has found that both low and high serum magnesium levels were associated with an increased risk of Alzheimer’s disease and mixed dementia. Hence, presently the role of magnesium levels in dementia is unclear.

Objective:

To investigate a possible association between serum magnesium concentrations and dementia in a large population-based sample.

Methods:

Maccabi Healthcare Service in Israel provides healthcare to over 2 million citizens. Maccabi maintains a registry with approximately 26,000 diagnosed dementia patients. We focused on patients of both sexes with Alzheimer’s disease or mixed dementia aged 65 or older, excluding patients with clinical diagnoses that could affect serum magnesium level, or with other causes of cognitive decline. Our control group consisted of patients of the same age and sex without dementia.

Results:

No significant differences were found in mean, mode, and median magnesium levels between the dementia and control groups. However, there were marginally but significantly more cases with low magnesium levels among dementia patients than among controls: A total of 9.4% of tests done in patients with dementia and 7.81% done in non-dementia subjects were hypomagnesemic ( p <  0.00001).

Conclusion:

Despite similar means and medians of serum magnesium in dementia and controls, the proportion of lower than normal magnesium test results was slightly higher among dementia patients. It is possible that patients with dementia have more episodes of hypomagnesemia than controls, despite similar overall mean levels of magnesium.

INTRODUCTION: The volatile endogenous mediator hydrogen sulfide (H2S) is known to impair thrombus formation by affecting the activity of human platelets. Beside platelets and coagulation factors the endothelium is crucial during thrombogenesis. OBJECTIVE: This study evaluates the effect of the H2S donor GYY4137 (GYY) on human umbilical vein endothelial cells (HUVECs) in vitro. METHODS: Flow cytometry of resting, stimulated or GYY-treated and subsequently stimulated HUVECs was performed to analyse the expression of E-selectin, ICAM-1 and VCAM-1. To study a potential reversibility of the GYY action, E-selectin expression was further assessed on HUVECs that were stimulated 24 h after GYY exposure. A WST-1 assay was performed to study toxic effects of the H2S donor. By using the biotin switch assay, protein S-sulfhydration of GYY-exposed HUVECs was assessed. Further on, the effects of GYY on HUVEC migration and von Willebrand factor (vWF) secretion were assessed. RESULTS: GYY treatment significantly reduced the expression of E-selectin and ICAM-1 but not of VCAM-1. When HUVECs were stimulated 24 h after GYY treatment, E-selectin expression was no longer affected. The WST-1 assay revealed no effects of GYY on endothelial cell viability. Furthermore, GYY impaired endothelial migration, reduced vWF secretion and increased protein S-sulfhydration. CONCLUSIONS: Summarizing, GYY dose dependently and reversibly reduces the activity of endothelial cells.

OBJECTIVE: To investigate the diagnostic accuracy of high-resolution ultrasound (HRU) for the detection of hepatic metastases of breast cancer in a humanized tumour mouse (HTM) using clinical standard technology. In addition, the efficiency of standard contrast-enhanced ultrasound (CEUS) [microbubbles of sulphur hexafluoride] and CEUS using a novel VEGFR2-targeted contrast agent [BR55®] was examined. METHODS: A total of 14 HTM were sonographically examined twice. In addition to a human immune system, the animals developed hepatic tumour lesions after intrahepatic injection of BT-474 breast cancer cells. Digital cine loops from the arterial phase (15–35 sec), the portal venous phase (35–90 sec) and the late phase (3–15 min) of the entire liver were analysed. Data were correlated to histopathology. RESULTS: After 9 months, half of the mice (7/14) revealed the development of hepatic breast cancer metastases. The detection limit was 1 mm tumour diameter. In particular, the use of targeted contrast media reduced the needed tumour diameter and helped to precisely classify tumour tissue. In 93% (13/14), the findings of ultrasound could be approved by histological examination by the pathologist. CONCLUSIONS: This study in HTM demonstrated the high feasibility of tumour specific contrast media and standard HRU contrast agents to detect early liver metastases.

BACKGROUND: Transient receptor potential channel 7 (TRPM7) plays an important role in maintaining intracellular ion concentration and osmotic pressure. OBJECTIVE: The purpose of this study was to investigate the role and mechanism of inhibiting the expression of TRPM7 in the treatment of distal myocardial ischemia. METHODS: H9C2 cells were treated with hypoxia post-treatment and reperfusion, respectively, detect the expression of HIF-1α and TRPM7, the concentration of Ca2+ and the degree of apoptosis in the H9C2 cells. The relevant miRNAs targeting TRPM7 were searched, the TRPM7 interference vectors were constructed, and the interference of different interference vectors on TRPM7 in H9C2 cells was detected. RESULTS: The results showed that hypoxia post-treatment treatment would lead to increased expression of miR-22-3p which directly targeting TRPM7, decreased expression of TRPM7, increased expression of HIF-α and increased intracellular Ca2+ concentration. While reperfusion can increase the expression of HIF-1α and TRPM7 in H9C2 cells and increase the degree of apoptosis. CONCLUSION: Knockdown of TRPM7 can significantly reduce reperfusion injury in H9C2 cells, reduce the degree of apoptosis, and the TRPM7 interference vector can inhibit the expression of TRPM7 and have a certain protective effect on the reperfusion injury of H9C2 cells.
