La situación jurisprudencial de las técnicas de reproducción humana asistida en los tribunales peruanos
Authors: Varsi-Rospigliosi Enrique , Valdivia Fierro Twany Fiorella 
Published: February 2025

La situación peruana en materia de Técnicas de Reproducción Humana Asistida – TERAS, ha tenido un notable incremento desde las últimas décadas debido al surgimiento de diversos factores de índole patológico y/o social que ha generado que las personas recurran a estos nuevos métodos debido al padecimiento de lo que la Organización Mundial de la Salud cataloga como una enfermedad: la infertilidad. En ese sentido, se evidencia que las TERAS vienen cobrando especial preponderancia en el ámbito nacional; sin embargo, al no encontrarse reguladas de forma expresa en la normativa peruana, se han generado una serie de problemas legales en el reconocimiento del vínculo filial de los nacidos por este procedimiento respecto de quienes tuvieron la “voluntad procreacional” de concebirlos. Estos problemas han suscitado diversa jurisprudencia que en su mayoría ha recaído en la determinación de una maternidad o paternidad alternativa. Es así que el presente artículo tiene como objeto presentar y analizar los distintos casos discutidos en la Corte Suprema y en el Tribunal Constitucional del Perú en materia de TERAS, siendo la “ovodonación” y la “gestación subrogada” las que han logrado diversos pronunciamientos judiciales que vienen planteando una interesante línea jurisprudencial sustentada en principios generales del Derecho.

Abstract
We recruited caregivers of individuals ages 0–21 with Down syndrome (DS) to complete an electronic survey. Multiple recruitment sources and methods were used. From 2023–2024, we received 542 valid, complete survey responses. We found the most success with use of DS affiliate organizations, the DS-Connect® contact registry for DS, and outreach to DS clinic patients. Of those who started the screener, 1,569 people screened in and were eligible; of those eligible, 730 (46.5%) consented. We experienced bots and fraudsters despite efforts to minimize those respondents from the outset. We present lessons learned in surveying caregivers from a low-incidence medical condition, with focus on our experience with invalid respondents, to inform other researchers conducting survey research related to genetic syndromes.

Background
Typhoid fever causes substantial mortality and morbidity in low and middle-income countries (LMICs) as a result of inadequate water, hygiene, and sanitation facilities. The gold standard for typhoid diagnosis is blood culture, however this method is expensive and mostly unavailable in LMICs. Environmental surveillance (ES) could offer a low cost alternative to identify circulation of Salmonella enterica serovar Typhi (S.Typhi) and help inform public health interventions including vaccination.

Methods
We implemented standardized protocols for ES at 40 validated sites in peri-urban communities in Ghana from July 2022 to August 2023. Grab samples (GS) and Moore swabs (MS) were collected monthly for the initial 6 months and subsequently monthly MS were maintained for the rest of the study period. Wastewater samples were tested for S. Typhi target genes (ttr, staG, tviB) and a biomarker of human faecal contamination (Bacteroides HF183) using multiplex quantitative PCR (qPCR). Clinical surveillance for typhoid fever was performed by blood culture of febrile cases presenting to the local hospital who lived in the study area.

Results
For the first 6 months of wastewater ES, we observed a higher prevalence of S. Typhi in MS compared to GS [100/240 (42%; 95% Confidence Interval [CI]: 34-50% vs. 24/240 (10%; 95% CI: 6-16%)]; p-value < 0.001]. Overall, the detection of S. Typhi throughout the study period based on MS was 42.1% (202/480; 95% CI: 35-50%). The prevalence of S. Typhi in blood culture surveillance was 0.21% [12/5,576; 95% CI: 0.12-0.38%]. Precipitation (1.1 (95% CI: 1.02-1.10) and number of wet days (2.0 (95%CI: 1.40-2.88) were positively associated with an increased odds of S. Typhi detection in MS and GS.

Conclusion
Generally the proportion of S.Typhi detections in wastewater samples was less than blood culture-based detections. Limited detection of confirmed typhoid fever cases at the local hospital may reflect healthcare seeking behaviours, access as well as early treatment with over-the-counter antibiotics. Further work is required to confirm these qPCR detections with amplicon sequencing methods. Strategies also needs to be developed for integration of ES into public health decision making for the prevention of typhoid fever.
Coordination and variability of muscular activation in male athletes with and without subacromial impingement syndrome: A case-control study
Authors: Sheikhhoseini Rahman , Abdollahi Sajjad , Salsali Mohammad , Anbarian Mehrdad , Guess Trent M. 
Published: February 2025

Objectives
Athletes with Subacromial Impingement Syndrome (SIS) exhibit altered muscular coordination and variability during repetitive shoulder movements compared to athletes without SIS. This research compared the Coordination and Variability of Muscular Activation in Male Athletes with and Without SIS.

Methods
In this case-control study, twenty-four male athletes were recruited and divided into two groups: those with SIS (n = 12) and those without SIS (n = 12). Participants performed a repetitive reaching task (RRT) for a minimum of fifteen repetitions. Electromyography (EMG) data were recorded from selected shoulder muscles. Muscle synergies, intra-group variability, and inter-group variability were extracted from the EMG data. An independent sample t-test or Mann-Whitney U-test was employed to analyze data at a significance level of 95% (α < 0.05).

Results
Three observable muscle synergy patterns were identified in both groups. Significant differences in variance accounted for (VAFmuscle) were found in the posterior deltoid, subscapular, and middle deltoid muscles, but these differences may not be clinically significant and warrant further research. No significant statistical differences were found in intra-group variability between the groups, which may suggest that the hypothesis is not fully supported. However, significant differences in inter-group variability were observed between the SIS and control (CON) groups.

Conclusions
This study showed differences in muscular coordination and variability during RRT in athletes with and without SIS. Three different muscle synergy patterns were demonstrated in both groups. It seems that timing and coordination changes in muscle activation may influence movement efficiency and increase the risk of performance errors.

Abstract
The increasing environmental concerns over wastewater contamination have spurred significant interest in developing efficient and sustainable methods for wastewater treatment. In this study, a simple and user-friendly approach was employed to synthesize iron oxide nanoparticles (IO-NPs) using Musa acuminata peel extract as a reducing and stabilizing agent. The synthesized IO-NPs were thoroughly characterized using transmission electron microscopy, X-ray diffraction, scanning electron microscopy, Fourier-transform infrared spectroscopy, ultraviolet–visible spectroscopy, energy-dispersive X-ray spectroscopy, and thermogravimetric analysis to investigate their structural, morphological, compositional, and optical properties. The crystallite size was determined to be 38.42 nm, while the particle size was nearly double, at 65.22 nm. The IO-NPs were further evaluated for their photocatalytic efficacy in degrading methyl orange (MO) and rhodamine 6G (R-6G), two common organic dye pollutants. The highest degradation efficiency of 99.42% was achieved for R-6G, while MO showed a degradation of 79.87% within 160 min. Photocatalytic experiments were conducted under varying conditions of catalyst dosage, initial dye concentration, and solution pH to optimize the degradation process. The recycling potential of the IO-NPs was also examined by performing the photocatalytic process over five cycles, demonstrating their reusability and potential for sustainable wastewater treatment.

Published: February 2025

Abstract
This article presents two types of the new convolutions for the Hartley integral transform associated with the Hermite functions, gives rise to the identification of some commutative and non-commutative Banach algebras, and to the Young inequalities which, in a certain sense, can be seen as the exceptional Young inequalities. Moreover, the solvability of a class of the integral equations is investigated, and their solutions in a series form can be obtained by using the constructed convolutions.
Analysis of the formation process of a natural fertilizer in the loess area

Published: February 2025

Abstract
In the Loess Plateau, farmers usually collect the surface soil of terrace sections for use as a fertilizer. Samples were taken at the Loess Plateau in Yan’an City to analyze the distribution patterns on the terrace section of different types, including different years (2, 6, and 10 years), slope aspects (shady slope and sunny slope), vertical heights (0.2, 1, and 1.8 m from the ground), and depths (0–1, 1–3, and 3–5 cm from the surface soil). The results showed that (1) with the increase in years, under the influence of natural factors such as temperature, sunlight, and moisture, the soil nutrients on the surface of terrace section were gradually activated and enriched, and the enrichment effect of nutrients on the 10-year terrace section was the most significant. (2) Under the influence of natural factors such as temperature and sunlight, as the depth of the terrace section from the soil surface increased, the values of available potassium and total nitrogen gradually decreased. The nutrients on the terrace section were mainly enriched in the surface soil and could be used as potassium and nitrogen fertilizers. (3) In the study area, when the heights from the ground surface were different, the differences in nutrients on the terrace section were not significant. The surface soil of the terrace section was measured to be rich in nutrients such as nitrogen and potassium. The research results confirmed the scientific nature of local farmers’ collection of fertilizers from the terrace section and have important theoretical reference value for the rapid ripening of raw soil in land remediation projects and the production of ecological fertilizers.

Cultural interaction and value pursuit: the Shijing in German culture
Authors: Yang Xinwen 
Published: February 2025

Abstract
In addition to being a treasure of Chinese literature, the Shijing is also an integral part of world literature. Its translation and dissemination in Germany have a history of nearly 300 years, reflecting Germany’s sustained attention to Chinese literary classics and highlighting the dialogue and interactions between the two cultures at different historical stages. The powerful textual interpretations and meaning-construction functions of the Shijing are key reasons for its enduring relevance in Germany. From Jakobson’s theory of translation semiotics, the interlingual translation of the Shijing into German can be divided into a direct symbolic conversion from Chinese to German and translation via a third language. Versions directly based on the original Chinese text undergo a process from intralingual translation to interlingual translation, ultimately achieving equivalence in difference between Chinese and German language and cultural information as distinct symbolic systems. German translators and scholars have approached the Shijing from the perspectives of cultural interpretation, literary criticism, and aesthetic analysis, conducting cross-cultural interpretations. Embedded within this are diverse value propositions based on local cultural and academic traditions, including promoting cultural understanding, embodying the Chinese imagination, shaping literary concepts, and fostering cultural exchange. Investigating the cultural interaction during the dissemination of the Shijing in Germany and the research value propositions of German academia contributes to examining the construction of Shijing Studies in Europe and promotes the study of the Chinese classics’ dissemination overseas.
The Long Shadow of Versailles: An Unusual Controversy on John Maynard Keynes between the German Ordoliberals Walter Eucken and Wilhelm Röpke
Authors: Horn Karen 
Published: February 2025

Abstract
Ordoliberalism and Keynesianism are not exactly known to fit hand in glove. Accordingly, the German economists Walter Eucken, head of the Freiburg School, and Wilhelm Röpke, from his Istanbul and Geneva exiles, were in near perfect agreement in their opposition to the interventionist “full employment” teachings of their English colleague John Maynard Keynes. An article by Röpke on Keynes in the Swiss newspaper Neue Zürcher Zeitung (NZZ) published in 1946, however, met with “fundamental objections” by Eucken, and a controversy took off. The bone of contention between the two colleagues and dissimilar friends was Keynes’s famous earlier critique of the Treaty of Versailles, and the lessons to be drawn for the post-World War II situation. This article tells the story of this unusual and puzzling controversy, quoting from the letters between the two, and contextualizes the exchange in order to make sense of it. It turns out that there was an economic, a human, and – most significantly – a political side to their disagreement. Eucken and Röpke assessed the economic development since 1919 somewhat differently, and Eucken felt compelled to defend Keynes against the heavy moral accusation of having contributed to the Nazi catastrophe. But perhaps most of all, he found it tactically unwise in 1946 to endorse arguments that would support an even harsher attitude by the Allies toward Germany after World War II. In a first translation, the article’s appendixes contain Röpke’s NZZ article that sparked the controversy, as well as the rejoinder by Eucken’s former student Valentin F. Wagner. A new, full translation of an earlier NZZ article by Röpke on Keynes in lieu of an obituary is also provided.
Multimodal imaging to identify brain markers of human prosocial behavior

Published: February 2025

How humans achieve such a high degree of prosocial behavior is a subject of considerable interest. Exploration of the neural foundations of human prosociality has garnered significant attention in recent decades. Nevertheless, the neural mechanisms underlying human prosociality remain to be elucidated. To address this knowledge gap, we analyzed multimodal brain imaging data and data from 15 economic games. The results revealed several significant associations between brain characteristics and prosocial behavior, including stronger interhemispheric connectivity and larger corpus callosum volume. Greater functional segregation and integration, alongside fewer myelin maps combined with a thicker cortex, was linked to prosocial behavior, particularly within the social brain regions. The current study demonstrates that these metrics serve as brain markers of human prosocial behavior and provides novel insights into the structural and functional brain basis of human prosocial behavior.Significance StatementThe objective of this study was to identify brain markers associated with human prosocial behavior using data from 15 major economic games and multimodal magnetic resonance imaging data. The results of the study suggest that specific brain indicators, including myelin density and resting-state inter-hemispheric functional connectivities, are associated with prosocial behavior. The use of a data-driven approach holds particular significance within the realm of social neuroscience, a field that grapples with a multitude of variables.

Published: February 2025

Background: One of the main reasons women prefer cesarean surgery is their fear of pain during natural process of childbirth. Neuraxial analgesia is a beneficial option for decreasing pain during natural childbirth. However, painless childbirth is still not widely accepted by parturient in developing countries compared to high-resource countries due to cultural issues and lack of knowledge. We investigated the causes of rejecting neuraxial painless childbirth in parturient admitted to the labor ward of our hospital.
Methods: A total of 567 parturient who declined neuraxial analgesia for painless labor were included in this single center cross-sectional study conducted between 2020 and 2022. The causes of refusal and level of knowledge were evaluated using a validated and reliable questionnaire.
Results: The main reasons for patients' refusal of neuraxial analgesia were fear of neuraxial complications, concern about insertion of the spinal needle, and worry about prolonging labor time following neuraxial analgesia, respectively. 51 participants had high, 134 had medium and 381 had low awareness level. Parturient who attended prenatal classes as well as those who used internet as a source of information had significantly higher levels of awareness.
Conclusion: Fear of neuraxial complications, spinal needle and delaying childbirth were the primary reasons for maternal rejection. The women's knowledge about neuraxial painless labor was inadequate
