Published: April 2024

AbstractAlthough there is increasing evidence suggesting that DNA methylation regulates seed development, the underlying mechanisms remain poorly understood. Therefore, we aimed to shed light on this by conducting whole-genome bisulfite sequencing using seeds from the large-seeded cultivar 'HZ' and the abortive-seeded cultivar 'NMC'. Our analysis revealed that the 'HZ' seeds exhibited a hypermethylation level compared to the 'NMC' seeds. Furthermore, we found that the genes associated with differentially methylated regions (DMRs) and differentially expressed genes (DEGs) were mainly enriched in the reactive oxygen species (ROS) metabolic pathway. To investigate this further, we conducted nitroblue tetrazolium (NBT) and 2,7-Dichlorodihydrofluorescein (DCF) staining, which demonstrated a significantly higher amount of ROS in the 'NMC' seeds compared to the 'HZ' seeds. Moreover, we identified that the gene LcGPX6, involved in ROS scavenging, exhibited hypermethylation levels and parallelly lower expression levels in 'NMC' seeds compared to 'HZ' seeds. Interestingly, the ectopic expression of LcGPX6 in Arabidopsis enhanced ROS scavenging and resulted in lower seed production. Together, we suggest that DNA methylation-mediated ROS production plays a significant role in seed development in litchi, during which hypermethylation levels of LcGPX6 might repress its expression, resulting in the accumulation of excessive ROS and ultimately leading to seed abortion.
Nutrient depletion and heat stress impair the assimilation of nitrogen compounds in a scleractinian coral
Authors: Crehan Oscar , Davy Simon K. , Grover Renaud , Ferrier-Pagès Christine 
Published: April 2024

ABSTRACT
Concentrations of dissolved nitrogen in seawater can affect the resilience of the cnidarian–dinoflagellate symbiosis to climate change-induced bleaching. However, it is not yet known how the assimilation and translocation of the various nitrogen forms change during heat stress, nor how the symbiosis responds to nutrient depletion, which may occur due to increasing water stratification. Here, the tropical scleractinian coral Stylophora pistillata, in symbiosis with dinoflagellates of the genus Symbiodinium, was grown at different temperatures (26°C, 30°C and 34°C), before being placed in nutrient-replete or -depleted seawater for 24 h. The corals were then incubated with 13C-labelled sodium bicarbonate and different 15N-labelled nitrogen forms (ammonium, urea and dissolved free amino acids) to determine their assimilation rates. We found that nutrient depletion inhibited the assimilation of all nitrogen sources studied and that heat stress reduced the assimilation of ammonium and dissolved free amino acids. However, the host assimilated over 3-fold more urea at 30°C relative to 26°C. Overall, both moderate heat stress (30°C) and nutrient depletion individually decreased the total nitrogen assimilated by the symbiont by 66%, and combined, they decreased assimilation by 79%. This led to the symbiotic algae becoming nitrogen starved, with the C:N ratio increasing by over 3-fold at 34°C, potentially exacerbating the impacts of coral bleaching.
“Canada Is Where You Belong. Poland Is The Past”: Images of Polish History and Culture in Heather Kirk’s Warsaw Spring
Authors: Świetlicki Mateusz 
Published: April 2024

Polish characters appear in both mainstream Canadian books and children’s literature, but they usually function as either side characters or antagonists. The fiction of Heather Kirk is a noteworthy exception. This Canadian writer, who spent two years in Warsaw in the late 1970s working as a lecturer at the University of Warsaw, devoted her first two young adult problem novels, Warsaw Spring (2001) and A Drop of Rain (2004), to Polish Canadians and Polish history and culture. The article argues that in Warsaw Spring Kirk shows that the teenage protagonist has to experience the history and culture of the country of her ancestors before she can incorporate it into her own transcultural repository of memory. The article demonstrates how the experience of traveling to Poland and meeting with the representatives of the older generations, often survivors of the Second World War and communism, influences the formation of the protagonist’s Polish Canadian identity and cultural memory. Finally, the article shows that despite Kirk’s praiseworthy attempts to introduce young readers to Polish history, the way she portrays Poland is problematic because the country emerges as an exotic, post-Second World War heritage site of memory for Eva, a Canadian teenager whom all of the novel’s Poles seem to treat as superior.
Własność podzielona w stosunkach wiejskich Księstwa Warszawskiego i Królestwa Kongresowego (do uwłaszczenia) w świetle akt notarialnych
Authors: Pomianowski Piotr Z. 
Published: April 2024

Celem artykułu jest analiza chłopskich praw do ziemi w okresie Księstwa Warszawskiego i Królestwa Kongresowego (do uwłaszczenia). W centrum zainteresowania znajduje się własność podzielona. Ta instytucja o średniowiecznej genezie przewiduje rozdzielenie atrybutów prawa własności pomiędzy właściciela zwierzchniego (np. dziedzica dóbr ziemskich) a właściciela podległego (np. chłopa uprawiającego nadział ziemi w dobrach ziemskich). Status prawny właściciela podległego od statusy dzierżawcy (itp.) odróżnia rzeczowy charakter jego uprawnień.
Problem istnienia własności podległej na wsi Księstwa Warszawskiego (po dekrecie grudniowym) i Królestwa Kongresowego (zwłaszcza przed ukazem czerwcowym) bywał w przeszłości przedmiotem kontrowersji. Zwłaszcza historiografia Polski Ludowej kwestionowała istnienie tej instytucji w interesującym nas okresie. Autor niniejszego artykułu wykazuje, że własność podzielona funkcjonowała w znacznej skali w pierwszej połowie XIX w. na centralnych ziemiach polskich, choć precyzyjne określenie tej skali na obecnym etapie badań nie jest możliwe.

Published: March 2024

Purpose: This paper aims to analyse the impact of entrepreneurial orientation (EO) through the relationship of transformational leadership (TL) for the development of dynamic capabilities (DC) for organisational innovation.
Methodology/Approach: Under a qualitative method, and a single case study strategy, data were obtained from interviews with 15 senior managers and leaders of innovation activities; the document review and data triangulation method was used to analyse causality relations proposed in the theoretical framework.
Findings: The empirical results confirm that the EO and TL have a positive relationship with the development of innovation capabilities. Findings indicate that risk-taking, proactiveness, assimilation, and exploitation of internal and external knowledge remain the main difficulties in improving innovation capabilities and adaptability in the technological environment.
Research Limitation/implication: The present paper gathered data from a specific organisation in the field of EO. The research allowed us to better understand the incidence of EO, TL, and DC regarding the relationship between variables, and it should be considered a potential source for enhancing innovation management capabilities.
Originality/Value of paper: This work is the first that integrates the concepts of EO with other related disciplines into a single case strategy, within a specific entrepreneurship and innovation ecosystem context in a large automotive industry.

Published: April 2024

BACKGROUND
Extraction of impacted third molars often leads to severe complications caused by damage to the inferior alveolar nerve (IAN).
AIM
To proposes a method for the partial grinding of an impacted mandibular third molar (IMM3) near the IAN to prevent IAN injury during IMM3 extraction.
METHODS
Between January 1996 and March 2022, 25 patients with IMM3 roots near the IAN were enrolled. The first stage of the operation consisted of grinding a major part of the IMM3 crown with a high-speed turbine dental drill to achieve sufficient space between the mandibular second molar and IMM3. After 6 months, when the root tips were observed to be away from the IAN on X-ray examination, the remaining part of the IMM3 was completely removed.
RESULTS
All IMM3s were extracted easily without symptoms of IAN injury after extraction.
CONCLUSION
Partial IMM3 grinding may be a good alternative treatment option to avoid IAN injury in high-risk cases.

ABSTRACTThe phenomenon of cases of diabetes mellitus from year to year continues to increase. According to the International Diabetes Federation (2019) revealed that the number of diabetes mellitus patients in the world in 2019 was 829 million and it is estimated that in 2040 the number of diabetes patients will increase 1.5 times. The prevalence of diabetes mellitus in the Special Region of Yogyakarta continues to increase every year. The prevalence of Diabetes Mellitus in DI Yogyakarta Province, in 2020, is 5.59 percent. This figure has even increased compared to the results of research seven years earlier in 2013, namely 3.4 percent.To determine the effect and differences in increasing diabetic self-management before and after intervention through social support with peer leaders among people with type II DM in the elderly Posyandu.This research used a quasi-experimental design with a pre-test and post-test nonequivalent control group design. The study population was all type II diabetes sufferers at the Elderly Posyandu in Ngentak, Bangunjiwo, Kasihan, Bantul, DI Yogyakarta from September 2022 to June 2023 with a sample size of 50 respondents using purposive sampling. The data collection instrument used a respondent characteristic questionnaire, and a diabetes self management knowledge questionnaire. Data were analyzed univariately and bivariately with q-square test (95% CI). In this design, the experimental group underwent an initial selection in the form of a pre-test, namely the assessment of diabetic self-management in type II DM patients before the social support intervention with peer leaders was carried out, then a post-test was carried out after the intervention was given.There is an effect of increasing diabetic self-management knowledge, seen from the difference in the mean value from pretest to posttest of only 10,5 in the respondents' answers. There was a difference from the pretest to the posttest scores, seen from the significance of p = 0.000 (p <0.05) after being given interventions about social support with peer leaders among people with type II DM in the elderly Posyandu.There are influences and differences in the form of increasing diabetic self-management after being given intervention to fellow DM type II sufferers at the Elderly Posyandu in Ngentak hamlet, Bangunjiwo, DI Yogyakarta Keywords: Diabetic self management, social support, peer leader, type II diabetic
Exercise increases TCA intermediate concentrations during low‐calorie diet independent of insulin resistance among women with obesity
Authors: Ragland Tristan J. , Malin Steven K. 
Published: April 2024

AbstractTricarboxylic acid cycle intermediates (TCAi) have been proposed to act as myokines that influence energy metabolism. We determined if 2‐weeks of low‐calorie diet with interval exercise (LCD + INT) would increase TCAi more than a low‐calorie diet (LCD). Twenty‐three women were randomized to 2‐weeks of LCD (n = 12, 48.4 ± 2.5 years, 37.8 ± 1.5 kg/m2, ~1200 kcal/d) or LCD + INT (n = 11, 47.6 ± 4.3 years, 37.9 ± 2.3 kg/m2; 60 min/d supervised INT of 3 min 90% & 50% HRpeak). TCAi and amino acids (AA) were measured at 0 min of a 75 g OGTT, while glucose, insulin, and FFA were obtained at 0, 30, 60, 90, 120, and 180 min to assess total area under the curve (tAUC180min) and insulin resistance (IR; tAUC180min of Glucose × Insulin). Fuel use (indirect calorimetry) was also collected at 0, 60, 120, and 180 min as was fitness (VO2peak) and body composition (BodPod). Treatments reduced weight (p < 0.001), fasting RER (p = 0.01), and IR (p = 0.03), although LCD + INT increased VO2peak (p = 0.02) and maintained RER tAUC180min (p = 0.05) versus LCD. Treatments increased FFA tAUC180min (p = 0.005), cis‐aconitate, isocitrate, and succinate (p ≤ 0.02), as well as reduced phenylalanine and tryptophan, cysteine (p ≤ 0.005). However, LCD + INT increased malate, citrate, α‐ketoglutarate, and alanine more than LCD (p ≤ 0.04). Thus, INT enhanced LCD effects on some TCAi in women with obesity independent of IR.

Published: April 2024

Abstract

Objectives
The prevalence of diabetes mellitus type 2 (DMT2) is increasing exponentially worldwide. DMT2 patients have been found to be at a higher risk for bone fractures than the healthy population. Hence, improving our understanding of the impact of antidiabetic drugs on bone metabolism is crucial.

Methods
A descriptive, retrospective study involving 106 patients receiving six groups of antidiabetic drugs: insulin; dipeptidylpeptidase four inhibitors (DPP4i); glucagon-like peptide type 1 receptor agonists (GLP1ra); sulfonylureas; sodium-glucose cotransporter two inhibitors (SGLT2i); and pioglitazone, in which osteocalcin (OC), bone alkaline phosphatase (BAP) and C-terminal telopeptide of collagen type 1 or beta-crosslaps (β-CTx) were determined.

Results
β-CTx concentrations were higher in the patients treated with pioglitazone, as compared to patients treated with DPP4i (p=0.035), SGLT2i (p=0.020) or GLP1ra (p<0.001). The lowest β-CTx concentrations were observed in the patients treated with GLP1ra.

Conclusions
Bone remodeling is influenced by the type of antidiabetic drug administered to DMT2 patients. In our study, the patients who received pioglitazone showed higher β-CTx concentrations, as compared to patients treated with other types of antidiabetic drugs. This finding highlights the convenience of avoiding these drugs, especially in postmenopausal women with DMT2. GLP1ra drugs were associated with the lowest β-CTx concentrations, which suggests that these agents could exert beneficial effects on bone metabolism.

Published: April 2024

Abstract
We report the Korean records for comet C/1652 Y1, which have not been introduced in previous studies on historical comets. According to Korean historical documents, this comet, described as bai xing (white star, in literal) or ke xing (guest star, in literal), was observed with the naked eye for 22 days from December 19, 1652 to January 9, 1653. In this study, we first cross-checked the records of comet C/1652 Y1 among Korean documents and presented the translations in the Appendix for future reference. We then compared the Korean observations with the orbital path determined from calculations using the orbital elements provided by Marsden (1983. Catalog of cometary orbit. Hillside: Enslow Publishers). We also compared the illustrations depicted by Weigelius and Schiltero (1653. Commentatio astronomica de cometa novo qui sub finem anni 1652 lumine sub obscuro nobis illuxit. Jenae: Typis Georgii Sengenvvaldi) and by Hevelius (1668. Cometographia, Totam Naturam Cometarum; Exhibens. Gedani: Typis Auctoris, & Sumptibus, Simon Reiniger). We found that the Korean observations show discrepancies with the orbital path calculated by Marsden and the illustration of Weigelius and Schiltero, particularly near the end of the observation period. In conclusion, we believe that this study will contribute to improving the orbital path calculation of comet C/1652 Y1.
Numerical and experimental analysis of ballistic performance in hybrid soft armours composed of para-aramid triaxial and biaxial woven fabrics
Authors: Pinkos Justyna , Stempien Zbigniew , Małkowska Magdalena 
Published: April 2024

Abstract
This article presents the results of numerical and experimental research on the ballistic performance of soft packages composed of biaxial and triaxial fabrics in various hybrid configurations. The main objective of these studies was to prove the hypothesis that a hybrid package composed of biaxial fabrics, on the impact side of a projectile, and triaxial fabrics, on the backside, exhibits greater ballistic efficiency than a package entirely composed of biaxial or triaxial fabrics. The research was conducted by shooting packages consisting of 30 layers of fabrics using a Parabellum 9 × 19 full metal jacket projectile, with a striking velocity of 380 m/s, after placing the packages on a Roma No.1 plasticine substrate. The analysis involved the deformation depth of the plasticine substrate and the perforation ratio of the packages. Optimisation studies revealed that the optimal package configuration should consist of 9 layers of biaxial fabrics on the projectile impact side and 21 layers of triaxial fabrics on the backside, indicating a biaxial to triaxial fabric ratio of approximately 1:3.
Government Spending Between Active and Passive Monetary Policy: An Invariance Result
Authors: Laumer Sebastian , Philipps Collin 
Published: April 2024

Abstract
This paper develops a new approach to analyze the relationship between the government spending multiplier and monetary policy. We embed measures of monetary policy activism into a nonlinear SVAR model. Our model allows the central bank to adjust its monetary policy regime in response to the economic conditions that arise after government spending shocks. We find that, regardless of the monetary policy regime at the time of a spending shock, the central bank adjusts its regime quickly and responds actively towards inflation only a few quarters after the shock hits the economy. This rapid response of monetary policy leaves medium-run multipliers ultimately unaffected by whether the initial regime was active or passive. For both initial regimes, our five-year multiplier estimates lie between 1.2 and 1.5. An apparent exception to this result is the zero lower bound period between 2008Q4 and 2015Q4-during which monetary policy kept nominal interest rates at zero. Our multiplier point estimates for that era are consistently larger than unity.

Nationalism, Italy and the Exhibition of the Holocaust: Findings of a Study on the Recently built Museums of Campagna and San Donato
Authors: Posocco Lorenzo , Angeletti Valerio , Meghnagi Micol 
Published: April 2024

Abstract
In recent years, Italy has seen a proliferation of Holocaust Museums and Memorials. This article focuses on two recent additions: the Museum of the Twentieth Century and the Shoah in San Donato Val di Comino (Frosinone), and the Memory and Peace Museum Giovanni Palatucci Study Center in Campagna (Salerno). It uses qualitative methods including in-depth interviews, direct observation, analysis of information panels, other audio and visual elements, and is guided by a theoretical framework rooted in theories of nationalism. The research findings show that these museums present an overly positive narrative of Italy’s role in the Holocaust lacking critical examination and perpetuating the myth of the “good Italian” already identified by other scholars. The museums emphasize favourable conditions for Jewish internees without considering factual evidence that could have provided a more balanced perspective. Additionally, they fail to acknowledge Italian collaboration with Nazi Germany, both, at the exhibition sites and elsewhere. Both museums highlight a Christian salvific narrative, stressing the role of Christian Italians saving Jews, and perpetuating stereotypes of Jews as passive victims. Additionally, Jews are excluded from the notion of “Italianness” and portrayed as “others.” Also, fascism is excluded, deemed incompatible with the idealized Italian Christian civilization proposed by the museums.
Post-Pandemic Challenges of Textile Industry Workers in India: Analysis of Social Security Laws of Select Asian Countries
Authors: Gahlot Sheetal , Singh Kanwal D. P. 
Published: April 2024

Abstract
The COVID-19 pandemic ensued a challenging period for global health; however, the loss of livelihoods throughout the lockdown also led to a significant economic issue that warranted a reassessment of the existing socio-economic structures. Manufacturing lines were severely impeded, particularly in the Indian textile industry, the second-largest employer and labour-intensive industry. The initial lockdown did not provide manufacturers enough time to prepare for the impending catastrophe, compelling many to shut down their operations. The above circumstances highlighted the lack of resilient social security laws in India.
Despite initiatives like the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA), the Employees’ Provident Fund (EPF) scheme and other initiatives like grain distribution to families below the poverty line, lack of economic security came to the forefront. There is a need to have a competent social security legal framework in India to ensure economic stability for all that would fall in line with the noble ideas of the framers of the Constitution as enshrined in the Directive Principles of State Policy, the guiding light for all state action in India. India has not ratified the International Labour Organizations Social Security (Minimum Standards) Convention of 1952. The focal area of the current research would be to look into the sufficiency of the legal framework (International and National) to protect the economic interests of the workers.
The authors examine the following: 1. Examine the Code on Social Security, 2020 passed by the Indian legislature interpreting it in light of the COVID-19 pandemic and its effect on textile manufacturing in India along with other steps initiated by the government for the textile industry. 2. Carry out a comparative analysis of the social security laws of other Asian countries (Bangladesh, Vietnam, and China) to carve out best practices that can be adopted in India. 3. Analyse and contrast the statistical data of the four predominant textile manufacturing and exporting economies on selected parameters.
