Published: December 2024

The most common endocrine condition in women of reproductive age is polycystic ovary syndrome (PCOS). Syndrome of Polycystic Ovaries in premenopausal women is characterized by polycystic ovaries, dysmenorrhea, and hyperandrogenism.Women often experience infertility due to the hormonal imbalance linked to polycystic ovarian syndrome, which has detrimental effects on their physical, mental, and social well-being.This study aims to survey the biochemical markers of some hormones in polycystic ovary syndrome, such as follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin, estradiol, and testosterone in the blood of residents of Dhi Qar city with polycystic ovary syndrome (polycystic ovary syndrome). Bioinformatics software predicted the ATG5-binding microRNA, and the dual-luciferase reporter assay was used to determine their targeting relationship. Furthermore, quantitative real-time polymerase chain reaction (qRT-PCR) was used to evaluate the expression of ATG5 in the ovary. For this purpose, the blood serum consisting of 106 samples will be divided into (55, 25, and 26) pre-menopausal patients, post-menopausal patients, and a healthy control group, respectively.According to the results, the average serum LH levels were higher in both groups of patients compared with healthy controls, and the difference was significant (P = 0.001). In postmenopausal patients, the mean serum FSH levels were significantly greater (P = 0.001) than in the other groups. While both patient groups' average serum prolactin levels were lower than those of the healthy controls, the difference was not statistically significant (P = 0.396). The average serum estradiol levels were significantly lower (p<0.01) in postmenopausal patients compared to the other groups. The average ATG5 gene expression was significantly increased (p<0.01) in both groups of patients compared with healthy controls.

Water security, safety, availability and sustainability of water supply are increasingly problematic and difficult across the planet. Safe and rapid methods have been developed to purify water from cationic pollutants. New imidazole-derived fluorescent sensors, 2-(4,5-diphenyl-1-(p-tolyl)-1H-imidazol-2-yl) phenol (TS) and 2-(1-(4-methoxyphenyl)-4,5-diphenyl-1H-imidazol-2-yl) phenol (AS), have been synthesized and characterized, and their possibility as fluorescence sensors for copper (II) has been examined. In CH3CN/H2O (90 v/v), the TS and AS revealed a noticeable an electronic band at 320.00 nm and fluorescence band at 460.90 nm. The ratio metric alterations in the absorption and fluorescence spectra of TS and AS due to the dative covalent bond between them and the copper (II) were shown by the findings of copper (II) titration. The sensing mechanism was validated by optical investigations and FT-IR spectra. In mixed solvent solutions, the selectivity of TS and AS to copper (II) as fluorescent sensors has been demonstrated, with sensitivity as low as 0.09 and 0.28 µM, significantly less than the limit permitted via the US EPA for drinking water (2.00 µM). The identification limits of TS and AS were assessed to be 0.05 and 0.50 µM, respectively, using the spectrophotometric procedure. Stoichiometry binding between TS and AS with copper (II) was found to be 2:1 (tetrahedral structure) as indicated by Job's method.

The increase in the frequency of psychiatric disorders is increasingly observed in patients diagnosed with cancer. Brain tumors are often associated with psychiatric symptoms such as mood symptoms, psychosis, memory problems, personality changes, anxiety, or depression. This study investigates what types of manifestations are present in patients with brain tumors, highlighting the connection with the location of the tumor. We conducted a clinical study on a sample of 91 patients diagnosed with primary brain tumors, hospitalized at the "Prof. Dr. Nicolae Oblu Emergency Clinical Hospital," Iași, Romania, between 2011 and 2023. Demographic data, type, and location of tumors were collected from the patients' medical records. Patients underwent detailed neuropsychological evaluations to identify psychiatric manifestations. Statistical analyses were performed to determine the prevalence of these manifestations and the correlations between tumor location and the severity of psychiatric symptoms. Our results show a significant prevalence of psychiatric disorders among patients with brain tumors, with notable differences between genders and types of manifestations. Organic personality disorders and mixed anxiety and depression disorders were among the most common. Additionally, a correlation was observed between the location of tumors in the frontal lobe and the severity of psychiatric symptoms. Conclusions: The research highlights the increased frequency of psychiatric symptoms in patients with brain tumors, especially when the tumor is located in the frontal lobe. These observations emphasize the relevance of a multidisciplinary approach in the management and treatment of these patients, including both cancer therapy and psychiatric support services.

Published: December 2024

Magnetoencephalography (MEG) has become a pioneering technology in Brain-Computer Interfaces (BCIs) for neurorehabilitation, which significantly improves communication and motor rehabilitation for people with neurological conditions, especially stroke survivors. MEG-based BCIs allow users to regain control over their motor and cognitive functions by providing precise temporal and spatial resolution for detecting neural activity. The MEG has several benefits including reduced distortion from the skull and scalp, its non-invasive nature, and the ability to capture deep brain activity, all of which enhance the effectiveness of BCI systems. This study focuses on classifying motor and cognitive tasks using various models, including Recurrent Neural Networks (RNNs), one-dimensional Convolutional Neural Networks (1DCNNs), and a hybrid approach. The effectiveness of the models in classification tasks was evaluated using various metrics such as accuracy, recall, precision, and F1-score. Significantly, the hybrid model exhibited enhanced performance relative to the other models, achieving marked improvements in both classification accuracy and robustness. These results underscore the promise of MEG BCI technology for neurorehabilitation and stress the need for the development of sophisticated classification models to support the recovery of motor and cognitive abilities in people with neurological conditions. This study adds to the expanding research focused on enhancing the quality of life for affected individuals by utilizing innovative BCI solutions, leveraging the unique capabilities of MEG technology to enable more effective neurorehabilitation interventions.

Authors: Calciu Claudia Z , Păduraru Ancuța E , Soponaru Camelia
Published: December 2024

Dissociative experiences are common in both clinical and general populations. In this study, we had the aim to explore the presence of any differences in the utilization of dissociative mechanisms between two types of populations, namely clinical and non-clinical and also to see if within each group there are differences in the use of these mechanisms. The research group consisted of 216 participants, of which 176 (81.5%) were non-clinical participants and 40 (18.5%) participants with a clinical diagnosis. We used two questionnaires, namely the Detachment and Compartmentalization Inventory and the Dissociative Experiences Scale and a demographic data collection tool. Our results showed that clinical participants scored significantly higher than non-clinical participants on detachment, absorption and compartmentalization. The data also showed that there are significant differences between the use of detachment, compartmentalization and absorption, separately for clinical and non-clinical participants. Detachment, absorption and compartmentalization are dissociative mechanisms used by the clinical as well as the non-clinical population, with no differences between groups in terms of gender. Age appears to influence the use of these mechanisms in the non-clinical population in that they are used less with advancing age. Absorption tends to be used less by married than unmarried people in the non-clinical population. The results of our study converge towards the theory which support the idea of "healthy dissociation".
Exploring Syntactic Ambiguity and Deep Structure Transformations in the translations Rumi's Mystical Poetry: A Generative Grammar Perspective
Authors: Farwa Ali  , Zuhra Ahmed  , Maria Abbasi  , Muhammad Yasir Khan
Published: December 2024

This paper aims at understanding how the element of mysticism in the selected work of Rumi can be explored via linguistic theory principles such as generative grammar and syntactic ambiguity. By deconstructing surface and deep structures, this study unveils the intricate interplay between language and meaning in six poems: “The Guest House”, “The Marriage of True Minds”, “Where There is Ruin”, “Silence is the Language of God”, “Only Breath” and “Out Beyond Ideas”. These poems are analyzed to decode the mystical meanings hidden in linguistic ambivalences. In “The Guest House”, the metaphor that applies to human life as a ‘guest house’ is studied under the view of syntactic doublet, which corresponds to Sufi conceptions of tenderness and receptiveness. In “The Marriage of True Minds”, love and unity are aligned, which shows how conditional syntax accords with the Sufism perspective of love. This research demonstrates how Rumi’s syntactical creativity supports the theoretical frameworks of multiple readings under the light of mystic wisdom. The insights established in this research yield the concept of analyzing the structure of Rumi’s poem, as well as the relation between language and spirituality.

Published: December 2024

Background: Appendicitis is the third most common cause of emergency abdominal surgery worldwide, but diagnosis remains challenging. Clinical scoring systems like Alvarado and RIPASA aim to improve diagnostic accuracy. While the Alvarado score is widely accepted, it is more commonly applied in Western populations. In contrast, the RIPASA score was developed for Southeast Asian populations, reflecting demographic variations in appendicitis presentation. This study compares the accuracy of the RIPASA and Alvarado scores against histopathological findings, the traditional gold standard.

Methods: A prospective, comparative study was conducted on 255 patients with suspected acute appendicitis. Upon admission, both RIPASA and Alvarado scores were calculated. Diagnostic performance was evaluated using sensitivity, specificity, PPV, NPV, and overall accuracy. Concordance between scoring systems was analyzed with Cohen’s Kappa, and McNemar’s test assessed statistical significance in performance differences.

Results: The RIPASA score demonstrated superior sensitivity at 92% compared to 85% for Alvarado, with both scoring 75% specificity. The PPV for RIPASA was 96%, marginally higher than Alvarado’s 95%, indicating high accuracy in detecting true positives. RIPASA’s NPV was 75%, yielding fewer false negatives than Alvarado. McNemar’s test showed a significant difference (p < 0.05) favoring RIPASA, and Cohen’s Kappa indicated moderate to substantial agreement (0.6–0.8). Conclusion: RIPASA offers better diagnostic performance than Alvarado, particularly in multicultural settings, due to its higher sensitivity and comparable specificity. While both scores have moderate NPVs, additional diagnostic methods may be necessary for complex cases. Further studies are needed to validate these findings across diverse populations

A group of cancerous diseases of the blood and bone marrow known as leukemias are life-threatening. It is crucial to recognize the leukemic cells lineage when making a diagnosis of leukemia because treatment for the disease depends on whether the cells are myeloid or lymphoid. As per the Observation There is total 300 blood samples in which 150 were leukemic patients and 150 were healthy person. The genotype distribution frequencies of the XRCC1 gene's SNP rs25487 results demonstrate a highly significant connection between heterozygous (GA) rs25487 of the XRCC1 gene and an increased risk of leukemia up to 2-folds (OR=2.52; 95% CI=1.51- 4.20; p=0.0004). The scenario is identical when it comes to homozygous mutant (AA), which also shown a highly significant connection with a reduced risk of leukemia and performs a protective role (OR=0.40; 95% CI=0.23-0.70; p=0.0014). The combined genotype model of mutant and hetero of rs25487 demonstrated a weakly non-significant correlation with leukemia (OR=1.14; 95% CI=0.72-1.82; p=0.5618). This study intended to look at the connection between leukemia risk regulation and XRCC1 polymorphisms, as well as the conceivable relationship between leukemia patients and the XRCC1 polymorphism (rs25487). It was determined that rs25487 was linked to a higher risk of leukemia in people

A Study on the Interaction Between Aesthetics and Cultural Identity
Authors: Ye Zihan
Published: December 2024

Aesthetics and cultural identity are significant topics in contemporary cultural studies. As the study of beauty and sensory experience, aesthetics has long surpassed the mere aesthetic experience to become a central mode of cultural expression and self-awareness. At the same time, cultural identity, as an individual's or group's recognition and sense of belonging to their culture, exhibits dynamic and pluralistic characteristics. In the context of globalization and cross-cultural communication, the interaction between the two has become increasingly complex, driving the reconstruction and innovation of cultural identity. This paper explores the interaction between aesthetics and cultural identity, analyzing its multi-dimensional expression in visual arts, literature, performing arts, and other fields. It reveals how this interaction shapes cultural identity and its transformation in the contemporary context. The study points out that aesthetics not only provides a platform for the expression of cultural identity but also facilitates the flow and reconstruction of cultural identity in cross-cultural exchanges. Future research could further explore the profound impact of digital aesthetics, virtual reality, and postmodern art on the construction of cultural identity.

Published: December 2024

Ships are the preferred transportation fleet for export-import activities compared to air transportation, because of their large carrying capacity, making them relatively more profitable. Ships without cargo to sail safely will add ballast water as a stabilizer. Ballast water often carries a variety of foreign microorganisms that can harm the landfill ecosystem. On September 8, 2017, the ballast Water Management Convention (BWMC) was enacted, to prevent the spread of pathogenic microbes that are very harmful to health and the environment. The purpose of the study was to determine the understanding of private academy cadets on the provisions of BWMC. Data were collected using questionnaires and in-depth interviews, then descriptive analysis was carried out. Respondents were cadets of private maritime academy in Central Java, a total of 35 respondents. 6 respondents were excluded because they gave dishonest answers, so the sample used was 29. From the conclusion that there were still many respondents who did not understand the provisions of BWMC, it was evident from the respondents' answers to several questions that none of them were correct. Such as the question of when the BWMC was promulgated, when Indonesia ratified the BWMC, and the question of the D-1 Standard and the D-2 Standard of the BWMC. However, there are 13.79% of respondents already have a concern about the dangers of ballast water and the importance of immediately handling ballast water. Our suggestion is to disseminate information to private academy cadets through seminars, special training on ballast water, or inclusion in marine pollution course materials.

Published: December 2024

The islands in Indonesia can only be connected by sea routes between islands. Sea is not dividing, but uniting the  various islands, areas and regions of Indonesia. Only through a nexus between the islands, between the beach, the unity of Indonesia can be realized. The cruise that connects the islands, was once the lifeblood of unifying the nation and the State of Indonesia. Cargo distribution is one of the biggest problems that slows down economic development in several regions, especially in eastern Indonesia. This creates a price differential between the two regions, with prices in the east being higher than in the west. In order to tackle this phenomenon, Indonesia government has launched several policies that are expected to force out economic equality for all regions especially and trigger the growth in peripheral area. The imbalance progress of regional development makes the sufficient infrastructure facility only available in western region especially in Java region. The propose of this articel is to identify government programs that are appropriate for the conditions of service gap in the sea transportation regions of Indonesia. The developing from peripheral regions, improving human quality life, and economic self-reliant becomes the foundation for the government to implement the Public Service Obligation project by issued the Sea-Toll Road program for reducing the economic disparity, inequality, and trigger the economic growth which characterized as a maritime country. However, in the implementation process, sea tollway programs face various challenges. Shipping of Short Sea Shipping (Coastal Shipping) as a backbone of national goods transportation has not realized.

Amaç: Sanal gerçeklik, son dönemlerde kullanımı yaygınlaşan interaktif, etkili ve eğlenceli bir eğitim aracıdır. Sanal gerçeklik sağlık alanında mesleki eğitimlerde yaygın olarak tercih edilirken hasta eğitiminde kullanımına ilişkin çalışmalar oldukça sınırlıdır. Cerrahi işlemler öncesi hasta eğitiminde sanal gerçeklik kullanımı, hastaların kaygısını azaltarak bilinçli karar vermeyi, tedaviye uyumu, hasta memnuniyeti ve bakım kalitesini arttırmaktadır. Bu kapsam araştırmasının amacı, cerrahi işlemlerde hasta eğitiminde sanal gerçeklik kullanan araştırmaların sonuçlarını incelemektir.
Yöntem: PubMed, CINAHL, Cochrane Library, Scopus veri tabanları ve Google Akademik’de, “sanal gerçeklik, hasta eğitimi, cerrahi işlemler, ameliyat öncesi dönem” anahtar kelimeleri ile Ocak 2017-Haziran 2022 arasındaki araştırmalar tarandı. Bu kapsam derlemesinde araştırma kriterlerini karşılayan, 4 randomize kontrollü çalışma, 1 vaka kontrol çalışması, 2 pilot çalışma ve 2 olgu sunumu ele alındı. Araştırmanın örneklemini ise bu 9 araştırmadaki 602 hasta oluşturdu.
Bulgular: Cerrahi işlemler öncesinde hasta eğitiminde sanal gerçekliğin kullanıldığı araştırmalar incelendiğinde, hastalık ve cerrahi işleme ilişkin eğitim verildiği saptanmıştır. Araştırma bulgularına göre, eğitim sonrası hastaların karar verme, tedavi ve bakım sürecine aktif katılımlarının sağlandığı, anksiyete ve ağrı düzeylerinin azaldığı, memnuniyet ve bilgi düzeylerinin arttığı, erken iyileştikleri sonucuna varılmıştır.
Sonuç: Sanal gerçeklik, hasta eğitiminde etkin, uygulanabilir ve hasta sonuçlarını iyileştiren bir yöntem olarak kabul edilebilir. Cerrahi işlemlerde hasta eğitiminde sanal gerçekliğin kullanıldığı araştırmaların arttırılması ve bu konuda hemşirelik alanında çalışmaların yapılması önerilmektedir.

Published: December 2024

To increase the production of biogas from an appropriate substrate, anaerobic co-digestion techniques are required. Methane generation and process stability can be enhanced by co-digesting animal dung and suitable biomass with a low carbon content. The objective of the study is to determine the proximate parameters and compare the biogas generation from a sample of plants sown with cow manure and leaves of Ziziphusspina. Over the course of 42 days, the experiment was conducted using a homemade anaerobic digester in the lab. Even yet, the amount of biogas produced by the plant sample was not as high as that produced by the plant sample that was fertilized with cow manure.For additional advantageous uses, such as the creation of biofertilizers, the physico-chemistry of fresh samples and spent slurries in the biodigesters might be investigated. This work has potential applications in underdeveloped nations, particularly in rural areas with abundant biological waste and limited access to energy.
Calculation of Deuteron Interactions within Microcracks of a D2 Loaded Crystalline Lattice at Room Temperature
Authors: Frisone Fulvio
Published: December 2024

We have analysed the possibility that the coefficient of lattice deformation, linked to the formation of microcracks at room temperature and low energies, could influence the process of fusion. The calculated probability of fusion within a microcrack, in the presence of D2 loading at room temperature and for impure metals, shows moderately elevated values compared with the probability of fusion on the surface. For all the temperatures in the 150–350 K range and for all the energies between 150 and 250 eV, the formation of microcracks increases the probability of fusion compared to non-deformed lattices, and also reduces the thickness of the Coulomb barrier. Using the trend of the curve of potential to evaluate the influence of the concentration of impurities, a very high barrier is found within the pure lattice (J ≈ 0.25%). However, under the same thermodynamic conditions, the probability of fusion in the impure metal (J ≈ 0.75%) could be higher, with a total energy less than the potential so that the tunneling effect is amplified. Finally, we analysed the influence of forced D2 loading on the process.
Theory of Fusion During Acoustic Cavitation in C3D6O Liquid
Authors: Fu-Sui Liu , Hou Yumin , Chen Wan-Fang
Published: December 2024

This paper demonstrates that an exact calculation for transition probability of deuteron under the phonon–deuteron interaction leads to violation of Fermi golden rule. Considering the violation of Fermi golden rule, the zero-point oscillation, and the energy uncertainty relation, this paper demonstrates that the neutron emission during acoustic cavitation comes from D(entered)–D(entered) fusion in C3D6O liquid instead of in cavitation vapor bubbles. This paper gives some predictions. The most important prediction is that the water can be taken as energy source producing fusion instead of C3D6O liquid.
Hot and Cold Fusion for Energy Generation
Authors: Nagel David J.
Published: December 2024

Sixty years of research on hot fusion have cost more than $ 20 B. Only one of the dozens of experiments has barely reached breakeven, the point at which the energy produced is equal to the energy spent for its production. Twenty years of work on “cold fusion” cost less than $ 0.2 B. Energy amplifications exceeding 10 for the palladium–deuterium system, and more than 100 for the nickel–hydrogen system, have been reported, but not verified. Hot fusion is understood and may result in large power plants in several decades. “Cold fusion”, now called Low-Energy Nuclear Reactions (LENR), remains a scientific mystery. If adequately funded, LENR could lead to safe, non-radioactive, green, small, distributed nuclear energy sources in less than two or three decades, well before hot fusion can produce commercial power.

In this work, we performed experiments of absorption of hydrogen and deuterium gas by Pd thin films, and we compared the behavior of these samples to unprocessed films. We also employed a continuous wave He–Ne laser to irradiate the samples inside the chamber during the treatment, in order to increase the gas absorption. Using a scanning electron microscope (SEM) and an electron probe micro-analyzer (EDX), we observed structures like spots on the surface of the treated samples. Inside the spots, elements other than Pd were found. Based on these results, we determined that gas loading is an effective way to transmute elements, and the laser action has been a very effective way to increase morphological changes in the treated samples.
Issues Related to Reproducibility in a CMNS Experiment

Unexplained emission of charged nuclear projectiles due to electrolysis has been reported by Richard Oriani. Experimental results were said to be highly reproducible. Working independently, we were not able to observe emission of charged nuclear particles (in a chemical process similar to Oriani’s) and therefore are unable to provide supporting evidence that the effect is reproducible.
