Authors: Муминов Ш , Косимова Г
Published: January 2025

Background: The study explores mechanisms of intradialytic hemodynamic instability, which remains a significant challenge in the management of chronic kidney disease patients undergoing hemodialysis. Understanding the factors contributing to this condition is crucial for enhancing patient outcomes.
Objective: To review and analyze the primary pathophysiological mechanisms leading to intradialytic hemodynamic instability.
Material and Methods: The review synthesizes data from recent studies and clinical trials focused on hemodynamic changes during hemodialysis. The analysis includes factors like plasma volume reduction, myocardial contractility, and systemic perfusion.
Results: The main mechanisms of intradialytic hemodynamic instability involve decreased plasma volume, reduced venous return, lower left ventricular preload and contractility, and diminished stroke and minute volumes. Secondary contributing factors include chronotropic insufficiency, pathological myocardial remodeling, and systemic and regional perfusion deficits affecting abdominal, cerebral, and coronary circulation.
Conclusion: Comprehensive understanding of the pathogenesis of intradialytic hemodynamic instability highlights the importance of targeted therapeutic interventions to mitigate cardiovascular risks and improve patient quality of life.

Published: January 2025

Background.Reperfusion therapies, including primary percutaneous coronary intervention (PCI), thrombolysis, and salvage PCI, are crucial for treating patients with ST-segment elevation myocardial infarction (STEMI). Evaluating their effectiveness through myocardial strain provides valuable insights into myocardial recovery.
Materials and methods. A total of 200 STEMI patients underwent reperfusion therapy via primary thrombolysis, primary PCI, or salvage PCI. Myocardial strain was assessed using echocardiography at three stages: before reperfusion, immediately after reperfusion, and six months post-procedure.
Results.Patients treated with primary PCI demonstrated significantly better recovery in myocardial strain compared to those who received thrombolysis or salvage PCI. The six-month follow-up confirmed sustained improvement in myocardial contractility among primary PCI patients.
Conclusion. Primary PCI is the most effective reperfusion method for restoring myocardial function in STEMI patients, as evidenced by superior myocardial strain recovery. Early identification and application of appropriate reperfusion strategies are essential for optimizing patient outcomes.

Competition for Space Drives Morphological Abnormalities in the Epiphytic Foraminifer Vertebralina Striata in Mangles Bay, Western Australia
Authors: Tremblin Clément M. , Parker Justin H. , Haig David W.
Published: January 2025

Aberrant morphologies are common in a foraminiferal assemblage living on the ribbon-like seagrass Posidonia in the shallow waters (<3 m) of Mangles Bay, Cockburn Sound, Western Australia. Vertebralina striata is one of the most conspicuous and abundant foraminifers living in the seagrass meadows. Although abnormal tests occur throughout the year, a sample collected in the Australian Summer contained an unusually high abundance of Vertebralina with deformed tests living amongst the dense tufted brown alga Sphacelaria, epiphytic on mature parts of Posidonia leaves. Many mature specimens of V. striata have deformed final uniserial chambers with earlier trochospiral chambers unaffected. Abnormalities include bifurcation and trifurcation of chambers, as well as cavities and depressions in the walls. These are associated with Sphacelaria thalli which obstruct chamber addition in adult tests by restricting living space. Seasonal growth patterns in both Posidonia and its epiphytic Sphacelaria may result in natural increases in the abundance of abnormal Vertebralina tests in summer.
The Experimental Study of C. Papaya Leaf Extract & Its Effect on the Platelet Count: A Potential Treatment of Dengue Patients
Authors: G. Gardose Rences
Published: January 2025

Plants have a variety of uses, especially in medicinal aspects, they have phytochemicals which have effects on the human body. People in rural areas used the decoction method and mechanical pounding method in preparing the plant extracts. People usually choose not to go to drugstores to purchase drugs, which sometimes is costly. This experimental study aimed to determine the effects of fresh young papaya leaf extracts of different varieties on the platelet count of white mice. In this study, C. papaya, commonly known as the papaya plant, was extracted through a mechanical or pounding method and was force-fed to white mice once every 24 hours for three to six consecutive days. After each treatment, blood specimens were taken, and platelet count was analyzed. Results showed that there was a significant increase in the platelet count of white mice treated with C. papaya extract compared to that of the controlled white mice fed with water. Furthermore, results showed that the affectivity of C. papaya extract is observable after the third day of treatment. It is hermaphroditic and produces high-quality fruits with excellent flavors. The flesh color depends on the strain. Canaries stated that Red Lady papaya is a supreme papaya with bright orange sweet fruits, 1-3 kg each, mostly seedless. Red Lady papaya trees produce fruit on average nine months from seed. It is a hermaphrodite cultivar of average height, tolerant to papaya ring spot virus. Papain is the most abundant and most active. One important fact to take note of is that these two enzymes gradually vanish as the fruit ripens. So, in order to avail the benefits, pick your fruit when it is still green. Apart from aiding the digestion process, other papaya enzyme benefits include treating oedema, inflammation and wounds.

Published: January 2025

El presente artículo revisó la evolución histórica, conceptual y social de la patria potestad en Ecuador, analizando cómo las normas jurídicas y los cambios culturales han impactado en las dinámicas familiares y en el rol parental. Se abordaron temas como las disputas por la custodia de los hijos, los estereotipos de género y la influencia del sistema judicial en la crianza. El objetivo general fue explorar el impacto de las discusiones normativas, experiencias personales y activismo en la transformación de la corresponsabilidad parental en el país. La metodología incluyó un análisis bibliográfico y entrevistas con actores clave, destacando estudios internacionales y locales para contextualizar la situación en Ecuador. Entre los resultados, se observó que los roles tradicionales de género aún dificultaban la participación equitativa de los padres en la crianza, aunque movimientos sociales y legislaciones progresistas han promovido la custodia compartida como una medida que fomenta la igualdad. También se destacó que las nuevas masculinidades contribuyen al cambio cultural hacia una mayor corresponsabilidad parental. Sin embargo, problemas como la alienación parental y la falta de políticas judiciales específicas limitan el involucramiento efectivo de los padres. El estudio concluyó que la corresponsabilidad parental no solo beneficia a los niños, sino que también impulsa la igualdad de género, equilibrando las responsabilidades de cuidado entre hombres y mujeres.

Archiving Our Bodies:

This article analyses artworks by three non-binary or trans masculine artists: Kris Grey, No title (2019), Emmett Ramstad, The good ones (2006), and Marie Ahlberg Andersen, My Dick Clit has many forms (2022). I look at the corporeal traces the artworks display: wound scabs, blood drops, and crotch imprints, and find that they present a proof of trans becoming which, I would like to suggest, counters hegemonic narratives of transition and disturbs the notion of proof in relation to trans life; to highlight instead, the slowness, temporal multiplicity, and volatile uncapturability of trans embodiment. Through the article, I analyze Grey’s, Ramstad’s, and Andersen’s transition documentation as forms of counter-archiving, as well as how they function as t4t archival offerings – an invitation for other trans people to engage with their transition documentation and the potential of shaping their trans becoming through them. Through my personal narratives as refl exive, personal introductions to the analysis, the artworks, as a t4t archive, shed light on the moments and experiences that in small steps gets us, as trans people, closer to the way we want to be seen and feel about ourselves.
”Queerness is unstoppable”
Authors: Minuva Kim S. P.
Published: January 2025

During the 2010s, video game content and subsets of the gaming community have been diverging in polarized directions regarding LGBTQ topics in video game culture. On the basis of these discourses,this study utilizes framing and discourse analysis to examine how video game publications frame LGBTQ topics in gaming. Analyzing 269 articles published between 2002 and 2020, it fi nds that 57,2% of articles utilize framing characterized by egalitarian equality, compared to 0,7% that use traditionalist morality framing, while 36,1% use neutral framing. A majority of articles likewise deploy politically loaded keywords in a sincere manner rather than a veiled manner, in which these words function as stand-ins for conservative views. Further, the study points to conservative discourses like Gamer-Gate affecting the output of articles between 2014 and 2015 and charts the potential construction of a journalistic paradigm in which journalists do not utilize slurs. This paradigm and high levels of egalitarian and neutral framing differ from previous findings regarding framing in game journalism.
“Here Lies the Possibility of Bodies Turning Elemental”:
Authors: Evang Jenny Andrine Madsen
Published: January 2025

This paper explores the (non)representational aesthetics and politics of Serpent Rain, a 2016 Black feminist film inspired by the recovery of a Danish-Norwegian slave ship. Despite ample historical evidence, Scandinavia’s involvement in the transatlantic slave trade remains an underdiscussed topic; when the history is broached at all, it tends to be relegated to a distant ‘dark chapter’ already overcome. I argue that Serpent Rain rejects this binary of erasure vs. contained representation in its treatment of slavery, enacting instead another type of (non)representation that moves beyond “the limits of most available narratives to explain the position of the enslaved” (Hartman and Wilderson 2023, 184). Taking its meandering and associative form from Serpent Rain’s experimental aesthetics, this article draws on Black feminist theory—particularly Christina Sharpe’s In the Wake—to argue that the film unsettles visual and ontological certainty to dramatize the repetitive structure of racial capitalism and its ongoing reiterative violence, from the sunken slave ship to the ongoing extraction of oil on indigenous land. Ultimately, the film makes us question not only the hegemonic mediation of the enslaved, but also the orthography of the (white) Human and the seeming serenity of Norwegian oceanic landscapes.

The paper highlights the issues of the development of salt therapy, provides an overview of the results of microbiological and sanitary-hygienic studies conducted in situ in surface salt facilities (NSS) of the Perm Territory, as well as in vitro studies of the survival of bacteria of the genus Staphylococcus in modeling the enclosing surfaces of structures for salt therapy. A comparative analysis of the main hygienic parameters of salt facilities revealed differences between silvinite and halite chambers, showedthe dependence of the intensity of therapeutic factors of the internal environment on the service life and compliance with sanitary and hygienic measures. The diversity of microbial communities of terrestrial salt facilities has been studied by gas chromatography-mass spectrometry. The dominant representation of Actinomyces living on salt abiotic surfaces of the NSS suggests that they are a pool of cells that "preserve" other bacteria in a viable state in a highly mineralized environment. The revealed quantitativeand qualitative indicators of the microbiota of salt facilities complement the understanding of the structure of microbial communities under conditions of high salt load and anthropogenic influence, including the distribution of microorganisms – the presence of distinctive groups consisting of permanent and transient ecosystem participants. The study of the biological properties of staphylococci isolated from NSS revealed a high percentage of macrolide-resistant strains and hemolytic cultures, which indicates their anthropogenic origin. The high tolerance of crops to sodium and potassium salts, as well as to heavy metal salts, has been shown to differ among representatives of different species and macrolide-sensitive/resistant crops. The manifestation of the differential sensitivity of staphylococci to the studied factors may provide additional information necessary to assess the ecological potential of these bacteria, their spread and solve the problem of combating staphylococcal infections. The obtained data on the survival of bacteria on salt surfaces of various types, their resistance to high concentrations of salts raises the question of specialmethods of processing fences of structures for salt therapy.

Hybrid powder materials (HPs) of the AgI-SiO2 (AgI-MCM41), where SiO2 is mesoporous mesophase silicon dioxide MСM41, were synthesized using the method of hydrothermal template cocondensation (HTS method). The HPs have a high potential of application in artificial precipitation technologies. The correlation between the concentration of silicon dioxide and silver iodide precursors and morphological, structural and textural, rheological characteristics of the synthesized AgI-MCM41 HPs was studied. Most attention is paid to the formation of a hexagonal crystal structure (β-form, Iodargyrite) of silver iodide and maintaining maximum development (high values of specific surface area) for the AgI-MCM41 system. The phase state of AgI and MCM41 in the hybrid composition was studied by scanning electron microscopy. The optimal component ratio necessary for the formation ofthe hexagonal structure of silver iodide was estimated. Such parameters as the value of specific surface area, pore volume and pore size were taken into account in the study of surface development. Sorption isotherms are described. Morphological features of the obtained AgI-MCM41 HPs were studied by scanning electron microscopy. A number of rheological parameters (such as volatility, fluidity) for synthesized powders was investigated, which allow predicting their performance properties. The condensation capabilities of the synthesized AgI-MCM41 HPs are described.

Установлены признаки, на основании которых газодинамическое явление, происшедшее на сопряжении вентиляционного штрека № 1 с технологической сбойкой № 4, следует классифицировать по условиям возникновения, протекания и результатам закончившегося процесса разрушения пород кровли как явление комбинированного типа, представляющего собой разрушение пород кровли с последующим развитием выброса соли и газа. Установлены стадии протекания газодинамического явления комбинированного типа под действием приконтактных и очагового скопления свободных газов. На первой стадии под действием приконтактных скоплений свободного газа на контакте пласта В с пластом каменной соли В–Г в породах кровли сопряжения произошло разрушение пород пласта В по механизму разрушения пород кровли, сопровождающегося газовыделением. На второй стадии по такому же механизму произошло разрушение пород пласта каменной соли В–Г. Далее на третьей стадии произошел собственно выброс соли и гази из карналлитового пласта Г по известному механизму послойного отрыва. На четвертой стадии произошло разрушение пласта каменной соли Г–Д под действием давления свободных газов в приконтактном скоплении, приуроченном к контакту пласта каменной соли Г–Д с карналлитовым пластом Д. На основе изучения технической документации, осмотра места, анализа условий возникновения, протекания и результатов закончившегося процесса разрушения пород кровли установлены причины возникновения газодинамического явления комбинированного типа. Выполнены расчеты и дана количественная оценка критической величины давления газа в приконтактных и очаговых скоплениях свободного газа в породах кровли сопряжения, при которых возможно развитие первой, второй, третьей и четвертой стадий явления комбинированного типа. На основании анализа природы, причин, условий проявления и вероятности возникновения газодинамических явлений в виде явлений комбинированного типа для дальнейшего безопасного ведения горных работ на пласте АБ в условиях УстьЯйвинского рудника БКПРУ-3 разработан комплекс мероприятий, включающий предварительную дегазацию пород кровли горных выработок в местах предполагаемой разделки сопряжений (зарубки и вырубки комбайна) шпурами (скважинами) с помощью буровых установок, расположенных на комбайнах или специального бурового оборудования.

Published: January 2025

One of the processed products from Javanese grasshopper (Valanga nigricornis Burm.) flour that is being developed is snack bars. This product was designed to introduce processed Javanese grasshopper flour (JGF) products with high protein content to consumers. However, the shelf life of the grasshopper snack bar and the best type of packaging to store the product are not yet known. This research aimed to determine the shelf life of Javanese grasshopper snack bars packaged in three different types of packaging and to identify the most effective packaging for these products. The three types of packaging chosen were plastic packaging in the form of a standing pouch (SP), aluminium foil packaging without folds (alufo), and aluminium foil packaging with folds (alumina). This research used the accelerated shelf life testing (ASLT) method with the Arrhenius approach. The parameters measured were moisture, fat, and water activity (aw) content during eight measurement periods with three different storage temperatures (20oC, 30oC, 45oC). There were differences in estimated shelf life based on parameters for each type
of packaging. The shelf life of Javanese grasshopper snack bar products based on packaging type and estimation parameters varied from 0.68 months to 14.81 months. The best parameter to estimate shelf life was the fat content in the alufo packaging, which had the highest R2 value from the order 1 equation in the Arrhenius method with a value of R2 0.999. The shelf life of the Javanese grasshopper snack bar product estimated by measuring the fat content parameters on the alufo packaging was 14.81 months if stored at a temperature of around 30oC.

Laser driven electron beam has important application value in the field of space radiation environment simulation. However, due to the shortcomings of poor spectrum tunability and high laser energy of the electron beam generated by laser direct irradiation of high-density solid targets, its wide application is limited. In this work, a scheme is proposed to simulate the orbital electron radiation in near-Earth space by using laser driven dual-plane composite target electron acceleration. It is found that the high-density solid target Ⅱ can provide a large number of low energy electrons, while the vertical plane target Ⅰ located in the front surface of target II can provide a small number of high energy electrons, which makes the electron energy spectrum very close to that of the space radiation environment. In order to evaluate the similarity between the generated energy spectrum and the space radiation spectrum, a method of evaluating the similarity of energy spectra is proposed, which can describe the local similarity and the global similarity of the energy spectra. For vertical plane target Ⅰ with low density, the electron acceleration is dominated by the laser ponderomotive acceleration that generates a half-wavelength oscillation. As the density increases, the electron acceleration gradually transitions from the laser ponderomotive acceleration to the surface ponderomotive acceleration, and the electron beam energy spectrum is modulated effectively. Meanwhile, the electron temperature of the generated electron beam is linearly related to the length and density of the target Ⅰ, and the optimal target parameters are obtained by the Bayesian optimization, and the generated electron beam is much better matched to the space radiation environment. Compared with the scheme of laser driven single-plane target electron acceleration, the proposed scheme has better tunability of energy spectrum and lower requirement of laser intensity. The results provide a theoretical reference for the experimental study of simulating space radiation environments in different orbitals by using laser-driven electron beams.

Introduction: Around 6% of head injuries are compound skull fractures. Not all compound fractures require surgical intervention; however, some fractures pose surgical challenges due to their location and the extension of fracture segments to adjacent dural venous sinuses. Surgical management includes thorough debridement of fractured segments, along with devitalised and contaminated soft tissues, followed by cranioplasty either in the same sitting or as a staged procedure.

Aim: To analyse the results of single-stage titanium mesh reconstruction in the management of compound and comminuted skull fractures.

Materials and Methods: This was a retrospective descriptive study in the Neurosurgery Department at Veer Surendra Medical Sciences and Research (VIMSAR), Burla, Sambalpur, Odisha, India, from January 2018 to June 2023 and consisting of case records of 98 patients with head injuries associated with compound skull fractures who were admitted. All patients underwent debridement followed by an immediate titanium mesh cranioplasty procedure. The standard debridement technique was followed in all cases. Patients were followed for three months after their discharge from the hospital. Clinicoradiological follow-up was conducted, and outcomes in terms of surgical site infection, titanium mesh exposure, and rejection of the prosthesis were evaluated. Data collected from patients were checked, entered, and analysed using Microsoft Excel, and results were described in percentages.

Results: The mean age of the subjects was 28.48±13.79 years. The predominant mechanism of injury was Road Traffic Accident (RTA), affecting 59 (60.2%) patients. The frequency of skull fractures was significantly higher in men 91 (92.8%) patients compared to women 7 (7.2%) patients. The mean Glasgow Coma Scale (GCS) score was 13.35 at admission, while it was 14.90 at discharge. The fracture was located most commonly in the frontal region in 64 patients (65.3%), followed by the parietal region in 23 (23.5%) patients, and mixed fronto/temporo/parietal bone fractures in 11 (11.2%) patients. Approximately 41 (41.9%) patients had paranasal sinus involvement, and 69 (70.4%) patients had associated dural injury. A very low incidence of complications was observed in patients during their hospital stay and three-month follow-up. Only one patient developed a surgical site infection. One patient experienced sinus formation with intermittent discharge and subsequently required removal of the mesh, while two patients had a transient postoperative Cerebrospinal Fluid (CSF) leak. There were no incidences of immediate postoperative seizures.

Conclusion: Simultaneous debridement and mesh reconstruction do not pose an increased risk of infection, contrary to previous beliefs.

Aim: This study aims to evaluate the effect of echo time (TE) variation on MRI image quality, which is measured using Signal to Noise Ratio (SNR) and Contrast to Noise Ratio (CNR). The focus of the study was on lumbar MRI examinations at RSUD Bali Mandara using a Philips 1.5 Tesla MRI machine.
Study Design: This research used an experimental design with a quantitative approach. The study was conducted in the MRI unit at RSUD Bali Mandara from January to October 2024.
Methodology: The study involved 30 patients who underwent lumbar MRI examinations. Four TE variations (80 ms, 90 ms, 100 ms, and 110 ms) were applied to analyze SNR and CNR in corpus, discus, and cerebrospinal fluid (CSF) tissues using the ROI (Region of Interest) method. Data were analyzed using IBM SPSS statistical software to evaluate the effect of TE variations on image quality. The MRI machine used was the Philips Achieva 1.5 Tesla with standard lumbar imaging protocol parameters.
Results: Increasing the TE value significantly decreased SNR and CNR values. A TE of 80 ms provided the highest SNR and CNR values compared to other TE variations. This indicates that shorter TE produces better image quality.
Conclusion: Good MRI image quality is determined by high SNR and CNR values. This study recommends using an 80 ms TE in lumbar MRI imaging protocols to improve the accuracy of clinical interpretations.

Indian farmers face challenges in wheat production due to poor soil nutrients and imbalanced fertilizer use, making zinc-supplemented fertilizers vital for boosting productivity. Wheat (Triticum aestivum L.) is a vital global food crop, rich in carbohydrates, protein, and essential nutrients, with India being a major producer, although many regions face significant zinc deficiency in their soils. A field study was conducted during Rabi 2021-2022 at Wheat Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The experimental soil collected from the wheat research unit field was slightly alkaline in reaction, medium in organic carbon, moderately calcareous, low in available N, medium in available P, remarkably high in available K, marginal in available S, and sufficient in micronutrients but deficient in Zn. The nine treatments T1 to T9 are applied in the plots in Randomized Block Design with three replications.
The higher nutrient content and N, P, K, S, Zn, Fe, Cu, and Mn uptake was recorded with the soil application of RDF + soil application of ZnSO4 @ 30 kg ha-1.
It is concluded that the soil application of ZnSO4 @ 30 kg ha-1 along with a recommended dose of fertilizer (RDF) at the time of sowing recorded the highest nutrient content, nutrient uptake and improvement in soil fertility.

Importance

Tirzepatide is a glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptor agonist used for the treatment of type 2 diabetes. Efficacy and safety of adding tirzepatide vs prandial insulin to treatment in patients with inadequate glycemic control with basal insulin have not been described.

Objective

To assess the efficacy and safety of tirzepatide vs insulin lispro as an adjunctive therapy to insulin glargine.

Design, Setting, and Participants

This open-label, phase 3b clinical trial was conducted at 135 sites in 15 countries (participants enrolled from October 19, 2020, to November 1, 2022) in 1428 adults with type 2 diabetes taking basal insulin.

Interventions

Participants were randomized (in a 1:1:1:3 ratio) to receive once-weekly subcutaneous injections of tirzepatide (5 mg [n = 243], 10 mg [n = 238], or 15 mg [n = 236]) or prandial thrice-daily insulin lispro (n = 708).

Main Outcomes and Measures

Outcomes included noninferiority of tirzepatide (pooled cohort) vs insulin lispro, both in addition to insulin glargine, in HbA1c change from baseline at week 52 (noninferiority margin, 0.3%). Key secondary end points included change in body weight and percentage of participants achieving hemoglobin A1c (HbA1c) target of less than 7.0%.

Results

Among 1428 randomized participants (824 [57.7%] women; mean [SD] age, 58.8 [9.7] years; mean [SD] HbA1c, 8.8% [1.0%]), 1304 (91.3%) completed the trial. At week 52, estimated mean change from baseline in HbA1c with tirzepatide (pooled cohort) was −2.1% vs −1.1% with insulin lispro, resulting in mean HbA1c levels of 6.7% vs 7.7% (estimated treatment difference, −0.98% [95% CI, −1.17% to −0.79%]; P < .001); results met noninferiority criteria and statistical superiority was achieved. Estimated mean change from baseline in body weight was −9.0 kg with tirzepatide and 3.2 kg with insulin lispro (estimated treatment difference, −12.2 kg [95% CI, −13.4 to −10.9]). The percentage of participants reaching HbA1c less than 7.0% was 68% (483 of 716) with tirzepatide and 36% (256 of 708) with insulin lispro (odds ratio, 4.2 [95% CI, 3.2-5.5]). The most common adverse events with tirzepatide were mild to moderate gastrointestinal symptoms (nausea: 14%-26%; diarrhea: 11%-15%; vomiting: 5%-13%). Hypoglycemia event rates (blood glucose level <54 mg/dL or severe hypoglycemia) were 0.4 events per patient-year with tirzepatide (pooled) and 4.4 events per patient-year with insulin lispro.

Conclusions and Relevance

In people with inadequately controlled type 2 diabetes treated with basal insulin, weekly tirzepatide compared with prandial insulin as an additional treatment with insulin glargine demonstrated reductions in HbA1c and body weight with less hypoglycemia.
