House of Dieulafait (Paris, 1851–1898)
Authors: Faryś Przemysław Krystian
Published: January 2025

The article focuses on the history of the now almost completely forgotten Dieulafait fashion house existing in Paris at 1. Boulevard de la Madeleine in the second half of the 19th century. The examples of clothing of this Parisian brand, preserved very sparingly in museums and private collections, do not help in deep research. However, they are still very interesting testimonies to the existence of this clothing company and the fashion trends of its times. The analysis of several preserved notarial documents documenting the company’s development cycles and advertisements and press articles about the Dieulafait brand, present a very interesting picture of the development of this company. From a small fur workshop offering also leather goods, to a famous fashion house offering exclusive furs and other outerwear, ready-made clothing and dresses. The history of the company’s development is interesting and reflects the history of European fashion, the production of custom-made clothing and ready-made clothing in the second half of the 19th century. Maison Dieulafait was a part of 19th-century, cosmopolitan Paris, so its history reflects the progress of consumerism and capitalism which shaped the production and trade of exclusive goods. The history of Maison Dieulafait also shows the complexity of the economic and marketing processes that have taken place to maintain and develop this brand for five decades.

Authors: Dewi Arie Setya , Nugrahani Henny Saptatia Drajati
Published: January 2025

This study aims to analyze the importance of the EU’s Bill on Cyber Solidarity Act (bill) in order to strengthen the EU’s cyber resilience by enhancing preparedness and achieving equal capacities of EU member states in dealing with significant and large-scale cyber incidents. The cross-border nature of cybersecurity incidents can be too disruptive for a single or some affected member states to tackle on its own, necessitating collective action at the EU level. This study applied the qualitative method with library research using secondary data sourced from scientific journals and official documents. The authors used English school theory through the lens of the concept of solidarity. The result of this study reveals the important role of the bill in the EU in reinforcing cooperation among member states and EU institutions, thereby making the region fully prepared and more responsive to cybersecurity incidents. The main finding of this study is that the bill will become a legal umbrella for both member states and EU institutions to be able to implement the pre-incident, during-incident, and post-incident actions in a more coordinated manner thus, it will enhance the EU's overall capacities to deal with cybersecurity incidents.
Ontological Security of Poland’s Resistance to the European Relocation and Resettlement Scheme
Authors: Divacitra Anggita , Suharman Yoga
Published: January 2025

This article analyses Poland's foreign policy in resisting the European Union (EU) relocation and resettlement schemes from an ontological security perspective. The two aspects of ontological security theory utilized in this article, namely state biographical narratives and discursive strategies, and how these affect the changing pattern of Poland’s foreign policy behavior. The discourse analysis method was employed to interpret narratives developed in society and the ruling power. The results show that Poland's rejection is shaped through narratives propagated as an effort to defend the continuity of authenticity of Poland’s identity as a protector of traditional values, which are rooted in its socio-historical structures and collective memory of nations. Additionally, discursive strategies reveal that Poland has acted as a positive subject rather than an ‘other.’ The article aims to contribute to the development of ontological security studies related to how non-material factors underpin foreign policy behavior.
Role of Insurance Relation Doctors in Reducing the Waiting Time for Inpatient Discharge: An Observational Study
Authors: Bernadette Jesslyn , Bashabih Masyitoh
Published: January 2025

Waiting time for patient discharge is a key indicator in determining the quality of hospital services. In an effort to improve waiting time for patient discharge, some hospitals recruit insurance relation doctors to help check discharge paperwork, especially for patients with insurance coverage. This study aims to see the role of insurance relation doctors in reducing the waiting time for inpatient discharge. This study is an observational study with a cross-sectional study design. Waiting time data was taken through the hospital system and analyzed univariately and bivariately using the independent t-statistical test. Univariate data showed a decrease in the waiting time for inpatient discharge by 5% after the insurance relation doctor joined. However, the statistical test results showed that there was no significant relationship (CI 95% p>0.05) between the joining of insurance relation doctors and the decrease in the waiting time for inpatient discharge. The role of insurance relations doctors has yet to have a significant effect in reducing waiting time for discharge, possibly due to the short duration of the intervention, the involvement of many parties, and the workload of insurance relations doctors. Further research is needed regarding the details of the inpatient discharge process and the productivity of insurance relations doctors in carrying out their roles in the hospital.
Implementation of ANOVA and Regression to Optimize Vibratory Stress Relief Parameters in EN 31 Steel to Reduce Residual Stress and Improve Brinell Hardness
Authors: Bhokare Pankaj , Vasistha Vishal
Published: January 2025

This study examines the impact of Vibratory Stress Relief (VSR) on the stabilization of the Brinell hardness and the reduction of residual stresses in EN 31 steel components. EN 31, renowned for its high hardness and wear resistance, is prone to residual stress accumulation during forceful turning, compromising dimensional stability and fatigue life. To address this, the influence of critical VSR parameters—vibration frequency, amplitude, and treatment time—was analyzed. Regression models and ANOVA results confirmed that VSR effectively reduces residual stress, with the pre-VSR residual stress (BSR) model achieving an R² of 91.31% and the post-VSR residual stress (ASR) model achieving 92.61%. The negative coefficient for amplitude in the ASR model highlighted its substantial effect on stress reduction. Brinell hardness improved significantly after VSR, with the pre-VSR hardness (BBH) model showing an R² of 99.76% and the post-VSR hardness (ABH) model achieving 93.75%. The research affirms that the optimization of VSR parameters, specifically amplitude and frequency, improves mechanical stability and guarantees consistent performance in precision manufacturing applications.
Major Findings: The major finding was that optimized VSR parameters significantly reduce residual stresses and improve Brinell hardness in EN 31 steel, achieving up to 92.61% accuracy in stress prediction and 93.75% accuracy in hardness improvement.

Published: January 2025

The Majalaya weaving, which is made manually by non-machine weaving tools / Alat Tenun Bukan Mesin (ATBM), became a record of history, culture, art and technology which is embodied through motifs and colors. In the early 1920s, the Majalaya weaving industry was pioneered by three women from Majalaya. However, due to various factors, from interviews that have been conducted with community leaders in Majalaya, as well as observations in the field, there are apparently not yet a media being available that can capture the history of women pioneers and the history of Majalaya weaving and transfer this knowledge to children. Thus, this research is aimed at creating a suitable medium that can preserve the memory of women pioneers and the history of Majalaya weaving. Using a participatory approach carried out by searching the historical data, as well as interviews with community leaders who are also descendants of the pioneers, this research develops several visual storytelling potentials initiated by character design for children’s picture books.

About the influence of the natural anthocyanin delphinidin on the lifespan of Drosophila melanogaster
Authors: Platonova E. , Golubev D. , Patov S. , Nekrasova P. , Shaposhnikov M. , Moskalev A.
Published: January 2025

Anthocyanins are vividly colored pigments that appear pink, red, blue, or violet and are dissolved in the vacuolar sap of the epidermal tissues of flowers, fruits, leaves, and stems. Delphinidin is one of the most common anthocyanins with the heroprotective potential. In this study, we examined the effect of delphinidin on the lifespan of both male and female Drosophila melanogaster. Our results showed that delphinidin concentration of 10 µM causes a statistically significant decrease in the median lifespan of male Drosophila melanogaster by 5% and an increase in median lifespan of females by 4 %. However, the mechanism of action of delphinidin on the organism is still understudied that limits our understanding of its heroprotective properties. In this context, studying the effects of delphinidin on the stress resistance, viability indicators, and the expression levels of aging-related genes in Drosophila melanogaster appears to be a promising direction. Such studies would discover the mechanisms of heroprotection and aging, as well as answer the question how natural anthocyanins like delphinidin can be used to improve human health and enlarge lifespan.

Published: January 2025

Media usage for Black Soldier Flies Larvae (BSFL) growth has not been standardized yet, and many research has tried to elucidate different substrates to produce optimal BSFL growth. This study aimed to analyse the effect of different media with different metabolizable energy and nutrient content, such as tofu waste (high metabolizable energy), Azolla microphylla (moderate metabolizable energy), and layer manure (low metabolizable energy), on the yield and nutritional properties of 19-d-old Black Soldier Fly Larvae (BSFL). We grew BSFL from egg to 19-d-old larvae and analysed the BSFL yields by total and individual weight. Nutritional properties were analysed by using proximate, including water content, ash, crude protein, crude fiber, and crude fat. The results showed that the growth media of BSFL on tofu waste, Azolla microphylla, and layer manure showed significant differences in total weight and individual weight (p<0.05). Tofu waste produced the highest total weight (280,75±4,99 g). The nutrient content (water, ash, crude protein, crude fat, and crude fiber) of BSFL grown on tofu waste is the best for yield production. Tofu waste also showed excellent performance in nutrient content except for the percentage of protein compared to Azolla, which was the highest among media, and tofu waste as a growth media for BSFL produced lower protein content. The fiber content of media might influence the protein content. In conclusion, we suggest using high metabolizable energy for BSFL growth media to obtain good yield and high nutrient properties.

Authors: Hanim Chusnul , Hanif Muhammad Fathin , Agus Ali
Published: January 2025

Iron's significance in human health and diseases has been extensively examined in recent reviews, leading to the consensus that iron insufficiency is a worldwide issue requiring immediate attention. Fe-enriched eggs are significant for delivering this essential trace mineral to humans. This study aimed to assess the effects of adding premix minerals on the physical and chemical quality of eggs and the yolk's iron levels. 1,680 Lohman brown laying hens, aged 31 weeks (body weight: 1.70±0.11 kg, egg production average: 81.2 %), were divided into two groups (n = 840) and fed different diets for six weeks. The diets included a basal diet (CON) and a diet enriched with a 2.5 g / kg food premix mineral (PM-Fe). The findings indicated that there was no impact on the physical and chemical quality of the eggs. However, compared to the control diet, the addition of premix significantly enhanced the iron level in the yolk after 42 days (p<0.05). To summarize, adding 2.5 g per kg of premix mineral (which contains 12.6 g per kg of iron premix) can result in a 23.4% rise in iron content in the diet and a 15.7% increase in iron content in the egg yolk.

This study aimed to determine the effect of L-isoleucine supplementation in the diet on the growth performance of Kampong chickens at the starter phase (1-6 weeks). This study was conducted at Kefamenanu, East Nusa Tenggara Province, Indonesia, from May to June 2023. A total of two hundred and fifty-week-old Kampong chickens with an average initial weight of 59.03±0.52 g were used in the study. The chickens were divided into five treatments with five replications based on a completely randomized design. The diet treatments were: T0 (control feed); T1 (T0 + 0.20% L-isoleucine, NRC, 1994 for broilers); T2 (T0 + 0.30% L-isoleucine); T3 (T0 + 0.40% L-isoleucine); and T4 (T0 + 0.50% L-isoleucine). The parameters observed were body weight, weight gain, feed intake, feed conversion ratio, carcass weight, and carcass percentage. The data obtained were analyzed using variance analysis and the Duncan test. The study result showed that the groups T3 and T2 had the highest body weight (330.76±1.29; 334.48±1.47 g/bird, respectively). The highest weight gain was in group T2 (275.54±1.39 g/bird/5 weeks). Group T3 had the highest feed intake (613.15±5.79 g/bird/5 weeks) and the lowest feed conversion ratio (2.22±0.02). The highest carcass weight was in groups T2 and T3 (189.95±1.17 and 189.32±0.65 g/bird, respectively), while the highest carcass percentage was in group T2 (57.43±0.47 %/bird). The statistical analysis indicated that body weight, weight gain, feed conversion ratio, and carcass weight were affected by the level of L-isoleucine (p<0.05). In contrast, feed intake and carcass percentage were not significant. It was concluded that supplementation with 0.40% L-isoleucine to the diet of Kampong chicken resulted in optimal growth performance at the starter phase (1-6 weeks).

This study aimed to examine the effect of marlin fish (Istiompax indica) byproduct meal (MFBM) mixed with some other feed ingredients such as yellow corn (YC), rice bran (RB), broken rice (BR), and top mix (TM) as a mixture feed (MF) in replacement fractionally a commercial ration (CR) on carcasses and organs of broiler chickens. As a comparison,  commercial local fish meal (CLFM) was used instead of MFBM in the MF. A total of 100 DOCs, strain MB 202, were raised for 35 days of age to feed the experimental rations. The experimental rations were: CR= 100% CP511/512 (control), MFBM4= 80% CP511/512 + 20% MF1 containing 4% MFBM, MFBM8= 80% CP511/512 + 20% MF2 containing 8% MFBM, CLFM4= 80% CP511/512 + 20% MF3 containing 4% CLFM, and CLFM8= 80% CP511/512 + 20% MF4 containing 8% CLFM. The research used a completely randomized design (CRD) with five treatments, four replications, and two subsamples. Data were analyzed by Analysis of Variance (ANOVA) and continued by Duncan’s multiple range taste (DMRT) only if the results detected a significant difference. This study showed that at 4% usage within the MF, using MFBM did not indicate a significant difference in the whole carcass and cuts-up weights than using CLFM. However, at the level of 8% within an MF, the former was significantly higher (p<0.05) on the whole carcass and breast weight than the latter. In conclusion, marlin fish byproduct meal (MFBM) could be used up to 8% to produce better whole carcass and breast weight compared to commercial local fish meal (CLFM) without adverse effects on the internal organs of broilers.

Farmers in Indonesia utilize a substantial amount of rice straw to provide feed for their livestock but restricted in terms of its low nutritional value. This study was conducted with objective to evaluate the quality of rice straw silage with addition of sacha inchi (Plukenetia volubilis L.) meal and sambung nyawa (Gynura procumbens) leaves based on physical, chemical, and microbiological properties. The study employed a completely randomized design with 9 treatments (P0: 100% rice straw, P1: 90% rice straw + 10% sacha inchi meal, P2: 85% rice straw + 15% sacha inchi meal, P3: 80% rice straw + 20% sacha inchi meal, P4: 75% rice straw + 25% sacha inchi meal, P5: P1+10% sambung nyawa leaves, P6: P2+10% sambung nyawa leaves, P7: P3+10% sambung nyawa leaves, P8: P4+10% sambung nyawa leaves) and 5 replications, incorporating the addition of sambung nyawa leaves. The variables examined include the physical quality i.e. colour, flavour, texture, and presence of mold; chemical quality i.e. pH, crude protein (CP), and crude fibre (CF); and microbiological quality i.e. lactic acid bacteria (LAB), yeasts, aerobic bacteria, and pathogenic bacteria. The results of the physical quality test indicated that the addition of sacha inchi meal and sambung nyawa leaves resulted no significant difference. On the other hand, the chemical quality showed that the addition of sacha inchi meal and sambung nyawa leaves have enhanced the rice straw silage nutritional content (p<0.05) particularly CP content by about 4 fold. The microbiological tests showed that the addition of sacha inchi meal and sambung nyawa leaves had an impact on the preservation of silage by inhibiting the growth of pathogenic microorganisms. It is concluded that the quality of rice straw silage has improved by the addition of 10-25% sacha inchi meal and 10% sambung nyawa leaves

Published: January 2025

Polyunsaturated fatty acids (PUFA) supplementation in animal feed is expected to increase unsaturated fatty acids content in livestock products. Lemuru fish oil supplementation as a source of PUFA can function as a hydrogen sink to reduce methane production. The contribution of methane gas emissions in livestock reaches 15-17% of the world's methane gas emissions. Encapsulation of PUFA using natural ingredients of cinamaldehyde is expected to be a solution to increasing PUFA in livestock product and improving environmentally friendly animal husbandry. This study aimed to determine the effect of using cinnamaldehyde as an encapsulation agent for lemuru fish oil as a source of PUFA on in vitro gas, methane and CO2 productions. Treatments consisted of different levels of cinnamaldehyde, namely 0, 250, 500, 750 and 1000 (mg/kg feed DM), with the 5% lemuru oil as PUFA source. The experimental design used a one-way ANOVA in completely randomized design pattern consisting of five treatments and three replicates. Each replicate was duplicate, and then, if there were significant differences, it was continued with Duncan's New Multiple Range Test (DMRT) with SPSS version 23. This study discovered that the use of cinnamaldehyde did not affect the in vitro kinetics of gas and CO2 production. The use of cinnamaldehyde level of 500 mg/kg DM feed is the optimal level that can be used as an encapsulation agent for lemuru oil without causing an increase in methane production.

Published: January 2025

Gamma-ray irradiation can induce plant mutations, resulting in stable genetic changes that persist in future generations. This study aims to assess the morphological characteristics of the potential mutant of Hedge Lucerne (Desmanthus virgatus) that has developed adaptation to high salinity conditions as a result of irradiation using gamma-ray. A total of 36 candidate mutants first generation (M1) of D. virgatus were used in this study, and they had developed adaptation to high salinity conditions (8.4 dS/m) and were observed 64 wk after planting. The collected data underwent a descriptive statistical analysis and succeeded by applying the Shapiro-Wilk test to assess the normality of the data distribution. A concentration index greater than one (>1.00) signifies a high value of the plant’s morphological characteristic. All levels of gamma irradiation groups produced an excellent survival response in the mutant candidate. The high diversity in morphological characteristics was reflected in the number of compound leaves, the width of compound leaves, and the number of leaves per pinnae, flowers, and pods. The dominant color of the lower leaves was 7.5 Green Yellow (5/6), and the middle leaves were 7.5 Green Yellow (5/6), while the dominant color of the upper leaves was 7.5 Green Yellow (6/8). The mutant candidate of D. virgatus exhibited the best characteristics, as determined by the concentration index, were those subjected to 200 Gray and 300 Gray irradiation. Fifteen superior mutant candidates were identified, namely GDV100.1, GDV100.2, GDV100.4, GDV100.5, GDV200.2, GDV200.3, GDV200.7, GDV200.9, GDV200.10, GDV300.3, GDV300.4, GDV300.5, GDV300.12, GDV300.13. and GDV 500.1. The three best mutant candidates (M1) were GDV100.2, GDV200.3, and GDV500.1. The three best mutant candidates (M1) were GDV100.2, GDV200.3, and GDV500.1.

The main structural elements of melts of foundry aluminum‑copper‑silicon alloys are elementary nanocrystals of aluminum, copper, silicon and their free atoms. The main crystallizing phases of these alloys are microcrystals of α‑phases, silicon and θ‑phases. The process of their crystallization is nanostructural. First, structure‑forming nanocrystals are formed from elementary nanocrystals and free atoms. Then the centers of crystallization of microcrystals of phases are formed from them. From them, the structure‑forming nanocrystals of m free atoms of aluminum, copper, and silicon, microcrystals of α‑phases, silicon, and θ‑phases are formed. It is shown that the structural stability during remelting of cast aluminum‑copper‑silicon alloys is inversely proportional to the concentrations of adsorbed hydrogen and oxygen atoms.

Currently, the processes of applying protective coatings to the surface of steel products are widely used – bronzing, latuning, etc. These operations are performed by thermocatalytically applying lead compounds to the surface of steel products, followed by reliable fixation of a layer of bronze, brass, etc. on this substrate. Taking into account subsequent technological operations, a significant amount of circulating, washing and wastewater containing a sufficiently large number of dissolved compounds is formed.

One of the key quality indicators for coiled steel products, which is standardized and monitored during certification, is the depth of the decarburized layer on the surface. This layer forms during both rolling and heat treatment. Decarburization and scale formation significantly reduce the mechanical properties of the surface layers of steel products, making the surface more susceptible to scratches, scoring, and other defects during rolling, calibration, and cold heading. The formation of a decarburized layer necessitates additional machining costs, leading to increased metal waste and the disposal of a considerable amount of steel.

This article presents an experimental study aimed at identifying one of the causes of localized decarburization in 20G2R steel wire rod after annealing.
Heat treatment technology for improving wear resistance of high‑precision die tools
Authors: Berdiev D. M.
Published: January 2025

A heat treatment process involving hardening with intermediate tempering has been developed to enhance the wear resistance of high‑precision die tools by 1.5–2 times compared to standard heat treatments. When heating for hardening above 1150 °C, secondary carbides dissolve intensively, austenite grain growth occurs, and there is a marked increase in retained austenite. The most suitable approach proved to be intermediate tempering at 600 °C, which avoids significant austenite grain growth with increasing initial hardening temperature, resulting in a fine to medium needle‑like martensitic structure with some residual austenite.

The influence of modes of preliminary heat treatment (HT) of P91 steel on crack formation during impact bending test has been investigated. Curves of dependence of force variation in time and specimen deflection variation depending on the force have been experimentally obtained, by which the following were determined: crack nucleation energy, crack development energy, maximum value of specimen deflection before fracture, maximum force and fracture force, strain rate, time before fracture, amount of fibrous component, impact toughness, stress intensity coefficient. The fractures were investigated by optical microscopy methods. It is shown that standard pre‑welding heat treatment (HT) of P91 steel – double normalization significantly reduces impact toughness, transforming the fracture into a quasi‑brittle state. The use of different variants of thermocyclic treatment (TCT) increases the total fracture energy and minimizes the amount of brittle component, while after TCT the fracture has mainly intracrystalline character.

The article presents sources of sulfur and phosphorus entering the weld pool, their influence on the quality of weld metal during electric arc welding and methods of their removal. It is shown that the influence of sulfur and phosphorus on the formation of hot cracks is mutually enhanced by the fact that the liquation sites of the compounds of these elements in the weld metal coincide. Sulfur removal is facilitated by Mn introduced into the weld pool melt and the main oxides of manganese and calcium contained in the slag, and phosphorus removal is facilitated by the main oxides of FeO and CaO contained in the slag.

Authors:   , Carbajal Barrios Miguel Alfonso , Cruz Vargas Johanna
Published: January 2025

Introducción: La popularidad de la lipoescultura ha aumentado debido a su alto índice de satisfacción y bajo número de complicaciones. Sin embargo, en América Latina se han reportado complicaciones graves debido a diversos factores, como eliminación excesiva de grasa, pacientes obesos y múltiples procedimientos al mismo tiempo. Por lo tanto, nuestro objetivo fue determinar la asociación entre un índice de masa corporal (IMC) >30 kg/m2 con el desarrollo de complicaciones postoperatorias en pacientes sometidos a lipoescultura. Materiales y métodos: Se realizó un estudio de cohorte retrospectivo en pacientes sometidos a lipoescultura en la Clínica “Nova Quirúrgica” de Arequipa entre 2020-2021. La asociación de las variables con el desarrollo de complicaciones se determinó mediante análisis de regresión logística. Resultados: Se identificaron un total de 231 pacientes. La mediana de edad fue 35 años, la mayoría eran mujeres (97,4%). Se identificaron un total de 25,6% de pacientes con IMC ≥30kg/m2. El 13,4% desarrolló complicaciones postoperatorias, la mayoría fueron seromas (10,8%), seguido de infecciones de sitio superficial (2,6%), hematomas (1,7%) y trombosis venosa profunda (0,4%). No se identificaron otras complicaciones. En el análisis multivariado, los factores de riesgo independientes para el desarrollo de complicaciones fueron un IMC>30kg/m2 (RR=1,04, IC95%:1,27-10,32, p=0,016) y mayor tiempo operatorio (RR=3,63, IC: 95% : 1,00-1,02, p=0,001), y mayor volumen de grasa eliminada (RR=1,01, IC 95%:1,01-1,01, p=0,002). Conclusiones: Los pacientes sometidos a lipoescultura con un IMC > 30 kg/m2 tienen aproximadamente 3,5 veces mayor riesgo de desarrollar complicaciones posquirúrgicas en comparación con los pacientes no obesos. Otros factores de riesgo fueron un tiempo operatorio más prolongado y un mayor volumen de grasa extraída.

Introducción: La pandemia por COVID-19 impactó negativamente en la salud mental de la población a nivel mundial y aumentó la manifestación de rasgos de mala adaptación. Estos han generado grados de disfunción emocional. Actualmente, la prevalencia de adicción a internet generalizada también se ha visto incrementado con algunos autores implicando medidas como la cuarentena y el distanciamiento social. Además, se han realizado estudios que asocian los rasgos de personalidad con la adicción a internet generalizada (AGI). Métodos: Este estudio observacional, analítico, transversal en estudiantes de la universidad Científica del Sur de 18 - 25 años asocio los rasgos de personalidad y la AGI mediante el programa estadístico “Stata versión 16” utilizando data proveniente de encuestas electrónicas. Se crearon modelos lineales generalizados con familia Poisson permitiendo calcular las razones de prevalencia crudas y ajustadas, mediante modelos bivariables y multivariables (ajustando por sexo). Resultados: Los rasgos de personalidad y la adicción generalizada al internet están significativamente asociados (p<0.001) Además, se determinó un riesgo aumentado de 1.32 veces (mediante la razón de prevalencia) para afecto negativo, 2.43 para desapego, 2.59 para antagonismo, 2.68 para desinhibición y 1.56 para psicoticismo. Conclusiones: Hemos observado asociaciones significativas entre todos los rasgos de mal adaptación y la AGI siendo de particular interés la desinhibición que contribuía al mayor aumento de riesgo para el desarrollo de AGI (2.68 veces más). Además, se observó una tendencia mayor en la población masculina (con P<0.001).

Tumors of unknown origin (TUO) generally result in poor patient survival and are clinically difficult to address. Identification of the site of origin in TUO patients is paramount to their improved treatment and survival but is difficult to obtain with current methods. Here, we develop a random forest machine learning TUO methylation classifier using a large number of primary and metastatic tumor samples. Our classifier achieves high accuracy in primary site identification when applied to both publicly available and internal validation samples, with 97% of samples classified correctly and 85% receiving high probability scores (≥0.9). Moreover, by employing pathologist expertise and t-SNE visualization, the TUO classifier can assign samples to 46 different sites of origin/disease classes. This strategy also revealed multiple classes of yet unknown significance for future exploration. Overall, the presented TUO classifier represents a significant step forward in the diagnosis of TUO tumors.

Medical applications require materials with a high X-ray capture cross-section to reduce the radiation dose to the human body. Hybrid organo-inorganic perovskites are promising materials for such systems due to the presence of lead ions in their composition. The electrical properties of CH3NH3PbBr3 single crystals synthesized by the method of modified crystallization with inverse temperature dependence are studied. The conducted studies of the electrical properties allowed us to establish the applicability of the obtained crystals for medical applications and to propose a possible technical solution for the corresponding measuring cell.

Authors: Sharma Rahul , Hanna Angelica , Sriranganat Aswen , Kertes Peter , Yau Gary
Published: January 2025

Objectives
To explore the evidence on the use of anti-vascular endothelial growth factor (anti-VEGF) therapy for the treatment of peripapillary choroidal neovascular membrane (pCNVM).
Methods
Medline, Embase and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) were searched between January 2000 and December 2024 for relevant articles that used anti-VEGF therapy to treat pCNVM of any origin. This review followed PRISMA guidelines and was prospectively registered (PROSPERO registration number CRD42024551949).
Results
Ten studies reporting on 269 eyes were included. Eight studies used a pro re nata (PRN) strategy, 1 study used a loading phase followed by an as-needed phase and 1 study used a fixed schedule strategy. There was a mean of 7 injections required. Eight studies reported improvements in best corrected visual acuity (BCVA) at final follow-up following treatment. The mean logarithm of the minimum angle of resolution (logMAR) change was 0.092, or approximately one line Snellen improvement. Two studies reported on macular thickness, and one reported on choroidal thickness after treatment, all of which noted decreased thickness at final follow-up. No significant complications were reported.
Conclusions
For patients with pCNVM of various etiologies, anti-VEGF injections using any treatment strategy, including conservative management with a PRN approach, seems to be a safe and effective therapy associated with improved visual acuity.
