BACKGROUND AND OBJECTIVES:
Superficial temporal artery to middle cerebral artery (STA-MCA) bypass is the workhorse for flow augmentation surgery. Although either interrupted or running sutures can be used to complete the anastomosis with high intraoperative patency rates, no previous study in the cranial bypass literature has compared long-term patency and maturity of end-to-side STA-MCA anastomoses. We compared STA-MCA anastomoses performed with running vs interrupted sutures by evaluating bypass flow and anastomotic maturation on follow-up vascular imaging.

METHODS:
Ninety-six STA-MCA anastomoses were performed from 1/2019 to 6/2024. Forty-seven anastomoses (40 patients) with long-term vascular imaging were retrospectively analyzed. All anastomoses were intraoperatively patent on initial revascularization. Patient demographics, clinical course, and imaging were reviewed. All images were reviewed by a neuroradiologist or a cerebrovascular neurosurgeon.

RESULTS:
Twenty-five anastomoses were performed with interrupted sutures and compared with 22 anastomoses performed with running sutures. All patients underwent a preoperative perfusion assessment confirming a significant hypoperfusion state. There were no significant differences between cohorts in demographics, bypass indication, or time to follow-up. Formal digital subtraction angiography was performed for 35 anastomoses (21 interrupted, 14 running). On digital subtraction angiography follow-up, there was no difference in STA caliber between cohorts (P = .204), but there was a difference in anastomotic growth (P = .014), with 5/21 (23.8%) anastomoses stable or enlarged in the interrupted cohort vs 9/14 (64.3%) stable or enlarged in the running cohort. Notably, of the 47 total anastomoses, there was no difference in long-term bypass patency between interrupted and running anastomoses (22/25 (88.0%) vs 22/22 (100.0%), respectively, P = .380).

CONCLUSION:
No significant differences in patency or STA caliber on follow-up imaging were observed between STA-MCA anastomoses performed with interrupted vs running sutures although a difference in anastomotic maturity was observed, with the running suture cohort having a higher proportion of enlarged or stable anastomoses. Further studies are needed for validation.
Intertemporal Pricing with Resellers: An Empirical Study of Product Drops
Authors: Steele Dayton , Emadi Seyed Morteza , Kesavan Saravanan 
Published: December 2024

Product drops occur when a retailer releases a limited-edition product line on a specific date for a short period of time. Due to limited inventory of the product and the short sales horizon, a resale market emerges where products may resell at higher prices once the firm stocks out. The firm faces a central tradeoff: pricing too high may lead to a longer stockout time and future markdowns; pricing too low may lead to transfer of profits to resellers. Any firm in this position may ask, “How do resellers impact my profit?” To answer this question, we build a dynamic structural model that captures customer decisions to consume or strategically resell, as well as the firm’s intertemporal pricing decision in the presence of resellers. We estimate our model using a unique data set from a retailer of baby clothing with weekly product drops, where customers engage in a resale marketplace through Facebook groups. We find resale data collection and analysis is valuable to incorporate into pricing as firm profit increases by 8.8%, and reseller presence reduces firm profit by 5.8% even if resale data are used in pricing. These impacts are magnified by resale market growth, demonstrating that managers need to take action as resale markets gain wider adoption.

The Condition of Alienation and the Transformation of Value into Price in Karl Marx
Authors: Kadri Jude 
Published: December 2024

Abstract
Using the philosophies of Louis Althusser and István Mészáros, this article seeks to interpret Marx’s theory of the transformation of value into price based on a philosophical view that emphasizes both the base/superstructure dialectic (Althusser) and alienation under capitalism (Mészáros). According to the logic of dialectical materialism, the economic base of the capitalist mode of production is determined by a historical dialectic (alienated labor) that produces an unsolvable contradiction with the capitalist imperatives of the superstructure. The alienation of the workers is perpetuated through their active subordination to the ideal and material power of the capitalist superstructure (including its ideal “law of value” which postulates the domination of exchange value over use value). They are led to believe that the profit-embedded prices of the commodities they produce have nothing to do with them. The illusion is that these prices are decided by an abstract “free market.” In reality, the laborers, due to their alienation, contribute directly to the formation of these prices by allowing the capitalists to freely compete with each other by lowering their respective “price of production.” There can be no profitable prices under capitalism without the contradictory condition of alienation perpetuated by the ideal power of the superstructure.

Published: December 2024

Methylene blue is an organic contaminant that is produced by the plastic, textile, and dye industries. Many studies have been undertaken to investigate the cleanup of methylene blue from industrial effluents. SrO nanoparticles are now being utilized to remove methylene blue colours from water. We used a hydrothermal technique to create strontium oxide nanoparticles for photocatalytic MB breakdown under light conditions. To enhance the solar light activity and avoid charge recombination, we employed a hydrothermal technique to add Ni as a dopant in strontium oxide nanoparticles. Strong base NaOH, nickel nitrate, and strontium nitrate were used as precursors. The nanoparticles were crushed into powder and calcined at 450 °C in a muffle furnace to produce SrO and Ni-doped SrO nanoparticles. The nanoparticles were analyzed using several analytical methods to determine their morphological and structural properties. At 309, 312, and 317 nm, UV-Vis spectroscopy showed absorbance values of SrO doped with varied nickel concentrations. The Ni–O stretching peak was identified in the FTIR analysis of strontium oxide nanoparticles at 402 cm-1 and 581 cm-1, whereas the Sr–O bond gave a signal at 854.84 cm-1. SEM images of Ni-doped SrO nanoparticles were created at various magnifications. The nanostrips are hexagonal and cylindrical. Sherrer's equation was used to compute the average crystalline structure, which showed that the diameters of pure and Ni-doped SrO (2 percent, 3 percent, and 4 percent) nanoparticles were 45.54 nm, 36.14 nm, 42.93 nm, and 41.21 nm, respectively. According to the EDX examination, the relative concentration of Ni-doped SrO is about 72 percent Sr and oxygen, with around 1.34 percent Ni. The resulting sample was tested for photocatalytic degradation of organic pollutants in aqueous solution, such as methylene blue, and the completion of the reaction was monitored using UV-visible spectroscopy to measure the % photocatalytic degradation during light illumination. According to the UV-visible spectra, 90% of the dye was effectively destroyed.

Coagulation factor II thrombin receptor as a promising biomarker in breast cancer management
Authors: Dong Yan-Ming , Bao Guo-Qiang 
Published: December 2024

Abstract
This study aims to comprehensively investigate the role of coagulation factor II thrombin receptor (F2R) in breast cancer (BC) and to evaluate its potential as a biomarker in this context. Data on female BC were retrieved from the TCGA database. Comparative analyses were performed, including enrichment analysis, tumor immune microenvironment analysis, drug sensitivity testing, molecular docking, and cell-based experiments, to assess the expression and function of F2R in BC. Statistical analyses and graphical representations were conducted using R software. The study confirmed a significant upregulation of F2R in BC, which was associated with a more favorable prognosis. Clinical correlation analysis revealed a strong association between F2R expression and key clinical parameters, such as estrogen receptor and progesterone receptor status. Additionally, genes co-expressed with F2R were significantly linked to various biological processes, including cell cycle regulation, oxidative phosphorylation, ribosomal function, and extracellular matrix interactions. F2R also showed associations with immune modulators, particularly CD200 and NRP1. Drug sensitivity analysis, molecular docking, and cell experiments consistently demonstrated positive correlations between F2R expression and sensitivity to dasatinib. This study underscores the potential of F2R as a valuable biomarker in BC, providing insights into the molecular mechanisms underlying tumorigenesis.
Detection and tracking of safety helmet wearing based on deep learning
Authors: Liang Hua , Yang Liqin , Chen Jinhua , Liu Xin , Hang Guihua 
Published: December 2024

Abstract
Failure to wear a helmet correctly is a significant cause of injury or death in the construction industry and industrial production. Traditional supervision methods predominantly rely on manual oversight, incurring substantial costs and demonstrating inefficiencies. To address this pressing issue, the present work introduces an advanced intelligent detection technology based on deep learning algorithms, which leverages the YOLOv5 algorithm to train a dataset, enabling real-time assessment of correct helmet usage among personnel while promptly issuing warnings when deviations are detected. Simultaneously, to mitigate challenges related to object leakage and false detections in complex backgrounds, the model’s performance is further enhanced by optimizing Generalized Intersection over Union, Distance Intersection over Union, and Complete Intersection over Union loss functions and improving the Mosaic-9 data enhancement algorithm. Empirical results validate the system’s efficacy, with the optimized YOLOv5 algorithm achieving an impressive precision rate of 93.16% and a robust recall rate of 88.96%. These findings underscore the system’s ability to accurately identify instances of workers’ improper helmet usage. This enhanced YOLOv5-based intelligent detection technology provides a more efficient and accurate method for monitoring helmet compliance within the construction industry and industrial production, effectively addressing the limitations of traditional manual supervision and ensuring precision in complex operational contexts.
Re-evaluating Cambaztepe in the Context of its Yamnaya (Pit-Grave) Origin, the Anatolian Trade Network and Possible Early Migrations towards Anatolia in the 3rd Millennium BC
Authors: Sezer Okan 
Published: December 2024

Abstract
This study aims to re-evaluate Cambaztepe, located approximately 12 km west of the Silivri district center of İstanbul, where rescue excavations led by the İstanbul Archaeology Museums in 2015 were carried out. Cambaztepe is a burial mound dated to the Early Bronze Age II (EBA II) within Anatolian chronology. It also has a secondary burial context dated to the Iron Age. Although there is no absolute dating, Cambaztepe is currently believed to be the earliest burial mound in Türkiye’s European territory (also known as Eastern Thrace), considering the burial position and the grave goods and/or finds. The excavation team has published only a preliminary report and two papers, of which one was published in a popular magazine. The possible relationship between Cambaztepe and Yamnaya (Pit-Grave), and other related cultures was not examined in the preliminary report. Furthermore, the preliminary report provides inaccurate and misleading suggestions about the way the deceased were placed in the grave and the grave finds. In addition to other evidence, the way the deceased were placed in the grave as a semi-supine position indicates that the Cambaztepe EBA II grave context is related to the Pit-Grave or other cultures with Pit-Grave traditions in the Balkans. However, the grave structure in round shape with a floor of stone slabs and the grave finds, consisting of a beaked jug of inland Western Anatolian origin and a dagger of Anatolian origin, make Cambaztepe different from contemporary burial mounds in the Balkans. The existence of a cremation burial is sufficient to make concrete suggestions in the context of possible early migrations from Europe to Anatolia in the 3rd millennium BC, even though the exact nature of these migrations remains unknown, whether they involved the population movement or transfer of ideas-ideology-beliefs (or a combination of both). Likewise, the Cambaztepe EBA II grave context has a potential to define the mechanism of migration from Anatolia to Europe more precisely. The Cambaztepe EBA II grave context should be placed at the date range 2700–2500 BC, based on the burial practice observed in the Balkans and the grave finds of Anatolian origin.
The role of osteoprotegerin (OPG) in exercise-induced skeletal muscle adaptation

Published: December 2024

Abstract

Objectives
The purpose of this narrative review is to offer an updated perspective on the current research on the glycoprotein Osteoprotegerin (OPG), including its potential therapeutic impact and mechanisms of action, and interaction with bone and muscle tissues.

Content
As health and social care advances people are living longer, with projections suggesting that in 2050 there will be 2 billion people who are aged over 60 years. Yet musculoskeletal health still declines into older age and as a result there is an increase in the proportion of older populations that spend more time with persistent disabilities. Although physical exercise is repeatedly demonstrated to minimise detrimental effects of ageing, it is not always a feasible intervention, and other directions must be considered.

Summary and outlook
OPG, a glycoprotein decoy receptor for the receptor activator of nuclear factor kappa-β ligand (RANKL) is a key regulator of bone formation yet emerging evidence has presented its potential to offer positive outcomes in regard to the preservation of skeletal muscle mass and function. Animal models have shown that OPG levels increase during exercise, and independently acts to restore losses of muscle strength and reduce bone resorption. Interventions to increase circulating OPG alongside exercise may act as a therapeutic target to combat the decline in quality of life in older age in humans. Further research is needed on the mechanisms of its action and interaction in humans in combination with exercise.
Educação e ethos democrático: o desafio da formação para a autonomia
Authors: Ferreira Evandson Paiva 
Published: December 2024

Neste artigo discuto, a partir da obra do filósofo Castoriadis, o modo como a escola é concebida na Modernidade, considerando-se a noção da formação para a cidadania e como o significado de cidadania e de autonomia ganham outro sentido, à medida que a instituição escolar vai sendo dominada pela lógica da vida empresarial. A escola, instituição que participa das duas significações imaginárias modernas, autonomia e controle, também participa do processo de privatização do indivíduo e do eclipse do projeto de autonomia. Cada vez mais submetida aos valores do controle, da normatização, da produtividade, do sucesso individual, da meritocracia, do quantificável, encarna e reforça um novo tipo de heteronomia disfarçado em democracia e autonomia. Discutiremos também essa banalização da educação, a maneira como a escola torna-se cada vez mais distante de um ideal de formação de subjetividades reflexivas e deliberantes, e mais comprometida com a formação de recursos humanos.

Published: December 2024

ABSTRACT

Trial Design:
This controlled in vivo experimental study examines the impact of two periosteum preparation techniques on microcirculation during bone augmentation with isogenic bone grafts in rats.

Methods:
Twenty female Lewis rats were divided into two groups (n=10 each). In one group, the periosteum was prepared with a conventional periosteal elevator; in the other, a piezoelectric device was used. After graft implantation at calvarial sites, intravital microscopy was performed post-operation (day 0) and on days 3, 8, and 28 immediately to assess microvascular parameters: functional capillary density, blood flow velocity, and vessel diameter. Statistical analysis was conducted using ANOVA on ranks with p&lt;0.05.

Results:
The piezoelectric device group showed higher mean values for functional capillary density, blood flow velocity, and vessel diameter than the conventional instrument group, though differences were not statistically significant.

Conclusions:
This study suggests that periosteum preparation with a piezoelectric device does not significantly differ from conventional methods regarding microcirculatory outcomes. Either method appears viable for preserving microcirculatory integrity during bone augmentation. Further research in larger models and clinical contexts is recommended to confirm these findings.

Published: December 2024

Background. In swimming championships, strategy setting is considered to be the main factor, especially in the middle and long-distance events. Implementing a strategic change can indirectly affect the final results.
Objectives. The study aimed to find out whether there were any significant differences in reaction time (RT), final time (FT), and strategy for each split time (ST) in the men’s and women’s 400 meters freestyle events at the Olympic Games held in Tokyo (2021), Rio de Janeiro (2016), and London (2012).
Materials and methods. This study used quantitative methods with a sample size of 48 athletes. The data source included using the secondary data. Descriptive statistics are presented in the form of means and standard deviations. The Shapiro–Wilk test was used to test the normality of the data. To compare RT, FT, and ST data, the one-way ANOVA test was conducted. The linear regression test was used to determine the effect of RT on the first ST.
Results. The findings of this study indicate that there were differences in the RT of male athletes during the 3 Olympics. The study also revealed variations in average speed. In general, swimmers accelerated their speed at ST1 and ST8. This occurred at the Tokyo 2021 and Rio de Janeiro 2016 Olympics, while at the London 2012 Olympics, swimmers accelerated their speed only at ST1. Additionally, the results demonstrated that RT had an influence of 0.381 (14 %) on the first ST in male athletes, whereas the influence in female athletes was less marked — 0.066 (4 %).
Conclusions. This study concludes that ST1 and ST8 are the most crucial components in the 400 meters freestyle swimming for both male and female athletes. Coaches and athletes must be very careful in carrying out special training at the tapering stage so that athletes can achieve the right time to produce the best performance.
