Educación Superior Pública: macrotendencias en tiempos de Mundialización del Capital
Authors: Meoño Molina Rita 
Published: August 2023

Introducción: El capitalismo como modo de producción imperante a nivel planetario viene reconfigurándose y, desde hace varias décadas exhibe nuevos patrones en su funcionamiento que impactan todas las esferas de la vida en sociedad, entre ellas la educación. La humanidad atraviesa por un momento histórico en el que la sociedad fue convertida en un gran mercado y la educación superior pública pasó a ser tratada como «mercancía».
Objetivos: Demostrar que, en el actual momento de evolución del sistema capitalista, la educación superior está siendo disputada, para convertirla en un instrumento más al servicio del capital.
Método y Técnicas: Con perspectiva latinoamericana, y utilizando el método histórico crítico de base marxista, el artículo recurre a la revisión bibliográfica para abordar diferentes macro-estrategias que están impactando la Educación Superior Pública en la Región y en el contexto costarricense.
Resultados: La educación superior hoy está siendo transfigurada para que deje de ser un bien público, un derecho social y universal y se convierta en un servicio mercantil más.
Conclusiones: Constantes luchas por presupuestos estatales; un explosivo crecimiento de instituciones del sector privado; sistemas de acreditación que apuntan no solo a desdibujar las diferencias y tensiones entre sector público y el sector privado, sino también a impulsar procesos de internacionalización y la transnacionalización de la educación superior a nivel Regional y mundial; lesiones a la autonomía universitaria; así como modificaciones en las condiciones laborales del trabajo académico; son parte de las tendencias contemporáneas que atentan contra la Universidad Pública Latinoamericana.

Highlight Research

The methanolic extracts of salinaand B. braunii contained alkaloids, steroids, triterpenoids, flavonoids, and saponins.
Chlorophyll a, chlorophyll b, and carotenoids were most abundant in the ethyl acetate extracts of salinaand B. braunii.
The maximum total phenolic content was observed in the n-hexane extract of salina(61.28 mg GAE/g sample) and the ethyl acetate extract of B. braunii (46.94 mg GAE/g sample).
The n-hexane extracts exhibited the highest antioxidant activity, whereas saponins were most abundant in the methanol extracts.

Abstract
Microalgal species such as Dunaliella salina and Botryococcus braunii are reportedly rich in natural antioxidants and phytochemicals. This study aimed to determine the phytochemicals and the antioxidant activity of D. salina and B. braunii. Microalgal samples were obtained from the Brackish Water Cultivation Fisheries Center (BPBAP), Situbondo, East Java. The extracts were prepared using the multilevel maceration method. The antioxidant activity of the algal species was analyzed using 1,1-diphenyl-2-picrylhydraxyl (DPPH). Quantitative analysis revealed that D. salina and B. braunii contained antioxidants, indicated by the appearance of yellow spots on the purple background of the TLC plate. The n-hexane extract of D. salina exhibited the highest antioxidant activity with a half-maximal inhibitory concentration (IC50) of 443.28 ppm, 61.28 mg GAE/g sample of total phenolics, 0.106 mg/g of chlorophyll a, 0.165 mg/g of chlorophyll b, and 1,697 mol/g of carotenoids. In contrast, the ethyl acetate extract of B. braunii exhibited the highest antioxidant activity with an IC50 of 634.55 ppm, 46.94 mg GAE/g sample of total phenolics, 18.146 mg/g of chlorophyll a, 12.592 mg/g of chlorophyll b, and 4573 mol/g of carotenoids. The microalgal species used in this study exhibited extremely weak antioxidant activity.

Economic performance of commercial fishing industry in Pahang State, East Coast of Peninsular Malaysia.
Comparison of accounting profit between the two prominent fishing gear types: trawlers and purse seine in Pahang State
Comparison of accounting profit between the different zones of fishing operations by the trawlers and purse seine
Research findings showed that trawlers give more profit than purse seine vessels in Pahang State and overcapacity and over exploitation is distinctly found in Pahang State commercial fishing industry.
This study suggested that other analysis such as biological performance by this study area should be done in future coupled with the analysis of impact of management policies on the sustainability of the fishery.

Abstract
Marine capture fisheries in Malaysia plays prominent role in economic growth and commercial fisheries makes great contribution to country’s economy. The commercial fishing industry in East Coast of Peninsular Malaysia are mainly operated by trawlers and purse seines which rises a major concern in managing and achieving the goal of sustainable fishery. This study aimed to account the differences of accounting profit level in commercial fishing industry in Pahang State, East Coast of Peninsular Malaysia. In this study, comparison of accounting profits using revenue and profit approach among trawl and purse seine fishery in two different zones: Zone C (offshore) and Zone C2 (deep sea) was carried out based on the intensive survey on fishing capacity and other economic factors. The survey was carried out with the commercial fishermen and total respondents of 156 fishers at landing port. The result showed that trawlers incurred low cost yet provided higher profit than doses by purse seine. Moreover, there are more trawlers vessels operating in the Pahang state fishing ground and the open access nature of the fishery like larger profit invites more effort to use in the fishery which is leading to the over exploitation of fishery resources and threatening the sustainable condition of the fishery. The findings of the research inform the possible impact of fishing profit to overcapacity in sustainable fishery management in Pahang State fishery.

Update
This article was updated on April 5, 2024, because of a previous error. On page 2, in the bottom right of Figure 1, the text that had previously read “202 (43%) patients with Isolated Radial Fractures” now reads “202 (43%) patients with Both-Bone Fractures.”
An erratum has been published: JBJS Open Access. 2024;9(2):e22.00115ER.

Background:
The incidence of and risk factors for adverse events after internal fixation of diaphyseal forearm fractures have not been well defined in the current literature. The objective of this study was to estimate the incidence of adverse events after diaphyseal forearm fracture surgery in adults and explore potential risk factors for adverse events.

Methods:
We conducted a retrospective, multicenter, cohort study in which we evaluated all diaphyseal forearm fractures between 2009 and 2019 in patients presenting to 4 trauma hospitals in southern Finland. Patients <16 years of age and fracture-dislocations were excluded. There were 470 patients included in this study. Patient records were evaluated to identify and analyze adverse events.

Results:
There were 202 patients with both-bone fractures, 164 patients with isolated ulnar fractures, and 104 patients with isolated radial fractures. In total, 146 patients (31%) experienced an adverse event; 83 (18%) had major adverse events (persistent or requiring surgical intervention). The patients underwent procedures performed by 185 different surgeons. The median number of operations for a single surgeon was 2 (range, 1 to 12). The most common major adverse events were plate and screw-related issues (6%), nonunion (5%), persistent nerve injuries (4%), and refractures (4%). Higher body mass index, Gustilo-Anderson type-II open fractures, both-bone fractures, isolated radial fractures, and operations performed by junior residents were found to be risk factors for adverse events in the multivariable analysis.

Conclusions:
Adverse events after diaphyseal forearm fracture surgery are common. We recommend concentrating these operations in a limited team of surgeons and restricting inexperienced surgeons from operating on these fractures without supervision.

Authors: Su Gao-Jian , Zhang Di , Wu Jia-Nuo , Deng Yu-Hang , Wu Chu-Wei , Liu Gao-Lin , Huang Xian-jian 
Published: August 2023

Abstract
Background
Chronic subdural hematoma (CSDH) is a common neurological disorder in older patients, and immediate outcomes of surgery for CSDH are satisfactory. However, the evidence for subperiosteal drainage (SPD) versus subdural drainage (SDD) in CSDH remains controversial. In this study, we aimed to assess the latest evidence on the use of SPD versus SDD in patients with CSDH who underwent burr hole evacuation.
Methods
We performed a systematic literature search on the use of SPD compared with that of SDD in patients with CSDH in PubMed, Web of Science, Embase, and Cochrane online databases from inception until December 2021. The inclusion and exclusion criteria were defined for eligible studies. A fixed-effects model was used when homogeneity was observed.
Results
A total of 1013 participants from six studies were included. There were no significant differences in the recurrence rate (odds ratios [OR], 0.87; 95% confidence interval [CI], 0.61–1.26; I2 = 0%; P = 0.47) or the mortality rate (P = 0.89) between the SPD and SDD groups. Additionally, various characteristics, including the rate of subsequent seizures (P = 0.74), sex distribution (P = 0.37), and favorable clinical outcome rates (OR, 1.13; 95% CI, 0.74–1.72; I2 = 0%; P = 0.58), were also similar between the two groups. Moreover, there was no significant difference in the effects of antithrombotic agents between the two groups (P = 0.12).
Conclusions
There were no differences in recurrence rates, sex distribution, postoperative mortality, seizures, favorable outcomes (modified Rankin scale score: 0–3), or effects of antithrombotic agents between the SPD and SDD groups. These findings suggest that both SPD and SDD are equally effective in treating patients with CSDH.
Leader-follower green traffic assignment problem with online supervised machine learning solution approach
Authors: Sadra Mahmud , Zaferanieh Mehdi , Yazdimoghaddam Jafar 
Published: August 2023

Abstract

In this paper, we propose a bi-level traffic assignment problem where at the upper-level the total traffic CO emission objective function is evaluated and at the lower level, the traffic assignment objective function is considered. At the upper level, the total emission objective function is considered as the main objective from a macroscopic view point of the system manager. At the lower level, the traffic assignment problem is considered to optimize the users’ travel times, individually. Although the lower-level objective function is convex with some linear constraints, the proposed bi-objective problem is np-hard, and even finding a near-optimal solution is also np-hard. Hence, we applied a pioneer online supervised machine learning (SML) algorithm to find the optimal solutions in a reasonable running time. The validity of the online SML is verified through some real urban transportation examples in medium and large-sized networks.
More than three-fold increase of compound soil and air dryness across Europe by end of 21st century
Authors: Shekhar Ankit , Humphrey Vincent , Buchmann Nina , Gharun Mana 
Published: August 2023

Abstract
Increases in air temperature leads to increased dryness of the air and potentially develops increased dryness in the soil. Extreme dryness (in the soil and/or in the atmosphere) affects the capacity of ecosystems for functioning and for modulating the climate for example through CO2 uptake or evaporative cooling. Here, we used daily soil moisture and vapor pressure deficit data of high spatial resolution (~ 0.1° ´ 0.1°) from 1950-2100 to show that compared to the reference period (1950-1990), the frequency and intensity of extreme soil dryness, extreme air dryness, and compound extreme dryness (i.e., co-occurrence of extreme soil and air dryness) has increased over last 31 years (1991-2021) and will further continue to increase in the future until 2100 across Europe. This increased intensity and frequency was most pronounced over broadleaved forests, croplands, and grasslands. Such future climate-change induced increase in extreme dry conditions could alter ecosystem functioning across Europe.

Abstract
The spatiotemporal configuration of genes with distal regulatory elements, and the impact of chromatin mobility on transcription, remain unclear. Loop extrusion is an attractive model for bringing genetic elements together, but how this functionally interacts with transcription is also largely unknown. We combine live tracking of genomic loci and nascent transcripts with molecular dynamics simulations to assess the spatiotemporal arrangement of the Sox2 gene and its enhancer, in response to a battery of perturbations. We find a close link between chromatin mobility and transcriptional status: active elements display more constrained mobility, consistent with confinement within specialized nuclear sites, and alterations in enhancer mobility distinguish poised from transcribing alleles. Strikingly, we find that whereas loop extrusion and transcription factor-mediated clustering contribute to promoter-enhancer proximity, they have antagonistic effects on chromatin dynamics. This provides an experimental framework for the underappreciated role of chromatin dynamics in genome regulation.
Is a Keystone Bone Anomaly The Main Cause of Pes Planus?
Authors: Payas Ahmet , Batın Sabri 
Published: August 2023

Abstract
Background
In flexible pes planus, the height of the arcus pedis longitudinalis medialis (APLM) collapses during weight bearing. We think that this may be caused by anomalies in the bones that support the arches against the compression load. For this purpose, the volume (cm3) and superficial area (cm2) ratios of the foot bones were calculated using foot computed tomography (CT) images of individuals with pes planus and compared with healthy individuals
Methods
Fifteen pes planus patients diagnosed with pes planus in our clinic and with an APLM angle greater than 145 degrees and 15 healthy male participants were included. The foot computed tomography (CT) images of the participants were taken with a General Electric brand IQ model 32 detector CT device in accordance with the bone protocol, with a section thickness of 0.625 mm. Foot bones were segmented from the obtained CT images with the help of the 3D Slicer program.
Results
The os cuneiforme mediale and os cuneiforme intermedium volume and superficial area ratios of the pes planus group were significantly lower than the control group (p < 0.05). There was no difference between the groups in the volume and superficial area ratios of the other foot bones (p > 0.05).
Conclusion
We think that pes planus is primarily caused by os cuniforme mediale and os cuneiforme intermedium developmental anomalies, which act as a keystone in the formation of arches.

Abstract
Raman spectroscopy provides non-destructive, label-free quantitative studies of chemical compositions at the microscale as used on NASA’s Perseverance rover on Mars. Such capabilities come at the cost of extremely high requirements for instrumentation. Here we present a centimeter-scale miniaturization using cheap non-stabilized laser diodes, densely-packed optics, and non-cooled small sensors, while the performance is comparable with expensive bulky research-grade Raman systems. It has excellent sensitivity, low power consumption, perfect wavenumber, intensity calibration, and 7cm-1 resolution within the 400–4000 cm-1 range using a built-in reference. We present solutions to Raman miniaturization challenges: laser temperature and power stabilization, reduction of sensor dark noise, compensation on pixel-to-pixel quantum efficiency variation, laser optical isolation and high spectral resolution. Moreover, shifted-excitation Raman difference spectroscopy (SERDS) and spatially offset Raman spectroscopy (SORS) functions are compatible. High performance and versatility are demonstrated in use cases including quantification of methanol in beverages, in-vivo Raman measurements of human skin, quantification of p-coumaric acid and serine in bacterial fermentations, chemical Raman mapping at sub-micrometer resolution, quantitative SERS mapping of the anti-cancer drug methotrexate and in-vitro bacteria identification by Raman mapping. We foresee that the miniaturization will allow realization of super-compact Raman spectrometers for integration in smartphones and medical devices, democratizing Raman technology.

Abstract
Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), world-renowned as spotted-wing drosophila, is an invasive pest mainly affecting healthy, soft and stone fruit crops throughout Argentinian fruit-growing regions. Natural environments overgrown by exotic feral host plants apparently favour D. suzukii proliferation. This is common in the subtropical north-western Argentina's berry-producing region. An assemblage of resident parasitoid species has been associated with D. suzukii in crop and non-crop areas of Tucumán, the Argentina's leading berries producer and exporter. Consequently, the hypothesis that the combined action of two pupal parasitoid species, Pachycrepoideus vindemiae Rondani (Hymenoptera: Pteromalidae) and Trichopria anastrephae Lima (Hymenoptera: Diapriidae), occurring in non-crop fruit areas, has a significant impact on D. suzukii natural regulation in such invaded habitats was tested. A survey of D. suzukii puparia from both feral peach [Prunus persica (L.) Batsch] (Rosaceae) and guava (Psydium guajava L.) (Myrtaceae) fallen fruits and soil surrounding them was performed in a wilderness area of Tucumán. Fruit infestation level and parasitism rates were assessed. Whole of 3,437 D. suzukii puparia were recovered; 78% and 22% were surveyed from fruits and soil underneath the fruit, respectively. Both P. vindemiae and T. anastrephae accounted for 99.8% of total parasitoid individuals. Both tested fruits are important D. suzukii multiplying hosts. Both parasitoids are relevant contributors to the D. suzukii natural mortality, as they killed a quarter of all puparia. Mostly T. anastrephae foraged on host puparia located in the fruit and P. vindemiae in both microhabitats. This information supports an augmentative biological control strategy in non-crop areas.

AbstractAim:The mental health of college students, especially medical students, is a major issue worldwide. Depression and anxiety are among the top causes of death among people aged 15 to 29 years old. Mental health disorders, especially mood disorders such as depression and anxiety, are common among university students. Psychological problems can negatively impact academic performance and life satisfaction. The earlier mental illness is detected, the better the treatment and outcome. This study aimed to determine the barriers among students to seeking mental health services. Knowing these will improve the services provided by the student wellness clinic.Methods:This cross-sectional questionnaire-based study was carried out at King Saud bin Abdulaziz University for Health Sciences (KSAU-HS), Riyadh, Saudi Arabia The cross-sectional questionnaire-based study involved 434 students: 72.1% men and 27.9% women. This study had a response rate of 28.5% and responses were gathered in May 2023.Results:The top 3 barriers identified in this study were “Feeling that my problems are not important,” “Concern that no one will understand my problems,” and “Difficulty with access to care.” The majority of students reported feeling “I feel reluctance a little” to use mental health services; 31.4% chose “I need it a little” when asked whether they needed to use mental health services. Furthermore, 34.8% of students had mild anxiety, and 34.1% had mild depression.Conclusion:Mental illness is a serious issue, which is why medical students should be aware of it to improve their quality of life and reduce the stress and obstacles they face. Medical schools should address awareness of mental illness and how to approach a clinic. This is important for students to succeed and overcome the psychological difficulties that might affect academic performance. In addition, recognizing the barriers will help achieve better outcomes in seeking help and utilizing existing services.
