According to the problems on public insecurity that exist in several Latin American countries like Mexico, gender-based violence has increased its importance due to the speed and dimensions of the phenomenon, which urgently demands the study of the deep-rooted machismo that still survives in these countries. It seems that cultural processes that encourage gender violence play an important role in this issue because they reinforce gender stereotyping by the impacts of cultural consumption. In these sense, mass media frequently uses stereotypical gender images that invade contemporary life of men and women. Those images usually promote opposite, confronted and intolerant social roles for girls and boys creating an identity construction. That is why the main objective of this paper is to illustrate some habits, behaviors and cultural consumptions that promote social gender ideals for children and young people that reinforce the ancestral confrontation of men and women. Hopefully this manuscript will contribute in the analysis of negative gender stereotyping that has been socially assumed as "natural", invisible or unavoidable.

Understanding and optimizing the energy consumption of wireless devices is critical to maximize the network lifetime and to provide guidelines for the design of new protocols and interfaces. In this work, we first provide an accurate analysis of the energy performance of an IEEE 802.11 WLAN, and then we derive the configuration to optimize it. We further analyze the impact of the energy configuration of the stations on the throughput performance, and we discuss under which circumstances throughput and energy efficiency can be both jointly maximized and where they constitute different challenges. Our findings are that, although an energy-optimized configuration typically yields gains in terms of throughput as compared against the default configuration, it comes with a reduction in performance as compared against the maximum-bandwidth configuration, a reduction that depends on the energy parameters of the wireless interface.

Purpose: This study aimed to determine the patterns of follow-up visits for cervix cancer in a national cancer center in Mexico. Materials and Methods: The National Cancer Institute of Mexico is cancer center with 119 beds that mostly cares for an underserved and socially disadvantaged population. The medical records of cases of cervical cancer that had at least one year of clinical follow-up after being in complete response at the end of primary treatment were analyzed. We recorded the numbers of total and yearly follow-up visits and these were compared with the number of follow-up visits recommended by the National Comprehensive Cancer Network 2013, version 2 for cervical cancer. Results: Between March and June 2007, the medical records of 96 consecutive patients were reviewed. Twenty (21%) of these met inclusion criteria and were selected. In the first year the median number of visits was 11 (4-20). In the ensuing years, $2^{nd}$, $3^{rd}$, $4^{th}$ and $5^{th}$, the number of analyzed patients remaining in follow-up decreased to 17, 14, 13 and 9 respectively. There were 462 follow-up visits to primary treating services (Gynecology Oncology, Radiation Oncology and Medical Oncology) as compared to 220 suggested by the NCCN guidelines ($X^2$ test p<0.0001). There were 150 additional visits to other services. Conclusions: Our results suggest that in our institution there is an overuse of oncological services by cervical cancer patients once treatment is completed.

In this bioprospecting study the biologicalactivities of extracts of the in vitro culture of GanodermaMexican strains were evaluated. The extracts were testedby the Sulforhodamine B staining method for antiproliferativeactivity and the plate microdilution method forantibacterial activity. Extracts that proved bioactive inthese two activities, the antioxidant activity (Galvinoxyl,ABTS, and DPPH) and total phenolic contents (Folin-Ciocalteu) were additionally determined, as well as acutetoxicity (Artemia franciscana). In the antiproliferativeactivity Ganoderma curtisii strain (GH-16-015) obtained aremarkable value of GI50 B 50 lg/mL against tumorlines: A549, HBL-100, HeLa, and T-47D. G. curtisiistrains (GH-16-012 and GH-16-015) showed MIC values= 500 lg/mL against Staphylococcus aureus. G. curtisiistrain (GH-16-012) almost reduced by 50% theradical Galvinoxyl. Finally, G. curtisii strain (GH-16-023)presented the lowest level of toxicity with a LC50 of490.881 lg/mL against A. franciscana. These resultssupport the potential medicinal effects of Mexican strainsof G. curtisii.

Medicinal plants represent an important resource in new drug research. Antioxidant properties of plants can help to scavenge reactive oxygen species. The objective of this work was to evaluate the genotoxic, antigenotoxic, tumoricidal, and apoptotic effect of some major phenols (apigenin, bisabolol, and protocatechuic acid) from two medicinal plants, Matricaria chamomilla and Uncaria tomentosa. The wing spot test of Drosophila melanogaster was used to evaluate the genotoxicity and antigenotoxicity of the three phenols. The human model of HL-60 leukemia cells was used for the assessment of the cytotoxic effect, growth, and cellular viability. The apoptotic effect was evaluated using a DNA fragmentation assay based on the formation of internucleosomal units. Protocatechuic acid (0.25 and 1 mM), apigenin (0.46 and 1.85 mM), and bisabolol (0.56 and 2.24 mM) did not exhibit any genotoxic effect. The three phenols showed an antigenotoxic effect against the hydrogen peroxide effect and also exhibited tumoricidal activity. Apigenin (2.24–35.96 mM) showed a lower 50% inhibitory concentration (0.75 and 3.87 mM for the trypan blue test and WST-8 colorimetric assay, respectively) than bisabolol and protocatechuic acid. These phenolics also induced apoptosis in HL-60 leukemia cells. This study suggests that the antioxidant activity of Chamomilla and Uncaria could be partially responsible of their beneficial activity.
Improving classification of low-resource COVID-19 literature by using Named Entity Recognition

Automatic document classification for highly interrelated classes is a demanding task that becomes more challenging when there is little labeled data for training. Such is the case of the coronavirus disease 2019 (COVID-19) clinical repository-a repository of classified and translated academic articles related to COVID-19 and relevant to the clinical practice-where a 3-way classification scheme is being applied to COVID-19 literature. During the 7th Biomedical Linked Annotation Hackathon (BLAH7) hackathon, we performed experiments to explore the use of named-entity-recognition (NER) to improve the classification. We processed the literature with OntoGene's Biomedical Entity Recogniser (OGER) and used the resulting identified Named Entities (NE) and their links to major biological databases as extra input features for the classifier. We compared the results with a baseline model without the OGER extracted features. In these proof-of-concept experiments, we observed a clear gain on COVID-19 literature classification. In particular, NE's origin was useful to classify document types and NE's type for clinical specialties. Due to the limitations of the small dataset, we can only conclude that our results suggests that NER would benefit this classification task. In order to accurately estimate this benefit, further experiments with a larger dataset would be needed.

Trisomy 21, or Down syndrome (DS), is the most common genetic cause of developmental delay and intellectual disability. To gain insight into the underlying molecular and cellular pathogenesis, we conducted a multi-region transcriptome analysis of DS and euploid control brains spanning from mid-fetal development to adulthood. We found genome-wide alterations in the expression of a large number of genes, many of which exhibited temporal and spatial specificity and were associated with distinct biological processes. In particular, we uncovered co-dysregulation of genes associated with oligodendrocyte differentiation and myelination that were validated via cross-species comparison to Ts65Dn trisomy mice. Furthermore, we show that hypomyelination present in Ts65Dn mice is in part due to cell-autonomous effects of trisomy on oligodendrocyte differentiation and results in slower neocortical action potential transmission. Together, these results identify defects in white matter development and function in DS, and they provide a transcriptional framework for further investigating DS neuropathogenesis.
