Correlation Between Student Retention Actions and Brand Resonance in a Higher Education Institution

Research relating Consumer Based Brand Equity and students’ permanence intention in the educative institution, was performed. A descriptive correlational study was carried out, using a non-probabilistic sampling with 453 participants in total, which answered a survey that included the variables used by the Colombian National Education Ministry (Ministerio de Educación Nacional de Colombia) to measure permanence actions as well as other variables related with the brand equity model, which were specifically developed for the main purposes of this study. The most important results suggest a positive association between internationalization processes and the permanence intention in the institution; a correlation between perception of the permanence actions and the brand equity in the Superior Education Institution (IES, because of their acronym in Spanish); in the same way, a strong connection between Keller’s Brand resonance model and the Institutional Abandonment of Tinto’s. This evidenced relationship would allow the strengthening of permanence and lowering of student’s abandonment

Late-life depression accelerates cognitive impairment and tau-associated pathology in an Alzheimer´s disease model.

Clinical studies suggest that depression could be considered an important risk factor for the future development of cognitive impairment and Alzheimer's disease (AD). In fact, there is a strong association between late-life depression and AD. The age of AD onset has been shown to be accelerated in patients with mild cognitive impairment (MCI) with a history of depression, and women appear to be particularly more vulnerable to this condition. In addition, individuals with MCI who present depressive symptoms have an elevated burden of amyloid-beta (Aβ), the main toxic protein associated with Alzheimer's pathology, and a higher risk of developing AD compared to non-depressed MCI patients. Although it has been described that some transgenic models of AD can develop signs similar to depression in advanced stages, the induction of Alzheimer's pathology due to a depressive process has not been studied under experimental conditions to emulate late-life depression as a risk factor for AD. In this study, we induced chronic unpredictable mild stress (CUMS) in P301S tau transgenic mice to determine whether depression is a cause, rather than a consequence, of the development of AD pathology. Our results suggest that transgenic tau mice subjected to CUMS seem to develop a depressive state. This animals display enhanced cognitive impairment compared to controls. In addition, histological studies show increased tau deposition, suggesting that late-life depression could worse AD progression by accelerating tau aggregation and worsening clinical signs. The findings generated in this project could provide evidence of depression as a risk factor for AD, providing new insights on molecular mechanisms involved in AD onset and progression.Universidad de Málaga.

Late-life depression accelerates cognitive decline in a tauopathy mouse model

Background: Clinical studies suggest that depressive symptoms could be considered an important risk factor for the future development of cognitive impairment and even Alzheimer's disease (AD). In fact, there is a strong association between depression in later life and AD. The age of onset of AD has been shown to be accelerated in patients with mild cognitive impairment (MCI) with a history of depression, and women appear to be particularly more vulnerable to this condition. In addition, individuals with MCI who present depressive symptoms have an elevated burden of amyloid-beta, one of the featured toxic proteins associated with Alzheimer's pathology, and a higher risk of developing AD compared to non-depressed MCI patients. Although it has been described that some transgenic models of AD can develop signs similar to depression in advanced stages, it is unknown whether late-life depression can accelerate tau-associated pathology and, therefore, acting as a risk factor for AD. Method: In this study, we induced chronic unpredictable mild stress (CUMS) in P301S tau transgenic mice to determine whether depression is a cause, rather than a consequence, of the development of AD. Result: The results of our study indicate that the induction of CUMS in transgenic animals induces phenotypic changes related to a depressive state. Conclusion: The findings obtained after inducing late-life depression-like in P301S mice indicate that depression could be considered a risk factor for AD, by accelerating tau aggregation and worsening clinical signs.Universidad de Málaga.

Selective miRNA inhibition in CD8+ cytotoxic T lymphocytes enhances HIV-1 specific cytotoxic responses

miRNAs dictate relevant virus-host interactions, offering new avenues for interventions to achieve an HIV remission. We aimed to enhance HIV-specific cytotoxic responses—a hallmark of natural HIV control— by miRNA modulation in T cells. We recruited 12 participants six elite controllers and six patients with chronic HIV infection on long-term antiretroviral therapy ("progressors"). Elite controllers exhibited stronger HIV-specific cytotoxic responses than the progressors, and their CD8+T cells showed a miRNA (hsa-miR-10a-5p) significantly downregulated. When we transfected ex vivo CD8(+) T cells from progressors with a synthetic miR-10a-5p inhibitor, miR-10a-5p levels decreased in 4 out of 6 progressors, correlating with an increase in HIV-specific cytotoxic responses. The effects of miR-10a-5p inhibition on HIV-specific CTL responses were modest, short-lived, and occurred before day seven after modulation. IL-4 and TNF-α levels strongly correlated with HIV-specific cytotoxic capacity. Thus, inhibition of miR-10a-5p enhanced HIV-specific CD8(+) T cell capacity in progressors. Our pilot study proves the concept that miRNA modulation is a feasible strategy to combat HIV persistence by enhancing specific cytotoxic immune responses, which will inform new approaches for achieving an antiretroviral therapy-free HIV remission

Cognitive impairment acceleration after late-life depression in a model of Alzheimer´s disease

Conclusion: The findings generated in this project could provide evidence of depression as a risk factor for AD, its mechanisms of action, use as early biomarkers, as well as the discovery of new therapies for AD.Universidad de Málaga.

Selective miRNA Modulation Fails to Activate HIV Replication in In Vitro Latency Models

HIV remains incurable because of viral persistence in latent reservoirs that are inaccessible to antiretroviral therapy. A potential curative strategy is to reactivate viral gene expression in latently infected cells. However, no drug so far has proven to be successful in vivo in reducing the reservoir, and therefore new anti-latency compounds are needed. We explored the role of microRNAs (miRNAs) in latency maintenance and their modulation as a potential anti-latency strategy. Latency models based on treating resting CD4 T cells with chemokine (C-C motif) ligand 19 (CCL19) or interleukin-7 (IL7) before HIV infection and next-generation sequencing were used to identify the miRNAs involved in HIV latency. We detected four upregulated miRNAs (miRNA-98, miRNA-4516, miRNA-4488, and miRNA-7974). Individual or combined inhibition of these miRNAs was performed by transfection into cells latently infected with HIV. Viral replication, assessed 72 h after transfection, did not increase after miRNA modulation, despite miRNA inhibition and lack of toxicity. Furthermore, the combined modulation of five miRNAs previously associated with HIV latency was not effective in these models. Our results do not support the modulation of miRNAs as a useful strategy for the reversal of HIV latency. As shown with other drugs, the potential of miRNA modulation as an HIV reactivation strategy could be dependent on the latency model usedThis work wasfunded by the Spanish Ministry of Economy and Competitiveness(PIE 13/00040) and the Spanish AIDS Research Network (RIS)(RD16/0025/0001) as part of the Plan Estatal I+D+I and co-financedby Instituto de Salud Carlos III (ISCIII)-Subdirección General deEvaluación y Fomento de la Investigación and Fondo Europeo deDesarrollo Regional (FEDER) (European Regional DevelopmentFund).

Subjetividades de las mujeres trabajadoras de diferentes edades en Colombia

El texto explora los matices que configuran la construcción de subjetividad de las mujeres en el mundo laboral en Colombia según tres grupos etarios. Se tomó información sobre estadísticas oficiales, documentos entorno a la construcción de subjetividad y artículos acerca las mujeres en el ámbito laboral, entre otros datos. A través de análisis cualitativo de entrevistas semiestructuradas de sus experiencias, se revelaron diferentes sujetos y posturas frente al trabajo y factores que dan luces sobre el concepto de techo de cristal. Se logró una descripción sobre las dinámicas cambiantes de ámbito laboral, como un espacio donde la subjetividad femenina se construye según las necesidades del contexto y las propias, que también son determinadas por este, además de una descripción de encuentros, no siempre explícitos, con el techo de cristal. Se sugiere profundizar en temas como la construcción de subjetividad según edad y no el género, según la estructura de la empresa o en sectores laborales invisibilizados.The paper explores the factors that influence Colombian women’s construction of subjectivity in the working industry, taking into acount three age groups. This investigation gathered information from official statistics, papers on construction of subjectivity and articles about woman in the work sphere among other data. Through a qualitative analysis of semi structured interviews containing the working experience of these women, different individuals and attitudes towards work were found as well as some elements that send attention over the concept glass ceiling. The results show a description of the changing dynamics of the working world as an ambit where feminine subjectivity is constructed according to needs made by their context. Also a description of encounters with the glass ceiling, in some cases explicitly named. It is advisable to do further investigations on construction of subjectivity according to age and not to gender, taking into account the structure of the company and include jobs that are invisible for some parts of society.Psicólogo (a)Pregrad

The influence of gender and body dissatisfaction on body‐related attentional bias: An eye‐tracking and virtual reality study

Objective In the attentional bias (AB) phenomenon, eating disorder (ED) patients show a tendency to pay more attention to self‐attributed unattractive body parts than to other body parts. However, little research has focused on gender differences in body‐related attention, controlling for body dissatisfaction (BD). This study aimed to assess gender differences in AB toward specific weight‐ or nonweight‐related body parts using a virtual reality (VR)‐based embodiment technique and an eye‐tracking AB assessment. Method Forty‐five women (23 with high BD and 22 with low BD) and 40 men (20 with high BD and 20 with low BD) were subsequently embodied in three virtual avatars, the first based on the participant's actual measurements, the second being larger than the participant, and the third being the same as the first avatar. The number of fixations and complete fixation time on weight‐related areas of interest (W‐AOIs) and nonweight‐related areas of interest (NW‐AOIs) were recorded for the three assessment time/avatars. Results The results showed a statistically significant interaction between gender and time for total fixation time and number of fixations (p < .05). BD levels did not significantly affect the results. Overall, women paid more attention to the W‐AOIs than men, who in turn paid more attention to the NW‐AOIs. Furthermore, preliminary evidence was found for an AB toward muscular‐related AOIs among men. Conclusions This study provides new information about gender differences and BD in gaze pattern behaviors. Future psychological ED assessments and treatments could take advantage of the possibilities of VR while real‐time AB is objectively measured
