Therapeutic methods to modulate skin pigmentation has important implications for skin cancer prevention and for treating cutaneous hyperpigmentary conditions. Towards defining new potential targets, we followed temporal dynamics of melanogenesis using a cell-autonomous pigmentation model. Our study elucidates 3 dominant phases of synchronized metabolic and transcriptional reprogramming. The melanogenic trigger is associated with high MITF levels along with rapid uptake of glucose. The transition to pigmented state is accompanied by increased glucose channelisation to anabolic pathways that support melanosome biogenesis. SREBF1-mediated up-regulation of fatty acid synthesis results in a transient accumulation of lipid droplets and enhancement of fatty acids oxidation through mitochondrial respiration. While this heightened bioenergetic activity is important to sustain melanogenesis, it impairs mitochondria lately, shifting the metabolism towards glycolysis. This recovery phase is accompanied by activation of the NRF2 detoxication pathway. Finally, we show that inhibitors of lipid metabolism can resolve hyperpigmentary conditions in a guinea pig UV-tanning model. Our study reveals rewiring of the metabolic circuit during melanogenesis, and fatty acid metabolism as a potential therapeutic target in a variety of cutaneous diseases manifesting hyperpigmentary phenotype.
Phase-locking patterns underlying effective communication in exact firing rate models of neural networks
Authors: Reyner-Parra David , Huguet Gemma
Published: May 2022

Macroscopic oscillations in the brain have been observed to be involved in many cognitive tasks but their role is not completely understood. One of the suggested functions of the oscillations is to dynamically modulate communication between neural circuits. The Communication Through Coherence (CTC) theory proposes that oscillations reflect rhythmic changes in excitability of the neuronal populations. Thus, populations need to be properly phase-locked so that input volleys arrive at the peaks of excitability of the receiving population to communicate effectively. Here, we present a modeling study to explore synchronization between neuronal circuits connected with unidirectional projections. We consider an Excitatory-Inhibitory (E-I) network of quadratic integrate-and-fire neurons modeling a Pyramidal-Interneuronal Network Gamma (PING) rhythm. The network receives an external periodic input from either one or two sources, simulating the inputs from other oscillating neural groups. We use recently developed mean-field models which provide an exact description of the macroscopic activity of the spiking network. This low-dimensional mean field model allows us to use tools from bifurcation theory to identify the phase-locked states between the input and the target population as a function of the amplitude, frequency and coherence of the inputs. We identify the conditions for optimal phase-locking and effective communication. We find that inputs with high coherence can entrain the network for a wider range of frequencies. Besides, faster oscillatory inputs than the intrinsic network gamma cycle show more effective communication than inputs with similar frequency. Our analysis further shows that the entrainment of the network by inputs with higher frequency is more robust to distractors, thus giving them an advantage to entrain the network and communicate effectively. Finally, we show that pulsatile inputs can switch between attended inputs in selective attention.
Healthy and sustainable diets from today to 2050—The role of international trade
Authors: Mapes Brendan R. , Prager Steven D. , Béné Christophe , Gonzalez Carlos Eduardo
Published: May 2022

The connection between international trade and food systems (un)sustainability is both contentious and critical for policy work supporting progress towards achieving the twin goals of hunger alleviation and dietary health while improving the overall sustainability of development. We characterize the food system using a set of metrics based upon the EAT-Lancet commission dietary guidelines for both over- and under-consumption of different foods to assess country-level dietary health and sustainability in tandem. Using a partial equilibrium model of agricultural production and trade, we then project the functioning of the global agricultural system to 2050 and calculate the metrics for that year. For most regions we find increased overconsumption above the expert-defined healthy and sustainable diet thresholds, with more limited progress towards closing dietary health and sustainability gaps where they currently exist. Trade influences this dynamic into the future under certain socioeconomic conditions, and we find that under a “business as usual” trade environment, future agricultural import profiles continue to be misaligned with dietary health and sustainability outcomes, suggesting the potential for early intervention in trade policy as a means to positively influence food system outcomes.
Changes in waterfowl migration phenologies in central North America: Implications for future waterfowl conservation
Authors: Andersson Kent , Davis Craig A. , Harris Grant , Haukos David A.
Published: May 2022

Globally, migration phenologies of numerous avian species have shifted over the past half-century. Despite North American waterfowl being well researched, published data on shifts in waterfowl migration phenologies remain scarce. Understanding shifts in waterfowl migration phenologies along with potential drivers is critical for guiding future conservation efforts. Therefore, we utilized historical (1955–2008) nonbreeding waterfowl survey data collected at 21 National Wildlife Refuges in the mid- to lower portion of the Central Flyway to summarize changes in spring and autumn migration phenology. We examined changes in the timing of peak abundance from survey data at monthly intervals for each refuge and species (or species group;n= 22) by year and site-specific temperature for spring (Jan–Mar) and autumn (Oct–Dec) migration periods. For spring (n= 187) and autumn (n= 194) data sets, 13% and 9% exhibited statistically significant changes in the timing of peak migration across years, respectively, while the corresponding numbers for increasing temperatures were 4% and 9%. During spring migration, ≥80% of significant changes in the timing of spring peak indicated advancements, while 67% of significant changes in autumn peak timing indicated delays both across years and with increasing temperatures. Four refuges showed a consistent pattern across species of advancing spring migration peaks over time. Advancements in spring peak across years became proportionally less common among species with increasing latitude, while delays in autumn peak with increasing temperature became proportionally more common. Our study represents the first comprehensive summary of changes in spring and autumn migration phenology for Central Flyway waterfowl and demonstrates significant phenological changes during the latter part of the twentieth century.
“In your face”: The transition from physical to symbolic violence among NBA players
Authors: Lev Assaf , Tenenbaum Gershon , Eldadi Omer , Broitman Topaz , Friedland Jonathan , Sharabany Maor , Galily Yair
Published: May 2022

The NBA has undergone formative changes since commissioner David Stern began his tenure. Stern has endeavored to make the NBA a consumer-friendly and marketable league by implementing sanctions on physical violence. This study takes a closer look at Stern’s efforts by examining the interplay between two forms of violence in NBA basketball players on the court: “old fashioned” physical violence (PV) and symbolic violence (SV). Of the 117 NBA finals broadcast for twenty years from 1998 to 2018, a stratified random sample (36 games or 30.8%) of the violations and commentators’ comments were coded, providing a wide perspective on forms of violence over time. The findings reveal that although the number of PV incidents decreased, SV increased starting in 2014, to the extent that SV incidents were more frequent than PV. A thematic analysis of the commentators’ remarks associated with these incidents showed that they support and encourage PV, whereas SV tends to be perceived as harmless and therefore permissible to ignore. Unlike PV, SV is not perceived to be as worthy of media coverage. The relative lack of commentator interest is indicative of the lack of “glamour” of SV in the NBA league. It is suggested that since viewers of professional sports often emulate the players, the increase of SV within the NBA is likely to be mirrored in fans in their everyday lives and in amateur basketball players. Although the rise in SV causes fewer physical injuries in professional basketball players, it nevertheless can cause psychological harm.
How digital finance affects income distribution: Evidence from 280 cities in China
Authors: Youxue Jiang , Shimei
Published: May 2022

This paper empirically tests the relationship between digital finance and income distribution of residents in 280 cities in China from 2011 to 2020 using linear and nonlinear models, respectively. Based on the Greenwood-Jovanovic (G-J) theory of output grow, the empirical study shows that there is a Kuznets effect of digital finance development on the income distribution of Chinese residents, and most regions have not yet crossed the inflection point of the bell-shaped curve, and the income gap within regions will continue to increase with the development of digital finance. Furthermore, the threshold model test shows that the positive effect of digital finance on the income disparity of residents may initially increase with the increase of regional economic level. However, when the regional economic development reaches a higher stage, the negative effect of digital finance development on the income distribution of residents will be significantly reduced.
Is routine Vitamin A supplementation still justified for children in Nepal? Trial synthesis findings applied to Nepal national mortality estimates

Published: May 2022

Background

The World Health Organization has recommended Vitamin A supplementation for children in low- and middle-income countries for many years to reduce child mortality. Nepal still practices routine Vitamin A supplementation. We examined the potential current impact of these programs using national data in Nepal combined with an update of the mortality effect estimate from a meta-analysis of randomized controlled trials.

Methods

We used the 2017 Cochrane review as a template for an updated meta-analysis. We conducted fresh searches, re-applied the inclusion criteria, re-extracted the data for mortality and constructed a summary of findings table using GRADE. We applied the best estimate of the effect obtained from the trials to the national statistics of the country to estimate the impact of supplementation on under-five mortality in Nepal.

Results

The effect estimates from well-concealed trials gave a 9% reduction in mortality (Risk Ratio: 0.91, 95% CI 0.85 to 0.97, 6 trials; 1,046,829 participants; low certainty evidence). The funnel plot suggested publication bias, and a meta-analysis of trials published since 2000 gave a smaller effect estimate (Risk Ratio: 0.96, 95% CI 0.89 to 1.03, 2 trials, 1,007,587 participants), with the DEVTA trial contributing 55.1 per cent to this estimate. Applying the estimate from well-concealed trials to Nepal’s under-five mortality rate, there may be a reduction in mortality, and this is small from 28 to 25 per 1000 live births; 3 fewer deaths (95% CI 1 to 4 fewer) for every 1000 children supplemented.

Conclusions

Vitamin A supplementation may only result in a quantitatively unimportant reduction in child mortality. Stopping blanket supplementation seems reasonable given these data.
Elevated breast cancer mortality among highly educated Asian American women
Authors: Medina Heidy N. , Callahan Karen E. , Koru-Sengul Tulay , Maheshwari Sfurti , Liu Qinran , Goel Neha , Pinheiro Paulo S.
Published: May 2022

Background

Postmenopausal breast cancer (PMBC) is the most commonly diagnosed and the second leading cause of cancer death among women in the US. Research examining the association between PMBC and education level has been inconsistent; no study in the US has examined how educational level impacts PMBC mortality in Asian American women, a largely immigrant population with above-average educational attainment.

Methods

California Vital Statistics data from 2012–2017 were analyzed to derive age-adjusted mortality rate ratios (MRRs) by education level (associates degree or above referred to as “higher education”, high school, less than high school) and race [Non-Hispanic White (NHW), Asian/Pacific Islander (Asian), and its two largest subpopulations: Chinese and Filipino] from negative binomial regression models.

Results

PMBC mortality for both NHWs and Asians was greater among women with higher education compared to those who did not complete high school: NHWs had 22% higher PMBC mortality (MRR 1.22; 95% CI: 1.14–1.31) and Asians had 2.6 times greater PMBC mortality (MRR 2.64; 95% CI: 2.32–3.00) than their counterparts who did not complete high school. Asians in the lowest education level had 70% lower mortality than NHWs (MRR 0.30; 95% CI: 0.27–0.34). This mortality advantage among Asians was greatly reduced to only 27% lower among the highest educated (MRR 0.73; 95% CI: 0.68–0.78). For higher educated Filipina women, no mortality advantage was evident compared to NHWs (MRR 0.96; 95% CI: 0.88–1.05).

Conclusion

PMBC mortality for higher educated Asian women is elevated in comparison to their counterparts with less education. Given that PMBC survival is greater among those with higher education, our findings strongly suggest an excess in the incidence of PMBC (more than double) among higher educated Asian women; this warrants more research into potentially modifiable causes of PMBC in this burgeoning population.
Comparative application of testosterone undecanoate and/or testosterone propionate in induction of benign prostatic hyperplasia in Wistar rats
Authors: An Jinho , Kong Hyunseok
Published: May 2022

Testosterone undecanoate is a hormone agent with long-acting potential and is used for testosterone replacement therapy for hypogonadism. This study was designed to investigate application of testosterone undecanoate in maintaining high androgen levels for inducing benign prostatic hyperplasia more conveniently than that for testosterone propionate. We conducted two-part studies to determine the optimal dosage and dosing cycle for efficient and stable induction of benign prostatic hyperplasia using testosterone undecanoate. In the injection dosage substudy, single testosterone undecanoate dose (125, 250, 500, 750, or 1000 mg/kg body weight) was administered, and the optimal concentration was determined for 8weeks by measuring changes in testosterone, dihydrotestosterone, and 5-alpha reductase levels. And then, testosterone undecanoate was administered at the optimal dose at intervals of 1, 2, 3, or 4 weeks for 12weeks to induce benign prostatic hyperplasia. The injection dosage substudy showed dose-dependently higher and more stable levels of testosterone in groups administrated testosterone undecanoate than in groups administered testosterone propionate. In the injection cycle substudy, testosterone undecanoate-administered group stably maintained high levels of testosterone, dihydrotestosterone, and 5-alpha reductase compared with testosterone propionate-administered group for the same injection cycle; moreover, the prostate measurements, an important sign of benign prostatic hyperplasia, were significantly increased. Based on these two substudies, we determined the optimal conditions for inducing benign prostatic hyperplasia stably and more conveniently than that for testosterone propionate. This study suggests an extended application of testosterone undecanoate for inducing benign prostatic hyperplasia that can improve research reliability considering the half-life of testosterone as well as injection dosage and concentration.

La operación Madrid Río y sus efectos en términos de selección socio-demográfica
Authors: Galiana Martín Luis
Published: May 2022

La remodelación de la autopista M-30, tunelizando su trazado a lo largo del río Manzanares, ha permitido crear una nueva zona verde sobre los terrenos liberados del tráfico: Madrid Río. Tras su inauguración en 2011, la denuncia sobre los posibles efectos gentrificadores sobre los barrios adyacentes ha sido recurrente. El artículo pretende mostrar si la producción de renta urbana diferencial propiciada por la mejora ambiental ha generado un proceso de renovación-sustitución de la población residente. Para ello se aborda el análisis de los cambios socio-demográficos y de la evolución del nivel de renta experimentado en su entorno más próximo a nivel de sección censal. Los resultados demuestran que los cambios están estrechamente vinculados con las características del tejido residencial preexistente, respondiendo a procesos urbanos más amplios (renovación de antiguas zonas industriales, incremento de la multiculturalidad en relación con la reciente oleada inmigratoria) más que a efectos directamente atribuibles a la operación. Frente a la generalizada interpretación de estos procesos bajo la narrativa de la gentrificación, la importancia de la geografía del parque residencial (expresada en términos de localización y atributos físicos y sociales) es determinante para encontrar argumentos explicativos al proceso de selección socio-demográfica.

growth of some microorganisms, among all the compounds Co(II) complex showed the highest activity.
The antifungal activity of the compounds were tested against two strains, whereas Ni(II) complex
showed the highest activity against fungal strains. Lastly, the probable binding sites of metal complexes
with receptor RpsA were studied by molecular docking studies.
The Effect of Role Conflict and Ethical Sensitivity on Auditor Performance with Moderation of Emotional Intelligence
Authors: Lase Elvina , Hwee Teng Sauh , Edward Yusuf Ronny
Published: May 2022

Auditors are required to be professional to carry out their duties properly in examining the client's financial statements to provide benefits to the client and interested parties on the audit results. However, this professional attitude cannot be separated from the auditor's role conflict and his ability to make ethical decisions. Therefore, this study aimed to examine the effect of role conflict and ethical sensitivity in improving the auditorâ€™s performance using emotional intelligence as a moderating variable. The cluster sampling technique was used to determine the number of samples, as many as 86 auditors at the Medan City Public Accounting Firm. The data was collected using a questionnaire method. Fifty-six auditors were used for hypothesis testing and research analysis, while 30 other auditors were used to determine validity and reliability tests. This study uses a structural equation model to test the hypothesis. The results show that role conflict harms auditor performance, while ethical sensitivity increases auditor performance. On the other hand, emotional intelligence does not mediate the effect of role conflict and ethical sensitivity on auditor performance. The implication of the results of this study is the need for public accounting firms to manage internal competition between auditors so as not to lead to personal conflicts that can decrease audit quality. Public accounting firms also need to develop an ethical culture among their auditors.

Published: May 2022

El artículo presenta parte de los resultados de una investigación más amplia que analizó, a partir del estudio de las percepciones de estudiantes secundarios, las mediaciones entre la configuración de la confianza de los estudiantes hacia la escuela y la producción de prácticas vinculadas a las violencias en el marco de ciertas transformaciones estructurales y el surgimiento de nuevos procesos que reconfiguran el espacio social (mutaciones en las instituciones sociales), sectores cada vez más numerosos de la población con limitaciones objetivas para encontrar un lugar en los sistemas de interdependencia, conformación y permanencia de vínculos débiles y del surgimiento de "nuevas" formas de violencia. Para ello se aplicó un cuestionario a 663 jóvenes que en 2006 cursaban los últimos años en escuelas estatales de cuatro ciudades de la Argentina. Entre los resultados obtenidos, observamos que los estudiantes conciben a la escuela como una institución confiable y que uno de los factores que más intensamente se asocia a dicho sentimiento de confianza son las representaciones que ellos poseen acerca de la justicia impartida por las autoridades escolares.

Tracking transnational Shakira on her way to conquer the world
Authors: Gontovnik Monica
Published: May 2022

The Colombian singer and composer Shakira, has become a transnational musical product. Her presence on the world stage is by now a commodity that screams the ideology of a unified globe. In the latest version of the FIFA’s World Cup (2010) she was the main musical number for the inaugural concert because her proposed song was chosen as the event’s anthem. Controversy for her use of a song from Cameroon that was popular in Colombia in the 1980s was diffused on time by good political moves. With this latest song and video, Shakira again represents her “blackness”, her “Caribbeaness”, pointing strongly to a performative activity that has been having effect since she crossed the Colombian and Latin American borders in order to start recording under Miami’s pop star producing machine. I trace in this paper, through a few of her music videos, what she has chosen or asked or coached to represent, as she performs her way to global stardom: tamed otherness. An ethics of aesthetics of popular culture is what is asked though this reflection, especially since Shakira is a professed humanitarian who has created the Barefoot Foundation in order to educate marginalized Colombian children

Mucho se ha discutido sobre el decaimiento de la enseñanza de las humanidades y del poco peso que se les da a nivel institucional en los colegios de Bachillerato y de paso en las universidades. Este artículo no pretende abordar y agotar todo el tema sino presentar un aporte a la reflexión necesaria sobre el tema desde el sentido y la función de las humanidades y la filosofía en el proceso formativo de los jóvenes de hoy. En este ejercicio no pretendo discutir sobre el supuesto desplazamiento que han sufrido las humanidades al ser reemplazadas por otras asignaturas más de corte “práctico” o “exacto”, como las matemáticas, por ejemplo, sino realzar el papel de estas áreas en el papel esencial de la educación.

The research aimed to record the game called "seeker, do not give me to the wolf ", one of the traditional children's games belonging to the Gaziantep region. The research was designed as descriptive research. Individuals who have information about the game and live in Gaziantep voluntarily participated in the study. Snowball sampling method, which is one of the purposeful sampling methods, was used to determine the research group. As the data collection tool, semi-structured interview form was used and the data obtained were evaluated by content analysis. The collected data were analyzed by content analysis. According to the data obtained; the participants of the game are a group of seven-eight people, which can be a mixture of boys and girls, a person guarding the lambs (shepherd), a wolf and lambs. Its basic mentality is based on the competition between the wolf and the shepherd who tries to protect the lambs under his care. Although there is no specific playground, open areas that can provide movement space for the players are preferred. No tools or equipment are needed in the process of playing the game. In a game, which does not have a time limit, the game may continue for a long time until the players are bored or tired.

The magnetic form factors (ML) of inelastic electron scattering of magnesium nuclei 24Mg were studied computationally using Oxbash code. The energy levels of this nucleus were calculated through the shell model and using the model space (ZBM, PSD,SPSDPF and SD). For SD used two novel USD-type Hamiltonians, USDC and USDI, as well as modifications to these interactions, USDCm and USDIm. All the calculated values that were studied were compared with the available practical data, and it was also based on the data of the NNDC website. This study showed agreement between the calculated results and the experimental data after changing the values of g-factors where they were (𝑔𝑙 𝑝= 1.060 and 𝑔𝑙 𝑛= -0.060).
