Music in DNA: From Williams Syndrome to Musical Genes

Open Journal of Genetics 2015年第1期5卷 12-26页

Williams syndrome (WS) is a genetic disorder caused by a heterozygous contiguous gene deletion on chromosome 7q11.23. Clinical features of the disease include low IQ and deficit in some cog- nitive domains, and the presence of relatively strong abilities in social drive, face processing, language, and musical skills. The presence of a strong predisposition to the development of musicality in individuals affected by WS leads us to suppose that some genes deleted in this syndrome are somehow involved in the evolution of this ability, and that these genes could act in normal conditions as “suppressors of music ability”. To test this hypothesis, we carried out an “in silico” analysis by using the Ingenuity Pathway Analysis (IPA) software to identify the interaction between genes mapped in the WS critical region and genes previously related to musical ability by literature data. This approach allowed us to identify 3 networks of interaction, involving AVPR1A, NCF1, UNC5C and LAT2 in the first network, STX1A and SLC6A4 in the second one and only WS related genes in the last one. Among these associations, the one involving STX1A and SLC6A4 suggested a possible mechanism of interaction was based on the influence played by STX1A deletion on the serotonin levels through a decrease of SLC6A4 activity.

Perceptions of Climate Change in Puerto Rico before and after Hurricane Maria

引用

American Journal of Climate Change 2021年第2期10卷 153-166页

作者： Méndez-Tejeda Rafael María Santos-corrada Mena Sandra Natural Science Department Atmospherical Science Laboratory University of Puerto Rico at Carolina Puerto Rico USA School of Business and Entrepreneurship University of Ana G. Méndez Gurabo Puerto Rico USA

This article analyzes the perceptions of Puerto Rican citizens of global climate change (GCC) before and after an extreme weather event, specifically Hurricane Maria (HM). The purpose of the current article is to evaluate Puerto Ricans’ perceptions of the impact of extreme meteorological phenomena and of GCC before and after HM. This tropical cyclone entered the island as a category IV hurricane on September 17, 2017, causing enormous destruction, loss of life, and economic damage. In this study, two data samples were collected before and after HM struck Puerto Rico (PR) (the second sample was collected approximately six months after the hurricane). Surveyed citizens with general knowledge of GCC increased from 43% to 62%, which the researchers consider a small increase, considering the severe destruction caused by HM. This study also found that Puerto Ricans trust non-profit institutions and the scientific community more than state authorities. Furthermore, 85% of citizens believe that public policies on GCC should be directed by the state (federal, state, and municipal governments);this did not change after HM. In addition, this study found that the poor response of the federal and state governments to the destruction caused by HM increased citizens’ trust in the scientific community.

Environmental and Economic Impact of Forest Fires in Puerto Rico 2013-2014

引用

Open Journal of Forestry 2015年第4期5卷 353-363页

作者： Méndez-Tejeda Rafael Santos-corrada María Ortiz-Morales Sergio Claudio-Vargas Oscar Natural Science Department Atmospherical Science Laboratory University of Puerto Rico—Carolina Campus Carolina Puerto Rico School of Business and Entrepreneurship University of Turabo Gurabo Puerto Rico

This study presents an analysis of the impact of forest fires in Puerto Rico for the period from 2013-2014. The climatological factors analyzed included precipitation, temperature, relative humidity, and wind. Several factors have combined to the increase of these forest fires, among others, a decrease in precipitation during this period, as well as an increase in the human involvement in these fires from approximately 40% occurs in the night period (5:00 pm to 8:00 am), where the weather conditions do not favor the appearance of these phenomena. An increase in fires of 44% occurred in 2013 compared to 2014, causing an economic loss of $13.8 million. Fire also adversely affected the flora and fauna of the island, but this was not evaluated in this paper.
