- Associations between cues of sexual desire and sexual attitudes in portuguese womenPublication . Silva, Juliana; Ferreira, Susana; Barros, Vanessa; Mourão, Ana; Corrêa, Gabriela; Caridade, Sónia; e Sousa, Hélder Fernando Pedrosa; Dinis, Maria Alzira Pimenta; Leite, ÂngelaSexuality is defined as a multidimensional experience that involves genital, mental, and bodily components. It is also assumed as a basic condition inherent to the human existence that encourages the search for love, intimacy, sex, and proximity to others. The main objective of this study is to assess the relationship between cues of sexual desire and sexual attitudes in Portuguese women. This is a cross-sectional study with 804 Portuguese women to whom the protocol was applied. It included an informed consent, a sociodemographic questionnaire, a questionnaire related to intimacy, a scale of sexual attitudes, and the scale of cues of sexual desire. The protocol was applied via Google Forms due to the current pandemic situation (COVID-19). Differences were found in sexual attitudes and the cues of sexual desire in terms of sociodemographic characteristics, as well as in terms of women’s intimacy. Significant correlations were found between the brief sexual attitudes scale (BSAS) and the cues of sexual desire scale (CSDS). Age, sexual orientation, relation nature, sexual practices, visual proximity cues, erotic explicit cues, and sensory explicit cues explain, altogether, 25% of the total sexual attitudes. Additionally, age, sexual orientation, the relation’s nature, sexual practices, visual proximity cues, emotional bonding cues, romantic implicit cues, erotic explicit cues, and sensory explicit cues explain, altogether, 30% of the permissiveness. Sexual attitudes are developed under the influence of sociodemographic variables, variables related to women’s intimacy, and cues of sexual desire, which are new data in the study of sexual attitudes and have implications at the level of gender issues.

- Genetic and environmental factors involved in schizophrenia developmentPublication . Cardoso, Inês Lopes; Silva, JulianaDue to its complexity, schizophrenia is an intriguing disorder being described as a heterogeneous and multifactorial disease. It is characterized by the presence of a psychotic behavior, unrealistic and disorganized thinking, and a marked social dysfunction. This disorder affects 1% of world population presenting a high impact at family level and huge expenditure on public health. In this paper we intend to perform a bibliographic search concerning the genetic and environmental risk factors involved in schizophrenia development. A bibliographic search was performed using the words: schizophrenia, genetic factors, non-genetic factors, multifactorial heritage. Criteria used in papers selection included the interest of the subject, limiting the search to scientific papers written in English or Portuguese, with publication date in a 10 years period or of previous years when the content and experimental evidences were relevant for the theme. As results of this search, it was seen that the genetic influence in this pathology is well stablished, however, the exact nature of the type of transmission is not clear yet. Several environmental factors involved in schizophrenia development have already been identified. Available data allow to conclude that, in most cases, the genetic component consists of multiple genes acting additively, being the genotype expressed only when the number of genes and non-genetic factors present is above a threshold number.
- Incorporation of lipid nanosystems containing omega-3 fatty acids and resveratrol in textile substrates for wound healing and anti-inflammatory applicationsPublication . Silva, Juliana; Mesquita, Rui; Pinho, Eva; Caldas, Ana; Oliveira, M. E. C. D. Real; Lopes, Carla Martins; Lúcio, Marlene; Soares, GraçaIn the present work, lipid nanosystems containing omega-3 fatty acid (nanostructured lipid carriers, NLCs) or omega-3 fatty acid and resveratrol (liposomes) were developed to improve cotton textile substrates as dressings with anti-infammatory properties for wound healing applications. Lipid nanosystems were incorporated into woven, non-woven and knitted cotton substrates by exhaustion and impregnation. Based on physical–chemical characterization of the textile substrates, the textile structure and type of lipid nanosystems dictated the adsorption efciency. In the case of NLCs, the woven substrate functionalized by exhaustion had a higher omega-3 release being the most promising for wound dressing application. Whereas for liposomes, the most adequate textile was the cationized knitted fabric functionalized by impregnation, that showed a more prolonged release profle of resveratrol.
- Incorporation of lipid nanosystems containing omega-3 fatty acids in textile substrates for wound healing and applicationsPublication . Silva, Juliana; Mesquita, Rui; Pinho, Eva; Caldas, Ana Rita; Lopes, Carla Martins; Lúcio, Marlene; Soares, GraçaThe present work developed omega-3-loaded liposomes and nanostrucutres lipid carriers (NLC) to improve cotton textile substrates as wound dressing. The lipid nanosystems were incorporated into woven, non-woven and knitted cotton substrates by exhaustion and impregnation. Based on the physical-chemical characterization of the developed wound dressings, the textile strucute and type of lipid nanosystem dictated the incorporation efficiency.
