- Cyanobacteria in cosmetics: a natural alternative for anti-aging ingredientsPublication . Morone, Janaína; Lopes, Graciliana; Oliveira, Beatriz; Vasconcelos, Vítor; Martins, RosarioBeing exposed to endogenous and exogenous stressors, and being the body’s external defense line, skin protection is of pivotal importance, in order to maintain morphological and physiologic integrity and health. Fostering by individual psychological comfort, esthetic performance, and young appearance, along with motivation for natural products with less side effects and sustainable production, consumer’s demands drive the cosmetic industry into the relentless pursuit for innovation. In this context, cyanobacteria enforce as a promising source of ingredients with cosmetic potential. With the ability to withstand adverse conditions for survival, the adaptation to extreme environments is reflected in the production of compounds with moisturizing, photoprotective, antioxidant, and whitening potential, all attributes required in cosmetics, namely in anti-aging products. In this chapter, we will focus on the interconnection between cyanobacteria and skin, by presenting the main applications of these organisms in skincare products.
- Insights into the development of grapefruit nutraceutical powder by spray drying: physical characterization, chemical composition and 3D intestinal permeabilityPublication . González, Freddy; García‐Martínez, Eva; Camacho, María; Martínez‐Navarrete, Nuria; Sarmento, Bruno; Fernandes, Iva; Freitas, Victor; Rodrigues, Francisca; Oliveira, BeatrizThe development of functional and nutraceutical foods comes from a greater awareness of the relationship between food and health by consumers. In recent years, the idea of purifying and encapsulating bioactive compounds through techniques such as spray drying has been well received by the food industry. The development and characterization of a grapefruit (Citrus paradisi) nutraceutical powder obtained by spray drying is of great interest owing to the different bioactive compounds and the potential health effects.
- Metástase vaginal deadenocarcinoma colorretal: Diagnóstico em citologia cérvico-vaginalPublication . Mendes, Marta Daniela Valente; Oliveira, Beatriz; Cunha, Celina; Coimbra, Nuno; Duarte, Anabela; Babo, Armanda; Martins, Conceição; Monteiro, PaulaO adenocarcinoma colorretal metastático na vagina é raro e são poucos os casos descritos na literatura. O presente trabalho relata o caso de uma mulher com uma massa infiltrativa na vagina e um diagnóstico prévio de adenocarcinoma colorretal. A utilização da citologia cérvico-vaginal em meio líquido em conjunto com os marcadores imunohistoquímicos CK20 e CDX2 permitiu confirmar a origem colorretal da neoplasia. Este estudo veio reforçar a importância dos dados clínicos e da imunohistoquímica num diagnóstico, uma vez que sem estes e tendo em conta as características celulares observadas o diagnóstico poderia ser o de adenocarcinoma endocervical ou endometrial.
