Azorean Cryptomeria japonica immature female cones essential oil: Effect of hyd...
Arruda, Filipe; Lima, Ana; Janeiro, Alexandre; Rodrigues, Tânia; Baptista, José; Rosa, José S.; Machado, Alexandra; Figueiredo, Ana C.; Lima, ElisabeteABSTRACT: Cryptomeria japonica’s wood production in Azores generates large amounts of underutilized biomass residues, such as immature female cones (Az–CJIFC), that can be used to produce essential oils (EOs). Hydrodistillation (HD) can be used both to obtain and to fractionate EOs. In this study, EOs from Az–CJIFC, grinded (GR) and non grinded (NGr) fresh samples, were obtained via HD over 4 h, yielding 1.0 % ...

Arruda, Filipe; Lima, Ana; Janeiro, Alexandre; Rodrigues, Tânia; Baptista, José; Rosa, José S.; Machado, Alexandra; Figueiredo, Ana CristinaCryptomeria japonica's wood production in Azores generates large amounts of underutilized biomass residues, such as immature female cones (Az–CJIFC), that can be used to produce essential oils (EOs). Hydrodistillation (HD) can be used both to obtain and to fractionate EOs. In this study, EOs from Az–CJIFC, grinded (GR) and non-grinded (NGr) fresh samples, were obtained via HD over 4 h, yielding 1.0 % and 0.5 %,...
A Natureza “pinta” os frutos do verão para os proteger da radiação solar ultrav...
Baptista, José; Paiva, LiseteSabias que, do mesmo modo que usamos os cremes solares para protegermos a nossa pele dos efeitos negativos da radiação ultravioleta (UV), a NATUREZA usa compostos químicos coloridos para proteger os frutos do verão dos mesmos efeitos negativos criados pela radiação solar?
Angiotensin I-converting enzyme (ACE) inhibition and biological activities of g...
Paiva, Lisete; Lima, Elisabete; Marcone, Massimo; Baptista, JoséABSTRACT: The inhibition of ACE can be targeted in order to control hypertension and much attention has recently been paid towards the search for natural products as alternatives to synthetic drugs due to their adverse side effects associated with them. Camellia sinensis tea has received considerable attention due to the beneficial effects on health, particularly as a result of its antioxidant properties. The o...
The Impact of Different Withering Process Conditions on the Bioactivity and Qua...
Paiva, Lisete; Dias, Ana; Marcone, Massimo; Baptista, JoséABSTRACT: The objective of this study was to investigate the variability of natural bioactive com pounds, such as catechin, theaflavin, total phenolic content (TPC), and total flavonoid content (TFC), of Azorean black tea (Camellia sinensis L., O. Kuntze) as well as its antioxidant activities according to different withering times. The TPC, TFC, free radical scavenging activity (FRSA), ferric reducing antioxida...
A planta da Camellia sinensis: uma bênção da Natureza
Baptista, José; Paiva, LiseteSabias que no ano 2737 A.C., portanto, há cerca de 5000 anos, houve um imperador chinês, que descobriu o gosto peculiar da infusão das folhas de uma árvore, que foi classificada de Camellia sinensis pelo botânico Lineu, em homenagem ao botânico George Camel, famoso pelo seu extraordinário trabalho na classificação das plantas das Filipinas?
Determination of Melatonin in Azorean Bovine Milk by RP-HPLC as a Supplement fo...
Paiva, Lisete; Baptista, JoséABSTRACT: Melatonin (N-acetil-5-metoxitriptamine) is an indoleamine that is synthesized from the essential amino acid tryptophan via 5-hydroxytryptophan, serotonin and N-acetylserotonin in the vertebrate’s pineal gland, particularly during the nocturnal period (light suppress its biosynthesis) [1,2]. This neurohormone decreases with advancing age, paralleled by a deterioration of normal sleeping pattern and cha...
Social Representations of Trans People in the Workplace
Baptista, José; Costa, Dália; P. Gonçalves, SóniaOrganizations show tendencies to discriminate against trans people, making them significantly more likely to face barriers in the professional context, where the highest rates of discrimination against trans people are reported. This study intends to acknowledge the SRs that are associated with trans people in the workplace since the Theory of Social Representations suggests that Social Representations (SRs) ar...
Comparative Analysis of Employment Disparities, Precarity and Decent Work betwe...
Baptista, José; Costa, Dália; P. Gonçalves, SóniaWhile the societal acceptance of trans people has made strides, discrimination remains prevalent in professional settings. The concept of decent work denotes the minimal acceptable standards for the workforce. Conversely, precarity encompasses a multifaceted construct with various indicators, including unemployment. Achieving decent work necessitates the absence of discrimination, ensuring inclusivity for all i...
Investigation of the Azorean Camellia sinensis Processing Conditions to Maximiz...
Paiva, Lisete; Lima, Elisabete; Motta, Madalena; Marcone, Massimo; Baptista, JoséABSTRACT: The molecular constituents of Camellia sinensis, in particular epigallocatechin‐3‐O‐gallate (EGCG) and, more remarkably, the galloylated theaflavins, mainly theaflavin‐3,3′‐di‐O‐gallate (TF‐3,3′‐DG), have been reported to inhibit SARS‐CoV‐2 3‐chymotrypsin‐like protease (3CLpro), an enzyme required for the cleavage of its polyproteins, to produce vital individual functional proteins for viral cell repl...
