The main goal of this study was to produce adjusted normative data for the Portuguese population on two verbal fluency measures: the semantic fluency test (animals category) and the phonemic fluency test (letters M, R, and P). The study included 950 community-dwelling individuals (624 women and 326 men) aged between 18 and 98 (mean = 57.8, SD = 19.0), who had educational backgrounds ranging from 0 to 20 years (mean = 8.8, SD = 5.2). The results showed that age and education were significantly associated with semantic fluency and phonemic fluency performance. These demographic characteristics accounted for 42% of the semantic fluency and between 23% and 31% of the phonemic fluency performance variance. No significant sex effects were found. The normative data are presented as regression-based algorithms to adjust test scores for age and education, with subsequent correspondence between adjusted scores and percentile distribution.

The main goal of this study was to produce normative data for the Portuguese population on the Trail Making Test (TMT). The study included 1,038 community-dwelling individuals aged between 18 and 93 years, who had educational backgrounds ranging from 3 to 22 years. The results showed that sex, age, and education were significantly associated with TMT performance. These demographic characteristics accounted for 57% of the performance variance at part A and 50% at part B. The normative data are presented as regression-based algorithms to adjust direct and derived test scores for sex, age, and education. The adjusted scores' percentile distributions and their correspondence with scaled scores are also provided.

The increase of many deadly diseases like infections by multidrug-resistant bacteria implies re-inventing the wheel on drug discovery. A better comprehension of the metabolisms and regulation of diseases, the increase in knowledge based on the study of disease-born microorganisms’ genomes, the development of more representative disease models and improvement of techniques, technologies, and computation applied to biology are advances that will foster drug discovery in upcoming years. In this paper, several aspects of current methodologies for drug discovery of antibacterial and antifungals, anti-tropical diseases, antibiofilm and antiquorum sensing, anticancer and neuroprotectors are considered. For drug discovery, two different complementary approaches can be applied: classical pharmacology, also known as phenotypic drug discovery, which is the historical basis of drug discovery, and reverse pharmacology, also designated target-based drug discovery. Screening methods based on phenotypic drug discovery have been used to discover new natural products mainly from terrestrial origin. Examples of the discovery of marine natural products are provided. A section on future trends provides a comprehensive overview on recent advances that will foster the pharmaceutical industry.

The gastrointestinal microbiota plays a critical role on host health and metabolism. This is particularly important in teleost nutrition, because fish do not possess some of the necessary enzymes to cope with the dietary challenges of aquaculture production. A main difficulty within fish nutrition is its dependence on fish meal, an unsustainable commodity and a source of organic pollutants. The most obvious sustainable alternatives to fish meal are plant feedstuffs, but their nutritive value is limited by the presence of high levels of non-starch polysaccharides (NSP), which are not metabolized by fish. The composition of fish-gut microbial communities have been demonstrated to adapt when the host is fed different ingredients. Thus, we hypothesized that a selective pressure of plant-based diets on fish gut microbiota, could be a beneficial strategy for an enrichment of bacteria with a secretome able to mobilize dietary NSP. By targeting bacterial sporulating isolates with diverse carbohydrase activities from the gut of European sea bass, we have obtained isolates with high probiotic potential. By inferring the adaptive fitness to the fish gut and the amenability to industrial processing, we identified the best two candidates to become industrially valuable probiotics. This potential was confirmed in vivo , since one of the select isolates lead to a better growth and feed utilization efficiency in fish fed probiotic-supplemented plant-based diets, thus contributing for sustainable and more cost-effective aquaculture practices.

This study aimed to produce adjusted normative data for the Portuguese version of the Auditory Verbal Learning Test (AVLT). The study included 1,068 community-dwelling individuals (736 women, 332 men) aged 18 to 93 years old (Mage = 56 years, SD = 18) who had educational backgrounds ranging from 0 to 24 years (M = 9.8 years, SD = 5.3). The results showed that sex, age, and education were significantly associated with AVLT performance. These demographic characteristics accounted for 24% to 35% of the variance of direct recall trials and for 8% to 39% of the variance of derived recall scores. The normative data for direct and derived recall scores are presented as regression-based algorithms to adjust for sex, age, and education with subsequent correspondence between adjusted scores and percentile distribution. The norms for the recognition correct score are presented as algorithms to estimate the recognition scores for 5th, 10th, and 18th percentiles for each combination of the variables sex, age, and education.

Abstract This study aimed to assess diagnosis of Unique Health System (SUS) users profile with regard to herbal medicine. This is a cross-sectional study with observational data collection conducted in the city of Marechal Deodoro, through a semi-structured questionnaire with questions related to socioeconomic data, use, and knowledge of medicinal plants and herbal medicines and satisfaction with the use of medicinal herbs (MH) and interactions of phytotherapeutic drugs (PD). Among the topics, 86.89% of users used herbal medicines often, especially lemon balm (Melissa officinalis L.). It was also observed that the plants are generally used as a sedative (21.74%) and as tea (87.84%). 82.32% of respondents claim to have acquired the knowledge of herbal medicine through a family member and 85.36% make use of medicinal plants without having received any information on the use of MH and PD. 61% of the plants described that coincided with the form of use and therapeutic properties found in the literature. With regard to satisfaction by treatment with MH and PD, it was found that 56.67% are satisfied. Therefore, it is necessary to pay attention to this aspect of usage, in order to avoid possible drug interactions or adverse reactions resulting from the incorrect use.
