Polysyncraton Nott, 1892 is the second largest genus of didemnid ascidians; it has a wide distribution ranging from temperate to tropical waters. Seventy-one specimens of Polysyncraton from eight museum collections and recently collected samples were analyzed. This resulted in the description of three new species (P. cabofriense Oliveira & Rocha sp. nov. from Brazil, P. globosum Oliveira & Rocha sp. nov. from Australia and P. snelliusi Oliveira & Rocha sp. nov. from Suriname) and emended descriptions of three further species (P. amethysteum (Van Name, 1902), P. magnilarvum (Millar, 1962) and P. purou C. Monniot & F. Monniot, 1987).

vestigated processes. In fact, strong evidence suggests that PD begins with an inflammatory process; currently, however, no anti-inflammatory therapy is clinically employed to alleviate the typical motor and the prodromal disturbances such as olfactory loss, cognitive impairments, depression and anxiety, sleep disturbances, and autonomic disorders. In fact, the classical dopaminergic therapies are not effective in alleviating these symptoms and there is no other specific therapy for these outcomes. Therefore, in this review, we will discuss novel potential pharmacological therapeutic strategies focusing on cannabinoids, caffeine, melatonin, and dietary compounds, which could act as adjuvants to regular PD therapy. These described chemicals have been extensively investigated as anti-inflammatory agents possibly promoting beneficial effects on nonmotor symptoms of PD. The investigation of the inflammatory process at different stages of PD progression should give us a better view of the therapeutic scenario and could improve our understanding of the mechanisms of this disease....

Coconut trees of the cv. Green Dwarf of Jiqui in Bahia, northeastern Brazil, that displayed hartrot symptoms were cut and inspected for the presence of insect vectors in the leaf axils. Eggs, nymphs and adults of Lincus lobuliger Breddin (Hemiptera: Pentatomidae), vector of the protozoan causing hartrot, were collected together with an abundance of adults of the predatory beetle Hololepta (Leionata) quadridentada (Olivier) (Coleoptera: Histeridae). In the field, both were placed in a plastic container for transport, and the predation of L. lobuliger eggs by the histerid was observed. The predation was subsequently confirmed under controlled laboratory conditions. Here, we report for the first time H. quadridentada preying on L. lobuliger eggs, suggesting that the histerid contributes to the natural biological control of this vector. Moreover, our results could contribute to the development of biologically sound control strategies against L. lobuliger or other Lincus species.

Nowadays, smartphones represent an invaluable tool to access educational material; however, the available information is not always accurate or evidence-based. Therefore, we aimed to evaluate the use of technology by medical students and assess the effect of a newly developed mobile app for the study of human physiology. We used a standardised questionnaire to assess the profile of educational technology use, from which a mobile app (PhysioQuiz) was developed. The effectiveness and user opinion were assessed in a randomised controlled study (n = 110). Of 1022 students enrolled in medical school, 489 (47.9%) participated in the study. Of the respondents, 96.7% used mobile applications, with the main purpose being entertainment (94.7%) and study (81.9%). Only 6.1% reported use of physiology apps. PhysioQuiz use did not yield higher average grades (p = 0.48); however, user opinion demonstrated that it was useful for assisted learning (82.1%) and identification of non-learned content (78.6%) and considered a tool for self-assessment (89.3%). Mobile app use is widespread among medical students but there is a lack of human physiology education apps. A newly developed app for the study of human physiology was useful for assisted learning and considered a tool for self-assessment.

Recent efforts have been taken to survey and describe the ascidian fauna of the Pacific and Atlantic coasts of Panama; however, the genus Pyura still remains poorly known. Sampling events have been occurring since 2003. In this research, we describe two new species from the Atlantic coast of Panama: P. longispina sp. nov., P. lopezlegentilae sp. nov., and two new species from the Pacific Coast of Panama: P. carmanae sp. nov . and P. imesa sp. nov. We also supply a tabular key for all the Pyura species found in Panama.

The genus Pyura is widely distributed with 99 valid species. Since 1961, Pyura vittata (Stimpson, 1852) has been reported to the Southwest Atlantic but new collections and a revision of the morphological characters of samples deposited in scientific collections revealed that samples had been confused with two other species: Pyura gangelion (Savigny, 1816) and Pyura beta sp. nov. present in the Caribbean sea and Brazil. In Brazil, P. vittata is not present south to Bahia, P. beta was found from Espírito Santo to São Paulo, while P. gangelion was only found in Espírito Santo, and we suggest that populations of both P. beta and P. gangelion are non-native in Brazil.

Clustering methods are essential to partitioning biological samples being useful to minimize the information complexity in large datasets. Tools in this context usually generates data with greed algorithms that solves some Data Mining difficulties which can degrade biological relevant information during the clustering process. The lack of standardization of metrics and consistent bases also raises questions about the clustering efficiency of some methods. Benchmarks are needed to explore the full potential of clustering methods - in which alignment-free methods stand out - and the good choice of dataset makes it essentials. Here we present a new approach to Data Mining in large protein sequences datasets, the Rapid Alignment Free Tool for Sequences Similarity Search to Groups (RAFTS3G), a method to clustering aiming of losing less biological information in the processes of generation groups. The strategy developed in our algorithm is optimized to be more astringent which reflects increase in accuracy and sensitivity in the generation of clusters in a wide range of similarity. RAFTS3G is the better choice compared to three main methods when the user wants more reliable result even ignoring the ideal threshold to clustering. In general, RAFTS3G is able to group up to millions of biological sequences into large datasets, which is a remarkable option of efficiency in clustering. RAFTS3G compared to other “standard-gold” methods in the clustering of large biological data maintains the balance between the reduction of biological information redundancy and the creation of consistent groups. We bring the binary search concept applied to grouped sequences which shows maintaining sensitivity/accuracy relation and up to minimize the time of data generated with RAFTS3G process.
