Physical, physicochemical and taxonomic characterization of Psidium araça Raddi

New research has stimulated a large reevaluation of species with regards to the use of fruits from native plants. Araçá (a small Brazilian guava-like fruit) is found scattered in the wild in Pernambuco/Brazil. There is a scarcity of detailed studies on such regional fruit trees, especially the Psidium araçá Raddi species, whereas there is an enormous possibility to explore the potential offered by these fruits, such as in the field of gastronomy, where the search for new ingredients and exotic flavors associated with functional properties has been increasing. This article aimed to evaluate the physical, physicochemical and taxonomic characterization of araçá obtained from different agricultural regions of Pernambuco in order to investigate the possibility of developing new products from this native fruit. The taxonomic identification confirmed that all collected material belonged to the species P. araçá Raddi. An average weight of 7.45 g/fruit was observed. With respect to pH, values between 3.17 and 3.48 were found, and the acidity as a percentage of citric acid was on the order of 0.96% to 0.99%. It was shown that the P. araçá Raddi fruit has a desirable quality for the food industry, presenting excellent conditions for the development of formulations of high commercial value and promising application in the national gastronomy

The presence of depressive symptoms and cognitive performance among older individuals with and without self-reported chronic diseases

ABSTRACT. Dementias secondary to cardiovascular diseases are the second cause of neurogenerative diseases. These conditions can be prevented by controlling risk factors, and it is necessary to observe the relationship between chronic diseases. Objective: to know the influence of chronic non-communicable diseases on cognition and depressive symptoms in the elderly, amid the COVID-19 pandemic. Methods: 578 older adults were evaluated using a sociodemographic questionnaire, the Brazilian Telephone version of the Mini Mental State Examination (Braztel-MMSE), the Geriatric Depression Scale (GDS-15) and an open questionnaire related to NCDs. Results: the association of Non-Communicable Diseases (NCD) with age, depressive symptoms and schooling was confirmed. Conclusion: no association with cognitive decline was evident due to the relationship of high schooling of participants and control of NCDs

BALB/c Mice Infected with Antimony Treatment Refractory Isolate of Leishmania braziliensis Present Severe Lesions due to IL-4 Production

Leishmaniasis is a neglected disease that affects more than 12 million people worldwide. In Brazil, the cutaneous disease is more prevalent with about 28,000 new cases reported each year, and L. braziliensis is the main causative agent. The interesting data about the infection with this parasite is the wide variety of clinical manifestations that ranges from single ulcerated lesions to mucocutaneous and disseminated disease. However, experimental models to study the infection with this parasite are difficult to develop due to high resistance of most mouse strains to the infection, and the mechanisms underlying the distinct manifestations remain poorly understood. Here, the authors use a mouse experimental model of infection with different L. braziliensis isolates, known to induce diseases with distinct severity in the human hosts, to elucidate immune mechanisms that may be involved in the different manifestations. They showed that distinct parasite isolates may modulate host response, and increased IL-4 production and Arg I expression was related to more severe disease, resulting in longer length of disease with larger lesions and reduced parasite clearance. These findings may be useful in the identification of immunological targets to control L. braziliensis infection and potential clinical markers of disease progression

Cacos de uma história: reconstituição das vasilhas guarani

The restoration of broken pottery vessels, of archaeological value, it has been a practice of the Laboratory of Archaeology Guarani FCT/ UNESP, since 1988. This practice aims for exhibition in museums, pieces that were in boxes in the technical reserves of museums, intended for ignorance. This activity assists in the exhibition of collections and thus enables disclose the history of Indians who lived in our area and now can no longer tell their stories through words. The screen in outreach activity is held with the support of PROEX to museums in the state of São Paulo, for free.O restauro de vasilhas cerâmicas quebradas, de valor arqueológico, tem sido uma prática do Laboratório de Arqueologia Guarani da FCT/UNESP, desde 1988. Essa prática visa colocar em exposição de museus, peças que antes estavam em caixas nas reservas técnicas dos museus e, assim, destinadas ao desconhecimento. Essa atividade auxilia na exposição de acervos e, dessa forma, possibilita divulgar a história de índios que viveram na nossa região e que hoje já não podem contar as suas histórias por meio de palavras. A atividade de extensão em tela é realizada com apoio da PROEX para museus do Estado de São Paulo, de forma gratuita
