Physiological quality of pink pepper seeds (Schinus terebinthifolia Raddi.) as a function of storage

Seeds of native forest species for food and seedling production have a growing demand that impacts the need for studies involving seed storage in order to maintain good levels of germination quality. Thus, scientific analyzes that explore the physiological potential of the seeds of these species are necessary, especially for the pink pepper (Schinus terebinthifolia Raddi.), a species used as an alternative source of income for traditional communities and which has been arousing interest due to the consumption of its fruits as a condiment in the national and international market. This work aimed to assess the physiological quality of pink pepper seeds according to the storage period and seed size. The seeds came from a rural settlement, a pioneer in the extraction of pink pepper, in the state of Rio de Janeiro, Brazil. The seeds were evaluated for moisture content, germination, first count, length and dry weight of the germinated seedlings, during the period of time that they remained stored and the size of the seeds. The results allowed to conclude that: i) the germinative percentage of the stored pink pepper seeds decreased over the months; ii) the moisture content of the seeds decreased over the months evaluated iii) the different sizes of seeds did not show differences in germination and storage time and iv) values of length and dry weight of the seedlings did not differ according to the period of storage

Transtorno bipolar em crianças: análise de relato de caso 2018-2023

O transtorno bipolar em crianças é uma realidade clínica que demanda atenção especializada. A compreensão dos sintomas, fatores de risco, prevalência e desafios diagnósticos é fundamental para proporcionar intervenções precoces e adequadas, visando melhorar a qualidade de vida desses jovens e reduzir o impacto a longo prazo dessa condição psiquiátrica. Trata-se de um estudo cujo objetivo foi objetivo revisar relatos de caso publicados entre 2018 e 2023 sobre transtorno bipolar em crianças, identificando o estado da arte desses estudos. Para isso, se realizou uma revisão sistemática de literatura utilizando as bases de dados Medical Literature Analysis and Retrieval System Online (MEDLINE), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) e Scientific Electronic Library Online (SCIELO). Com a análise e interpretação qualitativa dos resultados, a principal conclusão deste estudo é que o transtorno bipolar na infância é uma condição complexa, manifestando-se com comportamentos consistentes com o Transtorno de Conduta e sendo influenciado por fatores ambientais, familiares e genéticos. O tratamento eficaz requer uma abordagem multidisciplinar, integrando intervenções farmacológicas e não farmacológicas, personalizadas conforme as necessidades individuais. A supervisão familiar é crucial para a adesão ao tratamento, mas reconhece-se a necessidade contínua de pesquisa para aprimorar as estratégias terapêuticas diante da diversidade de casos

Así, son necesarios análisis científicos que exploren el potencial fisiológico de las semillas de estas especies, especialmente para la pimienta-rosa (Schinus terebinthifolia Raddi), especie utilizada como fuente alternativa de ingresos para las comunidades tradicionales y que ha despertado interés por la consumo de sus frutos como condimento en el mercado nacional e internacional. Este trabajo tuvo como objetivo evaluar la calidad fisiológica de las semillas de pimienta-rosa según el período de almacenamiento y el tamaño de la semilla. Las semillas provienen de un asentamiento rural, pionero en la extracción de pimienta rosa, en el estado de Río de Janeiro, Brasil. Las semillas fueron evaluadas por contenido de humedad, germinación, primer conteo, longitud y peso seco de las plántulas germinadas, durante el período de tiempo que permanecieron almacenadas y el tamaño de las semillas. Los resultados permitieron concluir que: i) el porcentaje germinativo de las semillas de pimienta-rosa almacenadas disminuyó a lo largo de los meses; ii) el contenido de humedad disminuyó durante los meses evaluados; iii) los diferentes tamaños de semilla no mostraron diferencias en la germinación y el tiempo de almacenamiento y iv) los valores de longitud y peso seco de las plántulas no difirieron según el período de almacenamiento
