Enviromental temperature and age of seeds in tolerance to thermoinhibition in lettuce genotypes1

ABSTRACT Lettuce seeds usually show germination problems that can be related to dormancy and or thermoinhibition, as well as to the genotype constitution. The knowledge of the temperature at which the thermoinhibition process begins, as well as the influence of the age of the seed on its germination, is extremely important to establish more suitable parameters for the selection of higher genotypes in breeding programs. The objective of this work was to evaluate the seed germination of three lettuce cultivars according to the enviromental temperature and the age of the seeds. The cultivars Everglades (tolerant to thermoinhibition), Luisa (medium tolerant) and Verônica (sensitive) were used. Seeds of each cultivar were evaluated by the standard germination test, first count test, germination speed index and germination test of remaining seeds. The analyses were performed at four environmental temperatures and in seven storage periods after harvest. None of the cultivars showed primary dormancy. The tolerance to thermoinhibition showed by cultivars Everglades and Luisa and the sensitivity of cultivar Verônica were confirmed. The most suitable temperature for differentiating tolerant and sensitive thermoinhibition genotypes occurred from 30.5 ºC and 260 days after harvest

Cause-specific mortality for 249 causes in Brazil and states during 1990–2015 : a systematic analysis for the global burden of disease study 2015

Background: Reliable data on cause of death (COD) are fundamental for planning and resource allocation priorities. We used GBD 2015 estimates to examine levels and trends for the leading causes of death in Brazil from 1990 to 2015. Methods: We describe the main analytical approaches focused on both overall and specific causes of death for Brazil and Brazilian states. Results: There was an overall improvement in life expectancy at birth from 1990 to 2015, but with important heterogeneity among states. Reduced mortality due to diarrhea, lower respiratory infections, and other infectious diseases contributed the most for increasing life expectancy in most states from the North and Northeast regions. Reduced mortality due to cardiovascular diseases was the highest contributor in the South, Southeast, and Center West regions. However, among men, intentional injuries reduced life expectancy in 17 out of 27 states. Although age-standardized rates due to ischemic heart disease (IHD) and cerebrovascular disease declined over time, these remained the leading CODs in the country and states. In contrast, leading causes of premature mortality changed substantially - e.g., diarrheal diseases moved from 1st to 13th and then the 36th position in 1990, 2005, and 2015, respectively, while violence moved from 7th to 1st and to 2nd. Overall, the total age-standardized years of life lost (YLL) rate was reduced from 1990 to 2015, bringing the burden of premature deaths closer to expected rates given the country’s Socio-demographic Index (SDI). In 1990, IHD, stroke, diarrhea, neonatal preterm birth complications, road injury, and violence had ratios higher than the expected, while in 2015 only violence was higher, overall and in all states, according to the SDI. Conclusions: A widespread reduction of mortality levels occurred in Brazil from 1990 to 2015, particularly among children under 5 years old. Major shifts in mortality rates took place among communicable, maternal, neonatal, and nutritional disorders. The mortality profile has shifted to older ages with increases in non-communicable diseases as well as premature deaths due to violence. Policymakers should address health interventions accordingly

Abordagens clínicas da doença do refluxo gastroesofágico no âmbito atual: uma revisão de literatura

A Doença do Refluxo Gastroesofágico (DRGE) pode ser definida como uma condição na qual o retorno do conteúdo gástrico para o esôfago desencadeia sintomas incômodos e/ou complicações (BARREIRO,B.A e et al., 2023). Ademais, a DRGE é uma das afecções digestivas mais incidentes, cerca de 20% dos adultos nos países ocidentais e aproximadamente 5% dos asiáticos são portadores da doença e a prevalência anual dos sintomas vem aumentando por volta de 4% (BARREIRO, B.A et al., 2023). Logo, este artigo tem como objetivo analisar as abordagens clinicas da doenca do refluxo gastroesofágico no âmbito atual. Dessa forma, este estudo configura-se como uma revisão integrativa realizada por meio do levantamento bibliográfico nos diretórios: Google Scholare Scientific Eletronic LibraryOn-line (SciELO). Desta busca, foram selecionados artigos entre os anos 2021 e 2023, posteriormente submetidos aos critérios de seleção. A doença do refluxo gastroesofágico está associada a uma probabilidade 5 a 7 vezes maior de desenvolver adenocarcinoma esofágico e 60% dos pacientes com câncer relatam história de DRGE. O esôfago de Barrett é uma adaptação metaplásica das células esofágicas em que a mucosa do tipo intestinal substitui a mucosa escamosa normal. Cerca de 15% dos pacientes com DRGE desenvolvem esôfago de Barret. Contínuo a isso, os tratamento mais comuns utilizados na pratica clinica são medidas não farmacológicas como dieta, sono e fitoterapia e farmacológicas como inibidores da bomba de prótons (IBPS), bloqueadores de H2 e procinéticos. Dessa forma, conclui-se que, embora a supressão ácida seja bem-sucedida no tratamento da DRGE, não parece haver uma relação clara entre a gravidade da DRGE e os níveis elevados de ácido gástrico. Ademais, a junção do tratamento farmacológico com o não farmacológico se mostrou superior a abordagem destes de forma isolada

A retrospective investigation was undertaken to describe clinical, epidemiological, and viral genomic features associated with deaths caused by CHIKV in Ceará state, northeast Brazil. METHODS: Sera, cerebrospinal fluid (CSF), and tissue samples from 100 fatal cases with suspected arbovirus infection were tested for CHIKV, dengue virus (DENV), and Zika virus (ZIKV). Clinical, epidemiological, and death reports were obtained for patients with confirmed CHIKV infection. Logistic regression analysis was undertaken to identify independent factors associated with risk of death during CHIKV infection. Phylogenetic analysis was conducted using whole genomes from a subset of cases. RESULTS: Sixty-eight fatal cases had CHIKV infection confirmed by reverse-transcription quantitative polymerase chain reaction (52.9%), viral antigen (41.1%), and/or specific immunoglobulin M (63.2%). Co-detection of CHIKV with DENV was found in 22% of fatal cases, ZIKV in 2.9%, and DENV and ZIKV in 1.5%. A total of 39 CHIKV deaths presented with neurological signs and symptoms, and CHIKV-RNA was found in the CSF of 92.3% of these patients. Fatal outcomes were associated with irreversible multiple organ dysfunction syndrome. Patients with diabetes appear to die at a higher frequency during the subacute phase. Genetic analysis showed circulation of 2 CHIKV East-Central-South African (ECSA) lineages in Ceará and revealed no unique virus genomic mutation associated with fatal outcome. CONCLUSIONS: The investigation of the largest cross-sectional cohort of CHIKV deaths to date reveals that CHIKV-ECSA strains can cause death in individuals from both risk and nonrisk groups, including young adults. © The Author(s) 2020.
