Doses de fósforo em híbridos de milho cultivados em solo arenoso

O objetivo da pesquisa é analisar doses crescentes de adubação fosfatada em dois diferentes híbridos de milho cultivados em solo arenoso. O delineamento experimental foi de blocos casualizados, em esquema fatorial 2 x 5, sendo dois híbridos de milho (Brevant 688 e Agroceres 1051) e cinco doses de fósforo (0; 50; 100; 150 e 200 kg ha-1 de P2O5), replicadas quatro vezes. A fonte de fósforo utilizada foi o monofosfato de amônio. O solo utilizado foi coletado de um Neossolo Quartzarênico com 903 g kg-1 de areia. Aos 45 dias após o plantio dos híbridos foram mensuradas as características estruturais como altura de plantas e o diâmetro de colmo. A biomassa vegetal foi pesada e seca para a obtenção dos dados que foram submetidos à análise de variância e estudo de regressão. As plantas híbridas de milho diferem em suas respostas à aplicação de fósforo em solo de textura arenosa, indicando a necessidade de diferentes recomendações de adubação fosfatada no mesmo solo para diferentes híbridos, sendo que para o genótipo Brevant 688 ocorreram as maiores produções indicando maior potencial para a utilização desse material para as condições de textura extremas impostas neste estudo

Terapia do par biomagnético e Meningite Tuberculosa: um relato de caso: Biomagnetic pair therapy and Tuberculous Meningitis: a case report

A terapia do Par Biomagnético (PB) visa tratar a causa das doenças através do uso das duas polaridades de ímãs de média intensidade colocados sobre o corpo, em pontos específicos, com a finalidade de detectar e corrigir desequilíbrios eletromagnéticos e distorções do potencial hidrogeniônico. Neste relato de caso, foi aplicada a terapia do PB em uma criança diagnosticada com meningite tuberculosa (MTB) que se encontrava em tratamento convencional há quase cinco meses. O paciente queixava-se de dor lancinante e apresentava outros sinais e sintomas neurológicos. Após duas sessões de terapia do PB, foi possível eliminar a dor e constatar melhora no quadro geral

Indoor Dust as a Source of Virulent Strains of the Agents of Cryptococcosis in the Rio Negro Micro-Region of the Brazilian Amazon.

Cryptococcosis, a potentially fatal mycosis in humans, is acquired via exposure to exogenous environmental sources. This study aimed to investigate the frequency, genetic diversity, and virulence of cryptococcal strains isolated from indoor dust in the Rio Negro micro-region of the Brazilian Amazon. A total of 8.9% of the studied houses were positive, recovering nine Cryptococcus neoformans VNI and 16 C. gattii VGII isolates, revealing an endemic pattern in domestic microenvironments. The International Society for Human and Animal Mycology (ISHAM) consensus multilocus sequence typing (MLST) scheme for the C. neoformans/C. gattii species complexes identified two sequence types (STs), ST93 and ST5, amongst C. neoformans isolates and six STs amongst C. gattii isolates, including the Vancouver Island Outbreak ST7 (VGIIa) and ST20 (VGIIb), the Australian ST5, and ST264, ST268 and ST445, being unique to the studied region. Virulence studies in the Galleria mellonella model showed that five C. gattii strains and one C. neoformans strain showed a similar pathogenic potential to the highly virulent Vancouver Island outbreak strain CDR265 (VGIIa). The findings of this study indicate that humans can be exposed to the agents of cryptococcosis via house dust, forming the basis for future studies to analyze the impact of early and continuous exposure to indoor dust on the development of subclinical or clinical infections

Avaliação da qualidade microbiológica de queijos do tipo coalho comercializados em Maceió-AL / Evaluation of the microbiological quality of rennet-type cheeses commercialized in Maceió-AL

O queijo coalho é considerado uma grande iguaria do Nordeste brasileiro, tendo como matéria-prima o leite cru. Produzido na maioria das vezes em pequenas queijarias artesanalmente, sem Boas Práticas de Fabricação, acesso à treinamentos necessários para elaboração de um alimento seguro. Esses fatores podem elevar a carga microbiana do produto final, comprometendo as condições de higiene associadas ao armazenamento e transporte, servindo como meio de cultura para microrganismos diversos, sendo assim, o consumidor sofre o risco de ser exposto à patógenos. Dadas essas circunstâncias, duas marcas comerciais, identificadas como A e B, foram submetidas a estudo para quantificar os coliformes termotolerantes (CTT) e evidenciar a presença de Bacillus cereus, Escherichia Coli e Salmonella sp. Os resultados apresentaram para CTT’s de 6,8x102 NMP/g para ambas, utilizando-se a técnica do Número Mais Provável, também chamada de técnica dos tubos múltiplos. Foi estimada contagem de coliformes totais e termotolerantes, tendo como base a Tabela Estatística de Hoskins para cinco tubos. O valor se mostra acima do limite estabelecido pela legislação brasileira, que define como o máximo permitido de coliformes termotolerantes, o valor de 5,0x102 NMP/g de amostra. Através das provas bioquímicas, por meio do Kit de Teste Bactray I, II e III, da Laborclin, foi constatada presença de E. Coli nas duas marcas e Salmonella sp em uma delas. 

Landscape Transformation: Temporal Evolution of the Erosion Process on a Hillside on the Island of Itamaracá / Brazil

Urban planning is important to guarantee the quality of life for society, as it proposes spatial planning and problem solving, especially those related to land use. Thus, it was proposed to perform an evaluation of actions that promote and/or accelerate the erosive processes on a hillside located in island of Itamaracá/BR. The “interaction networks” and “land use maps” techniques were used in combination, which resulted in a more accurate environmental assessment, as well as the use of models for future estimates. The results pointed to mediumrisk for the environmental indicators of “occupation types” and evidence of collapse”, and high risk for“urban density”and“vegetation”indicators. It has also been predicted that over the years, the urban sprawl in the area will continue to grow until it reaches stability due to the total occupation of useful areas as well as that the growth rate for vegetation will be negative. Thus, there is a need to mitigate environmental damage in the short term, in order to avoid the occurrence of accidents in the hillside area

Characteristics of resistance training-based protocols in older adults with sarcopenic obesity: a scoping review of training procedure recommendations

Background: Sarcopenic obesity (SO) is a clinical and functional disease characterized by the coexistence of obesity and sarcopenia. Resistance training (RT) characteristics for older adults with sarcopenia or obesity are already well established in the scientific literature. Nonetheless, we still do not know how detailed the RT protocols are described for older adults with SO. Therefore, we aimed to analyze the characteristics of RT programs, including each of their variables, recommended for older adults with SO. Methods: This is a scoping review study that was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis for Scoping Reviews. The search was carried out until November 2022 in PubMed/MEDLINE, EMBASE, Cochrane Library, Web of Science, Scopus, LILACS, Google Scholar, and medRxiv databases. The studies included SO diagnosis and RT as an intervention strategy. The RT variables analyzed were as follows: exercise selection, the volume of sets, the intensity of load, repetition cadence, rest interval between sets, and weekly frequency. Results: A total of 1,693 studies were identified. After applying the exclusion criteria, 15 studies were included in the final analysis. The duration of the RT intervention ranged from 8 to 24 weeks. All studies included full-body routines, with single/multi-joint exercises. Regarding the volume of sets, some studies fixed it in three sets, whereas others varied between one and three sets. The load was reported by repetition range and the weight lifted, elastic-band color/resistance, percentage of one repetition maximum, or perceived exertion scale. Repetition cadence was fixed in some studies, while it was self-selected between concentric and eccentric phases in others. The interval between sets of rest varied from 30 to 180 s. All studies reported progression overload during the interventions.info:eu-repo/semantics/publishedVersio

Impact of Si on C, N, and P stoichiometric homeostasis favors nutrition and stem dry mass accumulation in sugarcane cultivated in tropical soils with different water regimes

Studies with silicon (Si) in sugarcane indicate a greater response in productivity in plants under stress, and the underlying mechanisms of Si in the crop are poorly reported. In this context, the benefits of Si in the crop’s stem production are expected to occur at the C:N:P stoichiometry level in plant tissues, benefiting plants with and without stress. However, the extension of this response may vary in different soils. Thus, this research aimed to evaluate if fertigation with Si modifies the C:N:P stoichiometry and if it can increase sugarcane’s nutritional efficiency and vegetative and productive parameters. Therefore, three experiments were installed using pre-sprouted seedlings to cultivate sugarcane in tropical soils belonging to the Quartzarenic Neosol, Eutrophic Red Latosol, and Dystrophic Red Latosol classes. The treatments comprised a 2 × 2 factorial scheme in each soil. The first factor was composed without water restriction (water retention = 70%; AWD) and with water restriction (water retention = 35%; PWD). The second factor presented Si concentrations (0 mM and 1.8 mM) arranged in randomized blocks with five replications. Fertigation with Si increases the Si and P concentration, the C and N efficiency, the C:N ratio, and the dry mass production. However, it decreases the C and N concentration and the C:P, C:Si, and N:P ratios in sugarcane leaves and stems regardless of the water regime adopted in the three tropical soils. Cluster and principal components analysis indicated that the intensity of the beneficial effects of Si fertigation on sugarcane plants varies depending on the cultivation soil and water conditions. We found that Si can be used in sugarcane with and without water stress. It changes the C:N:P homeostasis enough to improve the nutritional efficiency of C, P, N, and, consequently, the dry mass accumulation on the stems, with variation in the different cultivated soils
