1. Chromatographic Profiles of Ethyl Acetate Extracts Produced by Bacillus sp. Collected from the Mangroves in the Brazilian Northeast
The genus Bacillus is Gram-positive, anaerobic or aerobic facultative bacteria, often described to be associated with the mangrove rhizosphere. Secondary products of their metabolism, coming from places affected by pollution and environmental stresses, such as mangroves, have been attracting interest from the biotechnological point of view. In view of this s

2. Type 2 diabetes mellitus-related environmental factors and the gut microbiota: emerging evidence and challenges
The gut microbiota is a group of over 38 trillion bacterial cells in the human microbiota that plays an important role in the regulation of human metabolism through its symbiotic relationship with the host. Changes in the gut microbial ecosystem are associated with increased susceptibility to metabolic disease in humans. However, the composition of the gut m

3. Anthropogenic impacts on aquatic bacteria: a perspective from the tropics
Resumo O bacterioplâncton compreende um grupo altamente diversificado de microrganismos, que são dominantes nos ecossistemas aquáticos e desempenham um papel central no funcionamento desses ecossistemas e nos ciclos biogeoquímicos. Devido às suas elevadas taxas de dispersão e de mudança na composição, bem como alta adaptabilidade e plasticidade, os

4. The structuring role of macrophytes on plankton community composition and bacterial metabolism in a large subtropical shallow lake
Resumo Objetivo Nós objetivamos investigar mudanças nos principais grupos do plâncton (bacterioplâncton, fitoplâncton e zooplâncton) e no metabolismo do bacterioplâncton ao longo de um transecto cobrindo uma zona litorânea dominada por macrófitas para uma zona pelágica dominada por fitoplâncton na lagoa Mangueira, uma lagoa extensa, rasa e subtro

5. Periapical bone response to bacterial lipopolysaccharide is shifted upon cyclooxygenase blockage
Abstract Objectives: Infection, inflammation and bone resorption are closely related events in apical periodontitis development. Therefore, we sought to investigate the role of cyclooxygenase (COX) in osteoclastogenesis and bone metabolism signaling in periapical bone tissue after bacterial lipopolysaccharide (LPS) inoculation into root canals.

6. Micronutrients: Speculation on Inborn Errors, Nutrigenomics, Evolution, the Microbiome, and Nutritional Immunity
Abstract Many micronutrients or cofactors derived from micronutrients are highly reactive, hence their role in catalysis of reactions by enzymes. The concentration of cofactors has to be kept low to avoid unwanted reactions while allowing them to bind to the (apo)enzymes that need them. A new disorder causing B6-responsive epilepsy (proline synthetase cotran

7. Trichoderma harzianum MTCC 5179 impacts the population and functional dynamics of microbial community in the rhizosphere of black pepper (Piper nigrum L.)
Abstract Employing Illumina Hiseq whole genome metagenome sequencing approach, we studied the impact of Trichoderma harzianum on altering the microbial community and its functional dynamics in the rhizhosphere soil of black pepper (Piper nigrum L.). The metagenomic datasets from the rhizosphere with (treatment) and without (control) T. harzianum inoculation

8. Relationships between female infertility and female genital infections and pelvic inflammatory disease: a population-based nested controlled study
OBJECTIVES: Our purpose was to examine the associations of female genital infections and certain comorbidities with infertility. METHODS: The Taiwan National Health Research Database was searched for women with a new diagnosis of infertility between 2000 and 2013. Women without a diagnosis of infertility served as a control group and were matched with the

9. Biological Synthesis of Selenium Nanoparticles and Evaluation of their Bioavailability
ABSTRACT Nanoparticles due to their unique properties have attracted more attention and their bacterial biosynthesis is more favorable because is environmental friendly and the size and yield of nanoparticles can be optimized. The aim of the present study was biosynthesis of Selenium nanoparticles using Bacillus cereus. For this purpose, bacterial culture wa

10. Fast detection of Mycobacterium tuberculosis in culture-positive sputum samples by nitrate reductase activity
ABSTRACT Microscopy and bacterial culture are the main tools in the diagnosis of tuberculosis. Since the slow growth of Mycobacterium tuberculosis impairs rapid diagnosis strategies, especially in countries where the latter are the only available resources, the ongoing development of new and inexpensive tools based on mycobacterial metabolism optimizing grow

11. Evaluation of E. coli inhibition by plain and polymer-coated silver nanoparticles
ABSTRACT Escherichia coli causes various ailments such as septicemia, enteritis, foodborne illnesses, and urinary tract infections which are of concern in the public health field due to antibiotic resistance. Silver nanoparticles (AgNP) are known for their biocompatibility and antibacterial activity, and may prove to be an alternative method of treatment, es

12. Comparison of Gut Microbial Diversity in Beijing Oil and Arbor Acres Chickens
ABSTRACT The Beijing oil (BJO) chicken is an autochthona Chinese breed which shows outstanding meat quality characteristics compared with fast-growing imported chickens such as Arbor Acres (AA) chickens. Gut microbial diversity has been shown to influence host factors such as energy and nutrient metabolism, immune response and fertility. Consequently, it is
