Distribution of strontium isotopes (Sr/Sr) in surface waters of the Amazon basin: A basis for studies on provenance.

The Sr/Sr isotope ratio has been widely used as an indicator of provenance and migration of aquatic animals, and has applications in other areas such as in environmental and forensic studies. However, the modeling of the spatial distribution in the Amazon basin is still incipient, preventing large-scale applications. In this study, we present a baseline of the Sr/Sr isotope ratio in surface waters of the Amazon basin to infer the provenance and migration patterns of fish.

[Inequalities in the adequacy to consultation calendar for children under 5 years old in the Food and Nutritional Surveillance].

The Ministry of Health recommends a minimum appointment schedule in childcare to monitor growth and development. The objective was to analyze the adequacy of the minimum appointment schedule for children under 5 years of age, with at least one anthropometric follow-up registered with the Food and Nutrition Surveillance System (SISVAN) between 2008 and 2020. The sample size comprised 23,453,620 children under the age of 5, and 103,773,311 records.

Biofilm formation by the plant growth promoting bacterium Bacillus cereus (EB-40).

The objective of this work was to investigate the biofilm production capacity of the isolate EB-40 (Bacillus cereus) in a culture medium for the multiplication of microorganisms and in roots of in vitro grown banana explants. It was observed that the isolate was able to produce biofilms in tryptone, soy and agar (TSA) culture medium and in the roots of explants. The format, architecture and location of the biofilms in TSA culture medium presented an exopolymer matrix formed by EB-40 presented coccoid bacillary cells and fibrillar structures.

Impact of CB1 receptor antagonism on skeletal muscle hypertrophy and metabolic health: a systematic review of preclinical studies.

The endocannabinoid system (ECS), regulating such processes as energy homeostasis, inflammation, and muscle function, centers around cannabinoid receptors, including CB1. These receptors are mainly located in the central nervous system and skeletal muscles. Hyperactivity of CB1 receptors is linked to metabolic disorders and chronic inflammation, highlighting their potential as therapeutic targets for muscle hypertrophy and metabolic health.

Neuropsychiatric manifestations in systemic lupus erythematosus and Sjogren's disease.

Introduction: Autoimmune diseases often present in a systemic manner, affecting various organs and tissues. Involvement of the central and peripheral nervous system is not uncommon in these conditions and is associated with high morbidity and mortality. Therefore, early recognition of the neuropsychiatric manifestations associated with rheumatologic diseases is essential for the introduction of appropriate therapies with the objective of providing a better quality of life for individuals.
