Background: Preeclampsia is a major hypertensive disorder of pregnancy, which may lead to severe complications, particularly in the first two weeks of the postpartum period. During the postpartum period, blood pressure levels remain high, often increasing to levels higher than those experienced during pregnancy. Furosemide, a fast-acting diuretic, reduces the intravascular volume overload and may represent an alternative to accelerate the normalization of blood pressure levels.

Growing evidence of the benefits of home ventilatory support in patients with chronic respiratory failure along with technological advances in ventilators have enabled their use in overly complex situations, shaping a new scenario for physicians. This has further given rise to new challenges related to their incorporation into current medical practice. However, this evolution needs to be coupled with knowledge and skills of physicians who are willing to prescribe Home Mechanical Ventilation (HMV), in order to prevent them from making inappropriate choices or adjustments that may ultimately have ethical and legal implications.

Elucidating the pathogenicity of Metarhizium to Euschistus heros (Hemiptera: Pentatomidae) eggs.

Department of Entomology and Acarology, Escola Superior de Agricultura 'Luiz de Queiroz', University of São Paulo (ESALQ-USP), Av. Pádua Dias, 11, Piracicaba, SP CEP 13418-900, Brazil.

The ovicidal effect of entomopathogenic fungi and the mechanisms involved are still debated. The hypothesis that the metabolic activity of germinating conidia can cause insect embryos to become unviable without physical penetration has been proposed. Here, we demonstrated that Metarhizium anisopliae and Metarhizium pingshaense, differently from Beauveria bassiana, reduced the percentage of nymphs hatching to less than 3%.

Tyramine, β-phenylethylamine, octopamine and other trace amines are endogenous substances recently recognized as important novel neurotransmitters in the brain. Trace amines act via multiple selective trace amine-associated receptors (TAARs) of the G protein-coupled receptor family. TAARs are expressed in various brain regions and modulate neurotransmission, neuronal excitability, adult neurogenesis, cognition, mood, locomotor activity and olfaction.

Dithranol is one of the most effective topical medications for treating plaque psoriasis. However, its clinical use is limited by irritative adverse reactions to the skin, such as oedema, erythema, and pruritus, caused by poorly understood mechanisms. Because TRPV1 activation mediates skin irritation caused by several drugs, we conducted blind and randomised experiments in male and female C57BL/6 mice to elucidate the role of TRPV1 in dithranol-induced irritation.

Fear generalization, a lack of discrimination between safe and unsafe cues, is a hallmark of posttraumatic stress disorder. The phosphodiesterase 5 (PDE5) regulates the cyclic guanosine monophosphate (cGMP) pathway, which has been proposed to be involved in fear memory generalization. However, whether PDE5 activity underlies fear memory generalization remains unexplored.

The biotransformation of compounds is a critical point in understanding their toxic effects in both toxicology and ecotoxicology. The objective of this study was to evaluate whether there is a difference in the phytogenotoxic potential of the commercial fungicide Nativo® between non-biotransformed samples and samples biotransformed by swine liver enzymes. The fungicide Nativo is a mixture of Tebuconazole (TEB; 200 g L) and Trifloxystrobin (TRI; 100 g L).

In this work, we investigate the dynamics of a discrete-time prey-predator model considering a prey reproductive response as a function of the predation risk, with the prey population growth factor governed by two parameters. The system can evolve toward scenarios of mutual or only of predators extinction, or species coexistence. We analytically show all different types of equilibrium points depending on the ranges of growth parameters.

Melatonin is a pineal hormone synthesized exclusively at night, in several organisms. Its action on sperm is of particular interest, since they transfer genetic and epigenetic information to the offspring, including microRNAs, configuring a mechanism of paternal epigenetic inheritance. MicroRNAs are known to participate in a wide variety of mechanisms in basically all cells and tissues, including the brain and the sperm cells, which are known, respectively, to present 70% of all identified microRNAs and to transfer these molecules to the embryo.

Angiotensin II (Ang II) is the most active peptide hormone produced by the renin-angiotensin system (RAS). Genetic deletion of genes that ultimately restrict Ang II formation has been shown to result in marked anemia in mice. In this study, adult mice with a genetic deletion of the RAS precursor protein angiotensinogen (Agt-KO) were used.

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.

Programa de Pós-Graduação em Ciências Biológicas: Bioquímica, Instituto de Ciências Básicas da Saúde, Universidade Federal do Rio Grande do Sul, Porto Alegre, RS, Brazil.

Resveratrol, a natural polyphenol, has shown promising neuroprotective effects in several in vivo and in vitro experimental models. However, the mechanisms by which resveratrol mediates these effects are not fully understood. Glutamate is the major excitatory neurotransmitter in the brain; however, excessive extracellular glutamate levels can affect neural activity in several neurological diseases.

The biochemical composition of sediments, which depends on the origin of the organic matter (OM), is decisive in methane (CH) production. This study aimed to determine the CH produced under anaerobic conditions from different substrates: native reservoir sediments and sediments with the addition of complex OM from Microcystis spp. blooms and terrestrial plants (pasture), alongside the biochemical characterization of the substrates used.
