AbstractThe objective of the study was to characterize immunological responses to a Brazilian Jiu-Jitsu high-intensity interval training session. Neuromuscular function, blood, and salivary samples were obtained after a Brazilian Jiu-Jitsu high-intensity interval training session. Saliva and blood samples were collected at Pre- (before the warm-up) and immediately Post-training. Neuromuscular function was evaluated by lower body muscle testing. The horizontal countermovement jump was performed at Pre (after the warm-up) and immediately Post blood and saliva collection, and approximately 5 minutes Post-training. The horizontal countermovement jump performance did not present any significant changes Post-training, while blood leukocytes, urea, IgA and salivary alpha-amylase showed a significant increase. Salivary alpha-amylase activity increased more than six times immediately Post compared to Pre-training. Saliva volume, secretion rate, and uric acid were not significantly different between Pre and Post condition. A Brazilian Jiu-Jitsu high-intensity interval training session elicited an increase in the blood cells responsible for antibody production and muscle damage adaptation after exercise. On the other hand, neuromuscular performance was not significantly affected Post-training, suggesting that immunological and performance responses were not necessarily associated.

Yerba mate (Ilex paraguariensis A. St.-Hil.) is a species of great economic, social and environmental importance for the southern regions of Brazil, Uruguay and Argentina. Currently the most diverse products are obtained from mate leaves, including mate tea. The objective of this study was to establish shoot meristem cultures (meristematic dome and a few primordia) of elite clones and identify the endophytic bacteria present in the explants. We tested the effect of clones (F1, F2, A03 and A07), culture media (MS, 1/2MS, 1/4MS and WPM), cytokinins (kinetin, BA and 2iP), activated charcoal (1, 2 and 3 g L−1), and disinfecting agent (sodium hypochlorite and mercuric chloride) on in vitro establishment. F1 and F2 clones were the most responsive for shoot meristem in vitro culture. WPM medium supplemented with 8.8 µM 2iP, 0.2 µM NAA and 3 g L−1 activated charcoal was the most suitable for the in vitro establishment of the F1 clone. No phytotoxic effect of the disinfectant was observed and some meristems sprouted. The isolated endophytic bacterium was identified for the first time in yerba mate as Agrobacterium larrymoorei. To conclude, we were able to establish in vitro culture of yerba mate using meristems as explants but the tissues were not free of endophytic microorganisms which could interfere with explant response.

Sugarcane is of great economic importance worldwide. Hence, there is great interest in the development of efficient techniques for the production of good quality, homogeneous, disease- and pest-free seedlings. One way to eliminate viruses is through meristem culture. To guarantee success during meristem culture, it is necessary to optimize the components and concentrations of the culture medium. Sucrose is an essential component in the culture medium, serving as a source of carbon and energy for the seedlings. Nitrogen, in turn, is essential in plants because it is a component of biomolecules and countless enzymes. This work evaluates the best combination of nitrogen (75, 100, 125, and 150%) and sucrose (0, 20, 30, and 40 g L-1) concentrations in the in vitro multiplication and development of sugarcane cultivar RB036091. The design was completely randomized, in a factorial scheme with four replicates and five explants per experimental unit. The concentration of 20 g L-1 sucrose with 100% nitrogen, from the original formulation of the MS culture medium, provided a better response in sugarcane multiplication.

Parkinson’s disease (PD) is the second most prevalent neurodegenerative disorder worldwide. Among its non-motor symptoms, sleep disorders are extremely common, being linked to cognitive and memory disruption. The microenvironment, particularly the extracellular matrix (ECM), is deeply involved in memory consolidation as well as in neuropathological processes, such as inflammation, damage to the blood-brain barrier and neuronal death. To better understand ECM dynamics in PD memory disturbances, we investigated the orchestrated expression of Mmps (Mmp-3, Mmp-7, and Mmp-9) and their modulators (Reck and Timp-3) in a rotenone-induced PD model. Also, we introduced an additional intervention in the memory process through rapid eye movement sleep deprivation (REMSD). We observed a REMSD-induced trend in reversing the memory impairment caused by rotenone administration. Associated to this phenotype, we observed a significant increase in Mmp-7/Reck and Mmp-9/Reck mRNA expression ratio in the substantia nigra and Mmp-9/Reck ratio in the hypothalamus. Moreover, the positive correlation of Mmp/Reck expression ratios between the substantia nigra and the striatum, observed upon rotenone infusion, was reversed by REMSD. Taken together, our results suggest a potential orchestrated association between an increase in Mmp-7 and Mmp-9/Reck expression ratios in the substantia nigra and a possible positive effect on cognitive performance in subjects affected by PD.

Abstract. One of the major challenges in studies of activity and movement ecology is discovering how and why animals behave differently in certain environments.
