Tracing the distribution of european lactase persistence genotypes along the Americas
(2021) [Artigo de periódico]In adulthood, the ability to digest lactose, the main sugar present in milk of mammals, is a phenotype (lactase persistence) observed in historically herder populations, mainly Northern Europeans, Eastern Africans, and ... -
Tracking marine tetrapod carcasses using a low-cost mixed methodology with GPS trackers, passive drifters and citizen science
(2023) [Artigo de periódico]Drift experiments are essential to understand stranding patterns and estimate the mortality of beached animals. Most studies do not use telemetry technology due to the high costs of this methodology. The objective of this ... -
Traditional botanical knowledge of artisanal fishers in southern Brazil
(2013) [Artigo de periódico]Background: This study characterized the botanical knowledge of artisanal fishers of the Lami community, Porto Alegre, southern Brazil based on answers to the following question: Is the local botanical knowledge of the ... -
Transcatheter aortic valve implantation for pure native aortic regurgitation : the last frontier
(2022) [Artigo de periódico]Transcatheter aortic valve implantation (TAVI) to treat patients with severe symptomatic aortic stenosis is a well-established procedure. Even though cases series have reported TAVI use in high-risk patients with pure ... -
Transcranial direct current stimulation combined with exercise modulates the inflammatory profile and hyperalgesic response in rats subjected to a neuropathic pain model : long-term effects
(2020) [Artigo de periódico]Background: Behavioral alterations, like mechanical and thermal hyperalgesia, and modulation of biomarkers in the peripheral and central nervous systems (CNS) are markers of chronic pain. Transcranial direct current ... -
Transcranial direct current stimulation in patients with anxiety : current perspectives
(2020) [Artigo de periódico]Anxiety is one of the most prevalent and debilitating psychiatric conditions worldwide. Pharmaco- and psycho-therapies have been employed in the treatment of human anxiety to date. Yet, either alone or in combination, ... -
Transcranial direct current stimulation to improve the dysfunction of descending pain modulatory system related to opioids in chronic non-cancer pain : an integrative review of neurobiology and meta-analysis
(2019) [Artigo de periódico]Background: Opioid long-term therapy can produce tolerance, opioid-induced hyperalgesia (OIH), and it induces dysfunction in pain descending pain inhibitory system (DPIS). Objectives: This integrative review with meta-analysis ... -
Transcriptional analysis allows genome reannotation and reveals that Cryptococcus gattii VGII undergoes nutrient restriction during infection
(2017) [Artigo de periódico]Cryptococcus gattii is a human and animal pathogen that infects healthy hosts and caused the Pacific Northwest outbreak of cryptococcosis. The inhalation of infectious propagules can lead to internalization of cryptococcal ... -
Transcriptional plasticity bufers genetic variation in zinc homeostasis
(2019) [Artigo de periódico]In roots of Arabidopsis thaliana, Zn can be either loaded into the xylem for translocation to the shoot or stored in vacuoles. Vacuolar storage is achieved through the action of the Zn/Cd transporter HMA3 (Heavy Metal ... -
Transcriptional profiling of Saccharomyces cerevisiae exposed to propolis
(2012) [Artigo de periódico]Background: Propolis is a natural product of plant resins collected by honeybees (Apis mellifera) from various plant sources. Our previous studies indicated that propolis sensitivity is dependent on the mitochondrial ... -
