The tectonic evolution of the Neoproterozoic Brasília Belt, central Brazil: a geochronological and isotopic approach

Brazilian Journal of Geology
: The Brasília Belt is one of the most complete Neoproterozoic orogens in western Gondwana. Rapid progress on the understanding of the tectonic evolution of the belt was achieved due to new U-Pb data, combined with Sm-Nd and Lu-Hf analyses. The evolution

Increases in cardiac vagal modulation following muscle mechanoreflex activation via passive calf stretch: Impact of interindividual differences [PDF]

Experimental Physiology, Volume 111, Issue 1, Page 167-178, 1 January 2026.
Abstract Muscle mechanoreflex is crucial to cardiac vagal modulation during exercise and can be activated during passive calf stretch. Herein, we aimed to determine whether cardiac vagal modulation following a single session of passive stretch is linked to interindividual cardiac vagal responses at the onset of passive calf muscle stretching in healthy

Postinactivity Exercise Training Improves Sarcopenia Traits in 40–60‐Year‐Old Women Regardless of Fortified Milk Supplementation [PDF]

Journal of Cachexia, Sarcopenia and Muscle, Volume 16, Issue 6, December 2025.
ABSTRACT Background The term sarcopenia was introduced to describe the age‐related decline in muscle mass, but current definitions also include measures of muscle strength and function. Menopause increases sarcopenia risk and may exacerbate the adverse effects of physical inactivity.

Superposition of structures in the interference zone between the southern Brasília belt and the central Ribeira belt in the region SW of Itajubá (MG), SE Brazil

Brazilian Journal of Geology
: The study area is localized in the Socorro nappe, part of the southern Brasília belt, with a minor part in the Embu terrane, part of the central Ribeira belt. Three phases of deformation were detected, Dn-1, Dn and Dn+1.

Metamorphic modeling and petrochronology of metapelitic rocks from the Luminárias Nappe, southern Brasília belt (SE Brazil)

Brazilian Journal of Geology, 2019
The Luminárias Nappe was formed in the agglutination of West Gondwana. A high-pressure metamorphic gradient oblique to the geological contacts is recorded in metapelitic rocks from this Nappe.

Field resistance of orange fruit to citrus black spot and citrus canker in D‐limonene synthase downregulated trees [PDF]

Pest Management Science, Volume 82, Issue 4, Page 2949-2959, April 2026.
Genetically modified (GM) sweet‐oranges with downregulated CitMTSE1 gene showed reduced citrus black spot severity and citrus canker incidence, confirming terpene modulation as a promising strategy for sustainable field citrus disease resistance. Abstract BACKGROUND Citrus black spot (CBS), caused by Phyllosticta citricarpa, and citrus canker (CC ...

The thrust contact between the Canastra and Vazante groups in the Southern Brasília Belt: structural evolution, white mica crystallinity and implications for the Brasiliano orogeny

Brazilian Journal of Geology
: Two regional thrust-sheets of Neoproterozoic metasedimentary rocks occur in the Southern Brasília Belt, northwest Minas Gerais. The lower one comprises the Vazante Group, that is formed in the studied area, from base to top, by the Serra do Garrote ...

Final stages of the Brasiliano Orogenesis in SE Brazil: U-Pb and 40Ar/39Ar evidence for overprinting of the Brasília Belt by the Ribeira Belt Tectonics

, 2004
Around the southern margins of the São Francisco Craton, there is a zone of tectonic interference between the Brasília belt to the west and the younger Ribeira belt to the east.
