Papel da vitamina B12 na patogenia da mielose funicular

open access: yesArquivos de Neuro-Psiquiatria, 1965
Foi estudada a absorção da vitamina B12 radioativa em 29 casos de mielose funicular. O diagnóstico baseou-se na clássica sintomatologia neu- rológica e na presença de acloridria gástrica e eventuais alterações hemato-lógicas.

The origin and evolution of Dolichoderinae, a dominant ant clade (Hymenoptera: Formicidae)

open access: yesSystematic Entomology, Volume 51, Issue 4, October–December 2026.
The phylogeny of Dolichoderinae is inferred from phylogenomic data for the first time, based on 131 terminals representing all extant genera except Ecphorella, with divergence dating and time‐stratified historical biogeography. Novel phylogenetic relationships facilitate a new informal classification of genus groups, the erection of Paranillidris gen ...

New records of extinct Icacinaceae from Paleocene rainforests of northwestern South America

open access: yesAmerican Journal of Botany, Volume 113, Issue 7, July 2026.
Abstract Premise This study describes three new records of Icacinaceae—Punctiuga bachue gen. et sp. nov., Palaeophytocrene paramoae sp. nov., and Goweria bacatana sp. nov. from the Paleocene (Selandian–Thanetian) Bogotá Formation in Colombia—improving understanding of the distribution and evolution of this family in the Neotropics.

Numerical Investigation of the Influence of Interparticle Cohesion During the Shear Behavior of Granular Soil

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 9, Page 4020-4035, 25 June 2026.
ABSTRACT Interparticle cohesive forces play a crucial role in governing the shear behavior of many soils; however, quantifying this effect remains challenging due to limited microscopic insights available from laboratory experiments. In this context, the current study aims to investigate the influence of microscale cohesion on the shear response using ...

Identifying Thermodynamic Regimes of CO2 Gas Exchange During the Melt Transition on First‐Year Sea Ice Using a Multi‐Sensor Synthetic Aperture Radar Approach

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Few multi‐year observations of CO2 gas exchange exist over melting first year sea ice (FYI). We report 4 years of CO2 flux data during the melt season in Dease Strait, Nunavut, Canada. Utilizing a dried, closed‐path eddy covariance system on an island within the strait, we identify two statistically distinct CO2 flux melt regimes: a pre‐pond ...

Early acclimatization to high altitude: Acid–base and fluid balance dynamics during the first 2 days at 3100 m

open access: yesExperimental Physiology, Volume 111, Issue 3, Page 1387-1396, 1 March 2026.
Abstract Immediate responses to hypoxia at high altitude are hyperventilation and successive respiratory alkalosis. Alkalosis, in turn, can affect cerebrospinal fluid pH and ventilatory control. The kidneys compensate metabolically for respiratory alkalosis.

To the problem of essential early diagnostics of funicular myelosis

open access: yesМедицинский вестник Юга России, 2010
Purpose: to assess indices of peripheral blood and marrow of patients with funicular myelosis in comparison with anamnesis data in order to establish the reason of mielinopathy development to prescribe early pathogenic therapy.
