Articulation Morphology of Plants and Plant Evo-Devo: An Open Morphology—Empirical, Dynamic, All-Inclusive, and Unifying [PDF]

open access: yesPlants
In Articulation Morphology, inspired by the theory of anaphytes that was first proposed in 1843, ramification is the key principle in plant morphology in the open growth of plants.

Practice of the Incomplete $p$-Ramification Over a Number Field -- History of Abelian $p$-Ramification [PDF]

open access: yesCommunications in Advanced Mathematical Sciences, 2019
The theory of $p$-ramification, regarding the Galois group of the maximal pro-$p$-extension of a number field $K$, unramified outside $p$ and $\infty$, is well known including numerical experiments with PARI/GP programs.

Microapical surgery of a periapical cyst caused by apical ramification: a case report and review of the literature [PDF]

open access: yesJournal of Medical Case Reports
Background The destruction of tooth apical bone mainly comes from odontogenic apical cysts caused by pulp necrosis, chronic inflammation, or trauma. Some affected teeth can be cured by modern root canal treatment or non-surgical retreatment, but some ...

Functional and Metabolic Characterization of Microglia Culture in a Defined Medium

open access: yesFrontiers in Cellular Neuroscience, 2020
Microglia are the endogenous immune cells of the brain and act as sensor of infection and pathologic injury to the brain, leading to a rapid plastic process of activation that culminates in the endocytosis and phagocytosis of damaged tissue.

Course and branch of the celiac artery in the red falcon (Buteo rufinus)

open access: yesVeterinární Medicína, 2010
The present study was aimed at determining the origin, course and distribution of the celiac artery in eight adult red falcons, using a latex injection and dissection method.

Ramification has little impact on shoot hydraulic efficiency in the sexually dimorphic genus Leucadendron (Proteaceae) [PDF]

open access: yesPeerJ, 2019
Despite the diversity of branching architectures in plants, the impact of this morphological variation on hydraulic efficiency has been poorly studied.

Mouse Astrocytes Promote Microglial Ramification by Releasing TGF-β and Forming Glial Fibers

open access: yesFrontiers in Cellular Neuroscience, 2020
The morphology of microglial cells is often closely related to their functions. The mechanisms that regulate microglial ramification are not well understood.

On the necessity of new ramification breaks [PDF]

open access: yes, 2009
Ramification invariants are necessary, but not in general sufficient, to determine the Galois module structure of ideals in local number field extensions. This insufficiency is associated with elementary abelian extensions, where one can define a refined

Study on the portal ramification pattern of the right anterior sector of the liver and a unique medial branch (PV8c) of the right anterior portal vein

open access: yesAnnals of Gastroenterological Surgery, 2022
Aim The concept of Couinaud segmentation is widely used in clinical practice. However, there were no definite anatomical landmarks between segments V and VIII. Therefore, segmentation of the right anterior sector is still controversial.

Caracterização e dinâmica de duas fases sucessionais em floresta secundária da mata atlântica Characterization and dynamics of two successional stages of secondary atlantic forest

open access: yesRevista Árvore, 2009
Em Santa Catarina, foi observado aumento da cobertura florestal nas últimas décadas, o que vem construindo uma paisagem florestal retalhada por um grande mosaico de fragmentos de vários estádios sucessionais. Neste trabalho, buscou-se avaliar o dinamismo
