Morphological changes in soybean cultivars subjected to apical dominance removal at phenological stages [PDF]
: This study evaluated the effect of removing apical dominance at phenological stages on the agronomic traits of soybean cultivars. The experiment was conducted in the 2020/2021 growing season inthe teaching-experimental area of the Federal Institute of ...

Analysis of the apical constriction using micro-computed tomography and anatomical sections
Objectives: The aim of this study is to assess the morphology, the prevalence and the topography of the apical constriction (AC) through a tridimensional analysis and compare the results with the available data reported in the literature.

In all metazoan species, sperm is produced from germline stem cells. These self-renew and produce daughter cells that amplify and differentiate dependent on interactions with somatic support cells.

Magnetic properties of delta- and kagome-like chains with competing interactions [PDF]
We study the delta-chain with spin-1 on basal sites and spin- 12 on apical sites. The Heisenberg interaction between neighbor basal spins is antiferromagnetic (AF) and the interaction between basal and apical spins is ferromagnetic (F).

Selective coupling of coherent optical phonons in YBa$_2$Cu$_3$O$_{7-\delta}$ with electronic transitions [PDF]
We investigate coherent lattice dynamics in optimally doped YBa$_2$Cu$_3$O$_{7-\delta}$ driven by ultrashort ($\sim$ 12 fs) near infrared (NIR) and near ultraviolet (NUV) pulses. Transient reflectivity experiments, performed at room temperature and under

Micro-CT evaluation of maxillary first molars: interorifice distances and internal anatomy of the mesiobuccal root [PDF]
: This study aimed to describe the morphometric relationship of root canal orifices on the pulp floor in the presence/absence of mesiobuccal second canal (MB2) in the maxillary first molars and other aspects of its internal anatomy.

Homologous gene regulatory networks control development of apical organs and brains in Bilateria
Apical organs are relatively simple larval nervous systems. The extent to which apical organs are evolutionarily related to the more complex nervous systems of other animals remains unclear.

Cell fate determination is a necessary and tightly regulated process for producing different cell types and structures during development. Cranial neural crest cells (CNCCs) are unique to vertebrate embryos and emerge from the neural plate borders into ...
