The black fig fly is an exotic and invasive pest of figs in several producing areas of Mexico. The larvae of this species feed on the internal tissue of the syconium, causing rot and premature drop. In addition to , other species of fruit flies can be associated with figs in Mexico. Therefore the recognition of their immature stages is useful for plant health inspection procedures and timely management decisions. This study aimed to describe the egg, larva (L3) and puparium stages of , provide photographic material for their recognition and discuss the most important external morphological characteristics to differentiate them from and and discriminated amongst other species of Diptera of the Drosophilidae and Tephritidae families associated with figs.

Unlike differentiated somatic cells, which possess elongated mitochondria, undifferentiated cells, such as those of preimplantation embryos, possess round, immature mitochondria. Mitochondrial morphology changes dynamically during cell differentiation in a process called mitochondrial maturation. The significance of the alignment between cell differentiation and mitochondrial maturity in preimplantation development remains unclear.

The current study provides the first ultrastructural observations on the intraerythrocytic stages of so-called Haemogregarina damiettae and their cytopathological effects on the infected erythrocytes (IEs) in addition to the recording of new morphometric data. The intraerythrocytic stages are attributed to the immature forms or trophozoites (Ts), and mature gamonts (Gs). Ts are typically bowling-bottle shaped with nucleus (TN) occupying its globose part, while Gs are typically banana- shaped.

This study investigated the potential of extended irradiation combined with immature embryo culture techniques to accelerate generation advancements in safflower ( L.) breeding programs. We developed an efficient speed breeding method by applying light-emitting diodes (LEDs) that emit specific wavelengths, alongside the in vitro germination of immature embryos under controlled environmental conditions.

Immaturities exist at multiple levels of the developing human visual pathway, starting with immaturities in photon efficiency and spatial sampling in the retina and on through immaturities in early and later stages of cortical processing. Here we use Steady-State Visual Evoked Potentials (SSVEPs) and controlled visual stimuli to determine the degree to which sensitivity to horizontal retinal disparity is limited by the visibility of the monocular half-images, the ability to encode absolute disparity or the ability to encode relative disparity. Responses were recorded from male and female human participants at average ages of 5.

Understanding the interplay between biology and mechanics in tissue architecture is challenging, particularly in terms of 3D tissue organization. Addressing this challenge requires a biological model enabling observations at multiple levels from cell to tissue, as well as theoretical and computational approaches enabling the generation of a synthetic model that is relevant to the biological model and allowing for investigation of the mechanical stresses experienced by the tissue. Using a monolayer human colon epithelium organoid as a biological model, freely available tools (Fiji, Cellpose, Napari, Morphonet, or Tyssue library), and the commercially available Abaqus FEM solver, we combined vertex and FEM approaches to generate a comprehensive viscoelastic finite element model of the human colon organoid and demonstrated its flexibility.
