The secret world of shrimps: polarisation vision at its best [PDF]

open access: yes, 2008
Animal vision spans a great range of complexity, with systems evolving to detect variations in optical intensity, distribution, colour, and polarisation.

Morphologic observations of human T and B lymphocytes by scanning electron microscopy [PDF]

open access: yes, 1974
T cell concerned with cell mediated immunity and B cell concerned with humoral antibody are classified by scanning electron microscopy of the surface structure of lymphocytes using E binding lymphocytes and EAC (sensitized sheep erythrocytes treated with

Pre-implantation mouse embryos cultured In vitro under different oxygen concentrations show altered ultrastructures [PDF]

open access: yes, 2020
Assisted Reproductive Technologies routinely utilize different culture media and oxygen (O2) concentrations to culture human embryos. Overall, embryos cultured under physiological O2 tension (5%) have improved development compared to embryos cultured ...

The cell adhesion molecule Fasciclin2 regulates brush border length and organization in Drosophila renal tubules [PDF]

open access: yes, 2016
Multicellular organisms rely on cell adhesion molecules to coordinate cell–cell interactions, and to provide navigational cues during tissue formation.

A cell line derived from BBN (N-butyl-N-[4-hydroxybutyl]-nitrosamine)-induced rat bladder cancer: establishment and scanning electron microscopic cell surface characteristics [PDF]

open access: yes, 1978
This research was performed to establish a cell line from experimental bladder tumor and to discuss the biological characteristics of the cell line so established. Tissue cultures of epithelial cells were derived from a rat bladder cancer induced by BBN.

Random Photon Absorption Model Elucidates How Early Gain Control in Fly Photoreceptors Arises from Quantal Sampling [PDF]

open access: yes, 2016
Many diurnal photoreceptors encode vast real-world light changes effectively, but how this performance originates from photon sampling is unclear. A 4-module biophysically-realistic fly photoreceptor model, in which information capture is limited by the ...

On Top of the Alveolar Epithelium: Surfactant and the Glycocalyx [PDF]

open access: yes, 2020
Gas exchange in the lung takes place via the air-blood barrier in the septal walls of alveoli. The tissue elements that oxygen molecules have to cross are the alveolar epithelium, the interstitium and the capillary endothelium.

Reversibility of cell surface label rearrangement [PDF]

open access: yes, 1976
Cell surface labeling can cause rearrangements of randomly distributed membrane components. Removal of the label bound to the cell surface allows the membrane components to return to their original random distribution, demonstrating that label is ...

New immunolatex spheres: visual markers of antigens on lymphocytes for scanning electron microscopy [PDF]

open access: yes, 1975
New immunochemical reagents consisting of antibodies bound to small latex spheres were used as visual markers for the detection and localization of cell surface antigens by scanning electron microscopy.

Distribution of glycan motifs at the surface of midgut cells in the cotton leafworm (Spodoptera littoralis) demonstrated by lectin binding [PDF]

open access: yes, 2017
Glycans are involved in many biological phenomena, including signal transduction, cell adhesion, immune response or differentiation. Although a few papers have reported on the role of glycans in the development and proper functioning of the insect midgut,
