The invention provides means for controlling the flow of fluids such as parenteral fluids. It comprises a body and flexing means. The body defines a passageway with opposed flexible walls which can be held in contact throughout their cross-section except for a limited region of which the cross...
(e,f) Details of (c) and (d) highlighting the multi-layered organisation of the melanin (asterisk) in the outermost cuticular layers of the dorsal side. (g) Cross section of the wing distal margin where the dorsal (D) and ventral (V) laminae have similar thickness. (h) Cross section...
The organisation of cells of the planctomycete species Pirellula marina, Isosphaera pallida, Gemmata obscuriglobus, Planctomyces maris and "Candidatus Brocadia anammoxidans" was investigated based on ultrastructure derived from thin-sections of cryosubstituted cells, freeze-fracture replicas, and in th...

This is because of the nature of collagen; a protein that is usually found in a highly coiled structural arrangement throughout different levels of tissue hierarchy or structural organisation. Collagen structures stretch under load, storing potential elastic energy and recoil when that load is removed...

Next, we assessed whether the spatial variability in structure–function decoupling aligns with fundamental properties of cortical organisation. Using diffusion map embedding for non-linear dimensionality reduction46, we derived structural and functional gradients of cortical organisation for each control part...
Many cells unite to form a tissue. Many tissues unite to form an organ and many organs unite to form organ system. The body is made up of thousands of cells in Hydra in which each cell works independently while in complex body system (eg. human) crores o
(1) appreciate the complex corticomedullary organisation of the entire human organ in 3D; and (2) provide the first volumetric visualisation of the HB morphology, with previous studies endeavouring to describe HBs having extracted morphological information only in a 2D fashion using essentially ...
In meiosis, a supramolecular protein structure, the synaptonemal complex (SC), assembles between homologous chromosomes to facilitate their recombination. Mammalian SC formation is thought to involve hierarchical zipper-like assembly of an SYCP1 protein
