Animal Models and Experimental Medicine, Volume 7, Issue 6, Page 868-880, December 2024.Animal models have played a key role in neuroscience research for years. Nevertheless, their usage brings up ethical and transability issues concerning humans. In the recent years, alternative approaches have been developed, containing a potential for replacement and reduction of animal experimenting, associated with more relatable results. This review

Does Variation of the Inter-Domain Linker Sequence Modulate the Metal Binding Behaviour of Helix pomatia Cd-Metallothionein? [PDF]
, 2016 Snail metallothioneins (MTs) constitute an ideal model to study structure/function relationships in these metal-binding polypeptides. Helix pomatia harbours three MT isoforms: the highly specific CdMT and CuMT, and an unspecific Cd/CuMT, which represent ...

A new kind of slant helix in Pseudo-Riemannian Manifolds [PDF]
arXiv, 2013 In this paper, we define a new kind of slant helix called f-eikonal V_{n}-slant helix in Pseudo- Riemannian manifolds and give the definition of harmonic curvature functions related to the f-eikonal V_{n}-slant helix in Pseudo- Riemannian manifolds. Moreover, we give some characterizations of f-eikonal V_{n}-slant helix by making use of the harmonic ...

Compressive response and helix formation of a semi flexible polymer confined in a nanochannel [PDF]
, 2017 Configurations of a single semiflexible polymer is studied when it is pushed into a nanochannel in the case where the polymer persistence length $l_p$ is much longer than the channel diameter $D$, i.e. $l_p/D \gg 1$. Using numerical simulations, we show that the polymer undergoes a sequence of recurring structural transitions upon longitudinal ...

Ecology and Evolution, Volume 14, Issue 12, December 2024.Reliable protocols have been developed for the transport, maintenance, and controlled reproduction of Pinna nobilis, a highly endangered species. P. nobilis individuals were evaluated through molecular analyses during their stay in the laboratory tanks.

Role of hydration and intramolecular interactions in the helix-coil transition and helix-helix assembly in a deca-alanine peptide [PDF]
arXiv, 2015 For a model deca-alanine peptide the cavity (ideal hydrophobic) contribution to hydration favors the helix state in the coil-to-helix transition and the paired helix bundle in the assembly of two helices. The energetic contributions of attractive protein-solvent interactions are separated into a short-range part arising from interactions with solvent ...

Evolution of the genetic code. Emergence of DNA [PDF]
arXiv, 2008 This hypothesis can provide an opportunity to trace logically the process of the emergence of the DNA double helix. AT-enrichment in this hypothesis is main factor of evolution of DNA double helix from RNA double helix.

SmartMat, Volume 5, Issue 6, December 2024.Chiral hierarchical suprastructures of gypsum were obtained through a layer‐by‐layer inclination growth model controlled by the self‐assembly of chiral Asp enantiomers on an amorphous calcium sulfate mineral surface, which endows the gypsum with outstanding mechanical properties, including high strength and toughness.

The Helix Relation Between Two Curves [PDF]
arXiv, 2013 In this study, we give the relation of being general helix and slant helix of two curves by using the equation between them. Also we find some results and express the characterizations of these curves.

Distribution of heavy metal concentrations in the different soft and hard tissues of tropical mud-flat snail telescopium telescopium (Family: Potamididae) collected from Sepang Besar River [PDF]
, 2012 The concentrations of Cd, Cu, Pb, Fe, Ni and Zn were determined in the different parts of the soft tissues (foot, cephalic tentacle, mantle, muscle, gill, digestive caecum and remaining soft tissues) and three parts of hard tissues or shells (anterior ...
