Preliminary study of metabolic radiotherapy with 188Re via small animal imaging [PDF]

open access: yesarXiv, 2005
188Re is a beta- (Emax = 2.12 MeV) and gamma (155 keV) emitter. Since its chemistry is similar to that of the largely employed tracer, 99mTc, molecules of hyaluronic acid (HA) have been labelled with 188Re to produce a target specific radiopharmaceutical. The radiolabeled compound, i.v.

Evidence that self-similar microrheology of highly entangled polymeric solutions scales robustly with, and is tunable by, polymer concentration [PDF]

open access: yesarXiv, 2018
We report observations of a remarkable scaling behavior with respect to concentration in the passive microbead rheology of two highly entangled polymeric solutions, polyethylene oxide (PEO) and hyaluronic acid (HA). This behavior was reported previously [Hill et al., PLOS ONE (2014)] for human lung mucus, a complex biological hydrogel, motivating the ...

INFLUENCE OF HYALURONIC ACID IN PERIODONTAL TISSUE REGENERATION

open access: yesRomanian Journal of Oral Rehabilitation, 2013
Hyaluronic acid is a high molecular weight polysaccharide (glycosaminoglycan), which plays a vital role in the functioning of extracellular matrices, including those of mineralized and non-mineralized periodontal tissues.

Efficacy of 0.2% hyaluronic acid in the healing of skin abrasions in rats

open access: yesHeliyon, 2021
Acute injuries, such as surgical and traumatic, heal normally in an organized and rapid manner. Studies point to the healing activity of hyaluronic acid in all phases of healing.

Acid zeta function and ajoint acid zeta function [PDF]

open access: yesarXiv, 2010
In this paper we set up the theory of acid zeta function and ajoint acid zeta function, based on the theory, we point out a reason to doubt the truth of the Riemann hypothesis and also as a consequence, we give out some new RH equivalences.

Is Amino-Acid Homochirality Due To Asymmetric Photolysis In Space? [PDF]

open access: yesarXiv, 1999
Amino acids occurring in proteins are, with rare exceptions, exclusively of the L-configuration. Among the many scenarios put forward to explain the origin of this chiral homogeneity (i.e., homochirality), one involves the asymmetric photolysis of amino acids present in space, triggered by circularly polarized UV radiation.

Are Strong Bronsted Acids Necessarily Strong Lewis Acids? [PDF]

open access: yesarXiv, 2006
The Broensted and Lowry acid base theory is based on the capacity of proton donation or acceptance (in the presence or absence of a solvent) whereas the Lewis acid base theory is based on the propensity of electron pair acceptance or donation. We explore through DFT calculation the obvious question whether these two theories are in conformity with each
