Comparison of Anti-Viral Activity of Frog Skin Anti-Microbial Peptides Temporin-Sha and [K3]SHa to LL-37 and Temporin-Tb against Herpes Simplex Virus Type 1

Viruses, 2019
Temporins are anti-microbial peptides synthesized in the skin of frogs of the Ranidae family. The few studies to date that have examined their anti-viral properties have shown that they have potential as anti-viral therapies.

Evaluating the efficacy of eggshell-derived hydroxyapatite (EHA) and synthetic hydroxyapatite (SHA) in bone regeneration of maxillofacial defects-a randomized double-blind pilot comparative clinical-radiological study [PDF]

Journal of Oral Biology and Craniofacial Research
Background: Defects of the maxillofacial skeleton lead to functional, aesthetic, social, and behavioral problems, that make the person isolate from the mainstream of society. So, bone regeneration is needed for the overall health. Since long time various

Faster bowel recovery with superior haemorrhoidal artery preservation in patients undergoing sigmoidectomy for diverticular disease: A retrospective cohort study from the diverticular disease registry trial [PDF]

Journal of Minimal Access Surgery
Introduction: The pathogenesis of diverticular disease varies significantly and so does its clinical presentation. The procedure for left-sided diverticular disease is standardised, but there is still no consensus on the level of arterial ligation.

Realization of low-loss tunable metasurfaces based on a shunting interdigitated capacitance structure

Results in Physics, 2023
Based on interdigitated capacitance structure (ICS), a method for realizing low-loss tunable metasurfaces (TMS) is proposed in the paper. The variation in the metal patch structure and the PIN diode position indicates that introducing additional ...

SHA-1 and the Strict Avalanche Criterion [PDF]

2016 Information Security for South Africa (ISSA), 2016
The Strict Avalanche Criterion (SAC) is a measure of both confusion and diffusion, which are key properties of a cryptographic hash function. This work provides a working definition of the SAC, describes an experimental methodology that can be used to statistically evaluate whether a cryptographic hash meets the SAC, and uses this to investigate the ...
