Small amphipathic polypeptides that can reduce the viability of bacterial cells are known as antimicrobial polypeptides (AMPs). Permeabilization of lipid bilayers by AMPs has been previously investigated in model lipid systems that mimic aspects of bacterial membrane composition. Model studies, however, do not address the possibility that polypeptide antimicrobial activity might also involve...
Weakly electric fish produce a high-frequency oscillating electric field that allows them to navigate and communicate in the dark. Their clock-like signal is the least variable of any known biological oscillator, but the mechanisms underlying this extreme precision are not clear. We recorded electric discharges in Apteronotus albifrons (blackghost knifefish) at 50MHz sampling frequency to...
Insertion and deletion mutations are common events in protein evolution but occur much less frequently than point mutations. Due to this, the effects of insertions and deletions on the biophysical properties of proteins are much less studied and understood.
A continuous three-letter protein model was used to study the effects of these mutations on the folding and stability of proteins....
The biomedical imaging community has recently seen a tremendous development of novel ultrasound-based tissue characterization techniques. These methods often involve the application of an external stimulus and the measurement of the tissue response, from which tissue properties can be inferred. To further the development of these tissue characterization techniques, one needs to characterize...
The aim of this study was to investigate the effect of femtosecond Laser Induced Periodic Surface Structures (LIPSS) with different periodicities in the range of 300 nm to 800 nm on osteoblast-like cells (i.e., Saos-2, osteosarcoma) growth on titanium. Femtosecond pulses from Yb:KGW laser source were used to synthesize LIPSS on titanium at fundamental wavelength of 1030 nm with a pulse...

Giant Axonal Neuropathy (GAN) follows an autosomal recessive genetic inheritance and impedes the peripheral and central nervous system due to axonal swellings that are packed with neuro-filaments. The patients display a number of phenotypes, including hypotonia, muscle weakness, decreased...
