The significant rise in implementation and applications of plasmonic nanosystems in biophysics, biochemistry, and medicine has culminated in the emergence of refined plasmonic enabling reagents, or “nanoagents”. Thes...

The Latin American Federation of Biophysical Societies (LAFeBS) was founded in 2007 to encourage the development and dissemination of knowledge in biophysics. The Federation comprises biophysical societies and groups of ...

Probing light–matter interaction at the nanometer scale is one of the most fascinating topics of modern optics. Its importance is underlined by the large span of fields in which such accurate knowledge of light–matte...

Neurons tend to fire a spike when they are near a bifurcation from the resting state to spiking activity. It is a delicate balance between noise, dynamic currents and initial condition that determines the phase diagram o...

We present DevStaR, an automated computer vision and machine learning system that provides rapid, accurate, and quantitative measurements of C. elegans embryonic viability in high-throughput (HTP) applications. A l...

O autor se reporta a apregoadas crises tanto na fisiologia, como é classicamente entendida, como na que se convencionou chamar fisiologia animal comparativa. Na primeira, a crise residiria em estar cedendo lugar às dis...

Technological breakthroughs in the super-resolution optical imaging techniques have enriched our current understanding of a range of biological systems and biomolecular processes at the nanoscopic spatial resolution. Pro...

The confinement and manipulation of Janus particles have recently garnered significant interest due to their potential applications in fields such as nanotechnology and biophysics, where, under specific circumstances, th...

Opto-thermoelectric tweezers present a new paradigm for optical trapping and manipulation of particles using low-power and simple optics. New real-life applications of opto-thermoelectric tweezers in areas such as biophy...

The fundamental understanding of molecular quantum electrodynamics via the strong light–matter interactions between a nanophotonic cavity and quantum emitters opens various applications in quantum biology, biophysics, ...

Beyond diffraction limit, multitrapping of nanoparticles is important in numerous scientific fields, including biophysics, materials science and quantum optics. Here, we demonstrate the 3-dimensional (3D) shell-like stru...

Narrow band (311 nm) UVB phototherapy is established treatment for psoriasis. DNA is a target for UVB via formation of cyclobutane pyrimidine dimers, which trigger loss of dendritic cells and macrophages, and inhibit CD4...

Conocida como ácido ascórbico, la Vitamina C es una vitamina que interviene en múltiples procesos, tales como: formación de hormonas, neurotransmisores, carnitina, conversión del colesterol en ácidos biliares, incr...

Xenopus laevis oocytes were injected with [14C] phe-tRNA and the fate of the aminoacyl moiety was studied. The radioactive phenylalanine is gradually hydrolized off the tRNA once inside the cell. The rate of deacylation ...

The aggregation of proteins into amyloid fibers is linked to more than forty still incurable cellular and neurodegenerative diseases such as Parkinson’s disease (PD), multiple system atrophy, Alzheimer’s disease and ...

In this study, we explore Deisboeck and Z. Wang's conjecture from 2007, which establishes a quantitative relationship between the spatial expansion of tumours and the volume constraints as well as functional variations o...

The ability of the cellular prion protein (PrPC) to bind copper in vivo points to a physiological role for PrPC in copper transport. Six copper binding sites have been identified in the nonstructured N-terminal region of...

Rational protein design has successfully enhanced the mechanical stability of biomaterials by optimizing the internal topology of force-bearing domains. However, current design strategies predominantly focus on isolated ...

Neurotransmitters play fundamental regulatory roles within the central nervous system (CNS), where they modulate neuronal signaling and maintain neural network homeostasis. Beyond their classical functions in the CNS, th...
