Effects of carvacrol and physical exercise on motor and memory impairments associated with Parkinson’s disease

open access: yesArquivos de Neuro-Psiquiatria
The present study was undertaken to investigate the effects of carvacrol and treadmill exercise on memory deficit, rotational behavior and oxidative stress biomarkers in a 6-OHDA-lesioned rat model of Parkinson’s disease.

Investigation of Gyroscopic Effect on the Stability of High Speed Micromilling via Bifurcation Analysis

open access: yesJournal of Manufacturing and Materials Processing, 2021
Catastrophic tool failure due to the low flexural stiffness of the micro-tool is a major concern for micromanufacturing industries. This issue can be addressed using high rotational speed, but the gyroscopic couple becomes prominent at high rotational ...

Homoclinic, Subharmonic and Superharmonic Bifurcations for a Pendulum with Periodically Varying Length

open access: yes, 2014
Dynamic behavior of a weightless rod with a point mass sliding along the rod axis according to periodic law is studied. This is the simplest model of child's swing.

Chaotic Behavior of Rotational Barkhausen Noises.

open access: yesJournal of the Magnetics Society of Japan, 2001
This paper describes the chaotic behavior of Barkhausen noise. We previously revealed that Barkhausen noises under a rotational magnetic field were different from those under an alternating magnetic field, and showed that the heat fatigue level of Inconel-600 steel plates could be detected by using the proposed Barkhausen noises.

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

open access: yesFEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

A 16-Channel Automated Rotometer System for Reliable Measurement of Turning Behavior in 6-Hydroxydopamine Lesioned and Transplanted Rats

open access: yesCell Transplantation, 1993
Unilateral 6-hydroxydopamine lesions of the nigrostriatal pathway in rats result in a massive dopamine (DA) denervation of the ipsilateral striatum. Such animals have proven extremely useful as a model for the study of Parkinson's disease, an idiopathic ...

Model building in AdS/CMT: DC conductivity and Hall angle

open access: yes, 2011
Using the bottom-up approach in a holographic setting, we attempt to study both the transport and thermodynamic properties of a generic system in 3+1 dimensional bulk spacetime.

Self-diffusion in two-dimensional hard ellipsoid suspensions [PDF]

open access: yes, 2010
We studied the self-diffusion of colloidal ellipsoids in a monolayer near a flat wall by video microscopy. The image processing algorithm can track the positions and orientations of ellipsoids with sub-pixel resolution.

ON THE ROTATIONAL BEHAVIOR OF NEREID

open access: yesThe Astronomical Journal, 2011
We have conducted a set of numerical simulations of the combined orbital and rotational motion of Neptune's moon Nereid to study its rotational behavior under the influence of gravitational torques from Neptune. Due to the high eccentricity of its orbit, and the fact that the gravitational torque from Neptune varies as r ?3, Nereid experiences a large ...
