Automated three-dimensional single cell phenotyping of spindle dynamics, cell shape, and volume [PDF]

open access: yesarXiv, 2015
We present feature finding and tracking algorithms in 3D in living cells, and demonstrate their utility to measure metrics important in cell biological processes. We developed a computational imaging hybrid approach that combines automated three-dimensional tracking of point-like features with surface determination from which cell (or nuclear) volume ...

Experimental Investigation and Characterization of Biodiesel From Aregmone ocheroleuca

open access: yesEnergy Science &Engineering, EarlyView.
The experimental investigation and characterization of biodiesel derived from Aregmone ochroleuca, a plant known for its oil‐rich seeds. The production of biodiesel from argemone oil, methanol, and potassium hydroxide catalysis through transesterification methods, and then characterized their properties, like the Effect of Reaction Temperature on ...

Exposure to diisononyl phthalate deteriorates the quality of porcine oocytes by inducing the apoptosis

open access: yesEcotoxicology and Environmental Safety, 2023
Diisononyl phthalate (DINP), a mixture of chemical compounds composed of diverse isononyl esters of phthalic acid, is commonly applied as a plasticizer to substitute for di (2-ethylhexyl) phthalate (DEHP).

Dynamic stability of spindles controlled by molecular motor kinetics [PDF]

open access: yesarXiv, 2006
We analyze the role of the force-dependent kinetics of motor proteins in the stability of antiparallel arrays of polar filaments, such as those in the mitotic spindle. We determine the possible stable structures and show that there exists an instability associated to the collective behavior of motors that leads to the collapse of the spindle.

Research progress on the depth of anesthesia monitoring based on the electroencephalogram

open access: yesIbrain, Volume 11, Issue 1, Page 32-43, Spring 2025.
Electroencephalogram (EEG) can noninvasive, continuous, and real‐time monitor the state of brain electrical activity, and the monitoring of EEG can reflect changes in the depth of anesthesia (DOA). The development of artificial intelligence can enable anesthesiologists to extract, analyze, and quantify DOA from complex EEG data.

Microtubule Dynamics and Oscillating State for Mitotic Spindle [PDF]

open access: yesarXiv, 2010
We present a physical mechanism that can cause the mitotic spindle to oscillate. The driving force for this mechanism emerges from the polymerization of astral microtubules interacting with the cell cortex. We show that Brownian ratchet model for growing microtubules reaching the cell cortex, mediate an effective mass to the spindle body and therefore ...

Roles of nanomagnetic beads on biosensing: From fabrication to application

open access: yesInterdisciplinary Medicine, EarlyView.
Leveraging their intrinsic superparamagnetic properties and rapid magnetic responsiveness, functionalized nanomagnetic beads have emerged as pivotal platforms in advanced biosensing system. Through surface engineering and structural design, these magnetic nanoparticles demonstrate multi‐capabilities, such as sample separation, signal enhancement, and ...
