Molecularly imprinted polymers (MIPs) and cell-imprinter (CIPs) have emerged as synthetic recognition elements in biomimetic sensors. In this paper, we conducted a parametric study to optimize bulk polymerization methodology for uniform functionalization of stainless steel microwires (MWs) with CIPs comprising single fourplex combinations functional monomers (FMs). MWs are widely used biosensors, their single-FM MIPs has been demonstrated. Complex multiple FMs shown enhanced selectivity...

Abstract Behavioral responses of zebrafish larvae to environmental cues are important functional readouts that should be evoked on-demand and studied phenotypically in behavioral, genetical developmental investigations. Very recently, it was shown execute a voluntary oriented movement toward the positive electrode an electric field along microchannel. Phenotypic characterization this response not feasible due larva’s rapid channel. To overcome challenge, microfluidic device introduced...

In this paper, we report a novel microfluidic method to conduct Caenorhabditis elegans electrotaxis movement assay and neuronal imaging on up 16 worms in parallel. C. is model organism for neurodegenerative disease disorders such as Parkinson's (PD), screening chemicals that alleviate protein aggregation, death, impairment PD. Electrotaxis of channels has led the development neurobehavioral platforms, but enhancing throughput electrotactic behavioral remained challenge. Our device consisted...

Microfluidic devices are being used for phenotypic screening of zebrafish larvae in fundamental and pre-clinical research. A challenge the broad use these microfluidic is their low throughput, especially behavioral assays. Previously, we introduced tail locomotion a semi-mobile larva evoked on-demand with electric signal device. Here, report lessons learned increasing number specimens from one to four this device.Multiple parameters including loading testing time per fish orientation...

The present work investigates the performance of Savonius wind turbine using two or three rotors. new design was found to have higher power coefficient compared with single rotor design. peak average rotors computed be 50% than that torque also at high tip speed ratio. This improved is attributed favorable aerodynamic interaction between which accelerates flow around and generates turning in direction rotation for each rotor. optimized arrangement showed upstream one downstream should a...

In this paper, the novel effect of electric field (EF) on adult C. elegans egg-laying in a microchannel is discovered and correlated with neural muscular activities. The quantitative effects worm aging EF strength, direction, exposure duration are studied phenotypically using egg-count, body length, head movement, transient neuronal activity readouts. Electric rate increases significantly when worms face anode response EF-dependent, i.e. stronger (6 V cm-1) longer (40 s) result shorter egg...

Rheological properties, peroxide value, and FTIR spectra of olive, chia, garden cress oils exposed to high temperatures (150, 175, 200 ºC) for different times (30, 60, 120 minutes) were assayed. The shear stress versus rate data (at 25 was fitted Newtonian, Bingham, power law rheological mathematical models. Fresh tested showed Newtonian flow behavior with correlation coefficients higher than 0.99 slight non-Newtonian after heat treatment at times. values the significantly increased...

Abstract Background Achalasia is characterized by the absence of peristaltic movement in lower esophageal sphincter, resulting impaired relaxation during food ingestion. The incidence achalasia similar between men and women, affecting approximately 1 100,000 individuals annually, with a prevalence 10 people. It most commonly diagnosed ages 30 60 years. High-resolution manometry considered gold standard for diagnosis, revealing body aperistalsis hypertensive sphincter. While laparoscopic...

Caenorhabditis elegans ( C. ) is an optically transparent nematode that shares many gene orthologs and homologs with humans. are widely used in large populations for genetic studies relevant to human biology disease.
