Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Simulation Study on the Reaction-Diffusion Coupling in Simple Pore Structures

open access: yes, 2017
Most porous media (just like catalyst pellets) have complicated pore structures, and understanding the coupling of the diffusion and reaction processes in these pores is very important for improving their performance.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Reaction time on fencing and karate high level athletes [PDF]

open access: yes, 2008
The great speed of the actions in combat sports makes very difficult to react quickJy without mistakes. If the fighter had longer time to react, their reaction would be more accurate.

Limb Weight Varying Effect on EMG Record of Simple and Discriminative Reaction Time in Elderly Men

open access: yesSālmand, 2014
Objectives: The effect of variation in contraction force is one of the most important factors in the organization and execution of reaction time (RT) tasks that most of elderly people involved it when they became obese.

Study on variation of simple reaction time during menstrual cycle among undergraduate medical students

open access: yesNational Journal of Physiology, Pharmacy and Pharmacology, 2020
Background: Females have a monthly cyclical change in the levels of estrogen and progesterone during the pre-menstrual and post-menstrual phase. These hormones affect the sensory-motor association.

Inhibition of cyclin‐dependent kinases 12/13 using CT7439 as a treatment for colorectal cancer with CDK12 upregulation

open access: yesMolecular Oncology, EarlyView.
The proposed mechanism of action for the CDK12/13 inhibitor and cyclin K degrader, CT7439. CDK12/13 inhibition interrupts transcription elongation, leading to increased DNA damage that results in cell death. This agent is a potentially novel treatment option for patients with colorectal cancer. Created in BioRender. Cyclin‐dependent kinase (CDK) 12 and

Effects of NaOH solution concentration and reaction time on metakaolin geopolymerization [PDF]

open access: yes, 2013
The products of metakaolin(MK)activated by NaOH solutions with different concentration and reaction time were analyzed by means of isothermal conductive calorimetry (ICC),X-ray diffraction(XRD)and Fourier transform infrared(FT-IR).

In vitro and in silico modelling of ROS1‐positive non‐small cell lung cancer reveals fusion‐dependent tyrosine kinase inhibitor responses

open access: yesMolecular Oncology, EarlyView.
Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.
