Abstract The underlying mechanisms of ventricular remodeling after myocardial infarction (MI) remain largely unknown. In this study, we performed an integrative analysis spatial transcriptomics and single-nucleus RNA sequencing (snRNA-seq) in a murine MI model found that mechanical stress-response genes are expressed at the border zone play critical role left MI. An snRNA-seq transcriptome hear...

BACKGROUND According to prevailing understanding, skeletal mechano-responsiveness declines with age and this apparent failure of the mechano-sensory feedback system has been attributed to the gradual bone loss with aging (age-related osteoporosis). The objective of this study was to evaluate whether the capacity of senescent skeleton to respond to increased loading is indeed reduced as compared...

The recent discovery of nuclear and perinuclear perlecan in annulus fibrosus nucleus pulposus cells its known matrix stabilizing properties tissues introduces the possibility that may also have intracellular or regulatory roles through interactions with envelope cytoskeletal proteins nucleosomal-chromatin organization regulate transcriptional factors modulate gene expression. is a mechano-senso...

nanoparticles of manganese-dioxide synthesized by mechano-chemical reaction were used foras(iii) and as(v) sorption from water environment. the influence of a milling time of manganese-dioxide on sorption was examined with batch procedure. sorption as a function of contact time was investigated. kinetic of sorption, for both as(iii) and as(v), was fast. the equilibrium condition for milled sorb...

introduction: peripheral nerve injury leads to neuropathic pain syndromes and different sensation like allodynia and hyperalgesia. different animal models of neuropathic pain are used to study the neuropathic pain mechanisms. the present study was performed on two models, (sni). the purpose of this study was comparing the behavioral responses of yhese two models and the role of saphenous and su...

We investigate the effect of mechano-electrical feedback and atrial fibrillation induced electrical remodelling (AFER) of cellular ion channel properties on the dynamics of spiral waves in a discrete 2D model of human atrial tissue. The tissue electro-mechanics are modelled using the discrete element method (DEM). Millions of bonded DEM particles form a network of coupled atrial cells represent...

It is still relatively unclear how intervertebral disc (IVD) cells sense a mechanical stimulus and convert this signal into a biochemical response. Previous studies demonstrated that the cytoskeletal elements are mechano-responsive in many cell types and may contribute to mechano-signalling pathways. The objective of this study was to determine the response of cells from the outer annulus fibro...

Bees navigate in complex environments using visual, olfactory and mechano-sensorial cues. In the lowest region of the atmosphere, the wind environment can be highly unsteady and bees employ fine motor-skills to enhance flight control. Recent work reveals sophisticated multi-modal processing of visual and olfactory channels by the bee brain to enhance foraging efficiency, but it currently remain...
