The replication band in the macronucleus of ciliated protozoa has fascinated microscopists since the 19 Century. It migrates through the nucleus, corresponding to a region of DNA replication and nascent chromatin assembly. A new study shows that calcium and actin filaments may participate in the formation and migration of the replication band.

Contralateral Neurovascular Coupling in Patients with Ischemic Stroke After Endovascular Thrombectomy.

Background: Neurovascular coupling (NVC) refers to the process of aligning cerebral blood flow with neuronal metabolic demand. This study explores the potential of contralateral NVC-linking neural electrical activity on the stroke side with cerebral blood flow velocity (CBFV) on the contralesional side-as a marker of physiological function of the brain. Our aim was to examine the association between contralateral NVC and neurological outcomes in patients with ischemic stroke following endovascular thrombectomy.

Recently, Organ-on-a-Chip (OoC) platforms have arisen as an increasingly relevant experimental tool for successfully replicating human physiology and disease. However, there is a lack of a standard technology to monitor the OoC parameters, especially in a non-invasive and label-free way. Photoacoustic (PA) systems can be considered an alternative and accurate assessment method for OoC platforms.

Background: To our knowledge capture-recapture techniques have not been used to estimate dementia prevalence using routinely collected data in England, nor have they been used to estimate changes in undiagnosed dementia over time. In this study we aimed to use routinely collected electronic health records to estimate the number of undiagnosed dementia cases there are in England and how this has changed over time. We also aimed to assess whether proportion of undiagnosed cases differed by age group, ethnicity, socioeconomic deprivation and sex.

Graphene is a class of two-dimensional (2D) nanomaterials composed of single or multiple layers of carbon atoms. To date, there are limited clinical data and no epidemiological research available to assess graphene toxicity in humans. Despite the growing amount of animal toxicity data, there are currently no occupational exposure limits (OELs) for any type of graphene nanomaterial published by international authoritative organizations to ensure their safe handling within workplaces.

A quantum-electrodynamics approach is presented to describe the dynamics of electrons that exchange energy with both photon and phonon baths. Our ansatz is a dissipative quantum Liouville equation, cast in the Redfield form, with two driving terms associated with radiative and vibrational relaxation mechanisms, respectively. Remarkably, within the radiative contribution, there is a term that exactly replicates the expression derived from a semiclassical treatment where the power dissipated by the electronic density is treated as the emission from a classical dipole [Bustamante et al.
