An expedited screening platform for the discovery of anti-ageing compounds in vitro and in vivo.

Background: Restraining or slowing ageing hallmarks at the cellular level have been proposed as a route to increased organismal lifespan and healthspan. Consequently, there is great interest in anti-ageing drug discovery. However, this currently requires laborious and lengthy longevity analysis.

Moya moya vasculopathy and MECP2 duplication syndrome.

Background: Moya moya type vasculopathy (MMV) is a rare disorder in which there is narrowing of bilateral intracranial carotid arteries (Scott and Smith in New Engl J Med 360(12):1226-1237, 2009). MECP2 duplication syndrome (MDS) is a rare genetic disorder that is caused by genetic duplications on Xq28 chromosome (Expanding the clinical picture of the MECP2 duplication syndrome. (Lim et al.

Cell density dependent restriction of N2O reductase in denitrifying Pseudomonas spp., a potential driver of N2O emissions in natural systems.

Denitrification is a major biological source and sink for the ozone-depleting greenhouse gas N2. Thus, the respiratory physiology of denitrifiers and the mechanisms determining their propensity for accumulation of N-oxides are of fundamental interest. Here, we report a pervasive positive correlation between cell density and N2O accumulation in Pseudomonas aeruginosa and P.

Impact of Giving Patients Your Personal Phone Number in Otolaryngology-Head & Neck Surgery.

Objective: Patient-provider communication is a major barrier to care, with some providers giving their personal phone number (PPN) to patients for increased accessibility. We investigated participant utilization of provider's PPN, its effect on participant satisfaction, provider's ability to predict abuse of this practice, and evolving provider perceptions.

Study Design: Prospective, randomized study.

Senescence-associated morphological profiles (SAMPs): an image-based phenotypic profiling method for evaluating the inter and intra model heterogeneity of senescence.

Senescence occurs in response to a number of damaging stimuli to limit oncogenic transformation and cancer development. As no single, universal senescence marker has been discovered, the confident classification of senescence induction requires the parallel assessment of a series of hallmarks. Therefore, there is a growing need for "first-pass" tools of senescence identification to streamline experimental workflows and complement conventional markers.
