Transport and inhibition of the sphingosine-1-phosphate exporter SPNS2.

Sphingosine-1-phosphate (S1P) is a signaling lysolipid critical to heart development, immunity, and hearing. Accordingly, mutations in the S1P transporter SPNS2 are associated with reduced white cell count and hearing defects. SPNS2 also exports the S1P-mimicking FTY720-P (Fingolimod) and thereby is central to the pharmacokinetics of this drug when treating multiple sclerosis.

Heart-brain microvascular MRI study: protocol for a multicentre, observational, cohort study in the UK assessing associations between small vessel disease of the heart and brain.

Introduction: Ischaemic heart disease (IHD) and cerebrovascular disease are leading causes of morbidity and mortality worldwide. Cerebral small vessel disease (CSVD) is a leading cause of dementia and stroke. While coronary small vessel disease (coronary microvascular dysfunction) causes microvascular angina and is associated with increased morbidity and mortality.

The fluid dynamics of a viscoelastic fluid dripping onto a substrate.

Extensional flows of complex fluids play an important role in many industrial applications, such as spraying and atomisation, as well as microfluidic-based drop deposition. The dripping-on-substrate (DoS) technique is a conceptually-simple, but dynamically-complex, probe of the extensional rheology of low-viscosity, non-Newtonian fluids. It incorporates the capillary-driven thinning of a liquid bridge, produced by a single drop as it is slowly dispensed from a syringe pump onto a solid partially-wetting substrate.

Polymedia Literacy and Other Ethical Considerations for Online Ethnographic Research on Social Networking Sites.

Drawing on the authors' own ethnographic research, this article discusses the importance of developing polymedia literacy as a key step toward ethical online research on social networking sites (SNS). Polymedia literacy entails the ability to critically analyze the vast landscape of SNS, their affordances, and users' social motivations for choosing specific SNS for their interactions. Internet researchers face several ethical challenges, including issues of informed consent, "public" and "private" online spaces, and data protection.

The importance of adding unbiased Argo observations to the ocean carbon observing system.

The current coverage of direct, high-quality ship-based observations of surface ocean pCO includes large gaps in time and space, and has been declining since 2017. These ocean observations provide the basis for the data products that reconstruct surface ocean pCO and estimate ocean carbon uptake. Improved data coverage is needed to advance our understanding of the ocean carbon sink and air-sea CO exchange.
