The effects of regulating interchange fees at cost on the ATM market [PDF]
We show that regulating the interchange fee at cost reduces banks’ incentives to deploy free ATMs over time. Simultaneously, more and more pay-to-use ATMs are deployed by independent ATM deployers. These results are consistent with the recent evolution of the British ATM market.

The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.

Remote Assessment of Ataxia Severity in SCA3 Across Multiple Centers and Time Points
ABSTRACT Objective Spinocerebellar ataxia type 3 (SCA3) is a genetically defined ataxia. The Scale for Assessment and Rating of Ataxia (SARA) is a clinician‐reported outcome that measures ataxia severity at a single time point. In its standard application, SARA fails to capture short‐term fluctuations, limiting its sensitivity in trials.

ABSTRACT Background and Objectives Multiple sclerosis (MS) exhibits racially disparate rates of disease progression. Black people with MS (B‐PwMS) experience a more severe disease course than non‐Hispanic White people with MS (NHW‐PwMS). Here we investigated structural and functional connectivity as well as structure–function decoupling in the ...

Dimethyl Fumarate, But Not Rituximab, Reduces Serum GFAP Levels and PIRMA in Relapsing–Remitting MS
ABSTRACT Objective Serum neurofilament light chain (sNfL) and glial fibrillary acidic protein (sGFAP) levels are believed to reflect mainly acute and chronic disease processes in multiple sclerosis (MS), respectively. In this study, we investigated whether dimethyl fumarate (DMF) and rituximab (RTX) differentially affect these biomarkers.

Approaches to Regulating Interchange Fees in Payment Systems [PDF]
Significant attention worldwide has been paid to the regulation of credit card interchange fees. In part, this attention has followed concerns expressed about the level of these fees in Europe, the U.S. and Australia. The Reserve Bank of Australia recently conducted an extensive inquiry into the interchange fees associated with credit cards and has ...
