Real-time imaging of the medullary circuitry involved in the generation of spontaneous muscle sympathetic nerve activity in awake human subjects

open access: yes, 2008
In order to understand the central neural processes involved in blood pressure regulation we recorded muscle sympathetic nerve activity (MSNA) via a tungsten microelectrode in the common peroneal nerve while performing functional Magnetic Resonance ...

Neuroanatomical and neurofunctional brain basis of cognitive deficits in adolescent subjects who were born preterm. Structural and functional magnetic resonance study [PDF]

open access: yes, 2006
[eng] The general aim of this thesis is to study the cerebral basis of cognitive disturbances in adolescents with history of premature birth (PB). As previous manual volumetric investigations in PB samples, we quantitatively demonstrated the presence of ...

Artificial Intelligence in Systemic Sclerosis: Clinical Applications, Challenges, and Future Directions

open access: yesArthritis Care &Research, EarlyView.
Systemic sclerosis (SSc) is a rare autoimmune disease defined by immune dysregulation, vasculopathy, and progressive fibrosis of the skin and internal organs. Despite advances in care, major complications such as interstitial lung disease (ILD) and myocardial involvement remain the leading causes of morbidity and mortality.

Immunosuppressive Drug Use in Limited Systemic Sclerosis: An International Survey

open access: yesArthritis Care &Research, EarlyView.
Objective Current guidelines recommend immunosuppressive treatment for diffuse cutaneous systemic sclerosis but are less clear on their use in limited cutaneous systemic sclerosis (lcSSc) in the absence of internal organ complications. We conducted an international survey to understand current immunosuppressive drug prescribing patterns in lcSSc ...
