Mechanical countermeasures for spaceflight-associated neuro-ocular syndrome during 30-days of head down tilt bed rest: design, implementation, and tolerability

Frontiers in Physiology
After longer duration space missions, some astronauts experience structural and functional changes in the eye and structural changes in the brain, termed Spaceflight-Associated Neuro-Ocular Syndrome (SANS).

Small muscle mass aerobic exercise in health and disease: Unique insights into muscle vascular and metabolic control and performance

Experimental Physiology, EarlyView.
Abstract Studies of small muscle mass exercise (SMME) have revealed that the peripheral O2 transport–utilization cascade is a dynamically regulated system in which perfusive and diffusive components can be selectively amplified, redistributed and mechanically limited depending on contraction pattern, recruitment strategy and intramuscular pressure ...

Numerical simulation of cardiovascular system deconditioning in different microgravity mission scenarios. Risk assessment and countermeasures [PDF]

, 2019
We report results from di¿erent intensive simulations aimed at evaluate the risks involved in a long-term exposure to hypo and hypergravity loads for a very extensive range of possible mission scenarios.

Acute lower leg transcutaneous electrical nerve stimulation increases leg blood flow and exercise capacity in patients with peripheral arterial disease

Experimental Physiology, EarlyView.
Abstract We tested the hypothesis that two different durations of lower leg transcutaneous electrical nerve stimulation (TENS) increase post‐TENS popliteal artery blood flow (PABF), popliteal vascular conductance (PVC), and 6‐min walk distance (6MWD) in patients with peripheral artery disease (PAD).

Non Bayesian Conditioning and Deconditioning [PDF]

, 2010
International audienceIn this paper, we present a Non-Bayesian condition- ing rule for belief revision. This rule is truly Non-Bayesian in the sense that it doesn't satisfy the common adopted principle that when a prior belief is Bayesian, after ...

A Multidimensional approach to Severe Asthma Management: the need for Pulmonary Rehabilitation among candidates for Biologic Therapy

Frontiers in Medicine
BackgroundDespite optimized pharmacological therapy, a significant subset of severe asthma patients remains poorly controlled. Lack of control is often driven by complex, non-inflammatory “treatable traits” that require a multidimensional management ...

Jumping in simulated lunar gravity with blood flow restriction as a potential exercise countermeasure: The acute physiological effects

Experimental Physiology, EarlyView.
Abstract The present study examined the cardiovascular, metabolic, neuromuscular and perceptual effects of low‐intensity jumping in simulated lunar gravity (∼20% bodyweight) with blood flow restriction (BFR). Fourteen healthy adults (24 ± 4 years; 1.81 ± 0.06 m; 75 ± 12 kg) completed an incremental jumping test in simulated lunar gravity (9.5° head‐up ...

Putting the brakes on muscle growth: Myostatin as regulator of disuse atrophy

Experimental Physiology, EarlyView.
Abstract Skeletal muscle is a highly plastic tissue that rapidly adapts to changes in mechanical loading and metabolic activity. Periods of inactivity, including bed rest, limb immobilization or microgravity, induce a pronounced loss of muscle mass and function.
