During constant-power output (PO) exercise above lactate threshold (LT), pulmonary O2 uptake (VO2p) features a developing slow component (VO2pSC). This progressive increase in O2 cost of exercise is suggested to be related to the effects of muscle fatigue development. We hypothesized that peripheral muscle fatigue, as assessed by contractile impairment, would be associated with the VO2pSC. Eleven healthy men were recruited to perform four constant-PO tests at an intensity corresponding to ~60 (very heavy, VH) where is 60% of the difference between LT and peak VO2p.

The slow component of pulmonary O2 uptake accompanies peripheral muscle fatigue during high intensity exercise

Alexandros G. SfakianakisστοPhysiology by Alexandros G.SfakianakisΠριν από 1 ώρα
During constant-power output (PO) exercise above lactate threshold (LT), pulmonary O2 uptake (VO2p) features a developing slow component (VO2pSC). This progressive increase in O2 cost of exercise is suggested to be related to the effects of muscle fatigue development. We hypothesized that peripheral muscle fatigue, as assessed by contractile impairment, would be associated with the VO2pSC. Eleven healthy men were recruited to perform four constant-PO tests at an intensity corresponding to ~60 (very heavy, VH) where is 60% of the difference between LT and peak VO2p.

Analysis of 3-D Tongue Motion From Tagged and Cine Magnetic Resonance Images

Alexandros G. SfakianakisστοΦωνή κ' ΛόγοςΠριν από 1 ώρα
Purpose Measuring tongue deformation and internal muscle motion during speech has been a challenging task because the tongue deforms in 3 dimensions, contains interdigitated muscles, and is largely hidden within the vocal tract. In this article, a new method is proposed to analyze tagged and cine magnetic resonance images of the tongue during speech in order to estimate 3-dimensional tissue displacement and deformation over time. Method The method involves computing 2-dimensional motion components using a standard tag-processing method called harmonic phase, constructing superresolu... περισσότερα »

On Older Listeners' Ability to Perceive Dynamic Pitch

Alexandros G. SfakianakisστοΦωνή κ' ΛόγοςΠριν από 1 ώρα
Purpose Natural speech comes with variation in pitch, which serves as an important cue for speech recognition. The present study investigated older listeners' dynamic pitch perception with a focus on interindividual variability. In particular, we asked whether some of the older listeners' inability to perceive dynamic pitch stems from the higher susceptibility to the interference from formant changes. Method A total of 22 older listeners and 21 younger controls with at least near-typical hearing were tested on dynamic pitch identification and discrimination tasks using synthetic mon... περισσότερα »

Role of WW domain-containing oxidoreductase WWOX in driving T-cell acute lymphoblastic leukemia maturation Immunology

Whether tumor suppressor WWOX stimulates immune cell maturation is largely unknown. Here, we determined that Tyr33-phosphorylated WWOX physically binds non-phosphorylated ERK and IκBα; in immature acute lymphoblastic leukemia MOLT-4 T cell and in the naive mouse spleen. The IκBα/ERK/WWOX complex was shown to localize, in part, in the mitochondria. WWOX prevents IκBα from proteosomal degradation. […]

Asn347-glycosylation of corticosteroid binding globulin fine-tunes the host immune response by modulating proteolysis by P. aeruginosa and neutrophil elastase Protein Structure and Folding

Corticosteroid binding globulin (CBG) delivers anti-inflammatory cortisol to inflamed tissues upon elastase-based proteolysis of the exposed reactive center loop (RCL). However, the molecular mechanisms that regulate the RCL proteolysis by co-existing host and bacterial elastases in inflamed/infected tissues remain unknown. We document that RCL-localized Asn347-glycosylation fine-tunes the RCL cleavage rate by human neutrophil elastase (NE) […]
