Abstract Background Patients with fibromyalgia (FM) exhibit low peak oxygen uptake ( $$\dot{\text{V}}$$ V ˙ O2peak). We aimed to detect the contribution of cardiac output to ( $$\dot{\text{Q}}$$ Q ˙ ) and arteriovenous oxygen difference $$[\text{C}

Identification of a D-galacturonate reductase efficiently using NADH as a cofactor

Autor: Kaisa E. Peltonen, Peter Richard

Publikováno v: Biotechnology Reports, Vol 35, Iss , Pp e00744- (2022)

D-galacturonate reductases are catalysing the reversible reduction of D-galacturonate to L-galactonate using NAD(P)H as a cofactor. The enzymes are part of two different pathways. One pathway is the fungal pathway for the catabolism of the main compo

Purpose To investigate whether 4 weeks of normobaric “live high–train low and high” (LHTLH) causes different hematological, cardiorespiratory, and sea-level performance changes compared to living and training in normoxia during a preparation se

The orange peel waste is essentially an important residue in many countries, representing more a problem than one opportunity. Most of this residue processing is related to low added value products and it includes the generation of other residues. Am

ObjectiveIf the body fails to acclimatize at high altitude, acute mountain sickness (AMS) may result. For the early detection of AMS, changes in cardiac autonomic function measured by heart rate variability (HRV) may be more sensitive than clinical s
