Exercise & cardiopulmonary physiology in rheumatoid arthritis
… at the cardiopulmonary exercise tolerance test (CPET) in RA, to confirm the attainment of maximal effort, (3) evaluate potential differences between RA individuals and non-RA controls regarding the cardiopulmonary physiology and its association with the cardiorespiratory fitness (CRF) level and …

Identification and Characterization of a New Class of Bilin Lyases in Synechococcus sp. PCC 7002
… identified in Fremyella diplosiphon as cpeS and cpeT. In Synechococcus sp. PCC 7002, there are three cpeS-like genes (named cpcS, cpcU, and cpcV) and one cpeT-like gene (named cpcT). These genes were cloned, overexpressed, and purified from E. coli. The CpcS and CpcU proteins form a 1:1 complex …

CHANGES IN VE/VCO2 SLOPE OVER TIME IN LVAD RECIPIENTS
… Background: Cardiopulmonary exercise testing (CPET) is essential in the evaluation of patients with heart failure (HF), including left ventricular assist devices (LVADs) recipients. Peak oxygen uptake (pVO2) and VE/VCO2 slope are key prognostic parameters, but their values after LVAD …

Obstructive Sleep Apnea Risk in Abdominal Aortic Aneurysm Disease Patients: Associations with Physical Activity Status, Metabolic Syndrome, and Exercise Tolerance
… responses to cardiopulmonary exercise testing (CPET) in elderly patients with AAA disease. Methods: Elderly patients (n=326 for Studies 1 and 2; n=114 for Study 3) newly diagnosed with small AAAs (aortic diameter "2.5 and < 5.5 cm) were recruited. Data collection for all participants included: …

Mechanistic Investigations of Hydrogen and Oxygen Atom Transfer Reactions by Manganese-Oxygen Species
… concerted proton electron transfer process (CPET). Likewise, a manganese(III)-hydroxo intermediate in the active site of the Mn-LOX enzyme is proposed to oxidize polyunsaturated fatty acids into hydroperoxides via CPET process. The oxidation of C‒H bonds by high-valent iron(IV)-oxo …

Cardiovascular Functional Alterations in Chronic Kidney Disease
… cardiopulmonary exercise testing (CPET) to examine ventilatory exercise response indices of cardiovascular functional capacity across the CKD spectrum. Using CPET, I first examine cardiovascular functional changes and the determinants involved in patients with mild-to-moderate CKD …

A Comparison of Maximal Exercise Responses among Patients with a Total Artificial Heart, a Left Ventricular Assist Device, or Advanced Heart Failure
… cardiopulmonary exercise testing (CPET) following device implant of either TAH or HMII. ANOVA was performed to compare differences between the two device groups and HF patients listed for heart transplant. Fourteen TAH patients underwent CPET (9 male, 5 female) with peak oxygen …

Characterization of Enzymes Involved in Bilin Attachment to Allophycocyanin in the Cyanobacterium Synechococcus sp. PCC 7002
… cpeS-like genes termed cpcS and cpcU, and one cpeT-like gene termed cpcT. In vitro bilin attachment reactions were conducted in the presence of the recombinant substrate apo-allophycocyanin (HT-ApcAB). Size exclusion HPLC showed that CpcS and HT-CpcU form a 1:1 heterodimeric complex and that …

Identification and Characterization of Enzymes Involved in Post-translational Modifications of Phycobiliproteins in the Cyanobacterium Synechocystis sp. PCC 6803
… are two cpeS-like genes (cpcS and cpcU) and one cpeT-like gene (cpcT). Through absorbance and fluorescence spectra, it was determined that CpcS and CpcU together catalyze the addition of phycocyanobilin to Cys-82 on betaphycocyanin in vitro and that CpcT is a lyase that adds phycocyanobilin to …

Unexplained Exercise Intolerance and Dyspnea in Long COVID
… (HRV), and cardiopulmonary exercise testing (CPET). Participants with long COVID exhibited marked reductions in inspiratory muscle performance—MIP (−52%), SMIP (−71%), and FIT (−79%)—and lower aerobic capacity (VO₂ peak = 21.1 ± 7.2 vs. 30.2 ± 11.0 mL·kg⁻¹·min⁻¹; p = 0.01). FMD was …

A validation and feasibility study of the non-invasive measurement of oxygen delivery and consumption after elective major abdominal surgery.
Major surgery triggers a physiological stress response that results in an increase in post-operative metabolic demand and oxygen consumption (V̇O2), which must be met by an increased oxygen delivery (DO2). Historical studies described the increase in V̇O2 in patients after major surgery and …
