Insufficient ventilation as a cause of impaired pulmonary gas exchange during submaximal exercise

, 2007
Pulmonary ventilation and gas exchange were determined during prolonged skiing (approximately 76% of V(O2, max); cardiac output=26-27 L min(-1)) using diagonal technique (DIA) for 40 min followed by 10 min of double poling (DPOL) and 10 min of leg skiing

Cyanogenic Compounds, Physicochemical Parameters and Metals in Water From Cassava Processing Areas: A Study in the Brazilian Amazon, Using Multivariate Analysis

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the water quality of artesian wells and effluents generated in cassava processing in a rural area of Bragança, Pará, with emphasis on physicochemical parameters, multielement composition, and cyanogenic compounds. The well water presented specific nonconformities, highlighting pH values below the recommended level and high

Microplastics and the Endocrine–Metabolic Interface: Novel Diagnostic Tools Targeting Thyroid–Adipose Axis

Environmental Toxicology, EarlyView.
ABSTRACT Microplastics (MPs) have been identified as major environmental contaminants that can affect organisms directly and act as carriers of particles and chemical additives, thereby aggravating endocrine networks that coordinate metabolic homeostasis.

Influence of ACE-inhibition on salt-mediated worsening of pulmonary gas exchange in heart failure

, 2001
In congestive heart failure (CHF), pulmonary gas exchange, as evaluated by carbon monoxide diffusion (DLCO), is impaired. ACE-inhibition improves DLCO.

Effect of butorphanol in combination with xylazine during castration of calves: A randomised trial under field conditions

Veterinary Record, EarlyView.
Abstract Background In horses, cats and dogs, the opioid butorphanol has been proven effective in management of visceral pain and for peri‐ and postoperative pain relief. The aim of this study was to evaluate physiological responses and indicators of noxious stimuli when adding butorphanol to xylazine for sedation of bull calves during surgical ...

Pulmonary function and exercise testing in adult survivors of congenital diaphragmatic hernia

Congenital diaphragmatic hernia (CDH) is accompanied by pulmonary hypoplasia and structural abnormalities of the pulmonary vascular bed. It is unknown whether pulmonary function, exercise capacity, and gas exchange during exercise are impaired in adult ...

Augmented diffusion in the airways can support pulmonary gas exchange

, 1980
Bohn et al. (J Appl. Physiol.: Respirat. Environ. Exercise Physiol, 48: 710-716, 1980) reported that paralyzed beagle dogs maintained normal gas exchange for 6 h or more when small tidal volumes at high breathing rates were maintained at the airway ...

Staging concept for aging management: Definition, mechanism, and coping strategies

VIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...
