N exchanges in hyperbaric environments: toward a model based on physiological gas transport (O and CO).

Decompression sickness can occur in divers even when recommended decompression procedures are followed. Furthermore, the physiological state of individuals can significantly affect bubbling variability. These informations highlight the need for personalized input to improve decompression in SCUBA diving.

Megaesophagus in an 8-month-old cat secondary to a laryngomucocele.

Case Summary: An 8-month-old spayed female cat presented with a 7-week history of progressive dyspnoea, dysphagia and regurgitation. Plain radiography revealed megaoesophagus with a large, rounded, soft tissue opacity laryngeal mass. Endoscopic examination revealed a fluid-filled lesion, which was lanced and drained completely.

Skin temperature influence on transcutaneous carbon dioxide (CO) conductivity and skin blood flow in healthy human subjects at the arm and wrist.

present transcutaneous carbon dioxide (CO)-tcpCO-monitors suffer from limitations which hamper their widespread use, and call for a new tcpCO measurement technique. However, the progress in this area is hindered by the lack of knowledge in transcutaneous CO diffusion. To address this knowledge gap, this study focuses on investigating the influence of skin temperature on two key skin properties: CO permeability and skin blood flow.

Blood phenylalanine fluctuation in phenylketonuric children treated by BH4 or low-phenylalanine diet from birth.

The prognosis of phenylketonuria (PKU) is related to the quality of metabolic control all life-long. PKU treatment is based on a low-Phe diet, 6R-tetrahydrobiopterin (BH4) treatment for the BH4-responsive PKU patients or enzyme replacement therapy. Fluctuations in blood phenylalanine (Phe) concentrations may be an important determinant of intellectual outcome in patients with early and continuously treated phenylketonuria (PKU).

Comparison of Sodium Selenite and Selenium-Enriched Spirulina Supplementation Effects After Selenium Deficiency on Growth, Tissue Selenium Concentrations, Antioxidant Activities, and Selenoprotein Expression in Rats.

Selenium contributes to physiological functions through its incorporation into selenoproteins. It is involved in oxidative stress defense. A selenium deficiency results in the onset or aggravation of pathologies.
