We have studied the temperature of expired air during a maximal forced expiratory manoeuvre, because this has not previously been fully investigated and it will influence how flow and volume recording devices should be calibrated and used. Temperature was recorded with a fine thermocouple, the response time of which was determined at various gas velocities and for which a correction was made. R...

We have found an increased H2O2 level in expired air of asthmatic patients. Neutrophils from these subjects generated higher amounts of superoxide radicals after challenge with phorbol esters than those from healthy subjects which may result from an increased activity of NADPH-oxidase. The enhanced Ca2+ mobilisation in neutrophils from asthmatics could be responsible for increased production an...

The highest increase of damaged or expired drugs at Karangmalang Healthcare Center in 2020 was 48,060 drugs, caused a stock accumulation. As January to March 2021, it reported that 2,739 were and out during the pandemic. Stock outs stagnant drug could result logistics management not going well. purpose this study determine pharmacy warehouse Pimary Semarang City. Qualitative applied research. i...

Present descriptions of nitric oxide (NO) transport in the lungs use two compartment models: airway compartment without mixing and alveolar compartment with perfect mixing. These models neglect NO molecular diffusion in the airways. To assess the impact of axial diffusion on expired NO profile, we solved a transport equation that incorporated diffusion, convection, and NO sources in the symmetr...

The metabolic fate of [1-(14)C]glucosamine, of N-acetyl[1-(14)C]glucosamine and of glycoproteins labelled with [1-(14)C]glucosamine was studied in rats for a period of 24hr. after these materials were given orally or injected. When [1-(14)C]glucosamine was injected 26.3% of the label was excreted in the urine, 19.7% was expired as carbon dioxide and 12.7% was incorporated into plasma proteins. ...

Red blood cells (RBCs) augment hypoxic pulmonary vasoconstriction (HPV) in part by scavenging of nitric oxide (NO) by Hb (Deem S, Swenson ER, Alberts MK, Hedges RG, and Bishop MJ, Am J Respir Crit Care Med 157: 1181-1186, 1998). We studied the contribution of the RBC compartmentalization of Hb to augmentation of HPV and scavenging of NO in isolated perfused rabbit lungs. Lungs were initially pe...

Abstract We investigate how duration of storage affects food waste behavior. propose and demonstrate a negative impact duration‐of‐storage: even when two packaged products are otherwise identical (i.e., same manufacturing/expiration dates, not expired, unopened), the product that has been stored for longer under current ownership is more likely to be wasted, wasted in greater quantities. This o...
