Objectives: All over the world, attempts are made at early prediction of disease severity ongoing COVID-19 pandemic and catching those patients who likely to develop severe may undergo cytokine storm. Though clinical laboratory parameters mainstay in diagnosing oxygen requirements, high resolution computed tomographic (HRCT) scanning chest is one such promising tool help identify a subset very ...

It is shown that oxygen is not absolutely needed for stress-induced synthesis of catalase T in the yeast Saccharomyces cerevisiae. Yeast cells develop heat resistance after exposure to elevated temperatures in anoxia. The levels of catalase activity and thermotolerance are comparable to those in aerobically stressed cells. While these results obviously do not exclude a stress signaling role of ...

In March 1979 there was an explosion in a coalmine in Lancashire. As a result three men were found dead down the mine and a further seven men, all with extensive burns, died between the third and thirteenth day after the explosion. The lungs were studied in all the cases. Pulmonary infection was the commonest cause of death. Despite high levels of oxygen being given to these seven men, only one...

OBJECTIVE To identify risk factors for mortality in neonates with meconium aspiration syndrome. METHODS All neonates (2004-2010) with meconium aspiration syndrome, irrespective of gestation were included. Risk factors were compared between those who died and survived. RESULTS Out of 172 included neonates, 44 (26%) died. Mean (SD) gestation and birth weight were 37.9 (2.3) weeks and 2545 (64...

Rat-liver cinnabarinate synthase (3-hydroxyanthranilic acid-oxygen oxidoreductase) was partially purified. Stoicheiometric studies indicated the consumption of 3 atoms of oxygen/molecule of cinnabarinic acid formed. There was an initial lag in enzyme activity. The reaction had an optimum pH about 7-2 and an optimum temperature of 37°. The enzyme was highly specific for 3-hydroxyanthranilic acid...

The energy system analysis of an integrated process producing synthetic natural gas (SNG) from woody biomass has been carried out. Two different configurations have proposed and modeled, considering the integration between gasification, solid oxide electrolysis (SOEC) catalytic reactors for methane synthesis. two investigated differ in size SOEC unit. In first configuration, unit is sized to in...

of 100% oxygen during induction and emergence is standard practice for the vast majority of anesthetists, our study reflects the impact of high intraoperative inspired oxygen in actual practice. The use of 100% oxygen for induction and emergence also likely had minimal effect on our results because the degree of atelectasis induced by administration of 100% oxygen for only a few minutes is rela...

AIM To determine whether extubation to nasal continuous airway pressure (NCPAP) results in a greater proportion of infants remaining free of additional ventilatory support for one week after extubation compared with those extubated directly to headbox oxygen. METHODS A randomised, controlled, clinical trial was conducted at the neonatal intensive care unit of the Royal Women's Hospital, Melbo...

BACKGROUND Progesterone has long been known to have central effects, by reduced anaesthetic requirements as measured by minimum alveolar concentration (MAC) in various settings. However, other studies have contradicted these findings. Therefore, we compared the effect of progesterone on anaesthetic requirements in a mouse model. METHODS Male C57BL/6 mice were treated with either progesterone ...

The purpose of this study was to comparatively investigate the energy expenditure of jumping on sand and on a firm surface. Eight male university volleyball players were recruited in this study and performed 3 sets of 10 repetitive jumps on sand (the S condition), and also on a force platform (the F condition). The subjects jumped every two seconds during a set, and the interval between sets wa...
