Mrp1 is involved in lipid presentation and iNKT cell activation by Streptococcus pneumoniae

The CD1d pathway present lipid antigens resulting in the activation of iNKT cells but the complete pathway remains to be fully elucidated. Here, Chandra et al. use an siRNA screen and identify Mrp1 as crucial for CD1d lipid presentation and activation of iNKT in the context of Streptococcus pneumoniae infection

Regulation of intracellular free arachidonic acid in Aplysia nervous system

We have studied the regulation of arachidonic acid (AA) uptake, metabolism, and release in Aplysia nervous system. Following uptake of [ 3 H]AA, the distribution of radioactivity in intracellular and extracellular lipid pools was measured as a function of time in the presence or absence of exogenous AA. The greatest amount of AA was esterified into phosphatidylinositol (relative to pool size). We found that the intracellular free AA pool underwent rapid turnover, and that radioactive free AA and eicosanoids were released at a rapid rate into the extracellular medium, both in the presence and absence of exogenous AA. Most of the released radioactivity originated from phosphatidylinositol.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/48020/1/232_2005_Article_BF01868464.pd

Frequency of vital sign measurement among intubated patients in the general ward and nurses’ attitudes toward vital sign measurement

Tadashi Kamio,1 Ayako Kajiwara,2 Yusuke Iizuka,1 Junji Shiotsuka,1 Masamitsu Sanui11Department of Anesthesiology and Critical Care Medicine, Jichi Medical University Saitama Medical Center, Saitama, Japan; 2Department of Nursing, Jichi Medical University Saitama Medical Center, Saitama, JapanPurpose: The lack of recognition of respiratory distress may result in emergency tracheal intubation in the general ward. However, few studies have examined the differences in the frequency of vital sign measurement between patients with and without emergency tracheal intubation in the general ward. Thus, this study aimed to investigate the differences in the frequency of vital sign measurements between patients with and without emergency tracheal intubation.Patients and methods: This is a single-center, retrospective, observational study of unplanned intensive care unit (ICU) admissions from the general wards between December 2015 and February 2017. This study included patients with emergency medical intubations in the general ward who were then transferred to the ICU. Vital signs measured within 24 hours prior to ICU admission were compared between patients who did and did not require emergency tracheal intubation in the general ward. A survey was also conducted to explore the nurses’ attitudes toward vital sign measurements.Results: Compared with other vital signs, the respiratory rate was significantly less frequently measured. Moreover, the frequency of respiratory rate measurement was lower in the 38 patients who were intubated than in the 102 patients who were not intubated in the general ward (P=0.07). The survey revealed that 54% of the participating nurses considered assessment of the respiratory rate as the most troublesome nursing task and ~15% of nurses did not routinely measure respiratory rates.Conclusion: Respiratory rate was less frequently assessed in deteriorating patients in the general ward, possibly because it was considered a troublesome task. Keywords: emergency intubation, vital sign measurements, general ward, nurse’s attitudes toward vital signs, respiratory rat
