Assessment of urinary dipstick in patients admitted to an ED for blunt abdominal trauma.

Introduction: Clinicians still face significant challenge in predicting intra-abdominal injuries in patients admitted to an emergency department for blunt abdominal trauma. This study was thus designed to investigate the value of dipstick urinalysis in patients with blunt abdominal trauma.

Methods: We performed a retrospective, multicenter, cohort study involving patients admitted to the emergency department for abdominal traumas, examined by means of urinary dipstick and abdominal CT scan.

SV2A and SV2C are not vesicular Ca2+ transporters but control glucose-evoked granule recruitment.

Synaptic vesicle protein 2 (SV2) is expressed in neuroendocrine cells as three homologous isoforms, SV2A, SV2B and SV2C. Ca2+-dependent function in exocytosis has been attributed to SV2A and SV2B, without elucidation of the mechanism. The role of SV2C has not yet been addressed.

[Heme structure in cooperative and noncooperative hemoglobins: study by resonant Raman diffusion].

The modifications of heme sites of hemoglobin, which should occur upon apoprotein alterations (responsible for variations of oxygen affinity), have been examined by Resonnant Raman scattering. The oxygenated (R) and deoxygenated (T) shape of apoprotein do not modify the heme states. The spectral differences between these forms are essentially due to the presence or the absence of the sixth ligand.
