Anopheles gambiae, the major vector for the protozoan malaria parasite Plasmodium falciparum, mounts powerful antiparasitic responses that cause marked parasite loss during midgut invasion. Here, we showed that these antiparasitic defenses were composed of pre- and postinvasion phases and that the preinvasion phase was predominantly regulated by Rel1 and(More)
STUDY OBJECTIVES To determine whether bedside endovaginal sonography (EVS) performed by emergency physicians reduces complications associated with ectopic pregnancy (EP) including missed EP and EP rupture. METHODS Our setting was an urban trauma center emergency department. We assembled a prospective convenience sample (n=314) with a historical EP control(More)
The double laser beam diffraction of spherized RBC used in the ADVIA 120 haematological analyser allows quantitation of cells aberrant not only by their volume but also by their haemoglobin concentration. The present investigation provides arguments for the identification of hyperchromic RBC as spherocytes, mainly the close relation between % hyperchromic(More)
OBJECTIVE To determine a discriminatory level for serum progesterone (SP) in pregnant patients with no definite intrauterine pregnancy (IUP) on endovaginal ultrasonography (US) in the differentiation of ectopic pregnancy from normal IUPs. METHODS A prospective observational study in a convenience sample of women at risk for ectopic pregnancy was performed(More)
Mosquito infections with natural isolates of Plasmodium falciparum are notoriously variable and pose a problem for reliable evaluation of efficiency of transmission-blocking agents for malaria control interventions. Here, we show that monoclonal P. falciparum isolates produce higher parasite loads than mixed ones. Induction of the mosquito immune responses(More)
Anopheline mosquitoes are the only vectors of human malaria worldwide. It is now widely accepted that mosquito immune responses play a crucial role in restricting Plasmodium development within the vector; therefore, further dissection of the molecular mechanisms underlying these processes should inform new vector control strategies urgently needed to roll(More)
This report presents the first case in which glucagon administration enabled the removal of an impacted orogastric tube in a patient with distal esophageal spasm. For patients in whom the removal of a gastric tube is impeded, we suggest initially determining tube position and checking for any knotting or kinking of the tube using fluoroscopy. Provided that(More)

Early diagnosis of ectopic pregnancy (EP) continues to be problematic for emergency physicians. With the increasing availability of endovaginal ultrasonography (EVS) for emergency physicians, recognizing additional EVS findings, ie, the presence of a tubal ring, in patients with risk factors or clinical presentation for EP can assist the emergency physician(More)
