In this work we calculated the ionic interactions between adjacent amphipathic helices of apo A-I and apo A-IV. The calculation of the electrostatic potential around the helices helps identify the charged residues susceptible to form salt bridges between adjacent helices. An estimation of the stability of the different pairs of helices is derived from the calculation of the energy of interaction between contiguous helices at a water/lipid interface after energy minimization. The most stable energetic conformation corresponds to the 17-residue helices oriented anti-parallel and separated by a stretch of 5 residues in an extended beta-strand conformation, as calculated through the 'stereo alphabet' calculation procedure. In a pair of helices, the hydrophobic faces are directed towards the lipid core of the discoidal phospholipid-apolipoprotein complex and the hydrophobic lipid-protein interactions are major determinants for the stability of the complex. Interactions between polar residues located on the opposite face of the helix and water molecules can also contribute to the overall energy of the system. Finally, salt bridge formation between residues of opposite charge along the edge of the helical segments contribute to the cooperativity of the phospholipid-apolipoprotein complex formation. The mode of assembly of the amphipathic helical repeats of the apolipoproteins around the edge of a discoidal complex is therefore determined both by the hydrophobic character of the residues and by the charge complementarity along the edge of the helices which increases the structural stability and determines the relative orientation of the helices.

The HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelet count) is a clinical expression of a multilayered disease whose central pathophysiology is abnormal placentation. Clinical research aims logically to search for new predictive and specific markers for the early identification of pregnant women at risk of developing a HELLP syndrome, the most common cause of feto-maternal mortality and morbidity.

M cells represent a potential portal for oral delivery of peptides and proteins due to their high endocytosis abilities. An in vitro model of human FAE (co-cultures) was used to evaluate the influence of M cells on the transport of free and encapsulated helodermin - a model peptide - across the intestinal epithelium. M cells enhanced transport of intact helodermin (18-fold, Papp 3 X 10(-6) cm s(-1)). As pegylation increased nanoparticle transport by M cells, helodermin was encapsulated in 200 mu nanoparticles containing PEG-b-PLA:PLGA 1:1. Stability of the selected formulation was demonstrated in simulated gastric and intestinal fluids. M cells increased the transport of helodermin encapsulated in these nanoparticles by a factor of 415, as compared to Caco-2 cells. Transport of free and encapsulated helodermin occurred most probably by endocytosis. In conclusion, M cells improved helodermin transport across the intestinal epithelium, confirming their high potential for oral delivery of peptides. [less ▲]

A 12-year old female, suffering from recurring episodes of icterus and abdominal pain, is hospitalized in emergency. She is not anemic but her hemogram reveals a high level of hyperdense red blood cells (32%; controls 0-2.5%) and an abnormal reticulocyte count (201 x 10(3)/microL; controls 29-84 x 10(3)/microL), indicating a 3.5 fold increase in RBC production. The same abnormalities are found in the patient's mother. The blood smear shows few spherocytes. RBC osmotic fragility is increased only after incubation. Hereditary spherocytosis is diagnosed following electrophoresis of membrane proteins which reveals a deficiency in band 3, a protein which links the lipid bilayer to the cytoskeleton. This case of hemolytic anemia-illustrates the physiopathologic and diagnostic significance of hyperdense RBC, which reflect the cell dehydration associated with the membrane disorder. [less ▲]

Spontaneous spinal extradural hematomas are rare entities, especially during pregnancy. The authors report a case of a 26 years old women who developed as Brown-Sequard syndrome during pregnancy. The patient underwent first a caesarean and thereafter a prompt spinal surgical decompression. Complete sensory-motor recovery occurred after 48 hours. Differential diagnosis of cord compression, etiology of bleeding, conditions of recovery after surgery are discussed. [less ▲]
