Bilateral Cryptococcal Choroiditis in a Human Immunodeficiency Virus-Infected Patient: A Case Report.

Introduction: In this case report, we present a rare case of bilateral cryptococcal choroiditis following a diagnosis of meningitis in a 38-year-old woman with HIV.

Case Presentation: A Colombian woman, newly diagnosed with HIV, presented with respiratory distress followed by meningeal syndrome. Further evaluation revealed cryptococcal meningitis caused by , confirmed through cerebrospinal fluid analysis and brain magnetic resonance imaging.

Complex coacervation of whey proteins and gum arabic.

Mixtures of gum arabic and whey protein (whey protein isolate, WP) form an electrostatic complex in a specific pH range. Three phase boundaries (pH(c), pHphi(1), pHphi(2)) have been determined using an original titration method, newly applied to complex coacervation. It consists of monitoring the turbidity and light scattering intensity under slow acidification in situ with glucono-delta-lactone.

Microencapsulation: its application in nutrition.

The development of new functional foods requires technologies for incorporating health-promoting ingredients into food without reducing their bioavailability or functionality. In many cases, microencapsulation can provide the necessary protection for these compounds, but in all cases bioavailability should be carefully studied. The present paper gives an overview of the application of various microencapsulation technologies to nutritionally-important compounds, i.

Stabilization of Solutions of Feather Keratins by Sodium Dodecyl Sulfate.

Feather keratins were extracted from chicken feathers with aqueous solutions of urea and 2-mercaptoethanol. After filtration of the insoluble residue, a feather keratin solution was obtained. Removal of 2-mercaptoethanol and urea by dialysis resulted in aggregation of the keratin polypeptide chains and oxidation of the cysteine residues to afford a gel.
