Puroindolines, for years largely investigated for their involvement in wheat kernel hardness, have recently attracted attention thanks to their possible role as antimicrobial proteins. With the aim to enhance our knowledge of these proteins we studied their localization in the kernel, and their antimicrobial activity in vitro against six different bacterial(More)
BACKGROUND Posterior Reversible Encephalopathy (PRES) is characterized by acute-onset headache, altered mental status, cortical blindness and seizures, with parietal-occipital involvement. We report all cases of PRES diagnosed in our intensive care unit during the last 4 years, and evaluate their outcome in terms of the different medical treatments used.(More)
Puroindolines are antimicrobial peptides that occur in wheat seed, and are characterized by broad antimicrobial activity. We describe the heterologous expression of puroindoline A and B in the Origami strain of Escherichia coli. The recombinant puroindolines showed the same antimicrobial activity on Staphylococcus epidermidis as compared to the native(More)
Puroindoline A and puroindoline B from plant seeds, bovine lactoferrin and chicken eggs lysozyme are antimicrobial proteins of innate immune system that lyse invading organisms. We investigate their potential antibacterial activity against Listeria monocytogenes in a mouse model. Bacteria were isolated from various organs for 7 days after challenge. Livers(More)
Antimicrobial peptides and proteins are being studied with increasing interest because of their broad range antimicrobial activity. Among plant antimicrobial proteins, the wheat seed polypeptides, puroindoline a and puroindoline b, are particularly interesting because of their established antibacterial activity. In this paper we describe different(More)
Lactoferrin (LF) is a member of the transferrin family of iron-binding glycoproteins. It is also a multifunctional protein of 80 kDa that is synthesized by glandular epithelial cells and secreted into mucosal fluid. High levels of LF are present in colostrom and milk and low levels in tears, saliva, and gastrointestinal and reproductive secretions. Data(More)
BACKGROUND Mannose-binding lectin (MBL) activates the complement system in an antibody-independent manner, enhances complement-mediated phagocytosis, and plays a major role in the regulation of inflammatory cytokine release by monocytes. METHODS Case patients (277 patients with pulmonary tuberculosis) and control subjects (288 household contacts) were(More)
Patients (305 patients with pulmonary tuberculosis) and controls (290 household genetically unrelated contacts) were tested by polymerase chain reaction (PCR) for polymorphisms in the intron 15 and the 5' untranslated region of the gene coding for the a3 isoform of the human ATPase gene. Diagnosis of pulmonary tuberculosis was based on chest radiography and(More)
The old Annurca apple cultivar (Malus domestica), particularly appreciated for its peculiar flavor and crispy flesh, was studied in order to preserve its ancient germplasm. Twelve clones of Annurca were analyzed using random amplified polymorphic DNA (RAPD) and simple-sequence repeat (SSR) markers. Two out of 30 RAPD primers and nine out of ten SSR primers(More)
Among all diverticula of the esophagus, epiphrenic diverticula occur less frequently than those in the pharyngo-esophageal segment. Two simultaneously occurring diverticula in the epiphrenic esophagus are very rarely reported in the English literature. A 52-year-old woman had a 3-year history of troublesome dysphagia, heartburn, chest pain and cough.(More)
