Some shallow water benthic foraminifera are able to retain functional chloroplasts (kleptoplasts) from their food source, i.e. diatoms. Here we assessed the functionality of the kleptoplast xanthophyll cycle (XC, i.e. the main diatom short-term photo-regulation mechanism) and we surveyed Haynesina germanica kleptoplast pigment composition over time and at different light regimes. Six common dia...

 The aim of me present work was to investigate rhe potential utility of nanoparticles made of chitosan (CS) and also CS chemically modified with polyethylene glycol (CS-PEG) as new vehicles for improving na^al vaccine delivery. For mis purpose, diphtheria toxoid (DT) was chosen as a model antigen. DT was entrapped within nanoparticles made of CS of different molecular weight, and also made of C...

BACKGROUND AND PURPOSE This study examines if involvement of the lenticulostriate arteries (LSAs) in MCA stroke and consecutive infarction of the basal ganglia can be predicted by the exact occlusion site, as determined in pre-interventional CT or MRI imaging. METHODS Retrospective analysis of 212 patients with acute isolated MCA occlusions treated with mechanical thrombectomy. The occlusion ...

The objective was to develop surfactant-based vesicle formulations containing diphtheria toxoid (DT) for transcutaneous immunization. Formulation variables were molar ratio of the surfactants (sucrose-laurate ester, octaoxyethylene-laurate ester, and sodium bistridecyl sulfosuccinate), DT concentration, pH, and ionic strength. The formulations were characterized by visual inspection, dynamic li...

We evaluated the reactogenicity and immunogenicity of a booster dose of diphtheria-tetanus vaccine administered at the age of school-entry, comparing a low-dose vaccine (dT) to the standard paediatric dose (DT). Participants were randomly assigned to receive one of the two vaccines; the study was evaluator-blinded. The frequency of side-reactions was similar when comparing the two groups, excep...

The study aimed at assessing and estimating the fatigue resistance of different fiber posts and to observe their ultrastructures through SEM. Six types of fiber posts were used: GC Fiber Post (Group 1), ParaPost Fiber White (Group 2), FibreKor (Group 3), DT Light-Post radiopaque (Group 4), FRC Postec (Group 5), and Luscent Anchors (Group 6). Ten out of 15 posts within each group were used for t...

OBJECTIVE The effects of closely adapting a prefabricated fiber to the post space remain unknown. The purpose of this study was to quantify the microleakages of a custom adapted fiber-reinforced post, a prefabricated quartz fiber post and a cast post using nondestructive methods. MATERIALS AND METHODS Sixty-five extracted human premolars were endodontically treated and randomly divided into t...

Two formulations of spinosad, direct application tablet (DT) and 0.5% granules (GR), at 3 dosages (0.25, 0.5 and 1.0 mg/l) in 200-liter earthen jars were evaluated against the larvae of Aedes aegypti. Two water regimens were used in the jars: jar full all the time and a full jar in which half the volume of the water was removed and replaced at each assessment interval. All treatments and contro...

Alcoholism is common among trauma patients and often lacks the appropriate monitoring. Alcohol withdrawal syndrome (AWS), including delirium tremens (DT), can be associated with significant postoperative morbidity and mortality. However, appropriate acute pain management may protect against delirium; the administration of intravenous patient-controlled analgesia (IV - PCA) may not only alleviat...
