Increased acidophilia of eosinophil granules after EDTA treatment
1986
The acidophilic reaction of eosinophil leucocyte granules from human, pig and horse blood smears was investigated by using May-Grünwald-Giemsa staining after previous treatment with EDTA and sodium citrate solutions. The same peak at 530 nm, but absorption values considerably higher than those of controls, were found in eosinophil granules after application of chelating agents, indicating that removal of metal cations could unmask basic groups in these structures.

A conservative treatment for eosinophilic cystitis
2022
Introduction: Eosinophilic cystitis is a rare condition which causes common symptoms and may mimic other conditions. Eosinophilic cystitis has several causes such as hypereosinophilic syndrome, inflammatory diseases, neoplasia, parasites or fungal infection, IgE-related diseases, Drug Reaction and Eosinophilia and Systemic Symptoms (DRESS) syndrome, or Churg-Strauss syndrome. Therefore, differential diagnosis is difficult. Case presentation: We report the case of a middle-aged man affected by eosinophilic cystitis with persistent hematuria and other peculiar symptoms that may be brought back to hypereosinophilic crisis. Conclusion: Conservative approach is preferred, avoiding radical cystec…
New Sperm Morphology Analysis in Equids : Trumorph ® Vs Eosin-Nigrosin Stain
2021
Equine Reproduction Service. Department of Animal Medicine and Surgery. Veterinary Faculty. Autonomous University of Barcelona. National Agency for Research and Development (ANID), Ministry of Education, Chile (2017/72180128). Secretary of Higher Education, Science, Technology and Innovation (SENESCYT)(CZ02-000507-2019) The evaluation of the male fertility potential is based on the analysis of the basic spermatic characteristics of concentration, motility and morphology. Thus, the study of sperm morphology is a fundamental element in the seminal analysis, but its real meaning has been biased by the techniques used for its evaluation. These techniques involve dehydration phases and subsequen…
Energy transfer to xanthene dyes in dansylated POPAM dendrimers
2011
Abstract Excitation energy transfer (EET) in host–guest complexes of dansylated POPAM dendrimers and xanthene dyes have been studied by transient absorption spectroscopy. EET from dansyl periphery to guests: rose bengal, eosin, or fluorescein, showed non-exponential behaviour as a result of distribution of donor–acceptor distances. Time constants range from 100 fs to 8 ps, independent of the dye and the dendrimer generation. Experiments suggested that in dendrimers binding more than one guest, EET among the guests becomes effective. Guest–host and guest–guest interactions induce non-radiative relaxation channels making excitation decays of the guests clearly faster in complexes than in solu…
Endotyping allergic rhinitis in children: A machine learning approach.
2021
Introduction: The diversity of allergic rhinitis (AR) phenotypes is particularly evident in childhood, suggesting the need to analyze and identify new approaches to capture such clinical heterogeneity. Nasal cytology (NC) is a very useful diagnostic tool for identifying and quantifying nasal inflammation. Data-driven approaches such as latent class analysis (LCA) assign subjects to classes based on their characteristics. We hypothesized that LCA based on NC, including the assessment of neutrophils, eosinophils, and mast cells, may be helpful for identifying AR endotypes in children. Methods: A total of 168 children were enrolled. Sociodemographic characteristics and detailed medical history…
Comparing tacrolimus ointment and oral cyclosporine in adult patients affected by atopic dermatitis: a randomized study
2004
BACKGROUND: Atopic dermatitis (AD) is a chronic allergic inflammatory disease, which manifests itself with eczematous skin lesions. OBJECTIVE: We compared the clinical efficacy of tacrolimus ointment (0.1%) given twice a day and oral cyclosporine (3 mg/kg) given once daily. Rescue medication for itching included cetirizine 10-20 mg (equal to one or two tables). METHODS: Thirty patients, aged 13-45 years (mean+/-SD 27.1+/-10.9), with a history of moderate-to-severe AD were randomized to treatments, 15 patients for each treatments. Assessment of efficacy was based on SCORAD, on scores of daily itching, erythema, interference with sleep, due to the skin condition and days without use of cetiri…
Initiation and Modulation of ECF Generation and Secretion from Human Polymorphonuclear NeutrophilsX.
1978
The primary mediators which are involved in inflammatory processes are histamine, the slow reacting substance of anaphylaxis (SRS-A), the platelet aggregating factor (PAF) and the eosinophil chemotactic factor (ECF). These mediators are primarily localized within mast cells and basophil leucocytes, which represent the target cells of allergic reaction. Binding of IgE to mast cells and basophil leucocytes and addition of the appropriate antigen then leads to the activation of the target cells with a subsequent release of their mediators. SRS and ECF have also been found in a non mast cell source, e.g. in human PMNs. ECF can be generated and released from human PMNs by different stimuli, such…
