Melatonin alleviates Ochratoxin A-induced liver inflammation involved intestinal microbiota homeostasis and microbiota-independent manner.
2021
Melatonin (MEL) shows an anti-inflammatory effect and regulates intestinal microbiota communities in animals and humans; Ochratoxin A (OTA) induces liver inflammation through intestinal microbiota. However, it remains to know whether MEL alleviates the liver inflammation induced by OTA. In this study, MEL reversed various adverse effects induced by OTA. MEL recovered the swarming and motility of intestinal microbiota, decreased the accumulation of lipopolysaccharide (LPS), enhanced the tight junction proteins of jejunum and cecum segments; ultimately alleviated OTA-induced liver inflammation in ducks. However, it is worth noting that MEL still had positive effects on the OTA-exposed ducks a…
Blind recovery of sources for multivariate space-time random fields
2022
AbstractWith advances in modern worlds technology, huge datasets that show dependencies in space as well as in time occur frequently in practice. As an example, several monitoring stations at different geographical locations track hourly concentration measurements of a number of air pollutants for several years. Such a dataset contains thousands of multivariate observations, thus, proper statistical analysis needs to account for dependencies in space and time between and among the different monitored variables. To simplify the consequent multivariate spatio-temporal statistical analysis it might be of interest to detect linear transformations of the original observations that result in stra…
The role of intact oleosin for stabilization and function of oleosomes.
2013
Lipid storage in plants is achieved among all plant species by formation of oleosomes, enclosing oil (triacylglycerides) in small subcellular droplets. Seeds are rich in this pre-emulsified oil to provide a sufficient energy reservoir for growing. The triacylglyceride core of the oleosomes is surrounded by a phospholipid monolayer containing densely packed proteins called oleosins. They are anchored in the triacylglycerides core with a hydrophobic domain, while the hydrophilic termini remain on the surface. These specialized proteins are expressed during seed development and maturation. Particularly, they play a major role in the stabilization and function of oleosomes. To better understand…

2 Section of Hydrobiont Diseases, Pacifi c Research. Fisheries Center, Shevchenko str., 4, Vladivostok, 690950 Russia Taxonomic Status of Neoechinorhynchus agilis (Acanthocephala, Neoechinorhynchidae), with a De- scription of Two New Species of the Genus from the Atlantic and Pacifi c Mullets (Teleostei, Mugili- dae). Tkach, Ie. V., Sarabeev, V. L., Shvetsova, L. S. — Th e wide variability in morphological features, geographical and host ranges of mullet acanthocephalan parasite Neoechinorhynchus agilis (Rudolphi, 1819), raises the question of taxonomic status of this species. Rudolphi's type and Yamagutis voucher specimens, as well as our own material from the WW Pacifi c and NE Atlantic r…
Internal dynamics and energy transfer in dansylated POPAM dendrimers and their eosin complexes.
2010
Internal dynamics of dansylated poly(propyleneamine) dendrimers (POPAM, G1-G4) in solution and excitation energy transfer from dansyls to eosin in POPAM-eosin complexes have been studied by time-resolved fluorescence spectroscopy and molecular dynamics (MD) simulations. Combining the results from fluorescence anisotropy and the MD simulation studies suggests three time domains for the internal dynamics of the G3 and G4 generations, about 60 ps for motions of the outer-sphere dansyls, 500-1000 ps for restricted motions of back-folded dansyls, and 1500-2600 ps for the overall rotation. For the smaller generations, the contribution from the restricted motions was not entirely evident. Eosin bi…
Norm values for eosinophil cationic protein in nasal secretions: influence of specimen collection
1999
Background Eosinophil granulocytes play an important role in allergic inflammation of the nasal mucosa. Eosinophil cationic protein (ECP) is a specific eosinophil granule protein released upon activation of these cells. ECP concentration in nasal secretions has been demonstrated to be a good marker for the activity of eosinophilic nasal mucosal inflammation. The clinical use of such a marker requires defined values which are regarded as pathological or within normal range. In analyses of nasal secretion samples, the sampling method has an important influence on the data obtained. Objective We investigated ECP levels in nasal secretions (NS) of healthy volunteers obtained by seven different …
Comparison of the effects of fluticasone propionate, aqueous nasal spray and levocabastine on inflammatory cells in nasal lavage and clinical activit…
1999
BACKGROUND Treatment options for allergic rhinitis include antihistamines, decongestants, anticholinergics, cromolyn sodium and corticosteroids. As the nose is a small organ, comprising less than 1% of total body mass and surface area, it seems logical to confine treatment of rhinitis to the diseased organ. OBJECTIVE To evaluate the effects of therapy with intranasal fluticasone propionate (FP), both on subjective symptoms and pathophysiological mechanisms, in rhinitis patients during pollen season when the patients were symptomatic. METHODS We used a double-blind, placebo (PLA)-controlled, randomized, double dummy, parallel group study of the effect of 6 weeks treatment. The double-blind c…
Controlled trial for long-term low-dose erythromycin after sinus surgery for chronic rhinosinusitis
2014
Objectives/Hypothesis The efficacy of macrolides in chronic rhinosinusitis (CRS) is still under controversy. To date, only two double-blind, placebo-controlled studies have been published with differing results. None of these studies investigated the possible benefit of macrolides in the postoperative period. We conducted an investigator-initiated clinical trial using 250-mg erythromycin once a day over a period of 3 months, beginning the administration of either erythromycin or placebo 2 weeks after a surgical intervention for CRS. Study Design Randomized double-blind, placebo-controlled trial. Methods The concentrations of eosinophilic cationic protein (ECP) and myeloperoxidase in nasal s…
Mandibulary Eosinophilic Granuloma: Case Series
2008
Eosinophilic granuloma is a proliferation of Langerhans cells in the bones that most commonly involving the skeletal system. The disease generally affects children or young adults with predominance in males and it is characterized by a single or multiple skeletal lesions. This study describes a few cases of mandibular Eosinophilic Granuloma and the effects of surgical curettage of lesions
[Diagnosis in pediatric "allergic" patients].
1998
Background. A clinician who deals with allergic patients needs the help of in vivo and in vitro allergometric tests in order to decide difficult therapeutic choices. Methods. In the section of Clinical Immunology of the Institute of Paediatrics (Palermo University) two allergologic tests, prick and MAST-CIA, have been studied retrospectively, they were performed on patients observed for allergic disorders over 5 years. The aim of this study was to evaluate the diagnostic capacity of these tests "on the field". The study population is made of 459 patients (age range from 6 months to 16 years) affected with asthma, rhinitis, presumably allergic dermatitis, association of asthma and dermatitis…
