Notch-1 decreased expression contributes to leptin receptor downregulation in nasal epithelium from allergic turbinates

2019

Abstract BACKGROUND: Allergic rhinitis is characterized by a remodeling of nasal epithelium. Since the Notch and TGF-β signaling pathways are known to be involved in cell differentiation and remodeling processes and leptin adipokine has already been identified as a marker for homeostasis in human bronchial and nasal epithelial cells of asthmatics, roles played by these pathways have been investigated for chronic allergic rhinitis. METHODS: The leptin/leptin receptor expression has been investigated in a study with 40 biopsies from allergic (AR, n = 18) and non-allergic (C, n = 22) inferior turbinates, using immunohistochemistry, immunofluorescence staining and RT-PCR. In addition, extracts …

Atrian natriuretic peptide (ANP)-Presence in human inferior turbinate after botulism toxin type A treatment

2012

Studies demomstrated the ANP-presence in the mucosa of human turbinate, the study aimed to investigate about the ANP-presence of human turbinates of patients after treatment with the Botulinum Toxyn-A(BTX-A) since no data are reported. Results show that in BTX-A treated patients ANP is present in the ciliated and basal cells of the epithelium of tonaca mucosa and some glands;therefore ANP-presence is more intense than in mucosa of untreated patients.

Nasal tactile sensitivity in allergic rhinitis

2011

These preliminary data show a decrease in nasal tactile sensitivity and point out interesting aspects of the nasal chronic inflammatory condition in allergic rhinitis.The aim of this study was to evaluate the effects of allergic rhinitis on nasal tactile sensitivity during the intercritical period.A total of 70 patients aged between 18 and 67 years (average 42 years), with a positive history of allergy caused by seasonal outdoor allergens, were included (group A). Patient outcome was assessed by the nasal monofilament test: a set of 20 Semmes-Weinstein monofilaments was used to detect nasal sensitivity for both nasal cavities. The sensitivity threshold was recorded as the minimum monofilame…

Radiofrequency, high-frequency, and electrocautery treatments vs partial inferior turbinotomy: microscopic and macroscopic effects on nasal mucosa.

2009

Objective To compare the microscopic and macroscopic effects of radiofrequency, high-frequency, and electrocautery therapies with partial inferior turbinotomy in the treatment of nasal obstruction caused by inferior turbinate hypertrophy. Design Nonrandomized controlled trial. Setting Department of Otolaryngology–Head and Neck Surgery, University of Genoa. Patients The study included 80 patients affected by nasal obstruction from hypertrophied inferior turbinates. Interventions Homogeneous patient groups A, B, C, and D underwent radiofrequency, high-frequency, and electrocautery treatments and partial inferior turbinotomy, respectively, to surgically reduce hypertrophied inferior turbinates…

Role of adenylate kinase type 7 expression on cilia motility: possible link in primary ciliary dyskinesia.

2010

Background Adenylate kinase 7 (AK7) mediates the reaction 2ADP ↔ ATP + AMP, providing energy for the beating of cilia. A study recently showed that AK7 expression may be correlated with the primary ciliary dyskinesia (PCD) phenotype in mice. In this study, we characterized AK7 expression in vitro in an air–liquid interface (ALI) model and in middle nasal turbinate biopsy specimens from a cohort of patients with PCD to elucidate whether AK7 expression is correlated with ciliary malfunction. Methods AK7 expression was measured by real-time reverse-transcription polymerase chain reaction and Western blotting. In vitro differentiated nasal human epithelial cell siRNA experiments were performed …

Bioactive Constituents of Juniperus turbinata Guss. from La Maddalena Archipelago.

2018

A comprehensive phytochemical study of Juniperus turbinata (Cupressaceae) collected from La Maddalena Archipelago (Sardinia, Italy) is reported. Both the essential oil and the ethanolic extract obtained from the aerial parts were analyzed. The essential oil appears to belong to a new chemotype compared to other Mediterranean juniper accessions, as it was favored by geographic isolation of the isles. It showed a low content of monoterpene hydrocarbons and -terpineol, ent-manoyl oxide, 1,10-di-epi-cubenol as the major constituents. The ethanolic fraction contained mainly diterpenoids. Among these, 15-formyloxyimbricatolic acid (7) is a new natural product since it has hitherto been obtained o…

New chronology for Ksâr ‘Akil (Lebanon) supports Levantine route of modern human dispersal into Europe

2015

Modern human dispersal into Europe is thought to have occurred with the start of the Upper Paleolithic around 50,000-40,000 y ago. The Levantine corridor hypothesis suggests that modern humans from Africa spread into Europe via the Levant. Ksâr 'Akil (Lebanon), with its deeply stratified Initial (IUP) and Early (EUP) Upper Paleolithic sequence containing modern human remains, has played an important part in the debate. The latest chronology for the site, based on AMS radiocarbon dates of shell ornaments, suggests that the appearance of the Levantine IUP is later than the start of the first Upper Paleolithic in Europe, thus questioning the Levantine corridor hypothesis. Here we report a seri…

Phytosociological characterization of the Juniperus phoenicea L. subsp. turbinata (Guss.) Nyman formations in the Italo-Tyrrhenian Province (Mediterr…

2012

The Juniperus phoenicea subsp. turbinata formations of the Italo-Tyrrhenian biogeographical province (Mediterranean Region), are analyzed on the basis of literature data and unpublished relevés. The floristic-synecological characterization of the identified phytocoenoses, confirmed by multivariate analysis on a synoptic basis, has allowed their breakdown in four different alliances of the order Pistacio lentisci-Rhamnetalia alaterni: 1) Periplocion angustifoliae, with the association Periploco angustifoliae-Juniperetum turbinatae; 2) Juniperion turbinatae, with the associations Junipero turbinatae-Quercetum calliprini, Rusco aculeati-Quercetum calliprini, Phillyreo angustifoliae-Juniperetum…
