The phylogeny ofPapaver s. l. (Papaveraceae): Polyphyly or monophyly?

1997

An RFLP analysis of the chloroplast genetrnK of 32 species of the generaPapaver, Roemeria, Stylomecon, andMeconopsis leads to the following conclusions: (1) AsianMeconopsis consists of two distinct clades and is paraphyletic in relation toPapaver, Roemeria, Stylomecon, and the W EuropeanMeconopsis cambrica. (2) Sister group relationships ofRoemeria toPapaver sect.Argemonidium and ofStylomecon toPapaver californicum are well-supported. (3)Meconopsis cambrica is nested withinPapaver (incl.Roemeria andStylomecon). The consideration of morphology, geographical distribution and ecology leads to the conclusion thatM. cambrica is best regarded as a member ofMeconopsis, and thatPapaver arose polyph…

Htid-1, the human homolog of the Drosophila melanogaster l(2)tid tumor suppressor, defines a novel physiological role of APC.

2007

Htid-1, the human counterpart of the Drosophila tumor suppressor gene lethal(2)tumorous imaginal discs (l(2)tid) encodes three splice forms translated into three cytosolic - Tid50, Tid48 and Tid46 - and three mitochondrial - Tid43, Tid40 and Tid38 - proteins. Here we provide evidence for the association of the endogenous Tid50/Tid48 proteins with the adenomatous polyposis coli (APC) tumor suppressor in normal colon epithelium, colorectal cancer cells and mouse NIH3T3 fibroblasts. Using the Glutathione S-transferase binding assay we show that the N-terminal region including the Armadillo domain (ARM) of APC is sufficient to bind the Tid molecules. Using immunoprecipitation and confocal micro…

Unusual pattern of gastric and hepatic infiltration in an infant with acute monocytic leukemia

1995

A 10-month-old girl with acute monocytic leukemia is presented. Ultrasound of the abdomen on admission showed an unusual distribution of leukemia infiltrates in the stomach and liver. The leukemic infiltrates in the wall of the stomach presented as intraluminal polyps, while the leukemic infiltration of the liver was strictly confined to the portal vessels.

Dental Pulp Polyps Contain Stem Cells Comparable to the Normal Dental Pulps

2013

Objectives: Few studies investigated the isolation of stem cells from pathologically injured dental tissues. The aim of this study was to assess the possibility of isolation of stem cells from pulp polyps (chronic hyperplastic pulpitis), a pathological tissue produced in an inflammatory proliferative response within a tooth. Study design: Pulp polyp tissues were enzymatically digested and the harvested single cells were cultured. Cultured cells underwent differentiation to adipocytes and osteoblasts as well as flowcytometric analysis for markers such as: CD90, CD73, CD105, CD45, and CD14. In addition we tried to compare other characteristics (including colonigenic efficacy, population doubl…

Respiratory epithelial adenomatoid hamartoma: An unusual case report

2020

Respiratory epithelial adenomatoid hamartoma is a rare lesion of the nasal cavity whose etiology and pathogenesis are unknown and symptoms are unspecific. It can be isolated or associated with inflammatory process, first of all nasal polyposis. It’s considered a rare lesion because it’s poorly known and consequently correctly diagnosing is important to a right surgical treatment and follow-up. A 54-year-old man presented with a 10-year history of epistaxis, rhinorrhea and anosmia. Computed tomography showed soft tissue densities in all sinus cavities consistent with nasal polyposis and without bilateral widening of the olfactory cleft >10 mm and without bone erosion. Functional endoscopi…

Number 1Epithelial biology

2005

The oral mucous membrane has features similar to skin but also differs in several ways. This paper reviews the aspects of epithelial biology necessary for an understanding of the vesiculoerosive disorders.

Bilateral hairy polyp of the oropharynx.

1996

AbstractHairy polyp of the nasopharynx is an unusual but well-recognized entity, generally presenting as a single mass at birth or in the first year of life. We describe the clinico-pathological features of a previously unreported bilateral hairy polyp in an adult and briefly discuss the pathogenesis of this condition.

EFFECT OF ADDING SOLID AND MOLTEN CHOCOLATE ON THE POLYPHENOL CONTENT, CHEMICAL, TEXTURAL, MICROBIOLOGICAL AND SENSORY ASPECTS OF PECORINO SICILIANO …

In this project we used two specific food products, which are typically Sicilian, Pecorino Siciliano cheese and Modica chocolate, that have unique texture and taste. “Chocolate cheese” is produced with the aim of increasing the consumption of cheese especially among children, targeting the purpose of improving public health. In this research we investigated chocolate cheese including solid and molten chocolate in three levels of 5%, 10% and 15% at four ripening times (T0 = fresh, T1 = 2 weeks, T2 = 4 weeks and T3 = 6 weeks). The results showed that the addition of chocolate significantly (p ≤ 0.05) decreased the pH, ash and protein content of the Pecorino Siciliano cheese, whereas it had no…

Effects of polyphenols and lipids from Pennisetum glaucum grains on T-cell activation: modulation of Ca2+ and ERK1/ERK2 signaling

2015

International audience; BACKGROUND: Pearl millet (PM), i.e., Pennisetum glaucum, is widely grown in Africa and known for its anti-oxidant and anti-hyperlipidemic properties.METHODS: The P. glaucum grains were obtained from the region of Ouled Aïssa (South of Algeria). We assessed the effects of phenolic compounds and lipids, extracted from seeds of P. glaucum, on rat lymphocyte proliferation, activated by phorbol 12-myristate 13-acetate and ionomycin. In order to explore signaling pathway, triggered by these compounds, we assessed interleukin-2 (IL-2) mRNA expression and extracellular signal-regulated kinase-1/2 (ERK1/ERK2) phosphorylation. Finally, we determined increases in free intracell…

Glyphosate residues alter the microbiota of a perennial weed with a minimal indirect impact on plant performance

2021

Abstract Purpose In cold climates, glyphosate residues may linger in soils, with effects on plant–microbe interactions and, consequently, plant performance. Here, we explore the influence of glyphosate residues on the endophytic microbiota (bacteria and fungi) and performance of the perennial nitrogen-fixing weed Lupinus polyphyllus. Methods In a common garden, we grew plants from six populations of L. polyphyllus in glyphosate-treated or untreated control soils, with or without additional phosphorus. We sampled plant microbiota (leaves, roots, nodules) and assessed plant performance based on six traits: height, retrogression probability (i.e. shrinkage), biomass, root:shoot ratio, nodule n…
