Significance of immunohistochemistry biomarkers in prediction of malignant transformation of oral lichen planus
2022
Background: Oral lichen planus (OLP) is a chronic inflammatory disorder with increased risk for malignant transformation. Biomarker validation is a pivotal step in moving newly discovered biomarkers towards clinical implementation. We performed a systematic review of studies on biomarkers related to OLP, wherein biomarkers have been described in at least two independent studies. Our aim was to determine whether any of these biomark-ers might be promising in predicting the increased risk of malignant transformation of OLP. Material and Methods: We searched the following databases until August 2021: PUBMED, EMBASE, and Web of Science. Due to high heterogeneity, a qualitative rather than quant…
Janus Nanostructures from ABC/B Triblock Terpolymer Blends

Lamella-forming ABC triblock terpolymers are convenient building blocks for the synthesis of soft Janus nanoparticles (JNPs) by crosslinking the B domain that is &ldquo
A Controlled Trial of Two Acellular Vaccines and One Whole-Cell Vaccine against Pertussis
1996
Background Concern about both safety and efficacy has made the use of whole-cell pertussis vaccines controversial. In some European countries, including Italy, the rate of vaccination against pertussis is low. Methods We conducted a double-blind trial in Italy in which infants were randomly assigned to vaccination at two, four, and six months of age with an acellular pertussis vaccine together with diphtheria and tetanus toxoids (DTP); a DTP vaccine containing whole-cell pertussis (manufactured by Connaught Laboratories); or diphtheria and tetanus toxoids without pertussis (DT). The acellular DTP vaccine was either one containing filamentous hemagglutinin, pertactin, and pertussis toxin ina…
Oral lichenoid lesions related to contact with dental materials: A literature review
2007
Oral lichenoid lesions related to contact are defined as oral-cavity eruptions with an identifiable etiology, and are clinically and histologically similar to oral lichen planus. Within this group are found oral lichenoid lesions related to contact with dental materials (OLLC), the most common being those related to silver amalgam. Currently, it remains difficult to diagnose these lesions due to the clinical and histopathological similarity with oral lichen planus and other oral mucosa lesions of lichenoid characteristics. In the present paper, we carry out an updated review of the tests for, and the different characteristics of OLLC, which may aid the diagnosis. For this review, we made se…
Wild-type JAK2 secondary acute erythroleukemia developing after JAK2-V617F-mutated primary myelofibrosis.
2009
A 54-year-old female patient developed acute erythroleukemia after an 8-year course of primary myelofibrosis. The latter harbors the JAK2-V617F mutation and was treated with hydroxyurea and anagrelide. A bone marrow trephine biopsy disclosed 2 morphologically distinct areas of chronic primary myelofibrosis and acute erythroleukemia. Microdissection and a separate molecular pathological analysis was performed. Although the activating JAK2-V617F mutation was not maintained in blasts of acute erythroleukemia, it was detectable in the chronic phase of primary myelofibrosis, indicating that this mutation did not play a role in the leukemic transformation of erythroid cells.
A Poem for All Seasons: Alcuin’s “O vos, est aetas”
2017
There is no complete account of the transmission of Alcuin’s poems, which is apparently quite unpredictable if not random. The circulation of a number of short compositions, which accompany his treatises and his letters, and their circulation together, is so far uncharted. Particularly intriguing is the manuscript tradition of “O vos, est aetas,” a poem in seven distichs, in which young men are encouraged to learn rhetoric and to cultivate virtue. The poem generally occurs in connection with two prose works by Alcuin, the De dialectica (henceforth DD) and the Disputatio de rhetorica et virtutibus (henceforth DR). It may be copied either between the two treatises, before the prologue poem of…

Manuskrypt cechu krawców ze zbiorów Archiwum Państwowego w Opolu. Edycja krytyczna
2016
Anonimowy dokument z Archiwum Państwowego w Opolu włączony do zbioru „Cechy miasta Opola z lat 1470-1934, 123” o sygnaturze 80 jest zabytkiem, który ukazuje dzieje kultury materialnej z zakresu rzemiosła krawców i kostiumologii. Datowany jest on na około 1700 rok i z pewnością powstał na Śląsku. Podstawowym składnikiem opolskiego manuskryptu są wykroje w skali 23 prac krawieckich, głównie ubiorów noszonych przy końcu XVII wieku, ale wśród krawieckich szablonów znalazły się także wzory użytkowe, takie jak chorągiew kościelna, namiot wojskowy, strój na konia, dekoracja elewacji domu. Do unikatu wśród tego zbioru należy zaliczyć wykrój kontusza należącego do kompletu ubiorów polskich. Jego obe…
Structure and Shear Response of Janus Colloid–Polymer Mixtures in Solution
2020
We investigate the structure and rheological properties of dilute colloid-polymer mixtures at rest and under shear via molecular simulations that take into account hydrodynamic interactions. Mixtures of amphiphilic Janus colloids (JCs) and hydrophobic/amphiphilic polymers are considered for various solvent qualities and polymer concentrations. Free polymers, small polymer droplets, and hybrid aggregates coexist in mixtures with slightly hydrophobic homopolymers. As the solvent quality worsens, all polymers aggregate into small droplets, covered and stabilized by the JCs. In mixtures with amphiphilic polymers, we observe the coexistence of free polymers, purely polymeric micelles, and hybrid…
Enzyme pretreatment and negative pressure cavitation extraction of genistein and apigenin from the roots of pigeon pea [Cajanus cajan (L.) Millsp.] a…
2012
Abstract An enzyme pretreatment and negative-pressure cavitation extraction (E-NPCE) method was investigated for extraction genistein and apigenin from pigeon pea roots. The important parameters involved in E-NPCE process were optimized by single-factor experiments and then critical parameters were investigated by a 2 3 full factorial central composite design (CCD) to optimize extract conditions. Under optimal conditions, the yields of genistein and apigenin were 0.628 mg/g and 0.359 mg/g, which represented an increase of 44.70% and 53.05%, respectively, compared to standard NPCE. Furthermore, from DPPH scavenging activity test the extract of E-NPCE showed better antioxidant activity than t…
