Pentoxifylline and tocopherol for the treatment of osteoradionecrosis of the jaws. A systematic review

2023

Osteoradionecrosis of the jaws (ORNJ) is a severe and challenging complication of head and neck radiation therapy. Despite its aggressiveness and controversy respect to its efficacy, surgical intervention remains the main treatment modality. Nevertheless, due to advances in the understanding of ORNJ physiopathology, new treatment alternatives such as the combination of pentoxifylline with tocopherol (PENTO) have emerged. The aim of this systematic review was to assess the reported efficacy of PENTO for the treatment of ORNJ.  Studies were search using Pubmed, The Cochrane Library, Scopus, and Web of Science data bases following the PRISMA guidelines. Inclusion criteria were cohort, case ser…

El arte de la medalla conmemorativa. Luis XIV de Francia como paradigma de retórica metálica

2023

La clasificación de las artes en niveles de excelencia desde la Ilustración ha tenido para la historia del arte una serie de consecuencias que, junto con la etiqueta que supuso hablar desde entonces de las Bellas Artes frente a otras menores, relegó a secundarias toda una serie de manifestaciones artísticas que si bien podían haber sido menos ricas en cuanto a fuste monumental se refiere, solo hacia la contemporaneidad estaban sufriendo una significada caída en picado en cuanto a su producción y mecenazgo. La medallística -de la que excluimos para este estudio la medalla devocional, militar, gitones e insignias- aún siendo todavía un instrumento conmemorativo en uso durante la Edad Contempo…

RAÍCES MITOLÓGICAS EN LA ICONOGRAFÍA DE LA BELLA DURMIENTE EL CASO DE LA BELLA DURMIENTE DE WALT DISNEY

2020

Sleeping Beauty is a story we can all tell. A cursed princess who pricks herself and falls into a deep sleep until her prince wakes her up. But, like all stories, she has evolved into this form. If we trace its origins, the first time it was put down on paper was in the 13th century. Later, in the 14th century, three more versions were added. In the 17th century Giambattista Basile popularized it, but in that same century Perrault adapted it to his own way and in the 19th century the Brothers Grimm simplified it.             Through all these forms there remains an essence, a common narrative, some characteristic elements that allow us to identify this story as the same one. And in them we …

Plasma membrane glycoproteins covalently bound to silica beads as a model for molecular studies of cell-cell interactions in culture.

1987

Abstract In previous studies, we have shown that plasma membrane glycoproteins are of major importance in the density-dependent regulation of growth of normal diploid fibroblasts. Due to the hydrophobic portions of these molecules, functional studies in cell culture are often diffucult to perform and to interpret. Specially, the addition of these molecules in soluble form to cell culture, after depletion of detergents needed for their solubilization, leads to aggregation and internalization. Therefore, we developed a method for the covalent immobilization of the solubilized plasma membrane proteins to derivatized silica beads for further investigations on the molecular nature of the active …

The Concept of Lexicon Devoted to Silesian Culinary Art

2019

As far as Silesia is concerned the language and cuisine constitute fundamental and distinguishing factors of the Silesian ethnic group, they are the determinants of cultural identity and the symbol of cultural identification. The concept of perceiving the culinary art from two perspectives, cultural and linguistic one, was born taking the above into account. Culinary art, as a component of culture understood in a broad manner, serves as a significant element of the language system as well. It plays a crucial culture-forming role in human life and it has certain position in the semantic structure of language which is adequate to its rank. The lexicon of Silesian cuisine, which is being curre…

In vowel discrimination, commonly found discrimination patterns are directional asymmetries where discrimination is faster (or easier) if differing vowels are presented in a certain sequence compared to the reversed sequence. Different models of speech sound processing try to account for these asymmetries based on either phonetic or phonological properties. In this study, we tested and compared two of those often-discussed models, namely the Featurally Underspecified Lexicon (FUL) model (Lahiri and Reetz, 2002) and the Natural Referent Vowel (NRV) framework (Polka and Bohn, 2011). While most studies presented isolated vowels, we investigated a large stimulus set of German vowels in a more n…

Functional Near Infrared Spectroscopy System Validation for Simultaneous EEG-FNIRS Measurements

2019

Functional near-infrared spectroscopy (fNIRS) applied to brain monitoring has been gaining increasing relevance in the last years due to its not invasive nature and the capability to work in combination with other well–known techniques such as the EEG. The possible use cases span from neural-rehabilitation to early diagnosis of some neural diseases. In this work a wireline FPGA–based fNIRS system, that use SiPM sensors and dual-wavelength LED sources, has been designed and validated to work with a commercial EEG machine without reciprocal interference.

Mesoporous Silica-Based Materials with Bactericidal Properties

2019

[EN] Bacterial infections are the main cause of chronic infections and even mortality. In fact, due to extensive use of antibiotics and, then, emergence of antibiotic resistance, treatment of such infections by conventional antibiotics has become a major concern worldwide. One of the promising strategies to treat infection diseases is the use of nanomaterials. Among them, mesoporous silica materials (MSMs) have attracted burgeoning attention due to high surface area, tunable pore/particle size, and easy surface functionalization. This review discusses how one can exploit capacities of MSMs to design and fabricate multifunctional/controllable drug delivery systems (DDSs) to combat bacterial …

Fungal Necrotizing Scleritis After Intravitreal Injection Therapy

2020

PURPOSE To report a case of infectious necrotizing scleritis secondary to Aspergillus terreus after intravitreal injection therapy. METHODS This is a case report with literature review. RESULTS A 98-year-old woman receiving intravitreal aflibercept injections for neovascular age-related macular degeneration in the left eye presented with severe pain, redness, and purulent discharge at the injection site. She was initially treated with topical fortified antibiotics, and clinical improvement was achieved, although microbial cultures showed negative results. Two months later, she presented with severe ocular pain and was diagnosed with anterior necrotizing scleritis. Scleral scrapings were col…
