NEW GUIDED BONE REGENERATION PROCEDURE USING LEUKOCYTE AND PLATELET RICH FIBRIN (L PRF) IN ORAL SURGERY

2021

Non-transfusional hemocomponents are autogenous products used in several surgical fields obtained by the centrifugation of a blood sample from a patient and able to promote hard and soft tissue regeneration, local haemostasis, and the acceleration of wound healing. The aim of this PhD thesis was the validation of an innovative protocol for the Guided Bone Regeneration (GBR) technique using second-generation autologous platelet concentrates, Leukocytes and Platelet-rich Fibrin (L-PRF), in post-extraction sockets of patients in need of dental avulsions and successive implant prosthetic rehabilitation, evaluating its ability to prevent alveolar bone resorption and promote bone regeneration.

Confluens-sinuum-Obstruktion durch Langerhanszell-Histiozytose

1996

Die Langerhanszell-Histiozytose, bis vor wenigen Jahren als Histiozytose X bezeichnet, umfast 3 verschiedene Syndrome, namlich das eosinophile Granulom, die Hand-Schuller-Christian-Krankheit sowie die Abt-Letterer-Siwe-Krankheit, und gehort zu den seltenen Erkrankungen des Kindesalters. Wir berichten uber einen 10 jahrigen Jungen, der mit einer Schwellung am Hinterkopf und beginnender Hirndrucksymptomatik zur stationaren Aufnahme kam. Klinik, konventionelle radiologische Diagnostik und Computertomographie liesen differentialdiagnostisch ein eosinophiles Granulom als wahrscheinlich erscheinen. MRT und MRT-Angiographie zeigten jedoch die akute Bedrohung des Patienten durch das intrakraniale W…

Úlcera eosinofílica lingual: un reto diagnóstico de patogénesis controvertida

2013

ResumenLa úlcera eosinofílica, también conocida como granuloma ulcerativo traumático con eosinofilia estromal, es una infrecuente y benigna lesión ulcerativa de la mucosa oral que presenta una evolución persistente, planteando a menudo diferentes diagnósticos clínicos diferenciales. Su diagnóstico se establece solo a partir del estudio histopatológico, si bien su morfología presenta a menudo características que pueden sugerir al patólogo la existencia de un proceso linfoproliferativo, traduciendo una patogénesis lesional controvertida todavía no bien aclarada.Comunicamos una observación clínico-patológica de úlcera eosinofílica afectando a una mujer de 76 años de edad. La lesión, de 2,5cm d…

Could halophilic archaea improve the traditional salted anchovies (Engraulis encrasicholus L) manufacture?

2008

Although initial interest on extremely halophilic archaea turned to their involvement in the spoilage of salted meat and fish products, studies on the occurrence of such microorganisms in food ecosystems have rarely been performed. During salted anchovies production, a traditional process used by Mediterranean fishermen to obtain a tender product with a specific pleasant aroma and taste, extremely halophilic archaea belonging to the Halobacteriaceae family are often isolated. In order to elucidate the influence of halobacteria in salting and curing of this product, an experimental manufacturing was performed according to a traditional procedure. Salt to be employed was artificially inoculat…

Fluorine Scan of Inhibitors of the Cysteine Protease Human Cathepsin L: Dipolar and Quadrupolar Effects in the π-Stacking of Fluorinated Phenyl Rings…

2016

The π-stacking of fluorinated benzene rings on protein backbone amide groups was investigated, using a dual approach comprising enzyme-ligand binding studies complemented by high-level quantum chemical calculations. In the experimental study, the phenyl substituent of triazine nitrile inhibitors of human cathepsin L (hCatL), which stacks onto the peptide amide bond Gly67-Gly68 at the entrance of the S3 pocket, was systematically fluorinated, and differences in inhibitory potency were measured in a fluorimetric assay. Binding affinity is influenced by lipophilicity (clog P), the dipole and quadrupole moments of the fluorinated rings, but also by additional interactions of the introduced fluo…

Synthesis of fluorinated oxadiazoles with gelation and oxygen storage ability

2012

A new family of fluorinated low molecular weight (LMW) gelators has been synthesized through SNAr substitution of 5-polyfluoroaryl-3-perfluoroheptyl-1,2,4-oxadiazoles with glycine ester. The obtained compounds give thermal and pH-sensitive hydrogels or thermo-reversible organogels in DMSO. Oxygen solubility studies showed the ability to maintain high oxygen levels in solution and in gel blend with plate counter agar (PCA).

Effect of fat nature and aroma compound hydrophobicity on flavor release from complex food emulsions.

2004

Complex food emulsions containing either hydrogenated palm kernel oil (vegetable fat) or anhydrous milk fat (animal fat) were flavored by using different aroma compounds. The fats differed by their fatty acid and triacylglycerol compositions and by their melting behavior, while the aroma compounds (ethyl butanoate, ethyl hexanoate, methyl hexanoate, mesifurane, linalool, diacetyl, cis-3-hexen-1-ol, and gamma-octalactone) differed by their hydrophobicity. Application of differential scanning calorimetry to fat samples in bulk and emulsified forms indicated differences in the ratio of solid-to-liquid between temperatures ranging from 10 to 35 degrees C. Solid-phase microextraction coupled wit…
