Peripheral ossifying fibromas are benign mesenchymal lesions that usually arise in the anterior maxilla of young female patients. Histologically they consist of spindle cell proliferation with focal mineralisation. We reviewed 48 specimens from 41 patients and recorded the clinical data, sex, and age of the patients, site and size of the lesions, treatment, and postoperative outcome. Histologically the presence of mature, woven bone, cementum, and calcifications were evaluated and evaluated immunohistochemically. ...

The ATP6V1C1 gene encodes the C1 subunit of the vacuolar-ATPase (V-ATPase) proton pump. This gene is over-expressed in oral squamous cell carcinoma (OSCC) as determined by real-time quantitative polymerase chain reaction. The aim of our study was to perform an immunohistochemical study of the distribution of the C1 subunit in normal epithelium of the oral cavity and in OSCC. We analyzed the expression of the C1 subunit in eight OSCC samples and two normal oral mucosa samples using polyclonal V-ATPase ...

The present study concerns Atlantic mackerel (Scomber scombrus) traded as a chilled product. The study was aimed to investigate the effect of including a mixture of organic acids (citric, ascorbic, and lactic) in the icing medium employed during the fish chilled storage. To this end and according to preliminary trials results, an aqueous solution including 0.050% (w/v) of each acid was employed as icing medium; its effect on the microbial activity development in mackerel muscle was monitored for up ...

Immunohistochemical detection of mediators of inflammation, such as P-Selectin, has been proposed to assess vitality of wounds. Forty-five incised cutaneous wounds (24 vital, 14 post-mortem, seven with induced autolysis/putrefaction) were immunostained with antibodies against P-Selectin and CD31. The percentage of stained lumina for P-Selectin out of the total of CD31 positive vessels (P-S/CD31 index) was calculated at both edges of every specimen. In vital samples, the P-S/CD31 index ranged from ...

Oral squamous cell carcinomas represent more than 90% of all head and neck cancers, and comprise about 4% of all malignancies in western countries. Tumor cell mobility related to increasing intracellular pH results in impaired proliferation and metastasis, suggesting an important role of pH regulation in solid cancer tumorigenesis. The mechanism of physiological pH regulation has been shown to be activated in several solid tumors through constitutive activation of the ATPase complex. How cells regulate ...

As, Hg, and Se are the most volatile elements in the flue gas from a coal-fired power plant. Significant amounts of these elements cause an undesired direct gaseous emission, which leads to a serious environmental health risk. The main focus of this study is to evaluate the possibility of simultaneous sampling of these volatile elements using an accurate official method for Hg (the most volatile element). A study of As, Hg, and Se emissions from a 1400 MW coal-fired power plant equipped with electrostatic ...

Immunohistochemical detection of molecules involved in inflammatory reaction can be useful for the diagnosis of vitality in skin wounds. We studied the expression of fibronectin (FN) and tenascin (TN) in 58 human skin wounds (48 vital and 10 postmortem). The age of vital injuries ranged from 3 min to 8 h and postmortem specimens were collected after a postinfliction interval of 15-180 min. One hundred thirty-seven formalin-fixed paraffin-embedded sections (mean: 2.3 sections per case) were stained with ...

The expression of antifungal genes from Trichoderma harzianum, mainly chitinases, has been used to confer plant resistance to fungal diseases. However, the biotechnological potential of glucanase genes from Trichoderma has been scarcely assessed. In this research, transgenic strawberry plants expressing the β-1,3-glucanase gene bgn13.1 from T. harzianum, under the control of the CaMV35S promoter, have been generated.

It is established that the mechanical properties of hydrogels control the fate of (stem) cells. However, despite its importance, a one-to-one correspondence between gels' stiffness and cell behaviour is still missing from literature. In this work, the viscoelastic properties of Poly(ethylene-glycol) (PEG)-based hydrogels - broadly used in 3D cell cultures and whose mechanical properties can be tuned to resemble those of different biological tissues - are investigated by means of rheological measurements ...

In this work, CaTiO3 powders doped with Mg2+ ions and CaTiO3 powders co-doped with Mg2+ and Eu3+ ions were prepared by the polymeric precursor method (PPM). These powders were characterized by different characterization techniques to study the influence of Mg2+ doping as well as Mg2+ and Eu3+ co-doping in structural and optical properties of CaTiO3 perovskite-type structure. The Rietveld refinement and Micro-Raman analyses suggested the substitution Mg2+ and Eu3+ ions in the A-site of CaTiO3 perovskite. ...

Periodic first-principles calculations based on density functional theory at the B3LYP level has been carried out to investigate the photoluminescence (PL) emission of BaZrO(3) assembled nanoparticles at room temperature. The defect created in the nanocrystals and their resultant electronic features lead to a diversification of electronic recombination within the BaZrO(3) band gap. Its optical phenomena are discussed in the light of photoluminescence emission at the green-yellow region around 570 ...

A quantitative classification of soil texture is proposed based on an entropic index that can be easily computed from knowledge of the fractional contents of soil textural classes. It is first shown that the index formula supplies a number that agrees with the entropy dimension when the corresponding soil particle-size distribution (PSD) displays self-similar fractal features. In the absence of self-similarity, the index is further shown to retain information-theoretic content so that it becomes ...

The Rietveld method was applied to perform quantitative analysis of the coexisting phases. The ratio of tetragonal/rhombohedral phases increased with calcination temperature. For the composition where Zr/Ti = 53/47, the tetragonal quantity varied from 25% to 35% for temperatures ranging from 600° to 800°C. For the powder with Zr/Ti = 57/43, only the rhombohedral phase was ...
