Quantitative Stereological Estimations of Structural Patterns of the Glandular Tree in Benign Hyperplasia of Prostate  [PDF]
Luis Santamaría, Ildefonso Ingelmo, Fernando Teba, Almudena Coloma, Laura Martínez
Open Journal of Pathology (OJPathology) , 2016, DOI: 10.4236/ojpathology.2016.63015
Abstract: Background: Benign prostate hyperplasia (BPH) is the most common benign disease of human prostate. Currently BPH is associated with unregulated proliferation of connective tissue and glandular epithelium within the prostatic transition zone, and it has been described as relevant characteristic of BPH—the increase of the total number of cells, and not only an increase in cell size. To date, there are few studies on the quantitative morphology of glandular tree of BPH compared with normal prostate. The scarce investigations about this particular suggest that the glandular tree branches and expands as the hyperplastic transformation occurs in the prostate. Methods: To verify if this gland expansion and branching was similar to that occurs in the normal prostate, this study deals with the estimation of several stereological parameters as: labeling index for the proliferating cell nuclear antigen to quantify the rate of proliferation of prostate epithelium, average thickness of glandular epithelium, fraction of the volume occupied by the epithelium relative to the total prostate volume, connectivity density of prostate glands, to quantify the branching of prostate glands, and the average volume and the volume-weighted mean glandular volume of prostate acini to assess the mean size of the prostate acini and its variability. Results: All these estimates have been performed in prostate specific antigen immunostained sections from prostates of young men (controls) and in adenomectomy specimens from the adenofibromiomatous variety of BPH. Conclusion: We conclude that the epithelial proliferation is not the only factor intervening in the development of BPH. In addition, a more prolonged survival of epithelial population, together with some degree of hypertrophy of acini expressed by the increase of volume fraction and thickness of acinar epithelium, is relevant in order to the growth and expansion of the BPH glandular tree that shows more abundant and heterogeneous acinar sprouts than in normal prostate.

Abstract: purposes: to describe the visual manifestations of brain neoplasms, and to analyze the effect of tumor control on these. methods: this is a descriptive retrospective study, which includes patients under 14 years of age, suffering from different brain neoplasms in our hospital between 1996 and 2005 inclusive. results: in the group of patients with low visual acuity, 44% had organic amblyopias. in 28% of cases, the amblyopia was secondary to the strabismus/nystagmus produced by the developing tumor. corrective treatment was successful in some cases of partial or total organic amblyopia. ophthalmologic evaluation (including perimetry and fundoscopy) enabled detection of 3 tumor relapses. conclusions: visual analysis (visual acuity, perimetry, fundoscopy) should be an essential component of assessment during brain neoplasm treatment and follow-up. corrective treatment is sometimes successful in organic amblyopias.

Abstract: Objetivos: Describir las manifestaciones visuales en neoplasias neuropediátricas, relacionarlas con la localización tumoral y analizar su relevancia en el seguimiento de la enfermedad. Material y métodos: Estudio descriptivo retrospectivo que incluye pacientes menores de 14 a os con neoplasias cerebrales de cualquier estirpe, registradas en nuestro centro desde 1996 hasta el 2005. Resultados: En un 44% de los pacientes con descenso en la agudeza visual, la ambliopía fue catalogada como orgánica. En el 28% de los casos, la ambliopía era secundaria al estrabismo/nistagmus producido por el tumor. El tratamiento corrector resultó efectivo en varios casos de ambliopía parcial y totalmente orgánica. Tres recidivas tumorales fueron detectadas gracias a la exploración de fondo de ojo y campimetría, antes de que las pruebas de imagen fueran concluyentes. Conclusión: El examen oftalmológico (agudeza visual, campimetría, funduscopia) es una pieza clave en el seguimiento de la patología tumoral cerebral. Las ambliopías orgánicas parciales/totales son susceptibles de tratamiento corrector.

Abstract: Background: The collapse of the alveolar ridge in an edentulous area in patients who will undergo oral rehabilitation impedes the harmonic relationship between pontic and ridge. To correct this type of defect there are several surgical techniques that aim to achieve soft tissue augmentation, allowing the conformation of an ideal profile with the use of a pontic. The aim was to demonstrate how the technique of tissue modification in an area with a class b defect of Allen allows the correction of aesthetics in the anterior dental sector. Case presentation: A 41-year-old Mexican woman. Extra and intraoral examination was performed, the dental treatment included connective tissue graft and rehabilitation with Zirconia. Conclusion: Surgery of residual alveolar ridge augmentation with connective tissue graft gives the patient favorable aesthetic results in the anterior area when it will be rehabilitated.

Abstract: Nowadays, we are facing a renaissance of mitochondria in cancer biology. However, our knowledge of the basic cell biology and on the timing and mechanisms that control the biosynthesis of mitochondrial constituents during progression through the cell cycle of mammalian cells remain largely unknown. Herein, we document the in vivo changes on mitochondrial morphology and dynamics that accompany cellular mitosis, and illustrate the following key points of the biogenesis of mitochondria during progression of liver cells through the cycle: (i) the replication of nuclear and mitochondrial genomes is synchronized during cellular proliferation, (ii) the accretion of OXPHOS proteins is asynchronously regulated during proliferation being the synthesis of β-F1-ATPase and Hsp60 carried out also at G2/M and, (iii) the biosynthesis of cardiolipin is achieved during the S phase, although full development of the mitochondrial membrane potential (ΔΨm) is attained at G2/M. Furthermore, we demonstrate using reporter constructs that the mechanism regulating the accretion of β-F1-ATPase during cellular proliferation is controlled at the level of mRNA translation by the 3′UTR of the transcript. The 3′UTR-driven synthesis of the protein at G2/M is essential for conferring to the daughter cells the original phenotype of the parental cell. Our findings suggest that alterations on this process may promote deregulated β-F1-ATPase expression in human cancer.

Abstract: an automatic online inspection system, based on machine vision, has been developed to improve the easyopen can end repair coating quality control in canmaking industry and canneries. the machine vision algorithm estimates the average repair coating quality on each end using a fuzzy system. in this work the algorithm and the fuzzy system building via neuro-fuzzy modeling is presented. the inspection system checks the total production, classifies the ends in agreement with an expert human inspector, supplies interpretability to the operators in order to find out the failure causes and reduce the mean time needed to solve failures, and allows to modify the minimum can end repair coating quality. the algorithm allows the inspection of the whole production process and can be extended to other can end formats.
