MQDO theoretical study of the C1Π–X1Σ+ band system of HCl

2008

Abstract Oscillator strengths for P, Q and R rotational lines belonging to the (0, v ″ = 0, 1) and (1, v ″ = 0, 1) bands for the C 1 Π–X 1 Σ + system of HCl have been theoretically studied. The calculations have been performed by following the molecular quantum defect orbital methodology, which has earlier proved to yield accurate intensities for transitions involving Rydberg states in a variety of molecular species. The results appear to be in good accord with the available experimental values. Predictions of a number of unknown intensities have also been made. We expect that the present data might be of help in the interpretation of future experimental measurements.

A Particular Focus on the Prevalence of α- and β-Thalassemia in Western Sicilian Population from Trapani Province in the COVID-19 Era

2023

Thalassemia is a Mendelian inherited blood disease caused by α- and β-globin gene mutations, known as one of the major health problems of Mediterranean populations. Here, we examined the distribution of α- and β-globin gene defects in the Trapani province population. A total of 2,401 individuals from Trapani province were enrolled from January 2007 to December 2021, and routine methodologies were used for detecting the α- and β-globin genic variants. Appropriate analysis was also performed. Eight mutations in the α globin gene showed the highest frequency in the sample studied; three of these genetic variants represented the 94% of the total α-th…

TENSION FREE CYSTOCELE REPAIR. FOUR YEARS FOLLOW-UP

2003

Aims of study: Anterior vaginal wall descensus is one of the most frequent alteration in patients with pelvic defects. At least 50% of women that had delivered two or more times presented a certain degree of this pathologic alteration of the anatomy, even thought only 10-20% of the patients complained of associated pains. The use of synthetic biocompatible materials has become more common in gynecology surgery(1)-(3). Polypropylene mesh to be proposed as a mean of surgical correction of moderate severe cystocele (Cervigni 1998)(2) Methods: 97 patients aged 42-75, parity 1-5, body weight 45-90, menopause 41 pts. (61%).Irritative sintoms( nocturia, frequency, urgency, dysuria and urge inconti…

Influencia del error refractivo en la presión intraocular y en el espesor corneal central en una población de 6 a 17 años

2013

La presión intraocular (PIO) es la manifestación del contenido de humor acuoso en circulación en el ojo, siendo fundamental que la producción y drenaje estén dentro de un equilibrio adecuado para mantener en un estado óptimo de funcionamiento las estructuras oculares. Se considera que, dependiendo de cada persona, hay unos valores críticos, a partir de los cuales se produce una alteración microvascular, con un sufrimiento sobre todo de los tejidos nutridos en la zona del nervio óptico. Si persiste en el tiempo ocasiona una neuropatía óptica crónica y progresiva llamada glaucoma.

Valores de normalidad en parámetros oculares en niños caucásicos españoles

2015

<p align="justify"><em>Objetivo</em>: cuantificar los parámetros biométricos oculares, las propiedades biomecánicas corneales, la configuración anatómica del nervio óptico y la capa de fibras nerviosas de la retina (CFNR) en un grupo de niños, mediante técnicas no invasivas. <em>Material y métodos</em>: se realizó un estudio transversal, descriptivo y no aleatorio en 293 niños sanos caucásicos con edades entre 6 y 17 años. <em>Resultados</em>: se encontró una correlación estadísticamente significativa entre la longitud axial (LA) y la histéresis corneal (CH) (p < 0,001). También se encontró disminución de la CH con el incremento de la miopía …
