Association of a single nucleotide polymorphism of RANK gene with blood pressure in Spanish women

2020

Abstract In addition to governing key functions in bone metabolism and the immune system, the RANK/RANKL/OPG system plays a role in the vascular system, particularly in vascular calcification and atherosclerosis. Given that these 2 phenotypes are considered a major cause of high blood pressure (BP), in this study we analyzed the association of SNPs in RANK and OPG genes with blood pressure. An observational study was conducted of 2 SNPs in the RANK gene (rs884205 and rs78326403) and 1 in the OPG gene (rs4876869) with systolic (SBP) and diastolic blood pressure (DBP) in a cohort of 695 women. Data analysis revealed a statistically significant association between the SNP rs884205 and BP press…

Stimulation with carbachol alters endomembrane distribution and plasma membrane expression of intracellular proteins in lacrimal acinar cells.

2000

The events that lead to Sjogren's autoimmune processes in the lacrimal gland remain poorly understood. The acinar cell's responses to acute cholinergic stimulation include release of secretory products across the apical plasma membrane (apm) and a number of processes related to traffic between endomembrane compartments and the basal-lateral plasma membranes (blm), such as recruitment of Na, K-ATPase, accelerated recycling, and accelerated transcytosis of secretory IgA. We tested the hypothesis that stimulation-induced acceleration of endomembrane traffic is accompanied by changes in compartmentation and increased blm expression of proteins that are normally sequestered in endomembrane compa…

Color Doppler imaging of the eye and orbit A synopsis of a 400 case experience

2009

Color Doppler imaging (CDI) is a recent advance in ultrasonography that allows simultaneous two-dimensional imaging of structure and blood flow. Doppler information is superimposed in color over a conventional gray-scale ultrasound image. Using this technique we have examined 400 eyes. The central retinal artery, posterior ciliary arteries, ophthalmic artery, the central retinal vein and the vortex veins could be located in all normal eyes. Using the color image as a guide, Doppler spectral analysis is used for quantitative assessment of blood flow velocity in these vessels. We also studied patients with intraocular tumors, arterial and venous retinal occlusions, orbital vascular anomalies …

The Principles of Quantum Theory

2013

This chapter develops the formal framework of quantum mechanics: the mathematical tools, generalization and abstraction of the notion of state, representation theory, and a first version of the postulates on which quantum theory rests.

Variations in acoustical beam properties of intracoronary Doppler catheters.

1993

The limitations of coronary angiography in assessing the functional significance of coronary obstructions is well known. While the critical variable of coronary blood flow cannot be readily measured, intraluminal Doppler sonography offers useful related functional information on blood flow velocity. In order to fully evaluate Doppler signals it is essential to have exact knowledge of the transducer transmission characteristics and of the ultrasound beam topology. In an experimental set-up, the transmitter-receiver characteristics of five commonly used Doppler catheters were investigated. In comparing the beam characteristics we found inhomogeneities in the lateral beam spread. At a penetrat…

The spectrum of risk factors for contrast induced nephropathy in patients undergoing coronary angiography or intervention

2014

Abstract Introduction Contrast induced nephropathy is an unfavorable acute event which can complicate the clinical course of patients undergoing coronary angiography. Clinical characteristics predisposing to its occurrence are still rather obscure. Methods We enrolled 591 patients (mean age 64.2 ± 10.98; 449 male and 142 female) who underwent emergency or elective Coronary angiography/Angioplastic in our Cardiologic Division between 10/2006 and 06/2008, paying attention to their Cardiovascular risk factors, dose and type of contrast medium, type and number of affected coronary arteries, pharmacological therapies, baseline renal function and extracoronary atherosclerosis. We performed a univ…

Occurrence and timing of complications following traumatic dental injuries: A retrospective study in a dental trauma department

2016

Background This study explores the pattern of complications occurrence resulting from traumatic dental injuries, the relation of this pattern to the number of years from the time of the injury to its first diagnosis, and other contributing characteristics such as root development and trauma characteristic. Material and Methods Patients’ data treated following dental trauma from 2002 to 2014 were classified and grouped according to age, gender, tooth type, injury type, diagnosis and the time that elapsed between the traumatic event and the diagnosis of complications (TIC). The distribution function of the quantitative parameters was determined with the Kolmogorov-Smirnov test. Fisher exact t…

Ethical reflections on Evidence Based Medicine

2013

BACKGROUND According to Potter’s point of view, medical ethics is the science of survival, a bridge between humanistic and scientific culture. The working out of judgements on right or wrong referred to the human being are studied by this science. Methodological quality is fundamental in clinical research, and several technical issues are of paramount importance in trying to answer to the final question “what is the true, the right thing?”. We know they are essential aspects as in medical ethics as in evidence based practice. AIM OF THE STUDY The aim of this paper is to talk about relationships and implications between ethical issues and Evidence Based Medicine (EBM). DISCUSSION EBM represe…

Evaluation of Podalic Support and Monitoring of Balance Control in Children with and without Dyslexia: A Pilot Study

2020

Background: The American Psychiatric Association has identified dyslexia as a neurobiological disorder. The aim of the study was to evaluate podalic support, balance control, and dyslexia’s effects on interpersonal relationships. Methods: Fifty-seven subjects were enrolled for this study. The subjects were divided into two groups. The experimental group was composed of children with diagnosis of dyslexia. The control group was composed of healthy subjects. Each subject underwent baropodometry and posturographic analysis. In addition, the Multidimensional Self-esteem Assessment test by Bracken was used for a precise measurement of self-esteem in both groups (TMA). Results: The static b…
