Technical design report for the upgrade of the ALICE inner tracking system
2014
ALICE (A Large Ion Collider Experiment) is studying the physics of strongly interacting matter, and in particular the properties of the Quark–Gluon Plasma (QGP), using proton–proton, proton–nucleus and nucleus–nucleus collisions at the CERN LHC (Large Hadron Collider). The ALICE Collaboration is preparing a major upgrade of the experimental apparatus, planned for installation in the second long LHC shutdown in the years 2018–2019. A key element of the ALICE upgrade is the construction of a new, ultra-light, high- resolution Inner Tracking System (ITS) based on monolithic CMOS pixel detectors. The primary focus of the ITS upgrade is on improving the performance for detection of heavy-flavour…
Association of recurrent mutations in BRCA1, BRCA2, RAD51C, PALB2, and CHEK2 with the risk of borderline ovarian tumor.
2021
Abstract Background There are several genes associated with ovarian cancer risk. Molecular changes in borderline ovarian tumor (BOT) indicate linkage of this disease to type I ovarian tumors (low-grade ovarian carcinomas). This study determined the prevalence and association of mutations in BRCA1, BRCA2, PALB2, RAD51C, and CHEK2 with the risk of BOTs. Methods The study group consisted of 102 patients with histologically confirmed BOT and 1743 healthy controls. In addition, 167 cases with ovarian cancer G1 were analyzed. The analyses included genotyping of 21 founder and recurrent mutations localized in 5 genes (BRCA1, BRCA2, PALB2, RAD51C, and CHEK2). The risk for developing BOT and low-gra…
Alpha-adrenergic drugs in retrograde ejaculation.
1974
6 men with complete or partial loss of ejaculation as a result of retroperitoneal lymphadenectomy (performed because of testicular tumor) were treated with an intravenous injection of 60 mg synephrine. Synephrine stimulates adrenergic alpha-receptors. Only 1 man with sustained retrograde ejaculation improved following treatment showing antegrade ejaculation. This temporary restoration of fertility was thought to be due to an increase in bladder neck tone and prevention of backflow of semen into the bladder as a result of stimulation of adrenergic alpha-receptors.
Long Term Results of Bladder Exstrophy
1999
After primary bladder closure or urinary diversion, other factors apart from the reconstruction gain importance for individuals with the exstrophy-epispadias complex: social integration and, after reaching puberty, sexuality and fertility.
Ejaculation Disorders in Male Patients with Cancer: A Systematic Review and Meta-Analysis of Prevalence
2021
PURPOSE: Ejaculatory dysfunction (EjD) and erectile dysfunction after cancer treatment are clinically important complications, but their exact prevalence by various kinds of cancer site and type of treatment is unknown. The aim of this systematic review and meta-analysis was to examine the available evidence and provide pooled estimates for prevalence of EjD and erectile dysfunction in relation to all cancer sites and identify characteristics associated with EjD in cancer patients. MATERIALS AND METHODS: We performed a systematic review and meta-analysis of cross-sectional and case-control studies. We searched 4 electronic databases (Medline®, CINAHL, PsychInfo and Embase®) until July 22, 2…
When, why, and how to perform wire-based antegrade dissection and reentry technique
2022
Antegrade dissection and reentry (ADR) refers to an attempt to cross a coronary chronic total occlusion (CTO) lesion through wire and/or equipment passage in the subintimal space followed by reentry to the distal true lumen. From the original subintimal tracking and reentry (STAR) technique description by Colombo in 2005, refinement of the technique, improved characteristics of the microcatheters and wires, and better understanding of subadventitial vessel trauma have led to higher success rates, lower complications rates, and improved long-term outcomes. In this chapter, we discuss the technique, its outcomes, and limitations.
Predictores y efectos de la repetición de curso
2018
About a third of Spanish students will have repeated at least one school year by the time they reach 16. It is claimed that alternative policies top grade repetition should seek to provide individualised treatment and ensure early intervention. In Spain, while there is empirical evidence in support of the benefits of the former, there is little for the latter. Here, we fill this gap by combining data from two international assessments. We identify the profile of students who a) are at greatest risk of grade retention and b) are most negatively affected by the policy. Our results confirm the importance of early intervention and the need to rethink grade repetition as a one-size-fits-all poli…
Scour on alluvial bed downstream of grade-control structures
2004
This paper describes an approach for predicting local scour downstream of grade control structures. The developed analysis applies the incomplete self-similarity (ISS) theory for deducing some physically based dimensionless groups controlling the geometrical pattern of the scour profile. The scour measurements available in the literature in conjunction with numerous unpublished data allow a multiregressive calibration of the ISS relationships. The experimental sample includes different bed grain-size distributions and scales of the erosive phenomenon. The results prove that the ratio between the upstream water head and the weir height is able to explain the measurements of scour depth carri…
Small-diameter titanium grade IV and titanium-zirconium implants in edentulous mandibles: five-year results from a double-blind, randomized controlle…
2015
BACKGROUND The aim of this study was to compare the 5-year survival and success rates of 3.3 mm dental implants either made from titanium-zirconium (TiZr) alloy or from Grade IV titanium (Ti Grade IV) in mandibular implant-based removable overdentures. METHODS The core study had a follow-up period of 36 months and was designed as a randomized, controlled, double-blind, split-mouth multicenter clinical trial. Patients with edentulous mandibles received two Straumann Bone Level implants (diameter 3.3 mm, SLActive®), one of TiZr (test) and one of Ti Grade IV (control), in the interforaminal region. This follow-up study recruited patients from the core study and evaluated the plaque and sulcus …
Integration of PCL and PLA in a monolithic porous scaffold for interface tissue engineering.
2016
A novel bi-layered multiphasic scaffold (BLS) have been fabricated for the first time by combining melt mixing, compression molding and particulate leaching. One layer has been composed by polylactic acid (PLA) presenting pore size in the range of 90-110µm while the other layer has been made of polycaprolactone (PCL) with pores ranging from 5 to 40µm. The different chemo-physical properties of the two biopolymers combined with the tunable pore architecture permitted to realize monolithic functionally graded scaffolds engineered to be potentially used for interface tissues regenerations. BLS have been characterized from a morphological and a mechanical point of view. In particular, mechanica…
