The spectrum of androgen excess disorders.

2006

A better understanding of the different phenotypes and of their endocrine and metabolic characteristics permits investigators to distinguish three main androgen excess disorders: classic polycystic ovary syndrome (PCOS), mild ovulatory PCOS, and idiopathic hyperandrogenism. These androgenic phenotypes differ more for the severity of the endocrine and metabolic alteration than for the etiopathogenetic mechanisms. The appearance of a particular androgenic phenotype is determined by a sum of genetic and environmental factors, but mostly by body weight.

Ventilation volumes with different self-inflating bags with reference to the ERC guidelines for airway management: comparison of two compression tech…

2000

The 1998 ERC-guidelines for airway-management recommend an tidal volume of 400-600 ml for adults undergoing CPR. As commercially available self-inflating bags were designed to meet former recommendations (800-1200 ml) we investigated how to meet the latest recommendations with these bags. We combined the head of a training manikin (Laerdal Medical) and a standard lung (VTTL; Michigan Instrument), adjusted to a physiological compliance and resistance. Volume was measured with a Wright spirometer (BOC). Seven self-inflating bags were investigated. Tests were carried out by ten people (five female and five male) for 5 min each using two different techniques. Technique 1: standard ventilation w…

Transcranial magnetic resonance-guided focused ultrasound surgery at 1.5T: a technical note.

2019

Magnetic resonance-guided focused ultrasound is one of the emerging non-invasive technologies offering both image guidance and thermal monitoring. In recent years transcranial application of this technology is starting to impact heavily the neuroscience field. We present here the imaging protocol and the technological methods successfully used with a transcranial magnetic resonance-guided focused ultrasound system certified for clinical treatments of functional neurological disorders, integrated for the first time with a 1.5T magnetic resonance scanner. Compared to the body radiofrequency coil (the one commonly used with transcranial magnetic resonance-guided focused ultrasound system integ…

Ultrasound-guided percutaneous treatment of a calcific acromioclavicular joint

2020

RATIONALE Calcific tendinopathy is one of the most frequent causes of nontraumatic shoulder pain. However, intra-articular calcifications appear to be an infrequent condition. We herein report a rare case study of an intra-articular calcification of the acromioclavicular joint. PATIENT CONCERNS A 46-year-old man presented with an acute pain in the anterior superior region of the left shoulder which also radiated to the left cervical region. The man during the physical evaluation also presented severe functional limitation of the shoulder movements in all planes of motion. DIAGNOSES The diagnosis was carried out through a radiographic and an echotomographic examination, highlighting the intr…

Caring for Infants and Children Following Alternative Dietary Patterns

2017

The number of people that refrain from eating meat has apparently increased. This is due to a variety of factors other than economic constraints or religious concerns, which have long been reasons for such dietetic conduct. Several reasons for adopting diets excluding meat include improved health, concerns regarding animal welfare, the use of antibiotics and hormones in livestock, and the excessive exploitation of environmental resource. Consequently, the number of children whose parents decide to follow alternative diets, such as vegetarian, vegan, macrobiotic, or fruitarian, is also growing. Clinical research regarding adults adopting such diets has expanded, and their nutritional impact …

Special considerations for studies of extracellular vesicles from parasitic helminths: A community-led roadmap to increase rigour and reproducibility.

2023

Over the last decade, research interest in defining how extracellular vesicles (EVs) shape cross-species communication has grown rapidly. Parasitic helminths, worm species found in the phyla Nematoda and Platyhelminthes, are well-recognised manipulators of host immune function and physiology. Emerging evidence supports a role for helminth-derived EVs in these processes and highlights EVs as an important participant in cross-phylum communication. While the mammalian EV field is guided by a community-agreed framework for studying EVs derived from model organisms or cell systems [e.g., Minimal Information for Studies of Extracellular Vesicles (MISEV)], the helminth community requires a supplem…

Coded excitation speeds up the detection of the fundamental flexural guided wave in coated tubes

2016

The fundamental flexural guided wave (FFGW) permits ultrasonic assessment of the wall thickness of solid waveguides, such as tubes or, e.g., long cortical bones. Recently, an optical non-contact method was proposed for ultrasound excitation and detection with the aim of facilitating the FFGW reception by suppressing the interfering modes from the soft coating. This technique suffers from low SNR and requires iterative physical scanning across the source-receiver distance for 2D-FFT analysis. This means that SNR improvement achieved by temporal averaging becomes time-consuming (several minutes) which reduces the applicability of the technique, especially in time-critical applications such as…

Evaluation of Subgrade Resilient Modulus Predictive Model for Use in Mechanistic-Empirical Pavement Design Guide

2006

The characterization of unbound materials in the mechanistic–empirical pavement design guide (MEPDG), also known as the 2002 design guide, is reviewed, and this characterization is applied to Minnesota subgrades. The main emphasis is on the collection of k1-, k2-, and k3-parameters for Minnesota fine-grained soils and the procedure for the interpretation of the resilient modulus test to provide an input to the multilayer elastic theory (MLET) analysis (Level 2 input). This is an important aspect of adaptation of the MEPDG, because the guide recommends measurement of resilient moduli from laboratory testing, but the procedure does not specify how to interpret the test data to obtain an input …

Museums as disseminators of niche knowledge: Universality in accessibility for all

2019

Accessibility has faced several challenges within audiovisual translation Studies and gained great opportunities for its establishment as a methodologically and theoretically well-founded discipline. Initially conceived as a set of services and practices that provides access to audiovisual media content for persons with sensory impairment, today accessibility can be viewed as a concept involving more and more universality thanks to its contribution to the dissemination of audiovisual products on the topic of marginalisation. Against this theoretical backdrop, accessibility is scrutinised from the perspective of aesthetics of migration and minorities within the field of the visual arts in mu…
