Italian pediatric respiratory society recommendations on pediatric pulmonary function testing during COVID-19 pandemic

2020

The coronavirus disease 2019 (COVID-19) is a public health emergency of international concern caused by a newly discovered coronavirus (severe acute respiratory syndrome coronavirus 2, SARS-CoV-2). Person-toperson transmission of SARS-CoV-2 occurs primarily through close contact with an infected person, mainly occurring via respiratory droplets and after touching contaminated objects. Accordingly, pulmonary function testing (PFT) could be considered at high-risk for viral transmission due to the potential for coughing and droplet formation during PFT procedures. The most likely surfaces for possible contamination by this route are mouthpieces, proximal valves, and tubing. Also, both technic…

Metagenomics reveals our incomplete knowledge of global diversity

2008

Metagenomic sequencing obtains huge amounts of sequences from environmental and clinical samples, thus providing a glimpse of the global prokaryotic diversity of both species and genes in these sources. The current trend in metagenomic analysis follows the so-called gene-centric approach, focused on describing the environments by the study of the functional roles of the proteins encoded in the sequenced genes. In this way, it is clear that metagenomic analysis relies heavily on the accurate knowledge of the universe of proteins stored in the databases. Nevertheless, it is known that some biases exist in the composition of databases (which are rich in sequences from common, cultivable and ea…

Kollokationen in Leserbriefen der Wochenzeitschrift Die Zeit

2020

Im Rahmen der Phraseologieforschung haben Kollokationen traditionell nur wenig Beachtung gefunden. Im Gegensatz zu Idiomen sind sie in der Regel semantisch transparent und bereiten daher Fremdsprachenlernern selten rezeptive Schwierigkeiten. Bei der Textproduktion muss jedoch die Problematik der Kollokationen beachtet werden. Aus diesem Grund halten wir Kollokationen für einen wichtigen Bereich der Phraseologie. Im vorliegenden Beitrag wird die Aufmerksamkeit auf die syntaktische Struktur, den Gebrauch und die Funktion von Kollokationen in 243 Leserbriefen der Zeitschrift Die Zeit gerichtet. Nach Heranziehung zweier Kollokationswörterbücher sowie einiger anderer Quellen konnten 278 Kollokat…

Correlations between the Presence of Hurthle Cells and Cytomorphological Features of Fine-Needle Aspiration Biopsy in Thyroid Nodules

2019

INTRODUCTION: The presence of Hürthle cells (HC) in fine needle thyroid biopsy (FNAB) is a real concern for a cytologist and also for an endocrinologist. We aimed to demonstrate if the presence of HC is associated with specific cytological features in FNAB results. MATERIAL AND METHODS: This retrospective study analyzed 89 patients diagnosed with thyroid nodules, with FNAB; were two groups of patients: the study group A (HC+) (22 patients) with HC and control group B (HC-) (67 patients) with no HC; for both groups we analyzed the presence of 9 cytomorphologic features: overall cellularity, background colloid, lymphocyte infiltration, chronic inflammation, large nucleoli, small nucleoli, syn…

Radiofrequency ablation for thyroid nodules: which indications? The first Italian opinion statement

2015

Nodular thyroid disease is a very common finding in clinical practice, discovered by ultrasound (US) in about 50 % of the general population, with higher prevalence in women and in the elderly [1–4]. Whereas therapeutic flowchart is quite established and shared for malignant lesions, multiple options are now available for patients presenting with benign thyroid nodules, ranging from simple clinical and US follow-up to thyroid surgery. The majority of thyroid nodules, benign by fine-needle aspiration, are asymptomatic, stable, or slow-growing over time and require no treatment. Nevertheless, large thyroid nodules may become responsible for pressure symptoms, resulting in neck discomfort, cos…

GyDB mobilomics: LTR retroelements and integrase-related transposons of the pea aphid Acyrthosiphon pisum genome

2011

[EN] The Gypsy Database concerning Mobile Genetic Elements (release 2.0) is a wiki-style project devoted to the phylogenetic classification of LTR retroelements and their viral and host gene relatives characterized from distinct organisms. Furthermore, GyDB 2.0 is concerned with studying mobile elements within genomes. Therefore, an in-progress repository was created for databases with annotations of mobile genetic elements from particular genomes. This repository is called Mobilomics and the first uploaded database contains 549 LTR retroelements and related transposases which have been annotated from the genome of the Pea aphid Acyrthosiphon pisum. Mobilomics is accessible from the GyDB 2.…

Comment on "Epidemiological Survey on Porcine Cysticercosis in Nay Pyi Taw Area, Myanmar".

2015

We have read with interest the paper by Khaing et al. [1], in which first data on Taenia solium cysticercosis in pigs from Myanmar are published. The authors found a porcine cysticercosis prevalence of 23.67% in slaughtered pigs, which, as they mention, indicates the presence of human taeniasis and also the risk of acquiring human cysticercosis and, therefore, neurocysticercosis. The high porcine cysticercosis prevalence detected by the authors means, obviously, that there has to be a high prevalence of human T. solium taeniasis among the inhabitants of Myanmar leading to a high presence of infective eggs in the environment. However, as far as we know, the presence of T. solium taeniasis, a…
