A customizable digital holographic microscope.

We propose a compact, portable, and low-cost holographic microscope designed for the characterization of micrometric particles suspended in a liquid. This system is built around a commercial optical microscope by substituting its illumination source (a light-emitting diode) with a collimated laser beam. Similarly, a quartz flow cell replaces the microscope glass slide using a 3D-printed custom mount.

Perceptions and Expectations of Youth Regarding the Respect for Their Rights in the Hospital.

Information obtained from children themselves regarding the characteristics of the ideal hospital that ensure well-being during a hospital stay is scarce. Here, we report the opinions, perceptions, and expectations of 700 children and adolescents about their experiences, assessed through a mixed-method research approach with age-appropriate questionnaires, three open-ended questions, and an analysis of optional pictorial and textual narratives. Most children indicated that, while they acknowledged the expertise of hospital staff, they also noted several shortcomings, e.

Patterns of progression on first line osimertinib in patients with EGFR mutation-positive advanced non-small cell lung cancer (NSCLC): A Swiss cohort study.

Aim: Osimertinib is a third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) approved for patients with EGFR mutated non-small cell lung cancer as first-line treatment. However, treatment resistance inevitably emerges and may present as oligo-progressive disease (OPD) or systemic progressive disease (SPD). The incidence of OPD on first-line osimertinib is unknown.

Solving classification tasks by a receptron based on nonlinear optical speckle fields.

Among several approaches to tackle the problem of energy consumption in modern computing systems, two solutions are currently investigated: one consists of artificial neural networks (ANNs) based on photonic technologies, the other is a different paradigm compared to ANNs and it is based on random networks of non-linear nanoscale junctions resulting from the assembling of nanoparticles or nanowires as substrates for neuromorphic computing. These networks show the presence of emergent complexity and collective phenomena in analogy with biological neural networks characterized by self-organization, redundancy, and non-linearity. Starting from this background, we propose and formalize a generalization of the perceptron model to describe a classification device based on a network of interacting units where the input weights are non-linearly dependent.

Clinical variability of neurofibromatosis 1: A modifying role of cooccurring PTPN11 variants and atypical brain MRI findings.

Neurofibromatosis 1 (NF1) is a disorder characterized by variable expressivity caused by loss-of-function variants in NF1, encoding neurofibromin, a protein negatively controlling RAS signaling. We evaluated whether concurrent variation in proteins functionally linked to neurofibromin contribute to the variable expressivity of NF1. Parallel sequencing of a RASopathy gene panel in 138 individuals with molecularly confirmed clinical diagnosis of NF1 identified missense variants in PTPN11, encoding SHP2, a positive regulator of RAS signaling, in four subjects from three unrelated families.

Hypertransaminasemia in patients with Kawasaki disease (KD) is reported to be transient. Here, we describe a child with an atypically protracted course of liver tests abnormalities and review the inherent literature. The patient was hospitalized at age 7-months for isolated hypertransaminasemia detected during a classical KD diagnosed 3 months before, and persistent since then.

Clinical heterogeneity of Kabuki syndrome in a cohort of Italian patients and review of the literature.

Kabuki syndrome (KS) is a well-recognized disorder characterized by postnatal growth deficiency, dysmorphic facial features, skeletal anomalies, and intellectual disability. The syndrome is caused by KMT2D gene mutations or less frequently KDM6A gene mutations or deletions. We report a systematic evaluation of KS patients from Campania region of Italy; data were also compared with literature ones.

TSPO PET upregulation predicts epileptic phenotype at disease onset independently from chronic TSPO expression in a rat model of temporal lobe epilepsy.

Neuroinflammation is a key component of epileptogenesis, the process leading to acquired epilepsy. In recent years, with the development of non-invasive in vivo positron emission tomography (PET) imaging of translocator protein 18 kDa (TSPO), a marker of neuroinflammation, it has become possible to perform longitudinal studies to characterize neuroinflammation at different disease stages in animal models of epileptogenesis. This study aimed to utilize the prognostic capability of TSPO PET imaging at disease onset (2 weeks post-SE) to categorize epileptic rats with distinct seizure burden based on TSPO levels at disease onset and investigate their association to TSPO expression at the chronic epilepsy stage.

A systematic literature review of liver involvement in MADD was performed as well.

Dense-code free space transmission by local demultiplexing optical states of a composed vortex.

We describe an innovative data transmission scheme exploiting optical vortices to multiplex and demultiplex independent data channels in a standard asynchronous laser link. We report extensive results of the proof of concept of the method, successfully used to transmit two parallel ASCII strings, demultiplexed and decoded in the far field of the radiation beam. A phase locked two arms interferometer is proved to be effective even accessing a small portion of the beam only.

A ZFYVE19 gene mutation associated with neonatal cholestasis and cilia dysfunction: case report with a novel pathogenic variant.

Background: ZFYVE19 (Zinc Finger FYVE-Type Containing 19) mutations have most recently been associated to a novel type of high gamma-glutamyl transpeptidase (GGT), non-syndromic, neonatal-onset intrahepatic chronic cholestasis possibly associated to cilia dysfunction. Herein, we report a new case with further studies of whole exome sequencing (WES) and immunofluorescence in primary cilia of her cultured fibroblasts which confirm the observation.

Results: A now 5-year-old girl born to clinically healthy consanguineous Moroccan parents was assessed at 59 days of life due to severe cholestatic jaundice with increased serum bile acids and GGT, and preserved hepatocellular synthetic function.

Live European School of Oncology e-Sessions (e-ESO).

The European School of Oncology (ESO) embarked on an online educational project, starting with live sessions in 2008 (e-ESO). Our scholars and young oncologists identified the need to be offered independent high-level online education with contributions from experts around the world, free of charge and available at any moment. We report on various types of e-sessions, such as grand-rounds, highlights, debates, clinical cases and other sessions.

First-line treatment of NRAS-mutated metastatic melanoma with a MEK inhibitor.

Until recently, standard treatment for advanced melanoma comprised basically dacarbazine and interleukin-2, leading to low response rates and significant toxicity. These days, new treatments such as immunotherapy (anti-CTLA4 and anti-PD1 antibodies) and targeted therapy with BRAF/MEK-inhibitor combinations for patients harboring a BRAF mutation are available. In BRAF wild-type patients harboring an NRAS mutation, not fit for immunotherapy treatment options are still dismal.
