Hands-feet wireless devices: Test-retest reliability and discriminant validity of motor measures in Parkinson's disease telemonitoring

2022

Background Telemonitoring, a branch of telemedicine, involves the use of technological tools to remotely detect clinical data and evaluate patients. Telemonitoring of patients with Parkinson's disease (PD) should be performed using reliable and discriminant motor measures. Furthermore, the method of data collection and transmission, and the type of subjects suitable for telemonitoring must be well defined. Objective To analyze differences in patients with PD and healthy controls (HC) with the wearable inertial device SensHands-SensFeet (SH-SF), adopting a standardized acquisition mode, to verify if motor measures provided by SH-SF have a high discriminating capacity and high intraclass corr…

Neural Correlates of Age-Related Changes in Precise Grip Force Regulation: A Combined EEG-fNIRS Study

2020

Motor control is associated with suppression of oscillatory activity in alpha (8–12 Hz) and beta (12–30 Hz) ranges and elevation of oxygenated hemoglobin levels in motor-cortical areas. Aging leads to changes in oscillatory and hemodynamic brain activity and impairments in motor control. However, the relationship between age-related changes in motor control and brain activity is not yet fully understood. Therefore, this study aimed to investigate age-related and task-complexity-related changes in grip force control and the underlying oscillatory and hemodynamic activity. Sixteen younger [age (mean ± SD) = 25.4 ± 1.9, 20–30 years] and 16 older (age = 56.7 ± 4.7, 50–70 years) healthy men were…

A genomic reappraisal of symbiotic function in the aphid/Buchnera symbiosis: reduced transporter sets and variable membrane organisations.

2011

International audience; Buchnera aphidicola is an obligate symbiotic bacterium that sustains the physiology of aphids by complementing their exclusive phloem sap diet. In this study, we reappraised the transport function of different Buchnera strains, from the aphids Acyrthosiphon pisum, Schizaphis graminum, Baizongia pistaciae and Cinara cedri, using the re-annotation of their transmembrane proteins coupled with an exploration of their metabolic networks. Although metabolic analyses revealed high interdependencies between the host and the bacteria, we demonstrate here that transport in Buchnera is assured by low transporter diversity, when compared to free-living bacteria, being mostly bas…

MULTIFUNCTION REACTOR

2022

Described herein is a reactor (1) includes: a first reaction volume (V1), a second reaction volume (V2), wherein: the first reaction volume (V1) is in fluid communication with an inlet port for an oxidizer agent (OX_IN), an inlet port for at least one first reactant (R1_IN) and an outlet port for at least one reaction product (P1_OUT), said second reaction volume (V2) is in fluid communication with an inlet port for at least one second reactant (R2_IN), an outlet port for at least one second reaction product (P2_OUT) and is furthermore in thermal exchange relationship with said first reaction volume (V1), wherein, during operation, in said first reaction volume (V1) an oxidation reaction oc…

MR2817222 Ursescu, Corneliu, A mean value inequality for multifunctions. Bull. Math. Soc. Sci. Math. Roumanie (N.S.) 54(102) (2011), no. 2, 193–200

2011

The paper is devoted to extend some mean value inequalities from the function setting to the multifunction one. Let (M,d) be a metric space, let F be a multifunctions defined on D \subset R and taking values in the family of nonempty subsets of M, and let g: D\rightarrow R be a strictly increasing function. The author proves the following inequality: \frac{\delta(F(b),F(a))}{g(b)-g(a)} \leq \sup_{s\in [a,b)\cap D} \sup_{S\in F(s)} \sup_{t\in (s,b)\cap D} \frac{\delta(F(t),S)}{g(t)-g(s)}, where a and b are two points of D with a<b and, if Q and P are nonempty subsets of M, then \delta(Q,P)=\sup_{p\in P} \inf_{q\in Q}d(q,p). An application of the previous inequality to the Dini derivatives of…

IL RUOLO DELLE AREE AGRICOLE NELLA PROGETTAZIONE TERRITORIALE. Gli aspetti sociali come forma di rivitalizzazione del territorio.

2014

La tesi indaga il tema della multifunzionalità applicata all’agricoltura come strumento per riattivare territori abbandonati, degradati, a rischio di uso improprio o di nuova edificazione. L’agricoltura ha sempre avuto un rapporto fondamentale con l’Uomo e con gli insediamenti. Il rapporto tra centri abitati e aree agricole è stato un rapporto di unione e di contrapposizione. Nel passaggio da agricoltura di sussistenza a quella di tipo intensivo e specializzato sono stati coinvolti gli spazi, le tecniche, gli strumenti, le opere legate all’attività agricola e, infine, il rapporto con il territorio. L’agricoltura, benché produca beni di prima necessità, nei decenni scorsi è stata considerata…

Rational Chemical Multifunctionalization of Graphene Interface Enhances Targeted Cancer Therapy

2020

The synthesis of a drug delivery platform based on graphene was achieved through a step‐by‐step strategy of selective amine deprotection and functionalization. The multifunctional graphene platform, functionalized with indocyanine green, folic acid, and doxorubicin showed an enhanced anticancer activity. The remarkable targeting capacity for cancer cells in combination with the synergistic effect of drug release and photothermal properties prove the great advantage of a combined chemo‐ and phototherapy based on graphene against cancer, opening the doors to future therapeutic applications of this type of material.

Marked elevation of transaminases and pancreatic enzymes in severe malnourished male with eating disorder

2013

We report a case of a 45 year old Caucasian malnourished male with an history of eating disorder who developed severe liver and pancreatic damage and multiorgan disfunction. At admission to our department, his body mass index (BMI) was 11.1. Biochemical evaluation showed elevated serum levels of transaminases (AST= 2291 U/L, ALT= 1792 U/L), amylase (3620 U/L), lipase (4102 U/L), CPK= 1370 U/L, LDH= 2082 U/L. No other cause of acute liver and pancreatic damage was evidenced. Haematological disorders (anemia, thrombocytopenia, leukopenia) found on admission seem related to bone marrow hypoplasia and to gelatinous marrow transformation described in severe state of malnutrition. Although a mode…
