Abnormal red cell structure and function in neuroacanthocytosis.

Background: Panthothenate kinase-associated neurodegeneration (PKAN) belongs to a group of hereditary neurodegenerative disorders known as neuroacanthocytosis (NA). This genetically heterogeneous group of diseases is characterized by degeneration of neurons in the basal ganglia and by the presence of deformed red blood cells with thorny protrusions, acanthocytes, in the circulation.

Objective: The goal of our study is to elucidate the molecular mechanisms underlying this aberrant red cell morphology and the corresponding functional consequences.

Performance of a novel sieving matrix of poly(vinyl alcohol)/acrylamide copolymer in electrophoretic separations of high molecular weight proteins from red cell membrane.

The analysis of high molecular weight (HMW) proteins from complex mixtures is still a challenge in proteomics. This work introduces a novel hydrogel obtained by the copolymerization of an allyl-PVA derivative with acrylamide and bisacrylamide and applies this matrix to the electrophoretic separation of HMW proteins. By inducing gelation of polyacrylamide in the presence of variable amounts of allyl-PVA, it is possible to control and vary the average gel porosity.

Functional consequences of sphingomyelinase-induced changes in erythrocyte membrane structure.

Inflammation enhances the secretion of sphingomyelinases (SMases). SMases catalyze the hydrolysis of sphingomyelin into phosphocholine and ceramide. In erythrocytes, ceramide formation leads to exposure of the removal signal phosphatidylserine (PS), creating a potential link between SMase activity and anemia of inflammation.

Robot-assisted practice of gait and stair climbing in nonambulatory stroke patients.

A novel gait robot enabled nonambulatory patients the repetitive practice of gait and stair climbing. Thirty nonambulatory patients with subacute stroke were allocated to two groups. During 60 min sessions every workday for 4 weeks, the experimental group received 30 min of robot training and 30 min of physiotherapy and the control group received 60 min of physiotherapy.

Computational identification of phospho-tyrosine sub-networks related to acanthocyte generation in neuroacanthocytosis.

Acanthocytes, abnormal thorny red blood cells (RBC), are one of the biological hallmarks of neuroacanthocytosis syndromes (NA), a group of rare hereditary neurodegenerative disorders. Since RBCs are easily accessible, the study of acanthocytes in NA may provide insights into potential mechanisms of neurodegeneration. Previous studies have shown that changes in RBC membrane protein phosphorylation state affect RBC membrane mechanical stability and morphology.

Adaptive locomotor training on an end-effector gait robot: evaluation of the ground reaction forces in different training conditions.

The main goal of robotic gait rehabilitation is the restoration of independent gait. To achieve this goal different and specific patterns have to be practiced intensively in order to stimulate the learning process of the central nervous system. The gait robot G-EO Systems was designed to allow the repetitive practice of floor walking, stair climbing and stair descending.

Erythrocyte membrane changes of chorea-acanthocytosis are the result of altered Lyn kinase activity.

Acanthocytic RBCs are a peculiar diagnostic feature of chorea-acanthocytosis (ChAc), a rare autosomal recessive neurodegenerative disorder. Although recent years have witnessed some progress in the molecular characterization of ChAc, the mechanism(s) responsible for generation of acanthocytes in ChAc is largely unknown. As the membrane protein composition of ChAc RBCs is similar to that of normal RBCs, we evaluated the tyrosine (Tyr)-phosphorylation profile of RBCs using comparative proteomics.

Combined transcranial direct current stimulation and robot-assisted arm training in subacute stroke patients: an exploratory, randomized multicenter trial.

Background: No rehabilitation intervention has effectively improved functional use of the arm and hand in patients with severe upper limb paresis after stroke. Pilot studies suggest the potential for transcranial direct current stimulation and bilateral robotic training to enhance gains.

Objective: In a double-blind, randomized trial the combination of these interventions was tested.

Combined transcranial direct current stimulation and robot-assisted gait training in patients with chronic stroke: a preliminary comparison.

Objective: To evaluate whether robot-assisted gait training combined with transcranial direct current stimulation is more effective than robot-assisted gait training alone or conventional walking rehabilitation for improving walking ability in stroke patients.

Design: Pilot randomized clinical trial.

Setting: Rehabilitation unit of a university hospital.

Innovative gait robot for the repetitive practice of floor walking and stair climbing up and down in stroke patients.

Background: Stair climbing up and down is an essential part of everyday's mobility. To enable wheelchair-dependent patients the repetitive practice of this task, a novel gait robot, G-EO-Systems (EO, Lat: I walk), based on the end-effector principle, has been designed. The trajectories of the foot plates are freely programmable enabling not only the practice of simulated floor walking but also stair climbing up and down.

Microplate spectrophotometry for high-throughput screening of cytotoxic molecules.

Objectives: High-throughput chemical and biochemical technologies are now exploited by modern pharmacology and toxicology to synthesize a multitude of new molecules with bioactive potential, or to isolate them from living matter. Testing molecules in cell systems on a large scale, however, is a rate-limiting step in drug discovery or in toxicity assessment. In this study, we developed a low-cost high-throughput method for first-level screening of cytotoxic molecules.

Transfer of scientific concepts to clinical practice: recent robot-assisted training studies.

Restoration of motor function is a priority of post-stroke rehabilitation, the aim being to facilitate the patient's reintegration into society. Innovative technologies for neurological rehabilitation must be easy to use and offer patients real benefits, and the treatments they provide must be efficacious and efficient. All these aspects must be carefully evaluated in their development.

Effects of wheat germ agglutinin on human gastrointestinal epithelium: insights from an experimental model of immune/epithelial cell interaction.

Wheat germ agglutinin (WGA) is a plant protein that binds specifically to sugars expressed, among many others, by human gastrointestinal epithelial and immune cells. WGA is a toxic compound and an anti-nutritional factor, but recent works have shown that it may have potential as an anti-tumor drug and as a carrier for oral drugs. To quantitate the toxicity threshold for WGA on normal epithelial cells we previously investigated the effects of the lectin on differentiated Caco2 cells, and showed that in the micromolar range of concentrations WGA could alter the integrity of the epithelium layer and increase its permeability to both mannitol and dextran.

A new electromechanical trainer for sensorimotor rehabilitation of paralysed fingers: a case series in chronic and acute stroke patients.

Background: The functional outcome after stroke is improved by more intensive or sustained therapy. When the affected hand has no functional movement, therapy is mainly passive movements. A novel device for repeating controlled passive movements of paralysed fingers has been developed, which will allow therapists to concentrate on more complicated tasks.

A quantitative study of growth variability of tumour cell clones in vitro.

Objectives: In this study, we quantify growth variability of tumour cell clones from a human leukaemia cell line.

Materials And Methods: We have used microplate spectrophotometry to measure growth kinetics of hundreds of individual cell clones from the Molt3 cell line. Growth rate of each clonal population has been estimated by fitting experimental data with the logistic equation.

Automatic segmentation of chromosomes in Q-band images.

Karyotype analysis is a widespread procedure in cytogenetics to assess the possible presence of genetics defects. The procedure is lengthy and repetitive, so that an automatic analysis would greatly help the cytogeneticist routine work. Still, automatic segmentation and full disentangling of chromosomes are open issues.

Children of heroin addicts.

Fourteen Black male, opiate addicts, their wives, and their children were studied intensively using psychiatric interviews and psychological tests. Their 32 children were compared to 37 pediatric clinic children. The children raised in a home where father is an opiate addict function cognitively less well than their father, and the teenagers show earlier and stronger antisocial trends than pediatric clinic peers.

Who are the "committed"?

A record review of patients who were committed by the court during the course of a hospitalization at an acute urban facility was carried out. Court-committed patients represented 4% of total patients admitted during a 2-year period. Black patients and patients over the age of 70 were more likely to reach the stage of a court hearing and be committed.
