Postural Adjustments and Kinematic Index Finger Features in Frail Older Adults under Different Equilibrium Constraints

2021

Background: Anticipatory postural adjustments (APAs) are significantly affected by age and may represent restrictions on functional independence. Previous studies in young adults have already highlighted that changing postural stability (i.e., seated vs. upright posture) affects the motor planning and APAs. In frail older adults (FOAs), the effect of these different conditions of postural stability have not yet been established, and the present study aimed to disentangle this issue. Methods: Participants executed an arm-pointing task to reach a diode immediately after it turned on, under different conditions of stability (seated with and without foot support and in an upright posture). A ki…

Finger injuries caused by power-operated windows of motor vehicles: an experimental cadaver study.

2011

The aim of this experimental cadaver study was to investigate which kinds of lesions could occur in jam events between the glass and seal entry of power-operated motor vehicle side door windows at two different closing forces. Ten hands of fresh cadaver specimens were used. Three different hand positions chosen to simulate real events in which a finger is jammed between the glass and seal entry of the window of a current motor vehicle were examined. The index, middle, ring, and little finger of each hand were separately jammed both at the proximal and distal interphalangeal joint at closing forces of 300 and 500 N with a constant window glass closing speed of 10 cm/s. Macroscopically visibl…

Temperature sensation: the "3-bowls experiment" revisited.

1990

The "3-bowls experiment", usually attributed to E. H. Weber*, will be remembered by many from their first lab course in human physiology. The left and right hands are immersed for several minutes in bowls containing water at 10 and 40°C, respectively. When both hands are then placed in a third bowl of water at 27 °C, the left hand feels distinctly warm and the right hand distinctly cool. Until now nobody has been able to reconcile this apparent unreliability of the sense of temperature with the observation that humans regularly make judgements of the temperatures of objects; for example, mothers seldom use a thermometer to check the temperature of a baby's milk, but rather hold the bottle a…

The “Jacobsen Flap” for the Treatment of Stage III–IV Dupuytren’s Disease at Little Finger: Our Review of 123 Cases

2011

For selective fasciectomy in patients with Dupuytren’s disease at Tubiana Stage I–II, midline longitudinal incisions with serial Z-plasties, Bruner zigzag incisions, and V-Y plasties over the palm and most severely affected fingers are accepted methods. Advantages of these approaches are good intraoperative visualization of the fibrous tissue, rapid dissection, minor tissue trauma, and usually the possibility of a tension-free wound closure (Brenner and Rayan 2003). In cases of Dupuytren’s disease at Stage III and IV, with severe digital flexion, inelastic overlying skin, and expected skin shortage after contracture release, these incisions may sometimes be useful, but in our experience, qu…

Osteoblastic osteogenic sarcoma in a 13-month-old girl.

1994

Summary Osteosarcoma is exceptional in early periods of life. Therefore osteosarcomas involvingthe bones of the hand are extremely rare. We present a case of an osteogenic sarcoma involving the second metacarpal bone of a 13-month-old girl who has been remaining free of disease, after treatment — radial amputation and chemotherapy pre- and post-operative-, for a period of 10 years in the follow-up.

The E3 Ubiquitin Ligase MID1 Catalyzes Ubiquitination and Cleavage of Fu

2014

Sonic Hedgehog (SHH)-GLI signalling plays an important role during embryogenesis and in tumorigenesis. The survival and growth of several types of cancer depend on autonomously activated SHH-GLI signalling. A protein complex containing the ubiquitin-ligase MID1 and protein phosphatase 2A (PP2A) regulates the nuclear localization and transcriptional activity of GLI3, a transcriptional effector molecule of SHH, in cancer cell lines with autonomously activated SHH signalling. However, the exact molecular mechanisms that mediate the interaction between MID1 and GLI3 remained unknown. Here, we show that MID1 catalyses the ubiquitination and proteasomal cleavage of the GLI3-regulator Fu. Our data…

Is It Possible to Produce Certified Hazelnut Plant Material in Sicily? Identification and Recovery of Nebrodi Genetic Resources, in vitro Establishme…

2021

Eight Sicilian cultivars of hazelnut (Corylus avellanaL.), namely-Curcia, Nociara Collica, Panottara Collica, Panottara Galati Grande, Parrinara, Panottara Baratta Piccola, Enzo, and Rossa Galvagno, registered into the Italian Cultivar Register of fruit tree species in 2017 were selected from Nebrodi area and establishedin vitro. The aim of the work was to carry out the sanitation of the cultivars and get virus-free plants from the most important viral pathogen threat, theapple mosaic virus. Virus-free plant material is essential for the production of certified plants from Sicilian hazelnut cultivars, complying the CE (cat. CAC) quality and the technical standards established in 2017 for vo…

The assessment of skeletal status in young patients with Turner syndrome by 2 densitometric techniques: Phalangeal quantitative ultrasound and dual e…

2018

Background. Studies using dual energy X-ray absorptiometry (DXA) demonstrate a reduction in bone mineral density (BMD) in children and adolescents with Turner syndrome (TS). However, these studies do not take into account changes in bone size, which influence BMD in the case of short-statured patients. Phalangeal quantitative ultrasound (phQUS) measurements have shown an ability to reveal changes due to skeletal growth, aging, and bone and mineral disorders. There is limited data on bone mineral status in girls with TS assessed by 2 different techniques, i.e., DXA and phQUS. Objectives. The aim of this study was to investigate the potential negative impact of TS on bone status and to assess…
