1. Novos métodos para estimativa da idade óssea baseados no processamento de imagens radiográficas da mão / New methods to bone age estimation based on hand radiographic image processing
Bone age (or skeletal maturity) assessment using a radiograph of the left hand is a common procedure in pediatric radiology. The methods most widely used for bone age determination presents high complexity degree for estimation, usually performed by radiologist and this task is extremely complex and time-consuming producing results with high charge of person

2. Bone quantity and quality assessed by ultrasound of phalanges in black and white children s six to eleven years old / Quantidade e qualidade ossea avaliada pela ultrassonografia de falanges em crianças brancas e negras de seis a onze anos de idade de diferentes
Thesis Structuring: The present study opted for the "Scandinavian Model" which is called the "Alternative Model" in the Post-Graduation Program in Child and Adolescent Health from the Medical Sciences College of University of Campinas (UNICAMP). Therefore, the thesis was compounded by introduction, objective, chapters (I and II) and general conclusion. The i

3. Identification of CANT1 Mutations in Desbuquois Dysplasia
Desbuquois dysplasia is a severe condition characterized by short stature, joint laxity, scoliosis, and advanced carpal ossification with a delta phalanx. Studying nine Desbuquois families, we identified seven distinct mutations in the Calcium-Activated Nucleotidase 1 gene (CANT1), which encodes a soluble UDP-preferring nucleotidase belonging to the apyrase

4. Control of motor units in human flexor digitorum profundus under different proprioceptive conditions.
1. Changing the posture of the human fingers can functionally 'disengage' the deep finger flexor muscle from its normal action on the terminal phalanx of the fourth (or third) finger. This enables the activity of the muscle to be studied both with and without its normal proprioceptive inputs. 2. Spike trains of long duration from pairs of concurrently active

5. Evidence for a contribution of the motor cortex to the long-latency stretch reflex of the human thumb.
1. In normal subjects, transcranial magnetic stimulation of the hand region of the motor cortex evokes motor responses only in contralateral hand muscles at a latency of about 19-24 ms. In contrast, stimulation of the motor cortex of three mirror movement subjects evoked, nearly simultaneously, motor responses in hand muscles on both sides of the body at lat

6. Limited independent flexion of the thumb and fingers in human subjects.
1. We investigated whether human subjects can activate selectively flexor pollicis longus (FPL) and digital portions of flexor digitorum profundus (FDP). These muscles were selected because they are the only flexors of the distal phalanges. 2. Electromyographic activity (EMG) was recorded with intramuscular electrodes from one digital component of the deep f

7. Evidence from the use of vibration that the human long-latency stretch reflex depends upon spindle secondary afferents.
The electromyographic activity of flexor pollicis longus has been recorded in normal human subjects on moving the tip of the thumb with the proximal phalanx clamped. Ramp and hold displacements (stretches) were compared with high-frequency sinusoidal movement (vibration). The subject exerted a constant flexor force between stimuli and made no voluntary respo
