Temperature requirements for seed germination of Pereskia aculeata and Pereskia grandifolia.

Pereskia aculeata and Pereskia grandifolia have been studied widely due to their high nutritional and therapeutic values. However, little is known about the biological requirements of their seeds for the various germination factors. Thus, this experiment aimed to evaluate the thermal effects on the germination of these species at the temperatures of 24°C, 27°C, 30°C, 33°C and 36°C.

Treatment of intrabony pockets with Emdogain: results at 36 months.

This study reports the results obtained 36 months after treating deep periodontal defects with amelogenins. Results at 12 months have already been published. Sixteen of 21 patients completed the 3-year recall program.

Tilt-table test during transcranial Doppler monitoring in Parkinson's disease.

Cardiovascular autonomic dysfunction can occur in Parkinson's disease (PD) and intracranial vascular modifications following orthostatism may be relevant to diagnostic and therapeutic decision-making. We performed transcranial Doppler monitoring of right middle cerebral artery (MCA) at rest and during passive 70 degrees tilt in 19 patients with idiopathic PD and in 19 age-matched normal controls. Brachial arterial blood pressure (systolic, diastolic and mean), cardiac frequency (CF), respiratory frequency and mean velocity (MV) of the MCA were recorded after 10 min of rest in supine position, and each minute during 9 min of tilting and 5 min of restored clinostatic position.

Abnormalities of sensorimotor integration in focal dystonia: a transcranial magnetic stimulation study.

It has been postulated that sensorimotor integration is abnormal in dystonia. We investigated changes in motor cortical excitability induced by peripheral stimulation in patients with focal hand dystonia (12 patients with hand cramps) and with cervical dystonia (nine with spasmodic torticollis) compared with 16 age-matched normal controls. Motor evoked potentials (MEP) to focal (figure-of-eight coil) transcranial magnetic stimulation of the hand area were recorded from the right abductor pollicis brevis (APB), first dorsal interosseus (FDI), flexor carpi radialis and extensor carpi radialis muscles.

Use of Emdogain in the treatment of deep intrabony defects: 12-month clinical results. Histologic and radiographic evaluation.

The objective of this study was to evaluate the application of an enamel matrix derivative (Emdogain) in deep periodontal pocket therapy. Twenty-one patients presenting intrabony and interproximal defects that could be treated with guided tissue regeneration were selected. The intrabony defects were divided into deep (< 9 mm) and very deep (> or = 9 mm) defects.
