[Safety measures to prevent falls are introduced into the training course for people in charge of planning]. / La sicurezza anticaduta entra nel progetto Corso di formazione per addetti alla progettazione.

For to pursue and to stimulate adequate shapes of prevention of the risk of falls from the high, the ASL of the province of Bergamo has approved of the moderniization of the R.L.I. that it introduces the obligation of the predisposition of structural elements that they favor the successive one rests in work and 1 use of DPI. It has been activated, therefore, a Work group composed from doctors and technicians of the Sanitary Company and graduating of the Faculty of Building Engineering of Bergamo, with the obbiettivo of to create means of support for the been involved figures of system. Us one is prefixed this obbiettivo to useful the aim to predispose and to put into effect course to to answer to the needs formed you of the professional figures of system and not in matter of risk of fall from the high.

[Clinico-statistical study of 104 cases of deforming uropathies. Criteria for an early diagnosis]. / Studio clinico-statistico di 104 casi di uropatia malformativa - Criteri di diagnosi precoce.

The material of the present study consists of 104 children affected with urinary tract malformation, admitted to the Paediatric Division of the United Hospital of Bergamo between 1976 and 1981. In particular, for every child, the authors have recorded the symptoms at the time of hospitalization and former symptoms, the presence of concomitant bacteriuria and the type of germ, the coincidental occurrence of other malformative syndromes, the types of urinary tract malformation. The mean age at the time of the diagnosis was of 32,7 months (1 - 124). For 45 children the diagnosis has been placed within the first year of life, for 70 children within the first 3 years. The occurrence of absolutely asymptomatic urinary tract malformations and the absence of significant bacteriuria in several cases have been noticed. The authors underline some useful criteria for an early diagnosis: the accurate anamnesis, the careful consideration of the symptoms, the identification of the suspicious cases in which it is advisable to employ the uroradiological investigations without any delay. They also recommend a close cooperation between pediatrician, radiologist, nephrologist and paediatric surgeon. Finally the AA confirm the necessity of a better information to the territorial physicians about the problem of the urinary tract malformations.

Restoration by T4 ligase of DNA sequences sensitive to "flush" cleaving restriction enzyme.

Fouteen "flush"-ended segments originate from the action of the restriction endonuclease Hae III of Haemophilus aegiptius on the DNA of the colicinogenic factor ColE 1 (A. Oka and M. Takanami, Nature, 264, 191, 1976). They are joined by the T4 polynucleotide ligase. The reaction can be monitored by gel electrophoresis, electron microscopy and resistance to phosphatase of the 5'-32P labelled ends. The joined products are a random recombination of the original segments, and can be cleaved by the same Hae III endonuclease to restore the exact electrophoretic pattern of the Hae III-cut ColE 1 DNA. In a properly diluted mixture of 5'-32P segments treated with T4 ligase, the level of phosphatase resistance is very close to the frequency of circle-formation as determined by electron microscopy: thus, the joining of the "flush"-ends involves the formation of circular structures covalently closed in both strands.
