Attachment, Social Value Orientation, Sensation Seeking, and Bullying in Early Adolescence.

In this study, bullying is examined in light of the "prosocial security hypothesis"- i.e., the hypothesis that insecure attachment, with temperamental dispositions such as sensation seeking, may foster individualistic, competitive value orientations and problem behaviors.

[The maniac-depressive psychosis in the Opera].

There's a brief mention on the origins of the operatic genre, to get then completely into the madness in the opera, describing a close relation between the sung drama and Psychiatrics studying mind sufferings which might have or not a characteristic anatomical substractum. There's a special focus in the illness of certain opera characters.

Distinct roles for RAG-1 in the initiation of V(D)J recombination and in the resolution of coding ends.

Although RAG-1 and RAG-2 have been shown to be indispensible for V(D)J recombination, their exact role in this reaction remains unclear. Co-transfecting RAG-1 and RAG-2 expression vectors into NIH3T3 fibroblasts confers V(D)J recombination activity to these otherwise recombinationally inactive cells. In this report we have found that in transient transfections of mouse NIH3T3 fibroblasts with RAG-1 and RAG-2 and the appropriate recombination substrates, one RAG-1 expression vector, pRAG-1A, is capable of yielding both signal joints and coding joints, while another RAG-1 expression vector, pRAG-1B, yields only signal joints.

V(D)J recombination in mammalian cell mutants defective in DNA double-strand break repair.

V(D)J recombination has been examined in several X-ray-sensitive and double-strand break repair-deficient Chinese hamster cell mutants. Signal joint formation was affected in four mutants (xrs 5, XR-1, V-3, and XR-V9B cells, representing complementation groups 1 through 4, respectively) defective in DNA double-strand break rejoining. Among these four, V-3 and XR-V9B were the most severely affected.

A regulatory element that mediates co-operation between a PEA3-AP-1 element and an AP-1 site is required for phorbol ester induction of urokinase enhancer activity in HepG2 hepatoma cells.

We have characterized a transcriptional enhancer of the human urokinase-type plasminogen activator (uPA) gene and found a regulatory element required for co-operation between a PEA3--AP-1 element and an AP-1 site in the enhancer. We designated this regulatory element co-operation mediator (COM). Both the PEA3--AP-1 element, the AP-1 site and the COM are required for efficient phorbol ester induction of transcription from the uPA promoter in the HepG2 hepatoma cell line.

[Local pseudocancerous inflammatory polyposis in Crohn's disease of the colon. Usefulness of coloscopy (author's transl)].

In Crohn's granulomatous colitis large pseudopolyps may produce local lesions with radiological images resembling cancer. In the case reported here, three successive lesions of similar radiological appearance located on different sites were found on post-operative examination to be proliferative pseudopolyps adjacent to typical granulomas. In all previously published cases, even when the patient was known to have Crohn's disease colectomy was invariably performed, probably for fear of a malignant tumour.

[Histoenzymatic study of the effects of aluminium phosphate on the gastric mucosa (author's transl)].

Gastric biopsies were performed before and after a 1-month aluminium phosphate gel treatment on 12 patients with gastritis or peptic ulcer requiring endoscopy. The sections were stained with various dyes used in histoenzymatic techniques, and colour intensity was evaluated double-blind by means of 0 to 5 scores. Compared with pretreatment levels, there was a statistically significant rise in PAS-toluidine blue activity, which measures mucus secretion (p less than 0.

[Double contrast barium enema-colonoscopy. Comparative diagnostic value in 73 patients (author's transl)].

Double contrast barium enema and colonoscopy are great value in the diagnosis of lesions of the colon, especially polyps. This study involved 73 patients. The results were in agreement in 71,2% of cases and disagreed in 23,3%.

[Importance of endoscopy with biopsy in gastroduodenal amyloidosis. Apropos of 5 cases].

The authors report five cases of gastric amyloidosis in addition of the fourty three published cases. These cases was polyvisceral forms, 4 times primitive and 1 time secondary to a psoriasic rheumatism. Three times only the patients had complaints of digestive tract.

[Gastrointestinal haemorrhage related to portal hypertension. The clinician's and the endoscopist's viewpoint (author's transl)].

The origin of bleeding in 54 patients was determined by fibroscopy in 36 cases. In 29 (80%) it was due to oesophageal varices. Such ulceration of oesophageal varices is the chief cause of bleeding (80% of cases).
