Public Awareness and Perceptions of Colorectal Cancer Prevention: a Cross-Sectional Survey.

We aimed to investigate awareness of colorectal cancer (CRC) lifestyle risk factors, willingness to participate in CRC screening, and preferences concerning channels for information on CRC prevention in the general population, including the target age of the upcoming Norwegian national CRC screening program. The present study was a cross-sectional online survey of adults aged 39 to 55 years registered as Kantar Web Panel respondents in Norway. The survey included demographic characteristics, multiple choice knowledge questions of lifestyle risk factors for CRC, attitudes towards CRC screening, and preferred channels for receiving information on CRC prevention.

'This is not psychoanalysis': on the stony way of the Danish Psychoanalytical Society.

When Freud founded the International Psychoanalytical Association (IPA), he wanted a network of local groups responsible for psychoanalytic training. The groups would function as 'headquarters whose business it would be to declare: "All this nonsense is nothing to do with analysis; this is not psychoanalysis".' Today, with psychoanalytic pluralism, Tuckett (in press) has asked 'Does anything go?' He has pointed out that the psychoanalytic community has been increasingly willing to accept within its ranks apparently very varied approaches to theory and practice, and that this increasing diversity has many negative consequences for psychoanalytic institutions and especially for training schemas.

Vascular nursing Internet resources: tools for cyberspace.

An older, more complex patient population, rapidly changing treatment modalities, and nontraditional venues for health care delivery have become commonplace in managing patients with vascular disorders. The delay in dissemination of information by conventional publishing and problems in accessibility create obstacles for nurses caring for this high-risk population. The Internet provides us with many valuable resources in addressing this problem.

In vitro evaluations of condoms with and without nonoxynol 9 as physical and chemical barriers against Chlamydia trachomatis, herpes simplex virus type 2, and human immunodeficiency virus.

Simulated in vitro intercourse conditions demonstrated that unlubricated latex condoms provide an effective physical barrier to high concentrations of Chlamydia trachomatis, herpes simplex virus type 2, and human immunodeficiency virus. However, since condoms can be damaged after manufacturing inspection and prior to use, latex condoms alone should not be perceived as absolute protection against STDs. Nonoxynol 9 used in conjunction with condoms provided additional, yet still not foolproof, protection against the three viruses.

Importance of the hour of sampling in the lymphoblastic transformation assay of sheep peripheral blood lymphocytes.

This paper describes the effect of the nycthemeral cycle on the lymphocyte response of sheep to different mitogens (PHA, Con A and PWM). A considerable decline in the lymphocyte response was evident in the afternoon and early in the morning in all 6 animals tested. Three peak responses were identified during a 24 hour study period, at 14.

Blastogenic response of peripheral blood lymphocytes from multiparous pregnant ewes.

The immunocompetence of pregnant multiparous ewes was investigated with respect to the blastogenic response of peripheral blood lymphocytes of (PBL) to three mitogens: PHA, Con A, and PWM. The profile of PBL responses shows 1) progressive suppression at 36 and 66 days of gestation, 2) enhanced response at 97 days of gestation, which approaches the mean values observed at the premating period, and 3) a redecline of the response at 137 days of gestation to depressed values lower than observed at 36 and 66 days of gestation. The results suggest that mitogen-treated lymphocytes were depressed and that the immunodepressive factor(s), which can influence lymphocytes at the systemic level, may be involved in the maintenance of the ovine fetal semiallograft.

Lymphoblastic transformation assay of sheep peripheral blood lymphocytes: a new rapid and easy-to-read technique.

A new micro-method was used to evaluate in vitro sensitivity of ovine peripheral blood lymphocytes (PBL) to different non specific mitogens (pHA, Con A, PWM) and to investigate the interest of a colorimetric assay for measurement of transformed lymphocytes. The results showed that sheep PBL in flat-bottomed microplates responded optimally at a cell density of 8 X 10(6) cells/ml to PHA (2.5 micrograms/ml), Con A (5 micrograms/ml) and PWM (5 micrograms/ml).

[Aspergillus ochraceus Wilhelm toxins. IV. -- Toxicity in rat by prolonged oral administration of ochratoxin A (author's transl)].

Adult male and female rats are given oral doses of 0.25 to 8 mg/kg of ochratoxin A daily for 10 days. This study confirms the intoxication symptomatology and weight loss observed in rat and mouse after sole administration of toxins.
