EP is a DNA element found in the enhancer and promoter regions of several cellular and viral genes. Previously, we have identified the DNA binding p140/c-Abl protein that specifically recognizes this element. Here we show that phosphorylation is essential for the p140/c-Abl DNA binding activity and for the formation of DNA-protein complexes. Furthermore, by 32P labeling of cells and protein purification, we demonstrate that in vivo the EP-DNA-associated p140/c-Abl is a tyrosine phosphoprotein. By employing two different c-Abl antibodies, we demonstrate the existence of two distinct c-Abl populations in cellular extracts. p140/c-Abl is quantitatively the minor population, is heavily phosphorylated at both serine and tyrosine residues, and is active in autophosphorylation reactions. 相似文献

Substitution treatment for heroin addiction, defined here as maintenance prescribing of opioid agonist drugs to opioid dependent subjects, has increased in the last decade. The recent history of substitution treatment in five countries--Canada, the U.K., Australia, Israel, and France--is reviewed. In all five countries, the critical issues around substitution treatment are similar. The first key issue concerns the balance between making treatment accessible and attractive, and minimizing diversion to the black market. The second issue concerns the role of primary health care in delivering MMT. In general, there has been increasing involvement of primary health care, with training and support for practitioners. However, there remains uncertainty and official ambivalence over whether treatment should be restricted to specialist clinics and practitioners, or available through primary care. Most importantly, underlying these issues is the problem of stigma being associated with both addiction, and with substitution treatment. The underlying problem that treatment is often at odds with community values places enormous strains on substitution treatment, and makes the treatment system vulnerable to shifting community support and abrupt, politically-driven changes in policy. 相似文献

Although hepatitis C virus (HCV) can be cleared, very few infected persons complete the treatment, resulting in disease progression and transmission. Motivational interventions effectively address health and substance-use-related conditions in many cultures. The research team piloted an HCV treatment motivational enhancement training and supervision for four counselors treating four patients in one (of 11) large methadone programs in Israel between 2007 and 2008. The counselors received a 3-day training followed by seven supervision sessions. Training included cultural and language adaptation from the original United States version to practice in Israel. Feasibility was assessed and demonstrated through training field notes and questionnaire feedback, review of taped intervention sessions for counselor proficiency and patient engagement, and patient completion of intervention sessions and piloted measures. While positive feasibility outcomes were noted, future studies should employ larger numbers of counselors and patients to assess the effectiveness of motivational enhancement in promoting HCV treatment in methadone patients. 相似文献

This study investigated association between post-traumatic stress disorder (PTSD) and a 1-year follow-up heroin use among female clients in methadone clinics in Israel. Participants were 104 Israeli female clients from four methadone clinics (Mean age = 39.09, SD = 8.61) who reported victimization to childhood sexual abuse. We tested traces in urine of these female clients for heroin a year preceding and a year following the assessment of their PTSD. Results show that 54.2% reported symptoms that accedes the DSM-IV criteria for PTSD. We found that among childhood victimized women PTSD is associated with more frequent use of heroin at a 1-year follow-up even after controlling for duration of the stay at the clinic, background, other traumatic experiences and heroin use a year prior the assessment of their PTSD. This study shows the potential long-run negative consequences of childhood sexual abuse. Not only are these sexually abused women trapped into drug dependence and addiction, they cannot break the vicious cycle of continuing the use of illicit drugs even when treated for their addiction. One major practice implication is that treatment for PTSD proven efficacious will be provided in the methadone and other drug treatment services. 相似文献

Background/aims: The research on the treatment of “dry skin syndrome” is hampered by the lack of a suitable animal model. Formerly, we developed a validated guinea pig in vivo model in which the dry skin syndrome persists at least for 1 week. We can, therefore, compare the pharmacological effectiveness of known and potential moisturizers for the treatment of dry skin syndrome. Our aim is to study whether the moisturizing efficiency of humectants depends on the solvents in which they are dissolved. Methods: “Dry skin syndrome” was induced on the shaved skin on one side of guinea pigs by daily application of 2% sodium lauryl sulphate in deionized water (SLS) for 3 days. The other shaved side was used as control. After ascertaining skin dryness, that side was treated for 6 days with glycerol or 1,2‐hexanediol in different solvents: water, or medium chain triglycerides (MCT) or mixtures of MCT with isopropyl alcohol in different proportions. Measurement of the in vivo moisturizing effect was carried out by a Corneometer CM 825®; erythema was measured by a Mexameter MX 16®. Results: Treatments with glycerol (1M) in water reversed the skin dryness shown by both instruments. When dissolving glycerol in MCT, no moisturizing effect was found, probably because glycerol does not dissolve in the oil. No moisturizing effect was found with different combinations of glycerol in the mixtures of MCT and isopropyl alcohol. No moisturizing effect was found using another polyol moisturizer: 1,2 hexanediol (1M) dissolved in MCT oil. Glycerol or 1,2‐hexanediol abolished the erythema only when they were dissolved in water alone. Conclusion: Polyol moisturizers such as glycerol or 1,2‐hexanediol do not act in the presence of oils against the sodium lauryl sulphate‐induced dry skin in our guinea pig model. Since in an oil‐in‐water (O/W) emulsion, the water evaporates within several minutes, one has to question the ability of moisturizing emulsions to treat dry skin. In such instances, one cannot draw conclusions about the moisturizing efficiency of the preparation merely from the presence of the humectant. One has to study the effect of the finished preparation. 相似文献
