Introduction
Skin cancer is one of the most common secondary neoplasms among childhood cancer survivors. However, little evidence exists for effective interventions to promote sun safety behaviors within this population. 相似文献3.

The bone marrow constitutes a favorable environment for long-lived antibody-secreting plasma cells, providing blood-circulating antibody. Plasma cells are also present in mucosa-associated lymphoid tissue (MALT) to mediate local frontline immunity, but how plasma cell survival there is regulated is not known. Here we report that a proliferation-inducing ligand (APRIL) promoted survival of human upper and lower MALT plasma cells by upregulating expression of the antiapoptotic proteins bcl-2, bcl-xL, and mcl-1. The in situ localization of APRIL was consistent with such a prosurvival role in MALT. In upper MALT, tonsillar epithelium produced APRIL. Upon infection, APRIL production increased considerably when APRIL-secreting neutrophils recruited from the blood infiltrated the crypt epithelium. Heparan sulfate proteoglycans (HSPGs) retained secreted APRIL in the subepithelium of the infected zone to create APRIL-rich niches, wherein IgG-producing plasma cells accumulated. In lower MALT, neutrophils were the unique source of APRIL, giving rise to similar niches for IgA-producing plasmocytes in villi of lamina propria. Furthermore, we found that mucosal humoral immunity in APRIL-deficient mice is less persistent than in WT mice. Hence, production of APRIL by inflammation-recruited neutrophils may create plasma cell niches in MALT to sustain a local antibody production. 相似文献

ObjectiveTo clarify the therapeutic education program impact with multiple sclerosis patients, literature review. Highlight contents and efficacy.MethodA non-systematic review on Medline, PubMed and Cochrane library databases from 1966 to 2010 using the following keywords: “multiple sclerosis”, “self-care”, “self-management” and specific symptoms keywords. Clinical trials and randomized clinical trials, as well as literature reviews published in English, French and German will be analyzed.ResultsCounseling is a part of the non-pharmacological management of chronic illnesses such as multiple sclerosis. Symptoms’ diversity and the different clinical forms limit standardized programs of self-care management, applicable to patients. In the literature review, counseling programs have often low metrology. A behavior change with patients and medical staff could exist. To empower the patient, to reduce symptoms’ impact and to improve treatment access are the aims of educational therapy.ConclusionTherapeutic education program for multiple sclerosis patients could progress with their standardization and assessment, for each sign. To promote the educational therapy of multiple sclerosis patients, a specific training for medical staff, as specific financing are necessary. 相似文献

As the incidence of late preterm births continues to rise, health care providers need to be aware of this population's unique needs. This review focuses on the additional risks late preterm infants encounter related to unconjugated hyperbilirubinemia and the importance of breastfeeding support and follow-up. Additional, population-based studies concentrating on the late preterm infant are needed to determine more clearly the incidence of hyperbilirubinemia, with specific levels documented; incidence of ED visits and rehospitalizations related to hyperbilirubinemia; and incidence of bilirubin neurotoxicity with both short- and long-term follow-up. It is also important to study these outcomes in relation to the nature and degree of risk associated with early discharge, insufficient follow-up, and breastfeeding. Future research is needed to develop evidence-based recommendations for optimal discharge timing, counseling, and postdischarge follow-up of late preterm infants, particularly those who are breastfed, to promote safe patient care. 相似文献

Hemoglobin A2 (HbA2; alpha 2 delta 2) is a powerful inhibitor of HbS (alpha 2 beta 2(3)) polymerization. However, HbA2 levels are normally low in sickle cell patients. We show that a major reason for low delta- globin gene expression is the defective CACCC box at -90 in the delta- globin promoter. When the CACCC box defect in delta is corrected, expression of an HS2 delta /Luciferase reporter is equivalent to HS2 beta /Luciferase. Erythroid Krupple-like factor (EKLF), which binds to the CACCC box of the beta-globin gene and activates high-level expression, does not bind to the normal delta-globin promoter. Our goal is to design a modified EKLF that binds to the defective delta-globin promoter and enhances delta-globin gene expression. To test the feasibility of this strategy, we inserted the beta-globin CACCC box at - 90 of the delta-globin gene promoter to produce an HS2 delta CAC-beta construct and quantitated human delta- and beta-globin mRNA in stably transformed murine erythroleukemia (MEL) cells. delta- Globin mRNA in these cells was 22.0% +/- 9.0% of total human globin mRNA (delta/delta + beta) as compared with 3.0% +/- 1.3% in the HS2 delta-beta control. In a second set of experiments a GAL4 DNA-binding site was inserted at - 90 of the delta-globin gene to produce an HS2 delta GAL4-beta construct. This construct and a GAL4(1-147)/EKLF expression vector were stably transfected into MEL cells. delta-Globin mRNA in these cells was 27.8% +/- 7.1% of total human globin mRNA as compared with 9.9% +/- 2.5% in the HS2 delta GAL4-beta plus GAL4(1-147) control. These results show that delta-globin gene expression can be significantly increased by a modified EKLF. Based on these results, we suggest that modified EKLFs, which contain zinc fingers designed to bind specifically to the defective delta-globin CACCC box, may be useful in gene therapy approaches to increase HbA2 levels and inhibit HbS polymerization. 相似文献
