Estimation of genetic risk for type 1 diabetes 总被引:8,自引:0,他引:8
Ilonen J Sjöroos M Knip M Veijola R Simell O Akerblom HK Paschou P Bozas E Havarani B Malamitsi-Puchner A Thymelli J Vazeou A Bartsocas CS 《American journal of medical genetics》2002,115(1):30-36
The most important gene loci defining risk of type 1 diabetes mellitus (T1DM) are located within the HLA gene region. HLA-DQ molecules are of primary importance but HLA-DR gene products modify the risk conferred by HLA-DQ. The risk associated with an HLA genotype is defined by the particular combination of susceptible and protective alleles. The highest risk is associated with a combination of two different risk haplotypes (7% risk to develop T1DM in Finland) whereas protective genotypes covering 69% of population have a risk of less than 0.2%). The complicated analysis of HLA genotypes is simplified by strong linkage disequilibrium between HLA-DRB1, -DQA1 and -DQB1 loci. In many cases one can deduce the alleles of other loci based on determination of the alleles in one locus. Differences between various populations in the frequency of marker alleles and in the linkages between them has to be taken into account. We have developed PCR based typing methods that utilize blood spot samples, microtiter plate format and lanthanide labeled oligonucleotide probes to define HLA-DQ and -DR alleles relevant for T1DM risk. Typing is run stepwise so that after initial HLA-DQB1 typing only those samples will be further analyzed in which -DQA1 or -DRB1 typing is informative and expected to contribute to the risk estimation. This method has been used to screen more than 50,000 newborn infants in Finland over a time period of 6 years, and it has been able to identify most children who have developed T1D during the follow-up period. The efficiency of the procedure has also been tested in Finnish and Greek populations. 相似文献

This report refers to preterm birth in Ancient Greece based on mythological, historical and archeological data. The two antique goddesses, patronesses of labor and birth, Artemis and Eileithyia, cared for full-term, as well as preterm infants, among them for the mythological preterms Dionysos and Eurystheus. The former was rapidly transported by Hermes and received special care by the nymphs Hyades in a mountain cave with “incubator” properties. Historical data are related to the nine months duration of a normal pregnancy, to the definition of “Elitomina” (preterms), the lower limit of viability, the causes for preterm birth, the existence of small for gestational age infants and relevant causes, the physical examination of neonates and postpartum care. Lastly, excavations in Athens and Astypalaia discovered burials – in wells or pots – of preterm infants with gestational age 24–37 weeks. 相似文献

OBJECTIVE: IGF-I and insulin are the main regulators of intrauterine and postnatal growth. Adipose tissue secreted cytokines are implicated in intrauterine growth. The relevant function of the adipocytokine visfatin is unknown. MATERIALS AND METHODS: Serum visfatin, IGF-I and insulin levels were measured by enzyme immunoassays in 40 singleton full-term fetuses and neonates on postnatal days 1(N1) and 4 (N4). RESULTS: No significant correlations exist between visfatin and IGF-I or insulin. N1 and N4 visfatin positively correlated with customized (adjusted) birth weight centiles (r=0.511, P=0.021, and r=0.597, P=0.005, respectively). Fetal and N1 IGF-I positively correlated with customized centiles (r=0.608, P<0.001 and r=0.485, P=0.006, respectively). Fetal insulin positively correlated with customized centiles (r=0.654, P=0.021). CONCLUSIONS: Potential implication of visfatin in fetal growth is probably not mediated by IGF-I or insulin. Although a more active role cannot be excluded, visfatin may simply represent a marker of fat accumulation. 相似文献

Introduction
Vascular malformations have devastating cosmetic effects in addition to being associated with pain and bleeding. Sclerotherapy has been used as an effective therapeutic modality for the management of vascular malformations. The purpose of this case series is to describe our clinical experience of using sodium tetradecyl sulphate (STS) 3 % in the treatment of venous malformation lesions of head and neck.Materials and Methods
Thirteen patients were included in this study (three male and ten female; age range between 8 months and 54 years; mean age 18.2 years, ±SD 15.71). The patients were treated by 3 % STS intralesional injections. Of the thirteen patients treated, complete resolution occurred in four patients (28.57 %), a good response occurred in five patients (35.7 %), a moderate response in two patients (14.28 %), a mild response in two patients (14.28 %) and no response in one patient (7.14 %). The side effects encountered in all patients were pain and edema after injection which was controlled by oral analgesics and an intramuscular injection of dexamethasone. In addition, two patients developed a superficial ulceration (11.76 %) which healed uneventfully, and one patient developed ecchymosis after injection (5.88 %).Conclusion
Sclerotherapy with 3 % STS is a simple, safe, and effective modality for the treatment of venous malformations. 相似文献9.

PurposeTo set up the digital database (DDB) of various anatomical parts, skin details and retention elements in order to simplify the digital workflow of facial prostheses manufacturing; and to quantify the reproduction of skin wrinkles on the prostheses prototypes with stereolithography (SLA) and direct light processing (DLP) methods.MethodsTwo structured light scanners were used to obtain the nasal and auricle forms of 50 probands. Furthermore, the ala nasi and scapha areas were captured with the digital single lens reflex camera and saved in jpeg format. The four magnetic retention elements were remodeled in computer aided design (CAD) software. The 14 test blocks with embossed wrinkles of 0.05–0.8 mm were printed with SLA and DLP methods and afterwards analyzed by means of profilometry and confocal microscopy.ResultsThe introduced DDB allows for production of customized facial prosthesis and makes it possible to consider the integration of concrete retention elements on the CAD stage, which makes the prosthesis modelling more predictable and efficient. The obtained skin structures can be applied onto the prosthesis surface for customization. The reproduction of wrinkles from 0.1 to 0.8 mm in depth may be associated with the loss of 4.5%–11% of its profile with SLA or DLP respectively. Besides, the reproduction of 0.05 mm wrinkles may be met with up to 40% profile increasement.ConclusionsThe utilization of DDB may simplify the digital workflow of facial prostheses manufacturing. The transfer of digitally applied skin wrinkles till the prostheses’ prototypes may be associated with deviations from 11 to 40%. 相似文献
