The integral cross section of the 12C(n, p)12B reaction was measured at the neutron time of flight facility n_TOF at CERN, from the reaction threshold at 13.6 MeV up to 10 GeV, by means of the combined activation and a time-offlight technique. The integral result is expressed as the number of 12B nuclei produced per single pulse of the neutron beam. A simple integral expression is given for cal...
Genetic variants of IL-18 and IL-12B may be important in immunoregulatory abnormalities, observed in the patients with Type 1 diabetes mellitus (T1DM), that contribute to individual differences in response to a treatment. Therefore, we examined the significance of IL-18-137G/C, IL-18-607C/A, and IL-12B A/C polymorphisms in Croatians (187 patients, 236 controls), not only as factors that contrib...
UNLABELLED Dengue virus (DENV) infection usually presents with mild self-limiting dengue fever (DF). Few however, would present with the more severe form of the disease, dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). In the present study, the association between IL-12B, IL-10 and TNF-α gene polymorphisms and dengue severity was investigated. METHODS A case-control study was p...
Interleukin 12 (IL-12) is a heterodimeric, pro-inflammatory cytokine that plays a central role in activation and differentiation of CD4(+) T cells into interferon-γ secreting T-helper type 1 cells. IL-12B, a gene encoding the larger subunit of active IL-12, has been reported to be down-regulated by the nuclear hormone 1α,25-dihydroxyvitamin D(3) (1α,25(OH)(2)D(3)), but the mechanism of the regu...
IL-12 has been reported to affect thymic T cell selection, but the role of IL-12 in thymic involution has not been studied. We found that in vivo, IL-12b knockout (IL-12b(-/-)) mice exhibited accelerated thymic involution compared with wild-type (WT) B6 mice. This is characterized by an increase in thymocytes with the early development stage phenotype of CD25(-)CD44(+)CD4(-)CD8(-) in aged IL-12...
A series of tribenzotriquinacene derivatives bearing three oxy-functionalised alkyl groups at the benzhydrylic bridgeheads (C-4b, C-8b and C-12b) have been synthesised. The 4b,8b,12b-triallyl derivative was used to generate the corresponding TBTQ-tris-acetaldehyde and TBTQ-tris(acetic acid), in which the functional groups stretch out from the convex rigid molecular surface. The corresponding tr...
سابقه و هدف: ویتامین 12b یکی از ضروری ترین ویتامین های مورد نیاز بدن می باشد. تظاهرات روان پزشکی بیماران دچار کمبود ویتامین 12b اغلب شامل پرخاشگری و بی قراری به همراه تحریک پذیری و گیجی، اختلال در جهت یابی، فراموشی، اختلال در تمرکز و توجه، بی خوابی، بی اشتهایی می باشد. تاخیر در درمان بیماری کمبود ویتامین 12b ممکن است باعث عوارض غیر قابل برگشت در ساختار مغز گردد. در این یک مورد بیمار مبتلا به کم...
Serpentine cord formation in BACTEC 12B medium was evaluated as a rapid method for the presumptive identification of M. tuberculosis complex. Kinyoun acid-fast stained smears were prepared from 666 positive BACTEC 12B bottles and examined for the presence or absence of serpentine cording. Cord formation had a sensitivity, specificity, positive predictive value, and negative predictive value of ...
This study illustrates the use of data envelopment analysis to benchmark mutual funds on the basis of risk-adjusted performance, load, 12b-1 plan, and expense ratios. Using the DEA methodology, we calculate an efficiency score for 189 funds on a scale of 1 to 100 by maximizing twelve month total return and minimizing beta, standard deviation, load, 12b-1 charges, and expense ratios. This study ...
We evaluated the ability of a PCR assay to identify Mycobacterium tuberculosis complex (MTBC) from positive BACTEC 12B broth cultures. A total of 107 sputum samples were processed and inoculated into Ogawa slants and BACTEC 12B vials. At a growth index (GI) > or=30, 1.0 ml of the 12B broth was removed, stored, and assayed with PCR. Molecular results were compared to those obtained by phenotypic...
