TL(-) mice make TL antibody when immunized with spleen or bone marrow cells from TL(+) donors, despite the fact that these cells do not express TL antigen. This has been shown to depend on maturation of TL(-) precursors, contained in the inoculum, into TL(+) cells under influence of the recipient's thymus; the differentiated TL(+) cells then evoke production of TL antibody.
We have previously reported that Cryptococcus neoformans strains are innately heteroresistant to fluconazole in vitro, producing minor, highly resistant subpopulations due to adaptive formation of disomic chromosomes. Using a mouse model, we assessed the emergence of heteroresistant clones in the brain during fluconazole treatment and found that the occurrence of heteroresistant clones in vivo ...
Little is known in the literature about thallium (Tl) exposure from naturally occurring Tl contamination. This paper draws attention to the potential health risk posed by high concentrations of naturally occurring Tl in the environment. The inhabitants of a rural area of southwest Guizhou Province, China, reside within a natural Tl accumulated environment resulting from the Tl-rich sulfide mine...
Telomere length (TL) is emerging as a biomarker for aging and survival. To evaluate factors influencing this trait, we measured TL in a large homogeneous population, estimated the heritability (h(2)), and tested for parental effects on TL variation. Our sample included 356 men and 551 women, aged 18-92 years, from large Amish families. Mean TL in leukocytes was measured by quantitative PCR (mea...
The reliable simulation of gross primary productivity (GPP) at various spatial and temporal scales is of significance to quantifying the net exchange of carbon between terrestrial ecosystems and the atmosphere. This study aimed to verify the ability of a nonlinear two-leaf model (TL-LUEn), a linear two-leaf model (TL-LUE), and a big-leaf light use efficiency model (MOD17) to simulate GPP at hal...
Leukocyte telomere length (TL) is considered a biomarker for biological aging. Shortened TL has been observed in many complex diseases, including type 2 diabetes (T2DM). Lifestyle intervention studies, e.g. the Diabetes Prevention Study (DPS), have shown a decrease in the incidence of T2DM by promoting healthy lifestyles in individuals with impaired glucose tolerance (IGT). Our aim was to study...
واکنش کمپلکسه شدن بین کاتیونهای tl+، pb+2، la+3 با لیگاند ماکروسیکلیک cb18c6 و کاتیون tl+، hg+2 با dc18c6 در سیستم دوجزئی استونیتریل - دی متیل فرمامید با استفاده از روش هدایت سنجی در دماهای مختلف بررسی شد. داده های هدایت سنجی نشان می دهند که استوکیومتری کمپلکسهای ایجاد شده بین لیگاندهای درشت حلقوی و کاتیونهای مورد مطالعه از نوع 1:1 می باشند. ثابتهای پایداری کمپلکسهای کرون اتر که با استفاده از ا...
The present study aimed to develop novel solid dispersion (SD) of tranilast (TL) using amphiphilic block copolymer, poly[MPC-co-BMA] (pMB), to improve the dissolution and pharmacokinetic behavior of TL. pMB-based SD of TL (pMB-SD/TL) with drug loading of 50% (w/w) was prepared by wet-mill technology, and the physicochemical properties were characterized in terms of morphology, crystallinity, di...
Spontaneous Tl(I)-to-Tl(III) oxidation in dynamic heterobimetallic Hg(II)/Tl(I) porphyrin complexes.
Strapped heterobimetallic Hg(II)/Tl(I) porphyrin complexes, with both metal ions bridged by the N-core in a dynamic way, undergo spontaneous Tl(I)-to-Tl(III) oxidation leading to a mono-Tl(III) complex and a mixed valence Tl(I)/Tl(III) bimetallic complex. It provides a new opportunity to tune metal ion translocations in bimetallic porphyrin systems.
