Intramolecular chain diffusion is an elementary process in the conformational fluctuations of the DNA hairpin-loop. We have studied the temperature and viscosity dependence of a model DNA hairpin-loop by FRET (fluorescence resonance energy transfer) fluctuation spectroscopy (FRETfs). Apparent thermodynamic parameters were obtained by analyzing the correlation amplitude through a two-state model...
دشت بم با وسعتی حدود 4357 کیلومترمربع، با مختصات جغرافیایی ً15 و57? تا ?30 و 59? طول شرقی و?30 و28? تا ?45 و29? عرض شمالی در جنوب شرقی کرمان واقع شده است. در این مطالعه جهت تعیین کیفیت آب های زیرزمینی منطقه 23 نمونه از چاه های در حال پمپاژ برداشت گردید و غلظت یون های کلسیم، منیزیم، پتاسیم، کلر، سولفات، بی کربنات و همچنین فلزات سنگین شامل سرب، سلنیوم، آهن و ارسنیک اندازه گیری گردید. سپس نقشه-های ...
OBJECTIVE To evaluate the effect of a diabetes-management program for patients with type 2 diabetes and related comorbidities on acute healthcare utilisation and costs. METHODS This was a retrospective administrative dataset analysis using data for patients enrolled from 2007 to 2008. Inpatient admissions for diabetes-related conditions were compared before, during and following enrolment. Co...
beta-Adrenergic receptors and the inhibitory GTP-binding protein, Gi of the adenylate cyclase system were reconstituted into phospholipid vesicles by the method described previously for reconstituting receptors and the stimulatory GTP-binding protein, Gs (Brandt, D. R., Asano, T., Pedersen, S. E., and Ross, E. M. (1983) Biochemistry 22, 4357-4362). In the receptor-Gi vesicles, beta-adrenergic a...
Helminthosporium sacchari infects certain clones of sugar cane and produces a toxin with the same plant selectivity as the fungus itself. The toxin was purified by use of activated charcoal plus thin layer, gel, and ion exchange chromatography. Gas chromatography (GC) of a trimethylsilyl derivative of toxin gave a single peak. Toxin was characterized by GC, mass spectroscopy (MS), and NMR spect...
In this study we analyzed Spanish Post-Heart-Transplant Tumour Registry data for adult heart transplantation (HT) patients since 1984. Median post-HT follow-up of 4357 patients was 6.7 years. Lung cancer (mainly squamous cell or adenocarcinoma) was diagnosed in 102 (14.0% of patients developing cancers) a mean 6.4 years post-HT. Incidence increased with age at HT from 149 per 100 000 person-yea...
It has been recently demonstrated that circulating microbial products are responsible for a systemic immune activation in individuals infected with HIV-type 1. Bacterial products carry structural conserved motifs recognized by TLRs. Some TLR members are expressed in primary human CD4 T cells but the precise functional role played by these pattern recognition receptors is still imprecise. In thi...
SUMMARY The concern over medicolegal liability is pervasive among physicians. We sought, through an email survey to the members of the ASNR, to assess the experience with and attitudes about the medicolegal environment among neuroradiologists. Of 4357 physicians surveyed, 904 answered at least 1 of the questions in the survey; 449 of 904 (49.7%) had been sued: 180 (44.9%) had been sued once, 11...
Bacteria were isolated from flowers and bark of apple and pear trees at three places in Australia. In Victoria, Tasmania and Queensland, strains with white colonies on nutrient agar were screened for dome-shaped colony morphology on agar with sucrose and were found to be closely related by several criteria. The isolates were not pathogenic on apples or pears. They were characterized by a polyph...
