we separated platelets from whole blood and incorporated them into in-ill and te-99m agents. sn-gha, tropolone, oxine (sulphate) and hmpao were used to diffuse radionuclides into the platelets. the effects of time, temperature, ph of incubation media; volume and concentration of ionophore; and volume and activity of ln-l 13m c13 and te-99m on labeling efficiency were studied.

abstract objective removing plasma from the platelet concentrate (pc) medium could be an effective way to increase the safety of this product. the goal of this study was to compare pc stored in plasma or in an additive solution (composol) with in vitro testing. materials and methods fifty-four single donor pcs were prepared from iranian blood transfusion organization (ibto). each pc unit was di...

Government regulations to address technological risks are important for the successful development and application of nanotechnology, but there is an ongoing debate in the USA about who is responsible for the regulation of nanotechnology. In a mail survey of leading US nano-scientists, we examine scientists’ perceptions about nano-regulation, including the government level (local, national, or ...

Although liquid crystal elastomers (LCE) are a fascinating class of materials with interesting thermomechanical properties their own, the aim is to enhance performance or add new features, e.g. response external stimuli. The generally weak organic can be significantly intensified by mixing nano-sized magnetic particles into host polymer matrix. An alternative approach chemically coupling nanopa...

background the aim of this clinical trial was the assessment of safety and efficacy of submocosal and periurethral injections of peripheral blood derived autologous stem cells along with platelets, and focused on outcome for six months. methods an open, prospective study was conducted on 10 patients presenting with stress urinary incontinence. at the baseline (pre-operative), 1, 3 and 6 months ...

objective: maintaining the health of oral tissues is a major goal in dentistry. however, limitations in dental materials, instruments, procedures and medications prevent achievement of this goal. advances in nanotechnology have paved the way to approach this goal. this study reviews the advances on nanotechnology in dentistry. review of literatures: in this review study, google scholar, pubmed,...
