3-D*aza-2'-d*ozycytidin* (d(3-d*azaC)) it a structural analogu* of 2'-d*ozycytidin* (dC) and was shown to react in a different manner as a S'-triphosphate [2] and at a template nucleotide [3] on in vitro polymerization. In thit connection the tautomeric equilibrium of d(3-d*azaC) with its imino-enol form was investigated by C-NMR spsctroscopy. Using solvents with gradually changing hydrmtion pr...

The early differentiation of T helper (Th) cells is a tightly controlled and finely balanced process, which involves several factors including cytokines, transcription factors and co-stimulatory molecules. Recent studies have shown that in addition to the regulation of apoptosis, caspase activity is also needed for Th cell proliferation and activation and it might play a role in Th cell differe...

Triclosan (TCS) and triclocarban (TCC) are widely used broad spectrum bactericides that are common pollutants of waterways and soils. Methyl triclosan (mTCS) is the predominant bacterial TCS metabolite. Previous studies have shown that TCS disrupts thyroid hormone (TH) action; however, the effects of mTCS or TCC are not known. The present study uses the cultured frog tadpole tail fin biopsy (C-...

experiment on the protective role of simvastatin against ventilator-induced lung injury (VILI). Th eir results are in line with those of a relevant study published recently by our research team; we also showed that pretreatment with statins (specifi cally atorvastatin) attenuates VILI [2]. By synthesizing the fi ndings of the above contributions [1,2], one could make several points. First, give...

INTRODUCTION With the development and improvement of laparoscopic surgery, procedures have become common. However, post-operative complications occur when patients are released from hospital. These complications increase patients' morbidity and mortality. They also lead to re-hospitalization, an extended recovery period, and an increase in the cost of treatment. AIM To evaluate and determine ...

The adsorption of Th(IV) onto the surface of oxidized multi-walled carbon nanotubes (oMWCNTs) in the absence and presence of hydroxylated fullerene (C60(OH)n) and carboxylated fullerene (C60(C(COOH)₂)n) has been investigated. C60(OH)n, C60(C(COOH)₂)n and oMWCNTs have been chosen as model phases because of their representative in carbon nano-materials family. Adsorption experiments were performe...

ectomyelois ceratoniae zeller (lepidoptera.: pyralidae), is the key pest of pomegranate in iran. trichogramma wasps could be used as effective agents of biological control that can also be used effectively in ipm programs. the effect of host density on parasitism of trichogramma brassicae was studied by exposing densities of 4, 8, 10, 20, 40, 60, 80 and 120 eggs of factitious host (sitotroga ce...
