ft-sers (fourier transform surface enhanced raman scattering) of adriamycin and its complex with dna is reported. it is shown that in agreement with previous raman studies the interaction of adriamycin  with dna takes place through an intercalation mechanism. the presence of a new band at 731 cm-1 suggests that ring d of adriamycin is not involved in the intercalation process.

copper (cu) is an essential trace element involved in normal reproduction but its over-exposure may produce some detrimental effects. the aim of this study was to investigate the effects of purslane on copper sulfate poisoning on liver structures changes. twenty eight wistar rats were randomly allocated to four treatment groups. group i) control, group ii) copper sulfate (200 mg/kg bw were appl...

BACKGROUND Patients at nutritional risk reveal an increased morbidity. Fast-track (FT) programs in colonic surgery have shown reduced complications and hospital stay. We aimed to assess the effect of FT programs on patients at nutritional risk. METHODS In a randomized trial (NCT00556790), we compared complications after open colonic surgery with either a FT program or standard care (SC). A su...

Cucurbita moschata, a cucurbit species responsive to inductive short-day (SD) photoperiods, and Zucchini yellow mosaic virus (ZYMV) were used to test whether long-distance movement of FLOWERING LOCUS T (FT) mRNA or FT is required for floral induction. Ectopic expression of FT by ZYMV was highly effective in mediating floral induction of long-day (LD)-treated plants. Moreover, the infection zone...

BACKGROUND Fourier transform infrared (FT-IR) spectroscopy is an effective tool for investigation of chemical changes at the molecular level. We previously demonstrated that FT-IR spectroscopy can reliably distinguish multiple types of carcinoma from healthy tissue. Because various stomach diseases are common, it is important to explore a noninvasive and rapid method to detect malignancy and ga...

Sets subscripted with a “+” are nonnegative, and sets subscripted with a “++” are strictly positive. We write dxen := ∑ i∈N+ i+1 2n ·1[i/2n,(i+1)/2n)(x) and bxcn := ∑ i∈N+ i 2n ·1(i/2n,(i+1)/2n](x) so dxen x and bxcn x, unless x = 0, in which case bxcn = 0 for all n. We will write (Ft)0≤t≤∞ to denote a filtration. If X• is a process taking values in (E,E ), then F t = σ ({Xs ∈ A | 0 ≤ s ≤ t, A ...

PURPOSE The filum terminale (FT) is a fibrous band that connects the conus medullaris to the posterior body of the coccyx. Considering the advances of ultrasonography (US) technology and improvements in the resolution of US images, we aimed to re-establish the US features of the normal FT in infants younger than 6 months of age. METHODS We retrospectively reviewed 30 spinal US scans, stored a...

BACKGROUND In animals, fetal testosterone (fT) plays a central role in organizing the brain and in later social behavior. In humans, exposure to atypical levels of prenatal androgens may result in masculine behavior and ability patterns. Normal inter-individual variation in fT levels has also been correlated with later sex-typed behavior. METHODS In the current study, 38 children (24 male, 14...

Flowering time, a critical adaptive trait, is modulated by several environmental cues. These external signals converge on a small set of genes that in turn mediate the flowering response. Mutant analysis and subsequent molecular studies have revealed that one of these integrator genes, FLOWERING LOCUS T (FT), responds to photoperiod and temperature cues, two environmental parameters that greatl...
