A 52-year-old Malaysian man, a 24-year-old sub-Saharan woman, and a 28-year-old Madagascan woman (who was heterozygous for hemoglobin S) were admitted to North Hospital in Marseilles, France. Blood tests using an Advia2120i hematology analyzer (Siemens) showed no or mild anemia (109-150 g/L), normal or high mean corpuscular hemoglobin concentration (339-364 g/L), and borderline or slightly high...

A 32-year-old woman presented with an 8-month history of verrucous and suppurative skin lesions on the anogenital area. She was diagnosed with human immunodeficiency virus (HIV) infection 18 months before and was receiving antiretroviral therapy thereafter. She underwent excision and experienced recurrence of perineal warts since the age of 28 years. Clinical examination showed oval hyperchromi...

It has been shown that mice with complete deficiency of all 4.1R protein isoforms (4.1-/-) exhibit moderate hemolytic anemia, with abnormal erythrocyte morphology (spherocytosis) and decreased membrane stability. Here, we characterized the Gardos channel function in vitro and in vivo in erythrocytes of 4.1-/- mice. Compared with wild-type, the Gardos channel of 4.1-/- erythrocytes showed an inc...

Structural and functional differentiation of chro­ matin implies the search for the methods of isolation and characterization of DNA bound with chromatin fractions. Preliminary fractionation of chromatin fol­ lowed by the isolation of DNA from these fractions are the methods frequently used. The isolation procedure put forward by Strazhevskaya and Struchkov [1] makes it possible to isolate DNA ...

Flutamide (Flu) is a chemotherapeutic drug, used for the treatment of prostate cancer. It functions by interfering DNA in fast growing cells and preventing them from reproducing. The present work is focused on the interaction of Flu with single and double stranded DNA at different temperatures and at physiological pH 7.4 (human blood pH). Cyclic voltammetry, square wave voltammetry and UV–visib...

PURPOSE The purpose of this study was to evaluate and characterize the risk of anemia during the course of chemotherapy among patients with five common types of solid tumors. PATIENTS AND METHODS Patients diagnosed with incident cancers of breast, lung, colon/rectum, stomach, and ovary who received chemotherapy were identified from Kaiser Permanente Southern California Health Plan (2010-2012)...

BODIPY-clickates, F1 and F2, for the detection of Hg(2+) have been designed, synthesized and characterized. Both F1 and F2 showed hyperchromic shifts in the UV-visible spectra in response to increasing Hg(2+) concentrations. Hg(2+) ion binding caused perturbation of the emission quenching process and chelation induced enhanced bathochromic emission of F1 and F2 to 620 nm and 660 nm, respectivel...

Noncoding sequences regulate the function of mRNA and DNA. In animal mRNAs, iron responsive elements (IREs) regulate the synthesis of proteins for iron storage, uptake and red cell heme formation. Folding of the IRE was indicated previously by reactivity with chemical and enzymatic probes. 1H- and 31P-NMR spectra now confirm the IRE folding; an atypical 31P-spectrum, differential accessibility ...

Poly(tetramethylsilarylenesiloxane) derivatives having diphenylfluorene (P1) or diphenyldibenzosilole (P2) moieties were prepared via polycondensation of the corresponding disilanol monomers, that is, 2,7-bis(dimethylhydroxysilyl)-9,9diphenylfluorene (M1) and 2,7-bis(dimethylhydroxysilyl)-9,9-diphenyldibenzosilole (M2), respectively. P1 and P2 exhibited good solubility in common organic solvent...

The secondary structure of RNA in particles of two plant viruses with helical symmetry (tobacco mosaic virus (TMV) and potato virus X (PVX)) was studied by determining their RNA extinction spectra in situ. The true values of extinction of light-scattering virus suspensions were calculated by extrapolation. To determine the degree of hyperchromicity of internal RNA, the spectra of suspensions of...
