Electron transfer (ET) rate kinetics through n-alkanethiol self-assembled monolayers (SAMs) of alkanethiols of different chain lengths [Me(CH2)nSH; n=8, 10, 11, 15] on Au and Hg surfaces and ferrocene (Fc)-terminated SAMs (poly-norbornylogous and HS(CH2)12CONHCH2Fc) on Au were studied using cyclic voltammetry and scanning electrochemical microscopy (SECM). The SECM results allow determination o...

In this issue of Blood, Safeukui et al have come to grips with an important issue in red blood cell (RBC) biology.1 Their study deals not only with the mechanism of RBC removal in diseases like hereditary spherocytosis (HS) and autoimmune hemolytic anemia, but also with RBC senescence.

Background This study aimed to compare the effects of combined endurance-resistance training (CT) versus endurance training (ET) on some cardiovascular markers in patients with heart failure after percutaneous coronary intervention (PCI). Materials and Methods The study applied a randomized, controlled design in which 75 patients with heart failure who had undergone PCI were randomly assigned...

The solubility of humic substances (HS) increases with pH. However, when in the presence of appropriate concentrations of transition metals in solution, soluble HS flocculate as a consequence of the aggregation processes promoted by the metallic ions. This is of great environmental interest as HS can retain large amounts of metallic ions at low pH. They can also form soluble complexes with thes...

To understand the evolution of premating signals in moths, it is important to know the genetic basis of these signals. We conducted Quantitative Trait Locus (QTL) analysis by hybridizing two noctuid moth species, Heliothis virescens (Hv) and Heliothis subflexa (Hs), and backcrossing the F(1) females to males of both parental species. One of these backcrosses (F(1) x Hs) was a biological replica...
