This paper investigates face perception in a visual agnosic and prosopagnosic patient (SB). Despite very extensive lesions of visual areas, SB remains capable of some visual processing [Brain 125 (2002) 58]. However, in everyday situations SB does not exhibit signs of specific face recognition. To investigate how SB may process faces, we tested two hypotheses. According to the 'spared module hy...

Tin oxide, SnO2, is a wide-band gap semiconductor. It is widely used in electronic devices. When doped with F, Sb, or Mo it becomes a conductor. In the case of antimony doping it was evidenced that the conductivity was not linearly dependent on the doping level [1]. So, there is an inevitable interest to understand this phenomenon. Recently a structural study of hydrothermally prepared nanocrys...

Traits of interest to evolutionary biologists often have complex genetic architectures, the nature of which can confound traditional experimental study at single levels of analysis. In the fire ant Solenopsis invicta, the presence of a Mendelian 'supergene' is both necessary and sufficient to induce a shift in a fundamental property of social organization, from single-queen (monogyne) to multip...

Poly(ethylene glycol) (PEG) possessing a sulfobetaine (SB) moiety at one end and a pentaethylenehexamine (N6) at the other end (SB-PEG-N6) was newly synthesized as a blocking agent for immunosensing surfaces. The N6 moiety strongly coordinates on gold surfaces, facilitating the tethering of the PEG chain to the sensor chip surface, and leaves the SB moiety free. Non-specific adsorption of bovin...

OBJECTIVE This study aimed to examine the effect of sodium butyrate (SB) on growth performance, immune status, organs weights, and microarchitecture of lymphoid organs and small intestine. METHODS A total of 120, 1-d-old broiler chicks were distributed into the following four treatment groups: corn-soy based basal diet (BD) without supplement (control), or the same BD supplemented with 0.1 g/...

The orexin/hypocretin system has been implicated in multiple phases of drug addiction. Acute orexin receptor blockade with the orexin-1 receptor (OX1R) antagonist, SB-334867, has been found to reduce cocaine seeking after cocaine self-administration. As repeated drug dosing can have differential effects and is more clinically relevant than acute dosing, in the current study we examined the effe...

The emergence of antimony (Sb) resistance has jeopardized the treatment of visceral leishmaniasis in various countries. Previous studies have considered the part played by leishmanial parasites in antimony resistance, but the involvement of host factors in the clinical scenario remained to be investigated. Here we show that unlike infection with Sb-sensitive (Sbs) Leishmania donovani, infection...

Even though antimony (Sb) and arsenic (As) are chemical analogs, differences exist on how they are taken up and translocated in plants. We investigated 1) Sb uptake, efflux and speciation in arsenic hyperaccumulator Pteris vittata after 1 d exposure to 1.6 or 8 mg/L antimonite (SbIII) or antimonate (SbV), 2) Sb uptake by PV accessions from Florida, China, and Brazil after 7 d exposure to 8 mg/L...
