Triple negative breast cancer (TNBC) is an aggressive subtype of breast cancer that is associated with a poor prognosis and for which no targeted therapies currently exist. In order to improve preclinical testing for TNBC that relies primarily on using human xenografts in immunodeficient mice, we have developed a novel immunocompetent syngeneic murine tumor transplant model for basal-like tripl...

Background: The National Eye Institute 39-Question Visual Function Questionnaire (NEI VFQ-39) is an indicator of vision-related quality of life (QoL). The NEI VFQ-39 is used to assess the QoL in patients with non-infectious posterior uveitis, intermediate uveitis, or panuveitis, treated with subconjunctival (SCJ) or intravitreal (IVT) sirolimus as an immunomodulatory therapeutic (IMT) agent, de...

To report the tolerance of indinavir combined with ritonavir (IDV/r 800/100 mg) twice daily (bid) in sub-Saharan African HIV-infected adults. HAART-naives patients started zidovudine plus lamivudine plus IDV/r 800/100 mg bid. Follow-up included standardized documentation of morbidity, CD4(+) cell count, creatininemia, plasma HIV-1 RNA, and IDV minimal plasma concentration (C(min)) measurements ...

BACKGROUND AND OBJECTIVES Different experimental models have been used to illustrate hemodynamic and metabolic changes during hemorrhagic shock. This study aimed at observing hemodynamic and metabolic behaviors during a sequential and progressive model of hemorrhagic shock in dogs to determine which indices are earlier changed. METHODS The study involved 13 dogs under total intravenous anesth...

Acidovorax citrulli causes bacterial fruit blotch (BFB) of cucurbits, a disease that threatens the cucurbit industry worldwide. Despite the economic importance of BFB, little is known about pathogenicity and fitness strategies of the bacterium. We have observed the phenomenon of phenotypic variation in A. citrulli. Here we report the characterization of phenotypic variants (PVs) of two strains,...

INTRODUCTION Prevalence of iron deficiency (ID) at intensive care (ICU) admission is around 25 to 40%. Blood losses are important during ICU stay, leading to iron losses, but prevalence of ID at ICU discharge is unknown. ID has been associated with fatigue and muscular weakness, and may thus impair post-ICU rehabilitation. This study assessed ID prevalence at ICU discharge, day 28 (D28) and six...

Although two in vitro cultivation methods have been reported, discrimination of infectious human norovirus particles for study of viral inactivation is still a challenge, as both rely on reverse transcriptase quantitative PCR. Histo-blood group antigen (HBGA) binding assays serve as a proxy for estimation of infectious particles; however, they are costly and difficult to purify/modify. Some evi...

Based on the following observations we propose that the cytoplasmic loop between trans-membrane segments M6 and M7 (L6/7) of the a subunit of Na,KATPase acts as an entrance port for Na and K ions. 1) In defined conditions chymotrypsin specifically cleaves L6/7 in the M5/M6 fragment of 19-kDa membranes, produced by extensive proteolysis of Na,K-ATPase, and in parallel inactivates Rb occlusion. 2...

Cation-chloride cotransporters, including the Na-K-Cl cotransporter, play an important role in epithelial ion transport in insects. We have determined the tissue distribution of Manduca sexta bumetanide sensitive cotransporter (masBSC), a putative Na-K-Cl cotransporter that was originally cloned from M. sexta Malpighian tubules. We developed a polyclonal antibody (M6) against a C-terminal fragm...
