The design of robust new interfaces that process conversational speech is a challenging research direction largely because users’ spoken language is so variable, which is especially true of children. The present research explored whether children’s response latencies before initiating a conversational turn converge with those heard in the text-to-speech (TTS) of a computer partner. A study was ...

We developed a chiral 1,1'-bi-2-naphthol-bridged imidazole dimer possessing 100 μs fast photochromism and high fatigue resistance. It offers great opportunities for the practical applications to fast photoresponsive chiral dopants, invisible security materials and optical trigger molecules to induce the dynamic structural changes in biological matters.

Concomitant inhibition of multiple cancer-driving kinases is an established strategy to improve the durability of clinical responses to targeted therapies. The difficulty of discovering kinase inhibitors with an appropriate multitarget profile has, however, necessitated the application of combination therapies, which can pose major clinical development challenges. Epigenetic reader domains of t...

Various epoxides are converted to their corresponding thiiranes in excellent yields with ammonium thiocyanate and thiourea under non-aqueous conditions in the presence of catalytic amounts of Bi(TFA)3 and Bi(OTf)3.

Introduction Breast cancer continues to be an important health problem. Early detection is needed to improve prognosis and significantly reduce women mortality. Computer-Aided Diagnosis systems (CAD) can help radiologist to improve their ability to detect and classify breast lesions. However, automated interpretation of mammogram lesions still remains very difficult. Some of the reasons are the...

Scavenger receptor class B type I (SR-BI) mediates the selective uptake of HDL cholesteryl esters (CEs) and facilitates the efflux of unesterified cholesterol. SR-BI expression in macrophages presumably plays a role in atherosclerosis. The role of SR-BI for selective CE uptake and cholesterol efflux in macrophages was explored. Macrophages and HDL originated from wild-type (WT) or SR-BI knockou...

Ultrasound imaging plays an important role in breast lesion differentiation. However, diagnostic accuracy depends on ultrasonographer experience. Various computer aided diagnosis systems has been developed to improve breast cancer detection and reduce the number of unnecessary biopsies. In this study, our aim was to improve breast lesion classification based on the BI-RADS (Breast Imaging Repor...

Infection of hepatocytes by Plasmodium falciparum sporozoites requires the host tetraspanin CD81. CD81 is also predicted to be a coreceptor, along with scavenger receptor BI (SR-BI), for hepatitis C virus. Using SR-BI-knockout, SR-BI-hypomorphic and SR-BI-transgenic primary hepatocytes, as well as specific SR-BI-blocking antibodies, we demonstrate that SR-BI significantly boosts hepatocyte perm...
