2G12 is one of only a few cloned antibodies with broadly neutralizing specificity to HIV-1 envelope proteins. Crystallographic and electron microscopic (EM) data showed that the Fab arms are locked together via a novel VH domain exchange. Both the conventional and the unprecedented additional VH-VH antigen binding sites show specificity for high mannose oligosaccharides on the silent face of gp...

UNLABELLED The critical challenge in abdominal aortic aneurysm (AAA) research is the accurate diagnosis and assessment of AAA progression. Angiogenesis is a pathologic hallmark of AAA, and CD105 is highly expressed on newly formed vessels. Our goal was to use (64)Cu-labeled anti-CD105 antibody Fab fragment for noninvasive assessment of angiogenesis in the aortic wall in a murine model of AAA. ...

In the work reported here we have shown that light chains and Fd fragments can be separated completely in propionic acid and then recombined to form Fab fragments with antibody activity. This experiment indicates that in the recombination a correct alignment of the Fd fragments and the L chains occurs to give a competent antibody site, just as occurs with the recombination of separated heavy an...

There is increasing research activity aimed at understanding the molecular mechanisms underlying the phenomenon of so-called Fab-arm exchange, which has important implications for immunotherapies involving the anti-inflammatory IgG4 antibodies, and might also be relevant to our understanding of the etiology of the newly-described IgG4-related disease. I would like to point out that “Fab”-arm ex...

The Frontal Assessment Battery (FAB) is a short neuropsychological tool aiming to assess executive functions at the bedside. Two-hundred and thirty-six normal controls were administered the FAB and three other tasks assessing attentional and executive functions. The FAB was also administered to 28 patients suffering from mild Alzheimer's disease (AD, n. 15 subjects) or frontotemporal dementia (...

Drosophila Polycomb group (PcG) proteins silence homeotic genes through binding to Polycomb group response elements (PREs). Fab-7 is a PRE-containing regulatory element from the homeotic gene Abdominal-B. When present in multiple copies in the genome, Fab-7 can induce long-distance gene contacts that enhance PcG-dependent silencing. We show here that components of the RNA interference (RNAi) ma...

The fading affect bias (FAB) refers to the negative affect associated with autobiographical events fading faster than the positive affect associated with such events, a reliable and valid valence effect established by researchers in the USA. The present study examined the idea that the FAB is a ubiquitous emotion regulating phenomenon in autobiographical memory that is present in people from a ...

In a typical FAB factory, various types of products are produced around the clock. Complex constraints and re-entrant flows make it difficult for a human scheduler to generate a production schedule based on his/her experience and knowledge. This paper introduces a simulation based FAB scheduler, SeePlan®, which was developed by the authors. A Korea based semi-conductor and LCD maker designated ...

Abstract. Negative affect associated with autobiographical events fades faster over time than positive affect. This Fading Affect Bias (FAB) has been established in the individual and interpersonal domains. Two studies tested FAB intergroup relations Muslims ( N= 76 White British non-Muslim) opposite gender N = 242 women men) as target outgroups. The results indicated that exists an context, fo...

Why are some fields and occupations more diverse than others? In this review, we describe a conceptual framework—the field-specific ability beliefs (FAB) model—that provides promising answer to question. This model proposes that gender racial/ethnic imbalances in field or occupation result part from the confluence of two beliefs: (a) belief success context requires high levels intellectual (“br...
