PURPOSE To identify signs occurring more frequently in retinal angiomatous proliferation (RAP) lesions compared with other types of choroidal neovascularization (CNV) in age-related macular degeneration. METHODS In this cross-sectional retrospective study, 30 patients were evaluated. These signs were correlated with the type of CNV: shunting of blood flow to the lesion by fluorescein angiogra...

The receptor-associated protein (RAP) has been identified as a chaperone regulating the expression and processing of the LDL receptor-related protein. RAP also binds to the related 600-kD multiligand endocytic receptor megalin expressed in many absorptive epithelia including renal proximal tubule. The present study examines the effect of RAP gene disruption on megalin expression and subcellular...

Glia mediate a vast array of cellular processes and are critical for nervous system development and function. Despite their immense importance in neurobiology, glia remain understudied and the molecular mechanisms that direct their differentiation are poorly understood. Rap/Fzr is the Drosophila homolog of the mammalian Cdh1, a regulatory subunit of the anaphase-promoting complex/cyclosome (APC...

To test the sensitivity and specificity of hemodynamic criteria for acute right ventricular infarction (RVI), two groups of patients with anatomically proved acute myocardial infarction and hemodynamic monitoring were studied. Group A included 22 patients acute RVI and group B, 38 with infarction confined to the left ventricle. In both groups, the closest relation between right atrial and pulmo...

Bacteriophage lambda encodes a number of genes involved in the recombinational repair of DNA double-strand breaks. The product of one of these genes, rap, has been purified. Truncated Rap proteins that copurify with the full-length form are derived, at least in part, from a rho-dependent transcription terminator located within its coding sequence. Full-length and certain truncated Rap polypepti...

We show that cell lines derived from childhood alveolar rhabdomyosarcoma (RMS) are very sensitive to the growth-inhibitory effects of the immunosuppressive agent rapamycin (RAP), compared to other human cell lines (50% inhibitory concentration range of 0.1-8 ng/mi, compared to 1280 to >10,000 ng/ml). Our data suggest that the sensitivity of RMS lines is due to RAP inhibition of insulin-like gro...

This study shows that the Bacillus anthracis pXO1 virulence plasmid carries a Rap-Phr system, BXA0205, which regulates sporulation initiation in this organism. The BXA0205Rap protein was shown to dephosphorylate the Spo0F response regulator intermediate of the phosphorelay signal transduction system that regulates the initiation of the developmental pathway in response to environmental, metabol...

Rap is one of the most salient music genres of the late twentieth and early twenty-first centuries. Gangsta rap, in particular, with its focus on urban street life, has become a dominant means of expression within contemporary African American adolescent culture. As such, it speaks directly to issues of identity, culture, violence, and nihilism—themes that permeate recent research on inner-city...

Background Adult cardiac surgery with extracorporeal circulation (ECC) is known to be associated with increased risk of blood transfusion and systemic inflammatory response leading to adverse outcomes. Modern procedures like retrograde autologous priming (RAP) may reduce these negative side effects of ECC. This randomized prospective study was initiated to assess whether RAP using specifically ...

The receptor-associated protein, RAP, is a chaperonin-like molecule that binds to two members of the low density lipoprotein receptor (LDLR) superfamily-megalin (gp330) and the LDL receptor-related protein (LRP). In F9 embryonal carcinoma cells, expression of RAP mRNA increases when differentiation is induced with retinoic acid and dibutyryl-cyclic AMP. We have investigated the expression of me...
