This article explores the state of the art in theories of special divine action by means of a study of the Divine Action Project (DAP) co-sponsored by the Vatican Observatory and the Center for Theology and the Natural Sciences in Berkeley. The basic aim is to introduce the DAP and to summarize its results, especially as these were compiled in the final “capstone” meeting of the DAP, and drawin...

It has been shown (a) that the inhibition of Lactobacillus casei by high concentrations of 2,6-diaminopurine (2,6-DAP) in a folic acid-containing medium is reversible only by adenine, while in a thymine-containing medium adenine is more effective than other purines in restoring growth (l), (b) that 2,6-DAP is extensively utilized as a precursor of both polynucleotide adenine and polynucleotide ...

We report loss- and gain-of-function analyses that identify essential roles in development for Drosophila transcription factor AP-2. A mutagenesis screen yielded 16 lethal point mutant alleles of dAP-2. Null mutants die as adults or late pupae with a reduced proboscis, severely shortened legs (approximately 30% of normal length) lacking tarsal joints, and disruptions in the protocerebral centra...

Netrin-1 receptors UNC5H (UNC5H1-4) were originally proposed to mediate the chemorepulsive activity of netrin-1 during axonal guidance processes. However, UNC5H receptors were more recently described as dependence receptors and, as such, able to trigger apoptosis in the absence of netrin-1. They were also proposed as putative tumor suppressors. Here, we show that UNC5H2 physically interacts wit...

OBJECTIVE To estimate and compare radiation exposure during transforaminal fluoroscopy-guided epidural steroid injection (TFESI) at different vertebral levels. MATERIALS AND METHODS Fluoroscopy-guided TFESI was performed in 181 patients. The patients were categorized into three groups according to the injected lumbosacral nerve level of L2-4, L5, or S1. Fluoroscopy time (FT) and dose area pro...

Among the aminopyridines, 3,4-diaminopyridine (DAP) is a more effective K+ channel blocker than is 4-aminopyridine (4-AP), and, furthermore, DAP enhances neuromuscular transmission. Because 4-AP improves muscle contractility, we hypothesized that DAP would also increase force and, in addition, ameliorate fatigue and improve the neurotransmission failure component of fatigue. Rat diaphragm strip...

Endocarditis is a rare but serious manifestation of Listeria monocytogenes (LM). However, the optimal treatment strategy for LM endocarditis has yet to be established. Current antibiotic strategies for listeriosis include penicillin G or ampicillin (AMP) monotherapy, or AMP + gentamicin combination therapy which is often favored for endocarditis. The primary objective of our investigation was t...

This paper documents the key anatomical features during the development of P. armeniacum zygotic embryos and their ability to germinate asymbiotically in vitro. This study also examines the effect of media and seed pretreatments on seed germination and subsequent seedling growth. Seeds collected from pods 45 days after pollination (DAP) did not germinate while 95 DAP seeds displayed the highest...

The dipeptidyl aminopeptidase BII (DAP BII) belongs to a serine peptidase family, S46. The amino acid sequence of the catalytic unit of DAP BII exhibits significant similarity to those of clan PA endopeptidases, such as chymotrypsin. However, the molecular mechanism of the exopeptidase activity of family S46 peptidase is unknown. Here, we report crystal structures of DAP BII. DAP BII contains a...

a, e-Diaminopimelic acid was first isolated from acid hydrolyzates of Corynebacterium diphtheriae by Work (1951). Subsequent studies by Dewey and Work (1952) and by Davis (1952) have demonstrated that a, e-diaminopimelic acid (DAP) can be decarboxylated to lysine and that the path of lysine synthesis apparently involves DAP as an intermediate. Davis (1952) reported that a mutant strain of Esche...
