LogicWeb has traditionally lacked devices for expressing mutually exclusive clauses. We address this limitation by adopting choice-conjunctive clauses of the form D0&D1 where D0,D1 are Horn clauses and & is a linear logic connective. Solving a goal G using D0&D1 – pv(D0&D1, G) – has the following operational semantics: choose a successful one between pv(D0, G) and pv(D1, G). In other words, if ...

Transcript accumulation and translation of psbA as well as processing of the D1 precursor protein were investigated in relation to chlorophyll availability in vivo in cyanobacterial strains lacking photosystem I (PS I). The psbA transcript level was almost independent of chlorophyll availability and was approximately 3-fold lower in darkness than in continuous light (5 microE m-2 s-1). Upon ill...

The dopaminergic and renin-angiotensin systems interact to regulate blood pressure. Because this interaction may be perturbed in genetic hypertension, we studied D1 dopamine and AT1 angiotensin receptors in immortalized renal proximal tubule (RPT) and A10 aortic vascular smooth muscle cells. In normotensive Wistar-Kyoto (WKY) rats, the D1-like agonist fenoldopam increased D1 receptors but decre...

Cyclin D1, an important component of cell cycle and a protein with known oncogenic potential, is over expressed in mantle cell lymphoma (MCL). MCL is a distinct clinical pathologic subtype of B cell non-Hodgkin’s lymphoma often associated with poor prognosis. New therapeutic approaches based on boosting anti-tumor immunity are being developed. Targeting cyclin D1 for MCL is rendering an interes...

In this study, we evaluated the clinical performance of anti-β2-glycoprotein 1 domain 1 antibodies (aβ2GP1-D1) in the diagnosis of antiphospholipid syndrome (APS). Sera from 229 subjects were tested, including 35 patients with primary APS, 51 patients with APS associated to other diseases, 30 patients with non-APS thrombosis, 32 patients with non-APS pregnancy-related morbidity, 42 patients wit...

Several studies have shown that the level of dopaminergic transmission and D1 receptor signaling is crucial for working memory (WM) in the prefrontal cortex (PFC) of mammals. Thus, hyper- or hypostimulation of prefrontal D1 receptors are pathophysiological findings often involved in cognitive and WM impairments. These observations can be mimicked by supranormal stimulation or inhibition with D1...

MAGE-D1, also known as NRAGE or Dlxin-1, is a member of the MAGE family of proteins. It interacts with multiple adaptors and mediates various cellular functions such as regulation of apoptosis, transcription, cell cycle, cell adhesion and angiogenesis. In this study, we evaluated the effect of MAGE-D1 plasmid transfection on the growth, migration and invasion of breast cancer cells. MTT assay a...

Ursodeoxycholic (UDCA) and tauroursodeoxycholic (TUDCA) acids modulate apoptosis and regulate cell-cycle effectors, including cyclin D1. In contrast, deoxycholic acid (DCA) induces cell death and cyclin D1. In this study, we explored the role of cyclin D1 in DCA-induced toxicity and further elucidated the antiapoptotic function of UDCA and TUDCA in primary rat hepatocytes. Cells were incubated ...

Let In be the (big) diagonal ideal of (C). Haiman proved that the q, t-Catalan number is the Hilbert series of the graded vector space Mn = ⊕ d1,d2 (Mn)d1,d2 spanned by a minimal set of generators for In. We give simple upper bounds on dim (Mn)d1,d2 in terms of partition numbers, and find all bi-degrees (d1, d2) such that dim (Mn)d1,d2 achieve the upper bounds. For such bi-degrees, we also find...

The initiation and growth of hepatocellular carcinoma (HCC) are closely linked to chronic inflammation. Not only is cyclin D1 overexpressed, but it is also related to aggressive progression in HCC. However, the mechanism of expression cyclin D1, a cell-cycle regulator of paramount importance, in the tumor microenvironment remains unknown. Here, we investigated the mechanism of cyclin D1 express...
