China's Good Manufacturing Practice (GMP) standards that mainly parallel WHO standards were made compulsory in 2004. However, GMP implementation had both positive as well as negative impacts on the pharmaceutical industry, with negatives including pharmaceutical companies suffering economic hardships, poor execution of GMP standards, and sequent health scares. This report briefly describes the ...

Acholeplasma laidlawii B-PG9 was examined for 16 cytoplasmic enzymes with activity for purine salvage and interconversion. Phosphoribosyltransferase activities for adenine, guanine, xanthine, and hypoxanthine were shown. Adenine, guanine, xanthine, and hypoxanthine were ribosylated to their nucleoside. Adenosine, inosine, xanthosine, and guanosine were converted to their base. No ATP-dependent ...

Environmental signals that trigger bacterial pathogenesis and biofilm formation are mediated by changes in the level of cyclic dimeric guanosine monophosphate (c-di-GMP), a unique eubacterial second messenger. Tight regulation of cellular c-di-GMP concentration is governed by diguanylate cyclases and phosphodiesterases, which are responsible for its production and degradation, respectively. Her...

Community-based growth promotion (CBGP) delivered by community volunteers aims at enhancing the traditional growth monitoring and promotion (GMP) program delivered by community health nurses through the promotion of optimum infant and young child feeding (IYCF) leading to improved child growth. This study compared IYCF knowledge and practices among caregiver-child pairs (0-24 months) receiving ...

GMP-140 is a 140-kD granule membrane protein, found in the alpha granules of platelets and the Weibel-Palade bodies of endothelial cells, that is surface expressed on cell activation and mediates neutrophil attachment. Cloning data for GMP-140 from an endothelial library predict a soluble form of the protein, the transcription message for which is also found in platelets. In this study, we repo...

The bacterial second messenger bis-(3'-5')-cyclic diguanosine monophosphate (c-di-GMP) ubiquitously promotes bacterial biofilm formation. Intracellular pools of c-di-GMP seem to be dynamically negotiated by diguanylate cyclases (DGCs, with GGDEF domains) and specific phosphodiesterases (PDEs, with EAL or HD-GYP domains). Most bacterial species possess multiple DGCs and PDEs, often with surprisi...

Understanding the molecular properties and interactions of components within high-protein dairy powders is important in predicting rehydration performance. Raman spectroscopy was used to generate information which provided insights into between caseins micellar casein concentrate (MCC) powder formulated with varying proportions glycomacropeptide (GMP). The bands showed intense peaks at 1446 147...

The bacterial second messenger cyclic di-GMP (c-di-GMP) controls biofilm formation and other phenotypes relevant to pathogenesis. Cyclic-di-GMP is synthesized by diguanylate cyclases (DGCs). Phosphodiesterases (PDE-As) end signaling by linearizing c-di-GMP to 5'-phosphoguanylyl-(3',5')-guanosine (pGpG), which is then hydrolyzed to two GMP molecules by yet unidentified enzymes termed PDE-Bs. We ...

Vibrio cholerae senses its environment, including the surrounding bacterial community, using both the second messenger cyclic di-GMP (c-di-GMP) and quorum sensing (QS) to regulate biofilm formation and other bacterial behaviors. Cyclic di-GMP is synthesized by diguanylate cyclase (DGC) enzymes and degraded by phosphodiesterase (PDE) enzymes. V. cholerae encodes a complex network of 61 enzymes p...

Cyclic di-GMP (c-di-GMP) is a bacterial second messenger produced by GGDEF domain-containing proteins. The genome of Ehrlichia chaffeensis, an obligatory intracellular bacterium that causes human monocytic ehrlichiosis, encodes a single protein that contains a GGDEF domain, called PleD. In this study, we investigated the effects of c-di-GMP signaling on E. chaffeensis infection of the human mon...
