Fermentation of fructooligosaccharides (FOS) and other oligosaccharides has been suggested to be an important property for the selection of bacterial strains used as probiotics. However, little information is available on FOS transport and metabolism by lactic acid bacteria and other probiotic bacteria. The objectives of this research were to identify and characterize the FOS transport system o...

Governments and donors often promote farmer organizations (FOs) in the implementation of their agricultural development programs. Yet, there is a lot uncertainty whether externally supported FOs provide benefits beyond channelling This paper uses Propensity Score Matching (PSM) representative data from 4,074 Zambian households to estimate FO impacts on members, with without controlling for nati...

Abstract Accuracy of fish growth estimates depends greatly on how samples are collected. A total three common sampling strategies random, fixed otolith (FOS), and proportional (POS). Random is inefficient rarely random. While POS has been shown to produce more accurate compared FOS under ideal conditions, it unclear variables such as sample size, fishery selectivity, fishing mortality influence...

Jun and Fos nuclear oncoproteins form a complex that regulates transcription from promoters containing activator protein AP-1 binding sites. The leucine-zipper and basic-region domains of both Fos and Jun are necessary for formation of the heterodimer that binds to DNA. Reciprocal mutations in the basic region of Fos or Jun can influence the binding of the heterodimer to DNA, implying a symmetr...

The ability of luteinizing hormone-releasing hormone (LHRH) neurons to express the oncogene c-fos was examined during the estrous cycle in rats. The immunocytochemical localization of the c-fos-encoded antigen, Fos, was coupled with the immunocytochemical localization of LHRH. LHRH neurons showed no Fos immunoreactivity during diestrus-1, diestrus-2, estrus, or the morning of proestrus. However...

The temporal and spatial expression pattern of Fos protein in spinal dorsal horn neurons was examined by immunohistochemistry in rats with chronic constriction injury (CCI) to the sciatic nerve. In normal animals, a few Fos-immunoreactive (-IR) neurons were detected in the dorsal horn of the lumbar spinal cord. Following induction of CCI, a very large number of Fos-IR neurons appeared in the sp...

BACKGROUND During mammalian protein N-glycosylation, 20% of all dolichol-linked oligosaccharides (LLO) appear as free oligosaccharides (fOS) bearing the di-N-acetylchitobiose (fOSGN2), or a single N-acetylglucosamine (fOSGN), moiety at their reducing termini. After sequential trimming by cytosolic endo beta-N-acetylglucosaminidase (ENGase) and Man2c1 mannosidase, cytosolic fOS are transported i...

The fosABCDXE operon encodes components of a putative fructose/mannose phosphoenolpyruvate-dependent phosphotransferase system and a beta-fructosidase precursor (FosE) that are involved in the fructooligosaccharide (FOS) utilization pathway of Lactobacillus paracasei 1195. The presence of an N-terminal signal peptide sequence and an LPQAG cell wall anchor motif in the C-terminal region of the d...

We present evidence that the fos oncogene encodes a transcriptional trans-activation function. trans-activation was assayed by cotransfection into NIH 3T3 mouse fibroblasts of v-fos DNA containing plasmids together with a plasmid containing a test promoter. Three v-fos DNAs were used: (i) pFBR-1, a plasmid containing the FBR proviral sequences; (ii) pFBJ-2, a plasmid harboring the FBJ proviral ...
