Abstract
If a multi-component monosugar mixture including fucose was used as the substrates for the Klebsiella oxytoca fermentation, it could offer the following two benefits simultaneously; (i) the removal of all monosugars other than fucose, and (ii) the acquisition of 2,3-butanediol (BD). To utilize such two benefits in favor of the economical efficiency of the fucose production process, it is essential to accomplish a high-purity separation between fucose and BD on the basis of a highly-economical mode. To address this issue, we aimed to develop a simulated moving bed (SMB) process for continuous-mode separation of fucose and BD with high purities. It was first found that an Amberchrom-CG71C resin could become a suitable adsorbent for the separation of interest. The intrinsic parameters of fucose and BD on such proven adsorbent were determined, and then applied to the optimal design of the fucose-BD separation SMB. The capability of the designed SMB in ensuring high purities and high yields was experimentally verified. Finally, we devised two potential strategies to make a further improvement in product concentrations and/or desorbent usage while keeping the purities and yields of fucose and BD almost unchanged. The first strategy was based on partial extract-collection and partial extract-discard, which was found to result in 33% higher BD product concentration. The second strategy was based on partial extract-collection, partial extract-recycle, and partial desorbent-port closing, which could lead to 25% lower desorbent usage, 33% higher BD product concentration, and 7% higher fucose product concentration.

Optimization of production rate, productivity, and product concentration for a simulated moving bed process aimed atfucose separation using standing-wave-design and genetic algorithm. J Chromatogr A 2018; 1575:113-121.

Abstract
The effectiveness of a simulated moving bed (SMB) technology in the continuous separation of fucose from a multi-component monosugar mixture, which stemmed from defatted microalgae, has recently been identified. To guarantee high economical efficiency of such fucose-production method, the comprehensive optimization of the relevant fucose-separation SMB process needs to be accomplished such that its production rate (Prate) and/or productivity (Prod) can be maximized while meeting the requirements on fucose product concentration (Cprod,F) and pressure drop (ΔPSMB). To resolve this issue, the SMB optimization program based on standing-wave-design method and genetic algorithm was prepared and then applied to the fucose-separation SMB optimization. It was found that the Prate, under a given particle size, could reach its maximum when the column length was selected to create a balance between the effects of the two limiting factors related to Cprod,F and ΔPSMB. It was also found that the Prate was governed by fucose yield, if the SMB would be in need of a relatively high Cprod,F; otherwise, the Prate was governed by feed flow rate. If the particle size of the SMB adsorbent was fixed at one of the commercially available ones, the SMB conditions leading to the highest Prate and the highest Prod coincided with each other. By contrast, if the particle size was included as one of optimization variables, the Prate and Prod represented a trade-off relationship. Finally, it was confirmed from the simultaneous optimization for Prate and Prod that the increase of particle size improved Prate at the cost of Prod, thereby causing the maximum Prod to be always attained at a smaller particle size than the maximum Prate regardless of the target Cprod,F level.

Abstract
Corneal wound healing often leads to the development of scar tissue with loss of transparency. Reconstitution of transparent corneal stroma depends on the regulation of the biosynthetic activities of postlesional keratocytes and also to a large extent on the limitation of matrix degradation, attributed essentially to the upregulation of matrix metalloproteases and especially MMP-9. Using a standardized method for the production of reproducible corneal lesions by burning with iodine vapors, we could show that the local application of 0.5 mg/ml L-fucose reduced significantly MMP-9 upregulation and accelerated the recovery of the epithelial layer of the cornea. The iodine vapor used in the experiments produces a rapid loss of epithelium with no or slight effect below the basement membrane. A relatively rapid regrowth of epithelium was observed. The speed of this reepithelialization was stimulated by the local application of fucose. At 48 h after burn, there was a difference between fucose-treated and control corneas (epithelial thickness was about 50 mum for fucose-treated corneas and 37 microm for control corneas). Culture media of in vivo fucose-treated corneas showed an important decrease of MMP-9 activity (-51%, n = 6, p < 0.01). It appears that the in vivo fucose treatment reduced the MMP-9 activity released in the media. This effect is significant 24 h after iodine vapor burn. In order to study the effect of fucose on normal corneas, it was added to rabbit as well as human cornea explant cultures, and the production and release of MMP-9 was determined by zymography. Fucose at a concentration of 0.5 mg/ml produced a 70% decrease of MMP-9 activity released in the medium by corneal explant cultures. Other mono- and oligosaccharides were also tested. Besides lactose, fucose-rich oligosaccharides also produced significant inhibition. Galactose, melibiose, mannose and glucose were inactive. These results justify the use of fucose for the local treatment of corneal wounds.

Abstract
The first amperometric biosensing method for the determination of L-fucose is described. L-Fucose is the objective of much current research, as it is considered as a potential marker for various pathologic disorders. Recombinant L-fucose dehydrogenase, having as cofactor beta-nicotinamide adenine dinucleotide phosphate (NAD+P), was cross-linked in a water-soluble photosensitive polymer matrix, that is, polyvinyl alcohol (PVA) modified with styrylpyridinium (SbQ), in the presence of BSA and glutaraldehyde. The resulting membrane was sandwiched between two polycarbonate membranes and was mounted in an amperometric cell. The oxidation of the enzymatically produced NADPH was monitored at a platinum anode at +0.25 V versus a silver pseudoreference electrode in the presence of ferricyanide. The system was fully optimized with respect to various analytical parameters. Regarding to the mechanical properties of the membrane and the storage stability of the immobilized enzyme, various parameters were also optimized. Several methods for the pretreatment of urine samples were investigated. Treatment of the samples with PbO2 found to eliminate the interference effect of various electroactive species exist in urine; optimum incubation time was determined since at prolonged incubation times L-fucose is also affected. Calibration curves for the direct and the mediated monitoring of NADPH were liner over the concentration ranges 0.04-1.0 mM (r2=0.9995) and 0.03-3.0 mM (r2=0.9997) fucose, respectively. The detection limits (S/N 3) were 2 and 1.5 microM fucose, respectively. The R.S.D. of the mediated biosensor is better than 1.5% (n=10, 0.5 mM fucose). The proposed biosensor correlates well with a reference enzymatic method and exhibits very good working and storage stability.

Abstract
Skin aging represents an important chapter of connective tissue aging and concerns an organ of vital importance. Here we describe the preparation as well as the biological properties of fucose-rich oligo- and polysaccharides (FROPs), composed of polymers of a trisaccharide containing galactose, acetyl galacturonic acid and fucose, from the original high molecular weight bacterial polysaccharide (Fucogel), Solabia, France). Using endoglycosidases, oligo- and polysaccharides were prepared and characterized by physical and chemical procedures. The non-reducing end-groups comprise equal amounts of galactose and fucose. The here-described biological properties are: stimulation of cell proliferation of cultured human skin fibroblasts, protection of cells against ascorbate-induced cytotoxicity due to the release of reactive oxygen species (ROS). Properties elsewhere described concern the inhibition of matrix metallo-proteinases 2 and 9 (MMP-2 and MMP-9), their expression and activation. Using fluorescein isothiocyanate (FITC)-labeled polysaccharides, their interaction with cell membranes and also their penetration and accumulation in cells, especially in the cell nucleus could be demonstrated, probably via cell-membrane receptor-mediated mechanisms. We describe some of the symptoms of skin aging and show, that the here-described polysaccharide preparations are susceptible to slow down some of the cellular and molecular mechanisms involved, partly by the mediation of the above-mentioned receptors, partly by acting directly on the regulation of gene expression.

Abstract
Fucose is the only component of glycoconjugates of vertebrates in the L-configuration. It exhibits a number of unique and interesting biological properties reviewed briefly in this article. Its constant end-standing position on glycan chains predisposes fucose to play a key role in cell-cell and cell-matrix interactions, mediated by several receptors such as those recognising the Lewis-type blood group substances, fucose-recognising lectines and the mannose-fucose receptors. Some of the as yet unstudied or less well understood properties of L-fucose were explored in the present study, as its non-enzymatic interaction with amine-groups on macromolecules, its cellular uptake attributed to specific transport mechanisms and its effect on fibroblast cell cultures. We could document the stimulation of cell-proliferation and the inhibition of MMP-expression and activation, both for MMP-2 and MMP-9. These and the other shortly reviewed properties of L-fucose may play an important role in its biological applications and actions.

Abstract
Tissue loss during ageing and age-dependent pathologies are the result of a disturbed regulation of proteolytic activities. Elastase-type endopeptidases, especially MMP-2 and -9, play an important role in this respect. Dermal fibroblast cultures and skin explant cultures were used in order to measure the efficiency of fucose and fucose-rich polysaccharides to downregulate the elastase-type endopeptidase activity. Fucose and fucose-rich polysaccharides were shown to downregulate this elastase-type activity, the basic activity and also the hyaluronan or kappa-elastin-stimulated activity. In skin explant cultures, we could demonstrate that fucose and fucose-rich polysaccharides produced an inhibition of the activation of the pro-form to the active form of MMP-9. Here, we show that mono-, di-, oligo- and polysaccharides acting on the elastin-laminin receptor and/or on the fucose-mannose receptor are efficient inhibitors of such enzymes by downregulating elastase-type endopeptidase activity, both at the level of their biosynthesis and at the level of the activation of the pro-enzymes. Fucose and fucose-rich polysaccharide preparations were shown to be efficient modulators of MMP-2 and MMP-9, activity with potential therapeutic applications in age-related pathologies accompanied by tissue loss.

Abstract
BACKGROUND This paper highlights the sometimes impressive effect of diphencyprone (DPC) sensitization on warts resistant to other treatments and is interesting in view of the fact that all the warts apparently responded, despite only a very small area being treated. METHODS A 31-year-old woman with a 5-year history of widespread facial plane warts that had proved resistant to repeated treatments with cryotherapy and topical preparations was sensitized to diphencyprone. RESULTS After application of DPC to the warts within only a 1-cm(2) area of the face, all the facial warts became inflamed and resolved, including those not actively treated. Complete clearance occurred with no recurrence. CONCLUSION DPC appears to be a valuable, safe and well-tolerated treatment for resistant viral warts and can be considered as a first line treatment. We review its use and action in this paper

Abstract
The angry back syndrome (ABS) was investigated using Trafuril cream and prostaglandin synthetase inhibitors. Trafuril produced an increase in the numbers and intensity of patch test reactions which was partly abrogated by aspirin and indomethacin. Irritant reactions were not affected. We suggest that Trafuril may increase the sensitivity of the patch testing system and that this may have useful clinical applications.

Abstract
Local application of alpha-L-fucose on the ear before elicitation of contact allergy to dinitrofluorobenzene (DNFB) in BALB/c mice results in a suppression of the contact allergic response. However, local application of alpha-L-fucose at the sensitization site on the abdominal wall before sensitizing the animals with DNFB had no inhibitory effect on contact allergy. Alpha-L-fucose has been demonstrated to inhibit lymphokine activity in vitro and manifestation of cellular immunity in vivo. Our results suggest that alpha-L-fucose suppresses contact allergy by locally inhibiting the efferent phase of the cellular immune response.
