[more ▼] A new three-enzyme reaction cycle consisting of sucrose synthase, UDP glucose 4‘-epimerase, and human β-1,4-galactosyltransferase was established for the synthesis of N-acetyllactosamine (LacNAc) with in situ regeneration of UDP galactose. We found that UDP glucose 4‘-epimerase is reductively inactivated in the presence of UMP and acceptor substrates of β-1,4-galactosyltransferase. Reactivation of UDP glucose 4‘-epimerase by the transition state analogues dUDP or dTDP 6-deoxy-d-xylo-4-hexulose in combination with the repetitive batch technique enabled us to use the native enzymes for 11 days in this cycle. With 10 U of sucrose synthase, 5 U of UDP glucose 4‘-epimerase, and 1.25 U of β-1,4-galactosyltransferase, 594 mg of LacNAc could be synthesized. N-Acetyllactosamine was also subsequently converted to Neu5Acα2,6Galβl,4GlcNAc with α-2,6-sialyltransferase and CMP-Neu5Ac.

[more ▼] Abstract: The synthesis of NDP-glucose 3a-d (N= A, C, U, dU) with sucrose synthase B was combined with the enzymatic synthesis of nucleoside diphosphates 2a-d from their corresponding nucleoside monophosphates la-d by different kinases A. Further combination with recombinant dTDP-glucose 4,6-dehydratase D enabled us to synthesize dUDP-6-deoxy-alpha-D-xylo-4-hexulose 5 from ld on a preparative scale. By using the repetitive batch technique the enzymatic syntheses of nucleotide (deoxy) sugars 3a-d, 5 could be realized on a 0.1 - 0.5 g scale.

[more ▼] The kinetic translational energy released in the unimolecular fragmentation reaction C6H5Br+->C6H5++Br has been experimentally studied in the microsecond time scale and theoretically analyzed by the maximum entropy formalism. The appropriate functional form relating the actual distribution to its prior distribution (eq.2.3) involves the square root of the kinetic energy (i.e. the momentum associated with the relative translational energy). A value of 0.26+/-0.02 eV is obtained by the entropy deficiency distribution at an internal energy of 0.85 eV above the reaction threshold. From this value, it can be concluded that 77% of the transition state phase space is efficiently sampled.

[more ▼] La néphropathie ischémique est une entité de plus en plus fréquente, à cause du vieillissement de la population et du contrôle médicamenteux de l'hypertension. Une ischémie de l'ensemble de la masse rénale (sténoses serrées concernant les deux reins ou un rein unique) compromet la filtration glomérulaire et constitue une des rares formes d'insuffisance rénale chronique réversible. Actuellement, 30 à 50% des patients sélectionnés pour une revascularisation rénale ont une fonction rénale altérée. L'histoire naturelle des sténoses rénales (surtout les lésions athéroscléreuses) montre une évolutivité vers l'obstruction progressive avec perte de parenchyme fonctionnel. Une revascularisation rénale envisage soit la protection du capital néphronique (intervention prophylactique), soit un sauvetage néphronique (restauration ou stabilisation d'une fonction rénale déjà altérée). Les critères prédictifs de bénéfice à long terme sont analysés. Les rôles respectifs de l'angioplastie transluminale percutanée et de la chirurgie sont discutés. L'intérêt de la revascularisation rénale sur la fonction rénale a été apprécié chez 23 malades réno-vasculaires et azotémiques (créatinine > 20 mg/l) ainsi que chez 8 patients en oligoanurie d'origine ischémique.

[more ▼] Cytokines are potent regulators of the chondrocyte functions. Some of them are produced by chondrocytes and interact to regulate cartilage metabolism. In this study, we investigated the production of interleukin-1 beta (IL-1 beta), IL-6, IL-8 and leukemia inhibitory factor (LIF) by human chondrocytes and examined the modulation of their secretion by exogenous cytokines. Human articular chondrocytes were isolated from their extracellular matrix by a triple successive enzymatic digestion of the cartilage. Subsequently, chondrocytes were stimulated by increased amounts of human recombinant cytokines [IL-1 beta, tumour necrosis factor alpha (TNF alpha), IL-8, LIF, IL-6]. IL-1 beta, IL-6, IL-8 and LIF were assayed into culture media and inside cell extracts by specific enzyme amplified sensitivity immunoassays (EASIAs). Under these experimental conditions, we have identified various interactions between cytokines. IL-beta and TNF alpha highly stimulated IL-6, LIF and IL-8 productions. IL-6 decreased IL-8 synthesis and increased LIF production. IL-8 slightly enhanced IL-6 production. Finally, LIF stimulated IL-1 beta, IL-6 and IL-8 productions. Using neutralizing antibodies against IL-1, we demonstrated that the effects of LIF were secondary to the stimulation by LIF of IL-1 beta production by the chondrocytes. In conclusion, chondrocytes secrete a variety of immunocompetent cytokines including IL-1 beta, IL-6, IL-8 and LIF that can interact to regulate chondrocytes metabolism. These results also define new biological activities of LIF and IL-6, and raise questions concerning their role in the pathogenesis of joint diseases.

[more ▼] Ocular inflammations may be due to a variety of diseases, and microorganisms play a major role in both acute and chronic eye diseases. Treatment of serious infections needs a good microbiological diagnostic. The indications and techniques for investigations are determined by the site of infection, severity of the process, and knowledge of the likely responsible organisms. Immediate inoculation of specimens on culture media in the examining room is often recommended. This article describes organisms associated with ocular infections, and is designed to assists ophthalmologists in the collection, processing and transport of specimens.
