Anti-inflammatory and antiosteo-clastogenesis properties of endogenous melanocortin receptor type 3 in experimental arthritis
No full textThe development of biological therapies has improved management of rheumatoid arthritis. However, costs and unresponsiveness to therapy in a sizeable proportion of patients limit their use, making it imperative to identify new targets for drug development programs. Here we investigated the melanocortin-receptor type 3 (MC3) pathway. Gene-deficient mice were subjected to a model of serum-transfer-induced arthritis and joints analyzed for gene expression (cytokines, MCs) and morphology. Pharmacological analyses were also conducted in this model. Osteoclastogenesis was studied from bone marrow cells. Mc3−/− mice displayed an exacerbated inflammatory arthritis, associated with prominent bone erosion and higher articular expression of Rankl. Osteoclastogenesis studied from Mc3−/− bone marrow cells revealed a higher degree of responsiveness to Rankl, linked to prolonged NF-κB activation compared to wild types. Up-regulation of a discrete set of inflammatory genes, including Il-1β, Il-6, and Nos2, was measured in Mc3−/− mice, and a marked up-regulation of joint Mc3 accompanied arthritis resolution in wild-type mice. Administration of an MC3 agonist, D[Trp8]-γ-MSH, attenuated disease incidence and severity in wild-type but not Mc3−/− mice. Overall, these findings identify MC3-mediated signaling as a beneficial pathway in experimental arthritis; hence this receptor is a novel target for the development of therapeutics for arthritis.—Patel, H.

Optimal activity and thermostability of xylose reductase from Debaryomyces hansenii UFV-170
No full textTo identify the most suitable operating conditions for xylose reductase (XR) activity of Debaryomyces hansenii UFV-170, a 2^2 central composite design face-centered (CCF) was used in this work, varying pH and temperature in the ranges 4–8 and 25–55°C, respectively. The results collected for two response variables, specifically the volumetric and the specific activities, were worked out by Response Surface Methodology. The XR stability was also investigated after storage at different temperatures

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

A diversity of resistance sources to Fusarium oxysporum f. sp. pisi found within grass pea germplasm
No full textPurpose: Grass pea is a legume species with recognized resistance to several diseases and thus important for the improvement of related major legume crops. It is infected by the soil-borne fungus Fusarium oxysporum f. sp. pisi (Fop), known as causal agent of pea fusarium wilt. We aim to identify, among grass pea, new sources of resistance against Fop and characterize the detected resistance mechanisms. Methods: A grass pea worldwide collection of accessions was characterized under controlled conditions for response to Fop race 2. Fungal colonization dynamics and potential resistance mechanisms were studied through confocal laser scanning microscopy (CLSM) using Fop race 2 expressing green fluorescent protein (GFP). Results: A quantitative nature of resistance to Fop, ranging from highly to partially resistant and susceptible accessions was detected, with resistance being the most frequent phenotype. Diverse colonization patterns were observed, suggesting the existence of different resistance mechanisms. In the highly resistant accessions, absence of fungal colonization in the vascular tissue was detected, while fungal progression was arrested at the level of roots both in highly resistant and partially resistant accessions. Conclusions: The resistant accessions identified here can be exploited in grass pea breeding for fusarium wilt resistance, and due to the phylogenetic relatedness to pea, potentially contribute to pea improvement
