The antidepressant fluoxetine restores plasticity in the adult visual cortex     

Maya Vetencourt JF  Sale A  Viegi A  Baroncelli L  De Pasquale R  O'Leary OF  Castrén E  Maffei L 《Science (New York, N.Y.)》2008,320(5874):385-388

We investigated whether fluoxetine, a widely prescribed medication for treatment of depression, restores neuronal plasticity in the adult visual system of the rat. We found that chronic administration of fluoxetine reinstates ocular dominance plasticity in adulthood and promotes the recovery of visual functions in adult amblyopic animals, as tested electrophysiologically and behaviorally. These effects were accompanied by reduced intracortical inhibition and increased expression of brain-derived neurotrophic factor in the visual cortex. Cortical administration of diazepam prevented the effects induced by fluoxetine, indicating that the reduction of intracortical inhibition promotes visual cortical plasticity in the adult. Our results suggest a potential clinical application for fluoxetine in amblyopia as well as new mechanisms for the therapeutic effects of antidepressants and for the pathophysiology of mood disorders.  相似文献   

A study of the prevalence of methicillin-resistant Staphylococcus aureus in pigs and in personnel involved in the pig industry in Ireland     

Horgan M  Abbott Y  Lawlor PG  Rossney A  Coffey A  Fitzgerald GF  McAuliffe O  Paul Ross R 《Veterinary journal (London, England : 1997)》2011,190(2):255-259

To evaluate the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in the pig population in Ireland, nasal swabbing was employed in three abattoirs to screen 440 pigs from 41 geographically distributed farms. One hundred individuals involved in the pig industry were also nasally screened. No MRSA isolates were recovered from the pigs and only two of the humans tested were identified as MRSA carriers. Importantly, MRSA was not obtained from pig producers, veterinarians or abattoir employees, but was isolated from individuals working in the wider pig industry. Multi-locus sequence typing revealed that these isolates belonged to sequence types (ST) ST22 and ST1307; the latter is a previously unreported single locus variant of ST5. Five dust samples from each of the three slaughterhouses were culture-negative for MRSA. These results indicate that porcine colonisation by MRSA, and in particular the animal-related strain MRSA-ST398, was not common in Ireland during the period of study.  相似文献   

Intraocular ALλ amyloidoma with plasma cell neoplasia in a cat     

Kershaw O  Linek J  Linke RP  Gruber AD 《Veterinary ophthalmology》2011,14(Z1):88-92

An 11-year-old, neutered male domestic short-hair cat was presented with buphthalmos of the right eye and diagnosed with advanced glaucoma. Sonographic examination revealed an iridial thickening. Neoplasia was suspected and an enucleation was performed. Histopathology of the enucleated eye revealed abundant amyloid deposition predominantly in the anterior uveal tract accompanied by few to moderate numbers of well-differentiated plasma cells. The amyloid deposits were identified by staining with Congo red and showing green birefringence under polarized light. Immunohistochemically, amyloid and plasma cells stained intensely only with anti-ALλ antibody, supporting the amyloid tumor being an immunoglobulin-λ-light chain origin. Additional abnormalities included narrowing of the filtration angle and collapse of the ciliary cleft, and trabecular meshwork. One year post-enucleation, the cat was still healthy without signs of systemic amyloidosis or apparent metastatic disease. This is the first report of a cat with noncutaneous extramedullary plasmacytoma originating in the anterior uveal tract with resulting local amyloid.  相似文献   

传统价值观认同度初探     

王洁  何霓  Olivia Yu 《安徽农业大学学报》2014,(3):42-48

国民价值取向的发展与演变是政府制定经济与社会政策的重要基础,直接关系到构建和谐社会的策略。在从传统社会向现代社会转型的过程中,中国传统的基本价值观念发生了哪些变化,当今人们对传统价值观的认同度如何,不同群体的价值观念有何差异等问题值得探讨。通过对问卷所收集的数据进行统计分析,对影响价值观的认知体系做尝试性的探讨,调查结果表明,现阶段民众对传统价值观仍有较高的认同度,但不同群体之间的代际差异显著。  相似文献

Sequencing of variable regions of the 16S rRNA gene for identification of lactic acid bacteria isolated from the intestinal microbiota of healthy salmonids     

Balcázar JL  de Blas I  Ruiz-Zarzuela I  Vendrell D  Gironés O  Muzquiz JL 《Comparative immunology, microbiology and infectious diseases》2007,30(2):111-118

The aim of this study was to identify lactic acid bacteria (LAB) using polymerase chain reaction (PCR) amplification of variable regions of the 16S rRNA gene. Thirteen LAB strains were isolated from the intestinal microbiota of healthy salmonids. A approximately 500-bp region of the highly conserved 16S rRNA gene was PCR-amplified and following this, a portion of the amplicon (272-bp) including the V1 and V2 variable regions was sequenced. The sequence containing both the V1 and V2 region provided strong evidence for the identification of LAB. The LAB strains were identified as Carnobacterium maltaromaticum, Lactobacillus curvatus, Lactobacillus sakei, Lactobacillus plantarum, Lactococcus lactis subsp. cremoris, Lactococcus lactis subsp. lactis, and Leuconostoc mesenteroides. The method described was found to be a very simple, rapid, specific, and low-cost tool for the identification of unknown strains of LAB.  相似文献

Acibenzolar-S-methyl doses and application methods to Pratylenchus brachyurus control in maize     

Michelly Ragazzi Cardoso  Heriksen Higashi Puerari  Isabela Hernandes  Olivia Diulen Costa Brito  Júlio César Antunes Ferreira  Claudia Regina Dias-Arieira 《Acta Agriculturae Scandinavica, Section B - Plant Soil Science》2017,67(1):23-27

Pratylenchus brachyurus is one of the main limiting factors of agricultural yield in annual crops, particularly due its difficult management. Methods to reduce populations are constantly sought, and the use of resistance inducers deserves attention. Thus, the study aimed to assess the effect of acibenzolar-S-methyl (ASM) application in different doses to P. brachyurus control in maize. Initially, 1000 specimens of P. brachyurus were inoculated in maize for the multiplication. After 60 days, the aerial part (AP) was discarded and maize was sown under the treatments: seed treatment (ST), application in the AP and ST?+?AP, in the doses of 0.125, 0.25, 0.5 and 1.0?g i.a./L. Vegetative and nematological parameters were assessed 60 days later. ASM did not affect plant growth, but reduced nematode population in all the treatments. The treatment methods did not differ and reduced the number of nematodes/g root by 64.25 to 80.14% compared to the control. The doses of 0.6, 0.51 and 0.65?g i.a./L promoted the most reductions in the number of nematodes/g root when applied in ST, AP and ST?+?AP, respectively. Thus, we recommend the use of ASM applied on shoot in a dose of 0.50?g i.a./L.  相似文献   

Phospholipid, sphingolipid, and fatty acid compositions of the milk fat globule membrane are modified by diet     

Lopez C  Briard-Bion V  Menard O  Rousseau F  Pradel P  Besle JM 《Journal of agricultural and food chemistry》2008,56(13):5226-5236

The phospholipid and sphingolipid composition of milk is of considerable interest regarding their nutritional and functional properties. The objective of this article was to determine the lipid composition of the milk fat globule membrane (MFGM) of milk from cows fed a diet rich in polyunsaturated fatty acids. The experiments were performed with 2 groups of 6 cows feeding on (i) maize silage ad libitum (+ grassland hay, mixture of cereals, soyabean meal) or (ii) the maize silage-based diet supplemented with extruded linseed (bringing a lipid proportion of 5% of dry matter). The phospholipid and sphingolipid composition of the MFGM was determined using HPLC/ELSD. The fatty acid (FA) composition of total lipids and phospholipids was determined using GC. As expected, the linseed-supplemented diet decreased the saturated FA and increased the unsaturated FA content in milk fat. MFGM in milk from cows fed the diet rich in polyunsaturated FA resulted in (i) a higher amount of phospholipids (+ 18%), which was related to a smaller size of milk fat globules (ii) an increase of 30% (w/w) of the concentration in sphingomyelin, (iii) a higher content in stearic acid (1.7-fold), unsaturated FA (1.36-fold), and C18:1 trans FA: 7.2 +/- 0.5% (3.7-fold). The MFGM contained a higher concentration of unsaturated FA (C18:1, C18:2, and C18:3) and very long-chain FA (C22:0, C23:0, C24:0, EPA, DHA) compared with total lipids extracted from milk. The technological, sensorial, and nutritional consequences of these changes in the lipid composition of the MFGM induced by dietary manipulation remain to be elucidated.  相似文献
