Using the Morris Water Maze to Assess Spatial Learning and Memory in Weanling Mice

17.04.2015 | Christopher D. Barnhart et al., PLoS ONE, 2015

by Christopher D. Barnhart, Dongren Yang, Pamela J. Lein Mouse models have been indispensable for elucidating normal and pathological processes that influence learning and memory. A widely used method for assessing these cognitive processes in mice is the Morris water maze, a classic test for ...

T‐DNA insertion in aquaporin gene AtPIP1;2 generates transcription profiles reminiscent of a low CO2 response

07.04.2015 | ANASTASSIA BOUDICHEVSKAIA, MARLIES HECKWOLF, RALF KALDENHOFF, Plant, Cell & Environment, 2015

Abstract Results from CO2 diffusion studies and characterization of Arabidopsis thaliana aquaporin AtPIP1;2 T‐DNA insertion lines support the idea that specific aquaporins facilitate the diffusion of CO2 through biological membranes. However, their function as CO2 diffusion facilitators in ...

Biochar Mitigates Salinity Stress in Potato

06.04.2015 | S. S. Akhtar, M. N. Andersen, F. Liu, Journal of Agronomy and Crop Science, 2015

Abstract A pot experiment was conducted in a climate‐controlled greenhouse to investigate the growth, physiology and yield of potato in response to salinity stress under biochar amendment. It was hypothesized that addition of biochar may improve plant growth and yield by mitigating the ...

Changes in the physical properties of honey powder during storage

03.04.2015 | Katarzyna Samborska, Elwira Langa, Sławomir Bakier, International Journal of Food Science & Technology, 2015

Summary Honey powders produced by spray drying with the addition of Arabic gum and sodium caseinate were characterised in terms of the influence of storage time on the following physical properties: particle size, moisture content, water activity, bulk density, flowability and hygroscopicity. ...

Effect of the Ostreolysin A/Pleurotolysin B Pore-Forming Complex on Neuroblastoma Cell Morphology and Intracellular Ca2+ Activity

01.04.2015 | Milka Vrecl; Monika Babnik; Uroš Diacci; Evelyne Benoit; Robert Frangež, Toxicological Sciences, 2015

Ostreolysin A (OlyA) and pleurotolysin B (PlyB), isolated from edible oyster mushrooms, form a cytolytic complex (OlyA/PlyB) in membrane cells that causes respiratory arrest. This study evaluated the mechanisms underlying cytotoxic OlyA/PlyB activity in neuroblastoma NG108-15 cells. Confocal ...

Positive effects of the traditional Chinese medicine MLC901 in cognitive tasks

30.03.2015 | T. Lorivel, C. Gandin, J. Veyssière, M. Lazdunski, C. Heurteaux, Journal of Neuroscience Research, 2015

MLC901 (NurAiDII) is used as a treatment for stroke patients. It has been shown that MLC901 improves motor and cognitive recovery in ischemic and traumatic brain‐injured rodents. The present study seeks to delineate cognitive effects induced by MLC901 in normal, noninjured mice. To this end, the ...

Simultaneous determination of three banned psychiatric drugs in pig feed and tissue using solid‐phase reactor on‐line oxidizing and HPLC‐fluorescence detection

25.03.2015 | Liang Qi, Li‐Min Duan, Xiao‐Huan Sun, Jing Zhang, Zhi‐Qi Zhang, Biomedical Chromatography, 2015

Abstract The banned addition of psychiatric drugs such as phenothiazines to animal feed and foodstuffs increases the risk of human organ lesion. Phenothiazines usually exhibit weak native fluorescence and can be oxidized to strongly fluorescent compounds. In this study, a novel, sensitive and ...

Separating water‐potential induced swelling and shrinking from measured radial stem variations reveal a cambial growth and osmotic concentration signal

23.03.2015 | TOMMY CHAN, TEEMU HÖLTTÄ, FRANK BERNINGER, HARRI MÄKINEN, PEKKA NÖJD, MAURIZIO MENCUCCINI, EERO NIKINMAA, Plant, Cell & Environment, 2015

Abstract The quantification of cambial growth over short time periods has been hampered by problems to discern between growth and the swelling and shrinking of a tree stem. This paper presents a model, which separates cambial growth and reversible water‐potential induced diurnal changes from ...

Highly Porous Gelatin Reinforced 3D Scaffolds for Articular Cartilage Regeneration

19.03.2015 | Sofia Amadori, Paola Torricelli, Silvia Panzavolta, Annapaola Parrilli, Milena Fini, Adriana Bigi, Macromolecular Bioscience, 2015

3D highly porous (93% total porosity) gelatin scaffolds were prepared according to a novel, simple method, which implies gelatin foaming, gelification, soaking into ethanol and successive freeze‐drying. Reinforcement of the as‐prepared scaffolds (GEL) was performed through immersion in aqueous ...

Marine Drugs, Vol. 13, Pages 1360-1374: Structural Analysis and Anti-Complement Activity of Polysaccharides from Kjellmaniella crsaaifolia

16.03.2015 | Zhang, Wenjing ; Jin, Weihua ; Sun, Delin ; Zhao, Luyu ; Wang, Jing ; Duan, Delin ; Zhang, Quanbin, Marine Drugs, 2015

Two polysaccharides, named KCA and KCW, were extracted from Kjellmaniella crassifolia using dilute hydrochloric acid and water, respectively. Composition analysis showed that these polysaccharides predominantly consisted of fucose, with galactose, mannose and glucuronic acid as minor components. ...
